An extractor hood comprises: a housing for fixing to a building structure, for instance a wall, at a chosen position by means of fixing means, which housing (also) bounds a hollow space; an outlet connecting to this space for drawing off air, vapour and the like entering the space via an inlet by means of a fan placed at a distance via a suction conduit for coupling to said outlet; and a plate (also) bounding this space on the underside and having a generally downward convex form, which plate together with the side walls of the housing defines with its front side and both side parts three optionally mutually connecting vents forming the said inlet. |
