Opening and closing device for refrigerator door

Abstract

A refrigerator door opening and closing device, comprising: a pair of doors for opening and closing a single storage space on a refrigerator body; a fixed hinge installed on any one of the pair of doors; a movable hinge installed on the other door of the pair of doors , wherein, a pair of doors can be opened and closed separately with the fixed hinge and the movable hinge as the axis, and can also be opened simultaneously with the fixed hinge as the axis. The pair of doors includes: a left door which can selectively open and close the left part of the storage space; and a right door which can selectively open and close the right part of the storage space. The present invention can open two doors in one storage space. Only one door is opened when taking and placing small storage objects, which prevents cold air from leaking out. This reduces the opening area by 1 / 2 compared with the simultaneous opening of two doors, reduces the leakage of air-conditioning, and effectively reduces the power consumption of the automatic. In the present invention, there is a connecting piece that combines the two doors, and the two doors can be opened simultaneously as required. When taking and placing relatively large food, the trouble of opening two doors respectively is eliminated, and the convenience of using the refrigerator is improved.

Description

Technical field [0001] The invention relates to a refrigerator. In particular, it relates to an opening and closing device that can open and close the refrigerator doors of the refrigerator door individually or at the same time in a refrigerator having two or more doors. Background technique [0002] Generally speaking, refrigerators are divided into freezer compartments for keeping ice containers and frozen foods at selected temperatures and refrigerating compartments for storing refrigerated items. There is a refrigeration cycle device inside, followed by compression, condensation, expansion, evaporation, and freezing cycles. In this cycle, the external heat of the evaporator is absorbed to maintain the internal freezing and refrigeration state. [0003] figure 1 It is a schematic diagram of the appearance of a general refrigerator. [0004] As shown in the figure, the inside of the rectangular parallelepiped refrigerator body 10 forms a freezing compartment (not shown) and a...

AI Technical Summary

Problems solved by technology

[0008] That is to say, since the refrigerating chamber has only one refrigerating door 14, the refrigerating chamber door 14 must be opened as a whole when placing or taking out the stored items kept in the refrigerating chamber, so there is a problem of cold air leakage in the refrigerating chamber.
