Abstract

L'invention concerne une conduite de sortie d'air d'un aspirateur qui est agencée entre une entrée d'air et une sortie d'air de l'aspirateur. La conduite de sortie d'air est dotée d'une chambre d'alimentation et d'au moins une chambre anéchoïque en communication avec la chambre d'alimentation. Un moteur est agencé dans la chambre d'alimentation. La direction d'écoulement d'air de la chambre d'alimentation et la direction d'écoulement d'air dans la/les chambre(s) anéchoïque(s) sont retournées et modifiées dans un emplacement spatial en trois dimensions. La conduite de sortie d'air est également dotée d'un dispositif déflecteur et l'écoulement d'air du dispositif déflecteur et l'écoulement d'air de la/des chambre(s) anéchoïque(s) entrent en collision mutuelle. La conduite de sortie d'air de l'aspirateur est associée à diverses mesures de réduction du bruit et utilise pleinement l'espace de la chambre de sorte que la plage d'une fréquence d'atténuation du bruit soit étendue et que le bruit de l'ensemble de la machine soit faible et maintenu à un niveau tolérable.
