  • a fabric softener that is frequently used in a respective last rinse of laundry should remain in the laundry. That is why the last rinse is usually a fabric softener, in which fabric softener is added.
  • a fabric softener is usually a preparation based on cationic surfactants; instead of or in addition to this, another substance for treating the laundry in a final rinse and for remaining in the laundry can be added, in particular an impregnating agent, a fragrance or a laundry starch.

  • This has a recovery container for storing the rinsing liquid inside the washing machine, as well as a recovery pump, a feed channel and a detergent holder with a larger and a smaller chamber. Before the rinsing liquid enters the recovery container, it absorbs the cleaning agent contained in the smaller chamber, which is intended to reduce the contamination of the stored liquid due to a disinfecting effect.
  • the DE 197 09 085 A1 describes a method for washing laundry, in particular in a household washing machine, in which the laundry in a tub is treated with washing liquid during a washing section and with rinsing liquid during subsequent rinsing sections and in which the tub is emptied at the end of the respective washing / rinsing section, wherein the washing liquid and / or the rinsing liquid of at least one rinsing section are emptied into a collecting container and are reused after being processed by a reverse osmosis, micro, ultra or nanofiltration process with intermediate storage in a storage container.
  • the prepared washing or rinsing liquid is fed to a later rinsing section of the same program sequence.
  • the DE 197 45 824 A1 describes a household appliance performing washing functions, for example a washing machine or dishwasher, with a storage container for water which is arranged below the container, for example the tub, in the housing of the household appliance. With this arrangement, despite the combination of the household appliance with a storage container does not increase the overall volume of the household appliance itself.
  • the WO 2010/115683 A1 describes a water-carrying household appliance such as a washing machine with an ion exchanger as a desalination device for generating desalinated water and a rinse water reservoir and an associated method.

  • the water in the circulation circuit outside the washing container is irradiated with ultraviolet light in order to achieve a hygienic effect even at low washing temperatures and without the use of bleaching agents.
  • fabric softener is preferably added after a certain amount of time without fabric softener and the water has been pumped around, as the fabric softener causes the rinsing water to become cloudy, which reduces the effect of UV radiation and thus the hygiene effect.
  • the EP 2 236 657 A1 describes a washing machine comprising, among other things: a washing container; a water supply valve that is opened and closed to supply tap water into the washing tank; a water circulation passage having opposite ends connected to the washing tank; a circulation pump provided in the water circulation passage for pumping water from the washing tank through one of the opposite ends of the water circulation passage and for supplying the pumped water back to the washing tank through the other end of the water circulation passage; and a generator producing cleaning air, control means causing the generator to mix the cleaning air with the circulating water.

  • this document discloses a method for fabric softening laundry in a washing machine with a program controller for controlling a program sequence, a drum rotatably mounted in a tub in which the laundry is located, a water supply system, a fabric softener reservoir, a tubing system at the bottom of the tub and a drive motor for the drum, wherein a fabric softener cycle comprises the steps of introducing a first liquid containing no fabric softener into the drum, rinsing the laundry with it and pumping out a portion of the first liquid, after pumping out a portion of the first liquid and a In a further rinsing step, a second liquid containing fabric softener is introduced from the fabric softener reservoir into the drum.
  • a rinse cycle is generally understood to mean a section of the wash program in which a first liquid, preferably water provided via the house supply network or washing liquid stored in the washing machine from previous washing processes, is introduced into the tub and thus the drum. By moving the drum depending on the washing program, the laundry is mixed with the first liquid, which is then pumped out. The washing liquor enriched with impurities and detergent in the previous pre-wash and / or main wash cycle can thus be rinsed out of the laundry.
  • a first liquid preferably water provided via the house supply network or washing liquid stored in the washing machine from previous washing processes
  • the number of rinsing cycles provided and the amount of liquid provided for a rinsing cycle are usually derived from the washing program. This means, for example, that the amount of liquid that is introduced into the drum per rinse cycle is predetermined by the washing program and is consequently controlled accordingly via the program control. Depending on the washing machine and / or washing program, current factors such as the amount of laundry loaded on the drum, the degree of soiling of the laundry and / or the hardness of the water may also play a role. On average, in a washing machine with a load of 5 to 6 kg of laundry, approx. 20 l of liquid are required for one wash cycle.
  • steps (a) and (b) serve in particular to rinse out residues of washing liquor and impurities from the laundry. Consequently the duration of these steps, in particular of step (b), is essentially determined by the replacement processes required for adequate flushing.

  • the fabric softener can be a high viscosity liquid or a solid.
  • the contents of the fabric softener reservoir would be added to the tub or the drum is generally not optimal due to the opening of a valve and the action of gravity.
