Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In the following embodiments, the same or equivalent parts are denoted by the same reference numerals in the drawings.

(First embodiment)
The air blowing device 10 shown in FIG. 1 is used so as to constitute a part of an air blowing unit included in a duct connected to an air conditioning unit 20 mounted in front of the vehicle. 1 indicates the vehicle up-down direction DR1 as the first direction DR1, the arrow DR2 indicates the vehicle front-rear direction DR2 as the second direction DR2, and the arrow DR3 in FIG. 2 described later is the vehicle as the third direction DR3. The left-right direction DR3, that is, the vehicle width direction DR3 is shown. These three directions DR1, DR2, DR3 are directions intersecting each other, strictly speaking, directions orthogonal to each other.

The air conditioning unit 20 in the present embodiment is a well-known device that is arranged in the instrument panel 70 and blows out the conditioned air whose temperature is adjusted toward the vehicle interior. For example, the air conditioning unit 20 is the same as the air conditioning unit shown in FIG. The air conditioning unit 20 functions as a blower that sends air to the air blowing device 10 with respect to the air blowing device 10. That is, the air blowing device 10 blows out air from the air conditioning unit 20.

The instrument panel 70 has an upper surface 701 and a front portion (not shown). The instrument panel 70 is an instrument panel provided in front of the passenger compartment in the passenger compartment. The instrument panel 70 includes not only the part where the instruments are arranged, but also the entire panel located in front of the front seat (that is, the driver's seat and the passenger seat) in the vehicle interior, including the part that houses the audio and the air conditioner. pointing.

As shown in FIGS. 1 and 2, the air blowing device 10 includes a blowing unit 12 that blows out air that has flowed out of the air conditioning unit 20 into a vehicle interior that is an air conditioning target space, an airflow deflecting door 14 that serves as an airflow operation member, A blow direction adjusting door 16 as a blow direction adjusting member is provided. 2 is a cross-sectional view taken along the line II-II in FIG.

The blowout part 12 is formed with a blowout port 121 through which air from the air conditioning unit 20 is blown into the vehicle compartment and a blowout passage 122. An outlet passage 122 is connected to the outlet 121. In other words, the outlet 121 is also the downstream edge of the outlet passage 122 in the outlet air flow direction. The blown air flow direction is the flow direction of the main flow of blown air blown from the blower outlet 121. The blown air flow direction is, for example, that shown in FIG. As shown by the arrow ARa in FIG. Further, the flow direction of the blown air is changed by the airflow deflecting door 14 and the blowing direction adjusting door 16 on the downstream side of the airflow deflecting door 14.

The blower outlet 121 opens upward in the vehicle vertical direction DR1. That is, at least the downstream end portion of the blowout passage 122 on the downstream side of the blown air flow is a passage in a direction along the vehicle vertical direction DR1. And the blower outlet 121 has comprised the rectangular shape which made the vehicle width direction DR3 the longitudinal direction. In addition, the said blowing air flow downstream is the downstream of a blowing air flow direction, and conversely, the upstream of a blowing air flow direction is called blowing air flow upstream.

Further, the air outlet 121 is provided near the front of the vehicle on the upper surface 701 of the instrument panel 70 provided in the vehicle interior. In short, the air outlet 121 is disposed on the front side (in other words, the vehicle front side) in the vehicle front-rear direction DR2 with respect to a driver seat and a passenger seat (not shown) installed in the passenger compartment. And the blowing part 12 in which the blower outlet 121 was formed comprises a part of instrument panel 70, ie, the part around the blower outlet 121. As shown in FIG.

The blowout passage 122 guides the air from the air conditioning unit 20 to the blowout port 121. The cross section of the air passage 122 of the air outlet 122 perpendicular to the direction of the air flow in the air outlet 122 has a rectangular shape with the vehicle width direction DR3 as the longitudinal direction, like the air outlet 121. Further, since the blowout passage 122 is connected to the upward blowout port 121, the central axis CL1 of the blowout passage 122 as one axis is oriented along the vehicle vertical direction DR1. Note that “along” used in the description of the present embodiment is not limited to the case where A is completely parallel to or coincides with B if the expression “A is along B” is described as an example. The term “along” means that A is slightly inclined with respect to B and that the distance between A and B is somewhat uneven.

Further, the blowout part 12 has a passage inner wall surface 123 facing the blowout passage 122. That is, the outlet passage 122 is formed by being surrounded by the inner wall surface 123 of the passage.

The blowout part 12 has a part of the inner wall surface 123 of the passage as a guide wall surface 123a for guiding the air blown out from the blowout port 121. Specifically, the guide wall surface 123a is located on one side (specifically, the rear side) of the vehicle front-rear direction DR2 in the passage inner wall surface 123 and from the peripheral portion 124 of the outlet 121 to the upstream side of the blown air flow. It is an extended part.

The guide wall surface 123a has a shape that expands the upward blowing passage 122 toward the rear side (in other words, the vehicle rear side) in the vehicle longitudinal direction DR2 toward the downstream side of the blown air flow. Specifically, the guide wall surface 123a is formed of a curved surface that warps rearward in the vehicle longitudinal direction DR2. That is, the guide wall surface 123a is curved so that the outlet passage 122 side is a convex side, and the outlet passage 122 is expanded toward the rear side toward the downstream side of the outlet air flow. In short, the guide wall surface 123a extends from the bottom to the top while bending toward the vehicle rear side. Note that since the blown air flowing in the blowout passage 122 flows upward along the central axis CL1 of the blowout passage 122 as indicated by the arrow ARa, in this embodiment, the blown air flow downstream side is the upper side in the vehicle vertical direction DR1. In other words.

Further, the guide wall surface 123a is formed to be continuous with the upper surface 701 of the instrument panel 70. The guide wall surface 123a is for guiding the high-speed airflow flowing out from the rear side passage 122a included in the outlet passage 122 to the rear side in the vehicle front-rear direction DR2 along the guide wall surface 123a.

Since the blowing part 12 has the guide wall surface 123a in this way, if the blowing air blown out from the outlet 121 flows along the guide wall surface 123a, it blows out toward the occupant seated in the driver seat or the passenger seat. Is done. On the other hand, if the blown air does not follow the guide wall surface 123a, the blown air is blown to the upper side which is the opening direction of the blower outlet 121. That is, in that case, the blown air is blown out toward the front window 72 provided on the upper side with respect to the blower outlet 121.

As shown in FIGS. 1 and 2, the airflow deflection door 14 is disposed in the outlet passage 122, and the operation of the airflow deflection door 14 is controlled by a control signal output from a control device (not shown). Since the airflow deflecting door 14 is disposed in the blowing passage 122, two

parallel air passages

122a and 122b are formed as a part of the blowing passage 122. Specifically, the airflow deflecting door 14 blows out a rear side passage 122a (that is, one side passage 122a) as a first passage located on the rear side that is one side with respect to the airflow deflecting door 14 in the vehicle longitudinal direction DR2. It is formed as a part of the passage 122. At the same time, the airflow deflector door 14 is also a front passage 122b (that is, the other passage 122b) as a second passage located on the front side that is the other side of the airflow deflector door 14 in the vehicle longitudinal direction DR2. Form as part of.

The airflow deflecting door 14 is a plate-like turning member that turns around the turning axis CL3 along the vehicle width direction DR3, and is a turning door in short. Specifically, the airflow deflector door 14 has a deflector door pivot shaft 141 centered on the pivot axis CL3, and extends from the deflector door pivot shaft 141 to both sides in the radial direction and is fixed to the deflector door pivot shaft 141. Plate door part 142.

The plate door portion 142 has a length that extends, for example, over the entire length of the outlet passage 122 in the vehicle width direction DR3. Therefore, the plate door part 142 is arrange | positioned so that the vehicle width direction DR3 may be made into a longitudinal direction. The plate door part 142 has, for example, a rectangular flat plate shape.

As shown in FIG. 1, the airflow deflection door 14 increases or decreases the passage cross-sectional area of the rear side passage 122 a and the passage cross-sectional area of the front side passage 122 b in accordance with the rotation angle about the rotation axis CL <b> 3. . For example, the airflow deflection door 14 increases or decreases the passage cross-sectional area of the rear-side passage 122a by changing the rotation angle of the airflow deflection door 14. The airflow deflection door 14 increases or decreases the airflow velocity of the rear passage 122a by changing the cross-sectional area of the rear passage 122a in accordance with the rotation of the airflow deflection door 14.

More specifically, the airflow deflecting door 14 is selectively switched between the first state and the second state by rotating around the rotation axis line CL3. In the first state, the passage cross-sectional area of the rear side passage 122a is made smaller than the area threshold value experimentally determined in advance by the airflow deflecting door 14. As a result, a high-speed airflow (that is, a jet) blown into the vehicle interior along the guide wall surface 123a due to the Coanda effect is formed in the rear-side passage 122a, and a low-speed airflow slower than the high-speed airflow is generated in the front-side passage 122b. Formed.

In short, the airflow deflecting door 14 has its rear side passage formed by the Coanda effect obtained according to the airflow velocity of the air flowing through the rear side passage 122a when the state of the airflow of the blowout passage 122 is the first state. The flow of air flowing through 122a is caused to follow the guide wall surface 123a. In the first state, the low-speed airflow in the front-side passage 122b is attracted to the high-speed airflow in the rear-side passage 122a by the Coanda effect. Therefore, when the air flow in the rear side passage 122a follows the guide wall surface 123a in this way, the air blown out from the air outlet 121 is bent rearward in the vehicle front-rear direction DR2.

On the other hand, the second state of the air flow in the blowing passage 122 is a state in which an air flow different from the first state is formed in the blowing passage 122. For example, in the second state, the passage cross-sectional area of the rear side passage 122a is enlarged as compared with that in the first state. In short, the degree of throttling with respect to the flow of air flowing through the rear passage 122a becomes loose. Thereby, in the second state, the flow velocity of the airflow formed in the rear side passage 122a is lower than that in the first state. The airflow in the rear passage 122 a hardly follows the guide wall surface 123 a, and the blown air blown out from the blowout port 121 flows upward along the central axis CL <b> 1 of the blowout passage 122.

The airflow deflecting door 14 only needs to be able to deflect the airflow velocity between the rear side passage 122a and the front side passage 122b, and needs to be formed by completely separating the rear side passage 122a and the front side passage 122b. There is no.

As shown in FIGS. 1 and 2, the blowing direction adjusting door 16 is provided inside the blowing portion 12 and adjusts the blowing direction of the air blown from the blowing port 121 in the vehicle width direction DR3. In other words, the blow direction adjusting door 16 adjusts the width direction component along the vehicle width direction DR3 among the three direction components constituting the air blow direction. The three-direction components are the up-down direction component as the first direction component along the vehicle up-down direction DR1, the front-rear direction component as the second direction component along the vehicle front-rear direction DR2, and the above-mentioned as the third direction component. It is a width direction component. The said blowing direction is the blowing air flow direction in the blower outlet 121 if it says in detail.

For example, the blow direction adjusting door 16 adjusts the blow direction so that the air blow direction is obliquely upward as indicated by the arrows ARb and ARc in FIG. 2 according to the rotation angle of the blow direction adjusting door 16. To do. That is, in FIG. 2, the air blowing direction is represented by an arrow ARb and an arrow ARc.

Specifically, a plurality of blowing direction adjusting doors 16 are provided. The plurality of blowing direction adjusting doors 16 constitute a louver, and are arranged side by side in the vehicle width direction DR3 with a space therebetween. As shown in FIGS. 1 and 2, the plurality of blow direction adjusting doors 16 are all disposed downstream of the air flow deflecting door 14 in the flow direction of the blown air blown from the blower outlet 121. Yes. The downstream side is the upper side in the vehicle vertical direction DR1 in this embodiment.

And the blowing direction adjustment door 16 has the air guide part 161 and the rotating shaft 162. FIG. The air guide portion 161 has a substantially rectangular flat plate shape with the longitudinal direction DR2 of the vehicle as a longitudinal direction. The air guide portion 161 is formed so as to extend from the rotation shaft 162 to one side and the other side in the radial direction of the rotation shaft 162.

And the air guide part 161 of the blowing direction adjustment door 16 has an upstream end 161c positioned upstream in the air flow direction along the air guide surface 161a indicated by the arrows ARb and ARc, and the air guide surface 161a. A downstream end 161d located on the downstream side in the air flow direction. In other words, the upstream end 161c of the air guide portion 161 is located on the opposite side of the air guide portion 161 from the downstream end 161d.

Air guide surfaces 161 a are formed on both sides of the air guide portion 161 in the thickness direction. The air guide surface 161a can guide the blown air because the blown air blown from the blowout port 121 flows along the air guide surface 161a as indicated by the arrows ARb and ARc.

The rotation shaft 162 of the blowing direction adjusting door 16 is provided with the vehicle longitudinal direction DR2 as an axial direction. The rotating shaft 162 is fixed with respect to the air guide portion 161. The fact that the pivot shaft 162 is provided with the vehicle longitudinal direction DR2 as the axial direction is not limited to the fact that the axial direction of the pivot shaft 162 completely coincides with the vehicle longitudinal direction DR2, and the axial direction is the vehicle longitudinal direction. It also means that it is slightly inclined with respect to DR2.

Rotating shaft 162 is connected to, for example, an electric actuator and is rotated by the actuator. At the same time, the rotation shaft 162 rotates the air guide surface 161 a formed in the air guide portion 161. If the air guide surface 161 a rotates in this way, the guide surface angle α 1 formed by the air guide surface 161 a with respect to the central axis CL 1 of the outlet passage 122 changes accordingly. And the blowing direction adjustment door 16 adjusts the blowing direction of the air which blows off from the blower outlet 121 to the vehicle width direction DR3 according to the guide surface angle (alpha) 1. Since the center axis CL1 of the blowout passage 122 is oriented along the vehicle vertical direction DR1, the guide surface angle α1 formed by the air guide surface 161a with respect to the center axis CL1 is such that the air guide surface 161a is in the vehicle vertical direction. It may be paraphrased as guide surface angle α1 formed with respect to DR1.

Also, the blowing direction adjusting door 16 is supported at both ends. That is, as shown in FIG. 1, the rotation shaft 162 is rotatably supported with respect to the blowing portion 12 on the rear side in the vehicle longitudinal direction DR <b> 2 with respect to the air guide portion 161 of the blowing direction adjusting door 16. . At the same time, the rotating shaft 162 is supported so as to be rotatable with respect to the blowing portion 12 even on the front side in the vehicle longitudinal direction DR2 with respect to the air guide portion 161.

Further, as shown in FIG. 1, the air guide portion 161 of the blowing direction adjusting door 16 has a guide side edge 161b on the rear side in the vehicle longitudinal direction DR2, that is, on the guide wall surface 123a side. The guide side edge 161b has a curved shape corresponding to the guide wall surface 123a.

Specifically, the guide-side edge 161b has a shape along the guide wall surface 123a when the air guide surface 161a is vertically oriented along the vehicle vertical direction DR1, and is spaced from the guide wall surface 123a. It is provided so as to be free. Naturally, since the air guide portion 161 should not interfere with the guide wall surface 123a, the guide-side edge 161b is formed regardless of the rotation angle of the passage inner wall surface 123 within a previously permitted permissible rotation range. There is a gap between the guide wall surface 123a and the guide wall surface 123a. Since the inner wall surface 123 of the passage is a part of the air guide portion 161, the allowable rotation range of the inner wall surface 123 of the passage is also the allowable rotation range of the air guide portion 161. In addition, the allowable rotation range of the air guide portion 161 is narrower than 180 °, and the upstream end 161c of the air guide portion 161 no matter which rotation angle the air guide portion 161 rotates within the allowable rotation range. And the position of the downstream end 161d are not reversed in the vehicle vertical direction DR1.

In the air blowing device 10 configured as described above, the blowing direction of the air blown from the blower outlet 121 is adjusted by the airflow deflecting door 14 in the vehicle longitudinal direction DR2. At the same time, the blowing direction is adjusted by the blowing direction adjusting door 16 in the vehicle width direction DR3.

As described above, according to the present embodiment, as shown in FIGS. 1 and 2, the blowing direction adjusting door 16 is in the main flow direction (ie, the blowing air flow direction) of the blown air blown from the blower outlet 121. The air flow deflecting door 14 is disposed on the downstream side. Therefore, it is possible to give the blowing direction adjusting door 16 the role of preventing the entry of foreign matter from the blowing port 121 into the blowing unit 12. Therefore, it is not necessary to arrange a member corresponding to the cover of the air blowing device described in Patent Document 1 in the vicinity of the blowout port 121. Therefore, there is no disturbance that the air blowing direction adjusted by the blowing direction adjusting door 16 is corrected by the cover, and it is possible to blow air from the blower outlet 121 while maintaining the blowing direction.

Further, as compared with the configuration in which the blowing direction adjusting door 16 is arranged on the upstream side with respect to the airflow deflecting door 14, the direction of the air flowing out from between the blowing direction adjusting doors 16 is less likely to be corrected by the passage inner wall surface 123. Therefore, also in this respect, it is easy to increase the blowing direction adjustment effect by the blowing direction adjustment door 16.

In addition, according to the present embodiment, the air blowing described in Patent Document 1 is provided by providing the blowing direction adjusting door 16 with the role of preventing the entry of foreign matter from the blowing outlet 121 into the blowing portion 12 as described above. A member corresponding to the cover of the apparatus can be eliminated. Therefore, it is possible to reduce the size of the air blowing device 10 in the axial direction of the central axis CL <b> 1 of the blowing passage 122 as compared with the configuration having the cover. That is, in FIG. 1, the air blowing device 10 can be downsized in the vehicle vertical direction DR1. As a result, the vehicle mountability of the air blowing device 10 can be improved.

Moreover, according to this embodiment, as shown in FIG. 1 and FIG. 2, the blowing direction adjusting door 16 has an air guiding portion 161a formed with an air guiding surface 161a along which the blown air blown from the blower outlet 121 flows. 161 and a rotation shaft 162. The rotation shaft 162 is provided with the vehicle longitudinal direction DR2 as an axial direction, and is fixed to the air guide portion 161 to rotate the air guide surface 161a. And the blowing direction adjustment door 16 changes the blowing direction of the air blown from the blower outlet 121 to the vehicle width direction DR3 according to the guide surface angle α1 formed by the air guide surface 161a with respect to the central axis CL1 of the blowout passage 122. adjust. Therefore, it is possible to obtain a function of adjusting the blowing direction to the vehicle width direction DR3 while making the blowing direction adjusting door 16 simple.

Further, according to the present embodiment, as shown in FIGS. 1 and 2, the guide-side edge 161b of the air guide portion 161 is when the air guide surface 161a is oriented along the vehicle vertical direction DR1. It has a shape along the guide wall surface 123a and is provided so as to be spaced from the guide wall surface 123a. Therefore, it is possible for the blow direction adjusting door 16 to adjust the blow direction in the vehicle width direction DR3 to the air flowing in the vicinity of the guide wall surface 123a.

Further, according to the present embodiment, as shown in FIG. 2, a plurality of blowing direction adjusting doors 16 are provided, and the plurality of blowing direction adjusting doors 16 are arranged side by side in the vehicle width direction DR3 with an interval therebetween. ing. Therefore, it is easy to strongly obtain the action of the blow direction adjusting door 16 for adjusting the blow direction in the vehicle width direction DR3 as compared with the configuration having one blow direction adjusting door 16. Furthermore, it is also easy to obtain a great effect of preventing the entry of foreign matter from the outlet 121 into the outlet 12 by the outlet direction adjusting door 16.

(Second Embodiment)
Next, a second embodiment will be described. In the present embodiment, differences from the first embodiment will be mainly described. Further, the same or equivalent parts as those of the above-described embodiment will be described by omitting or simplifying them. The same applies to the third and later embodiments described later.

As shown in FIG. 3 and FIG. 4, in this embodiment, the position of the rotating shaft 162 in the blowing direction adjusting door 16 is different from that in the first embodiment.

Concretely, the air guide part 161 of the blowing direction adjustment door 16 has the upstream end 161c and the downstream end 161d similarly to 1st Embodiment. However, in the present embodiment, unlike the first embodiment, the rotation shaft 162 of the blowing direction adjusting door 16 is fixed to the downstream end 161 d of the air guide portion 161.

That is, the air guide portion 161 of the present embodiment is formed so as to extend from the rotation shaft 162 only on one side of one side and the other side in the radial direction of the rotation shaft 162. This point is different from the first embodiment. And the air guide part 161 rotates in the range which does not exceed the rotating shaft 162 to the downstream in the blowing air flow direction.

For example, the air guide part 161 includes an upstream part 161e shown in FIG. The upstream portion 161e is a portion that occupies the upstream end 161c side in the vehicle vertical direction DR1 with respect to the rotating shaft 162 in the air guide portion 161 when the air guide surface 161a is vertically oriented along the vehicle vertical direction DR1. It is. And the blowing direction adjustment door 16 is arrange | positioned so that the whole upstream part 161e may enter the inside of the blowing part 12, when the air guide surface 161a is vertical. In short, when the air guide surface 161 a is vertically oriented, the entire upstream portion 161 e is located in the blowout portion 12. In FIG. 4, the air guide surface 161 a is slightly inclined with respect to the vertical direction, but the entire upstream portion 161 e included in the air guide portion 161 is located in the blowout portion 12.

According to the above-described embodiment, as shown in FIG. 3, the rotation shaft 162 of the blowing direction adjusting door 16 is fixed to the downstream end 161d of the air guide portion 161 in the air flow direction along the air guide surface 161a. ing. Therefore, the part exposed to the vehicle interior at the outlet 121 of the outlet direction adjusting door 16 can be used as the rotation shaft 162. Therefore, it is possible to prevent foreign matter from entering from the outlet 121 into the outlet 12 with the rotary shaft 162 whose width in the vehicle width direction DR3 does not change even when the outlet direction adjusting door 16 rotates.

That is, for example, the plurality of blowing direction adjustment doors 16 function as louvers that adjust the blowing direction of air, and also function as a protective fence against entry of foreign matters such as falling objects into the blowing portion 12. And the gap of the vehicle width direction DR3 which arises between the blowing direction adjustment doors 16 as the protection fence can be kept constant even if the blowing direction adjustment door 16 rotates.

Further, since the rotation shaft 162 is fixed to the downstream end 161d of the air guide portion 161, the guide side end edge 161b of the air guide portion 161 has the air guide surface 161a vertically oriented along the vehicle vertical direction DR1. When it is, it approaches the guide wall surface 123a most. Therefore, if there is a space between the air guide portion 161 and the guide wall surface 123a with the air guide surface 161a facing up and down, the air guide portion 161 does not interfere with the guide wall surface 123a even if it rotates. Thus, it is easy to arrange the blowing direction adjusting door 16 so as not to interfere with the guide wall surface 123a even if the air guide portion 161 rotates, regardless of the shape of the guide side edge 161b.

Further, according to the present embodiment, as shown in FIG. 4, when the air guide surface 161 a is vertically oriented, the blow direction adjusting door 16 blows out the entire upstream portion 161 e included in the air guide portion 161. It arrange | positions so that it may enter inside the part 12. FIG. Therefore, it is possible to improve the design of the air blowing device 10 by suppressing the amount of protrusion of the blowing direction adjusting door 16 protruding upward from the outlet 121.

In this embodiment, it is possible to obtain the same effects as those of the first embodiment, which are obtained from the configuration common to the first embodiment.

(Third embodiment)
Next, a third embodiment will be described. In the present embodiment, differences from the first embodiment will be mainly described.

As shown in FIG. 5 and FIG. 6, in this embodiment, unlike the first embodiment, the blowing direction adjusting door 16 is supported at one end.

Specifically, the rotation shaft 162 of the blow direction adjusting door 16 is blown out on the other side (that is, the front side) opposite to the one side on the guide wall surface 123a side with respect to the air guide portion 161 in the vehicle longitudinal direction DR2. The part 12 is supported so as to be rotatable.

Therefore, the rotation shaft 162 does not protrude toward the guide wall surface 123a with respect to the air guide portion 161 in the vehicle longitudinal direction DR2. In short, the entire blowing direction adjusting door 16 is spaced from the guide wall surface 123a and is arranged away from the guide wall surface 123a.

According to the present embodiment described above, as shown in FIG. 5, the rotation shaft 162 of the blowing direction adjusting door 16 is opposite to the guide wall surface 123a side (that is, the front side) with respect to the air guide portion 161 in the vehicle longitudinal direction DR2. ) And is supported so as to be rotatable with respect to the blowing portion 12. And the blowing direction adjustment door 16 is arrange | positioned away from the guide wall surface 123a. Therefore, it is possible to make it difficult for the high-speed airflow flowing along the guide wall surface 123a due to the Coanda effect to be separated from the guide wall surface 123a due to being disturbed by the rotation shaft 162 of the blowing direction adjusting door 16 or the like. .

That is, it is possible to provide the blowing direction adjusting door 16 so that the blowing direction adjusting door 16 does not easily affect the Coanda effect that causes the high-speed air flow to follow the guide wall surface 123a. Thereby, it is possible for the high-speed airflow to be easily along the guide wall surface 123a, and the air blowing device 10 can be configured such that the flow of the blowing air is easily bent by the Coanda effect.

In addition, although this embodiment is a modification based on 1st Embodiment, it is also possible to combine this embodiment with the above-mentioned 2nd Embodiment.

(Fourth embodiment)
Next, a fourth embodiment will be described. In the present embodiment, differences from the first embodiment will be mainly described.

7 and 8, in the present embodiment, the position of the rotation shaft 162 in the blowing direction adjusting door 16 and the arrangement of the blowing direction adjusting door 16 with respect to the blowing portion 12 are different from those in the first embodiment.

Concretely, the air guide part 161 of the blowing direction adjustment door 16 has the upstream end 161c and the downstream end 161d similarly to 1st Embodiment. However, in the present embodiment, unlike the first embodiment, the rotation shaft 162 of the blow direction adjusting door 16 is fixed to the upstream end 161 c of the air guide portion 161. And the air guide part 161 rotates in the range which does not exceed the rotating shaft 162 to the upstream in the blowing air flow direction.

For example, the blowing direction adjusting door 16 includes a downstream portion 161f shown in FIG. The downstream portion 161f is a portion that occupies the downstream end 161d side in the vehicle vertical direction DR1 with respect to the rotating shaft 162 in the air guide portion 161 when the air guide surface 161a is vertically oriented along the vehicle vertical direction DR1. It is. When the air guide surface 161a is vertically oriented, the blowout direction adjusting door 16 is entirely opposite to the airflow deflecting door 14 side in the vehicle vertical direction DR1 with respect to the blowout port 121. It arrange | positions so that it may be located on the upper side. In short, when the air guide surface 161 a is vertically oriented, the entire downstream portion 161 f is located outside the blowing portion 12. In FIG. 8, the air guide surface 161 a is slightly inclined with respect to the above vertical direction, but the entire downstream portion 161 f included in the air guide portion 161 is located outside the blowout portion 12.

According to this embodiment, since the blowing direction adjusting door 16 is configured as described above, it is difficult to cause a situation in which the high-speed air current is peeled off from the guide wall surface 123a as in the third embodiment. it can.

Moreover, in the structure of this embodiment, as shown in FIG.7 and FIG.8, after the flow of blowing air is bent along the guide wall surface 123a, the blowing direction adjustment door 16 sets the blowing direction of blowing air to the vehicle width. Adjust in direction DR3. Therefore, it is possible to further eliminate the influence of the blow direction adjusting door 16 on the Coanda effect that bends the flow of blown air, as compared with the third embodiment.

As shown in FIGS. 9 and 10, in this embodiment, the shape of the air guide portion 161 of the blowing direction adjusting door 16 is different from that of the second embodiment.

Concretely, the air guide part 161 of the blowing direction adjustment door 16 has the upstream end 161c and the downstream end 161d similarly to 2nd Embodiment. The upstream end 161c of the air guide portion 161 is located below the rotating shaft 162 in the vehicle vertical direction DR1, that is, the airflow deflection, when the air guide surface 161a is vertically oriented along the vehicle vertical direction DR1. Located on the door 14 side.

Furthermore, in the present embodiment, as shown in FIG. 9, unlike the second embodiment, the upstream end 161c of the air guide portion 161 has a concave shape 161g that is recessed toward the downstream end 161d. The concave shape 161g is recessed so as to be spaced from and correspond to the outer edge 14a of the rotation trajectory of the air flow deflecting door 14 when the air guide surface 161a is in the vertical direction. Yes. In FIG. 10, the air guide surface 161a is inclined with respect to the vehicle vertical direction DR1, but FIG. 9 is illustrated in a state where the air guide surface 161a is oriented vertically along the vehicle vertical direction DR1.

According to the present embodiment, since the air guide portion 161 of the blowing direction adjusting door 16 is configured as described above, mutual interference between the airflow deflecting door 14 and the blowing direction adjusting door 16 can be avoided. And compared with the case where the upstream end 161c of the air guide part 161 does not have the concave shape 161g, it is possible to ensure the air guide surface 161a widely.

In this embodiment, it is possible to obtain the same effect as that of the second embodiment, which is obtained from the configuration common to the second embodiment.
