Definitions

  • FIGURE 13 is a partial plan view of a vacuum cleaner showing a modification with respect to that of FIGURES 1 to 4;
  • the forward extremities of the arms 33 co-operate with leaves 35 at either side of the casing 1 which are articulated to lugs 36 rigid with tray 24, so that the handle 31 can be used to control opening of the tray.
  • the rear ends 37 of the levers 35 which are downwardly bent, engage in notches 38 at the extremities of the arms.
  • the lugs 36 extend upwardly.
  • the lever ends 37 being caught in the notches 38, are displaced rearwardly and rotate the lugs 36, which bring the tray 24 with them.
  • To return the tray 24 to closed condition the handle 31 is moved back to its operating position whereupon the levers 35 cause the tray to move correspondingly.
  • the tray 24 can thus be emptied without touching it.
  • a blower for a domestic vacuum cleaner is necessarily a flow machine operating at low Reynolds numbers.
  • low Reynolds numbers have been associated with unavoidable inefliciency.
  • this blower is able to show unexpectedly high efliciencies and in consequence, for a corresponding performance a blower constructed on the principles described above will be smaller and lighter than a comparable axial or centrifugal blower of conventional design.
  • FIGURE 18 In the FIGURE 18 arrangement the configuration of the flow guiding surfaces is generally similar to that of FIGURE 4, and the main guide surface is the surface 160: the FIGURE 19 arrangement is different and the main guide surface is the curled tip 157 of the body 158.
  • the FIGURE 18 arrangement produces a bigger vortex produces less throughput. The construction may thus be used normally in the FIGURE 18 arrangement, and the body 158 moved to the FIG- URE 19 position when the character of the surface to be cleaned requires extra throughput.
  • FIGURES 23, 24 and 24a illustrate a further modification of the vacuum cleaner of FIGURES 1 to 3. It is to be assumed that the modified blower of FIGURES 23 and 24 is incorporated in FIGURES 1 to 3 in place of the FIGURE 4 blower, without other modifications. Parts in FIGURES 23 and 24 which correspond with parts of the FIGURE 4 blower are given the same references and will need no further description.
  • FIGURE 24a illustrates the operation of what has been described with reference to FIGURES 23 and 24.
  • a vacuum cleaner as claimed in claim 9 wherein said tray is pivotally connected at one end to said vacuum cleaner whereby its other free end may move between dust-catching and dust-releasing positions.
