Abstract

Ein wasserführendes Haushaltsgerät, insbesondere eine Haushalt-Geschirrspülmaschine, weist eine Arbeitsbehälter (2) und eine innerhalb einer für die Zufuhr von Frischwasser vorgesehenen Wasserzulaufeinrichtung angeordneten Einrichtung (14) zum Enthärten des Frischwassers auf. Erfindungsgemäß ist in der Wasserzulaufeinrichtung eine einstellbare Teilvorrichtung (39) angeordnet, durch die die zulaufende Wassermenge in wenigstens zwei Teilmengen aufteilbar ist. Ein erster Teil der zulaufenden Wassermenge ist zuerst der Enthärtereinrichtung (14) und anschließend dem Arbeitsbehälter (2) und ein zweiter Teil direkt dem Arbeitsbehälter (2) zuführbar. Auf diese Weise hat die Flüssigkeit im Arbeitsbehälter (2) eine definierte Resthärte, die weder zu einer Trübung von zu spülenden Glasspülgutteilen noch zu Kalkrückständen auf dem Spülgut führt.

Figure 00000001
A water-carrying household appliance, in particular a household dishwasher, has a working container (2) and a device (14) for softening the fresh water which is arranged within a water supply device provided for the supply of fresh water. According to the invention, an adjustable partial device (39) is arranged in the water supply device, by means of which the incoming water quantity can be divided into at least two partial quantities. A first part of the incoming water quantity can first be fed to the softening device (14) and then to the working container (2) and a second part directly to the working container (2). In this way, the liquid in the working container (2) has a defined residual hardness, which neither leads to a clouding of glassware items to be washed nor to limescale residues on the items to be washed.
