  • water is poured into the tub until it is partially filled to wet the laundry in the drum
  • the drum is rotated and the water in the washing machine is circulated to the laundry in the drum to preheat the drum and the tub, so that no subsequent cooling of the washing liquor takes place during a subsequent addition of detergent and an ongoing washing phase.
  • the DE 10 2007 037 159 A1 describes a method for washing laundry in a washing machine with a tub, in which a drum is rotatably mounted, with the phases washing (WA), in which the predetermined amount of water is heated to a predetermined temperature (T1), rinsing (Ri) and Final spin (FS), the washing phase (WA) comprising a first section (WA1) which is carried out with a first amount of water at the predetermined temperature (T1), followed by a second section (WA2) in which an additional amount of water is added to the first amount of water, the increased amount of water in the second section being heated to another predetermined temperature (T2).
  • the DE 10 2012 023 084 A1 describes a method for washing laundry items in a program-controlled domestic appliance for the care of laundry items, in which a washing liquid present in a tub is heated, a washing temperature is set, laundry-specific and / or device-specific parameters are recorded and, depending on the parameters, the heating of the washing liquid Setting a specific target temperature (Tz) is carried out.
  • a heating device for heating the washing liquid is activated and the washing device is heated with the heating device Mains phase temperature (Tn) is heated, which is lower than the target temperature (Tz), which is assigned to a washing method selected by an operator.
  • the DE 197 30 422 A1 describes a method for wetting laundry in a program-controlled drum washing machine for the home, the washing drum of which is rotatably arranged in a tub, which is equipped with a fresh water supply, a water level regulator and a detergent dispenser.
  • the washing drum with the dry laundry is first brought up to a rotational speed forming a laundry ring, the washing drum is then stopped and then wetting liquid and optionally detergent are added.
  • the free liquor in the bottom of the lye tub is heated to a predetermined temperature while the washing drum is still at a standstill, after which a reversing process is initiated and the laundry is moistened with the preheated wetting liquid. Then the free liquor in the bottom of the lye tub is heated to the set washing program end temperature.
  • Another method for wetting laundry in a washing machine is in DE 10 2007 028 212 A1 disclosed.

  • Steps (a) to (c) are thus carried out in a wetting phase.
  • aqueous liquid means in particular water or wash liquor.
  • the temperature sensor used here controls the heating in such a way that the temperatures to be set can be set.
  • the predetermined temperature T1 is not particularly limited. However, T1 is preferably in the range from 30 to 60 ° C.
  • the quantity q1 is determined as a function of an energy Emax that can be used for the method and the predetermined temperature T1, a relationship between Emax, T1 and q1 being stored in the control device.
  • the method according to the invention makes it possible to respond flexibly to the requirements of a laundry to be cleaned. It can make sense to heat a quantity of water to be heated in one or more steps.
  • the amount q 1 of the aqueous liquid is heated to the predetermined temperature T 1 in one step. If in this case the heated amount q 1 is brought into contact with the laundry for wetting, the laundry can be heated relatively quickly. This can be advantageous in view of the reduced time required for a subsequent washing phase. However, at a high predetermined temperature T 1 there is in principle the risk that certain impurities, in particular protein-containing soiling, are burned into the laundry.
  • partial quantities q 1 ' are preferably used, depending on an energy heating that can be used for heating q 1 in step (b) and which is less than a maximum energy max that can be used for the method, and the predetermined one Temperature T 1 defines the subsets q 1 ', after filling them into the tub, heating takes place, a relationship between heating , T 1 and the subsets q 1 ' being stored in the control device . It can be heated to the temperature T 1 after the addition of the subsets q 1 '. However, less heating can also take place as long as the total amount q 1 of aqueous liquid is heated to T 1 in step (b).
  • the quantities q n with n 3 3 are totally dependent on the quotient q 1 / q Schedule will be added.
  • the total amount q 1 + q 2 or generally q total of aqueous liquid is preferably an optimal amount of water, which therefore leads to the highest washing effect with a certain input of energy for heating the aqueous liquid.
  • q total can be specified or determined while the method according to the invention is being carried out. For example, during the method according to the invention when using a pressure sensor to determine a water level in the tub from the pressure curve with smaller amounts of water before, during and after heating, the optimal amount of water is determined. This is particularly dependent on a load of laundry, which can be determined, for example, by measuring the weight of the laundry.
  • the heater is generally turned off during step (c).
  • the time of adding the detergent required for the washing phase is not particularly limited.
  • the detergent is added as early as possible to enable an optimal washing phase.
  • it may make sense to either avoid relatively high temperatures or set them as early as possible.
  • Enzymes in a detergent are often sensitive to excessive temperatures.
  • bleaching agents usually require higher temperatures to develop a bleaching effect.
  • a method is preferred according to the invention in which the detergent for the washing phase (d) is contained in q 1 and / or q 2 .
  • the amount of water q 2 is chosen such that the temperature of the amount of water q 1 + q 2 does not fall below a predetermined minimum value T wash for the temperature of the aqueous Liquid falls. This takes into account that the heated to T 1 water quantity q 1 before the start of the washing phase due to the addition of relatively cold water quantity q cools second It is then preferably ensured that a minimum temperature T wash of the wash liquor is given for the wash phase.
  • Temperatures T q1 and T q2 are generally in the range of 5 to 18 ° C.
  • the temperatures T q1 and T q2 are preferably the same and in particular have the temperature of a tap water used.
  • the amount of water q 1 in step (b) is first reduced to a Temperature T P1 ⁇ T 1 heated and after wetting the laundry and possibly filling the amount of water in the tub to q 1 , heating the aqueous liquid in the tub to a temperature T P2 , T P1 ⁇ T P2 ⁇ T 1 applies.
  • the laundry is generally wetted after heating in that the laundry is brought into contact with the aqueous liquid heated to T 1 on account of a suitable movement program for the drum, which can also have scooping devices for the aqueous liquid. Due to the temperature condition T P1 ⁇ T P2 ⁇ T 1 , this procedure can be used, for example, to avoid the burning-in of protein-containing contaminants.
  • T P1 is preferably in the range from 25 to 35 ° C.
  • step (b) T P2 ⁇ T 1 and after reaching the temperature T P2 , the laundry is rewetted with the aqueous liquid while rotating the drum, and then the amount of water q 1 , if necessary after filling up the amount of aqueous liquid flowing back into the tub to q 1 , to the temperature T 1 .
  • Filling the amount of water to q 1 after wetting the laundry has taken into account the fact that due to the wetting process, water is bound in the laundry which can no longer flow back into the tub.
  • this additional water quantity to be used which is referred to simply as ⁇ q, can be taken into account for the washing phase by reducing the partial quantities to be added in steps (c) and (d), so that the total q total is preferably not exceeded.
  • the amounts q 1 , q 2 and / or q total are determined as a function of a loading amount of the drum and / or the type of laundry.
  • the quantities q 1 , q 2 and / or q total in the control device of the washing machine as a function of a load quantity of the drum and / or the type of laundry deposited. If the wetting process and the washing phase are matched to laundry items of different sizes, it can be prevented that with very large laundry items no complete wetting takes place, but in comparison with small laundry items the wetting phase takes too long, based on their wetting success. This also improves wetting uniformity.
  • the load of the drum with laundry can be determined automatically using a suitable determination method or can be set manually by a user of the washing machine.
  • the type of laundry can be determined using a suitable determination method, for example an optical method, or can be set manually by a user of the washing machine.
  • step (a) and / or (b) in particular in step (b), the drum is preferably rotated at a higher rotational speed than in step (c).
  • step (a) and / or (b), particularly in step (b), the drum is rotated at an average rotational speed in the range from 40 to 60 revolutions / min and more preferably in the range from 45 to 55 revolutions / min.
  • the drum in step (c) is rotated at an average rotational speed in the range from 25 to 45 revolutions / min and more preferably in the range from 30 to 40 revolutions / min, in particular in the range from 31 to 39 revolutions / min.
  • the drum is rotated at an average speed of rotation in the range of 40 to 60 revolutions / min and more preferably in the range of 45 to 55 revolutions / min.

  • the washing machine according to the invention contains a measuring device for determining an amount of aqueous liquid introduced into the tub.
  • a clock, a flow meter and / or a water level sensor are preferably provided as the measuring device.

  • the washing machine and method according to the invention have numerous advantages. It is thus possible to carry out a washing process in a more energy-efficient manner by using an already heated aqueous liquid for wetting and preheating the laundry. It is sufficient to use a relatively small amount of the aqueous liquid and in any case not a large amount which is generally necessary for a washing phase.
  • the laundry can be preheated in this way with a relatively warm aqueous liquid, so that even with a later addition of colder water, in embodiments of the invention in one or more separate portions, washing can be carried out with a relatively high washing temperature.
  • the temperature of the laundry is a decisive factor in the washing phase, since this is where the interaction with a washing liquor takes place. Since, according to the invention, the water used for wetting is heated relatively early, in principle a faster-running washing process can also be implemented.
