MICROWAVE HEATING DEVICE

摘要

A microwave heating apparatus includes a microwave generation part 10 using a semiconductor element, and first and second heating chambers 100a, 100b to each of which a microwave generated in the microwave generation part is fed. A reflected microwave returned from at least one of the first and second heating chambers 100a, 100b to the microwave generation part is transmitted to the other heating chamber by a circulation type non-reciprocal circuit 118, so that generated power of the microwave generation part is substantially completely consumed upon heating of an article to be heated.
