Abstract
Abstract A shelf structure is provided for use with a turntable in a microwave oven. The shelf structure includes a food-supporting platform and a base which rests on the table of the turntable. A first food product is placed on the turntable, and a second food product is placed on the platform above the first. When microwave energy is introduced toward the top of the oven cavity, the food product on the platform is exposed to more of the energy than is the food product on the turntable, and therefore tends to cook at a faster rate.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
173 words
In apparatus for use in cooking food products in a microwave oven: a portable turntable having a base adapted to rest on a supporting surface in the oven cavity, a table rotatively mounted on the base, and a drive motor for rotating the table about a vertically extending axis, said turntable being adapted to be freely inserted into and removed from the cavity of the microwave oven, and a shelf structure removably mounted on the turntable having a horizontally extending platform for receiving a first food product and a plurality of legs depending from the platform and adapted to rest on the table of the turntable with the platform being spaced above the table by a distance great enough to permit a second food product to be heated on the table beneath the platform and the legs being spaced apart with an opening between two of the legs large enough to permit the second food product to be placed on and removed from the table without removing the shelf structure from the turntable.
