The present invention relates to a piping system installed for supplying cold water and hot water in a faucet, a washing faucet, a faucet faucet, or a faucet in a building such as a house, an apartment, an officetel, a hotel, a condo, and the like. By supplying cold water and hot water by using supply pipes, the equipment cost incurred in plumbing equipment can be greatly reduced, work efficiency can be improved, and cold and hot water piping system using one supply pipe can shorten the construction period. It is about.

In general, plumbing facilities for supplying cold and hot water to faucets such as bathtub faucets, sink faucets, and wash faucets are being constructed in buildings that are built for human residence such as houses, apartments, officetels, hotels, inns, and condos. .

Such a plumbing facility includes a boiler 1, a cold water supply pipe 2 and a hot water supply pipe 3 connected to the boiler 1, the cold water supply pipe 2 and a hot water supply pipe 3 as shown in FIG. The valve body of the use faucet 4 to which this is connected is comprised.

Therefore, when the user wants to use cold water or hot water, the user adjusts and opens the valve body (shower, faucet, etc.) installed in the use faucet 4 to open the hot water or the unheated cold water heated by the boiler 1. Cold water supply pipe (2) and hot water supply pipe (3) is used to receive the supply.

However, in the case of the conventional piping system, the hot water supply pipe (3) for supplying the hot water heated by the boiler to the use water and the cold water supply pipe (2) for supplying the cold water unheated by the boiler is used separately installed Connected to the faucet so that the hot water and cold water are supplied separately to the use faucet, and then the user controls the valve body in the faucet so that the cold water or the hot water in which the cold and hot water are properly mixed is supplied from the valve body. Therefore, there is a problem that two supply pipes must be installed in the same line, respectively.

That is, since two supply pipes are installed separately, the cost of materials can only be doubled, causing a cost increase, and the installation time is considerably delayed due to the installation of two supply pipes separately by the worker, thereby greatly reducing workability. .

In particular, the cost of constructing a cold / hot water piping system in consideration of the fact that in the current society where resources are gradually depleted and the value of raw materials is continuously increasing, two supply pipes have to be installed to supply cold water and hot water. This problem is inevitably increased.

Looking at the conventional cold and hot water piping system, the construction method of the cold and hot water piping system patent registration No. 55681 has been devised, which is composed of a box-shaped case with an open front as described in the claims of the registered notification. It is embedded in the wall, but the opening door is installed in the front opening, and the drainage induction pipe is installed by drilling the drain hole at the bottom, and the upper part is connected to the drain hole at the bottom of the distributor and the lower part is located near the building drain. Distributor connection process for setting the double pipe, which is the cold and hot water pipe through the unit, faucet arrangement process for constructing a general water receiving box consisting of a case and an opening door having a pipe entrance, and inducing the double pipe of the distributor with the water receptacle The double pipe is fixed to the coupling line through the binding line, so that the double pipe is supported around the double pipe In the construction method of the cold and hot water piping system consisting of a power receiving box connection process and a faucet connection process in which a load support is installed on the reinforcing bar, the faucet connection process is one end of the flexible hose connecting the soft pipe of the double pipe and the faucet. The other end of the flexible hose is connected to the faucet, and the other end of the flexible hose is connected to the faucet, and the friction protrusion and the repair hole are formed in the opening and closing door, and the edge of the repair hole is opened to open and close the open plate. It is configured to be coupled to the flexible hose and at the same time fixed to the open plate through the socket insertion hole formed in a part of the open plate is inserted and fixed to the connector of the faucet.

Therefore, it is intended to facilitate the construction and to prevent damage to the cold and hot water pipes.

As another example, a piping system of a heating hot water boiler, which is registered in Korean Patent No. 104168, has been devised, which is a small circulation using a large circulation circuit for heating a heating load in a heating hot water boiler as described in the registered publication. In constructing the circuit, a bypass pipe is connected to the outlet pipe for supplying heating water to the heating load, and the bypass pipe is connected to a heating pipe for circulating the circulating water to the heat exchanger, and the amount of opening due to the differential pressure of the circulating water is increased. The control valve to be controlled is connected to one side of the bypass pipe, the return pipe for returning the heating water from the heating load is connected to the heating pipe, the opening and closing valve for opening and closing the return pipe at one end of the return pipe is installed have.

Therefore, by using the opening and closing valve for opening and closing the return pipe, and the control valve for opening and closing the bypass pipe in an appropriate amount according to the pressure of the pipe can be replaced by the role of the expensive three-way, it is possible to reduce the price of the product first, simple Because of the structure, it is possible to improve the reliability by reducing the failure, and to effectively cope with the blockage of the pipe, thereby improving the usability and durability of the device.

However, the cold and hot water supply pipes applied to the conventional cold and hot water piping systems cannot solve the above-described problems, since two supply pipes must be separately installed so that the cold water and the hot water are supplied separately.

The cold and hot water piping systems, which are conventionally constructed or proposed, are only trying to solve the problems such as improving the workability, preventing the breakage of the hot and cold water pipes, and preventing the blockage of the hot and cold water pipes, and are separated from the reality that only two supply pipes can be installed. There is a problem that can not be limited due to the cost saving or easy construction accordingly.

The present invention has been devised to solve the problems of the conventional cold and hot water piping system, a supply pipe for connecting the use faucets such as tub faucets, wash basins, washing faucets, and the like to connect the boiler for supplying warm water to supply hot water to one supply pipe It is connected to the construction, but through the one supply pipe cold water as well as the hot water is further provided with a mixer for mixing the cold water and hot water supplied from the boiler so that the cold water and hot water is supplied together by one supply pipe to provide a conventional two supply pipe The purpose is to provide a cold and hot water piping system using one supply pipe to reduce the cost caused by each construction to one supply pipe, thereby greatly reducing the cost, reducing working hours, and greatly improving work efficiency. There is this.
