Abstract: A device for steam generation has a device housing, a heating chamber for water with a water inlet for connection to a water supply and a steam outlet. A heating element is provided on the heating chamber for heating up and evaporating water therein and has a metallic heating element carrier and heating conductors arranged thereon, preferably as thick-film heating conductors. The heating chamber and the heating element are arranged in the device housing. The heating element forms a wall of the heating chamber and is connected in sealing manner to other walls of the heating chamber. The heating chamber is in one extension direction longer than it is wide and deep in both extension directions vertical thereto. An electrical connection device for the device is provided laterally on an elongated side of the heating chamber on the device housing, in particular projecting laterally from the device housing in order to achieve a flat design.

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: 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.

The connection device is attached at the contact fields with the contact feet and is electrically connected thereto. Additional electrical insulation is arranged between the connection device and the outside of the carrier. This can be, for example, one of several individual insulating layers that together form the entire insulating layer.

Abstract: The invention relates to a heating device having a flat expanded support and at least one heating conductor assembly thereon which is electrically connected by means of two connection contacts. The heating conductor assembly has a plurality of heating conductors which are connected together at connection points and are wired as a whole so as to form parallel and series circuits between the connection contacts.

Abstract: An evaporator device for water, which is intended to produce steam for, for example, a steam cooking device, has a container which is closed apart from a water inlet and a steam outlet, and has heating elements on the outside of the container. An inner body is arranged inside the container and is, everywhere on its outer surface, which faces toward the heating element, spaced apart from the inner side of the container. Said inner body is permeable to steam and water and consists of a non-solid material or of a porous material or of a fabric material.

Abstract: A heating device has a support and a sheet-like electrical conductor, which is arranged on the support and runs between a first terminal and a second terminal, the at least one heating conductor including carbon-based material as heating conductor material. A heating conductor thickness between the electrical terminals may at least partially vary and not be constant for the adaptation of a local heating output. In addition, the heating conductor may be either rectangular and short or in the form of a circular ring.

Abstract: A heating device for heating water has a carrier to which at least one heating element is applied, the heating element having one or more heating conductors which are connected one behind the other. The heating device has a flat dielectric layer which substantially covers the heating conductors or the heating element. An electrically conductive connection area is in each case provided on both sides of the dielectric layer with the same coverage. At least one of the connection areas is connected to a controller for evaluating a leakage current as current flows through the dielectric layer, and the heating element is connected to measuring means for monitoring a heating conductor current through the heating element. Both the leakage current and the heating conductor current are monitored over time and faults can be identified if there are conspicuous changes.
