Über dem Ionenaustauscher weist die Behältereinheit eine Salzvorratskammer 5 auf, die durch einen, durch die Spülbehälterseitenwand in den Spülraum geführten und durch einen Deckel oder dergleichen verschließbaren Einfüllstutzen 6 mit Salz auffüllbar ist. Von der Salzvorratskammer 5 führt eine Soleleitung 7 zum Ionenaustauscher 2. Oberhalb der Salzvorratskammer bildet die Behältereinheit 1 einen mehrkammerigen Speicherbehälter 8, dessen Kammern mit einer Verteilerkammer 9 strömungsverbunden sind. In der Verteilerkammer 9 ist ein Stellelement 10 vorgesehen, das einen Wasserhärteschalter bildet. In Abhängigkeit von der Härte des Frischwassers am Aufstellort der Geschirrspülmaschine wird das Stellelement in eine bestimmte Lage gebracht. Hiermit ist es möglich, die dem Ionenaustauscher zur Regenerierung seiner Füllung aus der Salzvorratskammer zuzuführende Solemenge dadurch zu bemessen, daß der Salzvorratskammer aus dem Speicherbehälter lediglich der Wasservorrat einer Kammer oder der Wasservorrat aus mehreren Kammern zugeführt wird.The container unit 1, which is made of plastic and is arranged next to a side wall of a dishwashing container (not shown) of a dishwasher, contains an ion exchanger 2, the ion exchange mass of which is located in a chamber of the container unit between sieve walls 3, 4. Above the ion exchanger, the container unit has a salt storage chamber 5, which can be filled with salt through a filler neck 6, which is led through the side wall of the washing container and can be closed by a cover or the like. A brine line 7 leads from the salt storage chamber 5 to the ion exchanger 2. Above the salt storage chamber, the container unit 1 forms a multi-chamber storage container 8, the chambers of which are flow-connected to a distributor chamber 9. In the distribution chamber 9, an actuator 10 is provided, which forms a water hardness switch. Depending on the hardness of the fresh water at the installation site of the dishwasher, the control element is brought into a certain position. This makes it possible to measure the amount of brine to be supplied to the ion exchanger to regenerate its filling from the salt storage chamber by supplying the salt storage chamber from the storage container with only the water supply from one chamber or the water supply from several chambers.
