Disclosed is a modularly constructed and variably configurable cook top arrangement of ready-made single modules each containing in a frame construction all parts necessary for operation as a burner module, exhaust component, blower unit, control module, signal and display unit, or other components, having a glass ceramic cook top in which the individual modules have shaped metal parts to which materials for thermal insulation are joined, and which have fastening means by which the modules can be arranged with one another and with the frame and can be fastened releasably to form a single functional unit, and on which openings, bores and recesses are provided as an assembling means for fastening the parts necessary for operation and for leading in and fixing the wiring and/or the ignition, control, and safety and indicating systems.

Modular kitchen range arrangement under a glass ceramic cook-top

The cooking apparatus includes a glass or glass-ceramic plate (,) providing a cooking surface with a cooking area and provided with a throughgoing opening (,) in the cooking area; a gas burner (,) arranged in or under the throughgoing opening (,) in the glass or glass-ceramic plate (,), which has a burner ring (,) for supporting an open flame (,); a cooking vessel support (,) arranged on the glass or glass-ceramic plate over the throughgoing opening (,) which has a resting surface for a cooking vessel (,) and a device for supplying a mixture of combustible gas and primary air to the burner ring (,) 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 (,). 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 (,) can be substantially reduced to less than 10 mm without impairing the combustion process.

A gas burner has a perforated, hollow body around and defining a combustion chamber. Gaseous fuel is fed to one side of the body, combustion occurs on the other side and the perforations provide a spatial connection between the fuel feed side and the combustion side. The new burner reduces exhaust gas emissions and offers a wide range of performance in the amount of heat energy provided, in the permissible range of gas pressure and in the range of fuels and fuel/air mixtures that can be used with it.

Gas burner with pollution-reducing features

The invention is directed to an arrangement for adjusting a pressure-fluctuation free supply of gas and for controlling an operating pressure of an air/gas mixture to a radiation-gas burner of a gas cooking apparatus. The radiation-gas burner has a burner chamber and is mounted in a housing below a cover plate. The arrangement includes a gas supply conduit connectable to a gas source for receiving the gas and a pressure controller is mounted in the gas supply conduit for controlling the pressure of the gas to a constant operating pressure of at least 2.5 mbar above atmospheric pressure. A control unit is connected to the pressure controller for receiving the pressure-controlled gas and for metering the gas to the radiation-gas burner. The control unit includes a valve block having at least one exchangeable nozzle adapted to the type of gas from the gas source and a feed conduit has a clear cross-sectional area and communicates with the burner chamber. The feed conduit has an inlet opening adjacent the nozzle. A blower blows air into the apparatus to generate an overpressure whereby the gas metered by the control unit through the nozzle entrains air to form an air/gas mixture entering the feed conduit. An insert is mounted in the feed conduit for reducing the cross-sectional area of the feed conduit. The insert is selected so as to reduce the cross-sectional area to enable the radiation-gas burner to operate at a predetermined efficiency irrespective of the fluctuations in the pressure of the gas and the changes in type of the gas.

Arrangement for adjusting the gas supply and the control of an operating

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.

Gas cooking appliance

Apparatus for limiting the temperature of a cooking location of a type having an electrically conductive burner housing forming a heating chamber, includes a temperature sensor including an outer tube and an inner rod received within the tube, a switch base carrying at least one contact which is actuated by the temperature sensor, an electrode at least partially positioned in the heating chamber and secured to at least one element selected from the group consisting of temperature sensor and switch base, and a current measuring device having a first terminal connected to the electrode and a second terminal connected to the burner housing.

The gas burner according to the invention has a burner chamber housing, a mixing pipe connected to the burner chamber housing for supplying a gas/air mixture, a burner plate made of fibrous material and attached to the burner chamber housing at edge regions of the burner plate, a blower for supplying air to make the gas/air mixture, and advantageously an ignition device, a safety device and a temperature monitoring device. A central region of the burner plate is advantageously directly or indirectly connected to a corresponding central region of the burner chamber housing to suppress burner plate vibration during start-up of burner operation to prevent sound generation during the start-up and minimize the pressure drop in the burner chamber. In a preferred embodiment a recessed portion formed in a middle region of a base plate of the burner chamber housing is shaped to contact on a central region of the burner plate and a temperature-resistant adhesive is used to connect the burner plate and the recessed portion of the burner chamber housing.
