ON-OFF DAMPER SYSTEM, ESPECIALLY FOR WASHING MACHINE

摘要

The invention provides a rotating tub washer with an on-off binary damper system for damping a problematic movement between the washer frame and the rotating tub. The on-off binary damper system has a friction pad (26) and a housing friction damper surface (28), with the friction pad (26) in contact with said housing friction damper surface (28). The on-off binary damper system has an electromagnetic coil core (30) and a magnetic locking slide (32) with a slide gap (34) between said electromagnetic coil core and said magnetic locking slide to provide for relative sliding motion between the electromagnetic coil core and the magnetic locking slide, wherein a current supplied to said electromagnetic coil core removes the slide gap and electromagnetically locks the electromagnetic coil core and the magnetic locking slide together with the relative sliding motion transferred to the friction pad, with the friction pad rubbing against said housing friction damper surface inorder to dampen the problematic movement between the frame and the rotating tub.
