Abstract
A method for controlling the length of a cycle for drying clothes contained in the drum of a clothes dryer machine, comprising measuring the quantity of water released by the clothes within a predetermined time during their drying, a signal being provided for stopping the machine if the measurement obtained is less than a predetermined value. The method includes measuring the quantity of water released from the clothes during their drying and employs apparatus to generate signals based on this measurement, the signals being fed to a control unit which controls air circulation through the drum and heating of the circulated air, the control unit monitoring the measured water released quantity, and acting to terminate the drying cycle when the variation has a negative gradient and when the signals correspond to a measured water quantity which is constant with time.
