  • Patent number: 11153943
    Abstract: A rotating antenna (105a) includes: a ceiling surface (109) and a side-wall surface (110) that constitute a waveguide structure (108); and a horn (113) that radiates a microwave into a heating chamber. The rotating antenna (105a) further includes a flange (112) that is formed on a periphery of the side-wall surface (110) so as to face a bottom surface (111), which is an inner wall surface of the heating chamber, and so as to surround the side-wall surface (110). The flange (112) has choke sections (117) that reduce a leakage of the microwave. This configuration can generate a relatively low impedance region so as to surround the side-wall surface (110), thereby enhancing a leakage reducing performance of the rotating antenna (105a) and increasing directivity of the microwave radiated from the rotating antenna (105a).

  • Patent number: 10939512
    Abstract: The present invention includes a directional coupler that detects at least part of a reflected wave inside a waveguide. When an object to be heated is absent, a reflected wave is strong, because there is nothing to absorb a microwave. When the object is present, the reflected wave is weak, because the microwave is absorbed by the object. As a quantity of the object becomes greater, a larger amount of microwave is absorbed by the object, and thus the reflected wave is weakened. It is thus possible to determine the quantity of the object from a reflected wave detection amount detected by the directional coupler without using a detector that detects a load.

  • Patent number: 10912165
    Abstract: The present invention has a configuration of controlling a motor so as to stop a radiation antenna when the radiation antenna faces in a direction in which a reflected wave detection amount is minimized and to stop the radiation antenna when the radiation antenna faces in a different direction different from the direction in which the reflected wave detection amount is minimized. According to this configuration, first, the radiation antenna stops when facing in the direction in which the reflected wave detection amount is minimized. This extends a heating time under the most efficient condition, improving a heating efficiency in comparison with when the radiation antenna constantly rotates. Second, the radiation antenna stops when facing in the different directions. This causes uneven heating when the radiation antenna faces in the direction in which the reflected wave detection amount is minimized as well as when the radiation antenna faces in the different directions.

  • Patent number: 10880960
    Abstract: There are provided heating chamber, and reflection angle control device provided on upper wall configuring at least part of walls of heating chamber and configured to control a reflection angle of a microwave to control standing wave distribution in heating chamber. Reflection angle control device controls the reflection angle of the microwave when the microwave radiated from microwave radiation device is not directly absorbed into heating target but is reflected by the wall. Standing wave distribution in heating chamber can thus be controlled to be different from ordinary distribution for improvement in local heating performance.
