A partition control method for a refrigerator, wherein the refrigerator comprises a door for opening or closing a compartment of the refrigerator, an air supply device for distributing cooling air from a cold source to different positions in the compartment, a camera device for photographing the interior of the compartment, and a control unit for electrically connecting the air supply device and the camera device, wherein the air supply device is provided with a plurality of dampers in the compartment, and the compartment is formed with a plurality of storage partitions corresponding to the dampers; and the partition control method comprises: S1, acquiring an opening/closing state of the door; S2, after receiving opening/closing information about the door, the control unit driving the camera device to obtain a storage-state picture of the interior of the compartment after a closing of the door; S3, retrieving a storage-state picture of the interior of the compartment which was taken prior to opening the door this time, and comparing it with the storage-state picture which was taken after said closing of the door; characterized in that the partition control method further comprises: S4, if items increase in a storage partition of the compartment, enlarging or opening cooling air supply to the storage partition by means of the damper corresponding to the storage partition, and if items decrease in a storage partition of the compartment, reducing or stopping the cooling air supply to the storage partition by means of the damper corresponding to the storage partition, wherein when the air supply device is in a running state, determining whether the average temperature of interior environment of the compartment is less than a preset cooling stop temperature threshold in the compartment; and if so, the air supply device is stopped, wherein the compartment is internally provided with a lighting device for illuminating the interior of the compartment, and after the closing information about the door is acquired in step S2, the lighting device is turned on first, then the camera device is driven to operate, and the lighting device is turned off after the storage-state picture is obtained. S1, acquiring an opening/closing state of the door; S2, after receiving opening/closing information about the door, the control unit driving the camera device to obtain a storage-state picture of the interior of the compartment after a closing of the door; S3, retrieving a storage-state picture of the interior of the compartment which was taken prior to opening the door this time, and comparing it with the storage-state picture which was taken after said closing of the door; S4, if items increase in a storage partition of the compartment, enlarging or opening cooling air supply to the storage partition by means of the damper corresponding to the storage partition, and if items decrease in a storage partition of the compartment, reducing or stopping the cooling air supply to the storage partition by means of the damper corresponding to the storage partition, wherein when the air supply device is in a running state, determining whether the average temperature of interior environment of the compartment is less than a preset cooling stop temperature threshold in the compartment; and if so, the air supply device is stopped, wherein the compartment is internally provided with a lighting device for illuminating the interior of the compartment, and after the closing information about the door is acquired in step S2, the lighting device is turned on first, then the camera device is driven to operate, and the lighting device is turned off after the storage-state picture is obtained.
