Definitions

  • the invention concerns liquid-assisted suction cleaners with a rotating separator.
  • the air drawn in for cleaning is forced into contact with a liquid, generally water, that captures the particles of dust and dirt, the advantage being that, in the absence of a filter, all that is needed is a periodical change of water.
  • the shape of the separator is cylindrical or conical; in its side walls are a number of slits through which the air is drawn in.
  • Subject of the invention is a liquid-assisted suction cleaner with an electric motor operating at high speed.
  • the separator presents a truncated-cone shaped structure formed of a number of radial vanes of a substantially rectanguler cross section, widths and thicknesses decreasing from the greater base, facing towards the electric motor, to the smaller base.
  • the vanes are slightly helical.
  • vanes are joined together by an internal ring placed substantially halfway up their height, flush with their internal walls, and made with them to form a single piece.
  • Diameter of the greater base mm 55.
  • Diameter of the smaller base mm 41.
  • Width of the vanes at the greater base mm 5.
  • Width of the vanes at the lesser base mm 3.
  • Thickness of the vanes at the greater base mm 3.2.
  • Thickness of the vanes at the smaller base mm 1.9
  • the lesser sides of the radial vanes are preferably slightly arched, the radius of the external concavity being approximately mm 200.
  • the separator is preferably made in a single piece of moulded plastic material.
  • the separator is balanced by the presence on its flat external face of a thick ring forming the separator's greater base, as well as by the presence, on the internal face of its flat bottom at the smaller base, of a number of closely-placed circumferential cavities, the depth of each of said cavities being adjusted by screwing up or unscrewing the projecting heads of screw parts present in the die, used for moulding the separator, in order to create said cavities.
  • the separator is preferably fixed to the shaft of the electric motor by a spacer comprising a circular base, with external ribbing, the dimensions of this base corresponding to a circular seat made on the internal wall of the thick ring forming the greater base of the separator.
  • this spacer is a central tubular column, to be applied to the shaft of the electric motor, its end facing towards the smaller base of the separator and matching the outer edge of the circular base of the spacer, with a circular seat on the inner edge of said thick ring.
  • a central tubular column On the bottom of the separator, at its smaller base, is a central tubular column that permits entry and exit of the threaded end of the shaft of the electric motor through a central hole made for the purpose in said bottom of the separator.
  • the separator By screwing a threaded head onto said threaded end, the separator is locked on the drive shaft both at the greater base by means of the spacer, and at the smaller base, to provide maximum protection against vibrations that could be generated when the separator rotates at high speed.
  • the separator is caused to rotate by a longitudinal flat area present at the end of the drive shaft onto which can be fitted both a flat raised area, made at the top of the tubular column of the spacer, as well as a raised area on the inside, and over the whole length, of the hole in the tubular column made in the bottom that forms the smaller base of the separator.
  • the separator is painted with epoxy paint to protect it from the water and to prevent the formation of damp , especially on the surfaces of the vanes, such as would alter both dimensions and weight, with consequent variations in performance and generation of vibrations.
  • Fig. 1 Suction cleaner with electric motor and rotating separator, side view.
  • FIG. 2 As above showing a partial longitudinal section.
  • FIG. 3 An exploded view of the cleaner in Fig. 1.
  • Fig. 4 Spacer for optimum assembly of the separator on the shaft of the electric motor, longitudinal section.
  • Fig. 5 As above, plan view.
  • Fig. 6 Plan view of the separator, seen from outside.
  • Fig. 7 Longitudinal section of the separator at the centre line.
  • Fig. 8 Plan view of the inside of the separator.
  • FIG. 9 Detail of assembly of the separator, with the spacer, on the shaft of the electric motor.
  • the suction cleaner 10 comprises an upper cowling 11, handle 12, motor cover 13 with grill 14 for outflow of cleaned air, the container 16 with a lever clasp 17 to hold the container 16 to the cover 13.
  • Substantially at the top of the container 16 is an air entry mouth 21 connected to the bottom of the container 16 by an S-shaped immersion tube 22 at whose lower end is an outflow mouth at the end of a short curve.
  • the container stands on a trolley 18 with wheels 19.
  • the spacer 32 and separator 40 are fitted on the end of said shaft.
  • the spacer 32 presents a circular annular base 33 with spokes 34 and external rim 38.
  • the separator 40 presents a truncated-cone shaped structure formed of a number of longitudinal helical vanes 41 that give rise to a number of substantially parallel slits, said structure having a greater base 47 and a smaller base 48 ( Figure 6).
  • vanes present a cross section 44 longer and wider than their cross section 43 at the smaller base.
  • each vane 41 is concave in shape roughly corresponding to an arc of a circle ( Figure 7).
  • vanes are connected internally to the separator by a ring 49, the purpose of this being to reduce vibrations in the separator that would otherwise be caused by its high speed of rotation.
  • the smaller base 48 is closed at the bottom 51.
  • Said ring 50 and said bottom 51 respectively present crowns 54 and 55 of small cylindrical cavities 56, 57, at the base of which are the heads of screws prepared in the die that moulds the separator in a single piece.
  • the bottom of said cavities can be adjusted as desired to achieve perfect balance of weights so as to prevent or greatly reduce vibrations caused by the speed of rotation.
  • the separator is assembled as follows ( Figure 9).
  • the separator is then mounted inserting the column 52 on the bottom 51 of said separator, at its smaller base 48, making the flat prominence 53 ( Figure 7) on said column coincide with the flat area at the end 30 of the drive shaft ( Figure 9), as far as entry of the rim 38 on the spacer 32 into the inner annular seat 60 of the annular edge 50 of the separator.
  • the threaded tip 31 of the drive shaft projects from said bottom 51 of the separator where the threaded head 35 can be screwed on.
  • This action by the separator forms a down-flowing column of dust and water which, from the chamber 23, passes on to become mixed with the water in the bottom of the container.
  • the rotatingseparator is coated inside and outside with epoxy paint to protects it from the water and prevent formation of damp, especially on vane surfaces, that would cause variations in dimensions and weights compared with those originally designed, leading to an uneven performance and to generation of vibrations.
