Description

[Technical Field]

[0001] The present disclosure relates to an air conditioner, and more particularly, to an indoor unit of an air conditioner installed on a ceiling.[Background Art]

[0002] An air conditioner is an apparatus that heatexchanges a sucked air and supplies the heat-exchanged air to a room.

[0003] An air conditioner includes an indoor unit having an intake port and a discharge port. The indoor unit is installed in an indoor space and supplies the sucked, heat-exchanged air to a room through the discharge port.

[0004] A vane that controls the airflow direction can be installed in the discharge port of the indoor unit. The vane can be movably disposed in the discharge port, and the airflow direction is controlled by the movement of the vane.

[0005] However, conventional air conditioners have a problem in that the vane's rotation path is inconsistent and it is not firmly fixed to a case, which resulted in a shortened lifespan. In addition, conventional air conditioners have a problem in that the vane is pulled downwards by gravity, which resulted in a lack of rigidity.

[0006] In addition, conventional air conditioners have a problem in that the range of airflow directions that can be implemented is restricted, because a link for rotating the vane restricts the rotation range of the vane.[Disclosure][Technical Problem]

[0007] An object of the present disclosure is to solve the aforementioned problems and other problems.

[0008] Another object of the present disclosure may be to implement various airflows of an air conditioner.

[0009] Another object of the present disclosure may be to improve the life of a vane.

[0154] The first guide portion 374 may be spaced apart from the bent portion 73 of the inner body 70. The curvature of the first guide portion 374 may be substantially the same as the curvature of the bent portion 73.

[0155] Referring to FIG. 8, the air conditioner 1 is described.

[0156] FIG. 8 sequentially illustrates the driving of the vane assembly 300 according to another embodiment of the present disclosure.

[0157] In a state where the driving of the indoor unit 1 is stopped, the vane 310 may be disposed parallel to the panel 10. The inner edge 3130 may be accommodated in the space formed by the side wall edge 74. The outer edge 3120 may be disposed in the vane accommodating portion 84. The vane body 3110 may be disposed in a horizontal direction. The fin 360 may be located closer to the second edge 377 than the first edge 376. The fin 360 may be located in the first guide portion 374. The link 340 may be inclined from the rotation shaft 330 toward the inner body 70.

[0158] When the indoor unit 1 starts driving, the vane 310 may be rotated downward. The outer edge 3120 may move downward, and the inner edge 3130 may move upward. The inner edge 3130 may face the body side wall 73 or the bent portion 72. At this time, the fin 360 may move toward the first edge 376.

[0159] The angle θ4, θ5, θ6 at which the vane 310 is inclined with respect to the horizontal direction may increase as the vane 310 rotates downward. As the fin 360 approaches the first edge 376, the angle θ4, θ5, θ6 at which the vane 310 is inclined with respect to the horizontal direction becomes larger.

[0160] Due to the above-described structure, the upright positioning of the vane 310 may be facilitated. In addition, the rotation range of the vane 310 may be increased. This may be because the guide 370 has a bent first guide portion 374, so that the movement path of the fin 360 passes through both the bent portion and the straight portion.

[0161] Although the present invention has been described with reference to specific embodiments shown in the drawings, it is apparent to those skilled in the art that the present description is not limited to those exemplary embodiments and is embodied in many forms without departing from the scope of the present invention, which is described in the following claims.

Claims

1. An air conditioner comprising: a case having a fan disposed therein; a panel which is disposed at a lower side of the case, and has a discharge port formed thereon; and a vane assembly disposed at the discharge port, wherein the vane assembly comprises: a vane rotatably disposed at the discharge port; a motor which rotates the vane; a fin which rotates with the vane as one body; and a guide having a slit into which the fin is movably inserted.

2. The air conditioner of claim 1, wherein the fin is moved along an extension direction of the slit, when the vane is rotated.

3. The air conditioner of claim 1, wherein the slit is extended in a direction intersecting with a rotation shaft of the vane.

4. The air conditioner of claim 1, wherein the fin protrudes from the vane.

5. The air conditioner of claim 1, wherein the vane assembly comprises: a rotation shaft coupled with the motor; and a link connecting the rotation shaft and the vane.

6. The air conditioner of claim 1, wherein the guide comprises: a first edge forming one end portion of the slit; and a second edge forming the other end portion of the slit, wherein the fin moves between the first edge and the second edge.

7. The air conditioner of claim 1, further comprising an inner body having a surface which is disposed at the discharge port to face the vane, and extends along an up-down direction.

8. The air conditioner of claim 7, wherein the inner body comprises: an inner guide extending in an up-down direction; and a bent portion extending from the inner guide toward the vane.

9. The air conditioner of claim 7, wherein the inner body comprises: a body side wall facing the vane; and a side wall edge which is inclined in a direction away from the vane from the body side wall, and provides a space where a distal end of the vane is located.

10. The air conditioner of claim 7, further comprising an outer body which is disposed at the discharge port to face the vane, and extends to an outside of the case.

11. The air conditioner of claim 10, wherein the outer body comprises: an outer guide which is bent to the outside of the case; and a corner portion which is formed on a lower side of the outer guide, and faces the vane.

12. The air conditioner of claim 10, wherein the outer body comprises: an outer guide which is bent to the outside of the case; and a vane accommodating portion which is formed on a lower side of the outer guide, and provides a space in which the vane is accommodated.

13. The air conditioner of claim 1, wherein the vane comprises: an inner edge facing a central portion of the case; and an outer edge facing in a direction opposite to the inner edge, wherein the guide comprises: a first edge facing the outer edge, when the fan stops; and a second edge facing the inner edge, when the fan stops, wherein the fin is located closer to the second edge than the first edge, when the fan stops.

14. The air conditioner of claim 1, wherein the vane stands upright in a vertical direction by a rotation of the motor.

15. The air conditioner of claim 1, wherein the guide comprises: a first edge facing an outside of the case; and a second edge toward a central portion of the case, wherein when the vane stands upright in a vertical direction, the fin is located closer to the first edge than the second edge.

16. The air conditioner of claim 1, further comprising an outer body having a protruding portion which extends in a bent manner toward an outside of the case, and faces the discharge port, wherein the vane comprises an inner edge which faces the protruding portion, when the vane stands upright in a vertical direction.

17. The air conditioner of claim 1, wherein the guide comprises: a first guide portion which is bent in an up-down direction; and a second guide portion which extends in a horizontal direction from the first guide portion.

18. The air conditioner of claim 17, wherein when the fan is stopped, the fin is located in the first guide portion.

19. The air conditioner of claim 17, wherein the vane assembly comprises: a vane body rotatably disposed at the discharge port; and a bridge connecting the vane body and the fin.

20. The air conditioner of claim 17, further comprising an inner body which is disposed at the discharge port to face the vane, and bent along an up-down direction, wherein the first guide portion is spaced apart from the inner body.
