The second connection member 434 has a second hollow 431a is formed so that the flexible tube 211 is inserted, it is screwed with the other side of the first connection member 432.

The first sealing member 433 may be a ring such as one or a plurality of O-rings.

The first sealing member 433 is installed to be fitted to the outer circumference of the flexible tube 211, and an outer surface thereof is an outer circumferential surface of the flexible tube 211 and a first hollow 432a of the first connecting member 432. It adheres to the inner surface.

The first elastic member 466 is installed to be fitted to the outer circumference of the flexible tube 211.

One end of the first elastic member 466 is supported on one surface of the first sealing member 433, and the other end thereof is supported on a peripheral region of the second hollow 434a of the second connecting member 434. .

On the other hand, a positioning member 435 is further disposed between the fixing member 431 and the first sealing member 433.

The positioning member 435 may be a washer that is fitted to the outer circumference of the flexible tube 211, and one side thereof is fitted to the fixing member 431 to be fixed to determine the position of the fixing member 431.

One end of the first discharge line 210 and the second discharge line 220 is fixed to the faucet body 410, and a cover 420 that is rotatable open and closed is installed.

The wall 30 further includes buried pipes 450 to which the first discharge line 210 and the second discharge line 220 are inserted and covered.

2, one end of each of the first discharge line 210 and the second discharge line 220 is connected to a water discharger.

The water ejector may be a toilet 50, a sink 60, and a faucet 70 as illustrated in FIGS. 3 to 5.

The third opening and closing valve 330 is installed on the first discharge line 210 between the faucet body 410 and the water discharger, and the fourth opening and closing valve 340 is the faucet body. It is preferable to be provided on the second discharge line 220 between the 410 and the water discharge.

In addition, the first discharge line 210 and the second discharge line 220 may be provided in plurality, spaced apart from each other by a predetermined distance, and may be arranged in parallel with each other.

In addition, buried pipes 450 may be further installed on the wall 30 to cover the first discharge line 210 and the second discharge line 220.

In addition, a distribution unit 700 having a distribution line 710 branched from the hot water line 110 and the cold water line 120 and connected to each other between the water discharge parts 200 may be installed. The distribution unit 700 is installed in the form of a kind of faucet box, the user can be installed selectively.

Next, to explain the operation of the water supply system of the present invention configured as described above.

Referring to FIG. 1, the supply source 10 supplies a predetermined amount of water to the hot water line 110 and the cold water line 120.

The water is introduced into the boiler 20, the boiler 20 flows hot water above a predetermined temperature to the hot water line 110 and cold water below a certain temperature to the cold water line 120.

Subsequently, the hot water is discharged from the water discharge part 200 through the first discharge line 210, and the cold water is discharged along the second discharge line 220.

In this case, referring to FIG. 3, the hot and cold water discharged through the first and second discharge lines 210 and 220 flow toward the faucet body 410 embedded in the wall 30.

As such, the hot and cold water flowing to the first and second discharge lines 210 and 220 may flow to the sink 60 side.

In this case, the flow of water in the first discharge line 210 and the second discharge line 220 may be controlled by opening and closing the first opening / closing valve 310 and the second opening / closing valve 320.

Therefore, the water may be discharged as described above from the plurality of water discharge units 200.

If an abnormality occurs in any one of the plurality of water discharge parts 200, the first open / close valve 310 or the second open / close valve 320 may be blocked.

On the other hand, with reference to Figures 2 to 5, it will be described with respect to the circular receiving box 400 installed in the cross section of the wall (30).

The faucet body 410 of the circular faucet 400 is buried in one surface of the wall (30). At this time, the inside of the faucet box body 410 may be exposed to the outside.

Each of the faucet body 410 is provided with a coupling portion 430 is coupled to the buried pipe 450.

As mentioned above, the first discharge line 210 or the second discharge line 220 is inserted into the buried pipe 450.

In addition, a rotary cover 420 is installed on the faucet body 410. The rotary cover 420 has a hole (not shown) is formed so that the first discharge line 210 or the second discharge line 220 extends to the outside.

If the first discharge line 210 or the second discharge line 220 is to be replaced, the first opening / closing valve 310 or the second opening / closing valve 320 is closed and exposed to the outside of the wall 30. The third or fourth opening / closing valves 330 and 340 may be closed, and the rotary cover 420 may be separated from the receiving box body 410.

For example, when the first opening / closing valve 310 is blocked, hot water is not supplied to the first discharge line 210. On the other hand, hot water is supplied to another first discharge line 210 of the other water discharge unit 200.

Therefore, the flow of hot and cold water to the first and second discharge lines 210 and 220 may be selectively blocked.

At this time, the hot and cold water to the other water discharge unit 200 can be easily supplied by the distribution line 710 of the distribution unit 700 as shown in FIG.

Therefore, it is possible to isolate only the water discharge unit 200 in which an abnormality occurs and to perform maintenance without affecting the other water discharge unit 200.

Subsequently, the first discharge line 210 or the second discharge line 220 is exposed to the outside.

At this time, since the first discharge line 210 and the second discharge line 220 are able to flow in the buried pipe 450, that is, disposed in the form of a double pipe, the first and second discharge lines 210 and 220. And the buried pipe 450 are separated from each other.

Therefore, the present invention only externals the first discharge line 210 or the second discharge line 220 in the water discharge unit 200 having a problem without affecting the water supply to the other water discharge unit 300. Can be easily replaced and repaired.
