  • Patent number: 6998582
    Abstract: An open-air cooking apparatus for cooking pizza and the like, includes a horizontal, rotatable, circular turntable cooking surface, sized to support and cook several items simultaneously. The turntable should preferably structured to provide constant, even heat throughout its surface. As the oven is open-air, the cooking of the items will be primarily conduction of heat from the surface of the turntable through the bottom of the item. As the items rotate, they will pass under a static radiant heat source located above the turntable. The radiant heat source will thus direct heat towards the top of the item only periodically, i.e. at one point per rotation. This allows the item, such as a pizza, to cook thoroughly from below by way of the cooking surface, while cooking and/or browning the top portion at a different, desired degree.

The electric heating plate is electrically connected to the cabinet, and is removable from the cabinet. The present invention also provides a cooking apparatus, which allows food to be rapidly heated and cooked using a heat source installed in an electric heating plate, thus shortening cooking time and reducing power consumption. The present invention is also designed such that the electric heating plate is removable from a cabinet, thus allowing the electric heating plate to be conveniently cleaned.

  • Publication number: 20040112886
    Abstract: The invention relates to a ceramic cooktop comprising a cooking plate (12) made of glass ceramic or glass. The ceramic cooktop also comprises an electrical heat conductor layer (22) and an insulating layer (14) that is located between the cooking plate (12) and the heat conductor layer (22). The insulating layer (14) consists of a plurality of individual layers (16, 18, 20) that each have a porosity that decreases toward the heat conductor layer (22).

  • Patent number: 6734402
    Abstract: A cooking device includes two casings each having an inner portion, and a shelf disposed in the middle portion. A heating device is disposed and supported on the inner portions of the casings, and may either be the electrical heating members, or gas stoves, or furnaces, etc. The casings and the heating device may be assembled by the users when required, and may be disengaged from each other for allowing the cooking device to be easily stored and packaged. The casings each may include a chamber to receive boiled fluid material.

  • Patent number: 6387185
    Abstract: A processing station adaptable to standard cluster tools has a vertically-translatable pedestal having an upper wafer-support surface including a heater plate adapted to be plugged into a unique feedthrough in the pedestal. At a lower position for the pedestal wafers may be transferred to and from the processing station, and at an upper position for the pedestal the pedestal forms an annular pumping passage with a lower circular opening in a processing chamber. A removable, replaceable ring at the lower opening of the processing chamber allows process pumping speed to be tailored for different processes by replacing the ring. In some embodiments the pedestal also has a surrounding shroud defining an annular pumping passage around the pedestal. A unique two-zone heater plate is adapted to the top of the pedestal, and connects to a unique feedthrough allowing heater plates to be quickly and simply replaced.

  • Patent number: 6347535
    Abstract: When an object to be heated is heated without temperature nonuniformity in its heated surface, unwanted thermal deformation can be suppressed, and thermal processing precision can be improved. For this purpose, a heat transfer plate for heating a plate-like object to be heated, and a base plate are stacked. A rod heater as a heat source is inserted in the heat transfer plate. The heat transfer plate has a larger thermal conductivity and smaller creep than the base plate.
