Washer-drier or drier with moisture scanner - has sensor inside laundry drum and scanning element is only in contact with slip ring when required

摘要

A washing machine and drier or a drier has a rotating drum and a moisture scanning device, which has at least one sensor inside the drum. The sensor is connected to an evaluator circuit via at least one slip ring and at least one stationary scanning component. The scanning element is brought into contact or outside contact with the slip ring via a mechanical setting means. ADVANTAGE - The invention reduces wear as the scanning element, pref. metal bristles, is brought into contact with the slip ring only when it is actually required.
