Further, the flow channel case 5 is connected to the tip of the branch portion 7 . The channel case 5 has a cylindrical shape with a curved tip, and a channel pipe 8 is arranged inside to constitute a body channel 9 (see FIG. 2) of the faucet body 2 .

流路ケース5の先端には吐出部3が配置されている。吐出部3は流路配管8の先端に接続されて、水栓本体2にて混合割合及び流量が調整されて本体流路9を通ってきた水を水栓1の外部へ吐出するものである。吐出部3は、固定弁11、可動弁12、支持筒13、操作部としての操作環14、散水部としての散水板15、及び吐出口部16を含んで構成される。また、吐出部3は吐出される水の吐出形態をストレート状の直流水とシャワー状の散水に切替可能な切替部10を有する。切替部10は水の吐出部3において流路を切り替えることにより吐出形態を切り替えるものであり、吐出部3のうち固定弁11、可動弁12、操作環14を含んで構成される。 A discharge part 3 is arranged at the tip of the flow path case 5 . The discharge part 3 is connected to the tip of the flow path pipe 8, and discharges the water, which has been adjusted in mixing ratio and flow rate in the faucet main body 2, and has passed through the main flow path 9, to the outside of the faucet 1. . The discharge portion 3 includes a fixed valve 11 , a movable valve 12 , a support tube 13 , an operation ring 14 as an operation portion, a water spray plate 15 as a water spray portion, and a discharge port portion 16 . In addition, the discharge part 3 has a switching part 10 that can switch the discharge form of discharged water between straight DC water and shower-like water spray. The switching portion 10 switches the discharge mode by switching the flow path in the water discharge portion 3 , and includes a fixed valve 11 , a movable valve 12 and an operation ring 14 in the discharge portion 3 .

図2の断面図に基づいて吐出部3を構成する部材の位置関係を簡単に説明する。流路配管8の先端に固定弁11が接続されており、この固定弁11に可動弁12、吐出口部16が直列に位置している。また、支持筒13は固定弁11及び可動弁12を内側に収納している。操作環14は支持筒13及び吐出口部16を部分的に覆っており、操作環14の先端内側に散水板15が位置する。 The positional relationship of the members forming the ejection portion 3 will be briefly described based on the cross-sectional view of FIG. 2 . A fixed valve 11 is connected to the tip of the flow path pipe 8 , and a movable valve 12 and a discharge port 16 are positioned in series with the fixed valve 11 . Further, the support cylinder 13 accommodates the fixed valve 11 and the movable valve 12 inside. The operation ring 14 partially covers the support tube 13 and the discharge port 16 , and the sprinkler plate 15 is positioned inside the tip of the operation ring 14 .

図2に示すように、固定弁11は全体として側面視凸状をなす部材であり、樹脂にて形成されている。固定弁11の基端側は挿入部111となっており、流路配管8に内嵌されている。挿入部111の先端側にはフランジ部112が形成されており、フランジ部112の外周縁において180度離間した位置には一対の係止溝113が形成されている(図3参照)。また、フランジ部112よりも先端側はフランジ部112より小径で略円筒状をなす固定弁体114となっており、外周にはOリング114aが装着されている。 As shown in FIG. 2, the fixed valve 11 is a member having a convex shape as a whole when viewed from the side, and is made of resin. The base end side of the fixed valve 11 is an insertion portion 111 that is fitted inside the flow path pipe 8 . A flange portion 112 is formed on the distal end side of the insertion portion 111, and a pair of locking grooves 113 are formed at positions spaced apart by 180 degrees on the outer peripheral edge of the flange portion 112 (see FIG. 3). A fixed valve body 114 having a diameter smaller than that of the flange portion 112 and having a substantially cylindrical shape is formed on the distal end side of the flange portion 112, and an O-ring 114a is attached to the outer periphery thereof.

図3に固定弁11を固定弁体114側(先端側)から見た斜視図を示す。固定弁体114の端面115にはその中心から点対称に形成された一対の扇状をなす固定弁孔116が形成されており、この一対の固定弁孔116には挿入部111から連通する流路が形成されている。固定弁孔116の開き角度、すなわち扇状部分の根元から見た開き角度は約90度である。また、端面115のうち一対の固定弁孔116の周方向間には一対の肉抜き穴117が形成されているが、この肉抜き穴117は有底であり流路を構成しない。このため、固定弁11には、流路配管8から挿入部111内に流入した水が固定弁体114の内側を通り端面115に形成された一対の固定弁孔116から流出する流路が形成されている(図3の実線矢印)。 FIG. 3 shows a perspective view of the fixed valve 11 as seen from the fixed valve body 114 side (front end side).

The opening angle of the fixed valve hole 116, that is, the opening angle seen from the base of the fan-shaped portion is about 90 degrees. A pair of lightening holes 117 are formed in the end face 115 between the pair of fixed valve holes 116 in the circumferential direction. Therefore, in the fixed valve 11, a flow path is formed through which water flowing into the insertion portion 111 from the flow path pipe 8 passes through the inside of the fixed valve body 114 and flows out from the pair of fixed valve holes 116 formed in the end face 115. (solid line arrow in FIG. 3).

固定弁11の端面115には外周縁に一対の規制壁部118が形成されている。規制壁部118は断面略矩形状をなし、平面視で端面115の外周縁に沿う円弧状に形成されている。一対の規制壁部118は端面115の外周縁のうち一対の固定弁孔116の径方向外側に位置しているが、規制壁部118の角度範囲は固定弁孔116の開き角度よりも少し狭い。 A pair of regulating wall portions 118 are formed on the outer peripheral edge of the end face 115 of the fixed valve 11 . The restricting wall portion 118 has a substantially rectangular cross section and is formed in an arc shape along the outer peripheral edge of the end face 115 in plan view. The pair of regulating wall portions 118 are positioned radially outside the pair of fixed valve holes 116 on the outer periphery of the end face 115, but the angle range of the regulating wall portions 118 is slightly narrower than the opening angle of the fixed valve hole 116. .

FIG. 4 shows a perspective view of the movable valve 12 viewed from the base end side. The movable valve 12 is a member having a movable valve body 121 on the proximal end side and a cylindrical portion 122 on the distal end side, and is made of resin. The movable valve body 121 has a flange-shaped base 123 and a valve seat 124 protruding from the base 123 toward the base end side. The valve seats 124 are formed point-symmetrically with respect to the center of the pedestal 123 in a plan view, and form a pair of fan shapes with the central portions integrated. A pair of fan-shaped movable valve holes 125 are formed through the valve seat 124 , and the pair of movable valve holes 125 have substantially the same shape as the pair of fixed valve holes 116 . An eight-shaped elastic ring 126 is attached to the valve seat 124 so as to surround the pair of movable valve holes 125 , and the surface of the elastic ring 126 protrudes from the movable valve holes 125 toward the base end side.

図4に示すように、弁座124は外周縁が円弧状に形成されており、その直径は固定弁11に形成された一対の規制壁部118の内周面間の距離より短い。また、弁座124の外周縁の周方向の一端部には、180度離間した位置に一対の係止片124aが径方向外側に向けて形成されており、この一対の係止片124aの両外端間の距離は一対の規制壁部118の内周面間の距離より長い。台座123上において弁座124が形成されていない部分は一対の凹部127となっており、この凹部127は散水流路を構成する(図4の破線矢印)。円筒部122は台座123よりも小径であり、その内側は空洞となって一対の可動弁孔125に連通する直流水流路を構成し(図4の実線矢印)、外側は凹部127から続く散水流路を構成する(図4の破線矢印)。円筒部122の先端側外周面には軸線方向に延びる凹溝122aが周方向に90度間隔で4箇所形成されており、円筒部122の先端側内周面には雌ネジ122bが形成されている。 As shown in FIG. 4 , the valve seat 124 has an arcuate outer peripheral edge, the diameter of which is shorter than the distance between the inner peripheral surfaces of the pair of regulation walls 118 formed on the fixed valve 11 . A pair of locking pieces 124a are formed at one end in the circumferential direction of the outer peripheral edge of the valve seat 124 at positions spaced apart by 180 degrees so as to face radially outward. The distance between the outer ends is longer than the distance between the inner peripheral surfaces of the pair of restricting walls 118 . A pair of recessed portions 127 are formed on the base 123 where the valve seat 124 is not formed, and the recessed portions 127 form a water sprinkling channel (broken line arrows in FIG. 4). The cylindrical portion 122 has a diameter smaller than that of the pedestal 123. The inner side of the cylindrical portion 122 is hollow and constitutes a DC water flow path communicating with the pair of movable valve holes 125 (solid line arrows in FIG. 4). (dashed arrow in FIG. 4). Four grooves 122a extending in the axial direction are formed on the outer peripheral surface of the cylindrical portion 122 at intervals of 90 degrees in the circumferential direction. there is

FIG. 5 shows a perspective view of the support tube 13 viewed from the base end side. The support tube 13 is a cylindrical member made of resin. A male thread 131 is formed on the outer peripheral surface of the base end side of the support cylinder 13 and is screwed into the female thread 5 a formed in the flow path case 5 . A V-ring 132 is attached to the outer peripheral surface of the support tube 13 on the distal end side.

また、支持筒13の先端側内周面には、同一形状をなす多数の支持枠133が周方向に一定間隔で形成されている。支持枠133はいずれも軸線方向に長い形状であり、支持筒13の内周面から径方向内側に向けて立ち上がっている。支持枠133のうち、基端側は内接する円の直径が相対的に大きい(立ち上がりの高さが低い)大径枠133aとなっている。また、その先端側は段差133bを介して内接する円の直径が相対的に小さい(立ち上がりの高さが高い)小径枠133cとなっている。大径枠133aに内接する円の直径は可動弁12の台座123の直径よりも長く、小径枠133cに内接する円の直径は可動弁12の台座123の直径より短くかつ可動弁12の円筒部122の直径よりも長くなっている。支持筒13のうち支持枠133に囲まれた内周面は可動弁12の円筒部122の外側とともに散水流路を構成する。なお、支持筒13の内周面は大径枠133aの形成部分に比して小径枠133cの形成部分が肉厚となり小径である。 A large number of support frames 133 having the same shape are formed at regular intervals in the circumferential direction on the inner peripheral surface of the support tube 13 on the distal end side. Each of the support frames 133 has a long shape in the axial direction, and rises radially inward from the inner peripheral surface of the support cylinder 13 . The base end side of the support frame 133 is a large-diameter frame 133a in which the diameter of the inscribed circle is relatively large (the rising height is low). Further, on the tip side thereof, a small-diameter frame 133c having a relatively small diameter (high rising height) of a circle inscribed through the step 133b is formed. The diameter of the circle inscribed in the large-diameter frame 133a is longer than the diameter of the seat 123 of the movable valve 12, and the diameter of the circle inscribed in the small-diameter frame 133c is shorter than the diameter of the seat 123 of the movable valve 12, and the cylindrical portion of the movable valve 12. It is longer than the 122 diameter. The inner peripheral surface of the support cylinder 13 surrounded by the support frame 133 constitutes a water sprinkling channel together with the outside of the cylindrical portion 122 of the movable valve 12 . The inner peripheral surface of the support cylinder 13 has a smaller diameter than the portion where the large-diameter frame 133a is formed because the portion where the small-diameter frame 133c is formed is thicker.

As shown in FIG. 2, a rectifying plate 163 for regulating the water flow when direct current water is discharged and a filter 164 for filtering foreign substances are arranged inside the discharge port 16, but the description of these is omitted.

吐出部3の組付け構成について
図2に示すように、吐出部3は一部が流路ケース5内に位置する形で組み付けられている。具体的には、流路ケース5内の流路配管8に固定弁11の挿入部111が内嵌されている。流路配管8には図示しない係止部が2箇所に形成されており、固定弁11の挿入部111を流路配管8に挿入した際に係止部に固定弁11の係止溝113が係止され、固定弁11が流路配管8に対して相対回転不能に位置決めされる。また、固定弁11に形成された一対の規制壁部118の径方向内側には可動弁12の弁座124が位置しており、弁座124に形成された一対の係止片124aは周方向において一対の規制壁部118間に位置する。
Assembly Structure of Discharge Portion 3 As shown in FIG. Specifically, the insertion portion 111 of the fixed valve 11 is fitted into the channel pipe 8 in the channel case 5 . Two locking portions (not shown) are formed in the flow pipe 8, and when the insertion portion 111 of the fixed valve 11 is inserted into the flow pipe 8, the locking groove 113 of the fixed valve 11 is formed in the locking portion. It is locked and the fixed valve 11 is positioned so as not to rotate relative to the flow path pipe 8 . Further, the valve seat 124 of the movable valve 12 is positioned radially inside the pair of restricting wall portions 118 formed on the fixed valve 11, and the pair of locking pieces 124a formed on the valve seat 124 extend circumferentially. is positioned between the pair of restricting wall portions 118 at .

支持筒13は、固定弁11及び可動弁12を内側に配置した状態で雄ネジ131が流路ケース5の雌ネジ5aに螺合されて流路ケース5に対して相対回転不能となっている。支持筒13の内周面には固定弁11のOリング114aが圧接しており、固定弁11のフランジ部112が支持筒13の基端縁に着座して両者が軸線方向に位置決めされている。可動弁12はフランジ状の台座123が支持筒13に形成された支持枠133の段差133bに着座して支持筒13に対して遊嵌状態で軸方向に位置決めされている。固定弁11の端面115と可動弁12の弁座124とは弾性リング126を介して対向している。 The male screw 131 of the support cylinder 13 is screwed into the female screw 5a of the flow channel case 5 in a state in which the fixed valve 11 and the movable valve 12 are arranged inside, so that the support cylinder 13 cannot rotate relative to the flow channel case 5. . The O-ring 114a of the fixed valve 11 is in pressure contact with the inner peripheral surface of the support cylinder 13, and the flange portion 112 of the fixed valve 11 is seated on the base end edge of the support cylinder 13 to position them in the axial direction. . The movable valve 12 is axially positioned in a loosely fitted state with the flange-like pedestal 123 seated on a step 133b of a support frame 133 formed on the support cylinder 13 . The end face 115 of the fixed valve 11 and the valve seat 124 of the movable valve 12 face each other with an elastic ring 126 interposed therebetween.

支持筒13の先端側には操作環14が外嵌されており、支持筒13に装着されたVリング132により両者間は水密状態となっている。さらに、吐出口部16が操作環14と一体形成された散水板15の挿通孔152を通って可動弁12に螺合されている。吐出口部16の大径部162は散水板15の係止段部153に係止し、さらに散水板15の凸部154が可動弁12の凹溝122aに係止している。このため、操作環14を回動させると、これに一体成形された散水板15も回動し、併せて可動弁12及び吐出口部16も回動することとなる。このとき、流路配管8に係止されている固定弁11及び流路ケース5に螺合されている支持筒13は回動しない。 An operation ring 14 is fitted on the front end side of the support cylinder 13, and a V-ring 132 attached to the support cylinder 13 makes a watertight state between them. Further, the discharge port portion 16 is screwed to the movable valve 12 through the insertion hole 152 of the sprinkler plate 15 integrally formed with the operating ring 14 . The large-diameter portion 162 of the discharge port 16 is engaged with the engagement stepped portion 153 of the sprinkler plate 15 , and the convex portion 154 of the sprinkler plate 15 is engaged with the concave groove 122 a of the movable valve 12 . Therefore, when the operation ring 14 is rotated, the sprinkler plate 15 integrally formed therewith is also rotated, and the movable valve 12 and the discharge port portion 16 are also rotated together. At this time, the fixed valve 11 locked to the channel pipe 8 and the support cylinder 13 screwed to the channel case 5 do not rotate.

また、可動弁12は、これに形成された係止片124aが固定弁11に形成された一対の規制壁部118の間でのみ回動可能であるため、操作環14の回動も同じ範囲に規制され、操作環14は約90度の範囲で往復回動可能となる。 In addition, since the locking piece 124a formed on the movable valve 12 is rotatable only between the pair of regulating wall portions 118 formed on the fixed valve 11, the operation ring 14 is also rotatable within the same range. , and the operation ring 14 can reciprocate within a range of about 90 degrees.

吐出部3からの吐出形態の切替操作について
吐出部3は、固定弁11の端面115に対して可動弁12の弁座124が弾性リング126を介して対向している。操作環14を回動させると可動弁12は固定弁11に対して約90度の範囲内で回動する。可動弁12の弁座124は約90度の開き角度を有する扇状をしている。操作環14を回動させると、可動弁12の可動弁孔125が固定弁11の固定弁孔116と対向して連通する位置(連通位置)と、対向せず連通しない位置(非連通位置)との間で回動する。
Switching Operation of Discharge Mode from Discharge Portion 3 In the discharge portion 3 , the valve seat 124 of the movable valve 12 faces the end surface 115 of the fixed valve 11 via an elastic ring 126 . When the operation ring 14 is rotated, the movable valve 12 rotates within a range of approximately 90 degrees with respect to the fixed valve 11 . The valve seat 124 of the movable valve 12 has a fan shape with an opening angle of about 90 degrees. When the operation ring 14 is rotated, a position where the movable valve hole 125 of the movable valve 12 faces and communicates with the fixed valve hole 116 of the fixed valve 11 (communication position) and a position where the movable valve hole 125 does not face and does not communicate with the fixed valve hole 116 (non-communication position). rotate between

可動弁12が連通位置にある場合には、固定弁孔116は可動弁12の可動弁孔125に対向して連通し、可動弁孔125の周囲には弾性リング126が配置されている。このため、切替部10は、固定弁孔116(図3の実線矢印)から可動弁孔125を通り円筒部122の内側を経て(図4の実線矢印)、吐出口部16に連通する直流水流路を形成し、水は吐出口部16の先端から直流水として吐出される。 When the movable valve 12 is in the communication position, the fixed valve hole 116 communicates with the movable valve hole 125 of the movable valve 12 so as to face it, and the elastic ring 126 is arranged around the movable valve hole 125 . For this reason, the switching unit 10 allows a DC water flow to communicate with the discharge port 16 from the fixed valve hole 116 (solid line arrow in FIG. 3), through the movable valve hole 125, and through the inner side of the cylindrical portion 122 (solid line arrow in FIG. 4). A passage is formed, and water is discharged from the tip of the discharge port 16 as DC water.

一方、操作環14を手指で把持して約90度回動させると、操作環14の回転に伴って可動弁12も約90度回動し、可動弁孔125が固定弁11の固定弁孔116と連通しない位置(非連通位置)となる。この位置では、固定弁孔116は可動弁孔125ではなく弁座124が形成されていない凹部127と連通する。そして、凹部127は台座123と支持筒13の大径枠133aとの間、さらに円筒部122の外側と支持筒13との間(図4の破線矢印)を経て、散水板15に連通している。このため、切替部10は、固定弁孔116(図3の実線矢印)から可動弁12の凹部127を通り円筒部122の外側と支持筒13の内側との間(図4の破線矢印)を経て散水板15に至る散水流路を形成し、水は散水孔151から散水として吐出される。これを直流水にするには、再び操作環14を手指で把持し今度は反対方向に約90度回動させれば、可動弁12の可動弁孔125が再び固定弁11の固定弁孔116と対向する連通位置に切り替えられて先に説明した直流流路が形成される。 On the other hand, when the operation ring 14 is gripped by fingers and rotated by about 90 degrees, the movable valve 12 is also rotated by about 90 degrees with the rotation of the operation ring 14, and the movable valve hole 125 becomes the fixed valve hole of the fixed valve 11. 116 (non-communication position). At this position, the fixed valve hole 116 communicates not with the movable valve hole 125 but with the recess 127 in which the valve seat 124 is not formed. The recessed portion 127 communicates with the sprinkler plate 15 via between the pedestal 123 and the large-diameter frame 133a of the support tube 13 and between the outside of the cylindrical portion 122 and the support tube 13 (broken line arrow in FIG. 4). there is Therefore, the switching portion 10 extends from the fixed valve hole 116 (solid line arrow in FIG. 3) through the concave portion 127 of the movable valve 12 and between the outside of the cylindrical portion 122 and the inside of the support tube 13 (broken line arrow in FIG. 4). A water spray passage is formed to reach the water spray plate 15 , and water is discharged from the water spray holes 151 as water spray. In order to turn this into direct current water, the operating ring 14 is gripped again with fingers and rotated approximately 90 degrees in the opposite direction, so that the movable valve hole 125 of the movable valve 12 is again moved to the fixed valve hole 116 of the fixed valve 11. is switched to the communication position facing the , and the DC flow path described above is formed.

ここで、操作環14は散水板15を囲む壁部142を有しており、この壁部142の先端は散水板15より先端側に位置している。操作環14を手指で把持して操作する場合には操作環14の先端側を把持することがある。この場合、壁部142により操作環14(壁部142)の先端と散水板15の散水孔151との間の距離は、壁部142がない場合に比して長くなる。このため、手指が操作環14の壁部142に位置したとしても、手指と散水孔151との間の距離を長く確保することができ、手指が散水に触れにくくなる。 Here, the operation ring 14 has a wall portion 142 surrounding the sprinkler plate 15 , and the tip of the wall portion 142 is located on the tip side of the sprinkler plate 15 . When the operation ring 14 is gripped and operated with fingers, the distal end side of the operation ring 14 may be gripped. In this case, the wall portion 142 makes the distance between the tip of the operation ring 14 (the wall portion 142) and the water spray hole 151 of the water spray plate 15 longer than when the wall portion 142 is not provided. Therefore, even if a finger is positioned on the wall portion 142 of the operation ring 14, a long distance can be secured between the finger and the water spray hole 151, making it difficult for the finger to come in contact with water spray.
