  • chemical washing substances are known to be added, wherein in this process section mainly the cleaning of the ware is carried out by its adhering dirt particles.
  • residues of dirt particles and rinsing liquid residues are removed with residues of chemical washing substances from the cleaning process step.
  • EP 0 852 929 A2 discloses a method for operating a dishwasher, according to which the dishwasher is merely started at the start of the program and parameters to be set for the progress of the rinsing operation depend on at least one of the rinsing process which is necessary and influenced by it; adjusted parameters are set.

  • the at least one parameter to be set for the progress of the rinsing process is set in the preselected range limits as a function of at least one respectively detected parameter.
  • EP 0 553 803 B1 discloses a program sequence for cleaning freshly soiled items in a dishwashing machine, in which initially two pre-rinsing courses with cold rinsing liquid are followed directly by two rinses with hot rinsing liquid.
  • This program sequence is compared to the above-described program sequences, in which between program sections with hotter, d. H. by intended heating means heated rinsing liquid, those with cold, d. H. Zu einstemperaturfuger, rinsing liquid are connected, from a purely energetic point of view in the advantage.
  • At least one dilution step is provided in this process section pre-rinse.
  • the rinsing liquid initially used for pre-rinsing which can be soiled to varying degrees, is replaced by the addition of fresh, ie. H. not soiled, rinsing liquid from storage vessels of the dishwasher and / or the water supply at least partially mixed with this.
  • fresh, ie. H. not soiled, rinsing liquid from storage vessels of the dishwasher and / or the water supply at least partially mixed with this.
  • the dilute rinsing liquid has a lower degree of contamination and thus a better cleaning power.
  • it is provided to pump off part of the already soiled rinsing liquid before and / or during the feeding of a fresh rinsing liquid volume.
  • the rinsing fluid volume which is generally initially provided at the beginning of the program section for rinsing, amounts to approximately 4 l for a dishwasher with space for 12 normal place settings. Laboratory tests have shown that the cleaning result of the items to be cleaned is acceptable on average for all degrees of soiling, if the volume of the partly pumped dirty rinsing liquid advantageously by an equal volume of fresh, d. H. not soiled, rinsing liquid is replenished.
  • the rinsing liquid volume is pumped off approximately halfway and replenished.
  • dishwashers which are not equipped with a possibility for detecting the degree of turbidity, ie the degree of soiling of the rinsing liquid, are operated in a simple way to save water, being accepted that with increasing degree of contamination of the rinsing liquid, the cleaning result of the ware compared to that, the less dirty flushing fluid is applied, is slightly worse.
  • a basically half pumping and refilling of rinsing liquid is possible.
  • the duration of the program section prewash is set variably. This can be done for example by the erfirdungsstrue user-related selection of the wash program depending on the degree of soiling of the set dishes, but also programmatically in response to various parameters that are recorded during the program or deposited in tables in a microprocessor control. With respect to a water supply with respect. A fixed monitoring levels of the liquid level in the dishwasher, which z. B. is set to a pump speed of 1,900 rpm of a circulating pump laboratory tests have shown that it makes sense in terms of good cleaning results that a process section pre-rinsing with a dilution step lasting at least longer than 10 minutes. For comparison, a conventional pre-rinse takes an average of 3 to 10 minutes.
  • the pre-rinsing process section can be terminated by a dilution step or by completely pumping out the rinse liquid used.
  • the former means that a partial volume of the rinsing liquid is partially reused in the following program section cleaning, which is favorable in terms of the lowest possible water consumption.

B. supplied by switching heating means provided, so that an increase in temperature of the rinsing liquid during this process section only as a result of the absorption of stored energy throughout the dishwasher.
  • Such tempered rinsing liquid is referred to below as lukewarm.
  • the process section screen cleaning will last much shorter than the previous process stage cleaning or the subsequent process section rinse, because energetically it is particularly favorable residues of stored energy for heating the rinsing liquid in to use the following process section rinse.
  • the volume of the rinsing liquid supplied is less than the respective maximum existing volume of rinsing liquid in the dishwasher during the process sections cleaning or rinsing, so that thereby the residence time of the rinsing liquid in the dishwasher and thus the possibility of energy extraction, as well as the total duration of this process section is minimized, which makes sense in terms of reducing the energy and water consumption, as already mentioned above.
  • At least one additional liquid-conducting intermediate flushing process section is switched off for the purpose of completely removing the residues of chemical substances from the cleaning process section, which comprises at least one dilution step, preferably at the end of the process section Intermediate rinse, has.
