Abstract

L'invention porte sur une volute de ventilateur, comprenant un moteur (1), une volute (2) et une roue éolienne (3). La volute (2) comprend un boîtier supérieur (21) et un boîtier inférieur (22). Le boîtier supérieur (21) et le boîtier inférieur (22) sont superposés pour former une cavité de réception (23). La roue éolienne (3) est disposée dans la cavité de réception (23). La volute (2) est pourvue d'une première entrée d'air (24) et d'une première sortie d'air (25). La partie supérieure de la volute (2) est pourvue d'un trou traversant (26). Un arbre rotatif (11) du moteur (1) passe à travers le trou traversant (26) et est relié à la roue éolienne (3). Un connecteur de commutation (4) est prévu au niveau de la première sortie d'air (25) de la volute (2). Une seconde sortie d'air (41) est disposée sur le connecteur de commutation (4). Un déflecteur d'air (42) est disposé dans le connecteur de commutation (4). Le déflecteur d'air (42) est incliné vers la seconde sortie d'air (41). Lorsque de l'air est évacué de la première sortie d'air (25), la direction d'écoulement d'air est modifiée au moyen du déflecteur d'air (42), de telle sorte que le flux d'air est évacué de la seconde sortie d'air (41), et par conséquent, la perte du connecteur de commutation (4) sous pression d'air est réduite, le bruit est faible, la perte de volume d'air du flux d'air est réduite, et l'efficacité de fonctionnement du ventilateur est assurée.
