Overcooled meat fresh-preservation control method, controller, and refrigerator

Abstract

An overcooled meat fresh-preservation control method, a controller and a refrigerator are provided. The control method comprises: 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 t0, and if yes, performing step S3 (); S3 (), controlling the compartment to perform a cooling operation; S4 (), judging whether the meat food has been cooled down to a phase transformation point temperature t1 during the cooling operation, and if yes, performing step S5 (), the phase transformation point temperature t1 being the temperature of a critical point at which the phase transformation of the meat food occurs; S5 (), starting timing once the temperature has been cooled down to the phase transformation point temperature t1, and performing step S6 () after the timing reaches a first preset time period; and S6 (), controlling the compartment to perform a low-temperature stable operation according to a third target temperature T, the third target temperature Tbeing a freezing point temperature of the meat food. The overcooled meat fresh-preservation control method provided by the present disclosure may prolong the fresh-preservation period as much as possible while ensuring that the meat food is not frozen.
