Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indoor unit of an air conditioner, and more particularly, to the mounting of a guard wire provided through a group of left and right wind direction plates rotatably supported at an air outlet. Regarding the structure.

[0002]

2. Description of the Related Art An indoor unit of a conventional air conditioner includes a suction port 2 formed in a main body 1 as shown in FIGS. 3, 4, and 5A to 5C, for example. A heat exchanger 3 and a blower fan 4 are provided in an air passage connecting the air outlet 5 and the air outlet 5 is divided into left and right parts by providing at least one support 5c.
The support shaft 6a of the left / right airflow direction plate group 6 and the support shaft of the up / down airflow direction plate 7 are rotatably supported by the air outlet 5 from the rear side thereof, and are inserted into a plurality of insertion holes 6b provided in the left / right airflow direction plate group 6. The guard wire 8 bent into a substantially U shape is inserted, and both ends of the guard wire 8 are held by the holding portions 5e provided on the other side wall of the blow-out port 5, and the bent portion of the guard wire 8 is held. Holding member having holding hole 10a
10 and holds the locking portion 10b of the holding member 10 at the outlet 5
The guard wire 8 that is locked to the locking claw 5f provided on the one side wall 5a and is close to or in contact with the column 5c is a guard clamp.
It was clamped by 11.

As shown in FIGS. 4 and 5C, the guard wire 8 clamped by the guard clamp 11 is formed so that the clamp portion projects forward and is bent to extend along the support column 5c. It has a shape, and is clamped by the guard clamp 11 formed corresponding to the same shape and the column 5c.

However, the left and right wind direction plate group 6 is constructed such that after the guard wire 8 is inserted, both ends thereof are held by the holding portions 5e and the bent portions are held by the holding member 10. Therefore, the workability for assembling into the air blower casing that constitutes the blowout port 5 becomes poor, and it is necessary to bend and form the clamp portion of the guard wire 8, so that the guard clamp 11 and the holding member are formed. Since 10 is required, there is a problem that it becomes a cost disadvantage.

Incidentally, the stopper 9 is constructed so as to also serve as a cover attached to the driving means composed of the motor 12, whereby the left and right wind direction plate group 6 is formed.
Can be automatically reciprocally rotated by the motor 12, and the stopper 9 does not need to be separately manufactured and provided, which is a cost-effective configuration.

Further, since the guard wire 8 is formed by bending the length of the parallel portion thereof differently, and the holding portion 5e having a bottomed cylindrical shape is formed corresponding to the difference a. A through hole formed in the one side wall 5a at the tip of the guard wire 8 and an insertion hole formed in the left and right wind direction plate group corresponding to the through hole
6b can be easily and sequentially inserted, and the tip of the guard wire 8 can be accurately held by the holding portion 5e.

With the above structure, when the guard wire 8 is assembled, the support shaft 6a of the left and right air flow direction plate group 6 is rotatably supported on the blower casing forming the outlet 5, and then the guard wire is Both ends of 8 are successively inserted into the through hole of the side wall 5a of the outlet 5, and then sequentially inserted into the through holes 6b of the left and right wind direction plate group 6 to be fitted into the holding portion 5e. By assembling the stopper 9 so as to face the bent portion of 8, the left and right wind direction plate group 6
After the rotatably pivoting, the guard wire 8 can be easily assembled and the workability can be improved.

The upper and lower walls of the outlet 5 are shown in FIG.
As shown in (A) and FIG. 2 (B) and FIG. 4, both ends of the guard wire 8 when connected by at least one column 5c having a through hole 5d corresponding to the insertion hole 6b. Through the through hole 5b in succession to the work of inserting the through hole 6b
Since the guard clamp used in the prior art is not necessary because it is made to penetrate through, the workability for assembling the guard wire 8 can be improved, and
It is a cost-effective configuration.

With the above configuration, as shown in FIG. 1 and FIGS. 2A to 2C, when the upper and lower walls of the outlet 5 are not connected by the support column 5c, the guard wire 8 is formed.
When assembling, after pivotally supporting the support shaft 6a of the left and right wind direction plate group 6, both ends of the guard wire 8 are inserted into the through holes of the one side wall 5a of the air outlet 5, The guard wire 8 is inserted in the insertion hole 6b of the right and left air flow direction plate group 6 and fitted into the holding portion 5e, and the stopper 9 is assembled so as to face the bent portion of the guard wire 8 so that the guard wire 8 is moved in the longitudinal direction. The air conditioner is regulated so that it does not move and can be easily assembled.

When the upper and lower walls of the outlet 5 are connected by the support column 5c, both ends of the guard wire 8 are continuously penetrated through the through hole 5d to be inserted through the through hole 6b. The holding portion is inserted through the insertion hole 6b of the left and right wind direction plate group 6
An air conditioner fitted in 5e and assembled with the stopper 9 so as to face the bent portion of the guard wire 8 so that the guard wire 8 is prevented from moving in the longitudinal direction and can be easily assembled. Become an opportunity.
