That is, the air outlet 15 is formed in a longitudinal shape in the left-right direction. In this embodiment, the air outlet 15 has a horizontally long rectangular shape. Furthermore, the rear end, which is the other end of the case body 12, serves as an intake port 16 that receives conditioned air from an air path such as a duct into the ventilation path 11. Conditioned air passes through the ventilation passage 11 from the intake port 16 to the outlet 15. Further, the case body 12 is formed with a contracting portion 17 that contracts toward the blow-off port 15, that is, toward the downstream side in a predetermined direction, that is, in the lateral direction, in this embodiment, in the vertical direction.

That is, the air outlet 15 includes (one and the other) air outlet guide surfaces 15a and 15b that are continuous with the guide surfaces 17a and 17b of the reduced portion 17. The blowout guide surfaces 15a and 15b form the long sides of the blowout port 15. That is, the entire long side portion of the air outlet 15 serves as the air outlet guide surfaces 15a, 15b.

In this embodiment, the general portion 18 has a rectangular tube shape with a constant cross-sectional area. Further, in this embodiment, the other end of the general portion 18, that is, the end opposite to the reduced portion 17, serves as the receiving port 16.

An air outlet 15 is formed passing through the design portion 19. The design portion 19 is formed into a plate shape extending in a direction intersecting or perpendicular to the axial direction of the case body 12. In this embodiment, the design portion 19 is continuous with the blow-off guide surfaces 15a and 15b of the blow-off port 15. The design portion 19 may be integrated with the case body 12 or may be separate.

Further, a partition wall 22 is arranged inside the case body 12, that is, in the ventilation passage 11. The partition wall 22 can also be called a fixed fin, and is formed into a plate shape that is immovable with respect to the case body 12. The partition wall 22 divides the ventilation passage 11 into at least three parts in the lateral direction, which is a predetermined direction of the case body 12, in the vertical direction in this embodiment. Furthermore, the partition wall 22 divides the ventilation passage 11 symmetrically or approximately symmetrically in a predetermined direction, ie, in the transverse direction, in this embodiment, in the vertical direction. In this embodiment, the partition wall 22 divides the ventilation path 11 into three. That is, in this embodiment, one and the other partition walls 25 and 26 are set in the partition wall 22. Branch air passages 11a, 11b, and 11c are formed between one partition wall 25 and the case body 12, between one partition wall 25 and the other partition wall 26, and between the other partition wall 26 and the case body 12, respectively. be done. The branch air passages 11a, 11b, and 11c are arranged symmetrically or approximately symmetrically with respect to the outlet 15 in a predetermined direction.

One and the other partition walls 25 and 26 are arranged in a lateral direction, which is a predetermined direction of the case body 12, and are arranged apart from each other in the vertical direction in this embodiment. That is, the one and the other partition walls 25 and 26 are arranged without shifting from each other in the axial direction of the case body 12, in other words, in the flow direction of the conditioned air passing through the ventilation passage 11. One and the other partition walls 25 and 26 are located with the central axis of the case body 12 interposed therebetween. Furthermore, the one and the other partition walls 25 and 26 are located symmetrically or approximately symmetrically in the vertical direction, which is a predetermined direction. One and the other partition walls 25 and 26 are arranged near one end of the case body 12. One and the other partition walls 25 and 26 are arranged on the downstream side of the ventilation passage 11 at a position away from the air outlet 15 on the upstream side of the ventilation passage 11. Furthermore, at least a portion of the one and the other partition walls 25 and 26 is disposed inside the reduced portion 17 within the case body 12. That is, one and the other partition walls 25 and 26 are located at a position where they partially overlap in the upstream and downstream direction of the conditioned air passing through the ventilation passage 11 with respect to the reduced portion 17, that is, in the front-rear direction that is the axial direction of the case body 12. It is located. In this embodiment, one end of the one partition wall 25 and the other partition wall 26 are arranged inside the reduced portion 17, respectively. Further, the other end portions of the one and the other partition walls 25 and 26 are respectively arranged inside the general portion 18. That is, the one and the other partition walls 25 and 26 of this embodiment extend from the reduced portion 17 to the general portion 18. Furthermore, the maximum distance of one and the other partition walls 25 and 26 in the vertical direction, which is a predetermined direction, is set to be larger than the minimum dimension of the air outlet 15 in the vertical direction, which is a predetermined direction. In other words, the branch air passage 11b has a wider portion than the air outlet 15 in the predetermined direction, that is, in the vertical direction.

Further, one end of the partition wall 22 on the outlet 15 side is inclined toward the outlet 15 along the reduced portion 17. In the present embodiment, one end of the one and the other partition walls 25 and 26 on the side of the air outlet 15 forms one and the other sloped portions 28 and 29 that are sloped along the reduced portion 17. In this embodiment, one and the other inclined portions 28 and 29 are inclined parallel to or substantially parallel to the guide surfaces 17a and 17b of the reduced portion 17. That is, the one and the other sloped parts 28 and 29 are sloped so as to approach each other toward the air outlet 15.

One of the inclined portions 28 has one (first) rectifying surface 28a on the side of the branch air passage 11a, and one (second) rectifying surface 28b on the side of the branch air passage 11b. One rectifying surface 28a is located opposite to the guide surface 17a of the reduced portion 17. Therefore, the downstream side of the branch air passage 11a is inclined toward the air outlet 15.

The other inclined portion 29 has a (first) other rectifying surface 29a on the branch air passage 11c side, and a (second) other rectifying surface 29b on the branch air passage 11b side. The other rectifying surface 29a is located opposite the guide surface 17b of the reduced portion 17. Therefore, the downstream side of the branch air passage 11c is inclined toward the air outlet 15.

As shown in FIG. 2, one of the rectifying surfaces 28a of one of the inclined portions 28 is parallel or approximately parallel to the air outlet guide surface 15b of the air outlet 15, and is not located on the same plane. . One of the rectifying surfaces 28a of one of the inclined portions 28 is located shifted toward the center of the air outlet 15 with respect to the air outlet guide surface 15b of the air outlet 15. That is, one of the rectifying surfaces 28a has its virtual extension surface located inside the air outlet 15 with respect to the air outlet guide surface 15b.

Similarly, the other rectifying surface 29a of the other inclined portion 29 is parallel or approximately parallel to the blow-off guide surface 15a of the blow-off port 15, and is not located on the same plane. The other rectifying surface 29a of the other inclined portion 29 is located shifted toward the center of the air outlet 15 with respect to the air outlet guide surface 15b of the air outlet 15. That is, the other rectifying surface 29a has its virtual extension surface located inside the air outlet 15 with respect to the air outlet guide surface 15a.

Furthermore, in the present embodiment, the distance between one end of the one and the other inclined portions 28, 29 is smaller than the minimum dimension of the air outlet 15 in the vertical direction, which is a predetermined direction.

Further, as shown in FIG. 1, an adjustment member 31 is movably disposed inside the case body 12, that is, in the ventilation passage 11. The adjustment member 31 adjusts the flow rate of the ventilation passage 11 divided by the partition wall 22 according to the operation. That is, the adjustment member 31 adjusts the flow rate of the conditioned air passing through the branch air paths 11a, 11b, and 11c according to the operation. Further, the adjustment member 31 has a function of guiding the flow path switching of the conditioned air. In this embodiment, the adjustment member 31 is a plate-shaped rotating fin that adjusts the flow rate of the conditioned air according to the rotation angle. The adjustment member 31 is configured to rotate in one and the other predetermined directions, in this embodiment, in the vertical direction, by being operated by the operating section 32 shown in FIG. In this embodiment, the operating section 32 is exposed through an opening 33 formed on the side of the air outlet 15 in the design section 19, and can be operated by the passenger. In the illustrated example, the operation unit 32 is, for example, an operation dial, but it may also be an operation lever, a knob, or the like.

At least a portion of the adjustment member 31 shown in FIG. 1 is located upstream of the ventilation passage 11 with respect to the partition wall 22. The adjustment member 31 is arranged with one end 31a facing the partition wall 22, that is, on the downstream side of the ventilation passage 11, and the other end 31b on the opposite side, that is, on the upstream side of the ventilation passage 11. Furthermore, at least the other end portion 31b of the adjustment member 31 is located upstream of the ventilation passage 11 with respect to the partition wall 22. The other end portion 31b of the adjustment member 31 is configured to come into contact with or come close to the general portion 18 when the adjustment member 31 is rotated to the maximum.

Furthermore, in this embodiment, the adjustment member 31 is located between the partition walls 22. That is, the adjustment member 31 is located at the middle or approximately the middle between the one and the other partition walls 25 and 26 in the lateral direction, which is a predetermined direction of the case body 12, in the vertical direction in this embodiment. The adjustment member 31 is arranged at a position that includes the central axis of the case body 12. One end 31a of the adjustment member 31 may be inserted into the branch air passage 11b, or may be located upstream of the branch air passage 11b.

Further, the rotation shaft 31c of the adjustment member 31 is arranged closer to the one end 31a than the intermediate position between the one end 31a on the partition wall 22 side and the other end 31b on the opposite side. In other words, the distance from the rotation shaft 31c to the other end 31b is longer than the distance from the rotation shaft 31c to the one end 31a. That is, the adjustment member 31 has an eccentric center of rotation.

Next, the operation of the first embodiment will be explained.

When the adjustment member 31 is rotated in one direction, for example, as shown by the two-dot chain line L1 in FIG. The conditioned air passing through the channel 11 has a larger flow rate in the branched air channel 11a, and is rectified along the guide surface 17a of the reduced portion 17 and one of the rectifying surfaces 28a of the partition wall 22, resulting in an airflow ( The airflow (indicated by arrow W1) becomes dominant, and the airflow (indicated by arrow W2) is rectified along between the guide surface 17b of the reduced portion 17 and the other rectifying surface 29a of the partition wall 22 and flows toward the outlet 15. The interference at the position becomes weaker. Therefore, the direction of the conditioned air blown out from the outlet 15 is biased toward the direction of the air flow of the conditioned air passing through the branched air passage 11a. That is, in this embodiment, the conditioned air is blown downward from the air outlet 15.

On the other hand, when the adjustment member 31 is rotated in the other direction, for example, as shown by the two-dot chain line L2 in FIG. The conditioned air that passes through the ventilation passage 11 from the above has a large flow rate in the branch air passage 11c, is rectified along between the guide surface 17b of the reduced part 17 and the other rectification surface 29a of the partition wall 22, and flows toward the air outlet 15. The airflow (indicated by arrow W2) becomes dominant, and the airflow (indicated by arrow W1) is rectified along between the guide surface 17a of the reduced portion 17 and one rectifying surface 28a of the partition wall 22 and flows toward the outlet 15. Interference at exit 15 becomes weaker. Therefore, the direction of the conditioned air blown out from the outlet 15 is biased toward the direction of the air flow of the conditioned air passing through the branched air passage 11c. That is, in this embodiment, the conditioned air is blown upward from the air outlet 15.

Furthermore, as shown by the solid line in FIG. 1, when the adjustment member 31 is in the neutral position in the rotation direction, the conditioned air passing through the ventilation passage 11 from the intake port 16 is directed to each branch air passage 11a, 11b, and 11c. each inflow. At this time, the conditioned air flowing into the branch air passage 11a is rectified along between the guide surface 17a of the reduced part 17 and one of the rectifying surfaces 28a of the partition wall 22, and the airflow flows toward the outlet 15 (as shown by arrow W1). Therefore, the conditioned air flowing into the branch air passage 11b is rectified along between the guide surface 17b of the reduced part 17 and the other rectifying surface 29a of the partition wall 22, and becomes an airflow (shown by arrow W2) flowing toward the outlet 15. However, since these flow rates are approximately equal, they cancel each other out at a position between the partition walls 22 on the upstream side of the air outlet 15. Furthermore, the conditioned air flowing into the branch air passage 11b heads linearly toward the outlet 15 in a state where it is narrowed down by one rectifying surface 28b and the other rectifying surface 29b of the partition wall 22. Therefore, the conditioned air (indicated by arrow W3) flowing into the branch air passage 11b is rectified along between the guide surface 17a of the reduced portion 17 and one of the rectifying surfaces 28a of the partition wall 22, and becomes an airflow flowing toward the outlet 15. The airflow is blown out from the air outlet 15 in a straight line because it is difficult to offset by the airflow that is rectified along the guide surface 17b of the reduced portion 17 and the other rectifying surface 29a of the partition wall 22 and flows toward the air outlet 15. That is, in the present embodiment, straight air is blown out from the outlet 15.

Then, the distribution of the conditioned air to the branch air passages 11a, 11b, and 11c is adjusted and changed according to the rotation angle of the adjustment member 31. By interfering with each other at the position, the direction of the conditioned air blown out from the outlet 15 is controlled.

As described above, according to the first embodiment, the case body 12 is formed with the reducing portion 17 that shrinks in a predetermined direction toward the air outlet 15, and the ventilation passage 11 inside the case body 12 is formed in at least a predetermined direction. By tilting the end of the partition wall 22 that is divided into three on the outlet 15 side toward the outlet 15 in a predetermined direction, the adjustment member 31 creates branched air passages 11a, 11b, and 11c, which are divided ventilation passages. Mutual interference at the positions of the air outlet 15 of the air-conditioned air distributed between the air conditioners is effectively controlled, and good wind direction control is possible with a simple configuration. Therefore, the mechanism can be established in a small space, and the number of mechanical parts for controlling the wind direction can be suppressed, so that it can be manufactured at low cost.

Since the end of the partition wall 22 on the side of the air outlet 15 is inclined toward the air outlet 15 along the reduced part 17 of the case body 12, the branch air paths 11a and 11c, which are air paths divided by the partition wall 22, can be formed. Since the conditioned air passing through is rectified between the reduced part 17 and the end of the partition wall 22 on the outlet 15 side (one and the other inclined parts 28, 29), the wind direction controllability can be improved.

In addition, one rectifying surface 28a of one inclined portion 28 and the other rectifying surface 29a of the other inclined portion 29 are parallel or substantially parallel to the blowing guide surfaces 15b and 15a of the blowing outlet 15, and , since the virtual extension surfaces of one rectifying surface 28a and the other rectifying surface 29a are located inside the air outlet 15 with respect to the air outlet guide surfaces 15b and 15a, the reduced portion 17 and the partition wall 22 on the air outlet 15 side are The wind rectified between the end portions (one and the other inclined portions 28, 29) is not blown onto the edge of the outlet 15, and can be discharged with little loss.

By setting the rotation axis 31c of the adjustment member 31 closer to the one end 31a than the intermediate position between the one end 31a on the partition wall 22 side and the other end 31b on the opposite side, the rotation angle of the adjustment member 31 is small. In other words, even if the angle is shallow, the flow rate to each of the branch air paths 11a, 11b, and 11c can be adjusted, and a sudden increase in ventilation resistance can be suppressed. Therefore, the pressure loss of the air-conditioned air can be suppressed, and good control of the wind direction becomes possible.

Since the adjustment member 31 is located away from the air outlet 15 on the upstream side of the ventilation passage 11, the internal structure of the air direction adjustment device 10 is difficult to see from the air outlet 15, resulting in a good appearance.

Further, since the air outlet 15 can be made thinner by the reduction part 17, the degree of freedom in designing the panel on which the wind direction adjustment device 10 is arranged can be improved.

Next, a second embodiment will be described with reference to FIG. 4. Note that the same configurations and operations as those in the first embodiment described above are given the same reference numerals, and the explanation thereof will be omitted.

In the wind direction adjusting device 10 of the present embodiment, an enlarged portion 35 is formed in the case body 12 on the side opposite to the air outlet 15 with respect to the partition wall 22, that is, on the upstream side of the ventilation path 11. That is, the case body 12 of this embodiment is constricted at the enlarged portion 35.

The enlarged portion 35 is formed to enlarge the cross-sectional area of the ventilation passage 11 from the upstream side to the downstream side. The enlarged portion 35 is located at the other end of the case body 12. In this embodiment, the enlarged part 35 is located in a continuous manner with the other end of the general part 18, which is the opposite side to the reduced part 17. Further, the enlarged portion 35 is arranged in a range overlapping with the adjustment member 31 in the upstream and downstream direction of the conditioned air passing through the ventilation passage 11, that is, in the front-rear direction that is the axial direction of the case body 12. Further, the enlarged portion 35 extends at least toward the rear side (downstream side), which is the side opposite to the air outlet 15, with respect to the rotation axis 31c of the adjustment member 31. In the present embodiment, the enlarged portion 35 is located in a range between one end 31a and the other end 31b of the adjustment member 31 in the axial direction, that is, the front-back direction of the case body 12.

Further, the enlarged portion 35 includes inclined surfaces 35a and 35b (on one side and the other side) that are inclined with respect to the axial direction of the case body 12. The inclined surfaces 35a and 35b are inclined toward the receiving port 16 and close to each other. Although the inclination angles of the inclined surfaces 35a and 35b may be set arbitrarily, in this embodiment, they are set to have the same angle in the opposite direction to the guide surfaces 17a and 17b. That is, in the present embodiment, the inclined surface 35a is parallel or approximately parallel to the guide surface 17b of the reduced portion 17, and the inclined surface 35b is parallel to or approximately parallel to the guide surface 17a of the reduced portion 17. They are parallel. In this embodiment, the inclined surfaces 35a and 35b are tapered surfaces that are inclined at a constant angle of inclination, but are not limited to this, and may be curved surfaces whose inclination angle gradually changes.

Further, in the present embodiment, the case body 12 is formed with an upstream general portion 36 that is connected to the enlarged portion 35 on the opposite side of the general portion 18 . The upstream general portion 36 is formed to be continuous with the other end of the enlarged portion 35. In this embodiment, the upstream general portion 36 has a rectangular tube shape with a constant cross-sectional area. The upstream general portion 36 is set to have a smaller dimension than the general portion 18 in the transverse direction, which is a predetermined direction, and in the present embodiment, in the vertical direction. Further, in this embodiment, the other end of the upstream general section 36, that is, the end opposite to the enlarged section 35, serves as the receiving port 16. Further, the other end portion 31b of the adjustment member 31 comes into contact with or approaches the upstream general portion 36 when the adjustment member 31 is rotated to the maximum.

Then, when the adjustment member 31 is rotated in one direction, for example, as shown by the two-dot chain line L1 in FIG. Due to the inclination of the member 31 and the inclination of the inclined surface 35a of the enlarged portion 35 along the inclination, the conditioned air is reliably rectified to the branch air path 11a.

Similarly, when the adjusting member 31 is rotated in the other direction, for example, as shown by the two-dot chain line L2 in FIG. Due to the inclination of the adjustment member 31 and the inclination of the inclined surface 35b of the enlarged portion 35 along the inclination, the conditioned air is reliably rectified to the branch air path 11c.

As described above, according to the present embodiment, by providing the case body 12 with the enlarged portion 35 that expands in a predetermined direction toward the air outlet 15 on the side opposite to the air outlet 15 with respect to the partition wall 22, the adjusting member 31 Adjustment of the flow rate is reliably performed with the aid of the enlarged portion 35, and the controllability of the wind direction can be improved.

Next, a third embodiment will be described with reference to FIG. Note that the same configurations and operations as in each of the above embodiments are designated by the same reference numerals, and the description thereof will be omitted.

The wind direction adjusting device 10 of the present embodiment is different from the wind direction adjusting device 10 of the second embodiment in that the other end of the partition wall 22 on the opposite side from the air outlet 15 is connected to the one end 31a of the adjusting member 31. It extends in a direction away from the air outlet 15, that is, on the upstream side of the ventilation passage 11. In this embodiment, the other end portions of the one and the other partition walls 25, 26 and the one end portion 31a of the adjustment member 31 are located so as to overlap in the upstream and downstream directions of the ventilation passage 11, that is, in the front-back direction. .

Further, the other end of the partition wall 22 on the side opposite to the air outlet 15 is inclined so as to contract in a predetermined direction away from the air outlet 15, that is, toward the upstream side of the ventilation passage 11. In this embodiment, the other end portions of the one and the other partition walls 25 and 26 are the one and the other rectifying inclined portions 38 and 39 that are inclined along the enlarged portion 35. In this embodiment, the one and the other rectifying inclined parts 38 and 39 are inclined parallel to or substantially parallel to the inclined surfaces 35a and 35b of the enlarged part 35. In other words, the one and the other rectifying inclined parts 38 and 39 are inclined so as to move away from the air outlet 15 and approach each other. The one and the other rectifying inclined parts 38 and 39 serve as regulating parts that regulate the rotation angle of the adjusting member 31. One and the other rectifying inclined portions 38, 39 are located close to one end 31a of the adjusting member 31 when the adjusting member 31 is rotated. The one and the other rectifying inclined parts 38 and 39 may have the function of a stopper against which one end 31a of the adjusting member 31 comes into contact when the adjusting member 31 is rotated.

One of the rectifying slope portions 38 has one (first) rectifying slope 38a on the branch air passage 11a side, and one (second) rectifying slope 38b on the branch air passage 11b side. One rectifying inclined surface 38a is located opposite to the inclined surface 35a of the enlarged portion 35.

The other rectifying slope portion 39 has a (first) other rectifying slope 39a on the branch air passage 11c side, and a (second) other rectifying slope 39b on the branch air passage 11b side. The other rectifying inclined surface 39a is located opposite to the inclined surface 35b of the enlarged portion 35.

Then, when the adjustment member 31 is rotated in one direction, for example, as shown by the two-dot chain line L1 in FIG. Due to the inclination of the member 31 and the inclination of one of the rectifying slopes 38a of one of the rectifying slopes 38 and the slope 35a of the enlarged part 35 along the slope, the conditioned air is reliably rectified to the branch air path 11a. .

Similarly, when the adjustment member 31 is rotated in the other direction, for example, as shown by the two-dot chain line L2 in FIG. Due to the inclination of the adjustment member 31 and the inclinations of the other rectifying inclined surface 39a of the other rectifying inclined part 39 and the inclined surface 35b of the enlarged part 35 along the inclination, the conditioned air is reliably rectified to the branch air passage 11c. Ru.

As described above, according to the present embodiment, by reducing the other end of the partition wall 22 in a predetermined direction toward the direction away from the air outlet 15, the flow rate can be adjusted by the adjusting member 31 together with the enlarged portion 35. This is reliably performed with the aid of the other end portions of the partition wall 22 (one and the other rectifying slope portions 38, 39), and the wind direction controllability can be further improved.

In addition, in this case, even if the rotation angle of the adjustment member 31 is small, it is possible to set the distribution of the flow rate of the conditioned air to the branch air paths 11a, 11b, and 11c, so the adjustment member 31 can be made smaller. It becomes possible to do so.

In the first embodiment described above, the other end of the partition wall 22 on the side opposite to the air outlet 15 is placed in the direction away from the air outlet 15, that is, in the direction away from the air outlet 15, with respect to one end 31a of the adjustment member 31. It may be formed by extending toward the upstream side.

Furthermore, in each of the above embodiments, as in the fourth embodiment shown in FIG. May be prevented.

Furthermore, in each of the embodiments described above, the wind direction adjustment device 10 can also be applied to a passenger in a rear seat provided, for example, at the rear end of a console box.
