Abstract: An appliance for drying laundry has an appliance housing, at least one open drying air duct situated inside the appliance housing, for sucking in ambient air during a drying process, and at least one heat pump, which is situated inside the appliance housing and is thermally coupled to the drying air duct. To reduce the energy consumption of such an appliance, the drying air duct has at least one air intake opening, which is situated inside the appliance housing and is situated in a section of the drying air duct upstream of a condenser of the heat pump in relation to an air mass flow through the drying air duct prevailing during the drying process.

Abstract: An appliance for drying laundry contains an open process air system having a drying chamber for receiving laundry to be dried, and a heat pump that is thermally coupled to the process air system. The heat pump has an evaporator serving as a heat sink for process air discharged from the drying chamber, and a condenser serving as a heat source for the process air to be supplied to the drying chamber. In order to improve a heat transfer between the process air system and the heat pump, and to minimize pressure losses within the process air system, the evaporator and the condenser are arranged laterally side-by-side and offset in height with respect to each other. One portion of a first process air duct extends above/below the condenser, and one portion of a second process air duct extends below/above the evaporator.

Abstract: The invention relates to a water-circulating household appliance that may be, for example a washing machine, washer-drier, or clothes drier. The household appliance includes a rotatably mounted washing drum with a drum casing and a drum cover face. The washing drum is embossed with protrusions in the form of embossments whose edges are ellipsoidal.

Abstract: A drive device for a household appliance, in which an electromotor is fixed by a fixing screw. An insulation layer of a material with a defined conductivity is located between the fixing screw and the electromotor. The fixing screw is tightened with a defined torque such that, due to the resultant defined contact pressure, a defined resistance for discharging electrostatic charges from the electromotor is obtained. This simultaneously ensures the suppression of leakage currents. A method for mounting an electric motor is also disclosed.

Abstract: A washing machine includes a washing tub having a plastic injection-molded rear wall with a shaft mounted in the rear wall. An at least substantially horizontally mounted laundry drum is connected to the shaft in a rotationally fixed manner. A drive mechanism is connected to the drum for driving the drum, the drive mechanism has a stator support part. The rear wall is plastic injected molded around the stator support part for rotationally fixing the stator support part to the rear wall of the tub.

Abstract: A drive apparatus for a washing machine having a laundry drum and a suds container includes a stiff supporting star having a bearing sleeve for mounting the laundry drum of the washing machine in the bearing sleeve, a substantially horizontal shaft for connecting the supporting star to the rear wall of the suds container, a flat motor for directly driving the laundry drum, and a bearing. The motor is to be mounted on the rear wall of the suds container. The motor is connected to the supporting star and has a stator support, field windings connected to the stator support, a rotor connected to the shaft through a bearing of the shaft, and magnetic poles connected to the rotor. The bearing connects the stator support to the rotor.

Abstract: A compact drive apparatus for a front-loading laundry treatment machine includes a support having a projection and a rear face, a shaft having an axis, a laundry drum having a rear wall, and a motor having magnetic poles and a stator with field windings and laminated cores. The laundry drum is mounted substantially horizontally on the support through the shaft. The rear wall has a bell-shaped depression with an inner circumference. The depression extends in a direction of the longitudinal axis and accommodates the projection. The motor is disposed on the rear face and directly drives the shaft. The laminated cores are disposed on the projection, and the magnetic poles are distributed on the inner circumference and are disposed externally opposite the laminated cores to accommodate the field windings with an air gap therebetween. Preferably, the projection is a bell-shaped flange of the support or of the rear wall of the support to surround the shaft as a bearing sleeve.

Abstract: A front-loading washing machine includes a tub having a rear wall with an inside surface, an outside surface, and a center, a bearing sleeve connected to the rear wall, a shaft disposed in the bearing sleeve and at the center of the rear wall, a motor connected to the outside surface of the rear wall at a distance from the center of the rear wall, a gear mechanism connected to the shaft and to the motor, and a laundry container mounted in a floating manner to the bearing sleeve through the shaft. The motor produces a torque and the gear mechanism transmits the torque produced by the motor to the shaft. The motor drives the laundry container. If the laundry container has a filling opening inclined upward, then the motor is disposed beneath the shaft in a region between the tub rear wall and a rear wall of the washing machine.

The hollow shaft of the rotor surrounds the journal. The stator and rotor are jointly connected to the journal. Instead of the support, the rear wall can be reinforced to include the bearings therein.

Abstract: A front-loading washing machine includes a rotatable laundry basket. The basket's lowest casing line deviates from horizontal by sloping upward toward the front when the machine is in an operating position. The basket has hollow longitudinally extended carriers disposed on the inside surface of the casing and including liquid inlets in the basket's rear area. The inlets are loaded with liquid when the basket rotates into a lowest position and direct the liquid into the carriers, which lift the liquid therein and deliver it from a lifted position into the basket's interior through openings. The basket remains easy to manufacture while ensures both rapid wetting of the laundry and at least equally good washing action. The laundry basket is mounted cylindrically around a rotational axis that slopes upward toward the front, and the carriers are slantingly disposed with regard to the basket rotation direction.
