Embodiment Construction

[0039] figure 2 is a block diagram of a control unit 200 for monitoring the operational status of a food waste disposer having an induction motor, such as the food waste disposer 100, wherein the motor 34 is an induction motor, the control unit 200 using AC power according to an aspect of the present disclosure The phase difference between the voltage and current of the sensor powers the induction motor of the food waste disposer. As used herein, "AC" is alternating current, "DC" is direct current, "VAC" is AC voltage, and "VDC" is DC voltage. The control unit 200 has AC power inputs 202, 204 coupled to an AC power source 206, wherein the input 202 - the hot side input 202 - is coupleable to the hot side of the AC power source 206, and the input 204 - the common side input 204 -Couplable to the neutral side of an AC power source 206, which may for example be a 120VAC power source in countries where 120VAC is the standard voltage for household electricity or 240VAC in countrie...

Abstract

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

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Patent Application No. 16 / 673,921, filed November 4, 2019, which claims the benefit of U.S. Provisional Application No. 62 / 773,508, filed November 30, 2018. The entire disclosure of the above application is incorporated herein by reference. technical field [0003] The present disclosure relates generally to food waste disposers and, more particularly, to monitoring food waste disposer operation by sensing the motor load of an induction motor of the food waste disposer. Background technique [0004] This section provides background information related to the present disclosure which is not necessarily prior art. [0005] This type of food waste disposer, which is disposed under the sink and installed to the drain of the sink, generally includes a food conveying section, a motor section, and a grinding section. The grinding part is disposed between the food conveying part and t...
