MICROWAVE HEATING DEVICE

摘要

In order to radiate microwaves from a waveguide tube to a whole area from end to end of a radiation area within a heating chamber, and to heat uniformly an object to be heated without using a driving mechanism, a microwave heating device of the present invention includes openings 105, 106 for radiating the microwave from the waveguide tube 104 to the inside of the heating chamber 102. The heating chamber 102 includes a radiation area which has a length of approximate twice an in-tube wavelength in a propagation direction of the waveguide tube 104. Also, the openings 105, 106 are arranged to have an interval of approximate the in-tube wavelength in the propagation direction of the waveguide tube 104, and are symmetrically arranged to a center line which intersects perpendicularly to the propagation direction in the radiation area.
