[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a faucet having a faucet comprising a base, a main body and a spout, each of which is easy to manufacture and easy to assemble when mounted.

[0002]

2. Description of the Related Art In general, there is provided a main body for forming a flow path of water and controlling a flow rate of the water, a lever for controlling the flow rate is provided on the main body, and a spout for guiding the water flowing out is attached. Faucet is known. Hereinafter, a water faucet having this conventional structure will be described with reference to the drawings. In this description, a hot and cold water mixing faucet capable of mixing cold water and hot water will be described.

FIG. 6 shows a hot-water mixing faucet having the above-mentioned conventional structure. Conventional hot and cold water mixing faucet 5 shown in FIG.
1 has a main body 52 and a spout 53. Body 5
Reference numeral 2 denotes an integrally molded product having a mounting portion 55 which can be fixed to the opening 54a of the mounting plate 54 at a lower portion. The main body 52 has a built-in valve body for adjusting the flow rate and temperature above the mounting portion 55, and has a bulging portion 56 that forms a water flow path and a mixing chamber. A spout insertion port 57 communicating with the spout 53 is formed in an upper part of the main body 52.

The mounting portion 55 has a step 58 having a larger diameter than the opening 54a of the mounting plate 54, and a small-diameter screw portion 59 projecting below the mounting plate 55. A female screw member 60 is screwed onto the outer peripheral surface of the screw portion 59. By tightening the female screw member 60, the step 58 and the female screw member 6
0 clamps the mounting plate 54 and fixes the hot and cold water mixing faucet 51.

[0005] A hot water supply pipe 61 and a water supply pipe 62 are inserted inside the screw portion 59, and the upper ends of the hot water supply pipe 61 and the water supply pipe 62 have cold water flow paths and hot water flow paths (see FIG. (Not shown).

A lever 65 for operating the valve body is attached to an end of the bulging portion 56 having the valve body.

By operating the lever 65, one of the valve bodies slides and rotates to open and close the hot water flow path and the cold water flow path formed in the main body. Cold water and hot water are mixed at a predetermined ratio according to the open / close ratio of the cold water flow path and the hot water flow path, and flow out to the outside through the mixed water flow path formed in the main body and the spout 53.

[0008]

In the conventional hot and cold water mixing faucet having the above structure, the faucet main body has a complicated water flow path therein. The plug body was integrally formed by casting. However, the production of faucet parts by casting generally requires a large-scale production apparatus and complicated steps, and is difficult to produce. For this reason, there has been a demand for the development of a faucet that is simpler in structure and easier to manufacture.

On the other hand, in the field to which this technology belongs,
There has been a demand for forming the main body of the hot and cold water mixing faucet with a resin that is extremely easy to mold. However, in the conventional hot and cold mixing faucet having the above-described structure, since the faucet main body has many hollow portions, the pressure resistance and the like are insufficient, and the resin cannot be used.

Accordingly, an object of the present invention is to meet the above-mentioned demands,
It is to provide a faucet which is simple in structure and easy to manufacture.

[0011]

SUMMARY OF THE INVENTION A faucet according to the present invention has a base for fixing a faucet, a main body for controlling a flow rate combined with an upper part of the base, and an upper part of the main body. A guide member made of a resin having a cavity for guiding a hot water or water pipe or guiding the fluid, and a metal base covering an outer periphery of the guide member. A housing member made of a resin having a flow path communicating with the hollow portion of the base, a valve body, and an operation unit that operates a valve body of the valve body. A metal body cover that covers an outer periphery of the housing member, wherein the main body and the spout communicate with each other by inserting a spout base end into a spout insertion port formed in the main body; Must be configured to The one in which the features.

[0012]

[0013]

[0014]

[0015]

The water faucet according to the present invention comprises three parts: a base, a main body and a spout. By dividing the entire faucet into three components, the shape and structure of each component is simplified, and the components can be easily manufactured, thereby facilitating the manufacture of the entire faucet.

Further, the faucet of the present invention combines the base and the main body, and completes the assembly by inserting the spout base end into the spout insertion opening of the main body. is there.

In particular, in the water faucet of the present invention in which the base and the main body are fixed to the mounting plate by the above-mentioned fixing rod, the fixing rod is attached and the spout is inserted to complete the assembly and installation of the faucet simultaneously. Since it is possible, the assembling work is further facilitated.

Further, according to the present invention, by dividing the faucet main body into a base portion and a main body portion, each component can be made into a simple shape, for example, substantially cylindrical. By making the base and the main body into a simple shape such as a substantially cylindrical shape, the base and the main body are divided into a complicated shape having a flow path and a pressure-resistant part for reinforcing the flow path. As a result, the flow path portion having a complicated shape can be manufactured from resin or the like, and the pressure-resistant portion can be manufactured from metal or the like. In this case, the advantage of resin that molding is easy,
A faucet that is easy to manufacture and has excellent functions and appearance can be obtained due to the advantages of metal having excellent strength and aesthetic appearance.
