Patent number: 8519310Abstract: A cooking appliance. The cooking appliance includes a cook top for a kitchen. One side of the cook top includes a cooking area with cooking areas. The cooking areas may be operated via an induction cooker. The bottom side of the cooking appliance has a display. The display can provide useful information thereon such as the time. The cook top can be arranged in a first horizontal position for use of the cooking areas, and folded to a second vertical position during non use to display information on the display. The cooking appliance also includes a data reader, such as an RFID reader or bar code scanner to obtain data from a food product package. The data may include suggested recipes, cooking temperatures, and/or cooking times. The obtained data may be used to assist in controlling the operation of the cooking areas.Type: GrantFiled: December 24, 2010Date of Patent: August 27, 2013Assignee: Aktiebolaget ElectroluxInventor: Matthias Pinkert

Patent number: 8492684Abstract: A method for detecting the presence of a cooking vessel on an induction heating element is disclosed. The induction element is placed below a glass surface and a conductive electrode placed below the glass surface to detect if a cooking utensil is placed on the induction heating element. The electrode measures capacitance, which indicates to the user whether the cooking utensil is present on one or more induction heating elements. After activation by a user, a second detection of the cooking utensil is accomplished by feeding power to the induction heating element and by assessing at least an electrical parameter of a power circuit thereof.Type: GrantFiled: October 20, 2009Date of Patent: July 23, 2013Assignee: Whirlpool CorporationInventors: Diego Neftali Gutierrez, Ettore Arione

Patent number: 8450665Abstract: An induction heating device according to the present invention includes an infrared ray sensor for detecting infrared rays radiated from a cooking container through a top plate, a light emitting device which is placed near the infrared ray sensor and emits light to the back surface of the top plate, and a heating control unit which controls a high-frequency current through a heating coil for controlling the heating of the cooking container. When the heating control unit has stopped the heating of the cooking container, and a predetermined time elapses at the heating-stopped state, the light emitting device is controlled to stop the light emission therefrom. This can improve durability of the light emitting device, which enables maintaining a function of clearly indicating a position at which the cooking container should be placed and a function of detecting failures in the infrared ray sensor, which are roles of the light emitting device.Type: GrantFiled: June 23, 2008Date of Patent: May 28, 2013Assignee: Panasonic CorporationInventors: Fumitaka Ogasawara, Keiko Isoda, Hiroshi Tominaga, Masamichi Komada

Patent number: 8426782Abstract: An induction heating device has an accurate sensing of the temperature of a to-be-heated object and is user-friendly. The induction heating device includes a sensor for sensing the temperature of the to-be-heated object and can carry out a heating operation only when it is determined that the to-be-heated object exists above the sensor. A display having a circular design and characters, for example, that shows the position of this sensor is provided on a top plate of the induction heating device.Type: GrantFiled: November 8, 2006Date of Patent: April 23, 2013Assignee: Panasonic CorporationInventors: Toshihiro Keishima, Akira Kataoka, Hirofumi Nakakura, Izuo Hirota
