Title: REFRIGERATION/FREEZING DEVICE
Abstract:
A refrigeration/freezing device is provided. The refrigeration/freezing device comprises: a container (20), wherein a storage space (211) is defined in the container (20), a storage container is disposed in the storage space (211), and a modified atmosphere preservation space is provided in the storage container; a modified atmosphere film assembly (30), configured such that the amount of oxygen from airflow around the modified atmosphere film assembly (30) and passing through the modified atmosphere film assembly (30) into an oxygen-enriched gas collection chamber is greater than the amount of nitrogen from the airflow around the modified atmosphere film assembly (30) and passing through the modified atmosphere film assembly (30) into the oxygen-enriched gas collection chamber; and a gas suction pump (41), wherein the gas suction pump (41) is disposed at the top of the container (20), and an inlet end of the gas suction pump (41) communicates with the oxygen-enriched gas collection chamber by means of a pipeline and the modified atmosphere film assembly (30), such that the gas entering the oxygen-enriched gas collection chamber is sucked out of the storage container.
