To prevent increase in power consumption and to prevent idling noise of a drainage pump during drainage and dewatering.SOLUTION: In an operation step, a flow rate of drainage water flowing in a connection hose 21 for connecting an intake 17 and a drainage pump 20 provided at a lower part on the back surface side of a water tub 11 is detected by drainage water flow rate detection means 18, and in the case where the drainage water flow rate becomes equal to or less than a predetermined value, the drive of the drainage pump 20 is temporarily stopped, and in the case where the drainage water flow rate becomes equal to or greater than a predetermined value, the drainage pump 20 is driven again. Thereby, power consumption is not increased, and generation of annoying idling noise of the drainage pump 20 can be prevented.SELECTED DRAWING: Figure 2 【課題】排水、脱水時に、電力消費を増加させず、排水ポンプの空転異音も防止すること。【解決手段】運転行程において、水槽１１の背面側下部に設けた取水口１７と排水ポンプ２０とを接続する接続ホース２１内を流れる排水の流量を、排水流量検知手段１８が検知し、その排水流量が、所定値以下になった場合に、排水ポンプ２０の駆動を一時停止し、排水流量が所定値以上になった場合に、再び排水ポンプ２０を駆動させる構成とすることにより、電力消費を増加させることなく、また、排水ポンプ２０の不快な空転異音の発生を防止することができる。【選択図】図２
