<P>PROBLEM TO BE SOLVED: To provide a washing machine capable of shortening operation time while keeping rinsing performance by shortening rest time of a circulation pump and improving drive rate. <P>SOLUTION: The washing machine comprises a water circulation system which is provided in a circulation path and circulates washing water inside a rotary drum 4 by a circulation pump 20 with variable rotational speed. In a rinsing step, the circulation pump 20 is driven at a first predetermined rotational speed before water level detection means 10 detects a water level and, after water supply means 7a starts supplying water and the water level detection means 10 detects that a water level becomes a predetermined water level or higher, the circulation pump 20 is driven at a second predetermined rotational speed higher than the first predetermined rotational speed, so that drive rate of the circulation pump 20 is increased and the rinsing efficiency by a circulation shower is improved. <P>COPYRIGHT: (C)2013,JPO&INPIT |
