Abstract

L'objectif de l'invention est de simplifier l'élimination de l'eau de condensation d'un dispositif de ventilation intégré à une fenêtre de ventilation. La fenêtre de ventilation (1) comprend un dispositif de ventilation (50) équipé d'un échangeur de chaleur (62) installé à l'intérieur d'un cadre (2) sur le côté vertical de la fenêtre de ventilation (1), un conduit de sortie (77) qui est situé après le conduit (62B) de l'échangeur de chaleur (62) dans le dispositif de ventilation (50) et qui se trouve dans le dispositif de ventilation (50) dans une connexion de drain avec l'extérieur (U), lequel conduit de sortie (77) comprend un guide (75) comme un creux, des surfaces de guidage inclinées et/ou un entonnoir, conçus pour guider l'eau de condensation à partir de l'embouchure du conduit (62B) de l'échangeur de chaleur (62), un tube de sortie (55) installé sur le guide (75), et un agencement (80, 85) pour maintenir l'eau fondue, le conduit de sortie (77) s'étendant sur toute la distance entre l'échangeur de chaleur (62) et l'embouchure (55b) du tube de sortie (55) à l'intérieur du dispositif de ventilation (50) et en outre de sorte que l'eau de condensation se déplace tout le temps vers le bas par la gravitation et avec un débit d'air.
