Abstract
A method for achieving load balance in washing machines provided with a rotary drum driven by an electric motor under the control of control means, and in which a circuit is provided for measuring a physical quantity associated with information relative to the state (balanced or unbalanced) of the load in the drum, the method comprising, after the wash stage, a stage in which the drum speed is gradually increased during which the physical quantity is continuously monitored to ascertain the state of load distribution within the drum, and a stage of rapid rotational speed increase at the moment in which a state of balanced load distribution within the drum is detected.
