  • Patent number: 8610035
    Abstract: The invention provides a drawer type cooking device having a cooling fan 56a disposed laterally, so that a space 70 is formed below the cooling fan 56a, enabling a high pressure transformer 55 to be disposed efficiently using this space 70. By the combination of the arrangement, position and orientation of the cooling fan, it becomes possible to reduce the set depth size at the farthest portion of the cooking device body 1. By reducing the depth size, the front surface of a cabinet and the front surface of a door 2 can be disposed flush with each other, without having to sacrifice the depth of the heating chamber 6.

  • Patent number: 8357886
    Abstract: A drawer type cooking device for disconnecting and connecting the linkage between the drawer body and the movement mechanism in response to the user's selection of operation between a manual opening/closing operation and an electric automatic opening/closing operation of the drawer body. Based on the user's input via the operation unit, connection/disconnection of power transmission via a clutch mechanism and driving/stopping of a drive mechanism is automatically controlled. By turning the clutch mechanism off and isolating the drawer body from the motor, the load of manual operation to open/close the drawer body is reduced. Based on the user's operation via the operation unit, the clutch mechanism is set to connected state, and in that state, the drive mechanism is driven so that power is transmitted to the rack of the drawer body, and the drawer body can be automatically opened and closed.

  • Patent number: 7994457
    Abstract: A cooking device with a heating chamber therein. A drawer with a body portion having a heating container and a door that closes the heating chamber when the heating container is inserted into the heating chamber. A moving mechanism operable to engage the door in a manner to support the drawer while moving it from a closed position in which the door closes the heating chamber with the heating container inserted into the heating chamber to an open position with the heating container outside of the open heating chamber to permit objects to be placed in and removed from the exposed heating container. In order to facilitate easy access to the heating container when the drawer is in the open position, the moving mechanism is positioned below the heating container.
