Abstract

Staubsauger (1) mit einem Fliehkraftabscheider (2), der einen Lufteinlasskanal (3) aufweist, der mit einer Saugluftführung (4) für staubbeladene Saugluft verbunden ist, einen Abscheideraum (5) und einen Luftauslass (6), der über ein Tauchrohr (7) mit dem Abscheideraum (5) in Verbindung steht, wobei der Lufteinlasskanal (3) in den Fliehkraftabscheider (2) einmündet, wobei der Fliehkraftabscheider (2) ein Luftführungsmittel (8) umfasst, wobei das Luftführungsmittel (8) eine Fläche (9) ist, die durch stetige Schraubung (10) einer Raumkurve um die Achse (11) des Fliehkraftabscheiders (2) erzeugt wird.A vacuum cleaner (1) having a centrifugal separator (2) having an air inlet duct (3) connected to a suction air guide (4) for dust-laden suction air, a separation chamber (5) and an air outlet (6) connected via a dip tube (7 ) is in communication with the separation chamber (5), wherein the air inlet channel (3) opens into the centrifugal separator (2), wherein the centrifugal separator (2) comprises an air guide means (8), wherein the air guide means (8) is a surface (9) which is generated by continuous screwing (10) of a space curve about the axis (11) of the centrifugal separator (2).

Die vorliegende Erfindung erleichtert mit einfachen und konstruktiven Mitteln die Realisierung eines Fliehkraftabscheiders (2) bei dem besonders eine Geräuschreduzierung und ein gesteigerter Volumenstrom erzielt werden. Weiter wird ein höherer Gesamtwirkungsgrad und eine Effizienzsteigerung erreicht.
