Le fonctionnement de l'aspirateur 2 va maintenant être décrit. Lorsque le moto-ventilateur 13 est alimenté électriquement, il établit une dépression notamment dans le dispositif de séparation de déchets 5 de telle sorte que de l'air et des déchets sont aspirés par le conduit d'aspiration 18. L'air chargé de déchets pénètre ensuite dans le récipient de stockage de déchets 7 via l'ouverture d'admission d'air 9 qui peut par exemple déboucher tangentiellement dans le récipient de stockage de déchets 7. L'air est ainsi mis en rotation et les déchets sont centrifugés vers l'extérieur et ces déchets sont collectés par le récipient de stockage de déchets 7.The operation of the vacuum cleaner 2 will now be described. When the motor-driven fan 13 is electrically powered, it establishes a vacuum in particular in the waste separation device 5 so that air and waste are sucked through the suction duct 18. The air laden with waste then enters the waste storage container 7 via the air intake opening 9 which may for example open tangentially into the waste storage container 7. The air is thus rotated and the waste is centrifuged towards outside and this waste is collected by the waste storage container 7.

Le flux d'air s'écoule ensuite successivement à travers l'orifice de sortie d'air 11, la tubulure de liaison 16, et l'orifice d'entrée d'air 14 et l'orifice de refoulement d'air 15 du moteur d'aspiration 6. Puis, le flux d'air est diffusé radialement vers le filtre 26 par les ouvertures latérales 24, et s'écoule à travers la partie de filtration 27 avant de s'échapper hors du boîtier 3 au travers des ouvertures d'évacuation d'air 28.The air flow then flows successively through the air outlet port 11, the connecting pipe 16, and the air inlet port 14 and the air discharge port 15 of the suction motor 6. Then, the air flow is diffused radially towards the filter 26 through the side openings 24, and flows through the filtration part 27 before escaping out of the housing 3 through the openings exhaust air 28.

Bien entendu, la présente invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the present invention is in no way limited to the embodiment described and illustrated which has been given only by way of example.
