Description

本発明は、水栓、特に、水栓における吐水ヘッドの着脱構造に関する。   The present invention relates to a faucet, and more particularly to a structure for attaching and detaching a water discharge head in a faucet.

水栓本体と水栓の先端部分である吐水ヘッドとが別部品として構成され、吐水ヘッドが交換可能である水栓が知られている。例えば、特許文献１には水栓本体である吐水管ボディに対して吐水ヘッドである吐水管が着脱自在に構成された水栓が記載されている。   A faucet is known in which a faucet body and a water discharge head that is the tip of the water faucet are configured as separate parts, and the water discharge head can be replaced. For example, Patent Literature 1 describes a water faucet in which a water discharge pipe as a water discharge head is detachably attached to a water discharge pipe body as a water faucet body.

特開２００２−８１１０８号公報JP 2002-81108 A

ところで、特許文献１に記載の水栓では、吐水管の後端部が吐水管ボディ内の吐水用エルボに結合されると共に吐水管が吐水管ボディに支持されている。具体的には、Ｏリングがはめ込まれた環状溝と、環状突起と、一対の突起爪と、を有する吐水管が、その後端部を吐水管ボディの挿入穴から挿入して吐水用エルボの係止穴部に当接する。このとき、一対の突起爪が吐水管ボディの挿入穴のまわりを挟むことで吐水管が吐水管ボディに支持され、環状突起が連通穴の周囲に当接することで後端部が吐水用エルボの係止穴部に当接する。そして、Ｏリングが係止穴部の内周面に嵌まることでシール状態を確保する。このような構成により、吐水管は吐水用エルボに支持されている。   By the way, in the faucet described in Patent Document 1, the rear end portion of the water discharge pipe is coupled to the water discharge elbow in the water discharge pipe body, and the water discharge pipe is supported by the water discharge pipe body. Specifically, a water discharge pipe having an annular groove in which an O-ring is fitted, an annular protrusion, and a pair of protrusion claws is inserted into the water discharge pipe body through the insertion hole of the water discharge pipe body. Contact the blind hole. At this time, a pair of protruding claws sandwich the circumference of the insertion hole of the water discharge pipe body so that the water discharge pipe is supported by the water discharge pipe body, and an annular protrusion abuts around the communication hole so that the rear end portion of the water discharge elbow Abuts on the locking hole. And an O-ring fits in the inner peripheral surface of a locking hole part, and a sealing state is ensured. With such a configuration, the water discharge pipe is supported by the water discharge elbow.

しかし、特許文献１に記載の水栓では、吐水用エルボに密着している吐水管を外す際、吐水管や吐水用エルボ内に残っていた水が吐水管ボディ内で漏水する虞がある。また、再装着する際に、水栓本体部である吐水管ボディ内で吐水管を吐水用エルボに接続することになるが、この際に、これらの接続部が十分に密着しなかった場合に、吐水管ボディ内でこれらの接続部から漏水するおそれがある。水栓本体内で漏水すると、発見が遅れることと、シンク外の本来乾燥しているべき領域に水が侵入するから、漏水によるダメージが大きくなることがある。このように従来の水栓には、水栓本体部内での漏水の可能性を小さくする観点から改善する余地があった。   However, in the faucet described in Patent Document 1, when the water discharge pipe that is in close contact with the water discharge elbow is removed, water remaining in the water discharge pipe or the water discharge elbow may leak in the water discharge pipe body. Also, when reattaching, the water discharge pipe will be connected to the water discharge elbow in the water discharge pipe body which is the faucet body, but at this time, if these connection parts do not adhere sufficiently There is a risk of water leaking from these connections in the water discharge pipe body. If water leaks within the faucet body, discovery may be delayed, and water may enter the area that should be dried outside the sink, which may increase damage caused by water leakage. Thus, the conventional faucet has room for improvement from the viewpoint of reducing the possibility of water leakage in the faucet body.

本発明の目的は、このような課題に鑑みてなされたもので、吐水ヘッドが交換可能で、水栓本体部内での漏水の可能性を小さくすることが可能な水栓の技術を提供することにある。   An object of the present invention is made in view of such a problem, and provides a faucet technology in which a water discharge head can be replaced and the possibility of water leakage in the faucet main body can be reduced. It is in.

上記課題を解決するために、本発明のある態様の水栓は、通水部材と、通水部材を覆うハウジングを有する水栓本体部と、水栓本体部に着脱可能に装着される吐水ヘッドと、を備える。通水部材と吐水ヘッドとを連通させ、水栓本体部から突出して設けられる筒状部材を有する。   In order to solve the above problems, a faucet according to an aspect of the present invention includes a water faucet member, a faucet body portion having a housing that covers the water passage member, and a water discharge head that is detachably attached to the faucet body portion. And comprising. A water-permeable member and a water discharge head are communicated with each other, and a tubular member is provided that protrudes from the faucet body.

この態様によると、通水部材と吐水ヘッドを連通させ、水栓本体部から突出して設けられる筒状部材を有するから、吐水ヘッドを外したときにも、筒状部材の上流側の端部は水栓本体部内部の通水部材に接続したままの状態であるため、水栓本体部内部での漏水のおそれを小さくすることができる。   According to this aspect, since the water passage member and the water discharge head are communicated with each other and the tubular member is provided so as to protrude from the faucet main body, the upstream end of the tubular member is also removed when the water discharge head is removed. Since it is in the state still connected to the water flow member inside a faucet main-body part, the possibility of the water leak inside a faucet main-body part can be made small.

本発明の別の態様は、吐水ヘッドである。この吐水ヘッドは、水栓本体部に着脱可能に装着される吐水ヘッドであって、吐水ヘッドは、水栓本体部の側面から突出する突出管部を収容する収容部を有する。突出管部は継手管と、継手管に挿入され一部が露出する筒状部材と、を含む。収容部は、筒状部材を環囲する第１収容部と、継手管を環囲する第２収容部と、を有する。   Another aspect of the present invention is a water discharge head. The water discharge head is a water discharge head that is detachably attached to the faucet body, and the water discharge head has an accommodating portion that accommodates a protruding tube portion protruding from the side surface of the faucet body. The protruding pipe portion includes a joint pipe and a cylindrical member that is inserted into the joint pipe and a part of which is exposed. The housing portion includes a first housing portion that surrounds the tubular member, and a second housing portion that surrounds the joint pipe.

この態様によると、収容部が、突出管部の筒状部材を環囲する第１収容部と継手管を環囲する第２収容部とを有することで、収容部が二段構造になるから、第１収容部と筒状部材の間にシールを形成して水漏れを抑制し、第２収容部で継手管を環囲することにより半径方向のガタを抑制することができる。   According to this aspect, since the housing portion has the first housing portion surrounding the cylindrical member of the protruding tube portion and the second housing portion surrounding the joint pipe, the housing portion has a two-stage structure. A seal is formed between the first housing part and the tubular member to suppress water leakage, and by surrounding the joint pipe with the second housing part, radial play can be suppressed.

本発明によれば、吐水ヘッドが交換可能で、水栓本体部内での漏水の可能性を小さくすることが可能な水栓の技術を提供することができる。   ADVANTAGE OF THE INVENTION According to this invention, the water faucet technique which can replace the water discharge head and can reduce the possibility of water leakage in the faucet body can be provided.

図１は、本発明の実施形態に係る水栓１００の側面図であり、図２は水栓１００の分解斜視図である。水栓１００は、一般ユーザでも交換可能な着脱構造を備えている。図１に示す吐水ヘッド１０６は浄水機能を持たないタイプである。以下、ＸＹＺ直交座標系をもとに説明する。方向Ｘは水平な左右方向に対応し、方向Ｙは水平な前後方向に対応し、方向Ｚは鉛直な上下方向に対応する。方向Ｙおよび方向Ｚはそれぞれ方向Ｘに直交する。方向Ｘは左方向あるいは右方向と、方向Ｙは前方向あるいは後方向と、方向Ｚは上方向あるいは下方向と表記することがある。図１において水栓１００を矢印Ｐの方向から視て向かって右側を右と、左側を左という。   FIG. 1 is a side view of a faucet 100 according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view of the faucet 100. The faucet 100 has a detachable structure that can be replaced even by general users. The water discharge head 106 shown in FIG. 1 is a type that does not have a water purification function. Hereinafter, description will be made based on the XYZ orthogonal coordinate system. The direction X corresponds to the horizontal left-right direction, the direction Y corresponds to the horizontal front-rear direction, and the direction Z corresponds to the vertical up-down direction. The direction Y and the direction Z are orthogonal to the direction X, respectively. The direction X may be described as the left direction or the right direction, the direction Y may be expressed as the forward direction or the rear direction, and the direction Z may be expressed as the upward direction or the downward direction. In FIG. 1, when the faucet 100 is viewed from the direction of arrow P, the right side is referred to as right and the left side is referred to as left.

水栓１００は、図２に示すように、本体側面から突出する突出管部２０を有する水栓本体部１１２と、水栓本体部１１２に着脱可能に装着される吐水ヘッド１０６と、を含む。突出管部２０は、継手管１１８と、継手管１１８に挿入され一部が軸方向に突出して露出している筒状部材１７２と、を含み、吐水ヘッド１０６は、突出管部２０を収容する収容部１０を有する。継手管１１８と筒状部材１７２については後述する。   As shown in FIG. 2, the faucet 100 includes a faucet body portion 112 having a protruding tube portion 20 projecting from the side surface of the body, and a water discharge head 106 that is detachably attached to the faucet body portion 112. The protruding pipe part 20 includes a joint pipe 118 and a cylindrical member 172 that is inserted into the joint pipe 118 and is partially exposed in the axial direction, and the water discharge head 106 accommodates the protruding pipe part 20. It has the accommodating part 10. The joint pipe 118 and the cylindrical member 172 will be described later.

（水栓本体部）
水栓本体部１１２は、図１に示すように、通水部材８４と、ハウジング８６と、吐水ハンドル１０２と、を含む。通水部材８４は、接続継手８２、支柱部１０８および通水管１１０を含む。ハウジング８６は、突出管部２０、回転部１０４および支柱キャップ１１４を含む。突出管部２０は本体側面である回転部１０４から半径方向、好ましくは斜め上方に突出する。以下、突出管部２０の中心軸Ｍに沿った方向を軸方向と、中心軸Ｍに直交する方向を半径方向という。 (Water faucet body)
As shown in FIG. 1, the faucet body portion 112 includes a water passage member 84, a housing 86, and a water discharge handle 102. The water flow member 84 includes a connection joint 82, a support column 108, and a water flow pipe 110. The housing 86 includes the protruding tube portion 20, the rotating portion 104, and the support cap 114. The protruding tube portion 20 protrudes in the radial direction, preferably obliquely upward, from the rotating portion 104 which is the side surface of the main body. Hereinafter, the direction along the central axis M of the protruding tube portion 20 is referred to as an axial direction, and the direction orthogonal to the central axis M is referred to as a radial direction.

支柱部１０８は、台所などに固定され、通水管１１０を内蔵する。支柱部１０８を覆うように回転部１０４が設置される。回転部１０４は、支柱部１０８を中心として水平方向に回転する。回転部１０４は、樹脂メッキ加工が施され、外表面に金属光沢を有するメッキ面が設けられる。支柱キャップ１１４は、回転部１０４の上側に設けられ、支柱部１０８と接続される。回転部１０４は、支柱キャップ１１４によって上下に抜けないように位置決めされる。ユーザが支柱キャップ１１４の上にある吐水ハンドル１０２を垂直方向に動かすと、吐水ハンドル１０２は操作突起１１６を前後させ、これによって支柱部１０８に内蔵される弁（不図示）が開閉される。   The support column 108 is fixed to a kitchen or the like and incorporates a water conduit 110. The rotating unit 104 is installed so as to cover the column unit 108. The rotating unit 104 rotates in the horizontal direction around the column unit 108. The rotating part 104 is subjected to resin plating, and a plating surface having a metallic luster is provided on the outer surface. The support cap 114 is provided on the upper side of the rotating unit 104 and is connected to the support unit 108. The rotating unit 104 is positioned by the support cap 114 so as not to be pulled up and down. When the user moves the water discharge handle 102 on the column cap 114 in the vertical direction, the water discharge handle 102 moves the operation protrusion 116 back and forth, thereby opening and closing a valve (not shown) built in the column portion 108.

（突出管部）
突出管部２０は、図２に示すように、継手管１１８と筒状部材１７２とを含む。継手管１１８は回転部１０４から連なって突出する管状の部分である。筒状部材１７２は継手管１１８の内側に差し込まれ、通水口１２４を介して接続継手８２と接続される。接続継手８２は弁を介して通水管１１０と接続される。吐水ヘッド１０６は突出管部２０を収容した状態で、回転部１０４に着脱可能に装着される。図１に示すように、吐水ヘッド１０６の端部は回転部１０４の側面部（外周面）と対向する。すなわち、回転部１０４から継手管１１８が分岐する箇所である継手管１１８の根元において、吐水ヘッド１０６と回転部１０４（水栓本体部１１２）が対向する。 (Protruding tube)
As shown in FIG. 2, the protruding pipe portion 20 includes a joint pipe 118 and a cylindrical member 172. The joint pipe 118 is a tubular part protruding from the rotating part 104. The cylindrical member 172 is inserted inside the joint pipe 118 and connected to the connection joint 82 via the water passage 124. The connection joint 82 is connected to the water conduit 110 through a valve. The water discharge head 106 is detachably attached to the rotating portion 104 in a state where the protruding tube portion 20 is accommodated. As shown in FIG. 1, the end of the water discharge head 106 faces the side surface (outer peripheral surface) of the rotating unit 104. That is, at the base of the joint pipe 118 where the joint pipe 118 branches from the rotating part 104, the water discharge head 106 and the rotating part 104 (the faucet body part 112) face each other.

吐水ヘッド１０６は突出管部２０を収容する収容部１０を含む。吐水ヘッド１０６は、装着時には継手管１１８の根元部分まで収容する。吐水ヘッド１０６は、回転部１０４の外側面と当接することが望ましいが、少なくとも、回転部１０４と吐水ヘッド１０６の接合部分が目立たない程度に回転部１０４の外側面と近接する。   The water discharge head 106 includes the accommodating portion 10 that accommodates the protruding tube portion 20. The water discharge head 106 accommodates up to the root portion of the joint pipe 118 when mounted. The water discharge head 106 is preferably in contact with the outer surface of the rotating unit 104, but at least close to the outer surface of the rotating unit 104 so that the joint between the rotating unit 104 and the water discharging head 106 is not noticeable.

（留具）
吐水ヘッド１０６の下部には周方向に延伸する差込口１２２が設けられる。吐水ヘッド１０６の収容部１０に突出管部２０を挿入した後、ユーザは差込口１２２から留具１２０を挿入する。留具１２０は、クリップ形状を有し、例えば所定の強度と弾力性を有する樹脂等から形成される。水栓本体部１１２に吐水ヘッド１０６を装着するとき、吐水ヘッド１０６の収容部１０に突出管部２０を収容して、吐水ヘッド１０６を回転部１０４に向けて押し込む。次に、差込口１２２から留具１２０を手で押し込む。留具１２０が継手管１１８をクリップのように把持（挟持）することで、吐水ヘッド１０６は回転部１０４に固定される。留具１２０を外せば、吐水ヘッド１０６を軸方向に引っ張ることにより、吐水ヘッド１０６を水栓本体部１１２から外すことができる。 (Fastener)
An insertion port 122 extending in the circumferential direction is provided below the water discharge head 106. After inserting the protruding tube portion 20 into the housing portion 10 of the water discharge head 106, the user inserts the fastener 120 from the insertion port 122. The fastener 120 has a clip shape, and is formed of, for example, a resin having a predetermined strength and elasticity. When the water discharge head 106 is attached to the faucet main body 112, the protruding pipe portion 20 is accommodated in the accommodating portion 10 of the water discharge head 106, and the water discharge head 106 is pushed toward the rotating portion 104. Next, the fastener 120 is pushed in from the insertion port 122 by hand. The water discharge head 106 is fixed to the rotating unit 104 by the fastener 120 gripping (clamping) the joint pipe 118 like a clip. If the fastener 120 is removed, the water discharge head 106 can be removed from the faucet body 112 by pulling the water discharge head 106 in the axial direction.

なお、本実施形態における「着脱可能」は、接着や溶接などにより、吐水ヘッド１０６と水栓本体部１１２を完全固定する構造は含まない。家庭で一般ユーザが自ら着脱できる構造であり、スクリュードライバーなどの着脱のための専用工具を必須としない構造が好ましい。そこで、本実施形態の水栓１００では、吐水ヘッド１０６と水栓本体部１１２を留具１２０により固定している。留具１２０は工具を使わなくても、指や爪でも挿抜できる。なお、留具１２０は任意の金属棒等をひっかけて取り外すようにしてもよい。留具１２０を用いることは必須の構成ではない。   The “detachable” in the present embodiment does not include a structure that completely fixes the water discharge head 106 and the faucet main body 112 by bonding or welding. A structure in which a general user can attach and detach himself / herself at home, and a structure that does not require a dedicated tool for attaching and detaching such as a screwdriver is preferable. Therefore, in the faucet 100 of the present embodiment, the water discharge head 106 and the faucet main body 112 are fixed by the fastener 120. The fastener 120 can be inserted and removed with a finger or a nail without using a tool. The fastener 120 may be removed by hooking an arbitrary metal rod or the like. The use of the fastener 120 is not an essential configuration.

吐水ヘッド１０６に回転力を加えて操作することで回転部１０４を回転させることがある。このとき、継手管１１８の根元部分には回転にともなう応力が集中する。このため、継手管１１８と回転部１０４の接続強度を向上することが望ましい。そこで、本実施形態の水栓１００では、継手管１１８の根元部分に継手管１１８の中央部の外径よりも大きな外径を有する外径拡大部１７４が設けられている。外径拡大部１７４は、例えばテーパー形状を有する。   The rotating unit 104 may be rotated by operating the water discharge head 106 by applying a rotational force. At this time, the stress accompanying the rotation is concentrated on the root portion of the joint pipe 118. For this reason, it is desirable to improve the connection strength between the joint pipe 118 and the rotating portion 104. Therefore, in the faucet 100 of the present embodiment, an outer diameter enlarged portion 174 having an outer diameter larger than the outer diameter of the central portion of the joint pipe 118 is provided at the root portion of the joint pipe 118. The outer diameter enlarged portion 174 has a tapered shape, for example.

吐水ヘッド１０６は、外径拡大部１７４の全部または一部を収容するように回転部１０４に向けて押し込まれて装着される。吐水ヘッド１０６は、その端部を回転部１０４の外側面と当接させ、外径拡大部１７４を完全に収容してもよい。   The water discharge head 106 is pushed in and attached to the rotating portion 104 so as to accommodate all or part of the outer diameter enlarged portion 174. The water discharge head 106 may have its end abutted against the outer surface of the rotating portion 104 to completely accommodate the outer diameter enlarged portion 174.

（吐水ヘッド）
図３は、吐水ヘッド１０６の分解斜視図である。吐水ヘッド１０６は、外殻１２６、内管１２８、吐水口部材１３０および整流部材１３２を含む。 (Water discharge head)
FIG. 3 is an exploded perspective view of the water discharge head 106. The water discharge head 106 includes an outer shell 126, an inner pipe 128, a water discharge port member 130, and a flow regulating member 132.

（内管）
内管１２８は、略軸方向に延伸する管状の部材で、上流側の端部に収容部１０が設けられる。収容部１０は筒状部材１７２と継手管１１８を含む突出管部２０を収容する。内管１２８は内部に水の通り道である通水部１８４（図１も参照）を有しており、水道水は、通水管１１０から筒状部材１７２と内管１２８の通水部１８４を経由して、吐水口部材１３０に至り、整流部材１３２を通ってシンク（図示せず）に吐水される。通水管１１０には弁（図示せず）が接続される。弁は、支柱部１０８に内蔵されており、吐水ハンドル１０２および操作突起１１６によって開閉される。 (Inner pipe)
The inner tube 128 is a tubular member extending substantially in the axial direction, and the accommodating portion 10 is provided at the upstream end. The accommodating part 10 accommodates the protruding pipe part 20 including the cylindrical member 172 and the joint pipe 118. The inner pipe 128 has a water passage portion 184 (see also FIG. 1) that is a passage for water inside. The tap water passes from the water passage pipe 110 through the tubular member 172 and the water passage portion 184 of the inner pipe 128. Then, the water reaches the spout member 130 and is discharged through the flow regulating member 132 to the sink (not shown). A valve (not shown) is connected to the water conduit 110. The valve is built in the support column 108 and is opened and closed by the water discharge handle 102 and the operation projection 116.

外殻１２６は、吐水ヘッド１０６の筐体であり、内管１２８の外側を覆う管状の部材である。つまり、吐水ヘッド１０６は、内管１２８と外殻１２６の二重構造を有する。吐水ヘッド１０６は二重構造を有することにより、吐水ヘッド１０６全体の強度を向上させている。回転部１０４は支柱部１０８を回転軸として回動自在に支持される。回転部１０４から分岐する突出管部２０に吐水ヘッド１０６が接続される。回転部１０４が回転することによって、吐水ヘッド１０６は回転部１０４と共に回転する。また、吐水ヘッド１０６と共に接続継手８２と筒状部材１７２も一体的に回転する。   The outer shell 126 is a casing of the water discharge head 106 and is a tubular member that covers the outside of the inner tube 128. That is, the water discharge head 106 has a double structure of the inner tube 128 and the outer shell 126. The water discharge head 106 has a double structure, thereby improving the strength of the water discharge head 106 as a whole. The rotating unit 104 is supported so as to be rotatable about the column unit 108 as a rotation axis. The water discharge head 106 is connected to the protruding tube portion 20 branched from the rotating portion 104. As the rotating unit 104 rotates, the water discharge head 106 rotates together with the rotating unit 104. In addition, the connection joint 82 and the cylindrical member 172 rotate together with the water discharge head 106.

吐水ヘッド１０６は突出管部２０の延長上に設けられているから、吐水ヘッド１０６を水平方向に回転することで、その回転力がそのまま突出管部２０の継手管１１８に伝達される。このため、ユーザによる回転操作を回転部１０４の回転力として伝えることができる。突出管部２０は、吐水ヘッド１０６の装着時には外観を構成しない。   Since the water discharge head 106 is provided on the extension of the protruding pipe portion 20, the rotational force is transmitted to the joint pipe 118 of the protruding pipe portion 20 as it is by rotating the water discharge head 106 in the horizontal direction. For this reason, the rotation operation by the user can be transmitted as the rotational force of the rotating unit 104. The protruding tube portion 20 does not form an appearance when the water discharge head 106 is mounted.

内管１２８は、外殻１２６のほぼ全域をカバーするように、吐水口部材１３０から外殻１２６の回転部１０４と対向する端部まで延伸されてもよい。特に、内管１２８の端部と外殻１２６の端部はほぼ一致している。内管１２８は、水栓本体部１１２に装着されるとき、外径拡大部１７４の全部または一部を収容するように押し込まれる。内管１２８は、外殻１２６の端部から内管１２８の一部が飛び出す形状であってもよい。   The inner tube 128 may be extended from the water outlet member 130 to the end of the outer shell 126 facing the rotating portion 104 so as to cover almost the entire area of the outer shell 126. In particular, the end of the inner tube 128 and the end of the outer shell 126 are substantially coincident. When the inner pipe 128 is attached to the faucet body 112, the inner pipe 128 is pushed to accommodate all or part of the outer diameter enlarged portion 174. The inner tube 128 may have a shape in which a part of the inner tube 128 protrudes from the end of the outer shell 126.

外殻１２６は外観を構成するから美観が重視される。内管１２８は外殻１２６に覆われるから、外観を構成する機会は少なく、美観はそれほど重要ではない。内管１２８は水の通り道であり、継手管１１８に直接接合されるため、特にその内部構造には高い加工精度が求められる。   Since the outer shell 126 constitutes the appearance, aesthetics are emphasized. Since the inner tube 128 is covered by the outer shell 126, there are few opportunities for constructing the appearance, and the aesthetics are not so important. Since the inner pipe 128 is a passage for water and is directly joined to the joint pipe 118, a high machining accuracy is particularly required for its internal structure.

外殻１２６および内管１２８は、例えばＡＢＳ樹脂やポリアセタール等の樹脂材料からモールド成型工程により形成することができる。この場合、外殻１２６および内管１２８の軽量化およびコストダウンに有利である。外殻１２６を軽量化することで、交換用の吐水ヘッド１０６を容易に持ち運びすることができる。外殻１２６は、樹脂メッキ加工が施され、外表面に金属光沢を有するメッキ面が設けられる。   The outer shell 126 and the inner tube 128 can be formed from a resin material such as ABS resin or polyacetal by a molding process. In this case, the outer shell 126 and the inner tube 128 are advantageous in terms of weight reduction and cost reduction. By reducing the weight of the outer shell 126, the replacement water discharge head 106 can be easily carried. The outer shell 126 is subjected to a resin plating process, and a plated surface having a metallic luster is provided on the outer surface.

樹脂部品にメッキを施す工程では、樹脂部品を高温のメッキ液に浸すため、樹脂部品は高温のストレスにより変形して加工精度が低下することがある。そこで、実施形態における吐水ヘッド１０６では、内管１２８を外殻１２６で覆う二重構造とすることで、美観が重視される外殻１２６にはメッキ面を形成し、加工精度が重視される内管１２８はメッキ面を有しない構成としている。特に、内管１２８は、第１収容部１８６および第２収容部１８８を含む全体の表面が、非メッキ面から構成されている。   In the process of plating the resin component, the resin component is immersed in a high-temperature plating solution, so that the resin component may be deformed by high-temperature stress and the processing accuracy may be lowered. Therefore, in the water discharge head 106 according to the embodiment, by forming a double structure in which the inner tube 128 is covered with the outer shell 126, a plating surface is formed on the outer shell 126 where aesthetics are important, and the processing accuracy is important. The tube 128 is configured not to have a plated surface. In particular, the entire surface of the inner tube 128 including the first housing portion 186 and the second housing portion 188 is formed of a non-plated surface.

回転部１０４の外側面は円筒形状である曲面形状を有する。外殻１２６の端面および内管１２８の端面は、回転部１０４の外側面の曲面形状と一致する形状を有する。特に、外殻１２６の端面および内管１２８の端面は外径拡大部１７４のテーパー面に一致する形状を有する。このように構成することにより、吐水ヘッド１０６と回転部１０４を隙間無く接続できる。   The outer surface of the rotating unit 104 has a curved surface shape that is a cylindrical shape. The end surface of the outer shell 126 and the end surface of the inner tube 128 have shapes that match the curved surface shape of the outer surface of the rotating unit 104. In particular, the end surface of the outer shell 126 and the end surface of the inner tube 128 have a shape that matches the tapered surface of the outer diameter enlarged portion 174. By comprising in this way, the water discharging head 106 and the rotation part 104 can be connected without gap.

（着脱機構）
次に、水栓１００の着脱機構について説明する。本実施形態においては、回転部１０４から突出する突出管部２０を吐水ヘッド１０６の収容部１０に収容することで吐水ヘッド１０６を水栓本体部１１２に接続している。収容部１０は後述する第１収容部１８６と第２収容部１８８とを含む。吐水ヘッド１０６と回転部１０４の接合部分である境界部は、突出管部２０の継手管１１８の根元に形成される。水栓１００では、本体側面から突出する突出管部２０の継手管１１８および筒状部材１７２を吐水ヘッド１０６が覆う。このため、吐水ヘッド１０６の外殻１２６は、その内径や外径を比較的自由に設計することができる。 (Removal mechanism)
Next, the attachment / detachment mechanism of the faucet 100 will be described. In the present embodiment, the water discharge head 106 is connected to the faucet main body 112 by accommodating the protruding tube portion 20 protruding from the rotating portion 104 in the accommodating portion 10 of the water discharge head 106. The accommodating part 10 includes a first accommodating part 186 and a second accommodating part 188 described later. A boundary portion that is a joint portion between the water discharge head 106 and the rotating portion 104 is formed at the base of the joint pipe 118 of the protruding pipe portion 20. In the faucet 100, the water discharge head 106 covers the joint pipe 118 and the cylindrical member 172 of the protruding pipe portion 20 protruding from the side surface of the main body. For this reason, the outer shell 126 of the water discharge head 106 can be designed relatively freely in its inner diameter and outer diameter.

図１に示すように、吐水ヘッド１０６が回転部１０４の外側面から突出する突出管部２０を収容する構成では、回転部１０４の表面が境界部となるから、境界面が吐水ヘッドの軸方向の途中にある場合に比べて接合部分が目につきにくい。吐水ヘッド１０６は、図１に示すように、内管１２８が突出管部２０を収容しつつ回転部１０４に直接的に接続される。外殻１２６は内管１２８の接続部分をカバーして直接的には接続部分に関与しない。このため、外殻１２６は、接続によるストレスを受けにくいから、外殻１２６の形状や材質などの設計自由度を高くすることができる。   As shown in FIG. 1, in the configuration in which the water discharge head 106 accommodates the protruding tube portion 20 that protrudes from the outer surface of the rotation unit 104, the boundary surface is the axial direction of the water discharge head because the surface of the rotation unit 104 is a boundary portion. Compared with the case where it is in the middle, the joint portion is less noticeable. As shown in FIG. 1, the water discharge head 106 is directly connected to the rotating part 104 while the inner pipe 128 accommodates the protruding pipe part 20. The outer shell 126 covers the connecting portion of the inner tube 128 and does not directly participate in the connecting portion. For this reason, since the outer shell 126 is not easily subjected to stress due to connection, the degree of freedom in designing the shape and material of the outer shell 126 can be increased.

図４は水栓１００の突出管部２０の周辺の側面図である。図４はＯリング１５２が装着されていない状態を示している。図４に示すように、突出管部２０は継手管１１８と筒状部材１７２を含む。筒状部材１７２は、継手管１１８の先端より小さい外径を有し、継手管１１８の内側に差し込まれている。筒状部材１７２は後述する接続機構９０によって継手管１１８に接続されている。筒状部材１７２の上側（下流側）の一端１７２ａは、継手管１１８から軸方向に突き出しており、継手管１１８から露出している。筒状部材１７２の下側（上流側）の他端１７２ｂは、回転部１０４中の通水口１２４に挿入され、接続継手８２に接続される（図１も参照）。継手管１１８の回転部１０４との接続部分には外径拡大部１７４が形成される。外径拡大部１７４は、回転部１０４に近づくほど外径が大きくなるテーパー形状を有する。継手管１１８は回転部１０４と一体に樹脂材料からモールド成形により形成される。継手管１１８と回転部１０４を型枠から外す際には、継手管１１８に対応する部分を押出すようにしてもよい。この場合、外部に露出する回転部１０４への傷付きを減らすことができる。   FIG. 4 is a side view of the periphery of the protruding tube portion 20 of the water tap 100. FIG. 4 shows a state where the O-ring 152 is not attached. As shown in FIG. 4, the protruding pipe portion 20 includes a joint pipe 118 and a cylindrical member 172. The tubular member 172 has an outer diameter smaller than the tip of the joint pipe 118 and is inserted inside the joint pipe 118. The cylindrical member 172 is connected to the joint pipe 118 by a connection mechanism 90 described later. One end 172 a on the upper side (downstream side) of the cylindrical member 172 protrudes in the axial direction from the joint pipe 118 and is exposed from the joint pipe 118. The other end 172b on the lower side (upstream side) of the tubular member 172 is inserted into the water passage 124 in the rotating unit 104 and connected to the connection joint 82 (see also FIG. 1). An outer diameter enlarged portion 174 is formed at a connection portion of the joint pipe 118 with the rotating portion 104. The outer diameter enlarged portion 174 has a tapered shape in which the outer diameter increases as the rotating portion 104 is approached. The joint pipe 118 is formed by molding from a resin material integrally with the rotating portion 104. When the joint pipe 118 and the rotating part 104 are removed from the mold, a portion corresponding to the joint pipe 118 may be extruded. In this case, damage to the rotating unit 104 exposed to the outside can be reduced.

図１に示すように、吐水ヘッド１０６の外殻１２６の端面および内管１２８の端面は、外径拡大部１７４に対向する。外殻１２６および内管１２８にはテーパー状の端面である吐水ヘッドの端面１８０が設けられる（図８も参照）。吐水ヘッドの端面１８０のテーパー面は、外径拡大部１７４の外側面のテーパー面と、略平行な角度で対向する。吐水ヘッド１０６の端面１８０のテーパー面を外径拡大部１７４のテーパー面と同一の曲面形状にすることによって、境界部の隙間を目立ちにくくすることができる。吐水ヘッド１０６は、吐水ヘッドの端面１８０の少なくとも一部が回転部１０４に当接状態または非当接状態にて、回転部１０４と対向してもよい。   As shown in FIG. 1, the end surface of the outer shell 126 and the end surface of the inner tube 128 of the water discharge head 106 face the outer diameter enlarged portion 174. The outer shell 126 and the inner tube 128 are provided with an end surface 180 of the water discharge head, which is a tapered end surface (see also FIG. 8). The tapered surface of the end surface 180 of the water discharge head faces the tapered surface of the outer surface of the outer diameter enlarged portion 174 at a substantially parallel angle. By making the taper surface of the end surface 180 of the water discharge head 106 the same curved surface shape as the taper surface of the outer diameter enlarged portion 174, the gap at the boundary portion can be made inconspicuous. The water discharge head 106 may face the rotation unit 104 when at least a part of the end surface 180 of the water discharge head is in contact with or not in contact with the rotation unit 104.

（収容部）
図１に示すように、内管１２８の内側面には、通水部１８４と、第１収容部１８６と、第２収容部１８８とが設けられる。通水部１８４は第１収容部１８６の下流側に設けられる水の通り道である。第１収容部１８６は、第２収容部１８８の下流側に設けられ、主に筒状部材１７２を収容する。第２収容部１８８は、第１収容部１８６の上流側に設けられ、主に継手管１１８を収容する。第２収容部１８８の上流側の端面１８０は吐水ヘッドの端面１８０を構成する。第１収容部１８６は通水部１８４より大きな内径を有し、第２収容部１８８は第１収容部１８６より大きな内径を有する。収容部１０が小径の第１収容部１８６と大径の第２収容部１８８の二段構造になるから、第１収容部１８６と筒状部材１７２の間にてシールを形成して水漏れを抑制し、第２収容部１８８と継手管１１８の間にて半径方向のガタを抑制することができる。 (Container)
As shown in FIG. 1, a water passage portion 184, a first housing portion 186, and a second housing portion 188 are provided on the inner surface of the inner tube 128. The water passage portion 184 is a water passage provided on the downstream side of the first housing portion 186. The first accommodating portion 186 is provided on the downstream side of the second accommodating portion 188 and mainly accommodates the tubular member 172. The second accommodating portion 188 is provided on the upstream side of the first accommodating portion 186 and mainly accommodates the joint pipe 118. An end surface 180 on the upstream side of the second housing portion 188 constitutes an end surface 180 of the water discharge head. The first accommodating portion 186 has an inner diameter larger than that of the water passage portion 184, and the second accommodating portion 188 has an inner diameter larger than that of the first accommodating portion 186. Since the accommodating portion 10 has a two-stage structure including a first accommodating portion 186 having a small diameter and a second accommodating portion 188 having a large diameter, a seal is formed between the first accommodating portion 186 and the tubular member 172 to prevent water leakage. It is possible to suppress the play in the radial direction between the second housing portion 188 and the joint pipe 118.

図１に示すように、筒状部材１７２は、継手管１１８より小さな外径を有し、その外周面にはＯリング１５２が取り付けられる。Ｏリング１５２は、弾性を有するゴムなどの材料から形成される。Ｏリング１５２は、筒状部材１７２と第１収容部１８６の間のシールとして水の漏れ出しを抑制する。   As shown in FIG. 1, the cylindrical member 172 has an outer diameter smaller than that of the joint pipe 118, and an O-ring 152 is attached to the outer peripheral surface thereof. The O-ring 152 is formed from a material such as rubber having elasticity. The O-ring 152 suppresses leakage of water as a seal between the cylindrical member 172 and the first storage portion 186.

継手管１１８の根元に外径拡大部１７４を形成しているから、継手管１１８と回転部１０４の接合が強化される。吐水ヘッドの端面１８０の曲面形状を外径拡大部１７４の曲面形状と同一の曲面形状としているから、境界部が目立ちにくい。なお、ここでいう「同一の曲面形状」とは、吐水ヘッド１０６と外径拡大部１７４の対向部分に大きな隙間、たとえば、１．０ミリメートル以上の隙間が生じない程度に吐水ヘッドの端面１８０の形状を外径拡大部１７４の曲面形状に近づけることをいう。   Since the outer diameter enlarged portion 174 is formed at the root of the joint pipe 118, the joint between the joint pipe 118 and the rotating portion 104 is strengthened. Since the curved surface shape of the end surface 180 of the water discharge head is the same curved surface shape as the curved surface shape of the outer diameter enlarged portion 174, the boundary portion is hardly noticeable. The “same curved surface shape” as used herein refers to the end surface 180 of the water discharge head to such an extent that a large gap, for example, a gap of 1.0 mm or more does not occur in the opposite portion of the water discharge head 106 and the outer diameter enlarged portion 174. This refers to bringing the shape closer to the curved surface shape of the outer diameter enlarged portion 174.

（接続機構）
次に、継手管１１８に筒状部材１７２を接続する接続機構９０について説明する。筒状部材１７２は、継手管１１８および接続継手８２に対して簡易に接続されることが施工上望ましいが、水栓本体部１１２から吐水ヘッド１０６を外した際に、意図せず、筒状部材１７２が継手管１１８から外れることは防ぐ必要がある。そこで、実施の形態の水栓１００では、筒状部材１７２を継手管１１８に対して筒状部材１７２の周方向に回転させることによって、筒状部材１７２が継手管１１８に接続されるように構成される接続機構９０を備えている。このような接続機構９０を有することにより、継手管１１８から筒状部材１７２を外すときも逆方向に回転させることになるから、意図せず、筒状部材１７２が継手管１１８から外れる可能性を小さくすることができる。 (Connection mechanism)
Next, the connection mechanism 90 that connects the tubular member 172 to the joint pipe 118 will be described. Although it is desirable in terms of construction that the tubular member 172 is simply connected to the joint pipe 118 and the connection joint 82, when the water discharge head 106 is removed from the faucet body 112, the tubular member 172 is not intended. It is necessary to prevent 172 from coming off the joint pipe 118. Therefore, the faucet 100 according to the embodiment is configured such that the tubular member 172 is connected to the joint pipe 118 by rotating the tubular member 172 with respect to the joint pipe 118 in the circumferential direction of the tubular member 172. The connecting mechanism 90 is provided. By having such a connection mechanism 90, when the cylindrical member 172 is removed from the joint pipe 118, the cylindrical member 172 is rotated in the reverse direction. Can be small.

筒状部材１７２の上流側の他端１７２ｂを通水口１２４に密着させるために、筒状部材１７２は、継手管１１８に対して軸方向に押し込むように装着されることが望ましい。そこで、実施の形態の水栓１００では、接続機構９０は、筒状部材１７２を継手管１１８に対して筒状部材１７２の周方向に回転させることによって、筒状部材１７２が継手管１１８の軸方向に変位するように構成されている。筒状部材１７２を回転させることによって、筒状部材１７２が軸方向で継手管１１８の上流側に向かって変位するから、他端１７２ｂは通水口１２４に押しつけられ、これらの密着性を向上することができる。   In order to bring the other end 172 b on the upstream side of the tubular member 172 into close contact with the water outlet 124, the tubular member 172 is preferably mounted so as to be pushed into the joint pipe 118 in the axial direction. Therefore, in the faucet 100 of the embodiment, the connection mechanism 90 rotates the tubular member 172 with respect to the joint pipe 118 in the circumferential direction of the tubular member 172, so that the tubular member 172 is connected to the shaft of the joint pipe 118. It is configured to be displaced in the direction. By rotating the cylindrical member 172, the cylindrical member 172 is displaced toward the upstream side of the joint pipe 118 in the axial direction, and therefore, the other end 172b is pressed against the water passage 124, thereby improving the adhesion thereof. Can do.

また逆に、他端１７２ｂが通水口１２４に長期間密着していた場合に、他端１７２ｂが通水口１２４に貼り付いて容易に外れないことがある。特に、本実施形態のように接続部分にＯリング１５５を有する水栓では、長期間の使用によりＯリング１５５が周囲の部材に貼り付いていることがある。この場合には、Ｏリング１５５を周囲の部材から剥がしながら筒状部材１７２を継手管１１８から軸方向に引き抜くことになり、過度に力が必要となる場合が有る。本実施形態では筒状部材１７２を継手管１１８に対して接続時と逆方向に回転させることによって、筒状部材１７２が継手管１１８から下流側に向かって軸方向に変位するから、他端１７２ｂは通水口１２４から剥がれて容易に取り外すことができる。   Conversely, when the other end 172b is in close contact with the water passage 124 for a long period of time, the other end 172b may stick to the water passage 124 and cannot be easily removed. In particular, in a faucet having an O-ring 155 at the connection portion as in the present embodiment, the O-ring 155 may be attached to surrounding members after long-term use. In this case, the cylindrical member 172 is pulled out from the joint pipe 118 in the axial direction while peeling the O-ring 155 from the surrounding members, and an excessive force may be required. In the present embodiment, the cylindrical member 172 is rotated in the direction opposite to that at the time of connection to the joint pipe 118, whereby the cylindrical member 172 is displaced in the axial direction from the joint pipe 118 toward the downstream side, so that the other end 172b. Can be easily removed by peeling from the water passage 124.

次に、実施の形態の水栓１００の接続機構９０について詳しく説明する。図５は継手管１１８の周辺を説明する説明図である。図５において、円Ｆは継手管１１８の周辺を上から視た図であり、円Ｇは継手管１１８を軸方向から視た図である。図６は筒状部材１７２の側面図である。図６において、図６（ａ）は筒状部材１７２の係合凸部１９２が上下の両側に位置する姿勢における側面から視た図で、図６（ｂ）は筒状部材１７２の係合凸部１９２をその突出方向から視た図である。図６において矢印Ｔは軸方向で下流側を示す。   Next, the connection mechanism 90 of the faucet 100 of the embodiment will be described in detail. FIG. 5 is an explanatory view for explaining the periphery of the joint pipe 118. In FIG. 5, a circle F is a view of the periphery of the joint pipe 118 as viewed from above, and a circle G is a view of the joint pipe 118 as viewed from the axial direction. FIG. 6 is a side view of the cylindrical member 172. 6A is a view as seen from the side in a posture in which the engaging convex portions 192 of the cylindrical member 172 are positioned on both the upper and lower sides, and FIG. 6B is an engaging convex portion of the cylindrical member 172. It is the figure which looked at the part 192 from the protrusion direction. In FIG. 6, an arrow T indicates the downstream side in the axial direction.

接続機構９０としては構成がシンプルで生産が容易であることが望ましい。そこで、実施の形態の水栓１００では、継手管１１８の内面と筒状部材１７２の外面の一方には係合溝部が設けられ、継手管１１８の内面と筒状部材１７２の外面の他方には係合溝部に係合する係合凸部が設けられている。水栓１００では、図５に示すように、継手管１１８の内面に係合溝部１９０が設けられている。係合溝部１９０は、それぞれ円周方向に延在する溝部１９０ａと溝部１９０ｂとを含む。溝部１９０ａと溝部１９０ｂは周方向に略１８０度離れて対面する位置に設けられる。係合溝部１９０の溝部１９０ａと溝部１９０ｂは、継手管１１８の内面から外面に向かって貫通している。継手管１１８には、継手管１１８の端面から軸方向に沿って延在して係合溝部１９０につながる導入溝１９１が設けられている。導入溝１９１は、溝部１９０ａにつながる導入溝１９１ａと、溝部１９０ｂにつながる導入溝１９１ｂとを含む。導入溝１９１は継手管１１８の内面から外面に向かって貫通しておらず、凹状である。係合溝部１９０についても、継手管１１８の内面から外面に向かって貫通しない凹状に形成してもよい。   It is desirable that the connection mechanism 90 has a simple configuration and is easy to produce. Therefore, in the faucet 100 of the embodiment, an engagement groove is provided on one of the inner surface of the joint pipe 118 and the outer surface of the tubular member 172, and the other of the inner surface of the joint pipe 118 and the outer surface of the tubular member 172 is provided. An engagement convex portion that engages with the engagement groove is provided. In the faucet 100, as shown in FIG. 5, an engagement groove 190 is provided on the inner surface of the joint pipe 118. Each of the engaging groove portions 190 includes a groove portion 190a and a groove portion 190b extending in the circumferential direction. The groove portion 190a and the groove portion 190b are provided at positions facing each other at a distance of about 180 degrees in the circumferential direction. The groove portion 190a and the groove portion 190b of the engagement groove portion 190 penetrate from the inner surface of the joint pipe 118 toward the outer surface. The joint pipe 118 is provided with an introduction groove 191 that extends from the end surface of the joint pipe 118 along the axial direction and is connected to the engagement groove portion 190. The introduction groove 191 includes an introduction groove 191a connected to the groove part 190a and an introduction groove 191b connected to the groove part 190b. The introduction groove 191 does not penetrate from the inner surface of the joint pipe 118 toward the outer surface, and is concave. The engaging groove 190 may also be formed in a concave shape that does not penetrate from the inner surface of the joint pipe 118 toward the outer surface.

筒状部材１７２の外面には、図６に示すように、係合溝部１９０に係合する係合凸部１９２が設けられている。係合凸部１９２は、半径方向外側に突出する突起状の部分で、それぞれ溝部１９０ａと溝部１９０ｂに係合する、周方向に略１８０度離れて対面する位置に設けられた凸部１９２ａと凸部１９２ｂとを含む。凸部１９２ａと凸部１９２ｂとは突出方向に垂直な断面が円形状、オーバル形状、矩形状、多角形状などの形状に形成される。   On the outer surface of the cylindrical member 172, as shown in FIG. 6, an engaging convex portion 192 that engages with the engaging groove portion 190 is provided. The engaging convex portion 192 is a protruding portion that protrudes outward in the radial direction, and engages with the groove portion 190a and the groove portion 190b, respectively. The engaging convex portion 192 protrudes from the convex portion 192a provided at a position facing the circumferential direction approximately 180 degrees apart. Part 192b. The convex part 192a and the convex part 192b have a cross section perpendicular to the protruding direction, such as a circular shape, an oval shape, a rectangular shape, or a polygonal shape.

図７は筒状部材１７２が継手管１１８に係合する過程を説明する説明図である。図７は、周方向に延在する係合溝部１９０を縦方向に展開して示しており、係合溝部１９０内を係合凸部１９２が移動する過程を示している。図７において矢印Ｔは軸方向で下流側を示す。図７に示すように、係合溝部１９０は、導入溝１９１に繋がる入口部１９０ｍと、入口部１９０ｍから周方向に離れた内方部１９０ｎと、を有する。入口部１９０ｍと、内方部１９０ｎと、は軸方向にずれて段違いに形成されている。まず、係合凸部１９２は、図７にて１９２（１）で示すように、継手管１１８の端面から導入溝１９１に進入する。次に、係合凸部１９２は、図７にて１９２（２）で示すように、軸方向に沿って入口部１９０ｍに移動する。次に、筒状部材１７２が回転されることによって、係合凸部１９２は、図７にて１９２（３）で示すように、周方向に沿って内方部１９０ｎに移動する。このとき、内方部１９０ｎは入口部１９０ｍと段違いの奥側（水栓本体側）に形成されているから、係合凸部１９２が入口部１９０ｍから内方部１９０ｎに移動する過程で、筒状部材１７２が継手管１１８の軸方向の奥側に変位することになる。   FIG. 7 is an explanatory view illustrating a process in which the tubular member 172 engages with the joint pipe 118. FIG. 7 shows the engagement groove portion 190 extending in the circumferential direction in the longitudinal direction, and shows a process in which the engagement protrusion 192 moves in the engagement groove portion 190. In FIG. 7, the arrow T indicates the downstream side in the axial direction. As shown in FIG. 7, the engagement groove 190 includes an inlet portion 190m connected to the introduction groove 191 and an inward portion 190n separated from the inlet portion 190m in the circumferential direction. The inlet portion 190m and the inward portion 190n are formed to be stepped in the axial direction. First, as shown by 192 (1) in FIG. 7, the engaging convex part 192 enters the introduction groove 191 from the end face of the joint pipe 118. Next, as shown by 192 (2) in FIG. 7, the engaging convex portion 192 moves to the inlet portion 190m along the axial direction. Next, when the cylindrical member 172 is rotated, the engaging convex portion 192 moves to the inward portion 190n along the circumferential direction as indicated by 192 (3) in FIG. At this time, since the inner portion 190n is formed on the far side (faucet body side) that is different from the inlet portion 190m, the engagement convex portion 192 moves in the process of moving from the inlet portion 190m to the inner portion 190n. The shaped member 172 is displaced to the back side in the axial direction of the joint pipe 118.

接続機構９０は、一例として、筒状部材１７２が継手管１１８に対して反時計回りに回転するとき、筒状部材１７２は継手管１１８から抜ける方向に変位し、時計回りに回転するとき、筒状部材１７２は継手管１１８に押し込まれる方向に変位するように構成されてもよい。このように、接続機構９０は、筒状部材１７２を継手管１１８に対して回転させることによって、筒状部材１７２が継手管１１８に接続されるように構成されており、筒状部材１７２を継手管１１８に対して回転させることによって、筒状部材１７２が継手管１１８の軸方向に変位するように構成されている。   As an example, the connection mechanism 90 is configured such that when the cylindrical member 172 rotates counterclockwise with respect to the joint pipe 118, the cylindrical member 172 is displaced in a direction to come out of the joint pipe 118 and rotates clockwise. The shaped member 172 may be configured to be displaced in a direction to be pushed into the joint pipe 118. Thus, the connection mechanism 90 is configured such that the cylindrical member 172 is connected to the joint pipe 118 by rotating the cylindrical member 172 with respect to the joint pipe 118, and the cylindrical member 172 is connected to the joint pipe 118. The tubular member 172 is configured to be displaced in the axial direction of the joint pipe 118 by being rotated with respect to the pipe 118.

（具体的構造）
次に、水栓１００の具体的な構造について説明する。図８は実施形態に係る水栓１００の吐水ヘッド１０６の断面図である。図１の水栓本体部１１２に接続されている吐水ヘッド１０６である。以下、水栓本体部１１２に浄水機能を持たない吐水ヘッド１０６を装着した水栓を水栓１００ａと表記することがある。図８に示すように、吐水ヘッド１０６の内管１２８は、吐水口部材１３０に接続される。内管１２８と吐水口部材１３０の間にはＯリング１５４が挟まれている。吐水口部材１３０の出口は整流部材１３２によってキャップされる。整流部材１３２は、内管１２８からの流水を整流して泡沫水に変える。 (Specific structure)
Next, a specific structure of the faucet 100 will be described. FIG. 8 is a cross-sectional view of the water discharge head 106 of the faucet 100 according to the embodiment. It is the water discharge head 106 connected to the faucet body 112 of FIG. Hereinafter, the faucet in which the water discharge head 106 having no water purification function is attached to the faucet body 112 may be referred to as a faucet 100a. As shown in FIG. 8, the inner tube 128 of the water discharge head 106 is connected to the water discharge member 130. An O-ring 154 is sandwiched between the inner tube 128 and the water outlet member 130. The outlet of the spout member 130 is capped by a rectifying member 132. The rectifying member 132 rectifies the flowing water from the inner pipe 128 and converts it into foam water.

図１に示すように、筒状部材１７２は継手管１１８に挿入され、筒状部材１７２の下側の他端１７２ｂは通水口１２４に接続される。筒状部材１７２の他端１７２ｂと通水口１２４の間はＯリング１５５により止水される。   As shown in FIG. 1, the tubular member 172 is inserted into the joint pipe 118, and the other end 172 b on the lower side of the tubular member 172 is connected to the water outlet 124. Water is stopped by an O-ring 155 between the other end 172 b of the cylindrical member 172 and the water passage 124.

吐水ヘッド１０６は、内管１２８に継手管１１８が挿入された状態で、留具１２０が継手管１１８を把持することで、継手管１１８に固定される。特に、留具１２０は、外殻１２６の差込口１２２ａから差し込まれ、内管１２８の差込口１２２ｂを通じて継手管１１８を把持する。   The water discharge head 106 is fixed to the joint pipe 118 when the fastener 120 holds the joint pipe 118 in a state where the joint pipe 118 is inserted into the inner pipe 128. In particular, the fastener 120 is inserted from the insertion port 122 a of the outer shell 126 and grips the joint pipe 118 through the insertion port 122 b of the inner tube 128.

（浄水機能）
次に、浄水機能を有する吐水ヘッド１４８について説明する。図９は浄水機能を有する吐水ヘッド１４８の断面図であり、図１０は吐水ヘッド１４８を水栓本体部１１２に装着した水栓１００ｂの断面図である。水栓１００ｂは、水栓１００ａの水栓本体部１１２から浄水機能を持たない吐水ヘッド１０６を取り外し、浄水機能を有する吐水ヘッド１４８に交換することで得られる。 (Water purification function)
Next, a water discharge head 148 having a water purification function will be described. FIG. 9 is a cross-sectional view of a water discharge head 148 having a water purification function, and FIG. 10 is a cross-sectional view of a water tap 100b in which the water discharge head 148 is attached to the water tap main body 112. The faucet 100b is obtained by removing the water discharge head 106 having no water purification function from the water faucet main body 112 of the water faucet 100a and replacing it with a water discharge head 148 having a water purification function.

吐水ヘッド１４８は、内管１７０、外殻１６４、吐水部材１６０、浄水ハンドル１６２、Ｏリング１６６、弁１６８、カートリッジ保持部１５６および浄水カートリッジ１５８を含む。内管１７０は外周を外殻１６４によってカバーされる。吐水ヘッド１４８は、内管１７０と外殻１６４の二重構造を有する。内管１７０には継手管１１８と筒状部材１７２からなる突出管部２０が収容される。吐水部材１６０は内管１７０の下流側の先端に取り付けられる。浄水ハンドル１６２は、原水と浄水を切り替えるための操作部材であり、外殻１６４の下流側に寄った側面に設けられる。   The water discharge head 148 includes an inner pipe 170, an outer shell 164, a water discharge member 160, a water purification handle 162, an O-ring 166, a valve 168, a cartridge holding unit 156, and a water purification cartridge 158. The outer circumference of the inner tube 170 is covered by the outer shell 164. The water discharge head 148 has a double structure of an inner tube 170 and an outer shell 164. The inner pipe 170 accommodates the protruding pipe portion 20 including the joint pipe 118 and the cylindrical member 172. The water discharge member 160 is attached to the downstream end of the inner tube 170. The purified water handle 162 is an operation member for switching between raw water and purified water, and is provided on a side surface of the outer shell 164 that is closer to the downstream side.

カートリッジ保持部１５６は、内管１７０と嵌合し、内管１７０の一部として設けられる。Ｏリング１６６は内管１７０とカートリッジ保持部１５６の間に挿入される。浄水カートリッジ１５８はカートリッジ保持部１５６に内蔵される。浄水カートリッジ１５８は吐水部材１６０を取外すことで交換できる。   The cartridge holding portion 156 is fitted with the inner tube 170 and is provided as a part of the inner tube 170. The O-ring 166 is inserted between the inner tube 170 and the cartridge holding part 156. The water purification cartridge 158 is built in the cartridge holding unit 156. The water purification cartridge 158 can be replaced by removing the water discharge member 160.

弁１６８はカートリッジ保持部１５６の内部に設けられる。弁１６８は、カートリッジ保持部１５６にセットされた浄水カートリッジ１５８によって押し出され、内管１７０とカートリッジ保持部１５６とを連通する。弁１６８は、浄水カートリッジ１５８が取り外されると、内管１７０内の水圧によって閉じられる。つまり、弁１６８は、通水状態で浄水カートリッジ１５８を取り外した時に、内管１７０の中の水をそのまま吐水ヘッド１４８の先端から噴射させないための安全装置である。   The valve 168 is provided inside the cartridge holding unit 156. The valve 168 is pushed out by the water purification cartridge 158 set in the cartridge holding unit 156 and communicates the inner tube 170 and the cartridge holding unit 156. The valve 168 is closed by the water pressure in the inner pipe 170 when the water purification cartridge 158 is removed. That is, the valve 168 is a safety device that prevents the water in the inner pipe 170 from being sprayed from the tip of the water discharge head 148 as it is when the water purification cartridge 158 is removed in a water flow state.

ユーザの作業空間を確保する観点から、吐水ヘッド１０６とシンクの間の空間である吐水空間は広い方が好ましい。そこで、実施の形態の水栓１００では、図１に示すように、吐水ヘッド１０６の上面が水栓本体部１１２となす角度θは鋭角にされている。このように構成することによって、角度θが鈍角である場合に比べて、吐水ヘッド１０６の下流側が上方に位置するから、シンクからの距離が長くなり、吐水空間を広くすることができる。   From the viewpoint of securing the work space for the user, it is preferable that the water discharge space, which is the space between the water discharge head 106 and the sink, is wide. Therefore, in the faucet 100 of the embodiment, as shown in FIG. 1, the angle θ between the upper surface of the water discharge head 106 and the faucet body 112 is an acute angle. By configuring in this way, compared to the case where the angle θ is an obtuse angle, since the downstream side of the water discharge head 106 is positioned upward, the distance from the sink is increased and the water discharge space can be widened.

次に、このように構成された水栓１００の特徴を説明する。
水栓１００は、通水部材８４と、通水部材８４を覆うハウジング８６を有する水栓本体部１１２と、水栓本体部１１２に着脱可能に装着される吐水ヘッド１０６と、を備える。筒状部材１７２は、通水部材８４と吐水ヘッド１０６とを連通させ、水栓本体部１１２から突出して設けられる。このため、水栓本体部１１２から吐水ヘッド１０６を外したときにも、筒状部材１７２の上流側の他端１７２ｂは水栓本体部１１２内部の通水部材８３に接続したままであるため、筒状部材の無い水栓と比較して、水栓本体部１１２内部での漏水のおそれを小さくすることができる。 Next, features of the faucet 100 configured in this way will be described.
The faucet 100 includes a water passage member 84, a faucet body portion 112 having a housing 86 that covers the water passage member 84, and a water discharge head 106 that is detachably attached to the faucet body portion 112. The tubular member 172 communicates with the water passage member 84 and the water discharge head 106 and is provided so as to protrude from the faucet main body 112. For this reason, even when the water discharge head 106 is removed from the faucet body 112, the other end 172b on the upstream side of the tubular member 172 remains connected to the water passage member 83 inside the faucet body 112. Compared with a faucet without a tubular member, the risk of water leakage inside the faucet body 112 can be reduced.

水栓１００は、突出管部２０が、継手管１１８と、継手管１１８に挿入される筒状部材１７２と、を含み、吐水ヘッド１０６は、突出管部２０を収容する収容部１０を有する。このため、収容部１０が、継手管１１８と、継手管１１８に挿入される筒状部材１７２と、を含む二重構造の突出管部２０を収容することで、筒状部材が安定しがたつきにくくなり、接続強度が向上する。   The faucet 100 includes a protruding pipe portion 20 including a joint pipe 118 and a cylindrical member 172 inserted into the joint pipe 118, and the water discharge head 106 includes a housing portion 10 that houses the protruding pipe portion 20. For this reason, since the accommodating part 10 accommodates the protruding pipe part 20 of the double structure containing the joint pipe 118 and the cylindrical member 172 inserted in the joint pipe 118, the cylindrical member is not stabilized. It becomes difficult to stick and connection strength improves.

水栓１００は、筒状部材１７２を水栓本体部１１２に対して回転させることによって、筒状部材１７２が水栓本体部１１２に接続されるように構成される接続機構を備える。このため、筒状部材を軸方向に沿って水栓本体部１１２に押し込むことで接続する構成の水栓と比較して、比較的小さな力で楽に筒状部材１７２を水栓本体部１１２に接続することができる。また、筒状部材を軸方向に沿って押し込むと、力の掛け具合によっては部材を変形させる懸念がある。水栓１００では、回転させることで接続されるから、部材を変形させる懸念を小さくすることができる。   The faucet 100 includes a connection mechanism configured to connect the tubular member 172 to the faucet body 112 by rotating the tubular member 172 relative to the faucet body 112. For this reason, the cylindrical member 172 is easily connected to the faucet body 112 with a relatively small force as compared with the faucet configured to push the tubular member into the faucet body 112 along the axial direction. can do. Further, when the cylindrical member is pushed in along the axial direction, there is a concern that the member may be deformed depending on how much force is applied. In the faucet 100, since it is connected by rotating, the concern which deform | transforms a member can be made small.

水栓１００は、筒状部材１７２を継手管１１８に対して回転させることによって、筒状部材１７２が継手管１１８に接続されるように構成される接続機構９０を備える。このため、比較的小さな力で楽に筒状部材１７２を継手管１１８に接続することができる。また、筒状部材１７２が意図せず継手管１１８から外れる可能性を小さくすることができる。   The faucet 100 includes a connection mechanism 90 configured to connect the tubular member 172 to the joint pipe 118 by rotating the tubular member 172 with respect to the joint pipe 118. For this reason, the cylindrical member 172 can be easily connected to the joint pipe 118 with a relatively small force. Further, the possibility that the tubular member 172 is unintentionally detached from the joint pipe 118 can be reduced.

水栓１００は、接続機構９０が、筒状部材１７２を継手管１１８に対して回転させることによって、筒状部材１７２が継手管１１８の軸方向に変位するように構成されるから、筒状部材１７２を装着するときは、筒状部材１７２の回転により継手管１１８の上流側に向かって変位するように構成し、筒状部材１７２を取り外すときは、筒状部材１７２の逆回転により継手管１１８の下流側に向かって変位するように構成することができる。このように構成することによって、小さな力で筒状部材１７２を継手管１１８に対して着脱することが可能になる。   The faucet 100 is configured so that the tubular member 172 is displaced in the axial direction of the joint pipe 118 when the connection mechanism 90 rotates the tubular member 172 with respect to the joint pipe 118. When the cylindrical member 172 is mounted, it is configured to be displaced toward the upstream side of the joint pipe 118 by the rotation of the cylindrical member 172. When the cylindrical member 172 is removed, the joint pipe 118 is rotated by the reverse rotation of the cylindrical member 172. It can comprise so that it may displace toward the downstream of this. With this configuration, the cylindrical member 172 can be attached to and detached from the joint pipe 118 with a small force.

水栓１００は、接続機構９０が、継手管１１８の内面に設けられる係合溝部１９０と、筒状部材１７２の外面に設けられ、係合溝部１９０に係合する係合凸部１９２と、を含んでいる。このように構成された係合溝部１９０や係合凸部１９２は、比較的簡単な構造の金型によって容易に樹脂成型できるから、生産性や金型費用の観点で有利である。   The faucet 100 includes an engagement groove portion 190 provided on the inner surface of the joint pipe 118 and an engagement convex portion 192 provided on the outer surface of the tubular member 172 and engaged with the engagement groove portion 190. Contains. Since the engaging groove 190 and the engaging convex portion 192 configured in this way can be easily resin-molded by a mold having a relatively simple structure, it is advantageous in terms of productivity and mold cost.

以上、本発明の実施の形態をもとに説明した。これらの実施の形態は例示であり、いろいろな変形および変更が本発明の特許請求範囲内で可能なこと、またそうした変形例および変更も本発明の特許請求の範囲にあることは当業者に理解されるところである。従って、本明細書での記述および図面は限定的ではなく例証的に扱われるべきものである。   In the above, it demonstrated based on embodiment of this invention. Those skilled in the art will understand that these embodiments are examples, and that various modifications and changes are possible within the scope of the claims of the present invention, and that such modifications and changes are also within the scope of the claims of the present invention. It is where it is done. Accordingly, the description and drawings herein are to be regarded as illustrative rather than restrictive.

（変形例）
次に、変形例に係る水栓２００について説明する。図１１は水栓２００の接続機構９３を説明する側面図である。図１１（ａ）は図４に対応する突出管部２２０の周辺の側面図、図１１（ｂ）は継手管２１８を断面で示した側面図である。水栓２００は水栓１００に対して接続機構９０を削除し接続機構９３を加えた点で異なり、他の構成は同様であるから重複する説明を省く。水栓２００は継手管１１８の代わりに継手管２１８を、筒状部材１７２の代わりに筒状部材２７２を含む。接続機構９３は、図１１（ｂ）に示すように、継手管２１８の内面に設けられる雌ねじ部９２と、筒状部材２７２の外面に設けられ雌ねじ部９２に螺合する雄ねじ部９４と、を含む。雌ねじ部９２は螺旋状の傾斜を有するから、雄ねじ部９４が雌ねじ部９２にねじ込まれることで、回転力が軸方向の推力に変換され、筒状部材２７２は軸方向に沿って変位する。雌ねじ部９２は継手管２１８の先端側に設けてあるため、見えやすく作業性が良い。 (Modification)
Next, a faucet 200 according to a modification will be described. FIG. 11 is a side view for explaining the connection mechanism 93 of the faucet 200. FIG. 11A is a side view of the periphery of the protruding pipe portion 220 corresponding to FIG. 4, and FIG. 11B is a side view showing the joint pipe 218 in cross section. The faucet 200 is different from the faucet 100 in that the connection mechanism 90 is deleted and a connection mechanism 93 is added, and the other configurations are the same, and thus redundant description is omitted. The faucet 200 includes a joint pipe 218 instead of the joint pipe 118 and a cylindrical member 272 instead of the cylindrical member 172. As shown in FIG. 11B, the connection mechanism 93 includes a female screw portion 92 provided on the inner surface of the joint pipe 218 and a male screw portion 94 provided on the outer surface of the cylindrical member 272 and screwed into the female screw portion 92. Including. Since the female screw portion 92 has a spiral inclination, the male screw portion 94 is screwed into the female screw portion 92, whereby the rotational force is converted into axial thrust, and the cylindrical member 272 is displaced along the axial direction. Since the female thread portion 92 is provided on the distal end side of the joint pipe 218, it is easy to see and has good workability.

接続機構９３は、一例として、筒状部材２７２が継手管２１８に対して反時計回りに回転するとき、筒状部材２７２は継手管２１８から抜ける方向に変位し、時計回りに回転するとき、筒状部材２７２は継手管２１８に押し込まれる方向に変位するように構成されている。このように構成することにより、小さな力で筒状部材２７２を継手管２１８から外すことが可能になり、小さな力で筒状部材２７２を継手管２１８に装着することができる。   As an example, the connection mechanism 93 is configured such that when the cylindrical member 272 rotates counterclockwise with respect to the joint pipe 218, the cylindrical member 272 is displaced in a direction to come out of the joint pipe 218 and rotates clockwise. The shaped member 272 is configured to be displaced in a direction to be pushed into the joint pipe 218. With this configuration, the cylindrical member 272 can be detached from the joint pipe 218 with a small force, and the cylindrical member 272 can be attached to the joint pipe 218 with a small force.

変形例の水栓２００は、実施形態の水栓１００と同様の構成を有することで、前述した水栓１００の特徴を有する。また、変形例の水栓２００は、継手管２１８が筒状部材２７２と全周で均等に接するから、筒状部材２７２に対する継手管２１８の同軸性を確保し易い。   The variation faucet 200 has the same configuration as the faucet 100 of the embodiment, and thus has the characteristics of the faucet 100 described above. Moreover, since the joint pipe 218 contacts the cylindrical member 272 uniformly in the entire periphery, the water faucet 200 according to the modified example can easily ensure the coaxiality of the joint pipe 218 with respect to the cylindrical member 272.

実施の形態の水栓１００の説明では、筒状部材１７２が、水栓本体部１１２の回転部１０４から突出する継手管１１８に挿入される例について説明したが、これに限られない。例えば、水栓本体部から突出する継手管は設けずに、筒状部材が水栓本体部から外側に突出する構成であってもよい。   In the description of the faucet 100 of the embodiment, the example in which the tubular member 172 is inserted into the joint pipe 118 protruding from the rotating portion 104 of the faucet main body 112 has been described, but the present invention is not limited thereto. For example, the structure which a cylindrical member protrudes outside from a faucet main-body part may be sufficient, without providing the coupling pipe | tube which protrudes from a faucet main-body part.

For example, the cylindrical member may be connected to the faucet body using a pin or the like which is a separate member.

実施の形態の水栓１００の説明では、係合溝部１９０が溝部１９０ａと溝部１９０ｂの二つの溝部を含む例について説明したが、これに限られない。係合溝部１９０は、一つまたは３以上の溝部を含むようにしてもよい。   In the description of the faucet 100 of the embodiment, the example in which the engagement groove portion 190 includes the two groove portions of the groove portion 190a and the groove portion 190b has been described, but the present invention is not limited thereto. The engagement groove portion 190 may include one or three or more groove portions.

実施の形態の水栓１００の説明では、継手管１１８の内面に係合溝部１９０が設けられ、筒状部材１７２の外面に係合凸部１９２が設けられる例について説明したが、これに限られない。係合溝部が筒状部材に設けられ、係合凸部が継手管に設けられてもよい。   In the description of the faucet 100 according to the embodiment, the example in which the engagement groove portion 190 is provided on the inner surface of the joint pipe 118 and the engagement convex portion 192 is provided on the outer surface of the cylindrical member 172 has been described. Absent. The engagement groove portion may be provided in the tubular member, and the engagement convex portion may be provided in the joint pipe.

説明に使用した図面では、部材の関係を明瞭にするために一部の部材の断面にハッチングを施しているが、当該ハッチングはこれらの部材の素材や材質を制限するものではない。   In the drawings used for the description, in order to clarify the relationship between members, the cross sections of some members are hatched. However, the hatching does not limit the materials and materials of these members.
