US Patent:

7264188, Sep 4, 2007

Filed:

Nov 29, 2005

Appl. No.:

11/164585

Inventors:

Scott W Anderson - Racine WI, US
Steven P Hanson - Racine WI, US

Assignee:

Emerson Electric Co. - St. Louis MO

International Classification:

B02C 23/36

US Classification:

241 4601, 241 46013

Abstract:

A baffle for a food waste disposer includes a pleated portion with pleats that define an opening therethrough for equalizing pressure in the food waste disposer above and below the baffle. Water passing over the opening creates a venturi to pull air out of the high-pressure environment inside the grinding portion of the food waste disposer.

Assignee:

Emerson Electric Co. - St. Louis MO

International Classification:

B02C 23/36

US Classification:

241 46013

Abstract:

A grinding mechanism for a food waste disposer includes a grinding ring defining a plurality of window openings therethrough. A backing member receives the grinding ring and defines a plurality of cavities therein corresponding to the window openings. A plurality of stacked disks form a rotatable shredder plate that is situated to rotate relative to the grinding plate.

Appl. No.:

11/750480

Inventors:

Thomas R. Berger - Racine WI, US
Steven P. Hanson - Racine WI, US

Assignee:

Emerson Electric Co. - St. Louis MO

International Classification:

B02C 19/00

US Classification:

241 325, 241 46015, 241 46016

Abstract:

A switching mechanism for a food waste disposer is provided having a plastic one-piece housing that engages an external surface of the food waste disposer by snapping thereto. The switching mechanism also contains a switch capable of enabling operation of the food waste disposer in response to an interlock device positioned within the drain opening. Also provided is a method for converting a continuous feed waste disposer into a batch feed waste disposer. The switching mechanism includes a plug having a male end and a female end that can receive the electrical plug from the continuous feed waste disposer.

Appl. No.:

11/702476

Inventors:

Steven P. Hanson - Racine WI, US

Assignee:

Emerson Electric Co. - St. Louis MO

International Classification:

B02C 4/32
B02C 23/36

US Classification:

241 33, 241 46013

Abstract:

A food waste disposer system includes a grinding mechanism. The grinding mechanism includes a stationary grind ring and a rotatable shredder plate assembly. A detector is connected to the grinding mechanism to detect the presence of a foreign electrically conductive object in the grinding mechanism. In an aspect, the detector detects that a foreign electrically conductive object is in the grinding mechanism upon sensing that an electrical circuit has been completed between the stationary grind ring and the rotatable shredder plate.

International Classification:

B02C 23/36

US Classification:

241 46016, 241 46014, 241 46015

Abstract:

A food waste disposer includes a housing defining an inlet opening and a grinding mechanism driven by a motor for grinding food waste received into the housing through the inlet opening. An annular retaining collar has one end for connecting to a sink opening, via a standard sink mount, for example. An annular elastomeric coupler is situated about the opposite end of the annular retaining collar and connected to the housing for vibrationally isolating the annular retaining collar from the housing. The primary loading on the elastomeric material is in shear. Elastomeric materials in shear are particularly effective in absorbing both vibration and shock loads.
