Definitions

  • the invention relates to a universal brush for a vacuum cleaner according to the preamble of claim 1.
  • Universal brushes of this type have an elongated brush housing, in the underside of which there is a central suction slot. When vacuuming a surface, the bristles of the universal brush loosen and whirl up the dust or dirt to be removed, whereupon the loose particles are to be absorbed into the suction slot of the brush.
  • the bristles in the previously known universal brushes are arranged in individual bristle groups around the suction slot.
  • dust and dirt are whirled up in front of the bristle groups located in the advancing direction of the universal brush and arranged in front of the suction slot and swept in front of the bristles.
  • the particles In order to be sucked in through the suction slot, the particles must first pass through the row of bristles. The result of this is that the bristles are relatively quickly clogged by the detached particles, in particular larger lint, as a result of which the cleaning performance of the brush, which is unsatisfactory even when the bristles are in an unimpaired state, drops further.
  • the present invention has for its object to develop a universal brush of the type under consideration so that the dust and dirt pickup is significantly improved.
  • the bristles are not arranged at the edge of the suction slot, but rather exactly in the middle thereof.
  • the bristles thus extend out of the suction slot along the longitudinal axis.
  • the universal brush according to the invention thus ensures a high degree of dust and dirt absorption, lint and similar larger particles also being released quickly and reliably and can be sucked in. In contrast to the previously known universal brushes, dust pollution of the surroundings of the documents to be cleaned is practically completely avoided.
  • the bristles are arranged in the form of a continuous bristle strip.
  • a completely uniform processing of the substrate is thus achieved over the entire length of the bristle strip, with the result that, for example, the formation of stripes due to locally varying intensity of brushing is avoided.
  • the continuous bristle strip also largely prevents the deposit of larger particles such as lint and the like in the bristle area, so that frequent cleaning of the bristles is unnecessary.
  • a holder for the bristles is expediently fitted within the brush housing.
  • This holder can be integrally formed on the brush housing at the front and rear end of the suction slot and can be penetrated by a vertically extending opening.
  • the bristle ends can first be accommodated in a metal frame which is inserted into the holder, where it can be held in friction against the stops provided for this purpose.
  • the brush housing consists of two horizontally divided housing parts which are attached to one another by suitable means.
  • This design has the advantage that the bristle strip with the metal frame can be inserted into the holder from above, which simplifies the assembly of the universal brush according to the invention.
  • the brush housing has a nozzle-shaped cross section in the region of the suction slot. If, in this embodiment, the bristles bend in the direction facing away from the feed direction of the universal brush when processing a base, they lie against the leg there, so that the suction cross section lying on the feed side is wide open.
  • the universal brush for example as a furniture brush
  • the mobility can be achieved for example by spherical mounting of the suction flange in the brush housing.
  • the brush housing 1 of the universal brush consists of two horizontally divided housing parts 2 and 3.
  • a flange 4 is formed, which is plugged onto the suction pipe, not shown, of a vacuum cleaner.
  • a continuous bristle strip 5 can be seen on the underside of the brush housing 1, which extends essentially over the entire length of the brush housing 1.
  • Front legs 6 of the lower housing part 3 run towards each other at an angle to the underside of the housing part.
  • the bristle strip 5 is fastened inside the brush housing 1.
  • a holder 7 is formed on the front and rear end of the lower housing part 3.
  • a vertical opening extends through the holder 7.
  • the upper end section of the bristle strip 5 is received in a metal frame 8, which holds the bristle strip 5 in a press fit.
  • the bristle strip 5 is inserted with the metal frame 8 into the holder 7 from above until the metal frame 8 bears against stops 9 of the holder 7.
  • the metal frame 8 is held in the inserted position by friction.
  • the bristle strip 5 emerges from the lower housing part 3 in the middle, ie along the longitudinal axis of a suction slot 10, on both sides of the bristle strip 5 a free suction cross section remains.
  • the suction slot 10 extends essentially over the entire length of the lower housing part 3.
  • the lower legs 11 of the lower housing part 3, which extend in the longitudinal direction of the universal brush, are fed at an angle to the bristle strip 5, so that a nozzle-shaped cross section is formed in the area of the suction slot 10.
