Description

[Detailed Description of the Invention] The present invention relates to an assembly structure of a ceiling-mounted air conditioner.

Ceiling-mounted air conditioners are installed by hanging from the ceiling, so the top plate of the main unit has strength.
In reality, heavy components such as a heat exchanger and a blower are generally fixed to this top plate. As shown in FIG.
After placing the partition plate 6 on which the blower 5 is supported and the heat exchanger 7 on the top plate and fixing them with screws etc., the bottom plate 8 which also serves as a drain pan, the blow-off grill 9 and the suction The assembly work is facilitated by attaching the grill 10 and the like.

However, when the main body 11 of the ceiling-mounted air conditioner is connected to an outdoor unit (not shown) on the assembly line after assembly is completed and a test run is performed in this inverted state, dew water generated in the heat exchanger 7 is transferred to the top plate 4. 1, and is absorbed by the water-absorbing heat insulating material 12 such as glass wool. Therefore, the main body 11 was turned upside down as shown in FIG. Therefore, it is necessary to turn the main body 11 upside down on the line, and the exterior panels such as the top plate 4' and the bottom plate 8 are damaged during this operation.

In view of the above, the purpose of the present invention is to provide a ceiling-mounted air conditioner that allows trial operation with the main body in an inverted state.

In the structure of the present invention, a heat exchanger is fixed to the bottom plate of the main body via a waterproof heat insulating material, and a closable through hole is formed in the top plate above the heat exchanger. With this configuration, during a trial run, dew water from the heat exchanger can be discharged from the through hole without being accumulated in the main body, and during on-site operation, the through hole can be sealed to prevent air leakage.

The embodiment of the present invention will be explained below based on FIGS. 3 and 4. 14 is a waterproof material 14 that is pasted across the inner wall 15 of the top plate 4 and a heat insulating material 16 such as glass wool that is pasted to the wall. These two materials 14,
The heat exchanger 7 is fixed to the top plate 4 via a waterproof heat insulating material 17 formed by the heat exchanger 16. A reinforcing frame 18 is welded and sealed to the inner wall 15 of the top plate 4, and has the same length as the width of the top plate 4. A through hole 19 is bored in the center. 20 is a blind stopper made of synthetic resin that seals the through hole 19.

Therefore, as in FIG. 1, first the top plate 4 with through holes 19 formed integrally with or separately from the back plate 21 is placed on the conveyor 1 via the pallet 2 and the stand 3, and the top plate 4 A waterproof heat insulating material 17 is attached to the inner wall 15 of the heat exchanger 7, and the heat exchanger 7 is fixed to the top plate 4 with screws or the like via the heat insulating material 17. At the same time, the partition plate 6 on which the blower 5 is supported is fixed to the top plate 4 with screws or the like, and the reinforcing frame 18 is welded and sealed to the top plate 4. After that, the insulating bottom plate 8, which also serves as a drain pan, the outlet grill 9, the suction grill 10, etc. are attached, and the assembly work is completed.

When a trial run is carried out on the assembly line in this assembled state, the suction air flows as indicated by the solid arrow in FIG. At this time, since the dew water is sealed with the waterproof packing material 14, the insulation material 1
Moreover, since it is sealed by the reinforcing frame 18, it is all discharged from the through hole 19 without flowing to the blower 5 side.

After the trial run is completed, the through hole 19 is sealed with the stopcock 20 and shipped, and when installed on site in the normal state with the top plate 4 facing upward, air from the blower 5 will not leak and operation will be possible without any problems. can.

In addition, as a means of closing the through hole 19, a non-breathable heat insulating material may be attached instead of the blind plug 20. Also, if the top plate 4 is installed tightly against the ceiling wall during on-site installation, it will automatically close the hole 19. Since the through hole 19 is closed in this case, there is no need to provide a closing means.

As described above, the present invention has been constructed so that it is possible to test run the main body in the reversed state at the time of manufacturing and assembly, eliminating the need for the conventional work of turning the main body upside down on the assembly line, and eliminating the risk of damaging the exterior panel. It is useful because there is no such thing.
