Abstract
A food waste disposer comprises an upper food conveying section, a lower motor section, and a central grinding section disposed between the food conveying section and the motor section. The motor section includes a motor imparting rotational movement to a motor shaft. The food conveying section includes a first injection-molded plastic housing that forms an inlet at its upper end for receiving food waste. The food conveying section conveys the food waste to the central grinding section. The grinding section includes a grinding mechanism having a portion mounted to the motor shaft. The grinding mechanism grinds the food waste into particulate matter. The central grinding section includes a second injection-molded plastic housing encompassing the grinding mechanism and integrally formed with the first injection-molded plastic housing. The motor is enclosed within a motor housing having a stamped metal upper end frame. The upper end frame separates the grinding mechanism from the motor and is separately formed from the first and second plastic housings.
