Abstract:
1. A method for controlling a spinning cycle of a washing machine with a detergent solution tub spring-mounted in a housing in which a drum is supported so that it can rotate around a substantially horizontal axis, with a variable speed-regulated drive which drives the drum, with a device for detecting a speed of the drum, a device for detecting a movement of the detergent solution tub which is caused by items of laundry unevenly distributed in the drum, with a program controller, which controls the spinning cycle including the speed of the drum and its cycle over time, the method comprising: accelerating the drum up to a first speed at which the laundry items essentially lie firmly against the wall of the drum; detecting, with at least one sensor of the device for detecting, a movement of the detergent solution tub in at least one direction for at least one predetermined period during the rotation of the drum at a speed that is equal to or greater than the first speed; detecting the speed of the drum and determining an amplitude of the movement for the recorded direction; determining further movement amplitudes for known or detected speeds during the predetermined period; determining a change in a ratio, the ratio being the movement amplitude over the speed of the drum; and controlling, with the program controller, a subsequent portion of the spinning cycle as a function of the change of the ratio.
