め，後席における空調効率が劣化する。However, in the above-mentioned "blow-out device for cold air or outside air in an automobile", the air flow from the rear seat outlet 1502 to the rear seat passes above the front seat occupant. Because of the configuration, the airflow reaching the rear seats is mainly the airflow flowing to the rear parcels and the airflow flowing between the front seats and flowing into the front seats, and no airflow that convections the rear seat living space evenly occurs. Therefore, the air conditioning efficiency in the rear seats deteriorates.

The purpose is to improve the air-conditioning efficiency of the rear seats by installing the air conditioners and controlling the air volume distribution in the front and rear seats appropriately.

It is distributed according to the opening degree. Then, a predetermined amount of conditioned air blows from the front seat outlet 111 toward the front seat 102.
Further, a predetermined amount of conditioned air is simultaneously blown out from the rear seat outlet 112, but the air flow A (see FIG. 1) in this case depends on the shape of the duct and the arrangement of the outlets, as shown by the arrow in FIG. It flows straight from the center position in the left-right direction to the rear without hitting the front passenger F, and reaches the chest height by the rear passenger 103R. As a result, the conditioned air is evenly distributed to the rear seats 103, and airflow interference with the front seats 102 does not occur.

The target outlet air temperature Tθf is calculated using tf, the amount of solar radiation S, and the outside air temperature Ta (S404). This ensures a sufficient cooling capacity. Next, the air mix door opening X is calculated based on the target blown air temperature Tθf (S40).
By 5), the conditioned air equivalent to the above cooling capacity can be obtained. Further, fan voltages (air volumes) Vff and Vfr required respectively for the front seat 102 and the rear seat 103 are calculated from the difference between the detected room temperature and the set room temperature (S406), and the total voltage becomes the fan applied voltage VF. Then, the air volume distribution door opening R of the front and rear seats is calculated from the fan voltage ratio Vfr / Vff of the rear seat to the front seat (S407), and then the above step S

The door opening R is set to 100%. Therefore, the map of the air volume distribution door opening R is set as a decreasing function with respect to the fan voltage ratio Vfr / Vff in the range of the door opening of 50% to 100%, and the fan voltage of the front seat 102, that is, the temperature. The larger the difference is, the larger the door opening R becomes, and the air volume distribution of the front seat 102 is increased.

れる。Therefore, when there is a large difference between the detected room temperature of the front seat 102 and the set room temperature, a large amount of sufficiently cooled conditioned air is blown out from the front seat outlet 111 and is preferentially air-conditioned. The temperature difference between the front seats 102 is efficiently reduced. Further, since the air is blown out from the rear seat outlet 112 with an air flow distribution of less than half, the rear seat 103 is maintained in a good air-conditioning state with a small temperature difference. In this way, the front and rear seats 102 and 103 are temperature-controlled without causing insufficient cooling capacity, and the temperature interference is reduced by the arrangement of the front and rear seat air outlets 111 and 112. Therefore, the front and rear seats are independently and appropriately temperature-controlled. It

θf is calculated (S408). Then, the air mix door opening X is calculated (S409) and the fan applied voltage VF is calculated.
Is calculated (S410), the air volume distribution door opening R of the front and rear seats is calculated from the fan voltage ratio Vff / Vfr of the front seat to the rear seat (S411), and the process returns to step S401.

Becomes smaller and the air volume distribution in the rear seat 103 increases. Therefore, when there is a large difference between the detected room temperature of the rear seat 103 and the set room temperature, a large amount of sufficiently cooled conditioned air is blown out from the rear seat outlet 112 to be preferentially air-conditioned, and The temperature difference of 103 is likewise effectively reduced.

When the connecting rod 1317 is moved to the lower limit, the other three louvers 1312 and 1313 rotate counterclockwise while the upper louver 1311 is kept horizontal as shown in (d), and the air flow is the same as above. It is turned upward without reducing the road area. At this time, the upper and lower louvers 131
Pins 1318 of 1, 1313 are all leaf springs 132
It is positioned by engaging with the upper part of 2.

ヤダクトが不要になり，低コスト化が図れる。As described above, according to the present invention, in the vehicle air conditioner, the rear seat air outlet is located at a substantially central position in the left-right direction of the instrument panel, and is in a range where the front seat occupant is not exposed to the air flow. It is installed so that it has a width and opens, and with the duct of the rear seat outlet facing straight toward the rear of the vehicle, the conditioned air blown from the duct curves so as to draw a parabola and reach the upper half position of the rear seat occupant. Because it will be formed
The airflow can be evenly distributed to the rear seats, and the interference of airflow in the front and rear seats is reduced, improving air conditioning efficiency. In addition, since the passengers in the rear seats do not hit the airflow directly, there is no single chill and a mild airflow feeling is obtained. The rear seat air outlet only needs to be in the center of the instrument panel, increasing the degree of freedom in designing the instrument panel. In addition, the rear duct is not needed, and the cost can be reduced.

ることができる。In the air conditioning control, the one having a large difference between the room temperature of the front and rear seats and the set room temperature is selected, the target blown air temperature is calculated using the selected signal, and the air mix door opening degree, the fan applied voltage, and the air flow rate are selected. Since the configuration is such that the distribution door opening is calculated, the front and rear seats can be efficiently air-conditioned at a desired temperature without causing insufficient cooling capacity. Also, temperature interference is reduced, and independent front and rear temperature control performance can be improved.

ることができる。At the time of selecting the signals for the front and rear seats, the transient or steady state is judged based on the difference between the room temperature of the front and rear seats and the set room temperature. If either of the front and rear seats is steady, the difference on the steady side is determined. Since the smaller one is selected, it is possible to prevent the feeling from deteriorating due to the low air temperature on the near steady side.

である。Further, in the wind direction control mechanism, the both end louvers are connected to the connecting rod by means having a function of positioning and diverting, and when both end louvers are regulated by the inner surface of the case, both end louvers are kept horizontal. As a result, the flow passage area is reduced and the ventilation resistance is prevented from increasing due to the Venturi effect, and the diversion performance is improved.
Since the louver is positioned according to the moving position of the connecting rod, the diverted state of the air flow can be reliably maintained. Since the positioning means is constituted by the engagement of the pin-shaped leaf spring provided in the long hole and the pin, the operation is smooth and the structure is simple.
