The present invention relates to a vehicle air conditioner, and more particularly, to a vehicle air conditioner having a front seat air conditioning unit and a rear seat console unit.

In general, the vehicle air conditioner is to create a comfortable environment by adjusting the temperature and humidity in the vehicle interior, and includes a cooling device for cooling the interior of the vehicle according to the purpose, and a heating device for heating the interior of the vehicle interior.

The cooling device is a device for producing cold air by absorbing the latent heat of vaporization necessary for the evaporation of the refrigerant from the air flowing around the evaporator while the refrigerant flows into the evaporator, and supplies the produced cold air into the cabin. In addition, the heating apparatus generally induces high temperature cooling water that cools the engine to the heater core, and heats the air flowing around the heater core by the coolant induced in the heater core to produce warmth. It is a device for supplying the inside of the vehicle.

However, in the vehicle air conditioner according to the related art as described above, a defrost duct and a vent duct provided at the rear end of the air conditioning case so as to discharge the air-conditioned air to a desired area in the vehicle compartment, respectively. Since the duct and the floor duct are disposed in front of the front seat, the cooling and heating efficiency of the rear seat is lowered. In particular, in the case of a passenger car or a van in which the interior of the vehicle is relatively large, there is a problem that the air-conditioned air is not sufficiently delivered to the rear seat.

In order to solve the problems as described above, there have recently been attempts to supply air, which is air-conditioned in various ways, to the area of the rear seat. As an example of such an attempt, Fig. 1 shows a vehicular air conditioner disclosed in Japanese Patent Laid-Open No. 195-32860.

Referring to the drawings, the vehicle air conditioner 10 is provided with an air conditioning case 11 having an air flow path therein. One side of the air conditioning case 11 is provided with a blower 12 for blowing air introduced from the air inlet into the air flow path, the doors are not shown in the interior of the air conditioning case 11 is installed It is selectively opened and closed to control the flow of air. The evaporator 21 and the heater core 22 are sequentially arranged on the air flow path of the air conditioning case 11 from the blower 12, and above the heater core 22 in the air conditioning case 11. In the corresponding position, the front seat cent 23, the side vent duct 24, the front seat floor duct 25, and the defrost duct 26 are installed above the heater core 22, respectively. 20), the air-conditioned air is discharged to the front seat area. Downstream of the heater core 22, a rear seat evaporator 31 is disposed on an air flow path of the air conditioning case 11, and corresponds to a rear side of the rear seat evaporator 31 in the air conditioning case 11. The rear seat vent duct 32 is installed at the position, and the rear seat floor duct 33 is installed at the position between the heater core 22 and the rear seat evaporator 31 to form a rear seat console unit 30. Air is discharged to the rear seat area.

As described above, the rear seat evaporator 31 is additionally employed in the rear seat console unit 30 provided in the vehicle air conditioner 10, due to the adoption of the rear seat evaporator 31. There is a problem that capacity should be increased.

Meanwhile, in addition to the rear seat evaporator, a rear seat heater core may be further provided in the rear seat console unit. In this case, the cost is excessively increased. In addition, due to the rear seat evaporator and the rear seat heater core, the flow resistance of the air is increased to reduce the air volume to the rear seat console unit may cause a problem that the cooling and heating efficiency in the rear seat area is lowered.
