Abstract: In a method for operating a cooking appliance, a preparation program of the cooking appliance is carried out when preparing an item to be cooked in a cooking chamber of the cooking appliance, while a door of the cooking appliance closes the cooking chamber. The door is automatically opened by a door opening device of the cooking appliance when an end time of the preparation program is reached, and the door is maintained in an open state for a time period determined before opening and/or a time period permanently defined before opening.

Abstract: An operating device includes at least one panel unit which has at least one operating region and a lighting unit configured to back-light and/or to transilluminate the at least one operating region. A sensor unit including at least one at least partly transparent support element and at least one sensor element which is arranged on the at least one support element as an etched structure is arranged at least partly between the lighting unit and the panel unit.

Abstract: A household appliance includes a mechanical relay, and a switch detection device which is configured to detect a switch of the relay. The switch detection device includes a measuring apparatus to measure an electrical coil current, which flows through the relay when the relay is switched, and an evaluation device to detect the switch of the relay on the basis of the measured coil current. In a method to operate a household appliance, an electric coil current which flows through the relay when the relay is switched is measured, and a switch of the relay and/or a delay time of the relay is detected using the measured coil current. The invention can be advantageously used on cooking devices, in particular ovens, in particular for switching heating elements.

Abstract: A control and a method for controlling a domestic appliance, especially a cooking device, including a display unit for displaying information, the control controlling the display of information on the display unit. The control includes a separate input element for retrieving information so that the user can retrieve the information by actuating the separate input element and the information is then displayed on the display unit. Particularly, the information can be retrieved from different operating states of the domestic appliance.

Abstract: A method for exchanging data between an electric device and a user interface via a data network. Control or status information data is exchanged between the electric device and the user interface in the form of data packets. A complete data record containing all control or all status information that is relevant for the control or for the status of the device is transmitted with each packet transmitted.

Abstract: A lighting device for an extractor hood includes a light source having at least a plurality of controlled LEDs and an extractor hood control device. The light source is connected to the control device. The light source can also include halogen and/or incandescent lamps. The control device can vary a luminous intensity of at least some of the LEDs and/or the lamps, alter a diode current of at least some of the LEDs, and/or drive a subset of the LEDs or lamps.

Abstract: A method of and device for checking a device for influencing the temperature of a baking oven includes switching on devices for influencing the temperature of a baking oven for a predetermined time and subsequently comparing a measured temperature obtained with a predetermined comparison temperature. A fault signal is output dependent upon the comparison result.

Abstract: A control unit for setting operating functions and operating parameters in an electrical household appliance includes a control knob retained on a control area. The control knob can be rotated about a knob axis for setting the operating parameters of, for example, a heating level. In order to simplify operation of the control unit, the control knob can be tilted or pushed out of an initial position or knob axis, into a selection position in order to select a specific operating function, for example a specific cooking position.

Abstract: An electric oven with an oven muffle which can be closed by a door and in which a cooking-product support can be held on a holder element. The cooking-product support has its own cooking-product support heater element, and via a power supply element, the cooking-product support heater element can be fed with an electric voltage of the oven, is known. In order to keep the outlay for providing electrical contact for the cooking-product support heater element low, the holder element for the cooking-product support at the same time serves as the power supply conduit or element.

Abstract: A cooktop assembly has a glass-ceramic cooktop, a radiant heater defining a heating zone of the cooktop, and a metal sensor disposed under the cooktop inside or outside the heating zone. A mains voltage contact protector for the sensor includes operating the sensor at a higher-frequency operating point than for normal operation, and a rejection filter being connected to the sensor and dimensioned for mains voltage contact protection.
