Definitions

  • the invention relates to a washing machine with a housing specified in the preamble of claim 1.
  • the spin speeds should be values of 1300 to 2000 1 / min, while for the noise level at most for washing LWA 47dB and for spinning LWA 49dB be aimed for.
  • Document FR-A1 345 648 describes a fully automatic washing machine with one on the outside of the tub back wall Drive motor that drives the washing drum directly and that is surrounded by a hood.
  • the hood fulfills one Protective function.
  • the invention has for its object a To create washing machines, especially for the luxury class, with which all desired speeds from 25 to 2000 1 / min for the spin cycle and for the different Have washing cycles produced without any unfavorable consequences. Farther is said to be a largely uniform washing and Spin effect with constant as possible Speeds and low noise level can be achieved. This object is characterized by those in claim 1 Features resolved.
  • the washing drum is driven directly by a multi-pole motor is, the requirement of the speed limit at which the maximum engine speed with the desired high spin speed is identical, be met.
  • the targeted low Noise level is achieved in that the drive motor from is encapsulated in an insulation hood. In addition, then also soundproof the back wall of the tub become. Since the drive motor has no brushes and is more advantageous Formed as a synchronous motor with a converter is encapsulating the motor for thermal reasons be done without hesitation. This also becomes favored, since the electronics are not arranged on the motor.
  • the invention is based on the embodiment shown in the figure described in more detail.
  • a washing machine 1 has a housing 3 in which a mechanical vibrating unit 5 is arranged, which consists of a horizontal lying laundry drum 7, a tub 9 surrounding it and a drive motor 11 directly driving the washing drum 7 consists. The others necessary to control the washing machine 1 Parts are not shown in detail.
  • the drive motor 11 is a brushless motor on the outside 22 of the tub rear wall 15 and arranged by an insulation hood 13 surrounded by which the engine noise effectively shielded become.
  • the insulation hood 13 with the rear wall 15 of the Vats 9 firmly connected. Since the control electronics 16 are not on the drive motor 11, but at a distance from it Place in the housing 3, for. B. arranged in the region of the front wall 18 is the encapsulation of the drive motor 11 without hesitation be made, especially since the drive motor 11 also none Has brushes.
  • the drive motor 11 is an external rotor motor, which is designed as an external rotor 23 permanent magnetic rotor drives the laundry drum 24 7 drives directly.
  • the drive shaft 24 is in one consisting of two roller bearings 26, 27 in one bearing externally projecting hub 28 on one side of the tub rear wall 15 rotatably mounted.
  • the stator 29 with the stator laminated core 30 is here arranged in a ring to the hub 28.
  • the drive motor 11 can either a synchronous motor with a converter or a Reluctance motor.
  • the insulation hood surrounding the drive motor 11 13 consists of a closed on one side by a bottom 20 Hollow cylinder 21 which closely surrounds the outer rotor 23 and its opening edge 25 is firmly connected to the tub rear wall 15.
  • the washing machine 1 can operate at engine operating speeds operated from 25 to 2000 1 / min, whereby by the Noise encapsulation of the drive motor 11 also the desired noise level is achieved simply and effectively.
