Definitions

  • the invention relates to a upholstery nozzle in which a thread lifter is arranged on at least one working edge of the nozzle housing according to the preamble of claim 1, as described for example in DE 1 030 979.
  • the invention has for its object to provide a cushion nozzle of the type described above so that despite a structural reduction of the upholstery better or at least as good cleaning effect is achieved.
  • the stated object is achieved by a upholstery nozzle according to claim 1. Since only one working edge a thread lifter is attached, also needs only this working edge to be made correspondingly wide. The width of the other working edge, however, can be reduced to the wall thickness of the nozzle housing.
  • the fibers picked up by the thread lifter from the surface to be cleaned and stripped in the reversal of the direction of movement of the upholstery nozzle are detected by the air flowing in via the air inlet openings and entrained in the suction direction. In this way it is prevented that the fibers once dissolved are pressed by the other working edge back to the surface to be cleaned.
  • only one thread lifter at least as good cleaning effect as with an arrangement of two thread lift achieved.
  • a reduction in fiber absorption when sinking the working edges of the upholstery in the material of an object to be cleaned is counteracted that the air inlet openings are at least partially raised so far in their position relative to the respective working edge or wegher far away in the vertical direction of the working edge that through that takes place during a cleaning process sinking of the working edge in the surface of an object to be cleaned no complete overlap of the air inlet openings by the material of the surface.
  • a padding nozzle 1 is referred to, at the front working edge 2 in the working direction of an existing Schrägborstenstoff thread lifter 3 is arranged.
  • a plurality of slot-shaped air inlet openings 5 are provided on the nozzle housing 6 of the upholstery nozzle 1. These air inlet openings 5 can be arranged at different altitudes with respect to the rear working edge 4. This ensures that the suction of a soft surface or a surface with a long pile, the air inlet openings 5 when sinking the working edges 2 and 4 in the surface to be cleaned by the soft surface or the pile are not covered so far that no more air over the Air inlet openings 5 can flow.
  • the air inlet openings 5 extend in the vertical direction relative to the working edge 4 so far upwards that a complete coverage and thus closing the air inlet openings 5 is avoided when sinking the working edge 4 in the surface to be cleaned by the material of the surface or by the pile of a cushion or carpet surface in any case. This leaves at least one residual gap of the air inlet openings 5 free, can flow through the air into the interior of the nozzle housing.
  • the bristle direction of the Schrägborstenschers the thread lifter 3 is chosen so that in a forward movement of the upholstery nozzle 1 in the direction of the front working edge 2, the previously recorded in the reverse direction of movement of the thread lifter 3 fibers are stripped from the thread lifter 3. These stripped fibers are entrained and transported away by the air flowing in via the air inlet openings 5 in the direction of the connection pipe 7 of the upholstery nozzle 1 coupled to a suction pipe connected to a vacuum cleaner. This prevents that these once dissolved fibers are pressed by the rear working edge 4 back to the surface to be cleaned, which would lead to a deterioration of the cleaning result of the upholstery 1.
