Description

【０００１】
【発明の属する技術分野】
本発明は、用便後の人体局部の洗浄を洗浄水で行うトイレ装置に関するものである。
【０００２】
【従来の技術】
従来例の技術による、トイレ装置（ブロック図）を図５に示す。図５において洗浄部１は人体局部に洗浄水を放出する。タンク２内には洗浄水が貯えられている。ヒータ部３はタンク２内に内蔵されており、タンク２内の洗浄水を加熱する。センサー部４はタンク２内に内蔵されており、タンク２内の洗浄水の温度を検出する。第１洗浄水温設定部５は例えばボリュームで構成されており、ボリュームを回すことによって使用者が好みの洗浄水温を設定できるようになっている。第１洗浄水温設定部５の外観図を図６に示す。図６において湯温の設定はつまみ６を設定範囲７に合わせて行うようになっている。ヒータ制御部８はセンサー部４で検出した温度と目標温度を比較し、目標温度の方が高ければヒータ部３をオン、検出温度の方が高ければヒータ部３をオフすることにより、タンク２内の洗浄水の温度を制御する。ここで第１洗浄水温設定部５で設定された温度を目標温度とすると、タンク２内の洗浄水の熱容量により実際の洗浄水温は設定温度を超える、いわゆるオーバーシュートがおこる。このオーバーシュートを防止するため従来は、特公昭５−１３２１５号公報に記載されているような方法が採られていた。第２洗浄水温設定部９は第１洗浄水温設定部５よりある一定温度低い温度を設定する。タイマ部１０はセンサー部４での検出温度が第２洗浄水温設定部９で設定した温度より低ければ計時を初期化し、検出温度が第２洗浄水温設定部９で設定した温度より高くなったときからある一定時間計時を行う。目標温度制御部Ｃ１１はタイマ部１０が計時を終了するまでは第２洗浄水温設定部９で設定された温度を目標温度とし、タイマ部１０が計時を終了してからは第１洗浄水温設定部５で設定された温度を目標温度とする。つまり洗浄水の温度が一旦下がれば、使用者が設定した温度よりある一定温度低い設定温度に到達するまでヒータ部３をオンし、その後その温度で一定時間制御した後、使用者が設定した設定温度でヒータ部３を制御することにより、短時間で洗浄水を沸き上げ、しかもオーバーシュートを抑えようとするものである。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記構成では第２洗浄水温設定部９での設定温度から第１洗浄水温設定部５での設定温度に急に変更しているため、目標温度の方がセンサー部４での検出温度よりもかなり高くなってしまい、これがオーバーシュートの原因となる。従来例での沸き上げ時の検出温度と目標温度、及びヒータ部３のＯＮ／ＯＦＦの状況を図７に示す。設定温度が切り替わってから検出温度が目標温度に到達するまでヒータ部３がＯＮし続けるため、ヒータ部３がＯＦＦしてからオーバーシュートが生じている。またさらにタンク２を高容量化したり、沸き上げ時間を短くしたりするためにヒータ部２は高ワットのものとなり、この事は、オーバーシュートが大きくなることを意味している。則ち、沸き上げ時間を短縮するために高ワットのヒータを用いれば人体局部に洗浄水が放出された時、単に熱く感じるのみならずやけどの危険も生じることとなる。
【０００４】
【課題を解決するための手段】
本発明は上記課題を解決するために、センサー部での検出温度が、使用者が設定した設定温度よりある一定温度低い設定温度に到達すると徐々に目標温度を上げていき、一定時間経過後に、使用者が設定した設定温度を目標温度とするものである。
【０００５】
上記発明によれば、センサー部での検出温度が、使用者が設定した設定温度よりある一定温度低い設定温度に到達してから徐々に目標温度を上げることにより、目標温度の方がセンサー部での検出温度よりかなり高くなることを抑えることができ、短時間で洗浄水を沸き上げ、しかも少ないオーバーシュートで使用者の設定した設定温度で洗浄水を制御することができ、設定温度より熱いという不快感及びやけどの危険性を防ぐことができる。
【０００６】
【発明の実施の形態】
本発明は、人体局部に洗浄水を放出する洗浄部と、前記洗浄水を貯えるタンクと、前記タンク内の洗浄水を加熱するヒータ部と、前記タンク内の洗浄水温を検出するセンサー部と、使用者が好みの洗浄水温を設定する第１洗浄水温設定部と、前記第１洗浄水温設定部により設定する温度より低い温度を設定する第２洗浄水温設定部と、前記第１洗浄水温設定部及び前記第２洗浄水温設定部からの信号をもとに実際の目標温度を作成する目標温度制御部Ａと、前記センサー部からの信号及び前記目標温度制御部Ａからの信号を比較し、前記ヒータ部の通電を制御しするヒータ制御部と、前記センサー部で検出した温度が前記第２洗浄水温設定部で設定した温度より低くなったときに計時を初期化し、前記センサー部で検出した温度が前記第２洗浄水温設定部で設定した温度より高くなったときからある一定時間計時を行うタイマ部とからなり、前記目標温度制御部Ａは前記タイマ部が計時を開始するまでは前記第２洗浄水温設定部で設定された温度を目標温度とし、前記タイマ部が計時を終了してからは前記第１洗浄水温設定部で設定された温度を目標温度とし、前記タイマ部が計時を行っている間は前記第２洗浄水温設定部で設定された温度から前記第１洗浄水温設定部で設定された温度まで前記タイマ部が計時する一定時間の間にタイマ部の計時値に応じて目標温度を作成するものである。
【０００７】
そして、センサー部での検出温度が、第２洗浄水温設定部で設定した設定温度に到達してから、徐々に目標温度を変更していき、目標温度の方がセンサー部での検出温度よりかなり高くなることを抑えることができ、短時間で洗浄水を沸き上げ、しかも少ないオーバーシュートで洗浄水の温度を第１洗浄水温設定部で制御することができ、設定温度よりも熱いという不快感及びやけどの危険性を防ぐことができる。
【０００８】
また、人体局部に洗浄水を放出する洗浄部と、前記洗浄水を貯えるタンクと、前記タンク内の洗浄水を加熱するヒータ部と、前記タンク内の洗浄水温を検出するセンサー部と、使用者が好みの洗浄水温を設定する第１洗浄水温設定部と、前記第１洗浄水温設定部により設定する温度より低い温度を設定する第２洗浄水温設定部と、前記第１洗浄水温設定部及び前記第２洗浄水温設定部からの信号をもとに実際の目標温度を作成する目標温度制御部Ｂと、前記センサー部からの信号及び前記目標温度制御部Ｂからの信号を比較し前記ヒータ部の通電を制御するヒータ制御部と、前記センサー部で検出した温度が前記第２洗浄水温設定部で設定した温度より低くなったときに計時を初期化し、前記センサー部で検出した温度が前記第２洗浄水温設定部で設定した温度より高くなったときからある一定時間計時を行うタイマ部とからなり、前記目標温度制御部Ｂは前記タイマ部が計時を開始するまでは前記第２洗浄水温設定部で設定された温度を目標温度とし、前記タイマ部が計時を終了してからは前記第１洗浄水温設定部で設定された温度を目標温度とし、前記タイマ部が計時を行っている間は前記第２洗浄水温設定部で設定された温度から前記第１洗浄水温設定部で設定された温度まで単位時間あたりの温度の変化量が一定になるように目標温度を作成するものである。
【０００９】
そして、センサー部での検出温度が、第２洗浄水温設定部で設定した設定温度に到達してから、第１洗浄水温設定部で設定した設定温度まで直線的に目標温度を変更していき、簡単な制御で目標温度の方がセンサー部での検出温度よりかなり高くなることを抑えることができ、短時間で洗浄水を沸き上げ、しかも少ないオーバーシュートで洗浄水の温度を第１洗浄水温設定部で制御することができ、設定温度よりも熱いという不快感及びやけどの危険性を防ぐことができる。
【００１０】
（実施例１）
以下、本発明の技術を用いたトイレ装置の実施例１を図面を用いて説明する。図１は本発明のトイレ装置の実施例１を示すブロック図で従来例の図５と同一部分には同一符号を付して詳細な説明を省略している。図１において目標温度制御部Ａ１２はタイマ部１０が計時を開始するまでは第２洗浄水温設定部９で設定された温度を目標温度とし、タイマ部１０が計時を終了してからは第１洗浄水温設定部５で設定された温度を目標温度とし、タイマ部１０が計時を行っている間はタイマの値に応じて目標温度を制御する。
【００１１】
本発明の実施例１について、図２を用いて説明する。図２は時間的経緯を表したタイミングチャートである。図２において沸き上げ当初は、センサー部４での検出温度が第２洗浄水温設定部９での設定温度より低くなっているので、ヒータ部３がＯＮされる。この間はタイマ部１０は計時されず、初期値を保ったままである。センサー部４での検出温度が第２洗浄水温設定部９での設定温度を超えるとヒータ部３がＯＦＦし、タイマ部１０が計時を開始する。そしてタイマ部１０の値をもとに目標温度が制御される。図２では徐々に時間あたりの変化量が小さくなるようにし、第１洗浄水設定部で設定された付近の温度変化を少なくし、目標温度を設定したが、タンク２の形状や環境の違いによって目標温度の制御の方法は様々に最適化される。センサー部４での検出温度が目標温度制御部Ａ１２で制御された目標温度より低くなるとヒータ部３がＯＮし、検出温度が目標温度を越えるとヒータ部３がＯＦＦする。このことを繰り返しながら徐々に目標温度を第１洗浄水温設定部５での設定温度に近づけていき、タイマ部１０が計時を終了した段階で第１洗浄水温設定部５で設定された設定温度を目標温度とする。この構成により、少ないオーバーシュートでタンク２内の洗浄水温を使用者が設定した設定温度まで短時間で沸き上げ、さらにその温度で制御することのできるトイレ装置を実現することができる。

本発明の技術を用いたトイレ装置の実施例２を図面を用いて説明する。図３は本発明のトイレ装置の実施例２を示すブロック図で従来例の図５と同一部分には同一符号を付して詳細な説明を省略している。図３において目標温度制御部Ｂ１３はタイマ部１０が計時を開始するまでは第２洗浄水温設定部９で設定された温度を目標温度とし、タイマ部１０が計時を終了してからは第１洗浄水温設定部５で設定された温度を目標温度とし、タイマ部１０が計時を行っている間は第２洗浄水温設定部９で設定された温度から第１洗浄水温設定部５で設定された温度まで単位時間あたりの変化量が一定になるように目標温度を制御する。
【００１３】
本発明の実施例２について、図４を用いて説明する。図４は時間的経緯を表したタイミングチャートである。図４において沸き上げ当初は、センサー部４での検出温度が第２洗浄水温設定部９での設定温度より低くなっているので、ヒータ部３がＯＮされる。この間はタイマ部１０は計時されず、初期値を保ったままである。センサー部４での検出温度が第２洗浄水温設定部９での設定温度を超えるとヒータ部３がＯＦＦし、タイマ部１０が計時を開始する。そしてタイマ部１０の値をもとに、第２洗浄水温設定部９での設定温度から第１洗浄水温設定部５での設定温度まで直線的に目標温度が制御される。センサー部４での検出温度が目標温度制御部Ｂ１３で制御された目標温度より低くなるとヒータ部３がＯＮし、検出温度が目標温度を越えるとヒータ部３がＯＦＦする。このことを繰り返しながら徐々に目標温度を第１洗浄水温設定部５での設定温度に近づけていき、タイマ部１０が計時を終了した段階で第１洗浄水温設定部５で設定された設定温度を目標温度とする。この構成により少ないオーバーシュートでタンク２内の洗浄水温を使用者が設定した設定温度まで短時間で沸き上げ、さらにその温度で制御することのできるトイレ装置を簡単な制御で実現することができる。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a toilet apparatus that cleans a human body part after stool using flush water.
[0002]
[Prior art]
FIG. 5 shows a toilet apparatus (block diagram) according to a conventional technique. In FIG. 5, a washing unit 1 discharges washing water to a human body part. Wash water is stored in the tank 2. The heater unit 3 is built in the tank 2 and heats the cleaning water in the tank 2. The sensor unit 4 is built in the tank 2 and detects the temperature of the washing water in the tank 2. The first cleaning water temperature setting unit 5 is constituted by, for example, a volume, and a user can set a desired cleaning water temperature by turning the volume. FIG. 6 shows an external view of the first cleaning water temperature setting unit 5. In FIG. 6, the setting of the hot water temperature is performed by adjusting the knob 6 to the setting range 7. The heater control unit 8 compares the temperature detected by the sensor unit 4 with the target temperature. If the target temperature is higher, the heater unit 3 is turned on, and if the detected temperature is higher, the heater unit 3 is turned off. To control the temperature of the washing water inside. Here, when the temperature set by the first washing water temperature setting unit 5 is set as the target temperature, the so-called overshoot occurs in which the actual washing water temperature exceeds the set temperature due to the heat capacity of the washing water in the tank 2. In order to prevent this overshoot, a method as described in JP-B-5-13215 has conventionally been adopted. The second cleaning water temperature setting unit 9 sets a temperature lower than the first cleaning water temperature setting unit 5 by a certain temperature. The timer section 10 initializes the time measurement if the temperature detected by the sensor section 4 is lower than the temperature set by the second washing water temperature setting section 9, and when the detected temperature becomes higher than the temperature set by the second washing water temperature setting section 9. From a certain time. The target temperature control unit C11 sets the temperature set by the second cleaning water temperature setting unit 9 as the target temperature until the timer unit 10 finishes measuring the time, and sets the first cleaning water temperature setting unit after the timer unit 10 finishes measuring the time. The temperature set in 5 is set as the target temperature. That is, once the temperature of the washing water drops, the heater unit 3 is turned on until the set temperature reaches a certain temperature lower than the temperature set by the user, and after that the temperature is controlled for a certain time, and then the setting set by the user is performed. By controlling the heater section 3 with the temperature, the cleaning water is boiled in a short time and the overshoot is suppressed.
[0003]
[Problems to be solved by the invention]
However, in the above configuration, since the temperature set by the second cleaning water temperature setting unit 9 is suddenly changed from the temperature set by the first cleaning water temperature setting unit 5, the target temperature is higher than the temperature detected by the sensor unit 4. Is also quite high, which causes overshoot. FIG. 7 shows the detected temperature and target temperature at the time of boiling in the conventional example, and the ON / OFF state of the heater unit 3. Since the heater unit 3 is kept on until the detected temperature reaches the target temperature after the set temperature is switched, overshoot occurs after the heater unit 3 is turned off. Further, in order to increase the capacity of the tank 2 or to shorten the boiling time, the heater section 2 has a high wattage, which means that the overshoot increases. In other words, if a high-wattage heater is used to shorten the boiling time, when the washing water is discharged to a local part of the human body, it will not only feel hot but also cause a risk of burns.
[0004]
[Means for Solving the Problems]
The present invention, in order to solve the above problem, the temperature detected by the sensor unit, gradually reaches the target temperature when the set temperature set by the user reaches a certain temperature lower than a certain temperature, after a certain time, The set temperature set by the user is used as the target temperature.
[0005]
According to the invention described above, the target temperature is increased by the sensor unit by gradually increasing the target temperature after the temperature detected by the sensor unit reaches the set temperature lower by a certain temperature than the set temperature set by the user. Can be prevented from becoming much higher than the detected temperature, the washing water can be boiled in a short time, and the washing water can be controlled at the set temperature set by the user with a small amount of overshoot. The risk of discomfort and burns can be prevented.
[0006]

[0007]
