HIGH-FREQUENCY HEATING DEVICE

摘要

PURPOSE: To maintain uniform heat distribution over a foodstuff, regarding a high-frequency heating device. CONSTITUTION: An electromagnetic wave outputted from a magnetron 1 is transmitted from the bottom of a heating chamber 4 through a waveguide 2 and a rotary antenna 6. Furthermore, the antenna 6 is driven, depending on the status of a foodstuff 5 detected with a weight sensor 13 or a temperature sensor 5. The directivity of the electromagnetic wave is thereby controlled for maintaining uniform heat distribution.
