A second rinsing liquor line 2 in FIG. 3 leads from the rinsing pump to a sewer line, via which rinsing liquor can be conveyed out of the dishwasher 9. The sewer line has a check valve 5 to prevent backflow of the spent wash liquor from the sewer line into the dishwasher 9. In order to better control the flow paths of the wash liquor through the Spülflottenleitungen 1, 2, 3, a shut-off valve 6, 7, 8 are provided in the Spülflottenleitungen 1, 2, 3, which the respective Spülflottenleitung 1, 2, 3 at Open or close demand. The shut-off valve 7 in the first rinsing liquid line 1 between the suds pump and the foil bag 17 serves, in particular, to prevent an untimely reflux of the rinsing liquor from the foamed foil bag 17 via the suds pump back into the sump. When using a feed pipe, which ends in the upper region of the storage container, the shut-off valve 7 is not required (not dargesteUt). The emptying of the film bag 17 in the washing container 11 or in the sewer pipe 5 erfojgt generally by gravity by means of appropriate control by at least one shut-off valve or a water diverter. The shut-off valve can also be integrated with the instantaneous water heater.

However, the control of the flow paths of the rinsing liquor can also be carried out by a water diverter 4, which opens either the first rinsing liquor line 1 from the suds pump to the film bag 17 or the second rinsing liquor line 2 from the drain pump to the sewer. In this way, during operation of the suds pump, either the foil bag 17 is filled with rinsing liquor via the first rinsing liquor line 1, or rinsing liquor is conveyed via the second rinsing liquor line 2 from the dishwasher 9 into the sewer line.

In this embodiment of the invention The method according to the invention, the circulating pump is used to füUen the film bag 17 with rinse. The plastic bag 17 is attached via a first rinsing liquid line 1 with the shut-off valve 7 open from the circulating pump to the film bag 17, the circulation pump drawing the rinsing liquor from the sump at the bottom of the rinsing container 11. When the shut-off valve 7 is closed, the rinsing liquor is conducted via the water distributor 4 into the spray arms. The flow resistance of the spray arms with open shut-off valve 7 is sufficient that the film bag 17 is gefüUt. For this reason, in general, no additional shut-off valve (not shown) immediately before the water diverter 4 or closing of the water diverter 4 is required to fill the film bag 17.

As a result, filtered washing liquor is pumped into the film bag 17 in a particularly advantageous manner. The rinsing liquor sucked by the circulating pump in the pump sump is controlled by a filter system normally arranged in the pump sump, generally consisting of several filters, e.g. R a coarse and fine filter, filtered because the intake pipe of the circulation pump is arranged differently in the pump sump than the intake pipe of the drain pump. As a result, the residence time of the rinsing liquor in the film bag 17 can be increased and there are no or only very small deposits in the film bag 17 and / or in the rinsing liquor line 1. This blockages can be avoided by deposits in the Spülflottenleitongen 1 and / or in the check valve 7. Furthermore, the bacterial, germ and Ajgen growth is significantly limited, because these creatures food is withdrawn. The emptying of the film bag 17 in the washing container 11 or in the sewer line 5 erfojgt generally by gravity by opening the shut-off valve 7. With open shut-off valve 7, the rinse liquor runs through the Spülflottenleitung 1 by the switched-off circulating pump by gravity preferably in the pump sump.

The operation of the drain pump, the circulation pump and the operation of the water switch 4 and the shut-off valve 1 is coordinated and controlled by the electronic program control.

The wash liquor stored in the foil bag 17 can be used in addition to the preferred use for a pre-rinse cycle of a subsequent cleaning program for a Zwischenschluck (cleaning the sieve by brief alternate operation of the lye and circulating pump).

[048] The film bag 17 and / or the Spülflottenleitungen 1, 2, 3 can on the water-bearing inner walls antibakterieU, z. R be coated with Agion. As a result, significantly fewer bacteria or germs settle on the inner walls of the parts 1, 2, 3, 6, 7, 8, 17. It can thereby be increased in the film bag 17, the service life of the wash liquor and blockages of Spülflottenleitungen 1, 2, 3 by deposits can be avoided.

All of the features of the invention described above for a dishwasher according to the invention and the method according to the invention with a flexible film bag (claims 1 and 17) also apply to a dishwasher according to the invention and to the method according to the invention with a non-flexible storage container (claims 16 and 21) which the storage container of the circulating pump can be filled with filtered rinsing liquor or befüUt.
