Abstract

PROBLEM TO BE SOLVED: To effectively accelerate blood circulation particularly for the treatment and prevention of hemorrhoids. SOLUTION: A passage from a heating unit for heating wash water, and a passage from a cooling unit for cooling wash water, are periodically switched by a directional control valve to supply a nozzle alternately with warm water and cold water. The excitation pattern of a coil in an actuator built in a nozzle head is altered to change the moving range of a discharge hole to thereby change the washed area of human body private parts which the wash water discharged from the discharge hole reaches. The former hot-cold cycle (a) of the wash water and the cycle (b) of the latter discharge form change are synchronized keeping the specified relation to produce synergism of a hot-cold stimulus and a mechanical stimulus by the contact of discharge water. The relaxation and contraction of blood vessels are accelerated to acquire high blood circulation accelerating effect.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for cleaning a local part of a human body for cleaning a local part of a person using a toilet with water.

[0002]

2. Description of the Related Art Hemorrhoids are roughly classified into hemorrhoids known as wart hemorrhoids, anal fissures known as cut hemorrhoids, and anal fistulas. The most common of these is hemorrhoids, mainly due to congestion of the anus, and promotion of blood circulation is necessary for prevention and treatment.

[0003] In order to easily promote blood circulation in the vicinity of the anus at home, a human body configured to wash out dirt adhering to a local part of the human body by spraying washing water from a nozzle toward a local part of the human body. A local cleaning device is useful.
In general, in a human body local cleaning device, hot water at an appropriate temperature can be ejected from a nozzle. By applying such hot water to an affected part, a blood vessel is expanded and blood circulation is promoted. Of course, it can be expected that water discharge is applied to the affected area to stimulate blood vessels, and blood circulation is promoted by the same effect as massage.

In order to further promote blood circulation, it is effective to alternately apply hot water and cold water to the affected part alternately, instead of simply bringing hot water alone to the affected part. In other words, when cold water is applied to the affected area, the blood vessels temporarily contract, and then when hot water is applied to the affected area, the blood vessels expand suddenly due to the recoil, which greatly contributes to promoting blood circulation. There is also a secondary effect of strengthening the blood vessel wall by repeatedly contracting and expanding the blood vessel. In the following description, such an effect is collectively referred to as a “warming effect”.

[0005]

Some human body cleaning devices mainly intended to treat hemorrhoids by paying attention to such points have been known. For example, Japanese Patent Publication No. 4-10539 and Japanese Patent Laid-Open No. Hei 10-338960.
Japanese Patent Application Laid-Open Publication No. H11-157210 discloses a human body local cleaning device having a configuration in which hot water and cold water are alternately jetted at predetermined intervals from a nozzle toward a human body local portion. However, the mere alternate injection of washing water at high and low temperatures has a monotonous feeling,
In addition, the blood circulation promoting effect is not always high only by the warming / cooling effect.

Japanese Unexamined Patent Application Publication No. 11-309196 discloses a temperature control system in which relatively high temperature water and low temperature water are alternately jetted, and the temperature rises as time elapses as a whole. And a human body cleaning device for performing the same. According to this, although there is a certain effect that the monotonous feeling is reduced by a change in temperature, during cleaning,
Since almost the same water flow stimulus continues, the massage effect is poor and it is not enough to promote the contraction / relaxation of the blood vessels and obtain the blood circulation promoting effect. In addition, when the ambient temperature is high, such as in summer, the warm state temperature is strongly felt, causing discomfort, and conversely,
When the ambient temperature is low, such as in winter, there is a problem that a cold state temperature is strongly felt and discomfort is caused.

[0007] On the other hand, Japanese Patent Application Laid-Open No. 11-43977 discloses that when a blood flow increase cleaning different from the normal cleaning is specified, either the flow rate or the water temperature of the cleaning water injected toward the human body part is specified. A human body cleaning apparatus having a configuration in which both or both of them vary continuously with time (either periodically or aperiodically) is described. That is, by adding a fluctuation (fluctuation) in the flow rate to a fluctuation in temperature (fluctuation), an appropriate stimulus to the local area is aimed. However, since the fluctuation of the flow rate does not match the timing of the contraction / relaxation of the blood vessel due to the change in the water temperature, the massage effect that contributes to the promotion of blood circulation is poor.

[0008] That is, none of the conventional human body local cleaning devices have a sufficiently high blood circulation promoting effect. The present invention has been made in view of the above points, and its main purpose is to provide a relaxing effect for relaxing a user's feeling and a massage effect on blood vessels, and to provide high blood circulation without giving discomfort. It is an object of the present invention to obtain a human body local cleaning device which can obtain a promoting effect, and can exert a high effect in treating and preventing hemorrhoids and the like.

[0009]

Means for Solving the Problems, Embodiments of the Invention, and Effects A first human body cleaning apparatus according to the present invention, which has been made to solve at least a part of the above-mentioned problems, comprises a discharge device provided in a nozzle. A cleaning device for cleaning a local part of a human body by allowing cleaning water discharged from a water outlet to reach a local part of a human body; A) a temperature control means for controlling the water temperature adjusting means so as to change the temperature of the washing water at a predetermined cycle; and c) changing a form of water discharged from the water outlet at a cycle synchronized with a cycle of changing the temperature of the washing water. And water discharge form control means for causing water discharge.

In the first human body part cleaning apparatus, under the control of the temperature control means, the water temperature adjusting means adjusts the temperature of the cleaning water discharged from the water outlet and reaching the human body part at a predetermined cycle (hereinafter referred to as "hot / cold"). The heating and / or cooling is adjusted so as to fluctuate in a “period”. The water temperature adjusting means may be, for example, a means for heating and / or cooling the temperature of the discharged washing water almost in real time, or a washing method in which a plurality of systems generated by the heating and / or cooling means have different temperatures. A configuration in which the flow path of the water is switched, a configuration in which the water temperature is changed by changing a mixing ratio of the washing water from the plurality of flow paths, or the like may be employed. The water discharge form control means periodically changes the water discharge form of the wash water from the water discharge port (hereinafter, referred to as “water discharge form cycle”) in synchronization with such a fluctuation cycle of the water temperature. Various water discharge modes can be considered as the water discharge form that can be varied. For example, the flow rate, flow rate, pressure, space volume ratio (air mixing ratio) of the wash water, the wash area hit by the wash water, The distance, the angle at which the washing water reaches the local part of the human body, the size (particle size) of the water mass when the spouted washing water is composed of a mass of water, and the like. Any combination is acceptable.
In addition, in this specification, the thing that affects the tactile sensation according to the change in the form of water discharge is referred to as mechanical stimulation.

It is sufficient that the warming / cooling cycle and the water discharge form cycle are substantially synchronized, and in some cases the two cycles may be the same, but the ratio of the warming / cooling cycle and the water discharge form cycle is almost N: M (N, M Natural number)
It only needs to be defined as If N> M, the water discharge form cycle is shorter than the warm and cool cycle, so that the mechanical stimulus change for the user becomes strong, which is suitable for a person who likes a strong stimulus feeling. In addition, the monotonous feeling disappears particularly when the mechanical stimulus becomes strong. Conversely, if N <M, the water discharge mode cycle is longer than the warm / cool cycle, and the mechanical stimulus change for the user is weak. Therefore, it is suitable for a person who likes a moderate stimulus, such as a patient with severe hemorrhoids. In addition, a gentle change in mechanical stimulus can give the user a sense of relaxation. Furthermore, if M = N, both cycles are the same, so the form of water discharge between hot water discharge and cold water discharge is different, and the difference between the warm stimulus and the cold stimulus is remarkable, and a high massage effect is obtained. In addition, humans have a characteristic that it is difficult to feel a weak stimulus immediately after a strong stimulus. Utilizing this characteristic, by giving a mechanically strong stimulus before a relatively weak stimulus due to warming and cooling, it is possible to make the stimulus due to warming and cooling difficult to feel. That is, by using a mechanical stimulus, it is difficult for the user to feel a warm stimulus in summer and to feel a cold stimulus in winter, thereby eliminating the discomfort given to the user.

As described above, according to the first human body cleaning apparatus of the present invention, the mechanical stimulus and the warm / cold stimulus can be effectively performed without giving the user any discomfort, tension or monotonous sensation. A synergistic effect can be created to promote blood circulation in and around the user's anus. Therefore, it is extremely effective in treating and preventing hemorrhoids. Also, various stimulating feelings and comfortable feelings can be given according to the user's preference.

According to a second aspect of the present invention, there is provided a cleaning apparatus for cleaning a human body part according to the present invention, wherein cleaning water discharged from a spout provided in a nozzle reaches a human body part. And (b) a water discharge form control means for changing a form of water discharged from the water discharge port, and (b) a water temperature for heating and / or cooling the cleaning water discharged from the water discharge port. Adjusting means; and c) temperature control means for controlling the water temperature adjusting means to change the temperature of the washing water in a cycle synchronized with the change of the water discharge mode.

In the second human body part cleaning apparatus, the temperature control means, contrary to the first human body part cleaning apparatus, has a temporally changing water discharge mode, for example, the above-described flow rate of the cleaning water,
Flow rate, pressure, space volume ratio (air mixing ratio), washing area hit by washing water, distance from spout to human body part, angle when washing water reaches human body part, spouting washing water consists of water mass In accordance with at least one change in the size (particle size) of the water mass in such a case, the water temperature adjusting means is controlled so as to set the temperature of the washing water in synchronization with the change. At this time, an electrical control signal for changing the water discharge form may be received from the water discharge form control means, and the temperature of the washing water may be set in accordance with this signal. For example, means for detecting a change in the amount of water, a change in pressure, or the like may be separately provided, and the temperature of the washing water may be set according to the detection result. With such a configuration, the same effects as those of the first human body part cleaning device can be obtained.

According to a third aspect of the present invention, which is provided to solve at least a part of the above-described problems, the cleaning water discharged from a water discharge port provided in a nozzle reaches the human body local part. A human body local cleaning device for cleaning the local part by: a) human body information obtaining means for holding standard human body information of a human having a changing cycle, or detecting the human body information of a user of the device; b) water temperature adjusting means for heating and / or cooling the washing water discharged from the water outlet; c) controlling the water temperature adjusting means to change the temperature of the washing water in a cycle synchronized with the change cycle of the human body information. And temperature control means.

In the third apparatus for cleaning a human body part, the blood flow, the heart rate, and the like of a standard (ie, average) human or a user who uses the apparatus at that time are obtained by the human body information acquiring means. Temperature control means for acquiring human body information related to blood flow, such as blood pressure, pulse rate, and blood vessel contraction / relaxation cycle, or human body information that is a rhythm unique to the body such as respiration and affects the load on blood vessels; Controls the water temperature adjusting means in accordance with at least one change in the human body information so as to set the temperature of the wash water in synchronization with the change. For example, a sphygmomanometer, a blood flow meter, and the like can be used as means for acquiring the user's human body information. According to this configuration, the temperature of the washing water can be changed in accordance with, for example, the contraction / relaxation cycle of the blood vessels of the human body, so that a high blood circulation promoting effect can be obtained.

In particular, if the warming / cooling cycle is made smaller than the changing cycle of the human body information, the temperature change to the blood vessels becomes large and a great warming / cooling effect can be obtained, which is suitable for a person with low blood pressure or a relatively low heart rate. . It is also suitable for those who want an effect in a short time. Conversely, if the warming / cooling cycle is made longer than the change cycle of the human body information, the temperature change on the blood vessels will be smaller and the warming / cooling effect will be relatively low, so that a person with a heavy physical load such as high blood pressure or a high heart rate It is suitable for. According to this, a high relaxing effect is achieved. Furthermore, if the heating / cooling cycle is set to be substantially the same as the change cycle of the human body information, the most effective treatment can be performed in accordance with the physical fluctuation of the user.

Further, in the third human body local cleaning apparatus,
The temperature control means may be configured to change the set temperature on the high temperature side and / or the low temperature side according to the human body information. For example, when the user's blood pressure, heart rate, etc. are high, if the thermal stimulus is too strong, it may adversely affect the user's health condition. The range of change can be suppressed, and the warm / cool stimulus to the user can be reduced. Therefore, even a person suffering from hypertension or the like can use the human body local cleaning device with confidence.

Further, in the third human body local cleaning apparatus,
Similar to the first human body local cleaning apparatus, the apparatus may further include a water discharge mode control unit that changes a water discharge mode from the water discharge port at a cycle synchronized with a change cycle of the temperature of the wash water. According to this configuration, in addition to performing the thermal stimulus in a cycle synchronized with the change cycle of the human body information, the form of water discharge changes in a cycle synchronized with the stimulus, and a mechanical stimulus is applied to the local human body. Therefore, a massage effect is added, and blood circulation can be more effectively promoted.

The first, second, and third human body local cleaning devices according to the present invention having the above-described configuration can adopt the following various aspects.

That is, the water discharge form control means may include a predetermined trajectory water discharge control means for controlling a nozzle or a part of the nozzle so that the washing water discharged from the water discharge port draws a predetermined trajectory. it can. When the cleaning water discharged from the water discharge port is controlled by the predetermined trajectory water discharge control means to draw a predetermined trajectory, the position reached by the cleaning water changes with time. Thereby, for example, the washing area to be hit by the washing water can be changed, and a very narrow area centering on the anus and a wide area around the anus can be alternately stimulated. Since the central part of the anus is generally less painful, there is less pain compared to the peripheral part of the anus, and the irritation is weak when the former narrow area is exposed to washing water, and when the latter is applied to a wider area. Stimulation increases. Thereby, strength can be given to the stimulus.

Further, when the position to which the washing water is applied moves temporally, the washing water is intermittently applied when viewed at a certain position. Is not perceived by the user, and it feels as if the washing water is continuously applied. In this case, the stimulation becomes weak. Conversely, if the moving frequency of the predetermined trajectory is lowered, the stimulation becomes stronger. Thereby, strength can be given to the stimulus. Further, according to such a predetermined trajectory water discharge control means, since water discharge intermittently collides when viewed from a local portion of the human body local part, it is effective for water saving similarly to an intermittent pulsation water discharge control means described later. is there.

The predetermined trajectory water discharge control means can take various forms. In one embodiment, for example, the entire nozzle can be moved. Normally, in this type of human body local cleaning device, the nozzle is retracted to a retracted position (storage position) so as not to obstruct defecation, and only when a switch for instructing cleaning is operated, the nozzle is moved to the user's buttocks. It is moved to advance downward. Since the nozzle is provided with a nozzle drive mechanism for performing such advance and retreat, the entire nozzle is moved using the nozzle drive mechanism so that the cleaning water discharged from the water discharge port draws a predetermined trajectory. Can be For example, if the moving distance of the nozzle is increased, the washing area can be expanded and a strong stimulus can be given.On the contrary, if the moving distance of the nozzle is reduced, the spouting can be concentrated on a narrow washing area centered on the anus. Can be weakened. Further, if the moving speed is increased, the stimulation can be weakened for the above-mentioned reason. According to this configuration, although a mechanical power source is required, the mechanical power source and the drive mechanism required for the apparatus can be used in the first place, so that the increase in cost is extremely small.

In another embodiment of the above-mentioned predetermined trajectory water discharge control means, there is provided a moving body which moves on a predetermined trajectory without rotating around a predetermined axis, and the moving body is provided with the water discharge port. Consisting of: According to this configuration, since the moving portion is much smaller and lighter than when the entire nozzle is moved along a predetermined locus, it is easy to reduce the generation of vibration and noise due to driving. Also,
Since the moving speed of the predetermined trajectory can be increased, the water discharge form cycle can be set freely in a wider range. Also,
Since the responsiveness of the change in the water discharge form is good, synchronization with the heating / cooling cycle can be easily performed.

Another aspect of the water discharge mode control means may be an intermittent pulsation water discharge control means for intermittently or pulsatingly discharging the washing water from the water discharge port. The term “intermittent water discharge” as used herein means water discharge in which a period during which cleaning water is applied to a predetermined portion and a period during which cleaning water is not applied, or even if it is applied, are generated alternately. The pulsating spouting means a spouting in which the flow velocity, pressure, flow rate, etc. of the washing water hitting the local body part fluctuate with time.

In such intermittent (or pulsating) water discharge, if the flow velocity, pressure, flow rate, etc. partially increase over time,
It is easy to sense only the increased period. Therefore, even if the water discharge flow rate is reduced, if the flow rate is higher than that of the continuous flow during the increased period, for example, the stimulation is increased by intermittent (or pulsating) water discharge. Therefore, the change of the water discharge form can be switching between continuous water discharge and intermittent (or pulsating) water discharge. Also, if the intermittent pulsation cycle is lengthened,
The user easily perceives the discontinuity of the water mass, and feels a strong stimulus even at the same discharge pressure. Conversely, if the intermittent pulsation cycle is shortened, the user will not be able to sense the discontinuity of the water mass, but will perceive that the washing water is continuously applied, and the stimulus will be weakened. Therefore, the intensity of the stimulus can be temporally varied by appropriately varying the intermittent pulsation cycle. Furthermore, according to such intermittent pulsating spouting, even when the washing water flow rate is partially increased to enhance the stimulating feeling,
The discharge flow rate during a predetermined time can be reduced according to the wash water discharge time or the wash water discharge amount in one cycle period, which is also effective in saving water.

As specific examples of the intermittent pulsating water discharge control means, it is possible to use opening / closing and opening of a water pressure regulating valve, on / off of water pumping means such as a pump, and adjustment of operation strength. . In particular, if the electromagnetic coil system is used, by controlling the duty ratio of the ON time and the OFF time,
The pulsation can be generated in the washing water without time delay,
Further, the frequency can be easily increased.

In still another aspect of the water discharge mode control means, a swirl chamber for swirling the cleaning water discharged from the water discharge port is provided inside the nozzle, and the water discharge is performed according to the presence or absence of the swirl or the temporal change of the swirl amount. It is good also as composition which changes a form.

When the washing water turns toward the human body part while spiraling from the water discharge port, the washing water hitting the human body part hits obliquely when viewed instantaneously. As a result, the feeling becomes relatively soft, and the mechanical stimulation becomes weak. On the other hand, if the swirl is not added to the wash water to be discharged, the wash water flows almost linearly toward the human body part, and the relative stimulation is increased. Therefore, for example, by alternately performing with and without turning, it is possible to impart strength to the stimulus. In addition, when the swirling amount is increased, the state becomes almost a spray state, and the washing water becomes a water body having a small particle diameter, so that the irritation becomes extremely weak. Therefore, if the amount of turning is controlled, the intensity of the stimulus can be more precisely controlled.

As still another form of the water discharge form control means, the water discharge form control means includes an air mixing means for mixing air into the washing water discharged from the water discharge port,
A configuration in which the form of water discharge is changed by changing the amount of air to be mixed may be adopted.

When the amount of air to be mixed is relatively increased, the water flow becomes soft and the stimulus is weakened. Conversely, if the amount of air mixed in is relatively reduced, a strong stimulus is produced. The aeration means can take various forms, for example,
A method of sending air into water by a pump or a method of entraining air in washing water may be used. In particular, if an air pump is used, the amount of air mixed into the washing water can be easily controlled, and the intensity of the stimulus can be more precisely controlled. Further, according to such an air mixing means, the washing water is not continuously applied, and intermittent (or pulsating) water is discharged. Therefore, the water is effective for saving water as in the case of the intermittent pulsating water discharging control means.

Further, the water outlet comprises a plurality of water outlets, and the water discharge form control means determines the number and / or the total cross-sectional area of the water outlet from which the washing water is discharged, or the position of the water outlet. It is also possible to adopt a configuration in which the water discharge form is changed by changing the water discharge form.

According to this configuration, when flush water having the same flow rate is discharged from a large number of water discharge holes or water discharge holes having a large total cross-sectional area, the water discharge is dispersed and the stimulation is relatively weakened. Also, if water is intensively spouted at a specific part of the human body (excluding a part having almost no pain such as the central part of the anus), the relative stimulation is increased. Thereby, the intensity of mechanical stimulation can be given.

In general, hemorrhoid sufferers are often uncomfortable with a strong stimulus, but there is also a problem that the effect of promoting blood circulation is not sufficient unless a certain degree of stimulus is given.
Therefore, in the human body local cleaning device having each of the above-described configurations, at least at the beginning of the cleaning, the water discharge form and / or the temperature are set such that there is little irritation to the user, and in the subsequent period,
It is preferable to set the water discharge form and / or the temperature setting so as to give a stronger stimulus. In other words, at the beginning of the washing, the water discharge form and / or the temperature are set so as to be a relatively weak stimulus, and the stimulus is gradually or stepwise increased at a point when a certain time has passed and the water has acclimated. Good. In addition, the stimulus may be gradually increased with the lapse of time from the start of the cleaning. According to this configuration, since the stimulus is relatively weak at first, even if the patient suffers from hemorrhoids, etc., the stimulus can be strengthened to a certain extent at the time when he / she is accustomed, without having any discomfort or disgust. Also, the effect of promoting blood circulation can be achieved.

The form of water discharge and the temperature setting may be changed during cleaning. This change can be automatic,
It may be manually performed by the user.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a configuration diagram centering on the flow path of water of the human body local cleaning apparatus 1 according to the present embodiment.

As shown in FIG. 1, a water channel of the human body local cleaning device 1 is connected to an inlet valve unit 10, a heating unit 18 and a cooling unit 1 from an external water supply source (not shown).
9, flow control switching valves 20 and 21, and a flow path switching valve 22. The washing water is guided from the flow path switching valve 22 to the nozzle unit 30 via the bubble mixing unit 23 and the flow path switching valve 24, and is discharged from a water discharge hole formed in the nozzle body 31 of the nozzle unit 30 as described later. It is spouted.

The above configuration will be described in detail. Upstream water supply line 11 connected to an external water tap, which is a water supply source
Is connected to the water inlet 10a of the water inlet side valve unit 10. The washing water guided to the upstream water supply pipe 11 is
The suspended matter such as dust is removed by the strainer 12 and the check valve 1 is removed.
3. Flow into the constant flow valve 14. When the downstream electromagnetic valve 15 is opened, the cleaning water adjusted to a predetermined flow rate by the constant flow valve 14 flows in parallel into the heating unit 18 and the cooling unit 19 of the instant heating system. It is preferable that the flow rate of the cleaning water that flows in under such flow control is, for example, about 300 to 600 mL / min. In addition, upstream water supply line 1
1 may be branched from a flush water tank (not shown) for storing flush water for flushing a toilet and piped to the water inlet side valve unit 10.

Water inlet side valve unit 10 and heating unit 18
A drain line 17 with a relief valve 16 interposed is connected to a line connecting the cooling unit 19 and the cooling unit 19. If the pressure in the pipe upstream of the relief valve 16 rises abnormally for some reason, the relief valve 16 opens and the washing water is discharged to the outside through the drain pipe 17.

The heating unit 18 includes a heat exchange section 181 having a heater 182 built therein. A bimetal switch, a temperature fuse, and the like (not shown) for mechanically shutting off abnormal heating are provided in close contact with or close to the heater 182. In the heating unit 18, the temperature of the wash water flowing into the heat exchange unit 181 is detected by the incoming water temperature sensor 183, and the temperature of the wash water flowing out of the heat exchange unit 181 is detected by the output water temperature sensor 184. Is heated so that the washing water reaches the set temperature. Then, the flow of the warmed washing water is adjusted by a flow control switching valve 20 driven by a flow control motor or the like, and is sent to a flow path switching valve 22.

Further, the heat exchange section 181 is provided with a float switch 185 for detecting a water level inside the heat exchange section 181. The float switch 185 detects that the heater 182 is at or above a predetermined water level at which the heater 182 is submerged, and outputs a detection signal to the control unit 70 described later. Thus, the control unit 70 can supply power to the heater 182 only when the heater 182 is submerged, and can prevent so-called boil-off of the heater 182. Furthermore, the heating unit 18
Is provided with a vacuum breaker 186 at the washing water outlet from the heat exchange unit 181. This vacuum breaker 186
The heat exchanger 181 is introduced by introducing air into the pipeline.
The flow of the wash water in the downstream pipeline is shut off, and the flow control switching valve 20
Prevents backflow of wash water from the side.

On the other hand, the cooling unit 19 provided in parallel with the heating unit 18 is provided with a cooler 192 instead of the heater 182.
The heat exchange unit 191 has substantially the same configuration as that of the heating unit 18 except that the heating unit 18 is provided.
3, and based on the temperature detected by the water temperature sensor 194, the cooler 192 cools the washing water to the set temperature. Then, the flow rate of the cooled washing water is adjusted by a flow control switching valve 21 driven by a flow control motor or the like, and the flow switching valve 2
2 is sent. Here, the heater 182 can use, for example, a sheathed heater, and the cooler 192 can be, for example, a cooler using a Peltier element, but may be another type.

The flow control switching valve 20 adjusts the flow rate of the washing water sent to the flow path switching valve 22 and removes dirt adhering to the nozzle itself at a predetermined time such as before and after local cleaning. 46 also has a function of switching a flow path for discharging water. Except for this switching function, the flow control function of the flow control switching valves 20 and 21 may be realized by a flow control pump.

The flow switching valve 22 switches between the hot water sent from the flow control switching valve 20 and the cold water sent from the flow control switching valve 21 as described later, and sends it to the bubble mixing unit 23. Such washing water is supplied to the bubble mixing unit 2.
When passing through the air bubble mixing section 231 included in No. 3, appropriate air bubbles are mixed into the cleaning water. The flow path switching valve 24 downstream of the bubble mixing section 231 connects the supply destination of the cleaning water sent from the upstream with the butt cleaning water passage 33 of the nozzle unit 30,
It switches to either the soft washing water passage 34 or the bidet washing water passage 35.

The nozzle unit 30 includes a nozzle body 31
And a nozzle driving unit 32 for extending and retracting the nozzle body 31. At the ends of the buttocks washing water passage 33, the soft washing water passage 34, and the bidet washing water passage 35 disposed inside the nozzle body 31, the buttocks discharge hole 3 is provided.
6. Soft water discharge holes 37 and bidet water discharge holes 38 are formed. Thus, when the electromagnetic valve 15 of the water inlet side valve unit 10 is opened, the water is heated by the heating unit 18 or cooled by the cooling unit 19 and adjusted to a predetermined flow rate by the flow control switching valves 20 and 21. The washing water selected by the flow path switching valve 22 is supplied to the water discharge port 36 of the water supply destination selected by the flow path switching valve 24,
Water is discharged from 37 or 38.

The detailed configuration of the nozzle unit 30 and the extending / retracting operation of the nozzle body 31 will be described. FIG. 2 is a detailed configuration diagram of the nozzle unit 30. Nozzle unit 30
Is a nozzle drive motor 3 which is a part of the nozzle drive unit 32
2a (not shown in FIG. 2) includes a driving pulley 41 that is rotationally driven, and two driven pulleys 42 and 43. These three pulleys 41, 42, and 43 include:
A timing belt whose inner surface is shaped like a sawtooth
A belt 44 is simply wound around the tensioner 45 with an appropriate tension applied thereto. The nozzle body 31 having the nozzle head 46 at the tip is provided with a nozzle holder 4 slidably provided on a nozzle guide 47.
8 is fixed to the front part. A latch 49 provided on the side of the nozzle holder 48 holds the belt 44 from above and below.

When the driving pulley 41 is driven to rotate in a predetermined direction (clockwise in FIG. 2) by the nozzle driving motor 32a, the belt 4 is moved between the driven pulleys 42 and 43.
4 moves obliquely forward and downward with the nozzle holder 48, whereby the nozzle body 31 extends obliquely forward and downward. When the nozzle drive motor 32a drives the drive pulley 41 to rotate in the reverse direction, the nozzle body 31 retreats obliquely upward and rearward. In this way, the nozzle head 46 is extended from the predetermined standby position to the buttocks cleaning position or the bidet cleaning position in front of it, or conversely, is retracted from those cleaning positions to the original standby position.

Next, the configuration and operation of the bubble mixing unit 23 in the above configuration will be described in more detail. In the bubble mixing unit 23, the air pressurized by the air pump 233 is sent to the bubble mixing unit 231 through the air flow regulating valve 232, so that bubbles can be mixed in the cleaning water at a predetermined ratio.

FIG. 3 is a schematic sectional view of the bubble mixing section 231. In the figure, the washing water flows from left to right. An air chamber 2312 communicating with the air introduction pipe 2313 is formed inside the housing 2311, and a cylindrical shape is formed on the inner peripheral side of the air chamber 2312 so that the washing water flows continuously inside the washing water pipe. A foam dispersion 2314 is provided. The cell dispersion 2314 is made of a porous material having a large number of micropores. The minute aperture has a fine size such that water does not seep to the outside at the pressure of the washing water passing through the inside, and air can be sent from the outside to the inside by the pressure difference between the inside and the outside. . For example, the bubble dispersion 231
No. 4 can be formed by heating and molding substantially spherical particles of ultrahigh molecular weight polyethylene resin.

After the flow rate of the air pressurized by the air pump 233 is controlled by the air flow regulating valve 232,
When the air is sent to the air chamber 2312 through 13, the air is sent from the opening of the bubble dispersing element 2314 into the pipe, and expands at each opening. When the bubbles expand to a predetermined size, the bubbles are cut off by the shearing force received from the washing water flowing in the pipeline, and are individually mixed into the washing water. For example,
The diameter of the pores of the cell dispersion 2314 is preferably determined so that the diameter of the formed cells is about 100 to 1000 μm. In this configuration, the air mixing rate is determined according to the amount of air mixed into the washing water flowing in the pipeline. Of the air (bubbles) can be determined by the degree of opening.

In the human body local cleaning device 1 of the present embodiment, in particular, the water discharged from the water discharge hole 36 provided in the nozzle head 46 can be changed so as to change the water discharge form. A predetermined trajectory water discharge control means for controlling the cleaning water to draw a predetermined trajectory is provided. In the present embodiment, the predetermined trajectory water discharge control means includes, as main components, an armature that generates a magnetic field when energized, and a movable body that itself has magnetism and moves by interaction with a magnetic field generated by the armature. Actuator.

Next, the structure and operation of this actuator will be described with reference to FIG. FIG. 4 is a schematic sectional view (a) and a perspective oblique view (b) showing a configuration of a main part of the nozzle head 46. In FIG. 4, only the configuration of the predetermined trajectory water discharge control means related to the buttocks discharge hole 36 is described, and the description of the components related to bidet cleaning and soft cleaning is omitted. The hole 38 may be provided with a predetermined trajectory water discharge control means having the same or similar configuration.

In FIG. 4, the movable body 60 having a substantially cylindrical shape has a moving water passage 62 inside, and an upper opening of the moving water passage 62 is a bottom water discharge hole 36. Mobile waterway 62
Is connected to the buttocks washing water passage 33 provided inside the nozzle body 31 by an elastic connecting pipe 63 such as a rubber pipe or a bellows-shaped pipe, and is washed through the connecting pipe 63. Water is flowing. An annular ferromagnetic body 61 is integrally provided on the outer peripheral side of the movable body 60,
An annular electromagnetic coil 65 is provided on the outside thereof with a gap 64 therebetween.
Are arranged. The electromagnetic coil 65 is connected to the nozzle head 46
Since it is buried inside, it is not flooded, and high reliability can be maintained for a long time.

As shown in FIG. 4B, the electromagnetic coil 65
Has a structure radially divided into a plurality in the circumferential direction. When a current is applied to any one of the plurality of electromagnetic coils 65, a magnetic field is generated in a space surrounded by the electromagnetic coils 65, and an attractive force or a repulsive force acts on the ferromagnetic material 61. As described above, since the movable body 60 is connected through the elastic connecting pipe 63, any movement can be performed within the space 64 in the radial direction with respect to the axis C. Therefore, the movable body 60 moves in the direction of the energized electromagnetic coil 65 or in the opposite direction. Thus, by controlling the energization of the electromagnetic coil 65, the movable body 60, that is, the buttocks discharge hole 36 rotates, substantially rotates, or swings without rotating around the axis C. By appropriately controlling the drive current, it is possible to change not only the moving direction of the movable body 60 but also the magnitude and speed of the movement (period in the case of repetitive movement).

FIG. 5 is a schematic view showing an example of the trajectory of the washing water discharged from the buttocks discharge hole 36. For example, movable body 6
If the washing water is discharged from the buttocks discharge hole 36 while controlling the energization to the electromagnetic coil 65 so that 0 rotates in a spiral shape, the cleaning water spirally moves with the movement of the discharge hole 36. Draw a turning trajectory. Although the area of the area A0 on the object to be washed with the washing water is small when viewed instantaneously, the area A0 moves along the trajectory, so that the washing water can be applied to the whole of the wide washing range A1. Further, the area of the cleaning range A1 can be appropriately set in accordance with the control of energization of the electromagnetic coil 65. Note that the actuator used here is disclosed by the present applicant in Japanese Patent Application No. 11-1.
This is one of those proposed in Japanese Patent No. 69767 (see Japanese Patent Application Laid-Open No. 2000-240131).

The predetermined trajectory water discharge control means, in which the discharged cleaning water turns in a so-called helical manner, sees the cleaning water at a moment in a certain part within a predetermined cleaning range A1. However, in the local area, the washing water is applied intermittently. That is, this corresponds to spatial intermittent water discharge. In such an intermittent water discharge, it is possible to avoid a stimulus having a substantially constant intensity from continuing to the local area.

FIG. 6 is a block diagram showing the electrical system of the main part of the apparatus for cleaning a human body part according to this embodiment. At the center of the control, a control unit 70 configured using a microcomputer or the like is installed. The control unit 70 includes a plurality of such as a bottom cleaning key 721, a bidet cleaning key 722, a hemorrhoid treatment key 723, and a stop key 724. A key input signal from an operation unit 72 having operation keys, a seating detection signal from a seating sensor 73 provided on the toilet seat are input water temperature sensors 183, 193, and an output water temperature sensor 18.
The water temperature detection signal is output from the float switch 18
5, 195, water level detection signals of the heat exchange units 181, 191; a fall detection sensor 74; a detection signal corresponding to the tilting state of the human body local cleaning device 1; A detection signal of the amount of washing water in the water supply line is input. The control unit 70 receives the input signals, performs predetermined processing, and performs, via the load driving unit 71, the electromagnetic valve 15, the heater 182, the cooler 192, and the flow control switching valve 2.
0, 21, flow path switching valve 22, air pump 233, air flow regulating valve 232, flow path switching valve 24, nozzle drive motor 32
a, in addition to the electromagnetic coil 65, a drying unit 76 including a drying heater and a fan motor for drying the human body part, a deodorizing unit 77 including an ozonizer and a suction fan motor for removing odor, and a heater and a fan motor for heating the toilet room. Heating section 78 including
Are appropriately controlled, and display control is performed on the display unit 79.

A description will now be given of the operation of the main body part cleaning apparatus 1 having the above-described configuration during normal hip cleaning. When the user sits on the toilet seat, the control unit 70 recognizes the seating based on the seating detection signal from the seating sensor 73. At this time, the nozzle main body 31 is retracted to the rearmost position, so that the nozzle main body 31 does not obstruct defecation. After defecation, the user presses the bottom cleaning key 72 of the operation unit 72.
1 is operated, the control unit 70 controls the nozzle driving motor 32a.
, The nozzle body 31 is advanced integrally to the buttocks washing position as described above, the electromagnetic valve 15 is opened, the flow path switching valve 22 selects the hot water side, and the flow path switching valve 24 is A flow path is connected to the tail washing water passage 33. Then, water flows into the heat exchange unit 181 of the heating unit 18,
The hot water pushed by this and already stored in the heat exchange section 181 passes through the flow control switching valve 20, passes through the flow path switching valve 22, the bubble mixing unit 23, and flows from the flow path switching valve 24 to the bottom of the nozzle unit 30. The water is sent to the washing water passage 33. Then, as described above, the hot water flows through the movable water passage 6 through the connecting pipe 63.
2 and is discharged from the tail water discharge hole 36. At this time,
By appropriately energizing the electromagnetic coil 65, the washing water discharged from the buttocks discharge hole 36 moves so as to draw a predetermined trajectory, and a wide area near the user's anus can be washed.

Next, the operation of the present embodiment during the treatment of hemorrhoids, that is, the operation in the blood circulation promoting mode, will be described with reference to FIG.

When the user is seated on the toilet seat, the operation unit 72
When the hemorrhoid treatment key 723 is operated, the control unit 70 advances the nozzle body 31 integrally to the buttocks washing position, opens the electromagnetic valve 15, and causes the flow path switching valve 24 to flow into the buttocks washing water passage 33. Connect roads. In addition, the flow path switching valve 2
The reference numeral 2 designates a downstream side flow of a hot water side flow path (flow path on the flow control switching valve 20 side) and a cold water flow path (flow path on the flow control switching valve 21 side) alternately at a predetermined cycle (that is, hot / cooling cycle). It is controlled to connect to the road. At this time, in the heat exchanging unit 181 of the heating unit 18 and the heat exchanging unit 191 of the cooling unit 19, the temperature is adjusted so that the washing water has the predetermined temperatures Th and TL, respectively. Therefore, in the downstream flow path of the flow path switching valve 22,
The washing water at the temperature Th and the washing water at the temperature TL are alternately sent out in the above-mentioned warming and cooling cycle, and appropriate bubbles are mixed in the washing water. The water is sent to the water channel 33. As a result, the warm washing water and the cold washing water are alternately discharged from the buttocks discharge hole 36 in the warm / cool cycle. Actually, the temperature does not change abruptly due to the heat capacity of the pipeline or the like, so that the temperature of the washing water discharged from the buttocks discharge hole 36 changes, for example, as shown in FIG. In this example, the time for discharging the warm cleaning water is set longer than the time for discharging the cold cleaning water. In general, the response of the human body to relax or contract when blood vessels are warmed or cooled is not so good following,
Normally, the hot and cold alternation will be at a much lower frequency. According to the monitor evaluation performed by the present inventors, from the viewpoint of physical relaxation, the warming / cooling cycle (warming time + cooling time) varies from person to person, but is preferably about 2 to 10 seconds. It was an opinion.

At the same time as the warm / cool change of the washing water, the control unit 70 controls the electromagnetic coil 65 so as to maintain the same cycle as the warm / cool cycle and a predetermined relationship with the timing of the warm / cool change. Change the energization pattern. For example, in this example, as described above, by changing the pattern of energization to the electromagnetic coil 65, the cleaning area, which is one of the water discharge modes, can be changed. Therefore, as shown in FIG.
The power supply pattern to the electromagnetic coil 65 is changed so that the cleaning area change cycle (water discharge mode cycle) is the same as the warm / cool cycle and the phase relationship is a predetermined relationship.

FIG. 8 is a schematic diagram showing the relationship between the user's buttocks B and the arrival position of the washing water when the washing area is changed. FIG. 8A shows a case where the excitation of the electromagnetic coil 65 is controlled so that the tail water discharge hole 36 is stationary or moves in a very narrow range substantially at the center of the movable range (that is, on the axis C). The cleaning water discharged from the water discharge hole 36 proceeds substantially straight and reaches a narrow area centered on the anus B1. Since much of the washing water discharged in this way enters the anus B1,
The user does not feel much vibration due to the water spray hitting the skin, and the stimulation is relatively weak. However, a secondary effect of promoting water in the anus by promoting water in the anus can be expected. It is possible that the anus is closed and irrigation water does not penetrate into the anus, but originally the central part of the anus has less pain and less pain. Therefore, the irritation is weaker than when the washing water is applied to the periphery of the anus.

On the other hand, FIG. 8B shows that the excitation of the electromagnetic coil 65 is controlled such that the buttocks discharge hole 36 rotates around the axis C while changing the distance from the axis C within a predetermined range. In this case, the washing water discharged from the buttocks discharge hole 36 draws a spiral as if it were formed, and a peripheral portion B2 surrounding the anus B1.
(Strictly speaking, sequential scanning is performed within the wide area). In this case, the user feels a stronger stimulus than when the washing water is intensively applied to the anus. This is because, in addition to the fact that pain points are more distributed around the anus, especially when the movement speed of the buttocks discharge hole 36 is relatively slow, intermittent contact of water with each part due to the movement is prevented. The user perceives the water stimulus relatively strongly because it is easier to perceive.

In the human body local cleaning device 1, the electromagnetic coil 6
By periodically changing the excitation pattern of No. 5, the water discharge with the different cleaning areas as described above is periodically repeated. Specifically, the movable body 6 is applied by applying a rectangular wave DC voltage (current) to each of the plurality of electromagnetic coils 65.
When moving 0, for example, the cleaning area can be changed by changing the magnitude of the applied voltage (current). Also, the ON time of the applied voltage (that is, the duty ratio)
It is also possible to change the washing area by changing.

In the example shown in FIG. 7, the cleaning area is large during the period when the temperature of the cleaning water is high, so that mechanical stimulation is increased. Conversely, the cleaning area is reduced during the period when the temperature of the cleaning water is low, so that the mechanical stimulation is reduced. That is, the timing at which the blood vessel is relaxed due to the hot washing water hitting the local part matches the timing at which the mechanical stimulus is applied to the blood vessel, and the difference between the warm stimulus and the cold stimulus becomes more prominent due to the mechanical stimulus. For this reason, the massage effect works very effectively. Here, if the warming / cooling cycle is adjusted to the rhythm of the human body such as relaxation / contraction of blood vessels, heartbeat, etc., a higher effect can be obtained.

In FIG. 7A, the high-temperature period is longer than the low-temperature period. However, the high-temperature period and the low-temperature period may be substantially the same, or the low-temperature period may be longer. Such adjustment can be easily changed by controlling the switching operation of the flow path switching valve 22.

The temperatures Th and TL of the washing water can be appropriately set within the range of the capabilities of the heater 182 and the cooler 192. However, from the viewpoint of promoting the contraction and relaxation of blood vessels in order to obtain a blood circulation promoting effect,
There is a suitable temperature. In general, hot water is 4
It is said that about 0 ° C. and about 20 ° C. cold water are suitable. If the temperature of the hot water is higher than this, it is often felt that the temperature is too hot, not only causing discomfort but also tensing the body and may have an adverse effect on promoting blood circulation. Therefore, about 40 ° C. is appropriate for the hot water. The relationship between the temperature difference between such hot water and cold water and the effect of promoting blood circulation was monitored and monitored.
According to the results, (1) a temperature difference of less than 5 ° C .: not only the blood circulation promoting effect is extremely poor, but also a slight fluctuation of the water temperature gives anxiety and discomfort to the user, and some people have malfunctioned the device. You may feel it. (2) Temperature difference 5 ° C. to 10 ° C .: Although it takes a certain time, there is an effect of promoting blood circulation. (3) Temperature difference 10 ° C. to 15 ° C. In addition to the effect of promoting blood circulation,
A hot and cold massage effect can also be obtained. (4) Temperature difference 15 ° C. to 20 ° C. In addition to a blood circulation promoting effect and a warm / cold massage effect, an effect of promoting constipation is also obtained. (5) 20 ° C. or higher: Each of the above effects can be obtained in a relatively short time use. Therefore, it is suitable for people who cannot take enough time or who are short-tempered.

From these results, it is very effective to have a temperature difference of about 20 ° C. However, cold water at 20 ° C. may be felt considerably cold depending on individual differences and physical condition at that time, so that the temperature may be slightly increased particularly at the beginning of washing. Even in such a case, it is preferable that the initial cold water temperature is set to about 33 ° C. or less so that a certain degree of blood circulation promoting effect is obtained from the initial stage, and with the lapse of time from such an initial temperature. It is preferable to gradually lower the temperature of the cold water so that a sufficient temperature difference can be finally secured.

In the example of FIG. 7, the heating / cooling cycle and the water discharge mode cycle are the same. By setting to, a wide variety of cleaning can be provided. FIG. 9 shows an example in which the heating / cooling cycle is longer than the water discharge mode and maintaining the synchronous relationship between them, and FIG. This is an example in the case of maintaining. In addition, in the example of FIG. 9, the amount of change in the form of water discharge is periodically increased, but is not limited to this.

In the case of water discharge as shown in FIG. 9, the intensity of mechanical stimulation occurs a plurality of times while the temperature of the washing water changes for one cycle. For this reason, it is suitable for a person who prefers a relatively intense change in water discharge stimulus. There is also an advantage that the water is not monotonously discharged. On the other hand, in the spouting shown in FIG. 10, the intensity of the mechanical stimulus is 1 while the temperature of the washing water changes over a plurality of cycles.
Only occurs once. Therefore, it is suitable for a person who prefers a relatively gentle change in the water discharge stimulus. In addition, a relaxed feeling can be given to the user, which is effective in relieving the body tension.

In the human body local cleaning apparatus 1 having the above configuration, various methods other than those described above can be used to change the form of water discharge. As an example, the control of changing the frequency of the voltage applied to the electromagnetic coil 65 for moving the movable body 60 can be performed to change the cleaning area. When the frequency (excitation frequency) of the voltage applied to the electromagnetic coil 65 is changed, the movable body 60,
6, the moving speed (that is, the moving frequency) changes. The influence of the change in the moving frequency on the cleaning area has several factors as follows.

First, there is an influence of the natural frequency. As shown in FIG. 4A, since the movable body 60 is connected to the nozzle head 46 via the connection pipe 63 made of an elastic body, the movable body 60 is restrained by the connection pipe 63 when the movable body 60 moves. . The movable body 60 has a natural frequency depending on its size, weight, and the like. When a force acts at a frequency near the frequency, a large vibration is generated by resonance. Therefore, when the excitation frequency is appropriately adjusted and the moving frequency of the movable body 60 is set near the natural frequency, the movable body 60 itself largely rotates or swings due to resonance, and the cleaning area is increased.

The second is the action of the force generated by the movement. Overall, the cleaning area tends to increase with increasing frequency up to a certain extent. This is based on the following principle. Considering the direction in which the washing water is spouted from the butt spout hole 36, first, the spouting is performed in a state where the spout does not draw a predetermined trajectory, that is, the butt spout hole 36 and the nozzle 46 themselves are still. As shown in FIG. 11A, the water discharge direction is the vertical velocity component (M1
Component) alone. When water is discharged so as to draw a predetermined trajectory, that is, when the buttocks discharge hole 36 rotates or swings, as shown in FIG. It is determined as a combination of a horizontal speed component (M2 component) along the movement trajectory of the hole 36 and a speed component (M3 component) due to a force against the acceleration generated when the direction of the movement trajectory of the water discharge hole 36 is changed. . In other words, when the water discharge draws a predetermined trajectory, the water discharge direction is obtained by adding the M1 component and the M2 component compared to when the predetermined trajectory is not drawn. At this time, the influence of the M2 component and the M3 component differs depending on the magnitude of the moving frequency of the tail water discharge hole 36, and as a result, the cleaning area differs.

When the moving frequency is increased, as shown in FIG. 11D, both the M2 component and the M3 component are greatly added. As a result, as shown in FIG. The cleaning area becomes large. Conversely, when the moving frequency is lowered, the degree of addition of the M2 component and the M3 component is reduced as shown in FIG.
As shown in (e), the cleaning area is larger than when the predetermined trajectory is not drawn, but the cleaning area is smaller than when the moving frequency is high as described above. As described above, the cleaning area can be varied depending on the level of the moving frequency, separately from the above-described resonance. However, the moving speed of the movable body 60 is limited, and if the excitation frequency is too high, the movable body 60 cannot follow. In that case, the movable body 60 stays near the central axis C, and the cleaning area is reduced.

As described above, a plurality of factors contribute to the relationship between the moving frequency of the buttocks discharge hole 36 and the washing area, but the reproducibility is extremely high. The cleaning area can be varied by controlling the moving frequency, that is, by the excitation frequency.

Further, as described above, since the nozzle body 31 can be moved in the front-rear direction by the nozzle driving unit 32, the washing area can be changed by such movement. In this case, similarly to the operation of the actuator, a relatively strong stimulus can be obtained by increasing the stroke of movement and increasing the cleaning area. In addition, as the moving speed increases, spatial perception of intermittent water discharge becomes more difficult, and the stimulus relatively weakens. There is a physical limitation on the increase of the cleaning area due to the operation of the actuator, and the cleaning area cannot be increased so much. However, by combining with the movement of the nozzle body 31, the cleaning area can be further increased, and The area can be heated and cooled.

In the above configuration, the bubble mixing unit 2
The intensity of the stimulus may be changed by controlling the amount of air bubbles mixed into the washing water according to (3). In the bubble mixing unit 23, if the amount of air bubbles is increased, the feeling of irritation caused by water discharge is reduced, and if the amount of air bubbles is reduced, the feeling of irritation is increased. Such control of the air bubble mixing amount can be achieved by controlling the opening degree of the air flow regulating valve 232.
That is, in this case, not the predetermined trajectory water discharge control means but the air mixing means corresponds to the water discharge form control means.

When the opening of the flow control switching valves 20 and 21 is controlled, the flow rate of the washing water supplied to the nozzle unit 30 per unit time is changed. The stimulus may be weakened by reducing the flow rate. However, in general, when the structure of the flow regulating valve is simplified, the responsiveness of the opening degree is not good, and it may not be possible to follow a short water discharge form cycle. Even in such a case, for example, as shown in FIG. 10, the present invention can be sufficiently applied for the purpose of setting a long water discharge mode cycle.

Next, an example of a modification of the structure of the actuator shown in FIG. 4 will be described. FIG. 12 is a diagram showing the configuration of this actuator, where (a) is a schematic sectional view,
(B) is a top perspective view. In this actuator, the movable body 90 includes a flange portion 91 fixed to the upper surface of the cover 46a of the nozzle head 46, and the flange portion 91.
And a water discharge piece 93 fitted with a central through hole of the cylindrical part 92 and having a tail water discharge hole 36 at the center thereof. And a magnetically actuated body 94 that is widely extended on the side. The flange portion 91 and the cylindrical portion 92 are integrally molded products made of a resilient material having a deformation restoring property, such as rubber and an elastomer. The water discharge piece 93 is a resin molded product, and a lower end side of the buttocks water discharge hole 36 is formed in a large-diameter water discharge guide hole 36a. Since the movable body 90 is fixed to the cover 46a at the periphery of the flange portion 91, the movable body 90 is suspended and supported by the flange portion 91, and can be swung in each direction by deforming and restoring a connecting portion between the flange portion 91 and the cylindrical portion 92. It has become.

Below the movable body 90, the ass washing water passage 3
A protruding portion 95 having a head bottom water discharge hole 33a substantially in the center communicating with No. 3 is formed with an appropriate gap between the lower surface of the movable body 90 and the protrusion 95. Also, three electromagnetic coils 96 are arranged circumferentially and separated by a predetermined distance so as to surround the protruding portion 95. Each electromagnetic coil 96 has the same configuration, and is provided with two cores (iron cores) 97 standing upright at a predetermined interval.
a, 97b and a coil 9 wound around one core 97a
8 is provided. When the coil 98 is energized, a magnetic flux that circulates around the two cores 97 a and 97 b is generated, and the resulting magnetic field acts on the magnetic operating body 94 of the movable body 90.

When a magnetic attraction force acts on the magnetic operating member 94, the corresponding magnetic operating member 94 moves downward, and the movable member 90, that is, the buttocks discharge hole 36 is positioned below the magnetic operating member 94. Tilt as you move. Then, for example, if each electromagnetic coil 96 is sequentially energized in a counterclockwise or clockwise direction to excite it, the magnetic actuating body 94 attracted downward moves accordingly, and the tail water discharge hole 36 is accordingly inclined. It sequentially moves three-dimensionally clockwise or counterclockwise. The swing angle α of the buttocks discharge hole 36 adjusts the strength of the suction force, that is, the voltage value (current value) of the voltage applied to the electromagnetic coil 96 (strictly, the coil 98) and the duty ratio of the voltage applied. Can be controlled. Further, since the movable body 90 is supported by the flange portion 91 which is an elastic body and has a natural frequency, the swing angle α can be controlled by controlling the frequency of the energized voltage of the electromagnetic coil 96 as described above. .

In the above configuration, when the washing water is supplied to the buttocks washing water passage 33, water is jetted from the buttocks water discharging hole 33a in the head and the buttocks water discharging hole 36a of the movable body 90 is discharged. Water is discharged from 36. Since the area of the upper and lower openings across the gap at the lower end of the movable body 90 is wider on the upper side, when the cleaning water passes through the gap, the surrounding air is entrained and discharged in a state containing bubbles. Therefore, bubbles can be included at an appropriate ratio without providing the bubble mixing unit as described above. By controlling the energization of the three electromagnetic coils 96 as described above while performing such water discharging, the cleaning water can reach a wide range by tilting the tail water discharging hole 36. In addition, by appropriately controlling the voltage value of the energizing voltage, the duty ratio of the energizing voltage, or the frequency, etc., the swing angle α of the buttocks discharge hole 36 is varied, and as a result, the washing water is concentrated on the anus. Water spraying with a small washing area to apply water and water spraying to apply cleaning water widely around the anus can be alternately performed.

Various means other than those described above can be used for driving the water outlet. For example, a motor for rotating the movable body about an axis is provided by indirectly connecting the movable water passage provided on the movable body and the immovable water passage provided on the nozzle body side. Then, while the movable body is rotated by the motor, the washing water supplied from the immovable water passage to the moving water passage is jetted from the water discharge hole, so that the washing water draws a predetermined trajectory. Of course, an appropriate power transmission mechanism such as a gear or a crank may be interposed between the motor and the movable body.
Further, the direction of the cleaning water spouting from the water discharge hole may be periodically switched using a fluid oscillation element utilizing the so-called Coanda effect (fluid adhesion effect). In this case,
Since the switching cycle of the discharge direction of the washing water depends on the flow rate of the washing water, the flow rate may be determined according to the cycle of switching between the hot water and the cold water.

In addition, the predetermined trajectory water discharge control means can perform various modifications. Regarding the configuration of such means and the details of its operation, the applicant of the present invention has disclosed in Japanese Patent Application No.
It has already been proposed in 69767 and the like.

Next, a human body local cleaning apparatus according to another embodiment of the present invention will be described. FIG. 13 is a configuration diagram centering on a water flow path of the human body local cleaning device 2 according to the second embodiment. The same components as those in the first embodiment shown in FIG. 1 are denoted by the same reference numerals, and description thereof will be omitted. The water inlet side valve unit 210 of the human body local cleaning device 2 differs from the water inlet side valve unit 10 of FIG. 1 in that the water inlet side valve unit 210 has a pressure regulating valve 214 instead of the constant flow valve 14. By the pressure regulating valve 214, the cleaning water is supplied to a predetermined pressure (primary pressure: for example, about 1.0 kgf).
/ Cm ² ), flows into the heating unit 18 and the cooling unit 19 via opening and closing of the solenoid valve 15.
The cleaning water heated and cooled by the heating unit 18 and the cooling unit 19 respectively flows into the flow control switching valves 20 and 2.
After the flow rate is adjusted by 1, it is selected by the flow path switching valve 22 and flows into the wave generator 25.

The configuration of the wave generator 25 will be described with reference to FIG. The wave generator 25 is connected to the upstream water supply line 25.
6 and cylinder 25 connected to downstream water supply line 257
A plunger 252 is slidably provided inside the unit 1. The plunger 252 has a flow path 252 a communicating the upstream side and the downstream side inside, and slides in the upstream and downstream directions by exciting control of an electromagnetic coil (pulsation generating coil) 253 provided outside the cylinder 251. I do. The plunger 252 moves downstream from the original position shown by the excitation of the electromagnetic coil 253, but when the excitation of the electromagnetic coil 253 is lost, the plunger 252 receives the urging force of the upstream spring 254 and the downstream spring 255 and returns to the original position. I do.

The plunger 252 has a flow path 252 therein.
A is provided with a check valve 256 composed of a steel ball and a spring, and when moving downstream from the original position, pressurizes the wash water in the cylinder 251 and flushes it to the downstream water supply conduit 257. Since the original position of the plunger 252 is constant,
A certain amount of washing water is sent to the downstream water supply line 257.
Thereafter, when the plunger 252 returns to the original position, the check valve 256 is opened, and the cylinder 2 is moved through the flow path 252a.
Since the washing water flows into the inside of the plunger 51, the next plunger 25
Due to the movement of 2 in the downstream direction, a certain amount of washing water is again sent to the downstream water supply line 257. In addition, when the plunger 252 returns to its original position,
Of the washing water in the downstream side, that is, in the downstream side water supply line 257, is generated.
Generates a pulsation in which the pressure periodically fluctuates in accordance with the reciprocation of the plunger 252, and causes the washing water to flow to the downstream water supply pipe 257 in a pulsating flow state.

The wave generator 25 includes an upstream water supply line 25.
Cleaning water at a predetermined pressure (in this example, a primary pressure determined by the pressure regulating valve 214) is supplied through 6. Therefore, as described above, the washing water flowing into the cylinder 251 via the flow path 252a while the plunger 252 returns to the original position is affected by the pressure loss by the check valve 256 and the suction of the washing water on the downstream side. Thus, the pressure is reduced from the primary pressure, but is sent to the downstream water supply line 257. FIG. 15 shows this state. As shown in FIG. 15, the washing water is sent from the wave generator 25 to the downstream water supply pipe 257 and eventually to the nozzle unit 30 at a pressure pulsating about the primary pressure, and is discharged from the water discharge hole 36. Moreover, the pressure of the washing water sent from the wave generator 25 to the downstream side does not become zero due to the inflow of the washing water through the flow path 252a when the plunger 252 returns to its original position. Such pressure pulsation of the washing water
As a result, the fluctuation of the flow rate of the washing water is reflected.

The pulsation cycle MT shown in FIG. 15 is synchronized with the excitation cycle of the electromagnetic coil 253, and can be set variously by changing or changing this excitation cycle. In order to generate a pulsating flow of washing water, an electromagnetic coil 25 is required.
Since only the third excitation needs to be performed, the configuration of the wave generator 25 is simple. The wave generator 25 generates a pulsation in the flow of the washing water according to the above-described coil excitation control, and causes a pressure fluctuation of the washing water. At the same time, fluctuations in the speed (flow velocity) and flow rate of the washing water can also occur. The wave generator 25 is provided with a plunger 252 in the cylinder 251.
May be reciprocated, the cylinder 251 may be a part of the pipeline, and the coil may be disposed around the cylinder. Therefore, the wave generator 25 can be integrated with the nozzle main body 31 or can be installed inside the nozzle main body 31.

In order to change the water discharge mode, here the water pressure, flow rate, flow velocity, etc. of the discharged washing water, the electromagnetic coil 2
The frequency control and the duty ratio control of the excitation signal for exciting the 53 may be performed. FIG.
3A and 3B are diagrams illustrating control examples when the excitation frequency is changed, wherein FIG. 3A is an example when the excitation frequency is low, and FIG. 3B is an example when the excitation frequency is high. As shown in FIG. 16, when the excitation frequency of the electromagnetic coil 253 is changed, the pulsation frequency changes while the pressure change width (pulsation flow amplitude) is almost constant.

FIG. 17 is a schematic view of the state of water discharge when the pulsating flow is changed as described above.
53 shows an example where the excitation frequency is low, and FIG. When the pulsating flow is generated by the wave generator 25, the flow rate becomes uneven in terms of time, and the washing water discharged from the buttocks discharge port 36 alternately generates a portion having a large flow rate (flow velocity, water pressure) and a small portion. I do. When the pulsation frequency is low, it becomes easy to perceive the difference between the vibration in the portion with a large flow rate and the vibration in the portion with a small flow rate, and a strong stimulus is felt by repeating such vibration. However, when the pulsation frequency increases, the user's perception of the vibration based on intentional repeated water discharge cannot be followed, and the user feels as a continuous stimulus. Generally, when the repetition frequency is 10 Hz or more (hereinafter, such a frequency is referred to as a “dead band frequency”), the majority of persons having a normal perception cannot perceive the repetition stimulus repeatedly. Furthermore,
Normally, when the frequency exceeds 5 Hz, the flow approaches a continuous flow and is felt as a soft water flow, and when the frequency exceeds about 30 Hz, it is almost impossible to distinguish the flow from the continuous flow. Further, even if the pulsation frequency is set to the dead band frequency, the sense of continuous spouting received from the continuous spouting of the wash water tends to be weaker as the pulsation frequency is lower.

Thus, even in the range of the dead band frequency, if the pulsation frequency is relatively low as shown in FIGS. Washing, and a strong irritating feeling can be obtained. On the other hand, as shown in FIG. 16B and FIG. 17B, when the pulsation frequency is relatively high, a washing sensation as if a relatively weak stimulating feeling is continuously received is obtained, and a soft stimulating feeling is obtained. be able to. Of course, in order to provide a stronger stimulus, the pulsation frequency may be lowered until the frequency falls outside the dead band frequency. In any case, by periodically changing the excitation frequency of the electromagnetic coil 253 in this way, the form of water discharge can be changed periodically, and the sense of irritation given to the user can be changed periodically. In addition, in achieving such various washing feelings, the amount of washing water to be used can be reduced, which is also effective in saving water.

When the duty ratio control is performed instead of the excitation frequency control, the frequency of the excitation signal is kept constant and the duty ratio Dt is periodically changed as shown in FIG. Since the duty ratio Dt determines the coil exciting force, that is, the moving speed and the moving amount of the plunger 252 in the wave generator 25, as shown in FIG. can do. Since the amplitude of the pulsation affects the flow rate and the flow velocity of the washing water, the intensity of the stimulus can be adjusted as a result. Since the duty ratio control and the frequency control are not related to the flow rate adjustment by the flow control switching valves 20 and 21, the adjustment of the water force which cannot be performed by the flow control by the flow control switching valves 20 and 21 is performed. It can be realized by both of the above controls. That is, the duty ratio control and the frequency control can complement the flow rate adjusting functions of the flow control switching valves 20 and 21.

Although the flow rate is made uneven in the above-described configuration, the same applies to intermittent water discharge in which wash water is intermittently discharged. Further, in addition to the wave generator 25 having the above-described configuration, it is possible to impart temporal density to the flow rate, the flow velocity, and the water pressure by various methods. For example, it can be realized by controlling a pressure regulating valve, controlling a flow pump, and the like.

Next, a human body part cleaning apparatus according to still another embodiment of the present invention will be described. The basic configuration of the human body cleaning apparatus according to the third embodiment is the same as that of the example shown in FIG. 13 except that the air bubble mixing unit 23 is not provided. This is different from the second embodiment. FIG. 19 is a schematic perspective view showing the internal structure of the nozzle head 300 in this human body local cleaning apparatus, and FIG. In this embodiment, the nozzle head 300 functions as a water discharge mode control unit.

As shown in FIG. 19, this nozzle head 3
Reference numeral 00 denotes an outside air entrapment chamber 301, an orifice 302, a tail water discharge hole 303 as a throat, and an outside air introduction passage 304.
Having an orifice 302
A washing water vortex chamber 305 is provided between the butt washing water passage 306 and the butt washing water passage 306. The cleaning water vortex chamber 305 has a larger diameter toward the bottom, and has a conical inner peripheral wall inclined from the bottom to the orifice 302. The buttocks washing water passage 306 is eccentrically connected to the washing water vortex chamber 305 as shown in FIG.
As shown by the arrow in FIG. 9, the vehicle turns along the inclined inner peripheral wall. The swirled washing water is discharged in a state where a large amount of air is entrained when it is discharged from the throat through the orifice 302 and the outside air entrainment chamber 301.

The discharged cleaning water is affected by the swirling force of the cleaning water itself, and takes a spiral water discharge form as schematically shown in FIG. Wash water vortex chamber 30
When the washing water flows into the butt 5, the ass washing water passage 3
From 06, the washing water is supplied in the pulsating flow (or intermittent flow) state. Therefore, the washing water discharged as described above is
As shown by F1 in FIG. 19, a water discharge form having a cone shape and a spiral shape is taken in a state in which air is mixed, while having the property of water discharge in this pulsating flow (or intermittent flow). The swirling force of the cleaning water is the flow rate (flow velocity) of the cleaning water into the cleaning water vortex chamber 305.
Is determined by Therefore, by adjusting the flow rate of the washing water to the washing water vortex chamber 305, it is possible to variously adjust the degree of expansion of the cone and the degree of air mixing in the spiral water discharge form.

The flow rate of the washing water can be variously changed by adjusting the frequency and the duty ratio in the pulsating flow or the intermittent flow as described above, adjusting the pressure by a pressure adjusting valve, adjusting the flow rate by a flow adjusting valve, and the like. In this configuration, as the flow rate of the cleaning water increases, the swirling amount in the cleaning water vortex chamber 305 increases, and the air entrainment amount in the air entrapment chamber 301 also increases. As a result, the swirling diameter of the spiral water spout increases, the spread of the cone increases, and the cleaning area increases,
The particle size of water droplets at the time of water discharge becomes smaller. In other words, the cleaning water in the form of very fine water droplets is sprayed. Therefore, of the discharged washing water velocity, the straight component toward the human body part is relatively small, and the stimulation is weakened because it hits the human body part from an oblique direction. Furthermore, since the water droplets have a small particle size, a soft feeling is imparted.

That is, in the configuration of the present embodiment, if the pulsating flow is generated by the wave generator 25 to change the flow rate of the washing water, the degree of the spread of the cone in the spiral water discharge form can be improved. By changing the degree of air entrainment, the intensity of the stimulus given to the user can be changed periodically. However, when the flow rate of the washing water flowing into the washing water vortex chamber 205 is reduced, there is an element that the degree of the swirling of the washing water and the amount of air entrainment are reduced to enhance the sense of irritation,
There is also the opposite factor that the flow rate of the washing water itself decreases to reduce the feeling of irritation.

Therefore, when the above-mentioned swirling mechanism of the washing water is used, as shown in FIG. 20, the ass washing water passage 306 through which the washing water is discharged through the washing water vortex chamber 305, and the washing water separately from this. Another water passage 307 for discharging cleaning water from another water discharge hole 308 without passing through the vortex chamber 305 may be provided in parallel, and a supply destination of the cleaning water may be selected by a flow path switching valve (not shown). . As described above, the spiral cleaning water discharged from the throat through the cleaning water vortex chamber 305 has a small velocity component linearly traveling toward the local body part of the traveling speed, and therefore hits the local part obliquely. When you feel very soft. When air is mixed, the softness is enhanced by the action of the air bubbles. On the other hand, the cleaning water discharged from the water discharge hole 308 that does not pass through the cleaning water vortex chamber 305 travels substantially straight toward the human body local part, so that the stimulation when hitting the human body local part is relatively strong. Therefore, by periodically switching the flow path switching valve, it is possible to achieve a periodic change in the water discharge mode in which the mechanical stimulus changes.

Next, a modified example of the nozzle head 300 will be described. As shown in FIG. 21, this nozzle head 310 is, similarly to the nozzle head 300, a jet pump including an outside air entrapment chamber 301, an orifice 302, a tail water discharge hole 303 as a throat, and an outside air introduction passage 304. And a washing water vortex chamber 305 is provided below the orifice 302. Further, an eccentric path 306a eccentrically connected to the cleaning water vortex chamber 305 and a center directing path 306b connected to the cleaning water vortex chamber 305 so as to direct the center thereof are provided as nozzle water supply paths for the cleaning water. Further, a cleaning water supply unit (not shown) for supplying cleaning water independently to both paths is provided. This cleaning water supply unit is capable of supplying the cleaning water only to the center-directed path 306b and simultaneously supplying the cleaning water to both the center-directed path 306b and the eccentric path 306a. The flow rate is adjusted for each path. If the cleaning water is supplied from the cleaning water supply unit only to the eccentric path 306a, the nozzle head 30 described above is supplied.
Same as 0.

From the cleaning water supply unit to the center directing path 30
When the cleaning water is supplied only to the cleaning water 6b, the cleaning water flows into the cleaning water vortex chamber 305 in a direction near the center thereof. The washing water that has flowed in this way passes through the orifice 302 with little swirling in the washing water vortex chamber 305,
At the time of one passage, air is entrained and water is discharged from the throat.
In this case, the amount of outside air entrainment is reduced as compared with the case where the washing water is swirled in the washing water vortex chamber 305, and
The water spout does not spread in a cone shape, but becomes substantially cylindrical (FIG. 21).
F3 in the middle). For this reason, a relatively small washing area, which has a poor feeling of softness, is washed by a strong water force. It is irrelevant to increase the feeling of irritation. You can also.

From the cleaning water supply unit to the center directing path 30
Even when the cleaning water is supplied to both the 6b and the eccentric path 306a, if the flow rate Q1 of the center directing path 306b and the flow rate Q2 of the eccentric path are Q1 >> Q2, substantially the same result is obtained. .

On the other hand, when the cleaning water is supplied from the cleaning water supply unit to both the central directional path 306b and the eccentric path 306a, the flow rate Q1 of the central directional path 306b and the flow rate Q2 of the eccentric path 306a are appropriately set. Specifically, when Q2 >> Q1, the large amount of cleaning water supplied into the cleaning water vortex chamber 305 through the eccentric path 306a controls the behavior in the cleaning water vortex chamber 305. Therefore, as described above, the cleaning water swirls in the cleaning water vortex chamber 305, and the cleaning water containing a large amount of air is discharged while spreading spirally as shown in FIG. 21 (see F1). Therefore, a soft water force can be obtained.

When the flow rate Q1 of the center directing path 306b and the flow rate Q2 of the eccentric path 305a are adjusted so that Q2 approaches Q1, the cleaning water from the eccentric path 306a affects the behavior of the cleaning water in the cleaning water vortex chamber 305. The effect is reduced. Therefore, although the washing water swirls in the washing water vortex chamber 305, the degree of the swirling is small. As a result, the amount of outside air involved is reduced, the spread of the cone is also reduced, and the cleaning area is reduced (see F2 in FIG. 21). That is, in the nozzle head 310, each of the paths 306a, 3
By appropriately adjusting the flow rate of the cleaning water supply from the cleaning water 06b to the cleaning water vortex chamber 305, it is possible to obtain a water discharge mode in which the air mixing amount, the water discharge water force, the cleaning area, and the softness are adjusted to various stages. Therefore, by periodically fluctuating the flow rate, it is possible to achieve a periodic change in the water discharge mode in which the mechanical stimulus changes.

In the above description of the plurality of embodiments, various modes of the water discharge form control means have been exemplified, but the water discharge form control means is not limited to this. For example, a plurality of tail water outlets are prepared, an independent water supply channel is provided for each water discharge hole or a plurality of water discharge hole groups, and water supply to the water supply channel is controlled independently. By this water supply control, by changing the number and position of the water discharge holes from which the cleaning water is actually discharged, the cleaning area and the cleaning position can be changed, and as a result, the intensity of mechanical stimulation can be achieved. Also, taking advantage of the fact that the nozzle itself can be moved, the separation distance from the water discharge hole to the human body part is periodically changed, thereby changing the flow rate at the moment when the washing water hits the human body part, and giving strength to stimulation. it can.

As described above, in the human body local cleaning apparatus according to the present invention, some form of the cleaning water discharged from the water discharge hole toward the human body, for example, the flow rate, flow rate, pressure,
Spatial volume ratio (air mixing ratio), washing area hit by washing water, distance from water outlet to human body part, angle when washing water reaches human body part, water when washing water consists of body of water Any material can be used as long as it can periodically change the size (particle size) of the lump. Of course, any one of these forms may be changed, but two or more may be controlled simultaneously.

As described above, it is desirable to take into account the specific rhythm (period) of the human body itself in order to enhance the blood circulation promoting effect due to the change of the warm / cool change and the form of water discharge.
In other words, the blood vessels usually relax and contract according to the heartbeat, so that, for example, if a warm stimulus and / or a mechanical stimulus is performed in accordance with the timing at which the blood vessels relax, the intensity of these stimuli becomes more remarkable. It is thought that blood circulation can be promoted more effectively. In addition, there has been obtained a monitor research result that when a warm stimulus and / or a mechanical stimulus is performed in accordance with a respiratory cycle, some people relax their bodies.

Thus, as one method, a standard human body cycle or respiratory cycle related to relaxation / contraction of blood vessels such as blood flow, heartbeat, pulse, etc., is examined in advance, and the data is used as data by the controller 70. To be stored. Then, it is preferable that the warming / cooling cycle and the water discharge form cycle synchronized with the warming / cooling cycle be adjusted to the human body cycle. However, the human body cycle of the user may deviate from the standard human body cycle.
It is preferable that the adjustment can be performed in a predetermined range by the operation from Step 2. Further, if the phase relationship between the human body cycle and the heating / cooling cycle, the phase relationship between the heating / cooling cycle and the water discharge form cycle, etc. can be adjusted within a predetermined range, it is possible to further adjust the phase according to the user's preference. A comfortable state can be provided.

As another method, means for detecting a human body cycle or a respiratory cycle related to relaxation or contraction of blood vessels such as blood flow, heartbeat, pulse, etc., of a user sitting on a toilet seat, for example, a sphygmomanometer , A blood flow meter, or the like, and the control unit 70 may determine the heating / cooling cycle or the water discharge mode cycle based on the actually detected human body cycle. According to this, optimal control can be performed for each user. In such a configuration, since the physical information of the user can be recognized, parameters other than the warming / cooling cycle and the water discharge form cycle can be controlled using the information. For example, when the blood pressure is high, if the temperature difference at the time of hot / cold switching is too large, there is a possibility that the body will be adversely affected. Therefore, when the blood pressure is higher than a predetermined value, it is preferable to perform control such as reducing the temperature difference between the hot and cold alternation and reducing the range of the intensity of the mechanical stimulation. in this way,
By providing means for actually detecting or estimating the user's physical information, more precise and health-friendly washing can be performed according to the user's physical condition.

In the description of the above embodiment, since the control unit controls the hot / cold alternation and the change of the water discharge form, the synchronous relationship is not the main one and the other is the slave. However, for example, a detecting means for detecting a physical quantity such as a flow rate, a flow rate, a pressure, an air mixing amount, and a washing area of the washing water in a form of spouting water is provided, and the timing of the hot / cold replacement is determined based on the detection result by the detecting means. It may be. Alternatively, a detecting means for detecting the temperature of the wash water discharged on the contrary may be provided, and the timing of changing the water discharge form may be determined based on the detection result of the detecting means.

The above-described embodiment is merely an example, and it is apparent that changes and modifications can be made as appropriate within the scope of the present invention, in addition to the water discharge form control means. Specifically, for example, the following points can be changed.

In the above embodiment, the hot / cold switching is realized by switching the flow path of the heated washing water and the cooled washing water. However, by using a mixing valve with a variable mixing ratio,
The temperature can be controlled more precisely. Also, in the above embodiment, a cooling unit was used to obtain cold water,
If the temperature of the wash water supplied from the hydrant or the storage tank is sufficiently low, simply send the unheated wash water to the cold water flow path without providing a cooling unit. You may. However, in general, for example, in the summer season, the temperature of the original washing water itself often becomes high under the influence of the ambient temperature, and therefore, in order to always obtain a reliable thermal treatment effect, a cooling unit is provided. Is preferred.

Further, instead of switching between hot water and cold water, the temperature of the washing water may be changed by performing output control such as on / off control of a heater. In this case, the heater preferably has good response characteristics. For that purpose, it is desirable that the heat capacity is small and the heat conductivity is high, and a ceramic heater may be used, but a metal heater is preferable. In such a configuration, the flow path is simplified, and for example, it is possible to cope by changing only the temperature control program of the conventional human body local cleaning apparatus.

In the above description, the promotion of blood circulation in the buttocks has been described. However, if attention is paid to the fact that the effect of a hot and cold massage without a monotonous feeling can be obtained, the object to be washed is not limited to the buttocks but other washing areas, for example, It can also be applied to washing around the vagina, around the entrance of the urethra, etc. by bidet washing. Also, since the taste and the health condition of the washing feeling are different for each individual, for example, a personal key is provided in a remote controller (operation unit) so that the favorite condition can be registered, and immediately every time the apparatus is used, You may be made to be able to set to the favorite state.
