ABSTRACT:
A concentrated cooling apparatus of a refrigerator is capable of improving the reliability of an infrared sensor by preventing moisture from being condensed onto the surface of the infrared sensor. The concentrated cooling apparatus includes a nozzle rotationally supported by a cold air guide path, the nozzle intensively jetting cold air to a high-temperature load region when a high-temperature load is placed inside a chilling chamber of the refrigerator. An infrared sensor is installed at the front of the nozzle, and the infrared sensor senses the high-temperature load region while being rotated together with the nozzle. A moisture removing device is formed at a side of the nozzle, the moisture removing device jetting cold air on the surface of the infrared sensor to remove moisture condensed on the surface of the infrared sensor.
