Claims (3)
- ベースとカバーとからハウジングが構成され、前記ハウジングの内部に熱線を検知する焦電素子が設けられ、前記ハウジングには焦電素子に熱線を収束させるレンズを配してなる熱線式検知器であって、
前記ハウジングには、設置状態における下端部に水抜き孔を設けてなるとともに、ハウジングの内部であって前記水抜き孔の近傍に、該水抜き孔から侵入した空気流が焦電素子に向かうことを阻止する風防壁が設けられ、
前記風防壁は、前記水抜き孔に対向する側の壁面が凹形状であり、該風防壁によって前記ハウジング内に風除室が区画形成されたことを特徴とする熱線式検知器。 - 前記ベースには、焦電素子が固定されるとともに、焦電素子に対するレンズの位置決めをする位置規制部材を設け、
レンズは、前記位置規制部材と前記カバーとにより挟持されるようにしたことを特徴とする請求項1記載の熱線式検知器。 - 前記焦電素子を一対並設し、各々の焦電素子に対応させてレンズも一対並設し、一方の焦電素子及びレンズと他方の焦電素子及びレンズとは、互いに角度を成すように配設したことを特徴とする請求項1又は請求項2に記載の熱線式検知器。
