Description
以下、本発明を図1〜図4に示す一実施形態にもとづいて説明する。
Claims (4)
- 開口する切欠き部が形成された合成樹脂製のカバーを有するケーシングと、
前記ケーシング内に設けられ、該ケーシング内を保温する保温ヒータと、
少なくともその一部に光が透過し、前記切欠き部を塞ぐ本体部分、及び、前記ケーシングの前記切欠き部の周囲の内面と重なるように取着されるフランジ部を有し、前記切欠き部の周囲の内面に前記フランジ部が組み付くことで前記光が透過する窓部を前記ケーシングに形成するとともに、前記保温ヒータに直接接触すると前記保温ヒータの熱により熱変形が生じる透明部材と、
前記ケーシング内に設けられ、前記窓部を通じて、降雪現象となる雪片を検出する雪片検出センサと、
少なくとも前記フランジ部と重なり合う枠形板部を有し、前記保温ヒータと接触する、熱良導体で形成された放熱部材と、
を具備し、
前記放熱部材は、前記保温ヒータから伝熱された熱の一部を、前記ケーシング内部へ放熱することを特徴とする降雪センサ装置。 - さらに、前記ケーシング内は、熱遮蔽手段によって前記保温ヒータを含む熱源から熱的に遮蔽された領域と、この領域に配置され降雪現象となる外気温を検出する気温センサとを有することを特徴とする請求項1に記載の降雪センサ装置。
- 前記熱遮蔽手段は、前記ケーシング内において前記保温ヒータを含む熱を発生する機器から、前記気温センサを遠ざけた地点に配置し、これら間のケーシング内部空間を隔壁で仕切ることで構成されることを特徴とする請求項2に記載の降雪センサ装置。
- 前記気温センサは、前記ケーシングを構成する各部のうち、外面が外気に露出する熱伝導性の良い部材の内面に対し、検出部を接触させて取り付けてあることを特徴とする請求項2または請求項3に記載の降雪センサ装置。
