A disposal assembly includes a motor coupled to operate a grinding mechanism of a food waste disposer. A first switch is coupled to selectively inhibit the supply of power from a power source to a main winding of the motor, and a second switch is coupled to selectively inhibit the supply of power from the power source to a start winding of the motor. A control circuit is configured to close the first and second switches during an initial startup time period, detect a voltage of at least one of the windings, and open the second switch in response to detection of the voltage above a start voltage threshold value. The control circuit is also configured to subsequent to opening the second switch, close the second switch in response to detection of the voltage below a low voltage threshold value indicative of an excess load condition of the motor.

Control circuits for disposer motors

Systems and methods for controlling an operational status of a waste disposer are disclosed herein. In one example embodiment, a waste disposer assembly includes a waste disposer, a sprayer mechanism, and a switching system. The waste disposer is configured to be supported in relation to a sink. The sprayer mechanism is configured to be supportable in relation to the sink, is coupled at least indirectly to the sink by way of an extendable and retractable linkage, and includes an actuator mechanism that, upon being actuated, causes generation of a control signal. The switching system is supported in relation to the sink, is coupled at least indirectly to each of the sprayer mechanism and disposer, and is configured to operate so that, upon receiving the control signal from the actuator mechanism, a related signal is provided to the disposer causing the disposer to change or take on operational status.

System and method for controlling an operational status of a waste disposer

Grinding mechanisms for food waste disposers, and food waste disposers having grinding mechanisms are disclosed herein. The grinding mechanisms include a stationary grinding ring that includes a plurality of grater teeth, and a rotating shredder plate that includes at least one lug. The at least one lug may have at least a portion that is movable with respect to the top surface of the rotating shredder plate, or may be fin shaped.

Food waste disposer with grating ring

A control unit for a food waste disposer has a controller that determines operational status of the food waste disposer based on motor loading of an induction motor of the food waste disposer.
