Abstract: A device for adjusting the armature stroke in a reversible linear drive unit comprising an excitation coil and an armature displaceable in the magnetic field of the excitation coil according to a linear oscillating motion at a predefined armature stroke. The device comprising systems for detecting the current armature position, systems for measuring the actual excitation coil current and systems for adjusting the excitation coil current in such a way that the armature is exactly supplied with electric energy for obtaining the aptitude of oscillations of the armature stroke during each half-wave of the armature motion.

Abstract: A device for sucking up particles to be collected, in which at least one collecting compartment for collecting these particles is connected via an inlet opening of a partition to a suction device located inside at least one accommodating compartment. The collecting compartment is connected to the suction device in a manner that enables an airflow to be guided from the collecting compartment to the suction device. The partition contains, as an inlet opening, an air guiding funnel whose inlet surface forms a significant portion of the partition surface.

Abstract: An electric motor has a hollow-cylindrical motor housing containing end plates that are mounted in the motor housing via respective centering flanges. A discrete electrical component is connected in parallel to electrical connections of the electric motor that are formed by contact elements disposed on the first end plate. The component is linked with at least one of the contact elements via a lead. The lead is inserted in a first, substantially V-shaped groove that tapers in the direction of insertion. The groove is provided with a recess into which the contact element can be pressed.

Abstract: A refrigerating device including a hollow-walled housing surrounding a first and a second storage compartment. A vacuum pump is controllably connected via a suction line to the hollow chamber of the housing and to one of the storage compartments. The pump is controlled to maintain a desired pressure range in both the housing and the storage compartment.

Abstract: A drying rack for the stationary drying of articles to be dried, which can be installed in the drum of a clothes dryer. The articles can be knitwear or shoes that must not be moved when dried even when the drum turns. For articles, especially, wool articles, to dry faster, the drying rack has at least two spaced-apart surfaces disposed one on top of the other on which the articles to be dried can be spread, thereby substantially enlarging the surface of the articles to be dried. As such, the drying air current can better remove the moisture and larger individual wool articles can be dried in the clothes dryer.

Abstract: A household appliance with a simple to use selected operating language includes activating the programs by taking into account the special characteristics of specific languages. The household appliance includes a display unit that displays all information in a simple language. The selected language, the selected programming of the household appliance, and the selected additional functions in addition to error messages are shown on the display unit so that operational mistakes are basically prevented.

Abstract: There is provided a filter device that enables less frequent manual or self cleaning of the filter surface. The filter is particularly suitable for an aquiferous domestic appliance, such as a dishwashing machine, in which the cleaning effect occurring with alternating pumping is further increased, such that manual cleaning of the filter surface need take place less often, or, respectively, self-cleaning of the filter surface occurs.

Abstract: A cooking appliance including at least one heating unit for heating a cooking area and including at least one extractor fan. At least one parameter of the extractor fan can be controlled to different values by a control unit, regardless of the selected cooking mode. At least one parameter value is stored in an electronic storage unit.

Abstract: The invention relates to a method and a circuit arrangement for preventing overheating of a cooking appliance. The arrangement includes a power circuit with a heating element and a control circuit with a coupling switch. The control circuit and the power circuit are coupled by the coupling switch. The arrangement further includes a safety switch to the control circuit. The coupling switch interrupts a power supply to the power circuit to the heating element when a limiting temperature in the cooking appliance is exceeded.

Abstract: A self-closing door structure includes a frame, a door pivotally mounted on the frame, and an arm mounted on the frame and pivoting between two stop positions. A first stop position corresponds to a closed position of the door and the second stop position corresponds to an opened position of the door. Also included is a spring coupled to the arm and acting upon the arm in a direction towards the first stop position when the arm is located in a position between the first stop position and a dead center position of the spring. The arm has a driving element for coupling the motion of the door to that of the arm and is disposed for engaging with an engaging point of the door over the course of a closing motion of the door and for disengaging over the course of an opening motion of the door.

Abstract: A central power supply device for an electric supply of a domestic appliance and an electronic control unit of the appliance is connected to an output side of an interference suppression filter. The aim is to integrate recurrent, standardized devices in such a way that components are not allocated functions that do not belong to their task domain. To achieve this, an automatically controlled network disconnection device is integrated, together with the interference suppression filter, into the phase conductor, or in addition into the neutral conductor. A power supply device for an electronic control logic circuit of the network disconnection device is connected to the input side of the network disconnection device and the control output of the control logic circuit is connected to the control input of the network disconnection device.
