(Integral Structure of humidity controlling apparatus)

According to the present utility model, the humidity conditioning apparatus 100 includes a housing 10. The humidity control apparatus 100 of the present embodiment is used as a dehumidifier, for example. The housing 10 includes: an outer wall portion 11 provided with an air inlet JF and an air outlet CF; and a heat insulation inner chamber 12 and a drain pan 30 provided in the outer wall 11, wherein a humidity control module 20 is provided in the heat insulation inner chamber 12. The heat insulating cavity 12 is a box having a cavity opening 12a at the bottom, and at least a portion of the drain pan 30 is fitted into the cavity opening 12a. For example, a ventilation device (not shown) may be provided upstream of the humidity control apparatus 100 to guide the outdoor air to the humidity control apparatus 100.

The outer wall portion 11 may be made of, for example, a resin, a metal material, or a polymer, and encloses an accommodation space formed inside. The outer wall 11 is, for example, a rectangular parallelepiped. The humidity control apparatus 100 may be mounted at a desired mounting position by the outer wall portion 11, for example, hung on a wall body vertical to the room or hung on a ceiling of the room.

In the above-described accommodation space, the humidity control apparatus 100 includes the heat insulation inner chamber 12. In the present embodiment, the heat insulating inner chamber 12 is attached to the inside of the outer wall 11. The outer side surface of the heat insulating inner chamber 12 is in partial contact with or in complete contact with the inner side surface of the outer wall portion 11, for example.

As exemplarily shown in fig. 2-6, the insulated interior cavity 12 is generally rectangular parallelepiped-shaped. A gas flow path of the humidity control apparatus 100 is formed inside the heat insulating inner chamber 12. Specifically, the heat insulating inner chamber 12 is provided with a first opening 121 corresponding to the air inlet JF and a second opening 122 corresponding to the air outlet CF. The first opening 121 and the air inlet JF are used to introduce air into the humidity conditioning apparatus 100, and the second opening 122 and the air outlet CF are used to discharge the treated air out of the humidity conditioning apparatus 100.

The humidity control apparatus 100 includes an electrical component box 40, and the electrical component box 40 is fixed to an outer wall side wall 112 of the outer wall 11, for example, and is internally provided with a circuit board or the like for controlling the operation of the humidity control apparatus 100.

(Structure of outer wall portion)

As described above, the outer wall portion 11 is provided with the air inlet JF and the air outlet CF. The outer wall 11 is substantially enclosed in a rectangular parallelepiped shape by an outer wall bottom wall (not shown), an outer wall top wall 111, and an outer wall side wall 112. The outer wall top wall 111 is opposed to the outer wall bottom wall with a space therebetween in the up-down direction. The outer wall side wall 112 connects the periphery of the outer wall bottom wall with the periphery of the outer wall top wall 111, and includes: first and second outer wall side walls 1121 and 1122 opposed to each other with a space therebetween in the Y direction; and third and fourth outer wall side walls 1123 and 1124 opposed to each other at a spacing in the X direction, the third and fourth outer wall side walls 1123 and 1124 connecting the first and second outer wall side walls 1121 and 1122, respectively. The first outer wall 1121 has an air inlet JF, and the second outer wall 1122 has an air outlet CF. The first outer wall side wall 1121, the second outer wall side wall 1122, the third outer wall side wall 1123, and the fourth outer wall side wall 1124 are each, for example, rectangular plate-shaped.

Further, for example, a lower edge of each of the first, second, third, and fourth outer wall side walls 1121, 1122, 1123, 1124 is provided with a bent portion bent inward for holding the heat insulating inner chamber 12.

(Structure of Heat-insulating inner Chamber)

A heat insulating inner chamber 12 is provided inside the outer wall 11. In the present utility model, the heat insulating inner chamber 12 is a separate housing independent of the outer wall portion 11. The outer side surface of the heat insulating inner chamber 12 is at least partially in contact with the inner side surface of the outer wall portion 11. The outer surface of the heat insulating inner chamber 12 may be matched in shape and size to the inner surface of the outer wall 11, for example, the heat insulating inner chamber 12 is in close contact with the outer wall 11. Further, a part of the outer surface of the heat insulating inner chamber 12 may be opposed to the inner surface of the outer wall 11 with a slight gap.

In this embodiment, the heat insulating inner chamber 12 is integrally formed as a box having an inner chamber opening 12a at the bottom. The lumen opening 12a faces downward. Compared with a case assembled by different components, the case formed integrally can significantly reduce gaps caused by assembly (e.g., splicing), thereby improving the sealing performance of the humidity control apparatus 100 and reducing air leakage. The heat insulation inner chamber 12 has a rectangular parallelepiped shape. As shown in fig. 3 and 5, the insulated cavity 12 includes a top wall 123 and a side wall portion 124 extending downwardly from the periphery of the top wall 123. The top wall 123 closes the upper opening of the side wall portion 124, and can improve the sealing performance. The top wall 123 may be provided with a top wall abutting portion that abuts the top of a heat exchanger described below of the dehumidification unit, and suppresses displacement of the heat exchanger. The top wall 123 and the side wall portion 124 enclose an interior space. In the present embodiment, the main body portions of the humidity control module 20 and the drain pan 30 are provided in the internal space.

The heat insulation inner chamber 12 is a foam integrated structure or a resin molded structure. Suitable foaming materials include polystyrene (EPS), and suitable resin materials include, for example, flexible resin materials such as ABS, PP, HIPS, POM, and non-flexible resin materials may also be used. Preferably, the insulating cavity 12 is a foam-in-one structure, or a soft resin molded structure, whereby upon application of pressure (e.g., an insert member), the materials may deform somewhat, which also helps create a tight fit with the member that it receives or engages, thereby improving sealing performance.

The side wall portion 124 includes: first and second sidewalls 1242 and 1241 spaced apart by an interval in the Y direction; and third and fourth side walls 1243 and 1244 opposite to each other with a space therebetween in the X direction, the third and fourth side walls 1243 and 1244 connecting the first and second side walls 1242 and 1241, respectively. Wherein, the first side wall 1242 is provided with the second opening 122, and the second side wall 1241 is provided with the first opening 121. In the X direction, the second opening 122 is disposed at a substantially middle position of the first side wall 1242. In the X direction, the first opening 121 is disposed at a substantially middle position of the second sidewall 1241.

The shape and size of the first and second openings 121 and 122 may be designed according to the amount of air flow required by the humidity control apparatus 100. In the present embodiment, the first opening 121 and the second opening 122 penetrate the second side wall 1241 and the first side wall 1242, respectively, along the Y direction. The first opening 121 is provided with an inclined surface portion 1211 at a lower portion when viewed in the X direction. The inclined surface 1211 is inclined so as to be located upward as it goes toward the inside of the heat insulating inner chamber 12, so as to guide the intake air. In the present embodiment, the first opening 121 and the second opening 122 are each formed in a substantially circular shape when viewed in the flow direction (Y direction) of the airflow. The first opening 121 overlaps the air inlet JF and the second opening 122 overlaps the air outlet CF when viewed in the flow direction of the air flow. In addition, the insulated cavity 12 may be provided with openings other than the cavity opening 12a at other locations, for example for mounting various components. But only the cavity opening 12a at the bottom is intended to mate with the drain pan 30.

Further, the first side wall 1242 has at least one first positioning portion S1 for positioning the drain pan 30. In the present embodiment, two first positioning portions S1 are provided. The first positioning portion S1 is located laterally of the second opening 122. The first positioning portion S1 is integrally formed with the first side wall 1242. The first positioning portion S1 is configured to protrude toward the humidity control module 20 in the thickness direction of the side wall of the heat insulation inner chamber 12 (the thickness direction of the first side wall 1242). As shown in fig. 5, the first positioning portion S1 protrudes from the inner side surface of the first side wall 1242 toward the side where the humidity control module 20 is located, i.e., the Y1 direction side.

In the present embodiment, the first positioning portions S1 are each rectangular when viewed in a direction (Y direction) orthogonal to the first side wall 1242. However, the present invention is not limited thereto, and the first positioning portion S1 may have a convex shape, a polygonal shape other than a rectangular shape, or the like when viewed in the Y direction. The first positioning portion S1 preferably has a shape matching the drain pan 30 when viewed in the Y direction, thereby further improving the sealing performance.

Preferably, when the direction in which the first positioning portion S1 and the second opening 122 are aligned (in the present embodiment, the X direction) is the first direction, the width of the first positioning portion S1 in the first direction is 100mm to 150mm. This makes it possible to easily ensure the strength of sealing and mounting the abutting drain pan 30. When the direction (in the present embodiment, the Z direction) orthogonal to the first direction and the thickness direction of the first side wall 1242 is the second direction, the first positioning portion S1 extends upward in the second direction from a position lower than the central axis of the second opening 122. From the viewpoint of reliably securing the fitting strength of the drain pan, it is preferable that the first positioning portion S1 extends upward to a position higher than the central axis of the second opening 122. From the viewpoint of ease of manufacturing the heat insulating inner chamber 12 (for example, ease of demolding), it is more preferable that the first positioning portion S1 extends upward to the tip end of the first side wall 1242 (connected to the top wall 123). In one example, the first positioning portion S1 has a dimension of 129mm in the above second direction.

Preferably, the thickness of the first positioning portion S1, i.e., the protruding amount protruding from the first side wall 1242 toward the humidity adjustment assembly 20 is equal to or more than 3mm and less than 10mm. Accordingly, after the first positioning portion S1 and the drain pan 30 are abutted, sealing can be reliably achieved, the drain pan 30 is ensured to be mounted in place, and air leakage is suppressed.

As shown in fig. 5, in the present embodiment, two first positioning portions S1a and S1b are provided. The two first positioning portions S1a, S1b are located on the X1 direction side (corresponding to "one side" of the present disclosure) and the X2 direction side (corresponding to "the other side" of the present disclosure) of the second opening 122, respectively.

The width dimensions of the two first positioning portions S1a, S1b are different from each other. As shown in fig. 6, when the minimum distance between one of the two first positioning portions S1a and the second opening 122 is L1 and the minimum distance between the other first positioning portion S1b and the second opening 122 is L2, L1 > L2. Here, "the minimum distance between the first positioning portion and the second opening" means the shortest distance between the first positioning portion and the second opening in the direction in which the first positioning portion and the second opening are aligned (in the present embodiment, the X direction). Preferably, the width of one of the first positioning portions S1a in the first direction is 100mm to 130mm, and the width of the other first positioning portion S1b in the first direction is 100mm to 150mm. In one example, one first positioning portion S1a has a dimension of 125mm in the first direction, and the other first positioning portion S1b has a dimension of 135mm in the first direction.

The side wall of the first positioning portion S1 on the side close to the second opening 122 preferably has an air guiding surface G that is chamfered. Thereby, air guiding can be facilitated.

In addition, the humidity conditioning device 100 may further include a sensor. In the present embodiment, a sensor (not shown) is mounted on the first side wall 1242 where the second opening 122 is located, for monitoring the air treatment condition of the humidity control apparatus 100, such as the dehumidification condition, the temperature control condition, or other physical parameters. For example, a temperature sensor or a humidity sensor or a temperature and humidity sensor may be used as the sensor. The sensor is disposed at a position between the first positioning portion S1 and the second opening 122. Preferably, the sensor is disposed at a position between a first positioning portion S1a and the second opening 122. Thus, the detection accuracy of the sensor can be reliably ensured. The sensor is fixed, for example, to the inner side of the first side wall 1242. Further, a sensor may not be provided.

Further, at least one second positioning portion S2 for positioning the drain pan 30 is provided on a side wall adjacent to the first side wall 1242, that is, the fourth side wall 1244 of the heat insulation inner chamber 12. In the present embodiment, one second positioning portion S2 is provided. The second positioning portion S2 is integrally formed with the fourth side wall 1244. The second positioning portion S2 is configured to protrude toward the humidity control module 20 in the thickness direction of the side wall of the heat insulation inner chamber 12 (the thickness direction of the side wall adjacent to the first side wall 1242). As shown in fig. 5, the second positioning portion S2 protrudes from the inner side surface of the fourth side wall 1244 toward the side where the humidity control module 20 is located, i.e., the X1 direction side.

In the present embodiment, the second positioning portion S2 has a rectangular shape when viewed in a direction (X direction) orthogonal to the fourth side wall 1244. The second positioning portion S2 extends, for example, over the Y-direction range of the fourth side wall 1244. However, the width of the second positioning portion S2 in the Y direction may be smaller than the width of the fourth side wall 1244 in the Y direction. Further, the second positioning portion S2 extends upward in the Z direction from the same height position as the first positioning portion S1, preferably to the tip end of the fourth side wall 1244. The thickness of the second positioning portion S2, i.e., the protruding amount protruding from the fourth side wall 1244 toward the humidity control assembly 20 is 3mm or more and < 10mm or less.

In addition, the insulated interior cavity 12 may be provided with access openings for convenient operation or viewing by maintenance personnel. The access opening is provided, for example, on one side wall of the insulated cavity 12.

(Humidity controlling component)

A humidity conditioning assembly 20 is disposed within the insulated interior cavity 12. In the present embodiment, the air flow flows from the air inlet JF to the air outlet CF in the Y direction, and the humidity adjusting unit 20 adjusts the humidity of the air flow flowing from the air inlet JF to the air outlet CF. The humidity control module 20 may have a known structure such as a heat exchanger or a rotary dehumidifier.

In the present embodiment, the humidity control module 20 includes a first heat exchanger 21 that exchanges heat with a refrigerant. A drain pan 30 is provided below the first heat exchanger 21 to receive condensed water dropped from the first heat exchanger 21 and a second heat exchanger 22 described later. The first heat exchanger 21 operates as an evaporator, for example, in the dehumidification operation.

Further, a second heat exchanger 22 that exchanges heat with the refrigerant is provided in the casing 110, and the second heat exchanger 22 is located downstream of the first heat exchanger 21 and operates as a condenser, for example, in the dehumidification operation. The first heat exchanger 21 and the second heat exchanger 22 are housed in a space surrounded by the heat insulating inner chamber 12 and the drain pan 30. The first heat exchanger 21 and the second heat exchanger 22 are fixed to the outer wall portion 11 of the casing 10, for example, by support members provided on respective side portions. The insulated cavity 12 may be provided with a gap through which the support member passes.

The first heat exchanger 21 is, for example, a fin-and-tube heat exchanger, and includes a plurality of fins arranged in the longitudinal direction of the heat exchanger and refrigerant tubes interposed between the fins. The second heat exchanger 22 is also, for example, a fin-and-tube heat exchanger. The first heat exchanger 21 and the second heat exchanger 22 are connected to an air conditioning outdoor unit (not shown), for example, via refrigerant pipes.

(Drainage tray)

The humidity control apparatus 100 further includes a drain pan 30 disposed below the humidity control assembly 20. In the present embodiment, the main body portion of the drain pan 30 is disposed below the humidity control module 20 inside the heat insulation chamber 12. The drain pan 30 covers the cavity opening 12a at the bottom of the insulated cavity 12.

The main body portion of the drain pan 30 has: a bottom wall 31; and a peripheral wall portion 32, the peripheral wall portion 32 standing upward from the peripheral edge of the bottom wall 31. The bottom wall 31 has a thickness in the up-down direction. The bottom wall 31 has a substantially rectangular shape in plan view. The peripheral wall portion 32 has: a first peripheral wall 321 and a second peripheral wall 322 opposed in the Y direction; and third and fourth peripheral walls 323 and 324 opposite in the X direction and connecting the first and second peripheral walls 321 and 322, respectively. The first peripheral wall 321 is a peripheral wall on the side of the first opening 121 (Y1 direction side), and the second peripheral wall 322 is a peripheral wall on the side of the second opening 122 (Y2 direction side). The storage space surrounded by the bottom wall 31 and the peripheral wall 32 receives condensed water.

The drain pan 30 is located below the first positioning portion S1 and the second positioning portion S2 in the vertical direction. Specifically, the upper end surface of the peripheral wall portion 32 of the drain pan 30 is located below the first positioning portion S1 and the second positioning portion S2.

The first positioning portion S1 and the second positioning portion S2 position the drain pan 30 in a direction perpendicular to the thickness direction of the side wall of the heat insulating inner chamber 12. In the present embodiment, the first positioning portion S1 and the second positioning portion S2 are in contact with the peripheral wall portion 32 of the drain pan 30 in the vertical direction. The first positioning portion S1 contacts the second peripheral wall 322 in the up-down direction, and positions the second peripheral wall 322 in the up-down direction. The lower end surface of the first positioning portion S1 abuts against the upper end surface of the second peripheral wall 322. The second positioning portion S2 contacts the fourth peripheral wall 324 in the up-down direction, and positions the fourth peripheral wall 324 in the up-down direction. The lower end surface of the second positioning portion S2 abuts against the upper end surface of the fourth peripheral wall 324. In this way, the first positioning portion S1, the second positioning portion S2, and the drain pan 30 come into contact with each other, thereby realizing sealing. The first positioning portion S1 and the second positioning portion S2 also serve as abutment limiting positions for the end portions of the drain pan 30 at the time of assembly, and can be secured in place to suppress air leakage.

In addition, the drain pan 30 includes a drain opening 33. The drain opening 33 is provided in the third peripheral wall 323. The drain opening 33 protrudes outward from the outer surface of the third peripheral wall 323, for example. The water in the drain pan 30 is discharged to the outside of the humidity control apparatus through the drain port 33.

The outer dimension of the main body portion of the drain pan 30 in plan view is preferably matched with the dimension of the cavity opening 12a at the bottom of the heat insulating cavity 12 to further improve the sealing property. In the present embodiment, the outer dimension of the main body portion of the drain pan 30 in plan view is, for example, approximately equal to the dimension of the cavity opening 12a at the bottom of the heat insulation cavity 12. However, the outer dimension of the main body portion of the drain pan 30 in plan view may be smaller than the dimension of the cavity opening 12a at the bottom of the heat insulating cavity 12.

Further, a proper recess, protrusion, bent portion, etc. may be provided on the bottom wall 31 of the drain pan 30 to guide the condensed water to the drain port 33. The material of the drain pan 30 is not particularly limited, and may be, for example, a foam-integrated structure or a resin-molded structure.

The bottom wall 31 of the drain pan 30 may be provided with a bottom wall contact portion that contacts, for example, the bottom of the heat exchanger of the dehumidification unit, thereby suppressing displacement of the heat exchanger.

The utility model has been described above by way of example with reference to the accompanying drawings, it being apparent that the utility model is not limited to the embodiments described above.

For example, in the above embodiment, the first positioning portion S1 is provided on the first side wall 1242 where the second opening 122 is located.
