ABSTRACT:
A washing-drying machine includes an inner tub having a rotating shaft and sustained rotatably in an outer tub suspended elastically in a cabinet, where an agitator disposed rotatably on an inner bottom of the inner tub. The washing-drying machine also includes a motor for driving the inner tub or the agitator and a warm-air-circulating pass having a heat exchanger cooled by a cooling section. The washing-drying machine further includes a controller for controlling processes including washing, rinsing, dehydrating and drying. The cooling section is formed of a water-cooling-section for cooling warm-air in the heat exchanger by supplying water, and an air-cooling-section for cooling an outer wall of the heat exchanger by blowing air. As a result, high dehumidification rate by improving heat-exchange efficiency of the heat can be obtained, and clothes are hardly damaged and electric power and the amount of water consumption can be saved.
