Abstract
The utility model relates to an improved freshness-retaining structure for refrigerators. A gas separation film device which has a macromolecule semi-permeable film is arranged in the refrigerator. The gas separation film device is connected and provided with a pump and a discharge pipe, so that the oxygen component generated through the gas separation film device in the refrigerator is discharged forcibly out of the refrigerator via the discharge pipe. The gas separation film device is arranged in the refrigerator to separate the oxygen and the nitrogen in the refrigerator and discharge the oxygen out of the refrigerator, which increases the nitrogen component in the refrigerator and achieves the purpose of filling passive gas into the refrigerator. Thus, the refrigerator not only has good food preserved function, but also has nitrogen increased function, which can effectively provide better quality of the preserved food. The nitrogen which is colourless, tasteless and nontoxic is the passive gas. The nitrogen of the gas separation film device is obtained by the increment of the natural nitrogen content in the air, which reduces the oxygen concentration in the refrigerator and facilitates the delay of the foodstuff oxidation, and thereby, better preserving efficacy can be achieved.
