Abstract: A steam generator has a water container and an upper heating device and a lower heating device, a first temperature detection device covering a temperature detection area including the area covered by the two heating devices, a control device for monitoring and evaluating the first temperature detection device and for controlling the activation state of the two heating devices. For operation of the steam generator, water is filled into the container, at least one of the two heating devices is activated for generating steam for an operation of a steam household device, wherein finally this operation is over. Then at least the lower heating device is activated, until the first temperature detection device detects that a pre-defined first temperature threshold has been reached, upon which the lower heating device is deactivated. Remaining water is pumped off from the water container for a pre-defined first pumping duration.

Abstract: In a method for operating a heating device, fluid is initially introduced into a fluid chamber, then the heating elements of the heating device are switched on and a leakage current is detected as a temperature-dependent current flow through a dielectric insulation layer. A supply voltage of the heating devices is measured and is taken into account in an evaluation of the temperature at the fluid chamber as a function of the leakage current. The leakage current is converted into a leakage voltage by means of a resistor, which is then divided by the measured supply voltage. Subsequently, the quotient obtained may be multiplied by a compensation value in order to obtain a normalized leakage signal, which is normalized to a base value of the supply voltage.

Abstract: A steam generator has a water container and an upper heating device and a lower heating device, a first temperature detection device covering a temperature detection area including the area covered by the two heating devices, a control device for monitoring and evaluating the first temperature detection device and for controlling the activation state of the two heating devices. A flat first temperature detection device covers the outside of the container, and a second spot-like temperature sensor is located on the water container in a region of an upper border of the upper heating device. Both temperature detection devices are used to activate and deactivate the two heating devices such that at first the lower heating device is activated to start generating steam as fast as possible.

Abstract: In a method for the production of a heating device, comprising a support that is curved along one direction and at least one flat thick film heating element disposed thereon, the support and/or the heating device itself are processed from a tube, in particular a circular-cylindrical tube. For that purpose a tube wall is severed in one direction which does not exclusively have a peripheral direction component so that the support is not a circumferential tube. The thick film heating element can be applied before or after the severing.

A thermogenerator is arranged above the gas burner body, advantageously arranged concentrically relative to said gas burner body and with the same shape and size, wherein the thermogenerator is heated by said gas burner body. The thermogenerator bears against a cooler pot base by way of its upper face. The thermogenerator generates electrical energy which is used to operate a control of the gas cooktop and which can be stored.

The hot side is provided close to the heat source with good thermal coupling to the said heat source, and the cold side is routed to the surrounding area, to a baking-oven muffle or to a cooking plate of the heat-storage cooker. Therefore, an electronic control means can be operated even in the case of a heat-storage cooker without an electrical connection.

Abstract: A method for regulating a cooking process of a cooking product in an oven of a steamer, during which the moisture in the oven coming from the cooking product is at least periodically determined over time by a moisture sensor. During a measuring phase there is no introduction of steam into the steam oven and the moisture sensor is evaluated. For a given cooking process with fixed times for the supply of steam, on the basis of the moisture sensor evaluation during the measuring phase, the end of cooking is determined. Prior to the measuring phase and during a steam phase, steam is introduced into the oven, the steam supply being terminated following the steam phase and prior to the measuring phase during a ventilating phase. During the ventilating phase the steam concentration in the oven is greatly reduced.

Abstract: A memory has coding units that are used for allocating any one of redundant lines at a time to any one of first lines on an address basis. Each coding unit has a programmable activation unit. In a first programming state of the activation unit, the associated coding unit, when programmed, allocates a complete redundant line to a complete first line on an address basis. In a second programming state of the activation unit, the associated coding unit, when programmed, allocates only one of the subregions of one of the redundant lines to a corresponding subregion of one of the first lines on an address basis.
