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

First Embodiment
The air blowing device 10 shown in FIG. 1 is used to form a part of an air blowing portion included in a duct connected to an air conditioning unit 20 mounted on the front of a vehicle. Arrow DR1 in FIG. 1 indicates the vehicle vertical direction DR1 as the first direction DR1, arrow DR2 indicates the vehicle longitudinal direction DR2 as the second direction DR2, and arrow DR3 in FIG. 2 described later indicates 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 and DR3 are directions intersecting each other, and strictly speaking are directions orthogonal to each other.

  The air conditioning unit 20 in the present embodiment is a known device which is disposed in the instrument panel 70 and blows out the temperature-controlled air toward the vehicle compartment. For example, the air conditioning unit 20 is the same as the air conditioning unit shown in FIG. 2 of Patent Document 1. Further, the air conditioning unit 20 functions as an air blower for sending air to the air blowing device 10 with respect to the air blowing device 10. That is, the air blowing device 10 blows the 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 the front of the passenger compartment of the passenger compartment. The instrument panel 70 includes the entire panel located in front of the front seat (i.e., the driver's seat and the passenger's seat) in the vehicle compartment, including not only the portion where instruments are arranged but also the portion for storing audio and air conditioners. pointing.

  As shown in FIG. 1 and FIG. 2, the air blowing device 10 blows out the air that has flowed out of the air conditioning unit 20 into the vehicle compartment that is the space to be air conditioned, an air flow deflection door 14 as an air flow operation member, It has the blowing direction adjustment door 16 as a blowing direction adjustment member. FIG. 2 is a cross-sectional view taken along line II-II of FIG.

  In the blowout portion 12, a blowout port 121 for blowing out the air from the air conditioning unit 20 into the vehicle compartment and a blowout passage 122 are formed. An outlet passage 122 is connected to the outlet 121. In other words, the outlet 121 is also the downstream end edge of the outlet passage 122 in the outlet air flow direction. The blowout air flow direction is the flow direction of the main flow of the blowout air blown out from the blowout port 121, and the blowout air flow direction is, for example, FIG. As shown by arrow ARa in FIG. Further, the blowout air flow direction is changed by the air flow deflection door 14 and the blowout direction adjustment door 16 on the downstream side of the air flow deflection door 14.

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

  Further, the air outlet 121 is provided closer to the front of the vehicle on the upper surface 701 of the instrument panel 70 provided in the vehicle compartment. In short, the blower outlet 121 is disposed on the front side (in other words, on the vehicle front side) in the vehicle longitudinal direction DR2 with respect to a driver seat and a passenger seat (not shown) installed in the vehicle interior. The blowout portion 12 in which the blowout port 121 is formed constitutes a part of the instrument panel 70, that is, a portion around the blowout port 121.

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

  The blowout unit 12 also has a passage inner wall surface 123 facing the blowout passage 122. That is, the blowout passage 122 is formed by being surrounded by the inner wall surface 123 of the passage.

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

  The guide wall surface 123a is shaped to expand the upward blowing passage 122 toward the rear side (in other words, the vehicle rear side) in the vehicle longitudinal direction DR2 as the blow air flow downstream side. In detail, the guide wall surface 123a is configured by a curved surface that is curved rearward in the vehicle longitudinal direction DR2. That is, the guide wall surface 123a is curved so that the blowout passage 122 is convex toward the blowout passage 122 side and the blowout passage 122 is expanded rearward as it goes downstream. In short, the guide wall surface 123a extends upward from the bottom while bending toward the rear of the vehicle. The blowout 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. Therefore, in the present embodiment, the blowout air flow downstream side is the upper side in the vehicle vertical direction DR1. It may be paraphrased.

  Further, the guide wall surface 123 a 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 of the rear side passage 122a included in the blowout passage 122 along the guide wall surface 123a to the rear side in the vehicle longitudinal direction DR2.

  Since the blowout section 12 has the guide wall surface 123a in this manner, if the blowout air blown out from the blowout port 121 flows along the guide wall surface 123a, it blows out toward the occupant seated in the driver's seat or the passenger seat. Be done. On the other hand, the blowout air is blown out upward, which is the opening direction of the blowout port 121, if not along the guide wall surface 123a. 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 blowout port 121.

  As shown in FIGS. 1 and 2, the air flow deflection door 14 is disposed in the blowout passage 122, and the operation of the air flow deflection door 14 is controlled by a control signal output from a control device (not shown). Since the air flow deflection door 14 is disposed in the blowout passage 122, two parallel air passages 122a and 122b are formed as a part of the blowout passage 122. In detail, the airflow deflection door 14 blows out the rear side passage 122a (that is, the one-side passage 122a) as a first passage located on the rear side which is one side with respect to the airflow deflection door 14 in the vehicle longitudinal direction DR2. It is formed as a part of the passage 122. At the same time, the air flow deflecting door 14 also has a front side passage 122b (i.e., the other side passage 122b) as a second passage located on the other side of the air flow deflecting door 14 in the vehicle longitudinal direction DR2. It forms as a part of

  The air flow deflection door 14 is a plate-like pivoting member that pivots about a pivoting axis line CL3 along the vehicle width direction DR3, and is a pivoting door. Specifically, the airflow deflection door 14 is extended from the deflection door pivot shaft 141 having the pivot axis CL3 as a central axis, to both sides in the radial direction from the deflection door pivot shaft 141 and fixed to the deflection door pivot shaft 141 And a plate door portion 142.

  The plate door portion 142 has, for example, a length that extends the entire length of the blowout passage 122 in the vehicle width direction DR3. Therefore, the plate door portion 142 is disposed so that the vehicle width direction DR3 is the longitudinal direction. The plate door portion 142 has, for example, a rectangular flat plate shape.

  Further, as shown in FIG. 1, the air flow deflecting door 14 increases / decreases the passage cross sectional area of the rear side passage 122a and the passage cross sectional area of the front side passage 122b according to the turning angle around the turning axis CL3. . For example, the air flow deflection door 14 increases or decreases the passage cross-sectional area of the rear side passage 122 a by the change in the rotation angle of the air flow deflection door 14. The air flow deflecting door 14 changes the air passage velocity of the rear side passage 122 a by changing the passage cross sectional area of the rear side passage 122 a according to the rotation of the air flow deflection door 14.

  Specifically, the airflow deflection door 14 selectively switches the air flow state of the blowout passage 122 between the first state and the second state by pivoting around the pivot axis CL3. In the first state, the air flow deflecting door 14 makes the passage cross sectional area of the rear side passage 122a smaller than an area threshold value which is experimentally determined in advance. As a result, a high speed air flow (i.e., a jet flow) blown out into the vehicle compartment along the guide wall surface 123a by the Coanda effect is formed in the rear side passage 122a, and a low speed air flow slower than the high speed air flow is the front side passage 122b. Is formed.

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

  On the other hand, the second state of the air flow of the blowout passage 122 is a state where an air flow different from the first state is formed in the blowout passage 122. For example, in the second state, the passage cross-sectional area of the rear side passage 122a is enlarged as compared to that in the first state. In short, the degree of restriction on the flow of air flowing through the rear side passage 122a is reduced. Thus, in the second state, the flow velocity of the air flow formed in the rear side passage 122a is lower than that in the first state. Then, the air flow of the rear side passage 122a is hardly along the guide wall surface 123a, and the air blown out from the blowout port 121 flows upward along the central axis CL1 of the blowout path 122.

  The air flow deflection door 14 only needs to be able to deflect the air flow velocity between the rear side passage 122a and the front side passage 122b, and it is necessary to completely separate and form the rear side passage 122a and the front side passage 122b. There is no.

  As shown in FIGS. 1 and 2, the blowout direction adjusting door 16 is provided inside the blowout unit 12 and adjusts the blowout direction of the air blown out from the blowout port 121 in the vehicle width direction DR3. In other words, the blowing direction adjustment door 16 adjusts the width direction component along the vehicle width direction DR3 among the three direction components constituting the blowing direction of the air. The three directional components include the vertical component as a first directional component along the vehicle vertical direction DR1, the longitudinal component as a second directional component along the vehicle longitudinal direction DR2, and the above as a third directional component. It is a width direction component. The blowing direction is, in detail, the blowing air flow direction at the blow-off port 121.

  For example, the blowing direction adjusting door 16 adjusts the blowing direction so that the blowing direction of air is obliquely upward as shown by the arrow ARb and the arrow ARc in FIG. 2 according to the turning angle of the blowing direction adjusting door 16 Do. That is, in FIG. 2, the blowing direction of air is represented by arrow ARb and arrow ARc.

  Specifically, a plurality of blowing direction adjusting doors 16 are provided. The plurality of blowing direction adjusting doors 16 form a louver, and are arranged side by side in the vehicle width direction DR3 with an interval therebetween. As shown in FIG. 1 and FIG. 2, the plurality of blowing direction adjusting doors 16 are all disposed downstream of the air flow deflecting door 14 in the flow direction of the blowing air of the blowing air blown out from the blowout port 121 There is. The downstream side is the upper side in the vehicle vertical direction DR1 in the present embodiment.

  The blowout direction adjustment door 16 has an air guide portion 161 and a pivot shaft 162. The air guiding portion 161 has a substantially rectangular flat plate shape whose longitudinal direction is the vehicle longitudinal direction DR2. In addition, the air guiding portion 161 is formed to extend from the pivoting shaft 162 to one side and the other side in the radial direction of the pivoting shaft 162.

  Then, the air guiding portion 161 of the blowing direction adjusting door 16 includes an upstream end 161c located on the upstream side in the air flow direction along the air guiding surface 161a indicated by the arrows ARb and ARc, and the air guiding surface 161a. And a downstream end 161d located downstream in the air flow direction. That is, the upstream end 161 c of the air guiding portion 161 is located on the opposite side to the downstream end 161 d of the air guiding portion 161.

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

  The pivot 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 to the air guiding portion 161. The fact that the pivoting shaft 162 is provided with the vehicle longitudinal direction DR2 as the axial direction does not necessarily mean that the axial direction of the pivoting shaft 162 completely coincides with the vehicle longitudinal direction DR2, but the axial direction is the vehicle longitudinal direction It also means that it is slightly inclined to DR2.

  The pivot shaft 162 is connected to, for example, an electric actuator, and is pivoted by the actuator. At the same time, the pivoting shaft 162 pivots the air guiding surface 161 a formed on the air guiding portion 161. Thus, when the air guiding surface 161a is rotated, the guiding surface angle α1 formed by the air guiding surface 161a with respect to the central axis CL1 of the blowout passage 122 is changed. Then, the blowing direction adjustment door 16 adjusts the blowing direction of the air blown out from the blowout port 121 in the vehicle width direction DR3 according to the guide surface angle α1. Since central axis CL1 of blowout passage 122 is oriented along vehicle vertical direction DR1, guide surface angle α1 formed by air guiding surface 161a with respect to central axis CL1 is such that air guiding surface 161a is in the vertical direction of the vehicle It may be reworded as the guide surface angle α1 formed with respect to DR1.

  Moreover, the blowing direction adjustment door 16 is supported at both ends. That is, as shown in FIG. 1, the pivot shaft 162 is rotatably supported relative to the blowout portion 12 on the rear side in the vehicle longitudinal direction DR2 with respect to the air guide portion 161 of the blowout direction adjustment door 16 . At the same time, the pivot shaft 162 is rotatably supported relative to the blowout portion 12 also 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 guiding portion 161 of the blowout direction adjusting door 16 has a guide side end edge 161b on the rear side in the vehicle longitudinal direction DR2, that is, on the guide wall surface 123a side. The guide side end edge 161b has a curved shape corresponding to the guide wall surface 123a.

  In detail, the guide side end edge 161b has a shape along the guide wall surface 123a when the air guiding surface 161a is upward and downward along the vehicle vertical direction DR1, and the space with respect to the guide wall surface 123a is It is provided to be open. Of course, since the air guide portion 161 must not interfere with the guide wall surface 123a, the guide side end edge 161b can be used regardless of the rotation angle of the passage inner wall surface 123 within the previously permitted allowable rotation range. There is an interval between the and the guide wall surface 123a. Since the passage inner wall surface 123 is a part of the air guiding portion 161, the allowable rotation range of the passage inner wall surface 123 is also the allowable rotation range of the air guiding portion 161. Further, the allowable rotation range of the air guiding portion 161 is narrower than 180 °, and the upstream end 161 c of the air guiding portion 161 is rotated regardless of any rotation angle within the allowable rotation range. And the position of the downstream end 161d do not reverse in the vehicle vertical direction DR1.

  In the air blowing device 10 configured as described above, the air blowing direction of the air blown out from the air outlet 121 is adjusted by the air flow 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 blowout direction adjusting door 16 is in the main flow direction (ie, the blowout air flow direction) of the blowout air blown out from the blowout port 121. It is disposed downstream of the air flow deflection door 14. Therefore, the blowout direction adjustment door 16 can be provided with a role of preventing foreign matter from entering the blowout portion 12 from the blowout port 121. Therefore, it is not necessary to arrange the member equivalent to the cover which the air blowing device described in Patent Document 1 has in the vicinity of the air outlet 121. Therefore, there is no disturbance that the blowing direction of the air adjusted by the blowing direction adjustment door 16 is corrected by the cover, and it is possible to blow out air from the blowout port 121 while maintaining the blowing direction.

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

  Further, according to the present embodiment, the air blowout direction air is controlled by the blowout direction adjusting door 16 having the role of preventing foreign matter from entering the blowout portion 12 from the blowout port 121 as described above. The member corresponding to the cover which an apparatus has can be made unnecessary. Therefore, the air blowing device 10 can be miniaturized in the axial direction of the central axis line CL1 of the blowout passage 122 as compared with the configuration having the cover. That is, in the case of FIG. 1, it is possible to miniaturize the air blowing device 10 in the vehicle vertical direction DR1. As a result, it is possible to improve the on-vehicle mountability of the air blowing device 10.

  Further, according to the present embodiment, as shown in FIG. 1 and FIG. 2, the blowing direction adjusting door 16 is an air guiding portion in which the air guiding surface 161 a along which the blowing air blown out from the blowout port 121 flows is formed. 161 and a pivot shaft 162. The pivoting shaft 162 is provided with the vehicle longitudinal direction DR2 as an axial direction, is fixed to the air guiding portion 161, and pivots the air guiding surface 161a. The blowing direction adjustment door 16 sets the blowing direction of the air blown out from the blowout port 121 in the vehicle width direction DR3 in accordance with the guide surface angle α1 formed by the air guiding surface 161a with respect to the central axis CL1 of the blowout passage 122. adjust. Therefore, it is possible to obtain the function of adjusting the blowing direction in the vehicle width direction DR3 while making the blowing direction adjusting door 16 simple.

  Further, according to the present embodiment, as shown in FIG. 1 and FIG. 2, when the air guiding surface 161 a of the guide side edge 161 b of the air guiding portion 161 is oriented along the vehicle vertical direction DR1 It has a shape along the guide wall surface 123a and is provided to be spaced from the guide wall surface 123a. Therefore, it is possible for the blowing direction adjustment door 16 to exert the effect of adjusting the blowing 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 a space therebetween. ing. Therefore, compared with the configuration in which the number of the blowing direction adjusting door 16 is one, it is easy to strongly obtain the effect of the blowing direction adjusting door 16 adjusting the blowing direction in the vehicle width direction DR3. Furthermore, it is also easy to obtain the effect of preventing the foreign matter from entering the blowout portion 12 from the blowout port 121 by the blowout direction adjustment door 16 to a large extent.

Second Embodiment
Next, a second embodiment will be described. In the present embodiment, points different from the first embodiment described above will be mainly described. In addition, 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 embodiment and later described later.

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

  Specifically, the air guiding portion 161 of the blow-out direction adjusting door 16 has an upstream end 161 c and a downstream end 161 d as in the first embodiment. However, in the present embodiment, unlike the first embodiment, the pivot shaft 162 of the outlet direction adjusting door 16 is fixed to the downstream end 161 d of the air guiding portion 161.

  That is, the air guide portion 161 of the present embodiment is formed to extend from the rotation shaft 162 only on one side of the one side and the other side in the radial direction of the rotation shaft 162. This point is different from the first embodiment. Then, the air guiding portion 161 rotates to the downstream side in the blown air flow direction in a range not exceeding the rotating shaft 162.

  For example, the air guiding portion 161 includes the upstream portion 161e shown in FIG. The upstream portion 161e is a portion of the air guiding portion 161 which occupies the upstream end 161c side in the vehicle vertical direction DR1 with respect to the turning shaft 162 when the air guiding surface 161a is upward and downward along the vehicle vertical direction DR1. It is. And the blowing direction adjustment door 16 is arrange | positioned so that the whole upstream site | part 161e may enter inside the blowing part 12, when the air guide surface 161a is turned up and down. In short, when the air guiding surface 161 a is directed upward and downward, the entire upstream portion 161 e is located in the blowout portion 12. In FIG. 4, although the air guiding surface 161 a is slightly inclined with respect to the upper side, the entire upstream portion 161 e included in the air guiding portion 161 is located in the blowout portion 12.

  According to the embodiment described above, as shown in FIG. 3, the pivot shaft 162 of the outlet direction adjusting door 16 is fixed to the downstream end 161d of the air guiding portion 161 in the air flow direction along the air guiding surface 161a. ing. Therefore, the part exposed to the vehicle interior in the blower outlet 121 among the blowing direction adjustment doors 16 can be used as the rotating shaft 162. Therefore, foreign matter can be prevented from entering the blowout portion 12 from the blowout port 121 by the pivoting shaft 162 whose width in the vehicle width direction DR3 does not change even if the blowout direction adjustment door 16 turns.

  That is, for example, the plurality of blowing direction adjusting doors 16 function as a louver for adjusting the blowing direction of air, and also function as a protection fence against the entry of foreign matter such as falling objects into the blowing portion 12. Then, it is possible to keep the gap in the vehicle width direction DR3 generated between the blowing direction adjusting doors 16 as the guard fence constant even if the blowing direction adjusting door 16 rotates.

  Further, since the pivoting shaft 162 is fixed to the downstream end 161d of the air guiding portion 161, the air guiding surface 161a of the guide side end edge 161b of the air guiding portion 161 is upward and downward along the vehicle vertical direction DR1. Approach the guide wall surface 123a most closely. Therefore, if the space between the air guide portion 161 and the guide wall surface 123a is open with the air guide surface 161a facing upward and downward, the air guide portion 161 does not interfere with the guide wall surface 123a even if it rotates. As described above, it is easy to dispose the blowing direction adjustment door 16 so as not to interfere with the guide wall surface 123a even if the air guiding portion 161 rotates, regardless of the shape of the guide side end edge 161b.

  Further, according to the present embodiment, as shown in FIG. 4, when the air guiding surface 161 a is directed upward and downward, the whole of the upstream portion 161 e included in the air guiding portion 161 is blown out. It is arranged to enter inside the part 12. Accordingly, it is possible to improve the design of the air blowing device 10 by suppressing the protrusion amount of the blowing direction adjusting door 16 protruding upward from the blowout port 121.

  In this embodiment, the same advantages as those of the first embodiment can be obtained from the configuration common to the first embodiment described above.

Third Embodiment
Next, a third embodiment will be described. In the present embodiment, points different from the first embodiment described above will be mainly described.

  As shown in FIGS. 5 and 6, in the present embodiment, unlike the first embodiment, the blowout direction adjusting door 16 is supported at one end.

  Specifically, the pivoting shaft 162 of the blowout direction adjustment door 16 blows out on the other side (that is, the front side) opposite to the one side which is the guide wall surface 123a side with respect to the air guide portion 161 in the vehicle longitudinal direction DR2. It is rotatably supported relative to the portion 12.

  Therefore, the turning shaft 162 does not protrude toward the guide wall surface 123a with respect to the air guiding 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 disposed apart from the guide wall surface 123a.

  According to the embodiment described above, as shown in FIG. 5, the pivoting axis 162 of the blowing direction adjusting door 16 is the side opposite to the air guiding portion 161 side with respect to the air guiding portion 161 in the vehicle longitudinal direction DR2 , And is rotatably supported relative to the blowout unit 12. And the blowing direction adjustment door 16 is arrange | positioned apart from the guide wall surface 123a. Therefore, the situation where the high-speed airflow flowing along the guide wall surface 123a is separated from the guide wall surface 123a due to being disturbed by the pivot shaft 162 or the like of the blowing direction adjustment door 16 due to the Coanda effect can be prevented .

  That is, it is possible to provide the blowing direction adjusting door 16 so that the blowing direction adjusting door 16 hardly affects the Coanda effect that makes the high speed air flow follow the guide wall surface 123a. Thus, the high-speed air flow can be easily directed along the guide wall surface 123a, and the air blowing device 10 can be configured to be easily bent by the Coanda effect.

  In this embodiment, the same advantages as those of the first embodiment can be obtained from the configuration common to the first embodiment described above.

  Although the present embodiment is a modification based on the first embodiment, it is also possible to combine this embodiment with the above-described second embodiment.

  Specifically, the air guiding portion 161 of the blow-out direction adjusting door 16 has an upstream end 161 c and a downstream end 161 d as in the first embodiment. However, in the present embodiment, unlike the first embodiment, the pivot shaft 162 of the outlet direction adjusting door 16 is fixed to the upstream end 161 c of the air guiding portion 161. Then, the air guiding portion 161 rotates to the upstream side in the blow air flow direction in a range not exceeding the rotating shaft 162.

  For example, the blowing direction adjustment door 16 includes the downstream portion 161 f illustrated in FIG. 8. The downstream portion 161f is a portion of the air guiding portion 161 which occupies the downstream end 161d side in the vehicle vertical direction DR1 with respect to the turning shaft 162 when the air guiding surface 161a is upward and downward along the vehicle vertical direction DR1. It is.

In short, when the air guiding surface 161a is upward and downward, the entire downstream portion 161f is located outside the blowout portion 12. In FIG. 8, although the air guiding surface 161 a is slightly inclined with respect to the upper side, the entire downstream portion 161 f included in the air guiding portion 161 is located outside the blowout portion 12.

  According to the present embodiment, since the blowout direction adjusting door 16 is configured as described above, it is difficult to cause the high speed air flow to separate from the guide wall surface 123a as in the third embodiment described above. it can.

  Further, in the configuration of the present embodiment, as shown in FIGS. 7 and 8, after the flow of the blown air is bent along the guide wall surface 123a, the blowing direction adjusting door 16 is configured to have the blowing direction of the blown air as the vehicle width. Adjust to direction DR3. Therefore, it is possible to further eliminate the influence of the outlet direction adjusting door 16 on the Coanda effect that bends the flow of the outlet air, as compared with the third embodiment.

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 guiding portion 161 has a concave shape 161g which is recessed toward the downstream end 161d. The concave shape 161g is recessed to be spaced apart from and correspond to the outer edge 14a of the turning trajectory of the airflow deflection door 14 when the air guiding surface 161a is directed upward and downward. There is. Although the air guiding surface 161a is inclined with respect to the vehicle vertical direction DR1 in FIG. 10, FIG. 9 is illustrated in a state where the air guiding surface 161a is upward and downward along the vehicle vertical direction DR1.

  According to the present embodiment, since the air guiding portion 161 of the blowing direction adjusting door 16 is configured as described above, mutual interference between the air flow 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 secure the air guide surface 161a widely.
