3 is a schematic diagram illustrating an air conditioner for a vehicle according to a first embodiment of the present invention.

As shown in FIG. 3 , in the vehicle air conditioner 100 according to this embodiment, an air inlet 220 including an inside air inlet 210 and an outside air inlet 211 is formed, and a cooling heat exchanger 230 is provided therein. a first unit 200 connected to the first unit 200, a second unit 300 communicating with the first unit 200 and having a blower 310 therein, and an all-seat heat exchanger communicating with the second unit 300 The front seat discharge unit 400 is provided with a 410 and has a front seat air outlet 420 through which air passing through the front seat heating heat exchanger 410 is discharged, and the second unit 300 communicates with the rear seat heating heat inside. It includes a rear seat discharge unit 500 provided with an exchanger 510 and having a rear seat air outlet 520 through which air passing through the rear seat heating heat exchanger 510 is discharged.

In this embodiment, unlike the conventional configuration in which bet or outside air is discharged into the interior of the vehicle sequentially through the blower, the evaporator and the heater core, the blower 310 is a cooling heat exchanger 230 and a heating heat exchanger 410 , 510), and is characterized in that the inside air or outside air is discharged into the interior of the vehicle via the cooling heat exchanger 230, the blower 310, and the heating heat exchangers 410 and 510 in sequence.

In the present invention, it has been described that the discharge unit is provided with a heating heat exchanger, but the heating heat exchanger may be a heater core that radiates heat or a PTC heater to be described later. Similarly, the cooling heat exchanger may be an evaporator that absorbs heat by the refrigerant circulated in the vehicle.

Accordingly, in the related art, since the air that has passed through the evaporator once by the blower passes through the heater core next, there is a problem in that it is difficult to directly control the amount of air flowing into the heater core 410. However, in the present invention, the blower ( 310 is disposed between the cooling heat exchanger 230 and the heater core 410 to directly control the amount of air passing through the cooling heat exchanger 230 and the heater cores 410 and 510 .

In addition, in this embodiment, unlike the prior art, the cooling heat exchanger and the heating heat exchanger are arranged side by side in one unit and do not occupy space, but rather the first unit 200 in which the cooling heat exchanger 230 is disposed and the front seat heating heat exchanger 410 . Since the front seat discharge unit 400 in which is disposed and the rear seat discharge unit 500 in which the rear seat heating heat exchanger 510 is disposed are separated from each other, the volume of the air conditioner can be remarkably reduced, so that the space inside the vehicle can be utilized. there is.

In addition, by using one blower 310, it is possible to individually discharge cold/hot air to all seats, thereby saving energy. For example, depending on the seated position of the occupant, even if the occupant is seated on the right side of the back seat of the autonomous vehicle for example, independent wind can be discharged only to the right side of the rear seat with one blower 310, and the front and rear seats Air can be discharged simultaneously or selectively to the

A condensate outlet (not shown) may be provided at the bottom of the 200 .

The second unit 300 is provided with a blower 310 therein, and selectively or simultaneously blows the air flowing in from the first unit 200 to the front seat discharge unit 400 or the rear seat discharge unit 500 . In this case, the amount of air blown to the discharge units 400 and 500 may be directly controlled by a control unit (not shown).

The blower 310 of the second unit 300 is configured as a scroll case in which a blower fan that forcibly blows air toward the discharge units 400 and 500 is installed. That is, the blower 310 has a conventionally known configuration, but in the present invention, it is characterized in that it is disposed between the first unit 200 and the discharge units 400 and 500 .

The front and rear seat discharge units 400 and 500 communicate with the second unit 300 so that air controlled from the blower 310 flows in, and at the end of the second unit 300, the front seat discharge unit 400 or the rear seat discharge unit It includes a ventilation control door 320 for adjusting the opening degree of the passage for blowing to the (500).

The front seat discharge unit 400 is provided with a front seat discharge port 421 and a front seat right discharge port 422, which are discharge ports for discharging wind into the interior of the vehicle, and the front seat temperature for controlling the temperature discharged to the front seat discharge port 421 A control door 411 and a front seat right temperature control door 412 for controlling the temperature discharged to the front seat right outlet 422 are provided on one side of the front seat heating heat exchanger 410 .
