Method for providing active damping of the vibrations generated by the washing assembly of washing machines and washing machine implementing said method

摘要

A shock absorber damps the vibrations that are generated in a washing assembly of a horizontal axis washer. The shock absorber is of the type containing a magnetorheological fluid. A method carried out in a real-time mode throughout the duration of the operation cycles of the machine varies at least one of the rheological properties of the medium and, in due proportion, the vibration damping power of the shock absorber. The method is based on the monitoring of a physical quantity that is representative of the variations in the balance conditions of the washing assembly. The invention provides effective and immediate damping of the vibrations caused by an unbalanced washload in the rotating drum, without any interruption or modification of the washing cycle selected and set by the user.
