To provide a washing and drying machine in which an increase in load of a compressor is suppressed by reducing dehumidification load of an evaporator in drying operation, thereby capacity of a heat pump unit when the dehumidification load increases during a latter half of the drying operation is maintained and the heat pump unit is made compact.
A circulating air circuit is formed by connecting a circulation air channel 7 comprising an air supply duct 7a, an exhaust duct 7b and a heat exchange duct 7c to an outer tub 3, and the evaporator 11 and a condenser 12 are placed in this order from an upstream side of circulation air inside the heat exchange duct 7c. Inside the exhaustion duct 7b on the upstream side of the evaporator 11, an endothermic heat exchanger 15 having a heat transfer tube 15a is provided. Cooling water is supplied for the endothermic heat exchanger 15 to cool the circulated air in the exhaustion duct 7b.
