Patent number: 7315012Abstract: To provide a microwave baking furnace in which an inner wall which constitutes a heating element partitioning a baking chamber is prevented from being damaged due to a thermal shock, and the life time thereof can be extended. A microwave baking furnace 31 includes a partition wall 35 of a heating element 33 which partitions a baking chamber and which has an inner wall 35b made of a material self-heating by microwave radiation and transmitting part of microwaves radiated thereto, and an outer wall 35a made of an insulating material permitting the microwaves to be transmitted therethrough and covering an outer circumference of the inner wall 35b. A clearance 39, which serves as a convection path of heat inside the baking chamber 23, is secured between the inner wall 35a and the outer wall 35a. The inner wall 35b is attached to the outer wall 35a such that it can move relative to the outer wall 35a by a predetermined distance in all directions.Type: GrantFiled: April 7, 2005Date of Patent: January 1, 2008Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yoshihiro Hisamatsu, Eiji Nomura, Kazuhiko Tachikawa

Patent number: 7297909Abstract: Microwave radiation of frequency 0.1 to 20 GHz, is applied to the melt of viscosity in the range 104 to 101 Pa·s. The outside surface of heated space, where an outlet of the waveguide of microwave radiation is located, can be cooled. The microwave radiation in the melt may be reflected by the reflective metallic elements in the melt back to the place of radiation entry into the melt and shielded from the surroundings by a shielding metallic element. An outlet is provided of at least one waveguide from the source of the microwave radiation, in any direction to the outside surface of the melt, into the space with the melt of a given viscosity. At least one waveguide is led, for example, to the outside surface of the bottom of the channel of the forehearth.Type: GrantFiled: November 15, 2002Date of Patent: November 20, 2007Assignee: BH-F (Engineering) Ltd.Inventors: Josef Smr{hacek over (c)}ek, Milan Hájek, Peter Vilk

Patent number: 7282683Abstract: The present invention provides a high frequency heating apparatus having a structure, which can be mounted/dismounted an air-exhausting grille without any tools. In this apparatus, an air-exhausting grille is arranged by that a fixing claw portion having a bent Z-shape, a fixing hooking portion having a concave notch, and a magnetic joint plate are arranged, whereas a main body located opposite to the air-exhausting grille is arranged by that a slit hole, a hooking flange, and a magnetic fixing plate are arranged. As a result, since the magnetic joint plate is absorbed with the magnetic fixing plate to be fixed with each other, the mounting/dismounting work capability of the air-exhausting grille can be improved without using the tool in a simple manner, and furthermore, a clean cooking appliance can be secured, while the cooking appliance can be readily cleaned.Type: GrantFiled: April 14, 2005Date of Patent: October 16, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Masato Yamauchi, Toshiyuki Ishiguro, Hirofumi Yoshimura, Fumihiko Migaki

Patent number: 7244916Abstract: A heating and cooking apparatus includes a cooking apparatus main body having a heating chamber, a drawer body including a base for carrying a heated target and formed such that the base moves from inside of the heating chamber to outside, a door drive motor moving the drawer body, and a control unit controlling the door drive motor for varying a moving speed of the door. The control unit is formed to control the door drive motor such that a moving speed of the drawer body at at least one stage selected from a group consisting of a draw-out initial stage, a draw-out final stage, a push-in initial stage, and a push-in final stage is relatively slower than a moving speed of the drawer body in an intermediate stage of a draw-out and push-in operation.Type: GrantFiled: January 4, 2005Date of Patent: July 17, 2007Assignee: Sharp Kabushiki KaishaInventor: Masayuki Iwamoto

Patent number: 7232979Abstract: A microwave oven liner 11 is an injection moulding having a roof 12, a floor 14, a back 15 and two sides 16. The moulding is of food grade polypropylene, such that the liner can be washed in a commercial dishwasher. The liner is sized to be a sliding fit in a microwave oven. The roof is shorter 17 at the front than the floor to allow air circulation. Further, the roof is apertured, also for air circulation, with a series of small c. 4 mm bores 18 registering with the roof aperture 8. A lip 19 is provided across the front of the floor to retain split liquid. The external corners 20 are chamfered to clear the silicone seal 9 for instance. The floor has regularly pitched, 2 mm high ridges 21 running front to back. The ridges allow circulation of air beneath a container of food being heated in the oven having the liner.Type: GrantFiled: August 4, 2003Date of Patent: June 19, 2007Assignee: Cavity Protection Systems Ltd.Inventor: Patrick Leon Bray
