Description

【０００１】
【発明の属する技術分野】
本発明は、水道水、井戸水等の原水を浄化水に改水する浄水器カートリッジ、及び該浄水器カートリッジが搭載でき該浄水器カートリッジの寿命等の表示及び／又は警報ができる寿命表示器付き浄水器に係るものであり、詳しくはリサイクル可能な浄水器カートリッジと、該浄水器カートリッジのカートリッジ型式（逆取付）、活性炭の寿命、中空糸膜フィルタの寿命、が個別に検出できて、各々の積算値等のデータをはじめ、メッセージ等の各種データ情報を、任意に寿命表示器に表示及び／又は警報（メロディを含む。）させることができる浄水器と、流量センサの流量検出精度改善と、止水弁機能や逆止弁機能等の複合機能が期待できる差圧センサと、等に関する。
【０００２】
【従来の技術】
従来、主流の浄水器カートリッジには、活性炭カートリッジと、中空糸膜フィルタカートリッジと、活性炭＋中空糸膜フィルタカートリッジと、等がある。
細部において、活性炭には粉末状、粒状、球状、繊維状、フエルト状、等の形態があり、中空糸膜フィルタに使用される中空糸にはポリエチレン中空糸、ポリスルホン中空糸、等の材質がある。
通常は活性炭の量（総表面積）や質（銀添、賦活方法、残留塩素分解用有機物除去用、新品リサイクル品）により寿命（例えば、規定〔２ｐｐｍ〕の残留塩素濃度含有の水道水を通過させ、規定〔０．４ｐｐｍ〕の残留塩素濃度含有の浄化水が流出されてきた場合。）が異なる。ここでいう寿命とは活性炭の処理可能な残留塩素（水道水）総量をいう。又、活性炭の不活性化（劣化）特性により使用限界（有効期限寿命）もある。
又中空糸膜フィルタの本数等（孔径、総表面積、断面積）により寿命（例えば、規定〔濁度１０〕の濁度含有の水道水を通過させ、規定〔濁度２〕の濁度含有の浄化水が流出されてきた場合。）が異なる。ここでいう寿命とは中空糸膜フィルタの使用時間でなく、処理可能な濁度（水道水）総量をいう。
【０００３】
参考ではあるが、例えば、有機物、残留塩素、硬度、不純物、異物、濁度、異臭等を除去、改質、改変、改善するための浄化装置（カートリッジ）には、例えば、金属メッシュフィルタ、ゴムメッシュフィルタ、樹脂メッシュフィルタ、不織紙フィルタ、不織布フィルタ、セルローズ繊維フィルタ、ガラス繊維フィルタ、還元性物質、吸着性物質、活性炭、亜硫酸カルシウム、キチンキトサン粉末、シリカゲル、麦飯石等の漢方薬、中空糸膜フィルタ、精密ろ過膜（ＭＦ膜）フィルタ、限外ろ過膜（ＵＦ膜）フィルタ、逆浸透膜（ＲＯ膜）フィルタ、電子交換体、イオン交換体（有機ゼオライト、無機ゼオライト、合成ゼオライト含む。）、イオン交換膜、イオン交換紙、イオン交換繊維、イオン交換樹脂、イオン交換樹脂触媒、オゾン発生装置、磁石（電磁石含む。）、セラミック体（例えば、セラミックボール）、多孔性無機物質、半導体（例えば、樹脂ボール体に二酸化チタンコーティング）等で構成されたもの等があり、さらに、除菌・抗菌・殺菌・微生物抑制剤（例えば、酸化チタン、亜鉛華）等を添加したものもある。
【０００４】
従来、浄水器の種類には、給水管又は給水栓の流出側に取り付けて常時圧力が作用する浄水器Ｉ型（浄水器の流出側に止水機構を設けたもの）と、給水栓の流出側に取り付けて常時圧力が作用しない浄水器II型（浄水器の流出側に止水機構が無いもの）と、等に区分されていた。
そして、水道蛇口に直結する直結型浄水器〔いわゆる槓杆切替栓一体型浄水器で、通常、槓杆切替えで水道水ストレート吐水／水道水シャワー吐水／浄化水吐水が可能である。〕と、水道蛇口に直結する分岐栓から配水される据置型浄水器〔いわゆる分岐栓分離式の据置型浄水器、例えば、ミネラル水生成器、冷水器、アルカリイオン整水器、等が該当する。通常は、分岐栓と据置型浄水器とを給水ホース等で接続して使用し、分岐栓の槓杆切替えで水道水ストレート吐水／水道水シャワー吐水／据置型浄水器への配水が可能である。〕と、等がある。
【０００５】
さて、流量積算値の記憶及び／又は表示の機能を有する流量表示器を搭載する浄水器には、例えば、特開昭６０−９９３８１号公報等で開示されているように、羽根車とカウンタ（流量表示器）とを組合せたもの（メカ式）と、特開平３−２９３０８５号公報等で開示されているように、流量センサと電子制御システムとを組合せたもの（電子式）と、が知られている。
【０００６】
電子制御システムは、例えば、印刷配線基板（印刷配線基板とは一般的にプリント配線板と呼ばれるもので、概要として銅張積層板の銅箔においては電気回路に必要な配線パターンだけをエッチング処理で残し、実装する部品等のリード足形状等に合わせて穿孔し、ソルダーレジスト処理及びシルク文字印刷等を施して完成されるものをいう。製造工程及び手順はメーカにより異なる場合がある。）に電子回路部品の制御マイコン（例えば、８ビット・マイコン、ＲＯＭ、ＲＡＭ等が一体になっているもの。）、外部記憶装置（例えば、ＲＡＭ、ＥＥＰＲＯＭ、フラッシュメモリ等）、抵抗、コンデンサ、トラジスタ、ダイオード、ＩＣ等を実装した印刷配線基板ユニットと、操作スイッチ類と、ＬＥＤランプ・ＬＣＤ等の表示装置及び／又はブザー・スピーカ等の警報装置と、等で構成される場合が多い。
【０００７】
流量センサは、回転羽根支持軸を有する前段整流羽根と、磁石を内蔵する回転羽根と、該回転羽根と水中摺動する後段整流羽根と、からなる流量検出体と、該流量検出体の外周部近傍に接離動可能に別設される磁気検出装置と、からなる分離型羽根車式流量センサ、又は、回転羽根支持軸を有する前段整流羽根と、磁石を内蔵する回転羽根と、該回転羽根と水中摺動する後段整流羽根と、該磁石の外周部近傍に並設され接離動不可能な磁気検出装置と、からなる一体型羽根車式流量センサ、が主流である。
該磁気検出装置（磁性感動素子）には、例えば、リードスイッチ、ホールＩＣ、磁気抵抗、コイル等があり、通常はガラス管封入形リードコンタクト式の常時開路接点（ａ接点又はメーク接点ともいう。）のリードスイッチが多用されている。コスト的にはホールＩＣが有利な場合もある。
【０００８】
前記羽根車式流量センサは、浄水器内を通過する水（原水又は浄化水）の瞬間流量等を検出するために搭載するものであり、その瞬間流量検出信号（回転する磁石の磁界がリードスイッチに影響を及ぼし、リードスイッチ接点が短絡状態になったり開放状態になったりすることにより、例えば、電気抵抗部品等でプルアップしている電気回路を採用した場合は、パルス信号として出力される。）に基づきマイコンで流量積算値等を演算処理して算出し、ＲＡＭ（ＥＥＰＲＯＭ、フラッシュメモリ等でも良い。）等にそのデータを記憶させ、該流量積算値と比較値（寿命判定値、寿命初期値等で、予めＲＯＭ、ＥＥＰＲＯＭ等に登録されている。）とを比較して、該比較値を超過した場合は、例えば、ランプやブザー等で浄水器カートリッジ等の交換時期を使用者に報知する等の判断に用いられる重要な要素部品である。
そして、流量センサを浄水器カートリッジより下方部に設置する場合は、流量センサ内に空気が通過しても暫くすれば水（原水又は浄化水）で充満されて、精度の良い流量検出ができるものである。
【０００９】
ところで、流量センサ以外で、水の特性（例えば、水圧）を検出するセンサを用いた（応用した）技術には、例えば、実開平３−１１９４９５号公報等で開示されているように、浄水器カートリッジの流入口部の水圧Ｈと、浄水器カートリッジの流出口部の水圧Ｌと、の圧力差を検出する圧力センサ（圧力スイッチとしての利用。）で、電源を投入できる水処理装置が知られている。
又、特開平５−１９２６５４号公報等で開示されているように、２つの圧力センサで中空糸膜フィルタ等の圧力損失等を検出し寿命判定している浄水器が知られている。
【００１０】
例えば、登録実用新案第３０１２１５２号公報等で開示されているように、浄水器カートリッジに磁石等を埋設（一体成形すると良い。）し、又印刷配線基板ユニットに磁気検出装置を搭載しておけば、該浄水器カートリッジを着脱（交換）すると、該磁気検出装置が或る信号を発信して印刷配線基板ユニットの電子回路部品で積算流量リセット処理等が実施できることは公知である。又、流量表示器にスイッチ等を設けておけば、該スイッチの入力により、印刷配線基板ユニットの電子回路部品で積算流量リセット処理等が実施できることも公知である。
【００１１】
【発明が解決しようとする課題】
しかしながら、従来の流量表示器を搭載する浄水器においては、流量センサと圧力（差圧）センサの両方を搭載し、活性炭及び中空糸膜フィルタの両者の寿命を各々表示しているものが見当たらず、ただ規定の通水総流量を超越した時を寿命と判断しているもので、活性炭及び／又は中空糸膜フィルタそのものの寿命を判断しているものでなく、未だ活性炭及び／又は中空糸膜フィルタそのものが使用できる状態であっても、浄水器カートリッジを交換するように表示及び／又は警報させていて、ランニングコスト高であるという問題点があった。
【００１２】
又、浄水器カートリッジにおいても、分解不可能なカートリッジ容器毎廃却（例えば、可燃ごみ、不燃ごみ、資源ごみ等の分別ができない。）していて、ランニングコスト高であり、リサイクルが遅れているという問題点があった。
そして、浄水器が使用される消費者のライフスタイルに合わせ、活性炭の量及び／又は中空糸膜フィルタの中空糸本数等が異なる複数のカートリッジ型式（又は寿命）を有する浄水器カートリッジにおいて、複数のカートリッジ型式を有する浄水器カートリッジを１台の浄水器に取付けて、そのカートリッジ型式（逆取付）を識別（及び／又はその識別に基づき予めＲＯＭ、ＥＥＰＲＯＭ等に登録されている寿命判定値、寿命初期値等を書換〔修正〕）したり、活性炭及び／又は中空糸膜フィルタそのものの寿命を判断したりできる浄水器がないという問題点があった。
【００１３】
流量センサにおいては、設計上、浄水器カートリッジの上方部又は水平部に設置する場合は、流量センサに水と空気とが混在（水に含有されている気体も含む。）すると、流量センサだけでは気水分離機能を持たないために、低流量通水開始時においては回転するはずの回転羽根（羽根車）が回転しない等の障害が発生することがありえるという問題点があった。
【００１４】
圧力センサにおいては、圧力（水圧）を検出するだけの機能だけであり、浄水器として要求される止水弁機能や逆止弁機能等については、別に止水弁や逆止弁等の部材が必要であるという問題点があった。
【００１５】
本発明は、従来の技術の有するこのような問題点を鑑みてなされたものであり、その目的とするところは、低流量通水開始時においても回転羽根（羽根車）が回転する流量センサと、止水弁機能や逆止弁機能等を有する差圧センサと、の複合センサにより、活性炭及び／又は中空糸膜フィルタそのものの寿命を判断し、その寿命等を各々表示及び／又は警報させることができ、又寿命の短い活性炭においては活性炭の交換ができる浄水器カートリッジを採用し、活性炭の量及び／又は中空糸膜フィルタの中空糸本数等により、カートリッジ型式（又は寿命）の異なる複数の浄水器カートリッジが扱える寿命表示器付き浄水器を提供しようとするものである。
【００１６】
【課題を解決するための手段】
上記目的を達成するために、本発明の寿命表示器付き浄水器においては、以下の特徴を有する。
浄水器カートリッジは複数の磁石Ａを埋設し複数のカートリッジ型式（又は寿命）がある浄水器カートリッジを使用し、浄水器本体に複数の磁気検出装置Ａを設け、該磁気検出装置Ａの組合せ信号によりカートリッジ型式及び／又は通水方向逆取付が検出できるものにおいて、浄水器本体から浄水器カートリッジが離脱した場合に「離」と検出判断し、新しい浄水器カートリッジを浄水器本体に取付けた場合に「着」と検出判断し、浄水器カートリッジを通水方向と逆に浄水器本体に取付けた場合に「逆」と検出判断し、「離」の後に「着」が検出され直前に通水方向逆取付がなかった場合、カートリッジ型式別に寿命判定に用いる寿命初期値やデータを書換保持することができ、「離」の後に「逆」が検出され逆流洗浄が実施された場合、保持しているデータを書換（修正）保持することができることを特徴とする。
「離」の後に「着」が検出され直前に通水方向逆取付があった場合は、寿命初期値やデータを書換保持せずに、積算やカウント等の信号処理の続行を行うだけである。同様に「離」の後に「逆」が検出され逆流洗浄が実施されなかった場合は、保持しているデータを書換（修正）保持しないものである。

マイコンの外部に接続される振動子の周波数に基づき分周されたクロックを用いて動作するマイコン内蔵のタイマ／イベント・カウンタ／アップ・ダウン・カウンタ機能等の時間計数部（活性炭が原水に触れたときからの経過時間、待機総時間、通水総時間等）と、
からの信号を演算処理して算出し、活性炭及び／又は中空糸膜フィルタの寿命算出値等を寿命表示器に表示及び／又は警報させたことを特徴とする。

【発明の実施の形態】
発明の実施の形態について図面（但し、一部不図示のものがある。）を参照して説明する。
先ず、本発明の浄水器カートリッジについて説明する。
図６は本発明の第二実施例の寿命表示器付き直結型浄水器（水路管ａ，水路管ｂ搭載型）の斜視図である。ここでは図６に示された本発明の一実施例の活性炭カートリッジ１０を参照しながら説明する。
活性炭カートリッジ１０と中空糸膜フィルタカートリッジ４６とが独立している浄水器において、活性炭カートリッジ１０には、寿命を迎えた活性炭を排出し、新しい活性炭に詰め替えるだけでカートリッジ容器１１（例えば、ＡＢＳ樹脂）が再利用できるように、カートリッジ容器１１に着脱自在な、例えば、螺着式の容器蓋１２（例えば、ＡＢＳ樹脂）を設けた。
【００３７】
図７は本発明の第二実施例の寿命表示器付き直結型浄水器（水路管ａ，水路管ｂ搭載型）の正面パネルを開けた時の要部部分断面図を含む平面図であり、図８は図７から浄水器カートリッジを分離した時の要部部分断面図を含む平面図である。ここでは図８に示された本発明の一実施例の活性炭カートリッジ１０を参照しながら説明する。
不図示ではあるが、必要により、カートリッジ容器１１の流入口１３及び／又は流出口１４に、例えば、６０メッシュの金属メッシュフィルタ等を設けても良い。
又、水抜きを行いたい場合は、カートリッジ容器１１に水抜孔１５を設けても良い。
中空糸膜フィルタカートリッジ４６において、内蔵される中空糸膜フィルタが空気が通過できないものであれば、中空糸膜フィルタカートリッジ４６に空気抜孔４７を設けても良い。又、実開平５−６３６８９号公報等で開示されているように、空気を流出口４８に送る機構を設けても良い。
【００３８】
図２は本発明の第一実施例の寿命表示器付き直結型浄水器（水路管Ａ，水路管Ｂ搭載型）の斜視図であり、図３は本発明の第一実施例の寿命表示器付き直結型浄水器（水路管Ａ，水路管Ｂ搭載型）の底面図であり、図４は本発明の第一実施例の寿命表示器付き直結型浄水器（水路管Ａ，水路管Ｂ搭載型）の正面パネルを開けた時の要部部分断面図を含む平面図である。ここでは図２及び図４に示された本発明の一実施例の浄水器カートリッジ２０を参照しながら説明する。
活性炭２１と中空糸膜フィルタ２２とを有する浄水器カートリッジ２０において、活性炭２１だけが寿命を迎え、中空糸膜フィルタ２２は未だ使用できる場合、活性炭２１を排出し、新しい活性炭２１を詰め替えるだけで浄水器カートリッジ２０が再利用できるように、カートリッジ容器２３（例えば、ＡＢＳ樹脂）に着脱自在な、例えば、螺着式の容器蓋２４（例えば、ＡＢＳ樹脂）を設けた。
容器蓋２４の操作性を考慮すると、螺着式でなくても水圧に耐えれば、ワンタッチ式でもキャップ式等でも良い。
【００３９】
図５は図４から浄水器カートリッジを分離した時の要部部分断面図を含む平面図である。ここでは図５に示された本発明の一実施例の浄水器カートリッジ２０を参照しながら説明する。
不図示ではあるが、必要により、カートリッジ容器２３の流入口２６及び／又は流出口２７に、例えば、６０メッシュの金属メッシュフィルタ等を設けても良い。
又、水抜きを行いたい場合は、カートリッジ容器２３に水抜孔２５を設けても良い。
又、空気が通過できない中空糸膜フィルタ２２であれば、カートリッジ容器２３に空気抜孔２８を設けても良い。又、実開平５−６３６８９号公報等で開示されているように、空気を流出口２７に送る機構を設けても良い。
又、活性炭２１と中空糸膜フィルタ２２をつなぐ通路２９内に、例えば、金属メッシュフィルタ、ゴムメッシュフィルタ、樹脂メッシュフィルタ、不織紙フィルタ、不織布フィルタ、セルローズ繊維フィルタ、ガラス繊維フィルタ、還元性物質、吸着性物質、活性炭、亜硫酸カルシウム、キチンキトサン粉末、シリカゲル、麦飯石等の漢方薬、中空糸膜フィルタ、精密ろ過膜（ＭＦ膜）フィルタ、限外ろ過膜（ＵＦ膜）フィルタ、逆浸透膜（ＲＯ膜）フィルタ、電子交換体、イオン交換体（有機ゼオライト、無機ゼオライト、合成ゼオライト含む。）、イオン交換膜、イオン交換紙、イオン交換繊維、イオン交換樹脂、イオン交換樹脂触媒、オゾン発生装置、磁石（電磁石含む。）、セラミック体（例えば、セラミックボール）、多孔性無機物質、半導体（例えば、樹脂ボール体に二酸化チタンコーティング）等で構成されたもの等があり、さらに、除菌・抗菌・殺菌・微生物抑制剤（例えば、酸化チタン、亜鉛華）等を添加しても良い。
【００４０】
又、活性炭の量（質、形態、製造メーカ）及び／又は中空糸膜フィルタの中空糸本数等（材質、孔径、糸の太さ、断面積、製造メーカ）が異なる複数のカートリッジ型式（又は寿命）を有する浄水器カートリッジ２０において、そのカートリッジ型式及び／又は通水方向逆取付が識別できるように浄水器カートリッジ２０のカートリッジ容器２３に複数の磁石Ａ６３を埋設（一体成形）した。
活性炭カートリッジ１０と中空糸膜フィルタカートリッジ４６のカートリッジ容器にも複数の磁石Ａ６３を埋設しても良い。（図８参照。）
【００４１】
例えば、活性炭３０グラム及び／又は中空糸膜フィルタ３０００本で構成されるカートリッジ型式２０−１の浄水器カートリッジ２０においては、１個の磁石Ａ６３を埋設（磁石有＝１、磁石無＝０とし、配列は００１とする。）し、さらに離れた位置に１個の磁石Ａ６３を埋設（磁石有＝１、磁石無＝０とし、通水方向逆取付検出時の配列が０１０となるようにする。）する。
例えば、活性炭４０グラム及び／又は中空糸膜フィルタ５０００本で構成されるカートリッジ型式２０−２の浄水器カートリッジ２０においては、２個の磁石Ａ６３を間隔を開けて並列（直列、対角線上、横並び、縦並び）に埋設（磁石有＝１、磁石無＝０とし、配列は１０１とする。）し、さらに離れた位置に１個の磁石Ａ６３を埋設（磁石有＝１、磁石無＝０とし、通水方向逆取付検出時の配列が０１０となるようにする。）する。
このように磁石Ａ６３の埋設の仕方を工夫した場合、例えば、浄水器側に搭載される磁気検出装置Ａ（例えば、ホールＩＣ）を合計で３個設けた場合は３通り（磁石有＝１、磁石無＝０とし、配列は００１、１００、１０１）のカートリッジ型式が識別できる。
配列の０００は、浄水器カートリッジ２０が浄水器から離脱した場合に「離」と検出判断できるようにするため、カートリッジ型式検出用には使用しない。
又、配列の０１０は、浄水器カートリッジ２０を通水方向と逆に浄水器本体に取付けた（略して逆取付という。）場合に「逆」と検出判断できるようにするため、カートリッジ型式検出用には使用しない。
【００４２】
ここでは図４の本発明の一実施例の浄水器カートリッジ２０交換用の活性炭パック２１の断面図を参照しながら説明する。
細部においては、寿命を迎えた活性炭２１を排出し、新しい活性炭２１に詰め替えるときに、活性炭交換が容易になるように、新しい活性炭２１（粉末状、粒状、球状）を水（原水）に濡れれば溶解する気密性の良い（保存時に空気に含有される匂いを吸着しないためのもの。）オブラート部材１６（活性炭は塩酸賦活されている場合があり、耐酸性の良いものが選択される。）で包装した。（但し、繊維状、フエルト状の活性炭は扱い易いので、特にオブラート部材１６で包装する必要性が無い場合がある。）
水（原水）に濡れても溶解しない紙やフィルタ等で活性炭２１を、例えば、ティーバック状に包装しても良いが、包装された状態で浄化処理するより、通水により自由自在に浮遊させておいた方が、通水の偏りによる処理ムラが少なくなる効果が期待でき、寿命を迎えた後の活性炭を再活用（例えば、植木、花壇等の土にかけて保水性を向上させる。）したり、リサイクル（再生業者等に依頼して洗浄及び／又は再賦活して頂き再利用する。）したりしやすい。又、紙やフィルタ等はゴミになる可能性が高いのでなるべく使用しない方が良い。
【００４３】
本発明の浄水器について説明する。
図４は本発明の第一実施例の寿命表示器付き直結型浄水器４０（水路管Ａ，水路管Ｂ搭載型）の正面パネル８１を開けた時の要部部分断面図を含む平面図である。図５は図４から浄水器カートリッジ２０を分離した時の要部部分断面図を含む平面図である。
複数の磁石Ａ６３を埋設し複数のカートリッジ型式がある浄水器カートリッジ２０（活性炭カートリッジ１０及び／又は中空糸膜フィルタカートリッジ４６）において、直結型浄水器本体４１（或いは据置型浄水器本体７４）に複数の磁気検出装置Ａ６４（例えば、ホールＩＣ：消費電力を抑えるためには、規定時間毎に通電してデータ・サンプリングすると良い。）を設け、直結型浄水器本体４１（或いは据置型浄水器本体７４）から、例えば、浄水器カートリッジ２０−１（配列検出は００１）が離脱した場合に「離」と検出判断（配列検出は０００）し、例えば、新しい浄水器カートリッジ２０−２を直結型浄水器本体４１（或いは据置型浄水器本体７４）に取付けた場合に「着」と検出判断（配列検出は１０１）し、又該磁気検出装置Ａ６４の組合せ信号によりカートリッジ型式（２０−２）が検出でき、「離」の後に「着」が検出され直前に通水方向逆取付がなかった場合、そのカートリッジ型式（２０−２）の寿命判定に用いる寿命初期値（例えば、活性炭２０００リットル又は６ケ月、中空糸膜フィルタ２００００リットル又は圧力損失０．２ＭＰａ）やデータを、例えば、印刷配線基板ユニット６１内のＥＥＰＲＯＭ、フラッシュメモリ等の外部記憶装置等に書換保持することができる。
「離」の後に「着」が検出され直前に通水方向逆取付があった場合は、寿命初期値やデータを書換保持せずに、積算やカウント等の信号処理の続行を行うだけである。同様に、例えば、悪戯、嵌合状態確認等で、「離」、「着」、「離」、「着」等を短時間のうちに繰り返した時、或いは直結型浄水器本体４１（或いは据置型浄水器本体７４）の清掃（洗浄）の為に新しい浄水器カートリッジ２０との交換に必要な時間等をはるかに越える時間を要して「離」の後に「着」が検出された時等、マイコンに内蔵（ＲＯＭ又はＥＥＰＲＯＭ等）させる処理プログラムやソフトウェア（ノウハウ）にもよるが、積算値、寿命予想等を考慮して、寿命初期値やデータを書換保持せずに、積算やカウント等の信号処理の続行を行うだけである。
【００４４】
又、「離」の後に「逆」が検出判断（配列検出は０１０）され、逆流洗浄（例えば、通水時間４０秒、通水量５リットル）が実施された場合、その洗浄作用により回復された圧力損失等を勘案し、保持しているデータを、例えば、ＥＥＰＲＯＭ等の外部記憶装置に書換（修正）保持することができる。
逆流洗浄が実施されなかった場合は、書換（修正）保持等の処理を何も行わないものである。但し、「逆」が検出判断したフラグ（マイコンが処理しやすいように、ＲＡＭ、ＥＥＰＲＯＭ等に信号があったことを残しておくこと。）は保留しておく。次に「離」の後に「着」が検出された時にフラグリセット（ＲＡＭ、ＥＥＰＲＯＭ等のフラグを取り消すこと。）し、積算やカウント等の信号処理の続行が行えるようにする。
【００４５】
そして、浄水器カートリッジ２０のカートリッジ型式（２０−２）及び／又は通水方向逆取付や、寿命初期値（例えば、活性炭２０００リットル又は６ケ月、中空糸膜フィルタ２００００リットル又は圧力損失０．２ＭＰａ）及び／又はデータ書換（修正）値等を寿命表示器４２に表示及び／又は警報させることができる。
参考ではあるが、寿命初期値等は、浄水器カートリッジ製造メーカ等の保証値（実績値）等だけでなく、日本工業規格 JIS S 3201(1999) 家庭用浄水器試験方法、昭和３７年法律第１０４号家庭用品品質表示法、等を考慮して決定すると良い。
【００４６】
又、活性炭２１及び／又は中空糸膜フィルタ２２の寿命は、流量センサ３０と、差圧センサ５９と、時間計数部６５（通常は印刷配線基板ユニット６１に搭載されるマイコン６０に内蔵されている。）と、からの信号を演算処理して算出し、活性炭２１の寿命算出値及び／又は中空糸膜フィルタ２２の寿命算出値を寿命表示器４２に表示及び／又は警報させた。

ダイヤフラム５０と、ダイヤフラム板５１と、コア５３と、圧縮渦巻発条５５と、からなる圧力変位体４９と、該圧力変位体４９の外周壁近傍に配設され接離動不可能な磁気検出装置Ｃ５６（例えば、磁気検出コイル）と、からなる磁気検出コイル式差圧センサ５７（例えば、磁気検出コイルをＬとし、コンデンサをＣとした場合に、ＬＣ共振（発振）回路を構成し、規定時間毎に通電してデータ・サンプリングすれば、消費電力が抑えられる。）、又は、ダイヤフラム５０と、ダイヤフラム板５１と、磁石Ｃ５４と、圧縮渦巻発条５５と、からなる圧力変位体４９と、該圧力変位体４９の外周壁近傍に接離動可能に別設される磁気検出装置Ｃ５６（例えば、ホールＩＣ：消費電力を抑えるためには、規定時間毎に通電してデータ・サンプリングすると良い。）と、からなる磁気感動素子式差圧センサ５８と、
マイコン６０の外部に接続される振動子（例えば、水晶振動子、セラミック振動子）の周波数（例えば、５ＭＨｚ、３２．７６８ｋＨｚ）に基づき分周されたクロックを用いて動作するマイコン内蔵のタイマ／イベント・カウンタ／アップ・ダウン・カウンタ機能等の時間計数部６５（例えば、活性炭が原水に触れたときからの経過時間、待機総時間、通水総時間等を計測するもの。）と、
からの信号を演算処理して算出し、活性炭２１及び／又は中空糸膜フィルタ２２の寿命算出値等を寿命表示器４２に表示及び／又は警報させることができる。
【００４８】
本発明の一実施例では、磁気検出装置Ｂ３７及びリード線６６（配線材）の一部をポッティング材（例えば、ウレタン樹脂、ポリエステル樹脂、エポキシ樹脂、シリコーン樹脂等の電気絶縁材、接着シール材等で、他の材質の防水対策材、防湿対策材、結露対策材用等のものも含む。）で封止したものである。
該磁気検出装置Ｃ５６を、例えば、磁気検出コイルとした場合は、防水、防湿、結露対策のために、電気絶縁充填材（例えば、ポリエステル樹脂、エポキシ樹脂、シリコーン樹脂、ウレタン樹脂）の充填や、電気絶縁材（例えば、ポリエステル樹脂、エポキシ樹脂、シリコーン樹脂、ウレタン樹脂等の接着シール材等で、他の材質の防水対策材、防湿対策材、結露対策材用等のものも含む。）の塗布を行うと良い。

図１は本発明の第一実施例の寿命表示器付き直結型浄水器（水路管Ａ，水路管Ｂ搭載型）をシンクに取付けた時の使用状態を示す参考斜視図である。
浄水器の形態としては、流量検出体３１と圧力変位体４９とを内蔵する流水検出管９０と、流量検出体３１の磁気を検出する磁気検出装置Ｂ３７と、圧力変位体４９の磁気を検出する磁気検出装置Ｃ５６と、該磁気検出装置Ｂ３７及び該磁気検出装置Ｃ５６からの信号を演算処理する電子回路部品が実装された印刷配線基板ユニット６１と、表示装置４３及び／又は警報装置４４からなる寿命表示器４２と、槓杆７１を有する切替弁本体７０（浄水器ケース内の収納スペースとコストと等さえ許せば、表示装置４３等に操作スイッチ等を設けて、電動等で切替弁本体７０を回動させても良い。）と、直結型浄水器ケース８０（浄水器カートリッジ２０用は８０−１、活性炭カートリッジ１０及び／又は中空糸膜フィルタカートリッジ４６用は８０−２）と、からなる直結型浄水器本体４１（浄水器カートリッジ２０用は４１−１、活性炭カートリッジ１０及び／又は中空糸膜フィルタカートリッジ４６用は４１−２）と、浄水器カートリッジ２０（或いは活性炭カートリッジ１０及び／又は中空糸膜フィルタカートリッジ４６）と、からなる直結型浄水器４０〔いわゆる槓杆切替栓一体型浄水器〕（浄水器カートリッジ２０用は４０−１、活性炭カートリッジ１０及び／又は中空糸膜フィルタカートリッジ４６用は４０−２）とした。
流水検出管９０の原水流入口（１０１）には、図３に示した安全弁７７等を設けると良い。
切替弁本体７０と流量検出体３１と圧力変位体４９とを、原水の高水圧（例えば、動水圧で０．５ＭＰａ〔メガパスカル〕以上）による破裂（水漏れ、変形、破損その他の異常）等から保護するためのものではあるが、必要により安全弁７７の作動圧力設定を高く（例えば、０．８ＭＰａ以上）しておいた方が良いかもしれない。
安全弁７７の作動圧力設定は、コイルスプリング（例えば、ステンレス鋼線）のバネ定数で固定（例えば、０．８ＭＰａ）されているので、あまり作動圧力設定を低くしておくと、作動バラツキ（コイルスプリングのバネ定数等のバラツキ）により、止水不良と間違われるような放水状態が有り得るので、注意が必要である。

Conventional mainstream water purifier cartridges include activated carbon cartridges, hollow fiber membrane filter cartridges, activated carbon + hollow fiber membrane filter cartridges, and the like.
In detail, activated carbon has powder, granular, spherical, fiber, felt, etc., and hollow fibers used in hollow fiber membrane filters have materials such as polyethylene hollow fibers, polysulfone hollow fibers, etc. .
Normally, depending on the amount (total surface area) and quality of activated carbon (silver addition, activation method, removal of organic substances for residual chlorine decomposition, new recycled products), service life (for example, specified [2ppm] residual chlorine concentration-containing tap water is allowed to pass through. , The case where purified water containing residual chlorine concentration of specified [0.4 ppm] is discharged). The life here means the total amount of residual chlorine (tap water) that can be treated by activated carbon. Moreover, there is a use limit (expiration life) due to the inactivation (deterioration) characteristics of the activated carbon.
Also, depending on the number of hollow fiber membrane filters (pore size, total surface area, cross-sectional area), the life (for example, tap water containing turbidity of specified [turbidity of 10] is allowed to pass through, and turbidity of specified [turbidity of 2] is contained. When purified water is discharged)) is different. The term “lifetime” as used herein refers to the total amount of turbidity (tap water) that can be treated, not the usage time of the hollow fiber membrane filter.

[Problems to be solved by the invention]
However, in the water purifier equipped with the conventional flow rate indicator, there is no one that has both the flow rate sensor and the pressure (differential pressure) sensor, and displays the lifetimes of both the activated carbon and the hollow fiber membrane filter. However, it is determined that the lifetime exceeds the specified total water flow rate, not the lifetime of the activated carbon and / or the hollow fiber membrane filter itself, but is still activated carbon and / or the hollow fiber membrane. Even when the filter itself can be used, the water purifier cartridge is displayed and / or alarmed to be replaced, and there is a problem that the running cost is high.
[0012]
In addition, the water purifier cartridge is also disposed of each non-decomposable cartridge container (for example, combustible waste, non-combustible waste, recyclable waste cannot be separated), running costs are high, and recycling is delayed. There was a problem.
And in the water purifier cartridge which has several cartridge types (or lifetime) from which the quantity of activated carbon and / or the number of hollow fibers of a hollow fiber membrane filter differ according to the lifestyle of the consumer in which a water purifier is used, A water purifier cartridge having a cartridge type is attached to one water purifier, and the cartridge type (reverse mounting) is identified (and / or a life judgment value registered in advance in a ROM, EEPROM, etc. based on the identification, life initial value There has been a problem that there is no water purifier capable of rewriting (correcting) the value or the like, or judging the life of the activated carbon and / or the hollow fiber membrane filter itself.
[0013]
In the design of the flow sensor, when it is installed in the upper part or the horizontal part of the water purifier cartridge, if water and air are mixed in the flow sensor (including gas contained in water), the flow sensor alone Since there is no air-water separation function, there is a problem that a failure such as a rotation blade (impeller) that should rotate at the start of low flow rate water flow may occur.
[0014]
The pressure sensor only has a function of detecting pressure (water pressure). For the water stop valve function and check valve function required as a water purifier, there are separate members such as a water stop valve and a check valve. There was a problem that it was necessary.
[0015]
  The present invention has been made in view of such problems of the prior art, and the object of the present invention is to provide a flow sensor in which a rotating blade (impeller) rotates even at the start of low-flow water flow. The life of the activated carbon and / or the hollow fiber membrane filter itself is judged by a combined sensor with a differential pressure sensor having a water stop valve function, a check valve function, etc., and the life etc. is displayed and / or alarmed. In the case of activated carbon with a short life, a water purifier cartridge that can replace the activated carbon is adopted, and a plurality of purified water with different cartridge types (or lifetimes) depending on the amount of activated carbon and / or the number of hollow fibers of the hollow fiber membrane filter, etc. Water purifier with a life indicator that can handle water cartridgesTheIt is something to be offered.

Multiple cartridge types (or lifetimes) with different amounts of activated carbon (quality, form, manufacturer) and / or number of hollow fiber membrane filters (material, pore diameter, thread thickness, cross-sectional area, manufacturer) A plurality of magnets A63 are embedded (integrated) in the cartridge container 23 of the water purifier cartridge 20 so that the cartridge type and / or reverse installation in the water flow direction can be identified.
A plurality of magnets A63 may also be embedded in the cartridge containers of the activated carbon cartridge 10 and the hollow fiber membrane filter cartridge 46. (See Figure 8.)
[0041]
For example, in the water purifier cartridge 20 of the cartridge type 20-1 composed of 30 grams of activated carbon and / or 3000 hollow fiber membrane filters, one magnet A63 is embedded (with magnet = 1, without magnet = 0, The arrangement is 001.) Further, one magnet A63 is embedded at a further distant position (magnet present = 1, no magnet = 0) so that the arrangement when detecting reverse installation in the water flow direction is 010. )
For example, in the water purifier cartridge 20 of the cartridge type 20-2 composed of 40 grams of activated carbon and / or 5000 hollow fiber membrane filters, two magnets A63 are arranged in parallel at intervals (in series, diagonally, side by side, Embedded vertically (with magnet = 1, no magnet = 0, array 101), and one magnet A63 is embedded further away (with magnet = 1, without magnet = 0), The arrangement at the time of detecting reverse installation of the water flow direction is set to 010).
Thus, when devising the method of embedding magnet A63, for example, when three magnetic detection devices A (for example, Hall IC) mounted on the water purifier side are provided in total, there are three ways (magnet present = 1, The magnet type = 0, and the arrangement of cartridge types 001, 100, 101) can be identified.
The 000 of the array is not used for cartridge type detection so that it can be detected and judged as “separated” when the water purifier cartridge 20 is detached from the water purifier.
In addition, 010 in the arrangement is for detecting the cartridge type so that it can be detected and judged as “reverse” when the water purifier cartridge 20 is attached to the main body of the water purifier opposite to the direction of water flow (abbreviated as “reverse mounting” for short). Not used for.
[0042]
Here, it demonstrates, referring sectional drawing of the activated carbon pack 21 for water purifier cartridge 20 replacement | exchange of one Example of this invention of FIG.
In detail, when the activated carbon 21 that has reached the end of its life is discharged and refilled with new activated carbon 21, the activated carbon 21 (powder, granular, spherical) is wetted with water (raw water) so that the activated carbon can be easily replaced. It has good airtightness to dissolve (to prevent adsorption of odors contained in air during storage). Oblate member 16 (activated carbon may be activated by hydrochloric acid, and one with good acid resistance is selected.) Wrapped with. (However, since the fibrous and felt-like activated carbon is easy to handle, there is a case where it is not particularly necessary to wrap with the oblate member 16.)
The activated carbon 21 may be packaged in, for example, a tea bag with paper or a filter that does not dissolve even when wet with water (raw water), but it can be floated freely by passing water rather than being purified in the packaged state. If you leave it, you can expect the effect of reducing the processing unevenness due to the uneven flow of water, and reuse the activated carbon after reaching the end of its life (for example, to improve the water retention performance over soil such as plants and flower beds). It is easy to recycle (recycled by requesting a recycler etc. and / or reactivated). Also, it is better not to use paper, filters, etc. as much as possible because they are likely to become dust.

For example, a new water purifier cartridge 20-2 is directly connected to the water purifier. When it is attached to the main body 41 (or stationary water purifier main body 74), it is detected as “arrived” (array detection is 101), and the magnetic detection device When the cartridge type (20-2) can be detected by the combination signal of A64, and “arrival” is detected after “release” and there is no reverse installation in the water flow direction immediately before, the life determination of the cartridge type (20-2) is made. Life initial values (for example, activated carbon 2000 liters or 6 months, hollow fiber membrane filter 20000 liters or pressure loss 0.2 MPa) and data, for example, an external storage device such as an EEPROM or a flash memory in the printed wiring board unit 61 Etc. can be rewritten and retained.
If “attachment” is detected after “separation” and there is reverse installation in the water flow direction immediately before, only signal processing such as integration and counting is continued without rewriting and maintaining the initial life value and data. . Similarly, for example, when "separation", "arrival", "separation", "arrival", etc. are repeated in a short time in mischief, fitting state confirmation, etc., or directly connected water purifier main body 41 (or stationary For example, when “wearing” is detected after “separation” taking much longer than the time required for replacement with a new water purifier cartridge 20 for cleaning (cleaning) of the water purifier main body 74) Depending on the processing program and software (know-how) built into the microcomputer (ROM or EEPROM etc.), taking into account the accumulated value, life expectation, etc. The signal processing is simply continued.
[0044]
In addition, after “separation”, “reverse” is detected and judged (array detection is 010), and when back-flow cleaning (for example, water flow time 40 seconds, water flow rate 5 liters) is performed, it is recovered by the cleaning action. Considering the pressure loss and the like, the retained data can be rewritten (corrected) and retained in an external storage device such as an EEPROM.
When the backwashing is not performed, no processing such as rewriting (correction) holding is performed. However, the flag detected as “reverse” (remaining that there was a signal in the RAM, EEPROM, etc. so that the microcomputer can easily process it) is reserved. Next, when “arrival” is detected after “release”, the flag is reset (cancellation of flags such as RAM, EEPROM, etc.) so that signal processing such as integration and counting can be continued.

And the cartridge type (20-2) and / or water flow direction reverse mounting of the water purifier cartridge 20 and the life initial value (for example, activated carbon 2000 liters or 6 months, hollow fiber membrane filter 20000 liters or pressure loss 0.2 MPa) And / or a data rewrite (correction) value or the like can be displayed on the life indicator 42 and / or alarmed.
