Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a piping fixing device for an air conditioner (hereinafter referred to as an air conditioner).

Conventional technology In recent years, as air conditioners have become more diverse in terms of the rooms to be air-conditioned, their capabilities have become more segmented, and the pipe diameters have also become more diverse, from thin to thick. A variety of things are used. A conventional air conditioner piping fixing structure will be described with reference to FIGS. 4 to 6.

1 is the outer frame of the box-shaped iron plate air conditioner body, 2 is the heat exchanger (not shown) inside the air conditioner body,
In the extended refrigerant pipe, 3 is a cylindrical heat insulating material made of foamed polyethylene or the like to prevent heat exchange between the pipe 2 and the outside air. Reference numeral 9 denotes a hole drilled in the outer frame 1, the diameter of the upper semicircle is the same as the outer diameter of the heat insulating material 3, and the diameter of the lower semicircle is one size larger than that. The shape of the hole 9 is designed to facilitate passage of the pipe 2 during assembly of the air conditioner and to maintain airtightness after fixation. 1
0 is a fixture for fixing piping; a notch 11 consisting of a semicircle and a straight part having the same diameter as the outer diameter of the heat insulating material 3; and a round hole 12 through which the screw 8 for attaching the fixture 10 passes.
is open.

The pipe 2 with the heat insulating material 3 extending outside from the hole 9 is pushed upward by a fixture 10 and fixed by a screw 8 for attaching the fixture 10.

Problems to be Solved by the Invention However, with the above configuration, the diameters of the upper semicircle of the hole 9 and the semicircle of the notch 11 must be changed every time the pipe diameter changes, and the shape of the hole 9 must be changed. Because of the complexity, the productivity of parts and the workability of passing the piping 2 through it were also poor.

In view of the above-mentioned drawbacks, the present invention provides a pipe fixing device that allows the pipe to be fixed with the same member even if the pipe diameter changes and has good workability for passing the pipe.

Means for Solving the Problems In order to solve the above problems, the air conditioner piping fixing device of the present invention includes a pipe, an insulating material around the pipe, and a diameter that is one size larger than the outer diameter of the insulating material. It consists of an outer frame of the air conditioner with a round hole and two fixtures that sandwich the pipes facing each other. It has holes.

Effects In the present invention, as in the above configuration, the outer frame of the air conditioner is provided with a round hole having a diameter one size larger than the outer diameter of the heat insulating material, thereby improving the workability of passing the piping. Also,
Since the notch of the fixture is approximately semi-circular,
Even if the pipe diameter changes somewhat, airtightness can be maintained by sandwiching it between two opposing fixtures. In addition, since the hole for attaching the fixture is a long hole, it can be fixed flexibly after being sandwiched.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. Note that the same numbers are used for the same parts as in the conventional example. 1 and 2 show the main parts of the piping fixing structure of the air conditioner, and FIG. 3 shows the entire air conditioner.
1 is the outer frame of the box-shaped iron plate air conditioner main body, 2 is a pipe extending from the heat exchanger (not shown) inside the air conditioner main body, and 3 is a heat exchanger between the pipe 2 and the outside air. It is a cylindrical heat insulating material made of foamed polyethylene or the like to prevent the heat insulating material 3 from occurring, and 4 is a round hole drilled in the outer frame 1, the diameter of which is one size larger than the outer diameter of the heat insulating material 3. The diameter of this hole is made slightly larger to make it easier to pass the pipe through when assembling the air conditioner. Reference numeral 5 denotes a fixture for fixing piping, which has a substantially semicircular notch 6 with its opening widened and a long hole 7 through which a screw 8 for attaching the fixture 5 passes. Further, 2' is a pipe having a smaller diameter than arrangement 2, and 3' is a heat insulating material for the pipe 2'. A method of fixing the piping in the device as described above will be explained. The pipe 2 with the heat insulating material 3 extending outside from the round hole 4 is pressed down from above and below by a fixture 5, and fixed through the elongated hole 7 with a screw 8. Further, when the pipe 2 has a small diameter, as shown in FIG. 2, a large amount of pressing space is provided for the fixture 5, and the pipe 2 is similarly pressed from above and below by the fixture 5, and fixed with screws 8. At this time, since the pipe 2 has a small diameter, a roughly triangular gap tends to occur on the left and right sides of the pipe 2, but the cutting material 3' is often made of an elastic material such as foamed polyethylene, and By increasing the pressing allowance of the tool 5, the above problem can be eliminated. Therefore, even if the diameter of the pipe changes, the pipe can be fixed with the same member, and the hole through which the pipe passes is also a round hole, which improves the productivity of parts and the workability when assembling the air conditioner.

Effects of the Invention As is clear from the above explanation, the air conditioner piping fixing device of the present invention has a round hole that is one size larger than the diameter of the piping insulation material in the outer frame of the air conditioner, and the piping is inserted through the round hole. After the pipe has passed through, it has a semi-circular notch and a long hole, and is fixed with two opposing fixtures, so even if the pipe diameter changes, the Since there is no need to change the size of the hole and the shape of the hole is round, it is effective in improving the productivity of parts and the workability when assembling the air conditioner.
