Definitions

  • the usual laundry treatment processes in a washing machine consist of several treatment steps (wetting phase, prewash, main wash, rinsing), which are each associated with a more or less complete exchange of the aqueous liquid in the tub.
  • Each laundry treatment step generally begins with the supply of fresh water, which is disposed of as waste water at the end of the respective treatment step.
  • treatment agent residues e.g. detergent, fabric softener
  • rinsing-spin cycles are switched in which the drum is rotated at a high speed. A lot of electrical energy is required for this.
  • Water consumption is an important factor in the operation of a washing machine. For economic and ecological reasons, it is desirable to keep the water consumption as low as possible, with a minimum consumption of water being specified due to the mechanical engineering conditions and the suction behavior of the laundry items to be treated.
  • the actual washing phase is generally followed by a rinsing phase with one or more rinsing steps with water using suitable detergents.
  • the laundry items are freed of the washing liquor enriched with impurities and detergent and any residues of detergent and detergent still adhering to the laundry items.
  • the traces of such substances remaining on the fibers of the laundry items after the rinsing phase are smaller, the more water is used in the rinsing and / or the more frequently the water is rinsed.
  • the time and amount of water used for rinsing should, however, be reduced due to the demands of users of washing machines and with regard to the generally desirable economical use of water while maintaining high rinsing efficiency.
  • washing programs are being developed with a view to a larger load ratio, lower energy consumption, lower water consumption, shorter washing programs and a better residual moisture content.
  • the EP 2 540 896 A1 describes a method for washing laundry in a washing machine with a rotatable drum located in a tub, comprising the steps of providing an amount of detergent, a first amount of water to provide a certain amount of a wash liquor therefrom; Introduction of the wash liquor into the tub; Recirculating the wash solution within the tub until this wash liquor is absorbed by the laundry items within the drum and the level of the wash liquor is below the drum; Activating a heating means to heat the moistened laundry inside the drum; Switching off the heating medium and holding the heated and moistened items of laundry for a certain drying time ( "predetermined dry maintenance time” ); Adding a second amount of water to the tub; Rotate the drum and rinse the laundry items by rotating the drum and removing the liquid from the tub.
  • the starting point of the invention is the improvement of the wetting phase.
  • washing machine refers to both a pure washing machine that has only one washing function and to washing dryers that are a combination between a washing machine and a dryer.
  • addition means the addition to the tub and / or the drum. Since these are generally connected to one another by openings in the drum jacket, water and detergent will mix, the concentration of the detergent generally being the same in the tub and in the drum.
  • treatment step also includes one here Treatment step with a fabric softener, colorant or other chemical treatment agent.
  • the treatment steps according to the invention are washing steps and the treatment agent is a detergent.
  • steps (a) to (c) are carried out can be different. There may also be a temporal overlap of steps (a) to (d). However, step (a) is preferably carried out first and then steps (b) and (c) are carried out simultaneously or in succession, the sequence of steps (b) and (c) being different. In general, however, a detergent is added together with the water, for example via a washing machine dispenser.
  • the treatment liquor is partially removed from the tub and water is added, and the items of laundry are each washed with a reduced concentration C n + 1 ⁇ c n (n ⁇ 1) of detergent in a (n + 1) -th treatment step treated.
  • the amount of treatment liquor removed and the amount of water added can each be the same or different, independently of one another. In particular, the amount of water added can also be greater than the amount of treatment liquor removed.

  • aqueous liquid as used herein means in particular water and treatment liquor.
  • a washing machine used for the method according to the invention generally has a drain pump, the treatment liquor is generally removed by pumping.
