Abstract

PROBLEM TO BE SOLVED: To provide a usable water use terminal capable of greatly saving piping materials and executing labors and thawing frozen members in a single motion by means of a centralized operation, in a cold district. SOLUTION: The pipe from a water supply lead-in pipe is branched into a hot-water passage leading hot-water to a centralized temperature adjustment header 3 through a hot-water supplier A and water passage directly leading it to the header and mixing and adjusting the hot-water and cold-water and distributing it to a hot-water supply terminal and a water supply terminal to directly lead pipes to respective terminals. Further, heating wires coated with flame-retardancy resin are laid along the pipe wall to constitute a serial circuit against an electric source. In this way, the thawing operation can be carried out by turning on/off the electric source, using a synthetic resin pipe coated with a heat retaining material on the external side.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plumbing system for a residence such as a prefabricated detached house or a detached house.
The present invention relates to a plumbing method capable of centrally controlling the supply of hot water to a water supply terminal such as a bathroom, a toilet, a wash basin, and a washing machine, and a temperature control of a water supply temperature, and a centralized temperature control header and piping materials used for the piping. .

[0002]

Conventionally, water plumbing pipes for residential use have been arranged such that individual water flows from a hot water pipe through a heating water heater and a cold water pipe from a water supply pipe are distributed in respective headers, and hot water and Cold water is specially supplied to a terminal faucet portion of a kitchen, a bathroom or the like, and hot water and cold water are mixed by a terminal mixer tap to control the temperature of the water used.

[0003] Therefore, two pipes, a hot water pipe and a cold water pipe, are required from the distribution header to each terminal, so that the use of twice as much material and space for both the pipe material and the pipe space occurs. I have.

Further, in the conventional system, each terminal is provided with a two-valve type temperature control mechanism, and it is necessary to use a mixing faucet.

[0005] Furthermore, with respect to water plumbing pipes for residential use, no measures are taken against freezing of the pipes in cold regions or in winter, and a great deal of labor must be spent on thawing when frozen. There were also problems.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has been made to solve the above-mentioned problem by connecting a pipe from a water supply inlet pipe to a centralized temperature control header via a heated water heater and a direct concentrated water temperature. In addition to branching into a water supply path leading to the control header, the centralized temperature control header controls mixing of hot water and cold water and distributes the hot water to the hot water supply terminal and the water supply terminal so that direct piping to each terminal is performed.

[0007] The centralized temperature control header incorporates a flow control valve for hot water and cold water which can be remotely operated, and has a distribution channel to each terminal and a piping head, and is installed at each hot water supply terminal. An electromagnetic or electric signal emitted from the operation panel operates the flow control valve so that the mixing control of hot water and cold water can be performed.

[0008] Further, in the cold district of water plumbing pipes for residential use and in the freezing of the pipe section in winter, a heat generating wire whose pipe wall is coated with a flame-retardant resin is arranged in series with a power supply in a series circuit configuration. Then, using a synthetic resin tube such as a crosslinked polyethylene tube whose outside is covered with a heat insulating material, the thawing operation can be performed by turning the power on and off, and the thawing operation is issued from the operation panel installed at each hot water supply terminal. It can be done by electromagnetic or electrical signals.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a cold water supply pipe from a water supply pipe through a water meter, which branches into a flow pipe 12 to a heating water heater A and a flow pipe 13 to a cold water header 32 of the centralized temperature control header 3 at a branch portion 11. Thus, a water supply flow path to each is formed.

The supply water of the flow pipe 12 is heated in the heating water heater A, and the hot water supply pipe 2 controls the centralized temperature control header 3.
To the mixing section 33 via a hot water header 31 having a built-in flow control valve, and the supply water of the flow path pipe 13 is distributed in a distribution flow path in the header 3 to a flow path 4 to a terminal using only cold water such as a flush toilet. The water is distributed and supplied to a flow path leading to a mixing section 33 through a cold water header 32 having a built-in flow control valve.

The mixing section in the header 3 includes a hot water header.
The hot water and the cold water, which are adjusted to a predetermined flow rate by the electromagnetic or electric signal emitted from the operation panel 6 installed at each terminal unit from the cold water header 32 or the centralized operation panel installed at a predetermined place from the header 31, are mixed and joined. They are joined at 33 and adjusted to the use temperature at the terminal, and supplied to the use terminal through the flow path 5.

Next, a pipe material used in an area where there is a risk of freezing in winter will be described. A heating wire 1b coated with a flammable resin is provided along a power supply in a series circuit configuration, and the outer periphery thereof is integrally coated with a flow path tube main body 1a by a heat insulating material 1c.

Since the heating wire 1b is made of nickel wires of 13A and 14A and has a serial circuit configuration with respect to a power supply which is turned on and off by the operation panel 6, the operation of the power on / off operation section 63 of the panel 6 is performed. When power is input to the required portion, the heating wire 1b of the required portion generates heat and heats the pipe body 1a to perform thawing.

The power supply is a dedicated power supply of 100V, 15A and power consumption of 2000
It is about Wh, and the thawing time is about 30 to 40 minutes.
If necessary, the power may be turned on and off automatically by the temperature sensor.

Since the present invention is constructed as described above, the plumbing material and the construction labor can be largely saved, and in a cold region, the freezing part can be thawed with a single touch by a centralized operation. Was able to be provided.
