Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an automatic variable wind direction device, and more particularly to an automatic variable wind direction device for an air conditioner installed in a vehicle or a room.

[Prior art]

Conventionally, this type of automatic wind direction variable device has been constructed as shown in FIGS. 1a and 1b.
That is, in FIGS. 1a and 1b, a conventional automatic wind direction variable device 1 is disposed at an air outlet (not shown) of an air duct, and the device 1 is attached to a mounting frame 2.
It is equipped with four groups of a large number of vertical fins (vertical straightening plates) rotatably supported by upper and lower rotating shafts 3a and 3b. Rotation shaft 3a at the upper end of each vertical fin 4
is connected to a crank pin 6 via a crank 5, and each crank pin 6 is pivotally connected to one link bar 7. In addition, the rotating shaft 3b at the lower end
A manual lever 8 is fixed to one of them.

Further, in the mounting frame 2, a large number of horizontal fins (horizontal current plate) 9 are arranged in front of the vertical fins 4, and each horizontal fin 9 has a rotating shaft 10 attached to both ends thereof.
It is rotatably supported on the mounting frame 2 by a and 10b. Each of these horizontal fins 9 is connected by one link bar 12 which is pivotally connected to a pin 11 provided at one end thereof.

The conventional automatic wind direction variable device 1 is constructed as described above, and its operation will be explained next.

The group of vertical fins 4 is driven by automatic driving (reciprocating motion) of the link bar 7 in the directions of arrows P and Q, thereby deflecting the wind direction in the left-right direction in FIG. 1a. Note that manual operation of the four groups of vertical fins is performed using a manual lever 8.

In the horizontal fins 9, the link bar 12 is urged to reciprocate at the same time as the vertical fins move, and as a result, the horizontal fins perform reciprocating pivoting movements about the rotation axes 10a and 10b, and the wind direction changes upward and downward (see Fig. 1). (vertical direction at b)
be deflected. In addition, the manual operation of the horizontal fin 9 is as follows.
It has an integral protruding piece 13 partially formed on the front edge of the two horizontal fins 9, and is driven by rotating it directly by hand, and this force is applied to all the horizontal fins 9 via the link bar 12. The wind direction is manually changed simultaneously and in the same direction.

In such conventional automatic wind direction changing devices, the blowing direction of the vertical and horizontal fins is variable only in a certain direction (reciprocating motion), so if you try to change the wind direction in any direction, the structure becomes extremely complicated. There were flaws.

[Summary of the idea]

The present invention was made to eliminate the drawbacks of the conventional automatic wind direction variable device as described above, and by making the current plate easy to swing, it can be moved in any direction with a simple structure. The purpose of this invention is to provide an automatic wind direction variable device that can change the wind direction.

[Example of idea]

Hereinafter, the automatic wind direction variable device of the present invention will be described in more detail with reference to the accompanying drawings showing preferred embodiments thereof.

2a, 2b and 3 show an automatic wind direction variable device 20 according to an embodiment of the present invention. This automatic wind direction variable device 20 is installed in a duct 21, for example. That is, the automatic wind direction variable device 20 includes a mounting frame 22 that is attached to a duct 21 and has a cylindrical inner peripheral surface, and a cylindrical fixing member 23 is further slidably rotatable on the inner peripheral surface of this mounting frame 22. It is fitted. On the inner surface of the end of the fixed member 23 on the outlet side, there is a swinging member whose outer periphery forms part of a sphere (a member whose outer shape is obtained by cutting a sphere into rings).
24 is swingably attached by engaging projections 25a, 25b formed on the upper and lower outer circumferential surfaces, respectively, with holes 26 formed on the inner circumferential surface of the fixing member 23.

The swinging member 24 is formed into a ring shape, and its inner circumferential surface is also formed of a curved surface constituting a part of a sphere like the outer circumferential surface. Consistently fitted together. A large number of fins 29 extending in the horizontal and vertical directions and intersecting each other at right angles are provided in the central space of the current plate 28 . By the way, one end of a crank 30 is pivotally attached to the inner edge of the swinging member 24 on an axis perpendicular to the axis connecting the protrusions 25a and 25b, and the other end is pivoted to an eccentric position of the rotating disk 31. It is worn.

As shown in FIG. 3, a motor (DC motor) M is attached to the inner wall surface of the fixed member 23 so that a rotating shaft 32 is perpendicular to the direction of the inner passageway, and the rotating disk 31 rotates It is fixed to the shaft 32. In FIG. 3, reference numeral 33 indicates the mounting position of this motor M.

The operation of the automatic wind direction variable device of the above embodiment configured in this way will be explained.

When the motor M is energized and rotates, and the disk 31 rotates in the direction of arrow R, the crank 30 reciprocates in the directions of arrows S and T, causing the swinging member 24 to swing. As a result, the air blown out from the duct 21 is blown out to the outer periphery in a complicated direction by the rectifying plate 28. To summarize this operation, the position of the motor M is 0 degrees or 180 degrees with respect to the mounting frame 22.
When the air conditioner is in the position shown in FIG. 2, the reciprocating motion of the crank 30 drives the swinging member 24, and in the state shown in FIG.
At this time, depending on the position of the rectifying plate 28 (initial manual setting = resetting possible during driving), it swings upward, toward the front, or downward. Further, when set diagonally, it can be arbitrarily set from the right (or left) to the front, from the right (or left) bottom to the front bottom, and from the right (or left) top to the front top. Next) By manually turning the fixing member 23 and setting the motor M at 90 degrees, it is possible to swing up and down. In this way, depending on the position of the motor M, it is possible to swing in any direction.

As mentioned above, with the automatic wind direction variable device of this embodiment, it is possible to freely swing the air in any blowing direction up and down, left and right, and diagonally with a simple configuration. It is preferable that the materials of each part constituting this device, except for the motor, be made of synthetic resin molding material.

[Effect of idea]

As explained above, according to the present invention, the rectifying plate has a spherical configuration and is configured to be oscillated by a motor, so that the air can be blown out and swung in all directions in the front surface. The structure for this purpose is also extremely simple.
