Device for detecting values for rotational speed and/or imbalance and/or downtime position of washer drum in water container of household washing machine, has evaluation device for detecting pressure and/or distance of body on ring

摘要

The device has a washer drum (3) comprising a centrifugal force body (9) at a spatial proximity to outer circumference of a drum casing (8). The body is movably and elastically held in a position in a radial direction, and a fixedly standing ring (12) is arranged at a determined distance to the drum. The ring has an evaluation device (14) for detecting pressure and/or distance of the body on the ring. The ring has an inelastic support, an energy-elastic protection layer and a piezoelectric measuring strip, where the body has a magnetic or electrically-conducting base part.
