  • Patent number: 3948064
    Abstract: An automatic clothes washing machine of a single-tub construction with water level sensing and liquid extraction features includes scoop conduits arranged symmetrically within the sump chamber of a reversely tapered tub i.e., divergent from top to bottom. Each scoop conduit has an opening in its end adjacent the outer wall of the sump chamber and is connected to a discharge line along the axis of the tub. When the tub spins, liquid is forced radially outwardly and downwardly and exits through the scoop conduit openings into the discharge line while maintaining a dynamic balance of the tub. Liquid level control is regulated by a pressure sensitive valve means communicating with an air dome in an agitator portion of the tub.
