Is a suction arm, 3 is a pair of left and right pivot arms formed on the upper rear side of the suction grill 2, 4 is a holder fitted to the front panel, 5 is an axis that fits into the holder 4 formed on the rotation arm 3, Reference numeral 6 denotes a hook formed on the side surface of the turning arm 3, and reference numeral 7 denotes a hook located on the side of the turning arm 3.
The hook holder 8 formed on the holder 4 for holding the shaft 4 is located below the shaft 5 and holds the shaft 5 in the front direction.
, 9 is a shaft holder which is located on the shaft 5 and is formed on the front panel for holding the shaft 5, and 10 is a fixing claw formed on the front panel for fixing the holder 4. .
The hook 6 and the hook holder 7 may be on either side or one side.

Next, the operation will be described. The indoor unit of the air conditioner is shown as in FIG. 1, in which the suction grill 2 is closed. FIG. 2 shows a state in which the suction grill 2 is rotated. In FIGS. 3 and 4, the rotating arm 3 is used.
And the vicinity of the shaft 5 of the turning arm 3 is shown in an enlarged manner.
The shaft 5 is held by a shaft holder 8 and a shaft holder 9 of the front panel 1 as shown in FIG.

When the lower end of the suction grill 2 is moved obliquely upward, the shaft 5 rotates about the shaft 5 while being supported by the shaft holding portion 8. At this time, when the suction grill is rotated to a predetermined diagonal direction, as shown in FIG. 4, the rotation arm side hook portion 6 is hooked on the hook portion holding portion 7, so that the suction grill 2 is held while facing obliquely downward. The adjustment of the holding force at this time can be adjusted by the shape of the hook holding portion 7. Since the mold for molding the holder 4 is small, the adjustment work can be easily performed.

Further, when the suction grill 2 is pulled forward, the shaft holding portion 8 is deformed, so that the shaft 5 gets over the shaft holding member 9 and the suction grill 2 can be removed from the front panel 1. The adjustment of the holding force at this time can be adjusted by the shape of the shaft holding portion 8. Since the mold for molding the holder 8 is small, the adjustment work can be easily performed.

On the contrary, when the suction grill 2 is mounted on the front panel 1, the removal is performed in the reverse order of removal. The shaft 5 is inserted between the shaft holder 8 and the shaft holder 9 in the horizontal direction with the suction grill 2. In this state, when the lower end portion of the suction grill 2 is rotated so as to move downward, the shaft 5 is supported by the shaft holding portion 8 and rotates about the shaft 5, and the suction grill 2 is further moved downward. When the suction grill 2 is turned to the right, the installation of the suction grill 2 is completed.

The holding tool 4 is fixed to the front panel 1 by the fixing claw 10 so as to be slidable to the left and right, so that even if the shapes of the front panel 1 and the suction grille vary slightly, the influence on the holding force is reduced. Can be reduced.

The holder 4 is made of a material different from that of the suction grille 2, especially a material having a low wear resistance and a low coefficient of friction. In this case, it is easy to reuse without pretreatment such as degreasing. Further, it is easy to use a material suitable for recycling or a recycled material for the front panel 1 and the suction grill 2.

Embodiment 2 FIG. In the first embodiment, the force for holding the suction grill 2 while obliquely facing downward is adjusted by the application portion holding portion 7, and the shaft 5 is held by the shaft holding portion 8 and the shaft holding tool 9. There is no need to be by the way. 5 and 6 show the second embodiment. FIG. 5 is a side view of a main part showing a state in which a suction grille is mounted on a front panel, and FIG. 6 is a view showing a state in which a suction grill is mounted on a front panel. It is a part side view. In the drawing, 1 is a front panel, 2 is a suction grill, 3 is a pair of left and right rotating arms formed on the upper rear side of the suction grill 2, 4 is a holder fitted to the front panel, 5 is a rotating arm 3 A shaft that fits in the holding tool 4 formed in the above, 6 is a hook formed on the side surface of the rotating arm 3,
Reference numeral 7 denotes a hook holder formed on the holder 4 which is located on the side surface of the rotating arm 3 and holds the hook 6. 8 denotes a holder 4 which is located below the shaft 5 and holds the shaft 5 in the front direction. , A fixing claw formed on the front side panel 1 for fixing the holder 4, a restraining rib 11 provided at a tip of the hook holding portion 7, and a restraining portion 12 formed on the front side panel 1. An end face 13 against which the rib 11 contacts is a bearing provided on the shaft holding portion 8. The hook 6 and the hook holder 7 may be on either side or one side.

When the lower end of the grill 2 is moved obliquely upward from the state shown in FIG. 5, the shaft 5 is supported by the bearing portion 13 of the shaft holding portion 8 and rotates about the shaft 5. At this time, when the suction grill 2 is rotated to a predetermined diagonal direction, as shown in FIG. 6, the rotation arm side hook portion 6 is hooked on the hook portion holding portion 7, so that the suction grill 2 is held while facing obliquely downward. At this time, the hook holding portion 7 is deformed, but the movement of the hook holding portion 7 is restrained by the restraining rib 11 hitting the end face 12, thereby generating a holding force. Adjustment of the holding force at this time,
It can be adjusted by the shape of the restraining rib 11. Since the mold for molding the holder 4 is small, the adjustment work can be easily performed. In addition, since the adjustment of the holding force is performed by adjusting the shape of the restricting rib 11, the size of the component can be reduced.

Further, when the suction grill 2 is pulled forward, the shaft holding portion 8 is deformed, and at the same time, the shaft 5 rides over the bearing portion 13 so that the suction grill 2 can be removed from the front panel 1.
