Description

【０００１】
【発明の属する技術分野】
この発明は、水栓用節水部材およびシャワ用節水部材に関するものである。
【０００２】
【従来の技術および発明が解決しようとする課題】
図７に示すように、例えば水栓本体７１に接続された吐水管７２からは、通常、水栓本体側の水圧の変化に比例した水量が吐水するので、水圧が高くなった場合は水量が増加することになる。一方、水栓本体７１と吐水管７２の接続部に、水栓本体側の水圧が変化しても常に同じ水量を吐水管７２から吐水させる定流量弁を設けることにより節水効果をうることができるけれども、水栓本体側の水圧の変化に比例した水量を吐水管から吐水させながら節水もできる水栓用節水部材が望まれる。
【０００３】
また、図８に示すように、シャワホース側の水圧が変化しても常に同じ水量を、シャワヘッド８１の吐水口８３に装着されたシャワ板８２から吐水させる定流量弁をシャワヘッド８１とシャワホース８２の接続部に設けることにより節水効果をうることができるけれども、シャワホース側の水圧の変化に比例した水量をシャワ板８２から吐水させながら節水もできるシャワ用節水部材が望まれる。
【０００４】
また、シャワ板に設ける吐水孔の数を通常のものより少なくすることにより、節水できるようにしたシャワがあるけれども、シャワ板の吐水孔の数を減らすことなく節水できるシャワが望まれている。
【０００５】
この発明は、上記問題に鑑みてなしたもので、水栓本体側あるいはシャワホース側の水圧の変化に比例した水量を吐水管あるいはシャワヘッドのシャワ板から吐水させながらも節水できる水栓用節水部材およびシャワ用節水部材を提供することを目的としている。
【０００６】
【課題を解決するための手段】
上記目的を達成するために、この発明の水栓用節水部材は、水栓本体に接続される吐水管の上流口の内部に嵌込まれる樹脂製の水栓用節水部材であって、有底筒状で、下流側に底部が位置するよう前記上流口の内部に嵌込まれ、前記上流口の上流端面に係止される外向きフランジを上流端に有するとともに、前記上流口の内周面に当接する環状突出部を胴の外周に円周方向に沿う形で有し、更に、水栓本体の流出流路を吐水管の吐水流路に連通させるとともに、前記吐水流路の吐水流量を前記流出流路の流出流量より減少させる複数の連通孔を前記底部に有し、前記複数の連通孔の開口面積の合計が前記底部の面積の０．３倍よりも大きくて０．８倍よりも小さく、また、前記底部から前記外向きフランジ側に向けて立設され、頂部が前記環状突出部および前記外向きフランジ間に位置するつまみ片を有することを特徴とする。
【０００７】
この発明における連通孔の数は、各連通孔の開口面積Ｓ1 ，Ｓ2 ，Ｓ3 ，Ｓ4 …と底部の面積Ａに依存する。比較例として、吐水量に支障はきたさないが節水効果は得られない開口面積Ｓ（＜Ａ）を持った一つの連通孔を底部に穿設した場合を考える。この比較例では節水効果は得られない。しかし、この発明では、例えば開口面積Ｓ1 ，Ｓ2 ，Ｓ3 およびＳ4 （Ｓ＝Ｓ1 ＋Ｓ2 ＋Ｓ3 ＋Ｓ4 ）をそれぞれ有する、前記一つの連通孔より小面積の４個の連通孔を底部に穿設すると節水効果を得ることができる。そして、Ｓ＝Ｓ1 ＋Ｓ2 ＋Ｓ3 ＋Ｓ4 なので、吐水量に支障はきたすことはない。そして、基準となる前記一つの連通孔の開口面積Ｓは、０．３×Ａ＜Ｓ＜０．８×Ａが好ましい。
【０００８】
また、この発明は別の観点から、継手を介してシャワホースに接続されるシャワヘッドの上流口の内部に嵌込まれる樹脂製のシャワ用節水部材であって、有底筒状で、下流側に底部が位置するよう前記上流口の内部に嵌込まれ、前記上流口の上流端面に係止される外向きフランジを上流端に有するとともに、前記上流口の内周面に当接する環状突出部を胴の外周に円周方向に沿う形で有し、更に、シャワホースの流出流路をシャワヘッドの吐水流路に連通させるとともに、前記吐水流路の吐水流量を前記流出流路の流出流量より減少させる複数の連通孔を前記底部に有し、前記複数の連通孔の開口面積の合計が前記底部の面積の０．３倍よりも大きくて０．８倍よりも小さく、また、前記底部から前記外向きフランジ側に向けて立設され、頂部が前記環状突出部および前記外向きフランジ間に位置するつまみ片を有することを特徴とするシャワ用節水部材を提供する。

BACKGROUND OF THE INVENTION
The present invention relates to a water saving member for a faucet and a water saving member for a shower.
[0002]
[Background Art and Problems to be Solved by the Invention]
As shown in FIG. 7, for example, from the water discharge pipe 72 connected to the faucet body 71, the amount of water is normally discharged in proportion to the change in the water pressure on the faucet body side. Will increase. On the other hand, a water-saving effect can be obtained by providing a constant flow valve at the connecting portion between the faucet body 71 and the water discharge pipe 72 so that the same amount of water is always discharged from the water discharge pipe 72 even if the water pressure on the faucet body changes. However, a faucet water-saving member that can save water while discharging water from the water discharge pipe in proportion to the change in water pressure on the faucet body side is desired.
[0003]
Further, as shown in FIG. 8, the constant flow valve for discharging water from the shower plate 82 attached to the water discharge port 83 of the shower head 81 is always used as the shower head 81 and the shower hose 82 even if the water pressure on the shower hose side changes. However, it is desirable to provide a water-saving member for shower that can save water while discharging water from the shower plate 82 in proportion to the change in water pressure on the shower hose side.
[0004]
Moreover, by reducing than the number of water discharge holes provided in the shower plate normal, although there is a shower which is to be water saving, shower which can save water without the scores reduce the number of water discharge holes of the shower plate is desired .
[0005]
The present invention has been made in view of the above problems, and is a water-saving member for faucets that can save water while discharging water from a water discharge pipe or a shower plate of a shower head in proportion to the change in water pressure on the faucet body side or shower hose side. And it aims at providing the water-saving member for showers.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, a water-saving member for faucets of the present invention is a water-saving member for water faucets made of resin that is fitted inside an upstream port of a water discharge pipe connected to a faucet body, and has a bottom. It is tubular and has an outward flange fitted at the upstream end of the upstream port so that the bottom is located on the downstream side and locked to the upstream end surface of the upstream port, and the inner peripheral surface of the upstream port An annular projecting portion that is in contact with the outer periphery of the body along the circumferential direction, and further, the outlet flow passage of the faucet body is communicated with the water discharge passage of the water discharge pipe, and the water discharge flow rate of the water discharge passage is a plurality of communication holes Ru is lower than the outflow flow rate of the outflow channel is closed on the bottom, 0.8 times the sum of the opening areas of the plurality of communication holes is greater than 0.3 times the area of the bottom Smaller than the bottom, and is erected from the bottom toward the outward flange, and the top is the ring. Characterized in that it has a knob piece located between the projecting portion and the outwardly flange.
[0007]
The number of communication holes in the present invention depends on the opening areas S 1 , S 2 , S 3 , S 4 . As a comparative example, let us consider a case where one communicating hole having an opening area S (<A) that does not impede water discharge but does not provide a water saving effect is formed at the bottom. In this comparative example, the water saving effect cannot be obtained. However, in the present invention, for example, four communication holes each having an opening area S 1 , S 2 , S 3 and S 4 (S = S 1 + S 2 + S 3 + S 4 ) having a smaller area than the one communication hole. A water-saving effect can be obtained by drilling at the bottom. Since S = S 1 + S 2 + S 3 + S 4 , there is no problem with the amount of water discharged. The opening area S of the one communication hole serving as a reference is preferably 0.3 × A <S <0.8 × A.
[0008]
Further, from another viewpoint, the present invention is a resin-made water-saving member for shower that is fitted into an upstream port of a shower head connected to a shower hose through a joint, and has a bottomed cylindrical shape and is provided downstream. An annular projecting portion that is fitted into the upstream port so that the bottom portion is located and has an outward flange that is engaged with the upstream end surface of the upstream port at the upstream end, and that contacts the inner peripheral surface of the upstream port. It has a shape along the circumferential direction on the outer periphery of the trunk, and further, the discharge flow path of the shower hose is connected to the discharge flow path of the shower head, and the discharge flow rate of the discharge flow path is smaller than the discharge flow rate of the discharge flow path. It has a plurality of communication holes Ru is in the bottom, smaller than greater than 0.3 times 0.8 times the area of total the bottom of the opening area of the plurality of communication holes, also, from the bottom It is erected toward the outward flange side and There is provided a shower for water conservation member characterized by having the tab located between the annular projection and the outward flange.
