Abstract:
1. A process for an accelerated wetting of laundry in a speed-controlled drum of a program-controlled drum washing machine with a tub wherein said drum is rotatably disposed, with a measuring mechanism to determine a quantity of the laundry filled into the drum and with a controllable water filling device and a measuring device to determine a volume of incoming tap water (q) and for a level of the washing liquid in the tub formed of water and other substances, as well as with a control unit to affect the course of the movements of the loaded drum, the process comprising the following acts: performing a first phase (A) in which a stipulated volume of water to be filled into the tub is determined, the determination of the stipulated volume of water to be filled into the tub including characterizing an absorption capacity of the laundry by evaluating a ratio between the volume of incoming tap water (q) and the level of the washing liquid in the tub and thereafter stipulating the stipulated volume of water to be filled into the tub as a function of the absorption capacity of the laundry; performing a second phase (B) in which the drum is moved for a first defined time period in a manner by which the even soaking of the laundry item is achieved after reaching the stipulated volume of water to be filled into the tub; performing a final phase (C) during which the drum is at least one of stopped and powered in a direction for a second defined time period required at a first defined speed suitable to soak the laundry during the final phase (C), and the washing liquid required for the subsequent washing phase (D) is only defined and filled up after the end of the second defined time period; and performing a washing phase (D) in which the drum is powered at a second defined speed suitable for washing in intervals and reversing of direction.
