  2. Description of the Related Art Conventionally, as this type of vehicle air blowing device, an air blowing device having an elongated air outlet extending in the vehicle width direction and having a plurality of vertical fins arranged in the longitudinal direction of the air outlet is known.

Japanese Patent Publication No. 05-008346

  However, in the conventional vehicle air blowing device, the vertical fin is formed relatively long from the vicinity of the air outlet to the inside of the duct that flows the air flow in the lateral direction from the vicinity of the air outlet. Because it is provided in a manner that shields the flow, the side of the vertical fin facing the air inflow direction (the surface opposite to the air inflow side) has a negative pressure, It is easy to generate turbulent flow near the outlet. When a turbulent flow is generated in the vicinity of the air outlet, an irregular vortex is formed, so that the airflow resistance is increased and the smooth air blowing from the air outlet is hindered. Furthermore, such irregular vortices affect the air flow blown out from the air outlet, resulting in poor stability of the conditioned air blowing direction.

  The technology of the present disclosure has been made in view of such a point, and an object of the technology is to improve the stability of the blowing direction of the conditioned air while realizing smooth air blowing from the air outlet. is there.

  In order to achieve the above object, in the technology of the present disclosure, the fin shape is devised so that the generation of turbulent flow near the fin is suppressed.

  Specifically, the technology of the present disclosure is directed to a vehicle air blowing device. The vehicle air blowing device includes a duct portion through which air blown from an air conditioner circulates, and a duct portion toward a second direction perpendicular or substantially perpendicular to a first direction in which air circulates in the duct portion. And an air blowing part formed with a long and narrow air outlet extending at the tip in the first direction. Here, “substantially right angle” means to include a range inclined about 10 degrees with respect to a direction perpendicular to the first direction. The air blowing part has a pair of opposed walls facing each other in a third direction orthogonal to the first direction and the second direction, and the pair of opposed walls approach each other from the duct part side toward the outlet. It has a tapered shape.

  Between the pair of opposing walls, a plurality of fins that adjust the direction of the conditioned air blown from the air outlet in the first direction are provided at intervals along the first direction. The fin is formed along the inner surface of the facing wall facing the air blowing portion, and straddles the outlet in the third direction. And in the edge of the back side located in the duct part side among fins, the part corresponding to a blower outlet in the middle in the 3rd direction is projection of an air blowing part rather than the part of the both ends in the 3rd direction. Located on the side, a space is formed on the duct portion side in the air blowing portion.

  According to said structure, since a pair of opposing walls made the air blowing part the taper shape which approaches toward a blower outlet from a duct part side, an air conditioning wind is efficiently induced | guided | derived to a blower outlet. Furthermore, the fin that adjusts the direction of the conditioned air blown out from the outlet in the longitudinal direction is relatively long in the depth direction at both ends in the direction in which the pair of opposing walls face (third direction). The direction of airflow can be changed by fins at locations along each facing wall.

  And since the fin is relatively short in the depth direction in the middle in the direction (third direction) where the pair of opposing walls face each other, the portion that shields the airflow flowing in the duct portion with the fin is reduced, And it can suppress that a turbulent flow generate | occur | produces beside a fin on the back side of an outlet. Thereby, since the ventilation resistance in the air blowing part resulting from the vortex | eddy by the said turbulent flow is reduced, smooth ventilation from a blower outlet is realizable. In addition, since the influence of the turbulent flow on the air flow blown out from the air outlet is reduced, the stability in the blowing direction of the conditioned air can be improved.

  In the air blowing device according to the technique of the present disclosure, it is preferable that the end edge on the back side of the fin is recessed in an arcuate shape on the protruding side of the air blowing portion.

  According to the above configuration, the fins are provided relatively short in the depth direction at locations where the air flow along the opposite wall can be efficiently changed, so that the air flow flowing in the duct portion is not shielded as much as possible. Thus, the airflow resistance at the air blowing portion can be suppressed as much as possible. And since the said fin was provided shortest in the back side of a blower outlet, generation | occurrence | production of the turbulent flow beside a fin is fully prevented, and the stability of the blowing direction of the conditioned air from a blower outlet is suitable. The air-conditioning air blowing direction can be more reliably directed to a desired direction.

  The duct part has a back wall corresponding to the back side of the air blowing part. The rear wall approaches the air blowing portion side from the upstream side to the downstream side in the first direction in which air flows, and is inclined with respect to the first direction and the second direction. preferable.

  According to the above configuration, the rear wall of the air blowing part is provided in an inclined posture that approaches the air blowing part as it moves away from the air inflow side, and the cross-sectional area of the duct part is directed from the upstream side to the downstream side of the air flow in the longitudinal direction. Therefore, the ventilation resistance at the duct portion is increased according to the cross-sectional area. Thereby, the air which distribute | circulates to a duct part can be distributed without biasing along the longitudinal direction to a blower outlet. Accordingly, the conditioned air can be uniformly blown out from the outlet in the longitudinal direction.

  According to the vehicle air blowing device according to the technology of the present disclosure, it is possible to improve the stability of the blowing direction of the conditioned air while realizing smooth air blowing from the air outlet.

Each bracket piece 37 is provided with a number of engagement pieces 39 corresponding to the locking claws 29 so as to protrude rearward from the bracket piece 37. A locking hole 41 is formed in the engaging piece 39. The louver case 31 is attached to the duct member 7 so as to cover the outflow port 27 by hooking the engaging pieces 39 on the upper and lower sides to the locking claws 29.

  A slender outlet 43 extending in the vehicle width direction (left-right direction) is formed at the tip of the louver case 31 in the protruding direction. The air outlet 43 is connected to and integrated with the air outlet 103. The shape of the blower outlet 43 in this embodiment is formed in the elongate rectangular shape. The louver case 31 has a tapered shape in which the pair of opposing walls 33 approach each other as it goes from the duct member 7 toward the air outlet 43.

  Both side walls 35 of the louver case 31 are formed in a substantially trapezoidal shape. One side wall 35 is formed with a rectangular attachment hole 47 for attaching a resin bush 45. The bush 45 is attached to the side wall 35 of the louver case 31 by press-fitting a rectangular insertion portion 49 into the attachment hole 47. A shaft support hole 51 is formed in the central portion of the bush 45. The other side wall 35 is formed with an insertion hole (not shown) through which the shaft support portion 55 of the angle adjustment gear 53 is inserted.

  The louver case 31 is provided with a plurality of vertical fins 57 that adjust the direction of the conditioned air blown from the outlet 43 in the left-right direction, and horizontal fins 59 that adjust the direction of the conditioned air blown from the outlet 43 in the vertical direction. ing. The plurality of vertical fins 57 and horizontal fins 59 are arranged so as to overlap in the vertical direction when viewed from the width direction of the air outlet 43. According to such an arrangement, a space occupied by both the fins 57 and 59 can be reduced as compared with the case where the plurality of vertical fins 57 and the horizontal fins 59 are shifted in the depth direction.

  The plurality of vertical fins 57 are formed integrally with the louver case 31 and are arranged at intervals in the left-right direction. The vertical fins 57 extend along the inner surface of the facing wall 33 facing the louver case 31, are formed integrally with the facing wall 33, and straddle the outlet 43 in the vertical direction. The vertical fins 57 are formed in a substantially boomerang shape, partition the louver case 31 in the longitudinal direction, and also play a role of increasing the rigidity of the louver case 31.

  As shown in FIGS. 2 and 3, the rear edge 61 of the vertical fin 57 located on the duct member 7 side is recessed in a shape curved in an arcuate shape toward the rear, which is the protruding side of the louver case 31. Yes. In the edge 61 on the back side of the vertical fin 57, the portion corresponding to the outlet 43 in the middle in the up-down direction is located behind the portion on both ends in the up-down direction, and the duct member in the louver case 31. A space 63 is formed on the 7 side. An accommodation recess 65 that is recessed toward the duct member 7 is formed in a rear portion of the vertical fin 57 that corresponds to the air outlet 43. The upper and lower end edges of the opening facing the rear of the housing recess 65 are continuous with the air outlet 43.

  The lateral fin 59 is configured by a movable fin member 67 that is separate from the louver case 31. The movable fin member 67 is accommodated lying in the accommodating recess 65 of each vertical fin 57. The movable fin member 67 has a laterally long lateral fin 59 extending over the entire length of the air outlet 43 and a pair of shaft portions 69 protruding from both end portions in the longitudinal direction of the lateral fin 59. The horizontal fin 59 has a semicircular front and a tapering cross section at the rear, and is provided with the tip directed toward or from the air outlet 43.

  One shaft portion 69 is inserted into the shaft support hole 51 of the bush 45 and is rotatably supported by the louver case 31 via the bush 45. The other shaft portion 69 is press-fitted into an insertion hole formed in the shaft support portion 55 of the angle adjustment gear 53, and is rotatably supported by the louver case 31 via the shaft support portion 55. The angle adjustment gear 53 is connected to a drive gear attached to an output shaft of a motor (not shown). The movable fin member 67 is rotated by the operation of the motor.

  In the air blowing device 1 having the above-described configuration, the air blown from the air conditioner flows into the duct member 7 along the longitudinal direction from the right side via the relay duct. Then, the air that has flowed into the duct member 7 is redirected by the plurality of vertical fins 57 and blown out from the air outlet 43 to the passenger seat side through the air outlet 103. At this time, the louver case 31 has a tapered shape in which the pair of opposing walls 33 approach from the duct member 7 side toward the air outlet 43, so that the conditioned air is efficiently guided to the air outlet 43.

  Moreover, in this embodiment, since the cross-sectional area of the duct member 7 is gradually narrowed from the upstream side to the downstream side of the air flow along the longitudinal direction, the airflow resistance in the duct member 7 becomes the cross-sectional area. Increased accordingly. Thereby, since the air which distribute | circulates to the duct member 7 is distributed without being biased along the longitudinal direction to the blower outlet 43, conditioned air is blown out uniformly from the blower outlet 43 in the longitudinal direction.

  The direction in which the conditioned air is blown out from the air outlet 43 is changed in the vertical direction by the rotation operation of the movable fin member 67. When the horizontal fin 59 of the movable fin member 67 is in a horizontal state, that is, in a state in which the front end of the horizontal fin 59 is directed rearward, the conditioned air is blown straight out from the air outlet 43 toward the passenger in the passenger seat. When the horizontal fin 59 of the movable fin member 67 is rotated downward from the horizontal state, that is, when the front end of the horizontal fin 59 is directed downward, the conditioned air is directed from the air outlet 43 to the lower side of the passenger seat. And blown out. On the contrary, when the horizontal fin 59 of the movable fin member 67 is rotated upward from the horizontal state, that is, when the front end of the horizontal fin 59 is directed upward, the conditioned air is blown from the air outlet 43 to the upper side of the passenger seat. It is blown out toward.

-Effect of the embodiment-
According to the vehicle air blowing device 1 according to this embodiment, it is possible to improve the stability in the blowing direction of the conditioned air while realizing smooth air blowing from the air outlet 43. This will be described below with reference to FIGS. In the following description, for the sake of convenience, in the air blowing device 201 of the comparative example, the same reference numerals are assigned to the components corresponding to the air blowing device 1 of this embodiment.

  FIG. 6 is a perspective view of an air blowing device 201 according to a comparative example. FIG. 7 is a longitudinal sectional view of an air blowing device 201 according to a comparative example. FIG. 8 is a cross-sectional view showing the flow of air in the air blowing device 201 according to the comparative example. FIG. 9 is a longitudinal sectional view showing the air flow in the air blowing device 201 according to the comparative example. FIG. 10 is a cross-sectional view showing the flow of air in the air blowing device 1 according to this embodiment. FIG. 11 is a longitudinal sectional view showing the flow of air in the air blowing device 1 according to this embodiment.

  As shown in FIGS. 6 and 7, the air blowing device 201 of the comparative example has a substantially trapezoidal shape with the vertical fins 57 corresponding to the side walls 35 of the louver case 31, and is provided in the air blowing device 1 of the above embodiment. It is formed longer than the vertical fins 57 in the depth direction. The rear edge 61 of the vertical fin 57 is formed in a straight line extending straight in the vertical direction.

  In such an air blowing device 201, since the vertical fins 57 are provided in such a manner as to shield the air flow flowing through the duct member 7, the side of the vertical fins 57 facing the air inflow direction is a negative pressure. As a result, it is easy to generate turbulent flow near the outlet 43 as shown in FIGS. When a turbulent flow is generated in the vicinity of the air outlet 43, an irregular vortex is formed, so that the airflow resistance is increased and the smooth air blowing from the air outlet 43 is hindered. Furthermore, since such irregular vortices affect the air flow blown out from the outlet 43, the stability of the blowing direction of the conditioned air is poor, and the conditioned air is blown out toward the right side as shown in FIG. The direction of the air-conditioning wind fluctuates as it is blown out straight toward the front.

  On the other hand, according to the air blowing device 1 according to this embodiment, the portion corresponding to the air outlet 43 in the middle in the vertical direction of the vertical fins 57 is relatively shorter in the depth direction than both ends thereof. Therefore, the airflow flowing through the duct member 7 is prevented from being shielded as much as possible, and the occurrence of turbulent flow near the vertical fins 57 on the back side of the air outlet 43 can be suppressed as shown in FIGS. Accordingly, the airflow resistance in the louver case 31 due to the vortex caused by the turbulent flow is reduced, so that smooth air blowing from the air outlet 43 can be realized. In addition, since the influence of the turbulent flow on the air flow blown out from the air outlet 43 is reduced, the stability in the blowing direction of the conditioned air can be improved.

  As described above, preferred embodiments have been described as examples of the technology of the present disclosure. However, the technology of the present disclosure is not limited to this, and can also be applied to embodiments in which changes, replacements, additions, omissions, etc. are made as appropriate. In addition, the constituent elements described in the accompanying drawings and the detailed description may include constituent elements that are not essential for solving the problem. For this reason, it should not be immediately recognized that these non-essential components are essential because they are described in the accompanying drawings and detailed description.

  For example, the following embodiment may be configured as follows.

  FIG. 12 is an exploded cross-sectional view of the vehicle air blowing device 1 according to a modification. In the said embodiment, although the air blowing apparatus 1 gave and demonstrated the structure where the duct member 5 and the louver case 31 were combined as an example, it is not restricted to this. For example, as shown in FIG. 12, the air blowing device 1 including the duct portion 3 and the air blowing portion 5 may be configured by combining a pair of halves 73 and 75 divided in the vertical direction. . In addition, the air blowing device 1 includes a body member formed by integrally forming the air blowing portion 5 and a part of the duct portion 3 (for example, the upper surface wall 13, the lower surface wall 15, and the front wall 19), and the duct portion 3. You may be comprised by the combination with the back member which forms the back wall 17. FIG.

The vertical fin 57 has, for example, a notch cut out in a U-shape at the back side corresponding to the air outlet 43, and both side portions of the notch in the vertical direction reach the front opening of the louver case 31. You may be made into the extended shape. In short, in the rear edge 61 of the vertical fin 57 located on the duct member 7 side, the portion corresponding to the outlet 43 in the middle in the vertical direction is more air-blowing than the portions on both ends in the vertical direction. It is only necessary that the space 63 is formed on the duct member 7 side in the air blowing portion 5.

  In the above embodiment, the duct member 7 has a rectangular cross section. However, the present invention is not limited to this. The cross-sectional shape of the duct member 7 may be, for example, a circular shape, an elliptical shape, a triangular shape, or other polygonal shapes.

  Moreover, in the said embodiment, although the relay duct extended from an air conditioner was connected to the duct member 7 from the right side, it is not restricted to this. The duct member 7 may be connected to a relay duct from the front as viewed from the passenger seat side, for example.

  Moreover, in the said embodiment, although the blower outlet 43 was provided in the passenger seat side in the instrument panel 101 so that a longitudinal direction might turn into the left-right direction, it is not restricted to this. The air blowing device 1 may be provided with the air outlet 43 such that the longitudinal direction is the vertical direction or the diagonal direction. The air blowing device 1 may be provided not only on the passenger seat side but also on the center console, the side door, the rear seat side, and the like.
