It is configured so that it can be smoothly slid from the rear portion of the horizontal groove 4b toward the horizontal groove 4b and can be separated from the opening of the horizontal groove 4b.

Next, in the above structure, the second convex portion 9b is provided above the convex portion 9a of the front panel 5, and the second grill 9b is provided on the grill facing the gap between the convex 9a and the second convex 9b. When the three convex portions 8b are provided to lock the locking portions 6 and 7, the third convex portion
8b is inserted into the above-mentioned gap almost without any gap, whereby the grill 2 can be accurately attached to the front panel 5 so as not to rattle in the vertical direction. .

Further, the one convex portion 9a and the second convex portion 9b
Are formed integrally with the front panel 5 so that the dimensions and shape can be finished with high accuracy, and the configuration is advantageous in terms of cost. In addition, the other convex portion 8a, the third convex portion 8b, and the support shaft 3 are formed integrally with the grill 2 so that the dimensions and shape can be finished with high accuracy, and the configuration is advantageous in terms of cost. Has become.

With the above configuration, FIG. 1, FIG. 2 (A) and FIG. 2 (B), FIG. 3 (A) and FIG. 3 (B), and FIG. 4 (A) and FIG. 4 (B). , FIG. 5 (A) and FIG.
(B), when the grill 2 is attached,
The support shaft 3 is inserted through the opening of the horizontal groove 4a which can be seen, and slides to the rear end of the inclined groove 4b to support the shaft. The grill 2 is rotated to lock the locking portions 6 and 7. Since the grille 2 is locked, the grille attaching / detaching device of the air conditioner can be mounted accurately.

When the grill 2 is detached from the engaging portion 7 and rotated at a predetermined angle, the grill 2 is provided with the convex portions 8a provided on both sides of the grill 2 and the front panel 5.
Since it is held by the holding means composed of the convex portion 9a, the filter (not shown) detachably provided on the front panel 5 can be easily taken out downward. It becomes a grill attachment / detachment device for a harmony machine.

When removing the grill 2, the grill 2 is rotated further upward and the front panel 5 is removed.
And the support shaft 3 by the moving means including the convex portion 2a and the substantially vertical wall 5b provided on the upper end of the grill 2.
Since it is slid from the inclined groove 4a to the horizontal groove 4b while being rotated, and is separated from the opening, the grill 2 can be easily and accurately removed only by pulling it forward. It becomes the grill attaching / detaching device of the air conditioner.
