Abstract

The invention provides a refrigerating and freezing device. The device comprises a box body and a magnetic air separation unit; a storage space and an air supply air duct are defined in the box body,wherein the air supply air duct is used for conveying cold air flows to the storage space; a first storage container and a second storage container which are distributed at intervals are arranged in the storage space, and each of the first storage container and the second storage container is provided with an air inlet; the magnetic air separation unit is used for communicating an air outlet of the air supply air duct with the air inlet of the first storage container and the air inlet of the second storage container, and is configured to separate oxygen from nitrogen in the cold air flows so as to form the oxygen-enriched cold air flows and the nitrogen-enriched cold air flows; and the oxygen-enriched cold air flows are introduced into the first storage container to form an oxygen-enrichedfresh-keeping space in the first storage container, the nitrogen-enriched cold air flows are introduced into the second storage container to form a nitrogen-enriched fresh-keeping space in the secondstorage container, so that the quality, color and lustre of meat can be guaranteed, and nutrition loss can be reduced; and aerobic respiration intensity of fruits and vegetables can be reduced, so that deterioration of the fruits and vegetables can be inhibited, and nutrient loss can be reduced.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a refrigeration and freezing device. Background technique [0002] At present, the schemes for achieving controlled atmosphere and low oxygen in refrigerators are mainly pressure swing adsorption or oxygen-enriched membrane separation. [0003] Pressure swing adsorption is to use the air compressor to absorb the air in the air or the air in the refrigerator, inject it into the adsorption bed, realize the separation of nitrogen and oxygen in the adsorption bed, nitrogen is discharged into the compartment to achieve the effect of freshness, and oxygen is discharged as waste gas . [0004] Oxygen-enriched membrane separation uses a vacuum pump to provide a pressure difference on both sides of the oxygen-enriched membrane, so that oxygen molecules with a faster diffusion rate enter the membrane through the surface of the membrane, and are sucked out by the vacuum pump t...
