摘要： 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.

摘要： A water bearing appliance, control method, and system are provided. Operating data from appliances are transmitted to a receiver over a network such as the Internet. Maintenance, cleaning, and repairs are initiated based on the operating data, and can be triggered remotely and automatically. A machine learning model(s) is trained according to operating conditions of various appliances and respective outcomes, such as maintenance, repairs, damages, life expectancy, and/or the like, to learn correlations therebetween. A digital twin appliance data object is generated for an appliance and applied to the machine learning model(s) to provide a predictive maintenance data object. Cleaning regimens, maintenance, repairs, and/or the like are configured to particular operating circumstances of an appliance.

摘要： A washing machine has a drum-receiving container and a rotatable drum therein and a water routing system which has a water inlet from an external water supply into the washing machine, water lines and valves, as well as a water outlet from the washing machine. An injection device for water into the drum, a container outlet at the bottom of the drum-receiving container, a pump, a filter and a washing machine controller are provided. The water routing system drive has an adjustable pressure-reducing device arranged between, on the one hand, the water inlet into the washing machine and, on the other hand, the pump and/or the injection device. The pressure-reducing device is connected, for adjustment, to the washing machine controller.

摘要： A hob has a radiant heating device, a hob plate above said radiant heating device and a safety temperature limiter between said radiant heating device and hob plate, which safety temperature limiter is designed to deactivate the radiant heating device when a switch-off temperature is reached. In order to actuate the radiant heating device, a cooking vessel is first placed on the hob plate above the radiant heating device and then the radiant heating device is activated and at the same time detection of a first switch-on time starts. When a switch-off temperature is reached at the safety temperature limiter, the radiant heating device is deactivated by said safety temperature limiter. The first switch-on time that has elapsed up to that point between activation and deactivation of the radiant heating device is detected and compared with a predefined limit switch-on time. If the first switch-on time lies below the limit switch-on time the radiant heating device is switched off.

摘要： In the interests of improved temperature detection and temperature control of a cooking appliance on a hob by means of an induction coil, the cooking appliance has specific and individual identification. This can be contained in an NFC tag, by way of identification means. This identification can be read out on a hob, either by means of the hob itself or by means of a mobile telephone, and transferred to a database in an Internet cloud storage facility. From the latter, specific characteristics for this cooking appliance can be downloaded and employed for a temperature-controlled heating of the cooking appliance.

摘要： A washing machine drawer (50) in a washing machine (11) has a drawer body (51) with several chambers including chambers (63) for filling in detergents or additives for a washing process, sensor means (71, 76, 80) in the receptacle for analyzing water transported to the sensor means and a receptacle communication module (56) for a data connection to the outside. A control device (40) of the washing machine is communicating with the receptacle communication module (56) to receive data about analysis results from the sensors for adapting a washing process. The drawer (50) may be exchangeable to provide the washing machine with more and up to date features. The drawer (50) may also have a receptacle control (54) provided with a powerful controller to overtake some functions of the washing machine (11) besides controlling the sensor means.

摘要： The invention relates to a heating circuit for induction heating coils of an induction cooking hob and to an induction cooking hob including such a heating circuit. In the heating circuit, there are in each case two auxiliary half bridges interconnected to excite a respective resonant circuit for an induction heating coil such that the resonant circuit is excited by a full bridge. Thereby, lost heat is considerably reduced. Via a connecting device the auxiliary half bridges can be controlled to excite induction heating coils, which are partly or fully covered by a cooking vessel.

摘要： A heating device comprising a temperature measuring device has a sheet-like carrier, at least one heating conductor on said sheet-like carrier, an elongate electrode on the sheet-like carrier and a layer structure on the carrier with an insulation layer between the heating conductor and the electrode. A measuring apparatus for detecting local high temperatures at the heating device is connected to the electrode and to the heating conductor. Said measuring apparatus detects a temperature-dependent leakage current through the insulation layer between the heating conductor and the electrode and evaluates this as a measure of a local change in temperature at the heating device. The electrode consists of a material with a temperature dependence of its electrical resistance of between 0.0005/° C. and 0.01/° C. in a temperature range of between 0° C. and 200° C. A temperature measuring device is connected to the electrode for the purpose of measuring a temperature at the electrode using the temperature dependence of the electrical resistance of the electrode.

摘要： In a method for controlling a relay with a relay contact, switching as an opening operation or a closing operation at the relay is temporally captured with respect to accurate opening or closing of the relay contact in comparison with a switching voltage zero crossing of a switching voltage to be switched. An actual switching time is determined and is corrected by means of further capturing of switching operations. A microcontroller is used for this purpose, and the signals can be digitally captured, that is to say at an A/D input.

摘要： A washing machine has a drum, a sump underneath the drum, a water circulation including an extractible drawer for introducing detergent or additives, the water circulation being in fluid connection to detecting means for detecting microfibers or contamination in the water and a circulation pump and pipes for circulating water. A method for its operation comprises the steps of branching off an amount of water circulating in the circulation and transporting it to the detecting means for being analyzed and analyzing the water in the detecting means. Depending on the result of this analysis, a filtering process with filtering means for filtering out the microfibers from the water is activated. The microfibers that have been filtered out can be collected and then removed easily from the washing machine.
