Cool air supplying apparatus and refrigerator having the same

Abstract

A cool air supplying apparatus for a refrigerator is disclosed. The cool air supplying apparatus includes a freezing chamber evaporator that generates cool air supplied to a freezing chamber, a refrigerating chamber evaporator that generates cool air supplied to a refrigerating chamber, a freezing chamber cross flow fan that blows cool air generated by the freezing chamber evaporator toward the freezing chamber, a refrigerating chamber cross flow fan that blows cool air generated by the refrigerating chamber evaporator, and a driving motor that drives the freezing chamber cross flow fan and the refrigerating chamber cross flow fan. With this structure, cool air introduced in the evaporators is substantially uniform, thus enhancing heat exchanging efficiency.

       5 . The apparatus of  claim 1 , wherein a width of the refrigerating chamber cross flow fan is equal to that of the refrigerating chamber evaporator. 
   
   
       6 . The apparatus of  claim 1 , wherein the at least one driving motor is installed within a separation wall that separates the freezing chamber and the refrigerating chamber. 
   
   
       7 . The apparatus of  claim 1 , wherein the at least one driving motor is an outer rotor type motor. 
   
   
       8 . The apparatus of  claim 1 , further comprising:
 a guide that receives the cross flow fan; and   at least one duct connected with the guide that provides cool air.   
   
   
       9 . The apparatus of  claim 8 , wherein the at least one duct comprises a plurality of ducts installed along side corners of the respective freezing chamber or refrigerating chamber. 
   
   
       10 . A refrigerator comprising the cool air supplying apparatus of  claim 1 . 
   
   
       11 . A refrigerator, comprising:
 a freezing chamber;   a refrigerating chamber separated by a separation wall from the freezing chamber;   a freezing chamber evaporator that generates cool air to be supplied to the freezing chamber;   a refrigerating chamber evaporator that generates cool air to be supplied to the refrigerating chamber;   a freezing chamber cross flow fan that blows cool air generated by the freezing chamber evaporator toward the freezing chamber;   a refrigerating chamber cross flow fan that blows cool air generated by the refrigerating chamber evaporator; and   at least one driving motor that drives the freezing chamber cross flow fan and the refrigerating chamber cross flow fan.   
   
   
       12 . The refrigerator of  claim 11 , wherein the at least one driving motor comprises a single driving motor that simultaneously drives the freezing chamber cross flow fan and the refrigerating chamber cross flow fan. 
   
   
       13 . The refrigerator of  claim 11 , wherein the at least one driving motor comprises a pair of driving motors that separately drive the freezing chamber cross flow fan and the refrigerating chamber cross flow fan, respectively. 
   
   
       14 . The refrigerator of  claim 11 , wherein a width of the freezing chamber cross flow fan is equal to that of the freezing chamber evaporator. 
   
   
       15 . The refrigerator of  claim 11 , wherein a width of the refrigerating chamber cross flow fan is equal to that of the refrigerating chamber evaporator. 
   
   
       16 . The refrigerator of  claim 11 , wherein the at least one driving motor is installed within a separation wall that separates the freezing chamber and the refrigerating chamber. 
   
   
       17 . The refrigerator of  claim 11 , wherein the at least one driving motor is an outer rotor type motor. 
   
   
       18 . The refrigerator of  claim 11 , further comprising:
 a guide that receives the cross flow fan; and   duct at least one connected with the guide that provides cool air.   
   
   
       19 . The refrigerator of  claim 11 , wherein the at least one duct comprises a plurality of ducts installed along side corners of the respective freezing chamber or refrigerating chamber.
