The microcomputer 9 then enters the operating state by receiving a stabilized voltage of 5V from the on-vehicle battery via the stabilized power supply circuit.

１０１の判定がＮＯになる。In such a state, when the A/C switch 1 is not turned on and no A/C signal is generated, the motor of the sensor rotating section 5 does not operate, so the infrared sensor 3 does not rotate. Further, in the microcomputer 9, when the step 101 in FIG. 3 is reached, the determination is No.
Therefore, no arithmetic processing is performed for blowout control. This step 101 in FIG. 3 is periodically reached after other control calculation processing (not shown) is executed.
Until the A/C signal is generated from the C switch 1, the determination in step 101 is NO.

The outside temperature data Tam via the D converter 8 is input, and the process proceeds to step 103 where the outside temperature data Tam is set to a predetermined value.
For example, it is determined whether the temperature is greater than a value corresponding to 15°C. At this time, if the outside temperature is below 15°C, such as in winter, the determination will be NO and the calculation processing for blowout control will not be performed.If the outside air temperature is greater than 15°C, such as in summer, the determination will be YES. become. And step 104

The rotational position θ, the minimum position A, and the maximum position B indicate the counterclockwise angle from a certain reference position, as shown in FIG. 2(b), where A is 45° and B is 135°. ° is shown, A≦

07 processing ends, but if any one matches,
Temperature data is input from the infrared sensor 3 via the A/D converter 8, and the temperature data is stored in association with the rotational position at that time. Then, when the rotational position θ does not reach the minimum position A or the maximum position B, the above calculation process is repeated and temperature data for each predetermined angle is stored.

になる。After that, when the rotational position θ reaches the minimum position A or the maximum position B, the determination in step 105 or 106 is YES.
Become S. Then, the process proceeds to step 108, where the temperature data for each predetermined angle that has been stored up to that point is read out, and the temperature data are sequentially compared to select the rotation position at the highest temperature, that is, the direction of the high temperature part. Then, the process proceeds to step 109, where a control command is issued to the blowing direction switching section 11 to switch the blowing direction toward the high temperature section. In this case, data on the rotational position of the blowout grille is first inputted from the position sensor 7 via the A/D converter 8, and the airflow is determined by the difference between the rotational position and the direction of the high temperature part selected in step 108. A command signal for forward or reverse rotation of the motor is generated in the direction switching unit 11, and then the position sensor 7 monitors the rotational position data of the blowout grille via the A/D converter 8, and the rotational position is monitored. When the direction matches the previously selected high temperature section direction, a command to stop the motor is issued to the blowing direction switching section 11. As a result, the rotational position of the blow-off grill coincides with the direction of the high-temperature portion, and the conditioned air is blown toward the high-temperature portion.
以後、上記と同様の処理を繰返し、赤外線センサ３の回
動位置θが最小位置Ａあるいは最大位置Ｂに達すると、

向に吹出方向を切換えるようにしている。Thereafter, the same process as above is repeated, and when the rotational position θ of the infrared sensor 3 reaches the minimum position A or the maximum position B,
The direction of the high temperature part at the time of rotation is selected, and the blowing direction is switched to the direction of the high temperature part.

節にて行なうようにしてもよい。In addition, in the above embodiment, the air conditioning toward the high temperature part is performed by switching the blowing direction, but in the case of an apparatus equipped with a plurality of blowing outlets, air conditioning may be performed by selecting the blowing outlet. Alternatively, this may be done by increasing the air volume toward the high temperature area or by adjusting the temperature.

のを示したが、連続的に回転させるようにして用いても
よい。この場合、１回転毎に高温部方向を選定してその
方向への空調を行なうようにすればよい。Further, although the infrared sensor 3 is shown to be rotated within a range of about 90 degrees, it may be used by rotating it continuously. In this case, the direction of the high temperature portion may be selected for each rotation and air conditioning may be performed in that direction.

ようにしてもよい。Furthermore, we have shown a model that does not perform airflow control when the outside temperature is low, such as in winter, but in that case, the airflow is controlled in the direction of the low temperature area using the opposite logic to when the outside temperature is high, making it an all-season type. It's okay. Alternatively, the blowing direction may be determined based on the deviation between the vehicle interior temperature and the set temperature, without using the outside air temperature.
さらに、赤り）線センサ３にて検出する各部の温度が安
定してきたら吹出方向を周期的に回わすようにしてもよ

ことができるという優れた効果がある。As described above, in the present invention, the direction of the high temperature area within the temperature detection target range in the vehicle interior is searched and air conditioning is performed in that direction, so air conditioning control is performed in accordance with the temperature distribution in the vehicle interior. Therefore, it has the excellent effect of providing a very good cooling sensation even to the passengers who have entered the vehicle interior halfway.
