Refrigerator

Abstract

A refrigerator includes a body, a first door rotatably coupled to one side of the body, and a second door rotatably coupled to the other side of the body. Both the first door and the second door having pocket portions disposed at rear sides of the doors so as to store food. A first upper hinge and a first lower hinge rotatably support the first door and a second upper hinge and a second lower hinge rotatably support the second door and a strength of the first lower hinge and a strength of the second lower hinge are different from each other.

What is claimed is: 
     
         1 . A refrigerator comprising:
 a body;   a first door rotatably coupled to one side of the body and having a first pocket portion disposed at a rear side of the first door so as to store food;   a second door rotatably coupled to the other side of the body and having a second pocket portion disposed at a rear side of the second door so as to store food;   a first upper hinge and a first lower hinge coupled to an upper part and a lower part of the first door so as to rotatably support the first door; and   a second upper hinge and a second lower hinge coupled to an upper part and a lower part of the second door so as to rotatably support the second door,   wherein the first lower hinge has a predetermined strength that resists deformation caused by a load of the first door and a load of the food stored in the first pocket portion, and   the second lower hinge has a predetermined strength that resists deformation caused by a load of the second door and a load of the food stored in the second pocket portion, and   the strength of the first lower hinge and the strength of the second lower hinge are different from each other.   
     
     
         2 . The refrigerator of  claim 1 , wherein a storage capacity of the first pocket portion is smaller than a storage capacity of the second pocket portion, and
 the strength of the first lower hinge is smaller than the strength of the second lower hinge.   
     
     
         3 . The refrigerator of  claim 1 , wherein shapes of the first lower hinge and the second lower hinge are asymmetrical. 
     
     
         4 . The refrigerator of  claim 1 , wherein each of the first lower hinge and the second lower hinge comprises a fixing portion coupled to the body and an extension portion, which extends from the fixing portion and from which a door rotation shaft protrudes, and
 a thickness of the fixing portion of the first lower hinge and a thickness of the fixing portion of the second lower hinge are different from each other.   
     
     
         5 . The refrigerator of  claim 1 , wherein each of the first lower hinge and the second lower hinge comprises a fixing portion coupled to the body and an extension portion, which extends from the fixing portion and from which a door rotation shaft protrudes, and
 one of the first lower hinge and the second lower hinge further comprises a fillet portion disposed to reinforce connection strength of the fixing portion and the extension portion.   
     
     
         6 . The refrigerator of  claim 1 , wherein a material used to form the first lower hinge and a material used to form the second lower hinge are different from each other. 
     
     
         7 . The refrigerator of  claim 6 , wherein a material used to form one of the first lower hinge and the second lower hinge is a zinc alloy, and
 a material used to form the other one of the first lower hinge and the second lower hinge is an aluminum alloy.   
     
     
         8 . A refrigerator comprising:
 a body;   an upper, first storage compartment and a lower, second storage compartment provided inside the body;   a first door and a second door rotatably coupled to the body so as to open/close the first storage compartment and the second storage compartment;   a first upper hinge and a first lower hinge coupled to an upper part and a lower part of the first door so as to rotatably support the first door;   a second lower hinge coupled to a lower part of the second door so as to rotatably support the second door;   a support shaft that perforates the second door and is vertically provided under the first lower hinge so as to support the first lower hinge; and   a support leg coupled to a bottom end of the support shaft and supported on a ground.   
     
     
         9 . The refrigerator of  claim 8 , wherein the first lower hinge comprises an insertion groove into which a top end of the support shaft is inserted and is coupled. 
     
     
         10 . The refrigerator of  claim 8 , wherein the second door comprises a through hole through which the support shaft passes. 
     
     
         11 . The refrigerator of  claim 8 , wherein the second door rotates around the support shaft. 
     
     
         12 . The refrigerator of  claim 8 , wherein the support shaft perforates the second lower hinge. 
     
     
         13 . The refrigerator of  claim 8 , wherein the support shaft is formed integrally with the second lower hinge. 
     
     
         14 . The refrigerator of  claim 8 , wherein the support shaft comprises a female screw portion through which the support shaft is coupled to the support leg, and
 the support leg comprises a male screw portion screw-coupled to the female screw portion.   
     
     
         15 . The refrigerator of  claim 8 , wherein the first storage compartment is partitioned off from the second storage compartment. 
     
     
         16 . A refrigerator comprising:
 a body;   a first door coupled to the body by way of at least one first hinge; and   a second door coupled to the body by way of at least one second hinge,   wherein a max load strength of the at least one first hinge is greater than a max load strength of the at least one second hinge.
