ABSTRACT:
A microwave oven includes a turntable disposed in a cooking chamber. The turntable is seated on rollers which are driven about horizontal axes to rotate the turntable. The rollers are mounted on elements that can be raised and lowered, whereby the turntable is raised and lowered while being rotated. A drive mechanism which raises and lowers the rollers is reversible whereby the turntable is rotated in a first direction while being raised, and in a second direction while being lowered. Position detectors sense when the turntable has reached maximum upper and lower positions for reversing the drive mechanism.
