Abstract: A cooktop includes an at least partially transparent surface formed of glass or glass ceramic and having burner regions with peripheral and inner portions. Heating elements are disposed beneath the surface in the vicinity of the burner regions. A lighting apparatus visually indicates a temperature of the surface which exceeds a predetermined temperature at which the surface is permitted to be touched. The lighting apparatus has a temperature-dependent switch thermally coupled to the surface. The light devices controlled by the switch. Each of the light devices is disposed in one of the portions of a respective one of the burner regions.

Abstract: A control apparatus for heating, defrosting and/or cooking foods to be heat-treated by exposure to microwave energy at a given location inside a closed cooking chamber includes a microwave generator beaming microwave energy into the cooking chamber, and a sensor detecting the state of the food and controlling the energy beamed into the cooking chamber. The sensor is disposed in the cooking chamber filled with microwave energy between the microwave generator and the given location for food exposed to microwave energy, for detecting a value for microwave energy potential and controlling the output of the microwave generator.

Abstract: A heating element for thermal household appliances includes an inherently stable carrier element having a heating surface in close thermal contact with a substance to be heated, and at least one heating resistor in the form of at least one flat heating conductor strip supported by and closely thermally coupled to the carrier element.

Abstract: A temperature control apparatus for a baking oven includes a baking heating element for heating the baking oven, a grill heating element disposed in the baking oven, a first thermostatic baking oven regulator manually settable to different temperatures for the baking heating element, a second regulator manually settable to different heating stages for the grill heating element, and a single setting device for setting and operating the first and second regulators, the setting device having a first control range in which the first regulator is adjustably controlled and a second control range in which the second regulator is adjustably controlled.

Abstract: A heating device for radiation heating units heated by electric energy includes a radiation heating region and a combination of high-temperature radiation heating elements and normal-temperature radiation heating elements disposed in the heating region.

Abstract: Baking oven including chamber walls defining a baking oven chamber, a door for closing off the chamber, a broiler heating element and at least one further heating element being disposed in vicinity of opposite chamber walls, and air blowing and guiding means disposed between the heating elements for generating an air stream being in the middle of the chamber and at least approximately parallel to and maintained at a given distance from the chamber walls.

Abstract: In a double baking oven unit having two baking ovens disposed one above the other and enclosed in a common housing, one of the ovens being a microwave oven, and switching, control and operating devices for both of the ovens disposed in an upper space in the housing, cooling-air channels formed with inlet and outlet openings provided outside the two baking ovens, shielding plates thermally shielding the lower baking oven from the upper baking oven and from the cooling-air channels, the cooling-air inlet opening being located at a lower limit of the housing below the lower baking oven and below a shielding plate associated therewith, the cooling-air outlet opening as well as a blower being connected to an exhaust channel disposed above the upper baking oven.

Abstract: Dish for holding food to be heated in a microwave cooking chamber in which the dish bowl provided for holding the food is made to obtain high absorption of high-frequency radiation and the handles and/or base are made to obtain low absorption of high-frequency radiation. In one form the dish has two dish bowls with a common bottom wall, and with one dish bowl having its inner surface covered with a high-frequency radiation-absorbing coating, and the other dish bowl having its inner surface covered with a high-frequency radiation-reflecting coating.

Abstract: A range top having a plurality of main cooking stations defining discrete cooking areas spaced from one another and being switchable on and off by switching elements individually connectible to the main cooking stations, includes an auxiliary cooking station disposed in vicinity of at least one of the main cooking stations and being conformed to and contiguous with the one main cooking station so as to define therewith a substantially continuous enlarged cooking area.
