  If comprised in this way, hot water will flow in, turning in a tangential direction with respect to a shower hole. For this reason, the hot water discharged from the shower hole spreads and becomes a mist. Further, the center axis of the shower hole is inclined with respect to the center axis of the face plate member so that the outer surface side of the face plate member is located on the outer peripheral side of the face plate member. For this reason, the direction of the hot water sprayed from the shower hole can be set obliquely in the outer peripheral direction of the face plate member. Therefore, the area of hot water sprayed as a shower on the skin can be increased, and the skin contact can be weakened. An annular restriction surface is formed around the outer end of the shower hole. Therefore, it can regulate so that the sprinkling range of hot water may not spread too much.

  According to the watering structure in the shower head of the present invention, the watering range of the shower can be widened, and the effect of being able to improve the feeling of use with gentle skin contact.

As shown in FIG. 6, an outer peripheral wall 171 is formed on the outer peripheral portion of the face plate member 17, and an inner peripheral wall 172 is formed inside the outer peripheral wall 171 with a space therebetween. As shown in FIGS. 6 and 7, an outer peripheral step 173 is formed on the inner peripheral side of the outer peripheral wall 171, and an inner peripheral step 174 is formed on the outer peripheral side of the inner peripheral wall 172. A flow path 175 is formed between 173 and 174. Between the inner and outer step portions 173 and 174, a plurality of shower holes 18 for sprinkling hot water are arranged in an annular shape on the face plate member 17 at regular intervals in the circumferential direction.

  As shown in FIGS. 6 and 7, a guide wall 176 for guiding hot water in the flow path 175 in the tangential direction of the shower hole 18 is formed in the outer peripheral step portion 173 and the inner peripheral step portion 174. . A hot water introduction part 19 is formed between the tip of the guide wall 176 and the outer peripheral step part 173 or the inner peripheral step part 174 facing the guide wall 176. Then, hot water from the flow path 175 flows while turning in the tangential direction (circumferential direction) with respect to the shower hole 18.

  As shown in FIGS. 3, 7, 9, and 10, the ring member 16 is placed on the outer peripheral step portion 173 and the inner peripheral step portion 174 and is pressed by the lid member 111 on the main body 11 side. Yes. The ring member 16 is made of a synthetic resin such as ABS resin. As shown in FIG. 8, the face plate member 17 side surface is provided with a gap 29 in the opening on the upstream side of each shower hole 18 to enter the conical section. The trapezoidal protrusions 20 are provided at regular intervals in the circumferential direction. As shown in FIG. 7, a hot water supply hole 21 for supplying hot water to the hot water introduction part 19 through the flow path 175 is opened between the protrusions 20, that is, between the shower holes 18.

  A plurality of positioning recesses 22 having an arc shape are formed on the outer peripheral surface of the ring member 16, and the ring member 16 is engaged with a plurality of positioning protrusions 23 provided on the inner peripheral surface of the outer peripheral wall 171. It is positioned and fixed to the face plate member 17.

  As shown in FIGS. 6 and 8, the shower hole 18 is formed in a tapered shape that becomes narrower toward the outer surface side of the face plate member 17. In addition, the shower hole 18 is inclined such that the center axis x thereof is positioned on the outer peripheral side of the face plate member 17 toward the outer surface side of the face plate member 17 with respect to the parallel axis y parallel to the center axis of the face plate member 17. The inclination angle α of the central axis x of the shower hole 18 with respect to the parallel axis y of the face plate member 17 is preferably set to 3 to 10 °. In the present embodiment, the inclination angle α of the shower hole 18 is set to 5 °.

  When the inclination angle α is less than 3 °, the range of hot water discharged from the shower hole 18 cannot be sufficiently expanded, and the water discharge tends to be strongly applied to the skin, and the feeling of use of the shower is shown. Is not preferable because of worsening. On the other hand, when the inclination angle α exceeds 10 °, the sprinkling range of hot water discharged from the shower hole 18 is excessively widened, which makes it difficult to obtain a desired shower effect.

  As shown in FIG. 8, a shallow tapered recess 181 is formed on the surface of the face plate member 17 around the outer end of the shower hole 18. A regulating surface 25 is formed on the inner surface on the outer peripheral side of the face plate member 17 in the recess 181. The restriction surface 25 restricts the sprinkling range of the hot water discharged from the shower hole 18 from being excessively widened.

  Further, the water spray end surface 26 connected to the outer end portion of the shower hole 18 and the regulating surface 25 is a slope that is located on the inner side of the outer end surface 27 of the face plate member 17 toward the outer peripheral side. The oblique angle β of the water spray end face 26 with respect to the outer end face 27 of the face plate member 17 is preferably set to 3 to 10 °. When the oblique angle β is smaller than 3 °, it is not preferable because it is difficult to widen the water spray range discharged from the shower hole 18. On the other hand, when the oblique angle β is larger than 10 °, it is not preferable because the sprinkling range of the hot water discharged from the shower hole 18 tends to be excessively widened.

  As shown in FIGS. 2 and 3, a large number of water discharge holes 28 are opened at regular intervals in the circumferential direction so as to surround the shower holes 18 on the outer peripheral portion of the face plate member 17 from the shower holes 18. The water discharge hole 28 communicates with the communication passage 15 and is configured to discharge hot water. The hot water sprayed from the shower hole 18 is kept warm. The axis of the water discharge hole 28 is set substantially parallel to the central axis x of the shower hole 18.

Next, the effect | action of the watering structure in the shower head 10 of this embodiment comprised as mentioned above is demonstrated.
As shown in FIG. 3, when hot water is discharged as a shower from the shower hole 18 of the face plate member 17 of the shower head 10, hot water is supplied to the ring member 16 from the flow path 13 and the communication path 15 of the main body 11. It guides to the hot water introduction part 19 of the face plate member 17 through the hole 21. At this time, as shown by the arrows in FIG. 5, the hot water is guided by the pair of guide walls 176 and flows into the shower hole 18 while being swirled from the hot water introducing portion 19. For this reason, as shown by the two-dot chain line in FIG. 3 and FIG.

  In this case, as shown in FIG. 8, the inclination angle α of the central axis x of the shower hole 18 with respect to the parallel axis y parallel to the central axis of the face plate member 17 is set to 5 °. For this reason, the center of the hot water from the shower hole 18 goes to the outer peripheral side from the extended line of the parallel axis y. Therefore, in the case of this embodiment, compared with the case where the central axis x of the shower hole 18 is the same as the parallel axis y, the contact with hot water against the skin is softened and the watering range of the entire shower can be expanded. .

  Further, since the annular restriction surface 25 is formed around the outer end portion of the shower hole 18, the hot water on the outer peripheral side of the hot water discharged from the shower hole 18 hits the restriction surface 25 and the hot water is not spread too much. It is regulated and the range of water spray is adjusted.

  In addition, as shown in FIG. 2, a large number of water discharge holes 28 are provided on the outer periphery of the face plate member 17 from the shower holes 18 so as to surround the shower holes 18, and hot water is discharged from each of the water discharge holes 28.
