Definitions

  • the present invention relates to a blowing terminal intended for adjusting the flow rate and the diffusion of an air flow for ventilation installation of premises.
  • Document DE-A-3 634 703 relates to a blowing terminal comprising a tubular duct, one end of which is closed and the other end of which is connected to a source of pressurized air.
  • This duct has one or more circular, radial openings, opposite which is arranged a profiled element forming a deflecting surface for the air flow.
  • the blowing terminal which it concerns, comprising a curved deflecting surface located in the room, in the air outlet zone, so as to present its upper surface on the side of the fluid stream, is characterized in that that it comprises, at the downstream end of the air supply duct, a throttling nozzle comprising two flaps, each of rectangular shape, and articulated at their ends situated upstream around two axes parallel to the axis of the deflecting surface.
  • This arrangement provides, surprisingly, the deflection of the air flow relative to the outlet axis of the duct, this deflection occurring not on the side opposite to that of which the deflecting surface is located, but on the side of the deflecting surface .
  • the useful deflecting surface is arranged tangentially to the air stream leaving the nozzle.
  • the useful deflecting surface completely or partially masks the air stream leaving the nozzle, the angles which the air streams form with the useful deflecting surface, at their impact points on the latter being less than 90 °.
  • the deflecting surface is mounted in an adjustable manner on two supports fixed to the wall into which the air intake duct opens.
  • a cylinder is used, part of the surface of which constitutes the useful deflecting surface.
  • FIGS 1 and 2 show an air duct 2 opening into a room one of the walls of which is designated by the reference 3. Near its downstream end the air supply duct 2 is equipped a throttle nozzle 4 comprising two flaps 5 each of rectangular shape, and articulated around a horizontal axis 6, the two axes 6 being arranged at the upstream ends of the two flaps 5.
  • a throttle nozzle 4 comprising two flaps 5 each of rectangular shape, and articulated around a horizontal axis 6, the two axes 6 being arranged at the upstream ends of the two flaps 5.
  • the wall 3 is equipped, in front of the outlet of the duct 2 with an air deflection surface 7 constituted in the present case by a cylinder.
  • This cylinder is mounted on the wall by means of two legs 8. The position of the cylinder relative to the legs 8 is adjustable using means not shown in the drawing.
  • the lowest generatrix 9 of the cylinder 7 is substantially tangent to the upper part of the air stream leaving the throttle nozzle.
  • the attraction exerted by the cylinder 9 ensures its deflection, on the side of this cylinder. This deflection is carried out completely silently, despite the acceleration that the air flow undergoes at the passage of the throttle nozzle.
  • FIGS 3 and 4 show this terminal in which the deflecting surface 7 occupies two other positions.
  • the cylinder 7 partially masks the outlet of the nozzle 4, while in FIG. 4, it completely masks it.
  • the angles A formed by the different streams of air leaving the throttle nozzle 4, with the tangents of the cylinder 7, at their respective points of impact thereon, are less than 90 °. This characteristic ensures the deviation of the air stream from the side of the useful deflecting surface.
  • the invention brings a great improvement to the existing technique, by providing a terminal of very simple design, in which all the organs are easily accessible, which is advantageous from a point of view of its maintenance, and which has a pleasant aesthetic, and different from the aesthetics of traditional devices whose outlet is always closed by a grid.
  • the deflection surface of the air flow could be constituted not by a cylinder, but by a part in the form of a section of cylindrical or non-cylindrical surface, for example a section of ellipse, without the this goes beyond the scope of the invention.
