Description

本発明は、吐水管から給水ホースを引き出し可能な吐水装置に関する。   The present invention relates to a water discharger capable of pulling a water supply hose from a water discharge pipe.

従来より、センサを用いて、吐水の有無を自動的に切り替え可能な自動水栓が広く知られている。この自動水栓としてはホース引き出し式のものが提案されている。この自動水栓では、一般に、キッチンシンク等に吐水管が支持され、吐水管の先端開口部から給水ホースが引き出し可能に設けられる。給水ホースには吐水ヘッドが接続され、吐水ヘッドは、吐水管の先端開口部に固定されるヘッド装着部材に着脱可能に保持される(特許文献1参照)。   2. Description of the Related Art Conventionally, automatic faucets that can automatically switch the presence or absence of water discharge using a sensor are widely known. A hose pull-out type has been proposed as this automatic faucet. In this automatic water faucet, a water discharge pipe is generally supported by a kitchen sink or the like, and a water supply hose is provided so as to be able to be pulled out from a front end opening of the water discharge pipe. A water discharge head is connected to the water supply hose, and the water discharge head is detachably held by a head mounting member that is fixed to the tip opening of the water discharge pipe (see Patent Document 1).

この種の自動水栓は、通常、吐水管にヘッド装着部材を固定するための固定具を、ヘッド装着部材にインサート成形により埋め込んで一体化している。固定具にはビス等の締結具をねじ込むための雌ねじ孔が形成される。ヘッド装着部材は、吐水管と固定具を締結具により締結することによって吐水管に固定される。   In this type of automatic water faucet, a fixing tool for fixing the head mounting member to the water discharge pipe is normally embedded in the head mounting member by insert molding. A female screw hole for screwing a fastener such as a screw is formed in the fixture. The head mounting member is fixed to the water discharge pipe by fastening the water discharge pipe and the fixture with a fastener.

特許第5247392号公報Japanese Patent No. 5247392

ところで、吐水管の内周面とヘッド装着部材の間には、製造誤差等に起因して隙間が生じることがある。従来の構造では、これらの間に隙間があると、固定具に対する締結具の締め付け量を大きくしたときに、固定具がヘッド装着部材とともに締結具の軸方向に引っ張られてしまう。よって、締結具の締め付け量によって吐水管の径方向でのヘッド装着部材の相対位置が変化してしまい、吐水管に対してヘッド装着部材を定位置に配置し難くなっている。吐水管に対するヘッド装着部材の位置ずれが大きくなると、ヘッド装着部材に保持される吐水ヘッドの位置ずれも大きくなり、吐水ヘッドの外周面と吐水管の外周面との間で大きな段差が生じることで意匠性の低下を招きかねない。   By the way, a gap may be generated between the inner peripheral surface of the water discharge pipe and the head mounting member due to a manufacturing error or the like. In the conventional structure, if there is a gap between them, when the fastening amount of the fastener with respect to the fixture is increased, the fixture is pulled together with the head mounting member in the axial direction of the fastener. Therefore, the relative position of the head mounting member in the radial direction of the water discharge pipe changes depending on the tightening amount of the fastener, and it is difficult to place the head mounting member at a fixed position with respect to the water discharge pipe. When the positional displacement of the head mounting member with respect to the water discharge pipe increases, the positional displacement of the water discharge head held by the head mounting member also increases, resulting in a large step between the outer peripheral surface of the water discharge head and the outer peripheral surface of the water discharge pipe. It may cause a decrease in design.

本発明は、このような課題に鑑みてなされ、その目的は、締結具の締め付け量によらず吐水管に対してヘッド装着部材を定位置に配置し易くできる吐水装置を提供することにある。   This invention is made | formed in view of such a subject, The objective is to provide the water discharging apparatus which can arrange | position a head mounting member in a fixed position with respect to a water discharging pipe easily irrespective of the fastening amount of a fastener.

上記課題を解決するために、本発明のある態様の吐水装置は、先端側に開口部が設けられる吐水管と、開口部から引き出し可能な給水ホースと、給水ホースが接続され、給水ホースから供給される水を吐き出し可能な吐水ヘッドと、吐水ヘッドを着脱可能に保持する保持部と、吐水管の内周面と対向する位置に形成される収容部とを有するヘッド装着部材と、収容部内に収容される固定具と、を備え、ヘッド装着部材は、吐水管と固定具を締結具により締結することによって、吐水管に対する位置が保持され、固定具は収容部に対して吐水管の径方向に相対変位可能に設けられる。
この態様によれば、固定具に対する締結具の締め付け量が大きくなった場合でも、ヘッド装着部材の収容部内にて固定具が吐水管の径方向に変位する。この結果、締結具の軸方向にヘッド装着部材が引っ張られるのを防止でき、締結具の締め付け量によらず吐水管に対してヘッド装着部材を定位置に配置し易くなる。
In order to solve the above-described problem, a water discharge device according to an aspect of the present invention is connected to a water discharge pipe provided with an opening on the tip side, a water supply hose that can be pulled out from the opening, and a water supply hose, and is supplied from the water supply hose A head mounting member having a water discharge head capable of discharging the water to be discharged, a holding portion for detachably holding the water discharge head, and a storage portion formed at a position facing the inner peripheral surface of the water discharge pipe; The head mounting member is held in position with respect to the water discharge pipe by fastening the water discharge pipe and the fixing tool with the fastener, and the fixing tool is in the radial direction of the water discharge pipe with respect to the storage portion. It is provided so that relative displacement is possible.
According to this aspect, even when the tightening amount of the fastener with respect to the fixture is increased, the fixture is displaced in the radial direction of the water discharge pipe within the accommodating portion of the head mounting member. As a result, the head mounting member can be prevented from being pulled in the axial direction of the fastener, and the head mounting member can be easily placed at a fixed position with respect to the water discharge pipe regardless of the tightening amount of the fastener.

前述の態様において、収容部の内壁面と固定具との間に介装される弾性部材を備えてもよい。
この態様によれば、吐水管及び固定具に対してヘッド装着部材が相対変位しようとしたとき、その相対変位量が増大するほど弾性部材の弾性変形量が大きくなる。この結果、ヘッド装着部材の変位方向とは反対方向に弾性部材からヘッド装着部材に付与される弾性復元力が大きくなることで、ヘッド装着部材の相対変位が効果的に抑えられ、吐水管に対するヘッド装着部材のがたつきを抑えられる。
In the above-mentioned aspect, you may provide the elastic member interposed between the inner wall face of a accommodating part, and a fixing tool.
According to this aspect, when the head mounting member is about to be displaced relative to the water discharge pipe and the fixture, the elastic deformation amount of the elastic member increases as the relative displacement amount increases. As a result, the elastic restoring force applied from the elastic member to the head mounting member in the direction opposite to the displacement direction of the head mounting member is increased, so that the relative displacement of the head mounting member is effectively suppressed, and the head with respect to the water discharge pipe Shaking of the mounting member can be suppressed.

前述の態様において、ヘッド装着部材は、弾性部材により吐水管の管軸方向に付与される弾性復元力によって、吐水管の一部に押し当てられた状態で保持されてもよい。
この態様によれば、吐水管の管軸方向でのヘッド装着部材のがたつきを許容する隙間をなくした状態にできるうえ、弾性部材の弾性復元力によりヘッド装着部材が吐水管の一部から離れにくくなるため、吐水管に対するヘッド装着部材のがたつきを更に抑えられる。
In the above-described aspect, the head mounting member may be held in a state of being pressed against a part of the water discharge pipe by an elastic restoring force applied in the tube axis direction of the water discharge pipe by the elastic member.
According to this aspect, the gap for allowing the head mounting member to rattle in the tube axis direction of the water discharge pipe can be eliminated, and the head mounting member can be removed from a part of the water discharge pipe by the elastic restoring force of the elastic member. Since it becomes difficult to separate, rattling of the head mounting member with respect to the water discharge pipe can be further suppressed.

前述の態様において、吐水管内に配置される電装部材を更に備え、ヘッド装着部材は、吐水管内にて電装部材を支持することにより、吐水管内での電装部材の位置を保持する支持部を有してもよい。
この態様によれば、前述のように締結具の締め付け量によらず吐水管に対してヘッド装着部材を定位置に配置し易くなるため、ヘッド装着部材の支持部により支持される電装部材も、締結具の締め付け量によらず定位置に配置し易くなる。
In the above-mentioned aspect, the head mounting member further includes an electrical member disposed in the water discharge pipe, and the head mounting member has a support portion that holds the position of the electrical component in the water discharge pipe by supporting the electrical component member in the water discharge pipe. May be.
According to this aspect, since the head mounting member can be easily placed at a fixed position with respect to the water discharge pipe regardless of the tightening amount of the fastener as described above, the electrical member supported by the support portion of the head mounting member is also It becomes easy to arrange at a fixed position regardless of the tightening amount of the fastener.

本発明によれば、締結具の締め付け量によらず吐水管に対してヘッド装着部材を定位置に配置し易くなる。   According to this invention, it becomes easy to arrange | position a head mounting member in a fixed position with respect to a water discharge pipe irrespective of the fastening amount of a fastener.

The head mounting member 28 has a housing portion 28k formed at a position facing the inner peripheral surface of the water discharge pipe 16 in the vicinity of the second opening 16g of the water discharge pipe 16. The accommodating portion 28k is formed at a position facing the bent inner portion of the bulging portion 16b of the water discharge pipe 16. The accommodating portion 28k is a through hole formed so as to be recessed in a direction away from the inner peripheral surface of the water discharge pipe 16.

図9は図8の方向Dから収容部28kを見た図である。収容部28kは、図8、図9に示すように、吐水管16の内周面側に設けられる入口部28kaと、入口部28kaより奥側に設けられる回転規制部28kbとを有する。入口部28kaと回転規制部28kbの間には入口部28ka側に臨む段差部が設けられる。入口部28kaは、収容部28kの中心軸の軸線方向に直交する断面形状が円形状に形成され、回転規制部28kbは四角形状に形成される。   FIG. 9 is a view of the accommodating portion 28k viewed from the direction D in FIG. As shown in FIGS. 8 and 9, the housing portion 28 k includes an inlet portion 28 ka provided on the inner peripheral surface side of the water discharge pipe 16 and a rotation restricting portion 28 kb provided on the inner side of the inlet portion 28 ka.

The inlet portion 28ka has a circular cross section orthogonal to the axial direction of the central axis of the housing portion 28k, and the rotation restricting portion 28kb is formed in a quadrangular shape.

吐水装置10は、図8に示すように、収容部28k内に収容される固定具42を備える。固定具42は金属製である。固定具42は、収容部28kに対して吐水管16の径方向に相対変位可能に設けられる。   As shown in FIG. 8, the water discharge device 10 includes a fixture 42 accommodated in the accommodating portion 28k. The fixture 42 is made of metal. The fixture 42 is provided so as to be relatively displaceable in the radial direction of the water discharge pipe 16 with respect to the accommodating portion 28k.

図10は固定具42の斜視図である。固定具42は、図8、図10に示すように、入口部28ka内に配置される頭部42aと、回転規制部28kb内に配置される被規制部42bとを備える。頭部42aは、収容部28kの中心軸の軸線方向に直交する断面形状が円形状に形成される。被規制部42bは、収容部28kの軸線方向に直交する断面形状が四角形状に形成される。   FIG. 10 is a perspective view of the fixture 42. As shown in FIGS. 8 and 10, the fixture 42 includes a head portion 42a disposed in the inlet portion 28ka and a regulated portion 42b disposed in the rotation regulating portion 28kb. The head portion 42a has a circular cross-sectional shape that is orthogonal to the axial direction of the central axis of the accommodating portion 28k. The regulated portion 42b has a quadrangular cross-sectional shape perpendicular to the axial direction of the accommodating portion 28k.

図11は固定具42から締結具44(後述する)を取り外した状態を示す図である。固定具42の頭部42aの端面部には孔部42dが形成される。孔部42dは吐水管16の内周面から離れる方向に窪むように形成される有底孔である。孔部42dには孔部42dの中心軸Lc1の軸線方向の中間部に雌ねじ部42daが形成される。雌ねじ部42daには、図8に示すように、ビス等の締結具44がねじ込まれる。   FIG. 11 is a view showing a state where a fastener 44 (described later) is removed from the fixture 42. A hole portion 42d is formed in the end surface portion of the head portion 42a of the fixture 42. The hole 42 d is a bottomed hole formed so as to be recessed in a direction away from the inner peripheral surface of the water discharge pipe 16. A female screw portion 42da is formed in the hole portion 42d at an intermediate portion in the axial direction of the central axis Lc1 of the hole portion 42d. As shown in FIG. 8, a fastener 44 such as a screw is screwed into the female screw portion 42da.

頭部42aの外周面には、図8、図10に示すように、孔部42dの中心軸Lc1の軸線方向での中間部に径方向内側に窪むような溝状の格納部42cが形成される。格納部42cにはOリング46が格納される。Oリング46は樹脂等の弾性をもつ素材により構成される弾性部材である。Oリング46はヘッド装着部材28の収容部28kの内壁面と固定具42との間に環状に介装される。Oリング46は、固定具42に対して吐水管16の管軸方向の先端側及び奥側の両側に位置するように配置されることになる。   As shown in FIGS. 8 and 10, a groove-shaped storage portion 42 c that is recessed inward in the radial direction is formed on the outer peripheral surface of the head portion 42 a at the intermediate portion in the axial direction of the central axis Lc 1 of the hole portion 42 d. The The O-ring 46 is stored in the storage unit 42c. The O-ring 46 is an elastic member made of a material having elasticity such as resin. The O-ring 46 is annularly interposed between the inner wall surface of the accommodating portion 28k of the head mounting member 28 and the fixture 42. The O-ring 46 is disposed so as to be located on both the distal end side and the back side in the tube axis direction of the water discharge pipe 16 with respect to the fixture 42.

吐水管16の膨出部16bには、ヘッド装着部材28の収容部28kや固定具42に対応する位置に挿通孔28jが形成される。挿通孔28jは吐水管16の外側から内側に向けて締結具44を挿通するためのものである。挿通孔28jは吐水管16の外側から内側に向かうにつれて縮径するようにテーパー状に形成される。   An insertion hole 28 j is formed in the bulging portion 16 b of the water discharge pipe 16 at a position corresponding to the housing portion 28 k and the fixture 42 of the head mounting member 28. The insertion hole 28j is for inserting the fastener 44 from the outside to the inside of the water discharge pipe 16. The insertion hole 28j is formed in a tapered shape so that the diameter decreases from the outer side of the water discharge pipe 16 toward the inner side.

締結具44はねじ山が形成される軸部44aと、軸部44aの一端側に設けられる頭部44bとを有する。頭部44bは吐水管16の外側から内側に向かうにつれて縮径するようにテーパー状に形成される。締結具44の頭部44bは、挿通孔28jの外側開口縁より内側に収まるように設けられる。   The fastener 44 has a shaft portion 44a where a screw thread is formed, and a head portion 44b provided on one end side of the shaft portion 44a. The head 44b is formed in a taper shape so that the diameter decreases as it goes from the outside to the inside of the water discharge pipe 16. The head 44b of the fastener 44 is provided so as to fit inside the outer opening edge of the insertion hole 28j.

以上の固定具42では、固定具42の雌ねじ部42daに締結具44をねじ込むとき、固定具42の被規制部42bとヘッド装着部材28の回転規制部28kbとの係合により、締結具44の軸方向周りでの固定具42の回転が規制され、締結具44を雌ねじ部42daにねじ込み可能となる。   In the fixing tool 42 described above, when the fastener 44 is screwed into the female thread portion 42da of the fixing tool 42, the engagement of the restricted portion 42b of the fixing device 42 and the rotation restricting portion 28kb of the head mounting member 28 results in the engagement of the fastener 44. The rotation of the fixing tool 42 around the axial direction is restricted, and the fastener 44 can be screwed into the female screw portion 42da.

ヘッド装着部材28は、吐水管16と固定具42を締結具44により締結することによって、吐水管16に対する位置が保持される。以下では、締結具44により締結される前後での固定具42等の状態を説明する。   The head mounting member 28 is held in a position relative to the water discharge pipe 16 by fastening the water discharge pipe 16 and the fixture 42 with the fastener 44. Below, the state of the fixing tool 42 etc. before and after being fastened by the fastening tool 44 will be described.

固定具42から締結具44を取り外したとき、Oリング46は、図11に示すように、ヘッド装着部材28の収容部28kと固定具42との間で弾性変形した状態で保持される。これにより、固定具42は、Oリング46の弾性復元力によりヘッド装着部材28の収容部28kに対して保持されるため、ヘッド装着部材28と一体に取り扱い可能になる。   When the fastener 44 is removed from the fixture 42, the O-ring 46 is held in an elastically deformed state between the accommodating portion 28k of the head mounting member 28 and the fixture 42 as shown in FIG. As a result, the fixture 42 is held against the accommodating portion 28k of the head mounting member 28 by the elastic restoring force of the O-ring 46, so that it can be handled integrally with the head mounting member 28.

ヘッド装着部材28は、吐水管16内に各開口部16d、16g、16iから奥側に押し込んで入れたとき、吐水管16の挿通孔28jの中心軸Lc2よりも、固定具42の孔部42dの中心軸Lc1が吐水管16の先端側にずれて位置するように設けられる。この状態にある固定具42の雌ねじ部42daには締結具44の軸部44aがねじ込まれる。このとき、締結具44の軸部44aを通る軸線は、図12に示すように、固定具42の中心軸Lc1と合致するような位置に配置される。   When the head mounting member 28 is pushed into the water discharge pipe 16 from the openings 16d, 16g, and 16i to the back side, the hole 42d of the fixture 42 is located more than the central axis Lc2 of the insertion hole 28j of the water discharge pipe 16. The central axis Lc1 of the water discharge pipe 16 is provided so as to be shifted from the distal end side. The shaft portion 44a of the fastener 44 is screwed into the female screw portion 42da of the fixture 42 in this state. At this time, the axis passing through the shaft portion 44a of the fastener 44 is disposed at a position that matches the central axis Lc1 of the fixture 42 as shown in FIG.

この状態で締結具44を締め付けると、締結具44の頭部44bが挿通孔28jの内壁面と当接する。このとき、締結具44の頭部44bと挿通孔28jはテーパー状に形成されるため、締結具44の締め付け量が増すほど、締結具44の軸部44aを通る軸線が挿通孔28jの中心軸Lc2に近づく方向Eに、締結具44が固定具42とともに変位する。この方向Eとは、吐水管16の管軸方向の奥側に向かう方向となる。   When the fastener 44 is tightened in this state, the head portion 44b of the fastener 44 comes into contact with the inner wall surface of the insertion hole 28j. At this time, since the head portion 44b of the fastener 44 and the insertion hole 28j are formed in a taper shape, the axis passing through the shaft portion 44a of the fastener 44 becomes the center axis of the insertion hole 28j as the fastening amount of the fastener 44 increases. The fastener 44 is displaced together with the fixture 42 in the direction E approaching Lc2. This direction E is a direction toward the far side in the tube axis direction of the water discharge pipe 16.

この結果、Oリング46は、図8に示すように、固定具42に対して管軸方向の奥側にある収容部28kの内壁面と固定具42との間で管軸方向に圧縮されるように弾性変形した状態で保持される。このOリング46の弾性変形量は、固定具42に対して管軸方向の先端側にある部分より、奥側にある部分の方が大きくなる。これにより、ヘッド装着部材28には、Oリング46により管軸方向の奥側に向かう方向F1に弾性復元力が付与される。言い換えると、Oリング46の一部は、吐水管16と固定具42を締結具44により締結することによって、管軸方向に圧縮されるように弾性変形し、ヘッド装着部材28にはOリング46により吐水管16の管軸方向に弾性復元力が付与される。   As a result, as shown in FIG. 8, the O-ring 46 is compressed in the tube axis direction between the inner wall surface of the housing portion 28 k on the back side in the tube axis direction with respect to the fixture 42 and the fixture 42. Is held in an elastically deformed state. The elastic deformation amount of the O-ring 46 is greater in the portion on the far side than the portion on the distal end side in the tube axis direction with respect to the fixture 42. As a result, an elastic restoring force is applied to the head mounting member 28 in the direction F1 toward the inner side in the tube axis direction by the O-ring 46. In other words, a part of the O-ring 46 is elastically deformed so as to be compressed in the tube axis direction by fastening the water discharge pipe 16 and the fixing tool 42 with the fastening tool 44, and the O-ring 46 is formed on the head mounting member 28. Thus, an elastic restoring force is applied in the tube axis direction of the water discharge tube 16.

ここで、図5に示すように、本管部16aの第1開口部16dの内側には先端面より奥側に変位規制部16jが設けられる。変位規制部16jは、吐水管16の先端側に臨むように本管部16a内に設けられる段差面である。   Here, as shown in FIG. 5, a displacement regulating portion 16j is provided on the inner side of the first opening portion 16d of the main pipe portion 16a on the back side from the front end surface. The displacement restricting portion 16j is a step surface provided in the main pipe portion 16a so as to face the distal end side of the water discharge pipe 16.

ヘッド装着部材28は、図13に示すように、前述のOリング46により管軸方向の奥側に向かう方向F1に付与される弾性復元力によって、この吐水管16の変位規制部16jに第1端面部28cの裏面を押し当てられた状態で、吐水管16に対する位置が保持される。   As shown in FIG. 13, the head mounting member 28 is first applied to the displacement restricting portion 16j of the water discharge pipe 16 by the elastic restoring force applied in the direction F1 toward the inner side in the tube axis direction by the O-ring 46 described above. The position with respect to the water discharge pipe 16 is maintained in a state where the back surface of the end surface portion 28c is pressed.

以上の吐水装置10による作用効果を説明する。
固定具42はヘッド装着部材28の収容部28kに対して吐水管16の径方向に相対変位可能に設けられる。よって、固定具42に対する締結具44の締め付け量が大きくなった場合でも、ヘッド装着部材28の収容部28k内にて固定具42が吐水管16の径方向に変位する。この結果、締結具44の軸方向にヘッド装着部材28が引っ張られるのを防止でき、締結具44の締め付け量によらず吐水管16に対してヘッド装着部材28を定位置に配置し易くなる。
The effect by the above water discharging apparatus 10 is demonstrated.
The fixing tool 42 is provided so as to be relatively displaceable in the radial direction of the water discharge pipe 16 with respect to the housing portion 28 k of the head mounting member 28. Therefore, even when the fastening amount of the fastener 44 with respect to the fixture 42 is increased, the fixture 42 is displaced in the radial direction of the water discharge pipe 16 in the accommodating portion 28k of the head mounting member 28. As a result, the head mounting member 28 can be prevented from being pulled in the axial direction of the fastener 44, and the head mounting member 28 can be easily placed at a fixed position with respect to the water discharge pipe 16 regardless of the tightening amount of the fastener 44.

吐水管16に対してヘッド装着部材28を定位置に配置し易くなるため、ヘッド装着部材28に保持される吐水ヘッド18も、締結具44の締め付け量によらず吐水管16に対して定位置に配置し易くなる。これにより、吐水ヘッド18の外周面と吐水管16の膨出部16bの外周面とが管軸方向に段差なく面一につながるようにし易くなり、良好な意匠性、清掃性を得やすくなる。   Since the head mounting member 28 is easily disposed at a fixed position with respect to the water discharge pipe 16, the water discharge head 18 held by the head mounting member 28 is also positioned at a fixed position with respect to the water discharge pipe 16 regardless of the tightening amount of the fastener 44. It becomes easy to arrange in. As a result, the outer peripheral surface of the water discharge head 18 and the outer peripheral surface of the bulging portion 16b of the water discharge pipe 16 are easily connected to each other without any step in the tube axis direction, and good design and cleaning properties are easily obtained.

また、吐水管16に対してヘッド装着部材28を定位置に配置し易くなるため、ヘッド装着部材28の支持部28bにより支持される第2センサ部材26も、締結具44の締め付け量によらず吐水管16に対して定位置に配置し易くなる。これにより、第2センサ部材26の露出面26dと、吐水管16の本管部16aの外周面とが段差なく面一につながるようにし易くなり、良好な意匠性、清掃性を得やすくなる。   Further, since the head mounting member 28 can be easily placed at a fixed position with respect to the water discharge pipe 16, the second sensor member 26 supported by the support portion 28 b of the head mounting member 28 is also independent of the tightening amount of the fastener 44. It becomes easy to arrange at a fixed position with respect to the water discharge pipe 16. Thereby, it becomes easy to connect the exposed surface 26d of the 2nd sensor member 26 and the outer peripheral surface of the main pipe part 16a of the water discharge pipe 16 without level | step difference, and it becomes easy to obtain favorable design property and cleaning property.

また、ヘッド装着部材28の収容部28kと固定具42との間にはOリング46が介装される。よって、吐水管16及び固定具42に対してヘッド装着部材28が相対変位しようとしたとき、その相対変位量が増大するほどOリング46の弾性変形量が大きくなる。この結果、ヘッド装着部材28の変位方向とは反対方向にOリング46からヘッド装着部材28に付与される弾性復元力が大きくなることで、ヘッド装着部材28の相対変位が効果的に抑えられ、吐水管16に対するヘッド装着部材28のがたつきを抑えられる。   Further, an O-ring 46 is interposed between the accommodating portion 28 k of the head mounting member 28 and the fixture 42. Therefore, when the head mounting member 28 is about to be displaced relative to the water discharge pipe 16 and the fixture 42, the elastic deformation amount of the O-ring 46 increases as the relative displacement amount increases. As a result, the elastic restoring force applied to the head mounting member 28 from the O-ring 46 in the direction opposite to the displacement direction of the head mounting member 28 is increased, so that the relative displacement of the head mounting member 28 is effectively suppressed, Shaking of the head mounting member 28 with respect to the water discharge pipe 16 can be suppressed.

特に、ヘッド装着部材28は、吐水管16内に配置するとき、吐水管16の各開口部16d、16g、16iから奥側に挿入されるため、吐水管16の管軸方向に変位し易くなる。この点、本実施形態によれば、Oリング46が固定具42に対して吐水管16の管軸方向の両側に配置されるため、吐水管16に対するヘッド装着部材28の管軸方向でのがたつきをOリング46により抑えられる点で大きな利点がある。   In particular, when the head mounting member 28 is disposed in the water discharge pipe 16, the head mounting member 28 is easily inserted in the tube axis direction of the water discharge pipe 16 because it is inserted from the openings 16 d, 16 g and 16 i of the water discharge pipe 16 to the back side. . In this regard, according to the present embodiment, the O-rings 46 are disposed on both sides of the water discharge pipe 16 in the pipe axis direction with respect to the fixture 42, so that the head mounting member 28 in the pipe axis direction with respect to the water discharge pipe 16 is arranged. There is a great advantage in that rattling can be suppressed by the O-ring 46.

また、ヘッド装着部材28は、Oリング46の弾性復元力により、吐水管16の変位規制部16jに押し当てられた状態で保持される。よって、吐水管16の管軸方向でのヘッド装着部材28のがたつきを許容する隙間をなくした状態にできるうえ、Oリング46の弾性復元力によりヘッド装着部材28が変位規制部16jから離れにくくなるため、吐水管16に対するヘッド装着部材28のがたつきを更に抑えられる。   Further, the head mounting member 28 is held in a state of being pressed against the displacement restricting portion 16 j of the water discharge pipe 16 by the elastic restoring force of the O-ring 46. Therefore, the gap allowing the rattling of the head mounting member 28 in the tube axis direction of the water discharge pipe 16 can be eliminated, and the head mounting member 28 is separated from the displacement restricting portion 16j by the elastic restoring force of the O-ring 46. Since it becomes difficult, rattling of the head mounting member 28 with respect to the water discharge pipe 16 can be further suppressed.

また、ヘッド装着部材28は保持部28gの他に支持部28bを有するため、以下の利点がある。従来の特許文献1の構造では、吐水ヘッドが保持されるヘッド装着部材と、センサ部材を支持するセンサホルダとが別体に構成されている。よって、吐水装置のメンテナンスのため、吐水管内からセンサ部材を取り出すうえでは、ヘッド装着部材を吐水管から取り出した後に、特別な工具を用いてセンサホルダを吐水管から取り出す必要があった。このため、余計な作業工数を要するうえ、吐水管の開口部から工具を差し込むような煩雑な作業を要していた。   Further, since the head mounting member 28 has the support portion 28b in addition to the holding portion 28g, the following advantages are obtained. In the structure of the conventional patent document 1, the head mounting member that holds the water discharge head and the sensor holder that supports the sensor member are configured separately. Therefore, in order to take out the sensor member from the water discharge pipe for maintenance of the water discharge apparatus, it is necessary to take out the sensor holder from the water discharge pipe using a special tool after taking out the head mounting member from the water discharge pipe. For this reason, an extra work man-hour is required, and a complicated work of inserting a tool from the opening of the water discharge pipe is required.

この点、本実施形態によれば、ヘッド装着部材28は保持部28gの他に支持部28bを一体に有する。よって、吐水管16内から第2センサ部材26を取り出すうえで、保持部28gを掴んで引っ張れば、ヘッド装着部材28全体を各開口部16d、16g、16iを通して吐水管16内から取り出せる。このため、第2センサ部材26を取り出すために要する作業工数を減らせるうえ、特別な工具が不要となるため、良好な作業性を得られる。   In this regard, according to the present embodiment, the head mounting member 28 integrally includes the support portion 28b in addition to the holding portion 28g.
