Sealing structure for refrigerator

Abstract

A sealing structure for a refrigerator comprises a blocking member provided inside an air dam having a predetermined width between a refrigerator cabinet and a door liner of a door, for preventing convection in the air dam, so that convection in the air dam is prevented and thus external heat is prevented from being introduced into a storage compartment through the air dam.

1 . A sealing structure for a refrigerator, comprising a convection preventing device provided inside an air dam having a predetermined width between a refrigerator cabinet and a door liner of a door, for preventing convection in the air dam.  
   
   
       2 . The structure of  claim 1 , wherein the convection preventing device comprises at least one blocking member formed in a plate shape, for blocking between the door liner and the cabinet.  
   
   
       3 . The structure of  claim 2 , wherein the blocking member is fixed to the door liner, is extended toward the cabinet, and is elongated in a longitudinal direction of the door.  
   
   
       4 . The structure of  claim 2 , wherein cut-off grooves are formed on the blocking member at predetermined intervals in a longitudinal direction of the blocking member.  
   
   
       5 . The structure of  claim 2 , wherein the blocking member has a width which is substantially similar to or larger than a width between the door liner and the cabinet.  
   
   
       6 . The structure of  claim 5 , wherein the blocking member is formed to have a width enough that an end of the blocking member can be in contact with the door liner when the door is closed.  
   
   
       7 . The structure of  claim 5 , wherein the blocking member is curved at a predetermined curvature.  
   
   
       8 . The structure of  claim 7 , wherein the blocking member is curved in an opposite direction to a direction that the door is closed.  
   
   
       9 . The structure of  claim 7 , wherein a plurality of the blocking members are curved in the same direction.  
   
   
       10 . The structure of  claim 2 , wherein a thickness of the blocking member becomes thinner toward an end in a width direction thereof.  
   
   
       11 . The structure of  claim 2 , wherein a plurality of the blocking members are installed at intervals of about 5 mm to 10 mm.  
   
   
       12 . The structure of  claim 2 , wherein the blocking member is extended with being curved plural times along a longitudinal direction of the door.  
   
   
       13 . The structure of  claim 12 , wherein a concave portion and a convex portion of the blocking member which are formed by curving the blocking member are disposed at regular intervals.  
   
   
       14 . The structure of  claim 13 , wherein the concave portion and the convex portion of the blocking member have the same curvature.  
   
   
       15 . The structure of  claim 12 , wherein cut-off grooves are formed on the blocking member at regular intervals.  
   
   
       16 . The structure of  claim 2 , wherein the convection preventing device comprises a supporting portion formed as a plate shape which is substantially parallel to the surface of the door liner and closely attached to the surface of the door liner; and a fixing portion protruding from the supporting portion and inserted in a fixing groove recessed in the door liner, and the blocking member is extended from the flat panel portion toward the cabinet.
