Definitions

  • This invention relates generally to a vacuum cleaner, and more particularly to a portable vacuum cleaner which is constructed to generate a cyclone inside the tank of the vacuum cleaner.
  • Sol er et al . U.S. Patent No. 5,267,371, discloses a cyclonic back pack vacuum cleaner.
  • This patent includes upper and lower casings, and at least one cyclone having a lower part and an air exit port being mounted with the lower part positioned within said lower casing. It also includes a structural limitation that the fan is positioned within the upper casing.
  • Stevenson U.S. Patent No. 5,248,323, discloses a cyclonic back pack vacuum cleaner providing an activated charcoal layer.
  • U.S. Patent No. 5,135,552 discloses a vacuum cleaner having a pair of filters, the first being non- cyclonic, and the second one being cyclonic, with the dust from both filters being deposited m a common reservoir.
  • U.S. Patent No. 4,944,780 discloses a cyclonic -separator type central vacuum cleaner having an in-line configuration.
  • references can be categorized for comparison to the present invention as follows: (a) devices having an air entry means providing an air flow path from outside the vacuum cleaner into a cyclone typically defined by a physical barrier having a generally conical shape. See Soler et al . , Finke, Stevenson , Dyson and Farl ey; (b) devices having an air entry means providing an air flow path from outside the vacuum cleaner to a cyclone defined by a physical barrier having a cylindrical shape contained within a cylindrical container. See Usmani ; and (c) systems having an air entry means providing an air flow path from outside the vacuum cleaner into cyclonic separator comprised simply of the outside wall of the cylindrical container in which the apparatus is contained. See Wei stra .
  • the means for creating the cyclone which serves to separate heavier particles from lighter particles, involves the manufacture and assembly of fairly elaborate pieces and parts having relatively complex shapes and tolerances.
  • the filtration systems of the various devices can be categorized as follows: (a) devices having filters following the cyclone in sequence. See Sol er et al . , Usmani , Stevenson, Dyson, Farl ey and Finke; and (b) systems which employ pre-filtration systems. See Wei stra .
  • a cyclonic vacuum cleaner which employs means for creating the cyclone which is simple in design and easy to manufacture, yet serves effectively for the intended purpose, namely, removal of large particulate matter from the air flow prior to introduction of the air flow through a filter or series of filters.
  • a cyclonic vacuum cleaner having a primary reservoir mto which air is drawn by a fan driven by a fan motor. Air enters the primary reservoir through an air intake, where it is drawn into a cyclone tube. There exists a relationship between the diameter of the cyclone tube and the height of the primary reservoir. In order for the invention to function as described, the height of the primary reservoir should be at a minimum three times the diameter of the cyclone tube and optimally, there should exist at least a five to one ratio between the diameter cf the cyclone tube and the height of the primary reservoir.
  • Air introduced into the cyclone tube exhausts through an open end into the primary reservoir.
  • the cyclone tube itself has a generally circular configuration opening to the air intake on one end and exhausting mto the primary reservoir on the second end. As the air exhausts from the cyclone tube, it is drawn against the side wall of the primary reservoir, swirling around and down the inside chamber of the reservoir, creatmg a cyclone.
  • Air is drawn up through the center of the cyclone through a wet and dry filter into a riser intake. As the air is drawn through the riser intake into the riser, it leaves the primary reservoir and enters a secondary reservoir through the secondary reservoir air intake. At the top end of the secondary reservoir there is a filter housmg holding a bag filter through which the air is drawn. Following the bag filter is a H.E.P.A. filter.
  • Sound generated by operation of the vacuum cleaner is depressed by means of a sound defuser at the air outlet and below the fan and motor housmg.
  • the cyclonic vacuum cleaner may be supported and transported by wheels operatively connected to the cyclonic vacuum cleaner or in the alternative may be transported by means of a shoulder strap or a pair of shoulder straps attached to the cyclonic vacuum cleaner for.

Abstract

Aspirateur (10) à cyclone qui possède un réservoir primaire (14) dans lequel de l'air est aspiré par un ventilateur (36), passe par une entrée d'air (12) et est acheminé dans un tube à cyclone (16). L'air entré sort par une extrémité ouverte du tube à cyclone (16) et pénètre dans le réservoir primaire (14) où il est projeté contre la paroi interne dudit réservoir (14), créant un cyclone. De l'air est aspiré par le centre du cyclone à travers un filtre (18) semi-humide dans une entrée (20) de colonne montante. L'air est aspiré dans la colonne montante (22) et entre dans un boîtier (30) de filtre portant un filtre (32) sous forme de sac et un filtre absolu (34). L'air est évacué de l'appareil par un orifice de sortie (40) d'air qui suit le passage à travers le filtre absolu (34).
