摘要： A washing machine in the form of a water-guiding domestic appliance has a water tank with a drum as treatment compartment therein, wherein the water tank has an outflow at the bottom. The washing machine also has a pump, a filter between the outflow and the pump and a water-guiding system with water lines, valves, the pump and the filter. A flexible or bendable flex line adjoins the outflow, which line extends at an angle of between 15° and 0° to the vertical from the outflow at the bottom, wherein a substantially horizontally extending telescopic line of variable length, which leads to the filter, adjoins the flex line. A drain valve, which may be configured as an actively closable valve or as a nonreturn valve, is arranged between the telescopic line and the filter. The filter is in turn arranged at a short distance downstream of the drain valve.

摘要： In a method of operating a washing machine, different values for the power required by a drive motor of a drum of the washing machine to accelerate the drum from 30 rpm to 80 rpm are measured and stored as reference values. They can be differentiated by weight or load of laundry, potentially also by different types of laundry. These values are then compared to values derived from an actual washing or dry-spinning process, respectively. As a result of this comparison, it can be determined which values actually measured correspond sufficiently to stored values, and then the load can be determined from this result.

摘要： A method for controlling an induction coil on an induction hob involves a power generation for a primary power on the induction coil for power transmission to an electrical consumer put onto a cover above the induction coil, which consumer has a receiver coil and an electrical load connected thereto, being adjusted. The induction coil forms a primary-side resonant circuit with a capacitance connected in series, and the induction coil and the receiver coil are coupled in the style of a transformer such that a current in the induction coil induces a voltage in the receiver coil with a flow of current and generation of the secondary power in the load of the electrical consumer. The control means can attempt to adjust the desired secondary power to a steady state using maximum modulation of the voltage effectively applied to the primary-side resonant circuit, as second manipulated variable. The primary power is decreased in a first step by virtue of the voltage effectively applied to the primary-side resonant circuit, as second manipulated variable, being decreased before the operating frequency as first manipulated variable is increased in a second, subsequent step.

摘要： 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.

摘要： An expansion system for temperature detection by means of thermomechanical expansion and movement has an expansion receptacle, an elongate fluid line which is connected in a fluid-conducting manner thereto, and a switching means which is mechanically operatively connected to the expansion receptacle for the purpose of actuation of a switching process of the switching means at a settable actuation point. A working fluid is contained in the expansion receptacle and in the fluid line. Furthermore, an activation material which is formed to change, upon contact with the working fluid or upon mixing with the working fluid, said working fluid with regard to its volume and/or its flowability is contained in the expansion system.

摘要： In a method for operating a cooktop having a cooktop plate and adjacent heating means arranged thereunder along a straight line, and a pan detection means for detecting a relative coverage of each heating means by cooking vessels placed thereover, it is detected in a preceding step over which of the heating means a cooking vessel has been placed and thus that a relative coverage is present. In a subsequent step, the pan detection means is used to detect how great is the relative coverage of each covered heating means, and from this result and a comparison of these results for each heating means a case analysis is performed into one of several cases. For a 1st case, in which it is detected for the three heating means arranged along the straight line, that the relative coverage of the middle heating means is less than the relative coverage of the other two adjacent heating means, it is determined that no cooking vessel has been placed over the three heating means which contiguously covers all three heating means, but rather that at least two cooking vessels have been placed over the three heating means.

摘要： A heating device in the form of a radiant heating device for a hob has a sheet-like support with a support top side, with at least one heating element on the support top side, which heating element is highly corrugated and runs in tracks in a laying pattern. The heating element has at least two heating conductor strips which each have lateral sides and a top edge and a bottom edge. These at least two heating conductor strips are placed together or placed on one another by way of their mutually facing lateral sides and are at least partially in contact. The at least two heating conductor strips are connected to one another in a fixed and non-detachable manner, advantageously before corrugation.
