<P>PROBLEM TO BE SOLVED: To provide a microwave heating device uniformly and efficiently irradiating a heated object with microwave without using a rotating mechanism. <P>SOLUTION: In an applicator 10, a heated object 12 such as a foodstuff is placed on the top face of a metal table 11 in a minimum capacity. A conically cut fluororesin spacer 13 is disposed in the upper part of the heated object 12. The applicator 10 is constituted so that the heated object 12 is irradiated with the microwave synthesized in a T-type waveguide 1 through a conically cut silicone resin spacer. Thus, the synthesized microwave transmitted from the T-type waveguide 1 while having an electric field direction difference of 90 degrees is refracted by wavelength-contracting action of the silicone resin spacer, and the area of the heated object 12 is concentrically and uniformly irradiated with the synthesized microwave. Accordingly, the heated object 12 can be uniformly and efficiently heated without providing a turntable and the like. <P>COPYRIGHT: (C)2013,JPO&INPIT |
