Definitions

  • This ⁇ invention relates to avacuum cleaner .with an outer casing, a. motor fan unit arranged therein, an indiarubber ring, arranged in the outer casing in front of the motor fan unit, against' which ring the motor fan unit bears, and a removable' cap, which closes the outer casing at its rear end.
  • the object of the present invention is to improve this known structure in such a way as to provide a particularly simple method of supporti ing the motor fan unit, so as to enable this unit to be quickly and conveniently put in or taken out.
  • the removable cap that closes the outer casing at the rear end is of such concave shape that it directly forms an abutment for the rear end of the motor fan unit.
  • the motor fan unit f which bears loosely at its front end against an indiarubber ring g mounted in the vacuum cleaner casing.
  • an indiarubber ring g mounted in the vacuum cleaner casing.
  • a dust bag his provided in the outer casing of the vacuum cleaner.
  • the part d of the rear closure cap is ⁇ made of insulating material, an artificial resin for example, and is secured in a readily detachable manner by means of a number of screws i arranged on itsperiphery to a metal ring k, which 'in itsjturn is arranged'upon the body a "of the casing.
  • the part d carries a sheet metal insertion m, which is dished insuch'a way as to format the same time the rear abutment n for the motor fan unit, a cavity o for the accommodation of a supplementaryfllter p, q, p' removable at the rear, and a tubular element r for mounting a cover s provided with' a discharge v aperture e.
  • the abutment n has a central aperture w for accommodating the rear end t of the motor i'anunit, and is also provided with apertures u. for the passage of air; The arrowsindicate the direction oi' flow of the air.
  • the supplementar'y filter consists of a thickglayer 'q ot 5 filtering material, made of wadding tor instance,
  • c'avity o to hold and stiflen the layer of filtering material.
  • the cap d, m, r, n may be made entirely of sheet metal.
  • the front sieve plate p may be replaced'by a ring hearing on the outer mai-gin of the layer of filtering material, or may be entireiy omitted.
  • the frustoconical portion n is preferably so shaped as to form at the mai-gin an annular flange supporting the layer of filtering material.
  • the simple marginal supporting of the'actual filtering layer is suflicient, having regard to the pressure exerted. by the air upon the filtering layer when the vacuum cleaner is in operation to press the filtering layer against the rear supporting sieve p'.
  • This 'last-named sieve or periorated plate may be fixedly mounted on the supporting bolts v and may then be taken' ofi' or put on along with the cover s.
  • An important feature isthe sub-dividing 'of the filter into the filtering layer, removable by itself, and capable of being cheaply manufactured.
  • the wadding enables the .filter to absorb a large amount of disinfectant or the like, thus giving Satisfactory and eiiective filtering over a long period. besides considerably improving the clamping of noise.
  • a v'acuum cleaner comprisng an outer casing. a motor fan unit enclosed in the outer casing, an indiarubber ring lodg ed in the outer casing in front of the motor fan unit, the motor tan unit hearing against the indiarubber ring, and a detachable cap ciosing the casing at the rear end, the detachable cap being or such concave shape as to Iorm'directly an abutment hearing against
