Gas adjustment control method of refrigerating and freezing equipment and refrigerating and freezing equipment

Abstract

The invention provides a gas adjustment control method of refrigerating and freezing equipment and the refrigerating and freezing equipment. The gas adjustment control method of the refrigerating and freezing equipment comprises the steps of obtaining a trigger operation for starting a gas adjustment fresh-keeping function by a user; determining gas adjustment requirement conditions of a plurality of fresh-keeping spaces according to the trigger operation; driving a pipe switching mechanism to communicate a sucking pump to pipes of oxygen-enriched gas collection cavities in the fresh-keeping spaces with gas adjustment requirements according to the gas adjustment requirement conditions of the plurality of fresh-keeping spaces, and closing the pipes from the sucking pump to the oxygen-enriched gas collection cavities in the fresh-keeping spaces without the gas adjustment requirements; and controlling the sucking pump to operate to discharge gases in the oxygen-enriched gas collection cavities in the fresh-keeping spaces with gas adjustment requirements. According to the solution of the invention, the gas adjustment is achieved for the plurality of fresh-keeping spaces in a storage space by using one sucking pump; different gas adjustments can be achieved for different types of articles stored in different fresh-keeping spaces; and the fresh-keeping requirements of different types of articles are fully met.

Description

technical field [0001] The invention relates to the field of item storage, in particular to an air conditioning control method for a refrigerating and freezing device and the refrigerating 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 l...
