Abstract

PROBLEM TO BE SOLVED: To provide a faucet having a spout pipe, which does not allow its shower hose connected to a spout port to take up a space below a counter, and can extend its extension length provided that the faucet is of the type that includes the shower hose in the spout pipe, to thereby improve the usability and operability of the spout pipe. SOLUTION: The faucet is characterized in that the spout pipe slidably houses therein a water flowing pipe which then slidably houses therein a flexible hose having the spout port connected to the tip thereof. Therefore, the spout pipe houses therein the double-slidable water flowing pipe, and the spout port can be extended longer then a conventional one. Further, the shower hose need not be housed below the counter, and therefore it does not occupy the housing space in the counter, which leads to improved usability of the faucet.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a faucet. In particular, it relates to a water supply facility, and relates to a water discharge pipe portion of a faucet used in a kitchen or a washroom.

[0002]

2. Description of the Related Art Conventionally, in a water discharge pipe portion of a faucet used in a kitchen or a washroom, a shower hose is connected to a water discharge port to be drawn out to improve convenience. The hose was stored under the counter to which the water faucet was attached, and occupied the space inside the counter, thus impairing the storability inside the counter. Further, since water may drip down into the space inside the counter along the shower hose, it is necessary to separately install a member called a water receiving tray below the shower hose for receiving the water. As a result, there was a problem that the storage space in the counter was occupied, and the cost increased. Further, there is a water faucet of Japanese Patent Laid-Open No. 11-200438 in which a shower hose is housed in a water discharge pipe, but this is a factor that restricts the drawing length due to its structure and hinders its convenience.

[0003]

A conventional water faucet with a water spout that has a shower hose stored in the counter as shown in FIG. 8 impairs the storage space in the counter. In addition, as shown in FIG. 9, since the water faucet that stores the shower hose in the water discharge pipe has a short pull-out length,
Even if the hose itself is flexible, it is not enough to wash every corner of the kitchen sink, and it has a factor that hinders its convenience or makes it impossible to exhibit its convenience. The present invention is
The present invention has been made to solve the above problems, and an object of the present invention is to provide a faucet having a water discharge pipe portion of a pull-out type that does not impair convenience.

[0004]

In the first aspect of the invention, there is provided flexibility in which a water pipe having a tubular shape is slidably accommodated in the water discharge pipe, and a water discharge port is connected to the tip of the water discharge pipe. Provided with a faucet that slidably houses a hose.

As a result, a double slidable water pipe is housed inside the water discharge pipe, the water discharge port can be drawn out for a longer time, and there is no need to store the shower hose under the counter. Further, the convenience can be improved without occupying the storage space in the counter.

In a second aspect of the invention, there is provided a faucet having a bent portion at the base end side of a water pipe.

According to the present invention, since the bent portion is formed on the proximal end side of the water pipe so as to be bent, the operability when pulling out the water outlet can be further improved. It is especially effective when the water pipe is rigid.

In the third invention, of the two O-rings for keeping the water pipe and the flexible hose watertight, the tightening margin of the O-ring on the flexible hose side is smaller than that of the O-ring on the water pipe side. Provides a weakened faucet.

According to the present invention, the flexible hose is pulled out before the rigid water pipe when the water discharge port is pulled out by a certain amount, and the operability is not impaired.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described more specifically with reference to the drawings. 1 to 5 show a state in which a hot and cold water mixing faucet equipped with a water discharge pipe portion according to an embodiment of the present invention is used in a kitchen as an example of a water supply facility.

A hot and cold water mixing plug 3 having a hot and cold water mixing portion 1 and a water discharge pipe portion 2 supplies water or hot water to a washing area K of the kitchen and is fixed to the counter surface of the kitchen as shown in FIG. .

The hot and cold water mixing tap 3 has a hot and cold water mixing portion 1 as shown in FIG. 2, and a valve is provided inside the hot and cold water mixing portion 1 to operate the operating handle 5 to discharge water, stop water, and mix hot and cold water. Can be adjusted. The water spout part 4 is provided at the tip of the water spout part 2.
Is connected so that it can be pulled out.

As shown in FIG. 2, a water pipe 10 having a flexible hose 6 therein in a watertight and slidable manner is incorporated in the water discharge pipe section 2 in a watertight and slidable manner. The water spout part 4 can be pulled out and used.

At both ends of the flexible hose 6, hose joints 7,
8 is fixed by a collar 9, one end of which is connected to the water outlet portion and the other end of which is connected to the water pipe 10 in a watertight and slidable manner. A stopper 12 that prevents the hose joint 7 from falling off from the tip is screwed to the tip of the water pipe 10.

A joint 11 is watertightly joined to the water pipe 10. Further, a ball joint portion 17 is connected to the joint 11 and is watertightly and slidably connected to the water discharge pipe 2a. With this, because the bent portion is configured on the proximal end side of the water pipe,
The water pipe 10 can be freely bent when pulled out. In this embodiment, an example of a ball joint is shown, but a bendable member such as a flexible hose may be used to form the bend portion. At the tip of the water discharge pipe 2a, a bush 13 having a stopper function for preventing the water passage pipe 10 from falling off the tip and holding the water discharge port detachably is fixed by a screw 14.

The usability is improved by controlling the drawing order of the flexible hose 6 and the water pipe 10.
For example, the tightening margin of the O-ring 15 that keeps the flexible hose 6 watertight is set to be weaker than the tightening margin of the O-ring 16 that keeps the water pipe 10 watertight. As a result, when the user pulls out the spout 4, the flexible hose 6 is pulled out first,
Further, when the user pulls the spout 4, the flexible hose 6 hits the stopper 12 so that the water pipe 10
Is withdrawn. That is, when the water spout portion 4 is slightly pulled out, the flexible hose 6 that can be bent is always pulled out, and water can be spouted over a wide range of a kitchen sink, for example, so that operability is not impaired.

Further, the flexible hose 6 may be withdrawn after the water pipe 10 is first withdrawn. For example, when water is stored in a deep pan or the like and the water spout portion 4 is to be arranged at a slightly higher position to spout water, a larger space is created between the kitchen sink and the water spout portion, so that the deep pan is spouted. It can be said that it is very convenient because the water spout 4 of the faucet does not get in the way when it is inserted below the water spout.

In FIG. 5, a joint 11 joined to the water pipe 10 is connected to the water discharge pipe 2a in a watertight and slidable manner. With this, the drawer length can be further lengthened,
For example, it is an effective method for a faucet with a wall.

In FIG. 6, the stopper 18 prevents the water spout portion 4 from falling off the tip of the water spout pipe 2a at high water pressure.
Is provided on the bush 13. This stopper 18 is shown in FIG.
FIG. The water discharge port 4 has a convex portion 4a at the base portion and is inserted into the fitting portion 13a of the bush 13.
The bush 13 has a groove 13b through which a stopper 18 can slide in the radial direction. The stopper 18 has a stretchable spring-like fin 18a integrally formed. When the water outlet is stored, the convex portion 4a of the water outlet portion 4 is inserted into the fitting portion 13a of the bush 13 and the stopper 18 is caught by the convex portion 4a to prevent the water outlet portion 4 from falling off. When pulling out the spout 4, the stopper 18 is moved in the radial direction to move the protrusion 4a.
It is necessary to cancel the interference between the stopper 18 and the stopper 18.

In the examples, the mixed faucet used in general households was mentioned, but the discharge pipe part of the present invention is not limited to the mixed faucet,
It can also be used for a faucet having a discharge pipe part such as an industrial facility using a fluid, a kitchen facility, a medical facility.

[0021]

The present invention has the following effects due to the above configuration. According to claim 1, the shower hose connected to the water spout does not occupy the space under the counter, and in the faucet of the type in which the shower hose is built in the water discharge pipe, the withdrawal length is increased. By doing so, it is possible to provide a faucet having a water discharge pipe portion with improved convenience and operability. According to the second and third aspects, it is possible to provide a water faucet having a water discharge pipe portion whose convenience and operability are further improved.
