Disclosed is a blowing unit of an air conditioner for a vehicle, having a two-layer structure and capable of effectively suppressing a flow of air flowing backward around a scroll bell mouth. In a blowing unit of an air conditioner for a vehicle, having a scroll case in which a first flow path and a second flow path are partitioned so as to separate inside and outside air to be sucked, the scroll case has a partition wall for separating a suction part of the first flow path and a suction part of the second flow path, and the partition wall has an air backflow prevention part for preventing air flowing into one of the first flow path or the second flow path from flowing backward into the other.

    La présente invention concerne une unité de soufflage d'un climatiseur de véhicule présentant une structure à deux couches et permettant de supprimer efficacement la circulation d'air vers l'arrière autour d'un orifice évasé en spirale. L'unité de soufflage du climatiseur de véhicule comprend un boîtier en spirale dans lequel un premier trajet d'écoulement et un second trajet d'écoulement sont séparés de façon à séparer l'air intérieur et l'air extérieur à aspirer, le boîtier en spirale comporte une paroi de séparation pour séparer une partie d'aspiration du premier trajet d'écoulement et une partie d'aspiration du second trajet d'écoulement, et la paroi de séparation a une partie de prévention de reflux d'air pour empêcher l'air circulant dans le premier trajet d'écoulement et/ou le second trajet d'écoulement de circuler vers l'arrière dans l'autre trajet.

    2층류 구조의 송풍유닛에 있어서 스크롤 벨마우스 주변으로 역류하는 공기의 유동을 효과적으로 억제할 수 있는 차량용 공조장치의 송풍유닛이 개시된다. 차량용 공조장치의 송풍유닛은 내기와 외기를 나누어 흡입할 수 있도록 제1 유로와 제2 유로가 구획 형성된 스크롤 케이스를 구비하는 차량용 공조장치의 송풍유닛에 있어서, 상기 스크롤 케이스에 제1 유로의 흡입부와 제2 유로의 흡입부를 구분하는 격벽이 구비되고, 상기 격벽에 제1 유로 또는 제2 유로 중 하나로 유입되는 공기가 다른 하나로 역류하는 것을 억제하는 공기역류방지부가 구비된다.
