Abstract: The invention provides a pump, in particular for water-bearing domestic appliances such as dishwashers, washing machines or the like, comprising a pump housing and a heater device which is in thermal contact with the liquid-bearing interior of the pump housing. The pump according to the invention is simple and cost-effective to produce. For this reason, the pump housing (2) is produced at least partially from plastic, with the heater device (11, 12) being at least partially connected to the plastic in an interlocking manner.

Abstract: The invention relates to a friction damper (1), particularly for drum washing machines having a spin gear, with a housing and with a moveable tappet (4) which is arranged in the housing (2), parallel to the housing longitudinal axis (2a), and is led out of the housing (2) and which is provided at its end located in the housing with a moveably guided friction lining (8). The invention is distinguished in that the friction lining (8) or a body carrying the friction lining (8) is provided with a receptacle (22) for receiving an expandable body (23).

Abstract: A valve and a method for producing a valve, in particular for coolant circuits, having a valve seat (2) including a valve seating element (1) for a valve body (3) by stamping the pole shoe to form at least one sealing surface (8) to avoid the disadvantages of the prior art. This is achieved according to the invention by forming at least one sealing surface (8) to form a novel sealing element (1) by utilizing a stamping element to form a stamped surface of the novel valve with a valve seating element.

Abstract: The present invention relates to a frictional damper, especially for cylinder washing machines with spin cycle, having a housing (2) and a movable plunger (4) which is arranged in the housing (2) parallel to the housing longitudinal axis, is led out of the housing (2) and is provided with at least one window (6) at its end located in the housing (2), at least one mounting part (7), movable longitudinally relative to the plunger (4), for mounting a friction lining (8, 9) and at least one amplitude-dependent impact element (15, 16) for braking the movement of the mounting part (7) being provided in the window (6), this frictional damper being characterized in that the impact element (15, 16) is arranged between an inner surface (20, 21) of the window (6) and an outer surface (18, 19) of the mounting part (7).

Abstract: The invention proposes a household appliance, in particular a dishwasher, a washing machine or the like, having a liquid circuit and a pump which has a pump casing which comprises a heating element (3) for heating the liquid, which element is adapted, with a heat-conducting contact area (20), to the outer shape (2) of the casing with an at least partial form fit. In this case, the heating system of the household appliance according to the invention is intended to have an improved efficiency. This is achieved, according to the invention, by the contact area (20) being at least half the size of the entire outer area of the heating element.

Abstract: A centrifugal pump (1) is proposed, in particular for household appliances, such as washing machines or dishwashers, which comprises a pump housing (2) having an axial inlet (11), an outlet (12) and a heating element, wherein the pump housing (2) incorporates a rotatably mounted impeller (4) and a flow channel (15) enveloping the impeller (4) and heating element. The centrifugal pump (1) according to the invention is intended to have improved efficiency. This is achieved by having the flow cross-section of the flow channel (15) increase along the periphery toward the outlet (12).

Abstract: A valve and a method for producing a valve, in particular for coolant circuits, having a valve seat (2) including a valve seating element (1) for a valve body (3) by stamping the pole shoe to form at least one sealing surface (8) to avoid the disadvantages of the prior art. This is achieved according to the invention by forming at least one sealing surface (8) to form a novel sealing element (1) utilizing a stamping element to form a stamped surface of the novel valve with a valve seating element.

Abstract: A dishwasher (1) is proposed, in which the program sequence can be controlled as required. According to the invention, this is achieved by providing a radar sensor (12).

Abstract: A dispensing device for dispensing liquid detergent in dishwashers is provided in which the detergent is fed into the wash area of the dishwasher only after the second actuation of the actuating member. This is achieved by providing: a barrier on the discharge side for the detergent in the operating position, which barrier is sequenced to follow a supply chamber. A return opening is provided to return the retained detergent in the fill position.

Abstract: A dispenser for a dishwasher is proposed containing a housing 1 partially projecting in the installed condition through a door recess into the interior of the door of the automatic dishwasher and located partially within the wash area. The housing consists of two housing sections which preclude housing leaks into the interior of the door. This is achieved by providing an inner section located only partially within the interior of the door and projecting into the wash area, and an outer section located completely on the side of the wash area.

Abstract: The invention relates to a method for operating a household dishwasher, said dishwasher being equipped with a program selection device and a combined device for adding a detergent and a clear rinse agent to the washing area. The aim of the invention is to improve the cleaning effect. To this end, the clear rinse agent is added not only once during the last wash cycle, but on several occasions at various times during the wash program. Each of these processes is characterized by an adjustable number of equal quantities or a non-adjustable number of variable quantities of a clear rinse agent. A metering device for carrying out the inventive method comprises a reservoir, a temporary storage unit and a metering chamber. Both the temporary storage unit and the metering chamber can be configured with an adjustable volume.
