Automatic return door hinge and refrigerator using it

Abstract

The invention provides an automatic return door hinge, wherein through the mutual matching of a damping part and a return automatic hinge, when the refrigerator is being closed, the two wedges of a first mounting plate and a second mounting plate are mutually matched to form automatic return, a hollow guide pipe drives a first sleeve to rotate relative to a second sleeve, so as to enable the damping grease between the first and the second sleeves to generate extrusion, as the viscous action of the damping grease blocks the relative motion between the first and the second sleeves to supply the damping buffer action, so that the serious collision between the refrigerator door and the refrigerator body caused by overhigh speed of the automatic closing of the refrigerator door is effectively avoided, and the service life and the using comfort of the refrigerator are effectively improved.

Description

technical field [0001] The invention relates to an automatic return door hinge and a refrigerator using the hinge. Background technique [0002] The refrigerator box and the refrigerator door are connected by hinges so that the refrigerator door can be opened and closed. The general hinge only plays the role of rotating the door. However, in daily life, due to the frequent opening and closing of the refrigerator door, it is inevitable to sometimes forget to close it. The door of the refrigerator, or the closing force is too small, so that the door of the refrigerator is not completely closed, which increases the power consumption of the refrigerator and affects the cooling effect of the refrigerator; The collision of the refrigerator may cause damage to the refrigerator door and refrigerator box, and affect the service life of the refrigerator. [0003] In order to solve the above problems, the existing refrigerator hinge uses a cam assembly to realize automatic return. The...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem in the prior art that when the refrigerator door is automatically closed, the contact collision force and sound between the refrigerator door and the box are too large, which seriously affects the use experience and the life of the refrigerator. A self-returning door hinge with a damping effect, so that the refrigerator door with the hinge is automatically closed within a certain range, avoiding the excessively fast automatic closing speed of the refrigerator door and causing serious collisions between the refrigerator door and the cabinet question
