Description

【００２４】
ここで、表１は、便座１１の開閉状態、便座スイッチ１３、止水用バルブ５５、第１バルブ６１、第２バルブ６２の作動関係を示す。表１のＮｏ．１に示すように、便座１１が開放されているときには、便座スイッチ１３がオン、止水用バルブ５５がオン、第１バルブ６１がオン、第２バルブ６２がオフとなり、タイマ７６はオフである。また、表１のＮｏ．２に示すように、尿のため開放していた便座１１が閉鎖された直後では、便座スイッチ１３がオフ、止水用バルブ５５がオン、第１バルブ６１がオフ、第２バルブ６２がオンとなり、タイマ７６がオンとなる。また、表１のＮｏ．３に示すように、便座１１が閉鎖され続けている通常の状態では、便座スイッチ１３がオフ、止水用バルブ５５がオフ、第１バルブ６１がオフ、第２バルブ６２がオフとなり、タイマ７６がオフとなる。
【００２５】
更に使用について説明を加える。便座１１が閉鎖され続けている通常の状態では、表１のＮｏ．３に示すように、便座スイッチ１３がオフ、止水用バルブ５５がオフ、第１バルブ６１がオフ、第２バルブ６２がオフとなり、タイマ７６がオフとなる。このため吐水栓５４からタンク５０への給水は停止されており、第１通水路６０から給水口４７への給水、第２通水路６０から洗浄口４５への給水は停止されている。このため可動ロッド部２１は付勢バネ２２の付勢力により矢印Ａ２方向に退避位置Ｐ２に付勢されており、図２に仮想線で示すように、保持部材２の可動本体２０の取付具２３は第２ストッパ部４４に接近または接触している。この結果、図２に仮想線で示すように、目標部３は退避箇所Ｍ２に退避しており、目標部３の上面は洗浄口４５に対面している。目標部３が退避箇所Ｍ２に退避しているとき、目標部３は主筒４０のカバー部４０ｐにより覆われている。
【００２６】
なお、本実施例に係る便座装置１は、人体の局部（肛門等）を洗浄処理する洗浄ノズル１８を基部１０に有する。
【００２７】
図６は制御系のブロック図を示す。図６に示すように、便座スイッチ１３の信号、洗浄ノズル１８を作動させる洗浄スイッチ７７の信号、後述のキャンセルスイッチ７８の信号、後述の音響キャンセルスイッチ７９の信号は、制御装置１００に入力される。制御装置１００からの指令信号は止水用バルブ５５の駆動回路５５ｗ、第１バルブ６１の駆動回路６１ｗ、第２バルブ６２の駆動回路６２ｗ、スピーカ駆動回路７１、洗浄ノズル１８の駆動回路１８ｗ、タイマ７６の駆動回路７６ｗに出力され、これにより止水用バルブ５５、第１バルブ６１、第２バルブ６２、スピーカ７０、洗浄ノズル１８、タイマ７６が制御される。なおタイマ７６はマイコンの内部タイマとすることもできる。
【００２８】
次に、使用者（主として男性）が便器９内において放尿するときについて説明を加える。この場合には、便蓋１２、便座１１を持ち上げて開放させる。使用者自身により、あるいは、使用者を検知した信号に応じて図略の開閉機構が便蓋１２、便座１１を持ち上げて開放させる。このように便座１１が開放されると、便座スイッチ１３が便座１１の開放を検知する。すると、制御装置１００は、表１のＮｏ．１に示すように、止水用バルブ５５をオンし、第１バルブ６１をオン、第２バルブ６２をオフにする。これにより吐水栓５４からの水がタンク５０に給水されると共に、タンク５０内の水は第１通水路６０ｂ、給水口４７を経て主筒４０の水室４１に供給される。
【００２９】
この結果、水室４１の水圧により、付勢バネ２２の付勢力に抗して可動ロッド部２１が矢印Ａ１方向に前進し使用位置Ｐ１に向けて移動し、可動本体２０が第１ストッパ部４３に当たった位置で可動ロッド部２１は停止する。この状態では、目標部３は目標箇所Ｍ１に設定されている。この場合、図１に示すように、目標部３は便器９内に突出すると共に、便器９内に貯留されている水の水面ＷＡよりも上方に位置している。このように放尿の目標が便器９内に設定されているため、使用者は自然と目標部３に命中させようと放尿することになり、尿が便器９外方に飛び散ることが抑制される。殊に、使用者が子供のときに有効である。このため、床面等といった便器９周辺への尿の飛散が抑制され、トイレの清潔性を向上させることができる。殊に目標部３は、尿の飛散を抑制する緩衝性を有する緩衝部３２を有するため、目標部３における尿の跳ね返りが抑制され、便器９周辺への尿の飛散が抑制され、トイレの清潔性を向上させることができる。
【００３０】
目標部３に尿が当たったとしても、水室４１には水が供給されているため、保持部材２の可動ロッド部２１が矢印Ａ２方向に後退することは抑えられている。従って水が供給された水室４１は、目標部３に尿が当たったとき、保持部材２の可動ロッド部２１が後退することを抑える後退抑制手段として機能することができる。更に図２に示すように、保持部材２の可動ロッド部２１は、主筒４０のうち可動ロッド部２１の外径と相応する内径をもつ受け部４０ｔで支持されていると共に、保持部材２の可動本体２０が水室４１の内壁面の拘束面４１ｔに対面して拘束されているため、尿が目標部３に衝撃的に当たったとしても、保持部材２の可動ロッド部２１の揺動は抑えられている。従って、受け部４０ｔ及び拘束面４１ｔは、目標部３に尿が衝撃的に当たったとき、保持部材２の可動ロッド部２１の揺動を拘束する拘束手段として機能することができる。
【００３１】
本実施例によれば、尿が目標部３に当たったとき、目標部３に搭載したセンサ７４によりこの衝撃力を検知する。センサ７４の検知信号は制御装置１００に入力され、制御装置１００は、音響発生部７のスピーカ駆動回路７１を駆動させ、スピーカ７０から音響を鳴らす。音響としては音楽、水流音、格言、放尿に対する助言、動物の鳴き声等を採用することができる。即ち、制御装置１００に搭載されている記憶手段として機能するメモリ１０２のエリアには、音響として、複数の音楽（ａ１，ａ２…）、複数の水流音（ｂ１，ｂ２…）、複数の格言（ｃ１，ｃ２…）、放尿動作に対する複数の助言（ｄ１，ｄ２…）、複数の動物の鳴き声（ｅ１，ｅ２…）がそれぞれ格納されている。従って、使用者は、基部１０の操作パネルに装備されている選択スイッチ７５により音楽、水流音、格言、放尿に対する助言、動物の鳴き声のいずれかを使用者の好みに応じて選択することができる。音響が放尿動作に対する助言であれば、この助言に従って放尿動作をすれば、使用者が幼児であっても、尿の飛散を防止するのに有利となる。
【００３２】
このように尿が目標部３に当たっているとき、音響がスピーカ７０から鳴るため、その音響を聞きながら放尿でき、気分が爽快となったり、気ばらしにもなる。更に、尿が便器９内の水に当たる不快音も音響によって軽減または解消できるため、狭い室内においても他人に気兼ね無く放尿でき、環境上有利となる。
【００３３】
また上記したように尿が目標部３に当たっているとき、音響がスピーカ７０から鳴るため、尿が目標部３に当たっていないときには、その音響を中断させたり、音響の種類を変更させたりすれば、暗がり時においても、尿が目標部３に当たっていないことが認識されるため、便器９内に対する放尿の方向性を高めるのに貢献することができる。
【００３４】
更に放尿後には、便座１１が便蓋１２と共に閉鎖される。この場合、使用者自身により、あるいは、トイレからの使用者の退室を検知した信号に応じて図略の開閉機構が便蓋１２、便座１１を開放させる。表１のＮｏ．２に示すように、開放していた便座１１が閉鎖されるため、便座スイッチ１３がオフとなり、止水用バルブ５５のオンが維持され、第１バルブ６１がオフとなり、第２バルブ６２がオンとなり、タイマ７６がオンとなり、タイマ作動を開始する。タイマ７６は第２バルブ６２のオン時間を規定するものであり、タイマ設定時間の間、第２バルブ６２のオンは維持される。
【００３５】
このように便座１１の閉鎖に伴い第１バルブ６１がオフとなるため、止水栓５４の水はタンク５０に供給されるものの、タンク５０の水は給水口４７には供給されない。このように第１バルブ６１がオフとなると、ドレン通路６３が開放される。このため水室４１の水は、付勢バネ２２で付勢されている可動本体２０により矢印Ｅ１方向（図２参照）に押し返される。つまり、水室４１の水の圧力よりも付勢バネ２２の付勢力が打ち勝ち、水室４１の水はドレン通路６３を経て排水口から排出されると共に、付勢バネ２２によりピストン状の可動本体２０及び可動ロッド部２１は矢印Ａ２方向に移動して退避位置Ｐ２となり、目標部３が退避箇所Ｍ２に退避される。このように保持部材２が退避位置Ｐ２に退避すると共に、目標部３が退避箇所Ｍ２に退避されるとき、目標部３の上面は洗浄口４５に対面する。このとき止水用バルブ５５及び第２バルブ６２がオンとなっているため、止水栓５４の水はタンク５０に供給され、更にタンク５０の水は第２バルブ６２、第２通水路６０ｃを経て洗浄口４５に供給され、ひいては、洗浄口４５から吐出される水により目標部３は洗浄される。これにより目標部３の汚れが取り除かれる。尿は主として目標部３の上面にかかるが、洗浄用の水を吐出する洗浄口４５は目標部３の上面に対面するため、目標部３の上面の清掃に有利である。
【００３６】
タイマ７６の設定時間がオフとなるまで、第２バルブ６２のオンは維持されるため、タイマ７６の設定時間がオフとなるまで、目標部３の洗浄は実行される。従って、タイマ７６は、目標部３を洗浄する洗浄時間を設定する洗浄時間設定手段として機能できる。目標部３に対する洗浄能力を可変とするため、タイマ７６の設定時間は調整可能とすることができる。タイマ７６の設定時間がオフとなると、止水用バルブ５５、第２バルブ６２はオフとなり、目標部３の洗浄処理は終了する。このように尿が当たる目標部３は、尿が終了して便座１１、便蓋１２が閉鎖される都度、洗浄口４５から吐出される水によって目標部３は洗浄されるため、目標部３０を衛生的に維持できる。
【００３７】
本実施例によれば、前述の記載から理解できるように、タンク５０の水は、第１通水路６０ｂを介して保持部材２を使用位置Ｐ１に移動するため給水口４７に供給されると共に、第２通水路６０ｂを介して目標部洗浄部である洗浄口４５に洗浄用の水として供給される。このためタンク５０の水は、保持部材２を使用位置Ｐ１に移動させる用途と、尿で汚れた目標部３を洗浄させる用途とに共用されており、しかも双方の用途の使用タイミングは基本的には同一ではなく、時間的にずれているため、タンク５０の数、タンク５０のタンク容積を減少させるのに貢献できる。本実施例によれば、便座１１を開放されると自動的に保持部材２が使用位置Ｐ１に前進して目標部３が目標箇所Ｍ１に設定されている。従って便座１１を上方に回動させて便座１１を開放していない限り、保持部材２が使用位置Ｐ１に前進しないため目標部３が便器９内の目標箇所Ｍ１に突出されない。即ち、便座１１が下方に回動して閉鎖されているときには、目標部３が便器９内の目標箇所Ｍ１に突出されない。故に、下方に回動して閉鎖されている便座１１の上に使用者の腰部が載って使用者が排便するときには、保持部材２が使用位置Ｐ１に前進せず、ひいては目標部３が便器９内の目標箇所Ｍ１に突出されず、退避箇所Ｍ２に退避しており、従って便が保持部材２や目標部３に接触することが抑えられ、便による保持部材２や目標部３の汚れを未然に防止することができる。
【００３８】
本実施例によれば前述したように、便座１１が開放されると、水室４１内の水圧により自動的に保持部材２が矢印Ａ１方向に前進して使用位置Ｐ１に移動するが、この動作をキャンセルするキャンセル手段として機能するキャンセルスイッチ７８が基部１０の操作パネルに設けられている。即ち、キャンセルスイッチ７８は、放尿のために便座１１を開放したとして、保持部材２を使用位置Ｐ１に移動させず、ひいては目標部３を目標箇所Ｍ１に移動させないものである。
【００３９】
従ってキャンセルスイッチ７８を操作すれば、第１バルブ６１はオフとされ、水室４１に水が給水されないため、便座１１を開放したとしても保持部材２が使用位置Ｐ１に前進せず、退避位置Ｐ２に退避したままに維持される。このため、便座１１を開放したとしても、付勢バネ２２によりピストン状の可動本体２０及び可動ロッド部２１は矢印Ａ２方向に移動して退避位置Ｐ２となり、目標部３が退避箇所Ｍ２に退避された状態に維持される。故に便器９内の清掃時にはキャンセルスイッチ７８を清掃者が操作すれば、目標部３が便器９内に突き出さず、目標部３が便器９内の清掃の邪魔になることを防止でき、便利である。
【００４０】
上記した実施例の通常の制御則によれば、前述したように尿が目標部３に当たったとき、これをセンサ７４により検知し、センサ７４の検知信号は制御装置１００に入力され、制御装置１００は音響発生部７のスピーカ駆動回路７１を駆動させ、スピーカ７０から音響を鳴らすことにしている。更に、スピーカ７０から音響を鳴らすことを中止する音響キャンセル手段としての音響キャンセルスイッチ７９が基部１０の操作パネルに設けられている。従って、夜間等のように静粛性が要請される場合等には、必要に応じて音響キャンセルスイッチ７９を使用者が操作し、スピーカ７０から音響を鳴らすことを中止することもできる。
【００４１】
（第２実施例）
第２実施例は第１実施例と基本的には同様の構成、同様の作用効果を有する。以下、第１実施例と異なる部分を中心として説明する。図７は本実施例の制御則を示す。本実施例によれば、尿が目標部３に当たる度合に応じて音響を発生させる。使用者がした尿が目標部３の中心域に当たる命中率を制御装置１００が求め、命中率に応じて音響の種類を変更する。尿が目標部３の中心域に当たる命中率は、センサ７４が検知する衝撃力の大きさ、あるいは、センサ７４が検知する衝撃の時間によって判定する。この制御則を規定するフローチャート（図７参照）は、便座が開放されて便座スイッチ１３が操作されると共に起動する。即ち、図７に示すように、初期設定（ステップＳ１０２）後に、センサ７４の信号を所定回数読み込む（ステップＳ１０４，ステップＳ１０６）。そして、制御装置１００は、目標部３に対する尿の命中率を求める（ステップＳ１０８）。従って、ステップＳ１０８は、目標部３に対する尿の命中率を演算する演算手段として機能できる。
【００４２】
命中率が相対的に低いとき（目標部３に対して外れているときも含む）には、制御装置１００は、第１音響を発生させる信号をスピーカ駆動回路７１に出力する（ステップＳ１１０，ステップＳ１１２）。命中率が相対的に中程度のときには第２音響を発生させる信号をスピーカ駆動回路７１に出力する（ステップＳ１１４，ステップＳ１１６）。また命中率が相対的に高いときには第３音響を発生させる信号をスピーカ駆動回路７１に出力する（ステップＳ１１８，ステップＳ１２０）。センサ７４が検知する命中率が極めて高いときには第４音響を発生させる信号をスピーカ駆動回路７１に出力する（ステップＳ１２２）。音響の過度の変更を防止すべく、ステップＳ１２４において所定時間待機し、便座１１が閉鎖されていなければ、放尿が継続されている可能性が高いため、ステップＳ１０４に戻る。また便座１１が閉鎖されていれば、放尿が終了しているため、制御装置１００は、音響停止信号を出力し（ステップＳ１２６，ステップＳ１２８）、制御を終了する。ステップＳ１２６，ステップＳ１２８は、音響を停止させる音響停止手段として機能できる。また便座１１の開放が継続したとしても所定時間経過すれば、使用者が便座１１の閉鎖動作を忘れたことが推定されるため、音響停止信号を出力し（ステップＳ１３０，ステップＳ１２８）、制御を終了する。
【００４３】
第１音響〜第４音響としては音楽、水流音、格言、放尿に対する助言、動物の鳴き声等を採用することができ、命中率の高低関係を識別できるように命中率の高低関係を明示または暗示する音響を採用することができる。従って、第１音響は、命中率が低いことを明示または暗示する音響とする。第２音響は、命中率が中程度であることを明示または暗示する音響とする。第３音響は、命中率が高いことを明示または暗示する音響とする。第４音響は、命中率が極めて高いことを明示または暗示する音響とする。
【００４４】
本実施例においても、尿が目標部３に当たっているときに音響が発生され、その音響を聞きながら放尿できるため、気分が爽快となったり、気ばらしにもなる。更に、尿が目標部３に当たる度合い（命中率）に応じて、音響が発生されるため、気分が一層爽快となったり、気ばらしにもなり、更に、尿を目標部３に命中させようとする使用者の意識を高めることができ、楽しみつつ放尿できるばかりか、便器９周辺への尿の飛散が一層抑制され、トイレの清潔性を更に向上させることができる。
【００４５】
（第３実施例）
図８は第３実施例を示す。第３実施例は第１実施例と基本的には同様の構成、同様の作用効果を有する。以下、第１実施例と異なる部分を中心として説明する。図８に示すように、センサ７４Ｂを可動ロッド部２１のうち目標部３と反対側の部位に搭載している。この場合、尿がかかる目標部３からセンサ７４Ｂを遠ざけることができる。可動ロッド部２１に先端部の目標部３に尿がかかると、この衝撃力がモーメントとして可動ロッド部２１のうち目標部３と反対側の部位に作用するため、これをセンサ７４Ｂが検知することができる。従って、この検知信号を制御装置１００に入力させて音響発生部７のスピーカ駆動回路７１を駆動させ、スピーカ７０を鳴らす。
【００４６】
（第４実施例）
図９は第４実施例を示す。第４実施例は第１実施例と基本的には同様の構成、同様の作用効果を有する。以下、第１実施例と異なる部分を中心として説明する。可動機構４の主要素である主筒４０は、目標部３の向きを調整する調整機構として機能できる回動部９２に矢印Ｒ１，Ｒ２方向に回動可能に設けられている。回動部９２は駆動モータまたは手動操作により回動可能とされている。使用者の好み、使用者の身長（子供、大人）等に応じて、回動部９２の回動作用により、主筒４０の向きを調整でき、便器９に対する目標部３の向きを調整することができる。
【００４７】
（第５実施例）
図１０は第５実施例を示す。第５実施例は第１実施例と基本的には同様の構成、同様の作用効果を有する。以下、第１実施例と異なる部分を中心として説明する。尿に含まれている糖、蛋白、潜血等と反応して変色することにより、糖、蛋白、潜血等の異常の有無を簡易的に判定する試薬成分、試薬成分を担持した試験片が、従来、提供されている。そこで本実施例によれば、図１０に示すように、当該試薬成分を含む収容する収容部２００（試薬収容手段）と、収容部２００と洗浄口４５とを繋ぐ通路２０２と、通路２０２に設けられた開閉バルブ２０４とを基部１０に装備しており、更に、開閉バルブ２０６を開閉する試薬供給スイッチ２０８を基部１０の操作パネルに装備している。目標部３が退避箇所Ｍ２に退避している状態において、つまり、洗浄口４５に目標部３が対面している状態において、放尿の際に、試薬供給スイッチ２０８を操作して開閉バルブ２０４を開放し、収容部２００内の試薬成分を洗浄口４５から目標部３に供給することができる。放尿の際に目標部３に尿を当たれば、目標部３に供給された試薬成分と尿とが接触するため、尿成分に異常があれば、試薬成分は尿と反応して変色するため、尿を簡易的に検査することができる。保持部材２が退避位置Ｐ２に退避して目標部３が退避箇所Ｍ２に退避する際に、目標部３に付着した洗浄成分は、洗浄口４５から目標部３に向けて吐出される水により洗浄される。従って洗浄口４５は、基部１０に設けられ目標部３に付着した洗浄成分を洗浄して除去する試薬除去手段として機能できる。試薬供給スイッチ２０８及び開閉バルブ２０４は、基部１０に設けられており、目標部３に試薬成分を供給する試薬供給手段として機能できる。
【００４８】
（他の実施例）
上記した第１実施例によれば、尿が目標部３に当たったとき、音響発生部７のスピーカ駆動回路７１を駆動させ、スピーカ７０を鳴らして音響を発生させることにしているが、これに限らず、便座１１の開放動作と、音響発生部７による音響発生とを連動させても良い。この場合、便座１１が開放されて便座スイッチ１３が便座１１の開放を検知したとき、あるいは、便座スイッチ１３が便座１１の開放を検知して所定時間（便座１１の開放から放尿開始までの時間を考慮したもの）経過したとき、音響発生部７のスピーカ駆動回路７１を駆動させ、スピーカ７０を鳴らして音響を発生させると共に、便座１１の閉鎖に伴い音響の発生を停止させることにしても良い。この場合、目標部３に取り付けるセンサ７４を廃止することができる。即ち、保持部材２が使用位置Ｐ１に設定される条件（便座１１を開放させること）が満たされたとき、放尿されると推定できるため、放尿音を低減または解消すべく、音響発生部７が音響を発生させることにする。また上記した主筒４０に供給する水を溜めるタンク５０は、人体の局部を洗浄する洗浄ノズル１８用の洗浄水を貯留する温水タンクと共用化しても良い。便座１１をもつ便器９に適用しているが、便座１１をもたない便器に適用しても良い。その他、本発明は上記し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。
【００４９】
【発明の効果】
各様相の本発明によれば、使用者（主として男性）が放尿するとき、便器内の目標部は使用者の放尿の目標となる。このため便器内に放尿される確率が増加し、尿の飛散が抑制され、床面などの便器周辺の汚れを抑えることができる。

When the toilet seat 11 is pivoted upward (in the direction of the arrow U1) and opened, a projection 15 as an operation portion provided on the pivotal support portion 14 of the toilet seat 11 presses the switch portion 13k of the toilet seat switch 13 to turn it on. Therefore, the opening of the toilet seat 11 is detected. When the toilet seat 11 in the open state rotates downward (in the direction of the arrow U2) and is closed, the protrusion 15 provided on the pivot 14 of the toilet seat 11 does not press the switch portion 13k of the toilet seat switch 13, so the toilet seat switch 13 is turned off, and the closing of the toilet seat 11 is detected.
[0023]
[Table 1]

[0024]
Here, Table 1 shows the opened / closed state of the toilet seat 11 and the operational relationship of the toilet seat switch 13, the water stop valve 55, the first valve 61, and the second valve 62. No. in Table 1 As shown in FIG. 1, when the toilet seat 11 is opened, the toilet seat switch 13 is turned on, the water stop valve 55 is turned on, the first valve 61 is turned on, the second valve 62 is turned off, and the timer 76 is turned off. . In Table 1, No. 2, immediately after the toilet seat 11 opened for urine is closed, the toilet seat switch 13 is turned off, the water stop valve 55 is turned on, the first valve 61 is turned off, and the second valve 62 is turned on. The timer 76 is turned on. In Table 1, No. 3, in a normal state where the toilet seat 11 continues to be closed, the toilet seat switch 13 is turned off, the water stop valve 55 is turned off, the first valve 61 is turned off, and the second valve 62 is turned off. Is turned off.
[0025]
Furthermore, explanation is added about use. In the normal state where the toilet seat 11 continues to be closed, No. 1 in Table 1 appears. 3, the toilet seat switch 13 is turned off, the water stop valve 55 is turned off, the first valve 61 is turned off, the second valve 62 is turned off, and the timer 76 is turned off. Therefore, water supply from the faucet 54 to the tank 50 is stopped, and water supply from the first water passage 60 to the water supply port 47 and water supply from the second water passage 60 to the cleaning port 45 are stopped. For this reason, the movable rod portion 21 is urged to the retracted position P2 in the direction of arrow A2 by the urging force of the urging spring 22, and as shown by the phantom line in FIG. Is approaching or in contact with the second stopper portion 44. As a result, as indicated by phantom lines in FIG. 2, the target portion 3 is retracted to the retreat location M <b> 2, and the upper surface of the target portion 3 faces the cleaning port 45. When the target portion 3 is retracted to the retreat location M2, the target portion 3 is covered by the cover portion 40p of the main cylinder 40.
[0026]
The toilet seat device 1 according to the present embodiment has a cleaning nozzle 18 at the base 10 for cleaning a local part (anus or the like) of a human body.
[0027]
FIG. 6 shows a block diagram of the control system. As shown in FIG. 6, the signal of the toilet seat switch 13, the signal of the cleaning switch 77 that operates the cleaning nozzle 18, the signal of the cancel switch 78 described later, and the signal of the acoustic cancel switch 79 described later are input to the control device 100. . The command signal from the control device 100 includes a drive circuit 55w for the water stop valve 55, a drive circuit 61w for the first valve 61, a drive circuit 62w for the second valve 62, a speaker drive circuit 71, a drive circuit 18w for the cleaning nozzle 18, and a timer. 76, the water stop valve 55, the first valve 61, the second valve 62, the speaker 70, the cleaning nozzle 18, and the timer 76 are controlled. Note that the timer 76 may be an internal timer of the microcomputer.
[0028]
Next, a description will be given of when the user (mainly male) urinates in the toilet bowl 9. In this case, the toilet lid 12 and the toilet seat 11 are lifted and opened. An opening / closing mechanism (not shown) lifts and opens the toilet lid 12 and the toilet seat 11 by the user himself or according to a signal detected by the user. When the toilet seat 11 is thus opened, the toilet seat switch 13 detects the opening of the toilet seat 11. Then, the control apparatus 100 is No. of Table 1. As shown in FIG. 1, the water stop valve 55 is turned on, the first valve 61 is turned on, and the second valve 62 is turned off. Thereby, water from the faucet 54 is supplied to the tank 50, and the water in the tank 50 is supplied to the water chamber 41 of the main cylinder 40 through the first water passage 60 b and the water supply port 47.
[0029]
As a result, due to the water pressure in the water chamber 41, the movable rod portion 21 moves forward in the direction of the arrow A1 against the urging force of the urging spring 22 and moves toward the use position P1, and the movable main body 20 moves to the first stopper portion 43. The movable rod portion 21 stops at the position where it hits. In this state, the target unit 3 is set to the target location M1. In this case, as shown in FIG. 1, the target portion 3 protrudes into the toilet bowl 9 and is positioned above the water surface WA of the water stored in the toilet bowl 9. Since the urination target is set in the toilet bowl 9 in this way, the user naturally urinates to hit the target section 3 and the urine is prevented from being scattered outside the toilet bowl 9. This is particularly effective when the user is a child. For this reason, scattering of urine around the toilet 9 such as the floor surface is suppressed, and the cleanliness of the toilet can be improved. In particular, since the target unit 3 includes the buffer unit 32 having a buffering property to suppress urine scattering, urine rebound from the target unit 3 is suppressed, urine scattering around the toilet 9 is suppressed, and the toilet is clean. Can be improved.
[0030]
Even if urine hits the target portion 3, since the water is supplied to the water chamber 41, the movable rod portion 21 of the holding member 2 is prevented from moving backward in the arrow A2 direction. Accordingly, the water chamber 41 to which water is supplied can function as a retraction suppressing unit that suppresses the retraction of the movable rod portion 21 of the holding member 2 when urine hits the target portion 3. Further, as shown in FIG. 2, the movable rod portion 21 of the holding member 2 is supported by a receiving portion 40 t having an inner diameter corresponding to the outer diameter of the movable rod portion 21 in the main cylinder 40, and Since the movable main body 20 is constrained facing the restraint surface 41t of the inner wall surface of the water chamber 41, the swinging of the movable rod portion 21 of the holding member 2 does not occur even when urine hits the target portion 3 in an impact. It is suppressed. Therefore, the receiving portion 40t and the restraining surface 41t can function as restraining means that restrains the swinging of the movable rod portion 21 of the holding member 2 when urine strikes the target portion 3 in an impact.
[0031]
According to the present embodiment, when the urine hits the target unit 3, the impact force is detected by the sensor 74 mounted on the target unit 3. The detection signal of the sensor 74 is input to the control device 100, and the control device 100 drives the speaker drive circuit 71 of the sound generation unit 7 to emit sound from the speaker 70. As sound, music, stream sounds, maxims, advice for urination, animal calls, etc. can be employed. That is, in the area of the memory 102 functioning as a storage unit mounted on the control device 100, as music, a plurality of music (a1, a2...), A plurality of water currents (b1, b2...), A plurality of maxims ( c1, c2...), a plurality of advices (d1, d2...) for the urination operation, and a plurality of animal calls (e1, e2...) are stored. Therefore, the user can select any of music, water current, maxim, advice for urination, and animal cry according to the user's preference by using the selection switch 75 provided on the operation panel of the base 10. . If the sound is an advice for the urination operation, the urination operation according to the advice is advantageous in preventing urine scattering even if the user is an infant.
[0032]
When the urine is hitting the target unit 3 in this way, the sound is emitted from the speaker 70, so that urine can be released while listening to the sound, and the mood is refreshed or distracted. Furthermore, since the unpleasant sound of urine hitting the water in the toilet bowl 9 can be reduced or eliminated by sound, it is possible to urinate without hesitation even in a small room, which is environmentally advantageous.
[0033]
Further, as described above, when the urine is hitting the target unit 3, the sound is emitted from the speaker 70. When the urine is not hitting the target unit 3, the sound is interrupted or the type of the sound is changed. In this case, since it is recognized that urine does not hit the target portion 3, it is possible to contribute to improving the direction of urination for the toilet 9.
[0034]
Further, the toilet seat 11 is closed together with the toilet lid 12 after urination. In this case, an opening / closing mechanism (not shown) opens the toilet lid 12 and the toilet seat 11 by the user himself or in response to a signal that detects the user leaving the toilet. No. in Table 1 As shown in FIG. 2, since the toilet seat 11 that has been opened is closed, the toilet seat switch 13 is turned off, the water stop valve 55 is kept on, the first valve 61 is turned off, and the second valve 62 is turned on. The timer 76 is turned on and the timer operation is started. The timer 76 defines the ON time of the second valve 62, and the ON of the second valve 62 is maintained during the timer setting time.
[0035]
Since the first valve 61 is turned off as the toilet seat 11 is closed in this way, the water in the stop cock 54 is supplied to the tank 50, but the water in the tank 50 is not supplied to the water supply port 47. When the first valve 61 is thus turned off, the drain passage 63 is opened. For this reason, the water in the water chamber 41 is pushed back in the direction of the arrow E1 (see FIG. 2) by the movable main body 20 biased by the biasing spring 22. That is, the urging force of the urging spring 22 overcomes the pressure of the water in the water chamber 41, the water in the water chamber 41 is discharged from the drain through the drain passage 63, and the piston-like movable body is urged by the urging spring 22. 20 and the movable rod portion 21 move in the direction of the arrow A2 to reach the retreat position P2, and the target portion 3 is retreated to the retreat location M2. Thus, when the holding member 2 is retracted to the retracted position P2 and the target portion 3 is retracted to the retracted position M2, the upper surface of the target portion 3 faces the cleaning port 45. At this time, since the water stop valve 55 and the second valve 62 are on, the water of the water stop cock 54 is supplied to the tank 50, and the water of the tank 50 further passes through the second valve 62 and the second water passage 60c. Then, the target unit 3 is cleaned by the water supplied to the cleaning port 45 and then discharged from the cleaning port 45. Thereby, the dirt of the target part 3 is removed. Although urine is mainly applied to the upper surface of the target unit 3, the cleaning port 45 that discharges cleaning water faces the upper surface of the target unit 3, which is advantageous for cleaning the upper surface of the target unit 3.
[0036]
Since the second valve 62 is kept on until the set time of the timer 76 is turned off, the cleaning of the target unit 3 is executed until the set time of the timer 76 is turned off. Therefore, the timer 76 can function as a cleaning time setting means for setting a cleaning time for cleaning the target unit 3. Since the cleaning capability for the target unit 3 is variable, the set time of the timer 76 can be adjusted. When the set time of the timer 76 is turned off, the water stop valve 55 and the second valve 62 are turned off, and the cleaning process of the target unit 3 is finished. In this way, the target unit 3 which is hit by the urine is cleaned by the water discharged from the cleaning port 45 every time the urine is finished and the toilet seat 11 and the toilet lid 12 are closed. It can be maintained hygienically.
[0037]
According to this embodiment, as can be understood from the above description, the water in the tank 50 is supplied to the water supply port 47 to move the holding member 2 to the use position P1 via the first water passage 60b. The water is supplied as cleaning water to the cleaning port 45, which is the target cleaning unit, via the second water passage 60b. For this reason, the water in the tank 50 is commonly used for the purpose of moving the holding member 2 to the use position P1 and the purpose of cleaning the target portion 3 soiled with urine, and the use timing of both uses is basically. Are not the same and are shifted in time, which can contribute to reducing the number of tanks 50 and the tank volume of the tanks 50. According to the present embodiment, when the toilet seat 11 is opened, the holding member 2 automatically advances to the use position P1, and the target portion 3 is set to the target location M1. Therefore, unless the toilet seat 11 is pivoted upward to open the toilet seat 11, the holding member 2 does not advance to the use position P1, and thus the target portion 3 is not projected to the target location M1 in the toilet bowl 9. That is, when the toilet seat 11 is pivoted downward and closed, the target portion 3 is not projected to the target location M1 in the toilet bowl 9. Therefore, when the user's waist rests on the toilet seat 11 that is pivoted downward and closed, and the user defecates, the holding member 2 does not move forward to the use position P1, and the target unit 3 is consequently moved to the toilet bowl 9. The stool is not projected to the target location M1 but is evacuated to the evacuation location M2, so that the stool is prevented from coming into contact with the holding member 2 and the target portion 3, and the stool is contaminated with the stool. Can be prevented.
[0038]
According to the present embodiment, as described above, when the toilet seat 11 is opened, the holding member 2 is automatically advanced in the direction of the arrow A1 by the water pressure in the water chamber 41 and moved to the use position P1. A cancel switch 78 functioning as a canceling means for canceling is provided on the operation panel of the base 10. That is, the cancel switch 78 does not move the holding member 2 to the use position P1 and thus does not move the target unit 3 to the target location M1, assuming that the toilet seat 11 is opened for urination.
[0039]
Therefore, if the cancel switch 78 is operated, the first valve 61 is turned off and water is not supplied to the water chamber 41. Therefore, even if the toilet seat 11 is opened, the holding member 2 does not advance to the use position P1, and the retreat position P2 Is kept evacuated. Therefore, even when the toilet seat 11 is opened, the piston-like movable main body 20 and the movable rod portion 21 are moved in the direction of the arrow A2 by the biasing spring 22 to the retreat position P2, and the target portion 3 is retreated to the retreat location M2. Maintained. Therefore, if the cleaner operates the cancel switch 78 at the time of cleaning the inside of the toilet 9, the target unit 3 does not protrude into the toilet 9, and the target unit 3 can be prevented from interfering with the cleaning of the toilet 9, which is convenient. is there.
[0040]
According to the normal control law of the above-described embodiment, when urine hits the target unit 3 as described above, this is detected by the sensor 74, and the detection signal of the sensor 74 is input to the control device 100, and the control device Reference numeral 100 drives the speaker drive circuit 71 of the sound generation unit 7 to sound sound from the speaker 70. Furthermore, an acoustic cancel switch 79 is provided on the operation panel of the base 10 as acoustic canceling means for canceling sound from the speaker 70. Therefore, when quietness is required, such as at night, the user can operate the sound cancel switch 79 to stop sounding from the speaker 70 as necessary.
[0041]
(Second embodiment)
The second embodiment has basically the same configuration and the same function and effect as the first embodiment. Hereinafter, a description will be given centering on differences from the first embodiment. FIG. 7 shows the control law of this embodiment. According to this embodiment, sound is generated according to the degree to which urine hits the target unit 3. The control device 100 obtains the hit rate at which the urine made by the user hits the central area of the target unit 3, and changes the type of sound according to the hit rate. The accuracy with which the urine hits the central area of the target unit 3 is determined by the magnitude of the impact force detected by the sensor 74 or the impact time detected by the sensor 74. The flowchart (see FIG. 7) for defining this control law is activated when the toilet seat is opened and the toilet seat switch 13 is operated. That is, as shown in FIG. 7, after the initial setting (step S102), the signal of the sensor 74 is read a predetermined number of times (steps S104 and S106). And the control apparatus 100 calculates | requires the hit rate of the urine with respect to the target part 3 (step S108). Therefore, step S108 can function as a calculation means for calculating the urine hit rate for the target unit 3.
[0042]
When the hit rate is relatively low (including when it is out of the target unit 3), the control device 100 outputs a signal for generating the first sound to the speaker drive circuit 71 (step S110, step S110). S112). When the accuracy is relatively medium, a signal for generating the second sound is output to the speaker drive circuit 71 (steps S114 and S116). When the hit rate is relatively high, a signal for generating the third sound is output to the speaker drive circuit 71 (steps S118 and S120). When the hit rate detected by the sensor 74 is extremely high, a signal for generating the fourth sound is output to the speaker drive circuit 71 (step S122). In order to prevent an excessive change in sound, the process waits for a predetermined time in step S124. If the toilet seat 11 is not closed, there is a high possibility that urination is continued, and the process returns to step S104. If the toilet seat 11 is closed, urination has been completed, so the control device 100 outputs an acoustic stop signal (step S126, step S128), and ends the control. Steps S126 and S128 can function as sound stopping means for stopping sound. Even if the toilet seat 11 continues to be opened, if a predetermined time elapses, it is estimated that the user has forgotten to close the toilet seat 11, so an acoustic stop signal is output (steps S130 and S128), and control is performed. finish.
[0043]
As the first to fourth sounds, music, water currents, maxims, advice for urination, animal calls, etc. can be adopted, and the level of accuracy is clearly indicated or implied so that the level of accuracy can be identified. Sound can be adopted. Therefore, the first sound is sound that clearly or implies that the hit rate is low. The second sound is a sound that clearly or implies that the hit rate is medium. The third sound is a sound that clearly or implies that the hit rate is high. The fourth sound is a sound that clearly or implies that the hit rate is extremely high.
[0044]
Also in the present embodiment, sound is generated when urine hits the target portion 3 and urination can be performed while listening to the sound, so that the mood is refreshed or distracted. Furthermore, since sound is generated according to the degree of urine hitting the target unit 3 (hit rate), the mood becomes even more refreshing or distracting, and the urine is attempted to hit the target unit 3. In addition to being able to urinate while having fun, the scattering of urine around the toilet 9 can be further suppressed, and the cleanliness of the toilet can be further improved.
