2. Description of the Related Art In a water faucet in which a valve body is housed and a water passage is opened and closed by the valve body to discharge water from a water discharge port and stop water, a conventional water faucet has a water passage formed therein. The body has a bag shape as a whole. FIG. 3 shows a single faucet as a typical example thereof, and in the figure, reference numeral 200 denotes a main body having a bag shape as a whole. A water discharge pipe 204 having a water discharge port 202 at its tip is provided in the main body 200.

In FIG. 2, a connecting pipe portion 206 for connecting to a pipe is integrally formed in a form protruding downward in the drawing.

[0003] A stepped surface 208 is formed on the main body 200, and the stepped surface 208 and a fixing nut 210 screwed to a male screw on the outer peripheral surface of the connection pipe portion 206 are formed.
The main body 200 is fixed to the mounting base such that the mounting base such as a counter is vertically sandwiched therebetween through the triangular packing 212.

Reference numeral 214 denotes a valve body provided inside the main body 200. The valve body 214 is separated from a valve seat 216 integrally formed inside the main body 200, or is seated on the valve seat 216, so that the valve body 214 is provided. The water passage 218 formed inside 200 is opened or shut off. As a result, water discharge from the water discharge port 202 and water stoppage are performed. 22
0 is a spindle, 222 is the spindle 220
Is a handle for operating the valve element 214 by rotating the.

[0005]

As shown in the figure, since the main body 200 has a bag shape as a whole, the conventional main body 200 is integrally formed with the water discharge pipe 204 and the connecting pipe 206. It consisted of metal castings. However, when the main body 200 is formed as a cast article integral with the water discharge pipe 204 and the connection pipe section 206, the cost is inevitably increased. Although the above description has been made by taking a single faucet as an example, the same problem occurs in other faucets.

[0006]

The faucet of the present invention has been devised to solve such a problem. According to the first aspect of the present invention, there are provided (a) a main body having a bag-like shape as a whole to form a water passage therein, and (b) provided inside the main body and separated from a valve seat or (C) a water faucet including a valve body that sits on a valve seat to open and close the water passage and a water discharge pipe that discharges water from a water discharge port at a distal end of the water faucet; Is characterized in that the primary part and the secondary part on the downstream side are formed as separate members.

According to a second aspect of the present invention, in the first aspect, the secondary side portion is made of a resin.

According to a third aspect of the present invention, in any one of the first and second aspects, the secondary side portion and the water discharge pipe are integrally formed.

According to a fourth aspect of the present invention, in any one of the first to third aspects, the primary side portion is integrally formed with a connection pipe portion for connection to a pipe.

According to a fifth aspect of the present invention, in any one of the first to fourth aspects, the faucet is a single faucet.

[0011]

As described above, according to the present invention, the valve seat of the main body and the primary portion upstream from the valve seat and the secondary portion downstream from the valve seat are formed as separate members. By doing so, the secondary part of the bag-shaped main body can be made of resin (claim 2). Thereby, the cost of the faucet can be reduced.

In this case, the water discharge pipe can be formed integrally with the secondary part of the main body (claim 3). In this case, when the secondary part is made of resin according to claim 2, the water discharge pipe is also made of resin. still,
In the present invention, the primary side portion of the main body can also be made of resin.

[0013] A connection pipe portion for connection to a pipe can be integrally formed on the primary side portion (claim 4).
The present invention is particularly applicable to a single faucet (claim 5).

[0014]

An embodiment in which the present invention is applied to a single faucet will be described in detail with reference to the drawings. In FIG. 1, 10
Reference numeral denotes a main body forming a water passage 12 therein in a bag shape as a whole, and reference numeral 14 denotes a water discharge pipe extending from the main body 10. The water discharge pipe 14 has a water discharge port 16 at the tip, and water supplied through the water passage 12 is discharged from the water discharge port 16.

From the main body 10, a connecting pipe portion 18 for connecting to a pipe projects downward in the figure. An external thread is formed on the outer peripheral surface of the connection pipe portion 18, and a fixing nut 20 is screwed into the external thread. The main body 10 has a stepped surface 22 formed therein.
Thus, a single faucet is fixed to the mounting base 26 such that the mounting base 26 such as a counter is sandwiched from both upper and lower sides via the triangular packing 24.

Reference numeral 28 denotes a valve body which opens and closes the water passage 12 by being separated from or seated on the valve seat 30 formed inside the main body 10, and 31 is a spindle,
Reference numeral 32 denotes a handle fixed by a set screw 34 so as to rotate integrally with the spindle 31. The spindle 31 is provided with a large-diameter portion 36, and a male screw 38 is formed on the outer peripheral surface of the large-diameter portion 36.

In the case of this single faucet, when the handle 32 is rotated while the valve body 28 is open, the spindle 31 which rotates integrally with the handle 32 becomes the male screw 38 and the female screw 4.
0 is pushed downward in the figure by the screw feed action with
8 is pressed against the valve seat 30. On the other hand, when the handle 32 is rotated in the opposite direction, the spindle 31 is pulled upward by the screw feeding action in the opposite direction to the above, and the valve body 28 is opened by the action of the water supply pressure.

In this embodiment, the main body 10 is composed of an inner cylinder 42 and an outer cylinder 44 which are separate members. That is, the valve seat 30 and a primary portion upstream thereof are configured as an inner cylinder 42, and a secondary portion downstream thereof is configured as an outer cylinder 44. Here, the outer cylinder 44 extends to the position of the mounting surface of the mounting base 26, and the same portion is fitted over the inner cylinder 42 to cover it. In this example, the outer cylinder 44 is formed integrally with the water discharge pipe 14 and the whole thereof is made of resin.

On the other hand, the inner cylinder 42 is provided with the valve seat 30 and the female screw 40 as shown in FIG. 2, and an opening 46 is formed at a position between them. Water flowing from the upstream side of the valve seat 30 through the water passage 12 flows into the water discharge pipe 14 from the opening 46,
Water is discharged from the water outlet 16 at the tip.

As shown in FIG. 2, the inner cylinder 42 is provided with a flange portion 48 protruding radially outward, and the lower surface of the flange portion 48 is the stepped surface 22. The stepped surface 22 sits on the upper surface of the mounting base 26. In the present embodiment, the connection tube 18 is integrally formed with the inner cylinder 42. Here, the inner cylinder 42
And the connection pipe part 18 can be comprised by a metal cutting product. Alternatively, it can be made of resin.

According to this embodiment, the inner cylinder 42, which is the primary side of the main body 10, and the outer cylinder 44, which is the secondary side, are formed as separate members. Since the cylinder 44 is made of resin together with the water discharge pipe 14, the cost of the faucet can be reduced.

Although the embodiment of the present invention has been described in detail above, this is merely an example, and the present invention can be applied to a two-handle mixing faucet other than the above-mentioned single faucet and other faucets. However, various modifications can be made without departing from the spirit of the invention.
