Abstract

L'invention vise à rendre un collecteur de poussière compact par réduction de la dimension verticale de celui-ci. A cet effet, l'invention porte sur un collecteur de poussière (1), lequel collecteur comprend : un réservoir cylindrique (5) qui forme un cyclone principal pour amener de l'air ayant été aspiré vers l'intérieur à partir d'une ouverture d'aspiration (9) à tourbillonner le long de la surface périphérique interne du réservoir (5) ; et un corps (6) qui est installé au-dessus du réservoir (5), qui a un moteur (12) installé à l'intérieur du corps (6) et qui comporte un ventilateur d'aspiration (14) disposé sur l'arbre de sortie (13) du moteur, et qui comporte une ouverture d'aspiration (16) débouchant sur l'intérieur du réservoir (5). De la poussière séparée à l'intérieur du réservoir (5) par le tourbillonnement d'air est confinée à l'intérieur du réservoir (5). De petits cyclones (23, 23,...) sont disposés dans la direction circonférentielle sur une plaque de séparation (21) pour séparer le réservoir (5) et le corps (6). Le moteur (12) est disposé à l'intérieur du groupement des petits cyclones (23) en une position dans laquelle le ventilateur d'aspiration (14) fait saillie dans le réservoir (5), et le ventilateur d'aspiration (14) est amené à chevaucher les petits cyclones (23) dans la direction radiale du réservoir (5).
