Infrared sensor assembly and refrigerator having the infrared sensor |
摘要 |
Disclosed are an infrared sensor assembly and a refrigerator having the infrared sensor, in which a location where a heat source is generated is precisely detected by narrowing a receiving angle of an infrared sensor. To this end, the infrared sensor assembly comprises: an infrared sensor fixed to a supporting frame for receiving infrared rays generated at a heat source; a case having the infrared sensor mounted therein and an infrared filter mounted at an upper surface thereof, the infrared filter transmits only the infrared rays; and a receiving range limiting means prolonged from an outer circumference surface of the case with a predetermined height for limiting a range of the infrared rays received into the infrared sensor so as to precisely detect a location of the heat source.
