Abstract: A washing machine, such as a laundry washing machine, a washing/drying machine or the like, has a tub housing a drum into which the laundry to be washed is loaded. The machine is equipped with at least one tank for a washing agent, and at least one supply duct is afferent to the tank for delivering the washing agent into the tub. A hydraulic washing circuit floods and drains the tank for cleaning purpose. A tank cleaning method is also disclosed.

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.

Abstract: Method for drying laundry and a machine apt to implement such a method, which provide for the use of only one electric resistance (R3) 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 (R3) is supplied with continuity 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 (MC,RL,TR,ST) causes said resistance (R3) to be supplied in a shuttered or modulated way, i.e. by alternating supply phases to non-supply 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.
