Patent number: 8884197Abstract: An indoor or outdoor induction cook top with a heat management system is disclosed. The cook top controls heat generated by various components, including the electronic controller, mechanical controls, and the induction generators. The heat management system provides precise temperature control and an efficient way of removing heat from the cooktop. The cook top construction provides the ability to incorporate a smooth ceramic glass cook top and a number of induction hobs in multiple arrangements. The cook top also features a reduction in the number of components, the efficient removal of generated heat, the reduction of noise, an increase in performance and a barrier airflow director. Consequently, the cook top may be installed in a countertop without the need for venting above the counter.Type: GrantFiled: February 4, 2008Date of Patent: November 11, 2014Assignee: Western Industries, Inc.Inventors: John M. Gagas, Scott A. Jonovic, Richard C. Hochschild, Jr.

Patent number: 8872077Abstract: An induction cook top may include a heat management system. The heat management system controls heat produced both internally by the electronic components within the cook top as well as heat produced above the cook top when cooking. The heat management system provides improved air flow past and around the internal electronic components. The cook top features an efficient removal of generated heat and may optionally provide a vented housing and direct airflow into and out of the housing or provide a thermoelectric cooling device which permits a ventless housing.Type: GrantFiled: December 23, 2009Date of Patent: October 28, 2014Assignee: Western Industries, Inc.Inventors: John M. Gagas, Scott A. Jonovic, Richard C. Hochschild, Jr.

Patent number: 8853599Abstract: An induction heating cooking apparatus includes a magnetic flux-shielding plate 28 to restrain magnetic flux leakage from a heating coil 24 and define a cooling air trunk 33, through which cooling air from a fan 32 passes. An infrared sensor 26 for detecting infrared rays emitted from a cooking container 22 and a control circuit 27 for controlling an output of a heating coil 24 depending on an output from the infrared sensor 26 are accommodated within the same space with respect to the magnetic flux-shielding plate 28 to thereby enhance assemblage. Also, the infrared sensor 26 is mainly cooled by cooling air passing through a cooling air trunk 33 to thereby enhance the cooling efficiency of the infrared sensor 26 and conduct correct temperature detection.Type: GrantFiled: May 26, 2009Date of Patent: October 7, 2014Assignee: Panasonic CorporationInventors: Takaaki Kusaka, Akira Kataoka, Kazunori Takechi

Patent number: 8791399Abstract: An object of the invention is to accurately detect a state of an object to be heated in a cooking vessel and effectively avoid cooking failure. An induction heating section (13) inductively heats a cooking vessel (11). A vibration detecting section (14) detects a vibration of the cooking vessel (11) via a top plate (12). A vibration waveform extracting section (15) extracts a vibration waveform of a frequency component having a frequency equal to a predetermined multiplication product of an induction heating frequency, from a waveform of the vibration detected by the vibration detecting section (14). A determining section (16) determines a state of an object to be heated, based on the vibration waveform extracted by the vibration waveform extracting section (15).Type: GrantFiled: May 1, 2007Date of Patent: July 29, 2014Assignee: Panasonic CorporationInventors: Sachio Nagamitsu, Makiko Noda

Patent number: 8772684Abstract: Operability of a heating cooker having a heating unit in a top plate is improved. After power-on, a light emission control unit causes the operation unit light-emitting element of an operable operation inhibition releasing key to be lit so that only the key is displayed and the other keys are less visible. Thus, the heating cooker is changed into a lock state. When the operation inhibition releasing key is operated in the lock state, at least one electrostatic touch key other than the operation inhibition releasing key is made operable and the operation unit light-emitting element is lit. Alternatively, in the above structure, the operation unit light-emitting element of the operable operation unit is lit in a first light-emission color, and the operation unit light-emitting elements of the inoperable operation units are lit in a second light-emission color different from the first light-emission color. Thus effective operation can be guided.Type: GrantFiled: November 12, 2007Date of Patent: July 8, 2014Assignee: Panasonic CorporationInventors: Keiko Isoda, Ryuuji Nagata, Chikashi Satou, Tsuyoshi Inada
