【0004】
【発明が解決しようとする課題】
しかしながら、このような温度センサ本体を改良して温度検知の応答性を高める方法は設計及び製造方法の変更を必要とする為、開発コスト・製造コストの増加は免れなかった。
【0005】
本発明は、温度センサを取付けるプリント基板にわずかな変更を加えるだけで上述した温度センサの応答性を高める方法を提供するものである。
【0006】
【課題を解決するための手段】
上記課題を解決するために、請求項1に記載の発明は、室内温度を検出する感熱部と該感熱部から延びるリード線とを有する温度センサと、前記温度センサのリード線を制御回路が構成されるプリント基板上に接着し室内温度を検出して空気調和機等の運転を制御する機器において、前記プリント基板には前記リード線の取付け部の周囲にスリットを設けると共に、前記プリント基板上の前記温度センサおよび前記リード線の周囲に区画する立上部を設けたことである。
【0007】
請求項1に記載の発明には、次の作用がある。上述の温度センサを取付けたプリント基板は、該プリント基板上に制御回路が構成されており、通電によって制御回路自身が発熱することによりプリント基板を加熱する、この熱は熱伝導によりプリント基板上の温度センサ取付け部へと至り温度センサに影響を与えるため、このプリント基板の温度センサ取付け部周囲にスリットを設けると共に、前記プリント基板上の前記温度センサおよび前記リード線の周囲に区画する立上部を設けることにより、制御回路からプリント基板の熱伝導により伝わる熱を遮断し、室内温度を温度センサで正確に検出する。
【0008】
請求項2に記載の発明は、室内温度を検出する感熱部ろ該感熱部から延びるリード線とを有する温度センサと、前記感熱素子を制御回路が構成されるプリント基板上に接着し室内温度を検出して空気調和機等の運転を制御する機器において、前記プリント基板の感熱素子を接着する周囲に、室温検知精度を向上させるためのパターン配線を設けると共に、前記プリント基板上の前記温度センサおよび前記リード線の周囲に区画する立上部を設けることである。
【0009】
