Definitions

  • the present invention generally relates to a device with which an imbalance of a rotatable component of a household appliance, such. B. a drum of a washing machine or a tumble dryer, can be detected.
  • Household appliances may have rotatable components, in the rotation of which it may lead to undesirable, non-uniform movements, in particular in the form of imbalances. This applies in particular to rotatable components of household appliances, which serve to rotate objects for the treatment of which the respective household appliance is provided. Examples of such rotatable components are drums of washing machines and tumble dryers and rotary devices (e.g., turntables) in microwave ovens and kitchen stoves.
  • Unwanted movements due to unbalance rotatable components can occur especially when the mass of unevenly distributed in or with rotatable components to be rotated or rotated objects.
  • a particularly illustrative example of this is an uneven distribution of laundry in a drum of a washing machine, which can lead to imbalances and resulting unwanted movements of the drum, in particular at high rotational speeds of the drum (for example when spinning).
  • the DE 199 20 870 A1 describes a washing machine that allows a measurement of the laundry weight. For this purpose, a pressure dependent on the weight of the laundry is measured and converted into a weight.
  • the DE 100 07 839 A1 describes a vibration detecting device with a coil whose core is movable due to vibrations, thereby changing the inductance of the coil.
  • Object of the present invention is to detect movements caused by imbalance of a rotatable component of a household appliance more accurately and easily.
  • the present invention provides a device for detecting imbalance caused movements of a rotatable component of a household appliance, a household appliance comprising such a device according to the independent claims.

  • the spring arrangement and / or the mass and / or the damping is designed so that above a predetermined frequency of movements of the rotatable component, which are caused by their imbalance, movements of the mass from the initial position are substantially independent of frequency or frequency-dependent components of such Movements of the mass lie in a predetermined range, ie do not exceed a certain size.
  • movements of the rotatable component which are associated with their unbalance, can be detected precisely, in particular because in the device according to the invention caused by resonance movements of the mass, if they occur at all, in a range of unbalanced movements of the rotatable Component can be set, which can be classified as uncritical for the operation of the household appliance or rotations of the rotatable component or which is of little or no interest.
  • the device according to the invention allows, for example, movements caused by resonance to shift the mass into a frequency range of movements caused by imbalance of the rotatable component, which corresponds to low rotational speeds.
  • Movements of the rotatable component caused by their imbalance and below the predetermined frequency may be determined using other unbalance determination devices, such as speed-dependent approaches. Additionally or alternatively, this can be achieved by one or more further devices according to the invention with a smaller predetermined frequency.
