Abstract
Description
図1〜図4に示すように、給湯装置1は、給湯機器や暖房機器等の熱源機として適用されるものであり、燃料ガスを燃焼して燃焼ガスに含まれる熱を利用して水又は湯水の加熱を行うガス給湯器を構成している。
図2,図3に示すように、給湯装置1は、熱交換器缶体22の表面温度を検知する為の温度検知センサ31(温度検知手段に相当する)を備えている。温度検知センサ31は、給湯運転時には常時燃焼する燃焼段11b(燃焼部)の直上であって、熱交換器21の燃焼段11bに最も近い下段熱交換領域21Bの伝熱管25の下流側の近傍において熱交換器缶体22の表面に設けられている。
図1,図2に示すように、制御ユニット7は、給湯装置1の制御を行うものであり、各種のセンサが電気的に接続され、各種のセンサからの検知信号を受信するように構成されている。制御ユニット7は、操作リモコン等によって設定された給湯温度、給湯栓に供給される給湯量、各種のセンサから受信した検知信号に基づき、送風ファン2やバーナーユニット11等を駆動制御し、給湯運転を実行する。
制御ユニット7(判定手段に相当する)は、温度検知センサ31によって検知される検知温度(熱交換器缶体22の表面温度)が設定温度以上になった場合に熱交換器21の伝熱管25内にスケールが堆積していると判定するスケール詰まり判定運転制御を実行可能である。
本発明の給湯装置1は、熱交換器缶体22の表面温度を検知する為の温度検知センサ31と、この温度検知センサ31によって検知される検知温度が設定温度以上になった場合に熱交換器21の伝熱管25内にスケールが堆積していると判定する制御ユニット7とを備えたので、熱交換器缶体22の表面温度が設定温度以上になった場合、熱交換器21にスケール詰まりが発生したと把握することができる。
[1]前記実施例の温度検知センサ31は、直管部27bの通路部32の近傍における熱交換器缶体22の前側板22aの表面に設けられているが、この位置に限定する必要はなく、伝熱管25内で湯水温度が最も上昇する可能性がある通路部の近傍であれば、適宜変更可能である。
