Description

この発明は、水栓からの吐水流量を調整することによって節水効果を得ることのできる節水具及び節水装置に関する。特に、ハンドルコック式の水栓だけでなくシングルレバー式の水栓にも共用することができ、かつ吐水流量を簡単に調整することが可能な節水具及び節水装置に関する。   The present invention relates to a water-saving device and a water-saving device that can obtain a water-saving effect by adjusting the flow rate of water discharged from a faucet. In particular, the present invention relates to a water-saving device and a water-saving device that can be used not only for handle cock-type faucets but also for single lever-type faucets and that can easily adjust the water discharge flow rate.

一般家庭やレストランあるいはホテル等における調理場、洗面所、浴室等において調理や洗浄や入浴などのために水やお湯を使用する際、使用者は手動式の回転可能なハンドルコックを操作することによって単水栓や湯水混合栓等の自在水栓から流れ出る水やお湯などの吐水流量(吐出量)を調整することができるようになっている。すなわち、使用者によるハンドルコックの回転量に応じて前記水栓の弁開度が変わり、それに従い水栓から流れ出る水やお湯などの吐水流量が変化する。また、浴室などに設備されるシャワーにおいても、湯水混合栓から分岐したホースの根元に設けられたハンドルコックの操作によって吐水流量を調整できるようになっているのが一般的である。このようなハンドルコック式の水栓やシャワー設備では、従来から節水を図るために当該水栓出口とスパウト内との結合部や、ホースとシャワーヘッドとの結合部などに節水具を組み込むことが行われている。こうした節水具としては、例えば下記に示す特許文献1、2に開示されている節水具(節水コマ)などが従来から知られている。下記公報に記載の節水具やその他の従来知られた節水具においては、水栓本体やシャワーヘッドの内部流量を節水具内部に設けた孔で絞ることにより、水栓の弁開度にほぼ比例する吐水流量を前記孔の大きさにより調整して節水を行うようにしている。

When using water or hot water for cooking, washing, bathing, etc. in a kitchen, washroom, bathroom, etc. in a general home, restaurant, hotel, etc., the user must operate a manual rotatable handle cock. It is possible to adjust the water discharge flow rate (discharge amount) of water and hot water flowing out from a free faucet such as a single faucet or a hot water / water mixing tap. That is, the valve opening degree of the faucet changes according to the amount of rotation of the handle cock by the user, and the flow rate of water discharged from the faucet or hot water changes accordingly. Also, in a shower installed in a bathroom or the like, it is general that the water discharge flow rate can be adjusted by operating a handle cock provided at the base of a hose branched from a hot and cold water mixing tap. In such a handle cock-type faucet or shower facility, in order to save water, a water-saving device has been incorporated in the joint between the faucet outlet and the spout or the joint between the hose and the shower head. Has been done. As such water-saving tools, for example, water-saving tools (water-saving tops) disclosed in Patent Documents 1 and 2 shown below have been conventionally known. In the water-saving device described in the following publication and other conventionally known water-saving devices, the internal flow rate of the faucet body and shower head is throttled by a hole provided in the water-saving device, which is almost proportional to the valve opening of the water faucet. The water discharge is adjusted by the size of the hole to save water.
Japanese Utility Model Publication No.59-158794 Japanese Utility Model Publication No. 60-21089

ところで、最近では一般家庭やレストランあるいはホテルなどにおいて、レバーの上下動に応じて水栓の弁開度を変えることのできる、つまり使用者がレバーを上げ下げするだけで水栓からの吐水流量を変えることのできるようにした所謂シングルレバー式(又はワンタッチレバー式とも呼ぶ)の水栓が普及してきている。こうしたシングルレバー式の水栓においては、僅かなレバー操作が行われただけで急激に吐水流量が変化してしまう。そのため、使用者が必要とする水量に調節するためにはレバーの微調整を行わなければならずこうした操作は面倒であること、特に幼児や高齢者等の使用者にとってはこうしたレバー操作が非常に難しいこと、などからついつい水を出し過ぎた状態のままで使用してしまうことが多い。そこで、シングルレバー式の水栓においてはこうした水の出し過ぎを防止するために予め元栓を絞っておくという方法が考えられるが、こうした方法を採用すると使用者の使用感が失われるだけでなく、建物全体における水圧が落ちてしまい建物の至る場所で水の出が悪くなってしまうことが生じることから、こうした方法は実用的とは言えず採用できないものである。そこで、シングルレバー式の水栓に適した節水具が望まれるが、上述したような従来知られた節水具は水栓出口とその先のスパウトとの結合部に節水具を組み込む形式のものであったため、シングルレバー式の水栓にそれらの節水具をそのまま適用することはできなかった。すなわち、仮に従来公知の節水具を単純にシングルレバー式水栓の出口に組み込めるような何らかの構造を工夫したとしても、それだけでは単に水量を調整できるだけにすぎず、日常的に使い易い、滑らかな吐出流を生じさせるものとはならない。このように、シングルレバー式の水栓に適した節水具は従来なかったために、シングルレバー式の水栓に対して節水を施すことは非常に難しい、という問題点があった。同様の問題点はシングルレバー式水栓に限らず、水流吐出口に節水具を設けるタイプのすべての節水具において存在する。
また、従来においては、節水具内部に設けた孔の大きさがそれぞれ異なる多種類の節水具を予め用意しておき、必要とされる吐水流量にあった大きさの孔が設けられている節水具をその都度交換しながら取り付ける必要があった。しかし、吐水流量に応じて孔の大きさの異なる多種類の節水具を予め用意しておくことはコストが高くなってしまい都合が悪い。さらに、単に孔の大きさの異なる節水具を交換することだけでは、感覚的に異なりうる個々のユーザ毎の使用感を満足させる吐水流量への微妙な調整が非常に難しかった。
By the way, recently, in general households, restaurants or hotels, the valve opening of the faucet can be changed according to the vertical movement of the lever, that is, the flow rate of water discharged from the faucet can be changed simply by the user raising and lowering the lever. A so-called single lever type (or one-touch lever type) faucet that can be used has become widespread. In such a single lever-type faucet, the water discharge flow rate changes abruptly only by a slight lever operation. Therefore, in order to adjust the amount of water required by the user, it is necessary to make fine adjustments to the lever, which is troublesome, especially for users such as infants and the elderly. In many cases, it is used in a state where water has been excessively discharged due to difficult things. Therefore, in the single lever type faucet, it is conceivable to squeeze the main stopper in advance in order to prevent excessive discharge of water, but if such a method is adopted, not only the user's feeling of use is lost, Such a method is not practical and cannot be adopted because the water pressure in the entire building drops and the water outflows everywhere in the building. Therefore, a water-saving device suitable for a single lever-type faucet is desired. However, the conventional water-saving device as described above is a type in which a water-saving device is incorporated at the joint between the faucet outlet and the spout. Therefore, those water-saving devices could not be applied to single-lever faucets. In other words, even if a conventional water-saving device can be devised simply by incorporating it into the outlet of a single-lever faucet, it can only adjust the amount of water, and it is easy to use on a daily basis. It does not cause a flow. As described above, since there has been no water-saving device suitable for a single lever-type faucet, there has been a problem that it is very difficult to save water on a single-lever-type faucet. The same problem exists not only in the single lever type faucet but also in all the water saving tools of the type in which a water saving tool is provided at the water flow outlet.
In addition, conventionally, various types of water-saving devices having different sizes of holes provided in the water-saving device are prepared in advance, and the water-saving water is provided with holes of a size suitable for the required water discharge flow rate. It was necessary to replace the tool every time it was replaced. However, it is inconvenient to prepare various kinds of water-saving tools having different hole sizes according to the water discharge flow rate because the cost increases. Furthermore, it is very difficult to finely adjust the water discharge flow rate that satisfies the feeling of use for each individual user, which can be different sensibly, simply by replacing water saving devices having different hole sizes.

本発明は上述の点に鑑みてなされたもので、シングルレバー式水栓などの水流出口に装着するのに適した節水装置を提供しようとするものである。 This invention is made | formed in view of the above-mentioned point, and intends to provide the water-saving apparatus suitable for mounting | wearing with water outlets, such as a single lever type faucet.

The flow rate adjusting plate 4 can be detachably mounted on the water flow adjusting portion 2 by the mounting member N, and is formed in a shape that substantially fits the shape inside the cylindrical portion 1c. Is done. The attachment member N is a kind of screw having a shaft portion formed in a screw shape, and a groove for fitting an attachment device such as a driver is formed in the head portion. When the mounting member N is rotated by the mounting tool fitted in the head portion, the shaft portion of the mounting member N passes through the central hole 4a of the flow rate adjusting plate 4 and enters the central hole 2a of the water flow adjusting unit 2, and the flow rate The adjusting plate 4 can be fixed on the water flow adjusting unit 2. For example, a male screw is cut on the outer periphery of the shaft portion of the mounting member N, and a female screw is cut on the inner periphery of the central hole 2a of the adjusting portion 2, and the head portion and the water flow are adjusted by tightening the mounting member N around the screw. The flow rate adjusting plate 4 is sandwiched between the portion 2 and fixed. In addition to the central holes 2a and 4a, one or a plurality of water passage holes 2b and 4b are formed in the adjusting unit 2 and the flow rate adjusting plate 4 with appropriate shapes, numbers, arrangements and dimensions, respectively. Here, as an example, each of the water holes 2b and 4b is shown as having four circular holes. However, the shape is not limited to a circle and may be an appropriate shape and number, and the opening area and arrangement thereof will be described later. As will be explained, it is designed and adjusted as appropriate so as to obtain a desired water saving amount and reduced pressure or buffer action. Further, for example, the four water holes 4b of the water flow adjusting unit 4 are completely separated in the illustrated example, but as shown in FIG. 2, the two water holes 4b are connected to each other. There may be.

なお、一般的には、ステンレスあるいは真鍮などの耐腐食性金属素材を切削加工することで、所望の構造/形状の円筒部1cと調整部2(さらにはフランジ3)を一体的に具備する節水具1の本体を製造するのがよいが、これに限らず、適宜の素材及び製造法により節水具1の本体を製造してよい。
なお、流量調整板4を水流調整部2の下側に着脱可能に装着することのできるように構成してもよいことは言うまでもない。
In general, by cutting a corrosion-resistant metal material such as stainless steel or brass, a water-saving system that integrally includes the cylindrical portion 1c and the adjusting portion 2 (and the flange 3) having a desired structure / shape. Although the main body of the tool 1 is good to manufacture, it is not restricted to this, You may manufacture the main body of the water-saving tool 1 with an appropriate raw material and manufacturing method.
In addition, it cannot be overemphasized that you may comprise so that the flow volume adjustment board 4 can be attached to the lower side of the water flow adjustment part 2 so that attachment or detachment is possible.

円筒部1c内に形成された通水孔(開口)付きの水流調整部2と、該水流調整部2上に載置された同じく通水孔(開口)付きの流量調整板4は、水流量を絞る(節水)作用をもたらすのみならず、水流が調整部2及び流量調整板4の開口以外の個所(障害物)に当たることによる緩衝作用による水流の調整を図ることができる。すなわち、各通水孔の重ね合わせの状態を変えることに応じて、水流量の絞り込みによる流量の調整を図ることができる。具体的な作用は、調整部2及び流量調整板4に設ける各通水孔2b,4bの形状及び個数、開口面積及び配置等、あるいは水流の向きによって異なり得る。   A water flow adjusting part 2 with a water flow hole (opening) formed in the cylindrical part 1c and a flow rate adjusting plate 4 with a water flow hole (opening) placed on the water flow adjusting part 2 are The water flow can be adjusted by a buffering action when the water flow hits a portion (obstacle) other than the opening of the adjusting unit 2 and the flow rate adjusting plate 4. That is, it is possible to adjust the flow rate by narrowing the water flow rate according to changing the overlapping state of the water flow holes. The specific action may vary depending on the shape and number of the water passage holes 2b, 4b provided in the adjusting unit 2 and the flow rate adjusting plate 4, the opening area and the arrangement, or the direction of the water flow.

まず、図1(a)に示すように、フランジ3とは反対側の端部1aを水流入口とし、フランジ3側の端部1bを水流出口とし、水流の向きが矢印X方向である場合について説明する。端部1a寄りに配置される流量調整板4及び端部1b寄りの水流調整部2には、それぞれ同じ形状,個数,配置の4つの通水孔2a,4aがそれぞれ形成されている。流量調整板4は取付部材Nにより水流調整部2上に載置されていることから、取付部材Nによる締め付けをゆるめて該流量調整板4を水流調整部2上で回転させると、該回転量に応じた分だけ流量調整板4の通水孔4bの位置と調整部2の通水孔2bとの相対的な位置が変わり、調整部2に設けた通水孔2bの実質的な開口面積が変化することになる。この開口面積の大小(つまり、前記流量調整板4と調整部2の通水孔2bとの間に形成される流路の大きさ)によって水流の絞り込み量が決まり、流量調整が行われる。また、流量調整板4に設けた複数の通水孔4bと調整部2に設けた通水孔2bとの相対的な位置が変化すると、水流が開口部以外の個所(障害物)に当たる面積も変わることから、これにより生ずる干渉/緩衝作用による水流の調整を行うこともできる。なお、最終的な節水量(絞り量)は、上記のように調整部2と流量調整板4とが重ね合わされたときの調整部2の通水孔2bの開口面積の大小によって決まるので、所望の節水量(絞り量)が得られるように調整部2及び流量調整板4の通水孔2b,4bのサイズを設計・加工時において適宜調整すればよい。また、調整部2及び流量調整板4の通水孔2b,4bは厚さを考慮して調整するとよい。すなわち、絞り量を相対的に大きくすると、水の勢いが相対的に減ぜられて、使用者の使用感を損なうことがあり得る。そこで、絞り孔の厚さを増すとそれに応じて水の勢いが増すことが知られているので、調整部2及び流量調整板4の通水孔2b,4bの厚さ(つまり調整部2,流量調整板4の厚さ)を適宜の厚み加減に調整することによって、使用者の使用感を損なわないように、調整水流に勢いをつけることができる。   First, as shown in FIG. 1 (a), the end 1a on the opposite side of the flange 3 is a water inlet, the end 1b on the flange 3 side is a water outlet, and the direction of the water flow is in the direction of the arrow X. explain. Four flow holes 2a and 4a having the same shape, number and arrangement are respectively formed in the flow rate adjusting plate 4 arranged near the end 1a and the water flow adjusting unit 2 near the end 1b. Since the flow rate adjusting plate 4 is mounted on the water flow adjusting unit 2 by the mounting member N, when the flow rate adjusting plate 4 is rotated on the water flow adjusting unit 2 by loosening the tightening by the mounting member N, the rotation amount The position of the water flow hole 4b of the flow rate adjustment plate 4 and the relative position of the water flow hole 2b of the adjustment unit 2 are changed by an amount corresponding to the actual flow area of the water flow hole 2b provided in the adjustment unit 2. Will change. The amount of narrowing the water flow is determined by the size of the opening area (that is, the size of the flow path formed between the flow rate adjusting plate 4 and the water flow hole 2b of the adjusting unit 2), and the flow rate is adjusted. Moreover, when the relative position of the water flow holes 4b provided in the flow rate adjusting plate 4 and the water flow holes 2b provided in the adjustment unit 2 changes, the area where the water flow hits a place (obstacle) other than the opening is also obtained. As a result, the water flow can be adjusted by the interference / buffer action caused by this. Note that the final water saving amount (throttle amount) is determined by the size of the opening area of the water passage hole 2b of the adjusting unit 2 when the adjusting unit 2 and the flow rate adjusting plate 4 are overlapped as described above. The size of the water flow holes 2b and 4b of the adjusting unit 2 and the flow rate adjusting plate 4 may be adjusted as appropriate during the design and processing so that the water saving amount (throttle amount) can be obtained. Moreover, it is good to adjust the water flow holes 2b and 4b of the adjustment part 2 and the flow volume adjustment board 4 in consideration of thickness. That is, if the amount of squeezing is relatively large, the momentum of water is relatively reduced, and the user's feeling of use may be impaired. Therefore, it is known that increasing the thickness of the throttle hole increases the water momentum accordingly, so the thickness of the water flow holes 2b, 4b of the adjusting unit 2 and the flow rate adjusting plate 4 (that is, the adjusting unit 2, 2). By adjusting the thickness of the flow rate adjusting plate 4 to an appropriate thickness, the adjusted water flow can be boosted so as not to impair the user's feeling of use.

なお、上記したような各通水孔2b,4bの重ね合わせの状態を変えることに応じて変化する調整部2の通水孔2bの実質的な開口面積の大小による流量調整においては、通水孔2b,4bの口径の大小やその数や形状などに応じて制御できる流量の範囲が決まる。そのため、特に節水割合や使用者の使用感などを大きく変えるには、通水孔2b,4bの口径の大小やその数や形状などが大きく異なって構成された調整部2及び流量調整板4を用いるとよい。すなわち、使用者が求める減水量や使用感などに応じてだけでなく、取り付ける箇所における水量や水圧などにも応じて、調整部2及び流量調整板4の構成を決定するとよい。例えば、高層ビルやマンションなどにおいて、ビル上層部用として大径(開口面積大)、ビル中層部用として中径(開口面積中)、ビル下層部用として小径(開口面積小)にすれば、高さの違いによる水圧の相違に伴って異なる吐水流量(吐出量)に調整・制御することができる。   In the flow rate adjustment based on the size of the substantial opening area of the water passage hole 2b of the adjusting portion 2 that changes in accordance with the change of the overlapping state of the water passage holes 2b and 4b as described above, The range of flow rate that can be controlled is determined according to the size of the holes 2b and 4b, the number and shape thereof. Therefore, in order to greatly change the water saving ratio and the feeling of use of the user in particular, the adjustment unit 2 and the flow rate adjustment plate 4 configured so that the diameters and the number and shape of the water passage holes 2b and 4b are greatly different are provided. Use it. That is, the configuration of the adjusting unit 2 and the flow rate adjusting plate 4 may be determined not only in accordance with the amount of water reduction or feeling of use required by the user, but also in accordance with the amount of water or the water pressure at the location to be attached. For example, in high-rise buildings and condominiums, if you have a large diameter (large opening area) for the upper layer of the building, a medium diameter (medium opening area) for the middle layer of the building, and a small diameter (small opening area) for the lower layer of the building, The water discharge flow rate (discharge amount) can be adjusted and controlled with the difference in water pressure due to the difference in height.

次に、上記節水具1をシングルレバー式水栓の節水装置に適用する実施例について、図3により説明する。図3は、図1に示した節水具1をシングルレバー式水栓の蛇口出口に取り付けるようにした節水装置10の一実施例を示す断面図である。   Next, the Example which applies the said water saving tool 1 to the water saving apparatus of a single lever type faucet is described with reference to FIG. FIG. 3 is a cross-sectional view showing an embodiment of the water-saving device 10 in which the water-saving device 1 shown in FIG. 1 is attached to the faucet outlet of the single lever faucet.

シングルレバー式水栓においては、水栓吐出部(蛇口出口)Sの外周に雄ネジ、キャップCの内周に雌ネジがそれぞれ切ってあり、複数枚のメッシュ部MをキャップCと吐出部(蛇口出口)Sとの間に挟み込み、キャップCをネジ廻して締め込むようになっているものがある。図3に示す節水装置10は、そのようなタイプのシングルレバー式水栓において、上記節水具1をそのフランジ3側の端部1bが水流の下流寄りになるように配置し、その円筒部1cを該シングルレバー式水栓の水栓吐出部S内部に嵌め入れ、適宜のパッキンPを介在させて水栓吐出部Sの端部にフランジ3を当接させ、その下流に複数枚のメッシュ部Mを配置し、キャップCをネジ廻して締め込むことで、これら全体をキャップCと水栓吐出部Sの端部との間に挟み込んで固定するようにしたものである。この構成によれば、上述の節水具1にパッキンPを付加するだけで、既存の蛇口出口にメッシュ部M及びキャップC付きのシングルレバー式水栓に容易に適用できる節水装置10が提供される。
なお、こうした節水装置10は、流れ出る水に対して空気を含ませることのできる泡沫水栓用のキャップ内にも同様に取り付けることができることは言うまでもない。
In the single lever type faucet, a male screw is cut on the outer periphery of the faucet discharge part (faucet outlet) S and a female screw is cut on the inner periphery of the cap C, and a plurality of mesh parts M are connected to the cap C and the discharge part ( Some of them are sandwiched between the tap outlet (S) and the cap C is screwed around. The water-saving device 10 shown in FIG. 3 is a single lever type faucet of this type, in which the water-saving device 1 is disposed such that the end 1b on the flange 3 side is closer to the downstream of the water flow, and its cylindrical portion 1c. Is inserted into the faucet discharge portion S of the single lever type faucet, the flange 3 is brought into contact with the end portion of the faucet discharge portion S with an appropriate packing P interposed therebetween, and a plurality of mesh portions downstream thereof M is arranged and the cap C is screwed and tightened so that the whole is sandwiched and fixed between the cap C and the end of the faucet discharge part S. According to this configuration, it is possible to provide a water-saving device 10 that can be easily applied to a single lever faucet with a mesh portion M and a cap C at an existing faucet outlet simply by adding a packing P to the water-saving device 1 described above. .
Needless to say, such a water-saving device 10 can be similarly installed in a cap for a foam faucet that can contain air with respect to flowing water.

上記実施例2の例では、メッシュ部Mでは網目が粗過ぎるため、節水具1の各通水孔2b、4bで絞られた水流が、その下流のメッシュ部Mであまり干渉されることなく、そのまま通過してしまい、最終的に吐き出される水流が蛇口出口一杯に広がらず、比較的細い流れになりがちである。よって、そのままでは使用者に対して視覚的にその水量の少なさを感じさせてしまうことがある。図4に示す実施例は、そのような不都合を改善できるものである。図4の実施例では、既存のメッシュ部Mに代えて、整流手段5を設けたものである。図4(a)は、節水具1の下流に設置される整流手段5の一例を示す分解斜視図、(b)は節水具1と整流手段5を含む節水装置10を水栓吐出部(蛇口出口)Sに取り付けた状態の断面図である。   In the example of the second embodiment, since the mesh portion M is too coarse, the water flow squeezed by the water passage holes 2b and 4b of the water-saving device 1 is not interfered so much by the mesh portion M downstream thereof. The water flow that passes through as it is and is finally discharged does not spread to the full outlet of the faucet, and tends to be a relatively thin flow. As a result, the user may visually feel that the amount of water is small. The embodiment shown in FIG. 4 can improve such an inconvenience. In the embodiment of FIG. 4, the rectifying means 5 is provided in place of the existing mesh portion M. 4A is an exploded perspective view showing an example of the rectifying means 5 installed downstream of the water-saving device 1, and FIG. 4B is a faucet discharger (faucet) including the water-saving device 1 and the rectifying means 5. It is sectional drawing of the state attached to the exit S. FIG.

図4に示す節水装置10は、図1に示した節水具1と、複数の部材からなる整流キット(整流手段)5とを組み合わせて構成される。節水具1については上記実施例1に示した節水具1(図1参照)と同じ構成であるから、ここでの説明は省略する。整流キット5は該節水具1の下流に配置されるものであって、図4(a)に示すように、この実施例に示す整流キット5は上から順に受圧部5aと2枚の均等板5b、5cとにより構成される。受圧部5aは、中央部分が凸状に突出した突出部5a0に形成されており、周辺はフランジ部となっている。該受圧部5aの突出部5a0は、節水具1の円筒部1a内にフランジ3側から略ぴたりと嵌め込まれるように配置されるようになっており、そのような嵌め込みに適した寸法を持つ。また、該受圧部5aの突出部5a0には、通水孔2bの直下に位置する箇所を除いて、比較的小さい多数の通水孔が設けられており、これらの通水孔の合計開口面積は、絞り量を決定する調整部2の通水孔2bの合計開口面積よりも広い。周辺のフランジ部の外径は、節水具1のフランジ3の外径よりも幾分大きく、キャップCの内径にフィットして嵌り込むサイズである。   A water-saving device 10 shown in FIG. 4 is configured by combining the water-saving device 1 shown in FIG. 1 and a rectifying kit (rectifying means) 5 made up of a plurality of members. Since the water-saving device 1 has the same configuration as the water-saving device 1 (see FIG. 1) shown in the first embodiment, the description thereof is omitted here. The rectifying kit 5 is disposed downstream of the water-saving device 1. As shown in FIG. 4 (a), the rectifying kit 5 shown in this embodiment includes a pressure receiving portion 5a and two equal plates in order from the top. 5b and 5c. The pressure receiving portion 5a is formed in a protruding portion 5a0 whose central portion protrudes in a convex shape, and its periphery is a flange portion. The protruding portion 5a0 of the pressure receiving portion 5a is arranged so as to be fitted almost perfectly into the cylindrical portion 1a of the water-saving device 1 from the flange 3 side, and has a size suitable for such fitting. In addition, the protruding portion 5a0 of the pressure receiving portion 5a is provided with a relatively large number of water passage holes except for a portion located directly below the water passage hole 2b, and the total opening area of these water passage holes. Is wider than the total opening area of the water passage holes 2b of the adjusting portion 2 that determines the amount of restriction. The outer diameter of the peripheral flange portion is somewhat larger than the outer diameter of the flange 3 of the water-saving device 1, and is a size that fits and fits into the inner diameter of the cap C.

受圧部5aの下流に配置される2枚の均等板5b、5cは、比較的小さい多数の通水孔が設けられた多孔板部からなっていて、その周縁のリム部が多孔板部より幾分高い。よって、各均等板5b、5cにおける多孔板部は図示のような凹みを成しており、多孔板部の全域にわたる凹みに対応して適宜の空間をそれぞれ存在させている。また、受圧部5aと同様に、均等板5b、5cの外径も、節水具1のフランジ3の外径よりも幾分大きく、キャップCの内径にフィットして嵌り込むサイズである。各均等板5b、5cの通水孔の合計開口面積も、絞り量を決定する調整部2の通水孔2bの合計開口面積よりも広い。   The two equal plates 5b and 5c arranged downstream of the pressure receiving portion 5a are composed of a perforated plate portion provided with a relatively large number of water passage holes. It ’s expensive. Therefore, the perforated plate portion in each of the equal plates 5b and 5c has a recess as shown in the figure, and an appropriate space exists corresponding to the recess over the entire area of the perforated plate portion. Similarly to the pressure receiving portion 5a, the outer diameters of the equal plates 5b and 5c are somewhat larger than the outer diameter of the flange 3 of the water-saving device 1, and are sized to fit and fit into the inner diameter of the cap C. The total opening area of the water passage holes of the equal plates 5b and 5c is also wider than the total opening area of the water passage holes 2b of the adjusting unit 2 that determines the amount of restriction.

図4(b)に示すように、上記節水具1をそのフランジ3側の端部1bが水流の下流寄りになるように配置し、その円筒部1cをシングルレバー式水栓の水栓吐出部Sの内部に嵌め入れ、パッキンPを介在させて水栓吐出部Sの端部にフランジ3を当接させ、その下流に受圧部5a、均等板5b、5cからなる整流キット5を配置し、キャップCをネジ廻して締め込むことで、これら全体をキャップCと水栓吐出部Sの端部との間に挟み込んで固定する。   As shown in FIG. 4B, the water-saving device 1 is arranged so that the end 1b on the flange 3 side is closer to the downstream of the water flow, and the cylindrical portion 1c is a faucet discharge portion of a single lever faucet. The flange 3 is brought into contact with the end portion of the faucet discharge portion S with the packing P interposed therebetween, and the rectifying kit 5 including the pressure receiving portion 5a and the equal plates 5b and 5c is disposed downstream thereof. By tightening the cap C by screwing, the whole is sandwiched and fixed between the cap C and the end portion of the faucet discharge portion S.

上記構成からなる整流キット5の作用について説明する。節水具1の調整部2の通水孔2bから吐き出された水流は、その直下の受圧部5aの突出部5a0の通水孔のない部分に当接する(受圧される)。そのため、吐き出された水流は該部分に当接して周囲に広がり、その回りにある多数の通水孔を通って落下する。こうして、受圧部5aの存在により、節水具1において調整された水流が減圧される。次に、受圧部5aを通過した水流は、最初の均等板5bの多孔板部の全域にわたる凹みに対応した空間に入り、該多孔板部の全域にわたって広がる。こうして、受圧部5aから出る水流が蛇口出口面積の全体にわたって略均等に振り分けられる。蛇口出口面積の全体にわたって略均等に振り分けられた水流は、均等板5b(多孔板部)の全域にわたって略均等に設けられた多数の通水孔を通過し、落下する。こうして、最終的に吐き出される水流が蛇口出口一杯に広がるようにする整流効果が実現される。すなわち、節水作用によって、水流量が減少されても、蛇口出口一杯に広がるよう整流された吐出水流によって、感覚的にも視覚的にも、使用者の使用感が損なわれることがない、という優れた効果を奏する。   The operation of the rectifying kit 5 having the above configuration will be described. The water flow discharged from the water passage hole 2b of the adjustment part 2 of the water-saving device 1 abuts (is received by pressure) on a portion of the protruding part 5a0 of the pressure receiving part 5a directly below the part without the water passage hole. Therefore, the discharged water flow abuts on the portion and spreads around, and falls through a large number of water passages around it. Thus, the water flow adjusted in the water-saving device 1 is decompressed due to the presence of the pressure receiving portion 5a. Next, the water flow that has passed through the pressure receiving portion 5a enters a space corresponding to the depression over the entire porous plate portion of the first uniform plate 5b, and spreads over the entire porous plate portion. Thus, the water flow coming out of the pressure receiving part 5a is distributed substantially evenly over the entire faucet outlet area. The water flow distributed substantially uniformly over the entire faucet outlet area passes through a large number of water holes provided substantially uniformly over the entire area of the uniform plate 5b (perforated plate portion) and falls. In this way, a rectifying effect is realized so that the water flow finally discharged spreads to the faucet outlet. In other words, even if the water flow rate is reduced by the water-saving action, the user's feeling of use is not impaired, both sensorially and visually, by the discharge water flow rectified so as to spread all the way to the faucet outlet. Has the effect.

この実施例では、2枚の均等板5b,5cが設けられている。これは、均等板による整流効果を相加的若しくは相乗的に高めるためである。すなわち、上段の均等板5bを通過した水流は、さらに、2段目の均等板5cの多孔板部の全域にわたる凹みに対応した空間に入り、該多孔板部の全域にわたって広がる。こうして、上段の均等板5bから出る水流が蛇口出口面積の全体にわたって更に均等に振り分けられるようにされる。こうして、蛇口出口面積の全体にわたって一層均等に振り分けられた水流は、均等板5c(多孔板部)の全域にわたって略均等に設けられた多数の通水孔を通過し、落下する。こうして、最終的に吐き出される水流が蛇口出口一杯により一層均等に広がるようにする整流効果が実現される。明らかなように、2枚の均等板5b,5cの各通水孔がそれぞれ同位置で重なったのでは、相加的若しくは相乗的な整流効果は薄れる。よって、複数枚の均等板5b、5cを重ねて配置する場合には、各均等板5b、5cの多孔板部に形成された複数の通水孔の位置がすべて一致することのないように、それぞれが適宜ずれた状態となるようにして配置するとよい(図4(b)参照)。そのためには、各均等板5b、5cとしてその多孔板部における通水孔の配置パターンが互いに異なるものを使用するか、あるいは同一構成の多孔板部からなる均等板を使用する場合は、通水孔の配置パターンが同位置で重ならないように適宜相対的に回転させた状態で配置すればよい。後者の配置を容易にするためには、各均等板5b、5c同士の周縁リム部に簡単なキー結合構造(一方にキー凹み、他方にキー突起)を設け、所定の相対的回転ずれをもたせて各均等板5b、5c同士を容易に積み重ねることができるようにするとよい。なお、均等板5b、5cは、2枚重ねに限らず、1枚だけであってもよいし、あるいは3枚以上重ねてもよい。   In this embodiment, two equal plates 5b and 5c are provided. This is to increase the rectifying effect by the equal plate additively or synergistically. That is, the water flow that has passed through the upper uniform plate 5b further enters a space corresponding to the depression over the entire porous plate portion of the second uniform plate 5c, and spreads over the entire porous plate portion. In this way, the water flow coming out from the upper uniform plate 5b is more evenly distributed over the entire faucet outlet area. In this way, the water flow that is more evenly distributed over the entire faucet outlet area passes through a large number of water holes provided substantially uniformly over the entire area of the equal plate 5c (perforated plate portion) and falls. In this way, a rectifying effect is realized so that the finally discharged water flow spreads more evenly with the full outlet of the faucet. Obviously, if the water flow holes of the two equal plates 5b and 5c overlap at the same position, the additive or synergistic rectifying effect is reduced. Therefore, when a plurality of equal plates 5b, 5c are arranged in an overlapping manner, the positions of the plurality of water passage holes formed in the porous plate portions of the respective equal plates 5b, 5c do not all coincide. It is good to arrange so that each may shift | deviate suitably (refer FIG.4 (b)). For this purpose, when the equal plates 5b and 5c are different from each other in the arrangement pattern of the water passage holes in the perforated plate portion, or when using equal plates made up of the same configuration perforated plate portion, What is necessary is just to arrange | position in the state rotated relatively suitably so that the arrangement pattern of a hole may not overlap in the same position. In order to facilitate the latter arrangement, a simple key coupling structure (key depression on one side and key projection on the other side) is provided on the peripheral rim portion between the equal plates 5b and 5c to give a predetermined relative rotational deviation. It is preferable that the uniform plates 5b and 5c can be easily stacked. In addition, the equal plates 5b and 5c are not limited to two, but may be only one or may be three or more.

なお、整流キット5を構成する受圧部5a及び均等板5b、5cの数やこれらの板に形成する孔の数、あるいは各板を設定する際の各板の組み合わせ方などは上記のものに限らず、適宜のものであってよい。例えば、受圧部や均等板のそれぞれを1段又は多段構成にするなどしてよい。   The number of pressure receiving portions 5a and equal plates 5b, 5c constituting the rectifying kit 5, the number of holes formed in these plates, or the combination of the plates when setting the plates are not limited to those described above. It may be appropriate. For example, each of the pressure receiving portion and the equal plate may have a single stage or a multistage structure.

図5は、整流キット5における受圧部5aの変形例を示す。この変形例に係る受圧部5a1は、図4の突出部5a0と略同様に円筒部1cの内部に嵌まり込む外径と多数の通水孔を設けて成る突出部5a10を具備しており、さらにその上に突出した複数の突出部5a11を具備する。上部の突出部5a11はその上部に位置する調整部2の通水孔2bの数と同じ数だけ形成されており、その外径は通水孔2bの径と同程度の大きさを持つ。また、この突出部5a11に通水孔はない。この構成により、調整部2の通水孔2bから吐き出された水流の一部は、その直下の受圧部5a1の上部の突出部5a11に当接し(受圧され)、該上部突出部5a11の周縁を伝って、下部突出部5a10の上に落下する。落下した水流は下部突出部5a10の上を広がり、そこに設けられている多数の通水孔を通って落下する。こうして、前述と同様に、受圧部5a1の存在により、節水具1において調整された水流が減圧される。受圧部5a1を通過した水流は、前述と同様に、均等板5b,5cで処理される。図5の受圧部5a1は、図4の受圧部5aよりも減圧効果が高く、水流の勢いをより一層減ずるので、均等板5b,5cの数を減らし、その代わりにメッシュ板M等で代替するようにしてもよい。   FIG. 5 shows a modification of the pressure receiving portion 5 a in the rectifying kit 5. The pressure receiving portion 5a1 according to this modification includes a protruding portion 5a10 provided with an outer diameter and a large number of water passage holes fitted into the cylindrical portion 1c in substantially the same manner as the protruding portion 5a0 of FIG. Further, a plurality of projecting portions 5a11 projecting thereon are provided. The upper protrusions 5a11 are formed in the same number as the number of the water passage holes 2b of the adjustment unit 2 positioned on the upper part, and the outer diameter thereof is approximately the same as the diameter of the water passage holes 2b. Moreover, this protrusion part 5a11 does not have a water passage hole. With this configuration, a part of the water flow discharged from the water flow hole 2b of the adjustment unit 2 abuts (being received pressure) on the upper protruding portion 5a11 of the pressure receiving portion 5a1 directly below the water flow hole 2b, and the peripheral edge of the upper protruding portion 5a11. Then, it falls on the lower protrusion 5a10. The dropped water flow spreads over the lower protrusion 5a10 and falls through a number of water holes provided therein. Thus, as described above, the water flow adjusted in the water-saving device 1 is depressurized due to the presence of the pressure receiving portion 5a1. The water flow that has passed through the pressure receiving portion 5a1 is processed by the equal plates 5b and 5c as described above. The pressure receiving portion 5a1 in FIG. 5 has a higher pressure reducing effect than the pressure receiving portion 5a in FIG. 4 and further reduces the momentum of the water flow. Therefore, the number of the equal plates 5b and 5c is reduced and replaced with a mesh plate M or the like instead. You may do it.

図6は、整流キット5における受圧部5a1の更なる変形例を示す。この変形例に係る受圧部5a2は、図4の突出部5a10と略同様に円筒部1cの内部に嵌まり込む外径と多数の通水孔を設けて成る突出部5a20とその上に突出した突出部5a21とを具備しており、さらにその上に突出した突出部5a22を具備する。中間の突出部5a21の外径は円筒部1cの内径よりも十分小さく、また通水孔は不要である。さらにその上部の突出部5a22は、図4の突出部5a0と略同様に、円筒部1cの内部に略ぴたりと嵌まり込む外径と多数の通水孔を設けて成り、かつ、通水孔2b直下の部分に通水孔はない。この構成により、調整部2の通水孔2bから吐き出された水流は、その直下の受圧部5a2の上部の突出部5a22の通水孔のない部分に当接し(受圧され)、そのために吐き出された水流は該部分に当接して周囲に広がり、そこにある多数の通水孔を通って落下し、次いで、中間の突出部5a21に当接し(受圧され)該突出部5a21の周縁を伝って、あるいは直接的に、下部突出部5a20の上に落下する。落下した水流は下部突出部5a20の上を広がり、そこに設けられている多数の通水孔を通って落下する。こうして、前述と同様に、受圧部5a2の存在により、節水具1において調整された水流がより一層減圧される。受圧部5a2を通過した水流は、前述と同様に、均等板5b,5cで処理される。図6の受圧部5a2は、図4、図5の受圧部5a、5a1よりも一層減圧効果が高く、水流の勢いを更により一層減ずるので、均等板5b,5cの数を減らし、その代わりにメッシュ板M等で代替するようにしてよい。   FIG. 6 shows a further modification of the pressure receiving portion 5a1 in the rectifying kit 5. The pressure-receiving part 5a2 according to this modification is substantially the same as the protruding part 5a10 of FIG. 4 and protrudes on and above the protruding part 5a20 having an outer diameter and a large number of water passage holes that fit inside the cylindrical part 1c. And a protruding portion 5a22 protruding above the protruding portion 5a21. The outer diameter of the intermediate protrusion 5a21 is sufficiently smaller than the inner diameter of the cylindrical portion 1c, and no water passage hole is required. Further, the upper protruding portion 5a22 is provided with an outer diameter and a large number of water passage holes that are substantially fitted inside the cylindrical portion 1c, as in the case of the protrusion portion 5a0 in FIG. There is no water passage hole in the part directly under 2b. With this configuration, the water flow discharged from the water passage hole 2b of the adjustment unit 2 abuts (is received by) the portion of the protrusion 5a22 on the upper portion of the pressure receiving portion 5a2 directly below the water passage hole, and is thus discharged. The water flow abuts on this portion and spreads around, falls through a number of water passage holes there, and then abuts (is received by pressure) on the intermediate protrusion 5a21 and travels around the periphery of the protrusion 5a21. Or directly falls on the lower protrusion 5a20. The dropped water flow spreads over the lower protrusion 5a20 and falls through a number of water holes provided therein. Thus, as described above, the water flow adjusted in the water-saving device 1 is further reduced in pressure due to the presence of the pressure receiving portion 5a2. The water flow that has passed through the pressure receiving portion 5a2 is processed by the equal plates 5b and 5c as described above. The pressure receiving portion 5a2 in FIG. 6 has a higher pressure reducing effect than the pressure receiving portions 5a and 5a1 in FIGS. 4 and 5 and further reduces the momentum of the water flow, thereby reducing the number of equal plates 5b and 5c. A mesh plate M or the like may be substituted.

一般的に、節水具1に流入する水の水圧が増すと、調整部3の通水孔3aから吐き出される水流も勢いを増す。そこで、整流キット5における受圧部5aを、流入する水の水圧にあわせて上記図5又は図6に示したような受圧部5a1,5a2に適宜に取り替えて節水具1を設置するとよい。こうすると、受圧部を交換するだけで調整部2の通水孔2bから吐き出される水流の勢いを調整することができ、どのような水圧のシングルレバー式の水栓であってもソフトな水流を得ることができるようになる。   Generally, when the water pressure flowing into the water-saving device 1 increases, the water flow discharged from the water passage hole 3a of the adjustment unit 3 also increases the momentum. Therefore, the water-saving device 1 may be installed by appropriately replacing the pressure receiving portion 5a in the rectifying kit 5 with the pressure receiving portions 5a1 and 5a2 as shown in FIG. In this way, the momentum of the water flow discharged from the water passage hole 2b of the adjustment unit 2 can be adjusted by simply replacing the pressure receiving unit, and a soft water flow can be obtained regardless of the single lever type faucet of any water pressure. Be able to get.

図4〜図6に示されたような新規かつ有用な整流キット5は、図1に示されたような節水具1に限らず、既知又は未知の他の如何なる節水具と組み合わせてもよく、その場合でも、上述したような減圧と整流(蛇口出口面積全域にわたる略均一的な水流の広がり)に関して有利な作用・効果をもたらす。   The novel and useful rectifying kit 5 as shown in FIGS. 4 to 6 is not limited to the water saving device 1 as shown in FIG. 1, and may be combined with any other known or unknown water saving device, Even in such a case, advantageous effects and effects are brought about with respect to pressure reduction and rectification (a substantially uniform water flow spread over the entire area of the faucet outlet) as described above.

上記各実施例では、本実施例に係る節水具1を、蛇口出口に設置するタイプの節水装置10に適用する例、例えばシングルレバー式水栓の蛇口出口に設置する節水装置10に適用する例について説明したが、これに限らず、該節水具1をハンドルコック式水栓用節水器あるいはシャワー用節水器などのように流路の途中に設置するタイプの節水器としても使用することができる。その場合、該節水具1の水流方向に対する上下の向きを反転して使用する。以下、この場合の実施例について図7を用いて説明する。図7は、上記節水具1をハンドルコック式水栓用節水器あるいはシャワー用節水器などのように流路の途中に設置するタイプの節水器としても使用する場合を示す側断面図である。   In each of the above-described embodiments, the water-saving device 1 according to this embodiment is applied to a water-saving device 10 of a type installed at the faucet outlet, for example, an example applied to the water-saving device 10 installed at the faucet outlet of a single lever faucet. However, the present invention is not limited to this, and the water-saving device 1 can also be used as a water-saving device that is installed in the middle of the flow path, such as a water-saving device for a faucet of a handle cock or a water-saving device for a shower. . In that case, the water saving tool 1 is used by reversing the vertical direction with respect to the water flow direction. Hereinafter, an embodiment in this case will be described with reference to FIG. FIG. 7 is a side cross-sectional view showing a case where the water-saving device 1 is also used as a water-saving device of the type installed in the middle of the flow path, such as a handle cock type water-saving device for faucets or a water-saving device for showers.

図7に示すように、本実施例に係る上述の節水具1をハンドルコック式水栓用節水器あるいはシャワー用節水器などのように流路の途中に設置するタイプの節水器として使用する場合には、シングルレバー式水栓用節水器として使用する場合とは逆に、該節水具1の上下を反対にして、フランジ3側の端部1bを上流寄りに配置し、該フランジ3をスパウトZの上端に係止させ、該スパウトZを締め付け固定するためのキャップネジ等の手段によって固定する。このように流路の途中のスパウトZの上端に節水具1を設置するための構造は公知のものを適宜用いればよいため、その詳細は特に説明しない。   As shown in FIG. 7, when the above-described water-saving device 1 according to the present embodiment is used as a water-saving device that is installed in the middle of a flow path, such as a handle cock-type faucet water saving device or a shower water saving device. On the other hand, contrary to the case of use as a single lever faucet water-saving device, the water-saving device 1 is turned upside down, the end 1b on the flange 3 side is arranged upstream, and the flange 3 is spouted. The spout Z is locked with the upper end of Z and fixed by means such as a cap screw for fastening and fixing the spout Z. Thus, since the structure for installing the water saving tool 1 in the upper end of the spout Z in the middle of a flow path should just use a well-known thing suitably, the detail is not demonstrated in particular.

図1に示したような節水具1を単に反転して設置した状態では、絞り量を設定する通水孔2bを設けた調整部2が上に、通水孔4bを設けた調整部4が下に位置することになるが、これでは調整部4が水圧により取れてしまう恐れがある。そこで、この図7に示した実施例のように、節水具1本体のみを反転した状態で調整部4を上から取付部材Nによって取り付けたものをスパウトZに取り付けるとよい。この構成によると、上述したのと同様に、各調整部2,4の通水孔2b,4bの相対的な位置関係により決まる通水孔2bの実質的な開口面積に応じて、水流が絞られ、通水孔2bの実質的な開口面積以外の個所(障害物)によって干渉/緩衝され、水流調整がなされる。また、調整部2から円筒部1cの下流端部1aまでに或る程度の距離が存在するので、この距離分の円筒内側壁が水流ガイド壁(若しくはスリーブ)6となり、整流作用を得ることができる。これによっても、調整部2において水流を絞ることによって生じるかもしれない好ましくないジェット流のような急勢な水流が蛇口から出る恐れを軽減することができる。すなわち、調整部2において絞られた水流が勢いよく飛び出すが、該飛び出した水は当該節水具1の下流寄りに形成された水流ガイド壁(若しくはスリーブ)6の壁面に衝突することから、該スリーブ6において水の整流が行われてスパウトZ内を水が滑らかに流れていくようになる。なお、一般に、このように流路の途中に節水具1を配置する場合は、上述のような整流キット5(図4参照)を配置しなくても、スパウトZ等の流路の存在によって水流の整流化が図れる。しかし、スパウトZ自体の長さが短い場合には、スパウトZによる整流作用があまり期待できず、好ましくないジェット流が吐出されるおそれがある。しかし、本実施例のように、円筒部1cの下流端部1a寄りに水流ガイド壁(若しくはスリーブ)6を形成することにより、水流の整流化を促進することができ、短いスパウトZを使用する場合であっても、好ましくないジェット流が吐出されるおそれを軽減できる。このように、本発明に係る節水具1はシングルレバー式水栓に用いることができるだけでなく、ハンドルコック式水栓にも用いることができるようになっている。こうしたことは、節水具1を製作する際にかかるコストを低減することができる、実際に節水具を配置する際に持ち運ぶ部材が少なくて済む、などの点で有利である。   In a state where the water-saving device 1 as shown in FIG. 1 is simply inverted and installed, the adjustment unit 2 provided with the water passage hole 2b for setting the throttle amount is on the upper side, and the adjustment unit 4 provided with the water passage hole 4b is provided on the upper side. Although it will be located below, there is a possibility that the adjustment unit 4 may be removed by water pressure. Therefore, as in the embodiment shown in FIG. 7, it is preferable to attach to the spout Z the adjustment unit 4 attached from above with the attachment member N in a state where only the main body of the water-saving device 1 is inverted. According to this configuration, as described above, the water flow is reduced according to the substantial opening area of the water passage hole 2b determined by the relative positional relationship between the water passage holes 2b and 4b of the adjusting portions 2 and 4. The water flow is adjusted by interference / buffering by a portion (obstacle) other than the substantial opening area of the water passage hole 2b. In addition, since there is a certain distance from the adjusting portion 2 to the downstream end portion 1a of the cylindrical portion 1c, the inner wall of the cylinder corresponding to this distance becomes the water flow guide wall (or sleeve) 6 to obtain a rectifying action. it can. This also reduces the risk of a rushing water flow, such as an undesired jet flow, that may be caused by squeezing the water flow in the adjusting unit 2 from the faucet. That is, the water flow squeezed out in the adjusting portion 2 jumps out vigorously, but the water that jumps out collides with the wall surface of the water flow guide wall (or sleeve) 6 formed on the downstream side of the water-saving device 1. 6 rectifies the water so that the water flows smoothly in the spout Z. In general, when the water-saving device 1 is arranged in the middle of the flow path as described above, the flow of water can be reduced due to the presence of the flow path such as the spout Z without arranging the rectifying kit 5 (see FIG. 4) as described above. Can be rectified. However, when the length of the spout Z itself is short, the rectifying action by the spout Z cannot be expected so much and an undesired jet flow may be discharged. However, as in this embodiment, by forming the water flow guide wall (or sleeve) 6 near the downstream end 1a of the cylindrical portion 1c, the flow of the water can be rectified, and a short spout Z is used. Even in this case, the possibility that an undesired jet flow is discharged can be reduced. As described above, the water-saving device 1 according to the present invention can be used not only for a single lever type faucet but also for a handle cock type faucet. This is advantageous in that the cost for manufacturing the water-saving device 1 can be reduced, and the number of members to be carried when the water-saving device is actually arranged is reduced.

節水具1の具体的構成は、上述したものに限らず、種々に変形可能である。図8は、節水具1の変形例を示す断面図である。図8に示す節水具1は、水流調整部2の他に、さらにフランジ3とは反対側の端部1a(つまり水流入口)の円筒部1c内に水流調整部2´を一体的に形成してある。すなわち、通水用の開口を有する隔壁状の2つの調整部2,2´が節水具1の円筒部1c内に形成されている。各調整部2,2´には1又は複数の通水孔2b,2b´がそれぞれ適切な形状、配置及び寸法で開口形成されている。ここでは、中央部に1つの通水孔2bを有する調整部2と、中央孔の周囲に4つの通水孔2b´を有する調整部2´を具えたものを例に示している。流量調整部材7は軸部がスクリュー形状に形成され且つヘッド部にはドライバーなどの取付器具を嵌め込むための溝が形成されており、取付器具により当該流量調整部材7を調整部2´の中央孔に上下動可能な状態で取り付けることができるようになっている。この流量調整部材7のヘッド部と反対側の端面には所定形状の孔を有しない流量調整板7aが形成されており、この流量調整板7aの外形形状は調整部2の通水孔2bに略ぴたりの形状に形成される。流量調整部材7を上下動すると、それに従い水流調整部2の通水孔2bの上面と流量調整部材7の流量調整板7aの下面との間の間隔が変化する。この間隔の大きさ(つまり、前記流量調整板4と調整部2の通水孔2bとの間に形成される流路の大きさ)に応じた水流量の絞り込みがなされることから、間隔の大小を調整することによりスムーズな流量調整を行うことができる。また、調整部2´の通水孔2b´から流れ出る水流が流量調整部材7の流量調整板7aに当たることにより、干渉/緩衝作用が生じ、水流を調整することができるようにもなっている。また、図8(b)に示す変形例のように、水流調整部2´の通水孔2b´の下面部と流量調整部材7の流量調整板7aの上面部との間の間隔を調整することにより、流量調整を行うようにしてあってもよい。
なお、流量調整板7aに所定形状の孔を形成してもよい。こうした場合には、流量調整板7aが調整部2の通水孔2bをほぼ完全に塞ぐ位置まで下降したとしても、所定の吐水流量を確保することができることから都合がよい。
The specific configuration of the water-saving device 1 is not limited to that described above, and can be variously modified. FIG. 8 is a cross-sectional view showing a modified example of the water-saving device 1. In addition to the water flow adjusting portion 2, the water saving tool 1 shown in FIG. 8 further has a water flow adjusting portion 2 'formed integrally in the cylindrical portion 1c of the end 1a opposite to the flange 3 (that is, the water inlet). It is. That is, two partition-shaped adjustment portions 2 and 2 ′ having openings for water passage are formed in the cylindrical portion 1 c of the water-saving device 1. One or a plurality of water passage holes 2b and 2b 'are formed in each adjustment portion 2 and 2' with appropriate shapes, arrangements, and dimensions. Here, an example is shown in which an adjustment portion 2 having one water passage hole 2b in the center and an adjustment portion 2 'having four water passage holes 2b' around the center hole are provided. The flow rate adjusting member 7 has a shaft portion formed in a screw shape and a groove for fitting an attachment device such as a screwdriver in the head portion. The flow rate adjustment member 7 is placed in the center of the adjustment portion 2 ′ by the attachment device. It can be attached to the hole so that it can move up and down. A flow rate adjusting plate 7 a that does not have a hole having a predetermined shape is formed on the end surface opposite to the head portion of the flow rate adjusting member 7, and the outer shape of the flow rate adjusting plate 7 a is formed in the water passage hole 2 b of the adjusting unit 2. It is formed in an almost perfect shape. When the flow rate adjusting member 7 is moved up and down, the distance between the upper surface of the water flow hole 2b of the water flow adjusting unit 2 and the lower surface of the flow rate adjusting plate 7a of the flow rate adjusting member 7 changes accordingly. Since the water flow rate is narrowed in accordance with the size of this interval (that is, the size of the flow path formed between the flow rate adjusting plate 4 and the water passage hole 2b of the adjusting unit 2), Smooth flow rate adjustment can be performed by adjusting the size. Further, when the water flow flowing out from the water flow hole 2b ′ of the adjusting portion 2 ′ hits the flow rate adjusting plate 7a of the flow rate adjusting member 7, interference / buffering action is generated, and the water flow can be adjusted. Further, as in the modification shown in FIG. 8B, the distance between the lower surface portion of the water flow hole 2 b ′ of the water flow adjusting portion 2 ′ and the upper surface portion of the flow rate adjusting plate 7 a of the flow rate adjusting member 7 is adjusted. Therefore, the flow rate may be adjusted.
A hole having a predetermined shape may be formed in the flow rate adjusting plate 7a. In such a case, even if the flow rate adjusting plate 7a is lowered to a position where the water flow hole 2b of the adjusting unit 2 is almost completely closed, it is convenient because a predetermined water discharge flow rate can be secured.

図9は、節水具1の別の変形例を示す断面図である。図9の例では、水流絞り量を調整する調整部2の通水孔(開口)2bを、水流方向に平行ではなく、適宜斜めを成して形成した構成である(好ましくは下面側で中心寄りとなり、その反対側で外側寄りとなっているような斜め方向)。この実施例では流量調整部材7の軸部自身が、流量調整部材7の上下動に従って流量調整を行うようになっている。勿論、この場合においても図8に示すように流量調整部材7の先端部に流量調整板7aを設けておき、これにより流量調整を行うようにしてあってもよい。   FIG. 9 is a cross-sectional view showing another modification of the water-saving device 1. In the example of FIG. 9, the water passage hole (opening) 2b of the adjusting unit 2 that adjusts the water flow restriction amount is formed not to be parallel to the water flow direction but to be appropriately inclined (preferably centered on the lower surface side). A slanted direction that is closer to the outside and opposite to the outside). In this embodiment, the shaft portion itself of the flow rate adjusting member 7 adjusts the flow rate according to the vertical movement of the flow rate adjusting member 7. Of course, in this case as well, as shown in FIG. 8, a flow rate adjusting plate 7a may be provided at the tip of the flow rate adjusting member 7 to adjust the flow rate.

図10は、節水具1の更なる別の変形例を示す断面図である。図10の例では、流路を横切る板(又は隔壁)状に水流調整部2を構成することなく、水流調整部2の複数の通水孔2bを円筒部1cの壁面に形成している。この図10に示す実施例においては、90度の間隔で所定の大きさの開口部をもつ4つの長方形状の通水孔2bが形成されたものを示した。図示で上から来る水流は円筒部1cの外側と管路の内壁との間に入り込み、円筒部1cの側壁面の複数の通水孔2bから円筒部1cの内部に入り込むようになっている。円筒部1cの内部には流量調整部材7が配置されており、該流量調整部材7は円筒部1cの内部に外周面が略一致する形状をした凸部を有する。この構成では、流量調整部材7の上下動により流量調整を行う。すなわち、流量調整部材7を上下動すると該流量調整部材7における凸部の外周面が複数の通水孔2bを部分的に塞いでいくことになるので、これにより通水孔2bの開口面積が変化することになる。こうした複数の通水孔2bの開口面積が変化することに伴い、複数の通水孔2bから円筒部1cの内部に入り込む水量が変化する。つまり、流量調整を実現することができる。
なお、図10(a)に示すように、流量調整部材7の両方に取付器具を嵌め込むための溝が形成されていると、上下どちらの方向からも取り付けることができるようになり便利である。
FIG. 10 is a cross-sectional view showing still another modification of the water-saving device 1. In the example of FIG. 10, the water flow adjusting part 2 is formed in the wall surface of the cylindrical part 1c, without forming the water flow adjusting part 2 in the shape of a plate (or partition wall) that crosses the flow path. In the embodiment shown in FIG. 10, four rectangular water passage holes 2b having openings of a predetermined size are formed at intervals of 90 degrees. In the figure, the water flow coming from above enters between the outside of the cylindrical portion 1c and the inner wall of the pipe, and enters the inside of the cylindrical portion 1c through a plurality of water passage holes 2b on the side wall surface of the cylindrical portion 1c. A flow rate adjusting member 7 is disposed inside the cylindrical portion 1c, and the flow rate adjusting member 7 has a convex portion having a shape in which the outer peripheral surface substantially coincides with the inside of the cylindrical portion 1c. In this configuration, the flow rate is adjusted by the vertical movement of the flow rate adjusting member 7. That is, when the flow rate adjusting member 7 is moved up and down, the outer peripheral surface of the convex portion of the flow rate adjusting member 7 partially blocks the plurality of water passage holes 2b, so that the opening area of the water passage hole 2b is increased. Will change. As the opening areas of the plurality of water passage holes 2b change, the amount of water that enters the cylindrical portion 1c from the plurality of water passage holes 2b changes. That is, flow rate adjustment can be realized.
In addition, as shown to Fig.10 (a), when the groove | channel for fitting an attachment tool in both of the flow volume adjustment member 7 is formed, it will come to be able to attach from any direction up and down, and is convenient. .

図10(b)に示すように、円筒部1cの側壁面に形成する複数の通水孔2bは、水流方向に垂直ではなく、適宜斜めを成して形成した構成であってよい。また、ここに示す実施例の節水具1は、流量調整部材7の軸部の外周面が前記複数の通水孔2bを部分的に塞ぐことで流量調整を実現するものである。
なお、この場合において、流量調整部材7の軸部に側面から底面へと抜ける所定の大きさ・形状の複数の孔を設けておき、この孔と側面の通水孔との重ね合わせにより、実質的な開口面積(つまり流路の大きさ)を決定して流量を調整することができるようにしてよい。
As shown in FIG. 10 (b), the plurality of water passage holes 2b formed on the side wall surface of the cylindrical portion 1c may be formed so as to be appropriately inclined rather than perpendicular to the water flow direction. Moreover, the water-saving tool 1 of the Example shown here implement | achieves flow volume adjustment because the outer peripheral surface of the axial part of the flow volume adjustment member 7 partially block | closes these water flow holes 2b.
In this case, a plurality of holes of a predetermined size and shape are provided in the shaft portion of the flow rate adjusting member 7 from the side surface to the bottom surface, and the hole and the water passage hole on the side surface are overlapped to substantially The flow rate may be adjusted by determining a specific opening area (that is, the size of the flow path).

図11は、節水具1の更なる別の変形例を示す断面図である。図11の例では、円筒部1cの内部にではなく、円筒部1cの外部に流量調整部材Rを配置している。上述した図10と同様に、調整部2の複数の通水孔2bが円筒部1cの壁面に形成されており、図示で上から来る水流は該円筒部1cの側壁面の複数の通水孔2bから円筒部1cの内部に入り込むようになっている。この構成では、円筒部1cの外部にネジ式に取付可能なリング状の流量調整部材Rを上下動することにより、流量調整を行う。すなわち、流量調整部材Rを上下動すると該流量調整部材Rにおける内周面が複数の通水孔2bを部分的に塞いでいくことになるので、これにより通水孔2bの実質的な開口面積(つまり流路の大きさ)が変化することになる。こうした複数の通水孔2bの実質的な開口面積が変化することに伴い、複数の通水孔2bから円筒部1cの内部に入り込む水量が変化する。つまり、流量調整を実現することができる。   FIG. 11 is a cross-sectional view showing still another modification of the water-saving device 1. In the example of FIG. 11, the flow rate adjusting member R is arranged outside the cylindrical portion 1c, not inside the cylindrical portion 1c. Similarly to FIG. 10 described above, the plurality of water passage holes 2b of the adjusting portion 2 are formed in the wall surface of the cylindrical portion 1c, and the water flow coming from above in the drawing is a plurality of water passage holes on the side wall surface of the cylindrical portion 1c. It enters into the inside of the cylindrical part 1c from 2b. In this configuration, the flow rate is adjusted by moving up and down a ring-shaped flow rate adjusting member R that can be screwed to the outside of the cylindrical portion 1c. That is, when the flow rate adjusting member R is moved up and down, the inner peripheral surface of the flow rate adjusting member R partially closes the plurality of water passage holes 2b. (That is, the size of the flow path) changes. As the substantial opening area of the plurality of water passage holes 2b changes, the amount of water that enters the cylindrical portion 1c from the plurality of water passage holes 2b changes. That is, flow rate adjustment can be realized.

また、図11(b)に示すように、円筒部1cの外部に配置する流量調整部材Rの側面に通水孔Raを設けておき、この通水孔Raと円筒部1cの側面の通水孔2bとの重ね合わせ具合により、流量を調整することができるようにしてよい。この場合には、円筒部1cの外周に沿ってリング状の流量調整部材Rを自在に回転する。すると、円筒部1cの側面の通水孔2bの位置と流量調整部材Rの通水孔Raの位置との相対的な位置が変化し、通水孔2b,Raの重ね合わせ状態が変わる。すなわち、通水孔2bの実質的な開口面積(つまり流路の大きさ)が変化する。この開口面積の大小によって、水流量の絞り込みがなされ、スムーズな流量調整が行われる。流量調整部材Rは、取付部材Nにより円筒部1cの上端に締め付けられて固定される。   Moreover, as shown in FIG.11 (b), the water flow hole Ra is provided in the side surface of the flow volume adjustment member R arrange | positioned outside the cylindrical part 1c, and water flow of this water flow hole Ra and the side surface of the cylindrical part 1c is carried out. The flow rate may be adjusted depending on the degree of overlap with the hole 2b. In this case, the ring-shaped flow rate adjusting member R is freely rotated along the outer periphery of the cylindrical portion 1c. Then, the relative position between the position of the water passage hole 2b on the side surface of the cylindrical portion 1c and the position of the water passage hole Ra of the flow rate adjusting member R changes, and the overlapping state of the water passage holes 2b and Ra changes. That is, the substantial opening area (that is, the size of the flow path) of the water passage hole 2b changes. Depending on the size of the opening area, the water flow rate is narrowed down and smooth flow rate adjustment is performed. The flow rate adjusting member R is fastened and fixed to the upper end of the cylindrical portion 1c by the mounting member N.

なお、図8から図11に示した各実施例において、流量調整部材7の軸上に吐水水量に応じた所定位置を示す表示を予めいくつか記しておき、必要とされる吐水水量に応じて前記表示に従い適宜の位置で流量調整部材7をポンチ打ちして固定することができるようにするとよい。こうすると、誰でもが所望の吐水水量が得られるように流量の調整を行うことが簡単にできるようになる。   In addition, in each Example shown in FIGS. 8-11, several indications which show the predetermined position according to the amount of discharged water on the axis | shaft of the flow volume adjustment member 7 are described previously, and according to the amount of discharged water required. It is preferable that the flow rate adjusting member 7 can be punched and fixed at an appropriate position in accordance with the display. In this way, anyone can easily adjust the flow rate so that a desired amount of discharged water can be obtained.

図4〜図6に示す節水装置10において、受圧部5a,5a1,5a2を省略し、節水具1と均等板5c,5bとで節水装置10を構成することも可能である。そのような構成は、水圧の低い場所で使用するのに適する。
さらに、均等板5c,5bは、従来知られたメッシュ部Mの代替品として、蛇口出口にて用いることができる。メッシュ部Mではごみがつまり易かったり、耐久性に乏しいなどの欠点があるが、本発明に係る均等板5c,5bは、金属板等を多孔加工するものであるので、耐久性があり、また、メッシュのような目づまりも起こりにくい。
なお、上述した各実施例においては回転変位により流量調整を行うことができるようにしたものを示したがこれに限らず、直線変位や斜行的な変位により流量調整を行うことができるようにしたものであってもよい。
In the water-saving device 10 shown in FIGS. 4 to 6, the pressure-receiving portions 5a, 5a1, and 5a2 may be omitted, and the water-saving device 10 may be configured with the water-saving device 1 and the equal plates 5c and 5b. Such a configuration is suitable for use in low water pressure locations.
Furthermore, the equal plates 5c and 5b can be used at the faucet outlet as an alternative to the conventionally known mesh portion M. The mesh part M has disadvantages such as easy dusting and poor durability. However, the uniform plates 5c and 5b according to the present invention are made of a porous metal plate or the like, and are durable. Clogging is unlikely to occur.
In each of the embodiments described above, the flow rate can be adjusted by rotational displacement. However, the present invention is not limited to this, and the flow rate can be adjusted by linear displacement or oblique displacement. It may be what you did.
