Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an air conditioner, and more particularly to a method for attaching a top plate.
[0002]
[Prior art]
Conventionally, as shown in FIG. 1, a front plate 2 having a suction port, an air outlet 2a, and an axial fan 8a attached to the air outlet 2a, and left and right side plates 3 facing each other. 4, a top plate 5 provided with a downward flange 5a for attaching the rear plate, the front plate 2, and the left and right side plates 3, 4 to the periphery, and a heat exchanger 9 placed on the upper surface via a dew tray. As shown in FIGS. 5 and 6, the air conditioner 1 including the first bottom plate 6 fixed to the top plate 5 and the second bottom plate 7 that forms the bottom together with the first bottom plate 6, While welding bolts 21 are welded to the top plate 5, insertion holes 10 a corresponding to the welding bolts 21 are provided in the bent end portions of the suspension fittings 10 fixed to the first bottom plate 6.
The assembly procedure is as follows. First, the side plate of the rear plate (not shown), the front plate 2 on which the fan casing 8 containing the axial flow fan 8a is mounted in advance, and the left and right side plates 3, 4 are fixed with screws 20 or the like. Assembling the frame, the heat exchanger 9 is placed on the first bottom plate 6 to which the hanging bracket 10 is fixed via a dew tray.
Next, the assembled frame is arranged on the top plate 5 arranged with the upper surface facing down, and is fixed with the screw 20 from the insertion hole of the flange 5a, while being fixed to the first bottom plate 6. A welding bolt 21 to be welded to the top plate 5 is inserted into the insertion hole 10a of the hanging metal fitting 10, and the nut 22 is screwed to fix the first bottom plate 6, and then the first bottom plate 6 and the second bottom plate 6 are fixed. The bottom plate 7 was fixed to the frame and completed.
However, in this configuration, simple maintenance can be handled by removing the bottom plate of the air conditioner.For example, when the air conditioner is placed on the floor and you want to look inside from the top plate side, it is welded to this top plate. Since the first bottom plate on which the heat exchanger is mounted on the welding bolt is fixed via the hanging bracket, the top plate cannot be removed because the fastening of the welding bolt and nut cannot be removed from the top plate side. There was a problem that maintenance was not possible.
[0003]
[Problems to be solved by the invention]
An object of the present invention is to solve the above-described problems and to provide an air conditioner that can be attached and detached from the top plate side and has improved maintainability.
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention has a back plate having a suction port, a front plate having an air outlet, and an axial fan mounted corresponding to the air outlet, left and right side plates facing each other, and a peripheral edge. A top plate formed with a downward flange for attaching the back plate, the front plate, and the left and right side plates, and a heat exchanger placed on the top surface via a dew tray and fixed to the top plate by a hanging bracket. In the air conditioner composed of the bottom plate and the second bottom plate that forms the bottom surface of the housing together with the first bottom plate,
A multi-surface fixture having at least two attachment surfaces formed with insertion holes corresponding to positions of the top plate corresponding to the suspension fittings and screw holes to be screwed to the respective surfaces from different directions is provided. A screw is screwed into the screw hole of one mounting surface of the multi-surface mounting tool from the insertion hole of the top plate, and is fixed to the screw hole of the other mounting surface from the insertion hole of the hanging metal fitting provided in the first bottom plate. It is an air conditioner that is screwed and fixed.
[0005]
The multi-surface fixture is an air conditioner formed in a convex shape, a rectangular tube shape, a U shape, an L shape, a prismatic shape, or a cylindrical shape.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
As described above, in the air conditioner of the present invention, at least two attachments in which insertion holes are formed at positions corresponding to the hanging brackets of the top plate and screw holes that are screwed into the respective surfaces from different directions are formed. A multi-surface fixture having a surface is provided, and a screw is inserted into a screw hole of one mounting surface of the multi-surface fixture by screwing from an insertion hole of the top plate, and the first hole is fixed to the screw hole of the other mounting surface. Since the screws are screwed in and fixed from the insertion holes of the hanging brackets provided on the bottom plate of the slab, the screws screwed from the top plate should be removed even when the air conditioner is placed with the top plate facing up The top plate can be removed.
