Abstract (en)
A clothes washing machine provided with a washing tub, a drum adapted to rotate inside said tub and to hold the washload, a motor capable of driving said drum at a number of variable rotating speeds, and an arrangement adapted to detect an unbalance condition of the washload, is adapted to perform a spin-extraction phase comprising a sequence (T1-T2) of drum revolutions under low-speed (CBV) spinning conditions so as to favour a balanced distribution of the washload in the drum, wherein after such a distribution of the washlaod within a predetermined balancing level a second spin-extraction phase (T2-T4) is started at an intermediate spinning speed (CMV) for a very short period of time. After this second spinning phase, the speed of rotation of the drum is reduced to the low-speed (CBV) spinning value so as to keep the distributed washload adhering against the walls of the drum. Thereupon, the drum RPM is again increased up to said intermediate spinning speed (CMV), which is then maintained for a given period of time (T5-T6). <IMAGE>
