摘要：PROBLEM TO BE SOLVED: To provide a drain pump-driving method without impairing the draining capacity. SOLUTION: The washing machine includes: a drum 32 enclosed and rotatably disposed inside a water receiving tub 31; a motor 34 for rotating the drum 32; a drain valve 38 disposed in a drain 37 in the water receiving tub 31; a drain pump 40 for draining water from the water receiving tub 31; a bellows pipe 39 connected to the drain valve 38 and the drain pump 40; a drain hose 47 for draining the water from the drain pump 40 to an appropriately upper high place; and a control means 45 for controlling washing, rinsing, dewatering and other steps. The control means 45 starts driving the drain pump 40 after the elapse of a prescribed time from the opening of the drain valve 38 when draining is started, and closes the drain valve 38 after the elapse of a prescribed time from the stop of the drain pump 40 when draining is stopped. With this structure, air within the drain pump 40 can be removed during a fixed period of time, so that impairment of the draining capability can be prevented. COPYRIGHT: (C)2011,JPO&INPIT
