In some embodiments of the present invention, the distance between any two water condensation pipes 410 of the middle part 402 is the same or different.
For example, the distance between any two water condensation pipes 410 of the middle part 402 can be the same, so that the water condensation pipes 410 of the middle part 402 have simpler structure and are convenient to process and manufacture; or, the distance between the adjacent water condensation pipes 410 is gradually reduced near the center of the auxiliary condensation pipe in the up-down direction, so that the heat exchange between the water condensation pipe 410 near the middle part 402 and the gas in the first air duct is more sufficient, and the dehumidification efficiency of the dehumidifier 1 is higher.
In some embodiments of the present invention, as shown in fig. 4 to 9, the middle portion 402 has a central plane in the up-down direction, the water condensation pipe 410 of the middle portion 402 is symmetrically disposed about the central plane, that is, no matter the distance between any two water condensation pipes 410 of the middle portion 402 is the same or different, the structure of the water condensation pipe 410 of the middle portion 402 can be simplified by symmetrically disposing the water condensation pipe 410 of the middle portion 402 about the central plane, so that the structure of the auxiliary water condensation device 400 is simpler, and the processing is more convenient.

The dehumidifier 1 in the present application performs a refrigeration cycle of the dehumidifier 1 by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.
The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.
The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The dehumidifier 1 can adjust the temperature and humidity of the indoor space throughout the cycle.
