According to one embodiment of the utility model, a fan 13 for auxiliary intake air may be provided in the housing near the intake or outside the housing. When the fan 13 is arranged in the shell, the fan 13 is arranged at a position, outside the evaporator 12 and the condenser, close to the air inlet, and the air inlet surface 102 of the fan 13 faces the air inlet, so that a negative pressure area is formed at the air inlet, and air is easier to enter from the air inlet.

According to an embodiment of the present utility model, the fan 13 provided in the housing specifically uses an axial flow fan 13. When the axial flow fan 13 is operated, the blades push the air to flow in the same direction as the shaft, so that the wind direction of the axial flow fan 13 is generally linear, that is, the air located at one side of the axial flow fan 13 can directly pass through the axial flow fan 13 to reach the other side in a straight path. The axial flow fan 13 is used in the present embodiment, and the air treated by the evaporator 12 and the condenser 11 can be rapidly discharged into the space.

According to an embodiment of the present utility model, in order to accommodate the installation of the axial flow fan 13, the air outlet 15 formed on the air outlet face 101 of the housing needs to be adapted in shape and area to the axial flow fan 13.

According to one embodiment of the present utility model, since the housing is relatively closed, when the axial flow fan 13 is operated, the housing may be sucked through the air inlet because the air flow direction is single to the outside of the housing, thereby causing a negative pressure state in the housing.

According to one embodiment of the present utility model, considering that the evaporator 12 and the condenser 11 are provided in the housing in this embodiment, and the products of the evaporator 12 and the condenser 11 are liquid water, which is required to be discharged through several kinds of drain pipes 4 after collection, in order to collect the liquid water more conveniently, a tray for receiving the liquid water is provided at the bottom of the housing, and the drain pipes 4 are connected to the tray. More specifically, the front projection of the evaporator 12 and the condenser 11 on the tray is smaller than the area of the tray, so that the tray can receive liquid water from the evaporator 12 and the condenser 11. The specific shape of the tray may be rectangular.

According to one embodiment of the utility model, the tray may serve as a housing floor. Specifically, when the tray is used as the bottom plate of the housing, four peripheral edges of the tray are respectively connected with the left side plate and the right side plate of the air outlet face 101 and the air inlet face 102. The tray is a whole plate, and annular bulges are connected to the periphery of the tray to prevent liquid water from flowing out. In yet another embodiment, the tray is gradually recessed from the periphery to the middle portion, so that the liquid water can flow to the middle portion of the tray after being influenced by gravity, and then is converged at the middle portion of the tray, and the drain pipe 4 is communicated with the lowest position of the middle portion of the tray, so that the water converged at the middle portion of the tray can flow out through the drain pipe 4.

The tray is a whole plate, and annular bulges are connected to the periphery of the tray to prevent liquid water from flowing out. In yet another embodiment, the tray is gradually recessed from the periphery to the middle portion, so that the liquid water can flow to the middle portion of the tray after being influenced by gravity, and then is converged at the middle portion of the tray, and the drain pipe 4 is communicated with the lowest position of the middle portion of the tray, so that the water converged at the middle portion of the tray can flow out through the drain pipe 4.

According to one embodiment of the utility model, the tray may serve as a housing floor. Specifically, when the tray is used as the bottom plate of the housing, four peripheral edges of the tray are respectively connected with the left side plate and the right side plate of the air outlet face 101 and the air inlet face 102. The tray is a whole plate, and annular bulges are connected to the periphery of the tray to prevent liquid water from flowing out. In yet another embodiment, the tray is gradually recessed from the periphery to the middle portion, so that the liquid water can flow to the middle portion of the tray after being influenced by gravity, and then is converged at the middle portion of the tray, and the drain pipe 4 is communicated with the lowest position of the middle portion of the tray, so that the water converged at the middle portion of the tray can flow out through the drain pipe 4.

According to one embodiment of the utility model, the drain pipe 4 is a flexible pipe. The drain pipe 4 in this embodiment is used to drain the water in the tray to the outside. In order to pass through the wall of the water supply and drainage pipe 4, the wall is required to be provided with a through hole so that the water drainage pipe 4 passes through the wall through the water drainage hole, and then the tail end of the water drainage pipe 4 is empty outdoors, and when the liquid in the water drainage pipe 4 needs to be discharged, the liquid is directly discharged to the outdoor environment from the tail end of the water drainage pipe 4. Taking a dehumidifier rated for 13L/day as an example, it can discharge 13L of water per day according to the rated dehumidification amount, however, in a daily environment, it is far from the rated value, and the water is discharged relatively continuously in one day, and the influence on the external environment is low.

According to one embodiment of the present utility model, a hard pipe section for accommodating and supporting the drain pipe 4 is further provided in the wall 5, the hard pipe section is embedded in the through hole of the wall 5, the inner diameter of the hard pipe section is larger than the outer diameter of the drain pipe 4, and the length of the hard pipe section is larger than the thickness of the wall 5. In some examples, assuming that the thickness of the wall 5 is L, in order to avoid bending damage of the drain pipe 4, a certain length allowance needs to be provided for the drain pipe 4 so that the drain pipe 4 can be bent slowly, and the distance from the starting bending position of the drain pipe 4 in the wall to the surface of the outer wall 5 is greater than the thickness of the wall 5, and accordingly, the length of the hard pipe section corresponding to the section is also greater than the thickness of the wall 5 so as to form better protection for the drain pipe 4.

According to one embodiment of the utility model, the shape of the hard pipe section may vary with the drain pipe 4. In some examples, in order to avoid bending damage to the drain pipe 4, the portion of the drain pipe 4 near the through hole in the wall 5 needs to be slowly bent to form a round angle, and the radius of the round angle meets the performance requirement of the drain pipe 4, then a J-shaped pipe section is formed at the portion of the drain pipe 4 between the starting bending position in the wall and the surface of the outer wall 5, and in order to fix the J-shaped pipe section, the hard pipe section is correspondingly arranged in a J shape.

According to an embodiment of the present utility model, the compressor 2 may also be disposed outside the wall 5, and a support plate 51 or a bracket for accommodating the compressor 2 is disposed outside the wall, and the compressor 2 is mounted to the support plate 51 or the bracket.
