Abstract
【解決手段】 水槽等の底部に横置状態にして水を加熱するヒータ2を内装した管状の本体1の周囲の3方に、周方向に等間隔毎に感知センサT1〜T3を配設して、横置状態のヒータ2から少なくとも1本の感知センサを上方に位置させるように構成し、この感知センサの電極端子が気中に露出した時にヒータ2への通電を停止させるように回路構成を形成している。

Claims (3)
- 水槽等内に投入して水を所定温度にまで加熱する装置であって、ヒータを内装している管状の本体の周囲に、この本体を中心として周方向に所定間隔毎に水中と気中との違いを感知する少なくとも3本の感知センサを配設し、これらの感知センサの少なくとも一本の感知センサの電極端子が気中に露呈した時にヒータに対する電源からの通電を遮断するように構成したことを特徴とする水槽等の加熱装置。
- ヒータ本体の長さ方向の先端部に湯水中と気中との違いを感知する少なくとも1本の別な感知センサを配設していることを特徴とする請求項1に記載の水槽等の加熱装置。
- 感知センサの電極端子が湯水中にある場合に発振出力し、気中にある場合に発振出力しない高周波発振回路を各感知センサごとに接続し、これらの全ての高周波発振回路からの電圧と基準電圧とを比較回路により比較していずれか1つの高周波発振回路からでも電圧が低くなった時に電源からの通電を遮断するように構成したことを特徴とする請求項1又は請求項2に記載の水槽等の加熱装置。
