Definitions

  • the field of the invention is that of the fumistery in general.
  • the invention relates to a protection device for preventing the wind from discharging fumes and / or combustion gases inside an exhaust duct. It also relates to a hat suitable for wearing this device.
  • the invention applies to flues, stove, or boiler, and more generally to any exhaust pipe or smoke extraction opening to the outside.
  • a cap 10 has been fitted with a substantially cylindrical skirt 11 on its periphery so as to guide the wind inside this cap 10.
  • the circulation of the wind inside the cap creates a constriction of the flow of fumes producing a Venturi effect on the fumes. These are sucked towards an annular opening 13 located under the lid 14 of the cap.
  • a disadvantage of this technique is that in the absence of wind, the suction effect of fumes disappears, and the efficiency of the draft of the chimney is greatly reduced, given the small section of the opening 13.
  • Dynamic suction techniques are also known, using an electric fan covering the exhaust duct.
  • Another known technique is to use a rotary turbine powered by the force of the wind.
  • the invention therefore particularly aims to overcome the disadvantages of the prior art mentioned above.
  • the invention aims to provide a technique for protecting a flue against the effects of wind and / or rain, which is reliable and does not require maintenance.
  • An object of the invention is particularly, in at least one particular embodiment of the invention, to provide such a technique that does not require disassembly to ensure the maintenance of the conduit.
  • An object of the invention is also to provide such a technique which is simple to implement.
  • Another object of the invention is to provide such a technique which is of a reduced cost.
  • Yet another object of the invention is to propose such a technique which accelerates the dispersion of the fumes at the outlet of the duct.
  • Another object of the invention is to provide such a technique that prevents the birds from entering the conduit and to land near or on the conduit, for example to nest and / or peck on the cap of the conduit , in order to eliminate the nuisance caused by noise and faeces.
  • a device for protecting the outlet of a flue gas duct comprising at least a substantially vertical wind screen.
  • substantially vertical means that the screen can be inclined up to 45 ° with respect to the vertical direction.
  • such a device comprises means for driving said screen in rotation around the outlet section of said duct, so as to orient said screen facing the wind.
  • the invention proposes to protect the output of the wind duct using a screen, automatically orienting according to the direction the wind. Whatever the direction and strength of the wind, the fumes can rise naturally above the exit of the duct, away from this screen, before dispersing.
  • This screen also protects the outlet of the conduit against the weather, and for example against a rain oblique incidence.
  • said drive means comprise at least one wind vane body.
  • the device is oriented according to the direction of the wind, without further assistance.
  • the screen and the wind vane plate are then placed at substantially different heights, for example one higher than the other, so that the screen does not hide the wind vane plate during slight changes. wind direction.
  • said drive means comprise electrically-controlled actuation means as a function of a wind direction measurement provided by an anemometer sensor.
  • the device according to the invention may for example be actuated by a stepper motor.
  • said screen is rotatably mounted about an axis integral with the outwardly facing face of a cap attached to said conduit.
  • the axis of rotation of the device is thus protected from smoke by the cap, and does not clog.
  • said screen extends between said cap and said conduit.
  • the wind and rain can not rush between the hat and the duct.
  • said screen is mounted on a driving swivel ring surrounding the outer contour of the conduit.
  • the drive of the screen is not in contact with the fumes, and does not clog.
  • said screen is curved so as to conform to a curvature of said duct.
  • the obstacle formed by the screen thus directs the wind to the rear of the duct. On the other hand, it reduces the passage between the screen and the duct, in which the wind can infiltrate.
  • a portion of said screen is disposed vis-à-vis said conduit.
  • said screen has at least one curved portion and / or inclined, so as to allow water settling on its surface to flow out of said conduit.
  • the screen may have a straight slope profile or a parabolic profile. In other embodiments of the invention, it may be a sudden enlargement.
  • said rotational drive means comprise a sealed ball bearing.
  • said screen and / or said body are formed of stainless steel, carbon fibers, a composite material and / or a thermosetting resin.
  • the screen and / or the wind vane body can also be made of copper or lacquered steel, or any other known material that is particularly resistant to the weather.
  • the invention also relates to a flue gas vent cap, having an axis projecting on its outwardly facing face, configured to receive a protection device such as those described above.
  • the principle of the invention is based on the implementation of a wind screen movable in rotation, oriented according to the direction of the wind.
  • the drive of this screen is advantageously protected from smoke and / or provided by the body of a wind vane, in preferred embodiments of the invention.
  • FIG. 2 an embodiment of a protective device 20 according to the invention, mounted on the cap 21 of a flue gas exhaust duct 29 of a chimney of a dwelling.
  • the outlet section 221 of the duct 22 is located above the housing floor, and no surrounding building prevents the dispersion of the fumes 29 under the effect of the wind.
  • the cap 21 which prevents the drop of raindrops in the conduit, is fixed by three tabs 23 above the conduit 22.
  • an axis 24, represented by dashed lines on the figure 2 protrudes upward.
  • the device 20 is mounted on a sealed ball bearing 25 in rotation about the axis 24.
  • the ball bearing is thus advantageously protected from the fumes by the cap 21.
  • This device consists of a vane body 26 carrying a wind screen 27 at the end of a first arm 261, and a stylized vane plate 28 at the end of the opposite arm 262.
  • the rings of the bearing 25 are respectively glued on the body 26 and the axis 24.
  • the screen 27 is supported by a tab 210 screwed onto the body 26 and the back of the screen. It extends substantially vertically under the arm 261 between the cap 21 and the edge 221 of the duct 22.
  • the lower portion 271 of the screen 27 advantageously surrounds the edge of the duct, in order to limit the passage of the wind under the screen 27 .
  • the screen 27 is disposed perpendicularly to the wind vane body 28. In an arc, the screen 27 matches an angular portion of the outer contour of the conduit 22. More specifically, a reduced space 41 equal 4 millimeters was provided between the inner surface of the screen 27 and the outside of the duct 22, as it appears more clearly in the vertical sectional view along AA, shown figure 4 .
  • the width of the screen 27 is substantially equal to that of the duct 22, to prevent the smoke stagnates at the outlet of the duct without being dispersed by the wind. Note also that the screen 27 promotes the dispersion of fumes by creating a Venturi effect on each of its side edges.
  • the fumes can easily escape from the duct, the outlet of which is only partially blocked by the screen, in the event of blockage of the rotation of the device.
  • the screen 27 is inclined by 7 ° relative to the vertical to allow incident raindrops deposited on its surface, and raindrops flowing from the cap 21, to flow away from the leads 22.
  • the wind vane plate 28 is fixed on the arm 262 in the plane of the wind vane body 26.
  • This wind vane plate 28 is designed to be pushed by the wind, so as to drive the wind vane body in the wind axis. and therefore to place the screen 27 facing the wind.
  • its stylized shape gives, in this particular embodiment of the invention, an aesthetic appearance to the device 20.
  • FIG. 5 Another embodiment of the invention is shown with reference to the figure 5 .
  • a curved windscreen 51 curved in an arc is fixed on a pivoting ring 52 forming the body of a wind vane surrounding the outer contour 53 of the duct 54.
  • the ring 52 is rotated by a vane plate 55 arranged in a radial direction and located on the ring in a position diametrically opposite the screen.
  • the pipe 54 is equipped with an overflow 56 protecting the ring 52 from the fumes folded down along the outer surface of the pipe 54.
