Furthermore, the invention relates to a method for determining a fault condition of a vibration device of a household appliance for the care of laundry, in which a drum for receiving the laundry items is mounted in a housing of the household appliance by means of the oscillating device.

  • the determination of an error state can thus be carried out more accurately and even the slightest deviations of the oscillating device from a standard state can be detected.
  • the acceleration sensor is arranged on the drum. There, it can be positioned mechanically stable and since the drum is coupled to the oscillating device, it is therefore also possible to make a very precise statement about the state of the oscillating device via the position of the drum. Unwanted high loads of the acceleration sensor in a moving oscillating device can be avoided by this positioning. Since the springs and / or dampers of the oscillating device change length during operation due to their configuration, positioning the acceleration sensor on such a component is more difficult and can also lead to impairments of the acceleration sensor. By attaching to the drum these possibly occurring difficulties can be avoided.

  • the springs 6 and 7, which are only mentioned by way of example in number and position, are connected in an upper region of the housing 2 with this.
  • the dampers 8 and 9 which are also shown by way of example in number and position, are connected to the housing 2 at a lower area.
  • the oscillating device 5 comprises a drive motor, not shown, which may be, for example, a permanent magnet synchronous motor.

  • a state is shown, in which an error of the vibrating device 5 is present. It can be seen that the drum 3 is no longer centrally positioned centrally when the oscillating device 5 is at rest, but a certain inclination occurs. As a result, the direction 13 of the measuring axis 14 is no longer vertically downwards and no longer coinciding with the direction 12 of the gravitational acceleration. In Fig. 2, therefore, a deviation between the directions 13 and 12 has occurred, which characterizes a fault condition.
