Claims (1)
て、被検出面から反射光を直接受けない角度で光
を照射する如く配置された発光素子と、上記被検
出面に付着した霜による乱反射光を発光素子と同
等の角度で受光する如く配置された受光素子とを
備えたことを特徴とするフロストセンサ。 A frost sensor that optically detects frost formation includes a light-emitting element arranged to emit light at an angle that does not directly receive reflected light from the detection surface, and a light-emitting element that emits light diffusely reflected by frost attached to the detection surface. and a light receiving element arranged to receive light at an angle equivalent to that of the frost sensor.
