Abstract

La présente invention concerne une hélice (10) pour appareil soufflant, configurée pour être entraînée en rotation autour d’un axe longitudinal (A), l’hélice comprenant :- une paroi proximale (4) définissant une ouverture d’admission (40) admettant un flux d’air dirigé selon l’axe longitudinal (A),- une pluralité de canaux de passage d’air (3) en communication fluidique avec l’ouverture d’admission (40), lesdits canaux de passage d’air (3) étant positionnés autour de l’axe longitudinal (A), chaque canal de passage d’air (3) s’étendant radialement entre une extrémité d’entrée et une extrémité de sortie, l’extrémité de sortie ayant une section de sortie (34) ayant une dimension maximale parallèlement à l’axe longitudinal (A) supérieure ou égale à 4 millimètres.La présente invention concerne par ailleurs un appareil soufflant, de préférence un sèche-cheveux ou un aspirateur, comprenant une telle hélice.
