  • Patent number: 11866982
    Abstract: A cooker with a door includes: a proximity sensor configured to detect presence or absence of an object in proximity to the cooker; and a door opening controller configured to control the door to open and close on a detection signal from the proximity sensor, wherein the door opening controller opens the door when receiving the detection signal from the proximity sensor twice or more within a predetermined time period, the detection signal indicating the presence of the object.

  • Patent number: 11659635
    Abstract: A heating cooking apparatus includes a microwave supply unit, an image capturing unit, a communication unit, and a controller. The microwave supply unit supplies microwaves to an object to be heated and heats the object to be heated. The image capturing unit captures an image of the object to be heated. The communication unit transmits an image capturing result generated by the image capturing unit to a server. The controller controls the microwave supply unit such that an intensity of microwaves is reduced to be less than an intensity of microwaves before the communication unit transmits the image capturing result while the communication unit transmits the image capturing result to the server. After the communication unit transmits the image capturing result, the controller controls the microwave supply unit such that at least one of an intensity of microwaves or a supply time period of the microwaves is increased.

  • Patent number: 4857686
    Abstract: In a circuit for detecting the heating chamber temperature in a microwave oven, a switching transistor is connected in series or parallel with a heating chamber temperature detecting thermistor. If and when the heating chamber temperature need not be detected, the switching transistor is turned on when the switching transistor and thermistor are connected in parallel and off when the switching transistor and thermistor are connected in series to consequently prevent corrosion of the terminals of such thermistor.
