INTAKE DEVICE FOR AIR CONDITIONER OF VEHICLE WITH INSIDE AIR FLOWING INTO ON OUTSIDE AIR MODE

摘要

An intake device for a vehicle air conditioner for introducing room air in an atmospheric air mode is provided to connect an auxiliary door for an auxiliary room air inlet with a main door for atmospheric and room air inlets by link elements to open the auxiliary room air inlet when the main door opens the atmospheric air inlet, thereby introducing room air in the atmospheric air mode. An intake device for a vehicle air conditioner for introducing room air in an atmospheric air mode includes an auxiliary room air inlet(160) formed at a side of a housing(130) and mounted with an auxiliary door(161) for opening or closing the same. An auxiliary door driving shaft(162) serves as a rotation center of the auxiliary door. Link elements connect a driving shaft(150) of a main door(140) to the driving shaft of the auxiliary door for mechanical association between the main door and the auxiliary door. The link elements make the auxiliary door rotate with the main door in association for opening the auxiliary room air inlet while an atmospheric air inlet(110) is opened and a main room air inlet(120) is closed. The link elements are main and auxiliary door levers(171,172) respectively coupled with the driving shafts of the main and auxiliary doors, a connection link(173) connected to the auxiliary door lever, and a plane cam(174) fixed to the housing and formed with grooves(177,178) for guide protrusions(176,183) of the main and auxiliary door levers.
