Abstract

Dargestellt und beschrieben ist ein Rohrsystem (1) für einen Staubsauger, mit einem Hüllaußenrohr (2) und einem Sauginnenrohr (3), wobei das Sauginnenrohr (3) einen geringeren Querschnitt als das Hüllaußenrohr (2) aufweist, so dass das Hüllaußenrohr (2) und das Sauginnenrohr (3) mindestens einen Hüllkanal (4) bilden. Ein Rohrsystem (1) das den Verlust von Saugkraft durch das Ansaugen von Nebenluft reduziert und eine ausreichend hohe Stabilität bietet, wird dadurch realisiert, dass an der Außenseite (5) des Sauginnenrohrs (3) radiale Stege (6) ausgebildet sind, durch die das Sauginnenrohr (3) vom Hüllaußenrohr (2) beabstandet ist und dass der Hüllkanal (4) durch die radialen Stege (6) segmentiert ist.
