Device.

Here, the dehumidifier uses a method of evaporating the refrigerant in a liquefied state from the ambient air by evaporating the refrigerant in the evaporator. As the refrigerant evaporates, the temperature of the evaporator is lowered and the temperature of the air passing through the evaporator is also lowered. Accordingly, as the temperature around the evaporator drops, the moisture contained in the air condenses and forms dew on the surface of the evaporator.

A compressor 21, a condenser 22 ), The evaporator (23), and the blowing fan (24).

FIG. 2 is an exploded perspective view of a dehumidifier according to Japanese Patent No. 1231278 (hereinafter referred to as "Prior Art 2"). As shown in FIG. 2, the dehumidifier of the prior art 2 is provided inside the main body 100, and includes a barrier 130 partitioning the inner space of the main body 100 back and forth.
