Abstract

<P>PROBLEM TO BE SOLVED: To start heating for a bathroom simultaneously with the time a switch is depressed to supply hot water into a bathtub for bathing. <P>SOLUTION: When it is detected that an automated switch 20 of a remote controller 1 for a heat source machine is depressed with automatic switch judgement means 31, an instruction signal for starting bathroom heating operation is transmitted to a bathroom heater controller 8 via bathroom heater communication means 6. Successively, an instruction signal for starting heating operation is outputted from the bathroom heater controller 8 to start heating operation for a bathroom heater 3. Consequently, a user can start the heating operation for the bathroom heater 3 only by operating the automated switch 20 of the heat source machine remote controller 1 without operating the bathroom heater remote controller 2. <P>COPYRIGHT: (C)2004,JPO

【0024】
次に本発明の第1の手段の動作について説明する。熱源機リモコン1の自動スイッチ20をオンすると浴槽19へ湯張りを開始する。この際、自動スイッチ判定手段31により自動スイッチ20がオンされたことを検出すると、暖房運転連動手段7が浴室暖房機3が接続されていると認識している場合に、浴室暖房運転開始の指示を浴室暖房機通信手段6を介して浴室暖房機制御装置8に通信する。
【0025】
浴室暖房機制御装置8は浴室暖房機リモコン2に暖房運転開始の指示を出し、浴室暖房機3の暖房運転を開始させる。このようにすることで使用者は、浴室暖房機リモコン2の操作をせずに熱源機リモコン1の自動スイッチ20を操作するだけで、浴室暖房機3の暖房運転を開始することができる。
【0026】
第2の手段では、熱源機リモコン1の追いだきスイッチ21をオンすると循環ポンプ16を回転させ、浴槽19内の湯を循環するとともに、ふろ熱交換器11により加熱した湯を浴槽19へ供給する。この際、追いだきスイッチ判定手段32により追いだきスイッチ21がオンされたことを検出すると、暖房運転連動手段7が浴室暖房機3が接続されていると認識している場合に、浴室暖房運転開始の指示を浴室暖房機リモコン通信手段6を介して浴室暖房機制御装置8に通信する。浴室暖房機制御装置8は浴室暖房機リモコン2に暖房運転開始の指示を出し、浴室暖房機3の暖房運転を開始させる。このようにすることで使用者は、浴室暖房機リモコン2の操作をせずに熱源機リモコン1の追いだきスイッチ21を操作するだけで、浴室暖房機3の暖房運転を開始することができる。
【0027】
第3の手段では、熱源機リモコン1の足し湯スイッチ22をオンすると浴槽19へ所定湯量の湯張りを開始する。この際、足し湯スイッチ判定手段33により足し湯スイッチ22がオンされたことを検出すると、暖房運転連動手段7が浴室暖房機3が接続されていると認識している場合に、浴室暖房運転開始の指示を浴室暖房機リモコン通信手段6を介して浴室暖房機制御装置8に通信する。浴室暖房機制御装置8は浴室暖房機リモコン2に暖房運転開始の指示を出し、浴室暖房機3の暖房運転を開始させる。このようにすることで使用者は、浴室暖房機リモコン2の操作をせずに熱源機リモコン1の足し湯スイッチ22を操作するだけで、浴室暖房機3の暖房運転を開始することができる。
【0028】
第4の手段では、熱源機リモコン1のぬるめスイッチ23をオンすると浴槽19へ所定湯量の水張りを開始する。この際、ぬるめスイッチ判定手段34によりぬるめスイッチ23がオンされたことを検出すると、暖房運転連動手段7が浴室暖房機3が接続されていると認識している場合に、浴室暖房運転開始の指示を浴室暖房機リモコン通信手段6を介して浴室暖房機制御装置8に通信する。浴室暖房機制御装置8は浴室暖房機リモコン2に暖房運転開始の指示を出し、浴室暖房機3の暖房運転を開始させる。このようにすることで使用者は、浴室暖房機リモコン2の操作をせずに熱源機リモコン1のぬるめスイッチ23を操作するだけで、浴室暖房機3の暖房運転を開始することができる。
【0029】
第5の手段では、浴槽19に湯張りが完了している状態で、人間が入浴すると、水位センサー13からの信号を人はいり検出手段30が検出すると、暖房運転連動手段7が浴室暖房機3が接続されていると認識している場合に、浴室暖房運転開始の指示を浴室暖房機通信手段6を介して浴室暖房機制御装置8に通信する。浴室暖房機制御装置8は浴室暖房機リモコン2に暖房運転開始の指示を出し、浴室暖房機3の暖房運転を開始させる。このようにすることで使用者は、浴室暖房機リモコン2の操作をせずに、浴室暖房機3の暖房運転を開始することができる。
【0030】
第6の手段では、自動スイッチ20の操作により浴槽19に湯張りが完了すると、熱源機リモコン1の設定温度に浴槽19の温度を保温しておく。保温する時間は、熱源機リモコン1により設定できる(例えば、0、1、2、3、4、6、7、8時間)。前記手段により浴室暖房機3の暖房運転を開始させた場合には、保温時間判定手段37が保温時間の経過を検出すると、暖房運転連動手段7が浴室暖房機3が接続されていると認識している場合に、浴室暖房運転停止の指示を浴室暖房機リモコン通信手段6を介して浴室暖房機制御装置8に通信する。浴室暖房機制御装置8は浴室暖房機リモコン2に暖房運転停止の指示を出し、浴室暖房機3の暖房運転を停止させる。このようにすることで使用者は、浴室暖房機リモコン2の操作をせずに、浴室暖房機3の暖房運転を停止することができ、かつ使用者が浴室暖房機リモコン2を消し忘れた場合でもオフできるので経済的である。
【0031】
第7の手段では、熱源機リモコン1の自動スイッチ20のオンで浴室暖房機3の暖房運転を行う場合でも、夏季の場合には暖房運転連動させる必要はない。使用者が暖房運転連動が必要な場合に、熱源機リモコン1の暖房運転連動切換スイッチ35により、暖房運転連動手段7が浴室暖房運転開始の指示を出すか否かの判断を行うことで、必要な時だけ浴室暖房機3の暖房運転連動を行うことができる。
【0032】
第8の手段では、暖房運転連動手段7が浴室暖房機3が接続されていると認識し、浴室暖房運転開始の指示を出して浴室暖房機3の暖房運転をしている場合、熱源機リモコン1の暖房運転連動時間スイッチ25が暖房運転連動させる時間を設定してあると、暖房運転連動時間判定手段36により、暖房運転時間が設定時間の経過を検出すると、浴室暖房運転停止の指示を浴室暖房機リモコン通信手段6を介して浴室暖房機制御装置8に通信する。浴室暖房機制御装置8は浴室暖房機リモコン2に暖房運転停止の指示を出し、浴室暖房機3の暖房運転を停止させる。このようにすることで使用者は、浴室暖房機リモコン2の暖房オフ操作をせずに、浴室暖房機3の暖房運転を停止することができ、かつ使用者が浴室暖房機リモコン2を消し忘れた場合でもオフできるので経済的である。
【0033】
第9の手段では、熱源機リモコン1の自動スイッチ20のオンで浴室暖房機3の暖房運転を行う場合でも、夏季の場合には暖房運転連動させる必要はない。したがって冬季か否かの判定を吸気温度検出手段29により行い、暖房運転連動手段7が浴室暖房運転開始の指示を出すか否かの判断を行うことで、使用者の手を煩わせることなく必要な時だけ浴室暖房機3の暖房運転連動を行うことができる。
【0034】
第10の手段では、熱源機リモコン1の自動スイッチ20のオンで浴室暖房機3の暖房運転を行う場合でも、夏季の場合には暖房運転連動させる必要はない。
【0035】
したがって冬季か否かの判定を入水温度検出手段29により行い、暖房運転連動手段7が浴室暖房運転開始の指示を出すか否かの判断を行うことで、使用者の手を煩わせることなく必要な時だけ浴室暖房機3の暖房運転連動を行うことができる。
【0036】
第11の手段では、熱源機リモコン1の自動スイッチ20のオンで浴室暖房機3の暖房運転を行う場合でも、夏季の場合には暖房運転連動させる必要はない。
【0037】
使用者が暖房運転連動が必要な場合に、熱源機9の暖房運転連動切換判定手段38の切換を行うことにより、暖房運転連動手段7が浴室暖房運転開始の指示を出すか否かの判断を行うことで、必要な時だけ浴室暖房機3の暖房運転連動を行うことができる。
