Definitions

  • the invention relates to a washing machine with a drum driven by a motor.
  • the drive motor of the washing drum is repeatedly switched off or switched in the direction of rotation. So far, the washing drum and thus the drive motor of the washing machine have run down without braking in such switching operations.
  • complex mechanical braking devices are provided for braking the centrifugal drum.
  • the invention has for its object to provide a washing machine of the type described in such a way that when the drive motor is switched off or in the direction of rotation, the drum driven by it can be actively braked in a simple manner.
  • the object is achieved according to the invention in that when the motor is switched off or in the direction of rotation, a braking resistor is connected to the circuit of the stator winding of the motor.
  • the motor which continues to run after the driving voltage is switched off due to the rotating flywheel masses, acts after the switch-off as a generator which then works on the braking resistor. Due to the current flowing through the braking resistor in the stator winding, a counter torque is generated by which the motor is braked intensively.
  • the one or more heating rods in the device as a braking resistor
  • Heating device are connected to the stator winding, a separate resistance element is unnecessary.
  • a brushless DC motor is selected as the motor and the braking resistor is connected to the circuit of the stator winding via a rectifier element which is polarized opposite the driving voltage, a separate control device for switching on the braking resistor is not necessary.
  • page 1 A further increase in the moment of inertia and thus the recoverable energy is achieved in that the rotor of the motor is designed as an external rotor which has a cup-shaped support part, on the inner circumference of which the excitation magnets of the motor are arranged.
  • Such an external rotor has a correspondingly large diameter and thus a large moment of inertia.
  • Fig. 1 shows a schematic representation of the tub of a washing machine with a washing drum rotatably arranged in it and Fig. 2 is an electrical circuit diagram of a collectorless DC motor with a braking resistor connected to its stator winding.
  • washing drum 1 is usually installed in a corresponding housing of the washing machine. This housing is not shown in the drawing.
  • a washing drum 2 is rotatably mounted in the tub 1.
  • the washing drum 2 is provided with a direct drive, as in the
  • stator winding 3 of the collectorless DC motor is connected to a feed network 10 via a converter 9.
  • a braking resistor 11 is connected to the circuit of the stator winding 3 via a diode 12 which is opposite to the supply voltage in its forward direction.
  • the rotor 5 of the motor is braked accordingly.
  • the heating device of the washing device is used as the braking resistor 11, then the washing current can heat the items accordingly. This results in an energy saving.

Abstract

L'invention concerne un lave-linge comportant un tambour entraîné par un moteur. Pour obtenir, de façon simple, un ralentissement du moteur lors de l'arrêt ou du changement de sens de rotation de ce dernier, on monte une résistance de freinage (11) dans le circuit électrique de son enroulement de stator (3).
