Ventilator with Condensed Water Drain

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.

1 . A roof ventilator which consists of a tube passing through the roof plane, of a roofing plate from which a dome having a perforated top surface projects above the roof surface, and of a hood arranged above said dome and pivotable relative thereto, characterized in that the leadthrough tube passing through the roof surface from below ends in the volume enclosed by the dome below the dome surface, a connecting surface extends between the lateral surface of the leadthrough tube on the one hand and the underside of the roofing plate or the bottom surface region of the dome on the other hand, and in that the surface, lying above the connecting surface, of the dome or of the roofing plate is perforated by an outlet opening close to the deepest point of the contact line with the connecting surface. 
   
   
       2 . The roof ventilator as claimed in  claim 1 , characterized in that the top end of the leadthrough tube is located in the base region of the dome. 
   
   
       3 . The roof ventilator as claimed in  claim 1 , characterized in that the connecting surface bears against the dome in the foot region of the latter. 
   
   
       4 . The roof ventilator as claimed in  claim 1 , characterized in that the top end face of the leadthrough tube projects above that region of the connecting surface which lies around the leadthrough tube. 
   
   
       5 . The roof ventilator as claimed in  claim 4 , characterized in that the connecting line between leadthrough tube and connecting surface lies at a distance from the top end face of the leadthrough tube. 
   
   
       6 . The roof ventilator as claimed in  claim 1 , characterized in that the deepest point of the top end face of the leadthrough tube is located above the level of the outlet opening. 
   
   
       7 . The roof ventilator as claimed in  claim 6 , characterized in that the distance of the end face of the leadthrough tube from the outlet opening is greater than the distance from that region of the dome which lies opposite the outlet opening. 
   
   
       8 . The roof ventilator as claimed in  claim 1 , characterized in that the outlet opening is located at the eave-side foot region of the dome. 
   
   
       9 . The roof ventilator as claimed in  claim 1 , characterized in that the leadthrough tube and the connecting surface are a joint part. 
   
   
       10 . The roof ventilator as claimed in  claim 1 , characterized in that the connecting surface is welded to the roofing plate or to the dome.
