Description

Air blowing device

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is based on Japanese Patent Application No. 2017-141083 filed on Jul. 20, 2017, the contents of which are incorporated herein by reference.

The present disclosure relates to an air blowing device mounted on a vehicle.

BACKGROUND Conventionally, there is known an air blowing device that blows air from an air blowing port provided at an outer edge of a door opening when a passenger gets on and off, and reduces foreign matter entering the vehicle interior from the door opening.
In the device described in Patent Document 1, a plurality of air outlets provided from the A pillar on the front side of the front door opening to the roof side rail on the upper side direct air to the lower side of the front door opening. An air curtain is formed at the front seat door opening portion. This device prevents the ingress of dust such as pollen from the outside of the vehicle into the vehicle compartment by the air curtain when the front door opening is opened as the passenger gets on and off.
Patent Document 1 describes that an air supply source for supplying air to a plurality of air outlets is constituted by a blower provided in an air conditioner mounted on a vehicle.
Further, Patent Document 1 describes that the air supply source is configured by a compressor mounted on a vehicle and an air tank that stores air compressed by the compressor.

Patent No. 4033176

By the way, when a door opening part is opened at the time of a passenger's getting on and off, foreign substances, such as a mosquito, may invade into a vehicle interior from the door opening part. Mosquitoes are pests that mediate infectious diseases such as malaria and dengue fever. Therefore, if mosquitoes intrude into the vehicle compartment, there is a risk that safety, safety and comfort of the vehicle interior space may be impaired.
As in the apparatus described in Patent Document 1 described above, when the air supply source is configured by a fan provided in the air conditioner, the distance between the fan and the air outlet becomes long, and the duct connecting the fan and the air outlet is connected. Ventilation resistance increases. On the other hand, since the flight speed of a mosquito is about 2.5 m / s, in order to prevent the invasion of a mosquito, a wind speed and volume larger than that of preventing the invasion of dusts such as pollen are required. Therefore, in the device described in Patent Document 1, it is difficult to obtain the wind speed and the air volume necessary to prevent the entry of mosquitoes from the door opening.
In addition, when a plurality of people get on the vehicle and some of them get off, etc., the air conditioner blows the conditioned air into the vehicle compartment and the plurality of air outlets to the door opening. It is necessary to make it compatible with the operation of blowing air. However, as in the device described in Patent Document 1, when the air supply source is configured by the blower provided in the air conditioner, it is difficult to make the two operations compatible.
Furthermore, when the air supply source is configured by a compressor and an air tank as in the device described in Patent Document 1 mentioned above, there is a concern that the size of the device is increased and the manufacturing cost is increased.

An object of the present disclosure is to provide an air blowing device capable of reducing the entry of foreign matter into a vehicle compartment from a door opening.

According to one aspect of the present disclosure, an A-pillar provided on the front side of a front seat door opening corresponding to a front seat, a rear seat door opening corresponding to a second row of seats from the front and a front seat door opening An air blowing device mounted on a vehicle having a B-pillar provided between the vehicle and a C-pillar provided behind the rear seat door opening,
A blower for blowing air drawn in from the vehicle compartment;
A duct provided along the B-pillar and through which the air blown from the blower flows;
A plurality of blowout nozzles for blowing out the air flowing through the duct to the outside of the front seat door opening or the rear seat door opening at a predetermined angle to generate an air flow that prevents foreign matter from entering the vehicle compartment;
In the vehicle front-rear direction, the distance between the B-pillar and the blower is closer than the distance between the A-pillar and the blower and closer than the distance between the C-pillar and the blower.

According to this, since the distance between the blowout nozzle and the blower becomes short and the duct communicating between them becomes short, it is possible to reduce the ventilation resistance of the duct. Therefore, the air volume blown out from the blowout nozzle increases. Therefore, this air blowing device can obtain the wind speed and the air volume necessary to reduce the intrusion of foreign substances such as mosquitoes from the front seat door opening or the rear seat door opening into the vehicle compartment.
Moreover, since this air blowing apparatus does not have a compressor and an air tank like the above-mentioned patent document 1, while being able to miniaturize the physique of an apparatus, it can reduce manufacturing cost.
Furthermore, this air blowing apparatus can blow out air to both the front seat door opening and the rear seat door opening from the plurality of blowing nozzles by providing a duct provided with the blowing nozzle along the B-pillar.

Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In the following embodiments, parts identical or equivalent to each other are given the same reference numerals, and descriptions thereof will be omitted.

First Embodiment
A first embodiment will be described with reference to the drawings. As shown in FIGS. 1 to 4, the air blowing device 1 of the present embodiment is mounted on a vehicle, and blows air to the

door openings

3 and 4 when getting in and out of the occupant 2 to open the door opening 3, 4 to reduce the infiltration of foreign substances such as mosquitoes into the passenger compartment.

As shown in FIGS. 1 and 2, the air blowing device 1 is mounted on a vehicle having an A pillar 5, a B pillar 6, and a C pillar 7. The A-pillar 5 is a pillar of the vehicle body provided on the front side of the front seat door opening 3 corresponding to the front seat. The B-pillar 6 is a pillar of a vehicle body provided between the rear door opening 4 and the front door opening 3 corresponding to the second row of seats from the front and connecting the roof and the locker panel. The C pillar 7 is a pillar of a vehicle body provided behind the rear seat door opening 4 and connecting the roof and the locker panel. In this vehicle, a front air conditioner unit 8 is mounted inside the instrument panel.

As shown in FIGS. 1 to 5, the air blowing device 1 includes a blower 10, a duct 20, an air passage switching mechanism 30, a plurality of blowing nozzles 40, a control device 50, and the like. Although FIG. 4 is a perspective view of the air blowing device 1 of the present embodiment, the vehicle bodies such as the A-pillar 5, the B-pillar 6, and the C-pillar 7 are not shown.

The blower 10 is a centrifugal blower including a centrifugal fan such as a sirocco fan or a turbo fan, and an electric motor for driving the centrifugal fan. Blower 10 sucks in air from the passenger compartment as shown by arrow A1 in FIGS. 1 and 2. The blower 10 blows the sucked air to the plurality of blowout nozzles 40 via the duct 20. The centrifugal blower 10 can increase the static pressure more than the dynamic pressure of the air being blown, so in a circuit where the pressure loss is relatively large, the wind speed and volume of the air blown out from the plurality of blowout nozzles 40 It is suitable to increase.

The blower 10 is provided in a ceiling reinforcement provided so as to straddle the B pillars 6 on the left and right in the vehicle width direction. As shown in FIG. 2 and FIG. 4, the blower 10 is provided at a position on the ceiling of the vehicle away from the top of the head of the occupant 2 seated in the seat of the vehicle. Moreover, the blower 10 is provided in the center part in the vehicle width direction among the ceilings of a vehicle.

In FIG. 1, a position where the blower 10 can be installed is indicated by a two-dot chain line. Blower 10 is provided at a position where the distance between B pillar 6 and blower 10 is closer than the distance between A pillar 5 and blower 10 and closer than the distance between C pillar 7 and blower 10 in the vehicle longitudinal direction.
Specifically, when the blower 10 is provided at the position indicated by the two-dot chain line BL1 in FIG. 1, a part of the rear of the blower 10 and the B pillar 6 overlap when viewed from the vehicle width direction, The distance between the B-pillar 6 and the blower 10 is zero. The distance between the front end of the blower 10 and the A-pillar 5 is the distance indicated by the arrow D1. Therefore, when blower 10 is provided at the position indicated by the two-dot chain line BL1 in FIG. 1, blower 10 has a distance between B pillar 6 and blower 10 in the longitudinal direction of the vehicle of A pillar 5 and blower 10. It can be said that it is closer than the distance. In this state, it is apparent that the distance between the B-pillar 6 and the blower 10 is shorter than the distance between the C-pillar 7 and the blower 10.

On the other hand, when the blower 10 is provided at the position indicated by the two-dot chain line BL2 in FIG. 1, the distance between the front end of the blower 10 and the B pillar 6 is the distance indicated by the arrow D3 when viewed from the vehicle width direction. The distance between the front end of the blower 10 and the C-pillar 7 is the distance indicated by the arrow D2. Here, the distance indicated by the arrow D3 is smaller than the distance indicated by the arrow D2. Therefore, when blower 10 is provided at the position indicated by the two-dot chain line BL2 in FIG. 1, blower 10 has a distance between B pillar 6 and blower 10 in the longitudinal direction of the vehicle of C pillar 7 and blower 10. It can be said that it is closer than the distance. In this state, it is clear that the distance between the B-pillar 6 and the blower 10 is shorter than the distance between the A-pillar 5 and the blower 10.

The duct 20 is an air passage forming member for blowing air from the blower 10 to the plurality of blowout nozzles 40. Air blown from the blower 10 flows through the duct 20. As shown in FIG. 4, the duct 20 has a ceiling duct 21 provided on the ceiling of the vehicle, and a support duct 22 provided along the B-pillar 6. The ceiling duct 21 is provided so as to be hidden behind the roof lining of the vehicle and invisible to the occupant 2 in order to ensure the appearance of the vehicle interior. The support duct 22 is provided in a state integrated with the B-pillar in the vertical direction of the vehicle.

As shown in FIG. 3, the B-pillar 6, which is a pillar of a vehicle body, is configured by welding an outer frame 61 and an inner frame 62. An interior material 63 is provided on the vehicle interior side of the B-pillar 6. The portion of the duct 20 provided on the vehicle interior side of the B-pillar 6 is fixed to the surface of the interior material 63 on the vehicle interior side and extends in the vehicle vertical direction. An outer wall on the vehicle interior side of the duct 20 forms an interior design surface. Inside the duct 20 is a front seat door side air passage 71 through which air for blowing out to the outside of the front door opening 3 and a rear door wind through which air for blowing out the rear door opening 4 flows The road 72 is separated.

As shown in FIG. 5, the duct 20 is provided with an air passage switching mechanism 30 for switching the air passage leading from the blower 10 to the front seat door side air path 71 or the rear seat door side air path 72. . The air passage switching mechanism 30 includes an air passage switching door 31 rotatably provided inside the duct 20 and an actuator for driving the air passage switching door 31. The actuator is provided outside the duct 20. In FIG. 5, the air passage switching mechanism 30 communicates the blower 10 with the front seat door side air passage 71 on the right side of the vehicle, and blocks the blower 10 from the front seat door side air passage 71 on the left side of the vehicle. It is shut off from the air passage 72 on the rear seat door side. Thereby, as shown by arrow AF1, the air ventilated from the blower 10 flows to the front seat door side air passage 71 on the right side of the vehicle.

As shown in FIG. 1, FIG. 4 and FIG. 5, a plurality of blowout nozzles 40 are provided in the front seat door side air passage 71 and the rear seat door side air passage 72 respectively. The plurality of blowout nozzles 40 are provided side by side or intermittently in the vertical direction of the support duct 22. The blowout nozzle 40 can adopt nozzles of various shapes such as a slit nozzle or a circular nozzle. The plurality of blowout nozzles 40 blow out the air flowing through the air passage inside the duct 20 to the outside of the front seat door opening 3 or the rear seat door opening 4 at a predetermined angle, thereby preventing foreign matter from entering the vehicle compartment It generates an air flow. In the following description, among the plurality of blowout nozzles 40, the plurality of blowout nozzles 40 that blow out air at a predetermined angle to the outside of the front seat door opening 3 will be referred to as the front seat side blowout nozzle group 41. Further, among the plurality of blowout nozzles 40, the plurality of blowout nozzles 40 that blow out air at a predetermined angle to the outside of the rear seat door opening 4 will be referred to as a rear seat side blowout nozzle group 42. That is, the plurality of blowout nozzles 40 of the present embodiment have a front seat side blowout nozzle group 41 and a rear seat side blowout nozzle group 42.

As shown in FIG. 1, FIG. 2, FIG. 8 and FIG. 9, for example, when the door 100 provided at the front door opening 3 opens at a predetermined angle, the front seat side blowout nozzle group 41 An air flow is blown toward the opposite door end as shown by arrow AF2. This prevents foreign objects such as mosquitoes from entering the vehicle compartment from the front seat door opening 3.

As shown in FIG. 1, FIG. 2, FIG. 10 and FIG. 11, for example, the rear seat side blowout nozzle group 42 is a door hinge when the door 101 provided at the rear seat door opening 4 is opened at a predetermined angle. An air flow is blown out toward the space between the opposite door end and the C pillar 7 as shown by the arrow AF3. This prevents foreign objects such as mosquitoes from entering the vehicle compartment from the rear seat door opening 4.

The control device 50 includes a processor that performs control processing and arithmetic processing, a ROM that stores programs and data, a microcomputer that includes a storage unit such as a RAM, and peripheral circuits thereof. The storage unit of the control device 50 is configured of a non-transitional substantial storage medium. The control device 50 performs various control processing and arithmetic processing based on the program stored in the storage unit, and controls the operation of each device connected to the output port.

As shown in FIG. 6, the control device 50 is connected to the engine control device 51, the battery control device 52, etc. through CAN (abbreviation of Controller Area Network) or the like. The control device 50 receives vehicle speed information, information related to battery voltage, and the like. Further, to the control device 50, a signal regarding door opening / closing transmitted from a door opening / closing detection device 53 provided at an opening of each door of the vehicle is input. The control device 50 can control the operation of the blower 10, the air path switching mechanism 30, the front air conditioner unit 8, and the like based on the signals.

Next, control processing performed by the control device 50 provided in the air blowing device 1 will be described with reference to the flowchart in FIG. 7.
In step S10, the control device 50 determines, based on the signal transmitted from the door open / close detection device 53, which position of the plurality of

doors

100, 101 provided in the vehicle has been opened. When detecting that one of the

doors

100 and 101 of the vehicle is opened, the control device 50 shifts the process to step S20.

In step S20, the control device 50 causes the air blown from the blower 10 to flow to the front air passage 71 or the air passage 72 corresponding to the

door openings

3 and 4 in which the

doors

100 and 101 are opened. Thus, the air passage switching mechanism 30 is operated.
Subsequently, in step S30, the control device 50 operates the blower 10. As a result, air flows from the blower 10 to the front seat door air passage 71 or the rear door air passage 72 corresponding to the

door openings

3 and 4 where the

doors

100 and 101 are opened, to the

door openings

3 and 4. Air is blown out from the corresponding blowing nozzle 40.

Specifically, in FIGS. 1 and 2, air flows from the blower 10 to the front seat door side air passage 71 on the right side of the vehicle and the rear seat door side air passage 72 on the right side of the vehicle. The air is blown out to the outside of the

door openings

3 and 4 from both the rear seat side blowout nozzle group 42 and the rear seat side blowout nozzle group 42.
In FIGS. 8 and 9, air flows from the blower 10 to the front seat door side air passage 71 on the right side of the vehicle and air is blown out from the front seat side outlet nozzle group 41 on the right side of the vehicle to the outside of the door opening 3 Is shown.
In FIGS. 10 and 11, air flows from the blower 10 to the rear door side air passage 72 on the right side of the vehicle and air is blown out from the rear seat side outlet nozzle group 42 on the right side of the vehicle to the outside of the door opening 4 Is shown.

By the way, when the blower 10 sucks the air in the vehicle compartment and the air is blown out from the blowout nozzle 40 through the duct 20 to the outside of the vehicle, the pressure in the vehicle compartment becomes negative and the air blown out from the blowout nozzle 40 again It is conceivable that a circulating flow may occur such as being sucked into the room. And there is a possibility that foreign substances, such as a mosquito, may enter into a vehicle interior with the circulation flow. In order to prevent negative pressure in the passenger compartment, an intake passage 80 for introducing outside air into the passenger compartment may be provided separately from the front seat door opening 3 and the rear seat door opening 4. In the present embodiment, the outside air intake port 81 of the front air conditioner unit 8 is used as the outside air introduction port of the intake path 80.

Therefore, in the present embodiment, the control device 50 operates the front air conditioner unit 8 in the outside air mode in step S40 following step S30 in FIG. 7. At this time, the control device 50 controls the air blowing device so that the amount of air blown into the vehicle compartment from the outside of the vehicle by the front air conditioner unit 8 becomes larger than the amount of air blown out of the vehicle cabin from the vehicle compartment by the blower 10 of the air blowing device 1. 1 and drive the front air conditioner unit 8. Specifically, the control device 50 controls the driving of the blower 10 of the air blowing device 1 and a blower (not shown) provided in the front air conditioner unit 8. As a result, even if the air blower 10 of the air blowing device 1 operates and air in the vehicle compartment is blown out of the vehicle from the blowout nozzle 40, negative pressure in the vehicle compartment is prevented. Therefore, the air blown out from the blowout nozzle 40 is prevented from being sucked into the vehicle compartment again, so that foreign matter such as mosquito can be prevented from intruding into the vehicle compartment. Generally, a filter is provided at the outside air intake port 81 of the front air conditioner unit 8, so that foreign matter such as mosquito can be prevented from entering the vehicle interior from the front air conditioner unit 8.

Next, in step S50, the control device 50 determines, based on the signal transmitted from the door open / close detection device 53, whether or not the

open doors

100 and 101 are closed. When the control device 50 detects that all the

doors

100 and 101 of the vehicle are closed, the control device 50 shifts the process to step S60.
In step S60, the control device 50 stops the blower 10. Thereby, the blowout of air from the blowout nozzle 40 is stopped.

Subsequently, at step S70, the control device 50 determines whether the front air conditioner unit switch is off. When the controller 50 determines that the front air conditioner unit switch is off, the process proceeds to step S80, and the operation of the front air conditioner unit 8 is stopped.
On the other hand, when the controller 50 determines in step S70 that the front air conditioner unit switch is on, the process proceeds to step S90, and the front air conditioner unit 8 is operated continuously.

The air blowing device 1 of the present embodiment described above has the following effects.
(1) In the present embodiment, the blower 10 is closer to the distance between the B-pillar 6 and the blower 10 than the distance between the A-pillar 5 and the blower 10 in the longitudinal direction of the vehicle and from the distance between the C-pillar 7 and the blower 10 It is provided in the near position.
As a result, the distance between the blowout nozzle 40 and the blower 10 becomes short, and the duct 20 communicating between the two becomes short, so that the air flow resistance of the duct 20 can be reduced. Therefore, the amount of air blown out from the blowout nozzle 40 increases. Therefore, the air blowing device 1 can obtain the wind speed and the air volume necessary to reduce the intrusion of foreign substances such as mosquitoes from the front seat door opening 3 or the rear seat door opening 4 into the vehicle cabin.

Further, since the air blowing device 1 does not have a compressor or an air tank as in Patent Document 1 described above, it is possible to reduce the size of the device and to reduce the manufacturing cost.
Furthermore, in the air blowing device 1, the duct 20 provided with the blowing nozzle 40 is provided along the B-pillar 6 to allow the plurality of blowing nozzles 40 to connect both the front seat door opening 3 and the rear seat door opening 4. I can blow out the air.

(2) In the present embodiment, the blower 10 is provided at a position away from the top of the head of the occupant 2 seated in the seat of the vehicle among the ceiling of the vehicle.
Thereby, the clearance between the head of the occupant 2 seated in the seat of the vehicle and the vehicle ceiling can be secured.

(3) In the present embodiment, the blower 10 is provided at the central portion in the vehicle width direction of the ceiling of the vehicle.
As a result, air can be sent by a single fan 10 to the plurality of blowing nozzles 40 provided along the B pillars 6 on the left and right in the vehicle width direction. Further, since the range in which the blower 10 blocks the forward visibility of the occupant 2 seated in the second and subsequent rows of the vehicle is reduced, the influence of the blower 10 on the forward visibility of the occupant 2 can be reduced.

(4) In the present embodiment, the air blowing device 1 is provided with an intake path 80 for introducing outside air into the vehicle compartment, separately from the front seat door opening 3 and the rear seat door opening 4.
As a result, even if the air inside the vehicle compartment is blown out of the vehicle from the blowout nozzle 40, the outside air is introduced into the vehicle compartment via the intake passage 80, so negative pressure in the vehicle compartment can be prevented. Therefore, it is possible to prevent the occurrence of a circulating flow in which the air blown out from the blowout nozzle 40 is again sucked into the vehicle compartment, so that the entry of foreign matter such as mosquito can be prevented.

(5) In the present embodiment, the intake path 80 is the outside air intake port 81 of the front air conditioner unit 8.
By the way, when a hole is made in the vehicle body in order to provide the intake path 80 in the vehicle, the rigidity of the vehicle body may be reduced. On the other hand, if the outside air intake port 81 of the front air conditioner unit 8 is used as the intake path 80, the intake path 80 can be provided in the vehicle without making a hole in the vehicle body.

(6) In the present embodiment, the control device 50 operates the front air conditioner unit 8 in the open air mode in conjunction with the operation of the blower 10.
As a result, even if the air in the vehicle compartment is blown out from the blowout nozzle 40 by the operation of the blower 10, the front air conditioner unit 8 operates in the outside air mode and the outside air is introduced into the vehicle compartment. It is prevented from becoming pressure. Therefore, it is possible to prevent the occurrence of a circulating flow in which the air blown out from the blowout nozzle 40 is again sucked into the vehicle compartment, so that the entry of foreign matter such as mosquito can be prevented. Generally, a filter is provided in the outside air introduction path of the front air conditioner unit 8, so that foreign objects such as mosquitoes are prevented from entering from the front air conditioner unit 8.

(7) In the present embodiment, the amount of air blown from the outside of the vehicle into the vehicle compartment by the front air conditioner unit 8 is larger than the amount of air blown out of the vehicle from the vehicle interior by the blower 10.
As a result, when air in the vehicle compartment is blown out from the blowout nozzle 40, negative pressure in the vehicle compartment can be reliably prevented. Therefore, external air can be prevented from entering the vehicle compartment from unintended places, so that the entry of foreign matter such as mosquito can be prevented.

Second Embodiment
The second embodiment will be described. The second embodiment is the same as the first embodiment except that the mounting position of the blower 10 is changed with respect to the first embodiment, and the other parts are the same as the first embodiment, so only the parts different from the first embodiment will be described. .

As shown in FIGS. 12 to 14, in the second embodiment, the blower 10 is provided in front of the ceiling duct 21 in the vehicle. In the second embodiment as well, as in the first embodiment, the blower 10 is provided at a position on the ceiling of the vehicle avoiding the top of the head of the occupant 2 seated in the seat of the vehicle. Moreover, the blower 10 is provided in the center part in the vehicle width direction among the ceilings of a vehicle.

Also in the second embodiment, in the blower 10, the distance between the B pillar 6 and the blower 10 is closer than the distance between the A pillar 5 and the blower 10 and closer than the distance between the C pillar 7 and the blower 10 in the vehicle longitudinal direction. Provided in Specifically, as viewed in the vehicle width direction, the distance between the rear end of the blower 10 and the B pillar 6 is the distance indicated by the arrow D4. The distance between the front end of the blower 10 and the A-pillar 5 is the distance indicated by the arrow D5. The distance between the rear end of the blower 10 and the C-pillar 7 is the distance indicated by the arrow D6. The distance indicated by arrow D4 is smaller than the distance indicated by arrow D5 and smaller than the distance indicated by arrow D6. Therefore, it can be said that the distance between B pillar 6 and air blower 10 is closer than the distance between A pillar 5 and air blower 10 and is closer than the distance between C pillar 7 and air blower 10 in the vehicle longitudinal direction.

In FIG. 14, the air passage switching door 31 provided in the air passage switching mechanism 30 communicates the blower 10 with the front seat door side air passage 71 on the right side of the vehicle, and the blower 10 and the front seat door side air passage 71 on the left side of the vehicle And the rear air passage 72 on the rear side of the vehicle. Thereby, as shown by arrow AF4, the air ventilated from the blower 10 flows to the front seat door side air passage 71 on the right side of the vehicle. Note that the air passage switching mechanism 30 controls the air blown from the blower 10 by opening and closing control of the air passage switching door 31, and the air passage 71 on the front seat door on the right or left side of the vehicle or the rear seat on the right or left side of the vehicle It is possible to flow in the door air passage 72.
The second embodiment described above can also achieve the same effects as the first embodiment.

Third Embodiment

(Summary)
According to a first aspect, shown in part or all of the above embodiments, the air blowing device is mounted on a vehicle having an A-pillar, a B-pillar and a C-pillar. The A-pillar is provided on the front side of the front seat door opening corresponding to the front seat. The B-pillar is provided between the rear door opening and the front door opening corresponding to the second row of seats from the front. The C-pillar is provided behind the rear seat door opening. The air blowing device comprises a blower, a duct and a plurality of blowing nozzles. The blower blows the air drawn in from the vehicle compartment. The duct is provided along the B-pillar, and the air blown from the blower flows. The plurality of blowout nozzles blow out the air flowing through the duct to the outside of the front seat door opening or the rear seat door opening at a predetermined angle to generate an air flow that prevents foreign matter from entering the vehicle interior. Here, in the longitudinal direction of the vehicle, the distance between the B-pillar and the blower is closer than the distance between the A-pillar and the blower and is closer than the distance between the C-pillar and the blower.

According to the second aspect, the blower is provided at a position on the ceiling of the vehicle avoiding the upper portion of the head of the occupant seated in the seat of the vehicle.
According to this, it is possible to secure the clearance between the occupant's head seated in the seat of the vehicle and the vehicle ceiling.

According to the third aspect, the blower is provided at the central portion in the vehicle width direction of the ceiling of the vehicle.
According to this, it is possible to send air by a single fan to the plurality of blowout nozzles provided in the B pillars on the left and right in the vehicle width direction. Further, since the range in which the blower blocks the forward visibility of the occupant seated in the second and subsequent rows of the vehicle is reduced, the influence of the blower on the forward visibility of the occupant can be reduced.

According to a fourth aspect, the blower is provided under the front seat of the vehicle.
According to this, it is possible to utilize the dead space under the front seat of the vehicle to secure the vehicle interior space. Further, by providing the blower under the front seat of the vehicle, the distance between the blower nozzle and the blowout nozzle installed on the B-pillar becomes short. Therefore, it is possible to shorten the duct connecting the blowout nozzle and the blower and to reduce the ventilation resistance of the duct. Therefore, this air blowing device can increase the wind speed and the air volume blown out from the blowing nozzle, and can obtain the wind speed and the air volume necessary to reduce the entry of foreign matter such as mosquito into the vehicle compartment.

According to the fifth aspect, the air blowing device further includes an air intake path for introducing outside air into the vehicle compartment, separately from the front seat door opening and the rear seat door opening.
By the way, when the blower sucks the air in the vehicle compartment and the air is blown out from the blowout nozzle to the outside of the vehicle through the duct, the pressure in the vehicle compartment becomes negative and the air blown out from the blowout nozzle is sucked into the vehicle compartment again. It is conceivable that circulation flow will occur. And there is a possibility that foreign substances, such as a mosquito, may enter into a vehicle interior with the circulation flow.
Therefore, the air blowing device is provided with an intake path for introducing the outside air into the vehicle compartment. As a result, even if the air inside the vehicle compartment is blown out from the blowout nozzle to the outside of the vehicle, the outside air is introduced into the vehicle compartment via the intake path, so that the vehicle compartment is prevented from being under negative pressure. Accordingly, it is possible to prevent the occurrence of a circulating flow in which the air blown out from the blowout nozzle is again sucked into the vehicle compartment, so that the entry of foreign matter such as mosquito can be prevented.

According to the sixth aspect, the air blowing device is mounted on a vehicle provided with a front air conditioner unit. The intake path is an outside air intake port of the front air conditioner unit.
By the way, when a hole is made in the vehicle body in order to provide the intake path in the vehicle, there is a possibility that the rigidity of the vehicle body may be reduced. Therefore, this air blowing device uses an outside air intake port of the front air conditioner unit as an intake path. Thus, it is possible to provide the intake path in the vehicle without making a hole in the vehicle body.

According to the seventh aspect, the air blowing device further includes a control device that controls the operation of the blower and the operation of the front air conditioner unit. The controller operates the front air conditioner unit in the open air mode in conjunction with the operation of the blower.
According to this, even if the blower operates and air in the compartment is blown out from the blowout nozzle, the front air conditioning unit operates in the outside air mode and the outside air is introduced into the compartment, so the pressure inside the compartment is negative. Being prevented. Accordingly, it is possible to prevent the occurrence of a circulating flow in which the air blown out from the blowout nozzle is again sucked into the vehicle compartment, so that the entry of foreign matter such as mosquito can be prevented. In general, a filter is provided in the outside air introduction path of the front air conditioner unit, so that foreign matter such as mosquito can be prevented from entering from the front air conditioner unit.

According to the eighth aspect, the amount of air blown from the outside of the vehicle into the vehicle compartment by the front air conditioning unit is larger than the amount of air blown out of the vehicle from the vehicle interior by the blower.
According to this, when the air inside the vehicle compartment is blown out from the blowout nozzle to the outside of the vehicle, it is possible to reliably prevent the vehicle compartment from becoming negative pressure. Therefore, external air can be prevented from entering the vehicle compartment from unintended places, so that the entry of foreign matter such as mosquito can be prevented.
