Cold air controlling device and method for refrigerator

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.

Description

technical field [0001] The present invention relates to refrigerators and, more particularly, to an apparatus for controlling cold air to concentrate cooling on poorly cooled areas or to store new loads. Background technique [0002] Generally, refrigerators are used to freeze food, or to maintain the same temperature during frozen storage. [0003] A refrigerator is a refrigeration cycle that draws heat from the surrounding environment and cools it through a refrigeration cycle consisting of air compression, air condensation, and evaporation steps to freeze or refrigerate food that has spoiled in warm areas, and food such as fish that requires freshness Devices for class products. [0004] Because based on the above principles, refrigerators can conveniently store food, fish, fruits, beverages, etc. at any time, and freeze them into edible ice, so refrigerators have become indispensable electrical equipment in modern society.

Problems solved by technology

[0019] However, according to this cold air control method, when the ambient temperature of the refrigerating room rises and the weight increases due to the new load as described above, the cold air is discharged into the entire refrigerating room for a certain period of time, so that Reduce the elevated ambient temperature of the entire refrigerator, thus detrimentally increasing the power consumption of the refrigerator

[0020] In addition, the control method of the cooling of the whole refrigerating room mentioned above is to cool the newly stored load while lowering the temperature of the whole refrigerating room, therefore, the cooling speed of the new load is greatly reduced and the ability of the cold air to cool the refrigerator is reduced, which is a shortcoming
