  • Patent number: 7174885
    Abstract: A cooking apparatus capable of uniformly heating and cooking food laid on a grill unit using thermal energy radiated from a heating unit, includes a cabinet opened at a top surface thereof to provide an opening over which the food to be cooked is laid. A grill unit is seated in the opening of the cabinet so as to support the food over the opening. A heating unit is installed in the cabinet at a position offset from an effective grill part of the grill unit so that a front surface of the heating unit faces the grill unit to transmit thermal energy to the grill unit supporting the food laid thereon. The cooking apparatus also includes a heat blocking member to block a part of the thermal energy transmitted to an edge of the grill unit, thus allowing the thermal energy to be uniformly transmitted to the food laid on the grill unit. Thus, the cooking apparatus of the present invention allows food laid close to the edge and food laid on a central portion of the grill unit to be uniformly heated and cooked.
