Definitions

  • This invention relates to a blower for vacuum cleaners, in which a rapidly revolving wheel set with blades or vanes draws in air by suction, and forces it into a dust bag through an-air outlet connection branching ofi radially or tangentially at any convenientangleofinclinationto the plane of rotation of the vane wheel or fan.
  • a blower for vacuum cleaners in which a rapidly revolving wheel set with blades or vanes draws in air by suction, and forces it into a dust bag through an-air outlet connection branching ofi radially or tangentially at any convenientangleofinclinationto the plane of rotation of the vane wheel or fan.
  • the fan or its vane-carrying disc has hitherto been at right angles to the axis of the fan, which has the result thatthe air,flowing away from the fan just at the point of connection to the air outlet branch, enters the inclined connection branch more or less in the direction oi.
  • the object of this invention is to obviate this disadvantage, and for this purpose the invention consists in adapting the shape of the fan to the direction of flow of the escaping air, which is determined by the inclination of the air outlet connection.
  • This is preferably efiected by raising the marginal portion of the fan or of its vanecarrying disc at the same or approximately the same angle of inclination as the air outlet connection.
  • a is the blower casing, with a suction nozzle or brush b exchangeably arranged either directly on the casing or on a separate suction connection, and an air outlet connection 0, which branches off from the casing a at any convenient angle of inclination :c to the plane of rotation of the fan or vane wheel 1.
  • the air outlet branch 0, to which a dust bag, not shown, is directly connected serves at the same time as a handle.
  • the fan consisting of blades 1 secured to a substantially conical disc 9, is mounted upon the shaft e of an electric motor d, and is so arranged with the motor in the casing, that between the fan and the peripheral wall of the casing an air-guiding passage or diffuser 2' is obtained.
  • the diffuser passage may extend parallel to the fan right to the air outlet connection, or else may ascend helically at an angle of inclination which is equal or approximately equal to that of the air outlet connection 0, as shown in Figure 1.
  • the shape of the fan is adapted to the direction of flow of the air discharged thereby, which is determined by the inclination a: of the air outlet branch c.
  • the fan I or its vane-carrying disc g ascends uniformly towards the margin at the same angle of inclination 1:, as shown in Figure 2, or at approximately the same angle, as shown in Figure 1, as the air outlet connection 0, as a result of which the air flowing from the fan directly into the outlet con nection is from the outset directed in a direction of flow which is adapted to the angle of inclination a: of the outlet branch.
  • the ascending portion of the fan disc 9 need not necessarily be rectilinear, as shown in Figures 1 and 2, but may alternatively ascend in a more or less curved line, as shown in Figure 3, or else in steps, as shown in Figure 4.
  • vanes or blades f of the fan on the side opposite to the carrying disc 9, may still extend at right angles to the axis of rotation, as shown in Figures 1, 2, and 3, or else, on this side also, may be inclined upwards and outwards to a greater or less extent, as illustrated in Figure 4, to correspond to the inclination of the carrying disc.
  • a blower for hand vacuum cleaners comprising a casing, a substantially conical blade-carrying disc rotatably mounted in the casing, blades secured to the said disc to form a fan, and an air outlet connection branching ofi from the casing at an angle to the plane of rotation of the fan, the upper boundary of the inclined air outlet connection lying approximately in a continuation of the conical surface of which the blade-carrying disc forms a part.
