  • Patent number: 6848264
    Abstract: An apparatus controls cool air for directedly cooling a section which is weakly cooled or which stores new loads. The apparatus discharges the cool air by rotating a drive body in accordance with a variation of visual images taken by visual image generator before and after the load is stored. The cool air can also be discharged into a specific storage space by rotating cool air injection nozzles based upon the temperature variation of door baskets detected by temperature sensors. Therefore, a uniform temperature distribution can be maintained in the cooling device to substantially reduce an amount of power consumption.

  • Patent number: 6718780
    Abstract: A concentration cooling apparatus for a refrigerator includes a housing which is mounted in a cold air guiding path, and a nozzle which is rotatably supported in the housing, for concentratedly injecting cold air to a region where a high temperature load is generated when the high temperature load is generated in a predetermined region inside a cooling chamber. An infrared sensor is mounted at the front of the nozzle, for sensing the region where the high temperature load is generated. The sensor rotates together with the nozzle and a frost drying sensor is installed on the upper surface of the nozzle, for drying frost on the surface of the infrared sensor. Thus, the reliability of the infrared sensor can be improved by preventing the formation of frost on the surface of the lens of the infrared sensor which detects whether the high temperature load is generated.
