Abstract:
1. A method for controlling the processing of laundry in a laundry processing device, the device comprising a drum, adapted to accommodate laundry and being rotatably mounted on a support so as to be rotated about a substantially horizontal axis; a motor, arranged for rotating the drum, and a controller, configured to control the rotary speed of the drum, the method comprising initiating, when the drum contains laundry, a rotation of the drum by means of the motor; recording and storing, while the laundry is being processed, a signal that is correlated to the interaction between the drum and the laundry, and that exhibits a variation caused by the rotation of the drum; determining a speed that yields the maximum tolerated level of mechanical action on the laundry in a wool or delicate fabrics laundry processing program; selecting a level of mechanical action on the laundry below a maximum tolerated level of mechanical action on the laundry in the wool or delicate fabrics laundry processing program; determining a target rotary speed of the drum based on the signal correlated to the interaction between the drum and the laundry and based on the selected level of mechanical action on the laundry by keeping the target rotary speed below the speed that yields the maximum tolerated level of mechanical action on the laundry in the wool or delicate fabrics laundry processing program; and adjusting the rotary speed of the drum to the target rotary speed, wherein the signal that is correlated to the interaction between the drum and the laundry is determined on the basis of impact acceleration of the drum or of any structure connected to the drum as the laundry hits the bottom inner surface of the drum or the force exerted by the drum on any structure supporting the drum.
