Definitions

  • the invention relates to a washing machine with a housing of the type specified in the preamble of claim 1.
  • the spin speeds should be between 1300 and 2000 1 / min, while for the noise level the maximum is aimed for washing LWA 47dB and for spinning LWA 49dB.
  • the invention has for its object to provide an automatic washing machine, in particular for the luxury class, with which all desired speeds of 25 to 2000 1 / min can be generated for the spin cycle and for the different washing cycles without unfavorable consequences. Furthermore, a largely uniform washing and spinning effect should be kept as constant as possible Speeds and low noise level can be achieved. This object is achieved by the features characterized in claim 1.
  • the washing drum is driven directly by a multi-pole motor, the requirement of the speed limitation, in which the maximum motor speed is identical to the desired high spin speed, can be met.
  • the desired low noise level is achieved in that the drive motor is encapsulated by an insulation hood.
  • the back wall of the tub can also be provided with noise insulation. Since the drive motor has no brushes and is advantageously designed as a synchronous motor with a converter, the encapsulation of the motor can be carried out without concern for thermal reasons. This is also favored because the electronics are not arranged on the motor.
  • An automatic washing machine 1 has a housing 3 in which a mechanically vibrating unit 5 is arranged, which consists of a horizontally lying washing drum 7, a tub 9 surrounding it and a drive motor 11 driving the washing drum 7 directly.
  • a mechanically vibrating unit 5 which consists of a horizontally lying washing drum 7, a tub 9 surrounding it and a drive motor 11 driving the washing drum 7 directly.
  • the other parts necessary to control the washing machine 1 are not shown in detail.
  • the drive motor 11 is arranged as a brushless motor on the outside 22 of the tub rear wall 15 and surrounded by an insulation hood 13, through which the motor noises are effectively shielded.
  • the insulation hood 13 is firmly connected to the rear wall 15 of the tub 9. Since the control electronics 16 are not on the drive motor 11, but on one remote from it Place in the housing 3, for. B. is arranged in the region of the front wall 18, the encapsulation of the drive motor 11 can be carried out without hesitation, especially since the drive motor 11 also has no brushes.
  • the drive motor 11 is an external rotor motor, the permanent-magnet rotor designed as an external rotor 23 directly drives the drive shaft 24 of the laundry drum 7.
  • the drive shaft 24 is in this case rotatably mounted on one side in a bearing consisting of two roller bearings 26, 27 in an outwardly projecting hub 28 on the tub rear wall 15.
  • the stator 29 with the stator laminated core 30 is arranged annularly to the hub 28.
  • the drive motor 11 can either be a synchronous motor with a converter or a reluctance motor.
  • the insulating hood 13 surrounding the drive motor 11 consists of a hollow cylinder 21 closed on one side by a base 20, which closely surrounds the outer rotor 23 and whose opening edge 25 is firmly connected to the tub rear wall 15.
  • the washing machine 1 according to the invention can be operated at engine operating speeds of 25 to 2000 1 / min, the desired noise level being achieved simply and effectively by encapsulating the noise of the drive motor 11.
