  • Patent number: 7094998
    Abstract: A heating cooker which evenly heats or cooks food, and is easily cleaned, includes a cabinet to define a cooking cavity therein. The cooking cavity is open at a front thereof. A fan chamber is defined by recessing a rear wall of the cooking cavity at a predetermined area to a predetermined depth. An air circulation fan and a heater are installed in the fan chamber. The air circulation fan circulates air of the cooking cavity. The heater heats the air in the fan chamber. A chamber cover is mounted to the rear wall of the cooking cavity to cover an open front of the fan chamber. The chamber cover has a plurality of air suction ports at a central area thereof, with a plurality of air distribution ports provided along an edge of the chamber cover to guide the air from the fan chamber to the edge of the chamber cover so as to discharge the air to the cooking cavity.

  • Patent number: 6891133
    Abstract: A cooking apparatus to improve heating efficiency and to quickly cook food. The cooking apparatus includes a heater provided at a tray receiving food to be cooked and having a pair of terminals to supply power to the heater, and a plurality of sockets provided at a rear wall of a cooking cavity. When the tray is placed on a pair of support rails of the cooking cavity and the terminals of the heater are inserted into one of the sockets, the tray is directly heated by the heater to cook the food. The heater includes a conductive film coated on a lower surface of the tray, and first and second electrodes connected to the conductive film to be opposed to each other and connected to the terminals. The conductive film and the tray are heated by current flowing through the conductive film between the first and second electrodes.
