Patent number: 7282677Abstract: A menu selection device for a cooking device is provided which is constructed such that a single display device may be divided into a menu guide unit and a menu selection unit. The menu guide unit is used to display a variety of menus, whereas the menu selection unit is constructed in the form of a touch screen which allows for selection of a particular menu from among the menus displayed on the menu guide unit. Use of a menu guide unit and a menu selection unit within a single display device makes a greater variety of cooking alternatives available to a user, while decreasing the size of the touch screen portion of the menu selection device and decreasing production costs.Type: GrantFiled: May 1, 2006Date of Patent: October 16, 2007Assignee: LG Electronics Inc.Inventor: Dae-Ho Kang

Patent number: 7241978Abstract: The present invention provides a cooking heater which continues cooking without apparently stopping the operation of the cooking heater when a door switch is momentarily turned OFF due to a shock during operation of the cooking heater though the door is not actually opened as far as continuation of the OFF-state is within a predetermined range. Upon receiving a door opening signal, a timer of control means starts counting and when a first period lapse judgment section judges that the count time exceeds a first period T1, a central control section instructs a heating means control section to stop the operation of heating means. Then, before the count time is judged to exceed a second period T2, when a second period lapse judgment section receives a door closing signal, the central control section restarts the operation of the heating means and continues the operation of the cooking heater.Type: GrantFiled: May 2, 2006Date of Patent: July 10, 2007Assignee: Sharp Kabushiki KaishaInventor: Masayuki Iwamoto

Patent number: 7227102Abstract: An oven for transferring heat to food in trays and a method for using the oven. The oven includes a cabinet with partitions dividing the interior into a plurality of separate, thermally isolated holding compartments each adapted for removably receiving a tray of food. Heat sources above the tray emit radiant heat to warm the food in the trays. A control mechanism controls the duration of the total hold time for the food having a duration of heated holding time during which a respective heat source is activated. The oven also includes a forced air mechanism under the control of the control mechanism for delivering forced air into the compartments. The heat sources are activated and deactivated during successive duty cycles to thereby to maintain the food in a respective compartment at a selected holding temperature for a duration of heated holding time.Type: GrantFiled: July 1, 2003Date of Patent: June 5, 2007Assignee: Duke Manufacturing CompanyInventor: Steven M.
