Description

この発明は吐水装置に関し、詳しくは角パイプ材を用いて吐水パイプを構成して成る吐水装置に関する。   The present invention relates to a water discharge device, and more particularly to a water discharge device formed by forming a water discharge pipe using a square pipe material.

従来、使用者から見て即ち吐水パイプに対する正面視において吐水口を左右方向に長く、前後方向に短い扁平な形状とし、吐水をあたかも滝の如く吐水する滝口吐水口となした吐水装置がバスタブに給水を行う水栓の吐水装置として知られている。
例えば下記特許文献１，特許文献２，特許文献３にこの種の滝口吐水口を有する吐水装置の一例が開示されている。 Conventionally, when viewed from the user, that is, when viewed from the front with respect to the water discharge pipe, the water discharge device has a flat shape that is long in the left-right direction and short in the front-rear direction, and the water discharge device is a waterfall discharge port that discharges water just like a waterfall. It is known as a faucet discharging device that supplies water.
For example, the following Patent Document 1, Patent Document 2, and Patent Document 3 disclose an example of a water discharge device having this type of waterfall outlet.

この種の滝口吐水口を有する吐水装置は、従来、吐水パイプが鋳物製とされており、そしてその鋳物製の吐水パイプの先端部に上記の扁平な形状の吐水口を有する吐水口部材を取り付けて吐水装置を構成していた。   Conventionally, a water discharge device having a waterfall outlet of this type has a water discharge pipe made of cast metal, and a water discharge member having the flat water discharge port is attached to the tip of the water discharge pipe made of casting. And configured a water discharge device.

しかしながらこのような鋳物製の吐水パイプを用いた吐水装置は必然的に肉厚も厚くなり、また見た目にも大きなものとなってしまい、スリムで外観的にすっきりとした吐水装置を構成することが難しいのに加えてコストも高く、また吐水口部材を取り付けるための切削加工などの後加工も必要となってしまう。   However, a water discharge device using such a casting water discharge pipe inevitably becomes thick and large in appearance, and it is possible to constitute a water discharge device that is slim and clean in appearance. In addition to being difficult, the cost is high, and post-processing such as cutting for attaching the water outlet member is also required.

そこで吐水パイプとして横断面の内周形状が左右方向に長い扁平形状のパイプ材を用いることが考えられる。但しこのようなパイプ材を用いる場合は、通常は内周形状が横長の矩形状の角パイプ材を用いることとなる。   Therefore, it is conceivable to use a flat pipe material having an inner peripheral shape of the transverse section that is long in the left-right direction as the water discharge pipe. However, when such a pipe material is used, normally, a rectangular pipe material having a horizontally long inner peripheral shape is used.

このような角パイプ材を用いて吐水パイプを構成すれば、見た目に小さくてスリムな外観形状の吐水装置を容易に構成でき、またコストも安価に抑えることができるとともに、鋳物製の吐水パイプに必要とされる後加工も不要化することができる。
但しこの場合、吐水パイプの先端部に挿入状態に取り付けられる吐水口部材と吐水パイプとの間のシール構造が問題となる。 By configuring the water discharge pipe using such a square pipe material, it is possible to easily configure a water discharge device having an appearance that is small and slim in appearance, and it is possible to reduce the cost at a low cost. Necessary post-processing can also be eliminated.
However, in this case, there is a problem with the seal structure between the water discharge port member and the water discharge pipe attached in the inserted state at the tip of the water discharge pipe.

吐水口部材と吐水パイプとの間のシール構造として、吐水口部材の外周面にＯリング（全周に亘って角部を有しないリング形状をなした弾性を有するシール部材）を装着して、そのＯリングを吐水口部材の外周面と吐水パイプの内周面とで径方向に弾性圧縮させ、シールするといったことが考えられるが、吐水パイプを角パイプ材を用いて構成した場合、通常は吐水口部材のＯリングの装着個所の外周形状（横断面形状）を楕円形状等の周方向に連続した曲面形状となしておいて、そこにＯリングを保持させ、これを吐水パイプの内周面に径方向に押し付けてシールすることとなるが、角パイプ材を用いて構成した吐水パイプでは、その内周形状が角部を有する形状であるため、Ｏリングをその角部において径方向に挟み込むことができず、必要なシールを実現できない。   As a seal structure between the spout member and the spout pipe, an O-ring (an elastic seal member having a ring shape having no corners over the entire circumference) is attached to the outer peripheral surface of the spout member, It is conceivable that the O-ring is elastically compressed and sealed in the radial direction between the outer peripheral surface of the water outlet member and the inner peripheral surface of the water discharge pipe, but when the water discharge pipe is configured using a square pipe material, The outer peripheral shape (cross-sectional shape) of the O-ring mounting portion of the water discharge port member is a curved surface shape that is continuous in the circumferential direction such as an elliptical shape, and the O-ring is held there, and this is the inner periphery of the water discharge pipe It will be pressed against the surface in the radial direction and sealed, but in the water discharge pipe constructed using a square pipe material, the inner peripheral shape is a shape having a corner, so the O-ring is radially in the corner I ca n’t pinch it, It can not be achieved the required seal.

尤も吐水口部材におけるＯリングの装着個所の外周形状を矩形状とするといったことも考えられなくはないが、この場合においてもＯリングを全周に亘って均等に弾性圧縮し、シール作用させるといったことは実際上難しい。   Of course, it is not conceivable that the outer peripheral shape of the mounting portion of the O-ring in the water discharge port member is rectangular, but in this case as well, the O-ring is elastically compressed uniformly over the entire periphery to cause a sealing action. That is difficult in practice.

シール構造としては、その他に、角パイプ材から成る吐水パイプに対して吐水口部材を押し込んで、吐水口部材と吐水パイプとでシール部材を管軸方向に挟み込んで弾性圧縮し、シール作用させることが考えられるが、その場合、吐水口部材を押し込み且つその押込状態に維持するために、吐水口部材の先端面からビス等をねじ込んで吐水口部材を吐水パイプに固定するといったことが必要となる。   In addition, as the sealing structure, the water outlet member is pushed into the water discharge pipe made of a square pipe material, and the seal member is sandwiched in the tube axis direction between the water discharge port member and the water discharge pipe to be elastically compressed and sealed. However, in that case, in order to push the water outlet member and maintain it in the pushed state, it is necessary to screw a screw or the like from the front end surface of the water outlet member to fix the water outlet member to the water outlet pipe. .

しかしながらこのようにビス等を用いてシール確保するようになした場合、吐水口部材の先端面にビスねじ込みのためのスペースが必要となり、特に吐水口を左右方向に幅広く確保することが必要な滝口吐水口を有する吐水装置にあっては、そのようなスペースを確保することが困難である。   However, when a seal is secured using a screw or the like in this way, a space for screw screwing is required on the tip surface of the water discharge port member, and in particular, a waterfall port that needs to ensure a wide water discharge port in the left-right direction. In a water discharge device having a water discharge port, it is difficult to ensure such a space.

滝口吐水口から見た目に美しい滝のような吐水を行うためには、滝口吐水口をできるだけ左右方向に幅広い形状としておくことが望ましいが、ビスねじ込みのためのスペースを吐水口部材の先端面に設けると、吐水口の左右方向の幅が必然的に小さくなってしまい、幅の広い美しい滝のような吐水を実現できなくなってしまう。   In order to perform waterfall-like water discharge that looks beautiful from the waterfall outlet, it is desirable to make the waterfall outlet wide as wide as possible in the left and right direction. However, a space for screw screwing is provided on the tip of the water outlet member. Then, the width in the left-right direction of the water outlet becomes inevitably small, and it becomes impossible to realize water discharge like a wide and beautiful waterfall.

以上滝口吐水口を有する吐水装置を代表例として説明したが、角パイプ材を用いて吐水パイプを構成し、且つ吐水口の形状を角パイプ材の内周形状とは異なった形状とするために、別体の吐水口部材を吐水パイプに取り付けてシール部材をそれら吐水口部材と吐水パイプとで管軸方向に弾性圧縮してシールする場合、吐水口が左右又は前後等に狭小化する問題を生じる点で、滝口吐水口以外の吐水口を有する吐水装置においても上記と同様の問題を生じる。   As described above, the water discharge device having the waterfall outlet has been described as a representative example, but the square pipe material is used to configure the water discharge pipe, and the shape of the water outlet is different from the inner peripheral shape of the square pipe material. When a separate spout member is attached to the spout pipe and the seal member is sealed by elastic compression in the tube axis direction with the spout member and the spout pipe, the problem is that the spout narrows to the left or right or front and rear. In the point which arises, also in the water discharging apparatus which has water outlets other than a waterfall outlet water outlet, the same problem as the above arises.

尚本発明に対する先行技術として、特許文献４には吐水パイプの先端部に吐水口部材を挿入状態に取り付けた点が開示されている。
しかしながら特許文献４に開示のものは、整流機構部（吐水口部材）に対して、吐水パイプ内部に挿入した通水可撓管を給水ホースとして接続した形態のもので、吐水口部材と吐水パイプとの間をシールする必要は生じず（従ってこの文献に記載のものではそのためのシール部材は備えていない）、この特許文献４に開示のものは本発明の課題を解決することのできないもので本発明とは別異のものである。 In addition, as a prior art with respect to the present invention, Patent Document 4 discloses that a water discharge port member is attached to the distal end portion of the water discharge pipe in an inserted state.
However, what is disclosed in Patent Document 4 is a form in which a water flow flexible tube inserted inside a water discharge pipe is connected as a water supply hose to a rectifying mechanism (water discharge port member). There is no need to seal between the two (thus, the one described in this document does not include a sealing member for that purpose), and the one disclosed in Patent Document 4 cannot solve the problem of the present invention. This is different from the present invention.

本発明に対する先行技術として、他に特許文献５に開示されたものがある。即ちこの特許文献５には、流出管（吐水パイプ）の先端部に整流部材（吐水口部材）を挿入状態に取り付けた点が開示されているが、この特許文献５に開示のものにおいても、吐水口部材と吐水パイプの先端部との間のシール構造については示されておらず、本発明とは別異のものである。   Another prior art to the present invention is disclosed in Patent Document 5. That is, this Patent Document 5 discloses a point in which a rectifying member (a water discharge port member) is attached in an inserted state at a distal end portion of an outflow pipe (a water discharge pipe). The seal structure between the water outlet member and the tip of the water discharge pipe is not shown, and is different from the present invention.

発明の作用・効果Effects and effects of the invention

以上のように本発明は、内周形状が角形状をなす角パイプ材を用いて構成した吐水パイプに対し、内周面に、吐水パイプの角部に対応した部分が曲面をなし且つ全周に亘り角部を形成することなく連続した面を成すシール面を兼ねた雌嵌合面を形成した取付部材を、吐水パイプの先端の開口から内部に挿入して、全周に亘りこれをシール状態で吐水パイプに固定した上、その取付部材に対し、外周面に上記雌嵌合面に対応した形状の雄嵌合面を有し且つその雄嵌合面にリング形状のシール部材を保持させた吐水口部材を、それら雄嵌合面と雌嵌合面とでシール部材を径方向に弾性圧縮させる状態に雄嵌合面において雌嵌合面に嵌合させ、その嵌合状態で吐水口部材を固定手段にて吐水パイプに対し抜止状態に固定するようになしたものである。   As described above, the present invention relates to a water discharge pipe configured using a square pipe material having an inner peripheral shape of a square shape, and a portion corresponding to the corner of the water discharge pipe has a curved surface on the inner peripheral surface. A fitting member that forms a female fitting surface that also serves as a sealing surface that forms a continuous surface without forming a corner is inserted into the inside from the opening at the tip of the water discharge pipe, and this is sealed over the entire circumference. In this state, the fixing member is fixed to the water discharge pipe, and the mounting member has a male fitting surface having a shape corresponding to the female fitting surface on the outer peripheral surface, and a ring-shaped seal member is held on the male fitting surface. The water outlet member is fitted to the female fitting surface in the male fitting surface so that the sealing member is elastically compressed in the radial direction between the male fitting surface and the female fitting surface, and the water outlet in the fitted state. The member is fixed to the water discharge pipe by a fixing means.

かかる本発明によれば、角パイプ材を用いて吐水パイプを構成しつつ、これに吐水口部材を取り付けることにより、吐水装置を安価に構成することができるとともに、吐水装置における吐水口を角パイプ材の内周形状とは異なった所望の吐水口形状となすことができ、またＯリング等のシール部材を径方向に弾性圧縮させることで、良好に吐水口部材と吐水パイプとの間を取付部材を介して水密シール状態とすることができる。   According to this invention, while forming a water discharge pipe using a square pipe material, by attaching a water discharge port member to this, a water discharge device can be constituted at low cost, and the water discharge port in the water discharge device is a square pipe. It can be made into a desired water outlet shape different from the inner peripheral shape of the material, and a seal member such as an O-ring is elastically compressed in the radial direction, so that a good space between the water outlet member and the water discharge pipe can be attached. A watertight seal can be achieved through the member.

また径方向に弾性圧縮してシール作用するリング状のシール部材を用いることができるため、吐水口部材と吐水パイプとでシール部材を管軸方向に弾性圧縮してシールする場合のように、シール部材を管軸方向に弾性圧縮し且つ圧縮状態を維持するためのねじ等を吐水口の先端面からねじ込まなくてもよく、即ちねじ等のねじ込みのためのスペースを吐水口の先端面に確保しなくてもよく、これにより吐水口の先端面に吐水口のためのスペースを十分に確保することが可能となって、容易に所望の吐水口形状を実現することが可能となる。   In addition, since a ring-shaped seal member can be used that is elastically compressed in the radial direction and seals, the seal member is sealed by elastically compressing the seal member in the tube axis direction between the water discharge port member and the water discharge pipe. It is not necessary to screw a screw or the like for elastically compressing the member in the tube axis direction and maintaining the compressed state from the front end surface of the water outlet, that is, a space for screwing the screw or the like is secured on the front end surface of the water outlet. There is no need, and this makes it possible to secure a sufficient space for the water discharge port on the front end surface of the water discharge port, so that a desired water discharge port shape can be easily realized.

ここで上記取付部材は、外周面に、吐水パイプの内周形状に対応した角形状の雄嵌合面を有するものとなし、その雄嵌合面において取付部材を吐水パイプの内周面に嵌合させ、それら雄嵌合面と吐水パイプの内周面との間を全周に亘りシールしておくことができる（請求項２）。   Here, the mounting member has an angular male fitting surface corresponding to the inner peripheral shape of the water discharge pipe on the outer peripheral surface, and the mounting member is fitted to the inner peripheral surface of the water discharge pipe on the male fitting surface. Thus, the space between the male fitting surface and the inner peripheral surface of the water discharge pipe can be sealed over the entire circumference (claim 2).

また吐水パイプと取付部材とは、それぞれを金属製となし、それらを全周溶接して互いをシール状態に接合しておくことができる（請求項３）。   Further, the water discharge pipe and the attachment member can be made of metal, and can be welded all around to be joined to each other in a sealed state (Claim 3).

次に請求項４は、上記吐水口部材に、通水用の細孔を面状に分散形成して成るストレーナを整流部材として水路を横切る状態に保持させたもので、この請求項４によれば、整流部材として働くストレーナにより、吐水口部材の吐水口からの吐水を整流状態で綺麗な吐水として吐出させることができる。   Next, a fourth aspect of the present invention is that the water outlet member is held in a state of crossing the water channel by using a strainer formed by dispersing and forming fine pores for passing water in a planar shape as a rectifying member. In this case, the water discharged from the water discharge port of the water discharge port member can be discharged as clean water discharge in a rectified state by the strainer that functions as the flow straightening member.

請求項５は、内周形状が横長の矩形状をなす角パイプ材を用いて吐水パイプを構成し、そして吐水口の形状を、左右方向に横長の扁平形状をなし、吐水を滝状に吐出する滝口吐水口となしたもので、この請求項５によれば、吐水口から見た目に美しい滝状の吐水を吐出することができる。   According to claim 5, the water discharge pipe is configured by using a rectangular pipe material whose inner peripheral shape is a horizontally long rectangular shape, and the shape of the water discharge port is a horizontally long flat shape in the left-right direction, and the water discharge is discharged in a waterfall shape. According to claim 5, it is possible to discharge waterfall-like water discharge that is beautifully seen from the water outlet.

請求項６は、吐水口部材を抜止状態に固定するための固定手段を、吐水パイプの外部から操作可能で、吐水口部材を脱着可能に固定するものとなしたもので、この請求項６によれば、吐水口部材をメンテナンスする必要が生じたとき、吐水口部材を簡単に吐水パイプから外部に取り出してメンテナンス作業することができる。   According to a sixth aspect of the present invention, a fixing means for fixing the water discharge port member in a retaining state can be operated from the outside of the water discharge pipe, and the water discharge port member is fixed detachably. According to this, when it becomes necessary to maintain the spout member, the spout member can be easily taken out from the spout pipe to perform maintenance work.

特に請求項４に従って吐水口部材にストレーナを整流部材として保持させてある場合、このストレーナには細かな砂その他の異物が付着して目詰まりを生じることがあり、この場合吐水口部材を取り外すことによってストレーナを掃除し、目詰まりを解消するための作業を簡単に行うことができる。
ストレーナが目詰まりを生じていると、ストレーナによる整流作用が良好に行われず、吐水が乱れたものとなってしまって、吐水の美観が損なわれてしまう。 In particular, when the strainer is held as a rectifying member in the water outlet member according to claim 4, fine sand or other foreign matter may adhere to the strainer and cause clogging. In this case, the water outlet member is removed. This makes it easy to clean the strainer and eliminate clogging.
When the strainer is clogged, the rectifying action by the strainer is not performed well, and the discharged water is disturbed, and the aesthetic appearance of the discharged water is impaired.

特に請求項５に従って吐水口を滝口吐水口となし、吐水口からの吐水を滝状に吐出するようになしたものにおいては、ストレーナに目詰まりが生じると、せっかくの見た目に綺麗な滝状の吐水が不完全な滝状吐水となって、僅かなストレーナの目詰まりによってもその美観が大きく損なわれてしまう問題が生ずる。
しかるに請求項６に従って吐水口部材を脱着可能としておくことで、吐水の美しさを常に所望の目的とする美しさに保持することができる。 In particular, in the case where the water outlet is formed as a waterfall outlet according to claim 5 and the water discharged from the water outlet is discharged in a waterfall shape, if the strainer is clogged, the waterfall looks beautiful. The water discharge becomes incomplete waterfall-like water discharge, and there is a problem in that the aesthetics are greatly impaired even by slight clogging of the strainer.
However, according to the sixth aspect, by allowing the water discharge port member to be detachable, the beauty of the water discharge can always be kept at the desired beauty.

この固定部材９０による吐水口部材４６の吐水パイプ４４への固定は次のようにして行われる。
即ち、図５に示しているように吐水口部材４６を吐水パイプ４４内部に挿入し、そして雄嵌合面６８を取付部材４８の雌嵌合面５８に嵌合させた状態の下で、固定部材９０を吐水パイプ４４の固定孔９２に押し込むと、一対の弾性爪９３がカム面９５のカム作用で互いに接近する方向に弾性変形し、その弾性変形を伴って固定部材９０が固定孔９２に嵌め込まれる。
このとき、吐水パイプ４４の固定孔９２を通過した一対の弾性爪９３が、カム面９６において固定孔９２の縁部に係合し、吐水パイプ４４に固定される。 The fixing member 90 fixes the water outlet member 46 to the water discharge pipe 44 as follows.
That is, as shown in FIG. 5, the spout member 46 is inserted into the spout pipe 44 and the male fitting surface 68 is fixed to the female fitting surface 58 of the mounting member 48. When the member 90 is pushed into the fixing hole 92 of the water discharge pipe 44, the pair of elastic claws 93 are elastically deformed in the direction approaching each other by the cam action of the cam surface 95, and the fixing member 90 is moved into the fixing hole 92 with the elastic deformation. It is inserted.
At this time, the pair of elastic claws 93 that have passed through the fixing hole 92 of the water discharge pipe 44 engage with the edge of the fixing hole 92 on the cam surface 96 and are fixed to the water discharge pipe 44.

またこのとき、固定部材９０の係合突部９４が吐水口部材４６の係合凹部８８の内部に入り込んで係合し、ここにおいて吐水口部材４６が吐水パイプ４４、具体的には取付部材４８から抜止状態に固定される。

It is fixed to the removal state.
The fixing member 90 can be easily removed when necessary, after being fixed to the water discharge pipe 44 in this manner.

詳しくは、固定部材９０の段付部９８にマイナスドライバー等の工具の先端部を当てて抜出方向の力を加えると、固定部材９０の一対の弾性爪９３がカム面９６のカム作用で互いに接近する方向で弾性変形して、吐水パイプ４４の固定孔９２に対する一対の弾性爪９３の係合が解除され、ここにおいて固定部材９０を吐水パイプ４４から外すことができる。
而して固定部材９０を外すことによって、吐水口部材４６を取付部材４８及び吐水パイプ４４から容易に外部へと抜き出すことができる。 Specifically, when a force in the extraction direction is applied to the stepped portion 98 of the fixing member 90 by applying the tip of a tool such as a flat-blade screwdriver, the pair of elastic claws 93 of the fixing member 90 are brought into contact with each other by the cam action of the cam surface 96. By elastically deforming in the approaching direction, the engagement of the pair of elastic claws 93 with the fixing hole 92 of the water discharge pipe 44 is released, and the fixing member 90 can be removed from the water discharge pipe 44 here.
Thus, by removing the fixing member 90, the water discharge port member 46 can be easily pulled out from the mounting member 48 and the water discharge pipe 44.

図８は、本実施形態における吐水口部材４６の取付けの手順を示している。
上述したようにこの実施形態では、図８（Ｉ）に示すように取付部材４８を溶接材料５６とともに吐水パイプ４４内部且つ一定深さの奥部まで挿入し、その状態で吐水管４４周りから溶接材料５６をバーナ等にて炙り加熱することで溶接材料５６を溶かし、取付部材４８を吐水パイプ４４に溶接接合する。 FIG. 8 shows a procedure for attaching the water outlet member 46 in the present embodiment.
As described above, in this embodiment, as shown in FIG. 8 (I), the attachment member 48 is inserted together with the welding material 56 to the inside of the water discharge pipe 44 and to a depth of a certain depth, and in that state, welding is performed from around the water discharge pipe 44. The material 56 is heated with a burner or the like to melt the welding material 56, and the attachment member 48 is welded to the water discharge pipe 44.

そしてその後、一対のストレーナ７４-１，７４-２をストレーナ保持部材７６にて吐水口部材４６に組み付けた状態の下で、吐水口部材４６を吐水パイプ４４の先端開口からその内部に挿入し、そして吐水口部材４６の雄嵌合面６８を、取付部材４８の雌嵌合面５８に嵌合させる。
そしてその後、固定部材９０を吐水パイプ４４の固定孔９２に嵌め込むことで、吐水口部材４６を吐水パイプ４４から抜止状態に且つ脱着可能に固定することができる。 Then, under the state where the pair of strainers 74-1 and 74-2 is assembled to the water discharge port member 46 by the strainer holding member 76, the water discharge port member 46 is inserted into the water discharge pipe 44 from the front end opening thereof, Then, the male fitting surface 68 of the water outlet member 46 is fitted to the female fitting surface 58 of the attachment member 48.
And then, by fitting the fixing member 90 into the fixing hole 92 of the water discharge pipe 44, the water discharge port member 46 can be fixed in a detachable state from the water discharge pipe 44.

この実施形態の場合、図２のホース３４を通じて吐水パイプ４４に送られた水は、吐水パイプ４４の内周面を直接の流水面として吐水パイプ４４に沿って先端側まで流れ、そして先ず吐水口部材４６に保持された一対のストレーナ７４-１，７４-２を通過して流れる。
このとき、水の流れは一対のストレーナ７４-１，７４-２によって２段階に整流され、吐水口部材４６の基端部位において先ずこれらストレーナ７４-１，７４-２によって流れが整えられる。 In the case of this embodiment, the water sent to the water discharge pipe 44 through the hose 34 in FIG. 2 flows to the tip side along the water discharge pipe 44 with the inner peripheral surface of the water discharge pipe 44 as a direct water flow surface, and first the water discharge port It flows through a pair of strainers 74-1 and 74-2 held by the member 46.
At this time, the flow of water is rectified in two stages by the pair of strainers 74-1 and 74-2, and the flow is first adjusted by the strainers 74-1 and 74-2 at the proximal end portion of the water discharge port member 46.

而して吐水パイプ４４を先端側に流れて来た水は、その途中での流速分布の不均一や流れの方向の分布の不均一さがこれら一対のストレーナ７４-１，７４-２を通過することで解消されて均等化され、その上で吐水口部材４６の吐水口６４の形状に応じて水流の形が整えられて、最終的に左右方向に扁平な形状をなす滝口の吐水口６４の先端（出口）から滝状の吐水として下方に吐出される。   Thus, the water flowing to the tip side of the water discharge pipe 44 passes through the pair of strainers 74-1 and 74-2 due to non-uniform flow velocity distribution and non-uniform flow direction distribution along the way. The water flow shape is adjusted in accordance with the shape of the water discharge port 64 of the water discharge port member 46, and finally the water discharge port 64 of the waterfall port that has a flat shape in the left-right direction. It is discharged downward as waterfall-like water discharge from the tip (exit).

以上のような本実施形態によれば、内周形状が横長の矩形状をなす角パイプ材を用いて吐水パイプ４４を構成しつつ、これに吐水口部材４６を取り付けることにより、吐水装置２２における吐水口６４を角パイプ材の内周形状とは異なった吐水口形状となすことができるとともに、Ｏリング７２を径方向に弾性圧縮させることで、良好に吐水口部材４６と吐水パイプ４４との間を取付部材４８を介して水密シール状態とすることができる。   According to the present embodiment as described above, the water discharge pipe 44 is configured by using the rectangular pipe material whose inner peripheral shape is a horizontally long rectangular shape, and the water discharge port member 46 is attached to the water discharge pipe member 44. The water outlet 64 can be formed into a water outlet shape different from the inner peripheral shape of the square pipe material, and the O-ring 72 is elastically compressed in the radial direction, so that the water outlet member 46 and the water discharge pipe 44 can be well formed. The space can be in a watertight seal state via the attachment member 48.

また径方向に弾性圧縮してシール作用するＯリング７２を用いることができるため、吐水口部材４６と吐水パイプ４４とでシール部材を管軸方向に弾性圧縮してシールする場合のように、シール部材を管軸方向に弾性圧縮し且つ圧縮状態を維持するためのねじ等を吐水口６４の先端面からねじ込まなくてもよく、即ちねじ等のねじ込みのためのスペースを吐水口６４の先端面に確保しなくてもよく、これにより吐水口６４の先端面に吐水口６４のためのスペースを十分に確保することが可能となって、容易に所望の滝口の吐水口形状を実現することができる。   In addition, since an O-ring 72 that acts as a seal by elastically compressing in the radial direction can be used, the seal member is sealed by elastically compressing the seal member in the tube axis direction by the water discharge port member 46 and the water discharge pipe 44. A screw or the like for elastically compressing the member in the tube axis direction and maintaining the compressed state may not be screwed from the front end surface of the water discharge port 64, that is, a space for screwing the screw or the like is provided in the front end surface of the water discharge port 64. This does not have to be ensured, and as a result, a sufficient space for the spout 64 can be secured on the front end surface of the spout 64, and a desired waterfall shape of the waterfall can be easily realized. .

また吐水口部材４６には、ストレーナ７４-１，７４-２を整流部材として水路を横切る状態に保持させているため、吐水口６４からの吐水を整流状態で綺麗な滝状の流れとして吐出させることができる。   Further, since the water outlet member 46 holds the strainers 74-1 and 74-2 as rectifying members so as to cross the water channel, the water discharged from the water outlet 64 is discharged as a beautiful waterfall-like flow in the rectified state. be able to.
