Abstract

The invention presents a system to control vibrations induced by poor distribution of the laundry in a washing machine during the centrifugation phase, based on the measurement of timing and intensity of the said forces by means of an accelerometer, and of the consequent generation of two counteracting rotating forces by means of the masses of water contained in suitable pockets (1), open at the inner radius (3) and located on the outside of the drum (5), or watertight and located on the inner edge of the drum, which are filled before centrifugation, and partially drained in a controlled fashion once the actual imbalance has been determined. The system features electronically controlled valve systems which can regulate both the uniform filling phase (where included) and the controlled drainage phase.
