  • laundry In a washing machine, laundry is generally treated in a washing phase for cleaning with a washing liquor containing detergent.
  • Detergents contain, in particular, surfactants as surface-active substances to form a wash suds for cleaning items of laundry, these reducing the surface tension of the water in the aqueous solution formed (wash suds).
  • the washing phase is usually followed by at least one rinsing step for rinsing out the washing liquor that has been enriched with dirt and detergent.
  • the rinsing result depends not only on the rinsing time, but also on the amount of water used and the number of rinsing steps, also known as rinsing cycles.
  • an empirically determined number of rinsing steps and a rinsing duration are generally specified. These can be adjusted by querying a turbidity sensor. If there is only a very small amount of detergent left in the items of laundry at the end of the washing phase, the rinse usually takes too long or uses too much water.
  • the individual rinsing step is time-controlled, so that the compensation process, ie the concentration compensation, between the rinsing liquid and the detergent on the items of laundry cannot be adequately taken into account. So it happens that the scavenging phase is often already over, although the equalizing process is not over yet is. On the other hand, flushing often continues even though an equalization process no longer takes place.
  • a rinsing phase that is optimally tailored to a batch of items of laundry leads not only to savings in energy and water, but also in particular to less pollution of the waste water and a shorter duration of the rinsing phase. It would therefore be desirable to take into account the detergent concentration or quantity actually still present in the rinsing liquid in a rinsing phase.

  • the pH value, conductivity value, turbidity value or temperature come into consideration as measured values.
  • the EP 0 797 761 B1 describes a method for determining the surface tension of a liquid by generating gas bubbles in the liquid, after which the surface tension in the liquid is determined by monitoring gas bubbles and wherein the gas bubbles are formed from gas generated in situ.
  • the EP 2 533 035 A1 describes a device for detecting material properties of a medium, with a measuring device including a sensor device that is connected to the medium, and a control device for controlling the sensor device with signals of a predetermined frequency range, and a control device for controlling the operation of the measuring device and specification of the predetermined frequency range, the control device being provided for determining the course of the impedance Z of the medium in accordance with the predetermined frequency range as a function of the frequency, and for outputting a detection signal, and the control device being provided for evaluating the detection signal of the control device, determining a plurality of characteristic Points (P1 to P4) of the course of the impedance Z and generation of a result signal relating to the properties of the medium.
