The defrost vent 53, the face vent 54 and the floor vents 55 and 56 are selectively provided with vents (not shown) in accordance with the respective blowing modes such as the defrost mode, the face mode, and the floor mode in the cooling mode and the heating mode A defrost vent door 57, a face vent door 58, and a floor vent door 59 for opening and closing the doors 53, 54, 55 and 56, respectively.

In this case, a duct (not shown) is connected to each of the vents 53, 54, 55, and 56 to discharge air into the vehicle interior. One portion of the duct is seated on the upper end of the air conditioning case 50 in which the face vent 54 is formed, and a sealing member is interposed between the duct and the upper end of the air conditioning case 50. In this way, the air discharged through the face vent 54 is discharged through the interior of the duct to the vehicle interior.

In particular, the vehicle air conditioner 100 has a duct sensor 60, the duct sensor 60 is mounted on the air discharge port side of the air conditioning case (50). The duct sensor 60 senses the temperature of the air discharged through the duct. The duct sensor 60 senses the actual temperature of the air discharged to the outlet of the duct and performs temperature control by comparing it with the set Mokpo discharge temperature of the control system.

As a result, the duct sensor 60 may detect the actual temperature of the air discharged through the duct while being located in the air conditioning case 50. Accordingly, as the temperature of the air going to the outlet side of the duct can be measured without installing the duct sensor 60 in the duct, the duct sensor 60 can be prevented from being separated or damaged during the transfer of the duct. Can be.

In addition, the duct sensor 60 is disposed outside the rotation area of the vent door. That is, in the present embodiment, the duct sensor 60 is mounted on the opening side of the face vent 54, more specifically, outside the rotation region of the face vent door 58 for adjusting the opening degree of the face vent 54. Is placed on. In this case, the outside of the rotation region of the face vent door 58 means the upper region of the face vent door 58 which does not overlap with the rotation range of the face vent door 58. As a result, the face vent door 58 is rotated without interference with the duct sensor 60, and the air passing through the face vent door 58 is sensed by the duct sensor 60.

Through such a configuration, interference between the face vent door 58 and the duct sensor 60 can be avoided, a space for the duct sensor 60 can be easily assembled, and the measured temperature and the actual temperature of the duct discharge port Can minimize the difference.

In addition, the face vent 54 provided in the air conditioning case 50 is provided with side vents 550 for discharging air to both sides of the vehicle and a center vent 560 for discharging air to the vehicle center side, and the side vents 550. ) And the center vent 560 are partitioned off by the partition wall 555. In addition, the air conditioning case 50 is provided with an actuator 70 for driving the face vent door 58 on the outside of the side vent (550).

In this case, the duct sensor 60 is mounted on the side surface of the air conditioning case 50 in which the side vents 550 are formed, that is, the side surface of the air conditioning case 50 on which the actuator 70 is mounted. Therefore, it is possible to measure the temperature of the air discharged to both sides of the vehicle after passing through the interior of the duct through the side vent 550, the assembly of the duct sensor 60 is easy and add a space for installing the duct sensor 60 There is no need to secure.

That is, the duct sensor 60 is composed of a sensor main body 61 and a temperature sensor 62. The sensor main body 61 is disposed outside the air conditioning case 50 and is mounted on the same surface as the actuator 70 mounted outside the side vent 550. The temperature sensor 62 detects the temperature of the air passing therethrough and extends to one side of the sensor main body 61. In addition, the temperature sensing unit 62 penetrates the air conditioning case 50 and is disposed inside the air conditioning case 50. In this case, a through hole for inserting the temperature sensing unit 62 is formed at the side surface of the air conditioning case 50.

Through this configuration, a series of assembling processes for mounting the duct sensor 60 to the air conditioning case 50 are facilitated, and the flow of air discharged as the sensor main body 61 is disposed outside the air conditioning case 50. Resistance is minimized.

On the other hand, Figure 5 is a cross-sectional view of a vehicle air conditioner according to another embodiment of the present invention, Figure 6 is a partially enlarged perspective view of the vehicle air conditioner according to another embodiment of the present invention. The air conditioner for a vehicle according to another embodiment of the present invention described with reference to FIGS. 5 and 6 further optimizes the position of the duct sensor as compared with the above-described embodiment, and the same configuration will not be repeated, and the same reference numerals are used.

In this case, the duct sensor 60 is arranged on the line extending upward from the pivot shaft 581 of the face vent door 58. As such, when the vent door is configured as a center pivot type, the air divided into the cold and warm air by the vent door is met again at a downstream point, which is the upper part of the vent door, so that the duct sensor 60 is disposed above the pivot shaft. Thus, the mounting position of the duct sensor 60 is optimized in that it minimizes the difference between the measured temperature of the air and the actual discharge temperature.

In this case, the duct sensor 60 is mounted on the side surface of the air conditioning case 50 in which the side vents 550 are formed, that is, the side surface of the air conditioning case 50 on which the actuator 70 is mounted. Therefore, it is possible to measure the temperature of the air discharged to both sides of the vehicle after passing through the interior of the duct through the side vent 550, the assembly of the duct sensor 60 is easy and add a space for installing the duct sensor 60 There is no need to secure.

That is, the duct sensor 60 is composed of a sensor main body 61 and a temperature sensor 62. The sensor main body 61 is disposed outside the air conditioning case 50 and is mounted on the same surface as the actuator 70 mounted outside the side vent 550. The temperature sensor 62 detects the temperature of the air passing therethrough and extends to one side of the sensor main body 61. In addition, the temperature sensing unit 62 penetrates the air conditioning case 50 and is disposed inside the air conditioning case 50. In this case, a through hole for inserting the temperature sensing unit 62 is formed at the side surface of the air conditioning case 50.

Through this configuration, a series of assembling processes for mounting the duct sensor 60 to the air conditioning case 50 are facilitated, and the flow of air discharged as the sensor main body 61 is disposed outside the air conditioning case 50. Resistance is minimized.
