Publication number: 20140166645Abstract: 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.Type: ApplicationFiled: July 31, 2012Publication date: June 19, 2014Applicant: PANASONIC CORPORATIONInventors: Masafumi Sadahira, Daisuke Hosokawa, Koji Yoshino, Tomotaka Nobue, Yoshiharu Omori

Patent number: 5438183Abstract: A microwave oven includes a cavity in which food is accommodated, a magnetron for generating microwaves, and a waveguide to supply microwaves generated from the magnetron into the cavity. The waveguide has substantially a truncated cone configuration in which the cross sectional area at the cavity side is greater than the cross sectional area at the magnetron side, and an output antenna of the magnetron is disposed to project from the bottom of the waveguide at the magnetron side into the inner space of the waveguide. The microwave oven further includes a flat radiation antenna fixed in the inner space of the waveguide around the output antenna of the magnetron while maintaining distances from the waveguide and the output antenna of the magnetron in which no spark is generated. Therefore, the radiation area for emitting the microwaves is increased significantly to improve heating nonuniformity within the cavity.Type: GrantFiled: May 24, 1994Date of Patent: August 1, 1995Assignee: Sanyo Electric Co., Ltd.Inventors: Katsuaki Hayami, Hideo Fujii, Yoshihiro Wada, Yoshiharu Omori, Kuniyasu Kubo, Chizuko Konishi, Yoshitsugu Takada
