  • Patent number: 7135662
    Abstract: A method and apparatus for controlling the operation of a microwave oven, including a magnetron generating microwaves and a sensor sensing the state of air in the cooking cavity of the oven. The cooking period is determined by searching one of two data tables in accordance with a determination result after determining whether food to be cooked is included in ascending slope-type foods or descending slope-type foods. The control method and apparatus remarkably reduces a deviation in the cooking periods by distinguishing the ascending slope-type foods from the descending slope-type foods. The control method and apparatus allows the microwave oven to appropriately cook food for a period of time which substantially matches a practically required cooking period, thus providing a good cooking result.

  • Patent number: 7001626
    Abstract: An automated grill automatically transfers frozen food from a freezer component to grilling component by an automatic loading device in response to a signal. Frozen food is loaded in a loading side in the freezer component. When the signal is received indicating that the food is to be grilled, food in a feeding side is raised and delivered to the loading device. When a sensor detects that food is positioned in the loading device, the loading device removes the food from the freezer component and into the grilling component. The food is then grilled as it travels between two substantially vertical grilling structures each surrounded by a conveyor belt. Preferably, the conveyor belt is made of a non-stick coated Invar. A lateral sensor detects and compensates for lateral movement of the conveyor belts. After the food exits the grilling component, the food slides onto a heated holding area for serving.

  • Patent number: 6862494
    Abstract: An automated cooking system (10) cooks food (12) accompanied by machine-readable indicia, such as a bar code (16) read by a reader (18). Cooking data, including function coefficients, are accessed from an Internet server (20) based on the information in the bar code. An oven (40) cooks the food in phases in response to the cooking data and one or more monitored food parameters of humidity, temperature and weight. The cooking is controlled by functions in which one or more food parameters are multiplied by coefficients that vary according to food type.

  • Patent number: 6812440
    Abstract: An induction heating device prevents an object to be heated from being displaced and buoyed from a mounting surface due to an mutual action of repulsive forces between the object to be heated and an induction heating coil. The induction heating device includes a source-current detector for detecting a source current input to a high-frequency inverter including the induction heating coil and an inverter circuit, a source-current change detector for measuring a change against time of a magnitude of the source current to detect a displacement and buoying of the object to be heated, such as a cooking pot, and a change examining unit. The controller controls an output of the high-frequency inverter in response to a detection result of the change examining unit. The induction heating device prevents the cooking pot from being displaced and buoyed even if the pot is not touched by a user at startup of heating or during the heating operation, and is inexpensive and safe.

  • Patent number: 6809301
    Abstract: A control system for a an oven having at least one cooking element and a surface warmer includes a microprocessor, a memory, and a user input interface for user entry of cooking recipes including a cooking mode, an oven temperature, and a cooking time. Up to five favorite recipes can be stored in system memory for selection by a user, and two recipes can be combined for automatic sequential execution. The surface warmer is operable upon manipulation of two input selectors within a pre-determined time, and a preheat algorithm preheats the surface warmer by applying a 100% duty cycle to the surface warmer until an oven thermal limiter input switch reaches a predetermined temperature.

  • Patent number: 6791070
    Abstract: A method of performing a simmer cooking operation in a microwave oven is based on detected levels of humidity from a sensor and an algorithm automatically calculating a cooking time such that a desired cooking operation is optimally performed. A third heating operation is performed at about 30% of the maximum power level of the microwave oven. The third heating operation is performed for an amount of time equal to a sum of an amount of time during which first and second heating operations are performed adjusted by a predetermined constant. The total heating time is calculated and controlled by adding the amount of time during which the third heating operation is performed to the time during which the first and second heating operations are performed.

  • Patent number: 6744026
    Abstract: Cooking information (CI) concerning different dishes is preliminarily registered as a standard in a mask ROM (11A) or the like of a microwave oven (1), to enable automatic cooking of a variety of dishes for every user. In practice, however, the dishes which each user cooks by a microwave oven is limited to a few of them. Then, the user selects and registers a standard recipe name (HN) of only his/her favorite dish in the mask ROM into a favorite menu in a non-volatile memory (11B). In order to execute cooking of a desired dish registered in the favorite menu, the standard recipe name of the desired dish is read not from the mask ROM but from the non-volatile memory and displayed on an LCD panel (13), so that the user needs only perform an operation to instruct start of heating through an input unit (15).

  • Patent number: 6730882
    Abstract: A cooking appliance, such as a range, includes a cabinet within which is arranged an oven cavity that is adapted to be selectively closed by a pivotable door. A latching mechanism is provided to interconnect the door and the cabinet. The latching mechanism is movable between a locked position wherein the door is maintained closed and an unlocked position wherein the door can be pivoted to enable access to the oven cavity. The latching mechanism is operable in two distinct modes, i.e., a first mode wherein the latching mechanism is activated in conjunction with the operation of a self-clean cycle, and a second mode wherein the latching mechanism is operated independently of any other function of the cooking appliance. The second mode is particularly employed to prevent children from improperly utilizing the door as a stepping platform.
