MICROWAVE HEATING DEVICE

WIPO Patent Application WO/2016/006249

A1

　A rotating antenna (105a) includes a side wall surface (110) and a top surface (109) constituting a waveguide structure (108), and a horn part (113) for radiating microwaves in a heating chamber. The rotating antenna (105a) also has a flange part (112) provided on the edge of the side wall surface (110) so as to face a bottom surface (111) and so as to enclose the side wall surface (110), the bottom surface being one of the wall surfaces within the heating chamber. The flange part (112) has a choke part (117) for suppressing microwave leakage. Using the present configuration, it is possible to generate a region having relatively low impedance so as to enclose the side wall surface (110), and it is possible to strengthen the ability to suppress microwave leakage and the directionality of the microwave radiation in the rotating antenna (105a). As a result, when a portion of an article to be heated up on a dish is not intended to be warmed up, it is possible to heat up, in a concentrated manner, the region having a foodstuff that is to be warmed up and to mostly avoid heating up a foodstuff that is not to be warmed up.
