Title:
INTENSIVE COOLING DEVICE FOR REFRIGERATOR
Document Type and Number:
Japanese Patent JP3727919
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an intensive cooling device for a refrigerator capable of quickly and uniformly keeping temperature change inside a cold room and preventing condensation on a lens surface of an infrared sensor detecting generation of a high temperature load for improving reliability of the infrared sensor by arranging the intensive cooling device inside the cold room for intensively discharging cold air to a high temperature load generation area.
SOLUTION: This intensive cooling device for the refrigerator is constructed by including a nozzle 26 supported rotationally in a cold air guide passage 19 for intensively jetting cold air to the high temperature load generation area if the high temperature load is generated in a predetermined area inside the cold room 6, an infrared sensor 28 arranged in front of the nozzle 26 for sensing the high temperature load generation area while turning with the nozzle 26, and a water removing means formed one side of the nozzle 26 and jetting cold air toward the surface of the infrared sensor 28 for removing water condensed on the surface of the infrared sensor.
