The thin plate 51 and the blade 71 are installed perpendicular to each other so that the blowing direction by the thin plate 51 and the blowing direction by the blade 71 are perpendicular to each other so that the occupant of the thin plate 51 and the blade 71 Adjust the position so that it is blown in the desired direction.

The air blowing control device for a vehicle of the present invention has the same function as described above.

It is assumed that the initial state of the vehicle air conditioner of the present invention is a sealed state, and when the passenger needs to adjust the air flow rate and the air flow direction in the initial state, the first adjustment member 21 is rotated. The thin plates 51 and the air damper 41 are operated.

First, the process of adjusting the wind direction by operating the thin plates 51 by operating the first adjusting member 21 will be described.

When the first adjustment member 21 is rotated at the initial position, the operation lever 31 rotates about the rotation shaft 34. Rotating the first adjusting member 21 also rotates the operating hole 23 formed inside the first adjusting member 21, and the agent inserted into the operating hole 23 as the operating hole 23 rotates. 1 The thin plate actuating pin 53 of the actuating member 52 moves to the point where the through-holes formed in the actuating hole 23 and the frame 11 cross each other. As shown in FIG. 2, when the first adjustment member 21 is rotated in the clockwise direction, the intersection point of the through hole of the operating hole 23 and the frame 11 moves opposite to the direction in which the first adjustment member 21 rotates. . At this time, the thin plate actuating pin 53 of the first actuating member 52 inserted into the actuating hole 23 moves along the intersection of the actuating hole 23 and the through hole, and when the thin plate actuating pin 53 moves, 1 The thin plate 51 hinged to the operating member 52 is rotated and the end of the frame 11 starts to open, and the position of the thin plate 51 is adjusted according to the amount of rotation of the first adjusting member 21 to wind direction. This is regulated.

As shown in FIGS. 3 and 4, when the first adjusting member 21 is continuously rotated to blow in the desired direction, the thin plate operating pin 53 of the first operating member 52 is connected to the first adjusting member ( Sliding in the opposite direction to the rotational direction of the first adjusting member 21 while being inserted into the operating hole 23 of the 21, the thin plate 51 in accordance with the movement of the thin plate operating pin 53 formed on the first operating member 52 Rotate At this time, the rotation direction of the thin plate 51 is moved in the opposite direction to the rotation direction of the first adjusting member 21.

In the initial position, when the first operating member 52 is rotated clockwise as in FIGS. 2 to 4 in a state in which the front part of the vehicle air conditioner of the present invention is closed by the thin plate 51, the thin plate is counterclockwise. Since the wind direction is adjusted while rotating, the passenger can adjust the wind direction in the desired direction.

When the occupant rotates to the desired state while the thin plate 51 is closed, the air damper 41 also rotates at the same time. The air damper actuating pin 43 inserted into the first guide groove 32 formed in three stages is slid from the first guide groove 32 as the actuating lever 31 rotates, so that the air damper 41 rotates. Will rotate around.

When the first adjusting member 21 is rotated in the closed state as shown in FIG. 2, the air damper actuating pin 43 is moved while being inserted into the first guide groove 32 of the actuating lever 31, and thus the state of FIG. Become In this process, the air damper 41 at right angles to the blowing direction is parallel to the blowing direction, thereby controlling the blowing amount while being completely opened in a sealed state. Once the air damper 41 is completely opened, the air damper operating pin 43 is not moved even when the first adjusting member 21 is rotated to adjust the blowing direction as shown in FIG. 4, so that the air damper 41 is opened. State is maintained.

By rotating the above-described first adjusting member 21 in one direction, the process of adjusting the blowing amount adjusted by the blowing direction adjusted according to the rotation direction of the thin plate 51 and the opening degree of the air damper 41 is the above-mentioned. 1 By rotating the adjusting member 21 in the opposite direction, the reverse case is also possible.

The second adjusting member 61 installed perpendicular to the first adjusting member 21 separately from the thin plate 51 and the air damper 41 operating by the first adjusting member 21 to control the blowing amount and the blowing direction. Control the blowing direction using.

In the process of adjusting the blowing direction by the second adjusting member 61 using FIG. 5, when the occupant rotates by operating the second adjusting member 61, the second guide groove 62 also turns, and the second guide is rotated. As the groove 62 pivots, the inserted blade actuating pin 73 also pivots. As the blade operation pins 73 formed on the second operation member 72 change in position, the blades 71 fixed to the frame 11 at both ends are interlocked with the second operation member 72, thereby causing the blade 71 to be fixed. The position of the is changed to control the blowing direction. The blade 71 is installed perpendicular to the thin plate 51, so that the wind direction controlled by the thin plate 51 and the wind direction controlled by the blade 71 are perpendicular to each other.

The vehicle air conditioner according to the present invention having the configuration and action as described above can be expected the following effects.

Compared with the conventional vehicle air conditioner, it has a simple structure and can accurately adjust the air volume and the air direction with a small force.
