Definitions
- the invention relates to a method for operating a program-controlled dishwasher, with a softening device, consisting of an ion exchanger, a Salt storage container and a regeneration water storage container, the dishwasher with from the sub-programs - pre-rinsing, cleaning, intermediate rinsing, rinsing, Drying, adding an amount of brine to regenerate the ion exchange and rinsing the exchanged hardness formers from the regenerated ion exchanger - selectable Rinse programs can be operated, and in the sub-program cleaning the sub-program addition a brine quantity for regenerating the ion exchanger is displayed.
- a method of the type mentioned is known from DE-OS 39 21 422. Usually takes place on the sub-program adding a brine quantity to regenerate the ion exchanger adding an amount of backwash water to rinse out the replaced ones Hardener from the regenerated ion exchanger. In the aforementioned process the sub-program adding a quantity of backwash water to rinse out the replaced ones Hardener from the regenerated ion exchanger following the sub-program Clean and then the intermediate rinse program follows.
- the procedure is, as usual, the addition of a quantity of backwash water in the sub-program for rinsing out the exchanged hardness formers from the regenerated ion exchanger added amount of backwash water to avoid extending the program run time and limit unnecessary water consumption to a small amount of water, which only rinses out most of the hardness formers from the ion exchanger.
- This So-called backwashing of the regenerated ion exchanger is then carried out at the aforementioned Procedure in the subsequent sub-program intermediate rinsing, since it is a sub-program without the addition of detergent to dilute the detergent by rinsing it out Avoid brine components continued.
- the added Backwashing water amount usually to the addition of the largest amount of brine to Regenerate the ion exchanger and thus constantly on the largest amount of the hardness pattern to be rinsed out of the regenerated ion exchanger results in overall for rinsing the exchanged hardness from the regenerated
- the amount of backwash water added to the ion exchanger is approximately 4.2 liters of water, independently how big is the amount of hardening agent really to be rinsed out. this means in most cases unnecessary water consumption.
- the insertion of the sub-program Add a quantity of backwash water to rinse out the exchanged hardness agents from the regenerated ion exchanger between the sub-program cleaning and the Sub-program intermediate rinsing also means an extension of the program execution time.
- the invention is therefore based on the object in a method of the aforementioned Kind in a simple way a further shortening of the program duration and a to achieve further water savings.
- This object is achieved in that the rinsing of the exchanged Hardener from the regenerated ion exchanger only during the intermediate rinse program takes place in which the amount of liquid used the running washing program is adjusted.
- the duration of the rinse program by the duration of the partial program saved adding a backwashing water quantity for rinsing out the exchanged hardness formers from the regenerated ion exchanger shortened.
