Description

  The present invention mainly relates to a humidifier that humidifies a room, and more particularly to a humidifier that is provided with a water-absorbing material in an air passage and blows and humidifies it as humid air by allowing external air to flow through it as it is or by heating.

  As for the humidifier, in addition to the vaporization type (natural evaporation type) using the air blowing function, the ultrasonic atomization type and the heating evaporation type using the heating function are common, but in the vaporization type and the ultrasonic type, various bacteria are present in the water. Even if it is, it is emitted without being sterilized and becomes unsanitary, and the heat evaporation method can be heat sterilized, but it takes time to generate steam and it is vaporized at room temperature to eliminate the increase in power consumption. There have also been proposed hybrid type humidifiers that take advantage of what is vaporized at high temperatures (for example, see Patent Documents 1 to 3).

  With reference to FIG. 2 showing the embodiment of the present invention, such a hybrid type humidifier includes a water storage part 3 for storing water 2 supplied from the water supply tank 1, and immersion water in the water storage part 3. A water absorbing material 4 that absorbs water, a blower 6 that blows external air 7 through the water absorbing material 4 and moist air 8 containing water absorbed therein, and blows out from the outlet 5, and the water absorbing material 4. And a heater 9 for heating external air.

  Thereby, when only the blower 6 is driven without energizing the heater 9, immediate humidification by normal temperature evaporation when air at room temperature passes through the water absorbing material 4 can be performed. When the heater 9 is energized and the blower 6 is driven, Since room temperature air is heated by the heater 9 and allowed to pass through the water-absorbing material 4, it is possible to perform instant humidification with heat sterilization and heat evaporation with less power consumption.

By the way, in making use of the hybrid function, the humidity in the room is detected, and the driving state of the blower 6 and the heater 9 is controlled based on the detected humidity, and both the blower 6 and the heater 9 are driven. Only the blower 6 is driven. It is desirable to perform operation control such as stopping both the heater 6 and the heater 9. For this purpose, the humidity sensor is provided at a position in contact with the suctioned outside air that is not heated by the heater 9 or humidified by the water absorbing material 4 (for example, Patent Document 4).
Microfilm of actual application No. 53-130435 (No. 55-46175) Japanese Patent Laid-Open No. 7-42978 JP 2002-162070 A JP 2003-056874 A

  However, the heater 9 needs to be located on the upstream side of the water absorbing material 4 as described in Patent Documents 1 to 3 in order to increase the humidification efficiency from the water absorbing material 4 to the suction outside air. Satisfying this, the arrangement in which the heater 9 is positioned on the most upstream side as in the case of Patent Document 3 for ventilation efficiency and the like is to simplify the ventilation path and make the entire humidifier compact. If the heater 9 is adopted as a configuration near the suction port, a humidity sensor is provided in the vicinity of the heater 9, and there is a problem of erroneous detection due to the heat effect from the heater 9 and a decrease in life. If the humidity sensor is disposed at a location that has nothing to do with the ventilation path as described in Patent Document 4, it cannot be positively contacted with the outside air in the space to be humidified and it is difficult to accurately detect the humidity. However, the electrical equipment part diffuses and the unity is poor and the whole is likely to increase in size.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a hybrid type humidifier in which a humidity sensor is located in the vicinity of a heating source, and it is easy to cope with the overall compactness and easily detect humidity.

  In order to achieve the above object, the humidifier of the present invention includes a water storage section that stores water supplied from a water supply tank, a water absorbing material that absorbs immersion water in the water storage section, and the water absorption section. It has a basic configuration including a blower that blows out air from the outlet as humid air containing water that is sucked into and absorbed from outside air, and a heating source that heats the outside air that flows through the water absorbing material. It exhibits a hybrid type humidification function.

This onset Ming humidifier, in particular, arranged a humidity sensor between the heating source and its upper blower located at the lowest portion, suction outside air by the blower along the heat source, as is passes through the humidity sensor unit It is a feature that was.

In such a configuration, the humidity sensor is located in the vicinity of the heating source and does not disperse as an electrical component or an arrangement device, or the suction outside air passing between the heating source and the blower passes and positively contacts it, It is possible to detect the humidity of the humidification target space in an environment where there is no influence of heating by the heating source or humidification by the water-absorbing material, and in which the heat influence from the heating source that is lowered by the suction outside air is suppressed. In addition, the dead space between the heating source and the blower above it becomes a space where a humidity sensor is arranged and sucked outside air can be exerted on it, from the heating source through the water absorbing material to the blower above the heating source and blown outside. The equipment layout and ventilation path to be put out are gathered in one place without extra space.

In this case, the drive motor and the humidity sensor of the blower are partitioned by a partition, and an inclined surface that collects the outside air sucked by the blower on the side of the humidity sensor is formed on the opposite side of the partition to the humidity sensor. ,
The arrangement that the drive motor of the blower faces the humidity sensor can prevent the heat influence from the drive motor to the humidity sensor by partitioning the partition wall, and the inclined surface formed by the partition wall sucks outside air from the intake port to the humidity sensor side. The amount of sucked outside air passing through the collecting humidity sensor unit can be increased.

In this case, the humidity data is taken in and humidified every predetermined time.
Accurate humidity detection by a humidity sensor and appropriate humidification control based on the humidity detection are performed at predetermined time intervals.

  Further objects and features of the present invention will become apparent from the following detailed description and drawings. In addition, each feature of the present invention can be used alone or in combination in various combinations as much as possible.

According to the humidifier of the present invention, to exhibit the humidification control to a hybrid function based on the detected humidity, not dispersed as the electrical unit or and placement equipment humidity sensor located in the heat source near the entire compact The air in the humidification target space is accurately controlled by positively contacting the outside air without the influence of heating by the heating source or humidification by the water absorbing material, and also by suppressing the heat influence from the heating source. Detected and reflected in humidification control.

In particular, since the humidity sensor is disposed using a dead space between the heating source and the blower on the heating source so that contact with the suction outside air can be achieved without any special space, the heating source passes through the water absorbing material from the heating source. The equipment arrangement and the ventilation path that reach the upper blower and blow out to the outside are gathered in one place without extra space, further contributing to the overall downsizing.

  In addition, the arrangement in which the drive motor of the blower faces the humidity sensor has no thermal effect from the drive motor to the humidity sensor, and the humidity is further increased by increasing the contact amount of the outside air sucked from the intake port with the humidity sensor. Make sure it can be detected accurately.

  Hereinafter, the humidifier according to the embodiment of the present invention will be described in detail with reference to FIG. 1 to FIG. 4 for the understanding of the present invention.

  The humidifier shown in FIGS. 1 to 3 of the present embodiment includes a water storage unit 3 that stores the water 2 supplied from the water supply tank 1 described above as shown in FIG. 2, and the immersion water in the water storage unit 3. The water absorbing material 4 that absorbs water 2, the blower 6 that blows the external air 7 through the water absorbing material 4 and the moist air 8 containing water absorbed in the water absorbing material 4 and blows out from the outlet 11, and the water absorbing material 4. It has a basic configuration including a heater 9 for heating the external air 7 and exhibits a hybrid type humidification function. A water absorbing material 4 and a water supply tank 1 for absorbing water from a heater 9 and a water storage part 3 as shown in FIGS. 1 and 2 from one end part to the other end part along an elongated bottom part 12 as shown in FIG. A water supply unit 13 that is placed from above and that supplies water to the water storage unit 3 is disposed, and the blower 6 is disposed within the approximate range of the height H of the water supply tank 1 above the heater 9 and the water absorbent 4. The suction outside air 7 by the blower 6 reaches the blower 6 through the heater 9 and the water absorbing material 4, and forms the ventilation path 14 blown out from the blower outlet 11.

  Thereby, only the water supply part 13 which mounts the heater 9, the water absorption material 4, and the water supply tank 1 in the elongate direction of the bottom part 12 is located, and the elongate planar form whose elongate direction dimension is small by the amount which the air blower 6 does not locate. None, and on the installation area S of the heater 9 and the water absorbing material 4, the water supply tank 1 having a simple form that satisfies the required capacity by contributing to the reduction of the plane space by an amount higher than the installation area S. The blower 6 is located by effectively utilizing the space S0 that is formed within the range of the height H, and the entire humidifier 21 rises from the elongated bottom 12 to substantially the same height, and the one end side and the other end side. And a small and flat shape having vertically long end faces 15 and 16. Moreover, the outside air 7 sucked by the blower 6 is efficiently ventilated along the ventilation path 14 through the heater 9 and the water absorbing material 4 with low resistance by the suction action of the blower 6, and is blown to the outside from the blower 6. Can do. Therefore, the whole humidifier 21 is gathered in a small and flat form, the planar occupied space is small and is not obstructive, and can be used in a gap furniture arrangement. Moreover, the outside air 7 sucked by the blower 6 is efficiently ventilated through the heater 9 and the water absorbing material 4 with low resistance, and noise and power consumption are reduced.

  In order to do this, the humidifier 21 includes a synthetic resin dish-shaped bottom member 22 and a blower 6, and covers the installation area S of the heater 9 and the water absorbing material 4 with the bottom member 22. The main body portion 24 combined with the cover portion 23 is provided, and a portion of the bottom member 22 that is not covered with the cover portion 23 is a tank placement portion 25 on which the water supply tank 1 is placed. As shown in FIG. 2, the bottom member 22 and the cover part 23 are joined by stamping and screwed at a plurality of locations (not shown). However, the main body 24 may be configured in any manner.

  The water supply unit 13 is fitted into the tank mounting unit 25 so that it can be taken in and out through the upper opening thereof, and is inserted into the main body unit 24 in front of the heater 9. The water supply tank 1 is connected to the tank connecting portion 26a facing the tank mounting portion 25 of the 26 so as to be detachable from above. The tank connecting portion 26a has an annular ridge 26b that fits with an annular ridge 1c on the outer periphery of the shoulder portion 1b having the water supply port 1a of the water supply tank 1, and is positioned at the same time as the tank 1 is received. There is a recess 26d that receives the water supply port 1a and a cap-type normally closed valve 27 that is detachably attached to the water supply port 1 and is connected to the water storage unit 3. The tank connection unit 26a is connected to the bottom of the recess 26d. A protrusion 26f that pushes the normally closed valve 27 of the water tank 1 is provided. Thus, when the water supply tank 1 is connected to the tank connection portion 26a, the normally closed valve 27 is opened, and the water 2 in the water supply tank 1 flows out from the water supply port 1a, flows into the water storage portion 3 from the recess 26d, and is stored. The There is no further outflow that reaches the upper end of the water supply port 1a in the mounted state and the water supply port 1a is blocked, and the water supply tank 1a is opened each time the water supply port 1a is opened due to the consumption of water 2 in the water storage unit 3. Water 2 is replenished from 1 to the water reservoir 3.

  When the water 2 in the water supply tank 1 is completely consumed, no more water 2 is supplied to the water storage unit 3 and the water level is lowered. This change in the water level results in a change in the height of the float 31 as shown in FIG. 2 installed in the water storage unit 3 and the water in the water storage unit 3 by a sensor 32 as shown in FIG. 2 such as a reed switch installed on the main body 24 side. 2 is less than a predetermined value, specifically, it is detected that the water 2 in the water supply tank 1 has run out, or the water 2 in the water storage section 3 has fallen below the predetermined water level, and the cover portion 23 of the main body portion 24 forms. The operation panel 33 that is positioned alongside the air outlet 11 on the top 24a is lit up and notified by voice. When the empty state of the water supply tank 1 is detected by the initial water level drop of the water 2 in the water storage unit 3 and notified, the water 2 is replenished by removing only the water supply tank 1 while continuing operation with the remaining water 2 in the water storage unit 3 It can be convenient. When the operation is stopped, the water storage section 3 can be removed from the main body section 24 and washed, so that it is easy to keep clean. In addition to a start key 35 for turning on and off the drive switch 34 as shown in FIG. 2 and a lamp 36 for lighting and displaying the operation state thereby, the operation panel 33 also turns on and off the heater 9 if necessary (not shown). Alternatively, it is possible to provide other operation keys and display units such as operation keys and display units for setting timers such as driving strength settings, driving reservations and driving durations. An operation board 136 for the operation and display is provided inside the operation panel 33. On the other hand, the control board 37 that drives the blower 6 and the heater 9 in response to the operation on the operation panel 33 is taken as an example between the blower 6 and the heater 9, that is, below the blower 6 and above the heater 9 and on the partition wall 40 or the shield 9. It is provided via a hot wall. A humidity sensor 38 is provided on the side of the intake port 41 of the control board 37. The control board 37 controls the driving state of the blower 6 and the heater 9 according to the detected humidity and adjusts the humidification level so that the set humidity is obtained. Adjust automatically. The humidity setting may be initially set or may be set by the user. Moreover, what is necessary is just to use an initial setting value, when there is no user setting.

In particular, as shown in FIGS. 2 and 3 , the humidity sensor 38 is arranged in the vicinity of the heater 9 as a heating source, and the humidity sensor 38 avoids the heater 9 before or after the suction air 7 by the blower 6 passes through the heater 9. I try to pass through the department. Accordingly, the humidity sensor 38 is located in the vicinity of the heater 9, that is, upstream or in the vicinity of the outer periphery of the heater 9, and the heater 9, the blower 6, the operation board 136, and the control are provided as one of the electrical component or the arrangement device. It does not disperse with other electrical components such as the substrate 37 or the arrangement equipment, and before passing through the heater 9 or through the suction outside air 7 avoiding the heater 9 and actively contacts with it, heating by the heater 9 or water absorbing material The humidity of the humidification target space 101 can be detected in an environment in which the influence of the heat from the heater 9 that is lowered by the suction outside air 7 is suppressed without being influenced by the humidification by 4. Therefore, in order to perform the humidification control based on the detected humidity and exhibit the hybrid function, the humidity sensor 38 is positioned in the vicinity of the heater 9 and is not dispersed from the other as one of the electrical equipment and the arrangement equipment, and the main body 24 This contributes to the overall compactness of the cover portion 23 and contributes to the overall compactness, and is positively brought into contact with the outside air 7 that is not affected by the heating by the heater 9 and the humidification by the water absorbing material 4, and the heat from the heater 9 The influence is also suppressed, and the humidity of the humidification target space 101 is accurately detected and reflected in the humidification control.

  Further, the humidity sensor 38 is arranged between the heater 9 located at the lowermost part of the main body 24 and the blower 6 on the heater 9 so that the outside air 7 sucked by the blower 6 passes through the humidity sensor 38 together with the heater 9. The dead space DS between the heater 9 and the blower 6 on the heater 9 is a space in which the humidity sensor 38 is arranged and the suction outside air 7 can be extended to the heater 9. The device arrangement and the ventilation path that blows to the outside of the fan 6 are gathered in one place without extra space, further contributing to the overall compactness.

  Further, as shown in FIG. 2, the drive motor 6 d and the humidity sensor 38 of the blower 6 are partitioned by a partition wall 102, and the suction outside air 7 by the blower 6 is placed on the side of the humidity sensor 38 on the opposite side of the partition wall 102 from the humidity sensor 38. An inclined surface 102a is formed. Thereby, as a compact arrangement in which the drive motor 6d of the blower 6 is opposed to the humidity sensor 38, the heat influence from the drive motor 6d to the humidity sensor 38 can be prevented by the partition 102, and the inclined surface 102a formed by the partition 102 can be prevented. Humidity can be detected more accurately by collecting the sucked outside air 7 from the intake port 41 on the humidity sensor 38 side and increasing the amount of the sucked outside air 7 passing through the humidity sensor 38 part. Moreover, the humidity sensor 38 and the heater 9 are also partitioned by the partition wall 40, and the thermal effect from the heater 9 to the humidity sensor 38 is further prevented by the partition wall 40.

  From the above, the heater 9 and the humidity sensor 38 are located inside the intake port 41 and come into contact with the outside air 7 immediately after the suction, so that the humidity of the humidification target space 101 can be more accurately determined without any other influence. Can be detected. The humidity sensor 38 in the illustrated example is further positioned on the upstream side of the heater 9 and on the heater 9 and faces the safety gap 103 between the heater 9 and the intake port 41 shown in FIG. As a result, the humidity sensor 38 can be exposed to the sucked outside air 7 passing to the heater 9, and in some cases, such ventilation can be blocked by the partition wall 40 or the like. Of course, the mounting portion of the humidity sensor 38 is positioned in the passage of the suction outside air 7 in the control board 37, but most of the control board 37 is positioned avoiding the ventilation path 14 including the ventilation portion to the humidity sensor 38. In order to do this, it is convenient to use a partition or a cover.

  Here, the humidity data detected by the humidity sensor 38 is captured after a non-heating operation or a low heating operation for a predetermined time, and humidification control is performed based on the captured humidity data. As a result, the humidity detected by the humidity sensor 38 does not deviate by the amount that the air in the humidification target space 101 can be agitated by the operation for a predetermined time, and the humidity sensor 38 from the heater 9 if the operation is performed without heating. The heat effect on the humidity sensor 38 can be avoided because the temperature of the heater 9 can be lowered to about room temperature or close to it even in the low heating operation. The humidity of the target space 101 can be detected with the highest accuracy. Therefore, by taking in the humidity data and performing humidification control every predetermined time, accurate humidity detection by the humidity sensor 38 and proper humidification control based on the humidity sensor 38 are performed every predetermined time.

  In order to change the operation state depending on the detected humidity, for example, when the humidity is less than 50%, the heater 9 is turned on and the drive motor 6d is rotated at a high speed, and when the humidity is 50% or more and less than 58%, the heater 9 is turned on. When the humidity is 58% or more, the humidity in the humidifying target space 101 is kept in an appropriate range by stopping the heater 9 and the driving motor 6d when the humidity is 58% or more.

  A specific example of the humidification control as described above shown in FIG. 4 will be described. When the automatic operation starts, the low operation is performed for 3 minutes, and the humidity sensor 38 detects the humidity while continuing the low operation after 3 minutes. . Next, the detected humidity data is taken in and the operation pattern of A: high operation, B: low operation, and C: stop is continued for 30 minutes according to the humidity at that time, and the control is repeated every 30 minutes. When an operation or signal for terminating the operation is input while continuing the operation for 30 minutes, the operation is stopped and the control is terminated. Here, the humidity is detected after the non-heating operation is performed for a predetermined time simultaneously with the start of the automatic humidity control operation, and the heating amount or the rotation amount of the blower 6 is changed according to the detected humidity. However, since the humidity is not detected in the non-automatic humidity control operation, it is sufficient to set the mode in which both the heater 9 and the blower 6 are operated simultaneously with the start of the operation. In addition, after turning off the heater 9 and the blower 6 at a predetermined humidity or higher in the automatic humidity control operation, it is preferable to perform the non-heated low operation even when the humidity is reduced and the operation is restarted.

Furthermore, when the form of the humidifier 21 and the like of the present embodiment is described, the water absorbing material 4 for absorbing water from the heater 9 and the water storage part 3 from the one end part to the other end part along the elongated bottom part 12 described above, A water supply unit 13 for placing the water supply tank 1 from above and supplying water to the water storage unit 3 is sequentially arranged, and the height H of the water supply tank 1 on the installation area S of the heater 9 and the water absorbing material 4 is set. The blower 6 is arranged in a substantially range, and the outside air 7 sucked by the blower 6 from the suction port 41 provided in the lower part of the vertically long end face 15 on the one end side reaches the blower 6 through the heater 9 and the water absorbing material 4. The ventilation path 14 blown out from the blower outlet 11 is formed. Thereby, the suction outside air 7 from the intake port 41 provided in the lower part of the vertically long end face 15 on the one end side goes straight and passes through the heater and the water absorbing material 4, and the ventilation path 14 is a so-called one-stroke writing form. The ventilation efficiency is further improved, and the whole is easy to downsize and slim. In addition, in the illustrated example, there is no extreme forced bending path, and there are few changes in the direction, and the ventilation efficiency is higher.
The intake port 41 is provided at a position and a size that allow the suction outside air 7 to reach the control board 37 and the humidity sensor 38 and cool it, and the control board 37 and the humidity sensor 38 cooperate with the partition wall 40 and the like. This prevents a problem from occurring due to the heat effect from the heater 9. In some cases, a combination with a heat sink can be used in combination to further increase the temperature.

  Further, along the elongated bottom portion 12, from one end portion to the other end portion, a heater 9, a water absorbing material 4 for absorbing water from the water storage portion 3, and a water supply tank 1 are placed from above to supply water to the water storage portion 3. The water supply section 13 to be arranged is sequentially arranged, the blower 6 is arranged in the range of the height H of the water supply tank 1 on the installation area S of the heater 9 and the water absorbing material 4, and the longitudinal end face 15 of the one end section is arranged. The suction outside air 7 by the air blower 6 from the air inlet 41 provided at the lower part of the air reaches the air blower 6 through the heater 9 and the water absorbing material 4, and is provided on the one end side of the elongated top portion 24 a corresponding to the bottom portion 12. The ventilation path 14 blown out from the blower outlet 11 is formed. This further simplifies the ventilation path 14 for blowing the sucked outside air 7 from the blower 6 to the outside through the blowout port 11, thereby further improving the ventilation efficiency and reducing the size of the entire body including the main body 24 and the water supply tank 1. Easy to slim. Further, since the air inlet 41 and the air outlet 11 are located at one end side of the top portion 24a and the lower portion of the end surface 15 on the one end portion side, the external air Can be sucked and the humid air 8 can be blown out, and the humid air 8 blown out from the outlet can be prevented from being sucked in from the intake port 41. Therefore, the air inlet 41 and the air outlet 11 are located at one end side of the top 24a and the lower portion of the end face 15 on the one end portion side, and can be practically used without being blocked by the arrangement as gap furniture. It can be avoided that the humidified air 8 at the blowout port 11 is sucked to reduce the humidification efficiency.

  The blower 6 is a sirocco type in which the axial line is oriented in the elongated direction, the intake port 41 is directed to the other end side, and the discharge port 6 a is connected upward to the air outlet 11. The outside air 7 passes through the heater 9 toward the other end side in the elongated direction, reaches the water absorbing material 4, reaches the suction port 6b of the blower 6 upward from the water absorbing material 4, and is sucked toward the one end side. Then, the ventilation path 14 discharged from the upward discharge port 6a to the blower outlet 11 and blown outside is formed. Since the blower 6 is a sirocco type in this way, the presence of the casing 6c that houses the impeller 6e and a smaller diameter than the axial fan can be used, contributing to downsizing and slimming, and the axis is in the elongated direction. The simple ventilation path 14 on the plane in the elongated direction is easily realized. Since the drive motor 6d for driving the impeller 6e is located outside the casing 6c, the drive motor 6d is not exposed to the humid air 8 even if the blower 6 is located on the downstream side of the water absorbing material 4.

  In addition, the suction outside air 7 that has reached the water absorbing material 4 is directed upward by a rising wall 3 a that rises integrally from the water storage portion 3. In this way, the suction external air 7 that reaches the water absorbing material in a direction parallel to the bottom portion 12 is allowed to escape upward of the water absorbing material 4 by the integrated rising wall 3a that rises from the water storage unit 3 itself in which the water absorbing material 4 is immersed. It can guide smoothly without running away. The rising wall 3a is located at the boundary between the concave portion 26d and the water storage portion 3, and communicates the concave portion 26d side and the water storage portion 3 side with a communication hole 30 provided in a part of the base in the width direction. Water 2 can be supplied. The water absorbing material 4 is positioned and held so that it can be attached and detached by a water absorbing material receiver 71 as shown in FIG. Accordingly, the water absorbing material 4 can be stably used in the mounting position together with the water storage unit 3 and can be used easily. However, the water absorption unit 4 can be integrated with the water storage unit 3 as needed and can be taken in and out of the main body unit 24. It can be taken out of the bottle and handled and cleaned alone.

  The blower outlet 11 is provided on the inclined surface 24b inclined upward toward the one end part of the top part 24a, and the humid air 8 blown out from the blower outlet 11 on the one end part side, that is, a water supply tank. It becomes easy to turn to 1 side. Therefore, when the end face 15 on one end faces the wall or the like, the user feels effective when the blown damp air 8 from the one end is directed toward the other end where the user is located, that is, the water supply tank 1 side. It is possible to prevent the wet air 8 from touching the wall or the like and causing condensation. In addition, since the air outlet 11 has the guide vane 11a inclined upward on the other end portion side, the humid air blown from the air outlet 11 on the one end portion side is brought into the other end portion side, that is, the water supply tank 1 side. It is easy to give directivity to face.

  The guide vane 11a is integrally formed with a rotary frame 51 that is fitted to the outlet 11 so as to be able to rotate around its central axis, and the rotary frame 51 is rotated to direct the pointing direction of the guide vane 11a in any direction. In addition, it is possible to freely adjust the blowing direction of the humid air 8 from the outlet 11 according to the relationship between the installation position and direction of the humidifier and the wall, the relationship with the user's location, and the like. In particular, the guide blade 11a is opposite to the inclination shown in FIGS. 1 and 2 from the relationship between the inclination of the inclined surface 24b and the inclination of the guide blade 11a with respect to the rotation surface of the rotary frame 51 along this inclination. When the guide vane 11a is rotated in the direction, the guide vane 11a becomes a posture almost directly above, and the blown wet air 8 can be blown out right above. Moreover, even if the end face 15 faces a wall or the like in this state, it is possible to reduce the contact with the blown damp air. The rotating frame 51 is provided with two recesses 51a on the diameter line for rotating with a finger.

  Note that a part of the casing 6 c of the blower 6 is formed by sharing the cover wall of the cover portion 23. A handle 62 that can be raised and lowered by a shaft 61 is provided at the top of the water supply tank 1 to facilitate carrying. The handle 62 is stored in a storage recess 63 in the top of the water supply tank 1 in a prone state so as not to jump out to the top of the entire humidifier. Further, a gap 72 is formed between the cover portion 23 of the main body portion 24 and the water supply tank 1 using a draft when forming the body portion of the water supply tank 1 and a recess 73 on the cover portion 23 side. Although it is located on the side opposite to the tank 1, the heat from the heater 9 and the heat from the heated suction outside air 7 passing through the ventilation path 14 by the gap 72 reach the water supply tank 1 and expand the internal air. It is easy to prevent.
