ABSTRACT:
A turntable drive mechanism for a microwave oven having an oven-defining structure having a bottom wall and a hingedly supported door for selectively closing and opening an access opening leading into the interior of the oven-defining structure. The turntable drive mechanism has a turntable assembly removably positioned on the bottom wall for rotation about its own center through a plurality of rollers situated between the turntable assembly and the bottom wall, and a plurality of magnets. Cooperating with these magnets carried by the turntable assembly are magnets carried by a rotary carriage driven by a drive unit in one direction and situated below the bottom wall and externally of the oven-defining structure. Rotation of the turntable assembly is induced by rotation of the rotary carriage by the effect of magnetic forces of attraction developed through the bottom wall between the magnets on the turntable assembly and the magnets on the rotary carriage.
