Title: PARTIAL-FREEZING MEAT FRESH-PRESERVATION CONTROL METHOD, CONTROLLER, AND REFRIGERATOR
Abstract:
Provided are a partial-freezing meat fresh-preservation control method, a controller, and a refrigerator. The control method comprises: S1(101), acquiring a current temperature of meat food in a refrigerator compartment in real time; S2(102), determining whether the current temperature of the meat food is higher than or equal to a first temperature threshold t0, and if yes, performing steps S3(103); S3(103), controlling the compartment to perform a cooling operation; S4(104), determining whether the meat food is frozen during cooling, and if yes, performing step S5(105); S5(105), starting timing once freezing happens, and performing S6(106) after the timing reaches a first preset time period; S6(106), controlling the compartment to perform a heating operation; and performing step S1(101) after step S5(105) is completed. The partial-freezing meat fresh-preservation control method can preserve meat food in a fresh and easy-to-cut state for a long time.
