I just need.

Next, the operation of the present apparatus will be described based on the flowchart of FIG. 6 showing the operation procedure of the ventilation control means 31. In the flowchart of FIG. 6, first, the ventilation control unit 31 determines whether the manual switch 26 is on or off (S · 1). If the manual switch 26 is on, based on the operation signal from the ignition switch detection unit 23, It is determined that the engine has stopped (S2). If the engine has stopped, the voltage V of the solar cell 18 is compared with the drive set voltage V1 by the voltage comparison means 32 of the ventilation control means 31 (S · 2).
3) If the voltage V of the solar cell 18 is equal to or higher than the drive voltage V1 (12 volts), then the ventilation control means 31 sets the in-vehicle air blower 2 to the air conditioning mode based on the detection signal from the air conditioning mode detection means 25. Detects the open / closed state of each outlet 5, 6, 7
These are compared with a state in which the outside air is introduced, the vent side outlet 6 is opened, and the other outlets 5 and 7 are closed (S · 4), and the air conditioning mode switching means 33 of the ventilation control means 31 sets the air conditioning mode. The outside air is introduced, the ventilating side outlet 6 is opened, and the other outlets 5, 7 are changed to the closed mode (S5). Next, the temperature comparison means 34 of the ventilation control means 31 determines that the in-vehicle temperature T based on the detection signal of the temperature sensor 20 is the drive set temperature T1 (35 °
C) It is compared whether it is equal to or more than (S.6). If the drive set temperature T1 has been reached, the illuminance comparison means 35 of the ventilation control means 31 sets the illuminance L based on the detection signal of the illuminance sensor 19. It is determined whether the illuminance is equal to or higher than the set illuminance L1 (50,000 lux) (S · 7). The ventilation control means 31 determines that the illuminance L is 500
If it is not less than 00 lux, the electric opening and closing device 15A is driven to open the side window 15 by H2 (50 mm) (S ·
8) If the illuminance L is less than 50,000 lux, the side window 15 is opened by H1 (20 mm), and then it is determined whether the blower fan 10 is driven (S · 10).
Since the blower fan 10 is stopped at the beginning,
The blower fan 10 is driven by the output of 18 (S · 1
1).

When the blower fan 10 is driven, outside air is blown out from the ventilating side outlet 6 into the vehicle interior 3 and discharged outside through the openings of the left and right side windows 15, 15 to ventilate the vehicle interior 3. Will be In this case, the illuminance L
A predetermined amount H for opening the side window 15 based on the size of
1 and H2 are adjusted, and when the illuminance L is large, the temperature inside the vehicle T generally rises quickly. Therefore, by widening the side window 15, the ventilation inside the vehicle can be performed quickly.
In the vehicle 1 having the front and rear side windows 15 as shown in FIG. 2, it is preferable to control the rear side windows 15 to be opened from the viewpoint of air flow. The side window 15 may be opened at least one place on the right side and one place on the left side.

Next, after the blower fan 10 is driven, the temperature comparison means 34 of the ventilation control means 31 compares the in-vehicle temperature T with the set stop temperature T2 (S12), and the in-vehicle temperature T becomes the set stop temperature T2. If the engine has stopped, it is determined whether the engine has stopped (S.13).
The voltage V of the solar cell 18 and the stop setting voltage V2 (10 volts)
(S14), and while the voltage V exceeds the stop set voltage V2, return to (S7) to adjust the opening amount of the side window 15 based on the illuminance L. Hereinafter, the same control is performed.

On the other hand, by comparing the voltage V of the solar cell 18 with the stop set voltage V2 (10 volts) (S · 14), the voltage V
Is less than the stop set voltage V2, the blower fan 10
Is stopped (S · 15), and the process returns to before the comparison (S · 12). By setting the stop setting voltage V2 of the blower fan 10 lower than the drive setting voltage V1, the drive setting voltage V
The intermittent operation of the motor 12 due to a voltage change near 1 is prevented. For example, even if the sun is shaded due to the movement of clouds or the like, the motor 12 does not stop every time if it is temporary, so that the durability of the motor 12 is not impaired. Further, even when the blower fan 10 is stopped (S · 15), if the vehicle interior temperature T is equal to or higher than the stop set temperature T2 (S · 12) and the engine is stopped (S · 13), the comparison (S · 14) is performed. ), The voltage V
Exceeds the stop set voltage V2, after the determination regarding the illuminance L (S.7) is made, the blower fan 10 is driven again (S.11).

After the blower fan 10 is driven, the temperature comparison means 34 of the ventilation control means 31 compares the in-vehicle temperature T with the set stop temperature T2 (S · 12), and the temperature in the car T is equal to or lower than the set stop temperature T2. , The ventilation control means 31
Is stopped (S.16), and then the electric window 15A is driven to close the side window 15 (S.17). After the blower fan 10 is driven, the ventilation control means 31 sets the vehicle temperature T
If the temperature exceeds the stop set temperature T2, it is determined that the engine is stopped (S13). If the engine is not stopped, the blower fan 10 is stopped (S16). Drive the device 15A to close the side window (S
・ 17). The case where the engine is driven is, for example, a case where the driver returns to the parked vehicle 1 and starts the engine.

The above-described flowchart shown in FIG. 6 is repeated while the manual switch 26 is on and the engine is stopped.

Next, with reference to FIGS. 7 and 8, the operation of the vehicle interior ventilation according to the present invention will be described. As shown in FIG. 7, the temperature is measured at a point C near the roof 17 in the vehicle interior 3, a point F near the floor, and a point S substantially at the center in the height direction. FIG. 8 is a graph showing the relationship between temperature and time when the air conditioner cooling operation is performed using the means 9. As shown in the graph, generally, when the vehicle 1 is parked under the scorching sun or the like, the temperature at the point C near the roof 17 becomes maximum. On the other hand, by opening the upper part of the side door 13 and discharging the inside air therefrom, the temperature rise near the point C can be suppressed efficiently. Further, since a rise in the temperature of the roof 17 can be suppressed, a decrease in the electromotive force of the solar cell 18 due to the rise in the temperature can also be suppressed.

In addition, the taken-in outside air is automatically discharged from the gap of the side window 15 opened by a predetermined amount to the outside of the vehicle, so that it is possible to suppress an increase in the vehicle interior temperature T during parking under hot weather. Therefore, even if the air conditioner is used after the engine is started, the load on the air conditioner can be reduced, the fuel efficiency can be prevented from deteriorating due to the high temperature inside the vehicle, and the compressor used for the air conditioner can be of small capacity.

As described above, according to the present embodiment, claim 2
In response to the above, an illuminance sensor 19 for measuring the illuminance L is provided, and the opening degree of the side window 15 is controlled by the level of the illuminance.

However, when the illuminance is high during the daytime in the middle of summer, the temperature inside the vehicle rises quickly. Thus, the temperature rise in the vehicle can be effectively suppressed. For example, (S · 6) in the flowchart of FIG.
Is omitted or the drive set temperature T1 is set low, the vehicle 1 increases in-vehicle temperature T corresponding to the illuminance L of the sunlight due to the greenhouse effect of the sunlight.
, The in-vehicle ventilation can be started at a time that is more appropriate in comparison with the case where the in-vehicle ventilation is performed based on the in-vehicle temperature T.

In response to the above, an intrusion detection sensor 42 for detecting intrusion of the side window 15 into the open / close position is provided, so even if the side window 15 is automatically opened under the control of the ventilation control means 31, If you put your hand in the place,
This is detected by the intrusion detection sensor 42, and the side window 15 is detected.
Can be closed or reported.

As an effect of the embodiment, the outside air is blown out from the ventilating-side outlet 5 among the plurality of outlets 5, 6, 7, so that the inside air in the vicinity of the roof 17 of the vehicle interior 1 can be effectively reduced. Therefore, a rise in the temperature of the roof 17 can be suppressed, and a decrease in the electromotive force of the solar cell 18 due to the rise in the temperature can be suppressed. Further, by providing the temperature sensor 20 on the headrest 22 on the front seat, the roof 17 having a high temperature rise rate can be provided.
The vehicle interior temperature T in the vicinity can be measured.

It should be noted that the present invention is not limited to the above embodiment, and various modifications can be made within the scope of the present invention. For example, in the embodiment, the opening / closing of the outlets 5, 6, 7 is operated by the outside air introduction switching means, but the opening / closing of the outlets 5, 6, 7 is not necessarily required. Further, the mounting position of the illuminance sensor can be appropriately selected.
