  • 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 securing part is a tubular section with a substantially closed mantle surface and receives a winding of the heat conductor coil.

    Abstract: The electrical gridiron that utilizes water is very small and portable, practical for household and easily maintained, and it could be utilized in an enclosed areas, with optimal temperature grilling and without creating smoke, while it does not allow overheating of food that can create substances harmful to health. Heating elements are placed laterally on the sides of the gridiron away from food juices that drain and could otherwise burn and create smoke which would be partially absorbed by the food being cooked, which is harmful for health. The heating elements radiate heat upwards, preventing excessive evaporation of water from the water container that would otherwise require frequent addition of water. The optimal temperature for grilling is maintained by raising the grilling bars to desirable heights by placing legs of the grilling bars in the provided slots, and if more ventilation is desired, by opening and adjusting a grating plate at the bottom of the gridiron.

  • Publication number: 20030010769
    Abstract: According to an embodiment of the invention, an electric radiant heater (11, 111) is provided having an active sensor (21, 121) for detecting the position of a cooking vessel on a glass ceramic plate over the radiant heater (11, 111). The sensor (21, 121) is made from electrically conductive material and is part of an inductive resonant circuit of a control operating by resonant circuit detuning. It also covers a heating zone (17, 117) of the radiant heater (11, 111). According to the invention, the sensor (21, 121) runs substantially linearly and, unlike conventional sensor coils, has a loopless construction. It is e.g. possible to stretch a wire (121) or also to use the tube (21) of a rod regulator.

  • Publication number: 20020170906
    Abstract: A radiant electric heater (2) comprises a dish-like support (6) having a base layer (8) of thermal insulation material. At least one heating element (10) is supported relative to the base layer. A temperature-responsive device (16) has a rod-like component (18) secured at one end at a peripheral region of the dish-like support (6) and extends without support partly across the heater over the at least one heating element (10). Restraining means (30) is provided at a free end region (28) of the rod-like component (18). The restraining means (30) has a first portion (32) thereof secured in the base layer (8) of thermal insulation material and a second portion (34) thereof at least partially surrounding and spaced from the rod-like component (18) to allow limited relative movement between the rod-like component and the second portion of the restraining means (30).

  • Patent number: 6483084
    Abstract: According to an exemplary embodiment of the invention a radiant heater (11) for a glass ceramic cooking area (25) is created. The radiant heater comprises a carrier shell (12) carrying a flat insulator (14), on which is placed a heating means (16). A thermal relay (18) projects with its tube-like sensor (19) into the central area of the radiant heater (11) and the sensor can rest on an elevation (23) of the insulator (14). By means of a holder (45) the sensor (19) can be fixed to the carrier shell (12). The holder does not project over the underside of the carrier shell (12). In one embodiment the holder with barb-like ends reaches into an opening in the carrier shell and is fixed to locking edges of the carrier shell.
