    Abstract: 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.

  • Patent number: 7105779
    Abstract: In general, one embodiment of the invention is directed to food holding apparatus for holding pre-cooked food at a selected holding temperature. The apparatus comprises a cabinet having at least one holding compartment therein, and pre-cooked food in the holding compartment, the food having been previously cooked in a cooking appliance. At least one radiant heat source is spaced above the food a distance less than 12 inches for delivering radiant heat to the food. A control mechanism varies the amount of radiant heat delivered by the heat source to the food to maintain the food at the selected holding temperature. A related method is also disclosed.

  • Patent number: 7102105
    Abstract: An electric oven including lower heaters arranged under a cooking chamber thereof. The electric oven includes an outer case defining the appearance of the electric oven, an inner case inwardly spaced apart from the outer case by a predetermined distance, and lower heaters arranged between bottom walls of the outer and inner cases. The inner case internally defines a cooking chamber, and a blowing fan is installed near the lower heaters to circulate air existing in the cooking chamber toward the lower heaters. With the electric oven configured as stated above, heat generated by the lower heaters is transferred to the cooking chamber in the form of conductive heat and convective heat, resulting in fast and efficient heat transfer and even cooking of food.

  • Patent number: 7087867
    Abstract: The oven includes a lower electrical heating element which is located below a support member. Two laterally spaced apart upper electrical heating elements are supported above the support member and the food to be cooked. An electrical system is provided for supplying electrical power to the lower electrical heating element and to the two upper electrical heating elements. A controller is provided for controlling electrical power applied to the lower heating element and to the two upper electrical heating elements. By way of a thermocouple, the controller senses the temperature in the oven and controls the lower heating element to maintain a set point temperature, i.e. 550° F., in the oven. When any of the upper heating elements is activated, and is in a broiling sequence the controller disables these upper heating elements if the temperature in the oven rises above an upper temperature level of i.e. 585° F.

  • Patent number: 7087864
    Abstract: A cooking device is provided which blows most of the air blown from a circulation fan in a heater room to a heater, such that the heating of air by the heater is facilitated and the volume of the rear side of a heater case is reduced to permit manufacture of the cooking device in a small size. The cooking device includes a heater case provided to form a heater room in an inner case, a circulation fan installed in the heater room, a heater installed outside of the circulation fan in the heater room, a motor mounted outside the heater case and driving the circulation fan, and a first sunken part formed such that a portion of the heater case, on which the motor is mounted, is sunken inward with respect to the heater room by a predetermined depth.

  • Patent number: 7069109
    Abstract: Multiple microcontrollers are used in controlling operation of an appliance thereby providing enhanced safety. User input deactivating the appliance is received and processed by a first and second microcontrollers, which separately and independently act to remove power from the appliance upon receipt of user input. Failure of one microcontroller in processing user input does not result in the appliance entering into an unsafe mode. Further, a third processor in a power supply module is used to control power into, and out of, the power supply module, so that under certain conditions, power may be remove from the system entirely or to certain components.

  • Patent number: 7009147
    Abstract: A cooking appliance includes a controller for establishing a plurality of operating modes for heating an oven cavity. Specifically, the controller establishes one of a pre-heat mode, a ready mode, a first low power mode and a second low power mode for controlling a temperature of the oven cavity. Upon selecting a temperature for the oven cavity, the controller operates a radiant heating device, a convection fan and a convection heating device at full power to establish the selected temperature. After the selected temperature is achieved, the controller switches to a ready mode and reduces heat output of both the radiant heating device and the convection heating device, while also reducing fan speed. After respective periods of time in which a door of the appliance is not opened, the controller switches to first and second low power modes to conserve energy.
