Definitions

  • the invention relates to a connecting piece for a Vacuum cleaner for connecting a vacuum cleaner hose with a vacuum cleaner motor housing, one with the motor housing connectable nozzle and one on the nozzle after 90 ° deflection adjoining the outside by means of a deflection part.
  • connecting pieces for vacuum cleaners which an angle of curvature between the nozzle and one Have deflection part from 0 - 90 °.
  • This connector serve as a releasable connecting element between Vacuum cleaner hose and vacuum cleaner motor housing. It are preferred connecting pieces, which with the Form the suction hose as an inseparable unit. The Separation takes place here between the connecting piece and the vacuum cleaner motor housing. Curved connecting pieces, which have a deflection of approximately 90 °, are mostly on vacuum cleaners with overhead air supply used to kink the flexible Prevent hose and ergonomic operation to enable. Connection piece and basic device are often so designed that there is rotation of the suction hose to the basic device.
  • the well-known curved connection piece are integral with one essentially cylindrical flow cross section formed. Production related have these inside the curvature in the flow channel a sharp-edged transition. Any Blockages caused by the sharp-edged transition are promoted in the known prior art especially difficult to remove if this Blockages on the hose-side leg, d. H. in the Area of the deflection part of the curved connection piece occur because this area is very difficult to access is. Furthermore, the sharp-edged transition leads to flow losses.
