Abstract

The invention related to the condensate drain on an adjustable-angle roof ventilator of the cover/coupling type. The duct passing through the roof from below terminates in the lower section of the space enclosed by the coupling. A connector surface extends from the lower piece of the inside of the coupling innards to the outer surface of said duct. At the lowest lying contact patch of said connector surface with the coupling surface, the coupling surface is pierced by an outlet opening.

Description

  • The invention relates to a ventilation device which is fastened to the roof surface, projects upward above the latter and is typically used as an air connection for the wastewater ducting in a building.
  • DE 298 02 784 U1 describes a ventilation device projecting above the roof surface, according to which a tube made of plastic leads from below through an opening through the roofing tile. On the top side of the roofing tile, it is enclosed by the outlet tube projecting above the roof surface and made of a ceramic material. At the end face of the plastic tube leading through the roof, the outlet pipe has on the eave side, that is to say on the underside in the line of slope of the roof, a hole for draining the condensate.
  • A disadvantage with this type of construction is that the inclination of the outlet tube cannot be adapted to the roof inclination and that a considerable proportion of the condensate does not flow off from the outlet opening provided for this purpose but rather flows off via the end face of plastic pipe, leading through the roof, into the interior of the roof vent conduit. This is in particular a very large proportion if, as a result of a very low temperature in interaction with snow and ice alternating with pronounced heating through the vent tube, the hole for draining the condensate is temporarily obstructed on the outer side.
  • AT 412 793 B describes a roof ventilator which is also made of plastic in the part projecting above the roof surface. It consists of a tube passing through the roof plane, of a roofing plate from which a dome having a perforated top surface projects, and of a hood which is arranged above said dome and bears with its bottom margin against the outer surface of the dome and opens with its top margin into the outlet tube leading further upward. The hood is pivotable on the dome about an axis lying horizontally normal to the line of slope of the roof, whereby the outlet tube can be set perpendicularly irrespective of the inclination of the roof surface. The tube which passes through the roof surface is connected with its top end to the margin of the opening on the top side of the dome. The hood encloses this region while maintaining a gap, through which condensate which flows downward from the outlet tube can flow off to the outer side of the dome and thus to the top side of the roofing plate. A disadvantage with this type of construction is that the tube which passes through the roof also extends a considerable distance beyond the roof surface and that the condensate which precipitates on the inner lateral surface of this tube as a result of low temperature in this longitudinal region is not discharged outward but rather flows off into the interior of the roof vent conduit.
  • DE 200 21 051 U1 likewise describes a plastic roof ventilator which comprises a dome and a hood and is adjustable in inclination. In this case, the tube which passes through the roof surface and from which condensate can only flow off inward can even project a considerable distance beyond the top side of the dome.
  • The object of the invention is to provide a roof ventilator adjustable in inclination, in accordance with the dome/hood type of construction, in which, compared with known devices of this type, substantially less condensate which precipitates on the inevitably often cool inner surfaces of the roof ventilator flows off into the interior of the conduit leading to this roof ventilator from the building interior.
  • This object is achieved according to the features mentioned in the characterizing part of claim 1 in the following way:
  • The tube passing through the roof surface from below ends in the volume enclosed by the dome, approximately in the plane of the roof decking. A connecting surface extends from the bottom part of the inner side of the dome inward to the lateral surface of this tube. The dome surface is perforated by an outlet opening at that marginal region of this connecting surface which is on the eave side.
  • The invention will become clearer with reference to the drawings:
  • FIG. 1 shows a diagrammatic sketch of the invention in a lateral sectional view.
  • FIG. 2 shows, with respect to the embodiment in FIG. 1, the tube passing through the roof surface and the connecting surface, adjoining said tube in one piece, in a perspective view.
    •
  • According to FIG. 1, the dome 1.2 is formed in one piece with the roofing plate 1.1 lying in the roof plane. It arches outward from the plane of the roofing plate. It is provided with a top opening 1.3, over which the hood part (not shown here) is slipped. The leadthrough tube 2.1 passes through the plane of the roof decking from the building interior and ends just above said roof decking in the base region of the volume enclosed by the dome 1.2. In the example shown, the connecting surface 2.3 is produced in one piece with the leadthrough tube 2.1. It extends from the outer lateral surface of the leadthrough tube 2.1 to the bottom marginal region of the dome 1.2 and is welded there via a projected welding surface 2.4 to a welding surface 1.4 projecting from the roofing plate 1.1. Other types of connection, such as adhesive bonding or screwed connection using a sealing intermediate layer, are of course also conceivable. Given appropriate preparation, welding is a very cost-effective industrially applicable method and it leads to a very robust, reliably tight connection.
  • The leadthrough tube 2.1 projects only with a very short linear region 2.2 through the plane of the roof decking, whereby only a very much smaller part of the inner lateral surface is exposed to the precipitation of condensate compared with the previously known types of construction.
  • Condensate which precipitates on the inner side of the dome 1.2 and flows downward thereon as a further consequence is caught on the top side of the connecting surface 2.3 and flows further to the outlet opening 1.5, on the eave side, at the foot of the dome 1.2. It passes through this opening to the outer side of the roofing plate 1.1 in accordance with the intended use. Condensate which precipitates on the part or parts of the roof leadthrough which lead out via the dome and flows there into the interior of the dome likewise flows off through this outlet opening 1.5.
  • Owing to the fact that the top end face of the leadthrough tube 2.1 projects above that region of the connecting surface 2.3 which lies around the leadthrough tube, no condensate can flow from the ridge-side region of the connecting surface into the leadthrough tube.
  • Owing to the fact that the eave-side marginal region of the top end face of the leadthrough tube 2.1 lies at a distance from and above the outlet opening 1.5, and owing to the fact that the connecting line between leadthrough tube 2.1 and connecting surface 2.3 lies at a distance from the top end face of the leadthrough tube, buffer storage space is obtained for condensate. This may be advantageous, for example, when more condensate temporarily accumulates than can flow off. This is possible, for example, when dome 1.2 and roofing plate 1.1 are cooled markedly below the freezing point and suddenly very moist, warm air rises from the building interior. The condensate can then temporarily freeze at the opening 1.5 and constrict or close the latter. If there were then no buffer storage space for condensate, said condensate would flow off through the leadthrough tube into the conduits in the building.
