Abstract:
1. A concentrated cooling apparatus of a refrigerator, comprising: a nozzle rotationally supported by a cold air guide path, the nozzle letting cold air onto a high-temperature load region when a high-temperature load is placed inside a chilling chamber of the refrigerator; an infrared sensor installed at the front of the nozzle, the infrared sensor sensing the high-temperature load region while being rotated with the nozzle; a moisture removing device provided 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; a cold air jet opening provided at a side of the nozzle to jet cold air of the cold air guide path to the high-temperature load region; and a sensor receiving groove that receives the infrared sensor is provided parallel with the cold air jet opening on the side of the nozzle, wherein the moisture removing device comprises a cold air discharge opening connecting the sensor receiving groove with the cold air jet opening, and the cold air discharge opening jets part of the cold air passing through the cold air jet opening onto the sensor receiving groove.
