  However, in order to change the water discharge direction of each water spray hole into a desired shower water discharge form, when forming the water spray hole in the same form as the cylindrical water spray hole formed in the water spray member of Patent Document 1, Although it is conceivable to open the watering holes one by one using a drill at a predetermined inclination angle and a predetermined inclination direction with respect to the surface of the watering member, it takes time. In addition, it is difficult to form a plurality of cylindrical water sprinkling holes using a mold with different inclination angles and inclination directions with respect to the surface of the water sprinkling member. That is, when the plurality of cylindrical water spray holes have different inclination angles and inclination directions with respect to the surface of the water spray member, it is difficult to release the water spray member from the mold. Furthermore, as shown in FIG. 11, there is known a watering hole 115 having a fan-like shape extending from the outlet 119 toward the back surface of the watering member 110. The water sprinkling holes 115 in this form can be in the water sprinkling direction inclined with respect to the surface of the water sprinkling member 110. Even if a plurality of water sprinkling holes 115 having different water discharge directions are formed in the water sprinkling member 110, the water sprinkling members are removed from the mold. Can be released. However, in the cross-sectional shape obtained by symmetrically cutting the water spray hole 115, the opening surface of the jet outlet 119 is inclined with respect to the bisector β of the angle α that extends by extending the opposing surfaces 115A and 115B. The water discharge direction D does not become stable along the bisector β of the angle α that extends by extending the opposing surfaces 115A and 115B, and the water discharge direction D is not stable. For this reason, it is difficult to form the sprinkling hole 115 of this form in the sprinkling member 110 to obtain a desired shower water discharge form.

  This invention is made | formed in view of the said conventional condition, Comprising: It is set as the problem which should be solved to provide the watering member which can be made into the desired shower water discharge form.

  In the water spray member, in the cross-sectional shape obtained by symmetrically cutting the water spray holes, the jet ports are opened so as to be orthogonal to the bisectors of the intersecting corners by extending each of the opposed surfaces of the first hole portion. For this reason, this water sprinkling member is a bisector of the corner where the direction of water discharge from each jet outlet extends in the cross-sectional shape obtained by symmetrically cutting each water spray hole and extends each of the opposing surfaces of the first hole portion. It becomes the direction along. Moreover, this water spray member can be made into the desired water discharge direction by changing the inclination angle of the opposing surface of a 1st hole part in the cross-sectional shape which cut | disconnected the water spray hole symmetrically.

  Therefore, the water spray member of the present invention can be in the desired shower water discharge form.

  Further, since the water spray member can be formed by expanding the water spray hole from the jet outlet toward the inflow port, the water spray member can be released from the mold even if a plurality of water spray holes having different water discharge directions are formed. it can. For this reason, the water sprinkling member can be manufactured by injection molding or the like.

The faucet body 5 has a trunk portion 5A and a water discharge pipe base portion 5B. The trunk portion 5A has a substantially cylindrical shape extending in the vertical direction with the faucet 1 attached to a top plate or the like. The trunk portion 5A has a hollow shape and houses a valve cartridge (not shown) therein. The valve cartridge is a hot and cold water mixing valve with a flow rate adjusting function and a water stop function. The valve cartridge has two inflow ports and one outflow port. In the valve cartridge, a downstream end of a water supply hose (not shown) is connected to one inflow port, and a downstream end of a hot water supply hose (not shown) is connected to the other inflow port. Moreover, the valve cartridge has connected the upstream end of the water discharge pipe which is not shown in figure to the outflow port. The water discharge pipe has a shower hose 8 (described later) connected to the downstream end.

  The water discharge pipe base 5B is connected to the side surface of the trunk portion 5A, and extends obliquely upward from the side surface of the trunk portion 5A with the faucet fitting 1 attached to a top plate or the like. The water discharge pipe base 5B has a hollow shape communicating with the body 5A. The water discharge pipe base 5B is attached by inserting a support member 6 at the tip. The support member 6 forms an insertion hole in the axial direction. Moreover, the support member 6 is substantially cylindrical shape, and the front-end | tip part 6A protrudes from the front-end | tip of the water discharge pipe base 5B. The outer peripheral shape of the water discharge pipe base 5B is the same as the outer peripheral shape of the hand shower part 7, and when the hand shower part 7 is attached to the tip, the water discharge pipe base part 5B and the hand shower part 7 become an outer shape.

  The hand shower portion 7 has a concave portion 7A into which the distal end portion 6A of the support member 6 can be inserted at the base portion. The hand shower portion 7 is detachably attached to the distal end of the water discharge tube base 5B by inserting the distal end portion 6A of the support member 6 attached to the water discharge tube base 5B into the recess 7A formed in the base. The hand shower section 7 forms a water passage 7B inside. The hand shower portion 7 has a mounting hole 7C formed at the downstream end of the water passage 7B. The mounting hole 7 </ b> C opens on the lower surface of the hand shower portion 7. The water discharging member 3 is attached to the hand shower portion 7 by inserting and fixing an upper portion of a joint member 70 described later into the mounting hole 7C.

  The shower hose 8 connects the downstream end to the upstream end of the water passage 7 </ b> B of the hand shower unit 7. The shower hose 8 is inserted through the insertion hole of the support member 6 attached to the water discharge pipe base 5B, and can be pulled out to a predetermined length from the tip of the support member 6 (water discharge pipe base 5B).

  The water discharge member 3 includes a water sprinkling member 10, a tubular member 30, an outer tubular member 50, a joint member 70, and a seal member 90. The water sprinkling member 10 has the water sprinkling part 11 and the side wall part 13, as shown in FIGS. The water sprinkling part 11 is disk shape. The side wall portion 13 has a cylindrical shape that rises upward from the outer peripheral edge of the water sprinkling portion 11. The watering part 11 has a plurality of watering holes 15A, 15B penetrating in the thickness direction. Each of the water spray holes 15 </ b> A and 15 </ b> B communicates with the inflow port 17 formed on the back surface 11 </ b> B of the water spray part 11 at the upstream end. Each of the water spray holes 15 </ b> A and 15 </ b> B communicates with a spout 19 formed on the surface 11 </ b> A of the water sprinkler 11 at the downstream end.

  The plurality of water spray holes 15 </ b> A and 15 </ b> B penetrating the water sprinkling portion 11 are inclined outward with respect to the direction in which the water discharge direction D is orthogonal to the surface 11 </ b> A of the water sprinkling portion 11. Further, the inclination angle in the water discharge direction D differs depending on the positions where the water spray holes 15A and 15B are formed. As shown in FIGS. 4 and 5, the water spray hole 15 </ b> B inclined at a small angle (less than 6 °) toward the outer direction with respect to the direction in which the water discharge direction D is orthogonal to the surface 11 </ b> A of the water spray part 11. Is formed in an inverted truncated cone shape having an opening area slightly larger than that of the jet nozzle 19.

  Further, as shown in FIG. 6, the water spray hole 15 </ b> A inclined at a large angle (6 ° or more) toward the outer direction with respect to the direction in which the water discharge direction D is orthogonal to the surface 11 </ b> A of the water spray part 11 is the first hole part. 12 and a second hole portion 14. The first hole 12 has a cross-sectional shape obtained by symmetrically cutting the water spray hole 15 </ b> A, and spreads in a fan shape from the jet outlet 19 toward the back surface 11 </ b> B of the water spray part 11. One facing surface 12A of the first hole 12 in a cross-sectional shape obtained by symmetrically cutting the watering hole 15A extends linearly in a direction that intersects the surface 11A of the watering part 11 substantially at a right angle. Further, the other facing surface 12B of the first hole portion 12 in a cross-sectional shape obtained by symmetrically cutting each water sprinkling hole 15A extends linearly in a direction inclined with respect to the surface 11A of the water sprinkling portion 11.

  In the cross-sectional shape obtained by symmetrically cutting the water spray hole 15A, the first hole portion 12 is opposed to the opposing surfaces 12A and 12B at symmetrical positions of the bisector β of the angle α that extends by extending the opposing surfaces 12A and 12B. The respective tip ends 19A and 19B are positioned to form a substantially circular outlet 19. In other words, the first hole portion 12 has a spout 19 formed so as to be orthogonal to the bisector β of the angle α intersecting each other by extending each of the opposing surfaces in a cross-sectional shape obtained by symmetrically cutting the water spray hole 15A. ing. Moreover, the jet nozzle 19 is formed in the convex part 16 which protruded from the surface 11A of the water sprinkling part 11. Specifically, the spout 19 has a cross-sectional shape obtained by symmetrically cutting the sprinkling hole 15A, and is orthogonal to the bisector β of the angle α extending and intersecting each of the facing surfaces 12A and 12B. The flat surface 18 is inclined with respect to 11A. The flat surface 18 has a substantially 3/4 circular shape cut by a straight line in contact with the outer periphery of the ejection port 19.

  The second hole portion 14 communicates with the inflow port 17 at the upstream end and communicates with the upstream end of the first hole portion 12 at the downstream end. The second hole 14 has a cross-sectional shape obtained by symmetrically cutting the water spray hole 15 </ b> A, and one opposing surface 14 </ b> A extends linearly continuously from the one opposing surface 12 </ b> A of the first hole 12. For this reason, one opposing surface 14 </ b> A of the second hole portion 14 extends in a direction that intersects with the back surface 11 </ b> B of the sprinkling portion 11 at a substantially right angle. The second hole portion 14 has a cross-sectional shape obtained by symmetrically cutting the water spray hole 15A, and the other facing surface 14B extends substantially parallel to the one facing surface 14A. For this reason, the other opposing surface 14 </ b> B of the second hole portion 14 also extends in a direction that intersects the back surface 11 </ b> B of the sprinkling portion 11 at a substantially right angle. Further, the second hole portion 14 has a cross-sectional shape obtained by symmetrically cutting the water spray hole 15 </ b> A, and the other facing surface 14 </ b> B is continuous with the other facing surface 12 </ b> B of the first hole portion 12. The boundary portion 14C where the other facing surface 12B of the first hole portion 12 and the other facing surface 14B of the second hole portion 14 are continuous is steeper than the inclination angle of the other facing surface 12B of the first hole portion 12. It is formed with various inclination angles. The inflow port 17 in which the upstream end of the second hole portion 14 communicates is a long hole that is long in the direction in which the other facing surface 12B of the first hole portion 12 extends in a plan view as viewed from above the flat portion. Both ends are formed in a semicircular shape having the same diameter as the diameter of the jet nozzle 19. The distance between the opposing surfaces 14A and 14B of the second hole 14 is at least twice the inner diameter of the jet port 19 (about 2.25 times). Thus, the water spray hole 15A having the first hole portion 12 and the second hole portion 14 is opposed to the first hole portion 12 in the cross-sectional shape in which the water discharge direction D from the jet outlet 19 is cut symmetrically with the water spray hole 15A. The surfaces 12A and 12B are extended along the bisector β of the angle α that intersects each other.

  As shown in FIG. 4, the water sprinkling part 11 is changing the water discharge direction D according to the position in which the water sprinkling hole 15A is formed. That is, each water spray hole 15 </ b> A changes the inclination angle of the other facing surface 12 </ b> B of the first hole portion 12 with respect to the surface 11 </ b> A of the water spray portion 11 in accordance with the water discharge direction D. When the water discharge direction D of each water spray hole 15A is changed to a predetermined direction in this way, when shower water discharge is performed to discharge water only from the spout 19, water is discharged from the surface 11A of the water spray portion 11 as shown in FIG. The water discharge area | region Z in the virtual surface parallel to the surface 11A of the water sprinkling part 11 in the position away in the direction D can be made into the water discharge form which becomes a rectangular shape.

  As shown in FIGS. 4 and 5, the cylindrical member 30 has a cylindrical shape having an inner diameter larger than the outer diameter of the watering member 10. The center of the water sprinkling part 11 of the water sprinkling member 10 is positioned on the central axis of the pipe member 30 by the connecting part 20 that connects the inner peripheral face of the pipe member 30 and the water sprinkling member 10 outer peripheral face. The spout 40 is connected with a gap so that a water discharge port 40 is formed between the outer peripheral portion of the water spray member 10 and the tip opening 30 </ b> A of the tubular member 30. In this manner, the water discharge member 3 is formed with the water discharge port 40 so as to go around the periphery of the water spray member 10.

  As shown in FIG. 1, the outer cylinder member 50 has an inner diameter slightly larger than the outer diameter of the cylinder member 30 and the maximum outer diameter of a joint member 70 described later. The outer cylinder member 50 has a knob 51 extending outward from one place on the outer peripheral surface. When the knob 51 is picked and the outer cylinder member 50 is rotated clockwise or counterclockwise around the central axis, the water spray member 10 and the cylinder member 30 connected by the connector 20 move up and down.

  The joint member 70 has a water passage hole 71 penetrating in the vertical direction. The joint member 70 has a circular outer shape in cross section perpendicular to the central axis extending in the vertical direction. The joint member 70 is housed in the outer cylinder member 50, and the upper part projects upward from the upper end opening of the outer cylinder member 50. The joint member 70 is fixed by inserting an upper portion protruding upward from the upper end opening of the outer cylinder member 50 into the mounting hole 7C of the hand shower portion 7 in a watertight manner. In this manner, the water discharge member 3 is attached to the water discharge portion 3A of the faucet fitting 1. The outer cylinder member 50 is rotatable around the central axis with respect to the joint member 70.

  The seal member 90 is attached around the lower portion of the joint member 70. When the water spraying member 10 and the tubular member 30 connected by the connecting portion 20 rise and the side wall 13 of the water spraying member 10 comes into contact with the lower surface, the seal member 90 is connected to the joint member 70 and the side wall 13 of the water spraying member 10. Seal the space in a watertight manner. Further, the seal member 90 seals between the joint member 70 and the tubular member 30 in a watertight manner.

  When the faucet fitting 1 having the water discharging member 3 having such a configuration attached to the water discharging portion is rotated in the clockwise direction around the central axis when the outer cylinder member 50 is viewed from the direction facing the surface 11A of the water sprinkling portion 11. The water sprinkling member 10 and the tubular member 30 connected by the connecting portion 20 rise, and the lower surface of the seal member 90 comes into contact with the upper surface of the side wall portion 13 of the water sprinkling member 10. In this state, when the valve handle is opened by operating the operation handle 9 of the faucet fitting 1, shower water discharge is performed in which water is discharged from only the plurality of outlets 19. That is, the water supplied to the water passage hole 71 formed in the joint member 70 of the water discharge member 3 through the outlet port of the valve cartridge, the water discharge pipe, the shower hose 8, and the water flow path 7B of the hand shower portion 7 is sealed. Since the lower surface of the seal body 81 of the member 90 is in contact with the upper surface of the side wall portion 13 of the water sprinkling member 10, it does not flow out between the side wall portion 13 of the water sprinkling member 10 of the water discharge member 3 and the tubular member 30. Water is passed through only a plurality of water sprinkling holes 15A and 15B formed in ten water sprinkling portions 11. When the water discharge member 3 performs shower water discharge, as shown in FIG. 7, the water discharge region Z in a virtual plane parallel to the surface 11 </ b> A of the water sprinkling part 11 is located at a position away from the surface 11 </ b> A of the water sprinkling part 11 in the water discharge direction D. It becomes rectangular.

  In addition, when the water discharger member 3 is rotated counterclockwise around the central axis when the outer cylinder member 50 is rotated in the counterclockwise direction when viewed from the direction facing the surface 11A of the watering part 11, the water discharging member 3 and the watering member 10 connected by the connecting part 20 The cylindrical member 30 is lowered, and the lower surface of the seal member 90 and the upper surface of the side wall portion 13 of the water spray member 10 are separated. In addition, the lower end portion of the cylindrical member 30 of the water discharge member 3 protrudes downward from the lower end opening of the outer cylindrical member 50. In this state, when the valve handle is opened by operating the operation handle 9 of the faucet fitting 1, rectified and discharged water discharged from the plurality of outlets 19 and the outlet 40 is executed. That is, the water supplied to the water passage hole 71 formed in the joint member 70 of the water discharging member 3 through the outlet port of the valve cartridge, the water discharge pipe, the shower hose 8, and the water passage 7 </ b> B of the hand shower unit 7 is discharged water. It flows out between the side wall part 13 of the water sprinkling member 10 of the member 3 and the cylindrical member 30 and is passed through the spout 40 and water is passed through the plurality of 15A and B15 formed in the water sprinkling part 11 of the water sprinkling member 10. Is done. When the water discharge member 3 executes rectified water discharge, the water discharge member 3 is in the form of water discharged straightly straightened.

  The water sprinkling member 10 according to the first embodiment has a plurality of water spray members 10 whose upstream end communicates with an inflow port 17 formed on the back surface 11B of the water sprinkling part 11 and whose downstream end communicates with a spout 19 formed on the surface 11A of the water sprinkling part 11. Watering holes 15A and 15B are formed. 15 A of sprinkling holes have the 1st hole part 12 extended in fan shape toward the back surface 11B of the sprinkling part 11 from the jet nozzle 19 in the cross-sectional shape cut | disconnected to object. Further, the sprinkling hole 15A extends from each of the opposing surfaces 12A and 12B of the first hole portion 12 at a symmetrical position of the bisector β of the angle α and intersects each tip 19A of the opposing surfaces 12A and 12B. , 19B are located to form a spout 19.

  The water sprinkling member 10 has a cross-sectional shape obtained by symmetrically cutting the water sprinkling holes 15A so that each of the facing surfaces 12A and 12B of the first hole 12 extends and intersects with a bisector β of an angle α intersecting each other. The spout 19 is open. For this reason, this water sprinkling member 10 has an angle at which the water discharge direction D from each spout 19 extends and intersects each of the opposed surfaces of the first hole 12 in a cross-sectional shape obtained by symmetrically cutting each water spout 15A. The direction is along the bisector β of α. Moreover, this water sprinkling member 10 can be made into the desired water discharge direction D by changing the inclination angle of the opposing surface of the 1st hole part 12 in the cross-sectional shape which cut | disconnected the water sprinkling hole 15A symmetrically.

  Therefore, the watering member 10 of the present invention can be in the desired shower water discharge form.

  Further, the spout 19 of the water sprinkling member 10 according to the first embodiment is formed on the convex portion 16 protruding from the surface 11 </ b> A of the water sprinkling portion 11. For this reason, the front-end | tip of a brush can be applied to the circumference | surroundings of the several jet nozzle 19 formed in the surface 11A of the water sprinkling part 11, and the surface 11A of the water sprinkling part 11 can be cleaned easily. Moreover, this water sprinkling member 10 makes the opposing surfaces 12A and 12B of the 1st hole part 12 extended in fan shape toward the back surface 11B of the water sprinkling part 11 in the cross-sectional shape which cut | disconnected the water sprinkling hole 15A symmetrically. Therefore, the water discharge direction D can be stabilized.

  Further, the watering hole 15 </ b> A of the watering member 10 of the first embodiment has a second hole portion 14. The second hole portion 14 communicates with the inflow port 17 at the upstream end and communicates with the upstream end of the first hole portion 12 at the downstream end. Still, the second hole portion 14 has a cross-sectional shape cut with the sprinkling hole 15A as a target, and the opposing surfaces 14A and 14B extend in parallel. For this reason, in the cross-sectional shape which cut | disconnected the water sprinkling hole 15A symmetrically, compared with the case where the water sprinkling hole 15A is formed only by the 1st hole part 12 extended in fan shape from the jet nozzle 19 to the inflow port 17, the back surface 11B of the water sprinkling part 11 It is possible to reduce the opening area of the inflow port 17 formed in the above. Therefore, this water sprinkling member 10 can ensure the strength without the thickness of the portion where the plurality of water sprinkling holes 15A are formed becoming too thin. Moreover, this water sprinkling member 10 has few restrictions of positioning of the several jet nozzle 19 formed in 11 A of surfaces of the water sprinkling part 11. FIG. That is, the positions of the plurality of jet outlets 19 are not easily restricted by the positions of the plurality of inlets 17 formed on the back surface 11 </ b> B of the water spray member 10.

  Further, in the watering member 10, the watering hole 15 </ b> A has a first hole portion 12 and a second hole portion 14. The first hole 12 has a cross-sectional shape obtained by symmetrically cutting the watering hole 15A, and one opposing surface 12A extends linearly in a direction intersecting substantially at right angles to the surface 11A of the watering part 11, and the other opposing surface The surface 12B extends in a direction inclined with respect to the surface 11A of the sprinkler 11. Further, the second hole portion 14 has a downstream end communicating with the upstream end of the first hole portion 12 and has a cross-sectional shape in which the water spray holes 15A are cut symmetrically, and one opposing surface 14A is one of the first hole portions 12. Continuously extending to the facing surface 12A, it extends in a straight line, and extends in a direction that intersects the back surface 11B of the sprinkling portion 11 substantially at a right angle. The second hole portion 14 has a cross-sectional shape obtained by symmetrically cutting the water spray hole 15A, and the other facing surface 14B extends substantially parallel to the one facing surface 14A, and intersects the back surface 11B of the water sprinkling portion 11 at a substantially right angle. Extending in the direction. For this reason, even if it forms the some water spray hole 15A from which the water discharge direction D differs, the water spray part 11 can be released from a shaping | molding die. For this reason, this watering member 10 can be easily manufactured by injection molding or the like.

(2) Although the water spout 15A of Example 1 was formed in the convex part 16 in which the jet nozzle 19 protruded from the surface 11A of the sprinkler part 11, as shown in FIG.9 and FIG.10, the jet nozzle 19 is formed. You may form in the recessed part 60 dented rather than the surface 11A of the water sprinkling part 11. FIG. As shown in FIG. 9, the recess 60 is formed in a circular outer peripheral edge, in which the jet port 19 is formed at a position approaching the outer peripheral edge, and toward the outer peripheral edge of the jet port 19. May be constituted by an inclined surface 61 inclined from a substantially circular outer peripheral edge surrounding the outer periphery. Further, as shown in FIG. 10, the concave portion has a substantially circular first inclined surface 63 in which a spout 19 is formed at the center and a part of the outer peripheral edge is notched linearly and is inclined, and the first A second inclined surface 65 that surrounds the inclined surface 63 and is inclined toward the first inclined surface 63 from a substantially circular outer peripheral edge connected to both ends of the cut-out linear portion of the first inclined surface 63. Also good. Thus, if the spout 19 is formed in the recessed part 60 dented from the surface 11A of the water sprinkling part 11, the dirt of the surface 11A of the water sprinkling part 11 can be made difficult to adhere (in FIG. 9 and FIG. The same components as those in FIG.
(3) Although the water sprinkling member 10 of Example 1 was attached to the water discharge part of the faucet metal fitting 1 and was assembled | attached to the water discharge member 3 which can be switched to shower water discharge and rectification water discharge, the water spray part 11 is only shower water discharge. You may assemble | attach to the water discharge part of the faucet metal fitting which can be performed.
(4) When the water sprinkling member 10 of Example 1 performs shower water discharge, the water discharge area | region Z in the virtual surface parallel to the surface of the water sprinkling part 11 in the position away from the surface of the water sprinkling part 11 in the water discharge direction D is rectangular shape. However, the water spray holes 15 </ b> A and 15 </ b> B may be formed in the water spray part 11 so that the water discharge area Z on the virtual plane has another shape (square, star shape, etc.).
