Definitions

  • the invention relates to the field of household appliances vacuum cleaners and more particularly sleigh vacuums including rigid tubes equipping such vacuum cleaners.
  • these vacuum cleaners generally comprise a frame mounted on wheels for its movement on the ground.
  • This frame contains a motor-fan for creating a suction flow, and a device for separating waste, either by a filter membrane, or by a device called “bagless”, inertia separation, or any device equivalent.
  • the frame of such vacuum cleaners is connected to a suction nozzle, such as a nozzle, by different conduits, generally comprising a rigid conduit in connection with the nozzle, and a flexible conduit connecting the rigid conduit to the frame, and facilitating the handling of the nozzle.
  • the storage of such vacuum cleaner is most often to arrange the rigid conduit vertically along one of the walls of the frame, by a suitable slide.
  • the length of the rigid ducts causes a congestion which remains important.
  • an aspirator comprising two telescopic tubes, the inner tube having fingerprints for housing a locking member mounted on a control carried by the outer tube, to adjust the final length presented by the two tubes.
  • the indentations in the inner tube made by local stamping of the tube, leave a rugged surface inside the inner tube, which causes flow disturbances of the suction flow, generating in particular noise.
  • the present invention therefore aims to present a device of telescopic tubes particularly quiet, without reducing the ease of use of such arrangements.
  • Another object of the invention is to improve the storage of the vacuum cleaners.
  • the present invention is achieved by means of telescopic tubes for suction duct of a vacuum cleaner having two tubes, the inner tube carrying a notched strip on its outer surface, the outer tube comprising a locking member capable of interacting with the notches of the ruler of the inner tube, the inner tube having a recess for housing the toothed ruler, characterized in that the inner tube comprises means for deflecting the flow of air in order to reduce the turbulence at the level of the imprint .
  • the present invention thus aims to reduce the turbulence generated by the imprint formed in the air circulation tube. This reduction in turbulence makes it possible to fluidize the flow, which reduces the aeraulic noise at the passage of this change of section.
  • the means for reducing turbulence at the level of the cavity consist of a bevel formed on the front end of the cavity of the inner tube.
  • the footprint making a recess in the inner section of the air flow tube it should be made softer such a recess to make it as quiet as possible.
  • the angle of the bevel with the axis of the tube is less than 30 °, so as not to present a frontal area too abrupt.
  • At least a portion of the bevel comes from an insert on the inner tube.
  • the front end of the bevel is shaped transversely in a circular arc, which also allows sideways deflection smoothly part of the air flow, and also avoids a frontal shock wave to the passage of the footprint.
  • the value of the radius of the arc is at least equal to the half width of the cavity.
  • the means for reducing turbulence at the level of the impression consist of a covering of the impression in the inner tube by a part covering the impression along a longitudinal plane parallel to the axis of the tube.
  • the trim piece extends transversely to the edge of the tube.
  • the inner surface of the tube is thus completely smooth, which promotes a fluid flow.
  • the trim piece is connected to a beveled piece at its front end so as not to create a frontal impact with the sucked air.
  • At least a portion of the beveled piece comes from an insert on the inner tube.
  • This variant finds its interest when the piece in question has another feature, since it then plays two distinct roles.
  • this part can be a sealing ring with the outer tube.
  • Such a piece thus extends from the inner tube to the outer tube by a frustoconical shape, a peripheral collar slightly in contact with the outer tube for sealing.
  • this part comprises a portion of the bevel as defined above, the fluidic connection between the outer tube and the inner tube is improved, since possible recesses linked to separate parts are thus avoided.
  • the beveled piece comes from the piece dressing. This embodiment is facilitated when the piece is from molding.
  • the present invention also aims to protect a vacuum cleaner comprising a body, inside which is housed a motor-fan and a waste separation device, the body being connected to a suction nozzle through a suction pipe comprising at least one rigid pipe at the end of which is disposed the suction nozzle, characterized in that a portion of the rigid conduit is an assembly of telescopic tubes according to one of the characteristics mentioned above.
  • the rigid conduit has a hinge substantially mid-length of the conduit, allowing a rotation of about 180 ° of a portion of the conduit relative to the other portion, the rotation being carried out in a plane parallel to the axis tubes.
  • a sealing means is disposed between the two duct portions, the hinge being associated with a locking device of the two duct portions by abutment of said portions.
