Definitions

  • the invention relates to a damper, in particular for washing machines with a spin cycle.
  • DE 22 04 325 C2 discloses a drum-type washing machine with struts or friction dampers for damping the vibrations of the washing unit. These each have a housing with a plunger slidably guided therein. To determine the insertion depth of the plunger, the plunger is hollow with a permanent magnet. Arranged in front of the housing of the damper in the direction of extension of the tappet is an annular coil which surrounds the tappet and is capable of detecting the position of the permanent magnet in the annular coil.
  • the known device makes it possible to determine a specific predetermined critical insertion depth of the ram and to interrupt the spin cycle, for example, due to particularly strong vibrations. The result is therefore only digital. A disadvantage of this arrangement is that the position of the plunger cannot be determined continuously.
  • the coil arranged upstream of the housing makes the overall arrangement longer. Another disadvantage is that it is not possible to determine the payload of the washing unit, since, due to the high static friction between the friction lining and the housing, the insertion depth is not a measure of the payload.
  • the invention has for its object to provide a damper with a housing and a plunger slidably guided therein, in which the insertion depth of the plunger into the housing is as simple as possible can be determined and from this the insertion force acting on the ram can be determined.
  • the object is solved by the features of claim 1.
  • the essence of the invention is that a measuring element is connected to the housing and the plunger, the relative position of which is determined by electrical interaction, the plunger having an essentially frictionless idle stroke over part of the insertion depth. This enables e.g. B. to measure the weight of dry laundry and water at rest and / or to detect dynamic imbalances during operation.
