Description

Refrigerator The present invention relates to a refrigerator. Generally, a refrigerator is a home appliance designed to store food at low temperatures within an internal storage space enclosed by a door. To achieve this, the refrigerator is configured to maintain stored food in optimal conditions by cooling the interior of the storage space using cold air generated through heat exchange with a refrigerant circulating in a freezing cycle. Recent refrigerators are becoming increasingly larger and more multifunctional in line with changes in dietary habits and the trend toward product sophistication, and refrigerators with various structures designed with user convenience in mind are being released. In particular, recently, refrigerators are designed to be embedded in a wall or arranged to harmonize with other furniture or appliances. In this case, the refrigerator requires a certain distance to prevent the corner of the rotating door from interfering with adjacent walls, furniture, or appliances. However, such a spacing not only creates unnecessary space for the placement of the refrigerator but also results in a poor appearance. To solve this problem, refrigerators equipped with multi-link hinges are being developed. However, multi-link refrigerators have the problem of being complex and expensive. In addition, due to the nature of the multi-link operating structure, there are safety issues such as the user's body being trapped between the links, and poor rotational operability of the door.
