摘要:
An apparatus and a method for repeated, automatic metering of precisely metered quantities of a powdered detergent into water-carrying cleaning machines, in particular household dishwashers and household washing machines, include a detergent holder and a metering and dispensing device having a movable metering device with at least one metering receptacle. The interior of the detergent holder and a guide of the metering and dispensing device are acted upon continuously by a stream of compressed air. Therefore, clumping of the highly hygroscopic powdered detergent and an expensive, complex apparatus, which requires a high drive torque and a high air pressure, are avoided. The metering device has only one metering receptacle. The metering and dispensing device has two chambers communicating with one another. The detergent fed into the first chamber is fed gradually, during the motion of the metering device, into the second chamber, which has an opening toward the treatment vessel. The treatment vessel-side opening of the second chamber is closed by a lid connected to the metering device. The lid, in the dispensing position of the metering and dispensing device, uncovers a discharge opening, from which the metered detergent is fed gradually to the treatment vessel. Sealing elements which surround the treatment vessel-side opening of the second chamber are provided, which cooperate with the lid.

A heating home appliance, in particular a household appliance such as an oven, includes an appliance space having at least one heating body. At least one multi-ply layer of air-tight foils at least partly surrounds the appliance space, enclosing air chambers, being at least peripherally joined together and otherwise being kept mutually spaced apart from one another. The at least one foil layer has foil edges, with an air-tight-sealed edge on all sides being formed of the foil edges and forming a flexible fastening and/or connecting element.

An oven door of a kitchen stove includes an inner door bottom, an outer door unit having additional door elements and a front panel being formed of glass or glass-like material and forming a door front. Connecting elements act as carriers for the additional door elements. The connecting elements are secured directly or indirectly to the front panel and are connected to the door bottom through contact points of low capacity for heat exchange, for joining the front panel to the door bottom.

A drive mechanism for a household washer-dryer includes an at least approximately horizontally rotatably supported tub having a tub jacket and a tub axis. A gear pinion has a drive belt being wrapped around the tub jacket for driving the tub in opposite directions. A large pulley is connected to the gear pinion, is fixed against rotation relative to the gear pinion and is supported on a common axis with the gear pinion. An electric drive motor has a motor pinion with an axis. A gear belt is driven by the motor pinion for driving the large pulley. The common axis is movably guided axially parallel and is spring-loaded in a direction toward an increase in spacings between the common axis and the axis of the motor pinion as well as between the common axis and the tub axis.

A washing machine includes a perforated washing drum with a contact rpm at which items of laundry in the washing drum come to rest against a surface of the washing drum due to centrifugal force. The washing drum is intermittently driven in alternating rotary directions (reversing mode) during washing and/or rinsing, for accelerating the washing drum in one of the rotary directions to a first rpm being markedly below the contact rpm and accelerating the washing drum in the other of the rotary directions to a second rpm being markedly above the contact rpm.

A clothes dryer includes a housing, a back wall being joined to the housing, an at least approximately horizontally rotatably supported laundry drum having at least one bottom, and a bearing journal supporting the at least one bottom on the back wall. The bearing journal has a spherical bearing-relevant surface being secured to the back wall. The drum bottom has at least one bearing shell tightly embracing the spherical surface.

A piston system is used as a pressure-independent flow-volume-regulating valve in which the piston divides the piston chamber into two sections which communicate with one another via a flow-throttling zone and, dependent upon pressures applied which are opposed on the piston by restoring forces, affects control orifices. The restoring force for the piston is guided over a compensating member for temperature-dependent expansions.
