That is, when the frame panel 30 according to the present invention is fixed to the front panel 20, the link mechanism 200 is installed as shown in FIG. Pulling out the hook 202 and the fitting groove 204 is released and at the same time the center of gravity of the frame panel 30 is moved while the frame panel 30 is restrained by the link mechanism 200 is rotated.

In more detail, when a moment acts on the center of gravity of the frame panel 30 and the frame panel 30 starts to rotate, one end 210a of the rotary link 210 is connected to the bracket 214. The upper side is rotated to the lower side of the bracket 214, one end 220a of the support link 220 is rotated a predetermined angle from the upper side of the bracket 324 to the front.

In this case, the length of the rotary link 210 is shorter than that of the support link 220, the rotation of the support link 220 is larger than the rotation angle, one end 210a of the rotary link 210 When the lower than the position of the bracket 214 for supporting the rotary link 210, the movement of the frame panel 30 is stopped (Fig. 13).

Thus, when the user opens the frame panel 30 and observes the filter 60 or the inside of the front panel 20, the user does not have to support the frame panel 30.

As described above, the frame panel 30 according to the present invention does not have to support the lower end of the frame panel 30 when the user cleans the filter 60. The 60 can be easily replaced.

In addition, the service provider does not need to hold the frame panel 30 even when the service cover 24 of the front panel 20 is removed.

In addition, even when the user replaces the picture or picture of the frame panel 30, the frame panel 30 is protruded downward and is arranged to be lying toward the user, so that the user can easily replace the picture or picture. Do.

On the other hand, the rotation angle of the rotary link 210 and the support link 220 is determined according to the relative length of the rotary link 210 and the support link 220, it can be variously adjusted according to the product In addition, the separation distance protruding forward can also be set in various ways.

In particular, if one end 220a of the support link 220 is not lower than the bracket 324 supporting the support link 220, the frame panel 30 is firmly supported by the support link 220.

On the other hand, as shown in Figure 14, the user can extend the opening angle of the frame panel 30 by holding the lower end of the frame panel 30, and further open the frame panel 30 and then the front By rotating the support bar 280 installed in the panel 20 can be fixed to the opening angle of the more open frame frame 30.

Here, the support part 288 of the support bar 280 is inserted into the locking part 289 formed on the rear surface of the frame base 32 to support the frame panel 30.

Thus, when the frame panel 30 is further opened and fixed by the support bar 280, the user or assembler can more easily replace the filter 60, replace the service cover 24 and repair the indoor unit more easily. There is one effect.
