Abstract

Die Erfindung betrifft eine Vorrichtung im Wasserzulauf eines Haushaltsgerätes, insbesondere einer Geschirrspülmaschine, mit einer Wasserrücklaufverhinderungseinrichtung (1). Erfindungsgemäß wird im Einströmbereich (6) der Wasserrücklaufverhinderungseinrichtung (1) eine Einrichtung (10) zum Feinverteilen von Luftblasen vorgesehen. Damit wird verhindert, daß größere Luftblasen (12) in die Wasserrücklaufverhinderungseinrichtung (1) gelangen und dort durch Zerplatzen an einer Luftöffnung (3) zur Geräuschbildung führen.

The invention relates to a device in the water inlet of a household appliance, in particular a dishwasher, with a water return prevention device (1). According to the invention, a device (10) for the fine distribution of air bubbles is provided in the inflow region (6) of the water return prevention device (1). This prevents larger air bubbles (12) from entering the water return prevention device (1) and causing noise there by bursting at an air opening (3).
