Embodiment 1
Hereinafter, embodiments of the present invention will be described in detail.

(Overview of humidifier)
As shown in FIG. 3, the humidifier according to the present invention includes a blower fan 2, a humidifying filter unit 3, and a water tank 4 inside a rectangular box-shaped housing 1. The interior of the housing 1 is divided into a rear suction chamber 1b and a front discharge chamber 1c by a partition wall 1a. The suction chamber 1b communicates with the outside through a large number of

air inlets

15, 15... Provided in the rear panel 14 of the housing 1, and the discharge chamber 1 c is an air supply established on the top plate of the housing 1. It communicates with the outside through the mouth 16. Further, the suction chamber 1b and the discharge chamber 1c communicate with each other through an opening 1d provided in the lower portion of the partition wall 1a.

As shown in FIG. 1, the rear panel 14 is detachable, and a deodorizing filter 17 and a dust collecting filter 18 are laminated on the front side of the rear panel 14. The deodorizing filter 17 is formed by, for example, dispersing and holding activated carbon in a nonwoven fabric, and acts to adsorb and remove odorous components in the air. The dust collection filter 18 is a known HEPA (HighＨEfficiency Particulate Air) filter, for example, and acts to collect and remove fine dust contained in the ventilation. The deodorizing filter 17 and the dust collection filter 18 are fitted in a filter chamber provided on the front side of the rear panel 14.

The blower fan 2 includes an impeller 20 and a fan motor 21 that drives the impeller 20. The fan motor 21 is fixed outside the discharge chamber 1c. The impeller 20 is fixed to the output end of the fan motor 21 projecting into the discharge chamber 1c, and is disposed so as to face the opening 1d below the partition wall 1a. The impeller 20 of the blower fan 2 is rotated by driving a fan motor 21. When the impeller 20 rotates, as indicated by white arrows in FIG. 3, outside air is introduced into the suction chamber 1 b through the

intake ports

15, 15... Provided in the rear panel 14. It flows forward in the suction chamber 1b and is sucked into the impeller 20 through the opening 1d at the lower part of the partition wall 1a. The direction is changed upward and led out into the discharge chamber 1c, and the air supply port at the end of the discharge chamber 1c. 16 and sent to the outside.

In this way, the suction chamber 1b and the discharge chamber 1c inside the housing 1 constitute the above-described air flow path in which the air flow is generated according to the operation of the blower fan 2. The deodorizing filter 17 and the dust collecting filter 18 are located on the upstream side of the air passage as described above, and the outside air introduced into the suction chamber 1b through the

intake ports

15, 15... Passes through the deodorizing filter 17. The odor component is removed by the above, and the air passes through the dust collection filter 18 to become clean air from which dust is removed, and is sent out through the air supply port 16 at the end of the discharge chamber 1c. The illustrated humidifier also functions as an air purifier due to the arrangement of the deodorizing filter 17 and the dust collecting filter 18.

The humidification filter unit 3 and the water tank 4 are arranged between the dust collection filter 18 and the blower fan 2 so as to humidify the air flowing through the air passage as described above.

The water tank 4 is a dish-shaped container having an open top, and is placed inside the suction chamber 1 b on the front side of the dust collection filter 18 by being fitted into a guide portion 19 provided on the bottom plate of the housing 1. As shown in FIG. 2, the water tank 4 is pulled out from one side surface of the housing 1 by sliding along the guide portion 19 together with the humidifying filter unit 3 supported on the water tank 4 as described later. It is possible. A wide tank receiver 40 is connected to the end of the water tank 4 on the drawer side, and a water supply tank 41 is attached to and detached from the tank receiver 40.

The water supply tank 41 is a rectangular parallelepiped tank having a water tap 42 at one end, and is mounted on the tank receiver 40 in an inverted posture with the water tap 42 side facing downward. The water tap 42 incorporates a known constant water level valve. When the water supply tank 41 is mounted on the tank receiver 40, the constant water level valve is pushed up by a push-up protrusion 43 (see FIG. 4) standing at a corresponding position of the tank receiver 40 to be opened and accommodated in the water supply tank 41. Water is sent out to the water tank 4 and acts to store water at a constant water level inside the water tank 4.

The humidifying filter unit 3 is configured by accommodating and holding a humidifying filter 31 inside a holding frame 30 having a hollow disk shape. That is, the holding frame 30 has a disk shape that rotates around the horizontal axis, and accommodates and holds the humidifying filter 131 therein. The humidifying filter 31 is composed of two detachable sheets made of a material such as a non-woven fabric that has a high water content and can be ventilated and can be washed. Details of the humidifying filter 31 will be described later.

FIG. 4 is a perspective view showing a support structure of the humidifying filter unit 3. In FIG. 4, only the holding frame 30 is illustrated, and the illustration of the humidifying filter 31 inside the holding frame 30 is omitted. FIG. 4 shows only a tank receiver 40 on one side of the water tank 4, and a water supply tank 41 attached to the tank receiver 40 is not shown.

As shown in FIG. 4, the humidifying filter unit 3 is supported in a posture in which the humidifying filter unit 3 stands vertically on the water tank 4 by placing the holding frame 30 on the two

support rollers

6 and 6 provided inside the water tank 4. Has been. The

support rollers

6 and 6 are rollers that rotate around the axis in the front-rear direction, are distributed on both sides in the longitudinal direction on the bottom surface of the water tank 4, and are in rolling contact with the outer peripheral surface of the holding frame 30 at each position. The humidifying filter unit 3 supported in this way can rotate around the central axis by the rolling of the

support rollers

6 and 6.

As shown in FIG. 2, the humidified filter unit 3 supported in this manner can be easily removed by pulling it out together with the water tank 4 from one side of the housing 1 and lifting it upward. Conversely, by inserting a part thereof into the water tank 4 and placing it on the two

support rollers

6, 6, it can be easily supported in the above-described posture. It can be pushed into the interior and set at a predetermined position inside the housing 1. Such attachment / detachment of the humidifying filter unit 3 is performed for maintenance and replacement of the humidifying filter 31 housed in the holding frame 30 and further for cleaning the inside of the water tank 4.

As shown in FIG. 4, a ring gear portion 32 having an appropriate width in which teeth are formed over the entire circumference is integrally provided on the outer peripheral surface of the holding frame 30. As shown in FIG. 3, the ring gear portion 32 is meshed with a transmission gear 51 of the drive unit 5 disposed above the holding frame 30.

The drive unit 5 includes a transmission gear 51 and a drive gear 52 attached to one surface of the base 50 and a drive motor 53 attached to the other surface of the base 50, and a plurality of fixing screws (see FIG. (Not shown) is fixed at an appropriate position of the partition wall 1a inside the housing 1. The drive gear 52 is fitted to the output shaft of the drive motor 53, and the rotation of the drive motor 53 is transmitted to the transmission gear 51 via the drive gear 52, and the transmission gear 51 rotates. .

The transmission gear 51 of the drive unit 5 and the ring gear portion 32 of the holding frame 30 mesh as shown in FIG. 3 when the humidifying filter unit 3 is set at the predetermined position described above. By this meshing, the humidifying filter unit 3 is supported at three points in different circumferential directions by the two

support rollers

6 and 6 inside the water tank 4 and the transmission gear 51 of the drive unit 5.

As shown in FIG. 3, the humidifying filter unit 3 supported in this manner is positioned so as to face the front side of the dust collection filter 18 and the rear side of the blower fan 2 inside the suction chamber 1 b, and the drive motor 53. When driven, the rotation of the drive gear 52 is transmitted to the holding frame 30 via the transmission gear 51 and the ring gear portion 32, and the humidifying filter unit 3 rotates around the central axis while maintaining the support position shown in FIG.

A circular support ring 33 is formed at the center of the rear surface of the holding frame 30 shown in FIG. 4 (the surface facing the dust collection filter 18) and the front surface opposite to the rear surface. A plurality of (six in the figure)

support ribs

34, 34... Communicating with the outer peripheral part are provided, respectively, and an arcuate closing part 35 is provided so as to close one part in the vicinity of the outer peripheral part.

The accommodation space of the humidifying filter 31 inside the holding frame 30 has a cross-sectional shape excluding the arcuate closing portion 35, that is, a cross-sectional shape in which a circular part is notched into an arcuate shape. The humidified filter 31 is held in a state of being supported from both the front and rear sides by the support ring 33 and the

support ribs

The water tank 4 stores water at a constant water level as described above. The lower part of the holding frame 30 that rotates as described above is immersed in the stored water of the water tank 4, and the stored water enters the holding frame 30 through the front and rear openings and is accommodated and held in the holding frame 30. Water is absorbed by the humidifying filter 31.

In the humidifier configured as described above, when the blower fan 2 is driven, the air flow described above is generated in the suction chamber 1b and the discharge chamber 1c in the housing 1, and the air is supplied to the holding frame 30 of the humidifying filter unit 3. Is introduced through the opening on the front surface, and is passed through the humidification filter 31 and sent out through the opening on the rear surface. When the drive unit 5 is driven, the humidifying filter unit 3 rotates, and as described above, the water stored in the water tank 4 is absorbed by the humidifying filter 31 in the holding frame 30 and lifted by the rotation of the holding frame 30. It spreads throughout the humidifying filter 31. Therefore, the air flowing as described above comes into contact with the humidifying filter 31 containing water, becomes humid air containing vaporized water, is sent out through the air supply port 16 at the end of the discharge chamber 1c, and passes through the room where the humidifier is installed. Humidify.

(Humidification filter)
Details of the humidifying filter 31 will be described below with reference to FIG.

The humidification filter 31 is mounted on a humidifier and is composed of two

sheet materials

11 and 12 as shown in FIG. Each of the

sheet materials

11 and 12 is made of a material (rayon, PET, etc.) that has high water content and can be ventilated, such as a non-woven fabric, and can be squeezed and washed. The attachment and detachment of the

sheet materials

11 and 12 is performed by attachment /

detachment members

13a and 13b provided at the respective peripheral portions. These

detachable members

13a and 13b may be any members as long as they can attach and detach the

sheet materials

11 and 12 with one touch such as Velcro (registered trademark) and hooks. In addition, (a) of FIG. 1 is the figure which made the back side of the

sheet materials

11 and 12 the front. Therefore, the

sheet materials

11 and 12 are pasted together by the

detachable members

13a and 13b with the back surfaces facing each other. Since the

laminated sheet materials

11 and 12 are difficult to be self-supporting because the materials are soft, they are supported by being held in a holding frame 30 that is a support.

The sheet material 12 has a circular shape as shown in FIG. 1A, but the sheet material 11 has a structure in which an end portion 11a is notched. Thereby, when the two

sheet materials

11 and 12 are bonded together, as shown in FIG. 1B, the sheet material 12 is partially exposed by the end 11a of the sheet material 11 on the sheet material 11 side. It becomes.

The humidifying filter 31 configured in this manner has a structure in which two

sheet materials

11 and 12 are stacked, but since there is no overlapping portion between the sheet material 11 and the sheet material 12 at one end 31a, The sheet material 11 and the sheet material 12 can be easily peeled off by inserting a finger into the one end 31a.

Further, the

sheet materials

11 and 12 may have different structures.

(effect)
The humidifying filter 31 can be easily separated into the

sheet materials

11 and 12 after being removed from the apparatus, and each of the humidifying filters 31 can be rinsed and washed, so that impurities attached to the

sheet materials

11 and 12 can be easily removed. it can. That is, the user can easily clean the humidifying filter 31.

In particular, since the

sheet materials

11 and 12 can be easily attached / detached by attaching / detaching

members

13a and 13b such as a magic tape and a hook, the front and back surfaces can be sufficiently washed.

In addition, since the

sheet materials

11 and 12 are supported by the holding frame 30 as a support in a state where they are bonded together, the

sheet materials

11 and 12 do not require much thickness and strength. That is, it is possible to use a soft material that can be washed by squeezing for the

sheet materials

11 and 12. Thereby, the impurities adhering to the humidification filter 31 can be sufficiently removed only by washing with water by washing the

sheet materials

11 and 12.

Further, the humidifying filter 31 has the end portion 11a of the sheet material 11 cut away, so that it is easy to determine which side is to be upwinded when the

sheet materials

11 and 12 are bonded together. Judgment can be made.

Further, since the

sheet materials

11 and 12 are detachably provided by

detachable members

13a and 13b such as velcro tapes and hooks provided at predetermined positions, the

sheet materials

11 and 12 can be easily positioned. can do.

Thereby, it is possible to eliminate a positional shift when attaching the

sheet materials

11 and 12 and an error in the mounting direction.

The

sheet materials

11 and 12 constituting the humidifying filter 31 may have different water absorption amounts. If it is made of the same material, the amount of water absorption with the sheet material 12 can be made different by cutting out the end portion 11a of the sheet material 11 as shown in FIG.

Further, the

sheet materials

11 and 12 may have the same shape (surface area), and neither of them may have a notch structure. In this case, the material of the

sheet materials

11 and 12 may be made different to make the water absorption amount different.

Further, when the

sheet materials

11 and 12 have the same shape (surface area) and are not cut out, the

sheet materials

11 and 12 are made of the same material, have different thicknesses, and different amounts of water absorption. Also good.

In this way, if the water absorption amount of the

sheet materials

11 and 12 is varied, in the humidification filter, even if the moisture of one sheet material is lost, the moisture of one sheet material remains, so that the humidification performance is greatly reduced. Can be eliminated.

Further, when the humidifying filter 31 is set in the humidifier, when the sheet material 11 is disposed on the downstream side and the sheet material 12 is disposed on the upstream side, the opening ratio of the sheet material 11 is made smaller than the opening ratio of the sheet material 12. . Here, the aperture ratio indicates the roughness of the nonwoven fabric constituting the sheet material. A large aperture ratio means that the eyes are rough, and a small aperture ratio means that the eyes are fine. Therefore, as described above, by making the opening ratios of the

sheet materials

11 and 12 different, the humidifying filter 31 collects a large amount of dust not only with the humidifying function but also with the upstream sheet material 12, and the sheet material. The dust collecting function of collecting dust contained in the air that has passed through the sheet 12 with the sheet material 11 is also achieved.

The humidifying filter 31 is held by the holding frame 30 (support) in a state where the

sheet materials

11 and 12 are bonded together. The holding frame 30 has a hollow disk shape, and accommodates and holds the humidifying filter 31 therein. For this reason, in order to clean the humidification filter 31, it is necessary to take out the humidification filter from the inside of the holding frame 30.

Note that the peripheral edges of the

sheet materials

11 and 12 may be bonded together by ultrasonic welding or the like. In that case, the

sheet materials

11 and 12 become hollow. The central portions of the

sheet materials

11 and 12 may also be bonded together by ultrasonic welding or the like. Further, when the

sheet materials

11 and 12 have a notch structure, the notch portion may be bonded by ultrasonic welding or the like.

In Embodiment 2 below, the structure of the humidifying filter 31 is used, and the humidifying filter 31 is not housed inside the holding frame 30 but is inserted into the humidifying filter 31. The structure that promotes the autonomy of the humidifying filter 31 will be described.

[Embodiment 2]
The following will describe another embodiment of the present invention. For convenience of explanation, members having the same functions as those described in the first embodiment are given the same reference numerals, and descriptions thereof are omitted.

As shown in FIG. 5A, the humidifying filter 31 according to the present embodiment includes a support body 60 that supports the

sheet materials

11 and 12 in a state where the two

sheet materials

11 and 12 are bonded together. I have. That is, as shown in FIG. 5B, the two

sheet materials

11 and 12 cover the support 60 in a bonded state.

The support 60 has a three-dimensional frame structure, and the interior 60a has a hollow structure. Thereby, since the surface area of the said humidification filter 31 can be expanded by covering the humidification filter 31 so that the support body 60 may be covered, a humidification effect can be heightened.

Moreover, since the humidification filter 31 is in a state of covering the support body 60, it can be easily detached from the support body 60.

In addition, when the humidifying filter 31 is set in the humidifier, when the sheet material 11 is on the downstream side and the sheet material 12 is on the upstream side, the opening ratio of the sheet material 11 is preferably smaller than the opening ratio of the sheet material 12. .

Note that the structure of the support 60 is not limited to the shape shown in FIG. 5A, and may be a shape that allows the humidifying filter 31 to be three-dimensionally maintained when the humidifying filter 31 is covered. Any shape may be used.

In addition, the inside 60a of the support body 60 is preferably a hollow structure so that air is allowed to pass through in order to vaporize water contained in the humidified filter 31 covered, but it may not be a hollow structure.

Furthermore, the inside 60a of the support body 60 may have a hollow structure, and the rotation center 31b of the humidified filter 31 covered may be opened. Using this opening, the humidifying filter 31 is rotated together with the support body 60.

[Embodiment 3]
Hereinafter, embodiments of the present invention will be described as follows. For convenience of explanation, members having the same functions as those described in the embodiment are given the same reference numerals, and descriptions thereof are omitted.

(Overview of humidification control)
In the present embodiment, unlike the humidifying filter 31 described in the first and second embodiments, as shown in FIG. 6, a humidifying filter 131 formed by folding a sheet material into a bellows shape is used.

In this embodiment, a humidifier having the same structure as in the first and second embodiments is used except that the humidifying filter 131 is used.

Since the humidifying filter 131 folds the sheet material in a bellows shape, a plurality of fold lines 131a are formed as shown in FIG.

Further, since the humidifying filter 131 absorbs water along the fold line 131a, the amount of water absorption varies depending on the angle formed between the direction in which the fold line 131a extends and the direction parallel to the water surface of the stored water in the water tank 4. For example, the angle formed between the direction in which the folding line 131a extends and the direction parallel to the water surface of the stored water in the water tank 4 is 90 ° in FIG. 6A, 180 ° in FIG. 6B, and FIG. (C) shows 45 °. FIG. 7 is a graph showing a change in the humidification amount with time when the rotation of the humidification filter 131 is stopped at the angle shown in FIG. Here, the air volume applied to the humidifying filter 131 is constant at 6.8 cm.

From the graph shown in FIG. 7, the amount of humidification is the largest when the angle formed by the direction in which the folding line 131a extends and the direction parallel to the water surface of the stored water in the water tank 4 is 90 °, and the most humidified when the angle is 180 °. You can see that the amount is small.

(effect)
From the above, the humidification filter 131 is adjusted by adjusting the angle formed by the direction in which the folding line 131a extends and the direction parallel to the water surface of the stored water in the water tank 4 (hereinafter referred to as the humidification control angle). It can be seen that the amount can be controlled.

For example, FIG. 8 is a graph showing the humidification control of the present embodiment, and FIG. 9 is a graph showing the conventional humidification control for comparison with FIG.

From the graph shown in FIG. 9, it can be seen that the fluctuation is large with respect to the indoor target humidity, and unnecessary humidification is often performed. Here, the air volume is assumed to be constant. In this case, when the target humidity is reached, the rotation of the humidification filter is stopped, but even if the rotation is stopped, the humidification does not stop immediately due to moisture contained in the humidification filter. Further, when the humidity falls below the target humidity, rotation of the humidifying filter is started, but it takes time until the humidifying filter contains water. As described above, in the conventional humidification control, even if the target humidity is set, there is a time for exceeding the target humidity or falling below the target humidity, and the humidity control cannot be performed appropriately.

On the other hand, it can be seen from the graph shown in FIG. 8 that the humidity is controlled with little fluctuation with respect to the target humidity in the room. Again, the air volume is constant. In this case, since the rotation of the humidification motor for rotating the humidification filter 131 can be kept to a minimum, noise due to the driving sound of the humidification motor can be reduced. And since rotation of a humidification motor is the minimum, the power consumption concerning the drive of the said humidification motor can be suppressed.

In addition, since the humidification amount is controlled only by adjusting the rotation angle of the humidification filter 131, the amount of wind applied to the humidification filter 131 may be constant. Since it is not necessary to increase or decrease more than necessary, it is possible to reduce noise caused by the fan for blowing air. For this reason, the noise at the time of the humidification driving | operation in a humidifier can be reduced significantly rather than the conventional machine.

Hereinafter, a humidification control mechanism for realizing humidification control by rotation control of the humidification filter 131 will be described.

(Humidification control device)
FIG. 10 is a diagram illustrating a humidifying filter unit support structure for realizing humidification control of the humidifier according to the present embodiment.

As shown in FIG. 10, the humidifier includes a position detector 7 that detects that the humidifying filter 131 is at a predetermined rotational position (the rotational positions shown in FIGS. 6A to 6C). . As shown by a two-dot chain line in FIG. 10, the position detector 7 includes a detector provided on the closing portion 35 of the holding frame 30 at an appropriate distance from the center to one side in the circumferential direction. It is configured to output a detection signal when it is in the uppermost lower position. The position detector 7 can be configured by a combination of a magnet as a detector and a proximity switch, for example.

The detection signal of the position detector 7 is given to a control unit (humidification control unit) 8 for operation control. A control unit 8 indicated by blocks in FIG. 10 is a computer including a CPU, a ROM, and a RAM, and gives an operation command to the drive unit 5 in accordance with a driving operation by a user, and performs an operation for driving and controlling them.

When the drive unit 5 is driven, the humidifying filter unit 3 rotates, and as described above, the water stored in the water tank 4 is absorbed by the humidifying filter 131 in the holding frame 30 and lifted by the rotation of the holding frame 30. It spreads throughout the humidifying filter 131. Accordingly, the air flowing as described above comes into contact with the humidifying filter 131 containing water, becomes humid air containing vaporized water, is sent out of the apparatus, and humidifies the room where the humidifier is installed. That is, the air flowing from one surface to the other surface of the holding frame 30 is brought into contact with the humidifying filter 131 that rotates together with the holding frame 30 including the water stored in the water tank 4, and humid air containing vaporized moisture is brought into the other surface side. To humidify the room where the humidifier is installed.

Here, the angle formed by the direction of the fold line 131a of the humidifying filter 131 and the direction parallel to the water surface L of the water stored in the aquarium is any one of (a) to (c) in FIG. Moreover, a desired humidification amount can be obtained by stopping the rotation of the humidification filter unit 3. By controlling the rotation angle of the humidifying filter unit 3, the humidification control in the room where the humidifier is installed can be performed. The rotation angle may be controlled not only by the control using the position detector 7 but also by the rotation time as long as it is a method for controlling to an appropriate amount of humidification, or by another method. Good.

Further, when the humidifier stops the humidification operation, the control unit 8 refers to the detection signal of the position detector 7 and stops driving the drive unit 5 at the timing when the detection signal is input. Thereby, the humidification filter unit 3 stops in the rotation position shown in FIG. This rotational position is the position where the detector provided in the closing portion 35 of the holding frame 30 as described above is at the lowest position on the rotational circumference of the holding frame 30, and the humidifying filter unit 3 is as shown in FIG. Most of the strings of the bow-shaped closing portion 35 are above the water level (inner water level L) of the stored water in the water tank 4 and stop in a posture inclined with respect to the water surface.

As described above, the humidifying filter 131 accommodated in the holding frame 30 has a fold line substantially parallel to the string of the arcuate closing portion 35, and when the humidifying filter unit 3 stops, the humidifying filter A fold line 131a which is a fold line of 131 is also inclined with respect to the water surface of the stored water, that is, the horizontal direction.

In FIG. 10, when the holding frame 30 is stopped, some of the strings of the closing portion 35 are below the surface of the stored water, but all the strings of the closing portion 35 are above the surface of the stored water. It is also possible to stop the holding frame 30 at the rotation position at which the rotation is performed. By doing so, there is no water suction of the humidifying filter 131 after the rotation is stopped, which is more effective.

Embodiment 4 below describes a configuration in which the humidifying filter does not come into contact with the stored water when the humidifying operation is not performed in the humidifier.

[Embodiment 4]
Another embodiment of the present invention will be described as follows. For convenience of explanation, members having the same functions as those described in the embodiment are given the same reference numerals, and descriptions thereof are omitted.

FIG. 11 shows a schematic configuration of the humidifying filter, (a) shows the humidifying filter 131 used in the third embodiment, and (b) shows the humidifying filter 231 of the present embodiment.

In the third embodiment, as shown in FIG. 11A, the humidifying filter 131 has the center of the circle as the center of rotation. However, in this embodiment, the humidifying filter 131 is humidified as shown in FIG. 11B. The filter 231 has a position shifted from the center of the circle as the center of rotation. When the rotation of the humidification filter 231 is stopped, the rotation center is such that the portion with the shortest distance from the rotation center to the end of the humidification filter 231 faces the water surface of the stored water, and the humidification filter 231 is It is formed in a position that does not immerse in the stored water.

That is, when the center of the circle is the rotation center as in the humidifying filter 131 of FIG. 11A, the string of the closing portion 35 is stopped when the holding frame 30 is stopped, as shown in FIG. If a part of the humidifying filter 131 is below the water level of the stored water, the humidifying filter 131 will not be immersed in the stored water, but if the retaining frame 30 is not formed with the closing portion 35, the humidifying filter 131 will be used. 131 is immersed in the stored water. In that case, a part of the humidifying filter 131 is cut so that the humidifying filter 131 is not immersed in the stored water after the rotation is stopped.

On the other hand, if the rotation center is a position shifted from the center of the circle as in the humidifying filter 231 in FIG. If the rotation of the humidifying filter 231 is stopped so that the short part is at the bottom, the humidifying filter 231 is not immersed in the stored water.

In the case of the humidifying filter 131 shown in FIG. 11A, the ring gear portion 32 formed on the outer peripheral surface of the holding frame 30 is rotated by meshing with the drive gear 52 (FIG. 10) of the drive unit 5. In the case of the humidifying filter 231 shown in FIG. 11 (b), the ring gear portion 132 is formed around the center of rotation instead of the outer peripheral surface of the holding frame 30, and meshed with the drive gear 52 (FIG. 10) of the drive unit 5. It is rotated by doing.

In addition, you may form the ring gear part 132 in the outer peripheral surface of the holding frame 30 of the humidification filter 231 shown in FIG.11 (b). In this case, the drive unit 5 itself shown in FIG. 10 is moved in the vertical direction to follow the rotation of the humidifying filter 231.

As described above, in order to prevent the humidification filter 231 from being immersed in the stored water after the rotation is stopped, a part of the humidification filter 231 is not cut and the rotation center of the humidification filter 231 is merely shifted from the center of the circle. Since the surface area is not reduced by cutting part of the humidifying filter 231, the humidifying performance is not lowered.

Moreover, since the rotation center of the humidifying filter is simply shifted, the humidifying filter can be produced more simply than cutting a part of the humidifying filter.

In the present embodiment, as illustrated in FIG. 11B, the example in which the rotation center of the circular humidification filter 231 is shifted has been described. However, the humidification filter may have an elliptical shape instead of a circular shape. Good.
