Description

本発明は、蛇口等の給水口に取り付けられ、吐水量を自在に調節することができる節水器具に関する。   The present invention relates to a water-saving device that is attached to a water supply port such as a faucet and that can freely adjust the water discharge amount.

本件出願人は、先に、下記特許文献１記載の節水器具を提案している。この節水器具では、ケーシング内に、減圧コマと節水コマと順に配設し、減圧コマで蛇口からの流水の圧力を減圧し、減圧コマと節水コマとの間の空間部で水を滞留させてから節水コマの吐水孔より水を吐出するようにしている。減圧コマは、蛇口からの流水を絞る絞り部材としても機能するものであり、吐水孔へ供給する水量を決定するものとなる。   The present applicant has previously proposed a water-saving device described in Patent Document 1 below. In this water-saving device, a decompression piece and a water-saving piece are arranged in this order in the casing, the pressure of the flowing water from the faucet is reduced by the pressure reduction piece, and water is retained in the space between the pressure reduction piece and the water-saving piece. The water is discharged from the water discharge hole of the water-saving top. The decompression piece also functions as a throttle member that squeezes running water from the faucet, and determines the amount of water supplied to the water discharge hole.

また、特許文献１の節水器具では、水圧を調節することで節水を行うようにし、水圧が低減されることで、吐出孔から吐出される水流が飛散し、周囲が汚損することを防止するようにしている。   Further, in the water-saving device of Patent Document 1, water is saved by adjusting the water pressure, and the water pressure is reduced, so that the water flow discharged from the discharge hole is scattered and the surroundings are prevented from being soiled. I have to.

国際公開第２００９／０４４７０３号International Publication No. 2009/044703

ところで、蛇口での水圧は、その建物の給水設備、階数等によってバラツキがあり、同じではない。また、厨房設備の蛇口であるのか、洗面所の蛇口であるのか、等の用途によっても、求められる水量や水圧は異なる。更に、蛇口からの水量や水圧の好みは、使用者によっても異なる。   By the way, the water pressure at the faucet varies depending on the water supply equipment, floor number, etc. of the building and is not the same. Also, the required amount of water and water pressure differ depending on the use, such as whether it is a faucet for a kitchen facility or a toilet faucet. Furthermore, the preference of the amount of water from the faucet and the water pressure varies depending on the user.

上述した特許文献１に記載の一形態の節水器具では、このような要求に応えるため、様々な種類の減圧コマを予め用意しておき、予め用意した減圧コマの中から所望の減圧コマを選択する必要がある。施工場所に応じて減圧コマを選択する作業は、熟練を要する作業であり、減圧コマの交換作業は、節水器具の分解組立を改めて行う必要があり、面倒な作業となる。一般に、節水器具の取付作業は、施設稼働中となるため、なるべく短期間に行う必要がある。   In the water-saving device according to one embodiment described in Patent Document 1 described above, in order to meet such a demand, various types of decompression frames are prepared in advance, and a desired decompression frame is selected from the prepared decompression frames. There is a need to. The operation of selecting the decompression piece according to the construction site is an operation that requires skill, and the replacement operation of the decompression piece requires a disassembly and assembly of the water-saving device, which is troublesome. In general, the installation work of the water-saving device is in a short period of time as possible because the facility is in operation.

また、吐出孔より吐出される水が飛散することを防止するには、水圧の他、吐出方向の制御も水圧や水量との関係で重要である。例えば、洗面化粧台の洗面器に対して吐水されるとき、水圧が高く水量が多すぎると、水滴が洗面器の外にまで飛散してしまうおそれがある。特に、洗面器の上の方に向かって吐水されたときには、水滴が洗面器の外にまで飛散し易い。   In addition, in order to prevent water discharged from the discharge holes from being scattered, control of the discharge direction in addition to the water pressure is important in relation to the water pressure and the amount of water. For example, when water is discharged to the wash basin of the vanity, if the water pressure is high and the amount of water is too large, there is a possibility that water droplets may be scattered outside the wash basin. In particular, when water is discharged toward the top of the basin, water droplets are likely to scatter out of the basin.

A nozzle member 31 is engaged with the mounting step portion 15 to prevent the nozzle portion 31 from falling off the water discharge side opening 13. The throttle member 21 is disposed on the nozzle member 31 in the casing 11.

［絞り部材の説明］
絞り部材２１は、図１−図３に示すように、略円柱状に形成され、上下に、フランジ部２２，２３が形成されている。絞り部材２１は、上側のフランジ２２が設けられた上面略中央部に、通水孔となる第一の孔部２４が厚さ方向に貫通して形成されている。第一の孔部２４は、ここでは四つ等間隔に四角形の頂部位置の配位で設けられ、水流が安定となるように形成されている。なお、第一の孔部２４は、この例に特に限定されるものではなく、例えば各孔部の水流が安定になるように構成されていれば、数や形状や大きさは特に限定されるものではない。複数の第一の孔部２４は、蛇口２の給水口３から供給される水の流量を制限するようにしている。 [Explanation of diaphragm member]
As shown in FIGS. 1 to 3, the aperture member 21 is formed in a substantially cylindrical shape, and flange portions 22 and 23 are formed on the upper and lower sides. The throttle member 21 is formed with a first hole portion 24 serving as a water passage hole penetrating in the thickness direction at a substantially central portion of the upper surface where the upper flange 22 is provided. Here, the first hole portions 24 are provided at four equally spaced intervals in a quadrangular top position so that the water flow is stable. In addition, the 1st hole 24 is not specifically limited to this example, For example, if it is comprised so that the water flow of each hole may become stable, a number, a shape, and a size will be specifically limited. It is not a thing. The plurality of first holes 24 limit the flow rate of water supplied from the water supply port 3 of the faucet 2.

第一の孔部２４は、厚さ方向の全部に亘って形成されるのではなく、取付開口部１２側に寄って形成されており、絞り部材２１には、複数の第一の孔部２４に連続して、下流側のフランジ部２３の中央部を開口した略円筒状の接続凹部２５が形成されている。接続凹部２５には、ノズル部材３１の円筒部３２が嵌合されることになる。   The first hole 24 is not formed over the entire thickness direction, but is formed closer to the mounting opening 12, and the diaphragm member 21 has a plurality of first holes 24. A substantially cylindrical connecting recess 25 is formed continuously open at the center of the downstream flange 23. The cylindrical portion 32 of the nozzle member 31 is fitted into the connection recess 25.

複数の第一の孔部２４の周囲には、有底の環状凹部２６が形成されている。本発明において、この環状凹部２６は必ずしも必要なものではないが、樹脂成形を用いて絞り部材２１を形成する場合には、省材料化を図り得る上、成形による寸法安定性の悪化を抑制することが可能となる。   A bottomed annular recess 26 is formed around the plurality of first holes 24. In the present invention, the annular recess 26 is not necessarily required. However, when the diaphragm member 21 is formed by resin molding, material saving can be achieved and deterioration of dimensional stability due to molding can be suppressed. It becomes possible.

他方のフランジ部２３には、外周部に、下方に突出するスペーサ突部２７が環状に形成されている。スペーサ突部２７は、絞り部材２１の下側に配置されるノズル部材３１の位置決めをすると共に、絞り部材２１とノズル部材３１との間に減圧するための空間部２８を形成しつつ、絞り部材２１とノズル部材３１との接合部周辺の水密性を確保し、ノズル部材２１とケーシング１１との接触部周辺からの漏水を防止するように構成される。   On the other flange portion 23, a spacer protrusion 27 protruding downward is formed in an annular shape on the outer peripheral portion. The spacer protrusion 27 positions the nozzle member 31 disposed below the throttle member 21 and forms a space 28 for reducing the pressure between the throttle member 21 and the nozzle member 31, while the throttle member 27 It is configured to ensure water tightness around the joint between the nozzle 21 and the nozzle member 31 and to prevent water leakage from around the contact portion between the nozzle member 21 and the casing 11.

また、スペーサ突部２７の先端面には、突起２９が形成されている。突起２９は、後述するノズル部材３１に形成された複数の凹部に選択的に係合し、絞り部材２１に対するノズル部材３１の回転位置を視認しながら段階的に調節できるようにしている。   A protrusion 29 is formed on the tip surface of the spacer protrusion 27. The protrusion 29 selectively engages with a plurality of recesses formed in the nozzle member 31 described later, and can be adjusted stepwise while visually recognizing the rotational position of the nozzle member 31 relative to the diaphragm member 21.

［ノズル部材の説明］
ノズル部材３１は、図１、図２及び図４に示すように、略円柱状をなし、上面の中央部に円筒部３２が形成されている。勿論、ノズル部材の上面中央部に形成される円筒部３２は、必ずしも円筒状である必要はなく、例えば多角筒状をなすものとすることもでき、第一の孔部と第二の孔部と当接部周辺にある程度の水密性が得られるものであれば特に限定されるものではない。円筒部３２には、絞り部材２１の複数の第一の孔部２４に対応した第二の孔部３３が複数形成されている。各第二の孔部３３は、円筒部３２の先端面に、第一の孔部２４に繋がる入口３３ａが形成され、側面に出口３３ｂが形成され、流路が略Ｌ字をなすように形成されている。 [Description of nozzle member]
As shown in FIGS. 1, 2, and 4, the nozzle member 31 has a substantially columnar shape, and a cylindrical portion 32 is formed at the center of the upper surface. Of course, the cylindrical portion 32 formed at the center of the upper surface of the nozzle member does not necessarily have a cylindrical shape. For example, the cylindrical portion 32 may have a polygonal cylindrical shape, and the first hole portion and the second hole portion. As long as a certain level of watertightness can be obtained around the contact portion, there is no particular limitation. A plurality of second hole portions 33 corresponding to the plurality of first hole portions 24 of the throttle member 21 are formed in the cylindrical portion 32. Each second hole 33 is formed such that an inlet 33a connected to the first hole 24 is formed on the distal end surface of the cylindrical portion 32, an outlet 33b is formed on a side surface, and the flow path is substantially L-shaped. Has been.

なお、第二の孔部３３は、この例に特に限定されるものではなく、例えば各孔部の水流が安定になるように構成されていれば、数や形状や大きさは特に限定されるものではない。   In addition, the 2nd hole part 33 is not specifically limited to this example, For example, if it is comprised so that the water flow of each hole part may become stable, a number, a shape, and a size will be specifically limited. It is not a thing.

円筒部３２は、絞り部材２１の下流側に形成された接続凹部２５に嵌合される。これにより、絞り部材２１の第一の孔部２４とノズル部材３１の第二の孔部３３とは、水流方向に重なり、繋がることになる。したがって、第一及び第二の孔部２４，３３を通った水は、出口３３ｂよりノズル部材３１の上面に流出する。   The cylindrical portion 32 is fitted into a connection concave portion 25 formed on the downstream side of the throttle member 21. Accordingly, the first hole 24 of the throttle member 21 and the second hole 33 of the nozzle member 31 are overlapped and connected in the water flow direction. Therefore, the water that has passed through the first and second holes 24 and 33 flows out from the outlet 33b to the upper surface of the nozzle member 31.

ノズル部材３１の上面には、外周部に、係合段部３４が形成されている。係合段部３４は、絞り部材２１の下面に環状に形成されたスペーサ突部２７に係合される。これにより、ノズル部材３１は、絞り部材２１の下流側に空間部２８を作出した状態で位置決めされ、取り付けられる。また、係合段部３４は、絞り部材２１のスペーサ突部２７が係合されることで、絞り部材２１とノズル部材３１との間の水密性を確保すると共に、絞り部材２１に対してノズル部材３１を、絞り部材２１の接続凹部２５に嵌合された円筒部３２を中心に回転する際のガイド部として機能する。   On the upper surface of the nozzle member 31, an engagement step portion 34 is formed on the outer peripheral portion. The engaging step 34 is engaged with a spacer protrusion 27 formed in an annular shape on the lower surface of the throttle member 21. Thereby, the nozzle member 31 is positioned and attached in a state where the space portion 28 is created on the downstream side of the throttle member 21. Further, the engagement step portion 34 ensures water-tightness between the throttle member 21 and the nozzle member 31 by engaging the spacer protrusion 27 of the throttle member 21, and the nozzle with respect to the throttle member 21. The member 31 functions as a guide portion when rotating around the cylindrical portion 32 fitted in the connection recess 25 of the aperture member 21.

また、円筒部３２の外形を多角筒状とし、これに対応して絞り部材３１の接続凹部２５の内形を多角柱状に形成した場合には、絞り部材２１とノズル部材３１との相対回転の調整の都度、互いを離間させて抜き出さなければならないが、離脱させない限り互いの位置ずれが生じることもなくなるという効果が得られる。したがって、この場合、外部からの意図しない作用などによって吐水量が変わってしまうおそれがない。   When the outer shape of the cylindrical portion 32 is a polygonal cylinder and the inner shape of the connection recess 25 of the throttle member 31 is formed in a polygonal column corresponding to this, the relative rotation between the throttle member 21 and the nozzle member 31 is reduced. Each time adjustment is performed, they must be separated from each other, and there is an effect that no mutual displacement occurs unless they are separated. Therefore, in this case, there is no possibility that the water discharge amount may change due to an unintended action from the outside.

係合段部３４が形成されている部分は、フランジ部３５となっており、このフランジ部３５は、ケーシング１１の取付段部１５によって、下側から支持される。   The portion where the engaging step portion 34 is formed is a flange portion 35, and this flange portion 35 is supported from below by the mounting step portion 15 of the casing 11.

ノズル部材３１には、上流面から吐水面３１ａとなる下流面に亘って複数の吐水孔３６が形成されている。吐水孔３６は、係合段部３４の内側に形成され、第二の孔部３３の出口３３ｂとは離れた位置に形成されている。この吐水孔３６は、ノズル部材３１の外周側に環状に一列形成されているが、列の数は、二列、三列等複数列であっても良い。   The nozzle member 31 has a plurality of water discharge holes 36 extending from the upstream surface to the downstream surface serving as the water discharge surface 31a. The water discharge hole 36 is formed inside the engaging step portion 34 and is formed at a position away from the outlet 33 b of the second hole portion 33. The water discharge holes 36 are formed in a row on the outer peripheral side of the nozzle member 31, but the number of rows may be a plurality of rows such as two rows or three rows.

ノズル部材３１の下流面、すなわちケーシング１１の吐水側開口部１３より外部に臨む吐水面３１ａは、平坦に形成しても良いが、ここでは、中心が最も窪んだ断面がサイクロイド曲線を描くような曲面といった凹部で形成されている。吐水面３１ａをサイクロイド曲線を描くような曲面で形成したときには、吐水孔３６より吐水される水流がやや広がり、ケーシング１１の吐水側開口部１３より吐水される水流全体を太く見せることができる。   The downstream surface of the nozzle member 31, that is, the water discharge surface 31 a facing the outside from the water discharge side opening 13 of the casing 11 may be formed flat, but here, the cross-section where the center is most depressed draws a cycloid curve. It is formed with a concave portion such as a curved surface. When the water discharge surface 31a is formed as a curved surface that draws a cycloid curve, the water flow discharged from the water discharge hole 36 is slightly spread, and the entire water flow discharged from the water discharge side opening 13 of the casing 11 can be made thick.

また、ノズル部材３１のフランジ部３５には、凹部３７が複数、ここでは四つ形成されている。凹部３７は、フランジ部３５の上流面と側面を開口して形成され、上流面からの深さが異なるように形成されている。具体的に、一端側の凹部３７ａが最も浅く形成され、凹部３７ｂ、凹部３７ｃと順に深くなり、凹部３７ｄが最も深く形成されている。これら凹部３７ａ−３７ｄには、絞り部材２１のスペーサ突部２７の先端面の突起２９が選択的に係合される。突起２９は、隣接する凹部３７に移動するとき、凹部３７間を乗り上げる際にクリック感を発生させ、使用者に、何段階ノズル部材３１を回転させたのかを認識できるようにする。また、ケーシング１１の周回方向に、突起２９と凹部３７とを外部に臨ませるように、開口部を設けることで、使用者がどの凹部に突起２９が係合しているかを目視により確認できるようにすることができる。   Further, the flange portion 35 of the nozzle member 31 is formed with a plurality of concave portions 37, four in this case. The concave portion 37 is formed by opening the upstream surface and the side surface of the flange portion 35, and is formed so that the depth from the upstream surface is different. Specifically, the concave portion 37a on one end side is formed to be the shallowest, the concave portion 37b and the concave portion 37c are sequentially deepened, and the concave portion 37d is formed to be the deepest. The protrusions 29 on the front end surface of the spacer protrusion 27 of the throttle member 21 are selectively engaged with the recesses 37a to 37d. When the protrusion 29 moves to the adjacent concave portion 37, a click feeling is generated when climbing between the concave portions 37 so that the user can recognize how many nozzle members 31 have been rotated. Further, by providing an opening so that the protrusion 29 and the recess 37 face the outside in the circumferential direction of the casing 11, the user can visually confirm which recess the protrusion 29 is engaged with. Can be.

なお、絞り部材２１とノズル部材３１とは、相対的に何れかが回転すれば良く、絞り部材２１が回転するようにしても良い。   It should be noted that any one of the diaphragm member 21 and the nozzle member 31 may be rotated relatively, and the diaphragm member 21 may be rotated.

［節水器具の組立］
以上のように構成された節水器具１は、次のように組み立てられる。先ず、図５に示すように、絞り部材２１とノズル部材３１とは、絞り部材２１の接続凹部２５に、ノズル部材３１の円筒部３２を嵌合し、絞り部材２１のスペーサ突部２７を、ノズル部材３１の係合段部３４に係合させることによって組み合わされる。この際、絞り部材２１の突起２９を何れかの凹部３７に係合させる。 [Assembly of water-saving equipment]
The water-saving device 1 configured as described above is assembled as follows. First, as shown in FIG. 5, the throttle member 21 and the nozzle member 31 are fitted with the cylindrical portion 32 of the nozzle member 31 in the connection recess 25 of the throttle member 21, and the spacer protrusion 27 of the throttle member 21 is The nozzle members 31 are combined by engaging with the engaging step 34. At this time, the protrusion 29 of the aperture member 21 is engaged with any one of the recesses 37.

この後、絞り部材２１が組み合わされたノズル部材３１は、ケーシング１１内の取付段部１５に、フランジ部３５を係合させて、ケーシング１１内において、下側から支持されるようにして取り付けられる。   Thereafter, the nozzle member 31 combined with the throttle member 21 is attached so as to be supported from the lower side in the casing 11 by engaging the flange portion 35 with the attachment step portion 15 in the casing 11. .

次いで、ケーシング１１には、取付開口部１２側の取付凹部１４にリング状のパッキン１４ａが係合される。ここでは、パッキン１４ａは絞り部材２１とは別体に設けられているが絞り部材２１と一体的に設けても良い。この後、ケーシング１１は、蛇口２にねじ止めされる。パッキン１４ａは、蛇口２が圧接されることで、蛇口２とケーシング１１との間の水密性を確保して水漏れを防止する。   Next, in the casing 11, a ring-shaped packing 14 a is engaged with the mounting recess 14 on the mounting opening 12 side. Here, the packing 14 a is provided separately from the throttle member 21, but may be provided integrally with the throttle member 21. Thereafter, the casing 11 is screwed to the faucet 2. The packing 14a presses the faucet 2 to ensure water tightness between the faucet 2 and the casing 11 to prevent water leakage.

［節水器具の動作］
以上のような節水器具１は、蛇口２の給水口３から水が供給されると、水が絞り部材２１の第一の孔部２４とノズル部材３１の第二の孔部３３を通って絞り部材２１とノズル部材３１との間の空間部２８に供給される。空間部２８には、第一及び第二の孔部２４，３３で水量が絞られて供給されることになる。そして、水流は、第二の孔部３３で水流の方向が曲げられ、また、空間部２８で、第二の孔部３３の出口３３ｂから流出する水流が互いに衝合することで、水圧が減圧される。この後、減圧された水は、ノズル部材３１の吐水孔３６から吐水される。 [Operation of water-saving equipment]
In the water-saving device 1 as described above, when water is supplied from the water supply port 3 of the faucet 2, the water is throttled through the first hole 24 of the throttle member 21 and the second hole 33 of the nozzle member 31. It is supplied to the space 28 between the member 21 and the nozzle member 31. The space 28 is supplied with the amount of water reduced by the first and second holes 24 and 33. Then, the direction of the water flow is bent at the second hole 33, and the water flow flowing out from the outlet 33b of the second hole 33 abuts with each other in the space 28, whereby the water pressure is reduced. Is done. Thereafter, the decompressed water is discharged from the water discharge hole 36 of the nozzle member 31.

・水量調節
水量調節は、ノズル部材３１を絞り部材２１に対して回転させることにより行われる。具体的に、絞り部材２１の第一の孔部２４と第二の孔部３３の入口３３ａとが最も重なっているときは、最も絞りが開いた状態であり、水量も最も大きくなる。そして、図６（Ａ）、図６（Ｂ）に示すように、第一の孔部２４と第二の孔部３３の入口３３ａとの重なり度合いが小さくなると、その分、流路が小さくなり、水量が絞られることになる。図６（Ｃ）は、第一の孔部２４と第二の孔部３３の入口３３ａとが最もずれ、最も水量が絞られた状態となる。更に、ノズル部材３１を絞り部材２１に対して相対回転させると図６（Ｄ）に示すように再び開口量が大きくなり、図６（Ｂ）と同等程度の開口量となり、回転に合わせて順次開口量が段階的に変化するようになっている。 -Water quantity adjustment Water quantity adjustment is performed by rotating the nozzle member 31 with respect to the throttle member 21. Specifically, when the first hole 24 of the throttle member 21 and the inlet 33a of the second hole 33 overlap most, the throttle is most open and the amount of water is the largest. As shown in FIGS. 6A and 6B, when the degree of overlap between the first hole 24 and the inlet 33a of the second hole 33 is reduced, the flow path is reduced accordingly. The amount of water will be reduced. In FIG. 6C, the first hole 24 and the inlet 33a of the second hole 33 are shifted most, and the amount of water is reduced most. Further, when the nozzle member 31 is rotated relative to the aperture member 21, the opening amount increases again as shown in FIG. 6D, and the opening amount becomes approximately the same as that in FIG. 6B. The opening amount changes in steps.

図６に示すような開口量の段階的な切り替えは、ノズル部材３１を回転させることによって行われるものであり、絞りが最も開いた状態では、絞り部材２１の突起２９がノズル部材３１の最も浅い凹部３７ａに係合される。絞りが順に閉じるに連れ、突起２９は、順に、凹部３７ｂ，３７ｃに係合され、図６（Ｃ）に示すように、絞りが最も閉じたとき、最も深い凹部３７ｄに係合される。このように、水量調節後の設定状態は、突部２９が選択的に３７ａ−３７ｄの何れかに係合することで保持されることになる。   The stepwise switching of the opening amount as shown in FIG. 6 is performed by rotating the nozzle member 31, and the protrusion 29 of the throttle member 21 is the shallowest of the nozzle member 31 in the state where the throttle is most open. Engage with the recess 37a. As the diaphragm is sequentially closed, the protrusion 29 is sequentially engaged with the recesses 37b and 37c, and as shown in FIG. 6C, when the diaphragm is closed most, it is engaged with the deepest recess 37d. As described above, the setting state after the water amount adjustment is maintained by selectively engaging the protrusion 29 with any of 37a to 37d.

このノズル部材３１の回転操作の方法は特に限定されるものではなく、節水器具１が分解された状態において、絞り部材２１に対してノズル部材３１を回転させても良い他、分解するまでもなく、組立後の状態において、指や治具を使って、ケーシング１１の吐水側開口部１３より臨むノズル部材３１を回転させても良い。更に、ノズル部材３１に、ケーシング１１より外部に臨む操作突起を設けて、この操作突起を用いてノズル部材３１を回転させても良い。   The method for rotating the nozzle member 31 is not particularly limited, and the nozzle member 31 may be rotated with respect to the throttle member 21 in a state where the water-saving device 1 is disassembled, and it is not necessary to disassemble the nozzle member 31. In a state after assembly, the nozzle member 31 facing the water discharge side opening 13 of the casing 11 may be rotated using a finger or a jig. Furthermore, the nozzle member 31 may be provided with an operation projection facing the outside from the casing 11, and the nozzle member 31 may be rotated using the operation projection.

［節水器具の効果］
以上のような節水器具１によれば、ノズル部材３１と絞り部材２１とを相対回転させることよって、第一の孔部２４と第二の孔部３３の入口３３ａの重なり度合いを容易に調節することができる。すなわち、水量の絞り調整をノズル部材３１を回転させるだけで行うことができる。このように、節水器具１は、節水器具１を取り付ける場所や用途に応じて適宜吐水量調節を容易に行うことができる。また、吐水量調節を容易に行うことができるので、従来のように、吐水量を調節するための減圧コマ等を多数用意しておく必要がなくなる。また、絞り部材２１の突起２９をノズル部材３１の凹部３７に選択的に係合させることで、絞りの調整作業を段階的乃至連続的に行うことができ、水量の調節作業を容易に行うことができる。 [Effect of water-saving equipment]
According to the water-saving device 1 as described above, the degree of overlap between the first hole 24 and the inlet 33a of the second hole 33 is easily adjusted by rotating the nozzle member 31 and the throttle member 21 relative to each other. be able to. That is, the adjustment of the amount of water can be performed only by rotating the nozzle member 31. As described above, the water-saving device 1 can easily adjust the water discharge amount appropriately according to the place and application where the water-saving device 1 is attached. Further, since the water discharge amount can be easily adjusted, there is no need to prepare a large number of decompression frames and the like for adjusting the water discharge amount as in the prior art. In addition, by selectively engaging the protrusions 29 of the throttle member 21 with the recesses 37 of the nozzle member 31, the throttle adjustment operation can be performed stepwise or continuously, and the water amount adjustment operation can be easily performed. Can do.

なお、絞りの調節を段階的に行わない場合には、突起２９と凹部３７を設けないようにすればよい。特に、円筒部３２の外形を多角筒状とし、これに対応して絞り部材３１の接続凹部２５の内形を多角柱状に形成した場合には、位置ずれが発生しにくいため、突起２９と凹部３７を設けないようにしても良い。また、複数の凹部３７の間隔は、一定でなくても良い。   In the case where the adjustment of the diaphragm is not performed step by step, the protrusion 29 and the concave portion 37 may be omitted. In particular, when the outer shape of the cylindrical portion 32 is a polygonal cylinder and the inner shape of the connection recess 25 of the diaphragm member 31 is formed in a polygonal column corresponding to the outer shape, misalignment hardly occurs. 37 may not be provided. Further, the intervals between the plurality of recesses 37 may not be constant.

［節水器具の変形例］
以下、本発明の変形例となる節水器具について図面を参照して説明する。 [Variation of water-saving equipment]
Hereinafter, a water-saving device as a modification of the present invention will be described with reference to the drawings.

［全体構成］
図７−図９に示すように、本発明が適用された節水器具１０１は、水道の蛇口１０２の給水口１０３に取り付けられるケーシング１１１と、蛇口１０２の給水口１０３より給水される吐水量を絞る絞り部材１２１と、水を吐出するノズル部材１３１と、ケーシング１１１内に配設されて蛇口１０２とケーシング１１１との間の水漏れを防止する水密用のパッキン１５１とを備えている。 [overall structure]
As shown in FIGS. 7 to 9, the water-saving device 101 to which the present invention is applied restricts the amount of water discharged from the casing 111 attached to the water supply port 103 of the tap 102 and the water supply port 103 of the tap 102. A throttle member 121, a nozzle member 131 that discharges water, and a watertight packing 151 that is disposed in the casing 111 and prevents water leakage between the faucet 102 and the casing 111 are provided.

［ケーシングの説明］
ケーシング１１１は、図７−図１０に示すように、筒状に形成され、一端が、蛇口１０２等の給水口１０３に取り付けられる取付開口部１１２となっており、他端が、水を吐出する側として構成される吐水側開口部１１３となっている。取付開口部１１２の内周面には、ねじ溝１１２ａが形成されており、蛇口１０２のねじ部に締め付けることによって、ケーシング１１１が蛇口１０２等に取り付くようになっている。勿論、ねじ溝１１２ａの形成部位は、取付開口部１１２の内周面に限らず、例えば外周面であっても良く、また、給水口１０３に対してケーシング１１１を取り付ける手段は、ねじ溝に限定されるものでもない。 [Description of casing]
As shown in FIGS. 7 to 10, the casing 111 is formed in a cylindrical shape, and one end is a mounting opening 112 attached to the water supply port 103 such as the faucet 102, and the other end discharges water. It becomes the water discharge side opening part 113 comprised as a side. A thread groove 112 a is formed on the inner peripheral surface of the mounting opening 112, and the casing 111 is attached to the faucet 102 or the like by being fastened to the threaded portion of the faucet 102. Of course, the formation site of the screw groove 112a is not limited to the inner peripheral surface of the attachment opening 112, but may be, for example, the outer peripheral surface, and the means for attaching the casing 111 to the water supply port 103 is limited to the screw groove. It is not what is done.

このケーシング１１１内の空間部には、上述した絞り部材１２１とノズル部材１３１とパッキン１５１とが内蔵されることになる。吐水側開口部１１３の近傍には、段部１１４が形成され、パッキン１５１の吐水側開口部１１３側に位置する先端部が係合する。パッキン１５１は、吐水側開口部１１３側に位置する先端部が段部１１４に係合することによって、ケーシング１１１内に位置決めされた状態で取り付けられる。   In the space in the casing 111, the above-described throttle member 121, nozzle member 131, and packing 151 are incorporated. A step 114 is formed in the vicinity of the water discharge side opening 113, and a tip portion of the packing 151 located on the water discharge side opening 113 side is engaged. The packing 151 is attached in a state of being positioned in the casing 111 by engaging a tip portion located on the water discharge side opening 113 side with the stepped portion 114.

吐水側開口部１１３は、後述する絞り部材１２１とノズル部材１３１の組立体１５４を支持する球面支持部１１３ａを有し、更に、先端側に向かって拡径する吐水口１１３ｂが形成されている。球面支持部１１３ａは、後述するパッキン１５１の拡径部１５３の曲面と同じ曲率の曲面となっており、組立体１５４をノズル部材１３１の吐水面１３１ａ近傍で支持し、組立体１５４が吐水側開口部１１３より脱落しないようにする。すなわち、この球面支持部１１３ａは、組立体１５４の最大直径より小さい直径部を有しており、外方に向かって凸状の球面状座面に構成される。また、吐水口１１３ｂは、外方に向かって拡径した形状に形成されることで、吐水面１３１ａを傾斜させた際にもノズル部材１３１の吐水面１３１ａより吐水される水流が吐水側開口部１１３の周縁に触れないようにしている。   The water discharge side opening 113 has a spherical surface support portion 113a that supports an assembly 154 of a throttle member 121 and a nozzle member 131, which will be described later, and further has a water discharge port 113b that increases in diameter toward the tip side. The spherical support portion 113a has a curved surface having the same curvature as the curved surface of the enlarged diameter portion 153 of the packing 151, which will be described later, and supports the assembly 154 in the vicinity of the water discharge surface 131a of the nozzle member 131, and the assembly 154 has a water discharge side opening. Do not fall off from the portion 113. That is, the spherical surface support portion 113a has a diameter portion smaller than the maximum diameter of the assembly 154, and is configured as a spherical seat surface convex outward. In addition, the water discharge port 113b is formed in a shape whose diameter is increased outward, so that the water flow discharged from the water discharge surface 131a of the nozzle member 131 when the water discharge surface 131a is inclined allows the water discharge side opening. The periphery of 113 is not touched.

［絞り部材の説明］
絞り部材１２１は、図７−図９及び図１１に示すように、略椀形をなし、外側の湾曲面の頂部に、突出部１２２が形成されている。この突出部１２２には、中央部に、厚さ方向に貫通した通水孔１２３が形成されている。この通水孔１２３は、下流側に向かって凸状に形成された略円錐状の発条底部１２３ａを有し、この発条底部１２３ａには、上流側から下流側に向かって貫通した複数の第一の孔部１２４が穿孔されている。複数の第一の孔部１２４は、同じ大きさの孔で等間隔に穿孔され、ここでは四つ等間隔に四角形の頂部位置の配位で設けられている。 [Explanation of diaphragm member]
As shown in FIGS. 7 to 9 and 11, the throttle member 121 has a substantially bowl shape, and a protrusion 122 is formed on the top of the outer curved surface. The protruding portion 122 has a water passage hole 123 penetrating in the thickness direction at the center. The water passage hole 123 has a substantially conical ridge bottom portion 123a formed in a convex shape toward the downstream side. The ridge bottom portion 123a includes a plurality of first holes penetrating from the upstream side toward the downstream side. The hole 124 is perforated. The plurality of first hole portions 124 are perforated at equal intervals by holes of the same size, and here, four first hole portions 124 are provided at four equal intervals and arranged in a square top position.

なお、第一の孔部１２４は、この例に特に限定されるものではなく、例えば各孔部の水量が均等になるように構成されていれば、数や形状や大きさは特に限定されるものではない。通水孔１２３は、複数の第一の孔部１２４によって構成することで、蛇口１０２の給水口１０３から供給される水の流量を調節可能に制限するようにしている。   In addition, the 1st hole 124 is not specifically limited to this example, For example, if it is comprised so that the amount of water of each hole may become equal, a number, a shape, and a size will be specifically limited. It is not a thing. The water passage hole 123 is configured by a plurality of first hole portions 124, thereby restricting the flow rate of water supplied from the water supply port 103 of the faucet 102 so as to be adjustable.

また、外側の湾曲面の反対側の底面には、通水孔１２３の周囲に複数の閉塞突起１２５が複数形成され、後述のノズル部材１３１からの水の吐出量を制御するための閉塞手段とされる。閉塞突起１２５は、通水孔１２３を中心にして、環状に等間隔に形成されている。閉塞突起１２５は、次に説明するノズル部材１３１の吐水孔１３２を選択的に閉塞する。   In addition, a plurality of closing protrusions 125 are formed around the water passage hole 123 on the bottom surface opposite to the outer curved surface, and blocking means for controlling the amount of water discharged from the nozzle member 131 described later. Is done. The closing protrusions 125 are formed annularly at equal intervals around the water passage hole 123. The closing protrusion 125 selectively closes the water discharge hole 132 of the nozzle member 131 described below.

更に、底面には、湾曲面に連続する環状のガイド片１２６が形成されている。ガイド片１２６の先端部には、内側に突出してガイド突起１２６ａが複数形成されている。ガイド突起１２６ａは、次に説明するノズル部材１３１のガイド溝１３３に係合することによって、絞り部材１２１に対してノズル部材１３１が回転し得るようにする。   Further, an annular guide piece 126 that is continuous with the curved surface is formed on the bottom surface. A plurality of guide protrusions 126 a are formed at the distal end portion of the guide piece 126 so as to protrude inward. The guide protrusion 126a engages with a guide groove 133 of the nozzle member 131 described below, so that the nozzle member 131 can rotate with respect to the aperture member 121.

［ノズル部材の説明］
ノズル部材１３１は、図７−図９及び図１２に示すように、略円柱状をなし、外周面が絞り部材１２１の湾曲面と同じ曲率で湾曲するように形成されている。このノズル部材１３１には、厚さ方向に貫通した多数の吐水孔１３２が形成されている。吐水孔１３２は、例えば直径が１ｍｍ弱の大きさとなっている。そして、ノズル部材１３１の底面が吐水面１３１ａとなっており、平坦に形成されている。具体的に、ノズル部材１３１には、複数の吐水孔１３２で構成される環状の外周吐水孔列１３２ａと内周吐水孔列１３２ｂとが同心円状に形成されている。外周吐水孔列１３２ａは、常時吐水される部分となり、内周吐水孔列１３２ｂは、絞り部材１２１の閉塞突起１２５によって選択的に閉塞される。 [Description of nozzle member]
As shown in FIGS. 7 to 9 and 12, the nozzle member 131 has a substantially cylindrical shape and is formed so that the outer peripheral surface is curved with the same curvature as the curved surface of the diaphragm member 121. The nozzle member 131 has a large number of water discharge holes 132 penetrating in the thickness direction. The water discharge hole 132 has a diameter of a little less than 1 mm, for example. The bottom surface of the nozzle member 131 is a water discharge surface 131a and is formed flat. Specifically, in the nozzle member 131, an annular outer peripheral water discharge hole row 132a and an inner peripheral water discharge hole row 132b formed by a plurality of water discharge holes 132 are formed concentrically. The outer peripheral water discharge hole row 132 a is a portion that is constantly discharged, and the inner peripheral water discharge hole row 132 b is selectively closed by the closing protrusion 125 of the throttle member 121.

なお、内周吐水孔列１３２ｂを構成する吐水孔１３２の孔径と外周吐水孔列１３２ａを構成する吐水孔１３２の孔径は、同じであっても良く、また、内周吐水孔列１３２ｂを構成する吐出孔１３２の方が大きくても良く、更に、内周吐水孔列１３２ｂを構成する吐水孔１３２の方が小さくても良い。   In addition, the hole diameter of the water discharge hole 132 which comprises the inner periphery water discharge hole row | line | column 132b and the hole diameter of the water discharge hole 132 which comprises the outer periphery water discharge hole row | line | column 132a may be the same, and the inner periphery water discharge hole row | line | column 132b is comprised. The discharge holes 132 may be larger, and the water discharge holes 132 constituting the inner peripheral water discharge hole row 132b may be smaller.

また、吐水面１３１ａは、平坦面の他、中心が最も窪んだ断面がサイクロイド曲線を描くような曲面といった凹部で形成しても良い。吐水面１３１ａをサイクロイド曲線を描くような曲面で形成したときには、吐水孔１３２より吐水される水流がやや広がり、ケーシング１１１の吐水側開口部１１３より吐水される水流全体を太く見せることができる。   In addition to the flat surface, the water discharge surface 131a may be formed by a concave portion such as a curved surface in which a cross section with the most depressed center draws a cycloid curve. When the water discharge surface 131a is formed in a curved surface that draws a cycloid curve, the water flow discharged from the water discharge hole 132 is slightly spread, and the entire water flow discharged from the water discharge side opening 113 of the casing 111 can be made thick.

具体的に、内周吐水孔列１３２ｂでは、図１３に示すように、内周吐水孔列１３２ｂを構成する各吐水孔１３２の入口に、閉塞突起１２５が係合する第一の係合凹部１３５が形成されている。また、隣接する吐水孔１３２同士の間には、閉塞突起１２５が係合する第二の係合凹部１３６が形成されている。図１３（Ａ）に示すように、閉塞突起１２５が吐水孔１３２と連続した第一の係合凹部１３５に係合しているときには、吐水孔１３２は閉塞され、内周吐水孔列１３２ｂからは吐水されない状態となる（節水位置）。一方、図１３（Ｂ）に示すように、閉塞突起１２５が吐水孔１３２，１３２の間の第二の係合凹部１３６に係合しているときには、吐水孔１３２は開放され、内周吐水孔列１３２ｂからも吐水される状態となる（準節水位置）。   Specifically, in the inner peripheral water discharge hole row 132b, as shown in FIG. 13, a first engagement recess 135 in which the closing protrusion 125 is engaged with the inlet of each water discharge hole 132 constituting the inner peripheral water discharge hole row 132b. Is formed. In addition, a second engaging recess 136 is formed between the adjacent water discharge holes 132 to which the closing protrusion 125 is engaged. As shown in FIG. 13A, when the closing protrusion 125 is engaged with the first engaging recess 135 continuous with the water discharge hole 132, the water discharge hole 132 is closed and the inner peripheral water discharge hole row 132b Water is not discharged (water saving position). On the other hand, as shown in FIG. 13B, when the closing protrusion 125 is engaged with the second engagement recess 136 between the water discharge holes 132, 132, the water discharge hole 132 is opened, and the inner peripheral water discharge hole. Water is discharged from the row 132b (quasi-water saving position).

ノズル部材１３１の外周上端部には、絞り部材１２１のガイド突起１２６ａが係合するガイド溝１３３が形成されている。ガイド溝１３３には、ガイド突起１２６ａが係合することで、絞り部材１２１に対してノズル部材１３１が回転するようになる。そして、絞り部材１２１に対してノズル部材１３１が回転することで、図１３（Ａ）に示す、内周吐水孔列１３２ｂから吐水されない状態と図１３（Ｂ）に示す内周吐水孔列１３２ｂからも吐水される状態とが切り替えられることになる。   A guide groove 133 that engages with the guide protrusion 126 a of the diaphragm member 121 is formed at the upper end of the outer periphery of the nozzle member 131. When the guide protrusion 126 a is engaged with the guide groove 133, the nozzle member 131 rotates with respect to the diaphragm member 121. Then, when the nozzle member 131 rotates with respect to the throttle member 121, the state where water is not discharged from the inner peripheral water discharge hole row 132b shown in FIG. 13A and the inner peripheral water discharge hole row 132b shown in FIG. 13B. The state where water is discharged is also switched.

なお、内周吐水孔列１３２ｂにおいて、隣接する吐水孔１３２同士の間に設ける第一の係合凹部１３５の数は、１つでも、複数であっても良い。また、閉塞突起１２５の数や間隔は、内周吐水孔列１３２ｂから吐出する吐水量の切換を何段階行うかによって決められるもので、本発明では特に限定されるものではない。また、同心円状に設けられる環状の吐水孔列は、２つに限定されるものではなく、１つでも、３つ以上であっても良い。吐出孔列が１つの場合は、選択的に幾つかの吐水孔が閉塞突起に閉塞される構成となる。また、吐水孔列を３つ以上設けた場合には、すべて又は幾つかの吐水孔列の吐水孔が、閉塞突起によって選択的に閉塞されるようにすれば良い。   In the inner circumferential water discharge hole row 132b, the number of the first engaging recesses 135 provided between the adjacent water discharge holes 132 may be one or plural. Further, the number and interval of the blocking protrusions 125 are determined by the number of steps of switching the water discharge amount discharged from the inner peripheral water discharge hole row 132b, and are not particularly limited in the present invention. Further, the number of annular water discharge hole rows provided concentrically is not limited to two, and may be one or three or more. When there is one discharge hole array, some water discharge holes are selectively closed by the closing protrusions. Further, when three or more water discharge hole rows are provided, the water discharge holes of all or some of the water discharge hole rows may be selectively closed by the closing protrusions.

ノズル部材１３１の中央部には、絞り部材１２１の通水孔１２３の開口量を調節する水量調節手段としての水量調節体１４１が取り付けられる取付孔１３４が形成されている。この取付孔１３４は、厚さ方向に貫通した貫通孔であり、円筒部１３４ａが形成されていると共に、ノズル部材１３１の上面側に拡径部１３４ｂが形成されている。円筒部１３４ａと拡径部１３４ｂとの境界部には、縦方向の凹凸溝１３４ｃが周回方向に形成されており、水量調節体１４１の回転の滑り止めとなっている。   At the center of the nozzle member 131, a mounting hole 134 is formed in which a water amount adjusting body 141 as a water amount adjusting means for adjusting the opening amount of the water passage hole 123 of the throttle member 121 is attached. The attachment hole 134 is a through-hole penetrating in the thickness direction. A cylindrical portion 134 a is formed, and a diameter-expanded portion 134 b is formed on the upper surface side of the nozzle member 131. In the boundary portion between the cylindrical portion 134a and the enlarged diameter portion 134b, a vertical concavo-convex groove 134c is formed in the circumferential direction, and serves as an anti-slip of rotation of the water amount adjusting body 141.

［水量調節体の説明］
水量調節体１４１は、図７−図９及び図１４に示すように、流路が形成される流路形成部１４２とノズル部材１３１の取付孔１３４に挿嵌される嵌合部１４３とを有し、流路形成部１４２が嵌合部１４３に対して拡径する形状となっている。流路形成部１４２には、絞り部材１２１の通水孔１２３にある第一の孔部１２４に対応する第二の孔部１４４が複数形成されている。複数の第二の孔部１４４は、第一の孔部１２４の数に対応しており、同じ大きさの孔が等間隔に、ここでは四つ等間隔に四角形の頂部位置の配位で設けられている。第二の孔部１４４のそれぞれは、上面と側面を開口する略Ｌ字状の流路によって形成され、上面に、入口１４４ａが形成され、側面に、出口１４４ｂが形成されている。第二の孔部１４４は、この例に特に限定されるものではなく、例えば各孔部の水流が安定になるように構成されていれば、数や形状や大きさは特に限定されるものではない。 [Explanation of water volume regulator]
As shown in FIGS. 7 to 9 and 14, the water amount adjusting body 141 has a flow path forming portion 142 in which a flow path is formed and a fitting portion 143 to be inserted into the mounting hole 134 of the nozzle member 131. In addition, the flow path forming portion 142 has a shape that expands with respect to the fitting portion 143. A plurality of second hole portions 144 corresponding to the first hole portions 124 in the water passage holes 123 of the throttle member 121 are formed in the flow path forming portion 142. The plurality of second hole portions 144 correspond to the number of the first hole portions 124, and holes of the same size are provided at equal intervals, in this case, at four equal intervals and arranged at a square top position. It has been. Each of the second hole portions 144 is formed by a substantially L-shaped channel that opens on the upper surface and the side surface, and an inlet 144a is formed on the upper surface, and an outlet 144b is formed on the side surface. The second hole 144 is not particularly limited to this example. For example, the number, shape, and size of the second hole 144 are not particularly limited as long as the water flow in each hole is stabilized. Absent.

絞り部材１２１の第一の孔部１２４と水量調節体１４１の第二の孔部１４４の入口１４４ａとが最も重なっているときは、最も絞りが開いた状態であり、吐水量も最も大きくなる。そして、図１５（Ａ）、図１５（Ｂ）に示すように、第一の孔部１２４と第二の孔部１４４の入口１４４ａとの重なり度合いが小さくなると、その分、流路が狭くなり、吐水量が絞られることになる。図１５（Ｃ）は、第一の孔部１２４と第二の孔部１４４の入口１４４ａとが最もずれ、最も吐水量が絞られた状態となる。更に水量調節体１４１を絞り部材１２１に対して相対回転させると図１５（Ｄ）に示すように再び開口量が大きくなり図１５（Ｂ）と同等程度の開口量となり、回転に合わせて順次開口量が段階的に変化するように構成される。   When the first hole 124 of the throttle member 121 and the inlet 144a of the second hole 144 of the water amount adjusting body 141 are overlapped most, the throttle is in the most open state and the water discharge amount is also the largest. Then, as shown in FIGS. 15A and 15B, when the degree of overlap between the first hole 124 and the inlet 144a of the second hole 144 is reduced, the flow path is narrowed accordingly. The amount of water discharged will be reduced. In FIG. 15C, the first hole portion 124 and the inlet 144a of the second hole portion 144 are shifted most, and the amount of water discharged is most reduced. Further, when the water amount adjusting body 141 is rotated relative to the throttle member 121, the opening amount increases again as shown in FIG. 15D, and the opening amount is about the same as that in FIG. 15B. The quantity is configured to change stepwise.

流路形成部１４２の入口１４４ａが形成された上面は、中央部が最も低くなるように形成されており、水量調節体１４１の回転中心軸がズレたり振れたりしないように位置決めすると共に、絞り部材１２１の発条底部１２３ａによる外方に向かう付勢力によって水量調節体１４１を常時付勢し、流路形成部１４２とノズル部材１３１の中央に穿設される取付孔１３４における拡径部１３４ｂとの接触面の水密性を高めつつ、水量調節体１４１の意図しない回転を防止するように構成される。   The upper surface of the flow path forming portion 142 where the inlet 144a is formed is formed so that the central portion is the lowest, and is positioned so that the rotation center axis of the water amount adjusting body 141 does not shift or shake, and the throttle member The water amount adjusting body 141 is constantly urged by the outward urging force of the ridge bottom portion 123a of 121, and the contact between the flow path forming portion 142 and the enlarged diameter portion 134b in the mounting hole 134 drilled in the center of the nozzle member 131. The water amount adjuster 141 is configured to prevent unintentional rotation while enhancing the water tightness of the surface.

なお、第一及び第二の孔部１２４，１４４の数は、特に限定されるものではない。また、第一及び第二の孔部１２４，１４４は、二つ以上に分岐する流路を形成するように設けることが良く、更に好ましくは、上述のように四方向に等間隔に四角形の頂部位置の配位で設けるのが良い。また、第一及び第二の孔部１２４，１４４の形状は、円形に限定されるものではなく、菱形等の四角形やその他の多角形であっても良い。すなわち、第二の孔部１４４は、例えば各孔部の水流が安定になるように構成されていれば、数や形状や大きさは特に限定されるものではない。   In addition, the number of the 1st and 2nd hole parts 124 and 144 is not specifically limited. Further, the first and second holes 124 and 144 are preferably provided so as to form a flow path that branches into two or more, and more preferably, the tops of the squares are equally spaced in four directions as described above. It is good to provide it by position coordination. Further, the shape of the first and second holes 124 and 144 is not limited to a circle, and may be a quadrangle such as a rhombus or other polygons. That is, the number, shape, and size of the second hole 144 are not particularly limited as long as the water flow in each hole is stabilized, for example.

以上のような流路形成部１４２は、ノズル部材１３１の中央にある取付孔１３４における拡径部１３４ｂに嵌合され、これらの当接面の水密性が得られるように構成されることになる。流路形成部１４２に一体の嵌合部１４３は、ノズル部材１３１の中央にある取付孔１３４の円筒部１３４ａに嵌合される。嵌合部１４３は、その長さが取付孔１３４の吐水面１３１ａよりやや突出する長さに形成され、その先端面が手触りを良くするため円弧状面となっている。なお、先端面には、水量調節体１４１を回転するための「＋」や「−」のスクリュドライバの溝等を設けるようにしても良い。   The flow path forming part 142 as described above is configured to be fitted to the enlarged diameter part 134b in the mounting hole 134 in the center of the nozzle member 131, and to obtain water tightness of these contact surfaces. . The fitting part 143 integrated with the flow path forming part 142 is fitted into the cylindrical part 134 a of the mounting hole 134 in the center of the nozzle member 131. The fitting portion 143 is formed to have a length that slightly protrudes from the water discharge surface 131a of the mounting hole 134, and the tip end surface thereof is an arcuate surface to improve the touch. In addition, you may make it provide the groove | channel of the screw driver of "+" or "-" for rotating the water quantity adjustment body 141, etc. in the front end surface.

また、嵌合部１４３と流路形成部１４２との境界部分には、ノズル部材１３１の取付孔１３４の内周面に形成された凹凸溝１３４ｃに係合する凹凸部１４５が形成されている。凹凸部１４５は、凹凸溝１３４ｃと係合することで、水量調節体１４１の回転の滑り止めとなる。   Further, an uneven portion 145 that engages with an uneven groove 134 c formed on the inner peripheral surface of the attachment hole 134 of the nozzle member 131 is formed at the boundary portion between the fitting portion 143 and the flow path forming portion 142. The concavo-convex portion 145 is engaged with the concavo-convex groove 134 c to prevent the water amount adjusting body 141 from slipping.

水量調節体１４１は、嵌合部１４３を、ノズル部材１３１の取付孔１３４の円筒部１３４ａに嵌合し、流路形成部１４２を、拡径部１３４ｂに圧接させることによって、ノズル部材１３１の取付孔１３４に取り付けられる。すると、流路形成部１４２の上面とノズル部材１３１の第一の孔部１２４が形成された底面との間には、閉塞突起１２５が第一の係合凹部１３５又は第二の係合凹部１３６に突き当たることで空間部１４６が形成される。空間部１４６では、水量調節体１４１の第二の孔部１４４の出口１４４ｂから流出する水流が互いに衝合することで水圧を減圧する。水量調節体１４１は、取付孔１３４に取り付けられたとき、嵌合部１４３の先端部がノズル部材１３１の吐水面１３１ａより突出する。   The water amount adjusting body 141 is attached to the nozzle member 131 by fitting the fitting portion 143 into the cylindrical portion 134a of the attachment hole 134 of the nozzle member 131 and pressing the flow path forming portion 142 to the enlarged diameter portion 134b. It is attached to the hole 134. Then, between the upper surface of the flow path forming portion 142 and the bottom surface of the nozzle member 131 on which the first hole portion 124 is formed, the closing protrusion 125 is the first engaging recess 135 or the second engaging recess 136. The space portion 146 is formed by hitting. In the space part 146, the water flow flowing out from the outlet 144b of the second hole part 144 of the water amount adjusting body 141 collides with each other to reduce the water pressure. When the water amount adjusting body 141 is attached to the attachment hole 134, the distal end portion of the fitting portion 143 protrudes from the water discharge surface 131 a of the nozzle member 131.

図８及び図９に示すように、流量を調節するには、吐水面１３１ａより突出した嵌合部１４３の先端部を押圧し持ち上げることで凹凸溝１３４ｃと凹凸部１４５とが係合した状態を解除し、この解除した状態で、水量調節体１４１を回転することとなる。   As shown in FIGS. 8 and 9, in order to adjust the flow rate, the concave and convex grooves 134 c and the concave and convex portions 145 are engaged by pressing and lifting the tip of the fitting portion 143 protruding from the water discharge surface 131 a. The water amount adjusting body 141 is rotated in the released state.

［パッキンの説明］
パッキン１５１は、例えばゴムパッキンであり、図７−図９及び図１６に示すように、円筒部１５２と拡径部１５３とが中心軸線を一致させて一体に形成されている。拡径部１５３の湾曲面は、絞り部材１２１の外側の湾曲面の曲率及びノズル部材１３１の外周面の曲率に対応した球面状座面となっている。拡径部１５３の先端部は、ケーシング１１１に挿入された際、ケーシング１１１の吐水側開口部１１３の近傍に形成された段部１１４に係合する。また、円筒部１５２の先端部の外周面には、係合段部１５６が形成されている。この係合段部１５６は、例えば蛇口１０２の先端が係合される。かくして、パッキン１５１は、吐水側開口部１１３側に位置する先端部が段部１１４に係合し、係合段部１５６に蛇口１０２が係合圧接されることで、蛇口１０２とケーシング１１１との間の水漏れを防止する。 [Description of packing]
The packing 151 is, for example, a rubber packing, and as shown in FIGS. 7 to 9 and 16, the cylindrical portion 152 and the enlarged diameter portion 153 are integrally formed with the center axis line aligned. The curved surface of the enlarged diameter portion 153 is a spherical seating surface corresponding to the curvature of the curved surface outside the diaphragm member 121 and the curvature of the outer peripheral surface of the nozzle member 131. When inserted into the casing 111, the distal end portion of the enlarged diameter portion 153 engages with a stepped portion 114 formed in the vicinity of the water discharge side opening 113 of the casing 111. Further, an engagement step portion 156 is formed on the outer peripheral surface of the tip portion of the cylindrical portion 152. For example, the tip of the faucet 102 is engaged with the engagement step portion 156. Thus, the packing 151 has a tip portion located on the water discharge side opening 113 side engaged with the step portion 114, and the faucet 102 is engaged and pressed against the engagement step portion 156, whereby the faucet 102 and the casing 111 are connected. Prevent water leaks in between.

図７−図９に示すように、ノズル部材１３１に水量調節体１４１が取り付けられ、絞り部材１２１に組み付けられた組立体１５４は、略半球状をなし、拡径部１５３の球面座面を摺動し、ノズル部材１３１の吐水面１３１ａの角度を変更し得るように構成される。パッキン１５１の円筒部１５２と拡径部１５３とで構成される外側のコーナ部は、摺動する組立体１５４の突出部１２２、すなわち絞り部材１２１の突出部１２２が係合し、可動範囲を規制する規制部１５５となる。   As shown in FIGS. 7 to 9, the water amount adjusting body 141 is attached to the nozzle member 131, and the assembly 154 assembled to the throttle member 121 has a substantially hemispherical shape and slides on the spherical bearing surface of the enlarged diameter portion 153. It moves, and it is comprised so that the angle of the water discharge surface 131a of the nozzle member 131 can be changed. The outer corner portion composed of the cylindrical portion 152 and the enlarged diameter portion 153 of the packing 151 is engaged with the protruding portion 122 of the sliding assembly 154, that is, the protruding portion 122 of the throttle member 121, and the movable range is restricted. It becomes the regulation part 155 to do.

［節水器具の組立］
以上のように構成された節水器具１０１は、次のように組み立てられる。先ず、ノズル部材１３１の取付孔１３４には、図１５に示すように、絞り部材１２１の第一の孔部１２４と水量調節体１４１の第二の孔部１４４の入口１４４ａとの重なり度合いを調節して、水量調節体１４１が取り付けられる。次いで、ノズル部材１３１は、絞り部材１２１が組み合わされ、組立体１５４とされる。 [Assembly of water-saving equipment]
The water-saving device 101 configured as described above is assembled as follows. First, as shown in FIG. 15, the degree of overlap between the first hole 124 of the throttle member 121 and the inlet 144 a of the second hole 144 of the water amount adjusting body 141 is adjusted in the mounting hole 134 of the nozzle member 131. Then, the water amount adjusting body 141 is attached. Next, the nozzle member 131 is combined with the throttle member 121 to form an assembly 154.

この組立体１５４は、パッキン１５１に組み合わされる。具体的に、パッキン１５１の円筒部１５２に、絞り部材１２１の突出部１２２を臨ませるようにして、パッキン１５１の拡径部１５３内に組み合わされる。この後、組立体１５４が組み合わされたパッキン１５１は、ケーシング１１１内に配設される。具体的に、パッキン１５１は、吐水側開口部１１３側に位置する先端部が段部１１４に係合される。   This assembly 154 is combined with the packing 151. Specifically, the cylindrical portion 152 of the packing 151 is combined with the expanded portion 153 of the packing 151 such that the protruding portion 122 of the throttle member 121 faces the cylindrical portion 152. Thereafter, the packing 151 combined with the assembly 154 is disposed in the casing 111. Specifically, the packing 151 is engaged with the stepped portion 114 at the distal end located on the water discharge side opening 113 side.

この後、ケーシング１１１は、取付開口部１１２の内周面にあるねじ溝１１２ａを蛇口１０２のねじ部に締め付けることによって、ケーシング１１１が蛇口１０２等に取り付けられる。パッキン１５１は、係合段部１５６に蛇口１０２が係合圧接されることで、蛇口１０２とケーシング１１１との間の水漏れを防止することができる。   Thereafter, the casing 111 is attached to the faucet 102 or the like by tightening the thread groove 112 a on the inner peripheral surface of the attachment opening 112 to the screw portion of the faucet 102. The packing 151 can prevent water leakage between the faucet 102 and the casing 111 when the faucet 102 is engaged and pressed against the engaging step portion 156.

［節水器具の動作］
以上のような節水器具１０１は、蛇口１０２の給水口１０３から水が供給されると、水が絞り部材１２１の通水孔１２３より第一の孔部１２４と水量調節体１４１の第二の孔部１４４を通って絞り部材１２１とノズル部材１３１との間の空間部１４６に供給される。空間部１４６には、絞り部材１２１等で吐水量が絞られて供給されることになる。そして、水流は、第二の孔部１４４で水流の方向が曲げられ、また、空間部１４６で、第二の孔部１４４の出口１４４ｂから流出する水流が互いに衝合することで、水圧が減圧される。この後、減圧された水は、ノズル部材１３１の吐水孔１３２から吐水される。 [Operation of water-saving equipment]
In the water-saving device 101 as described above, when water is supplied from the water supply port 103 of the faucet 102, the water is supplied through the first hole 124 and the second hole of the water amount adjusting body 141 from the water passage hole 123 of the throttle member 121. It is supplied to the space portion 146 between the throttle member 121 and the nozzle member 131 through the portion 144. The space 146 is supplied with the amount of water discharged by the throttle member 121 or the like. The direction of the water flow is bent at the second hole 144, and the water flow flowing out from the outlet 144b of the second hole 144 collides with each other at the space 146, so that the water pressure is reduced. Is done. Thereafter, the decompressed water is discharged from the water discharge hole 132 of the nozzle member 131.

・吐水方向の調節
以上のような節水器具１０１では、図８及び図９に示すように、ノズル部材１３１を絞り部材１２１に組み合わせてなる組立体１５４は、上半球に下半球の一部を足した完全なる半球体よりやや大きいものとなる。すなわち、この組立体１５４は、この組立体１５４を含む球体の最大直径Ｒ１を含む半球体となり、吐水面１３１ａの直径Ｒ２が最大直径Ｒ１よりやや小さくなる形状となっている。そして、組立体１５４は、絞り部材１２１の外面とノズル部材１３１の外面とで連続的な略半球面状の外表面を構成する。 Adjustment of water discharge direction In the water-saving device 101 as described above, as shown in FIGS. 8 and 9, the assembly 154 formed by combining the nozzle member 131 with the throttle member 121 has a portion of the lower hemisphere attached to the upper hemisphere. A little larger than a perfect hemisphere. That is, the assembly 154 is a hemisphere including the maximum diameter R1 of the sphere including the assembly 154, and the diameter R2 of the water discharge surface 131a is slightly smaller than the maximum diameter R1. In the assembly 154, the outer surface of the throttle member 121 and the outer surface of the nozzle member 131 constitute a continuous substantially hemispherical outer surface.

パッキン１５１の拡径部１５３を構成する球面とケーシング１１１の吐水側開口部１１３近傍の球面支持部１１３ａとは、組立体１５４の外表面がなす略半球面に対応した連続的な球面をなし、組立体１５４の転動に伴う摺動を許容する球面座面となっている。   The spherical surface constituting the diameter-enlarged portion 153 of the packing 151 and the spherical surface support portion 113a in the vicinity of the water discharge side opening 113 of the casing 111 form a continuous spherical surface corresponding to the substantially hemispherical surface formed by the outer surface of the assembly 154. It is a spherical bearing surface that allows sliding along with the rolling of the assembly 154.

なお、本発明では、少なくともパッキン１５１の拡径部１５３が球面座面となっていれば、組立体１５４は転動可能であるから、ケーシング１１１の球面支持部１１３ａは必ずしも球面座面となっていなくても良い。   In the present invention, since the assembly 154 can roll if at least the diameter-enlarged portion 153 of the packing 151 is a spherical seat surface, the spherical support portion 113a of the casing 111 is not necessarily a spherical seat surface. It is not necessary.

更に、球面支持部１１３ａの直径Ｒ３は、組立体１５４の最大直径Ｒ１より小さくなっており、組立体１５４がケーシング１１１より脱落しないようになっている。   Furthermore, the diameter R3 of the spherical support portion 113a is smaller than the maximum diameter R1 of the assembly 154, so that the assembly 154 does not fall off the casing 111.

したがって、組立体１５４は、例えば、吐水面１３１ａを指等で偏圧的に押圧することによって、絞り部材１２１の突出部１２２がパッキン１５１の規制部１５５に突き当たるまでの範囲内で、自在に傾けることができる。また、吐水中にあっては、パッキン１５１の内側の空間において発生する内圧によって、絞り部材１２１やノズル部材１３１がパッキン１５１に圧接されることになる。したがって、吐水面１３１ａの調節した傾きが使用中にずれてしまうこともない。   Therefore, for example, the assembly 154 can be freely tilted within a range until the protruding portion 122 of the throttle member 121 hits the restricting portion 155 of the packing 151 by pressing the water discharge surface 131a with a finger or the like. be able to. Further, when the water is being discharged, the throttle member 121 and the nozzle member 131 are pressed against the packing 151 by the internal pressure generated in the space inside the packing 151. Therefore, the adjusted inclination of the water discharge surface 131a does not shift during use.

図１７（Ａ）及び図１８（Ａ）は、吐水面１３１ａの傾きを０°として、吐水方向を鉛直にした状態を示している。また、図１７（Ｂ）及び図１８（Ｂ）は、吐水面１３１ａを一方に最大限傾けた状態を示している。この状態では、組立体１５４を構成する絞り部材１２１の突出部１２２がパッキン１５１の規制部１５５に突き当たり、これ以上吐水面１３１ａが傾かないようになっている。更に、図１７（Ｃ）及び図１８（Ｃ）は、吐水面１３１ａを他方に最大限傾けた状態を示している。この状態でも、組立体１５４を構成する絞り部材１２１の突出部１２２がパッキン１５１の規制部１５５に突き当たり、これ以上吐水面１３１ａが傾かないようになっている。   FIG. 17A and FIG. 18A show a state in which the water discharge direction is vertical with the inclination of the water discharge surface 131a set to 0 °. FIGS. 17B and 18B show a state in which the water discharge surface 131a is tilted to the maximum. In this state, the protruding portion 122 of the throttle member 121 constituting the assembly 154 hits the restricting portion 155 of the packing 151 so that the water discharge surface 131a does not tilt any further. Further, FIG. 17C and FIG. 18C show a state in which the water discharge surface 131a is tilted to the maximum extent. Even in this state, the protruding portion 122 of the throttle member 121 constituting the assembly 154 abuts against the restricting portion 155 of the packing 151 so that the water discharge surface 131a does not tilt any further.

なお、この吐水方向の調節を行うに当たっては、上述した水量調節体１４１は必ずしも設ける必要はない。水量調節体１４１を設けない場合には、ノズル部材１３１の取付孔１３４を設けなければよい。また、組立体１５４は、完全な半球体であっても良い。   It should be noted that the water amount adjusting body 141 described above is not necessarily provided when adjusting the water discharge direction. If the water amount adjusting body 141 is not provided, the attachment hole 134 of the nozzle member 131 may not be provided. The assembly 154 may be a complete hemisphere.

・第一の水量調節
節水器具１０１では、ノズル部材１３１を絞り部材１２１に対して回転させることで、節水の程度を調節することができる。具体的に、この節水器具１０１において、外周吐水孔列１３２ａからは、常時吐水され、吐水される水流が常に太く見えるようにしている。これに対して、内周吐水孔列１３２ｂでは、絞り部材１２１の閉塞突起１２５によって、ノズル部材１３１の吐水孔１３２が選択的に閉塞される。具体的に、図１３（Ａ）及び図１７（Ａ）−（Ｃ）に示すように、閉塞突起１２５が吐水孔１３２と連続した第一の係合凹部１３５に係合しているときには、吐水孔１３２は閉塞され、内周吐水孔列１３２ｂからは吐水されない状態となる（節水位置）。一方、図１３（Ｂ）及び図１８（Ａ）−（Ｃ）に示すように、閉塞突起１２５が吐水孔１３２，１３２の間の第二の係合凹部１３６に係合しているときには、吐水孔１３２は開放され、内周吐水孔列１３２ｂからも吐水される状態となる（準節水位置）。すなわち、ノズル部材１３１が準節水位置にあるとき、吐水面１３１ａからの流線は、二重となり、節水位置にあるとき、流線は一重となる。 -First water amount adjustment In the water-saving device 101, the degree of water saving can be adjusted by rotating the nozzle member 131 relative to the throttle member 121. Specifically, in this water-saving device 101, water is constantly discharged from the outer peripheral water discharge hole row 132a so that the discharged water flow always looks thick. On the other hand, in the inner peripheral water discharge hole row 132b, the water discharge holes 132 of the nozzle member 131 are selectively closed by the closing protrusions 125 of the throttle member 121. Specifically, as shown in FIGS. 13 (A) and 17 (A)-(C), when the closing protrusion 125 is engaged with the first engagement recess 135 continuous with the water discharge hole 132, the water discharge The holes 132 are closed, and water is not discharged from the inner circumferential water discharge hole row 132b (water saving position). On the other hand, as shown in FIGS. 13B and 18A to 18C, when the closing projection 125 is engaged with the second engagement recess 136 between the water discharge holes 132, 132, the water discharge The holes 132 are opened, and water is discharged from the inner circumferential water discharge hole row 132b (quasi-water-saving position). That is, when the nozzle member 131 is in the quasi-water-saving position, the streamline from the water discharge surface 131a is double, and when it is in the water-saving position, the streamline is single.

節水器具１０１では、常に、ノズル部材１３１が節水位置にあるとき、外周吐水孔列１３２ａから吐水され、その内側で内周吐水孔列１３２ｂから吐水されないようになっている。したがって、節水器具１０１では、内周吐水孔列１３２ｂから吐水されず吐水量が減ったことを見た目で分からないようにしながら節水を行うことができる。   In the water-saving device 101, when the nozzle member 131 is always in the water-saving position, water is discharged from the outer peripheral water discharge hole row 132a, and water is not discharged from the inner peripheral water discharge hole row 132b inside thereof. Therefore, in the water-saving device 101, it is possible to perform water-saving while making it apparent that the amount of water discharged has not been discharged from the inner peripheral water discharge hole row 132b and the amount of water discharged has decreased.

このノズル部材１３１の回転操作の方法は特に限定されるものではなく、節水器具１０１が分解された状態において、絞り部材１２１に対してノズル部材１３１を回転させても良い他、分解するまでもなく、組立後の状態において、指や治具を使って、ケーシング１１１の吐水側開口部１１３より臨むノズル部材１３１を回転させても良い。更に、ノズル部材１３１に、ケーシング１１１より外部に臨む操作突起を設けて、この操作突起を用いてノズル部材１３１を回転させても良い。また、絞り部材１２１、ノズル部材１３１の何れか一方に、突起を設け、他方に、突起が選択的に係合される凹部を複数設け、絞り部材１２１とノズル部材１３１とが相対回転することで、突起が凹部に選択的に係合するようにして、絞り部材１２１とノズル部材１３１の相対的位置を一定に保持するようにしても良い。更に、ケーシング１１１を開口部を設けて、何れの凹部に突起部が係合されているのかを目視できるようにし、設定状態を目視で確認できるようにしても良い。   The method for rotating the nozzle member 131 is not particularly limited, and the nozzle member 131 may be rotated with respect to the throttle member 121 in a state where the water-saving device 101 is disassembled, and it is not necessary to disassemble it. In a state after assembly, the nozzle member 131 facing the water discharge side opening 113 of the casing 111 may be rotated using a finger or a jig. Furthermore, the nozzle member 131 may be provided with an operation projection facing the outside from the casing 111, and the nozzle member 131 may be rotated using the operation projection. Further, either one of the diaphragm member 121 and the nozzle member 131 is provided with a protrusion, and the other is provided with a plurality of recesses to which the protrusion is selectively engaged, so that the diaphragm member 121 and the nozzle member 131 rotate relative to each other. The relative positions of the throttle member 121 and the nozzle member 131 may be kept constant by selectively engaging the protrusions with the recesses. Further, the casing 111 may be provided with an opening so that it can be visually confirmed which concave portion is engaged with the protrusion, and the set state can be visually confirmed.

なお、この節水調節を行うに当たっては、上述した水量調節体１４１は必ずしも設ける必要はない。水量調節体１４１を設けない場合には、上述のように、ノズル部材１３１の取付孔１３４を設けなければよい。   In addition, in performing this water-saving adjustment, the water amount adjusting body 141 described above is not necessarily provided. When the water amount adjusting body 141 is not provided, the attachment hole 134 of the nozzle member 131 may not be provided as described above.

・第二の水量調節
節水器具１０１では、水量調節体１４１を回転することによって、吐水量を調節することができる。絞り部材１２１の第一の孔部１２４と水量調節体１４１の第二の孔部１４４の入口１４４ａとが最も重なっているときは、最も絞りが開いた状態であり、吐水量も最も多くなる。そして、図１５（Ａ）、図１５（Ｂ）に示すように、第一の孔部１２４と第二の孔部１４４の入口１４４ａとの重なり度合いが小さくなると、その分、流路が小さくなり、吐水量が絞られることになる。図１５（Ｃ）は、第一の孔部１２４と第二の孔部１４４の入口１４４ａとが最もずれ、最も吐水量が絞られた状態となる。更に水量調節体１４１を絞り部材１２１に対して相対回転させると図１５（Ｄ）に示すように再び開口量が大きくなり図１５（Ｂ）と同等程度の開口量となり、回転に合わせて順次開口量が段階的乃至連続的に変化するようになっている。 -Second water amount adjustment In the water-saving device 101, the water discharge amount can be adjusted by rotating the water amount adjusting body 141. When the first hole 124 of the throttle member 121 and the inlet 144a of the second hole 144 of the water amount adjusting body 141 are overlapped most, the throttle is in the most open state, and the amount of water discharged is the largest. As shown in FIGS. 15A and 15B, when the degree of overlap between the first hole 124 and the inlet 144a of the second hole 144 is reduced, the flow path is reduced accordingly. The amount of water discharged will be reduced. In FIG. 15C, the first hole portion 124 and the inlet 144a of the second hole portion 144 are shifted most, and the amount of water discharged is most reduced. Further, when the water amount adjusting body 141 is rotated relative to the throttle member 121, the opening amount increases again as shown in FIG. 15D, and the opening amount is about the same as that in FIG. 15B. The amount is changed stepwise or continuously.

この水量調節は、例えば、節水器具１０１が組み立てられた状態において、吐水面１３１ａより突出した嵌合部１４３の先端部を押圧し持ち上げることで凹凸溝１３４ｃと凹凸部１４５とが係合した状態を解除乃至弱めて解放し、この解放した状態で、水量調節体１４１を回転させることによってなされる。   For example, in the state in which the water-saving device 101 is assembled, the water amount adjustment is performed by pressing and lifting the distal end portion of the fitting portion 143 protruding from the water discharge surface 131a so that the uneven groove 134c and the uneven portion 145 are engaged. Release or weaken and release, and in this released state, the water amount adjusting body 141 is rotated.

［節水器具の効果］
以上のような節水器具１０１によれば、ケーシング１１１内に、絞り部材１２１とノズル部材１３１が設けられることで、吐水量を絞り節水することができる。具体的に、絞り部材によって絞られた水流が、更にノズル部材１３１によって適度な吐水量と水勢に調節されて吐出孔列１３２ａ，１３２ｂから吐水されるので、使用感の良好な節水を行うことができる。更に、水量調節体１４１によって、外部からの簡単な操作で吐出孔列１３２ａ，１３２ｂに供給される吐水量を調節することもでき、これにより、水圧や吐水量の微調整を行うことが可能となる。 [Effect of water-saving equipment]
According to the water-saving device 101 as described above, the throttle member 121 and the nozzle member 131 are provided in the casing 111, so that the amount of water discharged can be reduced. Specifically, the water flow squeezed by the squeezing member is further adjusted to an appropriate water discharge amount and water force by the nozzle member 131 and discharged from the discharge hole arrays 132a and 132b. it can. Furthermore, the amount of discharged water supplied to the discharge hole arrays 132a and 132b can be adjusted by a simple operation from the outside by the water amount adjusting body 141, which makes it possible to finely adjust the water pressure and the amount of discharged water. Become.

加えて、絞り部材１２１とノズル部材１３１との組立体１５４は、パッキン１５１内に摺動可能に取り付けられ、吐水面１３１ａの角度を可変とする。したがって、外部からの簡単な操作で水の吐出方向を容易に調節することができる。これによって、節水を行いながら、水圧を上げたときにも、吐出方向を調節することで、水滴が洗面器の外にまで飛散して、洗面器の周囲が汚損することを防止できる。すなわち、節水器具１０１では、吐水や水滴が洗面器の外にまで飛散しない範囲で、使い勝手が良いように、吐水量や吐出方向を容易に微調節することができる。   In addition, an assembly 154 of the throttle member 121 and the nozzle member 131 is slidably mounted in the packing 151, and the angle of the water discharge surface 131a is variable. Therefore, the water discharge direction can be easily adjusted by a simple operation from the outside. Thus, even when the water pressure is increased while water is being saved, by adjusting the discharge direction, it is possible to prevent water droplets from splashing out of the washbasin and surrounding the washbasin. That is, in the water-saving device 101, the amount of water discharged and the direction of discharge can be easily fine-tuned so as to be easy to use within a range in which water discharge and water droplets do not scatter to the outside of the washbasin.
