Abstract

Die Erfindung betrifft ein Staubsaugergebläse (3) mit einer Einlassöffnung (7), durch die Luft in das Staubsaugergebläse (3) einströmen kann, wobei die Einlassöffnung (7) einen Durchmesser von mindestens 38 mm, höchstens 50 mm bei einem Außendurchmesser des Laufrads (6) von mindestens 60 mm, höchstens 100 mm hat. Zudem betrifft die Erfindung ein Laufrad (6), das einem kreisförmigen Bereich (23) einer Bodenscheibe (27) keine Flügel (24) aufweist, wobei dieser Bereich mindestens 38 mm, höchstens 50 mm bei einem Außendurchmesser des Laufrads (6) von mindestens 60 mm, höchstens 100 mm durchmisst.The invention relates to a vacuum cleaner fan (3) having an inlet opening (7) through which air can flow into the vacuum cleaner fan (3), the inlet opening (7) having a diameter of at least 38 mm, at most 50 mm at an outer diameter of the rotor (6 ) of at least 60 mm, not more than 100 mm. In addition, the invention relates to an impeller (6) having a circular area (23) of a bottom disc (27) no wings (24), said area at least 38 mm, at most 50 mm at an outer diameter of the impeller (6) of at least 60th mm, not more than 100 mm.

Durch die besonders große Einlassöffnung (7) kann der aerodynamische Widerstand in einem Staubsauger (28) gesenkt werden und eine hohe Saugleistung gewährleistet werden.
