Abstract

The invention provides a refrigerating and freezing device, which includes a box body and a magnetic air separation unit. The box body defines a storage space and an air supply duct for delivering cold air flow to the storage space. The first storage container and the second storage container, the first storage container and the second storage container are formed with air inlets, and the magnetic air separation unit is used to connect the air outlet of the air supply duct to the first storage container respectively. The air inlet of the container communicates with the air inlet of the second storage container, and is configured to separate oxygen and nitrogen in the cold air flow to form an oxygen-enriched cold air flow and a nitrogen-enriched cold air flow, and flow the oxygen-enriched cold air flow into the first storage In the container, the nitrogen-enriched cold air flows into the second storage container to form an oxygen-enriched fresh-keeping space in the first storage container, and a nitrogen-enriched fresh-keeping space in the second storage container, which can ensure the quality of the meat It can improve color and reduce nutrient loss, and can also reduce the intensity of aerobic respiration of fruits and vegetables, inhibit the deterioration of fruits and vegetables and reduce nutrient loss.

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...
