Definitions

  • a suction cleaning device of the construction described is off EP-B 0 338 780 known.
  • the roller is equipped from flexible lips. Because of the better cleaning effect become bristle-shaped cutlery in practice prefers.
  • a suction cleaning device is known, the a Pelton turbine driven by the suction air flow and a roller driven by the Pelton turbine with bristle-shaped Has cutlery.
  • the bristles of the rollers extends through the one arranged on the underside of the roller chamber Suction mouth.
  • the turbine is as Pelton wheel trained.
  • Other versions such as those for Example from DE-C 41 05 336 are known, have as Cross-flow turbine trained turbine wheel with a open blading on the inside.
  • the cross-flow turbine is flowed essentially radially.
  • the air enters radially the one in the center of the ring-shaped blading Interior of the turbine wheel and radially exits the interior.
  • the cross-flow turbine has one favorable efficiency, but is proportional due to the design prone to dirt and loud. Small parts, for example Paper, paper clips, woolen threads and the like can cause interference at the cross-flow turbine.
  • the Turbine should work quietly, with a low pressure drop cause the suction air flow and at a high Turbine efficiency a favorable turbine efficiency exhibit.
  • the brush roller must be on the turbine unit be coordinated with both low-pile and Suction cleaning is also effective for deep-pile carpets support.
  • the vacuum cleaner be able to hold small parts, such as paper clips, Absorb paper scraps and threads without a malfunction is to be feared.
  • the well-known suction cleaning devices still meet all of these requirements not to the extent desired.
  • the invention has for its object a low-noise, to specify powerful suction cleaning device with which can easily be vacuumed even small parts.
  • the vacuum cleaner for a powerful Vacuum cleaner which has a large volume flow and Suction mouth creates a large vacuum
  • the bristles are cut within the characteristic 1.1) specified parameter range slightly on the Underside of the suction mouth protrudes.
  • the above bristle fulfills an additional support function on the ground.
  • the bristles are not on the bottom of the suction mouth.
  • Compliance with the characteristic 1.2) is essential for effective removal the dirt particles carried in the air flow. Will the The removal value falls below the limit value according to the invention the dirt particles from air turbulence and superimposed Currents from the rotating bristle roller generated, disturbed. Is essential finally, compliance with feature 1.3).
  • the volume ratio is preferably the turbine chamber to that of the material the volume occupied by the turbine in the range from 6: 1 to 8.5; 1. It is also advantageous if the turbine is in the Essentially over the entire width of the preferred cylindrical turbine chamber extends.
  • Suction cleaning device is characterized by exceptional good suction properties combined with a low Noise development.
  • the properties are the result a clever combination of features. Already that Modification of a single characteristic worsens it Result clear. So the effects described are in a complex interrelation.
  • tuning can be the suction properties still optimize. So should the passage to the turbine chamber a rectangular exit cross-section with a width of 10 to 18 millimeters and a height of 14 up to 18 millimeters.
  • the distance between the axes of rotation the roller and the turbine is expediently 70 up to 90 millimeters.
  • the suction properties of the vacuum cleaning device can also be influenced favorably if the roller is arranged off-center to the suction mouth.
  • Suction cleaning device include a suction head 1, the one has suction mouth delimited on the bottom by suction mouth edges 2, a turbine 3 in driven by the suction air flow a turbine chamber 4 of the suction head, one helical roller 6 with bristles 5, which is in a roller chamber 7 of the suction head 1 and driven by the turbine 3 is, the roller chamber 7 with the turbine chamber 4 connecting passage 8 and a to the turbine chamber 4th Exhaust duct 9 connected in a tiltable manner with a connecting piece 10 for a suction pipe.
  • the turbine 3 is as Pelton wheel formed and essentially tangential from the suction air stream emerging from the passage 8 flows against.
  • Bushings and mutually movable parts of the in the suction cleaning device shown in the figures are useful sealed in such a way that the following industry standard test procedures a pressure drop from 65 to 80 mbar.
  • Vacuum connected which is operated so that it when the suction port is closed, a pressure reduction against Atmospheric pressure of 100 mbar generated.
  • the so set The vacuum cleaner is then connected to the vacuum cleaning device to be tested connected, its suction mouth sealed with a film is taped.
  • the one on the suction side of the suction cup Pressure is measured.
  • the suction cleaning device meets the requirement of the invention when there is a pressure drop of at least 60 mbar, preferably from 60 to 90 mbar, set against atmospheric pressure.
  • the suction cleaning device with the parameter adjustment according to the invention is characterized by exceptionally good Suction properties in connection with a low noise level out.
