Abstract: A hinge assembly of a box device includes a first sliding rail and a second sliding rail. The first sliding rail extends in a straight line, and the second sliding rail extends along an ellipse. When a door body blocks an opening, the first sliding rail is perpendicular to a plane where the opening is located, and the portion of the second sliding rail that is away from a box body is close to a pivoting side with respect to the first sliding rail, and the door body moves towards a target side of the box body during opening of the door body, with respect to the box body, from a state of blocking the opening, to reduce the extent to which the door body exceeds an outer sidewall of the box body.

Abstract: A refrigerator calibration method and system, and a refrigeration device is described. According to some embodiments of the refrigerator calibration method, by means of the variation in the temperatures of a plurality of compartments after any one refrigeration system operates for a predetermined time, a correlation between the refrigeration system and a compartment can be determined, such that a connection between the refrigeration system and the compartment does not need to be pre-specified. Therefore, a refrigerator being unable to perform normal refrigeration due to a connection error during a production process can be effectively avoided, and the probability of needing to repair the refrigerator is reduced, thereby improving the production efficiency of the refrigerator and the reliability of the refrigerator.

Abstract: Disclosed are a refrigerator cooling system and a method for defrosting a refrigerator. The refrigerator cooling system includes a refrigerant circulation flow path provided with a compressor, a condenser, a throttling device and an evaporator. The evaporator includes a heat exchange core tube including a main inlet, a main outlet and at least one middle inlet. The refrigerant circulation flow path includes a first flow path section. The defrosting branch is connected among the exhaust port of the compressor, the main inlet and the middle inlet. The switching device is for switching the defrosting branch to communicate the exhaust port of the compressor with at least one of the main inlet and the middle inlet, and is further for switching the first flow path section to be communicated. When the exhaust port of the compressor communicates with the main inlet, the entire heat exchange core tube is defrosted, and when the exhaust port of the compressor communicates with the middle inlet, the heat exchange core tube is defrosted in part.
