Load Condition Sensor Patents (Class 219/704)
  • Patent number: 5362946
    Abstract: A cooking appliance has several sensors to detect which attachment has been placed in a cooking compartment. When a door to the compartment is closed and a start switch is operated within ten seconds, the appliance automatically starts cooking in a mode determined by the attachment detected by the sensors. After the door has been closed for ten seconds, even though the start switch is operated by accident, the appliance will not start cooking.

  • Patent number: 5283410
    Abstract: Method and apparatus for automatic cooking in a microwave oven capable of an automatic cooking operation even in case of consecutive cooking by discriminating whether the operation mode is an initial operation mode or a consecutive operation mode by receiving an inflow air temperature and an outflow air temperature in the initial operating stage, selecting the initial operation mode or the consecutive operation mode, executing a cooking operation by driving a magnetron and a cooling fan after calculating an arbitrary initial heating time, calculating a difference between the current outflow air temperature and the previous outflow air temperature when the initial heating time has been elapsed, giving a fuzzy membership function and rule for the selected initial operation mode or the consecutive operation mode by the outflow air temperature difference and a weight conversion value, calculating a cooking time by executing a fuzzy operation, calculating an additional heating time by subtracting the initial heati
