An embodiment disclosed herein relates to a blower unit for a vehicle, and an air conditioning device comprising same. The blower unit comprises: a scroll case having a suction port formed therein; a fan rotatably disposed inside the scroll case; a motor having a shaft coupled to the fan; and a bell mouth disposed at the suction port, wherein an inner end of the scroll case forming the suction port is disposed radially apart from the fan so as to form a gap, and the bell mouth prevents air flowing due to the rotation of the fan from flowing backward through the gap. Accordingly, the blower unit for a vehicle, and the air conditioning device comprising same can prevent the backflow of air to the outside of the scroll case through the arrangement of the bell mouth and the scroll case and the structural shape of the bell mouth.

    L'invention concerne, selon un mode de réalisation, une unité de soufflante pour un véhicule, et un dispositif de climatisation la comprenant. L'unité de soufflante comprend : un boîtier de volute ayant un orifice d'aspiration formé à l'intérieur de celui-ci ; un ventilateur disposé de manière rotative à l'intérieur du boîtier de volute ; un moteur ayant un arbre couplé au ventilateur ; et une embouchure évasée disposée au niveau de l'orifice d'aspiration, une extrémité intérieure du boîtier de volute formant l'orifice d'aspiration étant disposée dans le sens radial à distance du ventilateur de manière à former un espace, et l'embouchure évasée empêchant l'air s'écoulant du fait de la rotation du ventilateur de s'écouler de retour vers l'arrière au travers de l'espace. En conséquence, l'unité de soufflante pour un véhicule, et le dispositif de climatisation la comprenant peuvent empêcher le retour d'air vers l'extérieur du boîtier de volute au travers de l'agencement de l'embouchure évasée et du boîtier de volute et de la forme structurelle de l'embouchure évasée.

    실시예는 흡입구가 형성된 스크롤 케이스; 상기 스크롤 케이스의 내부에 회전 가능하게 배치되는 팬; 상기 팬에 결합되는 샤프트를 구비하는 모터; 및 상기 흡입구에 배치되는 벨마우스를 포함하고, 상기 흡입구를 형성하는 상기 스크롤 케이스의 내측 단부는 상기 팬과 반경방향으로 이격되게 배치되어 이격공간을 형성하며, 상기 벨마우스는 상기 팬의 회전에 의해 유동하는 공기가 상기 이격공간을 통해 역류하는 것을 방지하는 차량용 블로워 유닛 및 이를 포함하는 공조장치를 개시한다. 이에 따라, 상기 차량용 블로워 유닛 및 이를 포함하는 공조장치는 벨마우스와 스크롤 케이스의 배치 및 상기 벨마우스의 구조적 형상을 통해 스크롤 케이스의 외부로 공기가 역류하는 것을 방지할 수 있다.
