Definitions

  • the invention relates to an outer wall connection for a combustion air and exhaust gas duct of a device working with a burner system.
  • An outer wall connection of this type is known from DE-A-30 25 441.
  • the exhaust gas chamber ends with its exhaust gas outlet opening above the combustion air chamber in a plane which is substantially parallel to the room wall and is further away from the room wall than the plane of the combustion air inlet opening of the combustion air chamber.
  • Such a configuration with superposed openings of the exhaust gas chamber pointing substantially forward and combustion air chamber, the opening of the exhaust gas chamber being above that of the combustion air chamber, does not prove to be particularly favorable in every respect under the various wind and flow conditions to which external wall connections of mobile rooms - in particular caravans and mobile homes - are exposed.
  • Flow conditions with air flows obliquely from above are common in practice. They then cause the exhaust gas, which rises due to its higher temperature, to be pushed back or down into the exhaust gas duct and combustion air duct, which can lead to malfunctions.
  • the object of the invention is to provide an outer wall connection in which the problems described are eliminated.
  • the invention proposes an outer wall connection according to claim 1.
  • the exhaust gas can also emerge unhindered in the frequent wind currents directed obliquely from above against the outer wall connection, whereby it is distributed behind the combustion air inlet opening in ascending order around it, the combustion air inlet opening being provided by the cover acting as an aperture the exhaust gases are shielded.
  • cover plate according to claim 2 By designing the cover plate according to claim 2 with an edge angled into the space between the cover plate and the outer wall, a further improved shielding of the combustion air inlet opening from the exhaust gas is achieved.
  • An outer wall connection to be attached to a flange 7 in an opening in a wall of a mobile space, in which there is a burner system, designated as 1, has an exhaust gas chamber 2 and a combustion air chamber 3.
  • the exhaust gas chamber 2 is a tube-like duct, which has on its input side a connection piece 4 for connecting an exhaust gas hose leading to the burner system or the like and opens out into the open on the side remote from the connection piece via a downward-directed exhaust gas outlet opening 6.
  • the exhaust chamber 2 extends from its connector 4 to its outlet opening 6 obliquely downwards.
  • the combustion air chamber 3 is arranged above the exhaust chamber 2 and lies around the top of the exhaust chamber 2.
  • the envelope of the exhaust gas chamber 2 and the combustion air chamber 3 has an essentially cylindrical shape.
  • the combustion air chamber 3 has a connection section 5 on the room side, with which it can be connected to a combustion air hose or the like leading to the burner system, which surrounds the exhaust gas hose or the like.
  • the combustion air chamber 3 has a combustion air inlet opening 11 on the end face remote from the connection section.
  • This combustion air inlet opening 11 presents itself as a breakthrough of a cover plate 9, which otherwise covers the exhaust gas chamber 2 and the combustion air chamber 3 on the end face, or also closes, and is essentially parallel and at a distance from the mounting flange 7 and thus essentially also parallel to the wall in which the outer wall connection is to be installed runs.
  • the cover plate 9 extends in the radial direction over the above-mentioned envelope of the exhaust gas chamber 2 and the combustion air chamber 3, so that around the exhaust gas chamber 2 and the combustion air chamber 3 there is an annular space 8 delimited by the room wall or the flange 7, the envelope and the radially outer region of the cover plate 9, into which the exhaust gas chamber 2 with its exhaust gas outlet opening 6 flows down.
  • the combustion air inlet opening 11 passing through the cover plate 9 is located in a plane which is essentially perpendicular to the plane of the exhaust gas outlet opening and is also shielded from it by the cover plate 9 acting like a diaphragm.
  • An edge-side bend 13 of the cover plate 9, which is directed into the space 8, further improves this shielding effect.
  • hot exhaust gas emerging from the exhaust gas outlet opening 6 is distributed ascendingly in the space 8 around the exhaust gas chamber 2 and combustion air chamber 3 and moves away and is distributed in the radial direction away from the outer wall connection 1, so that penetration into the axially outward and through the Cover plate 9 shielded combustion air supply opening 11 is avoided.
  • cover plate 9 is a separate component; it can equally well be cast in one piece with the other parts of the outer wall connection, for example, with the same shape.
  • the design of the cover plate 9 as a separate component offers advantages in manufacture and maintenance.
  • the relatively large combustion air supply opening 11 is divided by a ring 15 and a web 16 in order to improve aesthetics and to reduce the possibility of foreign bodies entering the combustion air chamber.
  • the latter also serve to improve the rigidity of the arrangement.
