The operation part 35 is attached to the front part of the fin 32 . The operation part 35 is formed in a longitudinal shape in the left-right direction, and is integrally attached across the plurality of fins 32 . A support hole 35a for rotatably supporting the link shaft 32b of the fin 32 is formed in the rear portion of the operation portion 35. As shown in FIG. The support hole 35a is cut out in the rear portion of the operating portion 35 and is open rearward. In the present embodiment, support holes 35b for rotatably supporting link shafts 32b of fins 32 located on both sides are formed on both sides of the operation portion 35, respectively. Unlike the support holes 35a, these support holes 35b are notches formed on both sides of the operation part 35, and the link shafts 32b of the fins 32 positioned on both sides are inserted from a direction different from the direction of the support holes 35a.

Further, the operation portion 35 is formed with a knob portion 35c that is gripped by a user such as an occupant. The knob portion 35c is arranged in the central portion of the operation portion 35 in the left-right direction, which is the longitudinal direction.

The operating portion 35 is formed in a plate-like shape extending in the left-right direction over the knob portion 35c.

Next, operation of the first embodiment will be described.

When assembling the wind direction adjusting device 10, first, the fins 32 are assembled to the operating portion 35. As shown in FIG. At this time, among the plurality of fins 32, the link shafts 32b of the fins 32 other than the fins 32 on both sides are inserted into the support holes 35a of the operation portion 35 from behind. By inserting the link shaft 32b into the support holes 35b on both sides from the side, the direction of inserting the fins 32 on both sides and the other fins 32 into the operation part 35 is changed, and the operation part 35 is hardly pulled out from the fins 32. do.

Next, each fin 32 attached to the operating portion 35 is attached to the link 37 . The upper and lower rotating shafts 32a of the respective fins 32 are inserted into the support holes 40a of the upper and lower fin support portions 40 of the link 37 to be rotatably supported.

Further, the front side support shafts 33b of the upper and lower air distribution bodies 33 are inserted into the upper and lower support holes 41a of the connecting portion 41 of the link 37 to rotatably support them, and the upper and lower support holes 38a of the air distribution body link 38 are supported. On the other hand, the support shafts 33c on the rear side of the upper and lower air distribution bodies 33 are inserted and rotatably supported.

In this state, the support shaft 43a on the front side of the supported body 43 is inserted into the support hole 41b of the connecting portion 41 to rotatably support it, and the rear side of the supported body 43 is inserted into the support hole 38b of the air distribution body link 38. The support shaft 43a is inserted and supported rotatably. As a result, the link portion 34 integrally connects the fins 32 and the air distribution member 33 to form the adjustment portion 30 .

Then, the adjusting portion 30 is inserted into the body portion 16 through the mounting opening 20, and the supported body 43 is fitted to the support receiving portion 45. As shown in FIG. After that, the finisher 17 is attached to the main body 16 from the front, and the pressing part 46 is inserted into the support receiving part 45 from the front. is completed.

The wind direction adjusting device 10 is arranged so that the inlet 14 is connected to the air conditioner. The conditioned air from the air conditioner passes through the passage portion 13 , is distributed by the adjusting portion 30 , and is blown out from the outlet 15 . In the adjustment unit 30, the fins 32 distribute the air in the horizontal direction, and the air distribution members 33 distribute the air in the vertical direction.

At the neutral position shown in FIG. 1, the fins 32 face the outlet 15, and the upper and lower air distribution bodies 33, 33 are at approximately the same position in the front-rear direction. That is, the guide surfaces 33a, 33a of the air distribution bodies 33, 33 are located at substantially symmetrical positions in the vertical direction. Therefore, the guide surfaces 33a, 33a of the upper and lower air distribution bodies 33, 33 form an air passage so that the wind passing through the passage portion 13 is throttled toward the center in the vertical direction. is blown out from the outlet 15 along the fins 32.

When the operation portion 35 is rotated upward from the neutral position shown in FIG. 1 as shown in FIGS. 37, the parallel link mechanism consisting of the air distribution body link 38 and the air distribution bodies 33, 33 causes the upper air distribution body 33 to move rearward on the upstream side so as to retreat from the outlet 15, and the lower air distribution body 33 blows. It moves forward, which is the downstream side, so as to approach the exit 15 side. The upper air distribution body 33 is separated from the guide part 28 and positioned near the communication part 24 at a position where the upstream side of the guide surface 33a is substantially flush with the upper surface of the upstream main body part 22 when it is rotated to the maximum. . Further, the lower air distribution body 33 approaches the guide portion 28, and the downstream side of the guide surface 33a is located above the lower edge portion of the outlet 15 at the maximum rotated position. Therefore, when the air distribution bodies 33, 33 are displaced in the front-rear direction, which is the ventilation direction of the passage portion 13, the wind guided downward along the guide surface 33a of the upper air distribution body 33 located on the upstream side is extended upward. The air is guided upward along the guide surface 33a of the lower air distribution member 33 located downstream of the , and is blown upward from the outlet 15 along the fins 32 .

Similarly, when the operating portion 35 is rotated downward from the neutral position shown in FIG. 1 as shown in FIGS. By the parallel link mechanism consisting of the link 37, the air distribution body link 38, and the air distribution bodies 33, 33, the upper air distribution body 33 moves forward on the downstream side so as to approach the outlet 15, and the lower air distribution body 33 moves forward. It moves backward, which is the upstream side, so as to retreat from the blowout port 15 side. The upper air distribution body 33 approaches the guide portion 28, and the downstream side of the guide surface 33a is located below the upper edge portion of the outlet 15 at the maximum rotated position. In addition, the lower air distribution body 33 is separated from the guide part 28 and near the communication part 24 at a position where the upstream side of the guide surface 33a is substantially flush with the lower surface of the upstream main body part 22 when it is rotated to the maximum. Located in Therefore, when the air distribution bodies 33, 33 are displaced in the front-rear direction, which is the ventilation direction of the passage portion 13, the wind guided upward along the guide surface 33a of the lower air distribution body 33 located on the upstream side is extended. The air is guided downward along the guide surface 33a of the upper air distribution body 33 located above the upper downstream side, and is blown downward from the outlet 15 along the fins 32. As shown in FIG.

Further, when the operation portion 35 is operated in the left-right direction by pinching the knob portion 35c, each fin 32 connected to the operation portion 35 by the link shaft 32b moves in the same direction as the operation portion 35 about the rotation shaft 32a. It rotates left and right in the direction and distributes the wind left and right. For example, FIG. 5 shows a state in which the fins 32 are swung to one side from the neutral position.

Therefore, by combining the vertical air distribution caused by the advance and retreat of the air distribution bodies 33 and the horizontal air distribution caused by the rotation of the fins 32, the air direction adjustment device 10 can adjust the air direction in any direction.

As described above, according to the first embodiment, the fins 32 are arranged facing the outlet 15 of the passage 13 so as to be rotatable in the left-right direction, and the air distribution member 33 is arranged in the passage 13 so as to face the outlet 15 . By arranging them in pairs in the vertical direction so that they can advance and retreat against the fins 32, and by operating the rotation of the fins 32 and the advance and retreat of the air distribution member 33 with the operation unit 35 connected to the fins 32, the normal wind direction adjustment device can be set. Since there is no knob for operation to be set, the number of parts is small, and the fins 32 close to the air outlet 15 improve the air distribution performance in the left and right direction, and the air distribution body 33 allows the air to flow through the passage 13. can be formed with a minimum configuration to easily bend the wind in the vertical direction and to suppress ventilation resistance, thereby improving wind distribution performance with a simple configuration. Moreover, since the structure is simple, it can be manufactured at low cost.

Furthermore, since the airflow resistance of the air distribution member 33 is small, noise due to passage of air is less likely to occur.

The link 37 that connects the fins 32 and the air distribution body 33 is configured by the fin support portion 40 that rotatably supports the fins 32 and the connection portion 41 that connects the fin support portion 40 and the air distribution body 33. In addition, a simple configuration can be formed in which the fins 32 are rotated in the horizontal direction according to the operation of the operating portion 35 so that the air distribution member 33 moves forward and backward with respect to the outlet 15 .

By connecting the operation part 35 across the plurality of fins 32, the plurality of fins 32 can be rotated in conjunction with each other, and the wind distribution performance in the horizontal direction can be improved.

By forming the operation portion 35 in a plate-like shape extending in the left-right direction, the operation portion 35 is less likely to block the wind blown out from the blowout port 15, and the deterioration of the air distribution performance of the operation portion 35 can be suppressed. , it is difficult for the wind to be dispersed vertically by the operation part 35, and the concentrated wind can be blown forward from the outlet 15. - 特許庁

In addition, as in the second embodiment shown in FIG. 8, in order to improve the appearance of the fins 32 in the outlet 15, a lattice-shaped or mesh-shaped cover that interlocks with the fins 32 according to the operation of the operation part 35 is provided. 50 may be placed. Even in this case, the wind distribution performance can be ensured.

Further, in each embodiment, the operation unit 35 is not limited to being manually operated, and may be operated by an actuator such as a motor. In the case of electric operation in this way, since the large knob portion 35c and the like are not required, the operation portion 35 can be downsized, for example, the operation portion 35 can be hidden behind the cover 50 of the second embodiment. Also, the appearance can be further improved.
