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.

The heating apparatus generally induces high temperature coolant that has cooled the engine to the heater core, and generates warmth by heating air flowing around the heater core by the coolant induced in the heater core. It is a device that supplies the vehicle interior.

However, in the conventional vehicle air conditioner as described above, a defrost vent, a face vent, and the like installed at the exit end of the air conditioning case in order to discharge the air-conditioned air to a desired area in the vehicle cabin, respectively, in front of the front seat. Since it is arranged, 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 car is relatively large, there is a problem that the heat exchanged 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 the heat exchanged air to the area of the rear seat in various ways. As an example of such an attempt, 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.

Air is discharged to the rear seat area.

In the vehicular air conditioner described with reference to FIG. 1, a 4-zone control (4-zone) capable of independently controlling air conditioning conditions of the left and right regions of the rear seat as well as the left and right regions of the front seat of the vehicle interior, respectively. Like so-called control, so-called multi-zone control is possible.

However, in the air conditioner of the multi-zone control type as described above, there is a problem in that the cost is excessively increased because additional rear evaporators and rear heater cores are used.

On the other hand, there is a problem that the proper means for properly adjusting the amount of air flowing into the rear seat console unit 30 is not provided. The amount of air flowing into the rear seat console unit 30 can be adjusted by installing a door that operates in a rotating manner in the front seat air conditioning unit 20, but the opening and closing of the rotating door does not change linearly, thereby substantially adjusting the amount of air.
