Abstract

The invention provides a refrigerating and freezing device which comprises a box, a plurality of air-conditioning film components and a sucking pump component, wherein a storage space and a compressor cabin are limited in the box, and a plurality of preservation spaces are arranged in the storage space; each of the air-conditioning film components is equipped with at least one air-conditioning film and an oxygen-rich air collecting chamber and is arranged for causing more oxygen relative to nitrogen in surrounding space airflow of each air-conditioning film component penetrate through the air-conditioning film and enter the oxygen-rich air collecting chamber; and the sucking pump component is arranged in the compressor cabin and is arranged for pumping air in the oxygen-rich air collecting chamber of each preservation space having an air-conditioning requirement out of the preservation space having the air-conditioning requirement. The refrigerating and freezing device provided by the invention utilizes one sucking pump to realize the air conditioning for the plurality of preservation spaces in the storage space, and different atmospheres are realized for different articles stored in different preservation spaces, so that the preservation requirements for different articles can be fully met.

Description

technical field [0001] The invention relates to the field of item storage, in particular to a refrigeration and freezing device. Background technique [0002] With the development of society and the improvement of people's living standards, and people's pace of life is getting faster and faster, people often buy a large number of items placed in various refrigeration and freezing equipment, but for leafy vegetables and melon and fruit foods, refrigeration and freezing The low temperatures in the appliance's storage space not only wrinkle and blotch the skin of these foods, but also affect their original taste and nutrition. [0003] In the fresh-keeping technology of refrigeration and freezing equipment, oxygen is closely related to the oxidation and respiration of food in refrigeration and freezing equipment. The slower the respiration of the food, the lower the oxidation of the food and the longer the preservation time. Reducing the oxygen content in the air has an obvio...
