Description

[Detailed Description of the Invention] The present invention relates to an improvement in the mounting structure of an air conditioner used when the main body of the air conditioner is installed in the ceiling of a building, a so-called ceiling concealed air conditioner.

Conventionally, in this type of mounting structure, a support rod b is fixed in a hanging state to an auxiliary joist a in order to support an installation device suspended horizontally in the ceiling, as shown in FIGS. The support rod b is connected to the support part c fixed to the air conditioner main body i, and the air conditioner main body i
was installed. Therefore, in the conventional art, the supporting portion c always protrudes from the side wall surface of the main body i, which increases the external dimensions accordingly, which has the drawback of making packaging, transportation, etc. inconvenient.

In addition, in this type of conventional structure, the air outlet duct g and the air intake duct h of the main body i are located directly above the air outlet grille e and the air intake grille f, which are provided on the ceiling d toward the room. When installing the main body i, if the position of the hanging rod b shifts even slightly, the support part c
Not only is it difficult to connect to the main body of the air conditioner, but it is also impossible to ensure a horizontal level for smooth drainage of dehumidified drain water from the air conditioner body i, and it is necessary to carefully install the hanging rod b. The workability was poor.

The present invention eliminates the drawbacks of the conventional mounting structure described above, and although it has a relatively simple structure, it not only allows the size of the air conditioner body to be reduced, but also allows the suspension rod to be slightly misaligned. The air conditioner itself can be installed easily and securely.
In addition, the present invention provides a mounting structure for an air conditioner that can ensure levelness for smooth drainage of drain water, which is an important consideration when installing the air conditioner in the ceiling.

This mounting hanging bracket 11 is attached to the aforementioned mounting plate 9a by tightening the main fixing bolt 12 and fixing screws 13b that pass through a plurality of long holes 13a for angle adjustment provided in the mounting hanging bracket 11. It is being By tightening and loosening the fixing screws 13b, it becomes possible to adjust the levelness of the mounting plate 9a in the left-right direction (direction of arrow A in the figure). In addition, the above-mentioned hanging fitting 11 can be installed by tightening the fixing screws 15b into the plurality of elongated holes 15a for vertical adjustment provided in the main hanging fitting 14.
It is attached to the main hanging fitting 14. The main hanging fitting 14 is provided with a large number of holes 16 in a staggered manner.
This hole 16 allows adjustment of the approximate mounting position of the mounting plate 9a in the vertical direction.

Further, a plurality of nuts 17 are welded to a support piece 10d adjacent to the support pieces 10a and 10c at a predetermined height, and a bolt 18 that fits into the nuts 17 is inserted from the outside. . By tightening this bolt 18, the air conditioner main body 1 can be positioned in the front-rear direction (direction of arrow A in the figure), and the air conditioner main body 1 is fixed.

In addition, a heat insulating material 1 is attached to the remaining support piece 10b.

The t ₁ and the lateral dimension t ₂ are set slightly larger than the vertical dimension T _{1 and the lateral dimension T 2 of} the suction port 2 of the air conditioner main body 1 shown in FIGS. 3 and 4.

Next, the installation work of the air conditioner having the above structure and the installation device will be explained with reference to FIGS. 6 and 7.

In the figure, first, the outlet grill 28 and the suction grill 29 are attached to the ceiling 30 and the auxiliary joists 31, the sealing material 32 is pasted on the upper surface of the auxiliary joists 31, and the unit mounting plate 9a is placed on top of the sealing material 32. Next, the mounting hanging bracket 11 is fixed to the mounting plate 9a by tightening the main fixing bolt 12, and is attached to the auxiliary joist 33 for supporting the installation device horizontally suspended in the ceiling.
A main hanging fitting 14 having a large number of holes 16 arranged in a staggered manner is fixed in a hanging state. At this time, even if the height, position, etc. of the auxiliary joists 33 change, the best mounting position of the main hanging fitting 14 can be selected by the large number of holes 16 provided in the main hanging fitting 14.

Next, the main hanging fitting 14 and the mounting hanging fitting 11 are fixed with fixing screws 15b through a plurality of elongated holes 15a provided in the main hanging fitting 14. At this time, fine adjustments in the vertical direction of the unit mounting plate 9 can also be made using the elongated holes 15a.
Let's do it.

Then, the horizontality of the unit mounting plate 9a in the left-right direction (arrow A direction in the figure) can be adjusted by tightening the fixing screw 13b into the elongated hole 13a provided in the mounting hanging bracket 11.
Do this by relaxing.

Further, the air conditioner support fitting 20 is fixed to the unit mounting plate 9a with a plurality of bolts 24, and a blow-off duct 35 with a heat insulating material 34 affixed inside is installed.
are fixed to the auxiliary joists 31 and the air conditioner support fittings 20.

On the unit mounting plate 9a in the above state,
Two protrusions 2 are provided facing each other for left and right positioning of the air conditioner 1 (in the direction of arrow B in the figure).
The air conditioner main body 1 is placed so as to be located between the air conditioners 5 and 5. Then, the front and rear adjustment bolts 18 provided on the unit mounting plate 9a are tightened to fix the air conditioner main body. Here, the vertical dimension T ₁ and the horizontal dimension T ₂ of the suction port 2 of the air conditioner body 1 are set to be slightly smaller than the vertical dimension t ₁ and the horizontal dimension t ₂ of the suction hole 26 of the unit mounting plate 9a. Therefore, the air conditioner main body 1 can be easily adjusted in the front-back direction (arrow A direction) and the left-right direction (arrow B direction).

The above operations complete the installation of the air conditioner 1.

Therefore, before installation, the unit mounting plate 9a, mounting hanging bracket 11, main hanging bracket 14,
The air conditioner main body support fitting 20 and the blowout duct 35 are installed within the limited ceiling 30, and the air conditioner main body 1
Make sure that the mounting plate 9a is level so that the dehumidified drain water can be drained smoothly, and then
Since the air conditioner main body 1 can be placed on it,
This work is extremely easy to perform, maintenance and inspection work are also facilitated, and the outer shape of the air conditioner main body 1 can be made box-shaped to reduce its dimensions, making it easy to pack for transportation and the like. Furthermore, the vertical dimension t ₁ and the horizontal dimension t 2 of the suction hole 26 of the unit mounting plate 9a are the vertical dimension T 1 and _{the horizontal dimension T 2 of} the suction port 2 of the air conditioner body ₁ .
Since the air conditioner body 1 is slightly larger than the above, by moving the air conditioner body 1 slightly vertically or horizontally and adjusting it during installation, there will be no problem even if the position of the suction hole 26 and the suction port 2 are misaligned. I've never seen it happen.

In addition, since the blow-off duct 35 is attached to the air conditioner main body support 20 later, by changing the shape of the blow-off duct, not only the bottom blow, but also the side blow, the top blow and the unit mounting plate 9 can be left as they are. It can provide versatility.

As is clear from the above embodiments, the mounting structure of the ceiling-concealed air conditioner according to the present invention is to separately provide a mounting plate on which the air conditioner main body is placed, and to attach the mounting plate via the mounting plate hanging fittings. Since the air conditioner is supported by the main hanging bracket and placed on this mounting plate, the installation work of the air conditioner is easy, and the air conditioner can be formed into a box shape, making it easier to pack. Furthermore, since the mounting plate hanging bracket is attached to the main hanging bracket so that it can move up and down, and the mounting plate hanging bracket is attached to the mounting plate so that it can rotate, both of these functions can be achieved. The mounting plate can be supported horizontally, and leakage of condensed water caused by tilting the air conditioner can also be prevented. In addition, since the air conditioner mounted on the front and rear adjustment bolts can be moved in one direction and fixed, fine adjustments during installation are extremely easy. By making the vertical and horizontal dimensions larger than the vertical and horizontal dimensions of the suction port of the air conditioner, even if the suction hole and the suction port are misaligned due to movement adjustment of the air conditioner, problems such as leakage of suction air will not occur. In addition, since the air conditioner main body support bracket is attached to the mounting plate and the blow-out duct is attached to this, the duct mounting hole position is shared and the shape of the blow-off duct is changed, not only the bottom blow-out is possible. Versatility can be provided by leaving the side and top blowouts and unit mounting plate as they are, etc.
It has various advantages.
