However, in a humidity control device such as the dehumidification/humidification device described in Patent Document 1, since the dehumidification tank and the humidification tank are each placed independently in the housing, water generated by dehumidification may mix into the water for humidification. Although this can be avoided, there has been a tendency for humidity control devices to become larger.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a humidity control device that can suppress the increase in size and can effectively arrange a dehumidification tank and a humidification tank.

According to one aspect of the present invention, a humidity control device includes a dehumidifying section, a first water receiving section, a first container, a humidifying section, a second container, and a housing. The dehumidifying section performs dehumidification. The first water receiving section receives first water generated by the dehumidifying section. The first container can receive the first water drained from the drainage position of the first water receiving section below the first water receiving section. The humidifying section performs humidification. The second container accommodates second water to be supplied to the humidifier. The housing accommodates the dehumidifying section, the first water receiving section, the first container, the humidifying section, and the second container. The second container is arranged inside the first container. The first water receiving section includes a positioning section that positions the second container along a pushing direction in which the first container is pushed into the housing.

An embodiment of a humidity control device 100 according to the present invention will be described with reference to FIGS. 1 and 2. 1 and 2 are perspective views showing a humidity control device 100 according to this embodiment.

As shown in FIG. 1, the humidity control device 100 is, for example, an air conditioner or a dehumidification/humidification device, and has at least a “dehumidification mode” and a “humidification mode”. "Dehumidification mode" indicates a mode for dehumidifying air. "Humidification mode" indicates a mode for humidifying air. The humidity control device 100 is, for example, a stationary type.

The humidity control device 100 includes a housing 10 , a dehumidifying section 20 , a first water receiving section 30 , a dehumidifying tank 50 , a humidifying section 60 , and a humidifying tank 70 .

The housing 10 includes a top plate 11 , a bottom plate 12 , a pair of side plates 13 , a front panel 14 , and a rear panel 15 . The bottom plate 12 corresponds to an example of "the bottom of the housing 10." The front panel 14, the rear panel 15, and the side plates 13 are each arranged between the top plate 11 and the bottom plate 12. A pair of side plates 13 are arranged to face each other. One of the pair of side plates 13 is provided with an insertion port 10b for inserting the dehumidification tank 50 into the interior 10a of the housing 10. The rear panel 15 is arranged to face the front panel 14. The top plate 11 is arranged to face the bottom plate 12. The top plate 11 is arranged above the housing 10. Hereinafter, in this specification, "above" or "below" indicates, for example, "above" or "below" along the vertical direction. The housing 10 accommodates a dehumidifying section 20, a first water receiving section 30, a dehumidifying tank 50, a humidifying section 60, and a humidifying tank 70.

The dehumidifier 20 performs dehumidification. Specifically, the dehumidifier 20 dehumidifies the air in the dehumidification mode. The dehumidifier 20 is, for example, a heat exchanger. Note that details of the configuration of the dehumidifying section 20 will be described later with reference to FIGS. 6 to 8.

The first water receiving section 30 receives the first water generated by the dehumidifying section 20. The first water receiving section 30 is, for example, a receiving tray member such as a drain pan for receiving water droplets. The first water is drained from the drain position 30a of the first water receiving section 30. The first water receiving section 30 includes a positioning section 36. The positioning unit 36 positions the humidification tank 70. Note that it is preferable that the humidity control device 100 further includes a second water receiving section 40 , and it is preferable that the first water receiving section 30 further includes a first hole 31 and a plug section 32 . The first hole portion 31 is arranged at the drainage position 30a of the first water receiving portion 30. The first hole portion 31 guides the first water to the second water receiving portion 40 . The plug portion 32 contacts the second water receiving portion 40 and opens the first hole portion 31 . Further, the plug portion 32 is separated from the second water receiving portion 40 and closes the first hole portion 31 .

The second water receiving section 40 is arranged in the dehumidification tank 50. The second water receiving part 40 is, for example, a lid-like member. The second water receiving section 40 has a hole 41. The second water receiving section 40 receives the first water from the first water receiving section 30 . The hole 41 guides the first water to the dehumidification tank 50.

The dehumidification tank 50 is below the first water receiving section 30 and can receive the first water drained from the drainage position 30a of the first water receiving section 30. When the second water receiving part 40 is arranged in the dehumidifying tank 50, the dehumidifying tank 50 accommodates the first water below the second water receiving part 40. The dehumidification tank 50 corresponds to an example of a "first container." The dehumidification tank 50 can be taken in and out of the housing 10. Specifically, the dehumidification tank 50 can be pushed into the interior 10a of the housing 10 from the outside. The interior 10a of the housing 10 shows a housing space for the dehumidification tank 50. Hereinafter, the direction D1 in which the dehumidification tank 50 is pushed into the interior 10a of the housing 10 may be referred to as the "pushing direction D1." The pushing direction D1 indicates a direction from the pair of side plates 13 where the insertion port 10b is provided to the side plate 13 where the insertion port 10b is not provided. The pushing direction D1 intersects the direction D2 from the front panel 14 to the rear panel 15. Hereinafter, the direction D2 from the front panel 14 toward the rear panel 15 may be referred to as a "front view direction D2." The negative direction along the Y-axis in the figure is an example of the pushing direction D1. The negative direction along the X-axis in the figure is an example of the front view direction D2.

The first hole portion 31 and plug portion 32 of the first water receiving portion 30 are arranged at a position closer to the back side of the interior 10a than the insertion opening 10b in the pushing direction D1.

The humidifier 60 performs humidification. Specifically, the humidifier 60 humidifies the air in the humidification mode. The humidifier 60 is, for example, a filter.

The humidification tank 70 accommodates second water to be supplied to the humidification section 60. The humidification tank 70 corresponds to an example of a "second container." Humidification tank 70 may be placed inside dehumidification tank 50. Note that details of the configurations of the humidifying section 60 and the humidifying tank 70 will be described later with reference to FIGS. 4 and 5.

As shown in FIG. 2, when the dehumidification tank 50 is pushed into the interior 10a of the housing 10 along the pushing direction D1 and accommodated, the dehumidification tank 50 is located inside the interior 10a of the housing 10. Hereinafter, the state in which the dehumidification tank 50 is located inside 10a of the housing 10 may be referred to as a "first accommodation state."

When the humidifying tank 70 is disposed inside the dehumidifying tank 50 and in the first accommodation state, the positioning section 36 positions the humidifying tank 70 along the pushing direction D1. In the first accommodation state, the positioning part 36 comes into contact with the humidifying tank 70 and humidifies in the direction D3 opposite to the pushing direction D1 until the drain position 30a of the first water receiving part 30 and the humidifying tank 70 are shifted from each other. Push the tank 70 back. Therefore, in the first accommodation state, the humidifying tank 70 moves in the opposite direction D3 from the draining position 30a of the first water receiving section 30 to a position that does not overlap with the position where it can receive the drained first water. Therefore, even if the dehumidifying tank 50 is placed below the first water receiving section 30 while housing the humidifying tank 70, the first water drained from the draining position 30a will mix into the second water in the humidifying tank 70. can be suppressed. As a result, the dehumidification tank 50 and the humidification tank 70 can be effectively arranged while suppressing the increase in size of the humidity control device 100.

Furthermore, in the first accommodation state, the plug part 32 of the first water receiving part 30 comes into contact with the second water receiving part 40 arranged in the dehumidifying tank 50, and the first hole part 31 of the first water receiving part 30 to open. The second water receiving part 40 receives the first water guided from the first hole part 31. The first water is then accommodated in the lower dehumidification tank 50 through the hole 41 of the second water receiving section 40 . Therefore, the operation of housing the dehumidification tank 50 into the casing 10 also serves as the operation of opening the first hole 31, and the force of the first water falling from the first water receiving section 30 to the bottom of the dehumidification tank 50 is reduced to a second level. This can be alleviated by the water receiving section 40. As a result, while storing the first water in the dehumidifying tank 50 in conjunction with the operation of storing the dehumidifying tank 50 in the housing 10, it is possible to reduce the sound of water. That is, when recovering the first water generated by dehumidification, it is possible to conveniently reduce the sound of water.

Next, details of the configuration regarding the dehumidification mode and humidification mode of the humidity control device 100 will be described with reference to FIG. 1 and further to FIGS. 3 to 8.

The humidifier 60 is housed in a humidifier tank 70. Specifically, one end of the humidifying section 60 is connected to the first wall 73, and the other end of the humidifying section 60 is connected to the third wall 75. The upper end of the humidifying section 60 is in contact with the gripping section 78 , and the lower end of the humidifying section 60 is in contact with the first bottom surface 71 . As a result, air passes through the humidifying section 60. Therefore, humidified air is released from the humidifier 60.

More specifically, as shown in FIG. 5, a humidification tank 70 may be placed inside the dehumidification tank 50. FIG. 5 is a perspective view showing the dehumidifying tank 50, the humidifying tank 70, and the humidifying section 60. Specifically, the shape of the humidification tank 70 is smaller than the shape of the dehumidification tank 50. The height of the first wall portion 72 of the humidification tank 70 is lower than the height of the second wall portion 52 of the dehumidification tank 50. More specifically, at least a portion of the outer circumferential surface of the wall of the humidifying tank 70 extends along at least a portion of the inner circumferential surface of the wall of the dehumidifying tank 50 . Specifically, the shape of the fourth wall 56 of the dehumidification tank 50 and the shape of the fourth wall 76 of the humidification tank 70 are similar in shape.

Next, a method for attaching the humidification tank 70 and the dehumidification tank 50 will be described in detail. The user places the first protrusion 59a in the first recess 79a, the second protrusion 59b in the second recess 79b, the third protrusion 59c in the third recess 79c, and the third protrusion 59c. The fourth protrusion 59d is arranged within the fourth recess 79d. The user moves the humidification tank 70 downward with respect to the dehumidification tank 50. When the humidifying tank 70 moves downward, the lower surface of the projecting portion 72a and the upper surface of the second wall portion 52 of the dehumidifying tank 50 come into contact. Therefore, downward movement of the humidifying tank 70 with respect to the dehumidifying tank 50 can be restricted. As a result, wobbling of the humidifying tank 70 with respect to the dehumidifying tank 50 can be suppressed.

The humidifying unit 60, the humidifying tank 70, and the dehumidifying tank 50 are integrally removable from the housing 10 (see FIG. 1). Specifically, the humidifying unit 60, the dehumidifying tank 50, and the humidifying tank 70 can be pushed into the interior 10a of the housing 10 in the pushing direction D1 in an integrated state. According to this embodiment, since the housing 10 only needs to have a single housing space, the humidity control device 100 can be further downsized. When the dehumidifying tank 50 is pushed into the interior 10a of the housing 10 with the humidifying tank 70 disposed inside the dehumidifying tank 50, the second leg portion 78c of the gripping portion 78 of the humidifying tank 70 becomes the first water receiving portion. It faces the positioning part 36 of 30. The second leg portion 78c comes into contact with the positioning portion 36 in the first accommodated state.

Next, the details of the configuration of the housing 10 and the dehumidifying section 20, as well as the operation of the humidity control device 100 in the dehumidifying mode and the humidifying mode, will be described. 6 to 8 are diagrams showing the inside of the humidity control device 100. Specifically, FIGS. 6 and 8 show the inside of the humidity control device 100 in the dehumidification mode. FIG. 7 shows the inside of the humidity control device 100 in humidification mode. In addition, in FIGS. 6 to 8, in order to avoid making the drawings excessively complicated and to make it easier to see the air flow in each mode, the details of the configuration of the first water receiving part 30 are omitted, and the details of the structure of the second water receiving part 30 are omitted. The configuration of the section 40 is omitted from the illustration.

The top plate 11 has an air outlet 11a, a cover member 11b, and an operation panel 11c. The air outlet 11a is an opening. The cover member 11b is a substantially plate-shaped member. The cover member 11b covers the air outlet 11a. The cover member 11b functions as a wind direction plate that defines the flow direction of the air discharged from the air outlet 11a. The operation panel 11c accepts instructions from the outside. Specifically, the operation panel 11c receives information indicating either dehumidification mode or humidification mode.

The housing 10 further includes a plurality of circulation parts 90 through which air circulates. Specifically, the plurality of flow sections 90 include a first chamber 91 , a second chamber 92 , a third chamber 93 , a fourth chamber 94 , and a fifth chamber 95 .

The first chamber 91 is arranged on the negative side of the X-axis of the housing 10 . The first chamber 91 communicates with the outside of the housing 10 via a plurality of suction ports 15a. The first chamber 91 has a filter 91a. The filter 91a is, for example, a deodorizing filter and/or a dust collecting filter.

The second chamber 92 is arranged on the positive side of the X-axis of the first chamber 91. The first chamber 91 and the second chamber 92 communicate with each other. The dehumidifying section 20 is arranged inside the second chamber 92. The dehumidifier 20 is driven in the dehumidification mode, as shown in FIG. 6, and is not driven in the humidification mode, as shown in FIG.

The third chamber 93 is arranged on the negative side of the Z-axis of the housing 10 . The first chamber 91 and the third chamber 93 communicate with each other. Inside the third chamber 93, a humidifying section 60, a dehumidifying tank 50, and a humidifying tank 70 are arranged. Specifically, the third chamber 93 has an accommodation space in which the dehumidification tank 50 and the humidification tank 70 are accommodated. Humidification tank 70 accommodates second water. The humidifier 60 performs humidification using the second water in the humidifier tank 70 . Specifically, as shown in FIG. 7, the humidification tank 70 is filled with second water in advance by the user during the humidification mode. As shown in FIG. 6, the humidification tank 70 is previously emptied by the user during the dehumidification mode. The dehumidification tank 50 accommodates the first water generated by the dehumidification section 20.

The fourth chamber 94 is arranged on the positive side of the X-axis of the housing 10 . Further, the fourth chamber 94 and the third chamber 93 communicate with each other. The humidity control device 100 further includes a blower section 80. The ventilation section 80 is arranged in the fourth chamber 94.

The fifth chamber 95 is arranged on the positive side of the Z-axis of the housing 10 . The fourth chamber 94 and the fifth chamber 95 communicate with each other. Further, the second chamber 92 and the fifth chamber 95 communicate with each other. Furthermore, the fifth chamber 95 communicates with the outside of the housing 10 via the air outlet 11a.

The dehumidifying section 20 includes an evaporator 21, a condenser 22, and a compressor.

Each of the evaporator 21 and the condenser 22 has a flow pipe through which a medium flows. The medium is, for example, a fluorocarbon. The material of the flow pipe is, for example, metal. The flow pipe of the evaporator 21, the flow pipe of the condenser 22, and the compressor are connected.

A compressor compresses a medium that is in a cold gaseous state to create a medium that is in a hot gaseous state. The compressor then delivers the medium, which is in the form of a hot gas, to the flow pipe of the condenser 22. The medium in a high-temperature gas state is liquefied while passing heat through the flow pipe of the condenser 22, and becomes a medium in a high-temperature liquid state. Additionally, the medium in the hot liquid state expands into the medium in the cold liquid state. A medium that is in the form of a cryogenic liquid is an example of a refrigerant. The medium in a low-temperature liquid state is vaporized while receiving heat in the flow pipe of the evaporator 21, and becomes a medium in a low-temperature gas state. The medium, which is in the cold gaseous state, is then compressed again in the compressor. In this way, the medium circulates between the flow pipes of the evaporator 21, the flow pipes of the condenser 22 and the compressor.

The evaporator 21 exchanges heat between air and refrigerant to remove water vapor from the air. Specifically, the flow pipe of the evaporator 21 is meandering within the second chamber 92 . The evaporator 21 further includes a plurality of metal plates between the flow pipes. As a result, air flows through the second chamber 92 while contacting the flow tube or metal plate. Therefore, the air transfers heat to the refrigerant, and the temperature of the air decreases. As a result, water droplets based on water vapor in the air adhere to the flow pipe or metal plate. Therefore, the evaporator 21 can effectively remove water vapor from the air.

The condenser 22 generates air at a predetermined temperature by exchanging heat between air and a medium in the form of a high-temperature gas. Specifically, the flow pipe of the condenser 22 is meandering within the second chamber 92 . Capacitor 22 further includes a plurality of metal plates between the flow tubes. As a result, air flows through the second chamber 92 while contacting the flow tube or metal plate. Therefore, the air receives heat from the medium, which is in the form of a high-temperature gas, and the temperature of the air increases.

Next, air flow will be explained in detail. The air blower 80 includes, for example, a fan and a motor. The motor rotates the fan. The fan generates a first airflow F1 and a second airflow F2. The first airflow F1 passes through the first chamber 91, the second chamber 92, and the fifth chamber 95 in this order. The second airflow F2 passes through the first chamber 91, the third chamber 93, the fourth chamber 94, and the fifth chamber 95 in this order.

Furthermore, the first airflow F1 and the second airflow F2 in the dehumidification mode will be explained in detail. As shown in FIG. 6, the user first empties the humidification tank 70. Next, the user drives the dehumidifying section 20 using the operation panel 11c. As a result, the first airflow F1 is dehumidified by the dehumidification section 20 when passing through the second chamber 92. Then, the dehumidification tank 50 accommodates the first water generated by the dehumidification section 20. Furthermore, the second airflow F2 is not humidified by the humidifier 60 when passing through the third chamber 93. Therefore, dehumidified air is released from the humidity control device 100.

Next, the first airflow F1 and the second airflow F2 in the humidification mode will be described in detail. As shown in FIG. 7, the user first stores a predetermined amount of second water in the humidifying tank 70. As shown in FIG. Note that the user does not drive the dehumidifying section 20. As a result, the first airflow F1 is not dehumidified by the dehumidification section 20 when passing through the second chamber 92. Further, the second airflow F2 is humidified by the humidification unit 60 when passing through the third chamber 93. Therefore, humidified air is released from the humidity control device 100.

Note that, as shown in FIGS. 3 to 5, the dehumidification tank 50 and the humidification tank 70 can be separated from each other when removed from the housing 10. That is, the dehumidification tank 50 and the humidification tank 70 can be attached to or detached from each other while being removed from the housing 10. Therefore, in this embodiment, even if the humidification tank 70 is not attached to the housing 10, dehumidification can be performed in the dehumidification mode. As shown in FIG. 8, a dehumidification tank 50 is arranged inside the third chamber 93. Note that the humidifying tank 70 and the humidifying section 60 are not arranged inside the third chamber 93.

Next, details of the configuration of the second water receiving section 40 will be described with reference to FIG. 1, FIG. 9A, and FIG. 9B. As shown in FIG. 9A, it is preferable that the second water receiving section 40 is detachable from the dehumidification tank 50. This is because the user can easily maintain the second water receiving section 40. When the humidification tank 70 is not installed in the dehumidification tank 50, the second water receiving part 40 is connected to the upper part of the third wall 55 of the dehumidification tank 50, the upper part of the second wall 54, and the fourth wall, for example. It is removable from the upper part of 56.

Furthermore, when the second water receiving part 40 is attached to the dehumidifying tank 50, the second water receiving part 40 is located between the outer surface of the humidifying tank 70 and the inner surface of the dehumidifying tank 50, and is located in the same position as the opening 50a. It is preferable to cover the area. The outer surface of the humidification tank 70 indicates the outer surface of the third wall 75. The inner surface of the dehumidification tank 50 indicates the inner surface of the third wall 55. When the humidification tank 70 is installed in the dehumidification tank 50, the second water receiving part 40 is connected to the upper part of the third wall 75 of the humidification tank 70 and the upper part of the third wall 55 of the dehumidification tank 50, for example. , are attached to the upper part of the second wall 54 and the upper part of the fourth wall 56. Therefore, the second water receiving section 40 can restrict movement of the humidifying tank 70 in the pushing direction D1 with respect to the dehumidifying tank 50.

Furthermore, as shown in FIGS. 9A and 9B, the second water receiving section 40 includes a second bottom section 42, a third bottom section 43, a first wall section 44, a second wall section 45, and a third wall section. 46 and a protrusion 47. The second water receiving part 40 is, for example, funnel-shaped. The second bottom portion 42 and the third bottom portion 43 are adjacent to each other and constitute the bottom portion of the second water receiving portion 40 . The second bottom portion 42 and the third bottom portion 43 receive the first water generated by the dehumidification unit 20 . The second bottom portion 42 and the third bottom portion 43 are located on the back side and the front side, respectively, in the front view direction D2. The third bottom portion 43 extends horizontally. The second bottom part 42 is inclined with respect to the third bottom part 43, and descends as it approaches the third bottom part 43. Therefore, the first water easily flows from the second bottom part 42 to the third bottom part 43. The first wall portion 44 , the second wall portion 45 , and the third wall portion 46 are erected from the third bottom portion 43 . The first wall portion 44 and the second wall portion 45 face each other. The upper end portions of the second bottom portion 42, the first wall portion 44, the second wall portion 45, and the third wall portion 46 project outward. For example, the protrusion 47 protrudes upward from the second wall 45. The protrusion 47 is, for example, a rib. It is preferable that the protrusion 47 has a surface along the front view direction D2. Furthermore, it is preferable that the protrusion 47 has an L-shape when viewed in cross section. This is because the strength of the protrusion 47 is improved and the protrusion 47 comes into contact with the second water receiving part 40 more easily.

Further, the hole 41 is preferably formed at the base end of the third wall 46. The first water guided from the first hole 31 of the first water receiving part 30 flows down to the second bottom part 42 or the third bottom part 43 of the second water receiving part 40 . Thereafter, the first water falls into the dehumidification tank 50 through the hole 41. Therefore, the first water guided from the first hole 31 of the first water receiving part 30 can be prevented from falling directly into the dehumidifying tank 50. As a result, the generation of water noise can be further reduced.

Furthermore, as described with reference to FIG. 5, when the humidifying tank 70 is placed in the dehumidifying tank 50, the humidifying tank 70 is slid in the direction D3 opposite to the pushing direction D1, as shown in FIG. 9A. Humidification tank 70 is fixed to dehumidification tank 50. That is, the humidification tank 70 is fixed at an appropriate position relative to the dehumidification tank 50. Specifically, each of the first protrusion 59a, the second protrusion 59b, the third protrusion 59c, and the fourth protrusion 59d of the dehumidification tank 50 restricts the upward movement of the humidification tank 70. Humidification tank 70 is fixed to dehumidification tank 50. As a result, rattling of the humidifying tank 70 with respect to the dehumidifying tank 50 can be further suppressed.

Next, details of the configuration of the first water receiving section 30 will be described with reference to FIGS. 1 to 12C. 10A and 10B are perspective views showing the first water receiving section 30. FIG. FIG. 10A shows the first water receiving section 30 viewed from below. FIG. 10B shows the first water receiving section 30 viewed from above. FIG. 11A is a bottom view showing the first water receiving section 30. FIG. FIG. 11B is a cross-sectional view taken along line XIB-XIB in FIG. 11A. 12A to 12C are perspective views showing a part of the first water receiving section 30. FIG.

As shown in FIGS. 10A and 10B, the first water receiving section 30 includes, in addition to the first hole 31, the plug section 32, and the positioning section 36, an upstream water receiving chamber 33 and a downstream water receiving chamber 34. It further includes. In addition, in FIG. 10A, FIG. 11A, and FIG. 11B, in order to make the form of the 1st hole part 31 easy to see, description of the plug part 32 is abbreviate|omitted.

The upstream water receiving chamber 33 is located below the dehumidifying section 20 , preferably directly below the dehumidifying section 20 . For example, the upstream water receiving chamber 33 is located below the evaporator 21. The upstream water receiving chamber 33 is open at the top and receives the first water generated by the dehumidifying section 20 . The first water received by the upstream water receiving chamber 33 flows within the upstream water receiving chamber 33 toward the downstream water receiving chamber 34 . That is, the upstream water receiving chamber 33 is located on the upstream side of the movement of the first water with respect to the downstream water receiving chamber 34. For example, the upstream water receiving chamber 33 is located on the front side of the downstream water receiving chamber 34 in the pushing direction D1.

The shape of the upstream water receiving chamber 33 corresponds to the shape of the lower end of the dehumidifying section 20. For example, the upstream water receiving chamber 33 corresponds to the shape of the lower end of the evaporator 21 . The upstream water receiving chamber 33 has, for example, a groove shape extending along the pushing direction D1.

The upstream water receiving chamber 33 has a bottom portion 33a and a plurality of walls. The plurality of walls are erected from the bottom 33a. The plurality of walls are, for example, a first wall 33b, a second wall 33c, a third wall 33d, and a fourth wall 33e, and constitute four side surfaces of the upstream water receiving chamber 33. The first wall portion 33b and the second wall portion 33c are opposed to each other and extend along the pushing direction D1 of the upstream water receiving chamber 33. The first wall portion 33b and the second wall portion 33c are located on the back side and the front side in the front view direction D2, respectively. The third wall portion 33d and the fourth wall portion 33e face each other and extend along the front view direction D2. The third wall portion 33d and the fourth wall portion 33e are located on the front side and the back side in the pushing direction D1, respectively. A through hole 33f is formed at the base end of the fourth wall portion 33e.

The bottom portion 33a includes a slope that descends in the pushing direction D1. Therefore, the first water easily flows toward the downstream water receiving chamber 34. As a result, retention of the first water in the upstream water receiving chamber 33 can be reduced.

The downstream water receiving chamber 34 is located on the downstream side of the movement of the first water with respect to the upstream water receiving chamber 33. For example, the downstream water receiving chamber 34 is adjacent to the fourth wall 33e of the upstream water receiving chamber 33, and is located on the back side of the upstream water receiving chamber 33 in the pushing direction D1. The downstream water receiving chamber 34 has, for example, a box shape with an open upper part.

The downstream water receiving chamber 34 has a bottom portion 34a and a plurality of walls. The bottom portion 34a corresponds to an example of a “first bottom portion”. The plurality of walls are erected from the bottom 34a. The position of the bottom part 34a is lower than the position of the bottom part 33a of the upstream water receiving chamber 33 in the vertical direction. The plurality of walls are, for example, a first wall 34b, a second wall 34c, a third wall 34d, and a fourth wall 34e, and constitute four side surfaces of the downstream water receiving chamber 34. The first wall portion 34b and the second wall portion 34c are opposed to each other and extend along the front view direction D2. The first wall portion 34b and the second wall portion 34c are located on the front side and the back side in the pushing direction D1, respectively. The first wall portion 34b is closer to the through hole 33f of the upstream water receiving chamber 33 than the second wall portion 34c. The height of the first wall portion 34b is lower than the position of the through hole 33f of the upstream water receiving chamber 33. The third wall portion 34d and the fourth wall portion 34e are opposed to each other and extend along the pushing direction D1. The third wall portion 34d and the fourth wall portion 34e are located on the front side and the back side in the front view direction D2, respectively.

The downstream water receiving chamber 34 receives the first water flowing from the upstream water receiving chamber 33 through the through hole 33f.

The first hole 31 is arranged at the base end of the fourth wall 34e. Specifically, the first hole 31 has, for example, a cylindrical shape extending in the horizontal direction. The first hole 31 extends, for example, along the front view direction D2. The first hole 31 has a cylinder 31a, an external opening 31b, and an internal opening 31c. The first hole 31 penetrates the fourth wall 34e of the downstream water receiving chamber 34. The first water received by the downstream water receiving chamber 34 flows through the cylinder 31a from the internal opening 31c toward the external opening 31b.

Furthermore, it is preferable that the first water receiving part 30 further includes a second hole part 35. Specifically, the first water receiving section 30 has two drainage positions 30a. Of the two drainage positions 30a, the first hole 31 is arranged at one drainage position 30a, and the second hole 35 is arranged at the other drainage position 30a. The second hole 35 has a cylindrical shape extending in the vertical direction. As shown in FIGS. 11A and 11B, the second hole 35 penetrates the bottom 34a. The second hole 35 has an upper opening 35a, a tube 35b, and a lower opening 35c. The position of the upper opening 35a is higher than the position of the first hole 31 in the vertical direction. The position of the first hole 31 indicates, for example, the position of the bottom 31a1 of the cylinder 31a of the first hole 31. The lower opening 35c faces the dehumidification tank 50. That is, the dehumidification tank 50 is located below the lower opening 35c.

According to this preferable example, since the lower opening 35c of the second hole 35 faces the dehumidifying tank 50, the user forgets to attach the second water receiving part 40 to the dehumidifying tank 50 and the casing 10 is dehumidified. Even if the tank 50 is pushed in and the dehumidifying operation is started, it is possible to suppress the first water from falling outside the dehumidifying tank 50. Therefore, leakage of the first water within the housing 10 can be suppressed, and the user's sense of security against forgetting to attach the second water receiving part 40 can be improved.

Moreover, as shown in FIG. 12A, the positioning part 36 is preferably configured as a part of the outer wall portion of the outer wall 30b of the first water receiving part 30 that faces the humidification tank 70. The positioning portion 36 has a planar shape. According to this preferable example, the positioning part 36 contacts the humidification tank 70 as a surface, and thus easily contacts the humidification tank 70. Therefore, the positioning section 36 can easily push the humidifying tank 70 back in the direction D3 opposite to the pushing direction D1.

Furthermore, it is preferable that the outer wall portion where the positioning portion 36 is configured is included in the outer wall 34w of the downstream water receiving chamber 34. The outer wall 34w includes, for example, the bottom 34a of the downstream water receiving chamber 34, the first wall 34b, the second wall 34c, the third wall 34d, and the fourth wall 34e. When the humidifying tank 70 is disposed inside the dehumidifying tank 50 (see FIG. 1) and in the first accommodation state (see FIG. 2), the outer wall portion facing the humidifying tank 70 is the first wall portion 34b. According to this preferred example, the outer wall 34w of the downstream water receiving chamber 34 can also serve as the positioning part 36. Therefore, the humidification tank 70 can be positioned without increasing the number of parts.

Furthermore, as shown in FIG. 12B, it is preferable that the positioning part 36 protrudes from the outer wall portion facing the humidification tank 70 in the direction D3 opposite to the pushing direction D1. The positioning portion 36 has, for example, a frustum shape. According to this preferred example, the humidification tank 70 can be pushed back a longer distance. Therefore, the humidifying tank 70 can be effectively pushed back in the opposite direction D3.

Further, as shown in FIG. 12C, the positioning part 36 preferably protrudes from the outer wall portion facing the humidification tank 70 in the direction D3 opposite to the pushing direction D1, and extends in a stripe shape along the vertical direction. . According to this preferred example, even if the position of the humidification tank 70 changes in the vertical direction, the positioning portion 36 can easily come into contact with the humidification tank 70. Therefore, the positioning section 36 can effectively and easily push the humidification tank 70 back in the opposite direction D3.

Next, the details of the configuration of the stopper portion 32 will be described with reference to FIGS. 1 and 9A to 11B, and further to FIGS. 13A to 15. 13A and 13B are perspective views showing the plug portion 32. FIG. Specifically, FIGS. 13A and 13B show the plug portion 32 as viewed from the front side and the back side, respectively. FIG. 14 is a perspective view showing the first water receiving section 30. FIG. 15 is a diagram showing the inside of the humidity control device 100.

As shown in FIG. 13A, the plug portion 32 has an abutting piece 32a and a plug body 32b. The contact piece 32a projects toward the bottom plate 12 of the housing 10 from the plug body 32b. For example, the contact piece 32a projects vertically downward. The contact piece 32a is, for example, a rib. The contact piece 32a is, for example, plate-shaped. The contact piece 32a contacts the protrusion 47 of the second water receiving portion 40. Specifically, of both ends of the contact piece 32a along the pushing direction D1, the end 32a1 on the near side in the pushing direction D1 comes into contact with the protrusion 47. It is preferable that the contact piece 32a has an L-shape when viewed in cross section. That is, it is preferable that the end portion 32a1 has a surface parallel to the front view direction D2. This is because the strength of the abutting piece 32a is improved and the abutting piece 32a comes into contact with the protrusion 47 of the second water receiving part 40 more easily.

As shown in FIGS. 13A and 13B, the plug body 32b includes an arm portion 32c, a shaft portion 32d, and a plug member 32e. The arm portion 32c includes a first arm portion 32c1 and a second arm portion 32c2. The first arm portion 32c1 extends along the front view direction D2. The second arm portion 32c2 extends along the pushing direction D1. The second arm portion 32c2 is connected to the contact piece 32a. For example, the arm portion 32c rotates in the horizontal direction. The horizontal direction includes a first rotation direction R1 and a second rotation direction R2. Specifically, the arm portion 32c rotates about the shaft portion 32d in the first rotation direction R1 or the second rotation direction R2. The first rotation direction R1 and the second rotation direction R2 respectively indicate a counterclockwise direction and a clockwise direction in plan view. The second rotation direction R2 corresponds to an example of a "rotation direction."

The shaft portion 32d is located at one end of the arm portion 32c, that is, on the first arm portion 32c1 side. The shaft portion 32d has, for example, a hole penetrating therethrough along the axis AX. For example, the axis AX extends along the vertical direction. The shaft portion 32d has a biasing member 32d1. The biasing member 32d1 is, for example, a torsion coil spring. The biasing member 32d1 biases the arm portion 32c in the second rotation direction R2.

The plug member 32e is located at the other end of the arm portion 32c, that is, on the second arm portion 32c2 side. The plug member 32e is, for example, disc-shaped. The plug member 32e is, for example, a rubber packing. The plug member 32e faces the external opening 31b of the first hole 31 and is capable of sealing the external opening 31b.

As shown in FIGS. 10A and 14, the plug body 32b closes the first hole 31. As shown in FIGS. The plug body 32b is attached to the outer surface of the downstream water receiving chamber 34, for example. Specifically, the hole of the shaft portion 32d fits into a vertically extending cylindrical body provided on the outer surface of the downstream water receiving chamber 34.

As shown in FIGS. 14 and 15, the biasing member 32d1 biases the arm portion 32c in a state where the protrusion 47 of the second water receiving portion 40 is not pushing the contact piece 32a. The plug member 32e closes the external opening 31b in response to the biasing force applied to the arm portion 32c by the biasing member 32d1. According to this embodiment, since the biasing member 32d1 biases the arm portion 32c in the second rotation direction R2, the external opening 31b of the first hole 31 can be more strongly closed. Therefore, unintentional leakage of the first water from the first hole 31 can be reduced.

Furthermore, according to the present embodiment, when the dehumidification tank 50 is not located in the interior 10a of the housing 10, the plug part 32 is separated from the second water receiving part 40 and closes the first hole part 31. Since the position of the upper opening 35a of the second hole 35 of the first water receiving part 30 is higher than the position of the first hole 31 in the vertical direction, the user does not store the dehumidification tank 50 in the housing 10. Even if the first water is generated in the dehumidifying section 20 during this period, the first water does not flow into the upper opening 35a unless a certain amount or more of the first water accumulates at the bottom 34a of the downstream water receiving chamber 34. Therefore, after the user takes out the dehumidification tank 50 from the housing 10, it is possible to delay the first water from falling from the first water receiving part 30 to the bottom of the housing 10.

Continuing with reference to FIGS. 13A and 13B, and further reference to FIGS. 16A to 17B, details of the opening/closing operation of the plug section 32 with respect to the first hole 31 and the pushing operation of the positioning section 36 with respect to the humidifying tank 70 will be explained. The details will be explained below. 16A and 17B are diagrams showing a part of the inside of the humidity control device 100. FIG. 16B is a partially enlarged view showing the first water receiving section 30 and the second water receiving section 40. FIG. FIG. 17B is an enlarged view of portion XVIIB in FIG. 17A.

As shown in FIG. 16A, when the dehumidifying tank 50 is located inside the housing 10 with the second water receiving part 40 attached to the dehumidifying tank 50, the abutting piece 32a of the plug part 32 is The first hole 31 is opened by contacting the protrusion 47 of the second water receiving portion 40 .

Specifically, as shown in FIG. 16B, in a state where the dehumidification tank 50 is located inside the housing 10, the protrusion 47 pushes the contact piece 32a into the interior 10a of the housing 10 in the pushing direction D1. As the contact piece 32a is pushed, the arm portion 32c rotates in the first rotation direction R1. The plug body 32b opens the external opening 31b of the first hole 31 in a state where the projection 47 is pushing the contact piece 32a. Therefore, the first water generated by the dehumidification operation can be collected into the dehumidification tank 50 with a simple configuration in conjunction with the operation of storing the dehumidification tank 50 in the housing 10, and the generation of water noise can be reduced.

Furthermore, as shown in FIGS. 9A and 16A, according to the present embodiment, the second water receiving part 40 is located between the outer surface of the humidifying tank 70 and the inner surface of the dehumidifying tank 50, and is located in a part of the opening 50a. Therefore, it is possible to restrict movement of the humidifying tank 70 in the pushing direction D1 with respect to the dehumidifying tank 50. Therefore, when the dehumidifying tank 50 is pushed into the housing 10, the dehumidifying tank 50 can be positioned at a position where the first water does not fall into the humidifying tank 70. As a result, mixing of the first water into the second water in the humidifying tank 70 can be suppressed with a small number of parts.

Furthermore, according to the present embodiment, the positioning part 36 comes into contact with the humidification tank 70 in the first accommodated state, so that the positioning part 36 pushes back the humidification tank 70 in the direction D3 opposite to the pushing direction D1. Therefore, the humidification tank 70 can be placed at an appropriate position relative to the dehumidification tank 50 more reliably. The appropriate position is, for example, a position where the humidification tank 70 is fixed to the dehumidification tank 50 (see FIG. 9A), and a detection unit (not shown) that detects the amount of second water in the humidification tank 70 (for example, a magnetic sensor). ) is the position where a detected object (for example, a float) in the humidifying tank 70 is detected. As a result, even if the user forgets to slide the humidifying tank 70 in the opposite direction D3 when attaching the humidifying tank 70 to the dehumidifying tank 50, the humidifying tank can be moved to the appropriate position without bothering the user. 70 can be placed.

Furthermore, further details of the push-back operation of the humidifying tank 70 by the positioning section 36 will be described with reference to FIGS. 11A and 11B and FIGS. 17A and 17B. FIG. 17A shows a state in which the second water receiving section 40 is not attached to the dehumidification tank 50 and in a first accommodated state. As shown in FIG. 17A, for example, the positioning section 36 is configured to be in contact with the humidifying tank 70 when the second water receiving section 40 is not attached to the dehumidifying tank 50 and the dehumidifying tank 50 is located inside the housing 10. come into contact with

Specifically, as shown in FIGS. 17A and 17B, the positioning portion 36 contacts the upper end portion 78c1 of the second leg portion 78c of the grip portion 78 of the humidification tank 70. When the positioning part 36 comes into contact with the upper end part 78c1, the second hole part 35 arranged at the drainage position 30a (see FIGS. 11A and 11B) does not overlap with the humidification tank 70 in plan view, but overlaps with the dehumidification tank 50. . That is, the positioning part 36 contacts the humidification tank 70 and pushes the humidification tank 70 back in the direction D3 opposite to the pushing direction D1 to a position where the second hole part 35 and the humidification tank 70 are shifted from each other. Therefore, even if the dehumidifying tank 50 is pushed into the housing 10 while the user forgets to attach the second water receiving part 40, the first water will not fall from the second hole part 35 into the humidifying tank 70. In other words, the humidifying tank 70 can be positioned at an appropriate position. As a result, it is possible to improve the user's sense of security against forgetting to attach the second water receiving part 40, and to suppress the mixing of the first water into the second water in the humidifying tank 70 with a small number of parts.

Furthermore, as shown in FIGS. 9A and 17A, according to the present embodiment, it is preferable that the second water receiving section 40 is detachable from the dehumidifying tank 50. When the second water receiving part 40 is not attached to the dehumidifying tank 50, the plug part 32 is separated from the second water receiving part 40 and closes the first hole part 31. Therefore, during maintenance work such as removing and cleaning the second water receiving section 40, unintended water leakage can be suppressed.

The embodiments of the present invention have been described above with reference to the drawings. However, the present invention is not limited to the above-described embodiments, and can be implemented in various forms without departing from the spirit thereof. Moreover, various inventions can be formed by appropriately combining a plurality of constituent elements of a plurality of embodiments. For example, some components may be deleted from all the components shown in the embodiments. Furthermore, components of different embodiments may be combined as appropriate. For ease of understanding, the drawing mainly shows each component schematically, and the thickness, length, number, spacing, etc. of each component shown in the diagram may differ from the actual one for convenience of drawing. is different. Further, the materials, shapes, etc. of each component shown in the above embodiments are merely examples, and are not particularly limited, and various changes can be made without substantially departing from the configuration of the present invention.

(1) As described with reference to FIGS. 10A and 10B, there is one upstream water receiving chamber 33, but the present invention is not limited to this. The upstream water receiving chamber 33 only needs to be able to receive water generated in the dehumidification tank 50. For example, there may be a plurality of upstream water receiving chambers 33. Further, the downstream water receiving chamber 34 may directly receive water generated in the dehumidification tank 50 similarly to the upstream water receiving chamber 33.
