Abstract: Modern cooktops typically have a cook surface which is formed by a glass or glass-ceramic plate (1). As an alternative to the electrically heated cooking locations, cooking locations heated by a gas burner, called burner locations (2), can be provided. The heating location is heated by a gas burner. To avoid the use of complex exhaust-gas channels when using gas radiation burners and to further utilize the heat of the exhaust gas for heating the cooking utensil as well as for avoiding the use of separate pot supports when using atmospheric gas burners, the invention provides that the burner location (2) is formed by a mesa-like protrusion (3) in the glass or glass-ceramic plate (1), below which the gas burner (4, 4a) is arranged, with the mesa-like surface (3a) formed as a pot support surface and with a surrounding flank (3b) in which the openings (5, 6) are formed.

Abstract: The cooking apparatus includes a glass-ceramic panel (1), which has at least one cooking area; a gas burner (3) providing an open flame (3); a cooking vessel support (5) including feet (5b) and a resting surface for a cooking vessel (6) placed on the cooking vessel support (5); and a device for holding the cooking vessel support (5) mechanically fixed and centered over the gas burner (3) including a foot holding device for holding the cooking vessel support (5). The foot holding device includes foot holders (7) for the respective feet, which are preferably formed by depressed or raised regions in the glass-ceramic panel or foot holder parts attached to it. The cooking apparatus of the invention is easier to clean and more economical than prior art cooking apparatus.

Abstract: The cooking device includes a glass-ceramic molded body (2) providing a cooking surface. The glass-ceramic molded body (2) includes a closed or an open upwardly projecting portion (3,13) that, together with a glass-ceramic cover (11) that fits over it, forms a gas/air mixing chamber (5) of a gas burner. The glass-ceramic cover (11) together with either a concave upper surface of the molded body (2) surrounded by the closed upwardly projecting portion or together with a burner section inserted in the open upwardly projecting portion, bounds the mixing chamber (5).

Abstract: The cooking apparatus includes a glass or glass-ceramic plate (1) providing a cooking surface with a cooking area and provided with a throughgoing opening (2) in the cooking area; a gas burner (3, 19, 21) arranged in or under the throughgoing opening (2) in the glass or glass-ceramic plate (1), which has a burner ring (3b) for supporting an open flame (3a, 19a, 21a); a cooking vessel support (5,5a) arranged on the glass or glass-ceramic plate over the throughgoing opening (2) which has a resting surface for a cooking vessel (6) and a device for supplying a mixture of combustible gas and primary air to the burner ring (3b) to form the open flame, whereby substantially all of the secondary air is drawn from a chamber or space under the glass or glass-ceramic plate (1). Because the secondary air is drawn from below the glass or glass-ceramic plate the height of the resting surface of the cooking vessel support (5,5a) can be substantially reduced to less than 10 mm without impairing the combustion process.

Abstract: A cooking surface that is made of glass or glass ceramic and at least one atmospheric gas burner and arrangement for attachment of a gas burner to an opening for guiding the burner includes an attachment arrangement that is used in the cooking area which comprises a burner with a circumferential collar that is molded onto burner body above the cooking surface for tight seating on the cooking surface top side. The connection is made by friction or tension of the burner body with at least one spring element disposed below the cooking surface.

Abstract: Unit with at least one plate made of a material, which material is permeable to thermal radiation, such as glass ceramic, glass, ceramic or a similar material, as a surface for cooking, frying and/or keeping warm. The unit with at least one plate is on a frame construction with different types of adjustable heat sources distributed underneath and on the plate. Some of the heat sources are distributed under the plate in the form of radiant burners and act indirectly by radiation through the plate. Other heat sources are located above the level of the plate in the form of open atmospheric or atmospheric pressure gas burners and transmit heat directly by producing open flames. The respective heat sources correspond to the cooking, frying and/or warming positions.

Abstract: Gas cooking appliances having glass or glass-ceramic plates for cooking surfaces also having gas-radiation burners that are positioned below the plate or atmospheric burners that are recessed in the plate. With gas radiation burners, care must be taken to ensure a thermally advantageous discharge of exhaust gases that are produced and with atmospheric burners, care must be taken to ensure an adequate supply of primary air. Accordingly, the glass or glass-ceramic plate forming the cooking surface is partially bent out of the cooking surface plane to form an adhesive-free exhaust air duct or fresh air opening in the bent area. The exhaust air duct and fresh air opening are free of ventilation lattices.

The ceramic carrier of the heating element can rest with overlap on regions of the surface which deviate from the main plane of the plate-like surface so as form elevations running linearly, such as cone frustums, spherical segments and/or cones, and which define the edge of the cutout. This elevated rest of the heating element serving as a bearing, and the underside of the surface serving as an abutment for a cover arranged below the main plane of the surface and closing off the cutout downwards, and the heating element being fixed positively and non-positively in the cutout of the surface by way of fastening elements connected firmly to the heating element and firmly and releasably to the cover.

Abstract: The invention is directed to cooktop apparatus wherein a cooktop panel is seated in a frame and is made of glass ceramic, glass or ceramic. The cooktop panel has a cutout for accommodating an atmospheric gas burner in the cooktop panel. A component assembly holds the gas burner in the cooktop panel and the component assembly includes a collar annularly overlapping a portion of the panel in the region of the cutout. The collar has an inner region defining an edge which, in turn, defines a first abutment for engaging the gas burner. A resilient metal element is attached to the gas burner and extends outwardly from the gas burner to engage the panel on the lower side thereof. The lower side of the panel defines a second abutment against which the resilient metal element applies a force F to hold the gas burner on the panel via the collar and the resilient metal element. A seal is sandwiched and clamped between the collar and the panel thereby preventing any spillage from reaching the frame through the cutout.
