Further, the first duct 51 has a uniform cross-sectional area along the air flow path on a surface perpendicular to the air flow path. For example, the cross-sectional area M1 of the first flow path section 512 shown in FIG. 4 is the sum of the cross-sectional area M2 of the second flow path section 513 and the cross-sectional area M3 of the third flow path section 514 shown in FIG. equal. As shown in FIG. 3, a space is formed between the first duct 51 and the first support member 35 to accommodate a functional device having a predetermined function, such as a lighting device. In order to form this space, the second flow path section 513 and the third flow path section 514 are formed at a higher position than the first flow path section 512 and the fourth flow path section 515. , this is just one example. For example, all the flow path sections may have the same height. Moreover, when a functional device is not installed, it is not necessary to branch into the second flow path section 513 and the third flow path section 514.

The air supply unit 52 is connected to a first duct 51 and two second ducts 53 in a space between the ceiling 40 of the vehicle 1 and the exterior roof panel 11. The air supply unit 52 sucks air from the first duct 51 and sends it out to the two second ducts 53. The air blowing section 52 has a blowing fan 521 inside.

The air outlet 531 has a slit shape extending in the width direction of the vehicle 1, as shown in FIG. Specifically, the air outlet 531 has a slit shape extending in a direction substantially parallel to the width direction of the vehicle 1. Here, the direction substantially parallel to the width direction of the vehicle 1 also includes a direction inclined at a predetermined angle with respect to the width direction of the vehicle 1. As shown in FIGS. 5 and 6, the air outlet 531 is formed by attaching the folded portion 421 of the second opening 42 of the ceiling 40 to the inside thereof. Moreover, each of the front side air outlet 531a and the rear side air outlet 531b extends below the vehicle 1 at an angle with respect to the vertical direction. Furthermore, the inclination angle α1 between the direction in which the opening of the front side air outlet 531a corresponding to the front side seat of the vehicle 1 extends and the vertical direction is the angle α1 of the opening of the rear side air outlet 531b corresponding to the rear side seat of the vehicle 1. is smaller than the inclination angle α2 between the extending direction and the vertical direction (α1<α2).

Here, the volatile aroma substance is volatile aroma oil or the like. The air blowing unit 61 includes a blowing fan and a cartridge containing a volatile aromatic substance. Note that the air sent out by the air sending unit 61 may contain a deodorizing substance (for example, silver ions), an antioxidant, and the like in addition to a volatile aromatic substance.

The duct 62 includes an air outlet 621 that blows air containing volatile substances blown from the air blower 61 into the passenger compartment of the vehicle 1 through third openings 43 near the front pillar 12 on both sides of the vehicle body 10. has.

Next, the air blown out from the air conditioning system 50 will be explained. FIG. 10 is a diagram schematically showing the flow of air blown out by the air conditioning system 50 when an occupant is seated with the front seat facing forward of the vehicle 1. FIG. 11 is a diagram schematically showing the flow of air blown out by the air conditioning system 50 when an occupant is seated with the front seat facing rearward of the vehicle 1. Below, the state shown in FIG. 10 will be described as a first state, and the state shown in FIG. 11 will be described as a second state.

In the first state shown in FIG. 10, the air conditioning system 50 blows out diagonally backward downward air A1 from the front side blow-off port 531a toward the occupant U1 seated on the front seat SH1. Furthermore, in the second state shown in FIG. 11, the air conditioning system 50 blows out the air A1 from the front side outlet 531a toward the occupant U1 seated on the front seat SH1.

In the air conditioning system 50, since the air A1 blown out from each of the front side outlet 531a and the rear side outlet 531b convects in the cabin of the vehicle 1, the temperature in the cabin after starting the air conditioning system 50 becomes uniform. The time required for this can be reduced compared to a conventional air conditioning system installed in the instrument panel.

According to the first embodiment described above, the second duct 53 blows air into the vehicle interior through the second opening 42 formed above each of the four seats provided in the vehicle 1. Since the air outlet 531 is provided, air can also be applied to a passenger seated toward the rear of the vehicle 1.

Further, according to the first embodiment, since the air cleaner 54 is provided in the middle of the flow path between the suction port 511 and the blowout port 531, purified air is provided to the occupant U1 of the vehicle 1. It can be blown out.

Further, according to the first embodiment, since the air outlet 531 has a slit shape extending parallel to the width direction of the vehicle 1, the area of the opening in the ceiling 40 can be reduced, so that the appearance of the ceiling 40 can be improved. can do.

Further, according to the first embodiment, since the air outlet 531 is inclined with respect to the vertical direction and extends below the vehicle 1, the air A1 directed diagonally downward can be applied to the occupant U1.

According to the first embodiment, the inclination angle α1 of the front side air outlet 531a corresponding to the front seat of the vehicle 1 in the air outlet 531 is greater than the inclination angle α2 of the rear side air outlet 531b corresponding to the rear seat of the vehicle 1. Since it is small, air A1 can be directed toward the occupant U1 seated on the front seat SH1 regardless of the state of the front seat SH1.

Further, according to the first embodiment, since the suction port 511 is formed toward the upper side of the vehicle 1 in the horizontal direction, the air A1 blown out from the air conditioning system of the front panel can be efficiently sucked in.

Further, according to the first embodiment, since the cross-sectional area of the surface of the first duct 51 perpendicular to the flow path of the air A1 is uniform along the flow path, the air flowing in the first duct 51 is uniform. The flow rate can be kept constant.

In this case, as shown in FIG. 15, the ECU 104 drives the damper drive unit 57 to move the damper 56 to the position of the second flow path 534, thereby moving the damper 56 to the position of the second flow path 534. Cut off. Thereby, the air sent out by the air sending unit 52 flows only through the first flow path 533. As a result, air can be applied only to the occupant seated in the front seat, making it possible to perform efficient air conditioning.

According to the third embodiment described above, when only the seat sensor 101 provided on the front seat out of the four seat sensors 101 detects that an occupant is seated, the ECU 104 drives the damper drive section 57 to move the damper 56 to the first position. By moving to the position of the second flow path 534 and blocking the second flow path 534, air can be applied only to the occupant seated in the front seat, resulting in efficient air conditioning. It can be performed.

Note that in the third embodiment described above, the ECU 104 adjusts the air blown out from each of the plurality of air outlets 531 by moving the position of the damper 56 based on the detection results of the four sheet sensors 101. It is not limited to this. For example, a vital sensor that detects the vital information of the occupant may be provided in the vehicle 1, and the position of the damper 56 within the distribution section 532 may be adjusted by taking into account the detection results of this vital sensor. Thereby, air can be blown out precisely according to the physical condition of the occupant.
