MICROWAVE HEATING DEVICE Russian patent published in 2013 - IPC H05B6/68 

FIELD: electricity.

SUBSTANCE: microwave heating device includes a part of microwaves generation, where a semiconducting element is used, and the first and second heating chambers, in every of which microwaves are sent, generated in the part of microwaves generation. Reflected microwaves returned at least by one of the first and second heating chambers into the part of microwaves generation are sent into another heating chamber, using the non-return circuit of circulating type, so that the generated capacity of the microwaves generation part is substantially fully absorbed whenever an object is heated, which is intended for heating.
