PARTITIONED-COOLING CONTROL METHOD AND PARTITIONED-COOLING CONTROL DEVICE FOR REFRIGERATED COMPARTMENT OF REFRIGERATOR

摘要

Provided are a partitioned-cooling control method and partitioned-cooling control device for the refrigerated compartment of a refrigerator. The refrigerated compartment of the refrigerator is divided into a plurality of storage spaces (140). The refrigerated compartment is internally provided with an infrared sensing device (130) and a branching air supply device (220). The partitioned-cooling control method comprises: determining that the refrigerated compartment has entered a cooling state; obtaining the temperatures, sensed by the infrared device (130), of items stored inside the plurality of storage spaces; comparing the temperature of the items in each of the storage spaces to the preset temperature threshold value for activation of zone cooling of each of the storage spaces; setting to activated the cooling state identifier corresponding to the storage space having items at a temperature greater than the zone cooling activation-temperature threshold value; driving the branching air supply device (220) to run in a state in which it provides a cooled air flow to the storage space having an activated cooling state identifier. The solution prevents the wastage of electricity and improves the storage performance of the refrigerated compartment, reducing the loss of nutrition from foods.
