Abstract
Eine Pumpe (11) für einen Geschirrspüler weist einen Impeller (19) zur Förderung von Fluid auf, wobei sie als Kreiselpumpe ausgebildet ist mit zentralem axialem Ansaugen (16) und radialem Ausströmen (18) des zu fördernden Fluids. Der Impeller verläuft an einer Unterseite über einem Pumpenboden, wobei radial außerhalb des Impellers mehrere feststehende Strömungsleitschaufeln (25a,25b) angeordnet sind, die schraubenartig verlaufen mit in Drehrichtung des Impellers (29) verlaufender Steigung weg vom Pumpenboden (15a). Mindestens eine Strömungsleitschaufel (25a,25b) reicht bis an die Unterseite des Impellers zum Abgreifen eines umlaufenden Schlauchs aus Fluid mit Luftblasen darin. A pump (11) for a dishwasher has an impeller (19) for conveying fluid, wherein it is designed as a centrifugal pump with central axial suction (16) and radial outflow (18) of the fluid to be delivered. The impeller extends on an underside over a pump bottom, wherein radially outwardly of the impeller several fixed Strömungsleitschaufeln (25a, 25b) are arranged, which extend helically with in the direction of rotation of the impeller (29) extending slope away from the pump bottom (15a). At least one flow vane (25a, 25b) extends all the way to the bottom of the impeller for tapping a circumferential tube of fluid with air bubbles therein.
