Definitions

  • the circulating pump can be operated in particular during the pre-wash cycle or in the rinse cycle with a lower flow rate, which can achieve the effects described above.
  • This mode of operation in which the circulating pump in addition to the rinsing liquid also partially draws air can also have a pulse-like course of the water jet generated by the circulation pump and the spray water or water pressure result, which also leads to the desired effect that the water jet acting on the dishes is less intense and the detachment of food particles from the dishes is distributed over a longer period of time, whereby peak levels of flushing residues in the washing liquid are reduced or flattened.
  • a variation of the rinsing liquid level in the dishwasher can be done for example by the supply of fresh water, which causes an increase of the rinsing liquid level.
  • a rinsing pump for pumping rinsing liquid out of the dishwasher during a rinsing cycle, in particular during the pre-rinsing cycle is preferably operated at least temporarily.
  • the method or washing program S for operating a dishwasher according to the prior art is composed of several partial program steps: pre-rinsing 1, cleaning 2, intermediate rinsing 3, rinsing 4 and drying 5.
  • the dishwasher has a circulation pump, which is a rinsing liquid to a spray device for loading stored in the washing and to be cleaned Spülgut promotes.
  • the circulating pump according to the prior art is always operated with full or at least the same power U 1 .
  • the existing in the dishwasher filter systems can clog with flushing residues, which hinders the water cycle in the dishwasher. This can lead to back contamination of the items to be washed by comminution and fine distribution of the rinsing residues deposited on the filter systems and thus to a reduction of the cleaning effect of the dishwasher.
  • FIG. 2 shows a diagram illustrating the operation of the circulation pump and the emergence of flushing residues in the washing liquid in a wash program E according to a preferred embodiment of the method for operating a dishwasher according to the present invention.
  • the time t is plotted on the X-axis and the intensity of the amount of flushing residues in the rinsing fluid from 0% to 100% is plotted on the Y-axis.
  • the diagram of FIG. 2 a curve U 2 for illustrating the operation or the performance of the circulating pump in a washing program E of a dishwasher according to a preferred embodiment of the present invention.
  • the percentages plotted on the Y-axis do not relate to the capacity of the circulation pump, but only to the intensity of the emergence of flushing residues in the washing liquid.
  • the method begins to operate a dishwasher according to a preferred embodiment of the invention with the partial program steps pre-rinse 1 and cleaning 2; Further partial program steps, such as intermediate rinsing 3, rinsing 4 and drying 5 may follow.
  • the dishwasher has a circulation pump, which conveys rinsing liquid to a spraying device in order to charge the rinsing liquid stored in the rinsing container and to be cleaned.
  • the circulating pump is operated with variable power U.
  • the circulation pump is operated in particular at the beginning of the pre-rinsing phase 1 with less than the maximum power.
  • the inventive method for operating dishwashers thus has the advantage that the action of the water jet acting on the items to be washed by the spraying device does not always take place with maximum, but with reduced and variable strength.
  • This can be in FIG. 2 at the flatter than in FIG. 1 decaying curve R 2 , which represents the intensity of the emergence of flushing residues in the flushing liquid.
