DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint for a pipe protection cover at a pipe connection on the outdoor unit side of an air conditioner.

[0002]

2. Description of the Related Art Conventionally, in this type of pipe cover, in a pipe at an exposed portion from an indoor unit to an outdoor unit, a wide variety of pipe protection covers are provided on the wall between the wall and the pipe connection portion of the outdoor unit. However, pipes and drain hoses are exposed from the lower end of the wall surface to the outdoor unit without protection, so that taping and construction are required. Further, there is no protective cover for the pipe connection portion of the outdoor unit, and the connection portion cover adapted to the existing pipe cover is difficult in terms of construction and cannot be reliably joined (Japanese Patent Laid-Open No. 62-165086).

[0003]

However, with the conventional pipe cover for pipes as described above, the pipe cover cannot be applied to the pipes from the lower end of the wall surface, and the heat insulating coating material and drain hose of the exposed pipes cannot be used. The deterioration of the material progresses due to the sun's ultraviolet rays, etc., and the heat insulation of the piping has a large effect on the deterioration of the performance of the air conditioner due to the poor heat insulation, and the drain hose has the durability due to the hardening of the material itself. There is a decrease
Maintenance was forced to improve.

In addition, it is important to have a function that can be easily installed in order to improve the quality of the house in recent years, the exterior property due to the fusion of the house, and the service construction performance of the air conditioner, and that a stable quality can be ensured. Is coming.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is to insert an exposed portion of a pipe covered by a pipe from the room along a wall surface from an opening of a connection cover for covering a pipe connection of an outdoor unit. A pipe connection joint cover that holds and protects pipes, and a pipe connection joint cover that is integrally provided with a bellows-type flexible part that inserts and holds a curved part of the pipe through the joint cover, and the lower surface of those pipe connection joint covers A knockout hole for insertion and extraction of a drain hose is provided on the side, which facilitates installation of piping and a piping cover such as a drain hose, and solves the problem of external problems caused directly by piping. .

[0006]

According to the present invention, the protective cover for the exposed portion of the pipe is protected by a synthetic resin-made pipe connection joint cover by the above method to maintain the weather resistance of the pipe and the drain hose from the sun's ultraviolet rays, Simplifies and improves installation and construction serviceability. Further, since it is made of a synthetic resin, it can be manufactured at low cost by improving the effects of mass productivity such as good workability.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a pipe joint cover according to an embodiment of the present invention. 1 and 2, a pipe connection portion 1a of an outdoor unit 1 of an air conditioner is covered with a connection portion cover 1b, and a pipe B connected between the pipe opening hole 1c and the indoor unit A , an indoor unit B To drain the dehumidifying water from A
Drain hose C and power supply line for power supply (Figure
The wall pipe cover (not shown) etc.
Composed of flexible parts 4 used according to
Minutes). On the other hand, wall pipe cover and outdoor
The connection pipe between the connection portions of the unit 1 has one end connected to the connection cover 1b and the other end connected to the pipe cover 2 and extended.
It is configured to be connected to the bellows-type flexible part 4.
The connection joint cover 3 protects
It is arranged like this .

As shown in FIGS. 3 and 4, the connection joint cover 3 has a connection port 3 that can be joined to the wall pipe cover 2.
c , and the opening 1 of the connection cover 1b of the outdoor unit
and a connection port 3d which can be bonded is c, during which molded gradually cylindrical shape which is bulging, the pipe directions separated vertically bisected connected upper cover 3a and a lower cover 3b was to the engagement connection The locking projection 3e and the engagement recess 3f are provided on the divided inner surface.

On the lower surface side, the drain hose C is provided.
Knock-out type , ie finger, etc.
Pressing with a knife or cutting with a cutter knife
So that it is possible to form a hole by punching
Is formed so as to have a surface configured to be connected to the main body side, so that a through hole can be easily formed, and a structure in which dehumidified water can be drained out of the connection joint cover 3 is obtained.

【The invention's effect】 As is apparent from the above description, the present inventionBy
IfThe air conditioner outdoor unit and indoor unit
Piping cover for protecting piping pipes that circulate conditioning refrigerant
And the pipe connection joint cover of the outdoor unit
By connecting, even if you are not a skilled installer,
Easy to install, high quality piping and pipe cover
Removal at the time of maintenance inspection is simple and leads to a reduction in man-hours. Ma
In addition, because it is made of synthetic resin, weather resistance such as sun's ultraviolet rays,
It is also effective for water tightness, so the performance of internal piping pipes etc.
Can be maintained, and the number of maintenance inspections can be reduced.Furthermore,Manufacture
It is relatively inexpensive because of its excellent mass productivity
ValueConstitutionit can.
