Air conditioner for vehicle

摘要

The present invention relates to an air conditioner for a vehicle that includes: a mode door having a thin. plate member, solidly operating inside an air-conditioning case to control the degree of opening of a defrost vent, a face vent and floor vents, and a gear shaft, engaged with the thin plate member for its operating; and constant discharging means disposed at a rail portion. of the thin plate member and at a guide part of an air-conditioning case overlapped with the rail portion, so that air of a fixed quantity is discharged to side vents of the face vent, thereby providing a simple structure and reducing manufacturing costs because the gear holes of the rail portion and the cut portions of the guide portion serve as the constant discharging means, without a need for additional structure to constantly discharge air toward the side vent.

主权项

1. An air conditioner for a vehicle comprising:
an air-conditioning case having an air inflow port formed on one side thereof and a defrost vent, a face vent and floor vents respectively formed on the other side thereof for discharging the air, which is introduced through the air inflow port; a mode door having a gear shaft, which is rotatably mounted inside the air-conditioning case and has gear portions, and a thin plate member, which is slidably mounted adjacent to the vents inside the air-conditioning case and has rail portions engaging with the gear portions of the gear shaft, for controlling the degree of opening of the vents; a guide part formed on an inner face of the air-conditioning case to cover the rail portions and overlapped with the rail portions of the thin plate member; and constant discharging means formed on the rail portions of the mode door and the guide part of the air-conditioning case so as to continuously discharge the inside air of the air-conditioning case toward one vent out of the vents; wherein the constant discharging means comprises aplurality of gear holes formed on the rail portions of the mode door so as to engage with the gear portions of the gear shaft; and cut portions formed on the guide part of the air-conditioning case by cutting a predetermined section of the guide part in a sliding direction of the thin plate member, so that air passing through the gear holes and the cut portions is continuously discharged to the one vent.
