Duct and refrigerator including same

Abstract

This refrigerator including a main body having a storage chamber, an evaporator provided to generate cold air; and a duct provided to guide the cold air generated by the evaporator to the storage chamber. The duct may comprise a cover, an insulating member, and a fixer to fix the cover and the insulating member. The fixer may comprise a deformation-preventing rib to prevent a part of the cover from being elastically deformed.

1 . A refrigerator comprising:
 a main body including a storage compartment;   an evaporator configured to generate cold air; and   a duct to be provided to guide the cold air generated in the evaporator to the storage compartment,   wherein the duct comprises:
 a cover including:
 a cover body arranged to face the storage compartment; and 
 a cover protrusion including a first protrusion protruding from the cover body; and a second protrusion protruding from the cover body and spaced apart from the first protrusion; 
 
 an insulating member including a receiving hole provided to receive the cover protrusion of the cover; and 
 a fixer, to fix the cover and the insulating member, the fixer including:
 a locking portion couplable to the cover protrusion while the cover protrusion is received in the receiving hole; and 
 
   a deformation preventing rib to be disposed in a gap between the first protrusion and the second protrusion so as to maintain the gap between the first protrusion and the second protrusion while the cover protrusion and the locking portion are coupled to each other.   
     
     
         2 . The refrigerator of  claim 1 , wherein
 the deformation preventing rib is provided to come into contact with at least one of the first protrusion or the second protrusion based on the cover protrusion being pressed along a direction, in which the cover protrusion is separated from the locking portion, while the cover protrusion and the locking portion are coupled to each other.   
     
     
         3 . The refrigerator of  claim 1 , wherein
 the receiving hole comprises:
 a first hole portion; 
 a second hole portion provided on one side of the first hole portion; and 
 a stepped portion formed between the first hole portion and the second hole portion, 
 wherein the fixer further comprises: a pressing rib provided to press the stepped portion within the second hole portion. 
   
     
     
         4 . The refrigerator of  claim 1 , wherein
 the cover protrusion is provided to protrude along a first direction from the cover body,   wherein the fixer is provided to be inserted into the receiving hole in a second direction opposite to the first direction.   
     
     
         5 . The refrigerator of  claim 1 , wherein
 the cover protrusion is provided to be separated from the locking portion as the first protrusion and the second protrusion are pressed to be close to each other while the deformation preventing rib is out from being between the first protrusion and the second protrusion.   
     
     
         6 . The refrigerator of  claim 1 , wherein
 the fixer further comprises:   a fixer body corresponding to the receiving hole; and   an opening formed by penetrating the fixer body,   wherein the cover protrusion comprises:
 a protrusion body extending along a first direction from the cover body; and 
 a protruding portion protruding from the protrusion body along a second direction intersecting the first direction and provided to be locked to the locking portion by passing through the opening. 
   
     
     
         7 . The refrigerator of  claim 6 , wherein
 the protruding portion is provided to be exposed to an outside of the insulating member.   
     
     
         8 . The refrigerator of  claim 6 , wherein
 the protruding portion comprises a groove provided to be gripped.   
     
     
         9 . The refrigerator of  claim 3 , wherein
 the pressing rib has a shape extending along a circumferential direction of the receiving hole.   
     
     
         10 . The refrigerator of  claim 3 , wherein
 the pressing rib is among a plurality of pressing ribs,   wherein the plurality of pressing ribs are spaced apart from each other along a circumferential direction of the receiving hole.   
     
     
         11 . The refrigerator of  claim 3 , wherein
 the pressing rib has a shape extending along a radial direction of the receiving hole.   
     
     
         12 . The refrigerator of  claim 1 , further comprising:
 a fan received in the duct to generate a blowing force,   wherein the fixer further comprises:
 a fixer body corresponding to the receiving hole; and 
 a holder, extending from the fixer body, disposed outside the receiving hole, the holder configured to fix a wire of the fan. 
   
     
     
         13 . The refrigerator of  claim 1 , wherein
 the deformation preventing rib is elastically deformable.   
     
     
         14 . The refrigerator of  claim 1 , wherein
 the storage compartment comprises: a freezing compartment; and a refrigerating compartment disposed below the freezing compartment,   wherein the duct is disposed at a rear side of the freezing compartment.   
     
     
         15 . The refrigerator of  claim 1 , wherein
 the cover of the duct is provided to form a rear surface of at least a portion of the storage compartment.
