FIG. 4 is an exploded perspective view showing the humidifying device according to the first embodiment of the present invention. As shown in FIG. 4, a front panel 41 and a pre-filter 42 are provided on the upstream side of the humidifying filter 12.

The pre-filter 42 is provided on the front panel 41 and plays a role of preventing dust and the like from entering the main body.

The front panel 41 is provided with an elastic hook 43 on the lower side surface.

The front panel 41 forms a part of the main body case 1 by being attached to the corresponding portion of the main body case 1 via the hook 43.

As shown in FIG. 4, the feature of the present embodiment is that the front panel 41, the pre-filter 42, the humidifying filter 12, the drain pan portion 16, and the water storage container 11 are detachable from the front surface of the main body case 1. ..

As described above, the water storage container 11 is provided with a tank portion 31 and a pump 17. In a general humidifier, scales and impurities contained in tap water adhere to the water channel. Further, dust and the like contained in the air are collected by the pre-filter, and minute dust that has passed through the pre-filter 42 adheres to the humidifying filter 12. That is, the pre-filter 42, the humidifying filter 12, the drain pan portion 16, the pump 17, the tank portion 31, and the water storage container 11 need to be regularly maintained.

By making these components removable from the front surface of the main body case 1, maintenance can be easily performed without moving the main body. That is, it improves the usability of the user.

The shape of the front panel 41 will be described in detail with reference to FIGS. 5 and 6.

FIG. 5 is a perspective view of the front panel 41 as viewed diagonally from the front right.

FIG. 6 is an exploded perspective view of the front panel 41 as viewed diagonally to the right from the rear.

When viewed from the front, the front panel 41 has an uneven shape composed of a plurality of wind upper surfaces 44 and wind lower surfaces 45. The wind upper surface 44 and the wind lower surface 45 have a certain distance, and the end faces thereof are composed of a connecting surface 46 or a slit 47. The presence of the connecting surface 46 ensures strength and makes the appearance beautiful. Air is taken into the main body from the slit 47 (suction port 7).

As shown in FIGS. 5 and 6, the connecting surface 46 may be provided on the same side (for example, the right side of the wind surface 44). In this way, the appearance is good and the strength can be sufficiently secured. When the front panel 41 is viewed from an angle as shown in FIG. 5, the slit 47 is a blind spot.

The pre-filter 42 includes a pre-filter frame 48 and a purification filter 49.

The pre-filter frame 48 is made of resin or the like, and is provided with a claw 50 for attaching to the front panel 41 and a pre-filter rib 51 extending in the leeward direction.

The purification filter 49 is made by processing a resin or the like into a fibrous form. The purification filter 49 is fixed by the pre-filter frame 48 by welding to the pre-filter frame 48 or the like.

The claws 50 are plate-shaped ribs extending in the vertical direction, and a plurality of claws 50 are provided at the upper end and the lower end of the pre-filter frame 48. The front panel 41 is provided with a horizontally long groove (not shown), and is fixed to the front panel 41 by inserting the upper and lower claws 50.

As shown in FIG. 6, the pre-filter 42 may be composed of two or a plurality of pre-filters 42. As a result, the size of each sheet is reduced, which facilitates handling when removing for maintenance. As a result, the usability of the user is improved.

As shown in FIG. 6, the pre-filter rib 51 is a rib extending in the horizontal direction near the center of the pre-filter 42. When the front panel 41 is incorporated in the main body case 1, the pre-filter rib 51 suppresses the deflection of the pre-filter 42 by coming into contact with the humidifying filter 12 on the leeward side of the pre-filter 42. When the pre-filter 42 is removed from the front panel 41 for maintenance or the like, the pre-filter rib 51 serves as a knob, so that the pre-filter 42 can be easily removed.

The operation of the hook 43 will be described. As shown in FIG. 7, the hook 43 is attached so as to hook the upper end portion of the front panel 41 to the upper end portion of the main body case 1, and a part of the hook 43 enters the main body case 1 to enter the front panel. 41 can be fixed. When removing the front panel 41, the hook 43 is pressed to release the hook from the main body case 1, and then the front panel 41 is pulled up in the direction of the arrow in FIG.

Here, the shape of the hook 43 will be described with reference to FIG. The hook 43 includes an elastic hook spring 52, a user-operated hook retainer 53, and a hook claw 54 that is hooked on the main body case 1. The hook spring 52 is incorporated inside the front panel 41, and the hook retainer 53 is configured to be exposed to the outer shell. When the user pushes the hook retainer 53, the hook spring 52 bends and the hook claw 54 moves inward (in the direction of the arrow), so that the hook with the main body case 1 is eliminated and the hook can be pulled out. Further, such a attachment / detachment mechanism by the hook 43 can also be applied to the water storage container 11.

With such a configuration, the height of the upper end of the front panel 41 and the height of the top surface of the main body case 1 are likely to match, and the appearance is improved. Further, since both ends of the front panel 41 can be held by both hands while the hook 43 is pressed and pulled up by both hands, the usability of the user is improved when the front panel 41 is removed.

(Embodiment 2)
The shape of the humidifying filter 12 will be described in detail.

FIG. 9 is a perspective view of the humidifying filter 12 as viewed from the windward side.

FIG. 10 is a perspective view of the humidifying filter 12 as viewed from the leeward side.

As shown in FIGS. 9 and 10, the humidifying filter 12 is composed of a filter frame 61 molded of resin or the like and a fibrous filter portion 62 having water absorption.

As shown in FIG. 10, there is an inflow portion 63 for supplying water in the upper part of the filter frame 61. In the present embodiment, the inflow portion 63 is provided on the leeward side of the filter frame 61, but may be provided on the upper end portion of the filter frame 61 instead of being provided on the leeward side of the filter frame 61.

FIG. 11 is a partial cross-sectional view of the II-II cross section of FIG. 9 as viewed from the direction of the arrow. As shown in FIG. 11, the filter unit 62 is composed of a plurality of filters 64 in the direction of the air passage 10 and is configured to supply water to the filter 64 on the windward side as represented by the water channel 65.

The air passing through the filter unit 62 passes while gradually increasing the humidity while depriving the filter unit 62 of water. That is, the air passing through the filter unit 62 has the lowest humidity when passing through the first layer filter 64 which is the most upwind, and passes through the filter 64 (the fourth layer in the case of FIG. 11) which is the most leeward. When you do, the humidity is the highest. That is, by supplying water to the filter 64 on the windward side, water can be supplied so as to compensate for the large amount of evaporation, so that humidification can be performed most efficiently. On the other hand, the filter 64 on the leeward side is sufficiently flooded by the action of blowing air. As a result, the filter unit 62 can be evenly flooded over a wide area, and the humidification performance can be improved.

Further, by forming the filter unit 62 with a plurality of layers of filters 64, one filter 64 can be made thin, so that maintenance becomes easy. In particular, since the filter 64 on the windward side has a large amount of moisture absorption and desorption, impurities contained in tap water and minute dust in the room are likely to accumulate. By configuring the filter unit 62 with a plurality of filters 64, only the windward filter 64 can be cleaned or replaced as needed. As a result, the life of the filter unit 62 can be improved.

As the plurality of filters 64 in FIG. 11, independent filters can be used for each layer.

Further, the filter 64 may be sewn into a cylindrical shape as shown in FIG. In FIG. 12, a four-layer structure is formed by using, for example, two cylindrical filters 64 instead of independent filters for each layer. FIG. 12 shows a state in which the filter unit 62 is removed from the filter frame 61 and viewed from the windward side (left side of FIG. 11). Since the tubular filter 64 has elasticity, it has a property of expanding in an elliptical shape as shown in FIG. 12 when it is removed from the filter frame 61. In reality, since the filter 64 is attached to the filter frame 61, the layers are connected without a gap as in the filter 64 of FIG.

The filter 64 of FIG. 12 uses a knitting method that is easily flooded in the lateral direction X. By sewing the filter 64 into a cylindrical shape, the water supplied to the first layer can easily be infiltrated into the second layer by utilizing the characteristic that the water is easily infiltrated in the lateral direction X. Further, the water supplied to the third layer is likely to be infiltrated into the fourth layer by utilizing the characteristic that the water is easily infiltrated in the lateral direction X. As a result, the humidification performance can be improved. Although two cylindrical filters 64 are used, one or a plurality of tubular filters 64 may be used.

FIG. 13 is an exploded perspective view of the filter frame 61. The filter frame 61 is composed of a leeward side filter frame 66 and a leeward side filter frame 67. With such a configuration, the filter portion 62 can be easily removed from the filter frame 61, and maintenance becomes easy. Further, the leeward side filter frame 66 and the leeward side filter frame 67 are provided with pins 68 extending toward the filter portion 62 at equal intervals. That is, the pin 68 of the leeward filter frame 66 extends in the leeward direction, and the pin 68 of the leeward filter frame 67 extends in the leeward direction. Since the pin 68 is configured to be pierced by the filter portion 62, the filter portion 62 can be held in a regular position without being displaced by its own weight.

Further, the leeward filter frame 66 is shallower than the leeward filter frame 67. That is, in the direction in which air flows, the thickness of the leeward filter frame 66 is smaller than the thickness of the leeward filter frame 67.

As described above, the windward filter 64 is easily soiled, but similarly, the windward filter frame 66 is also easily soiled. That is, by making the leeward side filter frame 67 which is hard to get dirty deep and the windward side filter frame 66 shallow, it is easy to handle the leeward side filter frame 66 which is easy to get dirty, and as a result, maintenance becomes easy.

Further, as shown in FIG. 10, the filter frame 61 is provided with the attachment / detachment detecting means 69. This is to stop the operation of the blower unit 3 and the pump motor 18 when the humidifying filter 12 is not attached to the main body case 1. This can be expected to have the effect of preventing water leakage by stopping the operation of the main body when the humidifying filter 12 removed due to maintenance or the like is forgotten to be attached or when it is not assembled correctly. As an example of the attachment / detachment detection means 69, it is composed of a magnet incorporated in the filter frame 61 and a sensor incorporated in the main body case 1 capable of detecting the magnet, and detects when the magnet and the sensor are separated by a certain distance or more. There is a configuration and so on.

As shown in FIG. 14, the lower end of the humidifying filter 12 is housed in the drain pan portion 16 (FIG. 4), and the upper portion is stopped by a movable stopper 70. The humidifying filter 12 can be switched between the fixed state and the released state by the stopper 70.

As shown in FIG. 10, the attachment / detachment detecting means 69 is preferably provided on the upper portion or the upper end portion of the filter frame 61. With such a configuration, when the humidifying filter 12 is not assembled correctly, the upper end portion of the humidifying filter 12 is most separated from the main body case 1, so that it is easy to detect attachment / detachment.

The attachment / detachment detecting means 69 is preferably provided on the upper portion or the upper end portion of the leeward side filter frame 67. Since the leeward side filter frame 67 has a thickness larger than that of the leeward side filter frame 66, it becomes easy to secure a space for providing the attachment / detachment detecting means 69.

As shown in FIG. 13, the lower part of the leeward filter frame 67 is provided with a drainage portion 71. This serves as an opening for collecting excess water from the filter unit 62 and flowing it out to the drain pan unit 16.

Further, the leeward side filter frame 66 and the leeward side filter frame 67 are provided with a filter grid 72 to hold the filter portion 62 so as not to fall off. The pressure loss is minimized by making the shape of the filter grid 72 of the leeward filter frame 66 and the shape of the filter grid 72 of the leeward filter frame 67 the same. As a result, improvement in humidification performance can be expected.

As shown in FIG. 11, the cross section of the filter grid 72 has a U-shape that is open to the outside and has protrusions on the inside. With such a shape, even if water droplets drip on the surface of the filter unit 62, it is difficult for water to leak to the outside of the filter frame 61, and it is possible to collect the water droplets on the filter unit 62 and the drainage unit 71. Become.

(Embodiment 3)
FIG. 15 is a partial cross-sectional view of the section III-III of FIG. 14 as viewed from the direction of the arrow.

As shown in FIG. 14, two sets of humidifying filters 12 may be provided and water may be supplied to each of them. When there are two sets of humidifying filters 12, the two supply units 15 are supplied from one pump 17, so that they need to be distributed in the water channel. In the present embodiment, the first supply unit 81 is provided in the middle of the water channel, and in the first supply unit 81, the water channel toward the humidifying filter 12 and the third pipe 83 (connection) toward the second supply unit 82 are provided. Branch to the hose). At this time, the first supply unit 81 and the second supply unit 82 are preferably set to the same height. This makes it possible to distribute the supplied water in a uniform amount without biasing to either side.

In the present embodiment, the third tube 83 uses a flexible material (for example, silicon). The third pipe 83 between the first supply unit 81 and the second supply unit 82 may be made convex downward by utilizing the weight of the third pipe 83. As a result, the lower end of the third pipe 83 is arranged at a position lower than that of the first supply unit 81. That is, in the first supply unit 81, the water supplied from the second pipe 20 can flow into the third pipe 83 by its own weight. As a result, water can be more evenly distributed to the first supply unit 81 and the second supply unit 82.

Further, it is preferable to use a flexible material also in the first pipe 19 (FIG. 2) and the second pipe 20 (FIG. 2) connecting the pump 17 to the first supply unit 81. As can be seen from FIG. 2, the pump 17 is located on the back side of the main body case 1, while the supply unit 15 is arranged on the front side of the main body case 1. By using a flexible material, the waterways can be arranged freely.

FIG. 16 is a cross-sectional perspective view of the IV-IV cross section of FIG. 15 as viewed from the direction of the arrow.

As shown in FIG. 2, the first back space portion 25 is divided into a blower portion 3 and a space 85 by a vertical wall surface 84. In the air passage 10, the space 85 is located upstream of the blower portion 3 and downstream of the humidifying filter 12.

As shown in FIG. 16, an ion generator 86 is provided on the wall surface 84 on the side of the blower portion 3. The ions described here are radicals that react with hydroxy groups (hydroxyl groups), are extremely unstable electrically, and have a very high oxidizing power because they try to take away the missing electrons from surrounding atoms and molecules. It is a strong one. This oxidizing action has the effect of decomposing odors and the like. When these ions are released into the room, the malodor in the room is decomposed, while when the space 85 is filled, the effect of suppressing the generation of the odor in the filter unit 62 can be obtained.

Specifically, as shown in FIG. 16, it is preferable that the wall surface 84 is provided with an attraction port 88 for attracting ions, and the ion generator 86 is provided at a position higher than the attraction port 88. .. The ion generator 86 and the attraction port 88 communicate with each other. Ions are released from the ion generator 86 into the space 85 as shown by the arrow of the attract air passage 89. When the blower unit 3 is operated, the attraction port 88 becomes a negative pressure, so that the ions generated from the ion generator 86 are sucked into the communication hole 90 and supplied to the room. Further, when the operation of the blower unit 3 is stopped, the space 85 can be filled with ions, and the filter unit 62 can be effectively exposed to the ions.

Explaining the attraction port 88 in more detail, the attraction port 88 opens downward and is provided at a position different from the communication hole 90 communicating with the air blowing portion of the wall surface 84 as shown in FIG. As a result, even if water is scattered from the humidifying filter 12, the water does not reach the ion generator 86. Therefore, the stability or safety of the humidifying device can be ensured.

Further, by providing the ion at a position different from the communication hole 90 communicating with the air blowing portion of the wall surface 84, it becomes difficult for ions to escape from the communicating hole 90 to the blowing portion 3. Therefore, it is effective in suppressing the odor of the filter unit 62.

As a result, the odor of the room and the filter unit 62 can be suppressed while ensuring the stability or safety of the humidifying device.

The water storage container 11 will be described in detail.

FIG. 17 is a perspective view of the water storage container 11.

FIG. 18 is a cross-sectional view of the VV cross section of FIG. 17 as viewed from the direction of the arrow.

The water supplied from the tank portion 31 is stored in the water storage container 11 during operation, and a constant water level 96 can be maintained. When the water in the tank portion 31 runs out, the water level 96 drops and can be detected by the drought detection device 97 inside the water storage container 11.

The feature of this embodiment is that the pump 17 is provided at a position lower than the detected water level of the drought detection device 97. That is, the drought can be detected while the pump 17 is covered with water. As a result, the pump 17 can be operated without sucking air. If the pump 17 sucks in air, there is a risk of shortening the life due to the generation of abnormal noise and the idling of the pump 17.

Further, by leaving water in the water storage container 11 and draining the residual water containing concentrated scale components and dirt, it is possible to improve the life of the main body.

(Embodiment 6)
FIG. 19 is a perspective view of the drain pan portion 16. The drain pan portion 16 is composed of a collecting portion 101 provided below or directly below the humidifying filter 12 and a guiding portion 102 communicating with the lower portion of the collecting portion 101, and a drain port 103 is provided at the lower end of the guiding portion 102. The excess water of the humidifying filter 12 reaches the recovery unit 101 by gravity. The excess water in the recovery unit 101 is sequentially guided to the induction unit 102 and the drain port 103, and is collected by the water storage container 11 arranged below the drain port 103.

The feature of this embodiment is that a hill portion 104 (FIG. 17) higher than the water level 96 during operation is provided in the water storage container 11, and excess water dripping from the drain port 103 falls on the hill portion 104. That's what I did. As a result, the distance from which the surplus water falls is shortened, and the surface on which the surplus water falls is not the water surface indicated by the water level 96, so that an effect of not generating a water drop sound can be obtained.

As described above, the filter portion 62 is made of a water-absorbent material and has a high water-retaining capacity. That is, the water is retained during or immediately after the operation. Since the water is gradually collected in the drain pan portion 16 by gravity, if the water storage container 11 is pulled out during or immediately after the operation, the water stored in the filter unit 62 cannot be collected in the water storage container 11.

In the present embodiment, as shown in FIG. 19, a stopper portion 105 having a rubber material is provided on the drain port 103 side. The stopper portion 105 operates to close the drain port 103 when the water storage container 11 is removed from the main body case 1, and opens the drain port 103 when the water storage container 11 is set in the main body case 1. Works on. That is, when the water storage container 11 is pulled out from the main body case 1, the water retained in the filter unit 62 can be temporarily stored in the induction unit 102 of the drain pan unit 16.

FIG. 20 is a partial cross-sectional view around the stopper portion 105. FIG. 20A shows a state in which the water storage container 11 is set in the main body case 1, and FIG. 20B shows a state in which the water storage container 11 is pulled out from the main body case 1. As shown in FIGS. 17 and 20 (a), the hill portion 104 has a hill rib 106 erected so as to surround the hill portion 104 in a part thereof. As shown in FIG. 20A, the upper end of the hill rib 106 is configured to extend to a position higher than the lower end of the stopper portion 105. As a result, when the water storage container 11 is set in the main body case 1, the stopper portion 105 can be pushed in conjunction with the water storage container 11 to open the drain port 103.

(Embodiment 7)
The configuration of the connecting unit 21 will be described in detail.

FIG. 21 is a partial cross-sectional view of the periphery of the connecting unit 21 when the water storage container 11 is attached to the main body case 1. The second connecting portion 23 is provided with a check valve 111 for damming the water in the second pipe 20. The check valve 111 has a configuration in which the second connecting portion 23 is opened when the water storage container 11 is attached (FIG. 21).

As shown in FIG. 22, when the water storage container 11 is pulled out, the second connecting portion 23 is closed by the effect of the check spring 112.

As a configuration for damming water, for example, a configuration such as the stopper portion 105 as shown in the sixth embodiment can be considered. In such a configuration, in order to supply water from the pump 17, it is necessary to open the stopper portion 105 widely and connect the first connecting portion 22. In such a configuration, the residual water of the second pipe 20 may leak to the outside of the main body case 1 while the stopper portion 105 is closed.

The feature of this embodiment is that the check mechanism is provided in the water channel. With such a configuration, when the water storage container 11 (first connecting portion 22) is pulled out, the second connecting portion 23 can be immediately closed by the check valve 111. As a result, the residual water in the second pipe 20 is less likely to leak.

23 and 24 are perspective views of the check valve 111.

As shown in FIG. 23, the check valve 111 is provided with a cross check rib 113 at the tip on the conical side having a shape in which a cylinder and a cone are combined. As shown in FIG. 24, the columnar side has a groove 114 on the annulus and a pin-shaped protrusion 115 at the center. The check spring 112 is inserted into the groove 114, and the protrusion 115 is inserted into the check spring 112. Note that the check spring 112 is not shown in FIGS. 23 and 24.

The check rib 113 is arranged on the side of the first connecting portion 22, and the check valve 111 can be stably pushed by the cylindrical first connecting portion 22. A groove 114 and a protrusion 115 are provided on the check spring 112 side, and the check valve 111 can be stably driven without the check spring 112 coming off. The first connecting portion 22 is incorporated in the water storage container 11, and when the water storage container 11 is set in the main body case 1, the first connecting portion 22 pushes the check valve 111 from the pump 17 as shown in FIG. The pumped water can be supplied to the second pipe 20.

The opening of the second connecting portion 23 is a hole having a diameter smaller than the diameter of the check valve 111, and the check valve 111 and the second connecting portion 23 come into contact with each other by the action of the check spring 112. An elastic material such as silicon is suitable for the second connecting portion 23.

(Embodiment 8)
As shown in FIG. 25, the water storage container 11 is provided with a water storage container handle 121.

FIG. 26 is a cross-sectional view of the VI-VI cross section of FIG. 25 as viewed from the direction of the arrow.

As shown in FIG. 26, the feature of this embodiment is that the tank 32 is provided below the water storage container handle 121. This makes it possible to increase the capacity of the tank 32.

FIG. 27 is a side view of the water storage container 11 with the water storage container handle 121 pulled up. The right side of the figure is the front side of the main body case 1.

The water storage container handle 121 can move from the state tilted toward the front side shown in FIG. 26 to the substantially vertical state shown in FIG. 27.

When the water storage container 11 is carried, the water storage container handle 121 may be pulled up vertically. In this case, when the water storage container 11 is set in the main body case 1, the water storage container handle 121 comes into contact with the lower part of the front panel 41. As a result, the water storage container handle 121 can be automatically retracted from the vertically pulled state as shown in FIGS. 25 and 26. In this way, the water storage container 11 can be conveniently set in the main body case 1.

FIG. 28 shows the operation when the tank portion 31 is set in the water storage container 11 step by step. The tank portion 31 is provided with a freely movable tank handle 36. The position of the shaft portion of the tank handle 36 is different from the center of gravity when the tank 32 is filled with water. That is, as shown in FIG. 28A, when the tank portion 31 is set in the water storage container 11, the tank 32 is configured to tilt downward toward the front side when the water is full.

Since there is a water storage container handle 121 on the front side of the tank 32, it is necessary to set the tank portion 31 so as to avoid the water storage container handle 121.

By configuring the tank 32 to tilt downward toward the front side when the tank 32 is full, the water storage container handle 121 can be positioned above the front side of the tank 32 when the tank portion 31 is set in the water storage container 11. .. The water storage container handle 121 is rotatably provided in the water storage container 11, and has a configuration in which the water storage container handle 121 is tilted to the front side (one side) of the water storage container 11 from a state in which the water storage container handle 121 is vertically pulled up. The water storage container 11 has a deep dish shape, and the upper end portion of the water storage container 11 on the back side (the other side) is arranged below the water storage container handle 121.

As a result, as shown in FIGS. 28 (a) → (b) → (c), the tank 32 can smoothly set the tank portion 31 in the water storage container 11 while avoiding the water storage container handle 121.

That is, due to the inclination of the tank 32 in the full state, the upper part on the front surface side of the tank 32 enters below the water storage container handle 121 (FIGS. 28 (a) → (b)).

Then, from the state of FIG. 28 (b), the bottom of the tank 32 comes into contact with the bottom surface of the water storage container 11, so that the tank 32 gradually shifts to the horizontal state (FIG. 28 (b) → (c)).

In this way, the user can correctly set the water storage container 11 without being aware of the mounting direction of the tank portion 31.

Further, as shown in FIGS. 29 (a) and 29 (b), the tank handle 36 is tilted to the front side (one side) and the back side (the other side) of the water storage container 11 in a state of being attached to the water storage container 11. The storage direction of the tank handle 36 may be front or rear.

As shown in FIG. 25, two sets of tank portions 31 may be provided. Since the tank 32 in the full water state has a considerable weight (in the present embodiment, the total water storage amount exceeds 10 liters), the burden of transportation becomes large. By providing two sets of tank portions 31, the weight of each tank portion 31 can be reduced, and the effect of reducing the transportation load can be expected.

As shown in FIGS. 17 and 18, a hill portion 104, a pump 17, a first pipe 19, and a first connecting portion 22 are arranged inside the water storage container 11.

As shown in FIGS. 29 and 30, the tank 32 has an asymmetrical shape. The upper right portion of FIG. 30 is a notch portion 122 that does not have the capacity of the tank 32.

When the tank portion 31 is attached to the water storage container 11, the notch portion 122 becomes a portion in which the hill portion 104 of the water storage container 11, the pump 17, and the like are accommodated. When the water storage container 11 with the tank portion 31 is attached to the main body case 1, the notch portion 122 becomes a portion in which a part of the drain pan portion 16, the second connecting portion 23, and the like are accommodated.

The feature of this embodiment is that the two tank portions 31 have the same shape, the notch portion 122 of one tank 32 has a hill portion 104, the notch portion 122 of the other tank 32 has a pump 17, and the first one. The pipe 19 and the first connecting portion 22 are provided. As a result, the tank 32 can be mounted on the water storage container 11 after securing a sufficient capacity while avoiding the components required for the water storage container 11.

By making the two tank portions 31 have the same shape, compatibility can be improved and usability can be improved.

Further, by securing a sufficient capacity of the tank 32, the frequency of water supply can be reduced and the convenience can be improved.

(Embodiment 9)
As shown in FIG. 1, a humidity detection hole 126 is provided on the side surface of the main body case 1.

FIG. 31 is a cross-sectional perspective view of the VII-VII cross section of FIG. 1 as viewed from the direction of the arrow.

As shown in FIG. 31, a humidity detection device 127 capable of detecting relative humidity is provided inside the humidity detection hole 126. The space where the humidity detection device 127 is located and the outside of the main body case 1 are communicated with each other by the humidity detection hole 126.

The position where the humidity detection device 127 is provided should not be affected by the moisture generated from the device and should be provided at a position where the temperature change is small.

When the air volume of the blower unit 3 is small or when the operation of the blower unit 3 is stopped, the moisture contained in the filter unit 62 is released from the suction port 7 (FIG. 2), causing moisture return to occur, and the suction port 7 The humidity in the vicinity may be higher than the humidity in the living room. On the other hand, when the air volume of the blower unit 3 is large, the temperature of the space 85 (FIG. 2) tends to be lower than room temperature due to the heat of vaporization of the filter unit 62.

The feature of this embodiment is that the humidity detection hole 126 and the humidity detection device 127 are provided on the back side (blower 3 side) of the wall surface 84 (FIG. 2) and on the upper part of the main body case 1.

That is, the humidity detection device 127 is located at a position that is not easily affected by the return of moisture from the suction port 7 and is not easily affected by the heat of vaporization. Further, by providing the upper part of the main body case 1, the airflow near the humidity detection hole 126 is less likely to stay, and the effect of preventing erroneous detection of the humidity detection device 127 can be expected.

Further, the humidity detection hole 126 partially communicates with the ion generator 86 and the attract air passage 89 (FIG. 16). With such a configuration, as shown by the arrow of the humidity attracting air passage 128 in FIG. 31, an air flow that takes in the air in the room is generated in the humidity detection device 127. As a result, it is possible to provide a humidifying device having high followability even when the humidity in the room changes. As a result, the effect of preventing erroneous detection of the humidity detection device 127 can be expected.

Although the humidifying device according to the present invention has been described above based on the embodiment, the present invention is not limited to the embodiment. As long as the gist of the present invention is not deviated, various modifications that can be conceived by those skilled in the art are applied to the present embodiment, and a form constructed by combining components in different embodiments is also included in the scope of the present invention. ..
