2. Description of the Related Art FIG. 6 is an exploded perspective view showing an example of a conventional air conditioner, and FIG. 7 is an enlarged sectional view of a main part showing an example of a conventional air conditioner. Mounting state,
(B) shows horizontal position removal, and (c) shows upward removal.
FIG. 8A is a perspective view of a main part showing another example of a conventional air conditioner, and FIG. 8B is an explanatory view. Hereinafter, a conventional air conditioner will be described with reference to the drawings.

Some suction grills 3 of the air conditioner main body 1 can be removed from the front panel 2 without using a tool so that a user can wash the suction grille when washing the same. FIG. 7 shows that after opening the suction grille 3 to a substantially horizontal position, the suction grille 3 is lifted up and the support shaft 3x is attached to the holding groove 2.
It is a rotatable and detachable structure that is detached from a.

[0004] Fig. 8 shows a structure in which the suction grille 3 is similarly opened to a substantially horizontal position, and then the knob is pulled to disengage the support shaft of the grill and lift it up to remove it.

In both of the above-mentioned conventional examples, when removing the suction grille 3, it is necessary to open the suction grille 3 to a substantially horizontal position.

However, it is necessary to reach to the upper part of the indoor unit installed at a high position on the wall, and it is difficult to remove the indoor unit. Further, the conventional example of FIG. 7 has a problem that if the suction grille 3 is vigorously opened, the suction grille 3 may suddenly come off and drop during the removal work. FIG. 8 shows a structure in which a knob 3y for fixing the support shaft 3x of the suction grille 3 to the holding groove 2a is provided to prevent this, but since the knob 3y is located above the air conditioner body 1, Since the opening and closing of the knob 3y is also performed at a high position, there is a problem that the operation may be difficult.
