As described above, the water spray plate has a concave shape in the axial direction of the shower head and a convex shape in the vertical direction with respect to the axial direction of the shower head. For this reason, the watering nipple inserted in the watering hole of the watering case is arranged to spread outward from the center of the shower head. Therefore, the water spray range of the shower head has a desired spread.
特許文献1に記載されたシャワーヘッドは、良好なシャワー機能に注目されるが、その使用にともなって水成分中のカルシウムに起因する水垢などの異物で散水プレートの散水ニップルの通水孔に目詰まりが生じることがある。このような場合、シャワーヘッドの組み立てと逆の手順で散水プレートを取り外して異物の除去を行う必要がある。したがって、特許文献1に記載されたシャワーヘッドについては、目詰まり時のメンテナンスが必ずしも容易ではないという問題が指摘される。
Although the shower head described in Patent Document 1 is noted for a good shower function, the use of the shower head causes a foreign matter such as scales due to calcium in the water component to be observed in the water passage hole of the watering nipple of the watering plate.

Further, the shower head described in Patent Document 1 is limited to a cylindrical shower head. Therefore, it is not possible to use a shower head of another shape to meet the design requirement.
さらにまた、散水プレートを特殊な形状を有するものに成形する必要がある。つまり、散水プレートの表面は、上記のとおり、シャワーヘッドの軸方向を凹形状に形成され、かつシャワーヘッドの軸方向に対して垂直方向を凸形状に形成されなければならない。したがって、特許文献1に記載されたシャワーヘッドについては、散水プレートは弾性体から形成されるものではあるが、表面には通水孔を有する散水ニップルが複数設けられるので、散水プレートの設計と製造は必ずしも容易ではないという問題が指摘される。
Furthermore, it is necessary to mold the watering plate into a special shape. That is, as described above, the surface of the watering plate must be formed in a concave shape in the axial direction of the shower head and in a convex shape in a direction perpendicular to the axial direction of the shower head. Therefore, for the shower head described in Patent Document 1, the watering plate is formed of an elastic body, but since the surface is provided with a plurality of watering nipples having water passage holes, the design and manufacture of the watering plate It is pointed out that this is not always easy.

As shown in FIGS. 2 (a) to 2 (c), the water spray plate 4 has a flat plate portion 15 of a size that fits within the peripheral wall portion 11 provided on the back surface of the head cover 3 with almost no gap as a plate-like portion. Have. The shape of the flat plate portion 15 is the same as a snowman shape in plan view as the peripheral wall portion 11. Further, the flat plate portion 15 has a uniform thickness throughout, and the thickness is within the height of the peripheral wall portion 11. Here, the uniform thickness may include a manufacturing error. For example, in the flat plate portion 15 as a plate-like portion, the difference between the thickness of the thickest portion and the thickness of the thinnest portion is an error of about 10% of the thickness of the thickest portion. Permissible. On the surface 15 a of the flat plate portion 15, a plurality of watering protrusions 16 having a cylindrical shape are erected. The outer diameter of the sprinkling protrusion 16 is substantially the same as the inner diameter of the sprinkling hole 10 formed in the sprinkling part 9 of the head cover 3, and the sprinkling protrusion 16 is the same as the arrangement of the sprinkling holes 10 in the sprinkling part 9 of the head cover 3. It is said that. That is, the sprinkling projections 16 are provided on the surface 15a of the flat plate portion 15 as two rows on the inner side and the outer side, and the row of the sprinkling projections 16 located on the inner side and the row of the sprinkling projections 16 located on the outer side are arranged concentrically. Has been. Accordingly, each of the water spray protrusions 16 can be inserted into each of the water spray holes 10. Moreover, the projection length of the water sprinkling protrusion 16 has a length exceeding a certain amount of the thickness of the plate-like portion 8 in which the corresponding water sprinkling hole 10 is formed. That is, the plurality of water spray protrusions 16 provided on the flat plate portion 15 are formed with different protrusion lengths according to the surface shape of the plate-like portion 8 of the head cover 3 corresponding to the arrangement position. The protrusion length of the water spray protrusion 16 can be defined as the length from the surface 15a of the flat plate portion 15 to the tip of the water spray protrusion 16. A portion of the sprinkling protrusion 16 that protrudes outward from the surface 8 a of the plate-like portion 8 is formed as the foreign matter removing portion 12 as described later.
また、散水突起16は、先端に吐出孔17を有し、散水プレート4では、図3(b)(c)に示したように、吐出孔17から平板部15の裏面15bまで貫通する湯水の吐出流路18が形成されている。吐出流路18において平板部15の裏面側に位置する部分の内径は、平板部15の裏面15bに向かうにしたがって拡大され、拡径部19を形成している。拡径部19によって、湯水を吐出流路18の内部に導入しやすくしている。このような散水プレート4は、たとえば、ゴムや軟質の樹脂などから形成することができ、弾性を有している。
Moreover, the water spray protrusion 16 has a discharge hole 17 at the tip, and in the water spray plate 4, as shown in FIGS. 3B and 3C, hot water penetrating from the discharge hole 17 to the back surface 15 b of the flat plate portion 15. A discharge flow path 18 is formed. The inner diameter of the portion located on the back surface side of the flat plate portion 15 in the discharge flow path 18 is enlarged toward the back surface 15 b of the flat plate portion 15, thereby forming the expanded diameter portion 19. The enlarged diameter portion 19 makes it easy to introduce hot water into the discharge flow path 18. Such a watering plate 4 can be formed from rubber | gum, soft resin, etc., for example, and has elasticity.
図1(b)(c)に示したように、散水プレート4は、散水突起16の一つずつをヘッドカバー3の散水部9に形成された散水孔10の各一つに挿入してヘッドカバー3の裏面に取り付けられる。取付状態では、散水プレート4の平板部15の表面15aはヘッドカバー3の板状部8の裏面8bに重なり合い、しかも散水プレート4は弾性を有しているので、平板部15が周壁部11の内側にほぼ隙間なく嵌り込む。硬質のヘッドカバー3と散水プレート4の弾性とによって、散水プレート4のヘッドカバー3への取付状態は安定に保持される。湯水の吐出の際に水圧が加わっても、散水プレート4の取付位置にずれが生じるのが抑制される。また、取付状態では、散水孔10に挿入された散水突起16の先端部が、ヘッドカバー3の板状部8の表面8aから外側に突出し、この突出部分が異物除去部12を形成する。異物除去部12を形成する散水突起16の突出部分の長さは、複数の散水突起16ともに均一とされている。このように、突出部分の長さが板状部8の表面全体において均一化されているので、ヘッドカバー3の表面のデザインが損なわれにくくなり、良好な外観を有するシャワーヘッド1を得る。ここで、散水突起16の突出部分の長さが均一とは、すべての散水突起16の突出部分の長さが同じという意味に限定して解釈されるものではない。ヘッドカバー3の表面のデザインが損なわれない程度の、散水突起16間での突出部分の長さのバラツキも許容される。たとえば、突出部分の長さが最も長い散水突起16の突出部分の長さと、突出部分の長さが最も短い散水突起16の突出部分の長さとの差が、突出部分の長さが最も長い散水突起16の突出部分の長さの10%以内となっているバラツキも許容される。なお、突出部分の長さは、散水孔10が形成されている箇所の板状部8の仮想表面の散水孔10の中心から散水突起16の長さ方向先端までの長さと定義することができる。
As shown in FIGS. 1B and 1C, the water spray plate 4 is formed by inserting each water spray protrusion 16 into each one of the water spray holes 10 formed in the water spray portion 9 of the head cover 3. It is attached to the back of the. In the mounted state, the surface 15 a of the flat plate portion 15 of the water spray plate 4 overlaps the back surface 8 b of the plate-like portion 8 of the head cover 3, and the water spray plate 4 has elasticity, so that the flat plate portion 15 is inside the peripheral wall portion 11. Fits almost without gaps. The mounting state of the water spray plate 4 to the head cover 3 is stably maintained by the rigid head cover 3 and the elasticity of the water spray plate 4. Even if water pressure is applied during the discharge of hot water, it is possible to suppress the displacement of the attachment position of the water spray plate 4. Further, in the mounted state, the tip end portion of the water spray protrusion 16 inserted into the water spray hole 10 protrudes outward from the surface 8 a of the plate-like portion 8 of the head cover 3, and this protrusion portion forms the foreign matter removing portion 12. The length of the protruding portion of the sprinkling protrusion 16 that forms the foreign matter removing portion 12 is uniform for the plurality of sprinkling protrusions 16. As described above, since the length of the protruding portion is made uniform over the entire surface of the plate-like portion 8, the design of the surface of the head cover 3 is unlikely to be damaged, and the shower head 1 having a good appearance is obtained. Here, the uniform length of the protruding portions of the sprinkling protrusions 16 is not construed as being limited to the meaning that the lengths of the protruding portions of all the sprinkling protrusions 16 are the same. Variations in the length of the protruding portion between the water sprinkling protrusions 16 to such an extent that the design of the surface of the head cover 3 is not impaired are allowed. For example, the difference between the length of the protruding portion of the sprinkling protrusion 16 having the longest protruding portion length and the length of the protruding portion of the sprinkling protrusion 16 having the shortest protruding portion length is the water sprinkling length of the protruding portion. Variations within 10% of the length of the protruding portion of the protrusion 16 are also allowed. The length of the protruding portion can be defined as the length from the center of the water spray hole 10 on the virtual surface of the plate-like portion 8 where the water spray hole 10 is formed to the tip of the water spray protrusion 16 in the length direction. .
ヘッドカバー3は、そのように散水プレート4が板状部8の裏面8bに取り付けられた状態において、ヘッド本体2の表面側に取り付けられる。その取り付けは、嵌合、ビスなどの固着具を用いた固着などによって実現可能であり、Oリングなどを介在させることによって水密性を高めることもできる。取付状態では、ヘッド本体2の流路形成部30の側壁部31が周壁部11の内側にほぼ隙間なく嵌り込む。また、散水プレート4の平板部15の裏面15bが押さえ部35を構成する周壁部33および支持部34の先端部で押さえ付けられる。これによって、散水プレート4の平板部15の表面15aがヘッドカバー3の板状部8の裏面8bに密着し、散水プレート4をより安定して保持することができる。こうして散水プレート4のヘッドカバー3への取付状態をより確実なものとすることができる。
The head cover 3 is attached to the front surface side of the head body 2 in such a state that the watering plate 4 is attached to the back surface 8b of the plate-like portion 8. The attachment can be realized by fitting, fixing using a fixing tool such as a screw, and the like, and watertightness can be enhanced by interposing an O-ring or the like. In the mounted state, the side wall portion 31 of the flow path forming portion 30 of the head main body 2 is fitted inside the peripheral wall portion 11 with almost no gap. Further, the back surface 15 b of the flat plate portion 15 of the water spray plate 4 is pressed by the peripheral wall portion 33 constituting the pressing portion 35 and the distal end portion of the support portion 34. Thereby, the surface 15a of the flat plate portion 15 of the water spray plate 4 is in close contact with the back surface 8b of the plate-like portion 8 of the head cover 3, and the water spray plate 4 can be held more stably. Thus, the attachment state of the water spray plate 4 to the head cover 3 can be made more reliable.
取付状態では、また、散水プレート4の平板部15の裏面15bと押さえ部35との当接によって、ヘッド本体2の平板部32の表面32aと散水プレート4の平板部15の裏面15bとの間に、湯水の流入流路14が形成される。流入流路14は、流出孔6および流出流路7を通じて導入流路5と連通する。吐出流路18は、拡径部19を通じて流入流路14と連通し、ヘッド本体2の導入流路5が、各散水突起16の吐出孔17と連通する。したがって、シャワーヘッド1は、導入流路5に導入された湯水を各吐出孔17からシャワーとして噴出することができる。
In the mounted state, the contact between the back surface 15b of the flat plate portion 15 of the water spray plate 4 and the pressing portion 35 causes the surface 32a of the flat plate portion 32 of the head main body 2 and the back surface 15b of the flat plate portion 15 of the water spray plate 4 to contact each other. In addition, a hot water inflow channel 14 is formed. The inflow channel 14 communicates with the introduction channel 5 through the outflow hole 6 and the outflow channel 7. The discharge flow path 18 communicates with the inflow flow path 14 through the enlarged diameter portion 19, and the introduction flow path 5 of the head body 2 communicates with the discharge holes 17 of the water spray protrusions 16. Therefore, the shower head 1 can eject the hot water introduced into the introduction flow path 5 from each discharge hole 17 as a shower.
シャワーヘッド1の使用にともなって水成分中のカルシウムなどに起因する水垢などの異物で散水突起16の吐出流路18に目詰まりが生じることがある。このような場合、板状部8の表面8aから外側に突出している散水突起16を指でこするなどして異物除去部12に外力を与えて弾性変形させることによって、異物を取り出したり破砕したりする。こうして、シャワーヘッド1を分解して散水プレート4を取り外さなくても、異物の除去を容易に行うことができる。また、吐出孔17の周辺、たとえばヘッドカバー3の散水孔10内にも異物が付着し、蓄積することがある。この場合も散水突起16を指でこするなどして異物除去部12に外力を付与して弾性変形させることで、また散水突起16を介して散水プレート4を弾性変形させることで、異物を取り出したり破砕したりするなど異物の除去を容易に行うことができる。このように散水突起16はヘッドカバー3の板状部8の表面8aから外側に突出する長さを有し、その突出部分が異物除去部12を形成しているので、目詰まり時などのメンテナンスが容易である。ここで、異物除去部12は、0.5~2mmの長さを有していることが好ましい。かかる長さを有する異物除去部12は、異物の除去をより容易に行うことができる。また、湯水の吐出の際に水圧が加わってもその突出部分のぶれを抑制することができ、より安定して所定の範囲に散水することができる。さらにまた、ヘッドカバー3の表面のデザインに与える影響が小さく、より良好な外観を有するシャワーヘッド1を得ることができる。
As the shower head 1 is used, clogging may occur in the discharge flow path 18 of the sprinkling protrusions 16 due to foreign matters such as scale caused by calcium in the water component. In such a case, the foreign matter is removed or crushed by applying an external force to the foreign matter removing portion 12 by elastically deforming the foreign matter removing portion 12 by, for example, rubbing the watering projection 16 protruding outward from the surface 8a of the plate-like portion 8 with a finger. Or In this way, foreign matter can be easily removed without disassembling the shower head 1 and removing the watering plate 4. In addition, foreign matter may adhere to and accumulate in the vicinity of the discharge hole 17, for example, in the water spray hole 10 of the head cover 3. Also in this case, the foreign matter can be taken out by applying an external force to the foreign matter removing portion 12 by elastically deforming it by rubbing the sprinkling projection 16 with a finger or by elastically deforming the water spray plate 4 through the sprinkling projection 16. It is possible to easily remove foreign matters such as crushing or crushing. Thus, the sprinkling protrusion 16 has a length that protrudes outward from the surface 8a of the plate-like portion 8 of the head cover 3, and the protruding portion forms the foreign matter removing portion 12, so that maintenance such as clogging can be performed. Easy. Here, the foreign substance removing unit 12 preferably has a length of 0.5 to 2 mm. The foreign substance removing unit 12 having such a length can more easily remove foreign substances. Moreover, even if a water pressure is applied during the discharge of hot water, it is possible to suppress blurring of the protruding portion, and water can be sprayed more stably within a predetermined range. Furthermore, it is possible to obtain the shower head 1 that has a small influence on the surface design of the head cover 3 and has a better appearance.
また、ヘッドカバー3の板状部8の表面8aは凸曲面形状、凹曲面形状、凹凸曲面形状など様々な表面形状に対応可能に曲面形状を有しているので、デザイン上の要請に応えることができる。したがって、特許文献1に記載されるように円筒形状のシャワーヘッドに限定されず、様々な形状に設計可能であり、汎用性に富む。しかも、ヘッドカバー3の板状部8の表面8aから外側に突出する散水突起16の突出部分の長さが均一化されているので、ヘッドカバー3の表面のデザインが損なわれず、良好な外観を有するシャワーヘッド1を得ることができる。
Further, since the surface 8a of the plate-like portion 8 of the head cover 3 has a curved surface shape that can correspond to various surface shapes such as a convex curved surface shape, a concave curved surface shape, and a concave and convex curved surface shape, it can meet a design requirement. it can. Therefore, it is not limited to a cylindrical shower head as described in Patent Document 1, and can be designed in various shapes, and is versatile. Moreover, since the length of the protruding portion of the sprinkling protrusion 16 protruding outward from the surface 8a of the plate-like portion 8 of the head cover 3 is made uniform, the design of the surface of the head cover 3 is not impaired and the shower has a good appearance. The head 1 can be obtained.
そして、散水プレート4の平板部15は均一な厚さを有しているので、散水プレート4の設計と製造が容易となる。このような平板部15の厚さが均一である散水プレート4は表面形状が異なる各種のヘッドカバー3と組み合わせて使用可能であり、シャワーヘッド1の設計と製造が容易である。
Since the flat plate portion 15 of the watering plate 4 has a uniform thickness, the watering plate 4 can be easily designed and manufactured. The water spray plate 4 having a uniform thickness of the flat plate portion 15 can be used in combination with various head covers 3 having different surface shapes, and the shower head 1 can be easily designed and manufactured.
図4は、本発明の別の一実施形態であるシャワーヘッドのヘッドカバーの散水孔周辺を拡大して示した断面図である。図4では、図1-図3に示した実施形態と同じ部分には同一の符号を付し、その説明を省略する。
FIG. 4 is an enlarged cross-sectional view of the vicinity of a water spray hole of a head cover of a shower head according to another embodiment of the present invention. 4, the same parts as those in the embodiment shown in FIGS. 1 to 3 are denoted by the same reference numerals, and the description thereof is omitted.
シャワーヘッド50は、ヘッドカバー51の散水部9に形成された散水孔10の側面21の一部を内側に傾斜させることもできる。側面21の傾斜は、散水孔10に挿入され、ヘッドカバー51の板状部8の表面から外側に突出する散水突起16が、下流側に向かって散水部9の外側方、すなわち、ヘッドカバー51の外側に傾斜する向きとされている。このような側面21の傾斜によって散水突起16の配置が規制される。側面21の傾斜は、散水孔10のすべてまたは一部に設けることができる。シャワーヘッド50では、散水孔10の側面21の一部が上記のとおりに傾斜しているので、散水孔10に挿入される散水突起16が、側面21の傾斜方向に傾き、配置が規制される。このため、図4に示したように、散水突起16の吐出孔17から吐出する湯水の散水範囲Rが、ヘッドカバー51の外側方に広がる。したがって、シャワーヘッド50は、比較的小型のものであっても、シャワー機能に必要とされる散水範囲Rを実現することができる。しかもヘッドカバー51は、硬質であり、製造上の寸法精度が高いため、弾性を有する散水プレート4の寸法にばらつきが生じても、そのばらつきにあまり影響されずに散水範囲Rの拡大を安定して実現することができる。
The shower head 50 can also incline a part of the side surface 21 of the watering hole 10 formed in the watering part 9 of the head cover 51 inward. The slope of the side surface 21 is inserted into the water spray hole 10, and the water spray protrusion 16 protruding outward from the surface of the plate-like portion 8 of the head cover 51 is located outward of the water spray portion 9 toward the downstream side, that is, outside the head cover 51. It is said that the direction is inclined. Such an inclination of the side surface 21 regulates the arrangement of the sprinkling protrusions 16. The inclination of the side surface 21 can be provided in all or part of the water spray hole 10. In the shower head 50, since a part of the side surface 21 of the water spray hole 10 is inclined as described above, the water spray protrusion 16 inserted into the water spray hole 10 is inclined in the inclination direction of the side surface 21, and the arrangement is restricted. . For this reason, as shown in FIG. 4, the sprinkling range R of hot water discharged from the discharge holes 17 of the sprinkling protrusions 16 extends outward of the head cover 51. Therefore, even if the shower head 50 is comparatively small, the watering range R required for the shower function can be realized. Moreover, since the head cover 51 is hard and has high dimensional accuracy in manufacturing, even if the dimensions of the sprinkling plate 4 having elasticity vary, the expansion of the sprinkling range R can be stably performed without being greatly affected by the variation. Can be realized.
なお、散水孔10の側面21の傾斜は、たとえば、図4に示したように、散水孔10の内側に突出する突起22によって形成することができる。突起22により側面21の傾斜が容易に形成される。突起22の形状については、散水孔10の内周に沿った弧状または弓形などが例示される。
In addition, the inclination of the side surface 21 of the water sprinkling hole 10 can be formed by the protrusion 22 which protrudes inside the sprinkling hole 10, for example, as shown in FIG. The protrusion 22 can easily form the slope of the side surface 21. Examples of the shape of the protrusion 22 include an arc shape or an arc shape along the inner periphery of the water spray hole 10.
シャワーヘッド50では、ヘッドカバー51の散水部9の外側に位置する列の散水孔10の側面21の傾斜角θ1と、散水部9の内側に位置する列の散水孔10の側面21の傾斜角θ2とを異なる大きさの角度とすることができる。シャワーヘッド50では、傾斜角θ1が傾斜角θ2よりも大きくなっている。すなわち、θ1>θ2の関係としている。このように、θ1>θ2の関係となるように散水孔10の側面21の傾斜を設定することによって、図4に示した散水範囲Rを拡大しつつ、散水部9の内側に位置する散水突起16の吐出孔17から吐出する湯水の量を確保することができる。シャワーヘッド50を使用する使用者に心地よいシャワー感を与えることができ、しかも、シャワーによる洗浄力を高めるのに有効となる。傾斜角θ1、θ2の大きさは、シャワーヘッド50の大きさや具体的な用途、また、散水突起16の突起長さなどに応じて適宜決定することができる。
In the shower head 50, the inclination angle θ <b> 1 of the side surface 21 of the sprinkling hole 10 located outside the sprinkling part 9 of the head cover 51, and the inclination angle θ <b> 2 of the side face 21 of the sprinkling hole 10 located inside the sprinkling part 9. Can be angles of different sizes. In the shower head 50, the inclination angle θ1 is larger than the inclination angle θ2. That is, the relation θ1> θ2 is established. In this way, by setting the inclination of the side surface 21 of the water spray hole 10 so as to satisfy the relationship of θ1> θ2, the water spray protrusion located inside the water sprinkling part 9 while expanding the water spray range R shown in FIG. The amount of hot water discharged from the 16 discharge holes 17 can be secured. A comfortable shower feeling can be given to the user who uses the shower head 50, and it is effective in enhancing the cleaning power by the shower. The magnitudes of the inclination angles θ1 and θ2 can be appropriately determined according to the size and specific application of the shower head 50, the projection length of the water spray projection 16, and the like.
