Abstract

Official abstract text for this publication.

The present invention discloses a refrigerator, including a cabinet, a door for opening and closing the cabinet, and a hinge assembly for connecting the cabinet and the door, wherein the cabinet includes an accommodating chamber and an outer side surface adjacent to the hinge assembly and located on an extension section of a rotation path of the door, a direction from the accommodating chamber towards the outer side surface serves as a first direction, and when the door is in an opening process, the hinge assembly drives the door to move away from the cabinet in the first direction. In the present invention, the door may be driven to move away from the cabinet in the first direction by the hinge assembly; that is, the door moves away from the accommodating chamber, thus guaranteeing an opening degree of the cabinet.
