Abstract: An electric washing machine according to the present invention performs a washing process for washing laundry without the use of a detergent by generating water streams in an outer tub (2) containing an electrolyzed liquid produced through electrolysis by an electrolyzing device (31) when a zero detergent course is selected by a user. The electrolyzing device (31) is provided as a water treatment unit (60) attached to a lower portion of an outer side surface (66) of the outer tub (2), and includes a thin-box-shaped electrolyzing chamber (32), a pair of electrodes (33) supported at opposite edges thereof, and a pair of water communication paths (34, 35). The pair of water communication paths (34, 35) are disposed in a vertically juxtaposed relation to connect the outer tub (2) to the electrolyzing chamber (32) with the intervention of packings (81). Thus, an assembling operation and the like can conveniently be performed, and water can efficiently be electrolyzed for use in the washing process.

Abstract: An electric washing machine according to the present invention performs a washing process with the use of electrolyzed water. When the level of supplied water reaches an electrolyzing water level which is lower than a washing water level, energization of an electrolyzing device (31) is started. At this time, air is supplied into an electrolyzing chamber (32) by an air pump (89), so that water in the electrolyzing chamber (32) is caused to flow, thereby assisting efficient electrolysis of the water. The water thus electrolyzed has an enhanced cleaning capability thereby to improve the washing performance of the washing machine.
