In addition, the vertical fins are provided at predetermined intervals in the vehicle body width direction, and the horizontal fins are provided at predetermined intervals in the vertical direction, so that the entire area of the air outlets is opened substantially evenly.
Therefore, when the air conditioned by the air conditioner unit is blown out from the air outlet into the vehicle compartment, the air is blown out almost uniformly from the entire area of the air outlet.
For this reason, there is a possibility that air blown from the entire area of the blowout port may diffuse, and there remains room for improvement from the viewpoint of further enhancing the directivity of the blown air (air-conditioned air).

  This invention makes it a subject to provide the air blowing structure of the vehicle air conditioner which can improve the directivity of the air (air-conditioning wind) which blown off from the blower outlet while reducing a number of parts.

  The invention according to claim 1 includes an air conditioner unit that supplies air conditioned air to the passenger compartment, and a blower outlet is connected to the air conditioner unit via a duct, and the air outlet is connected to the passenger compartment from the blower outlet. In the air blowing structure of a vehicle air conditioner that blows out air that has been conditioned, vertical fins that project in the vertical direction are provided at the air outlet at a predetermined interval in the vehicle body width direction, and the vertical fins are provided in the air outlet. A central vertical fin provided in the center of the center and another vertical fin provided in addition to the center, the central vertical fin is integrally provided with a central horizontal fin projecting in the vehicle body width direction, The other vertical fins are integrally provided with other horizontal fins projecting in the vehicle body width direction, and a central space is formed at the center of the blow-out port by the central horizontal fins, and the intermediate fins are formed by the other horizontal fins. Other other space is formed of, wherein the central space has a configuration different from the central transverse fins and the other transverse fin to be larger than the other spaces.

  According to a second aspect of the present invention, the central lateral fin and the other lateral fin are formed so as to spread in the vehicle body width direction from the duct side toward the vehicle compartment side.

  A third aspect of the present invention includes an air conditioner unit that supplies air conditioned air to the passenger compartment, and an air outlet is connected to the air conditioner unit through a duct, and the air conditioning is performed from the air outlet to the vehicle interior. In the air blowing structure of a vehicle air conditioner that blows air, horizontal fins extending in the vehicle body width direction are provided at predetermined intervals in the vertical direction at the air outlet, and the horizontal fin is provided in the center of the air outlet. And a central vertical fin extending in the vertical direction is provided integrally with the central horizontal fin, and the other horizontal fin is provided integrally with the central horizontal fin. The other vertical fins extending in the vertical direction are integrally provided, and the central vertical fin forms a central space in the center of the outlet, and the other vertical fins have other spaces in addition to the center. Made is characterized in that the central space has a configuration different from the central longitudinal fins and the other vertical fin to be larger than the other spaces.

  A fourth aspect of the present invention is characterized in that the central vertical fin and the other vertical fins are formed so as to spread in the vertical direction from the duct side toward the vehicle compartment side.

In the invention according to claim 1, the central horizontal fin is provided integrally with the central vertical fin, and the other horizontal fin is provided integrally with the other vertical fin.
Thus, by providing the horizontal fin integrally with the vertical fin, the number of parts of the fin can be reduced, so that it is possible to facilitate fin part management and assembly work.

  Further, a central space was formed by the central lateral fin, and another space was formed by another lateral fin. The central lateral fin and the other lateral fin are configured differently so that the central space is larger than the other spaces.

In this way, by making the central space larger than other spaces, when the air conditioned by the air conditioner unit (air conditioner unit) is blown out from the air outlet to the vehicle interior, the central space has a lower pressure region than the other spaces. Become.
Therefore, the air guided to the other space can be guided to the central space of the low pressure region.
Thereby, since the air guide | induced from the duct can be collected in central space, the directivity of the air (air-conditioning wind) blown from the blower outlet can be improved.

In the invention according to claim 2, by forming the shape of the central lateral fin and the other lateral fins so as to spread in the vehicle body width direction from the duct side toward the vehicle compartment side, the dimension in the vehicle body width direction of each lateral fin Can be kept small on the duct side.
Therefore, when the direction of the vertical fin is adjusted, the vertical fin can be prevented from interfering with the central horizontal fin and other horizontal fins. Thereby, the adjustment range at the time of adjusting the direction of a vertical fin can be ensured largely, and the freedom degree of design can be raised.

Furthermore, by forming the shape of the central lateral fin and the other lateral fins so as to spread in the vehicle body width direction from the duct side toward the vehicle compartment side, the size of each lateral fin in the vehicle body width direction is reduced on the duct side.

On the other hand, by securing large dimensions in the vehicle body width direction of the central horizontal fin and other horizontal fins on the vehicle compartment side, the space on the vehicle compartment side can be made a high-pressure region, which is led to the space on the vehicle compartment side. Air can be smoothly guided to the central space (low pressure region).
In this way, air is smoothly guided to the space on the duct side, and the air guided to the space on the passenger compartment side is smoothly guided to the central space (low pressure region), so that air can be well collected in the central space (air conditioning). Wind) directivity can be further enhanced.

In the invention according to claim 3, the same effect as that of claim 1 can be obtained.
That is, in the invention which concerns on Claim 3, while providing the center vertical fin integrally with the center horizontal fin, the other vertical fin was provided integrally with the other horizontal fin.
Thus, by providing the vertical fin integrally with the horizontal fin, the number of parts of the fin can be reduced, so that the part management and assembly work of the fin can be facilitated.

  In addition, a central space was formed by the central vertical fins, and another space was formed by other vertical fins. The central vertical fin and the other vertical fin are configured differently so that the central space is larger than the other spaces.

Thus, by making the central space larger than the other spaces, the central space becomes a lower pressure region than the other spaces when the air conditioned by the air conditioner unit is blown out from the outlet to the vehicle interior.
Therefore, the air guided to the other space can be guided to the central space of the low pressure region.
Thereby, since the air guide | induced from the duct can be collected in central space, the directivity of the air (air-conditioning wind) blown from the blower outlet can be improved.

In the invention according to claim 4, the same effect as in claim 2 can be obtained.
That is, in the invention according to claim 4, the vertical vertical dimension of each vertical fin is formed by forming the shape of the central vertical fin and the other vertical fins so as to expand in the vertical direction from the duct side toward the passenger compartment side. Can be kept small on the duct side.
Therefore, when the direction of the horizontal fin is adjusted, it is possible to prevent the horizontal fin from interfering with the central vertical fin and other vertical fins. Thereby, the adjustment range at the time of adjusting the direction of a horizontal fin can be ensured largely, and the freedom degree of design can be raised.

Further, by forming the shape of the central vertical fin and other vertical fins so as to expand in the vertical direction from the duct side toward the vehicle compartment side, the vertical dimension of each vertical fin is reduced on the duct side, Large room can be secured.
By reducing the vertical dimension of the central vertical fin and other vertical fins on the duct side, the duct side space can be made a relatively low pressure region, and air is smoothly guided from the duct to the duct side space ( Flow).

On the other hand, by ensuring a large vertical dimension of the central vertical fin and other vertical fins on the passenger compartment side, the space on the passenger compartment side can be made a high pressure area, and the air guided to the space on the passenger compartment side Can be smoothly guided to the central space (low pressure region).
In this way, air is smoothly guided to the space on the duct side, and the air guided to the space on the passenger compartment side is smoothly guided to the central space (low pressure region), so that air can be well collected in the central space (air conditioning). Wind) directivity can be further enhanced.

Therefore, as shown in FIG. 5, the central vertical fin 41 is arranged so as to extend in the vertical direction at the center of the blower outlet 25 in the vehicle width direction (that is, in the vertical direction).

As shown in FIGS. 4 and 5, the central horizontal fin 42 has a left portion protruding substantially horizontally to the left from the central portion 41 c at the center in the vertical direction of the central vertical fin 41, and right to the right from the central portion 41 c. By projecting the part substantially horizontally, the left part and the right part are formed symmetrically with respect to the central vertical fin 41.
That is, the central horizontal fin 42 is provided integrally with the central portion 41c of the central vertical fin 41 and is formed so as to protrude substantially horizontally from the central portion 41c in the left-right direction (vehicle body width direction).

The vehicle interior side end portion 42a and the duct side end portion 42b are each formed in a convex arc.
The left part 42c and the right part 42d are each formed in a concave arc.
Here, the width dimension W1 of the passenger compartment side end part 42a is formed larger than the width dimension W2 of the duct side end part 42b.
Therefore, the central lateral fin 42 is formed in a substantially fan shape so as to spread in the vehicle body width direction from the duct side end portion 42b on the duct side toward the vehicle compartment side end portion 42a on the vehicle compartment 17 side.
Thereby, the dimension of the center horizontal fin 42 in the vehicle body width direction can be kept small on the duct side end portion 42b side.

  As shown in FIGS. 4 to 5, the left fin body 38 is integrated with the left vertical fin 51 (vertical fin, other vertical fin) 51 provided on the left side in the vehicle body width direction in the air outlet 25, and the left vertical fin 51.

It is rotatably supported on the left side 33b in the width direction.
Therefore, as shown in FIG. 5, the left vertical fin 51 is disposed so as to extend in the vertical direction on the left side in the vehicle body width direction in the outlet 25 (that is, vertically).

As shown in FIGS. 4 and 5, the upper left horizontal fin 52 is provided in the upper portion 51 d above the center portion 51 c of the left vertical fin 51 by a height dimension H1.
The central part 51 c of the left vertical fin 51 is located at the same height as the central part 41 c of the central vertical fin 41.

The left part protrudes substantially horizontally from the upper part 51d of the left vertical fin 51 to the left, and the right part protrudes substantially horizontally from the upper part 51d to the right, so that the left part and the right part are left vertical fins 51. Are formed symmetrically.
That is, the upper left horizontal fin 52 is provided integrally with the upper portion 51d of the left vertical fin 51, and is formed so as to protrude in the left-right direction (vehicle body width direction) from the upper portion 51d.

  As shown in FIG. 8, the upper left lateral fin 52 includes a passenger compartment side end 52 a arranged on the compartment 17 side, a duct side end 52 b arranged on the duct 13 side, and a duct side end 52 b. It has a left side portion 52c extending from the left end to the left end of the compartment side end portion 52a, and a right side portion 52d extending from the right end of the duct side end portion 52b to the right end of the compartment side end portion 52a.

The vehicle interior side end 52a and the duct side end 52b are each formed in a convex arc.
The left part 52c and the right part 52d are each formed in a concave arc.
Here, the width dimension W3 of the passenger compartment side end 52a is formed larger than the width dimension W4 of the duct side end 52b.
Accordingly, the upper left horizontal fin 52 is substantially fan-shaped so as to spread in the vehicle body width direction from the duct side end 52b on the duct side toward the vehicle interior side end 52a on the vehicle compartment 17 side, like the central horizontal fin 42. Is formed.
Thereby, the dimension of the upper left horizontal fin 52 in the vehicle body width direction can be kept small on the duct side end portion 52b side.

As shown in FIGS. 4 and 5, the lower left horizontal fin 53 is provided in the lower portion 51 e below the center portion 51 c of the left vertical fin 51 by a height dimension H1.
Since the upper left horizontal fin 52 and the lower left horizontal fin 53 are members of the same shape, the upper left horizontal fin 52 will be described in detail below, and the detailed description of the lower left horizontal fin 53 will be omitted.

The right fin body 39 is provided at a position symmetrical to the left fin body 38.
The right fin body 39 includes right vertical fins (vertical fins, other vertical fins) 61 provided on the right side in the vehicle body width direction in the air outlet 25, and upper and lower right horizontal fins (one integrated with the right vertical fin 61). Other lateral fins) 62 and 63 are provided.

The right vertical fin 61 is a member having the same shape as the left vertical fin 51. The upper and lower right lateral fins 62 and 63 are members having the same shape as the upper and lower left lateral fins 52 and 53.
Therefore, detailed description of the right vertical fin 61 and the upper and lower right horizontal fins 62 and 63 is omitted.

Here, the central vertical fin 41, the left vertical fin 51, and the right vertical fin 61 are provided in the air outlet 25 at a predetermined interval S1 in the vehicle body width direction.
The predetermined interval S1 can be arbitrarily determined.

The central vertical fin 41 is provided with one horizontal fin (that is, the central horizontal fin 42).
Further, the left vertical fin 51 is provided with two horizontal fins (that is, the upper left horizontal fin 52 and the lower left horizontal fin 53).
In addition, the right vertical fin 61 is provided with two horizontal fins (that is, the upper right horizontal fin 62 and the lower right horizontal fin 63).

  Therefore, the number of fins of the central lateral fin 42 can be made smaller than the number of fins of the upper left lateral fin 52 and the lower left lateral fin 53, and further, the number of fins of the upper right lateral fin 62 and the lower right lateral fin 63 can be made smaller.

As shown in FIGS. 5 and 8, by reducing the number of fins of the central lateral fin 42, a large space in the central region (central space) 65 in which the central lateral fin 42 is provided can be secured.
The central region 65 is formed at the center of the air outlet 25.
Here, the width dimension W3 of the upper left lateral fin 52 (vehicle compartment side end portion 52a) and the lower left lateral fin 53 (vehicle compartment side end portion 53a) is the width dimension of the central lateral fin 42 (vehicle compartment side end portion 42a). It is set smaller than W1.
Therefore, since it is possible to suppress the upper and lower left horizontal fins 52 and 53 from entering the left central region 65, a larger space in the left central region 65 can be secured.

Further, the width dimension W3 of the upper right lateral fin 62 (vehicle compartment side end portion 62a) and the lower left lateral fin 63 (vehicle compartment side end portion 63a) is equal to the width dimension W1 of the central lateral fin 42 (vehicle compartment side end portion 42a). It is set smaller.
Therefore, since the upper and lower right horizontal fins 62 and 63 can be prevented from entering the right central region 65, a larger space can be secured in the right central region 65.

Furthermore, by increasing the number of fins of the upper left lateral fin 52 and the lower left lateral fin 53, the space of the left region (other space) 66 provided with the upper and lower left lateral fins 52, 53 can be kept small. .
Here, the width dimension W1 of the central lateral fin 42 (vehicle compartment side end portion 42a) is the width dimension of the upper left lateral fin 52 (vehicle compartment side end portion 52a) and the lower left lateral fin 53 (vehicle compartment side end portion 53a). It is set larger than W3.
Accordingly, since the central horizontal fin 42 can be extended between the upper left horizontal fin 52 and the lower left horizontal fin 53, the space of the left region 66 can be further reduced.

Furthermore, by increasing the number of fins of the upper right lateral fin 62 and the lower right lateral fin 63, the space of the right region (other space) 67 provided with the upper and lower right lateral fins 62, 63 can be kept small. .
Here, the width dimension W1 of the central lateral fin 42 (vehicle compartment side end portion 42a) is the width dimension of the upper right lateral fin 62 (vehicle compartment side end portion 62a) and the lower right lateral fin 63 (vehicle compartment side end portion 63a). It is set larger than W3.
Accordingly, since the central horizontal fin 42 can be extended between the upper right horizontal fin 62 and the lower right horizontal fin 63, the space of the right region 67 can be further reduced.

Thereby, as shown in FIG. 5, the central region 65 is formed larger than the left and right regions 66 and 67.
As described above, the central horizontal fin 42 is configured differently from the upper and lower left horizontal fins 52 and 53 and the upper and lower right horizontal fins 62 and 63 so that the central region 65 is larger than the left and right regions 66 and 67. Can do.

  Here, as an example in which the central horizontal fin 42 is configured differently with respect to the upper and lower left horizontal fins 52 and 53 and the upper and lower right horizontal fins 62 and 63, as described above, the number of fins may be different or the fin shape may be different. Is different.

That is, in order to make the number of fins different, in the first embodiment, the number of fins of the central lateral fin 42 is smaller than the number of fins of the upper and lower left lateral fins 52 and 53 and the number of fins of the upper and lower right lateral fins 62 and 63. It is set.
Further, in order to make the fin shape different, in the first embodiment, the width dimension W3 of the upper and lower left lateral fins 52 and 53 and the width dimension W3 of the upper and lower right lateral fins 62 and 63 are changed to the width dimension of the central lateral fin 42. The shapes of the upper and lower left lateral fins 52 and 53, the upper and lower right lateral fins 62 and 63, and the central lateral fin 42 are set so as to be smaller than W1.

  By forming the central region 65 larger than the left and right regions 66 and 67, when air is introduced from the duct 13 (see FIG. 1) to the outlet 25, the pressure receiving area (the area that receives the air pressure) in the central region 65. ) Can be ensured larger than the pressure receiving area of the left region 66 and the pressure receiving area of the right region 67.

Therefore, when air is led from the duct 13 (see FIG. 1) to the outlet 25, the wind pressure (air pressure) generated in the central area 65 of the large space is changed to the wind pressure (air pressure) generated in the left and right areas 66 and 67 of the small space. ) Can be kept lower.
That is, the central region 65 provided with the central lateral fin 42 can be a low pressure region.
Thereby, when air is guided from the duct 13 to the air outlet 25, the guided air can be collected in the central region 65, and the directivity of the air (air conditioned air) blown out from the air outlet 25 can be improved. .

Here, as shown in FIG. 4, the central fin body 37 includes a central vertical fin 41 and a central horizontal fin 42 provided integrally. In the left fin body 38, upper and lower left horizontal fins 52 and 53 are integrally provided on the left vertical fin 51. Further, in the right fin body 39, upper and lower right horizontal fins 62 and 63 are integrally provided on the right vertical fin 61.
Thereby, since the number of parts of the fin can be reduced, it is possible to facilitate fin part management and assembly work.

As shown in FIGS. 4 and 6 to 7, the central vertical fin 41, the left vertical fin 51, and the right vertical fin 61 are each formed in a disc shape in a side view.
Therefore, for example, when the left side portion 11b (see FIG. 1) of the instrument panel 11 is formed in an arc shape, the edge of each vertical fin 41, 51, 61 on the side of the compartment 17 (see FIG. 1) is on the left side. Since it can be along the part 11b, designability (designability) can be improved.

  As shown in FIG. 2, the wind direction adjusting means 27 includes a left / right wind direction adjusting unit 71 that adjusts the wind direction in the vehicle width direction, and a vertical wind direction adjusting unit 72 that adjusts the wind direction in the up / down direction.

The left and right airflow direction adjusting unit 71 slides the first operation knob 74 in the vehicle body width direction (left and right direction) as indicated by arrows AB, so that the central fin body 37 is centered on the upper and lower support pins 44 and 45. It rotates in the width direction as shown by arrow CD.
The first operation knob 74 is slidably supported on the instrument panel 11 (see FIG. 1) as indicated by arrows AB.
The rotation of the central fin body 37 is transmitted to the left and right fin bodies 38 and 39 via the link 75, and the left and right fin bodies 38 and 39 are rotated as shown by arrows CD in conjunction with the rotation of the central fin body 37. .

  That is, the left / right airflow direction adjusting unit 71 operates the first operation knob 74 as indicated by arrows AB, so that the center fin body 37 (center vertical fin 41) and the left and right fin bodies 38, 39 (left and right vertical fins 51). , 61) can be adjusted to change the wind direction in the vehicle width direction.

For example, by sliding the first operation knob 74 as shown by the arrow B, the orientation of the central vertical fin 41 and the left and right vertical fins 51 and 61 is adjusted so as to face the center side of the vehicle compartment 17 as shown in FIG. it can.
Thereby, the directivity of the air (air-conditioning wind) which blows off from the blower outlet 25 by the center vertical fin 41 or the left and right vertical fins 51 and 61 can be defined.

Here, as shown in FIG. 9, the central lateral fin 42 is formed in a substantially fan shape so that the width dimension W1 of the passenger compartment side end part 42a is larger than the width dimension W2 of the duct side end part 42b. Further, the left side portion 42c and the right side portion 42d are formed in a concave arc.
Therefore, the dimension in the vehicle body width direction of the central lateral fin 42 can be kept small on the duct side end portion 42b side.

The upper left horizontal fin 52 is formed in a substantially fan shape so that the width dimension W3 of the passenger compartment side end 52a is larger than the width dimension W4 of the duct side end 52b. Furthermore, the left part 52c and the right part 52d are formed in a concave arc.
Therefore, the dimension of the upper left lateral fin 52 in the vehicle body width direction can be kept small on the duct side end portion 52b side.

Similar to the upper left horizontal fin 52, the upper right horizontal fin 62 is formed in a substantially fan shape so that the width dimension W3 of the passenger compartment side end portion 62a is larger than the width dimension W4 of the duct side end portion 62b. Further, the left side portion 62c and the right side portion 62d are formed in a concave arc.
Therefore, the dimension of the upper right lateral fin 62 in the vehicle body width direction can be kept small on the duct side end portion 62b side.

As shown in FIG. 8, the dimensions in the vehicle body width direction of the central lateral fin 42, the upper left lateral fin 52, and the upper right lateral fin 62 are kept small on the duct 13 side.
Therefore, for example, as shown in FIG. 9, it is possible to prevent the end 17 f of the left vertical fin 51 from interfering with the left side 42 c of the central horizontal fin 42.
Furthermore, even when the orientation of the central vertical fin 41 and the left and right vertical fins 51, 61 is adjusted so as to be further directed toward the center of the vehicle compartment 17, the vehicle interior side end portion 41 d of the central vertical fin 41 has the upper right horizontal fin 62. Can be prevented from interfering with the left side portion 62c.

Therefore, the adjustment range S2 when adjusting the horizontal direction of the central vertical fin 41 and the left and right vertical fins 51 and 61 can be secured (expanded).
Further, when the central vertical fin 41, the left vertical fin 51, and the right vertical fin 61 are provided, the selection range of the predetermined interval S1 can be expanded.
Thus, the degree of freedom in design can be increased by expanding the selection range of the adjustment range S2 and the predetermined interval S1.

As shown in FIG. 2, the up / down airflow direction adjustment unit 72 slides the second operation knob 77 in the up / down direction as shown by an arrow E-F, so that the air outlet 25 has left and right support pins 78 (the left support pin 78 is It rotates as shown by an arrow GH in the vertical direction with an axis (not shown) as an axis.
The second operation knob 77 is supported by the instrument panel 11 (see FIG. 1) so as to be slidable as indicated by arrows EF.
By rotating the air outlet 25 as indicated by an arrow GH, the vertical direction of the central lateral fin 42, the upper and lower left lateral fins 52 and 53, and the upper and lower right lateral fins 62 and 63 can be adjusted.

For example, the vertical wind direction adjusting unit 72 operates the second operation knob 77 as shown by an arrow E to adjust the central horizontal fin 42 upward as shown in FIG. Can be changed to
Similarly, as shown in FIG. 10B, the upper and lower left horizontal fins 52 and 53 can be adjusted upward so that the wind direction is obliquely upward.

Further, like the upper and lower left horizontal fins 52 and 53, the upper and lower right horizontal fins 62 and 63 (see FIG. 4) can be adjusted upward so that the wind direction is obliquely upward.
Thereby, the directivity of the air (air conditioned wind) blown out from the outlet 25 by the central horizontal fin 42, the upper and lower left horizontal fins 52 and 53, and the upper and lower right horizontal fins 62 and 63 can be defined.

  Next, an example in which air is blown out from the air outlet 25 with the central vertical fin 41 and the left and right vertical fins 51 and 61 of the air blowing structure 15 of the vehicle air conditioner 15 facing in the longitudinal direction of the vehicle body is shown in FIGS. This will be explained based on.

As shown in FIG. 11A, air conditioned by the air conditioner unit 12 (see FIG. 1) flows through the duct 13 toward the outlet 25 as indicated by arrows J1 to J4.
In this state, the pressure receiving area (area receiving the air pressure) in the central region 65 is secured larger than the pressure receiving area of the left region 66 and the pressure receiving area of the right region 67.
Therefore, the wind pressure (air pressure) in the central region 65 is kept lower than the wind pressure (air pressure) in the left and right regions 66 and 67.
As described above, the pressure difference is generated in the central region 65 and the left and right regions 66 and 67, whereby the air in the left and right regions 66 and 67 can be converged and directed (concentrated) toward the central region 65.

Specifically, as shown in FIGS. 11A and 11B, the air guided to the left region 66 as indicated by the arrow J1 is directed toward the left central region 65 where the wind pressure (air pressure) is suppressed low. Guided as indicated by arrow K1.
On the other hand, the air guided to the left central region 65 as indicated by the arrow J2 is guided by the air guided to the left central region 65 as indicated by the arrow K1, and along the central vertical fin 41 as indicated by the arrow K2. Led.

Further, the air guided to the right region 67 as indicated by the arrow J4 is guided as indicated by the arrow K4 toward the right central region 65 where the wind pressure (air pressure) is kept low.
On the other hand, the air guided to the right central region 65 as indicated by the arrow J3 is guided by the air guided to the right central region 65 as indicated by the arrow K4, and along the central vertical fin 41 as indicated by the arrow K3. Led.

The air guided as indicated by the arrow K2 along the central vertical fin 41 merges with the air guided as indicated by the arrow K1 from the left region 66 toward the central region 65 on the left side, and the arrow L appears along the central vertical fin 41. It is guided as (1-2).
Similarly, the air guided as indicated by the arrow K3 along the central vertical fin 41 merges with the air guided as indicated by the arrow K4 from the right region 67 toward the right central region 65, and along the central vertical fin 41. Are guided as indicated by arrows L (3 to 4).

As shown in FIG. 12, the air led from the duct 13 to the air outlet 25 is collected in the central region 65 (see also FIG. 11B), and the arrow L (1-2) is entered from the central region 65 into the passenger compartment 17. , Can be blown out as indicated by arrows L (3-4).
Thus, the directivity of the air (air conditioned air) blown out from the air outlet 25 can be enhanced by collecting the air led to the air outlet 25 in the central region 65 and blowing it out.

  Here, as shown in FIG. 11A, the shape of the upper left lateral fin 52 is formed in a substantially fan shape so as to spread in the vehicle body width direction from the duct side end portion 52b toward the vehicle compartment side end portion 52a. Thus, the size of the upper left lateral fin 52 in the vehicle body width direction can be kept small on the duct side end 52b side and large on the vehicle compartment side end 52a side.

By reducing the size of the upper left lateral fin 52 in the vehicle body width direction on the duct side end portion 52b side, the space on the duct side end portion 52b side can be secured larger than the space on the vehicle compartment side end portion 52a side.
Therefore, in the left region 66, the space on the duct side end portion 52b side can be made a lower pressure region than the space on the vehicle compartment side end portion 52a side. Thereby, air can be smoothly guided (flowed) from the duct 13 to the space of the duct side end portion 52b as indicated by the arrow J1.

On the other hand, by ensuring a large dimension of the upper left lateral fin 52 in the vehicle body width direction on the vehicle compartment side end portion 52a side, the space on the vehicle compartment side end portion 52a side can be a high pressure region. As a result, the air guided toward the space on the vehicle compartment side end portion 52a side can be smoothly guided to the central region (that is, the low pressure region) 65 as indicated by the arrow K1.
In this way, air is smoothly guided to the space on the duct side end portion 52b side, and the air guided to the space on the passenger compartment side end portion 52a side is smoothly guided to the central region 65. Can be collected.

Similarly to the upper left horizontal fin 52, the lower left horizontal fin 53 and the upper and lower right horizontal fins 62 and 63 are formed in a substantially fan shape.
As a result, the air guided to the lower left lateral fin 53 and the upper and lower right lateral fins 62 and 63 is collected in the central region 65 by the lateral fins 53, 62 and 63 in the same manner as the upper left lateral fin 52. be able to.
As described above, the air guided to the upper and lower left lateral fins 52 and 53 and the upper and lower right lateral fins 62 and 63 is collected by the lateral fins 52, 53, 62, and 63 in the central region 65. The directivity of (air conditioning wind) can be further increased.

  Next, the outlet in a state where the central vertical fin 41 and the left and right vertical fins 51 and 61 of the air blowing structure 15 of the vehicle air conditioner are tilted with respect to the longitudinal direction of the vehicle body (that is, tilted in the vehicle body width direction). An example of blowing air from 25 will be described with reference to FIG.

As shown in FIG. 13, the orientation of the central vertical fin 41 and the left and right vertical fins 51, 61 is adjusted to a state inclined in the horizontal direction so as to face the center side of the passenger compartment 17.
In this state, air conditioned by the air conditioner unit 12 (see FIG. 1) flows through the duct 13 toward the outlet 25 as indicated by arrows M1 to M4.

In this state, the pressure receiving area (area receiving the air pressure) in the central region 65 is secured larger than the pressure receiving area of the left region 66 and the pressure receiving area of the right region 67.
Therefore, the wind pressure (air pressure) in the central region 65 is kept lower than the wind pressure (air pressure) in the left and right regions 66 and 67.

The air guided to the left region 66 as indicated by the arrow M1 is guided to the left central region 65 as indicated by the arrow N1.
On the other hand, the air guided to the left central region 65 as indicated by the arrow M2 is guided by the air guided to the left central region 65 as indicated by the arrow N1, and along the central vertical fin 41 as indicated by the arrow N2. Led.

Among the air guided to the right region 67 as indicated by the arrow M4, a part of the air is guided toward the right central region 65 as indicated by the arrow N4, and the remaining air is guided as indicated by the arrow N5.
On the other hand, the air guided to the right central region 65 as indicated by the arrow M3 is guided along the central vertical fin 41 as indicated by the arrow N3.

The air guided along the central vertical fin 41 as indicated by the arrow N2 merges with the air guided as indicated by the arrow N1 from the left region 66 toward the left central region 65, and along the central vertical fin 41, the arrow O2 It is guided as (1-2).
Similarly, the air guided as indicated by the arrow N3 along the central vertical fin 41 merges with the air guided as indicated by the arrow N4 from the right region 67 toward the right central region 65, and along the central vertical fin 41. Are guided as indicated by arrows O (3 to 4).
Further, the air guided as indicated by the arrow N5 is guided as indicated by the arrow O (5).

Therefore, the air guided from the duct 13 to the outlet 25 is collected in the central region 65 and the arrows O (1-2), O (3-4) and O It can be blown out as in (5).
Thereby, also in the state which inclined the direction of the center vertical fin 41 and the left and right vertical fins 51 and 61 to the horizontal direction, the directivity of the air (air-conditioning wind) which blows off from the blower outlet 25 can be improved.
