Abstract

Saugdüse (12) für einen Staubsauger, mit einem Saugdüsengehäuse (13), welches einen Strömungskanal zur Strömungsverbindung eines Saugmunds (15) mit einem Sauggebläse (5) ausbildet, wobei sich der Querschnitt des Strömungskanals vom Saugmund (15) ausgehend in frontaler Ansicht derart trichterförmig verengt, dass die Längserstreckung (21) des sich trichterförmig verengenden Querschnitts des Strömungskanals im Saugdüsengehäuse (13) in seitlicher Ansicht vom Saugmund (15) ausgehend bogenförmig gekrümmt verläuft.
Durch die bogenförmige Krümmung kann die Bauhöhe der Saugdüse (12) so gering ausgebildet werden, dass sich ein Unterfahren auch niedriger Möbel, beispielsweise von Betten, komfortabel durchführen lässt. Dabei kann der Druckverlust im saugmundseitigen Strömungskanal der Saugdüse (12) gering gehalten werden, so dass die Leistung des Sauggebläses (5) besonders effizient genutzt wird. Auch lässt sich eine gleichmäßige Druckverteilung über die Breite des Saugmunds (15) erzielen.
