Definitions

  • the invention relates to a drive device for a washing machine which can be loaded from the front and has a washing drum which is mounted on the inside of a bearing sleeve of a rigid supporting part which is attached to the rear wall of a tub, via an at least approximately horizontally lying shaft and which is also mounted on the back of the tub by a flat motor is directly driven.
  • Such drive devices are known from DE 39 27 426 A1 and DE 43 41 832 A1.
  • the stator of the motor designed as a brushless external rotor direct current motor is fastened directly on the bearing sleeve of the rigid support part.
  • the shaft is mounted in the bearing sleeve and is connected at its outer end to the rotor of the motor in a rotationally fixed manner.
  • This rotor is a so-called external rotor, which overlaps the stator windings as a pot and carries poles designed as permanent magnets.
  • the motor is additionally surrounded by an insulation hood, which dampens noise emitted by the motor directly to the surrounding atmosphere.
  • the known drive devices encapsulate the stator, which is exposed to a considerable temperature load due to current heat in its windings, by a pot-shaped rotor (in the case of DE 43 41 832 A1 additionally by the sound insulation hood) so strongly that cooling of the motor fails at all. This is supported above all by the fact that such a directly driving motor can hardly be cooled by the rotating rotor because of its necessarily low inherent speeds. Therefore, the known drive devices are practically only useful if they are protected from rapid overheating by external cooling.
  • the known drive devices are also not available as a fully assembled motor to the manufacturer of washing machines. Your stand and runner must be separate delivered and assembled in the washing machine factory. Since special assembly devices for completing motor assemblies are generally not available in a washing machine plant and are also not desired, the stator assembly to be initially connected to the tub system should only be inaccurately completed by the external rotor assembly. Since extremely high demands are made on maintaining a small air gap between the stator and rotor poles, as large as possible for each specimen, as well as on the centered storage, which cannot be met in the aforementioned assembly in a washing machine factory, the known ones Drive devices can only be used to a very limited extent in practice.
  • the invention has for its object to design the drive device mentioned above so that on the one hand cooling of the stator windings through the ambient air can be easily guaranteed and the motor can not overheat in proper operation with dimensioning according to requirements and on the other hand the motor is completed in the factory of the motor manufacturer and can be checked before it is to be installed at a washing machine manufacturer.
  • the stand is connected to the rigid support part or instead of the rigid support part with the rear wall of the tub and has a central bearing sleeve for the shaft of the laundry drum and for a hub of the rotor encompassing the shaft, that at the outer end the shaft, the hub of the rotor, which has a plurality of openings between its hub and the peripheral part and on its periphery a bell-shaped flange facing the tub, is centered and that the rotor with its magnetizable poles distributed on the inner periphery of the bell-shaped flange via a minimal air gap is opposed to the sheet metal packages distributed on the stand intended to accommodate exciter windings of the stand from the outside.
  • the configuration according to the invention gives the motor an open design, the heat-generating components of which, above all the stator windings, can be cooled from all sides by the ambient air. Even the low engine speed during washing operation is then sufficient for the rotor to generate heat-dissipating air movement.
  • the engine can also be fully assembled and tested in the engine supplier's factory.
  • the appropriate assembly and testing aids are available there, so that precisely assembled motor assemblies can always be delivered to the washing machine factory.
  • this assembly can be mounted on the rear wall of the tub system instead of a cast support star otherwise usual at this point or in addition.
  • the stator of the complete motor is attached to the rear wall of the tub by means of several screws. Then the shaft of the laundry drum from inserted into the hub of the rotor, which is already connected to the stand via the roller bearings, and secured from behind with a central screw.
  • parts of the rotor are designed to support an air movement which arises during its rotational movement, the rotor can be operated even with a slight rotational movement, e.g. at washing speed, produce enough cooling air for the stator windings.
  • a slight rotational movement e.g. at washing speed
  • the motor is an electronically commutated direct current motor
  • the heat development can moreover be kept extremely low. Maintenance is not necessary (no carbon brushes). The service life is only limited by possible bearing wear.
  • the rotor is at least partially equipped with an annular package of dynamo sheets and permanent magnet segments arranged thereon.
  • the permanent magnet segments produce a powerful torque, and the dynamo plates form a particularly good magnetic reflux.
  • the automation of the stacking process makes the production of the required laminated cores relatively uncomplicated and inexpensive.
  • the pole packs of the stator are advantageously composed of dynamo sheets and carry coils with the excitation windings.
  • the centered connection of the rotor can be supplemented in a rotationally fixed manner on the shaft by a positive profile shaft, profile hub, feather key, cone or keyway connection.
  • the motor can be designed as a so-called switched reluctance motor.
  • the rotor consists of a ferromagnetic material that is relatively poorly conductive.
  • the structure of the stator is comparable to that of the electronically commutated DC motor.
  • the advantage is in particular a more cost-effective design of the rotor (no expensive magnetic materials).
  • the tub 1 is swingingly mounted in a housing of a washing machine, also not shown, in a manner not shown here.
  • a motor 9 is mounted on the rear wall 6 of the tub 1, the stand supporting part 10 of which is connected to the rear wall 6 in a rotationally fixed manner via the flange 11.
  • a plurality of stator windings 12 are distributed on the rear surface of the stator support part 10 and, during the rotation of the rotor 13, alternately correspond to its poles 14, which here consist of permanent magnets and are also distributed in segments on the circumference of the rotor 13.
  • the magnetic return flow of the magnet segments 14 is formed by a packet of dynamo sheets 16 inserted into the bell flange 15.
  • the motor can introduce its drive torques directly into the washing drum 4 via the shaft journal 7.
  • the stator 10 of the motor like a supporting star replaced by it, also absorbs all bearing forces.
  • the rear wall 8 of the laundry drum 4 is stiffened with a support star 17, the hub 18 of which is connected in a rotationally fixed manner to a shaft journal 7.
  • the stand supporting part 10 carries on its outer circumference a plurality, preferably three, of fastening eyes 23 which are distributed around the circumference of the tub 1 and which provide a fixed connection to the tub by screws 24 via tabs 25 welded to the tub 1.
  • the stand support part 10 is screwed to a mounting disk 20 (screws 19), which in turn is screwed to the tub 1 on the rear wall 6 (screws 24).
  • the stand supporting part 10 can be made in one piece together with the mounting disk 20. Then the separate screwing of the bearing part 21 for the stator poles (consisting of windings 12 and laminated cores 32) to the mounting disc 20 would be omitted.
  • the bearing sleeve 22 of the stand supporting part 10 forms bearing seats 26 and 27 for rolling bearings 28 and 29, the inner rings of which are fitted onto the shaft journal 7 of the washing drum 4 with a good fit are.
  • the shaft 7 is inserted into the hub 31 of the rotor 13 and secured by means of a central screw 30, so that it connects the rotor 13 to the laundry drum 4 in a rotationally fixed manner via its hub 31 and the inner rings of the roller bearings 28 and 29.
  • the rotor disk 13 is equipped with openings 33 for better ventilation and cooling of the stator poles between its hub 22 and the bell flange 15 serving as a support ring for the magnetic segments 14.
  • These openings can advantageously be shaped at their edges so that the access of cooling air through these openings is supported in the sense of a fan effect.
  • so-called whirlers can be attached to the openings or in the vicinity thereof, which swirl the cooling air so that it receives better contact with the stator windings.
  • the motor is designed here as an electronically commutated DC motor. However, it can also be designed as a so-called switched reluctance motor.
  • at least the flange of the rotor or its inner support consists of a ferromagnetic material that is relatively poorly conductive.
  • the structure of the stator is comparable to that of an electronically commutated DC motor.
  • the advantage of the reluctance motor is, in particular, a more cost-effective design of the rotor (no expensive magnetic materials).
  • the screw connection 30 of the rotor 13 on the shaft 7 can be positively supplemented by a profile shaft, profile hub, feather key, cone or keyway connection, not shown.
