Abstract: There are provided an outer tub suspended elastically in an enclosure, an inner tub for containing clothes supported rotatably within the outer tub, and a rotary impeller held rotatably on an inner bottom portion of the inner tub. The inner tub and/or the rotary impeller are driven by a motor. A drying blower delivers air into the inner tub, and a heater heats the air delivered by the blower unit. A controller controls operation of the motor, the drying blower, the heater, and the like, thereby controlling each process of washing, rinsing, hydro-extraction, and drying. In the hydro-extraction process, the controller drives the inner tub while also driving the drying blower to maintain delivery of air into the inner tub.
