Air conditioner for vehicle

Abstract

Disclosed herein is an air conditioner for a vehicle, which can prevent reduction of an air volume by reducing a back-and-forth width of the vehicle and sufficiently securing the degree of opening ofa warm air bypass door, and control an efficient linkage between the warm air bypass door and a defrost door. The air conditioner includes: an air-conditioning case having an air passageway formed therein; a heat exchanger for cooling and a heat exchanger for heating which are disposed in the air passageway of the air-conditioning case to exchange heat with air passing the air passageway; a warm air bypass passageway for directly discharging the air passing the heat exchanger for heating to a front seat floor vent; and a warm air bypass door for adjusting the degree of opening of the warm airbypass passageway, wherein the warm air bypass door includes a rotary shaft and a plate, and the plate has a bent portion to have at least two sides.

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 in which an upper flow path and a lower flow path are formed to individually control air conditioning of front seats and rear seats of the vehicle. Background technique [0002] In general, vehicle air conditioners are installed to cool and heat the interior of the car in summer or winter, or to remove frost that appears on the windshield in rainy days or in winter to ensure the driver's front and rear vision. Car interiors. An air conditioner usually has both a heating system and a cooling system, and selectively introduces external air or internal air, heats or cools the air, and sends air to the vehicle interior to cool, heat, or ventilate the vehicle interior. . [0003] Korean patent application No. 1484718 (2015.01.14) disclosed a vehicle air conditioner that adjusts the rear seat air volume by controlling the positions ...

AI Technical Summary

Problems solved by technology

[0011] In the case of a 3-zone air conditioner that performs temperature control on the independent 3-zone (3Zone) of the front driver's seat, front passenger's seat, and rear seat (rear seat), leakage (leak) is likely to occur through the hot air bypass door, In the case of reducing the width in the front-rear direction of the vehicle, it is disadvantageous to secure the amount of door opening, and thus there is a problem that the amount of air discharged to the front floor vents decreases.

[0012] At the same time, in the case of a 2-zone air conditioner that performs temperature control on separate 2-zone (2Zone) front seats (front seats) and rear seats (rear seats), the position of the floor vent outlets of the front seats is too low to be easily installed on the feet. Ducts are formed on the (Foot) side, and there is a problem that it is difficult to reduce the width in the front and rear directions of the vehicle, similar to the three-zone air conditioner.
