Definitions

  • the invention relates to a chimney cap according to the preamble of claim 1.
  • a known chimney cap which is said to have a train-supporting effect, consists of a tubular body made of concrete, which is attached to the chimney cover and which extends the chimney draft upwards somewhat beyond the chimney with the pipe interior. From above, the tubular body is covered with a cover plate, which is held over a circumferential spacing slot to the side walls. This slot is the outflow opening for the flue gas.
  • Inflow openings for ambient air are provided on the side walls, which have inclined surfaces towards the inside.
  • the slot as the outflow opening for the flue gas is only insufficient for a number of circumstances in terms of its position and size for the flue gas to flow out.
  • the flue gas builds up on the inside of the lid, which is further reinforced by the arching of the lid. Because of the obliquely and spirally arranged surfaces of the inflow openings, the ambient air sucked in should have a swirl, so that the flue gas mixed with the ambient air is to be set in rotation. But this is with a cross wind, i.e. a strong lateral air flow, practically no longer the case, so that a train-supporting effect is missing.
  • the known chimney cap also consists of concrete, which is heavily attacked by the flue gases, so that the life of this chimney cap is only relatively short.
  • the object of the invention is to create a chimney cap with improved function, in particular with a side flow.
  • the chimney extension pipe extension is provided, which can be fastened to the chimney cover with a bottom flange.
  • wind deflector profiles Distributed on the outer circumferential surface of the pipe attachment are several wind deflector profiles, preferably eight wind deflector profiles. These wind deflection profiles run in the vertical direction or in the axial direction of the pipe attachment over its axial length. The entire axial length is preferably provided with wind deflector profiles; in the case of particularly long pipe attachments, it may also be sufficient to turn the wind deflector profiles on in the upper region bring where they are at least necessary according to the invention.
  • Claim 2 also proposes a cover known per se, which is attached with the aid of supports above the pipe attachment. In order not to impede the vertically upward air flow in cross winds through the cover, it must not protrude laterally beyond the edge of the pipe attachment. In order not to hinder a chimney cleaning, the lid is expediently made hinged.
  • the chimney top with the wind deflector profiles and the cover makes the chimney largely independent of weather conditions.
  • the lid protects the chimney from precipitation and falling winds. The entry of cold air is prevented and the flue gases are prevented from cooling prematurely. In addition, even in cross winds, the chimney draft is stabilized by the design of the chimney cap according to the invention, which means that the combustion proceeds evenly and the fuels are optimally used.
  • a pipe socket-shaped ring which surrounds the pipe attachment and which is shorter in axial length than the pipe attachment.
  • the ring is connected on its inner surface to the outer edges of the wind deflector profiles, so that closed, vertical and nozzle-shaped channels are formed in the area of the ring.
  • the ring is in one attached to the upper area of the pipe attachment, so that the wind deflection profiles are open in the lower area of the pipe attachment and catch a side wind, which is then directed upwards through the closed channels and emerges in the area of the outer peripheral surface or the upper edge of the pipe attachment in an approximately vertical direction.
  • the ring protrudes slightly above the upper edge region of the pipe attachment, whereby the above effect is further improved by the fact that laterally acting air flows do not flow directly over the upper ends of the channel outlets, but are kept away from the somewhat higher edge region of the ring and then are better deflected upwards by the air flow leading vertically upwards.
  • the protrusion of the ring edge area must obviously be only slight in comparison to the distance of the cover above the edge of the pipe attachment, so that there is still enough space under the cover for an unobstructed outflow of the flue gas.
  • the effect of the ring is further improved with the features of claim 5 in that vertically standing wind deflector profiles are also distributed on the outer peripheral surface of the ring. This also traps a cross wind in the wind deflector profiles of the ring and is already largely deflected vertically upwards on its outer circumferential surface, as a result of which the overall flow leading vertically upwards is equalized and strengthened.
  • the wind deflector profiles on the ring are preferably smaller in radial extension than the wind deflector profiles on the pipe attachment. Due to the larger circumferential surface on the ring and the smaller overhang, it is advantageous to attach a larger number of wind deflector profiles. As cheap has a number of 16 wind deflector profiles on the ring and eight wind deflector profiles on the pipe attachment.
  • the wind deflector profiles are approximately U-shaped or V-shaped in cross-section.
  • the legs of such profiles are bent with respect to one another depending on the size of the chimney cap and the number of wind deflector profiles and the length of the legs.
  • the two legs can be approximately parallel or usually diverge at a larger angle.
  • the legs can also be bent into an approximately semicircular profile.
  • a good function of the chimney attachment according to the invention also depends on the dimensioning of the individual components.
  • a functionally favorable embodiment is achieved in the dimensioning proposed with claim 8.
  • the radial extension of the wind deflector profiles on the pipe attachment and correspondingly the ring distance from the pipe attachment should be about a quarter as large, the axial length of the ring should be about half as large and the protrusion of the cover the top of the pipe attachment is about three-eighths and the protrusion of the ring over the edge of the tubular attachment is about one-eighth as large.
  • a chimney attachment 1 which consists essentially of a cylindrical tube attachment 2 with a base plate 3 designed as a base flange, with which it is fastened by means of screw connections 4 on a cover plate 5 of a chimney 6.
  • Eight wind deflector profiles 7 are attached to the outer circumferential surface of the pipe attachment and evenly distributed on the outer circumferential surface.
  • the wind deflector profiles 7 shown here are longitudinal profiles with a V-shaped cross section, which lead in the vertical direction on the pipe attachment 2 over its entire length from bottom to top. With the tip of the V-formation, the wind deflector profiles 7 are connected to the outer circumferential surface of the tubular attachment 2 and project approximately radially therefrom with the V-legs.
  • a hinged cover 8 is attached over the pipe attachment 2 brings (opened position shown in dashed lines), which covers the surface of the pipe top from above and in particular does not protrude laterally.
  • the cover 8 is held at a distance above the tubular attachment 2 by means of supports 9. This distance corresponds to approximately three quarters of the diameter of the pipe attachment 2.
  • a cylindrical ring 10 which is also made of stainless steel just like the wind deflector profiles.
  • This cylindrical ring 10 is connected to the outer edges of the wind guide profiles 7, as a result of which closed, nozzle-shaped channels 11 are formed in the region of the ring 10.
  • the ring 10 is shorter in its axial length than the tubular attachment 2, so that the wind deflector profiles are exposed in a lower region of the tubular attachment and are covered in an upper region by the ring 10 and the aforementioned channels 11 are formed.
  • the ring 10 projects with a projection 12 over the upper edge of the tubular attachment 2, on which the wind deflector profiles 7 also end.
  • this projection 12 is less than the distance of the cover 8 from the upper edge of the pipe attachment 2, so that a relatively large outflow area 13 is retained for the flue gas.
  • Wind deflector profiles 14 are also attached to the outer circumferential surface of the cylindrical ring.
  • the shape of the wind deflector profiles 14 corresponds to that of the wind deflector profiles 7, but they are only half as large and distributed in twice the number on the ring 14.
  • the wind deflector profiles 14 also extend over the entire axial length of the ring 10.
  • FIG. 3 different versions of wind deflector profiles are shown in section.
  • the V-shaped embodiment in FIG. 3a corresponds to the embodiment in FIGS. 1 and 2.
  • 3b shows an approximately semicircular profile in cross section.
  • Fig. 3c corresponds approximately to that in Fig. 3a, only that a flat, widened base has been created here, which may simplify attachment.
  • FIG. 3d corresponds approximately to that in FIG. 3c, but here the protruding legs run approximately parallel.
  • the fireplace attachment 1 shown has the following function:
  • the arrows 15 indicate a cross wind, which would sweep directly over the chimney 6 without the chimney cap 1 and could severely hinder the escape of flue gases.
  • the side wind arriving at the height of the ring 10 is likewise deflected upward by the wind deflector profiles 14, as a result of which the air flow according to the arrows 16 is additionally promoted, in particular also by the projection 12 of the ring 10 over the upper edge of the tubular attachment 2.
  • the outflow area 13 under the cover 8 thus remains largely unaffected by the side wind flow, so that here the flue gas (arrows 17) can flow out unhindered against the side wind direction.
  • the invention provides a chimney cap with good function, which is also inexpensive to manufacture.
