Abstract (en)

A method of balancing the drum (6) of a washing machine (1) wherein the drum (6) is mounted to rotate about its longitudinal axis (A) and houses a variable amount of laundry; the drum (6) having a number of balance tanks (12) spaced angularly on the lateral wall of the drum; and the method including the steps of filling all the balance tanks (12) on the drum (6) with water; rotating the drum (6), and the laundry inside it, at a reference rotation speed (É 0 ) high enough to freeze distribution of the laundry on the lateral wall of the drum (6); determining an optimum distribution of the water in the balance tanks (12) to balance the effects of uneven distribution of the laundry on the lateral wall of the drum (6); and selectively draining surplus water from the individual balance tanks (12) to achieve the optimum distribution of the water in the balance tanks (12) and so balance the drum (6) rotating about its longitudinal axis (A).
