Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a vehicle air-conditioning apparatus having an integrated door for an individual air-

The present invention relates to a vehicle air conditioning apparatus having a rear integrated door for individual air conditioning, and more particularly, to a vehicle air conditioning apparatus having an improved structure for preventing discharge to the side of the console and ventilation during individual air conditioning only for the driver in the vent mode, floor mode, And more particularly, to a vehicle air conditioner having a rear integrated door.

Generally, the vehicle is provided with an air conditioner for the convenience of the driver and passengers, so that the front and rear visibility of the driver is secured by cooling and heating the interior of the vehicle during the summer or winter, I will.

Such an air conditioner is usually equipped with a heating device and a cooling device at the same time, and selectively introduces outside air or indoor air, and then the air is heated or cooled to blow air into a vehicle interior to cool, heat or ventilate the interior of the vehicle.

In recent years, so-called left and right independent air conditioners have been applied in which individual temperatures are supplied to the driver's seat and the passenger's seat at different temperatures according to the needs of passengers, thereby enabling individual cooling and heating.

As an example of a conventional vehicle air conditioner, Korean Patent Registration No. 10-1403440 (registered on May 28, 2014) discloses a vehicle air conditioner 1 schematically shown in a sectional view in FIG. 1, in which an air inlet 11 is formed at one side And the other side is provided with a defrost vent 12a, a face vent 12b, and floor vents 12c and 12d which are opened by mode doors 16a, 16b and 16c, respectively; An evaporator (2) and a heater core (3) provided on the air passage in the air conditioning case (10) at regular intervals in order; And an air blowing device connected to the air inlet 11 of the air conditioning case 10 to blow air or outside air.

A cooling air passage P1 for bypassing the heater core 3 and a warm air passage P2 for passing through the heater core 3 are disposed between the evaporator 2 and the heater core 3, A ventilation mode, a ventilation mode, a floor mode, a mix mode, a defrost mode, and a ventilation mode are provided in the mode doors 16a, 16b, and 16c, ). A floor flow path 13 is formed in the air conditioning case 10 and is partitioned into a rear side warm air passage P2 of the heater core 3 and a partition wall 17. The floor flow path 13 is formed in the air- The air in the case 10 is guided to the floor vents 12c and 12d. The floor vents 12c and 12d are composed of a floor vent 12c for a front seat and a floor vent 12d for a rear seat and are branched from the floor flow passage 13. [

A console duct 20 (not shown) is provided on the outer side of the air conditioning case 10 on the rear side of the floor flow path 13 to guide the discharge of air to the console box side Is installed. One end (inlet side) of the console duct 20 is connected to the face vent 12b so as to be connected to the console vent. The air directed through the face vent 12b is guided to the console box, The rear seat space is cooled and heated.

In such a conventional automotive air conditioner, a rear floor floor vent 12d is provided together with the front seat floor vent 12c branched from the floor channel 13 when the mode door 16c is opened, Cool air or warm air is always discharged through the floor vent 12d for the rear seat so that the individual air conditioning for the driver can not be performed fundamentally.

Another air conditioning apparatus for a vehicle is disclosed in Korean Patent Laid-Open No. 10-2010-0104781 (published on Sep. 29, 2010) and Korean Patent Laid-Open Publication No. 10-2014-0055246 (published on May 31, 2014) There is a problem in that the air is discharged to the side.

Since the structure of the conventional vehicle air conditioner in which air is discharged to the back side during individual air conditioning is particularly driven by a battery, the air conditioner of an environmentally friendly car such as an HEV or an EV car is driven by a battery. The increase in ventilation loss and the power consumption of the air conditioner result in shortening the EV mode time and reducing the fuel consumption.

Korean Registered Patent No. 10-1403440 (Registered on May 28, 2014) Korean Patent Publication No. 10-2010-0104781 (published on September 29, 2010) Korean Patent Laid-Open No. 10-2014-0055246 (published May 2014, 2014)
