【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、洗浄水がある一定以上の高温になった場合には、洗浄機能を停止とするものがある（例えば、特許文献１参照。）。
【０００３】

【０００４】
これは、衛生洗浄装置の故障時など、高温の水が人体へ直接かかり、火傷等の危害が加わることを防止するためである。その一方で、以下のような不都合を生じていた
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、寒冷地や冬場での配管の凍結防止のため、配管をテープヒータなどで加熱している。このテープヒータの温度制御がラフであると、温水洗浄装置に接続される配管内の水が一時的に高温になり、衛生洗浄装置の洗浄機能を使用中に、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、衛生洗浄装置へ接続される配管内の水が人体に影響を与える程の高温になるのは配管内の一部分であることが多く、この部分的な高温の水を排水すれば再度衛生洗浄装置が使用可能であるにもかかわらず、洗浄機能が使用不可状態となってしまうため、使用者が衛生洗浄装置の電源をリセットするなどしても、洗浄水貯留手段内に高温の水が留まっているため制御手段が洗浄動作を停止したままであり、洗浄水貯留手段内の水を抜くか、洗浄水貯留手段内の水が自然に放熱して、温度が下がるまで待つ必要があるため、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、衛生洗浄装置に接続される配管内の一部の水が高温であっても、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、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、人体局部へ向けて洗浄水を噴出する洗浄用ノズルと、前記洗浄用ノズルを駆動するノズル駆動手段と、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、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、所定時間を経過するまで給水を継続して洗浄水が人体に当たらない状態で前記洗浄水を系外に吐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内に流入しても、洗浄水が人体に噴出しない洗浄ノズルの位置で一定時間給水し続けるため、洗浄水温度検出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、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、人体局部へ向けて洗浄水を噴出する洗浄用ノズルと、前記洗浄用ノズルを駆動するノズル駆動手段と、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、前記洗浄水温度検知手段による検知温度が第１の設定値以上の高温である場合には、、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を継続し、洗浄水が人体に当たらない状態で前記洗浄水を系外に吐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内に流入しても、洗浄水が人体に噴出しない洗浄ノズルの位置で、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することができる。
【０００９】
また、請求項３は、洗浄水を貯留する洗浄水貯留手段と、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、人体局部へ向けて洗浄水を噴出する洗浄用ノズルと、前記洗浄用ノズルを駆動するノズル駆動手段と、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、前記洗浄水温度検知手段による検知温度が第１の設定値以上の高温である場合には、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か、又は所定の制限時間が経過するまで給水を継続し、洗浄水が人体に当たらない状態で前記洗浄水を系外に吐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内に流入し、洗浄水が人体に噴出しない洗浄ノズルの位置で給水を続け、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、移動体内の水を多量に無駄に捨てることがないようにすることができる。
【００１０】
また、請求項４は、請求項３に記載の衛生洗浄装置において、前記制限時間が経過したときに前記洗浄水温度検知手段の検知温度が第２の設定値以上であれは、再度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か、又は所定の前記制限時間が経過するまで給水を継続して洗浄水が人体に当たらない状態で前記洗浄水を系外に吐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内に流入し、洗浄水が人体に噴出しない洗浄ノズルの位置で給水を続けても、設定回数しか行わないため、移動体の運転が比較的長時間であっても、移動体内の水を多量に無駄に捨てることがないようにすることができる。
【００１１】
また、請求項５は、洗浄水を貯留する洗浄水貯留手段と、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、人体局部へ向けて洗浄水を噴出する洗浄用ノズルと、前記洗浄用ノズルを駆動するノズル駆動手段と、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、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、洗浄水が人体に当たらない状態で所定時間給水して前記洗浄水を系外に吐水を行い、前記所定時間経過後前記吐水を停止して前記洗浄ノズルを収納する一連の動作を、前記検知温度が設定温度以下になるまで最大で所定の回数繰り返し、前記所定回数繰り返した場合は使用者の吐水指示を拒否する吐水禁止モードに移行させ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内に流入し、洗浄水が人体に噴出しない洗浄ノズルの位置で給水を続けても、設定回数しか行わないため、移動体の運転が比較的長時間であっても、移動体内の水を多量に無駄に捨てることがないようにすることができる。
【００１２】
また、請求項６は、洗浄水を貯留する洗浄水貯留手段と、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、人体局部へ向けて洗浄水を噴出する洗浄用ノズルと、前記洗浄用ノズルを駆動するノズル駆動手段と、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、前記洗浄水温度検知手段による検知温度が第１の設定値以上の高温である場合には、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洗浄水が人体に当たらない状態で前記洗浄水を系外に吐水する一連の動作を所定の回数繰り返し、前記所定回数繰り返した場合は使用者の吐水指示を拒否する吐水禁止モードに移行させ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内に流入し、洗浄水が人体に噴出しない洗浄ノズルの位置で給水を続けても、設定回数しか行わないため、移動体の運転が比較的長時間であっても、移動体内の水を多量に無駄に捨てることがないようにすることができる。

【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。
【実施例】
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。
【００１４】
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。また、ノズル装置１４には、洗浄水を人体局部へあてるため、ノズルを駆動するノズルモータを備えている。
【００１５】
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。
【００１６】
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。
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、衛生洗浄装置が着脱され、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。（ここでは詳細略）
【００１７】
図２に本発明における請求項１の制御内容をフローチャートで示している。ここでは洗浄水温度検出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、洗浄ＳＷＯＮ後、（Ｓ１０１）でノズルを洗浄位置へ駆動させ、（Ｓ１０２）で電磁弁をＯＮさせ給水を開始し、（Ｓ１０３）でサーミスタの温度が設定値Ｔ１より低ければ、（Ｓ１０４）で止信号が入力されるまで、（Ｓ１０３）に戻る。ここで、止信号とは、洗浄停止ＳＷＯＮや、着座検出信号ＯＦＦなどである。（Ｓ１０３）でサーミスタ温度が設定値Ｔ１より高ければ、（Ｓ１０５）で電磁弁をＯＦＦして給水を停止し、（Ｓ１０６）でノズルを捨水位置へ駆動させる。ここで、捨水位置とは、ノズルから噴出する水が人体に当たらない位置であり、例えば、ノズル収納状態で、ノズルから噴出する水はノズルを収納するケースなどに当たって、人体には当たらずに便器内へ落ちる。次に、（Ｓ１０７）でタイマをスタートさせ、時間を計測してから、（Ｓ１０８）で電磁弁をＯＮし給水を開始する。（Ｓ１０９）でタイマのカウントが設定値になった後、に、（Ｓ１１０）で電磁弁をＯＦＦし給水を停止させ、（Ｓ１１１）でノズルを収納位置へ駆動させ、洗浄待機状態へ移る。これにより、洗浄動作中に、一時的に高温の水が流入してきても、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。
【００１８】
図３に本発明における請求項２の制御内容をフローチャートで示している。ここでは洗浄水温度検出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、洗浄ＳＷＯＮ後、（Ｓ２０１）でノズルを洗浄位置へ駆動させ、（Ｓ２０２）で電磁弁をＯＮさせ給水を開始し、（Ｓ２０３）でサーミスタの温度が設定値Ｔ１より低ければ、（Ｓ２０４）で止信号が入力されるまで、（Ｓ２０３）に戻る。ここで、止信号とは、洗浄停止ＳＷＯＮや、着座検出信号ＯＦＦなどである。（Ｓ２０３）でサーミスタ温度が設定値Ｔ１より高ければ、（Ｓ２０５）で電磁弁をＯＦＦして給水を停止し、（Ｓ２０６）でノズルを捨水位置へ駆動させる。ここで、捨水位置とは、ノズルから噴出する水が人体に当たらない位置であり、例えば、ノズル収納状態で、ノズルから噴出する水はノズルを収納するケースなどに当たって、人体には当たらずに便器内へ落ちる。次に、（Ｓ２０７）で電磁弁をＯＮし給水を開始する。（Ｓ２０８）で、サーミスタの温度が設定値Ｔ２より低くなれば、（Ｓ２０９）で電磁弁をＯＦＦし給水を停止させ、（Ｓ２１０）でノズルを収納位置へ駆動させ、洗浄待機状態へ移る。これにより、洗浄動作中に、一時的に高温の水が流入してきても、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。
【００１９】
図４に本発明における請求項３の制御内容をフローチャートで示している。ここでは洗浄水温度検出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、洗浄ＳＷＯＮ後、（Ｓ３０１）でノズルを洗浄位置へ駆動させ、（Ｓ３０２）で電磁弁をＯＮさせ給水を開始し、（Ｓ３０３）でサーミスタの温度が設定値Ｔ１より低ければ、（Ｓ３０４）で止信号が入力されるまで、（Ｓ３０３）に戻る。ここで、止信号とは、洗浄停止ＳＷＯＮや、着座検出信号ＯＦＦなどである。（Ｓ３０３）でサーミスタ温度が設定値Ｔ１より高ければ、（Ｓ３０５）で電磁弁をＯＦＦして給水を停止し、（Ｓ３０６）でノズルを捨水位置へ駆動させる。ここで、捨水位置とは、ノズルから噴出する水が人体に当たらない位置であり、例えば、ノズル収納状態で、ノズルから噴出する水はノズルを収納するケースなどに当たって、人体には当たらずに便器内へ落ちる。次に、（Ｓ３０７）でタイマをスタートさせ、（Ｓ３０８）で電磁弁をＯＮし給水を開始する。（Ｓ３０９）で、サーミスタの温度が設定温度Ｔ２より低くなれば、（Ｓ３１１）で電磁弁をＯＦＦし給水を停止させ、（Ｓ３１２）でノズルを収納位置へ駆動させ、洗浄待機状態へ移る。（Ｓ３０９）でサーミスタ温度が設定値Ｔ２より高いままであっても、（Ｓ３１０）でタイマのカウントが設定値になれば、（Ｓ３１１）で電磁弁をＯＦＦし給水を停止させ、（Ｓ３１２）でノズルを収納位置へ駆動させ、洗浄待機状態へ移る。これにより、洗浄動作中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、多量の水を無駄に捨てることがなくてすむ。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a sanitary washing device which is installed in a toilet and performs hot water washing of a local part of a human body.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, in a sanitary washing apparatus that performs hot water washing of a human body local part, there is a sanitary washing apparatus that stops a washing function when washing water reaches a certain temperature or higher (for example, see Patent Document 1).
[0003]
[Patent Document 1]
Japanese Utility Model Application Laid-Open No. 5-25696
This is to prevent high-temperature water from directly splashing on the human body, such as when the sanitary washing device breaks down, and to prevent harm such as burns. On the other hand, in the case of a sanitary washing device installed in a moving body that has caused the following inconveniences, for example, a camper, etc., the piping is heated by a tape heater or the like to prevent the piping from freezing in cold regions or winter. are doing. If the temperature control of the tape heater is rough, the water in the pipe connected to the hot water cleaning device temporarily becomes high in temperature, and the high-temperature water is stored in the cleaning water storage means while using the cleaning function of the sanitary cleaning device. And the control means disables the cleaning function of the sanitary washing device for safety due to the signal from the washing water temperature detecting means.
[0005]
[Problems to be solved by the invention]
However, the water in the pipes connected to the sanitary washing device is often hot enough to affect the human body in a part of the pipes. Since the washing function is disabled even though the equipment is usable, high-temperature water remains in the washing water storage means even if the user resets the power of the sanitary washing equipment. Because the control means keeps the washing operation stopped, it is necessary to drain the water in the washing water storage means or wait for the water in the washing water storage means to radiate heat naturally and reduce the temperature, It was inconvenient for the user.
[0006]
The present invention is intended to solve such a problem, and even if a part of water in a pipe connected to a sanitary washing device is at a high temperature, the washing function can be used without bothering the user. It is an object of the present invention to provide a sanitary washing device for canceling the disabled state.
[0007]
[Means for Solving the Problems]
In order to solve the above problem, claim 1 is a cleaning water storing means for storing cleaning water, a water supply control means for controlling water supply from a water supply port to the cleaning water storage means, and a cleaning water from a water supply port. Washing water temperature detecting means for detecting a temperature, a washing nozzle for jetting washing water toward a human body part, a nozzle driving means for driving the washing nozzle, and a high temperature at which the washing water temperature detecting means is equal to or higher than a set value. A sanitary washing device having control means for stopping water supply when water is detected, if the temperature detected by the wash water temperature detecting means is a high temperature equal to or higher than a set value, water supply is continued until a predetermined time elapses. The washing water is discharged outside the system in a state where water does not hit a human body. As a result, even if high-temperature water heated in a part of the piping in the moving body flows into the sanitary washing device, the washing water is continuously supplied at a position of the washing nozzle where the washing water does not squirt to the human body. The signal from the detection means can prevent the control means from disabling the cleaning function of the sanitary washing device for safety.
[0008]

BEST MODE FOR CARRYING OUT THE INVENTION
In order to make the contents of the present invention easier to understand, the present invention will be described in detail with reference to the following examples.
【Example】
FIG. 1 shows a block diagram of a main part of a sanitary washing device according to the present invention. In FIG. 1, a water supply unit 1, a filter 2, a check valve 3, and a pressure regulating valve 4 are sequentially connected to a water supply pipe for supplying cleaning water from an upstream side. The downstream side of the pressure regulating valve 4 is connected to an electromagnetic valve 7 that controls the flow of water through the flow path. The downstream side of the solenoid valve 7 is connected to a hot water tank 9 via a safety valve 8. In the hot water tank 9, a hot water heater 10, a float SW11 for detecting full water, and a hot water thermistor 16 for detecting the temperature in the hot water tank are provided. Normally, a read SW that detects magnetism and turns on / off is used as the float SW 11.
[0014]
Further, a vacuum breaker 12 is connected downstream of the hot water tank 9, and a flow path switching and flow rate adjusting valve 13 is further connected thereto. The downstream side of the flow path switching and flow rate regulating valve 13 is connected to a nozzle device 14 for ejecting the washing water to the human body. In addition, the nozzle device 14 is configured with three flow paths, a bottom cleaning flow path, a soft cleaning flow path, and a bidet cleaning flow path, and the flow paths can be appropriately switched according to an instruction from the control unit 5. Further, the nozzle device 14 is provided with a nozzle motor for driving the nozzle in order to apply the washing water to the human body part.
[0015]
With the above configuration, the washing water supplied from the water supply unit 1 by the opening operation of the electromagnetic valve 7 is heated by the hot water tank 9 to hot water at an appropriate temperature, pushes up the vacuum breaker 12, and moves to the flow path switching and flow control valve 13. Reach. Here, the flow rate of the washing water is adjusted by the flow path switching and flow control valve 13 and is ejected from the nozzle device 14 through the selected flow path.
[0016]
Further, the control means 5 is controlled by receiving a signal from the seating detection means 6. Here, the seating detection means 6 is a photoelectric reflection sensor. The seating detecting means 6 emits an infrared ray, judges the presence or absence of the object based on the level of light reflected from the object (human body), and outputs the result to the control means 5.
Further, the control means 5 is controlled by receiving a signal from the attachment / detachment detection means 15. Here, the attachment / detachment detecting means 15 is usually composed of a sanitary washing device, a toilet and an attachment mechanism. The attachment / detachment detecting means 15 is constituted by a micro SW or the like protruding from a mounting surface of the sanitary washing device and the toilet, and has a structure in which the sanitary washing device is attached / detached and turned off when the sanitary washing device rises from the toilet surface.

Here, the stop signal is, for example, a cleaning stop SW ON or a seating detection signal OFF. If the thermistor temperature is higher than the set value T1 in (S103), the solenoid valve is turned off in (S105) to stop water supply, and in (S106), the nozzle is driven to the draining position. Here, the water drainage position is a position where water jetting from the nozzle does not hit the human body.For example, in the nozzle storage state, water jetting from the nozzle hits a case or the like that stores the nozzle and does not hit the human body.

Here, the water drainage position is a position where water jetting from the nozzle does not hit the human body.For example, in the nozzle storage state, water jetting from the nozzle hits a case or the like that stores the nozzle and does not hit the human body. Fall into the toilet bowl. Next, in (S207), the solenoid valve is turned on to start water supply. If the temperature of the thermistor becomes lower than the set value T2 in (S208), the electromagnetic valve is turned off in (S209) to stop water supply, and in (S210), the nozzle is driven to the storage position to shift to a cleaning standby state.

Fall into the toilet bowl. Next, the timer is started in (S307), and the electromagnetic valve is turned on in (S308) to start water supply. If the temperature of the thermistor is lower than the set temperature T2 in (S309), the solenoid valve is turned off in (S311) to stop water supply, and in (S312), the nozzle is driven to the storage position to shift to the cleaning standby state. Even if the thermistor temperature remains higher than the set value T2 in (S309), if the timer count reaches the set value in (S310), the solenoid valve is turned off in (S311) to stop water supply, and (S312) The nozzle is driven to the storage position, and the state shifts to the washing standby state. Thus, if the temperature of the thermistor is higher than the set value during the cleaning operation, the water supply is continued.
