Abstract
Method for drying laundry and a machine able to implement such a method, which provides for the use of only one electric resistance for heating the air utilized for drying purposes. According to the invention, during the starting phase of the drying process, i.e. the initial stage of the air heating, said resistance is applied continuously for exploiting its maximum power and quickly reach a predetermined temperature of the drying air. Following the attainment of said predetermined temperature, a special control circuit causes said resistance to be applied in a shuttered or modulated way, i.e. by alternating application phases to non-application phases within repetitive reference periods, in order to manage the power of the resistance in its steady-state condition for obtaining a substantial constancy of the air temperature.
