HIGH-FREQUENCY HEATING DEVICE OF DELECTRON RANGE

摘要

The stirrer (3) containing rectangular holes (1) and a reflecting plate (2) is placed under a wave guiding duct (4). The gap between the stirrer (3) and the wave guiding duct (4) is adjusted with &lgr;/4 or multiple number of it in which &lgr; is a frequency of the microwave so that the directional and reflecting microwaves compensate each other. The passed microwave through the hole (1) is propagated to the food uniformly.
