Have been.
[0042]
Next, the operation of the thus configured wind direction adjusting device will be described with reference to FIGS.
[0043]
3 and 4 show a state in which air supplied into the case 1a from a duct (not shown) is blown straight forward from the air outlet 2b. At this time, the inner surfaces of both sides of the case 1a and the inclined guide 5 are shown. Are substantially straight as shown in FIG. 4, so that the air flow is not disturbed.
[0044]
For example, to change the wind direction of the air upward from this state, the front louver 3 is rotated upward by holding the knob 3b of the front louver 3, and to change downward, the front louver 3 is rotated downward. This allows the air blown into the vehicle cabin from the air outlet 2b to be adjusted in the vertical direction.
[0045]
Next, when it is desired to change the direction of the air blown from the air outlet 2b to the left, the dial 8 is rotated clockwise as shown in FIG.
[0046]
As a result, the interlocking link 6 is moved to the left by the eccentric pin 8a of the dial 8, so that the guide pin 5b of the inclined guide 5 is pulled into the guide hole 1h while being pulled by the relief grooves 6a formed at both ends of the interlocking link 6. Is moved to the left, each of the inclined guides 5 is rotated leftward about the pin 5a as shown in FIG.
[0047]
At the same time, one link 9b of the center bending link 9 whose one end is fitted into the pin hole 8d of the dial 8 is moved forward, so that the other link 9c rotates clockwise around the shaft pins 10a and 10b of the shutter valve 10. The shutter valve 10 is also rotated leftward by the same angle α as each of the inclined guides 5.
[0048]
As a result, of the air flowing through the case 1a, the air that has hit the shutter valve 10 has its wind direction adjusted to the left by the shutter valve 10, and does not hit the shutter valve 10, but extends along the inner side surface of the case 1a. The air that has reached the vicinity is blown out from the air outlet 2b because the wind direction is guided to the left by the inclined guide 5 located inside the straight line A connecting the corner 1f and the left and right opening edges of the air outlet 2b. The air is directed to the left, and the front louver 3 is vertically rotated in this state, so that the vertical wind direction can be adjusted at the same time.
[0049]
When it is desired to change the wind direction of the air blown from the air outlet 2b to the right, the dial 8 is turned counterclockwise as shown in FIG.
[0050]
This causes the eccentric pin 8a of the dial 8 to move the interlocking link 6 rightward, so that the guide pin 5b of the inclined guide 5 is pulled into the guide hole 1h while being pulled by the escape grooves 6a formed at both ends of the interlocking link 6. Is moved rightward, and each inclined guide 5 is rotated rightward about the pin 5a as shown in FIG.
[0051]
At the same time, one link 9b of the center bending link 9 whose one end is fitted into the pin hole 8d of the dial 8 is moved backward, so that the other link 9c is counterclockwise centered on the shaft pins 10a and 10b of the shutter valve 10. The shutter valve 10 is rotated in the clockwise direction, and the shutter valve 10 is also rotated rightward by the same angle α as each of the inclined guides 5.
[0052]
As a result, of the air flowing through the case 1a, the air that hits the shutter valve 10 is adjusted to the right by the shutter valve 10, so that the air does not hit the shutter valve 10 and extends along the inner side surface of the case 1a. Since the air that has reached the vicinity is guided to the right by the inclined guide 5, the air blown out from the air outlet 2b goes to the right, and the front louver 3 is vertically rotated in this state. At the same time, the wind direction in the vertical direction can be adjusted.
[0053]
Further, when the dial 8 is further rotated counterclockwise from this state, one of the center bending links 9 is further moved rearward, so that the shutter valve 10 is further rotated, and the inside of the case 1a is shown in FIG. As shown in the drawing, the air blown out from the air blowout port 2b can be shut off.
[0054]
On the other hand, FIG. 8 shows a modification of the inclined guide 5, and this modification will be described below.
[0055]
In the left and right direction of the air blown out from the air outlet 2b, the rightward adjustment is much more frequent than in the leftward direction. This is because a vehicle having a steering wheel provided on the right side, such as a domestic automobile. In this case, since the driver sits on the right seat, the frequency of adjusting the wind direction toward the driver increases.
[0056]
Therefore, in the modification shown in FIG. 8, a fixed inclined guide 5 is provided on the right side of the opening of the case 1a, and a fixed guide 12 is provided on the left side. The fixed guide 12 turns the shutter valve 10 counterclockwise. When the wind direction is adjusted to the right by rotating the shutter valve in the right direction, the shutter valve 10 is formed in a triangular prism shape having an inclined surface 12a having substantially the same angle as the shutter valve 10, and is attached to the inner surface of the downstream opening 1c of the case 1a. It is fixed by means.
[0057]
The corner 1f of the extension 1d provided on the inclined guide 5 is chamfered 1k at substantially the same angle as the inclined surface 12a of the fixed guide 12 in order to reduce the air resistance. By rotating in the circumferential direction, it is possible to adjust the wind direction of the air blown out from the air blow-out port 2b to the right, and the wind direction controllability is reduced as compared to the right direction. In addition, the wind direction can be adjusted leftward, and one of the inclined guides 5 is a fixed inclined guide, and the other is a fixed guide 12, thereby eliminating the need for the interlocking link 6 and the like. Accordingly, the cost associated with this can be reduced.
[0058]
In the above embodiment, the front louver 3 is provided in the horizontal direction and the shutter valve 10 is provided in the vertical direction. However, the front louver 3 may be provided in the vertical direction and the shutter valve 10 may be provided in the horizontal direction. The front louver 3 can adjust the wind direction in the left-right direction, and the shutter valve 10 can adjust the wind direction in the vertical direction.
[0059]
