DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water faucet pipe having a flow path bent near a water spout.

[0002]

2. Description of the Related Art A water tap is provided with a water discharge pipe for discharging water or mixed hot and cold water (hereinafter simply referred to as fluid). The water discharge pipe has a shape protruding from the water faucet main body and having a tip bent downward.
It is common to have a bent channel near the water outlet.

[0003]

However, in the conventional water discharge pipe, as shown in FIG. 4A, the flow direction of the fluid is rapidly changed by a bent portion near the water discharge port, so There was a problem that the flow velocity was faster on the front side of the water port than on the rear side, and the water discharge from the water discharge port was inclined forward, so that uniform cylindrical water discharge could not be obtained. In particular, when the internal flow path is narrow or the water supply pressure is high, or when the flow path bends sharply and largely, the above-mentioned problem has occurred remarkably.

Meanwhile, as a technique for solving this problem, there is a technique disclosed in Japanese Patent Application Laid-Open No. 3-275824. In this case, as shown in FIG. 4B, a guide plate is provided in the flow path at the bent portion along the bending direction to guide the fluid directly below the water discharge port. However, according to such a guide plate, the water discharge is divided into several layers in the front-rear direction, and it is not possible to obtain ideal uniform columnar water discharge. In addition, since the flow velocity is higher at the front side of the water discharge port, the flow rate is larger at the front side of the divided layer,
A difference in flow rate occurs in the front-rear direction of the water outlet, and uniform water cannot be obtained over the entire water outlet.

The present invention has been made to solve such a problem, and an object of the present invention is to obtain uniform cylindrical water discharge from a water discharge port. Especially,
An object of the invention of claim 2 is to further uniform the flow rate in the front-rear direction of the water discharge port and to simplify the structure. Another object of the present invention is to provide a uniform water discharge pipe even in a water discharge pipe in which the flow path is largely bent in the vicinity of the water discharge port and the water discharge is likely to be uneven. And

[0006]

Means taken to solve the above problems by means of the present invention will be described with reference to the reference numerals used in the drawings. 2
In the water faucet 10 of the water faucet having a flow path bent near zero, the flow rectifying section 30 for guiding the fluid in the direction of the water discharge port is provided in the flow path of the bent portion through the gap 40 between the flow path and the side surface 11 of the flow path. And a water faucet 10 of a water faucet.

In the present invention, the rectifying section 30 for guiding the fluid in the flow channel toward the water discharge port 20 is provided, so that the water discharge port 20 is provided.
In addition to achieving uniform discharge of water from the water, by providing a gap 40 between the rectifying unit 30 and the side surface 11 of the flow path, the fluid can flow toward the tip of the water discharge pipe 10 from the rectifying unit 30. . Accordingly, the fluid is not divided between the rear side and the front side of the rectification unit 30, and the water discharged from the water discharge port 20 has an ideal uniform cylindrical shape without forming a layer divided before and after. Become.

Next, a second aspect of the present invention relates to the “rectifying section 3.

In the present invention, the rectifying section 30 is provided on the upper surface 12 of the flow path.
, And the upper part of the rectifying part 30 is connected to the upper surface of the flow path. Accordingly, the fluid does not flow from above the straightening unit 30 and is not divided by the straightening unit 30, and the variation in the flow rate of the water discharged from the water discharge port 20 in the front-rear direction can be further suppressed. Further, by making the flow straightening portion 30 a hanging body, for example, the flow straightening portion 30 can be formed integrally with the water discharge pipe 10, and the structure can be simplified.

Finally, a third aspect of the present invention is "a spout 10 for a water tap according to the first or second aspect, wherein the angle of the bent portion is an acute angle."

The present invention is based on the assumption that the angle of the bent portion is an acute angle, that is, an angle of less than 90 °, and the water discharge tube 10 in which the problem of non-uniform water discharge becomes prominent. Even so, it is possible to obtain ideal uniform columnar water discharge.

Next, embodiments of the present invention will be described.
This will be described in detail with reference to the drawings. FIG. 1 shows an example of an embodiment of the present invention. The water discharge pipe 10 protrudes from a main body of a water faucet (not shown) such as a single water faucet connected to a water supply pipe to discharge water, or a hot water mixing faucet connected to a water supply pipe and a hot water supply pipe to discharge mixed hot and cold water. Have been. The distal end of the water discharge pipe 10 is bent and suspended, and a water discharge port 20 communicating with a flow path inside the water discharge pipe 10 is provided on the lower surface of the suspended part.

The flow passage inside the water discharge pipe 10 is bent at an acute angle in the vicinity of the water discharge port 20 as in the third aspect of the present invention. A rectifying section 30 for guiding the water to the water outlet 20 is provided. Also,
The side surface 1 of the flow path of the water discharge pipe 10 is located on the side of the rectifying section 30.
A gap 40 through which a fluid can flow is formed between the gap 40 and the gap 1. Here, in the present embodiment, the rectifying section 30 is provided so as to hang down from the upper surface 12 of the flow channel, and is formed integrally with the water discharge pipe 10.
The shape is a flat plate that intersects at a substantially right angle to the flow path direction. With the rectifying unit 30 having such a configuration, the fluid (a) in the center of the flow path of the water discharge pipe 10 collides with the rectifying unit 30 from the front, is guided to the lower water outlet 20, and is located behind the water outlet 20. A part of the fluid (b) on both sides of the flow path flows from the side of the flow straightening unit 30 to the water discharge port 20, and the remaining part passes through the gap 40 and is on the tip side of the water discharge pipe 10. And water is discharged from the side and the front side of the water discharge port 20, respectively. Therefore, the water discharge as the whole water discharge port 20 has an ideal uniform cylindrical shape without being divided in the front-rear direction.

In this embodiment, the rectifying portion 30 is formed in a flat plate shape. However, the present invention is not limited to this. For example, the rectifying portion 30 may be formed in a curved plate shape, a cylindrical shape, or the like. 20
And a gap may be formed between the water discharge pipe 10 and the side surface 11 of the flow path. The rectification unit 3
In the case where 0 is formed in a columnar shape, as shown in FIG. 2A, the communication hole 31 is formed in a substantially cylindrical shape and communicates with the internal space.
Should be provided. In this case, the fluid (a) that collides with the rectifying unit 30 from the front is discharged from the rear side of the water outlet 20, and the fluid on the side of the rectifying unit 30 and the fluid (b) that passes through the side are discharged from the water outlet, respectively. Water is spouted from the side and front side of 20,
Further, since the fluid (c) that has entered the internal space of the cylindrical rectifying portion 30 from the communication port 31 is discharged from the central portion of the water discharge port 20, more ideal uniform columnar water discharge can be obtained. Further, as shown in FIG. 2B, the rectifying unit 30 may be formed in a spiral shape, and one of the sides of the rectifying unit 30 may be connected to the side surface 11 of the flow path of the water discharge pipe 10. In this case, the fluid (a) that collides with the rectifying unit 30 from the front is discharged from the rear of the water discharge port 20, and the fluid on one side of the rectifying unit 30 and the fluid passing through the one side are partially ( B) spout 2
0 is discharged from one side and the front side, and the other part (c) is guided to the other side and the center part of the water discharge port 20 by the spiral rectifying part 30 and discharged, and a vortex is formed in the water discharge. As a result, a more ideal and uniform cylindrical water discharge can be obtained.

The embodiments of the present invention have been described above. However, the present invention is not limited to the embodiments, and may be appropriately changed without departing from the gist of the present invention. For example, in the first and second aspects of the present invention, the water discharge pipe is not limited to the water discharge pipe 10 having a flow path bent at an acute angle, but may be a water discharge pipe having a flow path bent at 90 ° or an obtuse angle. Further, in the first and third aspects of the present invention, the rectifying section 30 is not limited to the one that hangs down from the upper surface 12 of the flow path. Cap 50 formed on
For example, a flat rectifying section 30 is provided in the
And a water discharge pipe 10 having a rectifying section 30 as shown in FIG. In this case, the rectifying unit 30 may be disposed such that the upper end of the rectifying unit is in contact with the upper surface 12 of the flow path or a small gap is formed. This is because, when the gap between the upper end of the rectifying unit 30 and the upper surface 12 of the flow path is large, the fluid from above the rectifying unit 30 is separated by the rectifying unit 30 and the water discharge is likely to be a layer in which water is separated back and forth. This is because it becomes impossible to reliably obtain uniform cylindrical water discharge.

Further, according to the present invention, the fluid in the water discharge pipe 10 can be rectified and can be used without any device attached to the water discharge port 20.
A well-known rectifying plate formed by winding a stainless steel thin plate material into a corrugated shape and winding it into a star shape, or a well-known rectifying plate formed by forming a net with a thin stainless steel wire material at the water discharge port 20. A net or the like may be attached.
