摘要： A microwave oven adapted to radiate microwaves of mutually reverse phases to minimize impedance variation of a waveguide in response to load change of foodstuff, thereby maintaining an output of the microwave at a constant level regardless of load amount of the foodstuff and maintaining an electric field distribution in a cavity at a constant level as well.

摘要： A microwave oven has a cooking chamber in which a vertically movable turntable is disposed. During the onset of a cooking operation, a control mechanism automatically raises the turntable in step-by-step fashion, and the amount of high frequency waves reflected from the cooking chamber is detected at each vertical position of the turntable. Then, the vertical position of the turntable at which the detected amount of reflective frequency was the lowest is determined, and the turntable is set at that position to continue the cooking operation. If the detected amount of reflective frequency changes, a new vertical position of the turntable at which the amount of reflective frequency is lowest, is re-determined, and the turntable is set at that new position.
