Description

Improved Piping Structure of Single lever faucet

The present invention relates to a single lever faucet for supplying cold and hot water and mixed water having an improved piping connection structure, and more particularly to a cold, hot water and mixed water connection pipe connecting a single lever faucet and a water discharge port for supplying cold and hot water and mixed water. It is easy to separate / combine by improving the coupling structure and connection structure to use engineer plastics and synthetic resin materials (PB, PE-RT, PPR, PE) in bronze / brass materials. It is easy to adjust the length of minute pipe, change the bending angle of the pipe freely, and it is easy to replace the pipe during repair, and even if the interval between the single lever faucet and the water jetting port is narrow, no bending occurs and the water hammer is prevented to prevent breakage of the single lever faucet. It can be used to reduce copper ions and fresh water generated by using bronze, brass and copper pipes, and to replace copper products that lead to harmful lead components. Air costs are inexpensive and environmentally friendly relates to a hot water pipe and a mixed feed for single lever faucet having a connection structure improved.

Generally, the single lever faucet is a high-grade faucet that can simultaneously control temperature and flow rate by using one lever so that hot water and cold water are mixed together and discharged through one or two discharge ports. It can be used anywhere, sink, sink, bathtub, etc.

However, the one-hole type single lever faucet 100, such as a sink and wash basin using such a single lever faucet, has three pipes consisting of hot water, cold water, hot water + cold water or a hot water, cold water, hot water + cold water, withdrawal pipe on a very narrow bottom surface. Four pipes formed are connected to each other, and as shown in FIGS. 1 to 2 showing the single lever faucet 100 installed in the sink, the distribution nozzle pipe body 110 of the single lever faucet 100 has a plurality of cold at a narrow bottom. , The flexible hose 120 for supplying hot water and mixed water is formed in a structure in which the goggles are coupled, and a plurality of female threads or male threads for connection with the flexible hose 120 are provided in a narrow space. It is not possible to make an injection molding.

Accordingly, the distribution nozzle pipe 110 has a problem in that it can only be manufactured by casting or forging of bronze / brass material that can be post-processed with a plurality of female threads or male threads in a narrow space. The flexible nozzle 120 was screwed to the distribution nozzle pipe 110 manufactured as described above, or the copper pipe was welded to prevent leakage.

However, as shown in FIG. 3, the conventional pipe coupling method as described above is impossible to replace the pipe when welded, and even when screwed together, the screw portion is epoxy-bonded to prevent screw loosening and leakage due to water hammer. Fixed and fixed by fixing the pipe is virtually impossible to replace, there is a problem that the replacement and replacement cost of the single-lever faucet can not be replaced during the aging and repair and increase the cost of repair.

In addition, the flexible hose 120 used in the conventional one-hole type single lever faucet 100 for mixing cold and hot water installed in the sink and the sink is made of a flexible hose made of metal as shown in FIG. If the pipe is short because it can not be adjusted according to the site situation, the connection itself is impossible, and if the pipe is long, it is difficult to be distorted due to its sleekness and aesthetic appearance because it is left bent many times in a streamlined form under the sink or sink. .

In addition, the flexible hose 120 used in the conventional one-hole type single lever faucet 100 for mixing cold and hot water installed in the sink and the wash basin alternates the inner tube of rubber material with the Teflon metal strand due to the characteristics of the flexible hose made of metal. It is a structure that weaves and surrounds and forms a shell, and the replacement cycle of the flexible hose made of rubber material is made of polybutylene pipe (PB pipe), polyethylene pipe (PE pipe) and crosslinked-polyethylene pipe (PE-X pipe). Unlike the soft main pipe, there was an inconvenience of managing a separate replacement time.

In addition, chlorine is used to manage the water quality. At this time, EPDM material, which is a material in the flexible hose, may cause a chemical reaction when the chlorine is used excessively, and the black component of rubber may be diluted in the tap water. , When using the hot water pipe and the inner pipe of the boiler as the copper pipe, there was a problem that copper ions are generated to cause corrosion of the material.

In addition, the flexible hose 120 used in the conventional one-hole type single lever faucet 100 for mixing cold and hot water installed in the sink and wash basin has a problem that the bending is not free at various angles due to the characteristics of the flexible hose made of metal, and is limited. When the water hammer phenomenon is repeatedly bent in a state of bending a lot, the flexible hose 120 is often damaged even when repairing by moving the sink, and the EPDM material and the Santo Tran material are bent more than 90 degrees There was a problem that the water does not flow due to bending without restoration.

In addition, the distribution nozzle pipe 110 of the flexible hose 120 used in the conventional one-hole type single lever faucet 100 for mixing cold and hot water installed in the sink and the sink is made of copper or brass. This is a metallic stain that is caused by oxidation of ions.As a result, when you look at the bottom of a wash basin or bathtub after using cold or hot water through a faucet, you see a blue-green deposit and blue stains on a cloth. The lead component is detected in cold and hot water used as drinking water, and the government regulates the use of the same pipe.

In addition, the conventional one-hole type single lever faucet 100 for mixing cold and hot water installed in the sink and the sink is made by using the case 104 and the distribution nozzle pipe 110 and the metal flexible hose 120 made of copper or brass. Due to the increase in manufacturing costs there was a problem that the price competitiveness is lowered.

The present invention is devised to solve the conventional problems as described above, and more specifically, the cold, hot and mixed water connecting pipe and distribution nozzle pipe connecting the single lever faucet and the water discharge port for supplying cold and hot water and mixed water It is easy to separate / combine by improving the coupling structure and connection structure so that engineer plastic and synthetic resin materials (PB, PE-RT, PPR, PE) can be used in bronze / brass material. Easy to change the bending angle of the pipe freely, easy to replace the pipe during maintenance, and even if the gap between the single lever faucet and the water inlet is narrow, no bending occurs and the water hammer does not occur, so the single lever faucet (shower, bathtub, sink, sink, Copper ion elution and fresh water generated by using bronze, brass and copper tubes, and lead constituents harmful to human body To replace the product in providing a hot and cold water and mixed water supply for single lever faucet having a pipe connection structure, while the cost is low as it is an object of the environmentally improved.
