High frequency heating apparatus and electromagnetic wave detector for use in high frequency heating apparatus

摘要

57 A high frequency heating apparatus and an electromagnetic wave detector for use in the high frequency heating apparatus, which are so arranged to estimate the state of a food article placed in a heating chamber through detection of microwaves within the heating chamber. By devising a position of an antenna and a method of processing signals of the microwaves as detected, it becomes possible to effect detection of microwaves extremely stably and at high reliability.
