Abstract

Ein Staubsauger (100) umfasst ein zu kühlendes Bauteil (110) und einen Nebenluftkanal (120). Der Nebenluftkanal (120) erstreckt sich in Luftströmungsrichtung von einer Gehäuseöffnung des Staubsaugers über das zu kühlende Bauteil (110) bis zu einem Hauptluftkanal (102) oder bis zu einem Gebläse (104) des Staubsaugers. Ferner weist der Nebenluftkanal (120) luftstromaufwärts von dem zu kühlenden Bauteil (110) eine Verengung (130) auf. Die Verengung (130) ist angeordnet und ausgebildet, sodass im Betrieb des Staubsaugers ein Luftstrom, der durch die Verengung (130) strömt, in Richtung des zu kühlenden Bauteils (110) ausgerichtet ist. Durch die Verengung (130) im Nebenluftkanal (120) können am Austritt der Verengung (130) hohe Luftgeschwindigkeiten erreicht werden. In Kombination mit der Ausrichtung des Luftstroms auf das zu kühlende Bauteil (110) kann eine sehr effiziente Kühlung des zu kühlenden Bauteils (110) erfolgen.

A vacuum cleaner (100) comprises a component to be cooled (110) and a secondary air channel (120). The secondary air channel (120) extends in the air flow direction from a housing opening of the vacuum cleaner via the component to be cooled (110) to a main air channel (102) or to a blower (104) of the vacuum cleaner. Furthermore, the secondary air channel (120) has a constriction (130) upstream of the component (110) to be cooled. The constriction (130) is arranged and designed such that, during operation of the vacuum cleaner, an air flow which flows through the constriction (130) is aligned in the direction of the component (110) to be cooled. By the constriction (130) in the secondary air channel (120) high air velocities can be achieved at the outlet of the constriction (130). In combination with the alignment of the air flow on the component to be cooled (110) can be done very efficient cooling of the component to be cooled (110).
