Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art Generally, there is provided a main body for forming a flow path of water and controlling the flow rate of the water, a lever for controlling the flow rate is provided on the main body, and a spout for guiding outflowing water is attached. Faucet is known. Hereinafter, the faucet having the 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 used.

FIG. 6 shows a hot and cold water mixing faucet having the above-mentioned conventional structure. Conventional hot and cold water mixing tap 5 shown in the figure
1 has a main body 52 and a spout 53. Body 5
2 is an integrally molded product of casting, and has a mounting portion 55 that can be fixed to the opening 54a of the mounting plate 54 in the lower portion. The main body 52 has a valve body that adjusts 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 on the upper portion of the main body 52.

The mounting portion 55 has a step portion 58 having a diameter larger than that of the opening portion 54a of the mounting plate 54, and a small diameter screw portion 59 protruding 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.

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 are provided with cold water flow paths and hot water flow paths formed in the bulging portion 56 (see FIG. Connected (not shown).

A valve body accommodating chamber 64 for accommodating the valve body 63 is formed at one end of the bulging portion 56. A plurality of valve bodies are incorporated in the valve body storage chamber 64. A lever 65 for operating the valve body is attached to the 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 passage and the cold water passage formed in the main body. The cold water and the hot water are mixed at a predetermined ratio depending on the opening / closing 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-mentioned structure, since the faucet body has a complicated water flow passage inside, the water is mixed to realize the complicated internal shape. The plug body was integrally molded by casting. However, in general, the production of a water faucet component by casting requires a large-scale production apparatus and complicated steps, which makes the production difficult. Therefore, there has been a demand for the development of a faucet having a simpler structure and easy to manufacture.

On the other hand, in the field to which this technology belongs,
There has been a demand for forming the 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 water mixing faucet having the above structure, since the faucet body has many hollow portions, the pressure resistance and the like are insufficient and the resin cannot be used.

Therefore, an object of the present invention is to meet the above-mentioned demand,
It is to provide a faucet that is simple in construction and easy to manufacture.

[0011]

A water faucet according to the present invention includes a base for fixing the water faucet, a main body for controlling a flow rate combined with an upper portion of the base, and a body attached to an upper portion of the main body. A spout for guiding water, the base has a cavity for guiding pipes or guiding water, the body has a housing member having a flow path communicating with the cavity of the base, and a valve. A body portion and an operating portion for operating the valve body of the valve body portion, and the main body portion and the spout are water by inserting the base end portion of the spout into a spout insertion port formed in the main body portion. It is characterized in that the flow paths of are communicated with each other.

Another water faucet according to the present invention is characterized in that at least a portion having a passage for guiding a water flow path or a pipe of a base portion is formed of resin.

Further, another water faucet according to the present invention is characterized in that at least a portion of the main body portion having a water flow path is formed of a resin.

Further, in another faucet according to the present invention, a base portion and a main body portion penetrate the base portion, an upper end portion is connected to the main body portion, a lower end portion projects downward from a mounting plate of the faucet and is screwed with a female screw member. It is characterized in that it is integrally fixed to the mounting plate by a fixing rod to be fitted.

[0015]

The faucet according to the present invention is composed of three parts: a base part, a main body part and a spout. By dividing the entire faucet into three constituent parts, the shape and structure of each constituent part is simplified, and the facilitating manufacture of the constituent parts facilitates the manufacture of the entire faucet.

Further, the faucet of the present invention has a base portion and a main body portion combined, and the spout base end portion is inserted into the spout insertion opening of the main body portion to complete the assembly. is there.

Particularly, in the faucet of the present invention in which the base portion and the main body portion are fixed to the mounting plate by the fixing rod, the fixing rod is attached and the spout is inserted and the assembling and attaching of the faucet are completed at the same time. Therefore, the assembling work is easier.

Further, according to the present invention, by dividing the faucet main body into the base portion and the main body portion, it is possible to make each constituent portion into a simple shape, for example, a substantially cylindrical shape. By forming the base and main body into a simple shape such as a cylinder in this way, the base and main body are divided into a complicated-shaped portion having a flow channel and a pressure-resistant portion that reinforces the flow channel. This makes it possible to manufacture the flow path portion having a complicated shape with resin or the like and the pressure resistant portion with metal or the like. In this case, the advantage of the resin that molding is easy,
A faucet that is easy to manufacture and that has excellent function and appearance can be obtained by virtue of the strength and the advantage of a metal having an excellent appearance.
