Door hinge of embedded refrigerator and embedded refrigerator

Abstract

The invention discloses a door hinge of an embedded refrigerator and the embedded refrigerator, and relates to the technical field of refrigeration equipment. The door hinge of the embedded refrigerator and the embedded refrigerator are designed in order to resolve the problems that an existing door hinge of the embedded refrigerator is large in size, large in installation size and the like. The door hinge of the embedded refrigerator comprises a fixed hinge seat, a movable hinge seat, a long swinging rod, a first short swinging rod, a second short swinging rod and a third short swinging rod, wherein one end of the long swinging rod is hinged to the fixed hinge seat, one end of the first short swinging rod and one end of the second short swinging rod are hinged to the long swinging rod, the other end of the first short swinging rod and the other end of the second short swinging rod are hinged to the movable hinge seat, one end of the third short swinging rod is hinged to the fixed hinge seat, and the other end of the third short swinging rod is hinged to the second short swinging rod. The invention further provides the embedded refrigerator with the door hinge. The fixed hinge seat, the movable hinge seat, the long swinging rod and the three short swinging rods of the door hinge of the embedded refrigerator form a six-connecting-rod mechanism, opening and closing of the door of the embedded refrigerator are achieved, and the occupied space and the installation size of the door hinge of the embedded refrigerator are reduced.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to an embedded refrigerator door hinge and an embedded refrigerator. Background technique [0002] The built-in refrigerator is an electrical product placed in the cabinet. By opening the cabinet door, the refrigerator door is directly driven to open, which saves space and has a fashionable appearance. It has become a trend in the refrigerator industry. [0003] The existing embedded refrigerator door hinges mostly use four-bar linkage, which has the following disadvantages: [0004] 1. The volume of the door hinge is too large, which affects the volume and aesthetics of the refrigerator; [0005] 2. The installation size of the fastening screws of the door hinge fixing hinge seat is large, which affects the volume and aesthetics of the refrigerator; [0006] 3. Since most of the main structure is made of sheet metal, the rigidity of the door hinge is relatively we...

AI Technical Summary

Problems solved by technology

[0004] 1. The door hinge is too large, which affects the volume and aesthetics of the refrigerator;

[0005] 2. The installation size of the fastening screws for fixing the hinge seat of the door hinge is relatively large, which affects the volume and aesthetics of the refrigerator;

[0006] 3. Since most of the main structure is processed by sheet metal, the rigidity of the door hinge is relatively weak in some positions;

[0007] 4. The door hinge opening and closing door assist mechanism occupies a large space, and the stability of the structure is not high;

[0008] 5. In a special decoration environment, the door opening angle of the built-in refrigerator door may not reach the maximum design angle, which will cause the door to hit the door
