A drain port 19 is formed. The drain tank 20 is detachably attached to a lower portion of the main body case 11 below the drain port 19, and a full water switch 21 is provided on the upper rear side of the drain tank 20. A compressor 22 for compressing the refrigerant gas is disposed behind the drain tank 20 in the lower part of the main body case 11.

In the dehumidifier 10 thus constructed, the refrigerant gas compressed by the compressor 22 is cooled by the radiator 15 to become a high temperature and high pressure liquid. The liquid refrigerant is dried by a dryer (not shown) and then a capillary tube (not shown).
The pressure is reduced by, and the cooler 14 is endothermic vaporized to cool the cooler 14. The mixed refrigerant, which has been vaporized in the cooler 14 to become a low-temperature refrigerant gas and a refrigerant liquid, is further completely vaporized in the pipe to become a refrigerant gas and is sucked into the compressor 21 to form a circulation refrigeration cycle system. ing. Therefore, the air sucked from the suction port 12 by the fan 16 and subsequently purified by the filter 13 is cooled by the cooler 14 to be cooled and dehumidified. That is, as the air is cooled by the cooler 14, the moisture in the air adheres to the cooler 14 and becomes dehumidified water, which is collected by the drain pan 17 and further collected by the water collecting portion 18.
