Description

【0001】
【発明の属する技術分野】
本発明は、流水に光で色付けをする照明付き蛇口取付けユニット、特に水流量に応じて発光色を変化させることが可能な照明付き蛇口取付けユニットに関する。
【0002】
【従来の技術】
水道蛇口は、蛇口本体を水道管に連結し、蛇口のバルブ部に設けたコマの位置をバルブ部に螺合させたハンドルによって操作することにより蛇口内の流路を制御し水流の開閉や水量の調節を行なうものである。
【0003】
従来、こうした蛇口には、多孔板を取り付けて水をシャワー状にしたり、水泡器を取り付けて水泡を発生させたり、あるいは、浄水器を取り付けて浄化することがあるが、いずれも機能に基づいて水流の状態や成分を変化させるものである。特許文献1には、放液管内に光ファイバを用いて光線を導入し放出液を照明する装置が記載されているが、放液管の工事が必要であり、簡単に既存の施設に付加し得るものではない。また、光源の点灯と流水が無関係に行なわれており両者を関連付けるものではない。
【0004】
また、従来、蛇口に装置を付加して節水を行なおうとした場合は、上記のコマをいわゆる「節水コマ」に置き換えて用いることが多い。節水コマは、通常のコマに比べて下部の突出が大きくなっており、ハンドルを開放向きに回した場合でも流路の開きが小さくなる。このため節水が行なわれる(例えば、特許文献2等)。しかし、節水コマは要するに水の出を悪くすることにより節水するものであり、飲食店等の顧客向け施設(洗面所等)で用いた場合は顧客に悪印象を与えかねない。

【0006】
【発明が解決しようとする課題】
このように、蛇口は、日常利用する機会が多く、また、デパートや飲食店では顧客が直接に接する施設であるにも拘わらず、アメニティ性(快適さをもたらし、あるいは増大させる性質)は乏しい。本発明は、従来の水道蛇口にはないアメニティ性をもたせた蛇口を提供することを目的とする。また、本発明は、例えば、出水量を機械的に制限するのではなく利用者自身に節水を促すような蛇口を提供することを目的とする。
【0007】
【課題を解決するための手段】
本発明者は、水道蛇口に高輝度発光ダイオード等の発光体を取り付け、水流が発生した際に発光体を光らせることにより蛇口から出る水に光で色づけすることに成功した。また、この照明付き蛇口取付けユニットにおいて、水量変化に応じて上記発光色を変化させれば、利用者に対して水の無駄使いを認識させ、自発的に節水を行なわせ得ることを認識し、本発明を完成した。
【0008】

[10] 前記1〜8のいずれかに記載の照明付き蛇口取付けユニットを一体に含む照明機能付き蛇口。
【0011】
【発明の実施の形態】
以下、本発明の照明付き蛇口取付けユニット(以下、蛇口取付けユニット)について説明する。
【0012】
図1に本発明の第1の態様における蛇口取付けユニット10を示す。
蛇口取付けユニット10は、ハウジング14内に、回転翼16、小型発電機18及び発光手段20からなる発光ユニット22を含んでなる。
ハウジング10は概ね円筒形または鐘状で、内部に管路24を有し、通常はポリエチレン、ポリプロピレン、塩化ビニル等の透明樹脂製である。ハウジング10は上部にはアダプター12を備えている。アダプター12は蛇口1に取り付けて流水を取り入れための孔13を有しており、蛇口取付けユニット10を蛇口に取り付けた際に蛇口先端の外周から水漏れしないように、通常、弾性材料で構成され蛇口外周に密着する。あるいはアダプター12は、取付けユニットの残りの部分にねじ止めされ得る構造で、ねじ止めの際に前記孔13の径が縮小するキャップ状部材でもよい。これらのアダプター12の構成は、一般に簡易浄水器等で用いられているものが本発明でも同様に利用できる。
【0013】
ハウジング14内には回転翼16を上側に向けて発光ユニット22が装入されている。発光ユニット22は回転翼16、発電機18及び発光手段20を含み、回転翼16とその軸の一部を除いて樹脂ケース(図中、破線で示す。)内に封入したものである。発光ユニット22は好ましくは管路24中に固定される。これは、例えば、ハウジング14の内壁から(例えば、図1の紙面に載るように)管路の軸に平行なフランジを設け、これを上記樹脂ケースと連結すればよい。なお、発光ユニット22の固定方法は任意であり、例えば、管路内に管路の軸に直交して透かし板を設け、これに発光ユニット22を嵌め込むものでもよい。
【0014】
蛇口を開いた場合、本発明の蛇口取付けユニット10には、アダプター12の孔13を通して流水が流入する。これはまず回転翼16に突き当たってこれを回転させ、ハウジング内壁と上記樹脂ケースの間の空隙を通りハウジング下部の流出孔26から放水される。
【0015】
回転翼16の回転はその軸を通して発電機18に伝達され、ここで軸回転の運動エネルギーは電気エネルギーに変換される。回転翼16の形状は図示するようにプロペラ状でもよいが、水流から回転運動を生じるものであればどのような構造でもよい。発電機18は市販の小型モーターを利用することができる。発電機18で生じた電力は配線部19を介して発光手段20に伝えられて発光が実現する。配線部19は好ましくは防水のため、発電機18や発光手段20の端子とともにケースに封入されている。後述のスイッチング回路等をこの内部に設けてもよい。
【0016】
一方、回転翼16の回転により流水は細分されて管路24の内壁に叩きつけられ、また、管路24は流入孔13と流出孔26が狭く内部が広がった形状となっているのでハウジング内、特にその下部で流水は空気と混合して気泡を含んだ水として放出される。このため、発光手段20から直下に向けて照射された光を散乱して、発光手段20の発光色に染まったように光を放つ。
発光手段は特に限定されないが、流水を十分な強度で照明するために高輝度LEDを用いることが好ましい。高輝度LEDは、各社から市販されており、赤、緑、青、白色等多数の色彩のものが利用可能である。
【0017】
LEDはそのままでもよいが、適当な光学系と組み合わせてもよい。例えば、狭角レンズを用いることにより、蛇口から流出する水流内に効率的に光を照射することができる。あるいは逆に広角レンズを用いることにより、蛇口取付けユニット下部を光で色付かせることも可能である。こうしたレンズはLEDと一体に成形されているものでもよい。
【0018】
本発明の好ましい態様では、LEDを多色発光LEDとする。これは複数のLEDを組み合わせる等して発光色を多色化したものである。
上述のように、本発明の蛇口取付けユニットを取り付けて流水状態にすると、管路24内を通る水流が回転翼16を回転させて小型発電機18内の回転子(図示していない。)を回転させる。その結果、発電機18は起電力を生じて発光手段(LED)20に電気エネルギーを付与する。従って、単位時間当たりの流水量が増すとにこれに応じて起電力も増大する。回路内の抵抗を一定とすればLEDに印加される電流が増大することになる。
【0019】
従って、印加電流または電圧について複数(例えば、第1及び第2)の閾値が存在し、第1の閾値以上第2の閾値未満では第1の色が発光し、第2の閾値以上では第2の色が発光する多色発光LEDを用いれば水量の少ない場合と多い場合とで発光色を変化させることができる。あるいは、端子の切替えにより発光色が変化したり制御信号線への入力により発光色が変化する場合は、例えば、トランジスターを含む慣用のスイッチング回路を利用して発電機電圧また電流に応じて端子を切替え、あるいは制御信号を発して発光色を変えてもよい。
【0020】
例えば、洗面所等では一般にそれ程多くの水量を必要とするものではないが、多くの場合、多量に水を流した方が清潔であるような印象を与える。本発明では、利用者に対して、適正な水量はこの色ですよ、という旨の掲示等をして利用者に自発的に水量調節させることができる。また、一般に人間は白や寒色系の色を無機的に、暖色系の色を有機的に感ずる傾向があるので、水量が適切である場合は白や青や緑を発光し、水量が過剰である場合は黄色や赤い光を発するなどすれば、利用者は少ない水量でも清潔な印象を得たり、あるいは多い水量にした場合は必ずしも清潔な印象を得なくなるので自ずから使用水量が低減する。
【0021】
図2に本発明の第2の態様における蛇口取付けユニット30を示す。
これは図1と同様なアダプター32を有するハウジング34内に管路44を設け、その内部にスイッチ36、電池38及び発光手段40を含む発光ユニット42を設けたものである。好ましくは、図1の場合と同様に発光ユニット42は樹脂ケース(破線で示す。)に封入して管路44内に固定する。
【0022】
蛇口を開いた場合、本発明の蛇口取付けユニット30には、アダプター32の孔33を通して流水が流入する。これはまずスイッチ36に突き当たってこれに圧力を与える。スイッチ36は圧力を加えられてこれにより電池38からと発光手段40をつなぐ回路が導通して発光手段40が発光する。水はハウジング内壁と上記樹脂ケースとの間の空隙を通りハウジング下部の流出孔46から放水される。
【0023】
スイッチ36の押し下げによる回路の開閉は、スイッチ36を感圧スイッチにすることで実現できる。感圧スイッチは、例えば、ゴムなど弾性材料で形成した袋状部材とし、空隙を隔てて対面する内側両面にそれぞれ導電体を設けることで構成できる。感圧スイッチに力が加わると弾性材料が変形してこれらの導電体が接触し導通する。このような感圧スイッチは公知であり市販されている。この場合、表面積の大きな圧力感知部と表面積の小さな作動部を有する補助手段を感圧スイッチの上部に設ければ、水流による圧力が比較的小さい場合でも確実にスイッチを作動させることができる。
【0024】
弾性材料の内面に互いに絶縁された2対の導電体を設け、それぞれの導電体が設けられた部分の肉厚を部分的に変えるなどによりスイッチ面状に可撓性の異なる領域を設けてもよい。水流量が少ないときは可撓性の高い部分が凹んで第1のスイッチが入り、水流量が増すと可撓性の低い部分も凹んで第2スイッチが入る。これを上述の多色発光LEDと組み合わせれば、上記の発電機を用いた場合と同様に、水流量に応じて発光色を変化させることができる。
【0025】
水流量に応じたスイッチングは上記の方法に限定されるものではない。
例えば、図3はハウジング等は図2と同様であるが、上部の閉鎖された筒状ケース62内にスイッチ部材58及び発光手段60からなる発光ユニットを設けたものである。発光ユニットの上面はバネ部材63で筒状ケース62の上部に接続されており、筒状ケース内部を上下に可動である。また、筒状ケース62内は下端に開口を有し、発光手段60がこの開口内を摺動することができる。スイッチ部材58は第1の端子対a1、a2と第2の端子対b1、b2をその外面に有している。一方、筒状ケース内部には導電帯59が周状に設けられている。
【0026】
ここで、スイッチ部材58は内部に電池と接続回路、例えば、端子a1→電池負極→電池内部→電池正極→青色LEDカソード→青色LED→青色LEDアノード→端子a2のように電池とLEDを挟んで開放された回路を含んでいる。スイッチ部材58には、例えば、端子b1→電池負極→電池内部→電池正極→赤色LEDカソード→赤色LED→赤色LEDアノード→端子b2のように電池とLEDを挟んで開放された別の回路も含んでいる。
【0027】
水流量がゼロの場合、発光ユニットはバネ部材63により筒状ケースの上端に支持され、この場合、前記端子対a1とa2との間及び第2の端子対b1とb2との間はいずれも絶縁されているのでいずれの発光ダイオードも点灯しない。
蛇口を開いて水を流すと、発光ユニットは水流に引きずられて下方に下がる。この結果、第1の端子対a1、a2がいずれも周状導電帯59に接する位置まで下がると端子a1とa2間が導通状態となる。従って、端子a1とa2の導通により、例えば、端子a1→周状導電体→端子a2→電池負極→電池内部→電池正極→青色LEDカソード→青色LED→青色LEDアノード→端子a1のような閉回路を形成し、青色LEDが発光する。さらに水流が増すと発光ユニットはさらに下方に引きずられて第1の端子対a1、a2がいずれも周状導電帯59から外れるとともに第1の端子対b1、b2がいずれも周状導電帯59に接する位置まで下がる。この結果、端子b1とb2間の導通により、例えば、端子b1→周状導電体→端子b2→電池負極→電池内部→電池正極→赤色LEDカソード→赤色LED→赤色LEDアノード→端子b1のような閉回路を形成し、赤色LEDが発光する。水量が減ると赤色LEDが消えて青色LEDが点灯し、さらに水量が減るといずれのLEDも消灯する。
【0028】
なお、図3では便宜上、前記端子対a1、a2とb1、b2はいずれも例えば、発光ユニットの外周面に好ましくはその中心から見て180度隔てた位置に設けているが、これらの端子は異なる位置、例えば、発光ユニットの軸方向から見てa1、b1、a2及びb2が90度ずつ離れるように設けることが好ましい。また、周状導電体の幅や端子対間の距離等は目的やバネの弾性等に応じて変更できる。さらにまた、端子a1、b1、a2及びb2は回路の開閉が適切に行なわれればよいのであり、回路内のどの位置に設けるかは任意である。
【0029】
あるいは、この態様でバネ部材を省略し、無水量状態では発光ユニットが自重により筒状ケース62内の下端に位置する構成とし、水流がハウジング54から出る際の狭縊部の構造を変更して水流の圧力により発光ユニットが押し上げられるようにしてもよい。この場合、周状導電体59は筒状ケース62の上部に設ける。水流が増すと発光ユニットの上側に設けた端子間b1とb2が導通し、さらに増すと下側面に設けた端子間a1とa2が導通するようになる。なお、この構成では端子a1とa2を赤色LEDに端子b1とb2を青色LEDに接続することにより、低水量で青色が高水量で赤色が発光することになる。
なお、上記のいずれの構造でも、電池は市販の小型電池、好ましくはボタン電池を用いる。
【0030】
以上、本発明の実施形態について具体的に説明してきたが、本発明の範囲内において、様々な変形や修正が可能であり、これらも本発明に含まれる。例えば、上記第1の態様においては軸方向の水流を受けることにより回転する回転翼を用いたが、羽根車(水車)の羽根に水流が当たり回転するようにしてもよいし、この場合、発電機はハウジングの側面に突き出すように配置してもよい。このようにすれば、本発明の蛇口取付けユニットの長さ方向の寸法を短くすることができる。
【0031】
また、上記第2の実施態様の変形例では、発光ユニットに突起状端子を設け、円筒状ケース内面に周状導体を設けたが、発光ユニットの外表面に周状導体を設け、円筒状ケース内面に突起状端子を設けてもよい。水流量の大小に応じて発光ユニットの位置が端子接続位置の変化をもたらすものであれば、これ以外の任意の構成を取ることができる。バネ部材は例えば抗菌性材料でできたスポンジ等でよい。また、実施態様2の変形例では接点間抵抗値が振動する可能性があるが、これを積極的に用いて炎がゆらめくような効果を出してもよいし、あるいは、適当な平滑回路を内在させてちらつきをなくしてもよい。
【0032】
また、以上の説明では水流量に応じて発光色が変化する態様を説明してきたが、水流量に応じて発光色が変化する態様に代えて、例えば、温度センサーを設け(例えば、図2の態様でスイッチ36に加えてあるいはスイッチ36に代えて温度センサー部を設ける。)、水温(例えば、冷水、温水)に応じて発光色を変化させてもよい。
【0033】
さらに、発光ユニットをハウジングへの嵌め込み式とし流入口から取り出せるようにするか、ハウジングの一部(例えば、底板)を取り外せるか開放可能としてハウジングから発光ユニットを取り出せるようにしてもよい。これにより、例えば、上記第1の態様(エネルギー自給式)では回転翼等の交換や発光ユニット表面の洗浄、上記第2の態様(電池式)では電池の交換が可能となる。あるいは、配線の一部をハウジングを貫いて設け電池のみをハウジング外部に、好ましくは電池交換の容易な電池ケースに入れて取り付けるか、外部電源と接続してもよい。
また、これまで説明してきた照明付き蛇口取付けユニットを蛇口末端に一体化して照明機能付き蛇口としてもよい。この場合は、例えば、蛇口末端に開閉口を設けてそこから発光ユニットを出し入れできるようにすることが好ましい。
【0034】
【実施例】
2色発光ダイオードを使用し、上記実施態様1、2及びその変形例に即して蛇口取付けユニットを製作し、水流を流したところ、実施態様1と実施態様2の変形例では流水量に応じて、赤色と青色が流水を鮮やかに照明する効果が実現できた。実施態様2の変形例では、直接に発光部を観察した場合には光量に若干の変化が見られたが、むしろ揺らぎのような効果があった。
また、比較的低照度の照明を用いたレストルームの蛇口に本発明の2色発光照明付きユニットを設置し、その効果を試験した(装置構成自体はわからないように実験した。)ところ、快適で気分的に安らぐとの意見が多数を占め、青色ないし緑色の発光を伴う場合はそうでない場合に比較して、水道使用時の最大流量が有意に減少した。
【0035】
【発明の効果】
以上、説明してきたように、本発明の照明付き蛇口取付けユニットによれば、従来無機的な道具に過ぎなかった蛇口内に発光手段を設けることにより流水を照明して、癒し効果などのアメニティ性を付与することができる。また、本発明の蛇口は水流による発電や小型電池が利用できるためコンパクトな構成が可能である。さらに、特に多色発光型では流水量に応じて発光色を変化させることができるので、種々の効果、特に節水促進効果を実現することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an illuminated faucet mounting unit for coloring running water with light, and more particularly to an illuminated faucet mounting unit capable of changing the emission color according to the flow rate of water.
[0002]
[Prior art]
The tap is connected to the main body of the tap with a water pipe, and the position of the top provided on the valve of the tap is operated by a handle screwed to the valve to control the flow path inside the tap to open and close the water flow and to control the water flow. It is to adjust.
[0003]
Conventionally, such faucets may be fitted with a perforated plate to make the water into a shower, a water bubbler may be attached to generate water bubbles, or a water purifier may be attached to purify the water. It changes the state and components of the water flow. Patent Document 1 discloses a device for illuminating a discharged liquid by introducing a light beam into a liquid discharge tube using an optical fiber. However, construction of the liquid discharge tube is required, and the device is easily added to an existing facility. You don't get it. In addition, the lighting of the light source and the flowing water are performed independently, and the two are not related.
[0004]
Further, conventionally, when a device is added to a faucet to save water, the above-mentioned frame is often replaced with a so-called “water saving frame”. The lower part of the water-saving coma has a larger protrusion than the normal coma, and the opening of the flow path becomes smaller even when the handle is turned in the opening direction. For this reason, water is saved (for example, Patent Document 2). However, the water-saving top is to save water by making water flow worse, and when used in a facility for customers (a washroom or the like) such as a restaurant, it may give a bad impression to the customer.
[0005]

Japanese Patent Application Laid-Open No. 8-254519 [Patent Document 2]
JP-A-2001-049708
[Problems to be solved by the invention]
As described above, the faucet has many opportunities for daily use, and in a department store or a restaurant, despite being a facility directly contacted by customers, amenity (a property of providing or increasing comfort) is poor. SUMMARY OF THE INVENTION An object of the present invention is to provide a faucet having amenities that cannot be provided by a conventional water tap. Another object of the present invention is to provide, for example, a faucet that encourages the user to save water without mechanically limiting the amount of water discharged.
[0007]
[Means for Solving the Problems]
The present inventor has succeeded in coloring water coming out of the faucet with light by attaching a light-emitting body such as a high-brightness light-emitting diode to the water tap and illuminating the light-emitting body when a water stream is generated. Also, in this illuminated faucet mounting unit, if the emission color is changed in accordance with the change in the amount of water, the user can recognize wasteful use of water and recognize that the user can voluntarily save water.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the illuminated faucet attachment unit (hereinafter, faucet attachment unit) of the present invention will be described.
[0012]
FIG. 1 shows a faucet mounting unit 10 according to a first embodiment of the present invention.
The faucet mounting unit 10 includes a light emitting unit 22 including a rotor 16, a small generator 18, and a light emitting means 20 in a housing 14.
The housing 10 is generally cylindrical or bell-shaped, has a conduit 24 inside, and is usually made of a transparent resin such as polyethylene, polypropylene, or vinyl chloride. The housing 10 has an adapter 12 on the upper part. The adapter 12 has a hole 13 attached to the faucet 1 for taking in flowing water, and is usually made of an elastic material so that water does not leak from the outer periphery of the faucet tip when the faucet attachment unit 10 is attached to the faucet. Adhere to faucet periphery. Alternatively, the adapter 12 may be a cap-shaped member that has a structure that can be screwed to the rest of the mounting unit, and the diameter of the hole 13 is reduced when the screw is screwed. The configuration of these adapters 12 that is generally used in a simple water purifier or the like can be similarly used in the present invention.
[0013]
A light emitting unit 22 is installed in the housing 14 with the rotating blades 16 facing upward. The light emitting unit 22 includes the rotor 16, the generator 18, and the light emitting means 20, and is sealed in a resin case (shown by a broken line in the drawing) except for the rotor 16 and a part of its shaft. Lighting unit 22 is preferably fixed in conduit 24. For example, a flange parallel to the axis of the conduit may be provided from the inner wall of the housing 14 (for example, as shown on the paper surface of FIG. 1) and connected to the resin case. The method of fixing the light emitting unit 22 is arbitrary. For example, a watermark plate may be provided in the pipeline perpendicular to the axis of the pipeline, and the light emitting unit 22 may be fitted into the watermark plate.
[0014]
When the faucet is opened, flowing water flows into the faucet mounting unit 10 of the present invention through the hole 13 of the adapter 12. This first hits the rotary wings 16 and rotates them, so that water is discharged from an outflow hole 26 at the lower part of the housing through a gap between the inner wall of the housing and the resin case.
[0015]
The rotation of the rotor 16 is transmitted through its shaft to a generator 18 where the kinetic energy of the shaft rotation is converted to electrical energy. The shape of the rotary wing 16 may be a propeller shape as shown in the figure, but may be any structure as long as the rotary motion is generated from a water flow. The generator 18 can use a commercially available small motor. The electric power generated by the generator 18 is transmitted to the light emitting means 20 via the wiring section 19 to realize light emission. The wiring portion 19 is preferably enclosed in a case together with terminals of the generator 18 and the light emitting means 20 for waterproofing. A switching circuit and the like to be described later may be provided in the inside.
[0016]
On the other hand, the running water is subdivided by the rotation of the rotary wings 16 and is beaten against the inner wall of the conduit 24. Further, since the conduit 24 has a shape in which the inflow hole 13 and the outflow hole 26 are narrow and the inside is wide, the inside of the housing, Especially at the lower part, the running water is mixed with air and released as water containing bubbles. Therefore, the light emitted from the light emitting means 20 is scattered directly downward, and the light is emitted as if the light emitted by the light emitting means 20 was dyed.
The light emitting means is not particularly limited, but it is preferable to use a high-brightness LED to illuminate the flowing water with a sufficient intensity. High-brightness LEDs are commercially available from various companies, and many colors such as red, green, blue, and white can be used.
[0017]
The LED may be used as it is, or may be combined with an appropriate optical system. For example, by using a narrow-angle lens, it is possible to efficiently irradiate light into a water flow flowing out of a faucet. Alternatively, by using a wide-angle lens, the lower part of the faucet attachment unit can be colored with light. Such a lens may be formed integrally with the LED.
[0018]
In a preferred embodiment of the present invention, the LED is a multicolor LED. This is a multi-color emission by combining a plurality of LEDs.
As described above, when the faucet attachment unit of the present invention is attached to make the water flow state, the water flow passing through the pipeline 24 rotates the rotary wings 16 to rotate the rotor (not shown) in the small generator 18. Rotate. As a result, the generator 18 generates an electromotive force to apply electric energy to the light emitting means (LED) 20. Therefore, as the amount of flowing water per unit time increases, the electromotive force increases accordingly. If the resistance in the circuit is constant, the current applied to the LED will increase.
[0019]
Therefore, there are a plurality of (for example, first and second) thresholds for the applied current or the voltage, and the first color is emitted when the threshold is equal to or more than the first threshold and less than the second threshold, and is equal to or greater than the second threshold. If a multi-color light emitting LED that emits light of the above color is used, the light emission color can be changed depending on whether the amount of water is small or large. Alternatively, when the emission color changes due to the switching of the terminal or the emission color changes due to the input to the control signal line, for example, the terminal is changed according to the generator voltage or current using a conventional switching circuit including a transistor. The light emission color may be changed by switching or by issuing a control signal.
[0020]
For example, a lavatory or the like generally does not require a large amount of water, but in many cases, giving a large amount of water gives an impression that it is cleaner. In the present invention, the user can voluntarily adjust the amount of water by, for example, notifying the user that the appropriate amount of water is this color. Also, generally, humans tend to feel white or cool colors inorganically and warm colors organically, so if the amount of water is appropriate, white or blue or green light is emitted, and if the amount of water is excessive, In some cases, if yellow or red light is emitted, the user can obtain a clean impression even with a small amount of water, or if a large amount of water is used, the user will not necessarily obtain a clean impression, so that the amount of water used naturally decreases.
[0021]
FIG. 2 shows a faucet mounting unit 30 according to a second embodiment of the present invention.
In this embodiment, a conduit 44 is provided in a housing 34 having an adapter 32 similar to that shown in FIG. 1, and a light emitting unit 42 including a switch 36, a battery 38, and a light emitting means 40 is provided therein. Preferably, the light emitting unit 42 is sealed in a resin case (shown by a broken line) and fixed in the pipe 44 as in the case of FIG.
[0022]
When the faucet is opened, flowing water flows into the faucet attachment unit 30 of the present invention through the hole 33 of the adapter 32. This first strikes the switch 36 and applies pressure to it. The switch 36 is pressurized, whereby the circuit connecting the battery 38 and the light emitting means 40 is turned on, and the light emitting means 40 emits light. The water passes through a gap between the inner wall of the housing and the resin case and is discharged from an outflow hole 46 at a lower portion of the housing.
[0023]
Opening and closing of the circuit by depressing the switch 36 can be realized by making the switch 36 a pressure-sensitive switch. The pressure-sensitive switch is, for example, a bag-shaped member made of an elastic material such as rubber, and can be configured by providing conductors on both inner surfaces facing each other with a gap therebetween. When a force is applied to the pressure-sensitive switch, the elastic material is deformed and these conductors come into contact and conduct. Such pressure-sensitive switches are known and commercially available. In this case, if an auxiliary means having a pressure sensing unit having a large surface area and an operating unit having a small surface area is provided above the pressure-sensitive switch, the switch can be reliably operated even when the pressure due to the water flow is relatively small.
[0024]
Even if two pairs of conductors insulated from each other are provided on the inner surface of the elastic material, and the thickness of the portion provided with each conductor is partially changed, a region having different flexibility is provided on the switch surface. Good. When the water flow rate is low, the first switch is turned on when the high flexibility portion is recessed, and when the water flow rate is increased, the second switch is turned on also when the low flexibility portion is also recessed. If this is combined with the above-mentioned multicolor light emitting LED, the luminescent color can be changed according to the water flow rate, as in the case of using the above generator.
[0025]
Switching according to the water flow rate is not limited to the above method.
For example, in FIG. 3, the housing and the like are the same as in FIG. 2, but a light emitting unit including a switch member 58 and light emitting means 60 is provided in a closed cylindrical case 62 at the upper part. The upper surface of the light emitting unit is connected to the upper part of the cylindrical case 62 by a spring member 63, and can move up and down inside the cylindrical case. Further, the inside of the cylindrical case 62 has an opening at the lower end, and the light emitting means 60 can slide in the opening. The switch member 58 has a first terminal pair a1, a2 and a second terminal pair b1, b2 on its outer surface. On the other hand, a conductive band 59 is provided circumferentially inside the cylindrical case.
[0026]
Here, the switch member 58 has a battery and a connection circuit inside, for example, the terminal a1 → the battery negative electrode → the inside of the battery → the battery positive electrode → the blue LED cathode → the blue LED → the blue LED anode → the terminal a2 sandwiching the battery and the LED. Includes open circuits. The switch member 58 also includes another circuit opened between the battery and the LED, for example, the terminal b1 → the battery negative electrode → the inside of the battery → the battery positive electrode → the red LED cathode → the red LED → the red LED anode → the terminal b2. In.
[0027]
When the water flow rate is zero, the light-emitting unit is supported on the upper end of the cylindrical case by the spring member 63, and in this case, between the terminal pair a1 and a2 and between the second terminal pair b1 and b2. None of the light emitting diodes are lit because they are insulated.
When the faucet is opened and water flows, the light emitting unit is dragged down by the water flow and descends. As a result, when both of the first terminal pairs a1 and a2 are lowered to positions where they contact the circumferential conductive band 59, the terminals a1 and a2 are brought into a conductive state. Therefore, due to the conduction between the terminals a1 and a2, for example, a closed circuit such as the terminal a1 → circumferential conductor → terminal a2 → battery negative electrode → inside the battery → battery positive electrode → blue LED cathode → blue LED → blue LED anode → terminal a1 Is formed, and the blue LED emits light. When the water flow further increases, the light emitting unit is dragged further downward, so that the first terminal pairs a1 and a2 both come off the circumferential conductive band 59 and the first terminal pairs b1 and b2 both come into the circumferential conductive band 59. Lower to the point where it touches. As a result, due to conduction between the terminals b1 and b2, for example, terminal b1 → circular conductor → terminal b2 → battery negative electrode → inside battery → battery positive electrode → red LED cathode → red LED → red LED anode → terminal b1 A closed circuit is formed, and the red LED emits light. When the amount of water decreases, the red LED turns off and the blue LED turns on, and when the amount of water further decreases, all LEDs turn off.
[0028]
In FIG. 3, for convenience, all of the terminal pairs a1, a2 and b1, b2 are provided, for example, on the outer peripheral surface of the light emitting unit, preferably at positions separated by 180 degrees when viewed from the center thereof. It is preferable that a1, b1, a2, and b2 are provided at different positions, for example, 90 degrees apart from each other when viewed from the axial direction of the light emitting unit. Further, the width of the circumferential conductor, the distance between the terminal pairs, and the like can be changed according to the purpose, the elasticity of the spring, and the like. Furthermore, the terminals a1, b1, a2, and b2 are only required to open and close the circuit appropriately, and the positions in the circuit are arbitrary.
[0029]
Alternatively, in this embodiment, the spring member is omitted, and in the anhydrous state, the light emitting unit is located at the lower end in the cylindrical case 62 by its own weight, and the structure of the narrow portion when the water flow exits the housing 54 is changed. The light emitting unit may be pushed up by the pressure of the water flow. In this case, the circumferential conductor 59 is provided above the cylindrical case 62. When the water flow increases, the terminals b1 and b2 provided above the light emitting unit conduct, and when the water flow further increases, the terminals a1 and a2 provided on the lower surface thereof conduct. In this configuration, by connecting the terminals a1 and a2 to the red LED and the terminals b1 and b2 to the blue LED, blue light is emitted at a low water amount and red light is emitted at a high water amount.
In any of the above structures, a commercially available small battery, preferably a button battery, is used as the battery.
[0030]
Although the embodiments of the present invention have been specifically described above, various changes and modifications are possible within the scope of the present invention, and these are also included in the present invention. For example, in the above-described first embodiment, a rotating blade that rotates by receiving an axial water flow is used. However, the water flow may hit a blade of an impeller (water turbine), and in this case, power generation may be performed. The machine may be arranged to protrude on the side of the housing. By doing so, the length of the faucet attachment unit of the present invention in the length direction can be reduced.
[0031]
In the modification of the second embodiment, the light emitting unit is provided with the protruding terminals and the inner surface of the cylindrical case is provided with the circumferential conductor. However, the outer surface of the light emitting unit is provided with the circumferential conductor, and the cylindrical case is provided. A protruding terminal may be provided on the inner surface. Any other configuration can be adopted as long as the position of the light emitting unit changes the terminal connection position according to the magnitude of the water flow rate. The spring member may be, for example, a sponge made of an antibacterial material. Further, in the modification of the second embodiment, the resistance between the contacts may vibrate, but this may be positively used to produce an effect that the flame fluctuates, or an appropriate smoothing circuit may be provided. The flicker may be eliminated.
[0032]
Further, in the above description, the mode in which the emission color changes according to the water flow rate has been described. However, instead of the mode in which the emission color changes according to the water flow rate, for example, a temperature sensor is provided (for example, FIG. In an embodiment, a temperature sensor unit is provided in addition to or in place of the switch 36.) The emission color may be changed according to the water temperature (for example, cold water or hot water).
[0033]
Further, the light emitting unit may be fitted into the housing so that the light emitting unit can be taken out from the inlet, or a part of the housing (for example, a bottom plate) can be removed or opened so that the light emitting unit can be taken out from the housing. Thus, for example, in the first aspect (energy self-supply type), replacement of a rotor or the like and cleaning of the light emitting unit surface can be performed, and in the second aspect (battery type), replacement of a battery is possible. Alternatively, a part of the wiring may be provided through the housing, and only the battery may be mounted outside the housing, preferably in a battery case where the battery can be easily replaced, or connected to an external power source.
Further, the faucet mounting unit with illumination described above may be integrated with the faucet end to form a faucet with illumination function. In this case, for example, it is preferable to provide an opening and closing port at the end of the faucet so that the light emitting unit can be taken in and out therefrom.
[0034]
【Example】
A two-color light emitting diode was used, and a faucet mounting unit was manufactured according to the first and second embodiments and the modified examples thereof, and a water flow was caused. In the modified examples of the first and second embodiments, according to the amount of flowing water. Thus, the effect of red and blue illuminating the running water vividly was realized. In the modification of the second embodiment, when the light emitting portion is directly observed, a slight change in the light amount is observed, but there is an effect such as a fluctuation.
Further, the unit with the two-color light emitting illumination of the present invention was installed in a faucet of a rest room using illumination of relatively low illuminance, and its effect was tested (experiment was conducted so that the device configuration itself was not understood). Many thought that they felt comfortable, and the maximum flow rate when using water was significantly reduced when blue or green luminescence was involved.
[0035]
【The invention's effect】
As described above, according to the illuminated faucet attachment unit of the present invention, the light emitting means is provided in the faucet, which has conventionally been merely an inorganic tool, to illuminate the running water, thereby providing amenity such as a healing effect. Can be given. Further, since the faucet of the present invention can use power generation by water flow or use a small battery, a compact configuration is possible. Furthermore, in the case of the multicolor emission type, the emission color can be changed in accordance with the amount of flowing water, so that various effects, particularly, an effect of promoting water saving can be realized.
