Refrigerator having temperature changing room

Abstract

The present disclosure relates to a refrigerator having a temperature changing room, including a body including a freezer and a separate cold room; doors adapted to open and close the freezer and the cold room; and the temperature changing room in the cold room to maintain a low temperature state to keep an item stored therein fresh, wherein a rear surface of the temperature changing room communicates with a rear surface of an inner case of the body in contact with the temperature changing room, and the temperature changing room has a cool air supplier adapted to supply cool air directly to an interior thereof from an evaporator behind the rear surface of the inner case of the body through a communicating structure thereof.

The invention claimed is: 
     
         1 . A refrigerator comprising:
 a body including a freezer, a separate cold room, and an inner case having a rear surface and a communicating structure;   an evaporator behind the rear surface of the inner case;   doors adapted to open and close the freezer and the cold room; and   a temperature changing room in the cold room, the temperature changing room having a rear surface in communication with the rear surface of an inner case of the body; and   a cool air supplier adapted to supply cool air directly to an interior of the refrigerator from the evaporator through the communicating structure.   
     
     
         2 . The refrigerator according to  claim 1 , wherein the cool air supplier comprises:
 a first through-hole in the rear surface of the temperature changing room;   a second through-hole in the rear surface of the inner case of the body, in communication with the first through-hole; and   a cool air supplying fan adapted to supply the cool air from the evaporator to the second through-hole.   
     
     
         3 . The refrigerator according to  claim 2 , wherein the cool air supplier further comprises a damper in the first through-hole or the second through-hole to control an amount of cool air introduced thereinto, and the cool air supplying fan is between the damper and the evaporator. 
     
     
         4 . The refrigerator according to  claim 3 , wherein the first through-hole extends into the second through-hole and is coupled to an inner peripheral surface of the second through-hole. 
     
     
         5 . The refrigerator according to  claim 3 , wherein the temperature changing room has a temperature sensor therein to check an internal temperature of the temperature changing room in real time, and the temperature sensor is electrically connected to the damper. 
     
     
         6 . The refrigerator according to  claim 1 , further comprising an additional control damper in the body to control a supply of cool air from the evaporator to the cold room or the freezer. 
     
     
         7 . The refrigerator according to  claim 6 , wherein the control damper is above the evaporator and closes a space including the evaporator when a compressor stops operating. 
     
     
         8 . The refrigerator according to  claim 7 , wherein when the compressor operates again, initial cool air generated by the evaporator is first supplied to the temperature changing room. 
     
     
         9 . The refrigerator according to  claim 1 , wherein the temperature changing room is in a lower portion of the body. 
     
     
         10 . The refrigerator according to  claim 2 , further comprising an additional control damper in the body to control a supply of cool air from the evaporator to the cold room or the freezer. 
     
     
         11 . The refrigerator according to  claim 3 , further comprising an additional control damper in the body to control a supply of cool air from the evaporator to the cold room or the freezer. 
     
     
         12 . The refrigerator according to  claim 4 , further comprising an additional control damper in the body to control a supply of cool air from the evaporator to the cold room or the freezer. 
     
     
         13 . The refrigerator according to  claim 5 , further comprising an additional control damper in the body to control a supply of cool air from the evaporator to the cold room or the freezer. 
     
     
         14 . The refrigerator according to  claim 2 , wherein the temperature changing room is in a lower portion of the body. 
     
     
         15 . The refrigerator according to  claim 3 , wherein the temperature changing room is in a lower portion of the body. 
     
     
         16 . The refrigerator according to  claim 4 , wherein the temperature changing room is in a lower portion of the body. 
     
     
         17 . The refrigerator according to  claim 5 , wherein the temperature changing room is in a lower portion of the body.
