Abstract
A turntable is provided for a microwave oven for rotating foodstuffs placed thereon and effecting uniform heating of the foodstuffs. The turntable includes a base, a rotatable table for receiving foodstuffs, and drive means mounted on the base for rotatably driving the table. The base, table, and drive means are incorporated in a portable, freestanding structure which is adapted for placement and removal from a microwave oven.
Claims15
A portable self-contained turntable for rotating foodstuffs in a microwave oven cavity comprising:
- a base for engaging a load supporting surface in the oven cavity;
- a table for receiving foodstuffs, said table being rotatably mounted on said base;
- and
- drive means mounted on said portable self-contained turntable for rotatably driving said table from within the oven cavity, said drive means comprising:
- an energy storing spring;
- a spring storage reel, said spring being stored on said storage wheel;
- an output reel secured to said table and centered on the axis of rotation of said table;
- and
- an escapement mechanism connected to said output reel, said escapement comprising:
- a gear step-up transmission;
- and
- means for limiting the rotation of said transmission and thus regulating the speed of said turntable, said means for limiting rotation limiting movement of said transmission to a step-like motion.
In a microwave oven having a cooking cavity where foodstuffs are irradiated with electromagnetic radiation;
- the improvement comprising:
- a portable self-contained turntable for rotatable foodstuffs within said microwave oven cooking cavity said turntable having:
- a base for engaging a load supporting surface in the oven cavity;
- a table for receiving foodstuffs, said table being rotatably mounted on said base;
- and
- drive means mounted on said portable self-contained turntable for rotatably driving said table from within said microwave oven cavity without a physical connection extending outside of said microwave oven cavity, said drive means comprising:
- an energy storing spring;
- a spring storage reel, said spring being stored on said storage wheel;
- an output reel secured to said table and centered on the axis of rotation of said table;
- and
- an escapement mechanism connected to said output reel, said escapement mechanism comprising:
- a gear step-up transmission;
- and
- means for limiting the rotation of said transmission and thus regulating the speed of said turntable, said means for limiting rotation limiting the movement of said transmission to a step-like motion.

- an output reel mounted on said turntable;
- and
- an escapement mechanism connected to said output reel, said escapement comprising:
- a gear step-up transmission;
- and
- means for limiting the rotation of said transmission and thus regulating the speed of said turntable, said means for limiting rotation limiting movement of said transmission to a step-like motion.
