Patent number: 9565721Abstract: An infrared sensor for detecting infrared rays of light and a light emitting element are disposed below a light transmittable top plate, which has a hearing area for heating an article to be heated placed thereon, in juxtaposed fashion relative to each other, so that infrared rays of light radiated from the article to be heated may be guided towards the infrared sensor. A light guide portion is provided for guiding rays of flight, emitted from the light emitting element, towards a heating area of the top plate, and the rays of light emitted from the light emitting element and guided by the light guide portion are projected onto the top plate through an upper opening of the light guide portion so that such rays of light can be noticed with eyes within the heating area.Type: GrantFiled: December 18, 2007Date of Patent: February 7, 2017Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Kazuichi Okada, Masahiro Yokono

Patent number: 8003925Abstract: Waste heat of a high temperature inside a main body is designed to be discharged to the outside of the main body by means of a discharge fan through a first suction air flow passage and a first discharge air flow passage. Also, through a second air flow passage communicating from a second discharge fan suction port to a discharge fan suction portion, air from the outside of the main body or air at a site of the main body, where the temperature is low, is sucked by a discharge fan so that the air of a low temperature can pass outside the drive motor to cool the latter. With this construction, the interior of the main body and the drive motor can be cooled efficiently.Type: GrantFiled: August 23, 2006Date of Patent: August 23, 2011Assignee: Panasonic CorporationInventor: Kazuichi Okada

Patent number: 7533666Abstract: A built-in heating cooker which features both good cooling performance and effective countermeasures against spilled liquids by preventing ingress of water into the cooker body with a simple ventilation structure. This built-in cooker comprises a top plate where a pot and the like are placed, a support for supporting the top plate from underneath, a top frame covering the edge of the top plate and a frame constituting the cooker body. The support has a cooker-supporting face for supporting the cooker, and this is positioned outside of the top plate-supporting face. A first opening is provided on at least one side wall provided between the top plate-supporting face and the cooker-supporting face. A second opening is provided on a frame in a position corresponding to the first opening.Type: GrantFiled: October 20, 2004Date of Patent: May 19, 2009Assignee: Panasonic CorporationInventors: Koichi Hosoi, Kazuichi Okada, Satoru Kodama

Patent number: 4899028Abstract: According to the electromagnetic cooking apparatus of the present invention, a ventilation hole, through which air after cooling an interior compartment of the main casing of the cooking apparatus is exhausted, communicates with the exhaust passage of the exhaust device so that the suction force of a fan member of the exhaust device is also utilized for exhausting the cooling air, thereby contributing to an improvement in the exhausting efficiency of the cooking apparatus, and the fact that a relatively small fan motor for the cooling device can be used. Consequently the cooling device can be small, which in turn enables the size of the electromagnetic cooking apparatus itself to be relatively small.Type: GrantFiled: February 24, 1989Date of Patent: February 6, 1990Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Akihiko Arai, Kazuichi Okada, Tetsuo Kamo, Eiji Shiota

Patent number: 4665893Abstract: A cooking stove such as an induction heating cooking stove which is fitted into an aperture on top of a kitchen unit has one or more independent heater units mounted within an outer case, below a top plate which cooking pans, etc can be heated. Each heater unit consists of an open-ended box-shaped internal chassis having one or more heater elements mounted on a top face thereof and an aperture formed in a bottom face thereof. Each internal chassis is provided with a motor-driven cooling fan which acts to produce a flow of cooling air through the interior of the chassis and out through the lower aperture into a ventilation duct, and hence to the atmosphere via a cooling air inlet/outlet section which can be conveniently provided at the upper rear part of the top of the stove. No additional ventilation apertures need be provided in the kitchen unit, and the number of heater elements can be readily varied as required, while the overall design is extremely simple and readily manufactured.Type: GrantFiled: October 28, 1985Date of Patent: May 19, 1987Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Junichi Miyagawa, Tetuo Kamo, Kazuichi Okada
