Title (EN) A VACUUM CLEANER
(FR) ASPIRATEUR
Abstract:
(EN) A vacuum cleaner (1) comprising: a dust collector housing (13) forming a compartment (14) for collecting dust transported by an air flow generated by a motor assembly (16) located externally of the compartment; an opening (25) in a wall (13a) of the housing for allowing air to flow out of the compartment (14) towards a fan (19) of the motor assembly; and a structure (28, 48, 58) provided upstream of the opening and comprising a solid wall portion (28a, 48a, 58a) providing a sound reflective surface for reflecting sound waves from the motor assembly, the structure (28, 48, 58) being arranged such that a clearance (30) is formed between at least a region of the wall (13a) around the opening and the structure (28, 48, 58) to allow air from upstream of the structure to enter the opening via the clearance (30). A sound absorbing material (29) may be located between the solid wall portion (28a, 48a, 58a) and the fan (19).
(FR) L'invention concerne un aspirateur (1) comprenant : un boîtier de collecteur de poussière (13) formant un compartiment (14) pour collecter la poussière transportée par un flux d'air généré par un ensemble moteur (16) situé à l'extérieur du compartiment ; une ouverture (25) dans une paroi (13a) du boîtier pour permettre à l'air de s'écouler hors du compartiment (14) vers un ventilateur (19) de l'ensemble moteur ; et une structure (28, 48, 58) disposée en amont de l'ouverture et comprenant une partie de paroi solide (28a, 48a, 58a) fournissant une surface de réflexion sonore pour réfléchir des ondes sonores provenant de l'ensemble moteur, la structure (28, 48, 58) étant disposée de telle sorte qu'un espace libre (30) est formé entre au moins une région de la paroi (13a) autour de l'ouverture et la structure (28, 48, 58) pour permettre à l'air provenant de l'amont de la structure d'entrer dans l'ouverture par l'intermédiaire de l'espace libre (30). Un matériau absorbant le son (29) peut être situé entre la partie de paroi solide (28a, 48a, 58a) et le ventilateur (19).
