Patent number: 7481153Abstract: A toaster for heating a food stuff to a selected shade, includes a housing having at least one wall, at least one heating chamber within the housing for receiving the food stuff to be heated and at least one heating element for heating the food stuff in the heating chamber. A window is provided in the wall and a control knob is provided for controlling the time period that the food stuff is heated. The control knob is rotatable between a first end position at which the food stuff is heated for a short time period to provide a light food stuff shade, a second end position at which the food stuff is heated for a long time period to provide a dark food stuff shade and a plurality of intermediary positions between the first and second end positions it which the food stuff is heated for a selected time period between the short and long time periods to provide a food stuff shade between light and dark.Type: GrantFiled: October 13, 2006Date of Patent: January 27, 2009Assignee: Hamilton Beach Brands, Inc.Inventors: John D. Barnes, Martin Patrick Brady

Publication number: 20090007798Abstract: After a preheating operation is performed to raise an inner temperature of a heating chamber to a target preheating temperature (first specified temperature) by a first steam superheater of a steam temperature-raising device, a cooking operation is performed to raise, by the first steam superheater of the temperature-raising device, a temperature of steam obtained by heating of water in a steam generator by heaters 42A, 42B of the steam generator and then supply the steam to the heating chamber. In this process, when inner temperature of the heating chamber detected by an inner temperature sensor 81 during the preheating operation has come to or beyond a steam generation start temperature (second specified temperature) which is lower than a target preheating temperature, a control unit 80 decides that a steam generation start condition has been satisfied, and heats water in the steam generator by the heaters of the steam generator.Type: ApplicationFiled: July 28, 2005Publication date: January 8, 2009Inventors: Kiyoshi Yamaguchi, Yuko Nakajima, Noriko Ohashi, Mari Terada

Publication number: 20080319588Abstract: Method and control arrangement for terminating an accidental switch on of a deep fryer apparatus when it is not filled with oil, the apparatus comprises a vessel having closed bottom and sides, and a horizontally formed electric heating element for direct contact with the oil within the vessel. At one or more points of the inner space of the vessel the temperature is measured, by which the accidental switch on state of the apparatus is detected and terminated at the same time in such a way that a derivative of the temperature measured at the one or more determined points is defined. The heating power is automatically cut off to terminate switched on state when the value of the derivative exceeds a predetermined threshold value.Type: ApplicationFiled: December 17, 2004Publication date: December 25, 2008Inventor: Laszlo Kovacs

Patent number: 7467584Abstract: The present invention generally provides a roasting machine, which can roast both the food that needs to be rotated upon roasting and the food that does not need to be rotated while roasting. The roasting machine is provided with a housing for supporting and protecting a roasting cab and roasting pipes, a roasting plate for baking and heating various food which does not need to be rotated, roasting pipes for baking and heating various food which needs to be rotated continuously so that they can be uniformly heated, and a drive unit used to drive the roasting pipes to rotate. The roasting machine can be used to bake two kinds of food. As the roasting plate is removable, food which does not need to be rotated can be roasted when the roasting plate is placed over the roasting pipes, and the roasting pipes can be used to heat food which needs to be rotated so as to be heated, such as sausages when the roasting plate is removed.Type: GrantFiled: April 19, 2007Date of Patent: December 23, 2008Assignee: Guangzhou Light Holdings LimitedInventor: Jian Li

Publication number: 20080308547Abstract: A method of controlling an electric kettle for “dry” burn prevention during heating process, including the steps of: providing a temperature sensor, a microprocessor, and a control circuit; detecting the water temperature; determining the temperature rate change and comparing the temperature rate change with the rate change threshold; and when the temperature rate change is larger than the preset rate change threshold, sending a control signal to the control circuit. The microprocessor determines the temperature rate change and the acceleration rate change that when the temperature rate change and acceleration rate change are larger than the corresponding thresholds respectively, the microprocessor sends the control signal to the control circuit to stop the heating process. Therefore, the present invention accurately determines the increasing temperature of the water and simultaneously cuts off the heating power to prevent the electric kettle from being burnt.Type: ApplicationFiled: September 10, 2005Publication date: December 18, 2008Inventors: Mohan Zhang, Yaolun Wang

Publication number: 20080282902Abstract: The invention relates to an apparatus used for automatically shutting off cooking appliances, such as ovens, stoves, hot pots, toasters, grills, and others. More specifically, the apparatus is secured to a cooking appliance, e.g. to its control panel, and may prevent a cooking appliance from being turned on before a timer is set. The apparatus can also increase the ease with which a cooking appliance knob or other actuator may be used. To automatically shutoff the cooking appliance, the apparatus uses a timing mechanism with a spring. Pressure is exerted on a spring when the timer is set, storing enough force in the spring to enable it to turn the cooking appliance to the OFF position when time has expired. A mechanical stop is in place to keep the spring energy from releasing until the timer reaches the OFF position.Type: ApplicationFiled: January 7, 2008Publication date: November 20, 2008Inventors: Douglas C. Dayton, Elizabeth Johansen, Angie Kim, Sung K. Park
