Title
(EN) VACUUM CLEANER
(FR) ASPIRATEUR
Abstract
(EN)
A vacuum cleaner includes a suction inlet, a suction source configured to generate an airflow through the suction inlet to draw debris with the airflow through the suction inlet, and a separator assembly. The separator assembly includes a housing having an air inlet and an air outlet, a debris collection chamber within the housing, and an inner chamber formed within a shroud that defines a cyclone axis and has a perforated portion. The inner chamber has a first end and a second end. The first end has a tangential inlet. The second end is open toward the debris collection chamber. An outflow passageway is outside of the shroud and in fluid communication with the air outlet and a filter is in fluid communication with the outflow passageway. The first end of the inner chamber is positioned between the air outlet and the second end of the inner chamber.

L'invention concerne un aspirateur qui comprend une entrée d'aspiration, une source d'aspiration conçue pour générer un flux d'air à travers l'entrée d'aspiration pour aspirer des débris avec le flux d'air à travers l'entrée d'aspiration, et un ensemble séparateur. L'ensemble séparateur comprend un boîtier comportant une entrée d'air et une sortie d'air, une chambre de collecte de débris à l'intérieur du boîtier, et une chambre interne formée à l'intérieur d'un épaulement qui définit un axe de cyclone et possède une partie perforée. La chambre interne possède une première extrémité et une seconde extrémité. La première extrémité présente une entrée tangentielle. La seconde extrémité est ouverte vers la chambre de collecte de débris. Un passage de flux sortant se trouve à l'extérieur de l'épaulement et est en communication fluidique avec la sortie d'air et un filtre est en communication fluidique avec le passage de flux sortant. La première extrémité de la chambre interne est positionnée entre la sortie d'air et la seconde extrémité de la chambre interne.
