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. It was covered with a material, and a tape was spirally wound around the heat insulating material to protect it.

[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 poor. Therefore, in order to protect the pipe covered with the heat insulating material without winding the tape around the heat insulating material, a cover made of a synthetic resin as shown in FIGS. 12 and 13 has recently been used. The cover includes a duct portion 3 covering a straight pipe portion 2 disposed along the outer wall surface 1 of the building, and a hood portion 6 covering a pipe outlet portion 5 from a hole 4 formed in the outer wall surface 1. And the duct portion 3 and the hood portion 6 are made separately. More specifically, the duct portion 3 includes a base portion 3a screwed to the outer wall surface 1 and a cover portion 3b engaged with the base portion 3a to form a cylindrical shape with the base portion 3a. The part 6 is also the outer wall 1
And a hood-shaped cover 6b engaged with the base 6a. Reference numeral 7 denotes an outdoor unit of an air conditioner.

[0004]

Therefore, in the above-mentioned conventional cover, since the duct portion 3 and the hood portion 6 are separately formed, there has been a problem that the cost is high. When it is desired to bend the pipe taken out of the hole 4 of the outer wall 1 of the building at an angle into, for example, an L-shape, a joint of, for example, another L-shaped member is interposed between the duct portion 3 and the hood portion 6. However, the bending angle of the piping differs depending on the installation condition of the air conditioner, etc., and there is a problem that it is necessary to prepare multiple types of joints with different bending angles so that it can respond even if the bending angle is different. As a result, there is a problem that the cost is increased.

The present invention solves such a problem, and is inexpensive as compared with the above-mentioned conventional synthetic resin cover, and can be freely operated even if the bending angle of the pipe taken out from the hole in the outer wall of the building changes. It is an object of the present invention to provide a cover for protecting an air conditioner pipe which can be used.

[0006]
