However, when the dehumidifier is used in a low-temperature environment, the heat exchange system of the dehumidifier is frosted, the frosting is inevitable, the dehumidification effect is influenced during the frosting, and certain harm is generated to internal accessories of the dehumidifier; in addition, during defrosting of the dehumidifier, more water is generated, and short-circuit accidents are easy to happen if the water is not properly treated.

In order to solve the defects of the prior art, people have long searched for and put forward various solutions. For example, the chinese patent document discloses a novel automatic defrosting dehumidifier [201820293471.X ], which comprises a housing, wherein an exhaust fan is fixedly connected to the inner wall of the left side of the housing inner cavity, a compressor is fixedly connected to the bottom wall of the housing inner cavity, fixing plates are fixedly connected to the front side and the rear side of the right side of the bottom wall of the housing inner cavity, a condenser and an evaporator are respectively and fixedly connected between the two fixing plates, and an exhaust pipe and an air return pipe are respectively communicated with the surface of the compressor.

The scheme solves the problems of non-automation and poor defrosting and dehumidifying effects of the defrosting and dehumidifying machine to a certain extent, but the scheme still has defects, for example, a better moisture collecting device is not arranged, when the amount of frost is more or the defrosting force is larger, more moisture can be generated, and the defrosting and dehumidifying machine is damaged due to improper treatment.
