Abstract

L'invention porte sur des améliorations apportées à des aspirateurs à double canal. Des aspirateurs à double canal comportent un ensemble de chambres de fluide sensiblement étanches au fluide pourvues d'un canal d'évacuation de fluide ayant un élément de redirection à proximité de sa sortie, et d'un canal d'admission de fluide. L'invention porte également sur un moteur de soufflerie d'aspirateur pour aspirer le fluide dans ledit canal d'admission de fluide. L'élément de redirection est conçu pour renvoyer le fluide expulsé dudit canal d'évacuation de fluide au canal d'admission de fluide de sorte que le fluide renvoyé agite la surface à nettoyer. Une amélioration concerne les chambres de fluide constituées d'un élément supérieur, d'un élément central et d'un élément inférieur, l'élément supérieur et l'élément central formant le canal d'évacuation de fluide, et l'élément central et l'élément inférieur formant le canal d'admission de fluide. Une autre amélioration concerne un générateur d'écoulement qui est destiné soit à créer, soit à compléter l'écoulement de fluide dans le canal d'évacuation de fluide.
