Definitions

  • the present invention relates to a flue for evacuating fumes from rooms, in particular for evacuating cooking fumes.
  • Such flue advantageously may be used for extracting cooking fumes from kitchens of any type, for example within the scope of restaurants services, but also in private homes.
  • the flues the object of the present invention are used together with the so-called “filtering hoods” which extract cooking fumes and after filtering them, re-emit them into the same indoor room.
  • a flue known from the background art comprises a first vertical and rectilinear stretch.
  • Such first stretch has an inlet section which can be connected to any filtering hood on the market.
  • the outlet openings lie on respective parallel vertical planes.
  • the outlet openings are each closed by a respective grid so that it is possible to prevent the introduction of objects from the outside.
  • the grid following the transit of the cooking fumes, the grid generates turbulence in the fumes themselves.
  • the turbulence is transmitted therefore to the grid which, vibrating against the flue, becomes a significant source of noise.
  • the technical task at the basis of the present invention is to propose a flue for evacuating fumes from rooms, in particular for evacuating cooking fumes, which overcomes the above-mentioned drawbacks of the known technique.
  • One embodiment of the invention relates to a flue for evacuating fumes from rooms, in particular for evacuating cooking fumes.
  • Such flue comprises a first stretch that develops along a vertical direction from an inlet section.
  • the flue has at least one outlet opening for discharging the fumes along a substantially horizontal direction.
  • Such outlet opening has a height along the vertical direction and a width along a direction orthogonal to the vertical direction.
  • the flue 1 has a pair of openings 4.
  • Such openings 4 are symmetrical in shape and arrangement with respect to a centreline plane of the flue 1.
  • outlet openings 4 are rectangular-shaped.
  • the outlet openings 4 each have a height along the vertical direction "A" and a width along a direction orthogonal to the vertical direction "A".
  • Each second stretch 5 connects the first stretch 2 to a respective opening 4.
  • the upper surface 6 has a constant development along a horizontal direction parallel to the centreline plane. Contrarily, the upper surface 6 is inclined towards the centreline plane. In greater detail, the upper surface 6 is curved in the direction of the centreline plane.
  • the upper surface 5 has a first connection 8 at the nose 7.
  • connection portion 10b with the outlet opening 4.
  • connection portion 10b is opposite to the upper surface 5 and has a third connection 11 at the second connection 9.
  • connection portion 10b has a development which substantially follows the upper surface 5.
  • the side surface 10 also has a portion 10c that is transverse to the upper surface 5. Such transverse portion 10c substantially is arranged vertically.
  • the behaviour of a fluid current within a conduit is characterized on the basis of non-dimensional parameters, that is to say compared to a reference parameter of the same type.
  • the linear lengths are adimensionalized with respect to a distance "L1" between the outlet opening 4 and the centreline plane of the flue 1.
  • the surfaces are adimensionalized with respect to the area "S" of the outlet opening 4.
  • the adimensionalized distance between the inlet section 2a and the nose 7 is comprised between 0.7 and 0.75.
  • An adimensionalized radius of the mentioned first connection 8 is comprised between 0.03 and 0.06.
  • the adimensionalized length of the entrance zone 2b is less than 0.3.
  • the second stretch 5 has a plurality of transverse sections each defined by a respective vertical plane.
