Abstract (en)

[origin: WO03010380A1] The inventive washing machine has a drum, which turns inside a fixed lye tub and which has an inclined rotation axis that slopes toward the loading opening and is provided with scooping devices, which are mounted on the drum, scoop the lye, and whose scooping performance is dependent on the direction of rotation of the drum. In a preferred direction of rotation, scooping direction, the scooping devices uniformly wet the articles to be washed with the lye. During the wet treatment phase, the drum is operated in alternating directions of rotation and with a rotational speed that changes according to the direction of rotation for a respectively limited duration that can be varied in both directions of rotation. According to the invention, the drum is operated during the entire wet treatment phase in the scooping direction in time intervals IN, IW, IS, which are of approximately equal length and characterized by a uniform specified rotational speed of the drum. In addition, the rotational speed and the duration of the time intervals INg, IWg, ISg vary in the direction counter to that of the scooping according to the progress of the wet treatment phase. In a first phase, wetting phase N, the rotational speed of the drum nN in the scooping direction is less than the washing rotational speed nW, and the duration of the time interval INg in the direction counter to that of the scooping is significantly shorter than in the scooping direction. In a second phase, washing phase W, the rotational speeds nW and -nW of the drum are the same as in the wetting phase, the duration of the time interval IWg in the direction counter to that of the scooping is, however, extended in comparison to the wetting phase N. In a third phase, rinsing phase S, the rotational speed nN of the drum in the scooping direction, is equal to that in the wetting and washing phase but, in the direction counter to that of the scooping (-nS), is significantly greater than an application rotational speed in which the laundry rests against the drum surface, and the duration of the time interval ISg in the direction counter to that of the scooping is significantly shorter than in the washing phase W.
