The faucet 2 is not limited to the single lever type, and any other type of faucet may be used as long as it has a function of switching between water discharge / stop of the water discharge unit 6. Further, the form of the faucet 2 shown in FIGS. 1 and 2 is an example, and the specifications and the like of the spout main body portion 4 and the operation portion 8 may be appropriately changed.

In the faucet 2 of this embodiment, the structure of the water discharge portion 6 is devised. Although the water discharge unit 6 is schematically shown in FIGS. 1 and 2, the detailed structure of the water discharge unit 6 will be described with reference to FIGS. 3 and later.

FIG. 3 is a vertical sectional view showing the tip end side of the water discharge portion 6. As shown in FIG. 3, the water discharge unit 6 includes a first cylindrical member 10, a second tubular member 12, and a water discharge member 14.

The first cylindrical member 10 forms the first internal flow path 16 inside, and the second tubular member 12 forms the second internal flow path 18 inside. The first internal flow path 16 is a space formed between the first cylindrical member 10 and the second tubular member 12. In FIG. 3, the flow of water in the first internal flow path 16 and the second internal flow path 18 is indicated by an arrow.

The inclined surface 25 is a surface extending in the circumferential direction R centered on the axial direction A as an outer peripheral surface of the water discharge member 14. The inclined surface 25 connects one end 22 and the other end 24, and is inclined so as to spread outward from one end 22 toward the other end 24. The inclined surface 25 of the present embodiment extends all around the circumferential direction R and is connected in an annular shape.

As shown in FIG. 3, when the water discharge member 14 is attached to the second tubular member 12, one end 22 of the water discharge member 14 is inserted into the first internal flow path 16 from the opening 26 of the first tubular member 10. .. In a state where the water discharge member 14 is positioned by screwing with the second tubular member 12, the inner edge portion 28 of the first tubular member 10 forming the opening 26 and the inclined surface 25 face each other and leave a gap between them. ing.

The water flowing through the first internal flow path 16 flows along the inclined surface 25 of the water discharge member 14 so as to pass through the gap between the inner edge portion 28 and the inclined surface 25, and is separated from the end portion 30 of the inclined surface 25. Water is spit out. As a result, an annular water discharge flow S1 is formed.

The plurality of recesses 32 are regularly arranged along the circumferential direction R of the water discharge member 14. As shown in FIG. 6, the recesses 32 of the present embodiment are arranged at substantially equal intervals over the entire circumference in the circumferential direction R.

By arranging the plurality of recesses 32, a desired uneven pattern can be formed on the surface of the water discharge flow S1 when the water discharge flow S1 flowing along the inclined surface 25 forms an annular water film.

FIG. 7 shows an image of the water discharge flow S1. As shown in FIG. 7, the water discharge stream S1 forms a texture pattern on the surface as a predetermined uneven pattern. Such a texture pattern appears when the ridges 34 extending diagonally from each end of the recess 32 intersect with each other. In this way, it is possible to realize an unusual water discharge form.

Further, the detailed shape of the recess 32 will be described with reference to FIGS. 8 to 10.

As shown in FIG. 8, each of the recesses 32 has a width W along the circumferential direction R. The recess 32 of the present embodiment has a shape in which the width W gradually increases from the upstream to the downstream in the flow direction F. According to such a shape, the water flowing along the recess 32 is diverged outward to generate a rotation component in the circumferential direction R in the water discharge flow S1, and a desired texture pattern can be formed in the water discharge flow S1.

Further, in the present embodiment, as shown in FIG. 8, the ridgeline of the recess 32 has a smooth curved shape. The gradual increase rate of the width W of the recess 32 decreases from the upstream to the downstream in the flow direction F.

As shown in FIG. 9, the cross-sectional shape of the recess 32 is a smoothly curved arc shape. The lowest point 34 is located at the center position of the recess 32 in the width direction P. The recess 32 is formed by a shape in which such an arcuate cross-sectional shape is continuous in the flow direction F.

By making the cross-sectional shape of the recess 32 a smooth arc shape, it is possible to reduce the flow path resistance to the water flowing along the recess 32, and it is possible to stably form the texture pattern of the water discharge flow S1.

According to such a configuration, when the concave portion 32 is formed by shaving or the like, the concave portion 32 can be formed with the lowest point 34 as a reference, and the concave portion 32 can be easily formed with less shape error. ..

As shown in FIG. 10, the recess 32 has a shape in which the maximum depth D1 at the lowest point 34 gradually increases along the flow direction F. As a result, with respect to the water flowing along the recess 32, the velocity component traveling inward toward the center of the water discharge member 14 becomes large, and the shape of the water discharge flow S1 becomes more three-dimensional. As a result, a desired texture pattern can be formed on the water discharge flow S1, and the visibility of the water discharge form different from the usual one is also improved.

In this embodiment, the angle θ is set to 150 degrees or more and 175 degrees or less. As a result, with respect to the water flowing along the recess 32, the velocity component advancing inward toward the center of the water discharge member 14 can be appropriately increased, and a desired texture pattern can be formed in the water discharge flow S1.

Further, in the faucet 2 of the present embodiment, in addition to the water discharge flow S1 having the texture pattern described above, a straight water discharge flow S2 is combined. As a result, the practicality of the faucet 2 can be improved while realizing a water discharge form different from the usual one.
