PROBLEM TO BE SOLVED: To solve the problem of deteriorated energy efficiency in feeding warm water by an electric heater or gas-fueled water boiler for heating washing water, resulting in an increased environmental load due to emission of carbon dioxide, while warm water is desirable to obtain cleaning force for eliminating contamination on clothing by washing. SOLUTION: The device comprises a water circulation circuit comprising a heat pump cycle composed of a compressor, a heater, and a cooler to exchange heat by cooling medium for heating washing water, and an air circulation circuit to heat and dehumidify clothing after completion of washing by means of the heat pump cycle. Flow passages are disposed in such a way that flow of cooling medium and flow of washing water are in facing directions to each other. COPYRIGHT: (C)2008,JPO&INPIT
