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.

The present invention relates to the field of food waste disposers, and, more particularly, to food waste disposers with embedded sprinkler assemblies.

Mounting systems for waste disposers such as food waste disposers, waste disposers employing such systems, and related methods, a mounting system includes a flange component having first and second ends and a tubular structure extending along a first axis between the ends. The mounting system also includes a mounting flange component having an inner edge defining at least in part an orifice extending through the mounting flange component and sized so that a first portion of the tubular structure including the second end can pass partly into or entirely through the orifice. When lugs of the mounting flange component are aligned with protrusions of the tubular structure and the tubular structure is positioned so that tips of the lugs are positioned between the protrusions and the first end, then the mounting flange component is secured in relation to the first flange component.

A disposal with above sink installation where the disposal can be inserted through a drain opening in a basin from above the basin. The disposal includes a housing, a grind assembly, a motor assembly, and a mount assembly. The mount assembly is operable to mount the housing to the drain opening in the basin. The mount assembly includes a flange and a securing mechanism. A diameter of the outer surface of the housing is less than a diameter of the drain opening in the basin. The housing is operable to be inserted through the drain opening in the basin from the top surface of the floor of the basin. The housing is operable to be secured to the drain opening in the basin from the bottom surface of the floor of the basin.

The present disclosure relates to a rotating cutter disc, comprising a grinding disc and an auxiliary member, wherein a grinding connecting hole is provided at a central portion of the grinding disc, the auxiliary member is mounted on the grinding disc, and an auxiliary connecting hole is provided at a central portion of the auxiliary member.

Food waste disposer systems and related systems for coupling food waste disposer systems having permanent magnet (PM) motors to electrical power sources, and related coupling and configuration methods, are disclosed herein. In at least one example embodiment, a food waste disposer system includes a PM motor, an AC-to-DC converter having AC input and DC output ports, a housing, a power cord connection structure supported at least indirectly upon the housing, an adapter, and a power cord including a first plug configured to be coupled to the connection structure. The disposer system can be selectively implemented either in a first installation environment including a wall outlet by way of coupling the first plug to the connection structure, or in a second installation environment including a hardwired power cable by coupling additional lead wires of the hardwired power cable to the adapter and further coupling the adapter to the connection structure.
