Description

shelter

The present invention relates to shelters.

For a good night's sleep, bedding (for example, pillows and beds) that makes it easier to turn over can be mentioned. However, at present, the number of people who are engaged in irregular work such as shift work and night work is increasing, and it is assumed that only bedding is insufficient as an environment for achieving a good night's sleep.

In fact, medical personnel who work at hospitals may have residences near hospitals, residences facing main roads, or residences near police stations or fire stations. However, those who live in these areas are often awakened by the sirens of police cars, ambulances and fire trucks. In addition, if you live in a crime-prone area or near the coast where there is no breakwater of sufficient strength or height, it is difficult to maintain a sense of security due to the fear of flooding, high waves and tsunami. is easily imagined.

Preparing a sleeping environment that combines such soundproofing, crime prevention, and disaster prevention, and that takes into account claustrophobia or restlessness in large spaces derived from the experiences of each individual, can lead to sleep problems such as sleep disorders. It is thought that it is also necessary for the sound sleep of quite a few people. On the other hand, good sleep includes the elimination of fatigue in various parts of the body upon awakening, the disappearance of fatigue, the disappearance of headaches, heavy headaches, and muscle pain, the feeling of sound sleep, the enhancement of thinking, memory, and concentration, and the positive thinking. Subjective sensations that cannot be quantified, such as whether the energy, posture, and way of thinking are born, and the disappearance of drowsiness. It is important along with not having to wake up early in the morning or feel lack of sleep.

It is said that light is important for one of the biological clocks. It is well known that exposure to the morning sun promotes the secretion of physiologically active substances such as sleep-related hormones such as melatonin. Many people suffer from migraine headaches before waking up due to changes in atmospheric pressure. By the way, there are probably more than a few people who have been unable to get a good night's sleep due to concerns about security, noise from the next room, earthquakes, and power outages while traveling. It is self-evident that such a great sense of security plays an extremely important role.

However, especially in Japan, natural disasters such as earthquakes, tsunamis, volcanic eruptions, typhoons, torrential rains, and other natural disasters occur every year. Moreover, wooden houses still occupy the majority in Japan, and it is difficult to obtain a great sense of security, including fires. Furthermore, although the current novel coronavirus infection may subside in a few years, it is expected that a major pandemic will occur once every ten years in the future. Then, in the event of a natural disaster, going to an evacuation center rather leads to an increased risk of infection, and may put oneself in an environment far from comfortable sleep, such as a loss of a sense of security.

In addition, in recent years, it has become essential to maintain a wide variety of social infrastructures such as production, logistics, transportation, finance, medical care, and nursing care. However, people who work to maintain such social infrastructure are naturally forced to work shifts unrelated to their natural biological clocks, and many of them suffer from various sleep disorders. Moreover, for this reason, there are not a few people who are complicated with mental and neurological diseases such as alcohol dependence and depression accompanied by sleep disorders. Naturally, the risk of diseases, including various lifestyle-related diseases such as cancer and diabetes, for people working in this kind of work is less than that for people who do not work shifts, probably because it is difficult to get enough good sleep. three times higher. For people who continue to work in the above working style, getting a good night's sleep is extremely important as it is directly linked to improving productivity and extending healthy life expectancy.

As described above, many people want a space where they can sleep soundly. For example, Patent Literature 1 discloses a shelter that can be used as a sleeping room during normal times, and can be used as an evacuation room in the event of flood damage (for example, tsunami or flood).

Patent No. 6816864

However, the technology of Patent Document 1 has room for improvement from the viewpoint of making the space in the shelter an environment suitable for sleeping. In consideration of the above circumstances, an object of the present invention is to provide a shelter whose internal space can be controlled to an environment suitable for sleep.

In order to solve the above problems, the shelter according to the present invention includes a housing part having an internal space where a user is located, a temperature adjustment device for adjusting the temperature in the internal space, and a humidity in the internal space. a humidity adjusting device that adjusts, an atmospheric pressure adjusting device that adjusts the pressure in the internal space, a first detection unit that is provided in the internal space and detects temperature, and a first detection unit that is provided in the internal space and detects humidity 2 detection units, a third detection unit that is provided in the internal space and detects atmospheric pressure, a temperature control unit that controls the temperature adjustment device according to the temperature detected by the first detection unit, and the second detection unit. a humidity control unit that controls the humidity adjustment device according to the humidity detected by the third detection unit; and an atmospheric pressure control unit that controls the atmospheric pressure adjustment device according to the atmospheric pressure detected by the third detection unit.

According to the shelter according to the preferred aspect of the present invention, it is possible to control the internal space to an environment (temperature, humidity and atmospheric pressure) suitable for sleep.

The temperature controller 421 of the first embodiment controls the temperature adjustment device 221 so that the internal space H is maintained at a desired temperature. Specifically, the temperature control section 421 controls the temperature adjustment device 221 according to the first detection signal P1 generated by the first detection section R1. For example, the temperature control unit 421 controls the temperature adjustment device 221 according to the result of comparing the temperature indicated by the first detection signal P1 and a predetermined threshold (hereinafter referred to as "first threshold"). Note that the first threshold is a value corresponding to the desired temperature.

Specifically, the temperature control unit 421 controls the temperature adjustment device 221 to adjust the temperature of the internal space H so that the temperature indicated by the first detection unit R1 approaches the first threshold value. For example, the temperature control unit 421 blows cooled air when the temperature indicated by the first detection signal P1 exceeds the first threshold, and blows cooled air when the temperature indicated by the first detection signal P1 is below the first threshold. controls the temperature control device 221 to blow heated air.

The first threshold is set, for example, according to a temperature suitable for sleep. Also, the first threshold may be changed over time. From the viewpoint of providing a comfortable sleep environment, a configuration in which the first threshold is set so as to gradually increase from the time of falling asleep to the time of waking up is preferable. Note that the first threshold may be arbitrarily set by the user U.

The humidity control unit 422 controls the humidity adjustment device 222 . The humidity control unit 422 of the first embodiment controls the humidity adjustment device 222 so that the internal space H is maintained at a desired humidity. Specifically, the humidity control section 422 controls the humidity adjustment device 222 according to the second detection signal P2 generated by the second detection section R2. For example, the humidity control unit 422 controls the humidity adjustment device 222 according to the result of comparing the humidity indicated by the second detection signal P2 and a predetermined threshold (hereinafter referred to as "second threshold"). Note that the second threshold is a value corresponding to the desired humidity.

Specifically, the humidity control unit 422 controls the humidity adjustment device 222 to adjust the humidity of the internal space H so that the humidity indicated by the second detection unit R2 approaches the second threshold. For example, the humidity control unit 422 dehumidifies the internal space H when the humidity indicated by the second detection signal P2 exceeds the second threshold, and dehumidifies the internal space H when the humidity indicated by the second detection signal P2 is below the second threshold. , the humidity control device 222 is controlled to humidify the internal space H.

The second threshold is set, for example, according to the humidity suitable for sleep. In addition, the user U may arbitrarily set the second threshold.

The atmospheric pressure control unit 423 controls the atmospheric pressure adjustment device 223 . The atmospheric pressure control unit 423 of the first embodiment controls the atmospheric pressure adjustment device 223 so that the internal space H is maintained at a desired atmospheric pressure. Specifically, the atmospheric pressure control section 423 controls the atmospheric pressure adjustment device 223 according to the third detection signal P3 generated by the third detection section R3. For example, the air pressure controller 423 controls the air pressure adjustment device 223 according to the result of comparing the air pressure indicated by the third detection signal P3 and a predetermined threshold (hereinafter referred to as "third threshold"). Note that the third threshold is a value corresponding to the desired atmospheric pressure.

Specifically, the atmospheric pressure control unit 423 controls the atmospheric pressure adjustment device 223 to adjust the temperature of the internal space H so that the atmospheric pressure indicated by the third detection unit R3 approaches the third threshold value. For example, when the atmospheric pressure indicated by the third detection signal P3 exceeds the third threshold, the atmospheric pressure control unit 423 discharges air so as to reduce the atmospheric pressure in the internal space H, and controls the atmospheric pressure indicated by the third detection signal P3. is below the third threshold, the air pressure adjustment device 223 is controlled so that air is supplied into the internal space H from the outside.

The third threshold is set, for example, according to air pressure suitable for sleep. Note that the third threshold may be arbitrarily set by the user U.

As can be understood from the above description, the temperature, humidity and atmospheric pressure of the internal space H are controlled. Therefore, the internal space H can be made into an environment suitable for sleep.

The shelter 200 according to the first embodiment preferably employs configuration A or configuration B described below.

FIG. 3 is a configuration diagram of a shelter 200A that employs configuration A. Configuration A is a configuration that can run on both water and land. Shelter 200A has a function as a so-called amphibious vehicle. Configuration A employs known amphibian technology. For example, shelter 200A includes tires 250 that can run on land, floats 260 that generate buoyancy on water, and screws 270 that can run on water. In addition, various devices for controlling running on water and running on land are mounted on the shelter 200A.

FIG. 4 is a configuration diagram of a shelter 200B that employs configuration B. Configuration B is a submersible configuration. The shelter 200B functions as a so-called submarine. Configuration B employs known submarine technology. For example, the shelter 200B comprises a compressed air tank 280, a ballast tank 281 filled with air from the compressed air tank 280, and a vent valve 282 for releasing the air in the ballast tank 281. The shelter 200B releases the air in the ballast tank 281 and fills the ballast tank 281 with seawater when diving underwater. In addition, various devices for controlling diving are mounted on the shelter 200B.

Considering the occurrence of disasters (such as earthquakes, tsunamis, volcanic eruptions, typhoons, or torrential downpours), configuration A and configuration B are preferable. In particular, considering the frequent occurrence of flood damage due to abnormal weather, landslides, floods, tsunamis, etc. in various parts of the world, providing a sense of security not only in normal times but also in emergencies is extremely significant for a good night's sleep. . Considering the above circumstances, configuration A and configuration B are particularly suitable. In addition, from the viewpoint of ensuring the control of the air pressure in the internal space H, the configurations A and B are preferable.
However, adopting configuration A or configuration B in shelter 200 is not essential. For example, the shelter 200 may be stationary indoors or outdoors.

In FIG. 1, the processing device 240 is provided between the outer wall portion 21A and the inner wall portion 21C. A configuration in which the processing device 240 is provided is preferable. On the other hand, from the viewpoint of preventing the processing device 240 from colliding with the user U when the shelter 200 vibrates due to an earthquake or the like, the configuration provided outside the internal space H is preferable.

In addition, the shelter 200 is also preferably configured to have a power generation mechanism (solar panel) capable of self-power generation in preparation for disasters. The power generation mechanism is provided, for example, on the outer surface of the outer wall of the housing section 210 . When it becomes difficult to secure power from the outside during a disaster (that is, when there is a power outage), power is supplied from the power generation mechanism to the shelter 200 . Therefore, even if a power failure occurs, it is possible to maintain the interior space H in a comfortable environment.

<Second embodiment>
A second embodiment of the present invention will be described. In addition, in each embodiment illustrated below, the reference numerals used in the description of the first embodiment are used for elements having the same actions or functions as those of the first embodiment, and detailed description of each element is appropriately omitted.

In the second embodiment, air whose temperature and humidity are adjusted for each part of the user's U body is controlled to be blown from the air conditioning unit 90 . FIG. 5 is a conceptual diagram conceptually showing the relationship between air blown by the air conditioning unit 90 and each part of the user according to the second embodiment. FIG. 5 illustrates a configuration for controlling the temperature and humidity for each of the head M1, body M2, and leg M3. As illustrated in FIG. 5, an air conditioning unit 90 is installed for each part M (M1 to M3) of the user U. That is, the vent N1 and the vent N2 are also provided for each part M of the user U. As shown in FIG. The configuration of each air conditioning unit 90 is the same as in the first embodiment.

It can also be said that the internal space H is conceptualized as a plurality of areas (hereinafter referred to as "unit areas") T1 to T3 respectively corresponding to a plurality of parts M1 to M3 of the user. That is, an air conditioning unit 90 is provided for each unit area T (T1 to T3) to adjust the temperature and humidity.

In the second embodiment, a plurality of first detection units R1 and a plurality of second detection units R2 are installed in the internal space H. For example, a first detection section R1 and a second detection section R2 are provided at positions corresponding to respective parts in the internal space H. As shown in FIG. That is, the number of the first detection units R1 and the number of the second detection units R2 corresponding to the number of parts are provided in the internal space H.

The temperature control unit 421 of the second embodiment controls the temperature detected by the first detection unit R1 corresponding to the unit region T (the temperature indicated by the first detection signal P1) for each of the plurality of unit regions T (T1 to T3). ) to control the temperature control device 221 . The first threshold is also set individually for each unit region T. FIG. As can be understood from the above description, it is possible to control the temperature of each unit region T individually.

For example, the first threshold value of each unit area T is set so that the temperature near the head M1 of the user U is low and the temperature is high toward the legs M3 of the user U (so-called cold head and foot temperature). set. For example, the first threshold for the head M1 is set to 20°C to 22°C, the first threshold for the trunk M2 is set to 23°C to 25°C, and the first threshold for the leg M3 is set to 24°C to 24°C. Set to 26°C.

The humidity control unit 422 of the second embodiment detects the humidity detected by the second detection unit R2 corresponding to the unit region T (the humidity indicated by the second detection signal P2) for each of the plurality of unit regions T (T1 to T3). ) to control the humidity control device 222 . The second threshold is also set individually for each unit region T. FIG. As understood from the above description, it is possible to control the humidity for each unit region T individually.

As can be understood from the above description, in the second embodiment, the temperature and humidity are individually controlled for each air conditioning unit 90 corresponding to the unit area T. and humidity can be set. Therefore, in order to realize a good sleep, for example, it is possible to create a state close to cold head and warm feet. The number of the first detection portions R1 and the second detection portions R2 provided in each unit region T is arbitrary.

<Modified example according to the first and second embodiments>
Each form illustrated above can be variously modified. Specific modification modes are exemplified below. It is also possible to appropriately combine two or more aspects arbitrarily selected from the following examples.

(1) In each form described above, the size of the shelter 200 (as well as the size of the internal space H) is arbitrary. Each user U has a different sense of the size of the space in which they are located. For example, some users U feel restless when in a large space, and some users U feel uneasy when in a small space. Therefore, for example, a shelter 200 (capsule-shaped shelter 200) having an internal space H large enough to accommodate only bedding B is preferable for a user U who feels secure in a narrow space. On the other hand, the shelter 200 with the large internal space H is preferable for the user U who feels fear and anxiety in a narrow space. In addition, it is preferable not to install any furniture other than the bedding B in the internal space H as much as possible from the viewpoint of preventing the furniture, etc. installed in the internal space H from being placed under the furniture in the event of a disaster.

(2) In each of the above embodiments, as illustrated in FIG. 6, the shelter 200 may include a lighting device 225 that illuminates the internal space H and a light intensity control unit 428 that controls the light intensity of the lighting device 228. . When lighting is installed in the internal space H, it is preferable to use indirect lighting. If lighting is installed, it should be turned off during sleep (immediately after going to bed and within 15 minutes), and the luminous intensity should be adjusted from a predetermined time before waking up (for example, 30 to 60 minutes before waking up) to waking up. is set to increase stepwise. A well-known technique is adopted for the method of estimating the time of going to bed and the time of waking up. For example, the wake-up time is estimated using a sensor that detects user U's biological information (for example, pulse, respiration rate, or body movement). Also, the user U may set a wake-up time scheduled before sleeping.

(3) In each of the above embodiments, the shelter 200 may be equipped with an acoustic device that emits sound into the internal space H. When the user U sleeps, a sound device may emit a sound for inducing sleep (for example, regular sound such as the sound of waves, the sound of a babbling brook, or the sound of a train). Also, when waking up, an alarm sound (a sound that does not cause discomfort as much as possible) may be emitted from the sound device.

As can be understood from the above description, both sound and lighting (light) can promote comfortable sleep and wake-up for the user U.

(4) In each of the above-described forms, when the user does not get up after the scheduled time (when the weight load on the bedding B does not disappear), a configuration is adopted to encourage the user to get up. In the above configuration, for example, the sensor that detects the load of the user U is mounted on the bedding B, and the vibration device is mounted on the shelter 200 . The vibrating device can be installed anywhere as long as vibration is propagated to the user U. For example, it is installed inside the bedding B or under the floor in the internal space H. When the scheduled wake-up time has passed, the wake-up of the user U is promoted by opening the vibration device.

(5) In each of the above embodiments, a sensor that detects the number of spontaneous respirations of the user U may be provided. From the number of spontaneous respirations, the number of respirations during sleep is calculated. Also, from the tendency of the awakening response index, the calculation of the number of respirations due to nasal breathing, which is parasympathetic dominant, is calculated. The number of respirations during sleep and the number of respirations due to nasal breathing may be used for estimating the feeling of comfortable sleep of the user U. Note that any known technique (for example, calculation using a learned model) is employed to specify the number of breaths during sleep and the number of breaths due to nasal breathing.

(6) In each form described above, the type of bedding B installed in the internal space H is arbitrary. For example, a bedding B that is hung like a hammock and a stationary bedding B that has a plurality of pillars with a seismic isolation structure are installed in the internal space H.

(7) In each of the above-described embodiments, the external structure of the shelter 200 including the outer wall 21A is preferably fireproof, earthquakeproof, and watertight.

(8) In each of the above-described forms, various configurations can be adopted for the shelter 200 other than the configurations A and B described above. For example, a configuration in which the entire shelter 200 floats on water is also suitable. In the above configuration, for example, the shelter 200 is fixed with an impact-resistant anchor or the like to prevent it from being washed away by water.

(9) In each of the above embodiments, the temperature control section 421, the humidity control section 422, the air pressure control section 423, and the light intensity control section 428 may be controlled as follows.

The temperature control unit 421 may control the temperature control device using the first learned model that has learned the relationship between the degree of good sleep and temperature. Specifically, the first threshold is set according to the result input to the first trained model. It should be noted that the user U inputs the degree of good sleep to the processing device 240 after waking up. Then, the processing device 240 causes the first learned model to learn the relationship between the temperature (first threshold value) set during sleep of the user U and the input degree of comfortable sleep.

The humidity control unit 422 may control the humidity control device using a second learned model that has learned the relationship between the degree of good sleep and humidity. Specifically, the second threshold is set according to the result input to the second trained model. It should be noted that the user U inputs the degree of good sleep to the processing device 240 after waking up. Then, the processing device 240 causes the second trained model to learn the relationship between the humidity (second threshold value) set during sleep of the user U and the inputted degree of comfortable sleep.

The atmospheric pressure control unit 423 may control the atmospheric pressure control device using a third learned model that has learned the relationship between the degree of good sleep and atmospheric pressure. Specifically, the third threshold is set according to the result input to the second trained model. It should be noted that the user U inputs the degree of good sleep to the processing device 240 after waking up. Then, the processing device 240 causes the third learned model to learn the relationship between the atmospheric pressure (third threshold value) set when the user U is sleeping and the inputted degree of comfortable sleep.

The light intensity control unit 428 controls the lighting device 228 according to the result of inputting the data representing the user's degree of sleep into the fourth trained model that has learned the relationship between the degree of sound sleep and the light intensity. It should be noted that the user U inputs the degree of good sleep to the processing device 240 after waking up. Then, the processing device 240 causes the fourth trained model to learn the relationship between the luminous intensity of the lighting device 228 set when the user U is sleeping and the inputted degree of comfortable sleep.

According to the above configuration, it is possible to individually set the optimum temperature, humidity, atmospheric pressure, and luminous intensity for each user U. The degree of comfortable sleep is input by the user based on, for example, a plurality of levels (for example, 5 is the most comfortable sleep in a 5-level evaluation).

A trained model is a statistically estimated model generated by machine learning. Various statistical estimation models such as decision trees or neural networks are preferably used as trained models. A trained model is realized by a combination of a program (for example, a program module constituting artificial intelligence software) that causes the control device 31 to execute an operation for generating output data from input data, and a plurality of coefficients applied to the operation. be. A plurality of coefficients are set by machine learning (especially deep learning) using a large amount of teacher data and stored in the storage device 242 .

The data added to the first learned model, the second learned model, the third learned model, and the fourth learned model are not limited to the degree of good sleep, temperature, humidity, air pressure, and light intensity. For example, the first trained model, the second trained model, the third trained model, and the fourth trained model may take into account the region/region where the user U is located, the season, the weather, and the like. . As can be understood from the above description, in addition to the fact that the housing unit 210 of the shelter 200 can provide soundproofing and vibrationproofing, the user U's part M (head area) is continuously fed back by the learned model. It is possible to control the temperature/humidity, air pressure, and light intensity for each part (parts, torso, and legs) to achieve a good sleep.

(11) In each of the above embodiments, an infrared monitor may be provided in the internal space H and a hygrometer may be provided near the body. During sleep, there is no exercise other than tossing and turning, so it is assumed that heat generated from muscles gradually decreases, sweating increases, body temperature decreases due to the heat of vaporization of sweat, and humidity increases. The infrared monitor is used to detect how the user U moves (rolls over) during sleep and changes in body temperature and humidity over time. Also, barometers for measuring the external and internal pressures may be provided outside and inside the shelter 200 .

(12) After spending several hours in a confined closed space, it is assumed that the oxygen concentration will gradually decrease. If the outside air is sufficiently fresh and the oxygen concentration is high, ventilation can solve the problem. Since the oxygen concentration is not sufficient in the sleeping space, it is necessary to supply oxygen from an oxygen tank in order to recover and reconfigure the air composition of the sleeping space.

In consideration of the above circumstances, the shelter 200 may be provided with a mechanism for adjusting the oxygen in the internal space H. FIG. 7 is a schematic diagram of a shelter 200 according to the modification, and FIG. 8 is a functional block diagram showing functions of the shelter 200 according to the modification. As illustrated in FIGS. 7 and 8, the shelter 200 includes a fourth detector R4, an oxygen controller 424, and an oxygen supply device 224. As shown in FIG.

The fourth detection unit R4 is a sensor that is provided in the internal space H and detects the concentration of oxygen in the internal space. Specifically, a fourth detection signal P4 indicating the oxygen concentration is generated. The fourth detection signal P4 is continuously generated at predetermined intervals. The oxygen supply device 224 (for example, an oxygen cylinder) supplies oxygen into the internal space H under the control of the oxygen control section 424 . The oxygen supply device 224 is, for example, incorporated inside the intermediate layer 21B and supplies oxygen into the internal space H through a vent N4 provided in the inner wall portion 21C.

The oxygen control unit 424 controls the oxygen supply device 224 according to the oxygen concentration detected by the fourth detection unit R4. Specifically, the oxygen adjusting section controls the oxygen supply device 224 according to the comparison result between the oxygen concentration indicated by the fourth detection signal P4 and a predetermined threshold value. First, the oxygen adjuster causes the oxygen supply device 224 to supply oxygen when the oxygen concentration indicated by the fourth detection signal P4 is below a predetermined threshold. For example, by opening the on-off valve of the oxygen supply device 224, the oxygen supply device 224 is made to supply oxygen. Second, the oxygen adjuster causes the oxygen supply device 224 to supply oxygen when the oxygen concentration indicated by the fourth detection signal P4 exceeds a predetermined threshold. For example, the supply of oxygen to the oxygen supply device 224 is stopped by closing the on-off valve of the oxygen supply device 224 .

It should be noted that the fourth detection unit R4 may be a sensor that detects carbon dioxide BR>Z degrees in the internal space H from the viewpoint of measuring the necessity and timing of ventilation. Further, the oxygen control unit 424 may control the oxygen supply device 224 using a learned model that has learned the relationship between the degree of comfortable sleep of the user U and the concentration of oxygen in the internal space H.

In addition, it is clear that bad odors, including smoke, also interfere with sleep during a fire, underwater or in the mountains. In consideration of the above circumstances, the shelter 200 may be provided with a mechanism for controlling the opening and closing of the valve device E in order to ventilate the internal space H appropriately.

As illustrated in FIGS. 7 and 8, the shelter 200 includes a valve control section 425 and a fifth detection section R5. A fifth detection unit R5 is provided in the internal space H and generates a fifth detection signal P5 indicating the concentration of harmful gas in the internal space. Harmful gases include, for example, various gases such as carbon monoxide gas, carbon dioxide gas, ammonia, and nitrogen oxide compounds.

The valve control section 425 controls the valve device E according to the comparison result between the concentration indicated by the fifth detection signal P5 generated by the fifth detection section R5 and a predetermined threshold value. Specifically, the valve control unit 425 opens the valve device E (that is, ventilates) when the concentration indicated by the fifth detection signal P5 exceeds a predetermined threshold value. On the other hand, the valve control unit 425 closes the valve device E (that is, stops ventilation) when the concentration indicated by the fifth detection signal P5 is below the predetermined threshold.

(13) The shelter 200 may be provided with a removal device (for example, an air purifier) for removing harmful substances such as dust, smoke, dust, pollen and smoke. Specifically, the air cleaner removes fine particles and odors in the internal space H, and operates continuously while the user U is sleeping. Also, the shelter 200 may be equipped with a deodorizing device (for example, activated carbon or bamboo charcoal) for removing odors.

Furthermore, the shelter 200 may include a static eliminator capable of eliminating static electricity generated in the internal space H. For example, a fan-type ionizer or the like that generates ions and blows them into the internal space H is used as the static eliminator. Note that the air purifier and the static eliminator are built in the internal space H or inside the intermediate layer 21B.

(14) A configuration in which AI (artificial intelligence) controls power consumption of the shelter 200 to a minimum is preferable.

(15) Good sleep is important not only for healthy users, but also for all people, including irregular workers such as shift workers and users suffering from autonomic imbalance such as weather diseases. In the shelter 200 according to one aspect of the present invention, a wide range of sleep environments, such as air pressure, temperature, humidity, luminosity, sound, vibration, oxygen concentration, static electricity, and odor, are individually optimized along with the passage of sleep from before falling asleep to waking up. Since it is controlled at any time to achieve a high level of comfort, the user can have a good sleep regardless of the season, weather, disaster, or the like. In addition, by resetting the disturbed body clock, it is possible to improve sleep disorders, autonomic imbalance, etc., which have been difficult to treat in the past.

<Third Embodiment>
In the first embodiment and the second embodiment, for example, the following bedding system 100 may be installed in the shelter.

9 is a plan view of the bedding system 100. FIG. The bedding system 100 is a system related to bedding for assisting the user U's sleep. As illustrated in FIG. 9, the bedding system 100 includes a mattress 20A (an example of “bedding”), an auxiliary mechanism 21, a temperature mechanism 22, a humidity mechanism 23, a processor 30, and a sensor unit 40. FIG. In the third embodiment, a mattress 20A on which the user U lies while sleeping is exemplified as bedding.

In the following description, the thickness direction of the mattress 20A will be referred to as the Z direction, the direction perpendicular to the Z direction will be referred to as the X direction, and the direction perpendicular to the Z and X directions will be referred to as the Y direction. In addition, in FIG. 9, let the horizontal direction of the mattress 20A be an X direction, and let the longitudinal direction of the mattress 20A be a Y direction. FIG. 10 is a side view of the mattress 20A viewed from the Y direction, and FIG. 11 is a side view of the mattress 20A viewed from the X direction.

The mattress 20A includes a container K, for example. The container K is made of, for example, a stretchable material. The container K includes a surface F on which the user U lies (hereinafter referred to as "contact surface"). The contact surface F is the surface of the mattress 20A on the positive side in the Z direction.

As illustrated in FIGS. 9 to 11, the auxiliary mechanism 21, the temperature mechanism 22 and the humidity mechanism 23 are built in the mattress 20A (container K). Although the auxiliary mechanism 21, the temperature mechanism 22, and the humidity mechanism 23 are not actually exposed to the outer surface of the mattress 20A, in FIGS. is illustrated. The mattress 20A can withstand a load of, for example, about 350 kg with the auxiliary mechanism 21, the temperature mechanism 22, and the humidity mechanism 23 built therein.

<Sensor unit 40>
FIG. 12 is a block diagram illustrating the functions of the bedding system 100 according to the third embodiment. As exemplified in FIG. 12, the sensor unit 40 is a detection device that generates detection signals V (V1, V2, V3) for specifying information about the biological body of the user U (hereinafter referred to as "biological information"). . A sensor unit 40 of the third embodiment includes a first acquisition section 41 , a second acquisition section 42 and a third acquisition section 43 .

The first acquisition unit 41 is a sensor that generates a detection signal V1 that is displaced on the contact surface F according to the load of the user U. For example, a piezoelectric element is exemplified as the first acquisition unit 41 . The detection signal V1 is based on the position of the user U on the mattress 20A (contact surface F) (hereinafter referred to as "body position") and the period elapsed since the user U recently changed his posture (hereinafter referred to as "change period"). It is used to identify the For example, a plurality of first obtaining portions 41 are provided at predetermined intervals in the region on the contact surface F side inside the mattress 20A (container K). However, the number of first acquisition units 41 is arbitrary.

The detection signal V1 generated by the first acquisition unit 41 corresponding to the position where the user U is located on the contact surface F among the plurality of first acquisition units 41 fluctuates. Therefore, it is possible to estimate the body position according to the detection signal V1. In addition, since the detection signal V1 generated by the first acquisition unit 41 is displaced when the user U moves, it is possible to detect a change in the posture of the user U as well. Note that the body position and change period are examples of biometric information.

Any sensor can be used for the first acquisition unit 41 as long as it is possible to specify the body position and the change period. For example, a radio wave sensor, an acceleration sensor, or an optical sensor may be used as the first acquisition unit 41 . The first acquisition section 41 continuously generates the detection signal V1. That is, the change over time of the load of the user U is detected.

The second acquisition unit 42 is a sensor that generates a detection signal V2 representing the body temperature of the user U. The detection signal V2 is used to identify the body temperature of the user U (an example of biological information). For example, any known body temperature sensor (such as an infrared sensor) is used as the second acquisition unit 42 . The second acquisition unit 42 is attached (attached) to, for example, body surfaces of a plurality of parts of the body of the user U (torso, hands, feet, head, neck, etc.). A non-contact body temperature sensor may be used as the second acquisition unit 42 as long as the detection signal V2 representing the body temperature of the user U can be generated. The second acquisition section 42 continuously generates the detection signal V2.

The third acquisition unit 43 is a sensor that generates a detection signal V3 representing the humidity of the user's U body surface. The detection signal V3 is used to specify the humidity of the user's U body surface (an example of biological information). For example, any known humidity sensor is used as the third acquisition unit 43 . The third acquisition unit 43 is attached at the same position as the second acquisition unit 42 on the body surface of the user U, for example. A non-contact humidity sensor may be used as the third acquisition unit 43 as long as it can generate the detection signal V3 representing the humidity of the user's U body surface. Alternatively, a device in which the second acquisition unit 42 and the third acquisition unit 43 are integrated may be used. The second acquisition section 42 continuously generates the detection signal V2. Moreover, the numbers of the second acquisition unit 42 and the third acquisition unit 43 are arbitrary.

<Auxiliary Mechanism 21>
The assist mechanism 21 is a mechanism for assisting the change of the body position of the user U lying on the mattress 20A (typically, the user U turns over during sleep). Specifically, the assist mechanism 21 includes a plurality of column members 211 . Each column member 211 is a columnar member elongated along the Z direction (the thickness direction of the mattress 20A). A plurality of column members 211 are closely arranged so as to be parallel to each other. A plurality of pillar members 211 are arranged so that it may cover the whole mattress 20A in plane view.

As illustrated in FIG. 9, the column member 211 is, for example, a regular hexagonal column. The diameter of the column member 211 (the length of the diagonal line of the regular hexagon) is, for example, 20-40 mm. Note that the column member 211 is not limited to a regular hexagonal column. For example, a polygonal prism (for example, a square prism) other than a cylinder or a regular hexagonal prism may be used as the column member 211 . The column member 211 of the third embodiment is hollow. It can also be said that the column member 211 is tubular. That is, a through hole is formed in the column member 211 along the Z direction.

The plurality of column members 211 are individually movable along the Z direction. Specifically, each column member 211 is movable within a predetermined range from a predetermined position (initial position) to the positive side and negative side (vertical direction) in the Z direction. Each column member 211 is movable so that the posture of the user U is changed. Arbitrary various actuators are appropriately used for movement of each column member 211 . In addition, the column member 211 is made of any material that can be lightened and has durability.

The movement of each column member 211 of the auxiliary mechanism 21 is controlled according to biological information. In the third embodiment, the movement of the column member 211 is controlled according to the body position and change period. That is, in the third embodiment, the auxiliary mechanism 21 is controlled according to two pieces of biometric information. Note that the change in body position is typically rolling over.

<Temperature Mechanism 22>
The temperature mechanism 22 is a mechanism for adjusting the temperature of the mattress 20A. Therefore, it is possible to adjust the body temperature of the user U. For example, the temperature mechanism 22 includes a liquid whose temperature can be changed (hereinafter referred to as “adjustment liquid”) and an adjustment device 213 . The entire interior of the container K is filled with the adjustment liquid. For example, the gap between the column members 211 and the column members 211, the inside of the column members 211, and the upper and lower portions of the column members 211 are filled with the adjustment liquid. The mode of filling the container K with the adjustment liquid is arbitrary. For example, the container K contains a tube filled with the adjustment liquid, a bag made of resin, or the like.

The adjustment device 213 includes a temperature adjustment section (not shown) and a circulation section (not shown). For example, the adjusting device 213 is positioned below the column member 211 (on the positive side in the Z direction). The temperature adjuster is a device capable of changing (cooling or heating) the temperature of the adjustment liquid. For example, a plurality of Peltier elements capable of cooling the adjustment liquid and a heater capable of heating the adjustment liquid constitute the temperature adjustment section. Then, the temperature of the adjustment liquid is changed by indirectly contacting the adjustment liquid with the temperature adjustment unit. The circulation unit (for example, a pump) is a device that circulates the adjustment liquid so as to circulate inside the container K. As shown in FIG. The temperature mechanism 22 is preferably configured to be able to adjust the temperature for each of a plurality of areas corresponding to a plurality of body parts (trunk, limbs, neck, head) of the user U in the mattress 20A. In addition, as long as it is possible to adjust the temperature of the mattress 20A, the specific configuration of the temperature mechanism 22 is arbitrary.

The temperature mechanism 22 is controlled according to biological information. In 3rd Embodiment, the temperature mechanism 22 is controlled according to the user's U body temperature. Note that a portion of the temperature mechanism 22 (eg, the adjustment device 213) may be provided outside the mattress 20A.

<Humidity Mechanism 23>
The humidity mechanism 23 is a mechanism for moisture absorption or humidification. Specifically, the humidity mechanism 23 is composed of a plurality of air blowers (for example, compressors or fans) capable of blowing out air whose humidity has been adjusted (dehumidified or humidified). The humidity mechanism 23 is installed at an arbitrary position inside the container K. As shown in FIG. For example, the air blower is installed at a position where the blown air hits the user U from the contact surface. Therefore, it is possible to adjust the humidity of the body surface of the user U by blowing air from the humidity mechanism 23 . The humidity mechanism 23 preferably has a configuration capable of adjusting the humidity for each of a plurality of parts of the user's U body in the mattress 20A. In addition, as long as it is possible to adjust the humidity of the mattress 20A, the specific configuration of the humidity mechanism 23 is arbitrary.

The humidity mechanism 23 is controlled according to biological information. In 3rd Embodiment, the humidity mechanism 23 is controlled according to the humidity of the user's U body surface. A part of the humidity mechanism 23 may be provided outside the mattress 20A.

<Processing device 30>
The processing device 30 in FIG. 12 is a device that controls the auxiliary mechanism 21, the temperature mechanism 22, and the humidity mechanism 23. As shown in FIG. The processing device 30 of the third embodiment is realized by a computer system comprising a control device 31 and a storage device 32. FIG. For example, an information terminal such as a personal computer or tablet is used as the processing device 30 .

The control device 31 is composed of one or more processing circuits such as a CPU (Central Processing Unit), and controls each element of the processing device 30 in an integrated manner. The storage device 32 is, for example, one or more memories configured with known recording media such as magnetic recording media or semiconductor recording media, and stores programs executed by the control device 31 and various data used by the control device 31. Remember. As illustrated in FIG. 12 , the control device 31 of the third embodiment functions as a determination section 311 , a first control section 321 , a second control section 322 and a third control section 323 .

The determination unit 311 determines whether or not the change period exceeds a predetermined threshold value Z. That is, it is determined whether or not a predetermined period (threshold value Z) has passed since the user U changed the body position (turned over) by saving money. Note that the change period is specified from the detection signal V1 generated by the first acquisition unit 41 .

The first control unit 321 controls the movement of each column member 211 in the auxiliary mechanism 21 according to the biological information (change period and body position). Specifically, the timing at which each column member 211 moves and the position at which each column member 211 moves are controlled according to biological information.

First, the first control unit 321 controls the timing of movement of each column member 211 according to the change period. Specifically, the first control unit 321 moves each column member 211 when the determination unit 311 determines that the change period exceeds the threshold value Z. FIG. That is, each column member 211 moves (the user U's posture is changed) when the posture is not changed for a predetermined period of time. Note that the threshold Z is set to, for example, 20 to 30 minutes from the viewpoint that it is effective to turn over about every 30 minutes to prevent snoring, sleep apnea, congestion, muscle stiffness, and the like.

Second, the first control unit 321 controls the position to which each column member 211 moves according to the body position. A body position is estimated according to the detection signal V1 which the 1st acquisition part 41 produces|generates. The body position is, for example, the position of the user U's body axis. Specifically, the first control unit 321 controls the position of each pillar member 211 so as to roll over to a position different from the current body position.

An example of movement of the plurality of column members 211 in the auxiliary mechanism 21 will be described below. 13 to 16 are explanatory diagrams explaining an example of movement of the column member 211 when viewed from the Y direction. 13 to 16, the state of the column member 211 when the user U changes the body position from the supine position to the lateral position (turns over) will be described.

As exemplified in FIGS. 13 to 16, the movement of the column member 211 is controlled so as to transition, for example, state A1→state A2→state A3→state A4. As a result, the user U changes the body position from the supine position to the lateral position (turns over). The body position is identified continuously from state A1 to state A4. Movement of the column member 211 from the state A1 to the state A4 is performed by specifying the body position.

Schematically, one or more of the plurality of column members 211 corresponding to one of the left and right sides of the user U when viewed from the Y direction (the end on the positive side in the Z direction) is lowered. Then, the user U is made to turn over.

State A1 in FIG. 13 is the state of the column member 211 when the user U is in the supine position. As illustrated in FIG. 13, in state A1, for example, the positions in the Z direction of the tips of all the column members 211 are the same. FIG. 13 exemplifies a state A1 in which the positions in the Z direction of the tips of all the column members 211 are the same. However, in the state A1, for example, the tips of the column members 211 may be located at different positions depending on the body of the user U so as not to burden the body.

In the state A2 of FIG. 14, one or more columns corresponding to a predetermined width (length in the X direction) on both left and right sides (negative side and positive side in the X direction) of the body position of the user U among the plurality of column members 211 The column member 211 is lowered (moved to the negative side in the Z direction). As illustrated in FIG. 14, for example, the column member 211 is moved so as to be inclined from the body position side to the positive side end and the negative side end in the X direction. Among the plurality of column members 211, the column members 211 positioned at the positive and negative ends in the X direction are lowered by, for example, about 50 mm at their tips compared to the column members 211 corresponding to the body position. Note that when the determining unit 311 determines that the change period exceeds the threshold value Z in the state A1, an operation is performed to move the plurality of column members 211 from the state A2 to the state A4.

In state A3 of FIG. 15, one or more column members 211 located on either the left or right side of the user U among the plurality of column members 211 are further lowered. Specifically, after the state A2 is set, the column member 211 on the side where the user U voluntarily moved is further lowered. FIG. 15 illustrates a case where one or more column members 211 located on the right side (positive side in the X direction) of the user U are further lowered from the state A2. For example, the end on the positive side in the X direction is lowered by about 50 mm from state A2.

As illustrated in FIG. 15, the column member 211 may be moved so that the position corresponding to the right shoulder of the user U is the lowest. On the other hand, one or more column members 211 located on the left side of the user U (negative side in the X direction) are raised (for example, raised by about 100 mm) from the state A2. As long as the end on the positive side in the X direction is within 60 mm from the state A2, the distance to be lowered is arbitrary. Similarly, as long as the end on the positive side in the X direction is within 60 mm from state A2, the distance to be raised is arbitrary.

In state A4 of FIG. 16, one or more column members 211 located on the right side of user U are further lowered from state A3, and one or more column members 211 located on the left side of user U are further raised. . For example, in state A4, the one or more column members 211 located on the right side of the user U are lowered by about 60 to 100 mm from the state A1, and the one or more column members 211 located on the left side of the user U are lowered. It rises about 60-100mm. That is, a height difference of about 120 to 200 mm is generated between the plurality of column members 211 .

As a result of the movement from state A1 to state A4, one or more column members 211 on either the left or right side (the right side in the third embodiment) of the user U as viewed from the Y direction among the plurality of column members 211 descends. Then, one or more column members 211 on the other side (the left side in the third embodiment) move upward. That is, among the plurality of column members 211, the slope from one side of the user U to the other side as viewed in the Y direction is made gentle. Since the body position of the user U is changed according to the movement of the plurality of pillar members 211, it is possible to change the body position (roll over) from the supine position to the side lying position.

One or more column members 211 on the side to be lowered (left side or right side) among the plurality of column members 211 have a width (about 400 mm) exceeding the shoulder width on the side to be lowered when viewed from the Y direction. lower. On the other hand, it is preferable that the width (the length in the X direction) of the side of the plurality of column members 211 to be raised as viewed in the Y direction is as small as possible.

Note that the specific example of the movement of the column member 211 when changing the body position of the user U from the supine position to the side-lying position is not limited to the above. If it is possible for the user U to turn over by lowering the tip of one or more of the column members 211 on either the left or right side of the user U as viewed from the Y direction, the column The method of moving the member 211 is arbitrary.

Also, in the third embodiment, the case where the body position of the user U is changed from the supine position to the side-lying position is exemplified, but the change in body position is not limited to the above exemplification. For example, the column member 211 may be moved so that the user U changes from the supine position to the side lying position, or the column member 211 may be moved so as to change from one supine position to the other supine position. .

The second control unit 322 controls the temperature mechanism 22 according to the user's U body temperature (biological information). An example of a method for controlling the temperature mechanism 22 by the second controller 322 will be described below, but the method for controlling the temperature mechanism 22 is not limited to the above example.

The second control unit 322 controls the temperature mechanism 22 so that the body temperature of each part of the body (trunk, extremities, neck and head) is maintained at a target body temperature (hereinafter referred to as “target body temperature”). Control. The body temperature of each part of the body is specified from the detection signal V2 acquired by the second acquisition unit 42 . For example, when there is no lesion such as inflammation in each part of the body, the second control unit 322 controls the temperature mechanism so that the target body temperature of the trunk and extremities is 26.0°C, the neck is 25.0°C, and the head is 18.0°C. After controlling 22, the temperature mechanism 22 is controlled so that the target body temperature of each part rises (+0.25 to 0.5°C/hour) over time. However, it is not essential to control the temperature mechanism 22 so that the target body temperature changes over time. When the body temperature specified by the detection signal V2 is lower than the target body temperature, the temperature of the adjustment liquid in the temperature mechanism 22 is controlled to be higher, and when the body temperature specified by the detection signal V2 is higher than the target body temperature is controlled so that the temperature of the adjustment liquid in the temperature mechanism 22 is lowered.

The third control unit 323 controls the humidity mechanism 23 according to the humidity of the user's U body surface. An example of a method for controlling the humidity mechanism 23 by the third control section 323 will be described below, but the method for controlling the humidity mechanism 23 is not limited to the above example.

The third control unit 323, for example, controls the temperature so that the body surface humidity of each part of the body (trunk, limbs, neck, and head) is maintained at a target humidity (hereinafter referred to as “target humidity”). Control mechanism 22 . The humidity of each part of the body is specified from the detection signal V3 acquired by the third acquiring section 43. FIG. For example, when there is no lesion such as inflammation in each part of the body, the third control unit 323 controls the humidity mechanism 23 so that the target humidity of each part of the body is 50% or less. When the body surface humidity specified by the detection signal V3 is lower than the target humidity, the humidity mechanism 23 is controlled to blow humid air, and the humidity specified by the detection signal V3 is higher than the target humidity. In that case, the humidity mechanism 23 is controlled to blow dry air.

The method of setting the target body temperature and target humidity is arbitrary. For example, the user U may set the target body temperature and target humidity for each part by himself/herself through an input device (not shown) of the processing device 30 . Also, the target body temperature and the target humidity may be changed over time, for example.

As can be understood from the above description, each of the plurality of column members 211 moves individually in the third embodiment, so it is possible to move the mattress 20A for each region corresponding to each column member 211. That is, the mattress 20A can be moved in units of subdivided areas. Therefore, it is possible to appropriately assist the sleeping user U in changing his or her posture. As a result, it is possible to change the body position without making the user U assume an unreasonable posture.

In the bedding system 100 of the third embodiment, movement of the plurality of column members 211 is controlled by biometric information, so that it is possible to assist the user U in changing his or her posture. That is, optimized sleep for each user U can be provided.

In the third embodiment, the movements of the plurality of column members 211 are controlled according to the body position and the change period, so that it is possible to assist each user in changing the optimal body position individually.

Moreover, since the temperature mechanism 22 and the humidity mechanism 23 are built in the mattress 20A, even if it is difficult to maintain the indoor temperature and humidity properly, the body temperature and humidity of the user U can be properly maintained. is possible. In other words, while adjusting the temperature and humidity, it is possible to appropriately assist the sleeping user in changing his/her body position at any time. As understood from the above description, according to the bedding system 100 of the third embodiment, it is possible to provide the user with a comfortable sleep.

<Fourth Embodiment>
A fourth embodiment of the present invention will be described. In addition, in each embodiment illustrated below, the reference numerals used in the description of the third embodiment are used for the elements whose action or function is the same as that of the third embodiment, and the detailed description of each element is appropriately omitted.

In the bedding system 100 according to the fourth embodiment, the pillow 20B is exemplified as bedding. Other components are the same as those of the third embodiment, except that the type of bedding is different. FIG. 17 is a plan view of bedding according to the fourth embodiment. The bedding system 100 according to the fourth embodiment also includes bedding, an auxiliary mechanism 21, a temperature mechanism 22, a humidity mechanism 23, a processing device 30, and a sensor unit 40, similarly to the third embodiment. FIG. 18 is a side view of the pillow 20B (a side view when viewed from the positive side in the X direction). The pillow 20B also has a container K in the same manner as the mattress 20A. The container K includes a surface (contact surface F) on which the head of the user U rests when lying down.

As illustrated in FIG. 18, similarly to the third embodiment, an auxiliary mechanism 21, a temperature mechanism 22 and a humidity mechanism 23 are installed inside the pillow 20B. The auxiliary mechanism 21 according to the third embodiment includes a plurality of column members 211, like the third embodiment. In addition, in the fourth embodiment, the diameter of the column member 211 (the length of the diagonal line of the regular hexagon) is, for example, 10 to 20 mm.

The temperature mechanism 22 of the fourth embodiment is a mechanism for adjusting the temperature of the pillow 20B. Therefore, it is possible to tune the temperature at the user U's head. For example, the temperature mechanism 22 includes the adjustment liquid and the adjustment device 213, as in the third embodiment. The entire interior of the container K in the pillow 20B is filled. For example, the gap between the column members 211 and the column members 211, the inside of the column members 211, and the upper and lower portions of the column members 211 are filled with the adjustment liquid. In order to move the upper surface of the column member 211 up and down (in and out) according to the shape of the surface of each part of the body, and to support the center of gravity and the weight load of each part of the body, the buoyancy as large as possible is required. A liquid with a large specific gravity is employed as the conditioning liquid as practicable. It is preferable that the temperature mechanism 22 can adjust the temperature for each of a plurality of regions corresponding to a plurality of regions of the head of the user U in the pillow 20B.

Also in the fourth embodiment, for example, the gaps between the column members 211 are filled with the adjustment liquid. Therefore, as illustrated in FIG. 18, the position of the tip of each column member 211 conforms to the shape of the body surface according to the difference in the distribution of the body weight due to the buoyancy of the adjustment liquid. As described above, each column member 211 moves under the control of the first control unit 321 and also moves according to the user's U load. A similar configuration can also be employed in the third embodiment.

The humidity mechanism 23 is a mechanism for absorbing or humidifying, as in the third embodiment. The humidity mechanism 23 is installed at an arbitrary position inside the container K in the pillow 20B. The humidity mechanism 23 is composed of a plurality of air blowers (for example, compressors and fans) capable of sending out temperature- and humidity-controlled air. For example, the blower is installed at a position where the blown air hits the user's U head (especially neck) from the contact surface. Therefore, it is possible to adjust the humidity of the user U's head by blowing air from the humidity mechanism 23 .

A sensor unit 40 of the fourth embodiment includes a first acquisition section 41, a second acquisition section 42, and a third acquisition section 43, as in the third embodiment.

The first acquisition unit 41 is a sensor used to identify the body position and change period, as in the third embodiment. In addition, the body position of 4th Embodiment is a position of the user's U head (for example, center of gravity) in a contact surface.

The first acquisition unit 41 generates a detection signal S1 that is displaced on the contact surface F according to the load on the head of the user U, as in the third embodiment. The detection signal S1 is used to identify the body position and the change period as in the third embodiment. For example, a plurality of first obtaining portions 41 are provided at predetermined intervals in the area on the contact surface F side inside the pillow 20B (container K).

The second acquisition unit 42 is a sensor that generates a detection signal S2 representing the body temperature of the user U, as in the third embodiment. The second acquisition unit 42 is attached (attached) to a plurality of locations on the head or neck of the user U, for example.

The third acquisition unit 43 is a sensor that generates a detection signal S3 representing the humidity of the body surface of the user U, as in the third embodiment. The third acquisition unit 43 is attached at the same position as the second acquisition unit 42 on the body surface of the user U, for example.

As in the third embodiment, the first control unit 321 controls movement of each column member 211 in the auxiliary mechanism 21 according to the change period and body position. First, the first control unit 321 controls the timing at which each column member 211 moves according to the change period. Specifically, the first control unit 321 moves each column member 211 when the determination unit 311 determines that the change period exceeds the threshold value Z. FIG. Secondly, the first controller 321 controls the position to which each column member 211 moves according to the body position.

The second control unit 322 controls the temperature mechanism 22 according to the body temperature (biological information) of the user U, as in the third embodiment. The 3rd control part 323 controls the humidity mechanism 23 according to the humidity of the body surface in the user's U head like 3rd Embodiment.

An example of movement of the plurality of column members 211 in the auxiliary mechanism 21 according to the fourth embodiment will be described below. 19 to 22 are explanatory diagrams explaining an example of movement of the column member 211 when viewed from the Y direction. FIG. 19 to FIG. 22 describe the state of the column member 211 when the user U changes the body position from the supine position to the lateral position (turns over).

As exemplified in FIGS. 19 to 22, the movement of the column member 211 is controlled so as to transition, for example, state B1→state B2→state B3→state B4. As a result, the user U changes the body position from the supine position to the lateral position (turns over). The body position is identified continuously from state B1 to state B4. Movement of the column member 211 from the state B1 to the state B4 is performed by specifying the body position. The states B1 to B4 correspond to the states A1 to A4 in the third embodiment.

Schematically, by lowering the tip (the end on the positive side in the Z direction) of one or more of the plurality of column members 211 on either the left or right side of the user U when viewed from the Y direction, The user U is made to roll over.

State B1 in FIG. 19 is the state of the column member 211 when the user U is in the supine position. In the state B2 of FIG. 20, one or more column members 211 corresponding to a predetermined width on both left and right sides (negative side and positive side in the X direction) of the head of the user U among the plurality of column members 211 are lowered ( move to the negative side in the Z direction). As illustrated in FIG. 20, for example, the column member 211 is moved so as to be inclined from the body position side to the positive side end and the negative side end in the X direction. Of the plurality of column members 211, the column members 211 positioned at the positive and negative ends in the X direction are lowered by, for example, about 15 mm at their tips compared to the column members 211 corresponding to the body position. Note that when the determining unit 311 determines that the change period exceeds the threshold value Z in the state B1, an operation is performed to move the plurality of column members 211 from the state B2 to the state B4.

In state B3 of FIG. 21, one or more column members 211 corresponding to a predetermined width located on either the left or right side of the head of the user U among the plurality of column members 211 are further lowered. Specifically, after the state B2 is set, the column member 211 on the side where the head of the user U has voluntarily moved is further lowered. FIG. 22 illustrates a case where one or more column members 211 located on the right side (positive side in the X direction) of the head are further lowered from the state B2. For example, the positive end in the X direction is lowered by about 15 mm from the state B2.

On the other hand, one or more column members 211 corresponding to a predetermined width located on the left side of the user U (negative side in the X direction) are raised (for example, raised by about 15 mm) from the state B2. As long as the end on the positive side in the X direction is within 15 mm from the state B2, the distance to be lowered is arbitrary. Similarly, as long as the positive end in the X direction is within 15 mm from state B2, the distance to be raised is arbitrary.

In the state B4 of FIG. 22, the one or more column members 211 located on the right side of the user U's head are further lowered from the state B3, and the one or more column members 211 located on the left side of the user U are lowered. raise it further. For example, in state B4, the one or more column members 211 located on the right side of the user U are lowered by about 30 to 60 mm from the state B1, and the one or more column members 211 located on the left side of the user U are lowered. It rises about 30-60mm. That is, a height difference of about 60 to 120 mm is generated between the plurality of column members 211 .

As a result of the movement from state A1 to state A4, one or more column members 211 on either the left or right side (the right side in the third embodiment) of the user U as viewed from the Y direction among the plurality of column members 211 descends. Then, one or more column members 211 on the other side (the left side in the third embodiment) move upward. That is, among the plurality of column members 211, the slope from one side of the user U to the other side as viewed in the Y direction is made gentle. Since the body position of the user U is changed according to the movement of the plurality of pillar members 211, it is possible to change the body position (roll over) from the supine position to the side lying position.

<Modified example according to the third embodiment and the fourth embodiment>
The third and fourth embodiments illustrated above can be modified in various ways. Specific modification modes are exemplified below. It is also possible to appropriately combine two or more aspects arbitrarily selected from the following examples.

(1) In the third and fourth embodiments, the change period was used to control the timing of moving the pillar member 211. However, the biometric information used to control the timing of moving the pillar member 211 is as illustrated above. Not limited. For example, the following various types of information are used to control the timing of moving the column member 211 .

[Information about snoring]
The information about snoring is, for example, the volume of user U's snoring. The first acquisition unit 41 (for example, a microphone) picks up the snoring of the user U and generates a detection signal S1 corresponding to the sound. The determination unit 311 identifies the volume of snoring represented by the detection signal S1, and compares the volume with a predetermined threshold. The first control unit 321 moves the column member 211 when the determination unit 311 determines that the volume of snoring exceeds a predetermined threshold. Information about snoring is not limited to the volume of snoring. For example, the frequency of snoring may be used as information about snoring.

[Information on breathing]
The information about respiration is the respiration rate of the user U, for example. The first acquisition unit 41 is an arbitrary sensor capable of detecting the breathing of the user U, and generates a detection signal S1 representing the breathing of the user U. The determination unit 311 identifies the respiratory rate in a predetermined period from the detection signal S1, and compares the respiratory rate with a predetermined threshold. The first control unit 321 moves the column member 211 when the determining unit 311 determines that the respiratory rate is below a predetermined threshold.

Also, the period of apnea may be used as information about respiration. The determination unit 311 identifies an apnea period from the detection signal S1, and compares the period with a predetermined threshold. The 1st control part 321 moves the column member 211, when the determination part 311 determines that the said period exceeds a predetermined threshold value. Note that information about respiration is not limited to respiration rate and duration of apnea.

[Information about heartbeat]
The heartbeat information is, for example, the heartbeat rate of the user U. The first acquisition unit 41 is an arbitrary sensor capable of detecting the heart rate of the user U, and generates a detection signal S1 representing the heart rate of the user U. The determination unit 311 identifies the heart rate in a predetermined period from the detection signal S1, and compares the heart rate with a predetermined threshold. The first control unit 321 moves the column member 211 when the determination unit 311 determines that the respiratory rate exceeds (or falls below) a predetermined threshold.

Also, the occurrence of arrhythmia may be used as information related to heartbeat. The BR>B determination unit 311 detects the occurrence of arrhythmia from the detection signal S1. The first control unit 321 moves the column member 211 when the determination unit 311 detects arrhythmia.

As can be understood from the above description, the biological information used for controlling the timing of moving the column member 211 is arbitrary. The biological information used for controlling the timing of moving the column member 211 is not limited to the above examples. For example, various types of information such as body temperature, body motion, and body surface humidity are examples of biological information used to control the timing of moving the column member 211 . It should be noted that a combination of multiple types of biometric information may be used to control the timing of moving the column member 211 .

(2) The biological information used to control the position to which each column member 211 moves is not limited to the body position. For example, various types of information such as body temperature, body motion, and body surface humidity are examples of biological information used for controlling the position to which the column member 211 moves. It should be noted that a plurality of types of biometric information may be combined and used to control the position to which the column member 211 moves. As can be understood from the above description, biometric information is a general term for information used to control the assist mechanism 21 . Note that a sensor corresponding to the type of biological information is appropriately adopted for the first acquisition unit 41 .

(3) The biological information used for controlling the temperature mechanism 22 is not limited to the body temperature of the user U. For example, various other biological information may be used to control the temperature mechanism 22 . Similarly, the biological information used for controlling the humidity mechanism 23 is not limited to the humidity of the user's U body surface.

(4) In the third embodiment and the fourth embodiment, for example, a configuration is adopted in which the user U evaluates the degree of comfortable sleep (e.g., 10-grade evaluation) when waking up after sleeping using the bedding system 100 . The user U inputs the evaluation using an input device. Then, the second control unit 322 may set the target body temperature in consideration of the evaluation by the user U. Similarly, the third control unit 323 may set the target humidity in consideration of the evaluation by the user U. That is, the second control section 322 and the third control section 323 may feedback-control the temperature mechanism 22 and the humidity mechanism 23 based on the evaluation by the user U.

In the above configuration, the second control unit 322 sets the target body temperature (the target temperature at which it can be estimated that the user U can sleep most comfortably) using a learned model that has learned the relationship between the degree of comfortable sleep and the target body temperature. may A trained model that has learned the relationship between the degree of good sleep, various other parameters (air temperature, body temperature, humidity, psychological state, bowel movement, urination, air pressure, season, etc.) and the target body temperature may be used. Similarly, the third control unit 323 may set the target humidity (the target humidity at which it can be estimated that the user U will be able to sleep most comfortably) using a learned model that has learned the relationship between the degree of comfortable sleep and the target humidity. good. A trained model that has learned the relationship between the degree of good sleep, various other parameters (air temperature, body temperature, humidity, psychological state, bowel movement, urination, air pressure, season, etc.) and the target humidity may be used.

A trained model is a statistically estimated model generated by machine learning. Various statistical estimation models such as decision trees or neural networks are preferably used as trained models. A trained model is realized by a combination of a program (for example, a program module constituting artificial intelligence software) that causes the control device 31 to execute an operation for generating output data from input data, and a plurality of coefficients applied to the operation. be. A plurality of coefficients are set by machine learning (especially deep learning) using a large amount of teacher data and stored in the storage device 32 .

For the user U who is using the bedding system 100 of the present invention for the first time, if there is no lesion in each part of the body such as inflammation or chronic fatigue, the target humidity is set to 50% or less (43% to 50%), and the body trunk is・Set the target temperature to 26.0°C for the extremities, 25.0°C for the neck, and 18.0°C for the head. Then, over time, the degree of comfortable sleep upon awakening when the humidity in each part of the body was kept at a target humidity of 50% or less and the target temperature was set to rise at a rate of 0.25 to 0.5°C/hour was used. Person U evaluates. As described above, a configuration for inputting an evaluation for each part of the body can also be adopted. However, it is not essential to control the humidity mechanism 23 and the temperature mechanism 22 for each part.

Further, the first control unit 321 may control the movement of the column member 211 of the auxiliary mechanism 21 in consideration of the evaluation by the user U. For example, the first control unit 321 controls the movement of the pillar member 211 using a learned model that has learned the relationship between the degree of good sleep and movement of the pillar member 211 (for example, timing and position of movement).

According to the configuration that controls the temperature mechanism 22 and the humidity mechanism 23 using the learned model, it is possible to individually optimize the target temperature and target humidity for each user U. As a result, it is possible to encourage the user U to have a comfortable sleep.

(5) In the third and fourth embodiments, the bedding system 100 may use the bedding in which the mattress 20A and the pillow 20B are integrated. Regarding the bedding in which the mat and pillow 20B are integrated, the components and the control method of the auxiliary mechanism 21, the temperature mechanism 22, and the humidity mechanism 23 are the same as those in the above-described third and fourth embodiments. .

(6) In the fourth embodiment, the bedding is portable (it can also be used with a storage battery). The material of the bedding container K is made washable. As for the size of the pillow 20B, several types are prepared, ranging from a large size to a small size that can be carried around. In the case of a single pillow 20B, the maximum length is about 700 to 900 mm from the top of the head to the bottom of the shoulder blade, and the width is also 700 to 900 mm. In such cases, the length should be about 250-350mm from the top of the head to the top of the neck, and the width should be about 450-600mm, which is greater than the width of the shoulders. The height is the width of the shoulders minus the center of the body axis (rotation) and the length from the center of the neck to the temporal region, in order to make it easier to roll over from the side lying position. width), and when rolling over from the supine position, the center of the body axis, the center of the head, and the occipital end should be slightly lower than when lying on the side. As mentioned above, as long as the overall weight is within the range that can be carried, a range is given according to the physique of the individual.

(7) In the third and fourth embodiments, the auxiliary mechanism 21, the temperature mechanism 22, and the humidity mechanism 23 are controlled in consideration of the weight, height, age, sex, medical history, etc. of the user U. good too.

(8) In the third and fourth embodiments, the first controller 321 may move the column member 211 at predetermined intervals according to biometric information.

(9) In the third and fourth embodiments, the material of the bedding (especially the container K) is preferably a hygroscopic material. Also pay particular attention to static electricity countermeasures.

(10) In the third and fourth embodiments, the method of controlling the auxiliary mechanism 21, the temperature mechanism 22, and the humidity mechanism 23 may be as follows.

<Mattress 20A>
The second control unit 322 is based on the knowledge that the coolness of the head due to a comfortable low temperature helps to lower the temperature of the brain, which is overheated during the day, and makes sleep more comfortable. The temperature mechanism 22 is controlled to 28°C, which is 7°C or less than the core body temperature, even in the morning when the body temperature rises toward waking up due to the urge to urinate or endocrine.

In addition, the time and content of meals, especially dinner, are closely related to comfortable sleep. In addition, sympathetic nervous excitement caused by drinking coffee after dinner, smoking, excessive water intake, or strenuous exercise may interfere with sleep, so caution is required. Recently, it is known that physiologically active polypeptides, including various hormone-like substances and neurotransmitters such as serotonin produced by the intestinal flora, which are said to number more than 100 trillion, interact with the central nervous system and the immune system inside and outside the intestinal tract. became. In addition, it has become clear that sleep and the intestinal environment (balance between intestinal flora and intestinal immunity) also exert a great influence on each other. Just as the intestinal microflora is dominated by so-called good bacteria, whether or not you are getting enough dietary fiber to feed them, the secretion of various hormones in relation to your body clock, meal times, and sleep time can help you sleep better. is important.

In other words, although it depends on the degree of obesity, the degree of visceral fat accumulation, the presence or absence of diaphragmatic elevation, hiatus hernia, etc., reflux esophagitis is very likely to occur if the time from dinner to falling asleep is as short as 1 to 2 hours. It is well known that sleep is disturbed by heartburn, coughing, etc. In addition, meals with a lot of meat and oil take longer to digest, requiring an interval of 3-4 hours. If it's mainly vegetables, the burden on the stomach is light, so it's possible to do it in 2-3 hours. Therefore, salads and soups are preferable for late-night dinners. Recently, the relationship between intestinal bacteria and sleep has been discussed, and a vegetable-centered meal containing sufficient dietary fiber is also better in relation to bowel movements.

From the above point of view, in order to prevent reflux esophagitis and to reduce the burden on the heart, raise the upper body part of the bedding about 10 to 20 degrees when you fall asleep, including turning over, etc., depending on the sleeping state. , the angle may be decreased 1 to 3 hours after falling asleep, and each column member 211 of the auxiliary mechanism 21 may be controlled so as to decrease to 0 to 5 degrees.

Also, the interval between bathing time and falling asleep time has a big meaning. That is, after bathing for about 5 to 10 minutes in a relaxing half-body bath at 39 to 40°C, it is desirable to go to bed after 1.5 hours, if possible, when the body temperature drops and drowsiness is likely to occur. Such daily contents also need to be input in order to achieve comfortable sleep. In addition, if it is difficult to adjust the room temperature, the initial set temperature of the part (adjustment liquid) of the temperature mechanism 22 corresponding to the upper body part is lowered more than usual, and the drowsiness increases. make it

In addition, we aim to completely eliminate the 2 to 5 awakenings in the middle of the day and early morning awakenings from 1 to 5 am, which most disturb the feeling of good sleep and cause depressed mood, especially during shift work or early morning awakening. Another important point is whether or not it is possible to fall asleep again when . Therefore, when the weight of the head or the weight load disappears, for example, for one minute or more, it is regarded as an awake state, and the state at the time of falling asleep is approached. That is, for example, in the case of 10 minutes or more, the target humidity of the target body temperature/humidity mechanism 23 of the temperature mechanism 22 is reset to the state at the time of falling asleep to facilitate resuming sleep. In addition, if falling asleep is not smooth, each time, set the starting temperature lower than the initial setting by 1-2°C, for example, 20-22°C for the head and neck, 22-24°C for the chest, The lower body is set at 24 to 26°C, and the target body temperature and target humidity are set to change over time until the scheduled wake-up time.

In order to wake up comfortably, the temperature of the temperature mechanism 22 is increased toward the scheduled wake-up time, and at the same time, the lighting device provided on the side of the bedding system 100 is brightened with the passage of time from 30 to 60 minutes before the wake-up. The light and sound of the indirect lighting that is going on will encourage you to wake up, and at the same time, the bedding system 100 has a function of an alarm clock with a sound that does not make you uncomfortable. Furthermore, when the user does not get up after the scheduled time (when the weight load on the bedding does not disappear), the vibrating device that increases with time is also activated to encourage the user to get up.

<Pillow 20B>
First of all, comfortable sleep is not only easy to fall asleep, but also whether you can secure a deep sleep ratio (NREMst3 ratio) of 20 to 25% or more, whether you can easily turn over, and whether you wake up naturally when you wake up. I have a feeling of recovery from fatigue, a feeling of good sleep, and a sense of fulfillment. There is also a big thing.

As can be understood from the above explanation, the target body temperature and target humidity are not always constant values, but may be changed over time or depending on various factors.

(11) Measures against microbial infectious diseases such as viruses, bacteria, and fungi are necessary, not limited to the new coronavirus. Therefore, the humidity mechanism 23 according to the modified example adopts a configuration related to infectious disease countermeasures. FIG. 24 is a configuration diagram of a humidity mechanism 23 according to a modification. As illustrated in FIG. 24, the humidity mechanism 23 includes a compressor, an ultraviolet irradiation device, a moisture absorption layer, and an activated carbon layer. Air delivered from the compressor is delivered to the bedding 20 (20A, 20B) through the tube. An ultraviolet irradiation device, a moisture absorption layer and an activated carbon layer are provided between the compressor and the bedding.

The air sent out from the compressor (for example, wind speed 0.05 to 0.1 m/sec) first passes through an ultraviolet irradiation device. The ultraviolet irradiation device includes, for example, a constant temperature bath and a UVC lamp (germicidal lamp). The tube is placed in a constant temperature bath set at a predetermined temperature (for example, 18° C. to 28° C. can be set in increments of 1° C.), and the tube is irradiated with a UVC lamp. For example, irradiation with a UVC lamp is performed for 10 seconds or more, which is sufficient to show a sufficient effect of killing microorganisms such as viruses and bacteria. In addition, the ultraviolet irradiation device can be set to a predetermined humidity (for example, 40% to 52% can be set in increments of 2%).

The air that has passed through the ultraviolet irradiation device is sent to the activated carbon layer after passing through a moisture absorbing layer (for example, silica gel) that can adjust the humidity. The activated carbon layer collects ozone generated in the ultraviolet irradiation device. Then, the air that has passed through the activated carbon layer is delivered to positions corresponding to each part of the bedding. Note that the moisture absorption layer is not essential.

Also, an ultraviolet irradiation device may be provided for each part of the body. The humidity mechanism 23 may be provided wholly inside the bedding, or may be partially provided outside the bedding. Although FIG. 24 illustrates a configuration in which the humidity adjusting device includes one ultraviolet irradiation device, the number of ultraviolet irradiation devices is arbitrary and can be changed as appropriate according to the length of the tube. From the viewpoint of obtaining a sufficient sterilization effect, regardless of the number of ultraviolet irradiation devices, a configuration that allows irradiation by the UVC lamp for 10 seconds or more as a whole is preferable.

It should be noted that the temperature and humidity in the humidity mechanism 23 are expected to change before reaching each part of the body. Therefore, the relationship between the temperature and humidity in the humidity mechanism 23 and the temperature and humidity in each part, including the outside temperature, humidity, weather, body temperature of the user, physical condition including inflammation of each part, etc. A learned model may be learned by machine learning for each wind speed. Then, the temperature and humidity in the humidity mechanism 23 may be set using the learned model.

Note that the above-described ultraviolet irradiation device, moisture absorption layer, and activated carbon layer may be provided in the temperature adjustment device 221 and the humidity adjustment device 222 installed in the shelter 200.

(12) In the bedding system 100 according to the third embodiment and the fourth embodiment, excessive movement of the external auxiliary mechanism 21 (column member 211) that blocks the person's spontaneous movement may interfere with good sleep. There is also a lot of sex. Therefore, first, for the purpose of exploring the spontaneous movement of the user U, such as the body axis, center of gravity, or breathing, set an arbitrary initial target temperature and target humidity, and after use 1 (normal) to 2 (shift work, etc.) In the case of ), in a flat state for a week, various parameters such as body weight, heart rate, breathing, snoring, body temperature changes, etc. are monitored over time. The sleeping phase, body movement, and temporal/physical or geographical changes in sleep phase, body movement, and rolling over are recorded and grasped as temporal changes on a three-dimensional coordinate axis, and utilized for conditions at the time of next use or realization of induced rolling over.

In addition, before use and during use 1 (normal) to 2 weeks (in the case of shift work, etc.), while checking the attached sound sleep checklist, feedback on the user's feeling of sleep, satisfaction, etc., and the target temperature・Set the target humidity over time to comfortable mode, monitor and record various parameters such as body weight, breathing, snoring, body temperature changes, etc. over time, and monitor and record the person's limbs, body movements, and tossing and turning. Temporal, physical, or geographical changes are recorded and grasped as temporal changes on a three-dimensional coordinate axis, and utilized for initial conditions at the time of full-scale use or for assisting changes in posture. As the good sleep checklist, for example, treatment may be changed in a plurality of stages as follows.
Score of 8 or less Score as is 9-14 Score adjustment by the person in charge of the device is required Score 15-20 Need instructions such as change of prescription from attending physician Score of 21 or more Need medical treatment by a sleep specialist or neuropsychiatrist

(13) In the third and fourth embodiments, the auxiliary mechanism 21, the humidity mechanism 23, and the temperature mechanism 22 may be controlled in consideration of the following various types of information during the explanation before use.

Family structure living together (including presence or absence of stress, nursing care status, etc.), height and weight (BMI), medical history (especially stroke, heart disease such as arrhythmia), complications (chronic tonsillitis, sinusitis, etc. related to the nose and mouth)・Current symptoms (including hypertension, diabetes, heart disease such as heart failure, cerebrovascular disease, asthma, emphysema, liver disease, depression, etc.) ・Family history, life history (sleep habits (posture during sleep, mainly supine position, right side lying position, left side lying position), sleep time (including naps and double naps)), bathing (including time, temperature, sauna, etc.), coffee (including time (daytime, after evening), amount, etc.) In addition, smoking (past smoking, current smoking/passive smoking)/drinking (frequency, amount, blush/no blush), allergy history (including hay fever/asthma), usual blood pressure/pulse Number, temperature, recent symptoms, usual meal times, meal content, whether or not you have snacks (content), work content (whether or not you are stressed (interpersonal relationships, etc.)), time period (including whether you work at night, shift work, etc.) , AHI value, etc. at the time of diagnosis of sleep apnea syndrome are input by the user U through the input device.

In addition, if possible, every day from dinner to before bedtime, ask them to enter their physical condition, stress at work, exercise time/content, meal time/content, alcohol consumption/amount, bathing time/content, etc. After waking up, the user U is similarly asked to input sleep time and details (including the number of times he wakes up and the number of times he goes to the toilet at night), physical condition at the time of waking up, symptoms such as a feeling of good sleep, headache, and dryness, and the state and malfunction of the equipment. .

In addition, we will be able to pursue better comfort by reviewing in units of 1 to 4 weeks or by comparing with the conventional average, previous week/period. In addition, items related to subjective symptoms include situations in which drowsiness occurs during the day (e.g., dozing off almost all the time, sitting and reading a newspaper or book, sitting and watching TV, during a meeting or at a movie theater). - sitting quietly in a theater, riding in a car driven by someone else for an hour straight, lying down to rest in the afternoon, sitting and chatting, eating lunch without drinking When the subject is sitting quietly, when the subject is driving, when the vehicle is stopped for several minutes due to a traffic jam, etc.), the subject is also asked to enter whether he or she has any of the following symptoms. Frequent snoring, waking up with difficulty breathing, waking up with the urge to urinate two or more times during the night, feeling a decline in memory and concentration, feeling fatigued and unable to get rid of fatigue, stopping breathing for several minutes during sleep from family members Apnea is pointed out, light sleep at night or waking up frequently, heavy head and headache when waking up or in the morning, chronic sleep deprivation without feeling of sound sleep when waking up, drinking alcohol every day instead of sleeping pills, etc. also enter.

(14) In the first embodiment and the second embodiment, when using the bedding system 100 according to the third embodiment or the fourth embodiment, the control of the temperature control unit 421 and the control of the second control unit 322 are interlocked with each other, and the control of the humidity control unit 422 and the control of the third control unit 323 are interlocked with each other.

　Feeling of good sleep is evaluated by a good sleep check, etc., but it is strictly subjective and is greatly affected by changes in daily physical and mental stress. Therefore, including the information that the user inputs into the tablet instead of the diary every day, feedback is provided by AI, and the output information is controlled and adjusted every time from the start of the shelter 200 or the bedding system 100 to the time of waking up, Achieve better sleep every day. Of course, adjustment is necessary for each change in season, climate, oxygen concentration, temperature, humidity, sound, vibration, smell, smoke, dust, etc., but giving a great sense of security even in the event of a natural disaster or fire leads to a good sleep. Therefore, even if you can evacuate at the shelter, if you need to escape without fail, you need a hatch or an emergency exit that can be opened and closed regardless of the large pressure difference (air pressure difference, pressure difference) between the room and the outside along with the door. Conceivable. It is also preferable to provide a space within the wall structure for storing supplies such as emergency food for several days and portable toilets.

As described above, the shelter 200 and the bedding system 100 may be used alone or in combination. When used together, each controller (421, 422, 423) in the shelter 200 and each controller (321, 322, 323) in the bedding system 100 individually perform control over time. That is, each control unit of the shelter 200 and each control unit of the bedding system 100 function as an integrated control device. On the other hand, when using the shelter 200 and the bedding system 100 alone, depending on the region, season, atmospheric pressure, climate, oxygen concentration, temperature, humidity, sound, vibration, smell, physical condition, mental state, etc. Control may be performed individually.

(15) If the space where the user U is located is tilted (for example, the floor is not horizontal, the floor is distorted, the pillars and walls are not vertical, or the pillars and walls are distorted) , it is conceivable that the autonomic nerves of the user U are significantly affected even if the user is only in the space for a short period of time. Therefore, if the shelter is tilted, the tilt of the shelter may be changed so that the floor is horizontal without distortion, and the pillars and walls are vertical without distortion. Whether or not the shelter is tilted is determined by a level or tilt sensor provided in the shelter 100 .
