Abstract
With an automatic washer embodying this invention, a stirring blade member is rotatably provided in a basket set in a tub. A torque of a motor is transmitted to the stirring blade member by means of a drive transmission. A water supply control system is set in a central processing unit. Where wash water is filled in the tub to a predetermined or standard level, then a water valve is closed. A number of rotations of the stirring blade member in the wash water in which material of washing is dipped is detected by a rotation detector. A length of time for which the water valve is to be left open is determined from the number of rotations of the stirring blade member. The water valve is left upon for a calculated length of time.
