Description

【０００１】
【発明の属する技術分野】
本発明は人体の局部に洗浄水をノズルの噴出口から噴出して人体の局部を洗浄する人体局部洗浄装置に関し、殊にマッサージ効果を改善した人体局部洗浄装置に関する。
【０００２】
【従来の技術】
人体局部洗浄装置は、人体の局部に向けて洗浄水を噴出して局部を洗浄するノズルを有するものである。更に、近年、洗浄時の単調感を解消したり、痔疾者等に対する改善を図った人体局部洗浄装置として、人体の局部に向けて噴出される設定水量を中心とする水量変化を与えるもの（特公平３−１０７７３号公報、特公平３−１６４６１号公報）、局部に向けて噴出される設定水量を中心とする水量の変化を与えつつも、設定水量とは無関係に少なくとも１回は多めの洗浄水量を噴出し、洗浄効果を高めるもの（特公平３−１０７７４号公報）が知られている。これらの公報に係る装置では、直線的に噴出される直線流を人体の局部に噴出させるものであり、設定値を中心とする水量の変化により、人体の局部に対するマッサージ効果が得られる。
【０００３】
【発明が解決しようとする課題】
しかしながら上記した公報に係る人体局部洗浄装置は、水量の変化により、人体局部に対するある程度のマッサージ効果が得られるものの、人体の局部に向けて洗浄水が直線的に噴出されるため、人体に対するマッサージ効果は必ずしも充分ではなく、さらなる開発が要望されている。
【０００４】
本発明は上記した実情に鑑みてなされたものであり、その課題は、洗浄水の拡散流と洗浄水の直線流とを混合させ、その混合比を変更することにより、人体の局部に対するマッサージ効果を高めた人体局部洗浄装置を提供することにある。
【０００５】
【課題を解決するための手段】
（１）様相１（請求項１）の本発明に係る人体局部洗浄装置は、便器に搭載され人体の局部に洗浄水を噴出口から噴出して人体の局部を洗浄する洗浄機構を有する人体局部洗浄装置において、
洗浄機構は、洗浄水を拡散させる拡散流となる洗浄水が流れる拡散流給水路と、拡散流給水路よりも直線的な直線流となる洗浄水が流れる直線流給水路とをもつノズルと、
ノズルの拡散流給水路及び直線流給水路に接続され作動に伴いノズルの拡散流給水路の水量と直線流給水路の水量との混合比を変更可能なバルブと、
バルブに接続され駆動に伴いバルブを作動させて拡散流給水路の水量と直線流給水路の水量との混合比を自動で変更することにより、ノズルの噴出口から人体の局部に向けて噴出される洗浄水の洗浄面積を経時的に変化させる駆動源とを具備していることを特徴とするものである。
【０００６】
様相１の本発明装置においては、バルブは、作動に伴い、ノズルの拡散流給水路の水量と直線流給水路の水量との混合比を変える。このバルブは駆動源により自動的に作動される。このように駆動源が駆動してバルブが作動すれば、バルブの作動により上記混合比が自動的に変更される。この結果、ノズルの噴出口から人体局部に向けて噴出される洗浄水において、経時的に、拡散流の水量が増加したり直線流の水量が増加したりする。拡散流の水量が増加したときには、洗浄面積が増加し、マイルドな洗浄感が得られる。直線流の水量が増加したときには、洗浄面積が低減され、局所的な強い洗浄感が得られる。拡散流と直線流との水量の割合が中間となったときには、中間の洗浄感が得られる。
【０００７】
上記したように本発明装置においては駆動源の駆動によりバルブが自動的に作動し、拡散流給水路の水量と直線流給水路の水量との混合比が自動的に変更されるため、マイルドな洗浄感、局所的な強い洗浄感、中間の洗浄感が経時的に繰り返されることになり、人体の局部に対するマッサージ効果が得られる。
【０００８】
（２）様相２（請求項２）の本発明に係る人体局部洗浄装置は、便器に搭載され人体の局部に洗浄水を噴出口から噴出して人体の局部を洗浄する洗浄機構を有する人体局部洗浄装置において、
洗浄機構は、洗浄水を拡散させる拡散流となる洗浄水が流れる拡散流給水路と、拡散流給水路よりも直線的な直線流となる洗浄水が流れる直線流給水路とをもち、噴出口の上流において拡散流給水路の拡散流と直線流給水路の直線流とを混合させるノズルと、
ノズルの拡散流給水路及び直線流給水路に接続され作動に伴いノズルの拡散流給水路の水量と直線流給水路の水量との混合比を変更可能なバルブと、バルブに接続され駆動に伴いバルブを作動させて拡散流給水路の水量と直線流給水路の水量との混合比を自動で変更する駆動源とを具備していることを特徴とするものである。
【０００９】
様相２の本発明装置においては、バルブは、作動に伴い、ノズルの拡散流給水路の水量と直線流給水路の水量との混合比を変える。このバルブは駆動源により自動的に作動される。このように駆動源が駆動してバルブが作動すれば、バルブの作動により上記混合比が自動的に変更される。この結果、ノズルの噴出口から人体局部に向けて噴出される洗浄水において、経時的に、拡散流の水量が増加したり直線流の水量が増加したりする。拡散流の水量が増加したときには、洗浄面積が増加し、マイルドな洗浄感が得られる。直線流の水量が増加したときには、洗浄面積が低減され、局所的な強い洗浄感が得られる。拡散流と直線流との水量の割合が中間となったときには、中間の洗浄感が得られる。
【００１０】
上記したように本発明装置においては駆動源の駆動によりバルブが自動的に作動し、拡散流給水路の水量と直線流給水路の水量との混合比が自動的に変更されるため、マイルドな洗浄感、局所的な強い洗浄感、中間の洗浄感が経時的に繰り返されることになり、人体の局部に対するマッサージ効果が得られる。
【００１１】
【発明の実施の形態】
本発明は次の形態の少なくとも一を採用できる。
・バルブは、ノズルの拡散流給水路の水量を増加させると共に直線流給水路の水量を減少させる形態と、ノズルの拡散流給水路の水量を減少させると共に直線流給水路の水量を増加させる形態と、両者の中間の形態とに切替可能とすることができる。この場合、ノズルの噴出口から噴出される洗浄水の単位時間当たりの合計水量をほぼ一定に維持するのに有利となる。この結果、拡散流の割合と直線流の割合とを変更させつつも、単位時間当たりの合計水量が確保され、人体局部に対する洗浄能力の低下を抑え得る。なお、場合によっては、ノズルから噴出される洗浄水の合計水量を変化させる方式とし、時間の進行につれて、ノズルから噴出される洗浄水の合計水量を増加させたり減少させたりしても良い。
・バルブは、拡散流給水路に連通する第１開口と、直線流給水路に連通する第２開口と、第１開口の開口面積及び第２開口の開口面積を可変とする可変部とを有する形態を採用できる。第１開口は、例えば、一方向に向かうにつれて開口幅が次第に増加すると共に他方向に向かうにつれて開口幅が次第に減少するように形成できる。第２開口は、例えば、一方向に向かうにつれて開口幅が次第に減少すると共に他方向に向かうにつれて開口幅が次第に増加するように形成できる。一方向または他方向に向けて可変部が移動すれば、第１開口の開口面積及び第２開口の開口面積をそれぞれ可変とすることができる。この場合、駆動源であるモータが駆動すれば、バルブが作動するため、拡散流給水路に供給される洗浄水の水量、及び、直線流給水路に供給される洗浄水の水量を自動的に可変にすることができる。ひいては、拡散流給水路に供給される洗浄水の水量と、直線流給水路に供給される洗浄水の水量との混合比を自動的に変更することができる。なお混合比の変更は、無段階に変更する形態でも良いし、段階的に変更する形態でも良い。
・バルブを作動させるための駆動源としてのモータを駆動するためのマッサージスイッチを設けることができる。マッサージスイッチは洗浄開始・終了を指令する洗浄スイッチに組み込んでも良いし、洗浄スイッチと別体で設けても良い。
・ノズルは、人体の局部に対面可能で且つ拡散流給水路及び直線流給水路の双方に共通する噴出口を有する形態を採用できる。この場合、拡散流給水路の洗浄水、直線流給水路の洗浄水は、共通する噴出口から噴出される。この場合、拡散流と直線流とがそれぞれ専用の噴出口から個別に噴出される場合に比較して、拡散流と直線流とを良好に混合させるのに有利となる。
【００１２】
【実施例】
以下、本発明の実施例を図面を参照して説明する。
【００１３】
本実施例に係る人体局部洗浄装置は人体の局部を洗浄する機能を有するものであり、便器１００の後部に搭載される。この人体局部洗浄装置は、図１に示すように、便器１００の後部に搭載されるケース１０と、ケース１０に揺動可能に接続された便座１２と、便蓋１３と、人体局部を洗浄する洗浄水を噴出する洗浄機構１４とを有する。ケース１０は、使用者の操作に基づいて洗浄の開始・終了を指令する洗浄スイッチ１１ａ、使用者の操作に基づいてマッサージ処理を指令するマッサージスイッチ１１ｂ等を有する操作パネル１１ｄをもつ。
【００１４】
図２に示すように、洗浄機構１４は、シリンダ状の基部２と、洗浄水を噴出するノズル３と、洗浄形態を切り替えるバルブ４と、バルブ４を作動させるための駆動源であるバルブモータ６（モータ）とをもつ。バルブモータ６はバルブモータ駆動回路７０を介して、マイコン内蔵の制御装置７により制御される。制御装置７には、使用者の操作に基づいて、前記した洗浄スイッチ１１ａからの信号、マッサージ処理を指令するマッサージスイッチ１１ｂからの信号がそれぞれ入力される。
【００１５】
ノズル３は人体の肛門等の局部に洗浄水を噴出して局部を洗浄するものである。このノズル３は、基部２に前進後退可能につまり矢印Ｘ１，Ｘ２方向に移動可能に設けられており、図略のノズルモータの駆動により、人体局部を洗浄するときには矢印Ｘ１方向に前進し、洗浄が終了すると、矢印Ｘ２方向に後退する。
【００１６】
図３はノズル３の先端付近の縦断面を示す。図４は図３のIV-IV線に沿った断面を示す。図５は図３のV-V線に沿った横断面を示す。図３に示すように、ノズル３の内部には、拡散流給水路３１及び直線流給水路３２がほぼ平行に並走されている。図５に示すようにノズル３の横断面は小判型とされている。図５に示すように、拡散流給水路３１及び直線流給水路３２は、ノズル３内に横断面が偏平形状となるように形成されている。図２に示すように、バルブ４と拡散流給水路３１とは第１水路４１により接続されていると共に、バルブ４と直線流給水路３２とは第２水路４２により接続されている。これによりバルブ４を介して拡散流給水路３１及び直線流給水路３２に洗浄水がそれぞれ個別に供給される。
【００１７】
図３に示すように、ノズル３の先端側のうち、人体の局部に対面する側の表面３ｉには、中心軸芯Ｐを有する１個の噴出口３４が形成されている。噴出口３４は拡散流給水路３１及び直線流給水路３２の双方に連通しており、拡散流給水路３１及び直線流給水路３２の双方に共通するものである。従って、噴出口３４は拡散流給水路３１からの洗浄水、直線流給水路３２からの洗浄水を合流させて吐出する。
【００１８】
図３に示すように、ノズル３の内部において、拡散流給水路３１は人体の局部に対面する表面３ｉ側に設けられており、噴出口３４に連通する。拡散流給水路３１の先端側には、拡散流給水路３１内の洗浄水に旋回効果を与える旋回促進部５が形成されている。ノズル３の内部において、直線流給水路３２は人体の局部に背向する裏面３ｓ側に設けられており、連通口３７を介して拡散流給水路３１、噴出口３４に連通している。なお、連通口３７、噴出口３４、後述の旋回室３は、噴出口３４の中心軸芯Ｐに対して同軸的配置とされている。
【００１９】
図４に示すように、前記した旋回促進部５は、外壁面５１が断面円形状をなす壁体５２と、壁体５２の内部に形成された旋回室５３と、旋回室５３と拡散流給水路３１とを連通すると共に拡散流給水路３１を流れた洗浄水を旋回室５３に供給するスリット状の複数個の貫通孔５４とを有する。貫通孔５４は中心軸芯Ｐに対して偏った位置に形成されている。旋回室５３は洗浄水の旋回を促すための円弧に沿った円弧壁面５３ｍを有する。拡散流給水路３１に所定の水圧で供給された洗浄水は、貫通孔５４の入口５４ａから貫通孔５４内に進入し、貫通孔５４の出口５４ｃから旋回室５３に吐出され、旋回室５３を経て、噴出口３４からノズル３の外方に噴出される。図４において水の流れを矢印として示す。貫通孔５４及び旋回室５３を流れる際に、洗浄水に旋回作用が付与される。このため旋回室５３を経て噴出口３４から噴出された洗浄水は、図６に概念イメージを模式的に示すように、噴出口３４側では径が小さいものの、噴出口３４から離れるにつれて、つまり上方に向かうにつれて、遠心力により径が大きくなり、ほぼ円錐形状をなす拡散水流が得られる。このような拡散水流は洗浄面積が大きくなるため、直線流だけの場合に比較して、マイルドな洗浄感が得られる。
【００２０】
図７はバルブ４を示す。バルブ４は、拡散流給水路３１に連通する第１開口４４と、直線流給水路３２に連通する第２開口４６と、第１開口４４の開口及び第２開口４６の開口を塞ぐ可動式の可変部４８とを有する。可変部４８は径方向に沿ったＵ字形状の開口溝４８ｘを有する。前記したバルブモータ６が駆動すると、バルブ４の可変部４８はこれの軸芯Ｓの回りで回動する。
【００２１】
図７に示すように、第１開口４４は円弧形状をなしており、周方向の一方向つまり矢印Ｂ１方向に向かうにつれて開口幅が大きくなり、周方向の他方向つまり矢印Ｂ２方向に向かうにつれて開口幅が小さくなるように形成されている。第２開口４６は円弧形状をなしており、周方向の一方向つまり矢印Ｂ１方向に向かうにつれて開口幅が小さくなり、周方向の他方向つまり矢印Ｂ２方向に向かうにつれて開口幅が大きくなるように形成されている。従って第１開口４４及び第２開口４６は、開口幅の増減方向が逆である。
【００２２】
一方向（矢印Ｂ１方向）または他方向（矢印Ｂ２方向）に向けて可変部４８が回動すれば、第１開口４４と開口溝４８ｘとが対面する面積が変化する。同様に、第２開口４６と開口溝４８ｘとが対面する面積が変化する。この結果、拡散流給水路３１に連通する第１開口４４の開口面積、及び、直線流給水路３２に連通する第２開口４６の開口面積を連続的に変更にすることができる。
【００２３】
本実施例においては、便座１２に着座している使用者がマッサージスイッチ１ｂを操作すると、その信号は制御装置７に入力され、バルブモータ駆動回路７０を経てバルブモータ６が駆動する。これにより、一方向（矢印Ｂ１方向）または他方向（矢印Ｂ２方向）に向けての可変部４８がこれの軸芯Ｓの回りで連続的に回動する。
【００２４】
このように可変部４８が回動すると、可変部４８の開口溝４８ｘが回動するため、拡散流給水路３１に供給される洗浄水の水量、及び、直線流給水路３２に供給される洗浄水の水量を連続的に変化させることができる。ひいては、拡散流給水路３１に供給される洗浄水の水量と、直線流給水路３２に供給される洗浄水の水量との混合比を無段階に変更させることができる。この結果、噴出口３４から噴出される洗浄水において、直線流を多めとしたり、拡散流を多めとしたりする調整を周期的に且つ連続的に行い得る。このため、旋回を伴って噴出口３４からほぼ円錐形状に噴出される洗浄水の径を連続的に変化させることができる。
【００２５】
更に図７を参照して説明を加える。即ち、図７（Ａ）の（ｉ）に示すように、可変部４８の開口溝４８ｘが、第１開口４４の開口幅の大きい部分４４ｗと第２開口４６の開口幅の小さい部分４６ｎとに連通するときには、拡散流の水量の割合が増加すると共に直線流の水量の割合が低下する。従って図７（Ａ）の（ｉｉ）に示すように、ノズル３の噴出口３４から人体局部に向けて噴出される洗浄水は、遠くに噴出されるにつれて拡径するように円錐形状気味となる。よって、洗浄面積が増加するため、マイルドな『弱』の洗浄感が得られる。
【００２６】
図７（Ｃ）の（ｉ）に示すように、可変部４８の開口溝４８ｘが、第１開口４４の開口幅の小さい部分４４ｎと第２開口４６の開口幅の大きい部分４６ｗとに連通するときには、拡散流の水量の割合が減少すると共に直線流の水量の割合が増加する。従って図７（Ｃ）の（ｉｉ）に示すように、ノズル３の噴出口３４から人体局部に向けて噴出される洗浄水は、直線流気味に噴出される。よって、洗浄面積が減少するため、『強』の洗浄感が得られる。
【００２７】
図７（Ｂ）の（ｉ）に示すように、可変部４８の開口溝４８ｘが第１開口４４の開口幅の中間の部分４４ｍと、第２開口４６の開口幅の中間の部分４６ｍとに連通するときには、拡散流の水量と直線流の水量とが同じ程度となる。従って図７（Ｂ）の（ｉｉ）に示すように、ノズル３の噴出口３４から人体局部に向けて噴出される洗浄水は中程度の噴出水となり、『中』の洗浄感が得られる。
【００２８】
本実施例においては、使用者がマッサージスイッチ１１ｂをオン操作すると、バルブモータ６が駆動し、バルブ４の可変部４８が矢印Ｂ１方向または矢印Ｂ２方向の連続的に往復作動するため、洗浄水の『弱』『中』『強』が繰り返され、これにより人体の局部に対するマッサージ処理を良好に行うことができ、殊に痔疾者等の使用に適する。
【００２９】
ところで上記した従来技術では、マッサージ処理を行うため、前述のように、人体の局部に向けて噴出される設定水量を中心とする水量変化を与える方式が採用されている。この方式の場合、設定水量よりも水量が減少するときには、洗浄能力が低下する問題がある。この点実施例においては、バルブ４は、拡散流給水路３１の水量を増加させるときには、直線流給水路３２の水量を減少させる。また、バルブ４は、拡散流給水路３１の水量を減少させるときには、直線流給水路３２の水量を増加させる。このため本実施例においてはノズル３に供給される単位時間当たりの水量はほぼ一定に維持される。故に本実施例においては、拡散流の水量と直線流の水量との混合比を変更させることによりマッサージ効果を得つつも、ノズル３の噴出口３４から噴出される洗浄水の単位時間当たりの水量自体が基本的には一定に維持されるため、人体の局部に対する洗浄能力を低下させることなく良好に確保することができる。
【００３０】
加えて本実施例においては、図５に示すように、拡散流給水路３１及び直線流給水路３２の横断面形状は偏平形状とされているため、拡散流給水路３１及び直線流給水路３２をノズル３の内部にコンパクトに配置することができ、ノズル３の大型化を防止できる。
【００３１】
また本実施例においては、拡散流給水路３１の洗浄水、直線流給水路３２の洗浄水は、双方に共通する噴出口３４から噴出される。この場合、拡散流と直線流とが独立の噴出口から個別に噴出される場合に比較して、拡散流と直線流とを良好に混合させるのに有利となり、水量を減少させることなくマイルドな洗浄感を得ることができ、この意味においても良好なるマッサージ効果を確保できる。
【００３２】
図８は制御装置７のマイコンが実行するマッサージ処理のサブルーチンの代表的なフローチャートを示す。図８に示すように、ステップＳ１０２において制御装置のマイコンはマッサージスイッチ１ｂを読み込み、マッサージスイッチ１ｂがオンされているか否か判定する。マッサージスイッチ１ｂがオンであれば、ステップＳ１０４に進み、バルブモータ６を駆動させるバルブ４を開閉作動させる。次にステップＳ１０６に進み、マッサージスイッチ１ｂを読み込み、マッサージスイッチ１ｂがオフか否か判定する。マッサージスイッチ１ｂがオフであれば、バルブモータ６を停止させ、ステップＳ１１０でその他の処理を行い、メインルーチンに戻る。ステップＳ１０６において判定した結果、マッサージスイッチ１ｂがオンであれば、ステップＳ１０４に戻り、バルブモータ６の駆動を継続する。これによりマッサージスイッチ１ｂがオフとなるまで、バルブモータ６は駆動を継続し、バルブ４は作動を継続するため、洗浄水の『弱』『中』『強』が繰り返され、人体の局部に対するマッサージ効果を良好に行うことができる。上記したフローチャートは一例であり、これに限定されるものではない。
【００３３】
その他、本発明は上記した且つ図面に示した実施例のみに限定されるものではなく、要旨を逸脱しない範囲内で適宜変更して実施できるものである。例えば旋回促進部５における貫通孔５４は複数個に限らず１個としても良い。また旋回促進部５は上記したものに限定されず、洗浄水を旋回させるための羽根車などを有するものでも良い。またバルブ４は上記した機構に限定されず、ノズル３における拡散流給水路３１の水量と直線流給水路３２と水量との混合比を変更できる機能を有するものであれば良い。また上記した実施例においては、バルブモータ６の駆動により可変部４８はこれの周方向に沿って所定距離往復回動する方式であるが、これに限らず、バルブの可動部としては、周方向に連続的に回動する方式でも良い。上記した実施例においては、バルブモータ６の駆動により可変部４８はこれの周方向に回動する回動式であるが、構造は図示はしないものの、可変部を直線的に往復移動させる直線移動式としても良い。
【００３４】
上記した実施例及び発明の実施の形態は本発明の例示であり、実施例、発明の実施の形態に記載した語句は、一部であっても請求項に記載できるものである。
【００３５】
【発明の効果】
本発明装置によれば、駆動源の駆動によりバルブが作動するため、拡散流給水路の水量と直線流給水路の水量との混合比が自動的に変更され、マイルドな『弱』の洗浄感、局所的な『強』の洗浄感、『中』の洗浄感が繰り返されることになり、人体の局部に対する良好なマッサージ効果が得られる。殊に拡散流を用いるため、直線流のみの水量の変化でマッサージ効果を得る場合に比較して、良好なるマッサージ効果が得られる。
【００３６】
本発明装置においては、ノズルの拡散流給水路の水量を増加させるときには直線流給水路の水量を減少させ、また、ノズルの拡散流給水路の水量を減少させるときには直線流給水路の水量を増加させるように、バルブが設けられている場合には、ノズルの噴出口から噴出される洗浄水の単位時間当たりの水量自体は基本的にはほぼ一定に維持されることが可能となる。この場合、拡散流の水量と直線流の水量との混合比の変更に基づくマッサージ効果を得つつも、人体局部に対する洗浄能力を低下させることなく洗浄能力を良好に確保することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a human body local cleaning apparatus that cleans the human body by ejecting cleaning water from a nozzle outlet to a local body part, and more particularly to a human body local cleaning apparatus that improves the massage effect.
[0002]
[Prior art]
The human body local cleaning device has a nozzle that jets cleaning water toward a local part of the human body to clean the local part. Furthermore, in recent years, as a human body local cleaning device that eliminates the monotonous feeling at the time of cleaning or has improved for people with hemorrhoids, etc., it can change the amount of water centered on the set amount of water ejected toward the local part of the human body. No. 3-10773, JP-B No. 3-16461), while giving a change in the amount of water centered around the set amount of water ejected toward the local area, at least once, regardless of the set amount of water There is known a technique (Japanese Patent Publication No. 3-10774) that ejects water and enhances the cleaning effect. In the devices according to these publications, a linear flow that is ejected linearly is ejected to a local part of the human body, and a massage effect on the local part of the human body is obtained by a change in the amount of water centered on a set value.
[0003]
[Problems to be solved by the invention]
However, although the human body local cleaning device according to the above-mentioned publication can obtain a certain amount of massage effect on the human body part due to the change in the amount of water, the cleaning water is ejected linearly toward the local part of the human body. Is not always sufficient and further development is desired.
[0004]
The present invention has been made in view of the above-described circumstances, and its problem is to mix a diffusion flow of washing water and a linear flow of washing water, and change the mixing ratio, thereby massaging the human body locally. It is an object of the present invention to provide a human body local cleaning device with an improved height.
[0005]
[Means for Solving the Problems]
(1) A human body local cleaning device according to the present invention of aspect 1 (Claim 1) has a cleaning mechanism that is mounted on a toilet and has a cleaning mechanism for cleaning the human body by spraying cleaning water from the outlet into the local body. In the cleaning device,
Cleaning mechanism includes a diffusion flow water supply passage to which the cleaning liquid to be diffusive flow Ru is diffused washing water flows, a nozzle with a linear flow water supply path wash water flows also becomes linear linear flow than the diffusion flow water supply path ,
A valve that is connected to the nozzle diffusion flow water channel and the straight flow water channel and can change the mixing ratio between the water amount of the nozzle diffusion flow water channel and the water flow of the linear flow water channel in accordance with the operation;
It is ejected from the nozzle outlet toward the local part of the human body by automatically changing the mixing ratio between the amount of water in the diffusion flow water supply channel and the amount of water in the straight flow water supply channel. And a drive source that changes the cleaning area of the cleaning water over time .
[0006]
In the first aspect of the present invention device, the valve changes the mixing ratio of the amount of water in the diffusion flow water supply channel of the nozzle and the amount of water in the linear flow water supply channel as the valve operates. The valves are operated automatically by the driving source. When the drive source is driven and the valve is operated as described above, the mixing ratio is automatically changed by the operation of the valve. As a result, in the wash water ejected from the nozzle outlet toward the human body part, the amount of diffusion flow increases or the amount of linear flow increases over time. When the amount of water in the diffusion flow increases, the washing area increases and a mild washing feeling is obtained. When the amount of water in the linear flow increases, the cleaning area is reduced and a strong local cleaning feeling can be obtained. When the ratio of the amount of water between the diffusion flow and the straight flow becomes intermediate, an intermediate feeling of cleaning is obtained.
[0007]
Since the valve is automatically actuated, the mixing ratio of the water volume of water and linear flow water supply path of the diffusion flow water supply channel is automatically changed by driving motion of the driving source in the present invention apparatus, as described above, mild A feeling of cleanness, a strong local feeling of cleaning, and an intermediate feeling of cleaning are repeated over time, and a massage effect on the local part of the human body is obtained.
[0008]
(2) The human body local cleaning device according to the present invention of aspect 2 (Claim 2) has a cleaning mechanism that is mounted on a toilet and has a cleaning mechanism that sprays cleaning water from a jet outlet onto a local part of the human body to clean the local part of the human body. In the cleaning device,

[0009]
In the present invention apparatus of aspect 2, the valve changes the mixing ratio between the amount of water in the diffusion flow water supply channel of the nozzle and the amount of water in the straight flow water supply channel as it operates. This valve is automatically actuated by a drive source.

DETAILED DESCRIPTION OF THE INVENTION
The present invention can employ at least one of the following forms.
・ Valve increases the amount of water in the diffusion flow water supply channel of the nozzle and decreases the amount of water in the straight flow water supply channel, and reduces the amount of water in the diffusion flow water supply channel of the nozzle and increases the amount of water in the straight flow water supply channel And can be switched to an intermediate form between the two. In this case, it is advantageous to keep the total water amount per unit time of the washing water ejected from the nozzle ejection port substantially constant. As a result, while changing the ratio of the diffusion flow and the ratio of the linear flow, the total amount of water per unit time can be ensured, and the reduction of the cleaning ability for the human body part can be suppressed. In some cases, the total amount of cleaning water ejected from the nozzle may be changed, and the total amount of cleaning water ejected from the nozzle may be increased or decreased as time progresses.
The valve has a first opening that communicates with the diffusion flow water supply channel, a second opening that communicates with the straight flow water supply channel, and a variable portion that makes the opening area of the first opening and the opening area of the second opening variable. The form can be adopted. For example, the first opening can be formed such that the opening width gradually increases in one direction and gradually decreases in the other direction. The second opening can be formed, for example, such that the opening width gradually decreases in one direction and gradually increases in the other direction. If the variable portion moves in one direction or the other direction, the opening area of the first opening and the opening area of the second opening can be made variable. In this case, since the valve is activated when the motor as the drive source is driven, the amount of the cleaning water supplied to the diffusion flow water supply channel and the amount of the cleaning water supplied to the linear flow water supply channel are automatically set. Can be variable. As a result, the mixing ratio of the amount of washing water supplied to the diffusion flow water supply channel and the amount of washing water supplied to the linear flow water supply channel can be automatically changed. The mixing ratio may be changed steplessly or may be changed stepwise.
A massage switch for driving a motor as a drive source for operating the valve can be provided. The massage switch may be incorporated in the cleaning switch that commands the start and end of cleaning, or may be provided separately from the cleaning switch.
-The nozzle can adopt the form which can face the local part of a human body, and has a spout which is common to both a diffusion flow water supply channel and a straight flow water supply channel. In this case, the washing water for the diffusion flow water supply channel and the washing water for the straight flow water supply channel are ejected from a common outlet. In this case, as compared with the case where the diffusion flow and linear flow are separately ejected from a dedicated jets respectively, advantageously with that Do to be favorably mixing the diffusion flow and linear flow.

[0015]
The nozzle 3 is for ejecting washing water to a local part such as an anus of the human body to wash the local part. The nozzle 3 is provided in the base 2 so as to be able to move forward and backward, that is, to be movable in the directions of arrows X1 and X2. By driving a nozzle motor (not shown), the nozzle 3 moves forward in the direction of the arrow X1 to clean the human body part. When is finished, it moves backward in the direction of arrow X2.
[0016]
FIG. 3 shows a longitudinal section near the tip of the nozzle 3. FIG. 4 shows a cross section taken along line IV-IV in FIG. FIG. 5 shows a cross-section along the line VV in FIG. As shown in FIG. 3, a diffusion flow water supply channel 31 and a straight flow water supply channel 32 run in parallel in the nozzle 3 in a substantially parallel manner. As shown in FIG. 5, the cross section of the nozzle 3 is an oval type. As shown in FIG. 5, the diffusion flow water supply channel 31 and the linear flow water supply channel 32 are formed in the nozzle 3 so that the cross section is a flat shape. As shown in FIG. 2, the valve 4 and the diffusion flow water supply channel 31 are connected by a first water channel 41, and the valve 4 and the linear flow water supply channel 32 are connected by a second water channel 42. Accordingly, the wash water is individually supplied to the diffusion flow water supply channel 31 and the straight flow water supply channel 32 through the valve 4.
[0017]
As shown in FIG. 3, one jet port 34 having a central axis P is formed on the surface 3 i on the side facing the local part of the human body among the tip side of the nozzle 3. The spout 34 communicates with both the diffusion flow water supply channel 31 and the straight flow water supply channel 32, and is common to both the diffusion flow water supply channel 31 and the straight flow water supply channel 32. Therefore, the jet nozzle 34 joins and discharges the wash water from the diffusion flow water supply channel 31 and the wash water from the straight flow water supply channel 32.
[0018]
As shown in FIG. 3, inside the nozzle 3, the diffusion flow water supply channel 31 is provided on the surface 3 i side facing the local part of the human body, and communicates with the spout 34. At the front end side of the diffusion flow water supply channel 31, a turning promotion portion 5 is formed that gives a turning effect to the cleaning water in the diffusion flow water supply channel 31. Inside the nozzle 3, the linear flow water supply channel 32 is provided on the back surface 3 s side facing the local part of the human body, and communicates with the diffusion flow water supply channel 31 and the jet port 34 through the communication port 37. The communication port 37, the jet port 34, and the swirl chamber 3 described later are arranged coaxially with respect to the central axis P of the jet port 34.
[0019]
As shown in FIG. 4, the swirl promoting unit 5 includes a wall body 52 having an outer wall surface 51 having a circular cross section, a swirl chamber 53 formed inside the wall body 52, a swirl chamber 53, and diffusion flow water supply. It has a plurality of slit-like through holes 54 that communicate with the passage 31 and supply the washing water that has flowed through the diffusion flow water supply passage 31 to the swirl chamber 53 . The through hole 54 is formed at a position offset with respect to the central axis P. The swirl chamber 53 has an arc wall surface 53m along an arc for promoting the swirling of the cleaning water. Wash water supplied to the diffusion flow water supply channel 31 at a predetermined water pressure enters the through hole 54 from the inlet 54 a of the through hole 54, and is discharged from the outlet 54 c of the through hole 54 to the swirl chamber 53. Then, it is ejected from the nozzle 34 to the outside of the nozzle 3. In FIG. 4, the flow of water is shown as an arrow. When flowing through the through hole 54 and the swirl chamber 53, swirling action is imparted to the cleaning water. Therefore, the washing water ejected from the ejection port 34 via the swirl chamber 53 has a small diameter on the ejection port 34 side, as shown schematically in FIG. The diameter becomes larger due to centrifugal force, and a diffusion water flow having a substantially conical shape is obtained. Since such a diffusing water flow has a large cleaning area, a mild cleaning feeling can be obtained as compared with the case of only a straight flow.
[0020]
FIG. 7 shows the valve 4. The valve 4 includes a first opening 44 that communicates with the diffusion flow water supply path 31, a second opening 46 that communicates with the linear flow water supply path 32, and a movable type that closes the openings of the first opening 44 and the second opening 46. And a variable portion 48. The variable portion 48 has a U-shaped opening groove 48x along the radial direction. When the valve motor 6 described above is driven, the variable portion 48 of the valve 4 rotates about the axis S thereof.
[0021]
As shown in FIG. 7, the first opening 44 has an arc shape, and the opening width increases as it goes in one direction in the circumferential direction, that is, in the direction of the arrow B1, and opens in the other direction in the circumferential direction, that is, in the direction of the arrow B2. The width is formed to be small. The second opening 46 has an arc shape and is formed such that the opening width decreases in one direction in the circumferential direction, that is, in the direction of the arrow B1, and the opening width increases in the other direction in the circumferential direction, that is, in the direction of the arrow B2. Has been. Accordingly, the first opening 44 and the second opening 46 have the opposite directions of the opening width.
[0022]
When the variable portion 48 rotates in one direction (arrow B1 direction) or the other direction (arrow B2 direction), the area where the first opening 44 and the opening groove 48x face each other changes. Similarly, the area where the second opening 46 and the opening groove 48x face each other changes. As a result, the opening area of the first opening 44 communicating with the diffusion flow water supply channel 31 and the opening area of the second opening 46 communicating with the linear flow water supply channel 32 can be continuously changed.
[0023]
In the present embodiment, when a user sitting on the toilet seat 12 operates the massage switch 1b, the signal is input to the control device 7, and the valve motor 6 is driven via the valve motor drive circuit 70. Thereby, the variable part 48 toward one direction (arrow B1 direction) or another direction (arrow B2 direction) rotates continuously around the axis S of this.
[0024]
When the variable portion 48 rotates in this way, the opening groove 48x of the variable portion 48 rotates, so that the amount of cleaning water supplied to the diffusion flow water supply channel 31 and the cleaning supplied to the linear flow water supply channel 32 are increased. The amount of water can be changed continuously. As a result, the mixing ratio of the amount of washing water supplied to the diffusion flow water supply channel 31 and the amount of washing water supplied to the linear flow water supply channel 32 can be changed steplessly. As a result, it is possible to periodically and continuously adjust the washing water ejected from the ejection port 34 to increase the linear flow or increase the diffusion flow. Accordingly, and Turkey continuously varying the diameter of the washing water released substantially conical shape from the ejection port 34 with the turning.
[0025]
Further description will be made with reference to FIG. That is, as shown in (i) of FIG. 7A, the opening groove 48x of the variable portion 48 is divided into a portion 44w having a large opening width of the first opening 44 and a portion 46n having a small opening width of the second opening 46. When communicating, the proportion of the amount of water in the diffusion flow increases and the proportion of the amount of water in the straight flow decreases. Accordingly, as shown in (ii) of FIG. 7A, the wash water ejected from the ejection port 34 of the nozzle 3 toward the human body part has a conical shape so that the diameter of the washing water increases as it is ejected far away. . Therefore, since the cleaning area increases, a mild “weak” cleaning feeling can be obtained.
[0026]
As shown in (i) of FIG. 7C, the opening groove 48x of the variable portion 48 communicates with a portion 44n having a small opening width of the first opening 44 and a portion 46w having a large opening width of the second opening 46. Sometimes, the proportion of the amount of water in the diffusion flow decreases and the proportion of the amount of water in the straight flow increases. Therefore, as shown in (ii) of FIG. 7 (C), the washing water ejected from the ejection port 34 of the nozzle 3 toward the human body part is ejected in a straight flow manner. Accordingly, since the cleaning area is reduced, a “strong” cleaning feeling can be obtained.
[0027]
As shown in (i) of FIG. 7B, the opening groove 48x of the variable portion 48 is divided into a portion 44m in the middle of the opening width of the first opening 44 and a portion 46m in the middle of the opening width of the second opening 46. When communicating, the amount of water in the diffusion flow and the amount of water in the straight flow are the same. Accordingly, as shown in (ii) of FIG. 7B, the wash water ejected from the jet port 34 of the nozzle 3 toward the human body local portion becomes a moderate jet water, and a “medium” washing feeling is obtained.
[0028]
In this embodiment, when the user turns on the massage switch 11b, the valve motor 6 is driven, and the variable portion 48 of the valve 4 continuously reciprocates in the direction of arrow B1 or arrow B2. “Weak”, “Medium”, and “Strong” are repeated, so that the massage process for the local part of the human body can be performed satisfactorily, which is particularly suitable for use by people with hemorrhoids.
[0029]
By the way, in the above-described prior art, in order to perform the massage process, as described above, a method of changing the water amount centering on the set water amount ejected toward the local part of the human body is employed. In the case of this method, there is a problem that the cleaning ability is lowered when the amount of water decreases from the set amount of water. In this embodiment, the valve 4 decreases the amount of water in the linear flow water supply channel 32 when increasing the amount of water in the diffusion flow water supply channel 31. Further, the valve 4 increases the amount of water in the straight flow water supply channel 32 when the amount of water in the diffusion flow water supply channel 31 is decreased. For this reason, in this embodiment, the amount of water supplied to the nozzle 3 per unit time is maintained substantially constant. Therefore, in the present embodiment, the amount of water per unit time of the cleaning water ejected from the nozzle 34 of the nozzle 3 while obtaining a massage effect by changing the mixing ratio of the amount of diffusion flow and the amount of linear flow. Since it itself is basically kept constant, it can be ensured satisfactorily without deteriorating the cleaning ability for the local part of the human body.
[0030]
In addition, in the present embodiment, as shown in FIG. 5, the cross-sectional shapes of the diffusion flow water supply channel 31 and the straight flow water supply channel 32 are flat, so that the diffusion flow water supply channel 31 and the linear flow water supply channel 32. Can be arranged in the nozzle 3 in a compact manner, and the enlargement of the nozzle 3 can be prevented.
[0031]
Further, in this embodiment, the washing water for the diffusion flow water supply channel 31 and the washing water for the straight flow water supply channel 32 are ejected from the ejection port 34 common to both. In this case, compared with the case where the diffusing flow and the linear flow are individually ejected from independent jets, it is advantageous for mixing the diffusing flow and the linear flow well and is mild without reducing the amount of water. A feeling of cleaning can be obtained, and a good massage effect can be ensured also in this sense.
[0032]
FIG. 8 shows a typical flowchart of a subroutine of massage processing executed by the microcomputer of the control device 7. As shown in FIG. 8, in step S102, the microcomputer of the control device reads the massage switch 1b and determines whether or not the massage switch 1b is turned on. If the massage switch 1b is on, the process proceeds to step S104, and the valve 4 that drives the valve motor 6 is opened and closed. In step S106, the massage switch 1b is read to determine whether the massage switch 1b is off. If the massage switch 1b is off, the valve motor 6 is stopped, other processing is performed in step S110, and the process returns to the main routine. If the massage switch 1b is turned on as a result of the determination in step S106, the process returns to step S104 and the drive of the valve motor 6 is continued. As a result, the valve motor 6 continues to be driven and the valve 4 continues to operate until the massage switch 1b is turned off, so that “weak”, “medium”, and “strong” of the washing water are repeated, and massage is performed on the local part of the human body. The effect can be performed satisfactorily. The above-described flowchart is an example, and the present invention is not limited to this.
[0033]
In addition, the present invention is not limited to the embodiments described above and shown in the drawings, and can be implemented with appropriate modifications within a range not departing from the gist. For example, the number of through holes 54 in the turning promotion portion 5 is not limited to a plurality, and may be one. Moreover, the turning promotion part 5 is not limited to the above-mentioned thing, You may have an impeller etc. for turning washing water. Further, the valve 4 is not limited to the above-described mechanism, and any valve may be used as long as it has a function of changing the mixing ratio between the water amount of the diffusion flow water supply channel 31 and the linear flow water supply channel 32 and the water amount in the nozzle 3. In the above-described embodiment, the variable portion 48 is reciprocally rotated by a predetermined distance along the circumferential direction thereof by driving the valve motor 6. However, the present invention is not limited to this, and the movable portion of the valve may be a circumferential direction. Alternatively, a continuous rotation method may be used. In the above-described embodiment, the variable portion 48 is a rotary type that rotates in the circumferential direction by driving the valve motor 6, but the structure is not shown, but the linear movement that linearly reciprocates the variable portion. It may be an expression.

[0035]
【The invention's effect】
According to the device of the present invention, since the valve is operated by driving the drive source , the mixing ratio between the amount of water in the diffusion flow water channel and the amount of water in the straight flow water channel is automatically changed, and a mild “weak” cleaning feeling is obtained. The local “strong” washing feeling and the “medium” washing feeling are repeated, and a good massage effect on the local part of the human body is obtained. In particular, since a diffusion flow is used, a better massage effect can be obtained as compared with a case where a massage effect is obtained by changing the amount of water only in a straight flow.
[0036]
In the device of the present invention, when increasing the amount of water in the diffusion flow water supply channel of the nozzle, the amount of water in the straight flow water supply channel is decreased, and when decreasing the amount of water in the diffusion flow water supply channel of the nozzle, the amount of water in the linear flow water supply channel is increased. so as to, when the valve is provided, water itself per unit of the washing water time that is ejected from the ejection port of the nozzle it is possible for basically is maintained substantially constant. In this case, while obtaining a massage effect based on a change in the mixing ratio between the amount of water in the diffusive flow and the amount of water in the linear flow, the washing ability can be ensured satisfactorily without reducing the washing ability with respect to the local body part.
