(EN) VACUUM CLEANER
(FR) ASPIRATEUR
Abstract
(EN) A vacuum cleaner comprises a dirt inlet and a motor and fan for delivering suction to the dirt inlet. A cyclone unit is used for separating particles from a suction flow, having a vortex finder extending along a cyclone axis of rotation and an annular chamber formed around the outside of the vortex finder. The delivery of air to the cyclone unit is in a forward direction (i.e. forward is a direction from the dirt inlet to the cyclone unit). The cyclone axis of rotation is parallel or near to parallel to this forward direction. The outlet from the vortex finder is at a backward end thereof such that outlet from the vortex finder is generally in the opposite direction to the forward component. This means the space beyond the vortex finder can be used as part of the dirt collection area, and this enables more effective collection of hairs and other debris.
(FR) Un aspirateur comprend une entrée de saleté et un moteur et un ventilateur permettant de distribuer une aspiration à l'entrée de saleté. Une unité de cyclone est utilisée pour séparer des particules d'un flux d'aspiration, présentant un diaphragme s'étendant le long d'un axe de rotation de cyclone et une chambre annulaire formée autour de l'extérieur du diaphragme. La distribution d'air à l'unité de cyclone est dans une direction vers l'avant (c'est-à-dire une direction allant de l'entrée de saleté à l'unité de cyclone). L'axe de rotation de cyclone est parallèle ou quasi-parallèle à cette direction vers l'avant. La sortie du diaphragme se situe au niveau d'une extrémité arrière de celui-ci de sorte que la sortie du diaphragme se situe généralement dans la direction opposée à l'élément avant. Cela signifie que l'espace au-delà du diaphragme peut être utilisé en tant que partie de la zone de collecte de saleté, ce qui permet d'obtenir une collecte plus efficace de poils et d'autres débris.
