Abstract

In a washer-dehydrator, an eccentrically set pulsator is driven through a rotation moment-transmitting mechanism, and, even in case washing water streams containing foreign matter are drawn below the pulsator by the action of pumping blades mounted on the underside of the pulsator. The operation of the rotation moment-transmitting mechanism is not obstructed by the foreign matter, but circulating water streams can be smoothly produced to trap foreign matter retained in the washing water.
