Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a faucet device characterized by the structure of the tip of a water discharge pipe.

(Prior Art) Generally, a cap made of resin is provided on the tip of a water discharge pipe of a faucet device for heat insulation or the like.

FIG. 3 shows the structure of the tip of the water discharge pipe of a conventional faucet device. As shown in the figure, this water faucet device has a tubular spout at the tip of the water discharge pipe body 100. Water outlet fitting 1
02 is attached, and the metal fitting 102 is further covered with a resin cap 104 to form a water discharge pipe 105. In this faucet device, an opening 106 for forming a water discharge port is formed through the peripheral wall of the resin cap 104, and a through hole 108 is formed in the resin cap 104 in the vicinity of the opening 106. In this through hole 108, the resin cap 104 is fixed to the spout metal 102 by a set screw 110.

(Problem to be solved by the invention) However, in the above-mentioned conventional faucet device, since the metal mounting bracket 102 is simply covered with the resin cap 104 at the tip of the water discharge pipe, that is, the resin portion has a small thickness. Therefore, there is a problem that the heat insulating performance at the tip of the water discharge pipe 105 is low.

In addition, in the case of this faucet device, the resin cap 104 must be thin, and the through hole 108 for the set screw 110 must be separately processed in the resin cap 104 in the vicinity of the opening for the discharge port 106. Since the strength of the resin cap 104 becomes low in the processed portion of the through hole 108 because of this, due to the rotational force applied to the resin cap 104, the stress caused by the expansion and contraction due to heating and cooling during use, etc. There is a problem that the resin cap 104 is easily cracked from the processed portion of the through hole 108.

(Means for Solving the Problem) The present invention has been made to solve such a problem, and its gist is to have an opening serving as a water discharge port and to connect the opening and the water discharge pipe main body with each other. The tip end portion of the water discharge pipe is formed of a resin water discharge port member having a water flow passage continuous to the water flow channel, and a small-diameter fitting portion is integrally formed on the water discharge port member to form a part of its outer peripheral portion. It is made of a strength member such as a metal material, and in a state where the fitting portion is fitted into the water discharge pipe body, a set screw penetrating the pipe wall of the water discharge pipe is screwed into the strength member to fix the water discharge port member. It is in.

(Operation and Effect of Invention) As described above, the faucet device of the present invention is configured by the water discharge port member in which the tip portion of the water discharge pipe is formed up to the core portion with the resin material. Therefore, the thickness of the resin portion can be increased without increasing the outer shape of the tip of the water discharge pipe, and thus the heat insulation performance of the tip of the water discharge pipe can be improved without impairing the appearance of the tip of the water discharge pipe.

Further, in the faucet device of the present invention, a part of the outer peripheral portion of the fitting portion that is integrally molded with the spout member is formed of a strength member, and the set screw is screwed into the strength member to spout the spout. Since the member is fixed to the body of the water discharge pipe, it is not necessary to form a through hole or a screw hole for the set screw in the resin portion of the water discharge port member. There is no inconvenience that the strength is weakened.

According to the present invention, an annular groove is provided at a position apart from the tip of the fitting portion by a predetermined distance, a ring-shaped strength member is integrally fitted in the annular groove, and the outer peripheral surface of the tip end side of the groove is a water discharge pipe. It is preferable to fit it to the inner peripheral surface of the tip of the main body. With this configuration, the ring-shaped strength member can be reliably prevented from coming off by the annular groove, and at the same time, at the fitting portion between the outer peripheral surface of the fitting portion on the tip side of the groove and the inner peripheral surface of the tip of the water discharge pipe body. By arranging the O-ring, even if a gap due to expansion and contraction occurs at the boundary surface between the ring-shaped strength member and the resin material, the gap and the water passage in the water discharge pipe body can be blocked, so that through the gap. This is because it is possible to prevent water from leaking.

(Example) Next, the Example of this invention is described in detail based on drawing.

In FIG. 2, reference numeral 10 is a water discharge pipe of a water faucet, which is connected to an operating portion 12 through a pipe (not shown), and by operating an operating lever 14, hot water, cold water, or a mixed water thereof is discharged at a tip 15 (first It is designed to discharge from (Fig. 1).

The water discharge pipe 10 is mainly composed of a water discharge pipe main body 16 and has a water discharge port member 18 at its tip. The water discharge pipe main body 16 is a metal pipe having a water passage 20 inside and is rotatably held at the base end portion thereof. As shown in FIG. 1, the discharge pipe main body 16 has a small diameter on the inner surface of the opening portion on the tip end side. It has a fitting projection 22.

On the other hand, the spout member 18 is a molded product of a resin such as ABS resin, and has a large-diameter main body portion 24 and a small-diameter fitting portion extending from the base end of the main body portion 24 as shown in FIG. 26 and a water passage 28 is formed therein. Then, one end of this water passage 28 is opened at the tip end surface of the fitting portion 26 to serve as an inlet for water from the water discharge pipe main body 16, and the other end is the main body portion 24.
Is opened at the lower surface of the middle portion of the water outlet to serve as a water discharge port 15.

A peripheral portion of the opening of the water passage 28 on the discharge port 15 side is a cylindrical portion 30,
A spout cap 34 is screwed to the cylindrical portion 30 via a packing 32. A straightening member such as a net 36 is arranged between the spout cap 34 and the packing 32.

On the other hand, on the outer peripheral surface of the fitting portion 26, an annular groove 38 is formed at a position apart from the tip of the fitting portion 26 by a certain distance, and the metal ring 40 as a strength member is integrally fitted into the annular groove 38 by insert molding. Has been. Then, as shown in the figure, the fitting portion 26 is a fitting projection portion of the water discharge pipe body 16.
