The temperature regulating door 20 regulates the opening degree of the cold air passage P1 and the warm air passage P2 to control the mixing amount of the cold air and the warm air.

The mode door 14 has a structure similar to that of the temperature control door 20. Briefly, the mode door 14 includes a sliding door 14a slidably coupled to both inner sides of the air conditioner case 10, And a gear shaft 14b that is rotatably installed on both inner sides of the air conditioning case 10 to operate the sliding door 14a and meshes with the sliding door 14a.

FIG. 1 shows an example in which a flat mode door 15 is installed together with a sliding mode door 14.

According to the vehicle air conditioner 1 configured as described above, when the maximum cooling mode is activated, the temperature control door 20 opens the cold air passage P1 and closes the warm air passage P2. In addition, when the maximum heating mode is activated, the temperature control door 20 closes the cold air passage P1 and opens the warm air passage P2.

Therefore, when the maximum cooling mode is activated, the air blown by the blower (not shown) undergoes heat exchange with the refrigerant flowing in the interior of the evaporator 2 through the surface of the evaporator 2, Flows to the mixing chamber MC via the air outlet P1 and is discharged through the vent opened by the mode door according to the air discharge mode (vent mode, floor mode, defrost mode, bi-level mode, mix mode) And is discharged to the inside of the vehicle, thereby cooling the interior of the vehicle.

When the maximum heating mode is activated, the blowing air is heat-exchanged with the cooling water flowing in the heater core 3 through the heater core 3 through the hot air passage P2, MC, and is discharged to the vehicle interior through a vent opened by the mode door in accordance with the air discharge mode, thereby heating the interior of the vehicle.

1, the temperature control door 20 is rotated to a neutral position to cool the cool air passage P1 to the neutral position, as shown in FIG. 1, And the hot air passage P2 are both opened. Therefore, the cold air passing through the evaporator 2 and the hot air passing through the heater core 3 flow into the mixing chamber MC and are mixed and discharged into the vehicle interior through a vent opened by the mode door in accordance with the air discharge mode .

However, when the sliding type temperature control door 20 and the mode door 14 are operated, the area of contact with the air conditioning case 10 during operation of the sliding type mode door 14 is increased, As a result, the operating force of the mode door 14 increases during operation.

Also, the sliding door 14a has a small thickness, so that the strength of the door is lowered and the door is damaged.
