Cool air supply structure for refrigerator

Abstract

The present invention discloses a cool air supply structure for a refrigerator, including an inner casing defining a storage space in the refrigerator, a cool air discharge hole formed at the inner casing, and a passage member provided at the rear face of the inner casing, for forming a cool air passage and communicating with the cool air discharge hole, or including a passage provided at a rear face of an inner casing defining a storage space in the refrigerator, the cool air to be supplied to the storage space flowing in the passage, and at least one cool air discharge hole formed at the front face of the inner casing, and operated as an outlet for discharging the cool air flowing in the passage. As a result, the flow of the cool air can be facilitated by the simple configuration.

1 . A cool air supply structure for a refrigerator, comprising:
 an inner casing defining a storage space in the refrigerator;   a cool air discharge hole formed at the inner casing; and   a passage member provided at the rear face of the inner casing, for forming a cool air passage and communicating with the cool air discharge hole.   
   
   
       2 . The cool air supply structure of  claim 1 , wherein a part of the inner casing forms a long passage groove protruding to the storage space, and the passage member is provided inside the passage groove at the rear face of the inner casing. 
   
   
       3 . The cool air supply structure of  claim 2 , wherein the long passage groove is formed in a pair to be spaced apart from each other at a predetermined interval. 
   
   
       4 . The cool air supply structure of  claim 1 , wherein the passage member makes the passage communicate with the cool air discharge hole, and shields the passage from a foaming space wherein the rear face of the inner casing forms a part of the boundary. 
   
   
       5 . The cool air supply structure of  claim 4 , wherein the passage member comprises a first member and a second member, the first member makes the passage communicate with the cool air discharge hole, and opens a part of the passage toward the foaming space, and the second member shields the part of the passage open to the foaming space from the foaming space. 
   
   
       6 . The cool air supply structure of  claim 5 , wherein the first member comprises a discharge opening communicating with the cool air discharge hole.  
   
   
       7 . The cool air supply structure of  claim 5 , wherein one face of the first member is closely adhered to the rear face of the inner casing, and the other face of the first member is closely adhered to the second member, for forming the passage between the first member and the second member. 
   
   
       8 . The cool air supply structure of  claim 7 , wherein at least one seating protrusion and seating recess matching in shape with each other are provided at the closely-adhered faces of the first and second members, respectively. 
   
   
       9 . A cool air supply structure for a refrigerator, comprising:
 a passage provided at a rear face of an inner casing defining a storage space in the refrigerator, the cool air to be supplied to the storage space flowing in the passage; and   at least one cool air discharge hole formed at the front face of the inner casing, and operated as an outlet for discharging the cool air flowing in the passage.   
   
   
       10 . The cool air supply structure of  claim 9 , wherein a part of the inner casing forms a long passage groove protruding to the storage space, and the passage is provided inside the passage groove at the rear face of the inner casing. 
   
   
       11 . The cool air supply structure of  claim 10 , wherein the long passage groove is formed in a pair to be spaced apart from each other at a predetermined interval. 
   
   
       12 . The cool air supply structure of  claim 9 , wherein the passage is formed by a separate insulation member. 
   
   
       13 . The cool air supply structure of  claim 12 , wherein the insulation member makes the passage communicate with the cool air discharge hole, and shields the passage from a foaming space wherein the rear face of the inner casing forms a part of the boundary. 
   
   
       14 . The cool air supply structure of  claim 13 , wherein the insulation member comprises a first member and a second member, the first member makes the passage communicate with the cool air discharge hole, and opens a part of the passage toward the foaming space, and the second member shields the part of the passage open to the foaming space from the foaming space. 
   
   
       15 . The cool air supply structure of  claim 14 , wherein the first member comprises a discharge opening communicating with the cool air discharge hole. 
   
   
       16 . The cool air supply structure of  claim 14 , wherein one face of the first member is closely adhered to the rear face of the inner casing, and the other face of the first member is closely adhered to the second member, for forming the passage between the first member and the second member. 
   
   
       17 . The cool air supply structure of  claim 16 , wherein at least one seating protrusion and seating recess matching in shape with each other are provided at the closely-adhered faces of the first and second members, respectively.
