  • Patent number: 8291816
    Abstract: The invention provides a drawer type cooking device having an operation unit disposed on an upper portion of a drawer body so as to increase the height of the drawer body within a cooking device body as much as possible, capable of facilitating power supply and signal transmission between the control unit within the cooking device body and the operation unit when the drawer body is opened and closed. Slide mechanisms 4 disposed on left, right and bottom portions enabling the drawer body 2 to be moved into and out of the cooking device body 1 are composed of conductive materials, so as to provide a slidable state with constant conduction. By transmitting data via serial communication and supplying power to the operation unit from the cooking device body 1 to the drawer body 2, it becomes possible to dispose the operation unit on a door 2a being opened and closed.

  • Patent number: 8110779
    Abstract: There is provided a door lock control device in a heating cooker that prevents a door from being accidentally unlocked when the door is locked and a temperature inside the heating cooker is a predetermined temperature or more such as during self-cleaning. When the temperature inside the cooker is low and a thermal switch 8 of a lock detection and thermal switch portion 6 is closed, the lock detection and thermal switch portion 6 can be energized, and a power supply line 2 can supply power to a drive motor 5 to lock and unlock the door. In the case of self-cleaning or the like, the door is locked and a detection switch 7 is on a door lock side 7a, but the temperature inside the cooker is high and thus the thermal switch 8 is opened, and the power supply line 2 is interrupted.

  • Publication number: 20090139286
    Abstract: There is provided a door lock control device in a heating cooker that prevents a door from being accidentally unlocked when the door is locked and a temperature inside the heating cooker is a predetermined temperature or more such as during self-cleaning, and provides safe handling of the heating cooker. Even in general door lock and unlock states, when the temperature inside the cooker is low and a thermal switch 8 of a lock detection and thermal switch portion 6 is closed, the lock detection and thermal switch portion 6 can be energized, and a power supply line 2 can supply power to a drive motor 5 to lock and unlock the door. In the case of self-cleaning or the like, the door is locked and a detection switch 7 is on a door lock side 7a, but the temperature inside the cooker is high and thus the thermal switch 8 is opened, and the power supply line 2 is interrupted. Even if a failure in a driving component occurs, the drive motor 5 is not energized, thereby preventing the door from being unlocked.
