[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe fixing device of an air conditioner having a pipe bending function.

[0002]

2. Description of the Related Art Generally, when an indoor unit as an air conditioner is installed, it is necessary to bend a pipe in a casing to the outside and draw it out to connect it to a pipe from the outdoor unit. Conventionally, in this work, at the installation site, after removing the fixture from the pipe fixed with the fixture to the casing, pull out while bending so that the pipe is not flattened, and fix the pipe again with the fixture, This is performed by connecting this piping with piping from the outdoor unit.

[0003]

However, in the conventional method using the above-mentioned fixing device, it is necessary to remove and re-install the fixing device at the installation site, and to perform a work for bending the pipe so as not to be flattened. Requires skill. In addition, it is necessary to increase the piping space for the complicated work of removing and re-attaching the fixture and bending the piping, so that there is a problem that the installation space is also increased.

Accordingly, an object of the present invention is to provide a piping fixture for an air conditioner that does not require removal and reattachment of the fixture, and can easily and reliably bend the pipe in a small space. .

[0005]

In order to achieve the above object, the pipe fixing device of the air conditioner of the present invention is mounted on a casing 10 of the air conditioner as shown in FIG. Fixing part 1 for fixing pipe to casing 10
2a and a pipe 11 on both sides of the opening of the pipe fixing portion 12a.
Pipe bending portions 12b, 12b that are curved and continuous in the bending direction
Are integrally provided.

[0006]

According to the pipe fixing device of the present invention, when the pipe 11 is bent, the fixing device 12 is not removed without removing the pipe 11.
Is bent while being applied to one of the pipe bending parts 12b, 12b connected to both sides of the opening of the pipe fixing part 12a of the fixture 12, the pipe 11 is bent by the pipe bending part 12b serving as a jig.
Can be bent so that it is not flattened. Thereby, the work of removing and reattaching the fixture 12 becomes unnecessary, and the workability is improved. In addition, since the pipe 11 can be easily and reliably bent to either side of the above-mentioned opening even if it is not a skilled person, the workability is also improved from this point and it is convenient. Furthermore, since the work of removing and reattaching the fixture 12 is not required, and the work of bending the piping can be easily performed, the piping space may be narrow and the installation space may be narrow.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the illustrated embodiments. As shown in FIG. 1, a pipe 11 for connecting a pipe from an outdoor unit is fixed in a casing 10 of an indoor unit of the air conditioner with a fixture 12.

The fixture 12 integrally has a pipe fixing part 12a having a rectangular cross section for fixing the pipe 11 to the casing 10, and a pipe bending part 12b described later. The fixing device 12 may be formed by stamping a panel of the casing 10 with a press, or may be formed by fixing a member having a rectangular cross section of another part to the panel of the casing 10 with a screw or the like.

In the indoor unit manufacturing factory, the pipe 11 is
As shown by the solid line, the casing 10 is fixed by a fixture 12 so as to be parallel to the longitudinal direction of the casing 10. Then, at the installation site, as shown by a two-dot chain line, it is drawn out while being bent, for example, rightward to the outside of the casing 10 and connected to a pipe from an outdoor unit.

The fixture 12 is provided integrally with pipe bending portions 12b, 12b which are curved and continuous in the bending direction of the pipe 11 on both sides of the opening of the pipe fixing portion 12a. The curvature of the pipe bending portion 12b is appropriately set according to the diameter, bending angle, and the like of the pipe 11. This pipe bending part 12
b can also be easily formed simultaneously by pressing.

With the above configuration, the piping 11 can be installed at the installation site.
To perform the bending operation, do not remove the fixture 12,
When the pipe 11 is bent by hand or the like while applying the pipe 11 to the pipe bending part 12b of the fixture 12, the pipe bending part 12b becomes a jig, and the pipe 11 is guided by the pipe bending part 12b to apply a large bending force. Even so, the pipe can be bent so as not to be flattened. Therefore, compared to the case where the pipe is bent with the fixture of the conventional example without the pipe bending portion 12b attached,
The pipe 11 can be bent at a large angle, the projecting dimension of the pipe 11 becomes long, the connection work of the pipe becomes easy, and the pipe 11 can be bent in either the left or right direction of the opening of the pipe fixing portion 12a, which is convenient.

As a result, the pipe 11 can be bent easily and surely even by a non-expert, and the work of removing and reattaching the fixture 12 as in the prior art is not required. improves. In addition, since there is no need to remove and reattach the fixture 12, and to easily perform the bending operation of the pipe 11, the piping space may be small, and the installation space of the indoor unit can be reduced.

In the above embodiment, the pipe fixture 12 has a rectangular cross section, but may have a semicircular cross section (U-shaped pipe).

In FIG. 1, the base of the L-shaped pipe 11 is provided with pipe bent parts 12b and 12b on both sides of a pipe fixing part 12a.
Since it is fixed by the fixture 12 having b, the length of the arm of the bending moment becomes longer, and the pipe 11 can be bent with a smaller force. Also, the protrusion dimension W becomes longer,
Workability is improved. The piping fixture of the present invention is shown in FIG.
Not limited to the position and direction shown in FIG.

[0015]

As is apparent from the above description, the pipe fixing device of the air conditioner of the present invention is provided with the pipe bending direction on both sides of the opening of the pipe fixing portion attached to the casing to fix the pipe to the casing. Since the pipe is bent integrally with the bent pipe, the pipe can be bent so as not to be flattened by bending the pipe while applying the pipe to the pipe bent section. Therefore, it is not necessary to remove and reattach the fixing device as in the prior art, and the pipe can be easily and surely bent at a large angle and to either side of the above-mentioned opening even if it is not a skilled person. The workability and convenience of bending and connection are improved. In addition, since there is no need to remove and re-attach the fixture and to easily perform the bending work of the piping, the piping space may be narrow and the installation space may be reduced.
