Partial-freezing meat fresh-preservation control method, controller, and refrigerator

Abstract

A partial-freezing meat fresh-preservation control method, a controller and a refrigerator are provided. The control method includes: S1 (), acquiring a current temperature of meat food in a compartment of a refrigerator in real time; S2 (), judging whether the current temperature of the meat food is greater than or equal to a first temperature threshold t, and if yes, performing S3 (); S3 (), controlling the compartment to perform a cooling operation; S4 (), judging whether the meat food is frozen during the cooling operation, and if yes, performing S5 (), S5 (), starting timing once the freezing occurs, and performing S6 () after the timing reaches a first preset time period; S6 (), controlling the compartment to perform a heating operation; wherein, after the performance of the step S6 () is completed, the performance of the step S1 () is continued. The partial-freezing fresh-preservation control method provided by the embodiment of the present disclosure can maintain the meat food in a fresh and easy-to-cut state for a long time, and make up for the technical gap in the field.
