Refrigerator and filler thereof

Abstract

A filler to seal a gap between a plurality of doors is provided with a height adjustment portion, thereby enabling a height of the filler to be uniformly maintained regardless of deflection of the door. Accordingly, the filler may be smoothly operated regardless of deflection of the door, and cold air in a storage chamber may be prevented from escaping. The height adjustment portion has a truncated cone shape, and may be supported by a bottom surface of the storage chamber when the door is closed in a deflected state.

What is claimed is: 
     
         1 . A refrigerator comprising:
 a main body;   a storage chamber defined within the main body;   a first door which is rotatably coupled to one side portion of the main body so as to open and close a portion of the storage chamber;   a second door which is rotatably coupled to the other side portion of the main body so as to open and close a remaining portion of the storage chamber; and   a filler which is rotatably arranged at the first door so as to seal a gap between the first and second doors in a state of closing the first and second doors, and has a guide protrusion inserted into a guide groove provided at the main body to move along the guide groove;   wherein the filler comprises a height adjustment portion which increases a height of the filler so that the guide protrusion is able to be inserted into the guide groove when the first door is closed in a deflected state.   
     
     
         2 . The refrigerator according to  claim 1 , wherein the height adjustment portion is a protrusion which protrudes from a lower end portion of the filler. 
     
     
         3 . The refrigerator according to  claim 1 , wherein, when the first door is closed in the deflected state, the height adjustment portion comes into contact with a bottom surface of the storage chamber to thereby allow the height of the filler to be increased. 
     
     
         4 . The refrigerator according to  claim 1 , wherein, when the first door is closed in a non-deflected state, the height adjustment portion does not come into contact with a bottom surface of the storage chamber. 
     
     
         5 . The refrigerator according to  claim 1 , wherein the height adjustment portion has a truncated cone shape. 
     
     
         6 . The refrigerator according to  claim 5 , wherein the height adjustment portion comprises a flat surface at a center thereof, and an inclined surface formed around the flat surface. 
     
     
         7 . The refrigerator according to  claim 1 , wherein:
 the filler comprises a heat insulator and a case receiving the heat insulator; and   the height adjustment portion is integrated with the case.   
     
     
         8 . The refrigerator according to  claim 7 , wherein the height adjustment portion is injection-molded with a resin material together with the case. 
     
     
         9 . A refrigerator comprising:
 a main body;   a storage chamber defined within the main body;   a first door which is rotatably coupled to one side portion of the main body so as to open and close a portion of the storage chamber;   a second door which is rotatably coupled to the other side portion of the main body so as to open and close a remaining portion of the storage chamber;   a filler which is rotatably arranged at the first door so as to seal a gap between the first and second doors in a state of closing the first and second doors; and   a height adjustment portion which protrudes from a lower end portion of the filler so as to be arranged between the filler and a bottom surface of the storage chamber in a state of closing the first door.   
     
     
         10 . The refrigerator according to  claim 9 , wherein, when the first door is closed in a deflected state, the height adjustment portion comes into contact with the bottom surface of the storage chamber to thereby allow a height of the filler to be increased. 
     
     
         11 . A filler which is rotatably coupled to any one of a plurality of doors so as to seal a gap between the plurality of doors, the filler comprising:
 a guide protrusion which is inserted into a guide groove provided at a main body to move along the guide groove; and   a height adjustment portion which protrudes from a lower end portion of the filler so as to come into contact with a bottom surface of a storage chamber when the door coupled with the filler is closed in a deflected state.   
     
     
         12 . The filler according to  claim 11 , wherein the height adjustment portion has a truncated cone shape. 
     
     
         13 . The filler according to  claim 12 , wherein the height adjustment portion comprises a flat surface at a center thereof, and an inclined surface formed around the flat surface. 
     
     
         14 . The filler according to  claim 11 , wherein:
 the filler comprises a heat insulator and a case receiving the heat insulator; and   the height adjustment portion is integrated with the case.   
     
     
         15 . The filler according to  claim 14 , wherein the height adjustment portion is injection-molded with a resin material together with the case.
