Partition refrigeration control method and device for refrigerating chamber of refrigerator

A partition refrigeration control device for a refrigerating chamber of a refrigerator, wherein the refrigerating chamber is divided into a plurality of item storage compartments;

• an infrared sensor for sensing temperatures of items stored in the item storage compartments respectively is arranged in the refrigerating chamber;
• the refrigerator is provided with an air blowing splitter configured to distribute a cooling air flow from a cold source to the plurality of item storage compartments;
• and the partition refrigeration control device comprises:
• a state determination module configured to determine that the refrigerating chamber enters a refrigeration state;
• a first temperature acquisition module configured to acquire the temperatures, sensed by the infrared sensor, of the items stored in the plurality of item storage compartments;
• a first comparison module configured to compare the temperature of the items stored in each item storage compartment with a corresponding preset area refrigeration start temperature threshold of each item storage compartment;
• an identifier setting module configured to set a refrigeration state identifier corresponding to the item storage compartment in which the temperature of the item is higher than the corresponding area refrigeration start temperature threshold as start;
• and
• a driving module configured to drive the air blowing splitter to operate in a state of providing the cooling air flow to the item storage compartment whose refrigeration state identifier is start.
