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 portion of an outdoor unit of an air conditioner.

[0002]

2. Description of the Related Art Conventionally, a pipe cover of this type is protected and constructed by a wide variety of pipe covers between a wall surface and a pipe connection portion of the outdoor unit from the indoor unit to the outdoor unit. However, since the pipes, drain hoses, and the like are exposed without being protected from the lower end of the pipe cover on the wall surface to the pipe connection part of the outdoor unit, taping is only required. In addition, there is no protective cover for the pipe connection portion of the outdoor unit, and the existing pipe cover is difficult in terms of service construction and cannot perform a reliable joining work. Also, since the pipe mounting pitch of the pipe connection portion of the outdoor unit is large, the pipe pipes are concentrated to the pipe cover, and there is no curved pipe cover member, so that protection of the pipe pipes and drain hoses is insufficient. (JP-A-62-165086).

[0003]

However, with the conventional pipe cover for pipes as described above, a sufficient protection cover cannot be applied to the pipe pipes from the lower end of the wall, and the heat insulating covering material of the exposed pipe pipes cannot be provided. Deterioration of drain pipes and drain hoses due to the sun's ultraviolet rays, etc., deteriorates the insulation of pipes and pipes, which has a major effect on the performance of air conditioners. The durability of the steel was reduced due to the hardening of the steel.

In addition, in recent years, it has become important to have a function that can be easily installed in terms of the high quality of the house, the exterior property due to the house fusion, the service construction performance of the air conditioner, and the ability to secure stable quality. Is coming.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a piping pipe between a pipe connection portion of an outdoor unit and an opening of a power supply cover for covering a power supply portion, from a room to a pipe cover along a wall surface. A joint joint cover with a stepped bellows-type flexible pipe that penetrates and exposes the exposed part of the pipe and protects the pipe by connecting and covering the pipe with the joint cover according to the curve of the pipe. And open the outdoor unit side of those connection joint covers, and provide a knockout hole to draw out the drain hose from the open side to the lower surface, and have a U-shaped cross-section and work as a protective cover for piping pipes and drain pipes such as drain hoses Piping from the piping connection of the outdoor unit to the piping cover when connecting Can skip set routing work, joint work of the connection joint can be a simplified, and mitigate the effects and problems from the outside due directly against pipes such as pipes, is obtained by resolution.

[0006]

According to the present invention, the exposed pipe is protected by a joint joint cover made of synthetic resin by the above-mentioned method, and the weather resistance of the pipe and the drain hose from the sun's ultraviolet rays is maintained. Installation and construction serviceability are simplified and improved.

Further, since it is made of a synthetic resin, it is possible to reduce the cost by improving the effect of mass productivity such as good workability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A connection joint cover for a pipe according to an embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1 and FIG. 2, the pipe connection portion 1a of the outdoor unit 1 of the air conditioner is covered by a power supply cover 1b, and a connection is made from the power supply cover to the indoor unit A through an opening 1c having a high mounting pitch. The pipe is connected to a pipe pipe B to be connected and held, and is collected and housed in a pipe cover 2 for protecting and protecting the wall side. A drain hose C for draining dehumidified water from the indoor unit A is accommodated in the pipe cover 2, and a pipe B between the wall surface side and the outdoor unit 1 and the drain hose C are inserted through the pipe cover 2 and held. And a connection joint cover 3 capable of engaging the power supply cover 1b of the outdoor unit 1, a large-diameter portion 4a having an opening height to be drawn out from the pipe B, and a small-diameter portion approximately matching the outer diameter shape of the pipe cover 2. The port 4c and the end 4d which is inscribed in the pipe cover 2 are formed, and the middle portion between the large-diameter portion 4a and the small-diameter portion 4c is tapered to integrally form a tapered portion 4b for gathering the pipe 2 in a stepped state. Meanwhile, the exposed curved portion of the pipe pipe 2 is inserted and held by the bellows-type flexible pipe 4 so as to be connected, so that the pipe pipe B and the drain hose C are protected from the outside. It is disposed.

As shown in FIGS. 3 and 4, a connection joint cover 3 is connected to a connection port 3c through which a pipe cover 2 from a wall surface can be joined to an opening hole 1 of a power supply cover 1b of the outdoor unit.
In accordance with the shape of each of the connection ports 3d to be joined in a soldering state with c, the connection ports 3d are bulged, the side in contact with the outdoor unit 1 is opened, and a cylindrical shape is formed with a U-shaped cross section.

Further, by forming a drain outlet 3b through which the drain hose C is inserted from the open side to the lower surface in a knock-out manner, the drain outlet C can be easily removed, the drain hose C can be pulled out, and dehumidified water can be removed from the connection joint cover 3 outside. Drainage structure.

The power supply cover 1b of the outdoor unit 1 and the pipe cover 2 from the indoor wall are formed by integrally forming the stepped bellows type flexible pipe 4 on the connection joint cover 3 and the connecting cover 3b. Is provided with a connection port 3a connected in a bidirectional manner in a bidirectional manner, and a connection port 4d of the pipe cover 2 provided in the small-diameter portion 4c of the flexible pipe.

[0013]

As is clear from the above description, the present invention
A connection joint cover is connected to a power supply cover of the outdoor unit, to a protection pipe cover of a pipe for circulating an air conditioning refrigerant between the outdoor unit and the indoor unit of the air conditioner. In addition, the stepped flexible pipe facilitates the collective routing work of the exposed piping pipes from the outdoor unit to the piping cover and the insertion work of the curved portion,
Easy installation and service work by non-skilled installers, high-quality piping and piping cover installation, easy removal during maintenance and inspection, and reduced man-hours.

Further, since it is made of synthetic resin, it is effective for weather resistance against ultraviolet rays of the sun and the like and watertightness, so that the performance of the internal piping and the like can be maintained, and the number of maintenance and inspection is reduced. Because of its excellent mass production in terms of molding process during manufacturing,
Can be relatively inexpensive.
