Pipe connecting device for air conditioning facility

The present invention relates to a pipe coupling device for an air conditioner, and more particularly, to a pipe coupling device mounted on the wall to facilitate the operation of connecting the pipes and wires to the outdoor unit and the indoor unit.

In general, air conditioners are widely used regardless of household or business use. The air conditioner is cooled to maintain the indoor temperature comfortably, and consists of an indoor unit and an outdoor unit for maintaining the quietness of the room and for heat exchange.

In this way, the refrigerant is circulated along the refrigerant pipe for heat exchange between the indoor unit and the outdoor unit. Such a refrigerant pipe is installed through the wall of the building. The operation of allowing the refrigerant pipe to penetrate the wall is not only cumbersome, but also hinders the aesthetics, and when the air conditioner is removed, a hole penetrating the wall is exposed to hinder the aesthetics.

In order to solve such a problem, there is a "coupling apparatus for air conditioning equipment (Patent Registration No. 10-0780381), which has been filed in advance. The pipe coupling apparatus of the air conditioning equipment shown in FIG. The pipe joint is erected and fixed in a box body in which one side of a length corresponding to the thickness of the pipe is opened, and the high pressure pipe and the low pressure pipe of the refrigerant pipe are respectively connected to at least an outdoor terminal of the pipe joint embedded in the box body, The pipe joint is connected to the high pressure pipe and the low pressure pipe from the indoor unit so that the corresponding high pressure pipe and the low pressure pipe are connected to the indoor terminal of the pipe joint. The pair of male connectors coupled to the ends of the tube, the corresponding high pressure tube and the corresponding low pressure tube, respectively, and the pair of female connectors incorporating the male coupler are the pair of plates. It is configured to be integrally connected by being engaged between the upper assembly.

The construction of the "pipe coupling device (patent registration No. 10-0780381) of the air conditioning equipment according to the configuration as described above is first buried the box body on the wall.

And the coupling plate of the pipe joint is fixed to the inside of the rear of the box body 100 by a fastening member. Subsequently, the elbow portion 231 penetrating through the locking hole formed in the joining plate material is aligned with the receiving hole 103 of the box body 100 through an opening on the upper side of the receiving hole 103 of the box body 100. Arrange.

At this time, the connector that is the body of the elbow portion 231 is to be fixed to each of the locking holes by the flange portion 310 of the male connector. In addition, after the O-ring (O) as a sealing material is inserted into the male connector, the female connector 250 is integrated with the male connector separately.

Next, after contacting the coupling plate member so that the flange 310 of the female connector 250, which is incorporated with the male connector, is fixed by the locking hole of the coupling plate member, the coupling member is contacted with each other via the fastening member. The pipe connection is finished.

And the female connector 250 using a known female thread-equipped piping socket in which the corresponding high pressure pipe and the corresponding low pressure pipe from the indoor unit are well-known, that is, the high pressure pipe and the corresponding low pressure pipe are expanded and fixed to the female connector. If the fastening and fixing to the male screw portion (m1) of the secondary indoor unit piping is also completed.

However, since the process of coupling the refrigerant pipe connected to the outdoor unit and the connector and the refrigerant pipe of the indoor unit to the coupled connector is performed inside the box body embedded in the wall, the process of connecting the refrigerant pipe is complicated and the work efficiency is reduced. There is a problem.

In addition, since the refrigerant pipe is connected in a narrow space, an excessive force is applied, and there is a problem that leakage occurs at the connection portion due to the excessive force.

Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to provide a pipe coupling device of an air conditioner that can easily connect the refrigerant pipe of the outdoor unit and the refrigerant pipe of the indoor unit.

The above object is achieved by the present invention, according to one aspect of the present invention, the pipe coupling device of the air conditioner, the front of the box shape is open, a pair of refrigerant pipe, water pipe and the inlet hole through which the wire is formed A case embedded in the wall; A plate-shaped plate formed with a pair of refrigerant fixing holes on which the refrigerant connector for connecting the refrigerant pipes is seated, and a water pipe fixing hole for mounting the water pipe connectors for connecting the water pipes, and a plate-shaped fixing plate mounted on the front of the case; ; Flexibility is maintained, one end of which is connected to the refrigerant pipe introduced into the case and the other end of the refrigerant flexible pipe connected to the refrigerant connector; And flexibility is maintained, one end of which is connected to a water pipe introduced into the case and the other end of the water pipe flexible pipe connected to the water pipe connector to connect the refrigerant pipe of the outdoor unit and the indoor unit to each other, wherein the refrigerant fixing hole And the water pipe fixing hole are each formed in a semicircular shape in the fixing plate so that the refrigerant connector and the water pipe connector are inserted into the open side portions of the refrigerant fixing hole and the water pipe fixing hole, respectively, and the heat insulating material and the finishing material on the front of the case. A plurality of thickness control plate for adjusting the height according to the thickness of the laminated, characterized in that the front cover of the thickness control plate is mounted.
