Description

【０００１】
【発明の属する技術分野】
本発明は、便器の使用者をセンサで検知し、自動的に便蓋及び便座の開閉を行うトイレ装置に関する。
【０００２】
【従来の技術】
例えば、特開２００１−１９０４５０公報には、一つの検知センサで便座及び便蓋が閉じた状態にあるときに、使用者を検知して自動的に便蓋を開けて、その用途に応じて便座を開き、用便完了後はこれらの便座及び便蓋を閉じる技術が開示されている。
【０００３】
【発明が解決しようとする課題】
しかしながら、前記公報記載の技術において、検知センサとして赤外線センサを使用し、便蓋の開閉によって検知センサの投受光が遮られることがあるので、検知センサ自体に角度調整手段を設けてその検知角度を変えていた。このため、その構造が複雑となって、組み立てやメンテナンスに手間がかかるという問題もあった。
一方、便器の前に使用者が立った状態を検知する人体検知センサと、使用者が便座に座ったことを検知する着座検知センサとを用いて、便蓋及び便座の開閉を行うことが提案されているが、使用者が予め設定された通りの動作を行う必要があった。
本発明はかかる事情に鑑みてなされたもので、動く部分がなく、使用者の状況に応じてより確実な動作を行う便蓋及び便座の自動開閉機構付きトイレ装置を提供することを目的とする。
【０００４】
【課題を解決するための手段】
前記目的に沿う第１の発明に係る便蓋及び便座の自動開閉機構付きトイレ装置は、便器の前に使用者が立っている状態を検知する人体検知センサと、便座の上に使用者が座ったことを検知する着座検知センサとを備え、前記人体検知センサと前記着座検知センサの出力によって、便蓋及び前記便座の自動開閉を行うトイレ装置であって、前記人体検知センサを、前記便蓋を閉じた状態で使用者を検知する第１の人体検知センサと、前記便座を閉じた状態で、且つ、前記便蓋を開けた状態で、使用者を検知する第２の人体検知センサに分けて構成されている。
【０００５】
また、第２の発明に係る便蓋及び便座の自動開閉機構付きトイレ装置は、第１の発明に係る便蓋及び便座の自動開閉機構付きトイレ装置において、前記第１の人体検知センサは、前記便器の後ろ側上部に設けられた機能部収納ケースの手前側にある軸受ハウジング部に前記便蓋を閉めた状態で露出して設けられ、前記第２の人体検知センサ及び前記着座検知センサは、前記機能部収納ケースの手前側で、閉じた状態の前記便蓋が被さる部分にそれぞれ設けられ、前記便蓋が開時に露出している。ここで、この自動開閉機構付きトイレ装置において、前記第２の人体検知センサ及び前記着座検知センサは、前記機能部収納ケースの両側にそれぞれ設けられているのが好ましい。
【０００６】
そして、第３の発明に係る便蓋及び便座の自動開閉機構付きトイレ装置は、第１、第２の発明に係る便蓋及び便座の自動開閉機構付きトイレ装置において、前記人体検知センサと前記着座検知センサの投受光窓は、前記便器の色彩と同一又は近似の色彩で透光性を有する物質が使用されている。
これによって、外側から見た場合、人体検知センサや着座検知センサが分からないと共に、これらの投受光窓は便器の色彩と同一又は近似しているので、デザイン性に優れる。
【０００７】
【発明の実施の形態】
続いて、添付した図面を参照しつつ、本発明を具体化した実施の形態につき説明し、本発明の理解に供する。
図１は本発明の一実施の形態に係る便蓋及び便座の自動開閉機構付きトイレ装置のブロック図、図２〜図４は同トイレ装置の説明図、図５、図６は同トイレ装置の動作状態を示す説明図である。
【０００８】
図１〜図４に示すように、本発明の一実施の形態に係る便蓋及び便座の自動開閉機構付きトイレ装置１０は、陶器製の便器１１の後側上部に機能部収納ケース１２が設けられ、この機能部収納ケース１２の前側の一方には第１の人体検知センサ１３が設けられている。機能部収納ケース１２の手前側には便蓋１４及び便座１５の軸受ハウジング部１６が設けられ、便蓋１４を開けた場合に、露出する軸受ハウジング部１６の一方側には着座検知センサ１７が、他方側には第２の人体検知センサ１８が設けられている。
第１、第２の人体検知センサ１３、１８及び着座検知センサ１７は反射型の赤外線センサからなって、それぞれ設定された距離内にある物体（例えば、使用者）を検知できる。
【０００９】
第１の人体検知センサ１３は便蓋１４を閉じた場合に露出して使用され、図２に示すように、便器１１の前に立っている使用者を検知できるようにその位置及びセンサの検知距離が設定されている。第１の人体検知センサ１３は、便蓋１４を開けた場合、その検知光が便蓋１４によって遮られて、便器１１の正面側にいる人を検知できない。
第２の人体検知センサ１８は、便蓋１４を開けたときに露出し、便器１１の正面側に立っている人を検知するようになっている。また、着座検知センサ１７は便蓋１４を開けた状態で人体の検知を行い、検知距離を短く設定し、便座１５の上に座った使用者を検知している。そして、着座検知センサ１７によっては、便器１１とは隙間をあけて正面側にいる人は検知しないようになっている。
従って、第２の人体検知センサ１８及び着座検知センサ１７は便蓋１４を閉じた場合、外部から見えないようになっている。
また、第１、第２の人体検知センサ１３、１８及び着座検知センサ１７の投受光窓には、便器１１の色彩と異なる色彩（黒色又は茶色）の透光性を有する物質を使用することも可能であるが、見た目に目立つので、便器１１の色彩と同一又は近似の色彩（例えば、アイボリ、ホワイト、パール等）に着色されてかつ透光性を有する物質を使用するのが好ましい。
【００１０】
機能部収納ケース１２内には、このトイレ装置１０の全体の制御を行う機器が設けられ、更にはこれらの機器の全体の制御を行う制御装置１９が設けられている。図１に、特に、便蓋１４と便座１５の動作に関係ある部分の機器のブロック図を示すが、制御装置１９にはＣＰＵ２０、これに接続されるＲＯＭ２１及びＲＡＭ２２を備え、インターフェース２３を介して、第１、第２の人体検知センサ１３、１８、着座検知センサ１７に接続され、更に、便蓋１４の開閉動作を行う便蓋開閉モータ２４、便座１５の開閉動作を行う便座開閉モータ２５、使用後の便器１１の清掃を行う場合にオンとなる洗浄水開閉弁２６及び脱臭ファン２７に接続されている。また、便蓋１４が開いた位置を検知する便蓋開のリミットスイッチ１４ａ及び便座１４を開けるための手動の便座開スイッチ１４ｂが設けられている。なお、この制御装置１９には、局部の洗浄を行う装置や便座１５の暖房を行う装置等が設けられているが、従来技術（例えば、特開２００１−１３２０４７）と同じであるし、本発明とは特に密接な関係を有しないので、その他の機器として表し、詳しい説明を省略する。
【００１１】
制御装置１９のＲＯＭ２１には、トイレ装置１０の全体の制御を行うプログラムが記載されており、その中に、第１、第２の人体検知センサ１３、１８及び着座検知センサ１７の検知によって、便蓋１４及び便座１５の開閉動作、並びに便器洗浄を行うための洗浄水開閉弁２６及び脱臭ファン２７の動作も記載されているので、以下、図２〜図６を参照しながらその動作について説明する。
まず、図５に示す便座１５を使用してこのトイレ装置１０を使用する場合について説明する。
最初の状態では、便座１５、便蓋１４共に閉じており、この状態で使用者が便器１１の正面側に立つと、図２（Ａ、Ｂ）に示すように使用者を第１の人体検知センサ１３が検知して、便蓋開閉モータ２４が駆動され、便蓋１４が開く。便蓋１４の開の完了を、便蓋開リミットスイッチ１４ａによって検知して、着座検知センサ１７及び第２の人体検知センサ１８を作動させる。なお、第１の人体検知センサ１３は便蓋１４が開いた後は有効に作動しないので止めていても良いのであるが、この実施の形態では常時働かせてその出力をキャンセルするようにしている。着座検知センサ１７及び第２の人体検知センサ１８は便蓋１４が開いた期間中のみ作動させるようにしている。この状態では、図３（Ａ、Ｂ）に示すように、使用者を第２の人体検知センサ１８が検知している。
【００１２】
使用者が便座１５の上に座れば、着座検知センサ１７及び第２の人体検知センサ１８が作動することになるので、脱臭ファン２７を作動させる。使用者が用便を済ませて便座１５から離れると、着座検知センサ１７がオフ状態となるので、脱臭ファン２７の回転数を上げる指示を与えてパワー脱臭する。使用者が便器１１の正面側から離れると、第２の人体検知センサ１８がオフの状態となるので、第１のタイマー（例えば、Ｔ１＝２〜２０秒）をカウントさせ、カウント終了後洗浄水開閉弁２６に信号を送って開き、便器１１の洗浄を行うと共に、パワー脱臭を停止する。また、第２の人体検知センサ１８がオフの状態になったことから、第２のタイマー（例えば、Ｔ２＝２０〜６０秒）をカウントさせ、このタイマーのカウント後、便蓋開閉モータ２４に信号を与えて、便蓋１４を閉じると共に第２の人体検知センサ１８及び着座検知センサ１７の作動を止める。
以上の工程によって、便座１５を用いる男子女子の用便が行える。なお、第１、第２のタイマーは別に設けてもよいが、特別にタイマーを設けないで、プログラムに組み込むこともできる。
【００１３】
次に、図６を参照しながら、男子が小用をする場合について説明する。
使用者が便器１１の正面側に立ったことを、第１の人体検知センサ１３によって検知し、便蓋１４を開き、便蓋１４が開いたことを検知して、第２の人体検知センサ１８及び着座検知センサ１７を作動させる（ここまでは、便座１４を使用する用便方法と同じ）。
この状態で、使用者が便器１１の近傍に設けられている便座開スイッチ１４ｂをオンにすると、便座開閉モータ２５が駆動して便座１５が開く。図４に示すように、便座１５が開くと使用者は小用を行うことができ、完了すると使用者は便器１１の前から去るので、これを第２の人体検知センサ１８が検知し、第１のタイマーをカウントして便器１１の洗浄を行い、第２のタイマーをカウントして便座１５及び便蓋１４を閉じ、第２の人体検知センサ１８及び着座検知センサ１７の作動状態を停止する。
なお、男子小用の場合には、便座１５上には着座しないので、着座検知センサ１７は人体を検知しないことになる。
【００１４】
前記実施の形態においては、第１、第２のタイマーのカウント時間（Ｔ１、Ｔ２）を具体的な数字を用いて説明したが、本発明はこれらの数字に限定されるものではない。また、第１、第２の人体検知センサや着座検知センサの取付け位置は前記実施の形態に限定されず、本発明の要旨を変更しない範囲での取付け位置の変更は可能である。
なお、便蓋１４、便座１５や機能部収納ケース１２を成形する際に、原料中にメタルやパールの原料（具体的にはアルミ粉や雲母粉）を混入して成形して、表面に模様を出し、その上にクリア塗装（透明塗装）を行うようにすることもでき、これによって、表面にクリア感を与えることができる。
【００１５】
【発明の効果】
請求項１〜４記載の便蓋及び便座の自動開閉機構付きトイレ装置は、以上の説明からも明らかなように、人体検知センサを、便蓋を閉じた状態で立った状態の使用者を検知する第１の人体検知センサと、便蓋を開けた状態で立った状態の使用者を検知する第２の人体検知センサに分けているので、その動作が確実になり、しかも、可動部がないので、長期の寿命を有することとなった。
更には、便蓋及び便座のヒンジ部分を切り欠くことなく、人体検知センサ及び着座検知センサを取付けることができるので、便座を広く使用できる。
特に、請求項３記載の便蓋及び便座の自動開閉機構付きトイレ装置において、第２の人体検知センサ及び着座検知センサは、機能部収納ケースの両側にそれぞれ設けられているので、相互に干渉を起こすことなく、確実な動作が期待できる。
そして、請求項４記載の便蓋及び便座の自動開閉機構付きトイレ装置においては、人体検知センサと着座検知センサの投受光窓が便器の色彩にマッチし、デザイン性に優れる。

When the user finishes the toilet and leaves the toilet seat 15, the seating detection sensor 17 is turned off, so that an instruction to increase the rotational speed of the deodorizing fan 27 is given to deodorize the power. When the user moves away from the front side of the toilet 11, the second human body detection sensor 18 is turned off, so that the first timer (for example, T1 = 2 to 20 seconds) is counted, and the wash water after the count ends. A signal is sent to the on-off valve 26 to open it, and the toilet 11 is cleaned and power deodorization is stopped. Further, since the second human body detection sensor 18 is turned off, a second timer (for example, T2 = 20 to 60 seconds) is counted, and after this timer is counted, a signal is sent to the toilet lid opening / closing motor 24. To close the toilet lid 14 and stop the operation of the second human body detection sensor 18 and the seating detection sensor 17.
By the above process, boys 'and girls' stool using the toilet seat 15 can be performed. Although the first and second timers may be provided separately, they can be incorporated in the program without any special timer.
[0013]
Next, with reference to FIG. 6, a case where a boy makes a small use will be described.
It is detected by the first human body detection sensor 13 that the user has stood on the front side of the toilet 11, the toilet lid 14 is opened, the opening of the toilet lid 14 is detected, and the second human body detection sensor 18. And the seating detection sensor 17 is actuated (the process up to here is the same as the method of using the toilet seat 14).
In this state, when the user turns on the toilet seat opening switch 14b provided in the vicinity of the toilet 11, the toilet seat opening / closing motor 25 is driven to open the toilet seat 15. As shown in FIG. 4, when the toilet seat 15 is opened, the user can make a small use. When the toilet seat 15 is completed, the user leaves the front of the toilet 11, and this is detected by the second human body detection sensor 18. The first timer is counted to wash the toilet 11, the second timer is counted to close the toilet seat 15 and the toilet lid 14, and the operation states of the second human body detection sensor 18 and the seating detection sensor 17 are stopped.
In the case of small boys, the seat detection sensor 17 does not detect a human body because it is not seated on the toilet seat 15.
[0014]
In the above embodiment, the count times (T1, T2) of the first and second timers have been described using specific numbers, but the present invention is not limited to these numbers. Further, the mounting positions of the first and second human body detection sensors and the seating detection sensor are not limited to the above-described embodiments, and the mounting positions can be changed without changing the gist of the present invention.
