  • Multi-outlet fluid flow system for an appliance incorporating a bi-directional motor
    Patent number: 10557469
    Abstract: A drain pump for an appliance includes a single, self-starting, single-phase synchronous motor and a pump chamber having an inlet and first and second outlets. The first outlet is a drain outlet and the second outlet is a recirculation outlet. An impeller is disposed within the pump chamber and is selectively and bi-directionally driven by the single-phase synchronous motor. Rotation of the impeller in a first direction directs fluid from the inlet toward the drain outlet and away from the recirculation outlet. Rotation of the impeller in the second direction directs the fluid from the inlet toward the recirculation outlet and away from the drain outlet.
