Abstract
A microwave oven has a cooking chamber in which a tray is provided for supporting food to be cooked. The tray is rotatable and can be raised and lowered. Cooking can be performed by microwaves and/or an electric resistance heater disposed in the cooking chamber. A sensor disposed in the cooking chamber detects a condition wherein food on the rising tray is at a height corresponding to that of the heater. In response to the sensing of such a condition the heater is turned off, a mechanism for raising the tray is also turned off, and a warning is emitted.
