Abstract

PROBLEM TO BE SOLVED: To facilitate the connection work and reduce cost by connecting a flow-in port side of a valve mechanism of a water faucet main body with a connection pipe which is communicated with a supply source by using a flexible pipe. SOLUTION: One end of flexible pipes 28 and 29 is fitted and mounted in flow-in ports 19 and 20 of hot water which are communicated with a valve mechanism of a water faucet main body 6 of a water faucet metal fitting 27, and an O ring 30 is externally fitted for sealing. The other end of the flexible pipes 28 and 29 passes through the inside of a cover 3 of the water faucet main body 6 and passes through a cylindrical screw part 31 which protrudes and is formed on a lower face side of a bottom plate 2 to guide it to the outside, and a cap nut 32 for connection is attached to a tip thereof. The cylindrical screw part 31 is fixed on a mating member of a wash counter, and the cap nut 32 for connection at the other end of the flexible pipes 28 and 29 is connected with the other flexible pipe to connect and communicate with a hot water source or a water supply source. Since brazing of a copper pipe and integral casting formation of the water faucet main body 6 are unnecessary, it is possible to simplify the assembly work of the water faucet metal fitting 27 and reduce cost.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is designed to easily connect an inlet port of a member forming a valve portion of a faucet body and a water and hot water supply connection pipe by using a flexible pipe. It is about technology.

[0002]

2. Description of the Related Art Normally, the water or hot water flow passages of a faucet metal fitting are of the type shown in the partial vertical sectional views of FIGS. 3 and 4, and of the type shown in the partial vertical sectional view of FIG. There is.
The type shown in FIGS. 3 and 4 is one in which the inflow passage between the valve mechanism portion and the leg portion of the faucet body is connected by using an introduction pipe, and the type shown in FIG. In the above, the inflow passage between the valve mechanism portion and the leg portion of the faucet body is formed integrally with the faucet body during casting.

The faucet fittings of the type shown in FIGS. 3 and 4 are single lever type hot and cold water mixing faucets. As shown in the figure, this hot and cold water mixing faucet 1 includes a bottom plate 2 and a cover 3.
At the center of the base outer shell body 4 consisting of
The water faucet body 6 is erected via a and 5b. The bottom plate 2 and the cover 3 are connected by a screw member (not shown). Then, from the lower surface side of the bottom plate 2 through the cylindrical pin members 5a, 5b to the faucet body 6, screw members 7a, 7b.
The faucet body 6 is fixed to the bottom plate 2 by screwing.

A water outlet portion 9 having a water outlet 8 is rotatably fitted on the outer peripheral surface of the faucet body 6 on the lower side. Further, the cap 1 is provided on the outer peripheral surface of the faucet body 6 on the upper side.
0 is externally fitted and attached by screwing. On the other hand, on the upper surface side of the faucet body 6, the fixed disk 11 and the movable disk 1 are provided.
A valve mechanism 13 composed of two disc valve bodies 2 and 2 is provided. By operating the movable disk 12 with a single lever 14 penetrating the head of the cap 10, the flow rate (mixing ratio) of hot water and water can be controlled. Thereby, the temperature of the hot water discharged from the water discharge port 8 can be adjusted to a desired value, and at the same time, the flow rate can be adjusted.

[0007] Thus, on both ends of the bottom plate 2, there are attached legs 15 and 16 which serve as both the hot and cold water mixing faucet 1 and the hot and cold water inflow passages. This leg 15 and 1
6 is a copper introducing tube 17 disposed in the base outer shell body 4
Hot water and water inlets 19 and 2 of the faucet body 6 through
0. Normally, the introduction pipes 17 and 18
Both ends of each are connected to the faucet body 6 and the legs 15 and 16 by brazing. Moreover, each connecting portion of the introduction pipes 17 and 18 is a portion 1 bent into an L shape.
It has 7a, 17b and 18a, 18b.

In FIGS. 3 and 4, reference numeral 21 is a rubber packing disposed on the lower surface side of the bottom plate 2, and 22 is a counterpart member for mounting the hot and cold water mixing faucet 1 such as a counter of a vanity or a washbasin. . Further, in FIG. 4, 23 is an outlet for hot water formed in the faucet body 6, and 24 is a mixing chamber.

On the other hand, the faucet fitting of the type shown in FIG. 5 is also a single lever type hot and cold water mixing faucet 25. The hot and cold water mixing faucet 25 is formed by casting the entire faucet body 26, and is the hot water of the faucet body 26 that communicates with the valve mechanism 13 (the same as that shown in FIG. 4; see this). The inflow passage 29 between the water inlets 19 and 20 (see FIG. 3) and the legs 27 and 28 is integrally cast with the faucet body 26.

[0008]

By the way, these hot and cold water mixing faucets 1 and 25 have the following drawbacks. That is, in the hot and cold water mixed faucet 1 shown in FIGS. 3 and 4, the flow of hot water and water of the faucet main body 6 through the copper introduction pipes 17 and 18 arranged in the base outer shell body 4. The inlets 19 and 20 are connected to the legs 15 and 16. This connection must be performed by brazing both ends of each of the introduction pipes 17 and 18 since they are made of copper.

Such brazing must be arranged concentrically at the respective connecting portions, it is difficult to align them, and it is necessary to finish the receiving side and the inserting side with high precision. Because it is a work with a small diameter,
The work itself was difficult.

In addition, the connecting portions of the introduction pipes 17 and 18 have L-shaped bent portions 17a and 17b, and 1
8a and 18b, the dimensional accuracy is also required for the bending work, and if too much force is applied, the bending portion becomes flat and there is a problem that it cannot be used.

On the other hand, in the hot and cold water mixing faucet 25 shown in FIG. 5, the entire faucet body 26 and the inflow passage 29 formed therein are integrally cast, resulting in a high material cost and thereafter There is also a problem that the processing cost to be performed is also high.

[0012]

SUMMARY OF THE INVENTION The present invention has been made by improving the above-mentioned problems in view of the above-mentioned problems, and uses a flexible pipe to communicate with the inlet side of the valve mechanism of the faucet body and the water supply source. By connecting the connecting pipe, the connection work is simplified and the cost is reduced.

Therefore, the means adopted by the present invention to solve the above-mentioned problems is such that one end of the flexible pipe is connected to the inlet of the member forming the valve portion of the faucet body and the other end is connected to the other end. It is a connection structure of an introduction pipe of a faucet fitting, which is characterized in that it is led out to the outside through the outer shell of the faucet body.
