<p>A ventilation hood (110) for placing on a house roof. The hood comprises a plate-shaped portion (111) which is arranged to rest upon the roof and which is provided with one or more opening(s) (112b) for the reception of air duct(s). The hood comprises, furthermore, a super-structure (114) which covers the opening(s) and at least a part of the plate-shaped portion (111). The super-structure (114) is by means of a partition wall (122) divided into two chambers, namely an approximately closed inner chamber (129) and a through-aired outer chamber (124). An outlet pipe union (131) from an air duct goes through the partition wall and opens out on the outer side of the partition wall in the outer chamber (124). By means of the ventilation hood the intention is to solve the problem of condensate which has a tendency to be formed on the inner side of the hood. The inner chamber (129) can with advantage form an inlet chamber for a fan (130) which is arranged in the inner chamber, so that one or more air ducts can easily be connected to said inner chamber and be operated by said fan.</p> |
