The structure of the dehumidifier will be described in detail with reference to the figures.
The dehumidifier comprises two parts 1, a first water receiver 2, a fan 3, a second water receiver 4, a compressor 5, a chassis 6 and a rear plate 7. The first water collector is formed by embedding a metal plate 2-2 into a water collecting tray 2-1 during injection molding, an upper fin 2-2-1 of the metal plate 2-2 is positioned in the water collecting tray 2-1, and a lower fin 2-2-2 of the metal plate 2-2 is positioned on the lower side of the water collecting tray 2-1.
The cold energy of the condensed water generated by the evaporator in the two device parts 1 when encountering cold can be effectively transferred to the lower fins 2-2-2 of the metal plate 2-2 through the upper fins 2-2-1 of the metal plate 2-2; meanwhile, under the action of negative pressure generated by the fan 3, air is sucked from an air inlet of the rear plate 7 and enters an air inlet channel formed by the first water receiver 2 and the second water receiver 4, the air is contacted with the lower fins 2-2-2 of the metal plate 2-2 to generate secondary condensation, and the generated condensed water flows into a water collecting tank 2-1-5 of the first water receiver 2 through the one-way water discharging nozzle 4-4; the fan 3 guides the cooled air into the accommodating cavity of the compressor 5, and the heat generated by the compressor 5 is rapidly dissipated from the heat dissipation hole 6-1 of the chassis 6 through forced heat dissipation.
The upper fins 2-2-1 and the lower fins 2-2-2 are arranged in plurality, so that the contact area can be increased to improve the cold exchange efficiency with condensed water in the water pan 2-1 and sucked air.
The first water receiver 2 comprises an air inlet 2-1-1, an air inlet channel 2-1-2, a mounting stud 2-1-3, a water inlet hole 2-1-4, a water collecting tank 2-1-5, a water discharging nozzle 2-1-6, a screw hole 2-1-7, a rib 2-1-8, a rib 2-1-9 and the like. The second water receiver comprises a mounting lug 4-1, a water collecting tank 4-2, an air outlet 4-3 and a one-way water discharging nozzle 4-4; the fan 3 comprises an air inlet 3-1, axial flow fan blades 3-2, an air outlet 3-3, limiting ribs 3-4 and mounting lugs 3-5.
The specific implementation process of the application is as follows:
the ribs 2-1-8 and the upper sides of the ribs 2-1-9 of the first water receiver support and limit the second water receiver 4, the side faces of the ribs 2-1-9 of the first water receiver 2 limit the left side of the second water receiver 4, the mounting studs 2-1-3 of the first water receiver 2 limit the front and back direction of the second water receiver 4, the mounting lugs 4-1 of the second water receiver are fixed to the mounting studs 2-1-3 of the first water receiver by screws, at the moment, the first water receiver and the second water receiver form an air inlet channel, and the one-way water discharge nozzle 4-4 of the second water receiver is inserted into the water inlet hole 2-1-4 of the first water receiver in an interference mode. The fan is positioned and limited through the action of the limiting ribs 3-4 and the ribs 2-1-8 of the first water receiver, the fan is fixed on the first water receiver through the matching of the mounting lugs 3-5 and the screw holes 2-1-7 of the first water receiver, at the moment, the air outlet 4-3 of the second water receiver is positioned in the air inlet 3-1 of the fan, and the left side of the fan plays a limiting role in facing the right side of the second water receiver. The space enclosed by the rear plate 7, the first water receiver and the chassis 6 forms an accommodating cavity of the compressor 6.

Under the same condition, the amount of the generated condensed water is increased, thereby improving the refrigeration energy efficiency of the dehumidifier. The fan guides the cooled air into the accommodating cavity of the compressor 5, and the heat generated by the compressor 5 is rapidly dissipated from the heat dissipation hole 6-1 of the chassis 6 through forced heat dissipation, so that the problems of overheat shutdown and long shutdown time of the compressor are solved. The working temperature of the compressor is reduced, the corresponding required input power is reduced, and the refrigeration energy efficiency of the dehumidifier can be further improved. Because of the foam material that second water collector used itself has the heat preservation effect, the temperature of compressor holding intracavity after forcing the heat dissipation simultaneously is lower, does not satisfy the required condition of condensation, consequently can solve the problem that water collector lower part secondary condensation drips and causes the electrical safety hidden danger.
