Supercooled storage control method, device and equipment for foods in refrigerator and refrigerator system

Abstract

The application relates to a supercooled storage control method, device and equipment for foods in refrigerator and a refrigerator system. The supercooled storage control method comprises the following steps of controlling the temperature of compartments of the refrigerator as a first supercooled temperature, and maintaining for a first preset duration, controlling the temperature of the compartments of the refrigerator as a second supercooled temperature, and maintaining for a second preset duration, controlling a compressor to operate at a maximal permissible rotating speed, maintaining fora third preset duration, maintaining the temperature of the compartments of the refrigerator as the set freezing temperature, enabling the foods to enter a supercooled state by slowly cooling, then controlling the compressor to operate at a maximal permissible rotating speed to enable the refrigerator to be cooled super rapidly, so that the foods pass through a maximal ice crystal growth area rapidly, and tiny ice crystals of uniform sizes are formed in the foods favorably, and at last, maintaining the set freezing temperature to facilitate long-term food storage. In addition, a blowing cooling way is not needed, bad influences of air drying and freezer burn of foods by cold air are avoided, the food quality is ensured, and the food storage effect of the refrigerator is improved.

Description

technical field [0001] The present application relates to the technical field of household electrical appliances, in particular to a method, device, equipment and refrigerator system for controlling the supercooled storage of food in a refrigerator. Background technique [0002] The refrigerator is a kind of refrigeration equipment that maintains a constant low temperature. Since most of the ingredients are not easy to perish at low temperatures and can be stored for a long time, the refrigerator has become a household appliance used by most families to keep fresh ingredients. Bring convenience. When the refrigerator freezes food, many large ice crystals will be formed inside the food, thereby destroying the food cells, and also causing a large amount of blood to flow out after the food is thawed, resulting in the loss of nutrition and poor taste of the food. [0003] The method of freezing food currently used is to utilize the variation of the air volume to control the tem...

AI Technical Summary

Problems solved by technology

[0004] Based on this, it is necessary to provide a method, device, equipment and refrigerator system for controlling the supercooled storage of food in the refrigerator to solve the problem that the traditional method of freezing food causes poor food quality and poor storage effect of the refrigerator.
