Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner, and more particularly, to a structure of a louver for adjusting a wind direction.

[0002]

2. Description of the Related Art A conventional air conditioner is, for example, shown in FIG.
As shown in (B) and FIGS. 5 (A) and (B), a blower fan 3, a heat exchanger 4, etc. are provided in the air passage formed in the main body 1 and connecting the inlet 2 and the outlet 5. A shaft hole 6g corresponding to the support shaft 5a is provided on the support shaft 5a provided substantially in the center of both left and right walls of the outlet 5.
The louver 6 provided with is rotatably supported in the vertical direction.

With the above structure, the air sucked from the suction port 2 by the blower fan 3 is heat-exchanged by the heat exchanger 4, and the heat-exchanged air is adjusted in the wind direction by the louver 6 to blow the air out of the air outlet 5. The air was conditioned from inside the room.

However, with the above configuration, the louver 6
Rotates up and down with the support shaft 5a as a fulcrum, and blown air is blown up and down at a substantially uniform swinging angle, but there is a limit to the swinging angle, and temperature unevenness occurs in the upper and lower parts of the room. Had a problem.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems and provides an air conditioner capable of increasing the vertical swing angle of a louver without increasing the number of parts. The purpose is to provide.

[0006]

In order to solve the above-mentioned problems, a shaft provided on both side walls of an outlet and a plurality of blades in the horizontal direction, and a shaft fitted on the side shaft on both side walls. A louver in which a hole is formed, and the louver is rotatably supported by the support shaft. The shaft hole is opened in the front and rear directions to form a first shaft hole, a second shaft hole, and It is configured by a slit that connects the uniaxial hole and the second axial hole. Further, a structure is formed in which holes are formed near the slit and above and below the slit.
The width of the slit is made narrower than the diameter of the support shaft. Further, the shaft hole is provided in the rear portion from the center of the louver. Further, the blade is formed integrally with the louver.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION A support shaft, which is provided on both side walls of an air outlet, and a louver, which is provided with a plurality of blades in the horizontal direction and has shaft holes formed on both side walls to fit the support shaft, In the one in which the louver is rotatably supported by the support shaft,
Since the shaft hole is opened in the front and rear direction and is constituted by the first shaft hole and the second shaft hole, and the slits that connect the first shaft hole and the second shaft hole, the louver of the louver can be formed without increasing the number of parts. The air conditioner can increase the vertical swing angle.

Embodiments of the present invention will be described below with reference to the drawings. 1 (A) (B), FIG. 2 and FIGS. 3 (A) (B)
And, 1 is an air conditioner body installed on the floor, 2
Is a suction port provided on the front surface of the body 1, and 3 is a suction port 2
And a blower fan 4 for blowing air to the heat exchanger and the outlet provided inside the main body 1 facing the
A heat exchanger 5 provided between the air outlet and the air outlet is an air outlet for sending out the air that has been heat-exchanged by the heat exchanger toward the interior of the room. It is configured to include a cylindrical support shaft 5a protruding inward.

Reference numeral 6 denotes a louver formed integrally with a frame body having a plurality of blades in the horizontal direction of the air outlet 5, and the louver 6 has a slit opening in the front-rear direction at the center rear portion of the left and right side walls thereof. 6a is provided, and is connected to the front and rear of the slit 6a.
The shaft hole 6b and the second shaft hole 6c are provided.
The width of the slit 6a is formed to be slightly smaller than the diameter of the cylindrical support shaft 5a projecting from both the left and right walls of the outlet 5, while the slit 6a is slightly spaced above and below the slit 6a to form a reverse convex hole.
6d and convex holes 6e are provided symmetrically.

Further, semi-circular convex portions 6f are formed at the central rear end portions of the left and right walls of the louver 6, and the second shaft holes 6c are provided in the convex portions 6f. There is.

In the above structure, as shown in FIGS. 3 (A) and 3 (B), the slit 6a has holes 6 provided above and below it.
It has elasticity by d and 6e, and is configured so that the support shaft 5a can pass by applying a required force.
The first shaft hole 6b or the second shaft hole 6c is fitted in and can be moved to either shaft hole through the slit 6a.

As a result, by fitting the first shaft hole 6b, which is the first fulcrum, to the support shaft 5a, the louver 6 has a vertical swinging angle which is almost the same as the conventional one, and the second fulcrum, which is the second fulcrum. Two
By fitting the shaft hole 6c into the support shaft 5a, the swinging angle of the louver 6 in the up-down direction can be increased, and it becomes possible to prevent temperature unevenness in the room, especially in the up-down direction. There is.

[0013]

As described above, according to the present invention, the swinging angle of the louver in the vertical direction can be increased without increasing the number of parts, and it is more comfortable so as not to cause temperature unevenness in the room. It becomes an air conditioner.
