One wind direction adjusting motor 69 is used as the wind direction adjusting device 60. The wind direction adjusting device 60 provides a driving force to any one of the first vane 70 and the second vane 80 and the other one is interlocked with the first and second links 61 and 65.

The first vane 70 is rotated about the first rotation axis 71. And the second vane 80 is rotated about the second rotation axis 81. [ In other words, the first vane 70 and the second vane 80 are rotated about the respective rotation shafts 71 and 81, and the rotation angles are interlocked with each other.

In this embodiment, the first vane 70 is positioned on the lower side and the second vane 80 is positioned on the upper side of the first vane 70. [ At least one of the first vane 70 and the second vane 80 may open or close the discharge port 13. The positions of the first vane 70 and the second vane 80 may be changed.

In this embodiment, the second vane 80 opens and closes the discharge port 13. The first vane 70 may partially open and close the discharge port 13 and the second vane 80 may open and close the remainder of the discharge port 13 unlike the present embodiment. The first vane 70 disposed on the lower side may be arranged to open and close the discharge port 13 unlike the present embodiment.

In this embodiment, the first vane 70 and the second vane 80 are spaced apart from each other by a predetermined distance. However, unlike the present embodiment, the lower end of the second vane 80 is in contact with the first vane 70 .

The first vane 70 and the second vane 80 are formed to extend in the left-right direction of the main body 10.

The first vane 70 includes a vane plate 75 for guiding air discharged from the discharge port 13 and a first joint 73 protruding from the vane plate 75 and having a first rotary shaft 71 72).

The second vane 80 has the same structure as the first vane 70. The second vane 80 includes a vane plate 85 for guiding the air from the discharge port 13 and a second joint 81 formed to protrude from the vane plate 85, (82).

The first link 61 and the second link 65 are connected to the first joint 72, respectively.

The first rotation axis 71 is formed orthogonally to the first joint 72.

In the present embodiment, the first rotation axis 71 is arranged in the horizontal direction. The first rotating shaft 71 is orthogonal to the vane plate 75. The first rotating shaft 71 and the vane plate 75 are arranged in parallel. The first joint 72 protrudes toward the main body 10 and is coupled to the main body 10. The first vane 70 is rotated in the vertical direction about the first rotation axis 71.

The first rotating shaft 71 may be formed on both sides of the vane plate 75.

In this embodiment, the first vane 70 is provided with the driving force of the wind direction adjusting motor 69. The wind direction adjusting motor 69 provides a rotating force to the first rotating shaft 71 and the first vane 70 can be rotated at a predetermined angle by the rotational force of the wind direction adjusting motor 69.

The wind direction adjusting motor 69 may be a stepping motor and may maintain the position of the first vane 70 after being rotated by a predetermined angle.

A power transmitting member (not shown) may be installed to provide the driving force of the wind direction adjusting motor 69 to the first rotating shaft 71. The power transmitting member may be a gear, a chain, a belt, or the like. The structure for rotating the first rotation shaft 71 through the power transmitting member is a general technique to those skilled in the art, and thus a detailed description thereof will be omitted.

When the first rotation shaft 71 is rotated, operational force is transmitted to the second vane 80 through the first link 61 and the second link 65.

The first link 61 and the second link 65 are installed in parallel. The first link (61) forms a height difference with the second link (65). In this embodiment, the first link 61 is disposed on the outer side with respect to the joints 72 and 82, and the second link 65 is disposed on the inner side. The first link 61 may be disposed on the inner side and the second link 65 may be disposed on the outer side based on the joints 72 and 82 unlike the present embodiment.

One side of the first link 61 is rotatably engaged with the first joint 72 and the other side is rotatably engaged with the second joint 82.

The first link 61 has a first hinge shaft 62 hinged to the first joint 72 and a second hinge shaft 62 hinged to the second joint 82 at the other end. 63 are installed.

The second link 65 is provided at its one end with a 2-1 hinge shaft 66 hinged to the first joint 72 and at the other end with a 2-2 hinge shaft 67 hinged to the second joint 82 ) Is installed.

The 1-1 hinge shaft 62 and the 2-1 hinge shaft 66 may be rotated about the first rotation shaft 71. [ The 1-1 hinge axis 62 and the 2-1 hinge axis 66 form a first phase difference with respect to the first rotation axis 71.

The first 1-2 hinge shaft 63 and the 2-2 hinge shaft 67 can be rotated about the second rotation shaft 81. The first and second hinge axes 63 and 67 form a second phase difference with respect to the second rotation axis 81.

In this embodiment, the first link 61 and the second link 65 are made to have the same length. Therefore, the first phase difference and the second phase difference are the same. The first phase difference and the second phase difference may be differently formed by varying the lengths of the first link 61 and the second link 65, unlike the present embodiment.

The wind direction adjusting device 60 according to the present embodiment can eliminate the change point by adjusting the first phase difference and the second phase difference. The change point is a point at which the second joint 82 is rotated in the opposite direction, unlike the rotation direction of the first joint 72. In the case where only one link is provided, the rotational directions of the first joint 72 and the second joint 82 are kept the same in most sections. However, at a change point, which is a specific point, the direction of rotation can be reversed.

For example, when the first joint 72 is rotated clockwise about the first rotation axis 71, the second joint 82 is rotated counterclockwise in the counterclockwise direction at the change point while the first joint 72 is rotated clockwise. Instead of being rotated in the clockwise direction, or the rotation direction may be reversed and the rotation may be stopped.

When the stopped position of the first joint 72 or the second joint 82 is a change point, even if the driving force is transmitted to the first joint 72, the second joint 82 is not rotated in the same direction .

In this embodiment, the first link 61 and the second link 65, which form the phase difference, are arranged to eliminate the change point.

The wind direction adjusting device 60 according to the present embodiment is configured such that the first joint 72 and the second joint 82 are always moved in the same direction through the first link 61 and the second link 65 arranged to form the phase difference .

The first vane 70 is disposed on the upper side of the discharge port 13 and the second vane 80 is disposed on the lower side of the discharge port 13 in this embodiment.

The air from the discharge port 13 flows between the first vane 70 and the second vane 80. Cool air for cooling or hot air for heating is discharged from the discharge port (13).

The wind direction adjusting device 60 controls the wind direction adjusting motor 69 to adjust the discharge angles of the first vane 70 and the second vane 80 simultaneously.

For example, when cold air is discharged, as shown in FIG. 5, the cold air from the discharge port 13 can be guided by the upper surface of the first vane 70 to be discharged above the desired angle.

Since the cool air discharged from the discharge port 13 is lower in temperature than the indoor air, the cold air sinks to the floor of the room due to the temperature difference. In order to prevent this, the wind direction adjuster (60) can guide the direction of the cool air discharged from the discharge port (13) by the first vane (70).

The cool air is guided and discharged between the first vane 70 and the second vane 80. Herein, the discharge angle is adjusted according to the angle of the first vane 70 disposed at the lower side.

That is, although two vanes 70 and 80 are disposed, the discharge angle of the cool air is controlled according to the angle of the first vane 70 disposed substantially at the lower side.

6, the hot air from the discharge port 13 is guided by the lower surface of the second vane 70 to be discharged to a lower side than the desired angle.

Since the temperature of the hot air discharged from the discharge port 13 is higher than that of the room air, the temperature is raised to the ceiling of the room by the temperature difference. In order to prevent this, the wind direction adjusting device (60) can guide the direction of the hot air discharged from the discharge port (13) by the second vane (80).

The warm air is guided and discharged between the first vane 70 and the second vane 80. The discharge angle of the warm air is adjusted according to the angle of the second vane 80 disposed on the upper side.

Contrary to the cold air, the discharge angle of the warm air is controlled in accordance with the angle of the second vane 80 disposed substantially on the upper side.

Since the first vane 70 is disposed at the lower end of the discharge port 13, the air from the discharge port 13 flows to the upper side of the first vane 70. Since the second vane 80 is disposed at the upper end of the discharge port 13, the air from the discharge port 13 flows to the lower side of the second vane 70.

That is, most of the air from the discharge port 13 flows between the first vane 70 and the second vane 80.

The wind direction adjusting device 60 according to the present embodiment can simultaneously adjust the angles of the first vane 70 and the second vane 80 through one wind direction adjusting motor 69. [ Particularly, when the cold wind comes out, the wind direction adjusting device 60 can control the discharge angle of the cold wind through the first vane 70 and the discharge angle of the hot wind through the second vane 80 when the hot wind comes out There is an effect that can be.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. The scope of the present invention is defined by the appended claims rather than the foregoing detailed description, and all changes or modifications derived from the meaning and scope of the claims and the equivalents thereof are included in the scope of the present invention Should be interpreted.
