Air conditioner for vehicle

Abstract

The present invention relates to an air conditioner for a vehicle that includes: a mode door (130) having a thin plate member (150), which slidably operates inside an air-conditioning case (110) to control the degree of opening of a defrost vent (112), a face vent and floor vents, and a gear shaft, which engages with the thin plate member for operating the thin plate member (150); and constant discharging means (119) disposed at a rail portion of the thin plate member (150) and at a guide part of an air-conditioning case (110) overlapped with the rail portion (155), so that air of a fixed quantity is discharged to side vents of the face vent (113), thereby providing a simple structure and reducing manufacturing costs because the gear holes of the rail portion (155) and the cut portions of the guide portion, which are the constant discharging means, can be used as a constant discharge structure without needing additional structure to constantly discharge air toward the side vent.

Description

technical field [0001] The present invention relates to an air conditioner for a vehicle, and more particularly, to an air conditioner for a vehicle including a constant discharge device to discharge a constant amount of air. Background technique [0002] Generally, a vehicle air conditioner is a part of a vehicle, which is installed in the vehicle for the purpose of cooling the interior of the vehicle in summer, heating the interior of the vehicle in winter, or defrosting the windshield during the rainy season or winter, thereby Ensure the driver's front and rear vision. Such an air conditioner generally includes both a heating device and a cooling device, thereby selectively introducing inside air or outside air into the air conditioner, heating or cooling the introduced air, and blowing the heated or cooled air into the vehicle. steps to heat, cool or ventilate the interior of the vehicle. [0003] According to the installation structure of the blower unit, evaporator u...

Problems solved by technology

[0016] In addition, in an air conditioner using one or two mode doors to open and close the defroster vent 12a, the front vent 12b, and the floor vents 12c and 12d, in the case where the end plate 16c of the mode door is formed relatively small, This causes deterioration of the air conditioning performance by leaking a predetermined amount of air toward the defroster vent 12a or the floor vents 12c and 12d.
