以下に、本発明に係る実施形態を図面に基づいて詳細に説明する。なお、この実施形態によって本発明が限定されるものではない。 Below, an embodiment of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to this embodiment.

（実施形態）
図１、図２を用いて水栓２の概略構成について説明する。図１、図２は、本実施形態に係る水栓２の斜視図である。水栓２は、例えば、キッチン、洗面所、お風呂等に設けられる水栓装置である。図１に示すように、水栓２は、スパウト本体部４と、吐水部６と、ホース７（図２参照）と、操作部８とを備える。 (Embodiment)
The schematic configuration of the faucet 2 will be described with reference to Figures 1 and 2. Figures 1 and 2 are perspective views of the faucet 2 according to this embodiment. The faucet 2 is a faucet device that is installed in, for example, a kitchen, a washroom, a bath, etc. As shown in Figure 1, the faucet 2 includes a spout main body 4, a water discharge unit 6, a hose 7 (see Figure 2), and an operation unit 8.

スパウト本体部４は、水栓２の本体部分である。スパウト本体部４は内部に流路を有し、給水管（図示略）に接続されている。スパウト本体部４は、図示しない台座に支持されており、台座から上方へ直線的に延びた後、逆Ｕ字状に湾曲して吐水部６に接続される。 The spout body 4 is the main body of the faucet 2. The spout body 4 has an internal flow path and is connected to a water supply pipe (not shown). The spout body 4 is supported on a base (not shown) and extends linearly upward from the base before curving in an inverted U-shape and connecting to the water outlet 6.

吐水部６は、スパウト本体部４から供給される水を吐水するための部材である。吐水部６はスパウト本体部４の先端に対して引出し可能に取り付けられている。図１では吐水部６が引き出されていない状態を示し、図２では吐水部６が引き出された状態を示す。 The water discharge part 6 is a member for discharging water supplied from the spout body part 4. The water discharge part 6 is attached to the tip of the spout body part 4 so that it can be pulled out. Figure 1 shows the water discharge part 6 in a state where it is not pulled out, and Figure 2 shows the water discharge part 6 in a state where it is pulled out.

図２に示すように、吐水部６にはホース７が接続されている。ホース７は吐水部６へ水を供給する部材であり、スパウト本体部４の内部に収容されている。 As shown in FIG. 2, a hose 7 is connected to the water discharge portion 6. The hose 7 is a member that supplies water to the water discharge portion 6 and is housed inside the spout main body portion 4.

操作部８は、吐水部６による吐水／止水を切り替えるための部材である。図１、図２に示す水栓２はシングルレバー式であり、操作部８は吐水／止水の切替機能に加えて流量調整機能を有する。シングルレバー式の水栓２に限らず、吐水部６の吐水／止水を切り替える機能を有するものであれば、他の方式の水栓であってもよい。また、図１、図２に示す水栓２の形態は一例であり、スパウト本体部４や操作部８の仕様等は適宜変更してもよい。 The operating unit 8 is a member for switching between water discharge and water stop by the water discharge unit 6. The faucet 2 shown in Figures 1 and 2 is a single-lever type, and the operating unit 8 has a flow rate adjustment function in addition to a function for switching between water discharge and water stop. The faucet 2 is not limited to a single-lever type, and may be of another type as long as it has a function for switching between water discharge and water stop by the water discharge unit 6. In addition, the form of the faucet 2 shown in Figures 1 and 2 is one example, and the specifications of the spout body 4 and the operating unit 8 may be changed as appropriate.

本実施形態の水栓２では吐水部６の構造に工夫を行っている。図１、図２では吐水部６を概略的に図示したが、吐水部６の詳細な構造について、図３以降を参照しながら説明する。 The faucet 2 of this embodiment has been designed with an improved structure for the water outlet 6. Figures 1 and 2 show a schematic view of the water outlet 6, but the detailed structure of the water outlet 6 will be described with reference to Figures 3 onwards.

図３は、吐水部６の先端側を示す縦断面図である。図３に示すように、吐水部６は、第１筒状部材１０と、第２筒状部材１２と、吐水部材１４とを備える。 Figure 3 is a vertical cross-sectional view showing the tip side of the water discharger 6. As shown in Figure 3, the water discharger 6 includes a first tubular member 10, a second tubular member 12, and a water discharger member 14.

第１筒状部材１０および第２筒状部材１２はそれぞれ軸方向Ａに延びる筒状の部材である。図３に示すように、第１筒状部材１０および第２筒状部材１２はそれぞれ少なくとも先端部が円筒状である。第１筒状部材１０は第１内部流路１６を内側に形成し、第２筒状部材１２は第２内部流路１８を内側に形成する。第１内部流路１６は第１筒状部材１０と第２筒状部材１２の間に形成される空間である。図３では、第１内部流路１６および第２内部流路１８における水の流れを矢印で示している。 The first tubular member 10 and the second tubular member 12 are each tubular members extending in the axial direction A. As shown in FIG. 3, at least the tip of each of the first tubular member 10 and the second tubular member 12 is cylindrical. The first tubular member 10 forms a first internal flow path 16 on the inside, and the second tubular member 12 forms a second internal flow path 18 on the inside. The first internal flow path 16 is a space formed between the first tubular 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 arrows.

第１筒状部材１０および第２筒状部材１２は一体的な部材でもよく、別々の部材であってもよい。 The first tubular member 10 and the second tubular member 12 may be an integral member or separate members.

吐水部材１４は、第１筒状部材１０と第２筒状部材１２の間に配置される吐水用の部材である。図３に示すように、吐水部材１４は第２筒状部材１２に挿入して取り付けられる。 The water discharge member 14 is a member for discharging water that is disposed between the first cylindrical member 10 and the second cylindrical member 12. As shown in FIG. 3, the water discharge member 14 is inserted into and attached to the second cylindrical member 12.

吐水部材１４の縦断面図を図４に示す。図４に示すように、吐水部材１４は、一端２２から他端２４に向かって軸方向Ａに延びる筒状の形状を有する。吐水部材１４は中心部に貫通流路２０を有し、貫通流路２０には前述した第２筒状部材１２が挿入される。図示を省略しているが、貫通流路２０を形成する吐水部材１４の内壁面と第２筒状部材１２の外壁面にはそれぞれネジ形状が形成されており、互いに螺合される。 A longitudinal cross-sectional view of the water discharge member 14 is shown in Figure 4. As shown in Figure 4, the water discharge member 14 has a cylindrical shape extending in the axial direction A from one end 22 to the other end 24. The water discharge member 14 has a through flow passage 20 in the center, into which the second cylindrical member 12 described above is inserted. Although not shown in the figure, a screw shape is formed on the inner wall surface of the water discharge member 14 and the outer wall surface of the second cylindrical member 12 that form the through flow passage 20, and they are screwed together.

吐水部材１４の他端２４は、貫通流路２０を形成する箇所が部分的に突出した形状を有する。 The other end 24 of the water discharge member 14 has a shape in which the portion that forms the through flow passage 20 protrudes partially.

吐水部材１４はさらに、傾斜面２５を有する。傾斜面２５は、吐水部材１４の外周面として、軸方向Ａを中心とする周方向Ｒに延在する面である。傾斜面２５は一端２２と他端２４を接続しており、一端２２から他端２４に向かって外側に広がるように傾斜している。本実施形態の傾斜面２５は周方向Ｒの全周に延びており、環状につながっている。 The water discharge member 14 further has an inclined surface 25. The inclined surface 25 is the outer peripheral surface of the water discharge member 14 and is a surface that extends in the circumferential direction R centered on the axial direction A. The inclined surface 25 connects one end 22 to the other end 24, and is inclined so as to widen outward from the one end 22 to the other end 24. In this embodiment, the inclined surface 25 extends all the way around in the circumferential direction R, forming a ring shape.

図３に示すように、吐水部材１４を第２筒状部材１２に取り付ける際には、吐水部材１４の一端２２を第１筒状部材１０の開口部２６から第１内部流路１６へ挿入する。第２筒状部材１２との螺合によって吐水部材１４が位置決めされた状態では、開口部２６を形成する第１筒状部材１０の内縁部２８と傾斜面２５とが対向しながら互いに隙間を空けている。 As shown in FIG. 3, when attaching the water-discharging member 14 to the second tubular member 12, one end 22 of the water-discharging member 14 is inserted into the first internal flow path 16 through the opening 26 of the first tubular member 10. When the water-discharging member 14 is positioned by screwing it into the second tubular member 12, the inner edge 28 of the first tubular member 10 that forms the opening 26 and the inclined surface 25 face each other with a gap between them.

第１内部流路１６を流れる水は、吐水部材１４の傾斜面２５に沿って内縁部２８と傾斜面２５の間の隙間を通過するように流れ、傾斜面２５の端部３０から離れるように吐水される。これにより、環状の吐水流Ｓ１を形成する。 The water flowing through the first internal flow path 16 flows along the inclined surface 25 of the water discharge member 14, passing through the gap between the inner edge 28 and the inclined surface 25, and is discharged away from the end 30 of the inclined surface 25. This forms a circular water discharge flow S1.

第２内部流路１８を流れる水は、第２内部流路１８を軸方向Ａに沿って直線状に流れる。これにより、ストレート状の吐水流Ｓ２を形成する。 The water flowing through the second internal flow passage 18 flows linearly through the second internal flow passage 18 along the axial direction A. This forms a straight discharge water flow S2.

吐水部材１４はさらに、照明部材４０を有する。照明部材４０は、吐水部材１４が形成する吐水流Ｓ１、Ｓ２を照らすための部材（例えばランプ）であり、吐水部材１４に内蔵されている。照明部材４０は例えば配線（図示せず）によって電源（図示せず）に接続されており、点灯制御される。本実施形態の吐水部材１４は、照明部材４０が発する光を外部に通過させるように透明な材料（例えばアクリル）で構成されている。 The water discharge member 14 further has an illumination member 40. The illumination member 40 is a member (e.g., a lamp) for illuminating the water discharge flows S1 and S2 formed by the water discharge member 14, and is built into the water discharge member 14. The illumination member 40 is connected to a power source (not shown), for example, by wiring (not shown), and its lighting is controlled. In this embodiment, the water discharge member 14 is made of a transparent material (e.g., acrylic) that allows the light emitted by the illumination member 40 to pass to the outside.

図５は、吐水部材１４の傾斜面２５の周辺を示す拡大斜視図である。図６は、吐水部材１４の他端２４を平面視した正面図である。 Figure 5 is an enlarged perspective view showing the periphery of the inclined surface 25 of the water discharge member 14. Figure 6 is a front view of the other end 24 of the water discharge member 14 in plan view.

図１～図４では図示を省略したが、図５、図６に示すように、傾斜面２５の端部３０には複数の凹部３２が形成されている。凹部３２は、前述した吐水流Ｓ１に所望の凹凸パターン（テクスチャ模様）を形成するために設けられた形状である。 Although not shown in Figures 1 to 4, as shown in Figures 5 and 6, a number of recesses 32 are formed on the end 30 of the inclined surface 25. The recesses 32 are shaped to form a desired uneven pattern (texture design) in the water discharge flow S1 described above.

複数の凹部３２は、吐水部材１４の周方向Ｒに沿って規則的に配置されている。図６に示すように、本実施形態の凹部３２は周方向Ｒの全周にわたって略等間隔で配置されている。 The multiple recesses 32 are regularly arranged along the circumferential direction R of the water discharge member 14. As shown in FIG. 6, the recesses 32 in this embodiment are arranged at approximately equal intervals around the entire circumference in the circumferential direction R.

複数の凹部３２を配置することにより、傾斜面２５に沿って流れる吐水流Ｓ１が環状の水膜を形成する際に吐水流Ｓ１の表面に所望の凹凸パターンを形成することができる。 By arranging multiple recesses 32, a desired uneven pattern can be formed on the surface of the water discharge flow S1 when the water discharge flow S1 flows along the inclined surface 25 and forms a ring-shaped water film.

吐水流Ｓ１のイメージ図を図７に示す。図７に示すように、吐水流Ｓ１は、所定の凹凸パターンとしてテクスチャ模様を表面に形成する。このようなテクスチャ模様は、凹部３２のそれぞれの端から斜めに延びる稜線３４が互いに交差することで表れる。このようにして、通常とは異なる吐水形態を実現することができる。 Figure 7 shows an image of the water discharge flow S1. As shown in Figure 7, the water discharge flow S1 forms a textured pattern on the surface as a predetermined uneven pattern. Such a textured pattern appears when the ridges 34 extending diagonally from each end of the recess 32 intersect with each other. In this way, a water discharge form that differs from the usual can be realized.

さらに、凹部３２の詳細な形状について、図８～図１０を用いて説明する。 Furthermore, the detailed shape of the recess 32 will be explained using Figures 8 to 10.

図８は、複数の凹部３２を平面視するように傾斜面２５の端部３０を周方向Ｒに展開した展開図である。図８に示すように、凹部３２のそれぞれは周方向Ｒに沿って幅Ｗを有する。本実施形態の凹部３２は、流れ方向Ｆの上流から下流に向かって幅Ｗが漸増する形状を有する。このような形状によれば、凹部３２に沿って流れる水が外側に発散して吐水流Ｓ１における周方向Ｒへの回転成分が生じ、吐水流Ｓ１に所望のテクスチャ模様を形成することができる。 Figure 8 is a development view of the end 30 of the inclined surface 25 developed in the circumferential direction R so that the multiple recesses 32 are viewed in a plan view. As shown in Figure 8, each of the recesses 32 has a width W along the circumferential direction R. The recesses 32 in this embodiment have a shape in which the width W gradually increases from upstream to downstream in the flow direction F. With this shape, the water flowing along the recesses 32 dissipates outward, generating a rotational 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.

さらに本実施形態では、図８に示すように凹部３２の稜線が滑らかな湾曲形状を有している。凹部３２の幅Ｗの漸増率は、流れ方向Ｆの上流から下流に向かって小さくなっている。これにより、凹部３２に沿って流れる水が外側に過剰に発散することを抑制することができ、吐水流Ｓ１に所望のテクスチャ模様を形成することができる。 Furthermore, in this embodiment, as shown in FIG. 8, the ridge of the recess 32 has a smoothly 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. This makes it possible to prevent the water flowing along the recess 32 from dispersing excessively to the outside, and to form a desired texture pattern in the discharged water flow S1.

図８に示すように、凹部３２の幅Ｗの最大値を「最大幅Ｘ」とし、凹部３２どうしの距離を「間隔Ｙ」とすると、本実施形態ではＸ＜Ｙ＜２Ｘの関係が成り立つように設定している。これにより、吐水流Ｓ１のテクスチャ模様における凹凸パターンをバランス良く形成することができる。 As shown in FIG. 8, if the maximum value of the width W of the recesses 32 is the "maximum width X" and the distance between the recesses 32 is the "spacing Y," then in this embodiment, the relationship X<Y<2X is set. This allows the unevenness pattern in the texture design of the water discharge flow S1 to be formed in a well-balanced manner.

図９は、凹部３２を周方向Ｒおよび幅方向Ｐに沿った断面で見たときの断面図である。図９に示すように、凹部３２の断面形状は滑らかに湾曲した円弧形状である。凹部３２における幅方向Ｐの中心位置には最下点３４が位置している。このような円弧状の断面形状を流れ方向Ｆに連続させた形状によって凹部３２が構成される。 Figure 9 is a cross-sectional view of the recess 32 when viewed in a cross section along the circumferential direction R and the width direction P. As shown in Figure 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 continuing such an arc-shaped cross-sectional shape in the flow direction F.

凹部３２の断面形状を滑らかな円弧形状とすることで、凹部３２に沿って流れる水への流路抵抗を減らすことができ、吐水流Ｓ１のテクスチャ模様を安定的に形成することができる。 By making the cross-sectional shape of the recess 32 a smooth arc shape, the flow resistance of the water flowing along the recess 32 can be reduced, and the texture pattern of the discharged water flow S1 can be stably formed.

凹部３２は幅方向Ｐに直交する方向に深さＤを有する。深さＤは、凹部３２の端部から最下点３４に向かって緩やかに漸増し、最下点３４において最大深さＤ１となる。 The recess 32 has a depth D in a direction perpendicular to the width direction P. The depth D increases gradually from the end of the recess 32 toward the lowest point 34, reaching a maximum depth D1 at the lowest point 34.

図１０は、凹部３２の最下点３４を含む領域の吐水部材１４の縦断面図である。図１０に示すように、本実施形態の凹部３２における最下点３４は流れ方向Ｆに連続的に延びる際に直線３６を構成する。このような構成によれば、凹部３２を削り加工等で形成する際に、最下点３４を基準として凹部３２を形成することができ、凹部３２の形状誤差を少なく容易に形成することができる。 Figure 10 is a vertical cross-sectional view of the water discharge member 14 in a region including the lowest point 34 of the recess 32. As shown in Figure 10, the lowest point 34 of the recess 32 in this embodiment forms a straight line 36 when it extends continuously in the flow direction F. With this configuration, when forming the recess 32 by machining or the like, the recess 32 can be formed based on the lowest point 34, and the recess 32 can be easily formed with little shape error.

図１０に示すように、凹部３２は最下点３４における最大深さＤ１が流れ方向Ｆに沿って漸増する形状を有する。これにより、凹部３２に沿って流れる水に関して、吐水部材１４の中心へ向かって内側へ進む速度成分が大きくなり、吐水流Ｓ１の形状がより立体的なものになる。これにより、吐水流Ｓ１に所望のテクスチャ模様を形成することができ、また通常とは異なる吐水形態であることの視認性も向上する。 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, the velocity component of the water flowing along the recess 32 moving inward toward the center of the water discharge member 14 increases, making the shape of the water discharge flow S1 more three-dimensional. This allows the desired texture pattern to be formed in the water discharge flow S1, and also improves visibility of the unusual water discharge form.

図１０に示すように、最下点３４が構成する直線３６と、凹部３２に対して上流側から接続する傾斜面２５の上流側部分３８とは角度θを成している。本実施形態では、角度θを１５０度以上１７５度以下に設定している。これにより、凹部３２に沿って流れる水に関して、吐水部材１４の中心へ向かって内側に進む速度成分を適度に増加させることができ、吐水流Ｓ１に所望のテクスチャ模様を形成することができる。 As shown in FIG. 10, the straight line 36 formed by the lowest point 34 and the upstream portion 38 of the inclined surface 25 that connects to the recess 32 from the upstream side form an angle θ. In this embodiment, the angle θ is set to be greater than or equal to 150 degrees and less than or equal to 175 degrees. This allows the velocity component of the water flowing along the recess 32 that moves inward toward the center of the water discharge member 14 to be appropriately increased, and the desired texture pattern can be formed in the water discharge flow S1.

さらに本実施形態の水栓２では、上述したテクスチャ模様を有する吐水流Ｓ１に加えて、ストレート状の吐水流Ｓ２を組み合わせている。これにより、通常とは異なる吐水形態を実現しながら、水栓２の実用性を向上させることができる。さらには照明部材４０を用いて吐水流Ｓ１、Ｓ２をライトアップすることで、デザイン性を向上させることができる。 Furthermore, in the faucet 2 of this embodiment, in addition to the water discharge flow S1 having the textured pattern described above, a straight water discharge flow S2 is combined. This allows for a water discharge form that is different from the usual one to be realized while improving the practicality of the faucet 2. Furthermore, the design can be improved by lighting up the water discharge flows S1 and S2 using the lighting member 40.

上述したように、本実施形態の水栓２が備える吐水部構造は、第１筒状部材１０と、吐水部材１４と、を備える。第１筒状部材１０は第１内部流路１６を形成し、第１内部流路１６を下流側に開放する開口部２６を有する。吐水部材１４は、一端２２から他端２４に向かって外側に広がるように傾斜した傾斜面２５を有する。吐水部材１４は、第１筒状部材１０の開口部２６に一端２２が挿入され、開口部２６を形成する第１筒状部材１０の内縁部２８と傾斜面２５とが隙間を空けた状態で位置決めされる。第１筒状部材１０の第１内部流路１６を流れる水は、吐水部材１４の傾斜面２５に沿って内縁部２８と傾斜面２５の隙間を通過するように流れ、傾斜面２５の端部３０から離れるように吐水される。傾斜面２５の端部３０には周方向Ｒに間隔を空けて複数の凹部３２が形成される。 As described above, the water discharge section structure of the faucet 2 of this embodiment includes a first tubular member 10 and a water discharge member 14. The first tubular member 10 forms a first internal flow path 16 and has an opening 26 that opens the first internal flow path 16 downstream. The water discharge member 14 has an inclined surface 25 that is inclined so as to spread outward from one end 22 to the other end 24. The water discharge member 14 is positioned with one end 22 inserted into the opening 26 of the first tubular member 10, with a gap between the inner edge 28 of the first tubular member 10 that forms the opening 26 and the inclined surface 25. Water flowing through the first internal flow path 16 of the first tubular member 10 flows along the inclined surface 25 of the water discharge member 14 so as to pass through the gap between the inner edge 28 and the inclined surface 25, and is discharged away from the end 30 of the inclined surface 25. A plurality of recesses 32 are formed at intervals in the circumferential direction R on the end 30 of the inclined surface 25.

このような構成によれば、傾斜面２５の端部３０に複数の凹部３２を設けることで、傾斜面２５の端部３０から吐水される水によって、凹凸パターンを有する吐水流Ｓ１を形成することができ、通常とは異なる吐水形態を実現することができる。 According to this configuration, by providing multiple recesses 32 at the end 30 of the inclined surface 25, the water discharged from the end 30 of the inclined surface 25 can form a water discharge flow S1 having an uneven pattern, thereby realizing a water discharge form different from the usual one.

また本実施形態の水栓２の吐水部構造では、複数の凹部３２のそれぞれは、傾斜面２５の流れ方向Ｆの上流側から下流側に向かって幅Ｗが漸増する。このような構成によれば、凹部３２に沿って流れる水が外側に発散しやすくなって吐水流Ｓ１に回転成分が生じ、所望の凹凸パターンを有する吐水流Ｓ１を形成することができる。 In addition, in the water discharge section structure of the faucet 2 of this embodiment, the width W of each of the multiple recesses 32 gradually increases from the upstream side to the downstream side of the flow direction F of the inclined surface 25. With this configuration, the water flowing along the recesses 32 tends to dissipate outward, creating a rotational component in the water discharge flow S1, and it is possible to form the water discharge flow S1 with the desired unevenness pattern.

また本実施形態の水栓２の吐水部構造では、複数の凹部３２のそれぞれの幅Ｗの増加率は、傾斜面２５の流れ方向Ｆの上流側から下流側に向かって小さくなる。このような構成によれば、凹部３２に沿って流れる水が外側に過剰に発散することを抑制することができる。 In addition, in the water outlet structure of the faucet 2 of this embodiment, the rate of increase in the width W of each of the multiple recesses 32 decreases from the upstream side to the downstream side of the flow direction F of the inclined surface 25. This configuration makes it possible to prevent the water flowing along the recesses 32 from dispersing excessively to the outside.

また本実施形態の水栓２の吐水部構造では、複数の凹部３２のそれぞれは、傾斜面２５の流れ方向Ｆの上流側から下流側に向かって深さＤが漸増する。このような構成によれば、凹部３２に沿って流れる水の中心に向かう速度成分が増して吐水流Ｓ１がより立体的な形状となり、通常とは異なる吐水形態であることの視認性も向上する。 In addition, in the water discharge section structure of the faucet 2 of this embodiment, the depth D of each of the multiple recesses 32 gradually increases from the upstream side to the downstream side of the flow direction F of the inclined surface 25. With this configuration, the velocity component toward the center of the water flowing along the recesses 32 increases, making the discharge flow S1 more three-dimensional, and improving visibility of the unusual water discharge shape.

また本実施形態の水栓２の吐水部構造では、複数の凹部３２のそれぞれは、幅方向Ｐの断面における最下点３４が上流側から下流側に向かって直線状に延びる形状（直線３６）を有する。このような構成によれば、複数の凹部３２を形成する際に最下点３４を基準として形成することができ、凹部３２を容易に形成することができる。 In addition, in the water outlet structure of the faucet 2 of this embodiment, each of the multiple recesses 32 has a shape in which the lowest point 34 in a cross section in the width direction P extends in a straight line (straight line 36) from the upstream side to the downstream side. With this configuration, the multiple recesses 32 can be formed using the lowest point 34 as a reference, making it easy to form the recesses 32.

また本実施形態の水栓２の吐水部構造では、複数の凹部３２のそれぞれにおける幅方向Ｐの断面の最下点３４を流れ方向Ｆに結んだ直線３６と、凹部３２に対して上流側から接続する傾斜面２５の上流側部分３８とが成す角度θは１５０度以上１７５度以下である。このような構成によれば、凹部３２に沿って流れる水の中心に向かう速度成分を適度に増加させることができ、所望の凹凸パターンを有する吐水流Ｓ１を形成することができる。 In addition, in the water outlet structure of the faucet 2 of this embodiment, the angle θ between the straight line 36 connecting the lowest point 34 of the cross section in the width direction P of each of the multiple recesses 32 in the flow direction F and the upstream portion 38 of the inclined surface 25 connecting to the recesses 32 from the upstream side is 150 degrees or more and 175 degrees or less. With this configuration, the velocity component toward the center of the water flowing along the recesses 32 can be appropriately increased, and a water outlet flow S1 with the desired unevenness pattern can be formed.

また本実施形態の水栓２の吐水部構造では、複数の凹部３２のそれぞれは、幅方向Ｐの断面形状が円弧状である。このような構成によれば、凹部３２が滑らかな形状を有することで、凹部３２に沿って水が流れる際に水の流れが乱れることを抑制することができる。 In addition, in the water outlet structure of the faucet 2 of this embodiment, each of the multiple recesses 32 has an arc-shaped cross section in the width direction P. With this configuration, the recesses 32 have a smooth shape, which makes it possible to prevent the flow of water from being disturbed as it flows along the recesses 32.

また本実施形態の水栓２の吐水部構造では、凹部３２の最大幅をＸ、凹部３２どうしの間隔をＹとすると、Ｘ＜Ｙ＜２Ｘの関係を満たす。このような構成によれば、吐水流Ｓ１の凹凸パターンをバランス良く形成することができる。 In addition, in the water discharge section structure of the faucet 2 of this embodiment, if the maximum width of the recesses 32 is X and the distance between the recesses 32 is Y, the relationship X<Y<2X is satisfied. With this configuration, it is possible to form a well-balanced uneven pattern of the water discharge flow S1.

また本実施形態の水栓２の吐水部構造では、傾斜面２５の端部３０は周方向Ｒに環状につながっている。このような構成によれば、吐水流Ｓ１が環状の水膜を形成することができる。 In addition, in the water discharge section structure of the faucet 2 of this embodiment, the end 30 of the inclined surface 25 is connected in a ring shape in the circumferential direction R. With this configuration, the water discharge flow S1 can form a ring-shaped water film.

また本実施形態の水栓２の吐水部構造では、吐水部材１４は、傾斜面２５よりも内側に貫通流路２０を有する。このような構成によれば、傾斜面２５に沿った吐水流Ｓ１と、貫通流路２０を通じた吐水流Ｓ２を形成することができ、異なる２つの吐水形態を実現することができる。 In addition, in the water discharge section structure of the faucet 2 of this embodiment, the water discharge member 14 has a through flow passage 20 inside the inclined surface 25. With this configuration, a water discharge flow S1 along the inclined surface 25 and a water discharge flow S2 through the through flow passage 20 can be formed, realizing two different water discharge forms.

また本実施形態の水栓２の吐水部構造では、吐水部材１４は照明部材４０を内蔵するとともに、透明な材料で構成される。このような構成によれば、吐水流Ｓ１、Ｓ２のデザイン性を向上させることができる。 In addition, in the water discharge section structure of the faucet 2 of this embodiment, the water discharge member 14 incorporates the lighting member 40 and is made of a transparent material. This configuration can improve the design of the water discharge flows S1 and S2.

また本実施形態の水栓２は、上述した構造の吐水部構造を備える。このような構成によれば、吐水部構造と同様の効果を奏することができる。 The faucet 2 of this embodiment also has the water discharge section structure described above. This configuration can achieve the same effects as the water discharge section structure.

なお、本発明は前記実施形態に限定されるものではなく、その他種々の態様で実施できる。例えば、上記実施形態では、環状の吐水流Ｓ１に加えてストレート状の吐水流Ｓ２を形成するように、第２筒状部材１２に第２内部流路１８を設ける場合について説明したが、このような場合に限らない。ストレート状の吐水流Ｓ２を省略して、環状の吐水流Ｓ１のみを形成するようにしてもよい。また、吐水部材１４を第１筒状部材１０に対して位置決めするための取付構造として、第２筒状部材１２とは異なる取付部材を用いてもよい。 The present invention is not limited to the above embodiment, and can be implemented in various other aspects. For example, in the above embodiment, a case was described in which the second internal flow path 18 is provided in the second tubular member 12 so as to form a straight water discharge flow S2 in addition to the annular water discharge flow S1, but this is not limited to the above case. The straight water discharge flow S2 may be omitted, and only the annular water discharge flow S1 may be formed. Also, a mounting member different from the second tubular member 12 may be used as a mounting structure for positioning the water discharge member 14 relative to the first tubular member 10.

また上記実施形態では、図６、図８に示すように、複数の凹部３２を同じ寸法としながら周方向Ｒに等間隔に配置する場合について説明したが、このような場合に限らない。例えば、Ｘ＜Ｙ＜２Ｘの関係を満たすことを条件に、凹部３２の最大幅Ｘや凹部３２どうしの間隔Ｙを凹部３２ごとに変化させてもよい。 In the above embodiment, as shown in Figures 6 and 8, a case has been described in which multiple recesses 32 are arranged at equal intervals in the circumferential direction R while having the same dimensions, but this is not limited to the case. For example, the maximum width X of the recesses 32 or the interval Y between the recesses 32 may be changed for each recess 32, provided that the relationship X<Y<2X is satisfied.

また上記実施形態では、Ｘ＜Ｙ＜２Ｘの関係を満たすように設計する場合について説明したが、このような場合に限らない。例えば、図１１に示すように、Ｙ＜Ｘ＜２Ｙの関係を満たすように設計してもよい。このような場合であっても、吐水流Ｓ１の凹凸パターンをバランス良く形成することができる。 In the above embodiment, the design is described so that the relationship X<Y<2X is satisfied, but this is not the only possible case. For example, as shown in FIG. 11, the design may be such that the relationship Y<X<2Y is satisfied. Even in such a case, the concave-convex pattern of the discharged water flow S1 can be formed in a well-balanced manner.

また上記実施形態では、図６に示すように、傾斜面２５の端部３０が周方向Ｒに環状につながっている場合について説明したが、このような場合に限らない。端部３０は周方向Ｒに部分的に欠けていてもよく、それに応じて、凹部３２が周方向Ｒにおいて部分的に設けられない場合であってもよい。 In the above embodiment, as shown in FIG. 6, the end 30 of the inclined surface 25 is connected in a ring shape in the circumferential direction R, but this is not limited to the above case. The end 30 may be partially missing in the circumferential direction R, and accordingly, the recess 32 may not be provided in part in the circumferential direction R.
