Abstract (en)
[origin: WO2015082281A1] The invention relates to a method for operating a washing machine for treating laundry (7), having a drum (2) mounted in a rotatable manner in a tub (1), having a drive motor (14) for the drum (2), having a control device (12), having a water-supply system (8, 9, 10, 11), having a measuring device (18) for determining a quantity of aqueous liquid (6) introduced into the tub (1), having a heating device (13) for heating the aqueous liquid (6) in the tub (1), and having a temperature sensor (17), wherein the following steps are carried out: (a) introducing a first quantity q1 of aqueous liquid (6) at a temperature Tq1 into the tub (1); (b) heating the quantity q1 of aqueous liquid (6) to a predetermined temperature T 1 > Tq1; wherein the quantity q1 can be introduced in one dose or in a state in which it is divided into a number of sub-quantities q1', and the operation of heating to the temperature T1 can begin following the introduction of q1 or after one or more sub-quantities q1' have been added, wherein q1 and a first sub-quantity q1'' introduced are each greater than a quantity qmin, which is necessary for covering the heating device (13); (c) adding a second aqueous quantity q2 at a temperature Tq2 < T1 to the heated aqueous quantity q1; and (d) carrying out a washing phase with the laundry (7) in the presence of a detergent. The invention further relates to a washing machine suitable for implementing said method.
