Abstract

The invention provides a cold storage and freezing device. The cold storage and freezing device comprises a first storage chamber which is divided into at least two storage spaces; a cooling chamber;an air path system, wherein the air path system is provided with at least two air supply ports, at least two first air return ports and an on-off control device, each air supply port communicates withthe cooling chamber and one storage space, and each first air return port communicates with one storage space and the cooling chamber; and the on-off control device controls airflow from the coolingchamber to flow to one or more of the at least two air supply ports, and then all or part of the airflow is controlled to flow to the corresponding storage space; and a gear generation device, whereinthe gear generation device is configured to generate at least two gear instruction groups, and each gear instruction group comprises a plurality of gear instructions correspondingly controlling one storage space; and each gear instruction comprises control information enabling the corresponding storage space to be at a target temperature, so that the cold storage and freezing device controls theon-off control device according to each gear instruction, and then the temperature in the corresponding storage space is controlled.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigeration and freezing device. Background technique [0002] With the development of social economy and the improvement of people's living standards, refrigerators have also become an indispensable household appliance in people's daily life. Existing refrigerators have a uniform temperature control for the refrigerated compartments, each layer is set at a uniform temperature of 0-5°C, and the best storage temperature for all foods is different. If the user sets the temperature to the low range of 0°C, the temperature of the entire compartment of the refrigerator will be around 0°C. Food stored at an optimal temperature greater than 5°C will greatly shorten the food preservation period and accelerate food deterioration. Contents of the invention [0003] In view of the above-mentioned problems, an invention has been proposed to provide a refrigerating and...
