  • the process section cleaning is followed by a process section Intermediate rinsing, in which the now existing fresh or diluted flushing liquid passive, d. H. exclusively by removing energy from the heat capacity of the dishwasher is heated, so that this during their circulation remaining dirt left over and chemical residues of the process section cleaning removed.
  • the circulation the rinsing liquid is in the process section intermediate rinsing for a duration of about 2 to 10 minutes instead.
  • alternative Intermediate rinsing can also be used as pulse rinsing at reduced maximum rinsing fluid volume with respect to the maximum Rinsing fluid volumes of the cleaning are operated
  • the intermediate flushing stage is completed or partial emptying finished.
  • the rinse tank is a defined Rinsing fluid volume supplied. This can of be fixed in front and / or variable depending on various parameters can be set. A dependent Size is thereby the concentration of thereby actually in the rinse liquid existing rinse aid, since these immediate Influence on the rinse aid result and thus on the subsequent achievable drying result of the ware increases.
  • the rinse liquid in the case of a low concentration of rinse aid at the beginning of the program section rinse the rinse liquid as low as possible, but possibly depending on Turbidity of the rinsing liquid to be supplied. Otherwise it is the concentration of the rinse aid at the beginning of the program section Clear rinse above average or sufficient high, so can the concentration of the rinse aid by feeding a defined adjustable Spülillonkeitsvolumens be set to a predetermined concentration.
  • the Rinsing liquid with already dissolved rinse aid, as well with rinse aid still to be dissolved, is now preferred to a dissolution temperature above the dissolution temperature a ph value and / or temperature dependent dissolving Rinse clearer.
  • This dissolution temperature is currently above 58 ° C (for the 3in1 combination Calgonite Powerballs®).
  • the rinse liquid heated and circulated At the end of the program section rinse the rinsing liquid is as far as possible by pumping removed from the washing container.

  • the intermediate rinsing during the liquid-carrying process sections can preferably be designed as pulse rinsing be, d. H. that intermediate rinsing during the process section the circulation pump repeated for a predeterminable or determinable Duration is switched on and off.
  • the duration Turning on the circulation pump and off the Circulating pump depending on a level of flushing liquid in the washing container, which corresponds to a lower fill level, in which the circulating pump does not suck in air. Due to the above there are further dependencies to the speed of the circulation pump, which increases with increasing Speed more rinsing fluid takes the sump.
  • the design the pulses of turning on and off the circulation pump is also as a function of a turbidity measurement of the rinsing liquid adjustable, so can the duration of low pollution degree the switching of the circulation pump against the duration of switching off the circulation pump can be shortened and with increased degree of contamination be extended accordingly.
  • the invention is based on a Method for operating a household dishwasher, which for the use of 3in1 combination preparations, ie of those with the active ingredients cleaner, rinse aid and Softener, is suitable, explained in more detail.
  • the single figure shows a schematic of the individual process sections a rinse cycle. It is assumed that that the water of the supply line is essentially soft is and thus has a low degree of hardness.
  • the rinsing liquid is at the maximum predetermined temperature circulated about 10 to 30 minutes in the washing and thereby the washed items to be cleaned acted upon.
  • the rinse fluid volume will be for a following Intermediate rinse program section fresh and filled exclusively by removing energy in the heat capacities of the dishwasher is stored, heated and circulated.
  • the maximum amount of rinsing fluid supplied can be in Dependence of a turbidity measurement and / or a concentration measurement of existing rinse aid, according to the dilution principle works, can be varied.
  • the process section intermediate rinsing goes after a dilution step or after a complete drainage, not shown e.g. Dependence of turbidity level in the program section Rinse over. This is at least partially the Rinse fluid volume increases and preferably reaches the maximum rinsing fluid volume of the program section Clean.
  • the rinsing liquid volume by appropriately evaluated measurement results provided sensors also exactly to a predetermined concentration range of the rinse aid.
  • the value of then rinse liquid volume to be supplied by the arithmetic unit the program sequence control are calculated. Consequently the duration of the intermediate rinsing varies between 2 to 10 min and the duration of the rinse about between 2 to 15 min.
  • the Rinse fluid volume is in the rest of the program now to a temperature above a pH or temperature dependent Dissolution temperature of the rinse aid increased, the dissolution temperature the rinse aid is currently at about 58 ° C, so that to a minimum rinse temperature of 60 to 70 ° C is heated.
