The assembling of picture frame panel 30 of the present invention is efficiently, and this is because when fixation fastener 39, securing member 39 is pressed into escutcheon 34 on the transparent panel 35, and fixedly decoration 36 and decorative panel 34 simultaneously.

Front panel 20 comprises air inlet 15 that is positioned at central authorities and the service cover 24 that is positioned at the part of inside air inlet 15 belows, that be used for covering shell 10.Service cover 24 is parts of the profile of front panel 20.

By hook 27a and hole 17a, service cover 24 is releasably attached on the front panel 20.Service cover 24 and rhone 100 are fixed together and by bolt (not shown) or screw (not shown) and be fixed to front panel 20.

Especially, service cover 24 is fixed to front panel 20, makes one end 24a be positioned at the front of the following tube connector 52 of heat exchanger, is used for covering tube connector 52, and the other end covers terminal box 155, is used for to being equipped with unit 150 power supplies.

Terminal box 155 is separated with being equipped with unit 150, and connects by cable, is used for powering.

Especially, under the situation of terminal box 155 that needs repairing, can be only after removing service cover 24, rather than after fully removing front panel 20, just can keep in repair the terminal box 155 that is coated with service cover 14.

And, when indoor unit is installed, is not fully removing front panel 20, but only removing after the service cover, the refrigerant pipe is connected to heat exchanger and cable is connected to terminal box 155, thereby simplified the installation of indoor unit.

With reference to figure 9 or Figure 10, the cover part 27 of front panel 20 is by crooked backward, thus the forward edge of covering shell 10.

Housing 10 has frame 17 at the forward edge place that is coated with front panel 20, makes frame 17 insert in the cover part 27.

Especially, in this embodiment, when plate 20 is installed on the housing 10 in front, be positioned at the hook 27a on the inner surface of cover part 27 of front panel 20 and the hole 17a that is positioned on the frame 17 of housing 10 engages, thereby make the frame 17 of front panel 20 covering shells 10.

Therefore, the forward edge of housing 10 is coated with cover part 27 and is fixed to cover part 27, and this cover part 27 is posterior edges of front panel 20, thereby makes the joint line of housing 10 and front panel 20 not be displayed on the profile of indoor unit.

That is to say that cover part 27 is mounted to cover frame 17 fully, does not expose frame 17 on the profile of indoor unit, but exposes cover part 27.

Therefore, because the joint line of exposed housings 10 and front panel 20 not, thereby indoor unit has succinct profile, prevents that joint line from being made dirty by dust or impurity.

And because front panel 20 has covered the appearance of housing 10, thereby indoor unit of the present invention has the flatness of raising in the office, joint portion of plate 20 and housing 10 in front.

That is to say that outside if joint line is exposed to, then only when the abuts on surface of front panel 20 and housing 10 when being continuous, it is graceful that profile just seems, otherwise the flatness of profile will look ill.Yet, in the present invention, because the appearance of front panel 20 covering shells 10, thereby not needing to consider the flatness or the bonding state of joint line, this has increased the free degree of design.

Simultaneously, grid 21 (see figure 1)s before front panel 20 has on its front, and air inlet 15 has the filter 60 that is mounted thereon, and is used for filtering the air that flows to orifice plate 13.

Rotatable connecting rod 210 and support link 220 have an end 210a and 220a to be hinged on the support 212 and 322 on the picture frame pedestal 32, and the

other end

210b and 220b are hinged on the support 214 and 324 on the front panel 20.

Especially, support link 220 is longer than rotatable connecting rod 210.

And, under picture frame panel 30 and front panel 20 tight state of contact, turn end 210a of connecting rod 210 and support link 220 and the front that 220a is positioned at the

other end

210b and 220b.

In this case, by pin 400 is fixed to linkage 200, linkage 200, picture frame panel 30 and front panel 20 are combined.

Pin 400 is detachably fixed on the linkage 200.Described pin 400 comprises and being used for pin part 402 that is rotatably coupled to linkage coupling part 212 and the

projection

410 and 412 that is fixed to pin standing part 460.

Pin 400 also comprises retainer 404, and this retainer 404 is the steps that are positioned at the end of pin part 402, and it is used for linkage coupling part 212 is remained on a left side/right side.

Projection

410 and 412 is radially protruded from the neighboring of retainer 404.

A plurality of described protruding 410 and 412 radially protrude at interval from the neighboring of retainer 404 with rule, and a projection in a plurality of projectioies is kept by pin standing part 460.

Linkage coupling part 212 is

support

212a and 212b, and

support

212a and 212b open with the width interval greater than a left side/right width of linkage 200, and have relative through hole, so that pin part 402 passes.

Pin standing part 460 and linkage coupling part 21 are to open greater than a left side/right side width interval of projection 410.

Pin standing part 460 has pin and avoids groove so that at pin 400 when a left side/right is disposed in a side of linkage coupling part 212, pin 400 is not interfered.

The projection 464 of a protrusion from pin standing part 460 and

projection

410 and 412 is arranged, and be arranged in standing part 460 and

projection

410 and 412 another, the retaining

hole

414 and 416 that is used for holding and keeping this projection 464.

Purpose for convenience suppose that projection 464 is formed on the pin standing part 460, and retaining

hole

414 and 416 is formed in the

projection

410 and 412 along a left side/right.

Hook 202 and slit 204 are arranged on picture frame panel 30 and front panel 20, and they are used for picture frame panel 30 is remained on the front of front panel 20 and spaced apart.

In the present embodiment, hook 202 is formed on the top and side at the back side of picture frame pedestal 32, and slit 204 is formed at the front of front panel 20, is positioned at the position relative with hook 202.

Because the center of gravity of the picture frame panel 30 that is connected with linkage 200 is positioned at the front of front panel 20, if therefore picture frame panel 30 is not kept by hook 202 and slit 204, then in front under the effect of the hinge arrangement of the rotatable connecting rod 210 of a certain position of plate 20 fronts and support link 220, picture frame panel 30 is spaced apart with front panel 20.

And the support 324 that is connected with the other end of support link 220 has guide rail 225, and it is used for slidably/down motion of this other end 220b.

Guide rail 225 has hinge 223, and it is positioned at the other end place of the support link 220 that is movably disposed within guide rail 225, and the lower end of support 324 is closed, and is used for supported connecting rod 220.

Therefore, support link 220 is supported on the lower end of support 324 in rotating mode, and, if necessary, then upwards draw by other end 220b support link 220, support link 220 can be separated with support 324.

To describe a kind of being used for below pin will be inserted in state according to method in the linkage of indoor unit of the present invention and operator link mechanism.

When pin 400 is connected to linkage 200, pin 400 is positioned the side of

support

212a and 212b, and the part of linkage 200 is positioned between support 212a and the 212b, passes right side support 212b, linkage 200 and left side brackets 212a and sell 400 pin part 402 adjoining lands.

If pin part 402 passes right side support 212b, linkage 200 and left side brackets 212a dearly, then retainer 404 will be kept by the side of support 212b, thereby banking pin 400 moves along passing direction, rotatably linkage 200 and pin part 402 is coupled together thus.

In view of the above, if rotating dog 400 makes one 410 side that is located in pin standing part 460 in the

projection

410 and 412, then a projection 410 in the

projection

410 and 412 is in linkage coupling part 212, particularly move between right side support 212b and pin standing part 460.

When rotational pin 400, cause that projection 410 contacts and is pressed on the projection 464, at least one in feasible projection 410 and the pin standing part 460 is flexibly crooked, and flexibly recovers when being put into the retaining hole 414 that is arranged in projection 410 with protruding 464.

That is to say that by the rotation of pin 400 around pin part 402, projection 464 is kept by projection 410, and sell 400 and be fixed directly to picture frame panel 30 or pedestal 10, and do not use securing member any separation, for example screw etc. fully.

Therefore, after pin is connected to linkage, if promote picture frame panel 30 near front panel 20, make and when picture frame panel 30 is maintained at rotatable connecting rod 210 and support link 220, rotate that a part then picture frame panel 30, that be connected to rotatable connecting rod 210 and part picture frame panel 30, that be connected to support link 220 are with different mutually radius rotations.

And because support link 220 is longer than rotatable connecting rod 210, thereby when picture frame panel 30 travelled forward, after an end 210a of rotatable connecting rod 210 turned over predetermined angular, travelling forward of picture frame panel 30 had been subjected to the restriction of support link 220.

That is to say, with reference to Figure 12, when picture frame panel 30 is fixed to front panel 20, linkage 200 is installed to picture frame panel 30, like this, if spur picture frame panel 30 forward, then the maintenance effect of hook 202 and slit 204 is disengaged, thereby Rotary frame panel 30 under the restriction of linkage 200, the center of gravity of picture frame panel 30 moves simultaneously.

More specifically, when picture frame panel 30 owing to there is moment to act on the center of gravity of picture frame panel 30 during setting in motion, one end 210a of rotatable connecting rod 210 is pivotally lowered into the downside of support 214 from the upside of support 214, and an end 220a of support link 220 rotates a predetermined angular forward from the upside of support 324.
