A clothes dryer which comprises a housing, a rotatable drum for receiving the clothes and a bearing for rotatably receiving the drum in the housing. In order to protect the bearing from overheating, a cooling air device for cooling the bearing is provided.

Clothes dryer

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.

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.

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.

Drive apparatus for a front-loading laundry treatment machine

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.

Front-loading washing machine

A drive apparatus in a washing machine having a suds container with a rear face and a laundry drum mounted within the suds container includes a flat electric motor for directly driving the laundry drum. The motor is mounted on the rear face and has a stiff support connected thereto, a first bearing, a rotor with a hollow shaft, and a stator connected to the support. The stator and rotor are connected to one another through the first bearing and are jointly removable. A shaft floatingly mounts the laundry drum within the suds container and is mounted within the support through a second bearing. The shaft has a shaft journal projecting out of the support. 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.

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.

Front-loadable washing machine having a rotatable laundry drum

A method and appliance for determining the angular position of a laundry drum and a power consumption of an electric motor driving the drum to derive therefrom a laundry weight in the drum includes directly driving the drum with the motor from a lower laundry position to a raised position where a laundry center of gravity is offset from a rotation axis to produce a loading weight from the driving current of the electric motor measured when the raised position is reached. Alternatively or additionally, the drum is turned until the controller detects a power consumption of the electric motor corresponding to a stored maximum current value to derive a weight of the laundry from a signal corresponding to the angular distance. The controller stores a predetermined, defined maximum current value and measures a power consumption of the electric motor.

Method for determining the loading weight of a laundry drum and a laundry-processing machine for carrying out the method

A washing machine includes a laundry drum mounted through an at least approximately horizontally disposed shaft within a bearing sleeve of a rigid star carrier attached to a bottom wall of a tub. A drive device for the washing machine can be mounted on the rear side of the tub. The drive device includes a flat or pancake motor having a stator carrying part with exciting windings and a rotor with magnetizable poles, for driving the laundry drum directly. The stator carrying part and the rotor of the motor are releasably connected to one another, with the stator carrying part in a position relative to the rotor corresponding to an operating position, for a duration of transport of the motor until a final mounting on the bottom wall of the tub. Therefore, the motor can be delivered, ready-preassembled and tested, to the factory manufacturing washing machines. The motor can be installed there in washing machines in a simplified way, without the need for further action on the washing machine when the motor is being installed, which could put at risk adherence to tolerances necessary for the motor to operate properly.

Drive device for a washing machine

A washing machine includes a tub having a bottom wall and a laundry drum having an at least approximately horizontally disposed shaft. A drive device for the washing machine includes a flat motor for directly driving the laundry drum shaft. The motor includes a rotor having a rotor shaft and a stator connected to the bottom wall of the tub instead of to a rigid carrying part with a bearing sleeve for the laundry drum shaft. The stator has a central bearing sleeve with one or two spaced-apart rolling bearings for the rotor shaft. The rotor shaft has an end facing the laundry drum with a concentric bore for receiving the laundry drum shaft. The bore reaches approximately into a plane of the drum-side rolling bearing. The rotor has a bell fastened to an outer end of the rotor shaft with an edge pointing toward the tub. Magnetizable poles are distributed on the inner periphery of the edge and across airgaps oppose a number of exciting windings distributed circularly on the stator. The drive for the horizontally mounted laundry drum has a cost-effective construction, the motor may be fully preassembled at the factory where it is manufactured and the stator may replace an otherwise conventional star carrier for the tub.

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.
