The present invention relates to a lower hinge structure of the refrigerator door, and more particularly, to a lower hinge structure of the refrigerator door that can adjust the inclination angle as well as the height of the door by improving the lower hinge structure of the door that opens and closes the refrigerator body. .

In general, the refrigerator is for cooling the air in the refrigerator using a refrigeration cycle so that foods stored therein are stored for a long time without deterioration.

The refrigerator includes a main body forming a storage space separated into a refrigerating compartment and a freezing compartment, and a door mounted on one side of the main body to open and close the freezing compartment and the refrigerating compartment, and a bottom of the main body includes a compressor, a condenser and an evaporator. A refrigeration cycle configured is installed.

That is, in the refrigerator, the low-temperature low-pressure gaseous refrigerant is compressed to high temperature and high pressure, and the compressed high-temperature high-pressure gas phase refrigerant is cooled and condensed while passing through the condenser to be converted into a high-pressure liquid state. As the refrigerant passes through the capillary tube, its temperature and pressure are lowered, and then the evaporator continuously changes to a low-temperature, low-pressure gas state to take heat from the surroundings to cool the air around it.

Thus, the door of the configuration of the refrigerator has a structure in which the upper and lower parts hinged to the side of the refrigerator main body to rotate.

However, when the door hinge is fixed to the side of the main body there is a problem that the cold air of the refrigerator compartment and the freezer compartment of the main body is discharged to the outside when an error occurs in the coupling position.
