Abstract
A stirring assembly includes a turntable configured to rotate about a central axis. A cooking vessel is configured to engage a top surface of the turntable. A bar is disposed proximate a bottom surface of the turntable. The bar maintains a fixed position relative to the turntable. A stirrer is magnetically attracted to the bar. The stirrer is configured to generally maintain a fixed orientation within the cooking vessel as the cooking vessel rotates with the turntable.
Claims18
A stirring assembly comprising:
- a turntable configured to rotate about a central axis;
- a cooking vessel configured to engage a top surface of the turntable;
- a bar disposed proximate a bottom surface of the turntable, wherein the bar maintains a fixed position relative to the turntable;
- and
- a stirrer including a vertically-extending frame that defines an open cavity and which is magnetically attracted to the bar, the stirrer including a first magnet encapsulated by a polymeric member at a first corner of the frame and spaced a predetermined distance from a second magnet encapsulated by a separate distinct polymeric member at a second corner of the frame, wherein the stirrer is configured to generally maintain a fixed orientation within the cooking vessel as the cooking vessel rotates with the turntable.

A stirring assembly for use with a cooking vessel comprising:
- a turntable operable between a rotating state and a non-rotating state, the turntable configured for rotation about an axis, wherein the turntable includes a top surface and a bottom surface;
- a bar disposed proximate the bottom surface of the turntable, wherein the bar maintains a fixed position while the turntable is in the rotating state;
- and
- a stirrer proximate the top surface of the turntable, wherein the stirrer includes a first magnet disposed proximate a first side segment and a second magnet disposed proximate a second side segment that includes a flexible wiping flange, and wherein the stirrer is configured to generally maintain a fixed orientation within said cooking vessel as said cooking vessel rotates with the turntable such that the stirrer does not rotate with said cooking vessel.

A microwave assembly comprising:
- a plurality of walls defining a cooking compartment;
- a turntable configured to rotate about a central axis, and further configured to support a cooking vessel;
- a bar operably coupled with at least one of the plurality of walls defining the cooking compartment, wherein the bar is disposed proximate a bottom surface of the turntable, and wherein the bar maintains a fixed position relative to the turntable;
- and
- a stirrer attracted to the bar, wherein the stirrer is configured to generally maintain a fixed orientation within the cooking vessel as the cooking vessel rotates with the turntable, and wherein the stirrer includes a first magnet covered by a polymeric member at a first bottom corner of the stirrer, the first magnet being spaced from a second magnet that is covered by a polymeric member having a flexible wiping feature and disposed at a second bottom corner of the stirrer.
