DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purification system capable of sending purified water purified by a tap water purifier using a water purifier to an optional water supply device.

[0002]

2. Description of the Related Art Currently, a water purifier for purifying drinking water is a water purifier directly connected to a faucet of a sink, and an undersink in which a water purifier is arranged below the sink to discharge purified water from a faucet. Various types such as type water purifiers are on sale. Also, in condominiums and the like, a water purification system has been developed in which a water tank for storing tap water is provided with a water purification function, thereby purifying all water supplied to each house and supplying water.

[0003]

In recent years, cases of supplying purified water not only to drinking water but also to water supply devices such as baths, washrooms, and washing machines have been increasing. However, in order to supply purified water to a water supply device such as a bath or a lavatory, it is necessary to select a water purifier that can be arranged at the faucet of the water supply device, and its installation and replacement become complicated, and individual water supply is required. Since the water purifier is disposed near the device, there is a disadvantage that the disposed water purifier becomes an obstacle when the water supply device is used.

In a water purification system in which a water storage tank is provided with a water purification function in an apartment or the like, purified water is supplied to a water supply device that does not need to use purified water because all water supplied to each house is purified and supplied. You. Therefore, the load on the water purifier increases, and the size of the water purifier increases, and when replacing the water purifier, there is a disadvantage that all the water supplied to each house must be stopped.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of such inconvenience, and it is possible to supply purified water to a plurality of water supply devices, and to easily switch between tap water and purified water. The purpose of the present invention is to develop a water purification system that can easily replace a water purifier.

That is, the gist of the water purification system of the present invention is to supply tap water to an inlet 33 of the first header 3 for distributing the introduced water to the plurality of first branch ports 31,
A water purifier 4 for purifying supplied water is connected to one of the first branch ports 31 of the first header 3, and purified water purified by the water purifier 4 is supplied to a plurality of second branch ports 61. Distribute
Water to the inlet 63 of the second header 6
The water purification system is characterized in that water is supplied to a water supply device 7 by a water guide pipe 5 through the water supply system 1 .

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail with reference to the drawings. <Embodiment 1> FIG. 1 is a conceptual diagram showing an embodiment of the water purification system of the present invention. Reference numeral 1 denotes a water supply pipe for guiding tap water (or water supplied from a water storage tank), and tap water is supplied from a water supply pipe to each household via a branch pipe 2. The branch pipe 2 is connected to an inlet 33 of a first header 3 having a plurality of first branches 31.

The first header 3 is usually made of resin such as gunmetal (bronze) or polybutene, and is installed indoors of each home or outdoors near a residence. The first header 3 has a flow path therein, and tap water guided from the inlet 33 can be distributed to a plurality of first branch ports 31 provided in the first header 3.

It is preferable to provide a valve 32 at each first branch port 31 since the first branch port 31 can be selectively used by opening and closing the valve 32. The valve provided at the branch port not normally used is kept closed. One end of the water pipe 5 is directly connected to the branch port 31 provided in the header 3, and the other end of the water pipe 5 is connected to the water receiving line of the water supply device that supplies tap water among the water supply devices 7. Thus, tap water can be supplied to the water supply device. When the water guide pipe 5 is a hose made of resin or the like, the first branch port and the water supply device can be connected to each other by being curved so that the water guide pipe does not interfere.

In one of the first branch ports 31 of the first header 3
Connects the water inlet of the water purifier 4 containing the filter agent inside.
Continue. The outlet of the water purifier 4 for discharging purified water is the first head.
Introducing a second header 6 with a separate distribution path from the header 3
Connect to mouth 63. The purified water introduced is the second header 6
Are distributed to a plurality of second branch ports 61 provided in the first branch. second
Each of the branch ports 61 is provided with a valve 62.
The opening of the valve 62 allows the branch port 61 to be used selectively.
Can be used. First header 3 and second header 6
Is preferably disposed near each other. Second head
One end of the water pipe 5 is connected to the second branch port 61 provided in the
Of the water supply device that supplies purified water
By connecting the other end of the water pipe 5 to the water receiving line,
And supply purified water from the second header to multiple water supply devices.
I can.

Although the size and shape of the water purifier 4 are not particularly limited, it is preferable that the filter can be easily replaced with a filter medium and has high pressure resistance and is compact. The filter material provided in the water purifier is not particularly limited, and activated carbon, ion exchange resin, calcium sulfite,
Fill and use a filtering material such as a hollow fiber membrane according to the required properties of purified water.

[0012] In the water purification system of the present invention, if the water guide pipe is inserted into the sheath pipe and guided to the water supply device,
It is preferable because the water pipe can be connected to the water supply device without obstruction, and the first branch port and the water supply device or the second branch port and the water supply device can be easily communicated.

The sheath tube referred to in the present invention is a pipe made of plastic or metal, and has an intermediate portion other than the inlet and outlet of the pipe laid under the floor, ceiling and side walls. The inlet of the sheath tube while arranged open in the vicinity of the first header and the second header <br/>, by opening disposed in the vicinity of the outlet of the sheath tube and each of the water supply device, a first header < The first branch 31 of the header 3 or the second branch of the second header 6
Insert the water pipe connected to the fork 61 from the sheath pipe inlet,
By penetrating through the sheath pipe and exiting from the outlet and connecting it to the water receiving line of the water supply device, most of the water conduit will pass under the floor, behind the ceiling, inside the side wall, and supply water to the water supply device, which is a daily life. It does not get in the way.

According to the water purification system of this embodiment, the purified water is
Other than the water pipe connected to the water receiving line of the water supply device you want to supply
Since you only need to connect the end to the second branch of the second header,
Even if you have more than one water supply device you want to supply purified water,
It is possible to supply purified water. Also, multiple water purifiers
The water supply equipment is not located near
The water purifier does not get in the way when using
If one of the water purifiers deteriorates, replace one water purifier.
Maintenance can be easily performed.
