DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover for covering a refrigerant pipe connecting an indoor unit and an outdoor unit of an air conditioner.

[0002]

2. Description of the Related Art Conventionally, copper pipes are used as refrigerant pipes connecting an indoor unit and an outdoor unit of an air conditioner. For protection of heat insulation, the pipes are insulated except for an end for connection with the outdoor unit. In addition, the tape was spirally wound around the heat insulating material while being covered with the material.

[0003]

However, there is a problem that the work of spirally winding the tape around the heat insulating material is very troublesome and the work efficiency is low.

An object of the present invention is to solve such a problem, and an object of the present invention is to provide an air-conditioner pipe protection covering capable of greatly improving workability as compared with a case where a tape is spirally wound. Is what you do.

[0005]

SUMMARY OF THE INVENTION In order to solve this problem, the present invention relates to a refrigerant pipe which connects an indoor unit and an outdoor unit of an air conditioner and is covered with a heat insulating material for heat insulation protection. An air-conditioning pipe protection covering that covers from the outside,
The gist is that the tube is made of a synthetic resin tube having flexibility and elasticity, and is rounded so as to have a ring shape with a multi-layered cross section before being attached to a heat insulating material outside the pipe. Further, the present invention is an air conditioner pipe protection covering body that connects an indoor unit and an outdoor unit of an air conditioner and covers a refrigerant pipe covered with a heat insulating material for heat insulation protection from outside the heat insulating material. The gist is that it is made of a fabric made of a synthetic fiber having a property and has a cylindrical shape, and is rounded so as to have a multi-layered ring shape before being attached to the heat insulating material on the outside of the pipe. .

[0006]

The use of the air-conditioner pipe protecting cover having the above-mentioned structure makes it possible to greatly improve workability as compared with the conventional example in which a tape is spirally wound around a heat insulating material. Moreover, since the coating is rounded in a ring shape having a multi-layered cross section before use, it is not bulky and is very convenient for storage and carrying.

[0007]

An embodiment of the present invention will be described below with reference to the drawings. 1 to 6, reference numeral 1 denotes a wall 2 in the room.
An indoor unit 3 of an air conditioner mounted on the upper part of the air conditioner is an outdoor unit of an air conditioner installed outdoors. The indoor unit 1 and the outdoor unit 3 have two pipes for an outward path and a return path so that refrigerant can reciprocate. They are connected by four. Copper pipes are used for the refrigerant pipes 4, and each pipe 4 is covered with a heat insulating material 5 made of styrene foam except for an end for connection with the outdoor unit 3 for heat protection. I have. The two pipes 4,
Numeral 4 is housed in one synthetic resin duct 6 and arranged vertically along the wall so that the portion along the wall of the building is collected as one bundle, and connected to the outdoor unit 3 from the wall. It has a bifurcated shape up to the use end. Reference numeral 7 denotes a covering made of a synthetic resin tube according to the embodiment of the present invention, which covers the heat insulating material 5 on the outside of each of the bifurcated pipes 4 from the wall surface to the vicinity of the end for connection with the outdoor unit 3. It has become. Specifically, the tube forming the cover 7 is made of, for example, soft vinyl chloride or a thermoplastic elastomer and has flexibility and elasticity, and is formed so that the inner diameter is slightly smaller than the outer diameter of the heat insulating material 5. When installing the air conditioner, connect each pipe 4 to the outdoor unit 3
To cover the pipe 4 from outside of the heat insulating material 5 before connecting it.
By the way, before use, the coating 7 is rounded so that the cross section becomes a ring shape with multiple layers as shown in FIG.
In this state, the cover 7 is externally fitted to the end of the connection with the outdoor unit 3 and positioned at the end of the heat insulating material 5, and the cover 7 rolled into a ring shape is developed into a tubular shape. It covers the heat insulating material 5 outside each of the pipes 4 in the shape of a circle. The ring-shaped cover 7 is shown in FIG.
5 and 6, the guide member 8 is applied to the end of the heat insulating material 5 at the time of mounting on the heat insulating material 5 outside the pipe 4 shown in FIGS. Thus, the cover 7 can be easily mounted on the heat insulating material 5.

In the above embodiment, the heat insulating material 5 on the outside of each of the forked pipes 4 is covered by the covering 7, but the two pipes 4 and 4 along the wall of the building are formed as one bundle. Instead of the duct 6 to be combined, it is also possible to combine the two pipes 4 and 4 as one bundle by using a coating having a larger diameter than that of the embodiment.

The coating 7 of the first embodiment described above is formed of a synthetic resin tube. For example, a stretchable synthetic fiber such as polyurethane (spandex) is combined with another synthetic fiber. It is also possible to form a fabric (fabric) knitted into a tubular shape by knitting using a material and processed to have elasticity, weather resistance, abrasion resistance, and water repellency. Before being mounted on the outer heat insulating material, the cross section may be rounded so as to form a ring having multiple layers and may be attached to the guide member as in the first embodiment.

[0010]

As described above, the use of the air-conditioner pipe protection covering of the present invention makes it possible to greatly improve the workability as compared with the conventional example in which a tape is spirally wound around a heat insulating material. it can. Moreover, since the coating is rounded in a ring shape having a multi-layered cross section before use, it is not bulky and is very convenient for storage and carrying.
