That is, when the two groups of vertical blades 11 are parallel to each other diagonally forward as shown in FIG. 9 and have the parallel wind characteristic of diagonally forward as shown in FIG. When the dial 13 is operated to rotate the first pulley 20 in the counterclockwise direction by 5 ° as shown, the second pulley 21 also moves in the same direction (counterclockwise) by 10 °.
The air distribution characteristic of the air that is rotated and is blown out from a single vertical blade group has a wide wind characteristic that diffuses forward as shown in FIG. Wide wind is blown toward the occupant from the outlet through the vertical blade group 11. If the turning operation of the dial 13 is further advanced, the left and right wide winds intersect at the front of the occupant to increase the air volume toward the occupant, and at the same time, it is possible to direct a part of the air volume to the left and right sides of the occupant.

FIG. 12 shows a third wind direction adjusting device 1 of the present invention.
The operating mechanism of the embodiment is shown, and according to the figure, unlike the above-described first and second embodiments, the dial 13 and the two sets of vertical blades 1 are provided.
1 and are separated. Rotating shafts 17a and 17b are fixed to the lower surfaces of the two sets of vertical blades 11, and first and second sliding gears 23a and 23b having the same diameter are fixed to the rotating shafts 17a and 17b, respectively. Has been done. A rotating shaft 15 is provided at the center of the upper surface of the dial 13,

Further, the pulleys 25a and 25b have first and second elliptical pulleys 27a and 27b having the same shape via the first and second belts 26a and 26b, respectively.
Linked to First and second elliptical pulleys 27a, 27 connected through first and second belts 26a, 26b
b are arranged so as to have a phase difference of 90 ° from each other.
Rotational shafts 28a and 28b are also provided on the upper surfaces of the first and second elliptical pulleys 27a and 27b, respectively.
At the upper ends of 8a and 28b, the first and second bevel gears 23 are provided.

In the wind direction adjusting device 1 according to the third embodiment provided with such components, two sets of the above-mentioned vertical blade groups 11 are provided by a bottom portion (not shown) of the casing 10 and an appropriate supporting member.
It is rotatably disposed and supported as shown in FIG. 13 to 15
Is for explaining the operation of the wind direction adjusting device according to the third embodiment. For example, as shown in FIG. 13, all the blades of the two sets of vertical blades 11 are in a state of facing diagonally forward in parallel. At this time, when the dial 13 is operated to rotate the first and second elliptical pulleys 27a and 27b by 45 ° in the same direction with a phase difference of 90 °, two sets of vertical blade groups 11 move forward as shown in FIG. In a state in which they are separated from each other, that is, the air distribution characteristics thereof, a single vertical blade group has wide air characteristics as shown in FIG. In this case, if the wind direction adjusting device 1 has the vertical blade group in which the two air outlets are symmetrically configured, it has a wide wind characteristic that diffuses toward the occupant.

When the two sets of vertical blades 11 are in the state shown in FIG. 13, when the dial 13 is operated to rotate the first and second elliptical pulleys 27a and 27b clockwise by 90 °, A state in which the pair of vertical blade groups 11 approach each other toward the front, that is, the wind distribution characteristic has a spot wind characteristic as shown in FIG. 8 in a single vertical blade group, and the rotation thereof is further increased. For example, the wind distribution has a spot-like characteristic with a narrower distribution. Thus, since the first and second elliptical pulleys 27a and 27b are arranged with a phase difference of 90 °, the rotation cycle of the two sets of vertical blade groups 11 is deviated, and Alternately turning large or small, it becomes possible to continuously change the air distribution characteristic from wide to spot despite the simple structure.

FIG. 15 shows the internal structure of the vertical blade group of the wind direction adjusting device 1 according to the fourth embodiment of the present invention. According to this embodiment, the dial 13 and the two sets of vertical blade groups 11 are separated from each other as in the third embodiment. On the lower surfaces of the two sets of vertical blades 11, the rotating shafts 17a, 1
7b is fixed, and first and second bevel gears 23a and 23b having the same diameter are fixedly mounted on the rotary shafts 17a and 17b, respectively. A rotating shaft 15 is provided at the center of the upper surface of the dial 13, and a pair of fan-shaped gears 29a and 29b are fixedly provided on the upper end of the rotating shaft 15 with a phase difference of about 180 ° in the same horizontal plane. There is.

The first and second moving gears 23a, 23b
The rotating shafts 17a, 17b of the dial 1 are rotatably supported at the bottom of the casing 10 at a predetermined interval.
As shown in FIG. 18, when one of the pair of fan-shaped gears 29a, 29b fixedly mounted on the upper end of the rotary shaft 15 protruding from No. 3 starts to mesh with the first or second moving gears 23a, 23b, the other is The dial 1 is set so as to be in a relational position where the meshing with the second or first bevel gears 23b, 23a is released.
3 is partly exposed to the outside and fitted in the center of the flange portion 14 of the casing 10.

In the fourth embodiment having the above structure,
While the pair of fan-shaped gears 29a and 29b, for example, as shown in FIG. 16, one fan-shaped gear 29b meshes with the second moving gear 23b to rotate in the clockwise direction to drive the first gear 23b, The driving force is not transmitted to the gear 23a, only one vertical blade group 11 rotates, and the air blown through both vertical blade groups 11 diffuses forward as shown in FIG. Therefore, the wind distribution characteristic at this time has the wide wind characteristic shown in FIG. 6, and the wide wind is blown toward the occupant from the two air outlets by the vertical blade group 11 which is symmetrically configured. .

When the dial 13 is further rotated clockwise from the state shown in FIG. 17, one fan-shaped gear 29b moves to the second position.
At the same time as the engagement with the moving gear 23b is disengaged, the other fan-shaped gear 29a starts to engage with the first moving gear 23a to rotate the other vertical blade group 11 in the counterclockwise direction.
As shown in (2), the two sets of vertical blades 11 are parallel to each other diagonally forward, and the air distribution characteristics are parallel wind. In this way, since the two sets of vertical blade groups 11 are rotated with their rotation cycles shifted from each other, various air distribution characteristics can be continuously obtained despite the simple structure.

In the above embodiment, in order to simplify the explanation,
Although the two sets of vertical blades are configured to have the same shape, it is possible to obtain more favorable air distribution characteristics for the occupant by forming the right and left blades and the number of vertical blades so as to be different from each other. Further, it is also possible to provide two or more sets of vertical blades with various air distribution characteristics by a single operating section, and naturally these configurations can also be applied to horizontal blades.

In each of the above embodiments, a device in which the dial operation is performed manually is illustrated, but the present invention controls the rotation of the motor by, for example, a switch operation without manually operating the dial operation, or It is also possible to automatically control the motor rotation to perform the dial operation.

[0031]

As is apparent from the above description, according to the wind direction adjusting device of the present invention, despite having a simple structure, it has various wind distribution characteristics such as diffused wind, parallel wind and spot wind. Air blowing can be obtained continuously. Moreover,
Since there is no member that obstructs the passage of both winds in the air blowing passage, the operation is smoothly performed without reducing the wind loss.
