Refrigerator, refrigerator control method and refrigerator picture transmission method and system

The invention discloses a refrigerator. The refrigerator comprises a refrigerator body, a refrigerator door and a controller, a plurality of storage chambers are formed in the refrigerator body, and a plurality of camera devices are arranged in the storage chambers; the refrigerator door is arranged at openings of the storage chambers; and the controller is connected with the camera devices and is used for controlling the camera devices to shoot a current picture when detecting that the refrigerator door is closed after being opened, uploading picture information of the current picture to a cloud end and obtaining current time, when the current time is within preset uploading time, a first target picture shot by the camera devices last time before the uploading time is uploaded to the cloud end, so that the cloud end sends the first target picture to the client side when detecting that the client side needs to view the picture, and according to the picture information, the latest picture stored in the client end is obtained and the latest picture is sent to the client end. The invention further discloses a refrigerator control method, a refrigerator picture transmission method and a refrigerator picture transmission system. By adopting the embodiments of the invention, the occupation of cloud storage resources can be effectively avoided, and the flow is saved.
