DETAILED DESCRIPTION

[0039] The following is combined with Figure 1-7 This application is described in further detail.

[0040] The present application discloses a dehumidifier, referring to Figure 1 , including a shell 1, on which an air inlet 11 is provided, one side of the air inlet 11 is used for air intake, an evaporator 21 and a condenser 22 are provided at a position opposite to the air inlet 11 inside the shell 1, the condenser 22 is located on a side of the evaporator 21 away from the air inlet 11, so that the airflow first reaches the evaporator 21 from the air inlet 11 and then passes through the condenser 22; a water tank 23 is provided below the evaporator 21, the water tank 23 can be detachably installed in the shell 1, and the water tank 23 is used to hold liquid water condensed by the evaporator 21, and is convenient for removal. A fan 24 is provided on the side of the condenser 22 facing away from the evaporator 21, and the fan 24 is used to provide power for the airflow; a compressor 25 is also provided in the shell 1, and the compressor 25 is connected to the evaporator 21 and the condenser 22. On the one hand, the temperature of the evaporator 21 is maintained at a low level, and on the other hand, the airflow passing through the condenser 22 can cool the internal refrigerant and reduce the power consumption of the compressor 25; at the same time, it can also appropriately restore the lowered temperature of the evaporator 21 and reduce the impact of the dehumidifier on the indoor temperature.

[0041] refer to Figure 2 The evaporator 21 and the condenser 22 are both composed of a refrigerant tube 26 and a heat conducting plate 27. A plurality of heat conducting plates 27 are arranged in parallel and at intervals. The distance between two adjacent heat conducting plates 27 is 3-8 mm. The heat conducting plates 27 are arranged perpendicular to the refrigerant tube 26, so that the refrigerant tube 26 is vertically penetrated on a plurality of heat conducting plates 27. The refrigerant tube is in contact with the heat conducting plate 27, which is used to quickly disperse the heat in the refrigerant tube through the heat conducting plate 27 so that the airflow can quickly exchange heat when passing between adjacent heat conducting plates 27. The heat conducting plates 27 are parallel to the direction of the airflow. When the airflow passes through the grille provided at the air inlet 11, impurities in the air can be filtered once. However, due to the limitation of ventilation volume and power of the fan 24, the filtering effect of the grille is limited. Therefore, when there is liquid water on the heat conducting plate 27, it is easier to stick to fine dust. If the dust is not cleaned in time, it is easy to reduce the heat exchange between the heat conducting plate 27 and the airflow, thereby reducing the efficiency of liquefying water in the air. At the same time, due to the small distance between two adjacent heat conducting plates 27, it is usually difficult to clean the evaporator 21 and the condenser 22.

[0042] refer to Figure 2 A box body 3 is arranged outside the evaporator 21 and the condenser 22, and the box body 3 is open on the side facing the air inlet 11. The box body 3 includes a top plate 31, a side plate 32, a back plate 33 and a bottom plate 34. The bottom plate 34 is located below the evaporator 21 and the condenser 22. The bottom plate 34 is used to receive water. A downpipe 35 is connected to the lower part of the bottom plate 34. The downpipe 35 is used to be inserted into the water tank 23 or directly connected to the outside of the housing 1 for direct discharge. The top plate 31 is located above the evaporator 21 and the condenser 22 and is arranged parallel to the bottom plate 34. The upper side of the back plate 33 is connected to the top plate 31, and the lower side is connected to the bottom plate 34; the back plate 33 is perpendicular to the direction of the airflow; the back plate 33 is used to install the fan 24; two side plates 32 are provided, and the two side plates 32 are parallel to the heat conducting plate 27, and the side plates 32 are connected to the top plate 31, the back plate 33 and the bottom plate 34, so that the box body 3 is sealed at the connection between the top plate 31, the side plates 32, the back plate 33 and the bottom plate 34.

A sealing plate 4 is provided on the side of the back plate 33 facing the inside of the box body 3, and the sealing plate 4 is connected to a driving device 5, and the sealing plate 4 is opened or closed by the driving device 5. The sealing plate 4 is a semicircular structure, and a rotating shaft 41 is fixedly provided on the back plate 33 and above the through hole 331; the sealing plate 4 is rotatably connected to the rotating shaft 41; when the sealing plate 4 rotates around the rotating shaft 41, the sealing plate 4 can rotate to be staggered with the position of the through hole 331, so that the sealing plate 4 opens the through hole 331. The driving device 5 includes a driving screw 51, a driving motor 52, a slider 53 and a connecting rod 54. The driving motor 52 is fixed on the back plate 33. The axis of the driving motor 52 is vertically arranged and located directly above the rotating shaft 41. The slider 53 is threadedly connected to the driving screw 51. The driving screw 51 is coaxially fixed to the output shaft of the driving motor 52. Two connecting rods 54 are provided and are correspondingly arranged on both sides of the driving screw 51. One end of the connecting rod 54 is hinged on the slide, and the other end is hinged on the sealing plate 4. The two connecting rods 54 are arranged one by one with the two sealing plates 4. When the fan 24 is working, the driving motor 52 drives the driving screw 51 to rotate, so that the slider 53 moves upward, and then the two sealing plates 4 can be opened, so that the airflow enters the fan 24 from the position of the through hole 331. When the fan 24 is not working, the driving motor 52 is reversed to rotate the sealing plate 4 downward to the position covering the through hole 331, so that the sealing plate 4 closes the through hole 331.
