Description

  The present invention relates to a wind direction adjuster provided in, for example, a duct through which conditioned air flows.

Generally, a vehicle interior has a duct for guiding conditioned air generated by an air conditioner to a desired location, and a wind direction adjuster is provided at the downstream end of the duct to adjust the blowing direction of the conditioned air. (For example, see Patent Documents 1 to 3). This type of wind direction adjuster includes a plurality of vertical fins and horizontal fins, a link that connects the vertical fins, and a link that connects the horizontal fins. The vertical fins are arranged at intervals in the horizontal direction and are supported on the wall surface of the duct by a rotating shaft extending in the vertical direction. The horizontal fins are arranged at intervals in the vertical direction, and are supported on the duct wall surface by a rotating shaft extending in the horizontal direction. By rotating these fins around the rotation axis, the air blowing direction can be adjusted.

  However, when the fins provided in the air passage are rotated to adjust the blowing direction of the air as in Patent Documents 1 to 3, if the turning angle of the fins is increased in order to greatly change the blowing direction. Since the fins are greatly inclined with respect to the center line of the air passage and the air passage is closed by the fins, the resistance during ventilation increases and a sufficient air volume cannot be obtained.

  The present invention has been made in view of such points, and an object of the present invention is to make it possible to suppress a decrease in the air volume even when the fins are largely rotated.

  To achieve the above object, according to the first aspect of the present invention, a plurality of blowing direction adjusting fins arranged in the air passage so as to be arranged at intervals in a direction intersecting the air flow direction, A pivot shaft that rotatably supports the fin with respect to the wall surface of the air passage; and a link that connects the plurality of fins to each other. A wind direction adjuster configured to adjust the air blowing direction by rotating around, wherein the position of the rotation shaft bends in a direction in which the air flow is inclined with respect to the center line of the air passage. Thus, when the said fin is rotated, it is set as the structure set so that the space | interval of an adjacent fin may become wide on the mainstream side of the air which flows through the inside of the said air path.

  According to a second invention, in the first invention, the fin is located closer to the inner periphery of the air flow than the rotation shaft of the fin located on the outer periphery of the air flow that bends in a direction inclined with respect to the center line of the air passage. The rotating shaft of the fin located is configured to be positioned on the upstream side of the air flow.

  In the third invention, in the first or second invention, the dimension in the air flow direction of the outer end fin located at the outer end part in the fin arrangement direction is larger than the dimension in the same direction of the fin adjacent to the outer end fin. The configuration is set short.

  According to the first invention, when the fins are rotated so that the air flow bends in a direction inclined with respect to the center line of the air passage, the interval between the adjacent fins is on the main flow side of the air flowing in the air passage. Become wider. Thereby, since it becomes easy for air to flow on the mainstream side where the flow rate of air is relatively increased in the air passage, it is possible to suppress a decrease in air volume even when the fins are largely rotated.

  According to the second invention, by positioning the rotation axis of the fin located on the outer peripheral side of the air flow on the upstream side in the air flow direction from the rotation axis of the fin positioned on the inner peripheral side of the air flow, Both rotating shafts come away in the air flow direction. Thereby, when rotating a fin, the space | interval of a fin can be extended on the outer peripheral side of an air flow. And the main flow of the air that flows so as to bend in a direction inclined with respect to the center line of the air passage is located on the outer peripheral side of the air flow, and the simple structure that the rotating shaft is separated in the air flow direction as described above. Thus, the interval between adjacent fins can be widened on the main flow side of the air flowing in the air passage, and thus the structure can be simplified.

  According to the third invention, since the dimension of the outer end fin in the air flow direction is shorter than the dimension of the fin adjacent to the outer end fin in the same direction, the outer end fin is rotated when the outer end fin is rotated. The end of the fin in the air flow direction is less likely to contact the wall surface of the air passage, and the rotation angle can be increased.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that the following description of the preferred embodiment is merely illustrative in nature, and is not intended to limit the present invention, its application, or its use.

Embodiment 1 of the Invention
FIG. 1 shows a right side portion of a vehicle instrument panel P in which a wind direction adjuster 1 according to Embodiment 1 of the present invention is assembled. Inside the instrument panel P, an air conditioner (not shown) and a vent duct D (shown in FIG. 2) into which conditioned air generated by the air conditioner is introduced are accommodated. Further, the vent duct D is branched into three in the middle, and extends to the left and right sides of the instrument panel P and to the center.

Are arranged respectively. For example, the downstream side of the vent duct D extends upward with respect to the horizontal plane toward the rear side of the vehicle in an inclined range of 30 ° to 45 °. The reason why the downstream side of the vent duct D is inclined in this way is to avoid various parts arranged in the instrument panel P. In this embodiment, the inclination angle on the downstream side of the vent duct D is set to 45 °, but the present invention is not limited to this. In the description of this embodiment, for convenience of explanation, the front side of the vehicle is simply referred to as “front”, the rear side of the vehicle is simply referred to as “rear”, the left side of the vehicle is simply referred to as “left”, and the right side of the vehicle is referred to.

The cylindrical member 5 extends in the front-rear direction, and the center line extends with an inclination of 45 ° with respect to the horizontal plane so that the rear side is positioned higher than the front side. Since the inclination angle between the center line of the cylindrical member 5 and the center line on the downstream side of the vent duct D is the same, the wind direction adjuster 1 can be easily assembled to the vent duct D.

  The cross-sectional shape in the direction perpendicular to the center line of the cylindrical member 5 is a rectangular shape that is long in the left-right direction. Further, the rear end portion of the tubular member 5 is fitted in the opening A of the instrument panel P.

Further, the front end portion of the cylindrical member 5 is inserted into the downstream end portion of the vent duct D. A sealing material B is provided between the front end portion of the tubular member 5 and the downstream end portion of the vent duct D.

  The vertically movable louver 10 includes first to fifth horizontal fins 11 to 15 extending in the left-right direction, rotation shafts 11 a to 15 a and connection shafts 11 b to 15 b provided on the horizontal fins 11 to 15, and horizontal fins 11 to 11. ..

That is, the first to fifth horizontal fins 11 to 15 are arranged in the air passage S at intervals in a direction (crossing direction) perpendicular to the direction along the center line of the cylindrical member 5 (air flow direction). It is arranged.

  The intervals between the first to fifth horizontal fins 11 to 15 are set equal. Moreover, the space | interval of the 1st horizontal fin 11 and the upper wall of the cylinder member 5 is the state of the 1st-5th horizontal fins 11-15 of the state which does not rotate (rotation angle 0 degree) shown by the continuous line in FIG. The interval is set to be the same as the interval, and the interval between the fifth horizontal fin 15 and the lower wall of the cylindrical member 5 is also set to be the same as the interval between the first to fifth horizontal fins 11 to 15 in a non-rotating state. ing. The state in which the first to fifth horizontal fins 11 to 15 are not rotating is a state in which the first to fifth horizontal fins 11 to 15 extend along the center line of the cylindrical member 5.

  Moreover, each of the thickness of the 1st-5th horizontal fins 11-15, the dimension of the left-right direction, and the dimension of an air flow direction is set the same, and the 1st-5th horizontal fins 11-15 are the same. It is. Further, the downstream ends of the first to fifth horizontal fins 11 to 15 in the air flow direction are located on the same plane orthogonal to the center line of the cylindrical member 5. As shown in FIG. 1, an operation knob 17 is provided at the center in the left-right direction of the third horizontal fin 13.

  As shown in FIG. 2, the rotation shaft 11 a of the first horizontal fin 11 is provided at both left and right ends of the first horizontal fin 11, and the right rotation shaft 11 a protrudes to the right, A rotating shaft (not shown) protrudes leftward. The right and left rotation shafts 11a are rotatably inserted into bearing holes (not shown) opened in the right and left walls of the cylinder member 5, respectively. Moreover, the rotating shafts 12a-15a of the 2nd-5th horizontal fins 12-15 are similarly provided in the right-and-left both ends of the 2nd-5th horizontal fins 12-15, respectively, and are the bearings of the cylinder member 5, respectively. It is inserted so as to be rotatable with respect to the hole.

  The rotation shaft 11 a of the first horizontal fin 11 is positioned at the center of the first horizontal fin 11 in the air flow direction. The rotation shaft 12a of the second horizontal fin 12 is located upstream of the central portion of the second horizontal fin 12 in the air flow direction. The rotation shaft 13a of the third horizontal fin 13 is located upstream of the rotation shaft 12a of the second horizontal fin 12 in the air flow direction. The rotation shaft 14 a of the fourth horizontal fin 14 is located downstream of the rotation shaft 13 a of the third horizontal fin 13 in the air flow direction. The rotation shaft 15 a of the fifth horizontal fin 15 is located at the center in the air flow direction, like the rotation shaft 11 a of the first horizontal fin 11.

  The connection shafts 11b to 15b of the first to fifth horizontal fins 11 to 15 are provided on the upstream side in the air flow direction from the rotation shafts 11a to 15a of the first to fifth horizontal fins 11 to 15, respectively. The connecting shafts 11b to 15b are positioned so that the line connecting the connecting shafts 11b to 15b is parallel to the line connecting the rotating shafts 11a to 15a.

  The links 16, 16,... Are respectively connected to the connecting shaft 11 b of the first horizontal fin 11 and the connecting shaft 12 b of the second horizontal fin 12, and between the connecting shaft 12 b of the second horizontal fin 12 and the third horizontal fin 13. Connected to the connecting shaft 13b, connected to the connecting shaft 13b of the third horizontal fin 13 and the connecting shaft 14b of the fourth horizontal fin 14, and connected to the connecting shaft 14b of the fourth horizontal fin 14 and the fifth horizontal fin 15 15b. Further, the links 16, 16,... Rotate around the connecting shafts 11b to 15b. Therefore, when any one of the first to fifth horizontal fins 11 to 15 is rotated. The other horizontal fins are interlocked to rotate in the same direction (shown by phantom lines in FIG. 2). At this time, since the positions of the connecting shafts 11b to 15b are set as described above, the rotation angles of the first to fifth horizontal fins 11 to 15 are the same.

  Moreover, the rotation range of the horizontal fins 11-15 can be arbitrarily set by a stopper (not shown). In the first embodiment, the first horizontal fin 11 and the fifth horizontal fin 15 are set so as to be separated from the wall surface of the air passage S by a predetermined distance.

  The left and right movable louvers 20 include first to third vertical fins 21 to 23 (shown in FIG. 1) extending in the vertical direction, and rotating shafts 21a provided on the vertical fins 21 to 23 (of the first vertical fin 21). Only), a connecting shaft (not shown), and a link (not shown) for connecting the vertical fins 21 to 23 to each other, and upstream of the vertically movable louver 10 in the air passage S in the air flow direction. It is arranged. The first to third vertical fins 21 to 23 are arranged at equal intervals in the left-right direction. The rotation shaft 21a is provided at both upper and lower ends of the first to third vertical fins 21 to 23. The rotation shafts 21a are inserted so as to be rotatable with respect to bearing holes (not shown) opened in the upper wall and the lower wall of the cylindrical member 5, respectively. Further, like the vertically movable louver 10, the connecting shaft is provided on the upstream side of the air flow from the rotating shaft 21a of the first to third vertical fins 21 to 23. The link is connected to the connecting shaft in the same manner as the link 16 of the vertically movable louver 10.

  Since the operation knob 17 is well known in the art, detailed description thereof is omitted, but the operation knob 17 is engaged with the second vertical fin 22 of the left and right movable louver 20. The left and right movable louvers 20 can also be moved by the operation knob 17.

  In addition, the code | symbol 40 of FIG. 1 is a dial for operating the door (not shown) which opens and closes the air path S. FIG. Moreover, the code | symbol 41 of the figure is a demister grill.

  Next, the case where the wind direction adjuster 1 comprised as mentioned above is used is demonstrated. In the state where the first to fifth horizontal fins 11 to 15 of the vertically movable louver 10 are not rotated, the air passage S and the horizontal fins 11 to 15 extend obliquely upward, so that conditioned air blows obliquely upward. become. Since the conditioned air blown out from the vent duct D is generally preferably supplied toward the occupant's chest, the lateral fins 11 to 15 need to be largely rotated downward.

  That is, from the state where the first to fifth horizontal fins 11 to 15 of the vertically movable louver 10 are not rotated (shown by solid lines in FIG. 2), the operation knob 17 is operated to rotate the horizontal fins 11 to 15 downward. When moved (indicated by phantom lines in the figure), the conditioned air bends in a direction inclined with respect to the center line of the air passage S. When the air flow is bent, the main flow flows through the upper portion of the air passage S that is the outer peripheral side of the air flow.

  On the other hand, when the first to fifth horizontal fins 11 to 15 are rotated downward, the rotation shaft 12a of the second horizontal fin 12 is more upstream of the air flow than the rotation shaft 11a of the first horizontal fin 11. Therefore, the distance L1 after the rotation between the first horizontal fin 11 and the second horizontal fin 12 is equal to the distance L3 after the rotation between the third horizontal fin 13 and the fourth horizontal fin 14 and the fourth horizontal fin. It becomes wider than the interval L4 after the rotation between the fin 14 and the fifth lateral fin 15. In addition, since the rotation shaft 13a of the third horizontal fin 13 is located upstream of the rotation shaft 12a of the second horizontal fin 12, the rotation between the second horizontal fin 12 and the third horizontal fin 13 is effective. The distance L2 after the movement is also wider than L3 and L4. On the other hand, the distance L3 after the rotation between the third horizontal fin 13 and the fourth horizontal fin 14 and the distance L4 after the rotation between the fourth horizontal fin 14 and the fifth horizontal fin 15 are the distance before the rotation, respectively. Narrower than.

  Thus, the space | interval L1, L2 after rotation of the 1st-3rd horizontal fins 11-13 located in the upper part of the air path S is ensured widely, and the 1st-5th horizontal fins 11-15 are ensured. Even when the rotation angle is increased, the air easily flows on the main flow side where the air flow rate is relatively increased in the air passage S, and thus the reduction in the air volume is suppressed. Although L3 and L4 become narrower, this region has almost no influence because it is out of the main flow of air.

  Further, when the operation knob 17 is operated to rotate the first to third vertical fins 21 to 23 of the left and right movable louver 20, the blowing direction can be adjusted to the left and right.

  As described above, according to the wind direction adjuster 1 according to the first embodiment, the first to fifth horizontal fins 11 to 15 are rotated so that the air flow bends in a direction inclined with respect to the center line of the air passage S. When moved, the distances L1 and L2 between the first to third horizontal fins 11 to 13 located on the main air flow side can be secured widely. As a result, air easily flows on the main flow side where the air flow rate is relatively large in the air passage S, so that the air volume is reduced even when the first to fifth horizontal fins 11 to 15 are largely rotated. Can be suppressed.

<< Embodiment 2 of the Invention >>
FIG. 3 is a cross-sectional view of the wind direction adjuster 1 according to the second embodiment of the present invention. The wind direction adjuster 1 of the second embodiment is the same as that of the first embodiment except that the positions of the rotating shafts 11a to 15a and the dimensions of the horizontal fins 11 to 15 in the air flow direction are different. Therefore, the same parts as those in the first embodiment are denoted by the same reference numerals, description thereof will be omitted, and different parts will be described in detail.

  That is, in the second embodiment, of the first to fifth horizontal fins 11 to 15 of the vertically movable louver 10, the first horizontal fin 11 and the fifth horizontal fin 15 (outer end fin) located at the outer end in the arrangement direction. The dimension of the air flow direction is set shorter than the dimension of the second horizontal fin 12 and the fourth horizontal fin 14 in the same direction. Moreover, the dimension of the air flow direction of the 2nd-4th horizontal fins 12-14 is set the same. The air flow downstream ends of the first to fifth horizontal fins 11 to 15 are located on the same plane orthogonal to the center line of the cylindrical member 5.

  The rotation shaft 11 a of the first horizontal fin 11 is positioned near the downstream end of the first horizontal fin 11 in the air flow direction. The rotation shaft 12 a of the second horizontal fin 12 is positioned downstream of the central portion of the second horizontal fin 12 in the air flow direction and upstream of the rotation shaft 11 a of the first horizontal fin 11. The rotation shaft 13 a of the third horizontal fin 13 is positioned at the center of the third horizontal fin 13 in the air flow direction. The rotation shaft 14a of the fourth horizontal fin 14 is positioned upstream of the central portion of the fourth horizontal fin 14 in the air flow direction. The rotation shaft 15 a of the fifth horizontal fin 15 is positioned near the upstream end of the fifth fin 15 in the air flow direction and on the downstream side of the rotation shaft 14 a of the fourth horizontal fin 14.

  Next, the case where the wind direction adjuster 1 comprised as mentioned above is used is demonstrated. From the state where the horizontal fins 11 to 15 of the vertically movable louver 10 are oriented so as to extend in parallel with the center line of the air passage S, when the operation knob 17 is operated to rotate the horizontal fins 11 to 15 downward, Since the pivot shaft 12a of the two horizontal fins 12 is located upstream of the pivot shaft 11a of the first horizontal fin 11, the first horizontal fin 11 and the second horizontal fin 12 are rotated. The interval L1 becomes wider than L4. In addition, since the rotation shaft 13a of the third horizontal fin 13 is located upstream of the rotation shaft 12a of the second horizontal fin 12, the rotation between the second horizontal fin 12 and the third horizontal fin 13 is effective. The distance L2 after the movement is also larger than L4. Similarly, the distance L3 after the rotation of the third horizontal fin 13 and the fourth horizontal fin 14 is also wider than L4. The interval L4 after the rotation of the fourth horizontal fin 14 and the fifth horizontal fin 15 is narrower than the interval before the rotation.

  Thus, the space | interval L1, L2, L3 of the 1st-3rd horizontal fins 11-14 located in the upper part of the air path S is ensured widely, and the rotation of the 1st-5th horizontal fins 11-15 is ensured. Even when the moving angle is increased, the air easily flows on the main flow side where the air flow rate is relatively increased in the air passage S, and the reduction of the air volume is suppressed.

  Moreover, since the dimension of the air flow direction of the 1st horizontal fin 11 and the 5th horizontal fin 15 is set shorter than the other horizontal fins 12 and 14, these 1st-5th horizontal fins 11-15 are rotated. When it is made, the edge part of the air flow direction of the 1st and 5th horizontal fins 11 and 15 becomes difficult to contact the wall surface of the air path S. FIG.

  As described above, according to the wind direction adjuster 1 according to the second embodiment, air can easily flow on the mainstream side where the flow rate of air is relatively increased in the air passage S, as in the first embodiment. Therefore, also when the 1st-5th horizontal fins 11-15 are rotated largely, the fall of an airflow can be suppressed.

  Moreover, since the dimension of the air flow direction of the 1st horizontal fin 11 and the 5th horizontal fin 15 was set short, the rotation angle of the 1st-5th horizontal fins 11-15 can be enlarged.

  In the first and second embodiments, the number of horizontal fins is five. However, the number is not limited to this, and may be four or more.

  Moreover, although the said Embodiment 1, 2 demonstrated the case where this invention was applied to the up-and-down movable louver 10, this invention can also be applied to the left-right movable louver 20. FIG. In this case, the number of vertical fins of the left and right movable louvers 20 is preferably four or more. In addition, the present invention can be applied to a wind direction adjuster in which the vertically movable louver 10 is omitted, or can be applied to a wind direction adjuster in which the left and right movable louver 20 is omitted.

  Moreover, the dimension of the air flow direction of the 1st-5th fins 11-15 and the 1st-3rd vertical fins 21-23 can be set arbitrarily.

  Moreover, the wind direction regulator which concerns on this invention can also be provided in the blowing part of the duct installed in a residence or an office besides a vehicle.

  As described above, the wind direction adjuster according to the present invention is suitable for a duct provided in a vehicle, for example.

It is a front view of the vehicle right side part of the instrument panel provided with the wind direction regulator which concerns on Embodiment 1. FIG. It is sectional drawing in the II-II line of FIG. FIG. 3 is a view corresponding to FIG. 2 according to the second embodiment.
