BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flow straightening plate for a water spout, and more particularly to a flow straightening plate for a water spout which is mounted on a water spout of a faucet via a case to straighten the water discharge.

[0002]

2. Description of the Related Art FIG. 3 is a side view showing a faucet.

As shown in FIG. 3, the water discharge port 2 of a water faucet 1 such as a mixed water faucet in a bathroom is in a normal state in which nothing is attached, and the water discharge flow rate becomes excessive at the time of opening the water discharge flow. There is a possibility that water may be scattered and water may be dripped from the water discharge port 2 even after the water is closed and closed. Therefore, normally, in order to prevent the discharge flow rate from becoming excessively large, a flow resistance is applied to the discharge flow to perform rectification,
In addition, a rectifying plate is attached to the water discharge port 2 for the purpose of preventing the dripping of water after stopping the water by utilizing the surface tension.

As a conventional straightening plate of this type, there is a technique shown in FIG. FIG. 4 is an exploded perspective view showing a conventional flow straightening plate for a water discharge port together with a case.

In FIG. 4, the current plate 51 is attached to the water outlet 2 of the faucet 1 by a case 52. The current plate 51 is made of stainless steel (SUS) and has a disk shape having a diameter corresponding to the inner diameter of the water discharge port 2, and the inside thereof is a fine mesh portion 51a. On the other hand, the case 52 is formed of a synthetic resin in a substantially cylindrical shape, and has a flange 52a protruding inward at the lower end, and the inner periphery of the flange 52a is formed as an opening 52b for ejecting a discharge water on the flange 52a. Two plates 51 are stacked and placed. In addition, the case 52 is
A female screw 52c corresponding to the male screw 2a on the outer circumference of the water outlet 2 is threaded, and the female screw 52c is screwed onto the male screw 2a of the water outlet 2 to be attached to the water outlet 2 of the faucet 1.

Next, the operation of the conventional flow straightening plate 51 constructed as described above will be described.

[0007] In the state where the two straightening vanes 51 are arranged in the case 52 and the case 52 is screwed and attached to the water discharge port 2,
When the faucet 1 is opened, the water discharge flow from the water discharge port 2 sequentially passes through the mesh portions 51a of the two flow rectifying plates 51 in the case 52 and is ejected from the opening 52b at the lower end of the case 52.
At this time, the water discharge flow from the water discharge port 2 is rectified by the flow resistance of the mesh portion 51a of the rectifying plate 51, preventing the flow rate from becoming excessive, and as shown in FIG. It is ejected from the opening 52b without scattering. In addition, after closing the faucet 1, the mesh portion 51a of the rectifying plate 51 has a fine mesh shape, so that the water remaining in the spout 2 is retained by surface tension, and due to its draining effect, from the lower end of the case 52. Prevent dripping of water.

[0008]

The conventional rectifying plate 51 is
As described above, in order to rectify the water discharge, the case 52
Since two sheets are arranged in the inside, there is a possibility that the number of parts as a whole is increased and the cost is increased. Further, when the water discharge port 2 is assembled, there is a possibility that one of the rectifying plates 51 may be forgotten to be mounted in the case 52 and a stockout may occur. In this case, one rectifying plate 51 cannot be expected to have a sufficient rectifying effect and a draining effect, and the rectifying plate 51 and the case 52 to the water discharge port 2 cannot be expected.
It is inconvenient because the reassembling work is required. Further, since the mesh portion 51a of the straightening vane 51 has a fine mesh shape, the mesh portion 51a may be clogged. In this case, extra work such as cleaning or replacement of the straightening vane 51 is required, which is troublesome. Is.

Therefore, an object of the present invention is to provide a flow straightening plate for a water outlet that does not cause a shortage during assembly and does not cause problems such as clogging during use.

[0010]

A water flow straightening plate according to the present invention is made of a synthetic resin having a predetermined height extending in a water discharge direction inside a synthetic resin outer shell having an outer shape corresponding to the inner circumference of the water spout. The plate-shaped ribs are arranged so as to intersect with each other, and a large number of straightening holes having a predetermined plane shape are formed.

[0011]

In the present invention, when water is spouted from the spout while the straightening vane is attached to the spout, the spouted water from the spout passes through the straightening hole of the straightening plate and follows the plate-shaped rib. It is guided downward and ejected. Therefore, the water discharge flow from the water discharge port is provided with the water flow resistance by the ribs, and the flow rate thereof is appropriately controlled and rectified, so that the water flow is not scattered and ejected from the water discharge port. Further, after the plug is closed, the water remaining in the spout will stay on the surface of the rib due to the surface tension and will not drip downward.

EXAMPLES Examples of the present invention will be described below.

FIG. 1 is an exploded perspective view showing a flow straightening plate for a water outlet according to an embodiment of the present invention together with a case, FIG. 2 shows a flow straightening plate for a water outlet according to an embodiment of the present invention, and FIG. , (B)
Is a sectional view.

It should be noted that, in the drawings, the same reference numerals and symbols as those of the conventional example indicate the same or corresponding parts as those of the conventional example, and therefore, redundant description will be omitted here.

In the figure, the current plate 10 of the present embodiment is one in which ribs 12 are integrally formed in the outer shell 11 of a predetermined synthetic resin, and like the conventional example, the water discharge port 2 of the faucet 1 is formed by the case 52. It is attached to. The outer shell 11
Is formed in a short cylindrical shape having a substantially same outer shape as the lower end of the water discharge port 2 and a predetermined height. The rib 12 includes a plurality of radiating portions 12a extending in the outer shell 11 in the radial direction and a circumferential portion 12b extending in the outer shell 11 in the circumferential direction and connecting the radiating portions 12a. A large number of straightening holes 13 having a predetermined plane shape, such as a substantially triangular shape and a substantially square shape, are formed in the outer shell 11 so as to intersect the peripheral portion 12b. Rib 1
The second radiating portion 12a and the circumferential portion 12b are formed in a plate shape that extends in the water discharge direction at the same height as the outer shell 11.

The height of the current plate 10, that is, the height of the outer shell 11 and the rib 12 is the same as that of the water outlet 2 of the faucet 1 to be used.
According to the type of, etc., it is determined to a value that can maintain the water flow resistance moderately and achieve the desired rectifying effect and draining effect,
In the case of a normal faucet 1, it is preferable to set it to about 3 mm. If the height of the straightening vanes 10 is too large, the water flow resistance may become excessive, and it may not be possible to obtain a desired discharge flow, while if the height of the straightening vanes 10 is too small,
If the water flow resistance becomes too small, the flow rate of discharged water becomes too large, and the degree of dispersion of the discharged water becomes large, it may not be possible to obtain a sufficient rectifying effect and draining effect. Further, from the same viewpoint, the number of the rectifying holes 13 formed by the ribs 12 in the outer shell 11 is also set to a number that can appropriately maintain the water flow resistance and achieve the desired rectifying effect and draining effect. That is, if the number of the rectifying holes 13 is too large, the water flow resistance may be excessive and a desired discharge flow may not be obtained.
If the number of the rectifying holes 13 is too small, it may not be possible to obtain a sufficient rectifying effect and draining effect.

Like the conventional example, the straightening vane 10 constructed as described above is inserted into the case 52 with the outer peripheral surface of the outer shell 11 in a substantially intimate state, and is placed on the flange 52a at the lower end. The ribs 12 in the outer shell 11 are arranged so as to face the water spout 2 via the.

Next, the operation of the straightening plate 10 of this embodiment having the above-mentioned structure will be described.

With one rectifying plate 10 arranged in the case 52 and the case 52 being screwed to the spout 2 and attached,
When the faucet 1 is opened, the water discharge flow from the water discharge port 2 passes through the flow regulating holes 13 formed by the ribs 12 of the flow regulating plate 10 in the case 52 and follows the plate-shaped rib 12 having a predetermined height. And is guided downward and ejected from the opening 52b at the lower end of the case 52. At this time, the flow of water discharged from the water discharge port 2 is the flow rectifying plate 10.
Due to the water flow resistance of the ribs 12, the flow rate is appropriately controlled and rectified, so that the opening 52 at the lower end of the case 52 is
It is not scattered and ejected from b. In addition, after the faucet 1 is closed, the water remaining in the spout 2 is caused by surface tension.
The rib 12 does not stay on the surface of the rib 12 of the straightening vane 10 and does not drip downward, and the rib 12 exerts a predetermined draining effect as in the conventional example, and prevents water from dripping from the lower end of the case 52.

As described above, the rectifying plate 10 of the above embodiment is
A rib 12 is integrally formed in the outer shell 11 with a predetermined synthetic resin. The outer shell 11 is formed into a short cylindrical shape having substantially the same outer shape as the lower end of the spout 2 and a predetermined height. Is formed into a plate shape extending in the water discharge direction at the same height as the outer shell 11, and a plurality of radial portions 12a extending in the outer shell 11 in the radial direction are connected to the radial portions 12a extending in the outer shell 11 in the circumferential direction. The radiating portion 1 is composed of a circumferential portion 12b.
2a and the circumferential portion 12b are crossed, and inside the outer shell 11,
A large number of straightening holes 13 having a predetermined plane shape such as a substantially triangular shape and a substantially square shape are formed.

Therefore, in the above embodiment, when water is discharged from the water discharge port 2 with the current plate 10 attached to the water discharge port 2 via the case 52, the water discharge flow from the water discharge port 2 becomes It passes through the flow regulating hole 13, is guided downward along the plate-shaped rib 12 and is ejected. Therefore, the water discharge flow from the water discharge port 2 is provided with water flow resistance by the ribs 12, the flow rate thereof is appropriately controlled and rectified, and thus is not scattered and ejected from the opening 52b at the lower end of the case 52. . Further, after the plug is closed, the water remaining in the water discharge port 2 stays on the surface of the rib 12 due to the surface tension and does not drip downward.

As a result, the rectifying plate 10 made of a synthetic resin, which is a single component, can achieve the same rectifying effect and draining effect as in the conventional example, reducing the number of parts, and
Costs can be reduced by preventing out-of-stock items. In addition, since the rectifying holes 13 do not have a thin mesh shape like the mesh portion 51a of the rectifying plate 51 of the conventional example, there is no problem such as clogging during use. Since the flow straightening plate 10 is integrally formed of synthetic resin, its manufacture is simple and its shape such as its height or the number of flow straightening holes 13 is easily changed according to the faucet 1 to be used. Since it can be manufactured in such a manner, it is possible to easily obtain the optimum rectifying effect and draining effect as needed. That is, by appropriately changing the height of the current plate 10 or the number of the current holes 13, it is possible to easily obtain the same effect as combining the desired number of metal current plates 51 of the conventional example.

By the way, the rib 12 of the above-mentioned embodiment is constructed so that the radiating portion 12a and the circumferential portion 12b are intersected with each other so as to obtain the straightening holes 13 having a flat shape such as a substantially triangular shape and a substantially square shape. However, the present invention is not limited to this, and may be any configuration that can rectify the flow of water discharged from the water discharge port 2 and can drain water after stopping water. For example, the ribs 12 are arranged in a lattice pattern in the outer shell 11,
Other arrangement configurations may be used. However, when the ribs 12 are arranged radially, the highest rectifying effect can be expected, and
The effect that the mold for manufacturing the current plate 10 can be easily manufactured is obtained.

Further, the outer shell 11 of the above-mentioned embodiment is provided with the spout 2
Although it is formed in a substantially short cylindrical shape corresponding to, and is formed at the same height as the rib 12, as long as it is mounted in the case 52 and can hold the rib 12 at a stable position with respect to the water outlet 2. Of course, other configurations such as a shape with a part of the circumferential direction omitted or a height different from that of the rib 12 can be adopted. However, when the outer shell 11 is formed into a substantially short cylindrical shape and has the same height as the rib 12, the effect of facilitating its manufacture is obtained.

The current plate 10 of the above embodiment is formed separately from the case 52, and is configured to be mounted inside the case 52 and attached to the water discharge port.
Is integrally formed on the lower end of the case 52, and
It is also possible to screw the female screw 52c on the upper part of 2 into the male screw 2a of the water discharge port 2. In this case, the current plate 10
Since both the case 52 and the case 52 are made of synthetic resin, they can be easily integrated, the number of parts can be further reduced, and the assembling workability and the cost can be further reduced.

Further, the outer shell 11 and the ribs 12 of the above embodiment.
Is formed in a plate shape that extends in the water discharge direction of the water discharge flow and is arranged parallel to the water discharge direction. However, by arranging this in a tapered shape that reduces the diameter downward, the water discharge flow is focused in the water discharge direction. It may be configured. In this case, since the discharged water flow can be focused and rectified, a sufficient rectifying effect can be expected even when the water pressure of the faucet 1 increases and the flow rate of the water discharged from the water discharge port 2 increases. Further, by appropriately changing the inclination angle of the ribs 12 and the like, it is possible to easily achieve the optimum rectifying effect and draining effect.

[0027]

As described above, the flow straightening plate of the water spout of the present invention is made of a synthetic resin having a predetermined height extending in the water spouting direction inside a synthetic resin outer shell having an outer shape corresponding to the inner circumference of the water spout. The plate-shaped ribs are arranged so as to intersect with each other, and a large number of straightening holes having a predetermined plane shape are formed.

Therefore, when water is discharged from the water outlet with the current plate attached to the water outlet, the water flow from the water outlet passes through the current holes of the current plate and moves downward along the plate-shaped rib. It is guided and ejected. Therefore, the water discharge flow from the water discharge port is provided with the water flow resistance by the ribs, and the flow rate thereof is appropriately controlled and rectified, so that the water flow is not scattered and ejected from the water discharge port. Further, after the plug is closed, the water remaining in the spout will stay on the surface of the rib due to the surface tension and will not drip downward. As a result, a rectifying effect and a draining effect can be achieved with a single component, the number of components can be reduced, and the occurrence of a shortage can be prevented to reduce the cost.
