Definitions

  • the invention relates to a chimney cap with a pipe socket, an inner jacket arranged coaxially to the latter, at least approximately pyramid-frustum-shaped, which projects above the pipe socket, and an outer jacket arranged coaxially to the latter, projecting upwards from the inner jacket and distanced from it to form an annular chamber , whose upper outlet opening is covered by a cover part arranged at a distance above it.
  • the object of the present invention is to create a chimney cap by means of which raining or snowing into the chimney can be avoided in a simple and safe manner even in extreme wind conditions.
  • the flow guide part has a cylindrical shape, the cross section of the cylindrical part being at least approximately the same area as the cross section of the pipe socket and its lower inlet part being widened to the outside.
  • the lower extended entry part forces because of its larger Entry surface of the exhaust gases rising from the pipe socket into the subsequent cylindrical or polygonal flow guide part.
  • the lower extension ensures that rain falling from above does not get into the chimney interior and evaporate there, thereby generating cold, but is diverted to the outside.
  • the upper outlet opening of the inner jacket is at least approximately the same area as the cross section of the pipe socket.
  • the lower edge of the outer jacket is higher than the lower edge of the inner jacket and the height of the outer jacket is greater than the height of the inner jacket. It has proven to be expedient if the outer casing has at least approximately the shape of the casing of a truncated pyramid or a regular prism, preferably with eight side faces.
  • the inner casing also has at least approximately the shape of the casing of a truncated pyramid with eight side faces, and it is expedient if the angle of inclination of the side faces of the inner and outer casing are at least approximately the same size, the side edges of the inner and the outer shell preferably lie on the corresponding diameter planes.
  • the chimney cap shown therein is provided with a pipe socket 1 to be inserted into the chimney outlet opening, a truncated pyramid-shaped inner jacket 2 which projects above the pipe socket 1, and an inner jacket 2 arranged coaxially with the latter protruding upward and provided by this to form a bottom and top open annular chamber 3 outer jacket 4.
  • the upper outlet opening 5 of the outer jacket 4 is covered by a cover part 14, which is arranged at a distance above this opening 5 and is normally arranged in a hinged manner.
  • the outlet opening 6 of the inner casing 2 approximately the same area as the flow cross-section of the pipe socket 1.
  • the lower edge 7 of the outer casing 4 is higher than the lower edge 8 of the inner casing 2, and the height H A of the outer casing 4 is greater than the height H I of the inner casing 4.
  • the inner and outer sheaths 2 and 4 have 4 the shape of the shell of a truncated pyramid with eight flat side surfaces.
  • the inner and outer sheaths 2 and 4 are provided with inner beads 9, which run about 5 mm wide and run along the corner edges formed between its side faces 4 s , and which at the same time lead into the interior of the interior. respectively outer shell 2 or 4 form directed flow guide ribs 10, the height h of which increases towards the top.
  • angles of inclination ⁇ 1 and ⁇ 2 of the side surfaces of the inner and outer shells 2 and 4 are approximately the same size, the side edges of the inner and outer shells lying on corresponding diameter planes d.
  • the pipe socket 1 with a to rest on the Chimney crown certain cover and support plate 11 connected, which extends in a plane perpendicular to the longitudinal axis 12 of the top.
  • the lower edge 8 of the inner shell 2 extends down to just above the top of the cover and support plate 11.
  • the pipe socket 1 and the cover and support plate 11 are preferably made of a copper alloy and are connected to one another with good thermal conductivity. Furthermore, the pipe socket 1 is provided with thermal insulation 13 on its outside over its length extending above the cover and support plate 11.
  • the cover and support plate 11 is indirectly heated by the flue gas flowing through the pipe socket 1, so that any condensate dripping down from the inner jacket 2 onto the cover support plate 11 is evaporated there.
  • a cylindrical one that projects upwards, is arranged coaxially to the longitudinal axis 12 and extends along the latter
  • Flow guiding part 15 is provided, the lower inlet opening 16 of which is flanged or widened outwards and seen in the axial direction of the attachment, projects above the upper outlet opening 6 of the inner casing 2, so that liquid on the outside of the flow guiding part 15 drips onto the outside of the inner casing 2 and this prevents it from getting into the interior of the fireplace.
  • the size of the upper outlet opening 5 of the outer casing 4 is dimensioned such that the flow cross-section this outlet opening 5 is approximately 64% larger than the flow cross-section of the flow guide part 15 located in the same plane.
  • the flow guide tube 15 could also have the shape of a truncated cone shell which widens downward or some other suitable shape.
  • the radius of the inner circle of the base surface 17 or 18 of the inner and outer shell 2 or 4 should preferably be 1.45 to 1.55 times as large as the radius of the inner circle of the top surface 6 or 5 of the inner or outer shell.
  • the diameter of the inner circle of the base surface 17 of the inner jacket 2 is, for example, 27 cm and the diameter of the inner circle of the top surface 6 of the inner jacket 2 is, for example, 19.5 cm, that is to say the same as the diameter of the pipe socket 1, which is also 19.5 cm is.
  • the height H I of the inner jacket 2 is 17 cm.
  • the diameter of the cylindrical part of the flow guiding part 15 is also 19.5 cm, which means that this diameter is also identical to that of the pipe socket 1.
  • Figure 3 is a second embodiment with a Outer jacket 4 'shown, the horizontal cross section of which has the shape of a regular prism.
  • inner and / or outer jacket 2 or 4 or 4 ' can also be provided with openings.
