Description

[Detailed explanation of the invention] This invention relates to a water-saving device, and its main purpose is to prevent water-saving devices from being easily removed by users, in other words, by amateurs.
The purpose is to provide a water-saving device that can automatically achieve the purpose of water-saving within a range that does not cause any problem in actual use, and the other purpose is to generate less noise so as not to cause any inconvenience to the user. To provide a water-saving device that does not require hanging and can be provided at low cost by applying a colander.

Conventionally, it has been known to incorporate water-saving parts into faucets and the like for the purpose of water-saving, but the known water-saving parts are, in layman's terms, attached to a position where the end user can easily replace them. Therefore, there is a drawback that the supplier cannot achieve the desired water saving effect by replacing the parts.

Another drawback was that the water-saving parts generated noise.

This idea was devised in view of these points.The main point of this idea is to incorporate a flow restriction plate with multiple small-diameter through holes inside the colander to supply the amount of water required by the user. In addition, the water saving purpose can be achieved automatically by restricting the amount of water that is more than necessary, the noise is low so that it does not disturb users, and the product can be provided at a low cost. This is a characteristic feature.

Next, an embodiment of the water-saving device according to the present invention will be described based on the drawings.

1 is a colander, and the colander 1 has a large diameter part 2 and a small diameter part 3.
It is formed of a stepped cylindrical member made of rust-proof material such as brass, hard alloy, or resin.

Further, an internal thread 4 is provided on the inner circumferential surface of the large diameter portion 2, and an external thread 5 is provided on the outer circumferential surface of the small diameter portion 3, respectively.

Further, 6 is a flow rate restricting plate made of the same rust-free material as described above and having a thickness of about 6 mm, and having a plurality of small diameter through holes 7, such as 4 to 6, formed at appropriate intervals. The outer peripheral surface of the limiting plate 6 is formed with an outer thread 8 which is screwed into the inner thread 4.

However, the flow rate restricting plate 6 configured as described above can be freely attached and detached by screwing the outer thread 8 to the inner thread 4 of the colander 1.
It is fixed within the large diameter portion 2 of the colander 1.

However, if the diameter of the flow rate restriction plate 6 is, for example, about 21 mm,
When forming four small diameter through holes 7 as shown in FIG.
The diameter of the through holes 7 is about 2 mm, and they are formed at equal intervals on a concentric imaginary circle drawn by an imaginary line on the center point of the radial length of the flow rate restricting plate 6.

When the diameter of the flow restriction plate 6 is about 21 mm and five small diameter through holes 7 are formed as shown in FIG. 3, the diameter of the small diameter through holes 7 is about 1.5 mm. One piece is provided, and the remaining four pieces are formed at equal intervals on an imaginary circle drawn by an imaginary line on the center point of the radial length of the restriction plate 6.

Further, when the diameter of the flow rate restricting plate 6 is approximately 21 mm as described above and six small diameter through holes 7 are formed as shown in FIG.
The diameter of the through hole 7 is 1.5 mm, and one hole is provided at the center of the flow rate restriction plate 6, and on an imaginary circle drawn with an imaginary line on the center point of the radial length of the restriction plate 60, The remaining five pieces are formed at equal intervals.

The water-saving device of the present invention is constructed as described above and is used in the same manner as a conventional colander.

That is, as shown in FIG. 5, a water supply pipe b is installed in a fixed body such as a wall a.
is buried in the vertical direction, and the direction of the water supply pipe b is changed to the horizontal direction,
Depending on the thickness of the wall a, the water-saving device of the present invention is embedded and fixed in the wall a by connecting the outer screw 5 and the inner screw 4 so that the length is approximately the same as the thickness of the wall a, and the water-saving device is fixed at the tip thereof. A valve d provided in the cylinder C is opened and closed to drain or stop the tap water.

That is, the water-saving device of the present invention is used by being embedded in a fixed body such as the wall a, as described above.

Next, the effects will be explained.

The water-saving device of the present invention has a flow rate limiting plate 6 screwed and fixed into a colander 1, and is buried in a fixed body such as a wall a like a conventional colander. Since the restriction plate 6 cannot be removed, the purpose of saving water can be automatically achieved while ensuring the required amount of water supply.

In addition, the flow rate restriction plate 6 provides resistance to the tap water and reduces the pressure of the tap water, so even if valve d is fully opened, the excessive flow of tap water can be reduced and the purpose of water conservation can be achieved. be.

Furthermore, since the flow rate restricting plate 6 provides resistance to the tap water as described above, noise is generated when the resistance occurs, but this noise is absorbed by the wall a and does not bother the users.

In addition, since a large number of small-diameter through holes 7 are formed in the flow rate restriction plate 6, the results are shown in the table below compared to when one through hole with a cross-sectional area equal to the total cross-sectional area of the small-diameter through-holes 7 is formed. As shown, less noise is generated.

However, the above volume indicates the volume at a position of about 10 cm.

Moreover, since it has a simple structure in which the flow rate restricting plate 6 is screwed and fixed inside the colander 1, it is easy to manufacture and can be provided at low cost.

As is clear from the above explanation, the proposed water-saving device was designed as described above and was able to automatically achieve the water-saving purpose desired by the supplier while supplying the necessary water to the user. be.

Furthermore, it generates little noise and does not cause any inconvenience to users.

Moreover, it can be provided at low cost.
