Abstract

PROBLEM TO BE SOLVED: To improve drying efficiency for clothes, and reduce a drying time by laying a compression and heat releasing part for the refrigerant of a refrigerating device outside a drying chamber. SOLUTION: The wet air resulting from the dehumidification of wet clothes C is drawn into an upper housing 31a via the wet air suction port 32 of a unit housing 31 and dehumidified through an evaporator 36, thereby becoming the dry air due to exposure to the circulating air. In this case, a condenser 42 as a compression and heat releasing part is installed within a washing machine housing chamber B, and prevented from coming in contact with the heated air, thereby preventing a drop in the radiation effect of the condenser 42. Consequently, the evaporator 36 is sufficiently cooled and the dehumidification function thereof does not drop. The dry air is thereafter blown from a hot air blowing outlet 33 on the operation of a hot air supply fan 39, in such a state as heated to desired temperature with a hot air heater 38. Then, the wet clothes C in a drying chamber A are dried via a continuous air flow.
