Abstract: A set of two burners is provided for a glass-ceramic cook top. Below the usual glass-ceramic plate, the set of burners includes an inner disk-shaped burner, radially and circumferentially surrounded by an annular burner. Each burner has an inlet for a gas-air mixture, a chamber, and a honeycombed, perforated ceramic plate in which combustion is carried out, and from which infrared energy radiates for heating items which may be supported on the overlying glass-ceramic plate. The upper surfaces of the two perforated ceramic plates are preferably flat, and may be coplanar, or disposed at two different levels.

Abstract: A glass-ceramic gas cooker top is provided with a piezoelectrically operated igniter for a pilot light for the burner. When the pilot light is lit, it heats a filament that is visible through the cooking vessel support plate of the cooker top. The burner is provided with a thermostatic valve, having a temperature-sensing bulb applied to the underside of the cooking vessel support plate.

Abstract: An arrangement for cooking by combustion of gas in which a thermal fluid flows between a boiler, in which it is heated, and heaters where it releases the heat received, the thermal fluid returning to the boiler. The heaters are provided with a cavity limited at the top by a plate generally flush with the hob of the arrangement. The thermal fluid is preferably vaporized in the boiler and is condensed in the heaters. The arrangement facilitates cleanliness of the hob and provides for correct exhaustion of the combustion gases.
