Embedded appliance hinge and refrigerator

Abstract

The application provides an embedded household appliance hinge and a refrigerator. The embedded household appliance hinge is installed between a household appliance door body and a household appliance box body, and comprises a hinge body. One end of the hinge body is fixed on the household appliance box body, and the other end is provided with a track frame in the shape of an equilateral triangle. A cam is arranged on the refrigerator door body. The cam comprises two mirror-symmetrical short outer arc edges and two mirror-symmetrical long outer arc edges. The long outer arc edges are tangent to the same side between the two short outer arc edges. During the rotation of the refrigerator door body relative to the refrigerator box body, the outer side wall of the cam moves along the inner side wall of the track frame. During the movement, the outer side wall of the cam keeps three points in contact with and tangent to the inner side wall of the track frame. The refrigerator comprises the household appliance box body and the household appliance door body provided with the hinge. The application has the advantages of simple structure, convenient manufacturing, inward retraction of the household appliance door body when being opened, and effective avoidance of interference between the household appliance door body and other objects in a deep and narrow space or in the deep and narrow space when being opened.
