As a result, outside air is introduced into the vehicle interior, and inside air is discharged from the duct 23 to the outside via the trunk room 26, so ventilation is performed, and the inside air temperature tr decreases as shown in Figure 3a, causing the outside air temperature to decrease. rapidly approaching ta. When tr becomes equal to ta and Vr=Va, the second control means of the control circuit 18 stops the rotation of the blower 22 based on this, sets the opening degree θ of the inside/outside air switching door 5 to 0, and changes the outside air introduction rate. is set to 0, the compressor is driven, and the evaporator 7 is operated. As a result, the inside air temperature tr further decreases and tr=
When td+2 (td: set temperature), the outside air introduction rate is gradually increased and maintained at 30%.

４の側部より吸入できる。 Therefore, according to this embodiment, the high-temperature interior air can be expelled rapidly, reducing the load on the compressor and saving power.Furthermore, since the blower 22 is provided, the pressure inside the vehicle can be reduced. It is possible to suppress the rise and increase ventilation efficiency, and since it is installed on the rear side of the passenger compartment, outside air can be introduced from the front to the rear of the passenger compartment, reducing the temperature of the entire passenger compartment.
It can improve the feeling of the passengers. Further, according to this embodiment, since the door 29 pulled by the return spring 28 is provided in the duct 27, when the blower 22 is stopped, the door 29 is restored by the spring 28 and closed, so that tr<ta. This can prevent outside air from flowing back through the duct 27 in the event of an accident. In addition, as shown in FIG. 2, the upper end of the grill 24 protrudes beyond the parcel tray 21, so even if cargo is placed on top of the grill 24, air is

In this case, the duct 23 is branched into the duct 27 that extends toward the trunk room 26 and has the door 29, and the duct 30 that recirculates air to the inside of the vehicle.
The end of the duct 30 opens from the parcel tray 21, and a grill 24 is provided in the opening 31 of the duct 30. A switching door 32 is located at a branch position between the ducts 30 and 27, and this switching door 32 is controlled by an actuator 33 to switch the air taken in from the intake port 25 to the ducts 27 and 30. duct 30
There is an air purifier 3 consisting of a filter, activated carbon, etc.
4 and a negative ion generator 35 are installed in parallel. Note that the control circuit 18 is sent an output from a sensor 36 that detects an operation of pulling out an ashtray in the vehicle. Also,

の寿命を長く保つことができる。 In the above configuration, when the cooler switch (not shown) is turned on when tr > ta, the first control means of the control circuit 18 sets the opening degree θ of the inside/outside air switching door 5 to the maximum and the rotation speed of the blower 6 as described above. is maximum, and 100% outside air is introduced. Further, the opening degree α of the switching door 32 is maximized as shown in FIG. 3c, and the blower 22 is driven to rapidly ventilate the air, resulting in a rapid decrease in tr. If ta > tr > td + 2, as described above, the second control means of the control circuit 18 will reduce the amount of outside air introduced to 0, but the blower 22 will continue to rotate and the opening degree α of the switching door 32 will be set to the minimum. Therefore, the air from the intake port 25 is sent to the air purifier 34.
and is returned to the passenger compartment via the negative ion generator 35.
This purifies the air and improves the feeling of the occupants. Furthermore, when Td+2>tr, and when the ashtray is pulled out during smoking, a small amount of outside air is introduced, and the air from the intake port 25 passes through the air purifier 34 and the negative ion generator 35 into the passenger compartment in the same way as above. Reflux. Therefore, air contaminated by smoking can be rapidly purified. Conventionally, the amount of outside air introduced during smoking is maximized, but this increases the inside air temperature TR, which increases the burden on the compressor.
In the present invention, since the amount of outside air introduced is zero or small, no load is placed on the compressor, and power saving can be achieved. In addition, an air purifier 34, a negative ion generator 35
is activated when the opening degree α of the switching door is at its minimum, which prevents unnecessary operations and extends the lifespan of these devices.

のフイーリングを向上できる。 As explained above, according to the present invention, the first blower takes in outside air from the front of the vehicle, while the second blower releases inside air from the rear of the vehicle. The air rise is suppressed by the second blower to increase ventilation efficiency, and hot air can be quickly blown away from the front to the rear of the vehicle. In addition, in the present application, when the inside air temperature becomes almost equal to the outside air temperature due to ventilation, or after a certain period of time has passed after ventilation has been performed, ventilation is stopped and the compressor for cooling is driven. Since the evaporator cools the inside air whose temperature has been lowered, it is possible to reduce the heat load on the compressor and save power. In other words, the inside air becomes extremely hot under the scorching sun, and it is completely useless to drive the compressor in such a case.Moreover, when the hot air is removed, the inside air is vented outside, so it is necessary to drive the compressor at this time to remove the inside air. Cooling is inefficient, and the present invention can eliminate this inconvenience. Further, the second invention is further configured such that after the ventilation is stopped, the inside air sucked by the second blower is returned to the passenger compartment through the air purification device, so that the air in the passenger compartment is purified and the feeling of the occupants is improved. You can improve.
