Description

[Detailed description of the invention] [Purpose of the invention] The present invention relates to a storage device for refrigerant piping used when the refrigerant piping that connects the indoor unit and outdoor unit of an air conditioner is housed within the wall of a building. It is. In existing houses, refrigerant pipes are generally passed through holes in the walls, but in newly built houses, refrigerant pipes and drain pipes are embedded in the walls during construction of the building. By the way, the embedding of refrigerant piping and drainage pipes needs to be done at the same time as the construction work, so the piping work is subject to timing constraints, and construction progress is inconveniently halted until the piping work is completed. . In addition, if defects in piping work are discovered or inspections become necessary after construction work is completed, the building must be demolished and repaired and inspected. The object of the present invention is to provide a storage device for refrigerant pipes and drain pipes that is free from the above-mentioned inconveniences and inconveniences.

[Structure of the idea]

The present invention consists of a piping duct with a U-shaped cross section that has a pair of protruding edges for regulating the positions of refrigerant piping and drain pipe, and a piping duct that fits into the open part on the front of the piping duct.
An air conditioner comprising a duct cover having a pair of protrusions and a bottom plate having a dish-shaped extension, wherein the piping duct is housed in a space formed between an outer wall and an inner wall of a building. This is a refrigerant pipe storage device.

Embodiments of the present invention will be described with reference to the drawings. 1st
In the figures, 1 is the main pillar of the building, and 2 is a stud provided between the main pillars. 3
Reference characters a and 3b are rims fixed to the main pillars 1 and studs 2 at a slight interval in parallel with the floor surface, and form the framework of the outer wall 4 and the inner wall 5. Outer wall 4 and inner wall 5
An exterior and an interior (not shown) are provided on the surface. The above is the structure of the wall of a general house, and the storage device of the present invention is installed in the space formed between the outer wall 4 and the inner wall 5.

The storage device of the present invention includes a refrigerant pipe 6 and a drain pipe 7.
a piping duct 8 with a U-shaped cross section that accommodates the piping duct 8; a duct cover 9 that covers the open part on the front of the piping duct 8; and a duct cover 9 that covers the open part at the lower end of the piping duct 8 that forms the outlet of the refrigerant pipe 6 and the drain pipe 7. It consists of a bottom plate 10. The piping duct 8 has a pair of protrusions 8a and 8b that regulate and hold the positions of the refrigerant pipe 6 and the drain pipe 7, and the duct cover 9 has a pair of protrusions that fit into the open part on the front of the piping duct 8. 9a and 9b, and the bottom plate 10 is provided with a dish-shaped extension 10a for drawing out the refrigerant pipe 6 and the drain pipe 7.

Next, installation of the storage device of the present invention will be explained. The indoor side rim (inner rim) 3b is cut to match the width of the piping duct 8, supports 2a and 2b are provided on both sides, the piping duct 8 is fitted between the supports 2a and 2b, and the interior is closed using screws 11. Outer rim (outer rim) 3
Fix it to a. 12 is the outer rim 3a and the piping duct 8
The position of the piping duct 8 is regulated by a spacer interposed between. Then, after inserting the refrigerant pipe 6 and the drain pipe 7 by pushing them against the elastic force of the projecting sides 8a and 8b, fit the duct cover 9, and screw the screw 13.
It is fixed to the inner barrel rim 3b by. The thickness of the spacer 12 is set so that the surface of the fixed duct cover 9 continuously matches the surface of the inner wall 5. Further, the screw 13 is a recessed type so that its head does not stick out. In FIG. 3, 14 is the foundation of the building, 15 is the base, 16 is the joist, and 17 is the floorboard. The saucer-shaped extension 10a of the bottom plate 10 projects below the floorboard 17 from the missing part of the joist 16.

[Effect of idea]

Since the present invention has the above configuration, it has the following effects. (1) Since the piping duct 8 is installed by a construction worker, the piping work is not related to the progress of the construction work, and after the installation of the piping duct 8 is completed, the piping work can be carried out at any time by the plumber. There are no problems between construction and construction work. (2) If inspection or repair is required after the piping is completed, the refrigerant piping 6 and the drain pipe 7 can be easily pulled out by removing the duct cover 9, and there is no need to destroy part of the building. (3) Since the refrigerant pipe 6 and the drain pipe 7 are housed in the pipe duct 8, they are safely protected. In addition, when condensation water occurs on the surface of the refrigerant piping or water leaks from the drain pipe, there is no possibility that the water will seep into the pillars or walls and cause corrosion.
