Refrigerator

Abstract

A refrigerator including a main body with a first storage compartment and a first evaporation compartment provided within the main body in order to cool the first storage compartment. The refrigerator also includes a second storage compartment independently provided in the first storage compartment and maintained at a temperature lower than a temperature of the first storage compartment; and a second evaporation compartment located at a rear side of the second storage compartment to cool the second storage compartment.

What is claimed is: 
     
         1 . A refrigerator, comprising:
 a main body with a first storage compartment;   a first evaporation compartment provided within the main body in order to cool the first storage compartment;   a second storage compartment independently provided in the first storage compartment and maintained at a temperature lower than a temperature of the first storage compartment; and   a second evaporation compartment located at a rear side of the second storage compartment to cool the second storage compartment , the second evaporation compartment including a cold air outlet and a cold air inlet.   
     
     
         2 . The refrigerator of  claim 1 , further comprising:
 a first evaporator disposed in the first evaporation compartment;   a second evaporator disposed in the second evaporation compartment; and   a cooling fan disposed in the first evaporation compartment.   
     
     
         3 . The refrigerator of  claim 2 , wherein the first evaporator and the second evaporator include fin-tube type heat exchangers. 
     
     
         4 . The refrigerator of  claim 2 , wherein the second storage compartment includes:
 a case communicating with the second evaporation compartment and insulated from the first evaporation compartment; and   a drawer including:
 a storage box received in the case and having a cold air hole on a rear side thereof; and 
 a door formed at a front side of the storage box. 
   
     
     
         5 . The refrigerator of  claim 4 , further comprising:
 a main grille to partition the first evaporation compartment and the first storage compartment,   wherein the second evaporation compartment is fixed to a front side of the main grille.   
     
     
         6 . The refrigerator of  claim 5 , wherein the rear side of the case is in contact with a front side of the second evaporation compartment,
 and wherein the second storage compartment and the second evaporation compartment communicate with each other through the cold air inlet and the cold air outlet.   
     
     
         7 . The refrigerator of  claim 5 , wherein the rear side of the case is in contact with the main grille, such that the second evaporation compartment is completely received inside the case. 
     
     
         8 . The refrigerator of  claim 5 , wherein the first storage compartment is a freezing compartment maintained at or below a freezing temperature, and the second storage compartment is a deep freezing compartment maintained at a temperature lower than the temperature in the freezing compartment. 
     
     
         9 . The refrigerator of  claim 1 , wherein the first evaporation compartment is provided at one side of the main body. 
     
     
         10 . The refrigerator of  claim 1 , wherein the first storage compartment includes a freezing compartment. 
     
     
         11 . The refrigerator of  claim 1 , wherein the second storage compartment includes a deep freezing compartment. 
     
     
         12 . The refrigerator of  claim 2 , wherein the first evaporator comprises a main evaporator. 
     
     
         13 . The refrigerator of  claim 2 , wherein the second evaporator comprises a deep evaporator.
