Abstract: A refrigerator control method, including: upon acquiring a signal indicating that a person approaches to open a door, controlling a camera to move from an initial position to a first position; upon acquiring a signal indicating that the door switches to an open status, controlling the camera to move to a second position; upon acquiring an opening angle of the door, and controlling the camera to capture an image of an interior of the door when the opening angle is less than a threshold angle; upon acquiring a signal indicating that the door switches to the closed status, controlling the camera to move to the first position and capture an image of an interior of the door; and upon acquiring a signal indicating that the door is closed, controlling the camera to return to the initial position and capture an image of an interior of the refrigerating compartment.

Abstract: A food packaging cup comprises a cup body, an inner film bag disposed in the cup body and a cup lid structure for sealing a cup mouth of the cup body. A bag mouth of the inner film bag is connected with the cup body by a detachable structure, a liquid receiving inner cavity is formed inside the inner film bag, the inner film bag can be separated from the inner wall of the cup body, and an air hole communicated with a gap between the inner film bag and the cup body is formed on the cup body. The food packaging cup is simple in structural production, low in cost, and convenient for various classes of consumers to further drink up thick fruit juice, milk, fermented milk, yoghourt and the like, thereby avoiding residues in the cup. Moreover, garbage of two different materials can be sorted clearly.
