Detailed Description

[ first embodiment ]

Hereinafter, an embodiment of the present invention will be described in detail. In the present embodiment, an example in which the air conditioner of the present invention is applied to a humidifier will be described. The air conditioner is not limited to the humidifier, and may be a dehumidifier, an air purifier having a dehumidifying function and/or a humidifying function, or the like. The dehumidifier includes a water storage tray similar to the water storage tray 2 described later and a storage unit similar to the storage unit 1a for storing water generated as a result of dehumidification. In addition, the water storage tray is constructed in a large capacity to store all water generated in dehumidification.

Therefore, the dehumidifier may have a configuration of a fan and a water storage tray similar to that of the humidifier 100.

The humidifier may be a vaporization type humidifier, or may be a type other than a vaporization type humidifier, for example, a steam (heating) type humidifier or an ultrasonic type humidifier.

(outline of humidifier)

Fig. 1 is a perspective view showing an external appearance of a humidifier 101 according to the present embodiment, where (a) is a perspective view showing a state where a back cover 7 is attached, and (b) is a perspective view showing a state where the back cover 7 is detached. Fig. 2 (a) is an AA-line cross-sectional view of fig. 1(a), and (b) is a BB-line cross-sectional view of fig. 1 (a). Fig. 3 is a perspective view of the main body 1 and the water storage tray 2 of the humidifier (air conditioner) 101 according to the present embodiment. In fig. 3, for the purpose of explaining the inside of the water storage tray 2, the storage section 1a other than the ceiling surface 1a2, which is the lower part of the main body 1, is not shown, and the upper part of the main body 1 and the water storage tray 2 are shown separately.

As shown in fig. 1, the humidifier 101 includes a main body 1 of the humidifier 101 and a water storage tray 2 provided at a lower portion of the main body 1. An exhaust port (air outlet) 11 and a water supply port 12 are provided on the upper surface of the main body 1. The exhaust port 11 is an opening for discharging air humidified inside the main body 1 of the humidifier 101. The water supply port 12 is an opening for supplying water to the water storage tray 2 disposed at a lower portion of the main body 1.

The air outlet 11 is provided on the front surface side (the side on which the operation panel and the like are provided, that is, the side on which the humidified air is guided from the water storage tray 2 to the formation surface (the other side surface of the main body) of the air outlet path 20 of the air outlet 11) of the humidifier 101, and is designed to discharge the humidified air to the front surface side of the humidifier 101. On the other hand, the water supply port 12 is provided on the back surface side of the humidifier 101 (the formation surface (one side surface of the main body 1) of the water supply path (the groove 13, the first water supply path 14, and the second water supply path 15) to the water storage tray 2 on the opposite side of the exhaust port 11) so as to be designed to supply water from the upper portion of the humidifier 101 to the water storage tray 2 provided at the lower portion of the humidifier 101. Thus, the water supply port 12 is not adjacent to the air discharge port 11. That is, the water supply port 12 is formed at a position not affected by the air discharged from the air outlet 11. Here, the position not affected by the air discharged from the air outlet 11 means a position where the water in the water injection is not scattered by the air discharged from the air outlet 11. Specifically, the position not affected by the air discharged from the air outlet 11 means a position where the water in the water supply does not contact the air discharged from the air outlet 11.

As shown in fig. 1(a), a rear cover 7 is detachably provided on the rear surface of the main body 1. When the rear cover 7 is removed, as shown in fig. 1 (b), the groove 13 formed to connect the water supply port 12 and the water storage tray 2 is exposed. Water injected from the water supply port 12 is injected into the water storage tray 2 via the tank 13. The exposed surface of the groove 13 is closed by attaching the rear cover 7 to the humidifier 101. Thereby, as shown in fig. 2 (a), a first water supply path 14 is formed from the water supply port 12 to the water storage tray 2. The first water supply path 14 communicates with a second water supply path 15 formed in the water storage tray 2 described later.

As shown in fig. 1 and 2, the water storage tray 2 is detachably stored in a storage section 1a provided in a lower portion of the main body 1 from a rear surface side of the main body 1. The storage section 1a is a space provided in the lower portion of the main body 1 and having a size enough to store the water storage tray 2. A handle portion 4 is provided below the front surface 2a of the water storage tray 2 (the surface exposed when the water storage tray 2 is stored in the storage portion 1 a). The handle portion 4 is recessed from the front surface 2a into the water storage tray 2. Thus, the user can pull out the water tray 2 stored in the storage section 1a in the direction of arrow P1 (the pull-out direction parallel to the installation surface of the humidifier 101) by holding the handle section 4, thereby detaching the water tray 2 from the storage section 1a, or can push in the water tray 2 detached from the storage section 1a in the direction opposite to arrow P1, thereby storing the water tray 2 in the storage section 1 a.

As described later, the handle portion 4 functions not only as a handle for moving the water storage tray 2 into and out of the housing portion 1a, but also as a handle for picking up the main body 1 in a state where the water storage tray 2 is housed in the housing portion 1 a.

As shown in fig. 2 and 3, the water storage tray 2 includes a case 3 as a container and a humidification filter 16, and the humidification filter 16 is provided in a recess for storing water surrounded by the case 3. The housing 3 may be made of a resin material, for example. Among the frame-like edges surrounding the recessed portion of the water storage tray 2, a surface opposing the top surface (second surface) la2 of the housing portion 1a when housed in the housing portion 1a is referred to as an upper surface (first surface) 3 a.

As shown in fig. 2, a second water supply path 15 is formed in the water storage tray 2, and the second water supply path 15 communicates with the first water supply path 14 in a state where the humidifier 101 is attached. Therefore, by supplying water from the first water supply path 14 to the second water supply path 15, the water fills the concave portion of the water storage tray 2.

The humidification filter 16 is a sheet of a material (nonwoven fabric or the like) having high water-containing property and being capable of ventilation. The air is sent into the water storage tray 2 from the air sending path 17 in the humidifier 101 through the lattice 25 provided on the top surface 1a2 of the storage section 1a, which is the outlet of the air sending path 17. Specifically, as shown in fig. 2 (a), the humidification filter 16 is provided in a state in which the lower portion thereof is immersed in the water storage tray 2 that stores a fixed amount of water. That is, the humidification filter 16 is provided in the water storage tray 2 so that air can pass through while contacting an upper portion (water absorption portion) that is not immersed in water. Therefore, the water contained in the humidification filter 16 is vaporized by the air contacting the humidification filter 16, and is discharged as humidified air from the exhaust port 11 to the outside.

Here, the height of the humidification filter 16 from the bottom surface of the recess of the water storage tray 2 is preferably equal to the height from the bottom surface to the upper surface 3a in the recess of the water storage tray 2, for example. Accordingly, by reducing the air that does not pass through the humidification filter 16 as much as possible, the air with the humidity appropriately controlled can be discharged from the exhaust port 11. Therefore, it is preferable that the height from the bottom surface inside the recess of the water storage tray 2 to the upper surface 3a is the same as the height of the humidification filter 16.

As shown in fig. 2 (a) and (b), the humidifier 101 is provided with an air blowing fan 18 for sending air into the air blowing path 17, and a motor 19 for driving the air blowing fan 18.

When the blower fan 18 is driven by the motor 19, the external air is introduced into the air blowing path 17 from the air inlet (not shown) of the humidifier 101, and the air is blown out from the air blowing path 17 to the water storage tray 2 through the lattice portion 25. In fig. 2 (b), the blower fan 18 is exemplified as a sirocco fan, but may be an axial flow fan.

As shown in fig. 2 and 3, the air from the air blowing path 17 is sent to the first area 21, which is a space in front of the humidification filter 16 in the water storage tray 2. Then, the air passes through the humidification filter 16 while contacting the humidification filter 16, passes through the humidification filter 16 of the water tray 2, passes through the second region 22 which is a space on the opposite side of the first region 21, and is sent out from the exhaust port 11 to the outside through the blowout path 20. Therefore, the humidification filter 16, the air blowing path 17, and the air blowing fan 18 constitute a humidification unit that humidifies the air using the water in the water storage tray 2. The air blowing path 17 and the air blowing fan 18 constitute an air blowing unit for vaporizing the water contained in the humidification filter 16.

As described above, in the humidifier 101 having the above configuration, the water supply path (the first water supply path 14 and the second water supply path 15) for guiding water from the water supply port 12 to the water storage tray 2 and the air blowing path (the air blowing path 17 and the air blowing path 20) for guiding the introduced outside air from the water storage tray 2 to the air outlet 11 are formed.

(Water supply route)

Next, a water supply path to the water storage tray 2 will be described. As described above, the water supply path is a path from the water supply port 12 to the second water supply path 15 via the first water supply path 14 as shown in fig. 2 (a) and 3. The first water supply path 14 is formed along the outer side surface of the air blowing path 17, and, as shown in fig. 1 (b), includes a rear cover 7 and a groove 13 exposed in a state where the rear cover 7 is removed. Preferably, the rear surface (the surface facing the groove 13) of the rear cover 7 and the surface of the groove 13 are subjected to fine unevenness (texturing) which exerts a lotus effect. This makes it difficult for dirt to adhere. Further, since the groove 13 is exposed when the rear cover 7 is removed, maintenance such as cleaning of the first water supply path 14 is facilitated.

As shown in fig. 2 (a) and 3, the second water supply path 15 is formed at an end portion of the water storage tray 2, and takes in water from a first opening portion 15a of a portion communicating with the first water supply path 14 and discharges water from a second opening portion 15b formed toward a lower portion of the water storage tray 2. Thereby, water is supplied from the bottom side to the water storage tray 2.

Further, it is preferable that the inner surface of the recess of the second water supply path 15 is also subjected to fine unevenness (texturing) which gives a lotus effect, similarly to the back surface of the rear cover 7 and the surface of the groove 13. This makes it difficult for dirt to adhere.

Further, it is preferable that the water supply surface of the water supply port 12 is also subjected to fine unevenness (texturing) which exhibits a lotus effect. This makes it difficult for dirt to adhere. Further, the water supply surface of the first water supply path 14 is preferably in a radiation reflecting surface shape so that water flows to the first water supply path 14. Thus, even if water is injected to any portion of the water supply surface of the water supply inlet 12, the water does not scatter and overflow to the outside, and the water flows appropriately to the first water supply path 14.

As described above, the water injected from the water supply port 12 is supplied to the water storage tray 2 through the first water supply path 14 and the second water supply path 15 constituting the water supply path. The water supplied from the water supply path flows into the first region 21 side of the water storage tray 2, and flows into the second region 22 via the humidification filter 16. That is, water is supplied from the side close to the air blowing path 17 to the side far from the air blowing path 17.

In general, the timing of supplying water to the water storage tray 2 may be when the water storage amount of the water storage tray 2 is equal to or less than a predetermined amount. For example, if the water storage amount in the water storage tray 2 is equal to or less than a predetermined amount, it may be notified to the user (by a sound notification, lighting of an LED, or the like) to promote the water supply. In order to detect the water storage amount of the water storage tray 2, a water level sensor may be provided in the main body 1.

(details of the storage tray 2 and the storage part 1a)

Fig. 4 is a plan view of the water storage tray 2 of the first embodiment. As shown in fig. 3 and 4, the water storage tray 2 is partitioned into a first area 21 and a second area 22 by the humidification filter 16 provided in the recess. The first region 21 faces the lattice portion 25 provided on the top surface 1a2 of the housing portion 1 a. The upper surface 3a of the water storage tray 2 surrounds the periphery of the recess of the water storage tray 2, that is, the periphery of the first region 21, the humidification filter 16, and the second region 22.

A first protrusion (first locking portion) 31 is provided on the upper surface 3a of the water storage tray 2, and the first protrusion 31 is shaped to protrude from the upper surface 3 a. In the present embodiment, the first protrusion 31 is provided directly on the upper surface 3 a. In the present embodiment, the first protrusions 31 are provided at two locations on the upper surface 3a with the recess of the water storage tray 2 interposed therebetween. In the example shown in fig. 3 and 4, two first protrusions 31 are provided on the upper surface 3a with the first region 21 interposed therebetween.

As shown in fig. 3, a second protrusion (second locking portion) 32 is provided on the top surface 1a2 of the storage section 1a facing the recess and the upper surface 3a of the water storage tray 2, and the second protrusion 32 protrudes from the top surface 1a 2. In the present embodiment, the second protrusion 32 is directly provided on the top surface 1a 2. In the example shown in fig. 3, two second protrusions 32 are provided on the top surface 1a2 with the lattice portion 25 interposed therebetween. The number of the first protrusions 31 and the second protrusions 32 is not limited to 2, and may be 1 or 3 or more. As described above, in the present embodiment, the first protrusion 31 and the second protrusion 32 are a combination of protruding shapes.

Fig. 5 is a side view of the water storage tray 2 in the state of being stored in the storage section 1a according to the first embodiment. Fig. 6 is a plan view of the water storage tray 2 shown in fig. 5. Fig. 6 shows a state in which the inside of the housing portion 1a is viewed through the ceiling surface 1a 2.

As shown in fig. 5 and 6, when the water storage tray 2 is stored in the storage portion 1a, the bottom surface 1a1, which is the installation surface in the storage portion 1a, contacts the back bottom surface of the water storage tray 2. The top surface 1a2 of the storage section 1a faces the recessed portion of the water storage tray 2 and the upper surface 3 a. When the user grips the handle portion 4 and takes out and puts the water storage tray 2 into the storage portion 1a, the water storage tray 2 slides in a state where the bottom surface 1a1, which is the installation surface of the storage portion 1a, is in contact with the back bottom surface of the water storage tray 2.

For example, a rail or the like as a mounting surface of the water storage tray 2 may be provided on a surface other than the bottom surface 1a1, such as a side surface in the housing portion 1 a. In this case, when the user takes out and puts the water tray 2 into the storage section la while holding the handle section 4, the water tray 2 slides on the guide rails in the storage section la in a state where the guide rails are in contact with the contact surfaces of the guide rails of the water tray 2.

As shown in fig. 3, 5, and 6, in a state where the storage section 1a stores the water tray 2, the second protrusion 32 is provided on the front side in the pull-out direction (the direction of arrow P1) with respect to the first protrusion 31. More specifically, as shown in fig. 6, the second protrusion 32 is provided on the top surface 1a2 so as to be on a path (a path shown by an arrow P31 in fig. 6) along which the first protrusion 31 moves when the water storage tray 2 is pulled out in the pull-out direction (the arrow P1 direction) from the state of being stored in the storage section la in a plan view.

As shown in fig. 5, the storage section 1a stores the water tray 2, and the distance between the upper surface 3a of the water tray 2 and the top surface 1a2 of the storage section 1a in a state where the bottom surface 1a1 of the storage section 1a is in contact with the back bottom surface of the water tray 2 is H1. Further, the distance from the upper surface 3a to the head top surface of the first protrusion 31 (the surface of the first protrusion 31 facing the top surface 1a 2) is set to the height H31 of the first protrusion 31, and the distance from the top surface 1a2 to the head top surface of the second protrusion 32 (the surface of the second protrusion 32 facing the upper surface 3 a) is set to the height H32 of the second protrusion 32.

Thus, the height H31 of the first protrusion 31 and the height H32 of the second protrusion 32 are smaller than the distance H1(H1> H31+ H32). In other words, the heights H31, H32 of the first protrusion 31 and the second protrusion 32 are as follows: when the water tray 2 is pulled out in the pull-out direction (the direction indicated by the arrow P1) in a state where the water tray 2 is in contact with the bottom surface 1a1, which is the installation surface of the water tray 2, in the storage section la, the water tray 2 is not in contact with each other (i.e., is not engaged with each other).

Fig. 7 is a side view showing a state where the back bottom surface of the water storage tray 2 stored in the storage section la on the front side in the drawing direction floats. When the user lifts the main body 1 of the humidifier 101, as shown in fig. 7, the user grips the handle portion 4 of the water storage tray 2 stored in the storage portion 1a and pulls out the water storage tray 2 in a direction (a direction indicated by an arrow P2) including a component vertically upward from the pulling-out direction (a direction indicated by an arrow P1). In this way, the back bottom surface of the water storage tray 2 stored in the storage section 1a on the front side in the pull-out direction floats from the bottom surface 1a1 which is the installation surface of the storage section 1 a. When the user further grips the grip portion 4 of the water storage tray 2 and applies a force in the direction indicated by the arrow P2, the first protrusion 31 provided on the upper surface 3a of the water storage tray 2 collides with (i.e., engages with) the second protrusion 32 provided on the top surface 1a2 of the housing portion 1 a. This is because, as described with reference to fig. 6, the second protrusion 32 is provided on the top surface 1a2 so as to be positioned on a path (a path indicated by an arrow P31 in fig. 6) along which the first protrusion 31 moves when the water tray 2 is pulled out in the pull-out direction (the arrow P1 direction) from the state of being stored in the storage portion 1a in a plan view.

As shown in fig. 7, by bringing the first projecting portion 31 into contact with the second projecting portion 32, even if the user holds the handle portion 4 of the water storage tray 2 and continues to apply a force in the direction indicated by the arrow P2, the user stops the drawing out from the storage portion 1a of the water storage tray 2. Then, when the user further grips the handle portion 4 of the water storage tray 2 from this state and continues to apply a force in the direction indicated by the arrow P2, the main body 1 floats vertically upward (in the direction indicated by the arrow PV). Thus, the user can lift the main body 1.

In this way, with the humidifier 101, when the user grips the handle portion 4 and pulls out the water tray 2 in the pull-out direction (the direction indicated by the arrow P1) in a state where the water tray 2 is brought into contact with the bottom surface 1a1, which is the installation surface of the water tray 2 in the housing portion 1a, the first protrusion 31 and the second protrusion 32 do not contact each other. That is, the first protrusion 31 and the second protrusion 32 are not engaged with each other. Thus, the user can hold the handle portion 4 and detach the water storage tray 2 from the housing portion 1 a.

When the user grips the handle portion 4, pulls out the water storage tray 2 in a direction (direction indicated by an arrow P2) including a component that is vertically upward relative to the pulling-out direction (direction indicated by an arrow P1), and pulls out the back bottom surface (contact surface with the bottom surface 1a1) on the front side in the pulling-out direction of the water storage tray 2 in a state where the back bottom surface is floated from the bottom surface 1a1 that is the installation surface of the water storage tray 2 in the housing portion 1a, the first protrusion 31 and the second protrusion 32 are in contact with each other. That is, the first protrusion 31 and the second protrusion 32 are engaged with each other. Thereby, the drawing-out of the water storage tray 2 is stopped. Therefore, even if the user holds the handle portion 4 and applies a force to the water storage tray 2 to lift the entire humidifier 101, the water storage tray 2 can be prevented from being detached from the housing portion 1a and the humidifier 101 can be prevented from falling. This can improve the practicality (ease of lifting) of lifting the humidifier 101.

Further, the handle portion 4 for pulling out the water tray 2 stored in the storage portion 1a and the handle portion 4 for lifting up the entire humidifier 101 can be shared, and it is not necessary to provide a handle for lifting up the entire humidifier 101 other than the handle portion 4 for pulling out the water tray 2 stored in the storage portion 1 a. In this way, since a space for lifting the entire humidifier 101 is not required, the humidifier 101 can be prevented from being enlarged.

Fig. 8 is a diagram showing the sectional shapes of the first protrusion 31 and the second protrusion 32 in the first embodiment, (a) is a diagram showing the positional relationship between the first protrusion 31 and the second protrusion 32 in a state where the back surface of the water storage tray 2 is in contact with the bottom surface 1al of the housing 1a, and (b) is a diagram showing the positional relationship between the first protrusion 31 and the second protrusion 32 in a state where the back surface on the front side in the pull-out direction of the water storage tray 2 floats on the bottom surface 1al of the housing 1 a.

As shown in fig. 8 (a), in the first projecting portion 31, an angle 31a formed by the head top surface and the side surface 31c on the pull-out direction front side is preferably a chamfered curved shape, not a right angle. Thus, when the water tray 2 stored in the storage section 1a is pulled out in the pull-out direction (the direction indicated by the arrow P1), even if the first protrusion 31 comes into contact with the second protrusion 32 for some reason, the first protrusion 31 is prevented from catching on the second protrusion 32, and the water tray 2 can be smoothly pulled out from the storage section 1 a.

In the first projecting portion 31, the corner 31b formed by the head top surface and the side surface on the rear side in the pull-out direction may be a right angle, but is preferably a curved shape chamfered from a right angle. Thus, when the water tray 2 is pushed in the pushing-in direction (the direction indicated by the arrow P3, the direction opposite to the arrow P1), even if the first protrusion 31 comes into contact with the second protrusion 32 for some reason, the first protrusion 31 is prevented from catching on the second protrusion 32, and the water tray 2 can be smoothly pushed in and stored in the storage section 1 a.

In the second projecting portion 32, a corner 32a formed by the head top surface and the side surface on the pull-out direction front side may be a right angle, but is preferably a curved shape chamfered from a right angle. Thus, when the water tray 2 is pushed in the pushing-in direction (the direction indicated by the arrow P3, the direction opposite to the arrow P1), even if the first protrusion 31 comes into contact with the second protrusion 32 for some reason, the first protrusion 31 is prevented from catching on the second protrusion 32, and the water tray 2 can be smoothly pushed in and stored in the storage section 1 a.

The angle θ 1 formed by the side surface 31c on the front side in the drawing direction of the first protrusion 31 and the upper surface 3a may be various angles, but it is particularly preferable that the side surface 31c is inclined so as to be smaller than 90 °. That is, the side surface 31c is preferably inclined from the upper surface 3a side to the head top surface side toward the front side in the pull-out direction. Thus, as shown by the broken line D in fig. 8 (b), when the user grips the handle portion 4 and lifts the water storage tray 2 in the direction indicated by the arrow P2, the side surface 31c of the first protrusion portion 31 is easily hooked on the side surface 32c of the second protrusion portion 32. This enables the user to more reliably and stably hold the handle portion 4 and lift the humidifier 101.

As shown in fig. 8 (a), the angle θ 2 formed by the side surface 32c of the second protrusion 32 on the rear side in the drawing direction and the top surface 1a2 may be any angle, but is particularly preferably 90 °. Thus, as shown by the broken line D in fig. 8 (b), when the user grips the handle portion 4 and lifts the water storage tray 2 in the direction indicated by the arrow P2, the side surface 31c of the first protrusion portion 31 is easily hooked on the side surface 32c of the second protrusion portion 32. This enables the user to more reliably and stably hold the handle portion 4 and lift the humidifier 101.

As shown in fig. 8 (a), in the second projecting portion 32, the corner 32b formed by the head top surface and the side surface 32c on the rear side in the pull-out direction may be a chamfered curved shape, but is preferably a right angle to the curved shape. Thus, as shown by the broken line D in fig. 8 (b), when the user holds the handle portion 4 and lifts the water storage tray 2 in the direction indicated by the arrow P2, the corner 32b of the second protrusion 32 is likely to be caught by the side surface 31c of the first protrusion 31. This enables the user to more reliably and stably hold the handle portion 4 and lift the humidifier 101.

Fig. 9 is a sectional view of the humidifier 101 according to modification 1, in the vicinity of the storage portion 1a in which the water storage tray 2 is stored, in the main body 1. In the humidifier 101 described with reference to fig. 1 to 8, a handle for lifting up the humidifier 101 may not be provided in addition to the handle portion 4 provided in the water storage tray 2. This reduces the space for installing the handle, and the entire device can be reduced in size.

In the example shown in fig. 9, the handle portion 1b1 is provided in the main body 1 in addition to the handle portion 4 provided in the water storage tray 2. The handle portion 1bl is provided at a position (front surface of the humidifier 101) symmetrical to the handle portion 4 of the water storage tray 2 accommodated in the accommodating portion la. The handle portion 1bl is recessed from the front surface of the humidifier 101 (i.e., the front surface of the main body 1). Thus, the user can hold the grip portion 4 provided on the water storage tray 2 and the grip portion 1b1 provided on the main body 1, and stably lift the humidifier 101.

The height (distance from the back surface of the main body 1) of the handle portion 1b1 provided on the main body 1 is preferably the same as the height of the handle portion 4 provided on the water storage tray 2. This enables the user to more stably lift the humidifier 101. In addition, the humidifier 101 of modification 1 may not be provided with a handle for lifting up the humidifier 101, other than the handle portion 4/1 bl. This reduces the space for installing the handle, and the entire device can be reduced in size.

[ second embodiment ]

A second embodiment of the present invention will be explained below. For convenience of explanation, members having the same functions as those described in the first embodiment are given the same reference numerals, and the explanation thereof will not be repeated.

Fig. 10 is a side view of the water storage tray 2 stored in the storage portion 1a provided in the main body 1 of the humidifier 101 according to the second embodiment. Fig. 11 is a side view showing a state where the back bottom surface of the water storage tray 2 stored in the storage section 1a on the front side in the pull-out direction is floated, according to the second embodiment.

As shown in fig. 10, the housing portion 1a may include a second recess (second locking portion) 32A instead of the second protrusion 32 (see fig. 5). In the present embodiment, the second recessed portion 32A is provided directly on the top surface 1a2 and is recessed from the top surface 1a 2. The second recess 32A has an area of a degree to which the first protrusion 31 is fitted. The positions and the number of the second recesses 32A are the same as those of the second protrusions 32 (see fig. 5).

As shown in fig. 10, the first protrusion 31 and the second recess 32A may have a combination of a protruding shape and a recessed shape. Thus, when the user grips the handle portion 4 and pulls out the water tray 2 in the pull-out direction (the direction indicated by the arrow P1) in a state where the water tray 2 is in contact with the bottom surface 1a1, which is the installation surface of the water tray 2 in the housing portion 1a, the first protrusion 31 and the second recess 32A do not contact each other. That is, the first protrusion 31 and the second recess 32A do not engage with each other. Thus, the user can hold the handle portion 4 and detach the water storage tray 2 from the housing portion 1 a.

As shown in fig. 11, when the user pulls out the water storage tray 2 in a direction (the direction indicated by an arrow P2) including a component vertically upward from the pulling-out direction (the direction indicated by an arrow P1) by holding the handle portion 4, the first protrusion 31 and the second recess 32A come into contact with each other when the back bottom surface (the surface in contact with the bottom surface 1a1) on the front side in the pulling-out direction of the water storage tray 2 is pulled out in a state of being floated from the bottom surface 1a1 which is the installation surface of the water storage tray 2 in the housing portion 1 a. That is, the first protrusion 31 and the second recess 32A are engaged with each other. In other words, the first protrusion 31 is fitted into the second recess 32A. Thereby, the drawing-out of the water storage tray 2 is stopped. Therefore, even if the user holds the handle portion 4 and applies a force to the water storage tray 2 to lift the entire humidifier 101, the water storage tray 2 can be prevented from being detached from the housing portion 1a and the humidifier 101 can be prevented from falling. This can improve the practicality (ease of lifting) of lifting the humidifier 101.

Further, the handle portion 4 for pulling out the water storage tray 2 stored in the storage portion 1a and the handle portion 4 for lifting up the entire humidifier 101 can be shared.

Fig. 12 is a side view of the water storage tray 2 stored in the storage portion 1a provided in the main body 1 of the humidifier 101 according to the modification of the second embodiment. As shown in fig. 12, the irregularities provided on the upper surface 3a of the water storage tray 2 and the top surface 1a2 of the storage section 1a may be reversed. In the example shown in fig. 12, the storage section 1A may be provided with the second protrusion 32 on the top surface 1A2 and the first recess (first locking portion) 31A instead of the first protrusion 31 on the upper surface 3a of the water storage tray 2 (see fig. 5). In the present modification, the first recess 31A is provided directly on the upper surface 3a and is recessed from the upper surface 3 a. The first recess 31A has an area of a degree to which the second protrusion 32 is fitted. The positions and the number of the first recesses 31A are the same as those of the first protrusions 31 (see fig. 5).

According to the configuration of fig. 12, when the user grips the handle portion 4 and pulls out the water storage tray 2 in the pull-out direction (the direction indicated by the arrow P1) in a state where the water storage tray 2 is in contact with the bottom surface 1A1, which is the installation surface of the water storage tray 2 in the housing portion 1A, the first concave portion 31A and the second convex portion 32 are not in contact with each other. That is, the first recess 31A and the second protrusion 32 are not engaged with each other.

Further, when the user pulls out the water storage tray 2 in a direction including a component vertically upward from the pull-out direction (the direction indicated by the arrow P1) by holding the handle portion 4, and pulls out the back bottom surface (the surface in contact with the bottom surface 1A1) on the front side in the pull-out direction of the water storage tray 2 in a state where the back bottom surface is lifted from the bottom surface 1A1, which is the installation surface of the water storage tray 2 in the housing portion 1A, the first concave portion 31A and the second convex portion 32 come into contact with each other. That is, the first recess 31A and the second protrusion 32 are engaged with each other. In other words, the first recess 31A is fitted to the second protrusion 32. Thereby, the drawing-out of the water storage tray 2 is stopped.

[ third embodiment ]

A third embodiment of the present invention will be explained below. For convenience of explanation, members having the same functions as those described in the first embodiment are given the same reference numerals, and the explanation thereof will not be repeated.

Fig. 13 is a side view of the water storage tray 2 of the third embodiment. As shown in fig. 13, the first protrusion 31B provided in the water storage tray 2 may be provided not on the upper surface 3a but on a side surface (first surface) 3c of the water storage tray 2. The side surface 3c is a surface parallel to the pull-out direction when the water tray 2 is pulled out from the housing portion 1 a. The first protrusion 31B protrudes from the side surface 3 c. The first protrusion 31B may be provided only on one side surface 3c of the two side surfaces 3c, but from the viewpoint of stability, it is preferable to provide the first protrusion 31B on each of the two side surfaces 3 c.

Fig. 14 is a plan view showing a side surface 1c of the housing portion 1a according to the third embodiment. For the sake of explanation, the side surface 1c is illustrated by a broken line. In the present embodiment, the guide rail 35 is provided on the side surface 1c of the housing portion 1a, and the guide rail 35 extends parallel to the direction in which the water tray 2 is pulled out. A side surface (second surface) 1c of the storage portion 1a is a surface facing the side surface 3c of the water tray 2 when the water tray 2 is stored. The guide rail 35 may be provided only on one side surface 1c of the two side surfaces 1c, but from the viewpoint of stability, it is preferable that the guide rail 35 be provided on each of the two side surfaces 1 c.

A second recess (second locking portion) 32B is provided on a lower surface 35a of the guide rail 35. In other words, in the present embodiment, the second recess 32B may be provided on the side surface 1c of the housing portion 1a with the guide rail 35 interposed therebetween.

Fig. 15 is a side view of the water storage tray 2 stored in the storage portion 1a provided in the main body 1 of the humidifier 101 according to the third embodiment.

As shown in fig. 15 and 16, in a state where the water storage tray 2 is stored in the storage portion 1a, the upper surface of the first protrusion 31B faces the lower surface 35a of the guide rail 35.

Further, in the guide rail 35, the second recessed portion 32B is provided forward in the pull-out direction with respect to the first projecting portion 31B in a state where the water storage tray 2 is stored in the storage portion 1 a. That is, the second recess 32B is provided so as to be located on a path along which the first protrusion 31 moves when the water tray 2 is pulled out in the pull-out direction from the state of being stored in the storage portion 1a in a plan view.

As shown in fig. 15, when the user grips the handle portion 4 and pulls out the water storage tray 2 in the pull-out direction (the direction indicated by the arrow P1) in a state where the water storage tray 2 and the bottom surface 1a1, which is the installation surface of the water storage tray 2 in the storage portion 1a, are set, the first protrusion 31 and the second recess 32B do not contact each other. That is, the first protrusion 31 and the second recess 32B do not engage with each other.

As shown in fig. 16, when the user pulls out the water storage tray 2 in a direction including a component vertically upward from the pull-out direction (the direction indicated by the arrow P1) by holding the handle portion 4, and pulls out the back bottom surface (the contact surface with the bottom surface 1a1) on the front side in the pull-out direction of the water storage tray 2 in a state where the back bottom surface is floated from the bottom surface 1a1 which is the installation surface of the water storage tray 2 in the housing portion 1a, the first protrusion 31 and the second recess 32B are brought into contact with each other. That is, the first protrusion 31 and the second recess 32B are engaged with each other. In other words, the first protrusion 31 is fitted into the second recess 32B. Thereby, the drawing-out of the water storage tray 2 is stopped.

Fig. 17 is a diagram showing a side surface 1c of the housing portion 1a according to a modification of the third embodiment. As shown in fig. 17, a through hole (second locking portion) 32C penetrating the guide rail 35 may be provided in the guide rail 35 instead of the second recess 32B. The through hole 32C is formed at the same position as the second recess 32B, and has an area of a degree that the first protrusion 31 is fitted. Even if the through hole 32C is provided in the guide rail 35 in this way, the same effect as in the case where the second concave portion 32B is provided in the guide rail 35 can be obtained.

The present invention is not limited to the above embodiments, and various modifications can be made within the scope shown in the claims, and embodiments obtained by appropriately combining technical means disclosed in the respective embodiments are also included in the technical scope of the present invention. Further, by combining the technical means disclosed in the respective embodiments, new technical features can be formed.
