Abstract
Ein Staubsauger (1) mit einem Luftströmungskanal (4) und einem sich an den Luftströmungskanal (4) anschließenden ersten Luftströmungsumlenkabschnitt (5), in dem die Luftströmung um einen Umlenkwinkel aus einer Ebene des Luftströmungskanals (4) herausgelenkt wird. Der Luftströmungskanal (4) wird durch mindestens eine Trennwand (7), die im Wesentlichen den gesamten Querschnitt des Luftströmungskanals (4) durchmisst, in mindestens zwei parallel verlaufende Teilkanäle (8, 9) unterteilt. Die Trennwand (7) ragt wenigstens teilweise in den ersten Luftströmungsumlenkabschnitt (5) hin.A vacuum cleaner (1) having an air flow passage (4) and a first Luftströmungsumlenkabschnitt (5) adjoining the air flow passage (4), in which the air flow is deflected by a deflection angle from a plane of the air flow passage (4). The air flow channel (4) is subdivided into at least two parallel partial channels (8, 9) by at least one dividing wall (7), which measures substantially the entire cross section of the air flow channel (4). The partition (7) projects at least partially into the first Luftströmungsumlenkabschnitt (5).
Durch die erfindungsgemäße Trennung des Luftströmungskanals 4 und der Luftströmungsumlenkabschnitte 5, 6 können Strömungsgeräusche und Strömungswiderstand verringert werden. Der verringerte Strömungswiederstand kann sich günstig auf die Saugleistung auswirken. The inventive separation of the air flow channel 4 and the Luftströmungsumlenkabschnitte 5, 6 flow noise and flow resistance can be reduced. The reduced flow resistance can have a favorable effect on the suction power.
