Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a faucet that is attached to a water faucet and is used to obtain a shower-like water discharge.

[Background Art] A faucet that is attached to a faucet 10 and discharges water from the faucet 10 in a shower-like manner includes a water discharge plate 4 in which a large number of small holes 42 are formed, as shown in FIG. By guiding water from the faucet 10 into these small holes 42 and discharging the water, a shower-like water discharge is performed. The direction is perpendicular to the surface of the water discharge plate 4, and therefore, in the flat water discharge plate 4, the spread of shower-like water is small. However, when washing dishes, etc., there is a demand for a device that can spray water over a large area. As shown by the imaginary line in Figure 8, if the water discharge plate 4 is made to have a bulge and a spherical shape, it will be possible to discharge water in a wide, shower-like manner, but this will increase the height of the faucet. When used by being attached to the tip of the faucet 10, an increase in height causes various problems and is not preferable.

[Object of the Invention] The present invention has been made in view of the above points, and its object is to provide a water faucet that can discharge water in a wide shower-like manner even from a flat water discharge plate.

[Disclosure of the Invention] Accordingly, the present invention provides a water faucet in which a water discharge plate is provided with a large number of small holes for discharging water in the form of a shower, in which the outer peripheral side of the water discharge plate at the tip opening of each small hole is on the inner peripheral surface of the small hole. It is characterized by having a continuous inclined surface, and the center side of the water discharge plate at the tip opening of each small hole is a stepped part that is continuous with the inner peripheral surface of the small hole via a step, and the water passing through the small hole is By flowing the water along the slope,
The flow is designed to spread toward the outer periphery of the water discharge plate.

The present invention will be described in detail below based on the illustrated embodiment. This faucet includes a main body 1 made of synthetic resin and formed into a cylindrical shape with vertical openings, a mounting nut 63 attached to the upper part of the main body 1, and a main body 1. A disc-shaped water discharge plate 4 attached to the bottom surface of the main body 1
It is composed of a cylindrical rotary type valve 5 housed inside the main body 1, and an inlet 1 of the main body 1.
The upper end where numeral 1 is formed in the center constitutes a mounting portion for mounting to the water faucet 10 with the mounting nut 63 mentioned above. An inner cylinder 61 that surrounds the inlet 11 and an outer cylinder 62 that further surrounds this are erected on the upper surface of the main body 1. A water stopper 12 is disposed inside the inner cylinder 61, and the outer cylinder A male thread is cut on the outer peripheral surface of 62 to be screwed into the mounting nut 63.
The main body 1 is attached to the faucet 10 by inserting the tip of the faucet 10 into the inner tube 61, screwing the mounting nut 63 into the outer tube 62, and pressing the tip of the faucet 10 against the gasket 12 using the auxiliary fixture 64. .

The center of the main body 1 is formed as a valve chamber 13 having a circular longitudinal section and opening on one side. This valve chamber 1
Reference numeral 3 denotes a part in which the valve 5 is housed, which opens upward through the inlet 11, and has a first outlet 14 and a second outlet 15 diagonally downward, respectively. Further, a cylindrical portion 18 surrounding the first outlet 14 is formed to hang down.

The water spout 4 attached to the lower surface of the main body 1 has a water spout 41 in the center and a large number of small holes 42 around the periphery for discharging water in a shower shape.
It is attached to the main body 1 by screwing it into a male thread formed on the lower end circumference of the main body 1. At this time, a ring-shaped partition member 45 is disposed between the water discharge plate 4 and the cylindrical portion 18 surrounding the first outlet 14 in the valve chamber 13 . This partition member 45 connects the flow path from the first outlet 14 to the water outlet 41 to the valve chamber 13 in the main body 1.
and is partitioned off from the external space of the cylindrical portion 18.

In the valve 5 housed in the valve chamber 13, the lower end of a thin cylindrical hanging piece 50 hanging down from the packing 12 along the inlet 11 comes into elastic contact with the outer peripheral surface. A flow path with both ends open is formed through the outer circumferential surface. This flow path has an inlet 53 with a large opening diameter at one end and an outlet 55 with a small opening diameter at the other end.

However, in the lever faucet, water is stopped when the inlet 53 of the valve 5 is not aligned with the lower end opening of the hanging piece 50 of the gasket 12, as shown in FIG. Valve 5 as shown in
When the inlet 53 is communicated with the inlet 11 and the outlet 55 is communicated with the second outlet 15 at the same time, the water from the inlet 11 is transferred to the outlet 55 and the second outlet.
After passing through the outlet 15 and hitting the upper surface of the ring-shaped partition member 45, the particles are scattered, and then the small holes 4 of the water discharge plate 4 are scattered.
2 is released in a shower-like flow. Furthermore, as shown in FIG. 7c, the inlet 5 in the valve 5
3 as the inlet 11, and the outlet 55 as the first outlet 14.
When these are connected to each other, water from the inlet 11 flows to the first outlet 14 located directly below it, and is discharged from the water outlet 41.

Now, as is clear from the above, when performing a shower-like water discharge, water is released from the small hole 42 of the water discharge plate 4, and the small hole 42 here is As shown in FIG. 2, its cross section is not constant, but the diameter of the opening on the tip side is widened in the radial direction of the water discharge plate 4 due to the sloped surface 43 and the stepped portion 44, so that the cross-sectional area is increased. , the sloped surface 43 whose upper end is continuous with the inner peripheral surface of the small hole 42 is on the outer peripheral side of the water discharge plate 4 in each small hole 42, and the step part 44 which is continuous with the inner peripheral surface of the small hole 42 via a step is the water discharge plate. It is provided on the center side of 4. For this reason, the water flowing down the small hole 42 is
All of the water flows along the slope 43 that is directly continuous with the inner circumferential surface of the small hole 42, and therefore all of the water that comes out of the small hole 42 flows toward the outer circumference of the water discharge plate 4 and spreads. This allows you to obtain a shower-like water discharge.

The step portion 44 in each small hole 42 may be formed by an annular groove 46 provided on the lower surface of the water discharge plate 4, as shown in FIGS. 3 and 4.

Other embodiments are shown in FIGS. 5 and 6. The water discharge plate 4 is formed of a substrate 4A in which a small hole 42 having a constant diameter is provided, a plate 4B detachably and rotatably attached to the lower surface of the substrate 4A, and an inclined surface 43. The step portion 44 is formed on the plate 4B side. If the plate 4B is attached, a wide shower-like water discharge can be obtained by the water flowing along the slope 43, and if the plate 4B is removed, a shower-like water discharge without spreading can be obtained. The plate 4B has each small hole 4 of the substrate 4A.
2, and an inclined surface 43 and a stepped portion 44 at one end of the long hole 40.
Since a hole with a larger diameter than the small hole in the substrate 4A is provided at the other end, when the plate 4B is rotated so that the small hole 42 is connected to the inclined surface 43, the expansion will be reduced. When a small hole 42 is located in a hole with a large diameter at one end of the elongated hole 40, as shown by the dotted line in FIG. 6, a shower-like water discharge without spreading can be obtained. . In other words, the shower pattern can be changed. Plate 4 with different slope angles of slope 43
B may be prepared in several types, or the inclined surface 43 formed on one side wall of the elongated hole 40 may have an inclination angle that is different from that of the elongated hole 40.
By making the shower pattern gradually change in the long diameter direction, more types of shower patterns can be obtained. By changing the inclination angle and inclination direction of the inclined surface 43 for each small hole 42, the shape of the water spray from the shower can be made circular, elliptical, or angular.

Although the illustrated example shows a device that can also stop water, it may also be possible to switch only between direct water discharge from the water outlet 41 and shower-like water discharge, or even only a shower-like water discharge. Of course, it is okay if you cannot do it.

[Effects of the Invention] As described above, in the present invention, by controlling the direction of the flow of water flowing down the small hole using the stepped portion and the inclined surface, the flow direction of the water flowing down the small hole is controlled, so that the direction of the flow of water flowing down the small hole is controlled. This allows for a shower-like water discharge that is spread out and easy to use without having to make the water discharge plate bulge, that is, without increasing the height of the faucet.
