Description

【０００１】
【発明の属する技術分野】
本発明は、便器に据付けられ人体局部の温水洗浄を行う衛生洗浄装置に関する。
【０００２】
【従来の技術】
従来、人体局部の温水洗浄を行う衛生洗浄装置において、満水検出手段が満水と検知するまで給水制御手段を給水状態としている。
これは、衛生洗浄装置の施工時や、洗浄水貯留手段の水抜き操作の後に再度使用する際、電源投入してから洗浄水貯留手段を自動的に満水化するためである。
【０００３】
その一方で、洗浄水貯留手段を自動的に満水化するに際して、以下のような不都合を生じていた。
【０００４】
移動体、例えばキャンピングカー等に設置されている衛生洗浄装置の場合、夏場の炎天下に駐車していると、温水洗浄装置に接続される配管内の水が高温になり、たとえ洗浄水貯留手段の水を抜いていたとしても、満水化する過程で高温の水が洗浄水貯留手段内に流入し、洗浄水温度検知手段からの信号によって、制御手段が安全のために衛生洗浄装置の洗浄機能を使用不可にしてしまうことになる。
【０００５】
【発明が解決しようとする課題】
しかしながら、移動体のエアコン等の冷却手段によって、移動体内の温度が常温になり、衛生洗浄装置の洗浄水貯留手段内の水温が適温になったとしても、衛生洗浄装置は洗浄機能が使用不可となったままであり、使用者が衛生洗浄装置の電源をリセットする等、洗浄機能の使用不可状態の解除を行う必要があるため、使用者に不便であった。
【０００６】
本発明は、この様な課題を解決するためのものであり、衛生洗浄装置の電源投入後の一時的な高温状態による洗浄機能使用不可を自動的に解除することによって、使用者の手を煩わせることなく洗浄機能使用不可状態を解除する衛生洗浄装置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】
上記問題を解決するため、請求項１は、洗浄水を貯留する洗浄水貯留手段と、前記洗浄水貯留手段の満水を検知する満水検出手段と、給水口からの前記洗浄水貯留手段への給水を制御する給水制御手段と、給水口からの洗浄水の温度を検知する洗浄水温度検知手段と、前記満水検出手段の出力に応じて前記給水制御手段を制御し、また、前記洗浄水温度検知手段が設定値以上の高温を検知すると給水を停止する制御手段とを有する衛生洗浄装置において、給水によって前記洗浄水貯留手段が満水となったことを前記満水検出手段が検知した際に前記洗浄水温度検知手段による検知温度が設定値以上の高温である場合には、前記満水検出手段が満水と検知した後も一定時間給水状態にして、前記満水検出手段から高温の水を排水することを特徴とする。これにより、移動体内の配管の一部で熱せられた高温の水が衛生洗浄装置の洗浄水貯留手段内に流入しても、一定時間給水して、前記洗浄水貯留手段から高温の水を排水し続けるため、洗浄水温度検知手段からの信号によって、制御手段が安全のために衛生洗浄装置の洗浄機能を使用不可にしてしまうことがないようにすることができる。
【０００８】
また、請求項２は、洗浄水を貯留する洗浄水貯留手段と、前記洗浄水貯留手段の満水を検知する満水検出手段と、給水口からの前記洗浄水貯留手段への給水を制御する給水制御手段と、給水口からの洗浄水の温度を検知する洗浄水温度検知手段と、前記満水検出手段の出力に応じて前記給水制御手段を制御し、また、前記洗浄水温度検知手段が設定値以上の高温を検知すると給水を停止する制御手段とを有する衛生洗浄装置において、給水によって前記洗浄水貯留手段が満水となったことを前記満水検出手段が検知した際に前記洗浄水温度検知手段による検知温度が設定値以上の高温である場合には、前記満水検出手段が満水と検知した後も前記洗浄水温度検知手段の検知温度が第２の設定値以下になるまで給水状態にして、前記洗浄水貯留手段から高温の水を排水することを特徴とする。これにより、移動体内の配管の一部で熱せられた高温の水が衛生洗浄装置の洗浄水貯留手段内に流入しても、洗浄温度検知手段の検知温度が第２に設定された値となるまで給水して、前記洗浄水貯留手段から高温の水を排水し続けるため、制御手段が安全のために衛生洗浄装置の洗浄機能を使用不可にしてしまうことがないようにできる。
【０００９】
また、請求項３は、請求項２に記載の衛生洗浄装置において、洗浄水温度検知手段の検知温度が、設定された値以下にならなくても、設定された一定時間経過後に給水状態を停止することを特徴とする。これにより、移動体内の配管の一部で熱せられた高温の水が衛生洗浄装置の洗浄水貯留手段内に流入し、洗浄温度検知手段の検知温度が設定値以下とならなくても、一定時間で給水を停止するため、移動体内の多量の水を無駄に捨てることがないようにすることができる。
【００１０】
【発明の実施の形態】
本発明の内容をより理解しやすくするため、以下に実施例を用いて詳説する。図１に本発明に係わる衛生洗浄装置の要部ブロック構成図を示す。図１において、洗浄水を供給する給水配管には、上流側から順に、給水部１、フィルタ２、逆止弁３、調圧弁４が接続されている。調圧弁４の下流は、流路の通水を制御する電磁弁７に接続されている。電磁弁７の下流は、安全弁８を介して温水タンク９へ接続されている。また、温水タンク９内には、温水ヒータ１０及び、満水を検知するためのフロートＳＷ１１、及び温水タンク内の温度を検知するための温水サーミスタ１６が設けられている。通常、フロートＳＷ１１は磁気を検出してＯＮ／ＯＦＦするリードＳＷがもちいられる。
【００１１】
また、温水タンク９の下流には、バキュームブレーカ１２が接続され、さらに流路切替兼流量調整弁１３が接続されている。流路切替兼流量調整弁１３の下流は、洗浄水を人体へ噴出するノズル装置１４へ接続されている。また、ノズル装置１４には、おしり洗浄流路、やわらか洗浄流路、ビデ洗浄流路の３つの流路が構成されており、制御手段５からの指示により適宜流路を切り替えることができる。
【００１２】
上記の構成により、電磁弁７の開動作により給水部１から供給された洗浄水は、温水タンク９により適温の湯に加熱され、バキュームブレーカ１２を押し上げ、流路切替兼流量調整弁１３へと至る。ここで洗浄水は、流路切替兼流量調整弁１３により流量調節され、選択された流路を通り、ノズル装置１４から噴出されるのである。
【００１３】
また、制御手段５は、着座検出手段６からの信号を受けて制御している。ここでは、着座検出手段６は光電反射式センサーを記載している。着座検出手段６は赤外線を投光して、対象物（人体）からの反射光のレベルで対象物の有無を判断して制御手段５に出力している。
【００１４】
さらに、制御手段５は、着脱検出手段１５からの信号を受けて制御している。ここでは、着脱検出手段１５は普通、衛生洗浄装置と便器との取付け機構で構成されている。着脱検出手段１５は衛生洗浄装置と便器との取付け面に突起したマイクロＳＷ等で、衛生洗浄装置が便器から離脱され、便器面から浮き上がるとＯＦＦするような構造で構成される。（詳細略）
【００１５】
図２に本発明の請求項１にかかる制御内容をフローチャートで示している。ここでは満水検出手段をフロートスイッチとし、洗浄水温度検知手段をサーミスタとし、給水制御手段を電磁弁として、電磁弁ＯＮを給水開始、電磁弁ＯＦＦを給水停止としている。まず、電源投入後、（Ｓ１）でフロートＳＷのＯＮ／ＯＦＦ判断を行う。そこで（Ｓ２）でフロートＳＷがＯＦＦなら、電磁弁ＯＮで給水を開始させ、フロートＳＷがＯＮになるまで給水を継続する。また（Ｓ１）でフロートＳＷがＯＮなら、（Ｓ３）でタイマをスタートさせ時間を計測開始してから、（Ｓ４）でサーミスタの温度が設定値より高ければ、（Ｓ５）でタイマのカウントが設定値になった後に、（Ｓ６）で電磁弁をＯＦＦし給水を停止して、洗浄待機状態に移る。また、（Ｓ４）でサーミスタの温度が設定値より低ければ、（Ｓ６）で電磁弁をＯＦＦし給水を停止して、洗浄待機状態に移る。これにより、電源投入時に自動給水を行い、温水タンクが満水化された後に、サーミスタの温度が設定値より高い場合のみ、一定時間給水を続けることで高温の水を排水することができる。
【００１６】
図３に本発明の請求項２にかかる制御内容をフローチャートで示している。ここでは満水検出手段をフロートスイッチとし、洗浄水温度検知手段をサーミスタとし、給水制御手段を電磁弁として、電磁弁ＯＮを給水開始、電磁弁ＯＦＦを給水停止としている。まず、電源投入後、（Ｓ１１）でフロートＳＷのＯＮ／ＯＦＦ判断を行う。そこで（Ｓ１２）でフロートＳＷがＯＦＦなら、電磁弁ＯＮで給水を開始させ、フロートＳＷがＯＮになるまで給水を継続する。また（Ｓ１１）でフロートＳＷがＯＮなら、（Ｓ１３）でサーミスタの温度が設定値より高ければ、設定値より低くなるまで給水を継続し、（Ｓ１４）で電磁弁をＯＦＦし給水を停止して、洗浄待機状態に移る。これにより、電源投入時に自動給水を行い、温水タンクが満水化された後に、サーミスタの温度が設定値より高い場合のみ、給水を続けることで高温の水を排水することができる。
【００１７】
次に、図４に本発明の請求項３にかかる制御内容を示す。ここでは満水検出手段をフロートスイッチとし、洗浄水温度検知手段をサーミスタとし、給水制御手段を電磁弁として、電磁弁ＯＮを給水開始、電磁弁ＯＦＦを給水停止としている。まず、電源投入後、（Ｓ２１）でフロートＳＷのＯＮ／ＯＦＦ判断を行う。そこで（Ｓ２２）でフロートＳＷがＯＦＦなら、電磁弁ＯＮで給水を開始させ、フロートＳＷがＯＮになるまで給水を継続する。また（Ｓ２１）でフロートＳＷがＯＮなら、（Ｓ２３）でタイマをスタートさせ時間を計測開始してから、（Ｓ２４）でサーミスタの温度が設定値より低ければ、（Ｓ２６）で電磁弁ＯＦＦで給水を停止し、洗浄待機状態となる。また、（Ｓ２４）でサーミスタの温度が設定値より高ければ、（Ｓ２５）でタイマのカウントが設定時間となるか、サーミスタの温度が設定温度になるまで給水を継続する。これにより、電源投入時に自動給水を行い、温水タンクが満水化された後に、サーミスタの温度が設定値より高い場合は給水を継続するが、一定時間経過すると給水を停止するので、多量の無駄な水を捨てることがなくてすむ。
【００１８】
以上のようにして、衛生洗浄装置を制御させることで、衛生洗浄装置の電源投入後の一時的な高温状態による洗浄機能使用不可を自動的に解除することによって、使用者の手を煩わせることなく洗浄機能使用不可状態を解除することができるのである。
【００１９】

【００２１】
請求項２では、衛生洗浄装置に通電された際に、一時的に高温の水が給水された場合は、温水タンクが満水となった後も設定温度より低い値になるまで給水を継続することで、一時的な高温の水を排水し、洗浄機能を使用不可としてしまうことがないようにすることができる。
【００２２】
請求項３では、衛生洗浄装置に通電された際に、一時的に高温の水が給水された場合は、温水タンクが満水となった後も設定温度より低い値になるまで給水を継続するが、それまでに一定時間が経過すれば給水を停止し、多量の無駄な水を捨てることがないようにすることができる。
