Definitions

  • the present invention relates to a chimney for the discharge of smoke and residual combustion products from a flue and to a relative component.
  • the invention pertains to the field of chimneys for the suction and the flow of smoke from the combustion of solids, liquids and gases by fireplaces, thermal chimneys, stoves, heat stoves, boilers, and so on.
  • a known drawback occurring in known-art chimneys lies in the fact that air currents or turbulences having a substantially ascensional or descensional component may cause the refluxing of smoke and residual combustion products into the flue and/or the entering into the flue of rain, hail, snow and foreign bodies in general.
  • FR 1 520 726 discloses a chimney cap having a lens-shaped upper cover, a lower tapered defluxion member and a sleeve circumscribed to the first two elements.
  • DE926 873 discloses a flue associated with a cover member and with a tapered member fitted onto and crossed by the flue.
  • GB 448 285 discloses a ventilator for internal environments having a flat cover member facing a conical member.
  • FR 1 461 055 discloses an aeration device comprising an upper, dome-shaped cover associated with a counter-cover member in form of a closed semi-sphere and with a surrounding annular member.
  • the technical problem underlying the present invention is that of providing a chimney allowing to overcome the drawbacks mentioned above with reference to the known art.
  • the present invention provides some relevant advantages.
  • the main advantage lies in the fact that the presence of a defluxion member and of a cover, cooperating in diverting ascensional and descensional air currents, prevents said currents from concerning the flue and from dragging rain, hail, snow or foreign bodies in general into the latter, and/or from determining a reflux of smoke and residual combustion products into the flue.
  • the chimney of the invention allows an efficient and effective bidirectional flow of smoke, dusts and residual combustion products in general from the flue, i.e. an upward as well as a downward defluxion of the latter.
  • the chimney cap allows keeping the pressure in the flue substantially constant, thereby obtaining a smooth defluxion of smoke and residual combustion products therefrom.
  • a chimney cap for the defluxion of smoke F and/or of other residual combustion products from a flue 100 towards the outside is generally indicated by 1.
  • the chimney cap 1 comprises a cover member 2, hereinafter called 'cover' for simplicity's sake, located above the flue 100 in a position vertically spaced from the outlet 101 of the smoke and combustion residual products coming from the flue 100 itself.
  • the cover 2 has an external contour 20 having a substantially tapered shape, e.g. conical or pyramidal, and in particular with a section decreasing bottom-to-top.
  • the cover 2 is supported onto the flue 100 according to conventional modes.
  • the chimney cap 1 further comprises a defluxion member, or counter-cover, 3, located at the outlet 101 of smoke and residual combustion products.
  • the counter-cover 3 has a tubular structure.
  • it comprises a first portion 31, substantially sleeve-shaped and apt to externally engage a sheathing member 4, or plating, of the actual flue 100, it also having a tubular shape.
  • the counter-cover 3 is made fixed with the flue 100.
  • the counter cover 3 further comprises a second shaped portion 32, located above the first portion 31 and having an external contour 30 substantially shaped as a frustum-of-cone or as a frustum-of-pyramid, and in particular having a section decreasing top-to-bottom. This second portion 32 projects externally with respect to the flue 100 and to its sheathing member 4.
  • tubular structure of the counter-cover 3 allows smoke and residual combustion products to be outletted from the flue 100 and the sheathing member 4 by going through the shaped portion 32.
  • counter-cover 3 and the sheathing member 4 have been depicted as distinct bodies, in a variant embodiment they can also be made integral the one to the other, and optionally also to the flue 100. Moreover, the plating 4 can also be absent.
  • the overall arrangement of the cover 2 and of the counter-cover 3 is such that an interspace 5 is defined therebetween to discharge smoke and residual combustion products in general towards the outside.
  • the cover 2 and the counter-cover 3 have an arrangement that is substantially specular the one with respect to the other; likewise, the respective external contours 20 and 30 are substantially specular.
  • the chimney cap 1 of the present embodiment further comprises an external shielding member 6 for said interspace 5, apt to prevent the entering of horizontal air currents into the flue 100.
  • the shielding member 6 is located around the cover 2 and the counter cover 3, so that between it and such portions there is defined a flow interspace 7 having a substantially vertical development.
  • the shielding member 6 is opened at its top and at its bottom in order to allow the inlet and the outlet of air and smoke, or it has top and bottom openings suitable for the purpose. In order to allow an effective defluxion of the residual combustion products towards the outside environment, the shielding member 6 has a substantially tubular shape.
  • the shielding member 6 is connected to the flue 100 by conventional means.
  • the chimney cap 1 of the present embodiment provides, in a cross section, a substantially quadrangular geometry.
  • variant embodiments may provide any one alternative geometry.
  • Viable materials for manufacturing the different components of the chimney cap 1, and in particular the cover 2 and counter-cover 3, are copper, stainless steel, galvanised steel and cement composite.
  • both the cover 2 and the counter-cover 3 redirect the descensional and the ascensional air currents, respectively, so as to determine an effective dragging of smoke and residual combustion products towards the outside of the chimney cap 1, as indicated always in Figure 2 , thereby allowing the abovementioned bidirectional defluxion of the residual combustion products.
  • cover 2 and the counter-cover 3 effectively convey the ascensional and descensional currents into the interspace 7 defined between them and the shielding member 6, thereby fostering the dragging of smoke and the like towards the outside.
  • fumes are made flow along the natural direction of the atmospheric currents.
  • the shielding member 6 prevents the entering into the space 5, and therefore potentially into the flue 100, by horizontal air currents.
  • the chimney cap allows the defluxion of smoke and the like regardless of atmospheric conditions, land morphology and local context with reference in particular to what is nearby and how it is shaped.
  • the chimney cap is of easy and cost-effective manufacturing.
  • the chimney cap is also highly versatile, and it is apt to internal and external applications and on any type of flue.
  • the chimney cap of the described embodiment requires no maintenance, as it has no moving members and it is self-cleaning. Always by virtue of the fact that there are no moving members, the chimney cap is not noisy.
  • disassembling the cover 2 may facilitate the cleaning of the flue 100.
  • the improved defluxion of smoke and other residual combustion products associated with the present invention further provides a greater freedom of installation of the chimney cap with respect to the ridge of the roof.
  • the chimney cap may also be provided in form of a kit for its installation.
  • the chimney cap may also be provided in the context of a system for sucking smoke and the like additionally comprising a flue onto which the former is to be assembled.
  • both the cover and the defluxion member may have any external contour apt to divert the descensional or ascensional currents as described above.
  • the chimney cap is apt to be applied on flues arranged in a series, even on the same level, without negative interferences for to the discharging of smoke and the like.
  • the counter-cover and/or the plating of the flue to which it is integral may engage the flue internally rather than externally.
  • the defluxion member, or counter-cover, of the chimney cap may also be provided to end users separately from the other chimney cap members, and optionally associated with a chimney cap having a conventional cover.
