  • Patent number: 10362641
    Abstract: A microwave oven includes a waveguide having an E-bend structure with multiple openings disposed on a lateral face of a heating chamber that allow the waveguide to communicate with the heating chamber. The waveguide has a first section for propagating a microwave from a magnetron toward the heating chamber, and a second section having a wide plane that abuts an outer wall of the heating chamber. The openings include at least one circularly-polarized-wave opening for generating a circularly polarized wave. A cross section of the first section orthogonally intersects a tube axis of the first section projects virtually along the tube axis of first section and onto a lateral face of the heating chamber, and the circularly-polarized-wave opening is configured such that its center is located outside the resultant projected region.

  • Publication number: 20170171922
    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: 9585203
    Abstract: In a microwave heating device of the present invention, a heating-chamber input portion is adapted to direct, to a heating chamber, microwaves having propagated through a waveguide tube and having passed through the positions where microwave radiating portions are formed, thereby realizing a state where progressive waves are dominant among the microwaves propagating through the waveguide tube, so that the microwave radiating portions are caused to radiate, to the inside of the heating chamber, microwaves based on the progressive waves propagating through the waveguide tube. This enables uniformly heating an object to be heated, without using a rotational mechanism.
