Title
(EN) A CYCLONIC SEPARATING APPARATUS WITH ELECTROSTATIC FILTER
(FR) APPAREIL DE SÉPARATION CYCLONIQUE AVEC FILTRE ÉLECTROSTATIQUE
Abstract
(EN)
The present invention relates to a separating apparatus for separating particles from a fluid flow. Particularly, but not exclusively, the invention relates to a domestic vacuum cleaner having such a separating apparatus for removing dust particles from a dust laden airstream. The separating apparatus comprises a first cyclonic cleaning stage comprising at least one cyclone, and an electrostatic filter, wherein the electrostatic filter is in fluid communication with the at least one cyclone via an air passage, at least a portion of the air passage being formed longitudinally through the separating apparatus, wherein at least a portion of the first cyclonic cleaning stage, the electrostatic filter and the air passage are arranged concentrically.
(FR)
La présente invention concerne un appareil de séparation destiné à séparer des particules d'un écoulement de fluide. Plus particulièrement, mais non exclusivement, l'invention porte sur un aspirateur ménager doté d'un tel appareil de séparation destiné à retirer des particules de poussières d'un courant d'air chargé de poussières. Ledit appareil de séparation comprend un premier étage de nettoyage cyclonique qui comporte au moins un cyclone, et un filtre électrostatique qui est en communication fluidique avec le ou les cyclones via un conduit d'air. Au moins une partie du conduit d'air est formée longitudinalement à travers l'appareil de séparation. Le premier étage de nettoyage cyclonique, le filtre électrostatique et le conduit d'air sont disposés au moins en partie de manière concentrique.
