Food waste disposer with grating ring
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.
1 . A food waste disposer comprising:
a housing bounding:
a food conveying section;
a motor section comprising a motor that rotates a shaft;
a grinding section located between the food conveying section and the motor section; and
a grinding mechanism within the grinding section, the grinding mechanism comprising a rotating shredder plate attached to the shaft at a center of the rotating shredder plate, the rotating shredder plate including at least one rotatably attached lug, wherein the at least one rotatably attached lug has a base that abuts a top surface of the rotating shredder plate, a face plate that is connected to the base, and a connector that rotatably connects the base to the top surface, and wherein the face plate has a first section connected to the base at an angle and a second section extending radially outward from the first section with respect to the connector, the second section overhangs the rotating shredder plate such that the second section is spaced above the top surface of the rotating shredder plate by a distance, the second section is positioned to rotate over a center point of the rotating shredder plate via the connector, and the distance is sized such that the second section is rotatable over the center point and above a structure that connects the rotating shredder plate to the shaft.
2 . The food waste disposer of claim 1 , wherein the rotating shredder plate includes at least two rotatably attached lugs that are each rotatably attached to the rotating shredder plate.
3 . The food waste disposer of claim 1 , wherein the grinding section further comprises a stationary grinding ring including a plurality of rows of grater teeth, wherein each row of grater teeth has at least one grater tooth.
4 . The food waste disposer of claim 1 , wherein the face plate of the at least one rotatably attached lug is connected to the base of the at least one rotatably attached lug at an angle of 90°.
5 . The food waste disposer of claim 1 , wherein the face plate of the at least one rotatably attached lug has a first end positioned along the first section that is curved and a second end positioned along the second section that extends towards an outer edge of the rotating shredder plate.
6 . The food waste disposer of claim 5 , wherein the first end of the face plate extends from a side of the base that is closest to a center of the rotating shredder plate.
7 . The food waste disposer of claim 5 , wherein the second end has a flat outermost edge.
8 . The food waste disposer of claim 5 , wherein the first end extends from a side of the base that is closest to the outer edge of the rotating shredder plate.
9 . A grinding mechanism for a food waste disposer, the grinding mechanism comprising:
a rotating shredder plate attached to a shaft at a center of the rotating shredder plate, the rotating shredder plate including at least one rotatably attached lug, wherein the at least one rotatably attached lug has a base that abuts a top surface of the rotating shredder plate, a face plate that is connected to the base, and a connector that rotatably connects the base to the top surface, and wherein the face plate has a first section connected to the base at an angle and a second section extending radially outward from the first section with respect to the connector, the second section overhangs the rotating shredder plate such that the second section is spaced above the top surface of the rotating shredder plate by a distance, the second section is positioned to rotate over a center point of the rotating shredder plate via the connector, and the distance is sized such that the second section is rotatable over the center point and above a structure that connects the rotating shredder plate to the shaft.
10 . The grinding mechanism of claim 9 , wherein the rotating shredder plate includes at least two rotatably attached lugs that are each rotatably attached to the rotating shredder plate.
11 . The grinding mechanism of claim 9 , further comprising a stationary grinding ring including a plurality of rows of grater teeth, wherein each row of grater teeth has at least one grater tooth.
12 . The grinding mechanism of claim 9 , wherein the face plate of the at least one rotatably attached lug is connected to the base of the at least one rotatably attached lug at an angle of 90°.
13 . The grinding mechanism of claim 9 , wherein the face plate of the at least one rotatably attached lug has a first end positioned along the first section that is curved and a second end positioned along the second section that extends towards an outer edge of the rotating shredder plate.
14 . The grinding mechanism of claim 13 , wherein the first end of the face plate extends from a side of the base that is closest to a center of the rotating shredder plate.
15 . The grinding mechanism of claim 13 , wherein the second end has a flat outermost edge.
16 . The grinding mechanism of claim 13 , wherein the first end extends from a side of the base that is closest to the outer edge of the rotating shredder plate.
17 . The food waste disposer of claim 1 , wherein the first section is oriented at 90° relative to the base.
18 . The food waste disposer of claim 17 , wherein the first section and the second section are coplanar.
19 . The grinding mechanism of claim 9 , wherein the first section is oriented at 90° relative to the base.
20 . The grinding mechanism of claim 19 , wherein the first section and the second section are coplanar.
