Refrigerator

Abstract

Provided is a refrigerator. The refrigerator includes a cabinet in which a refrigerator compartment and a freezer compartment are defined, a refrigerator compartment door opening and closing the refrigerator compartment, an ice making chamber defined in the refrigerator compartment door, the ice making chamber providing an ice making space, a cool air duct guiding a flow of cool air toward the ice making chamber, a duct deco disposed on an inner sidewall of the ice making chamber or the refrigerator compartment, the duct deco being disposed at each of positions corresponding to a cool air outlet port and a cool air inlet port of the cool air duct communicating with the ice making chamber, and a gasket disposed on the inner sidewall of the ice making chamber or the refrigerator compartment, the gasket being closely attached to the duct deco when the refrigerator compartment door is closed to prevent the cool air from leaking. The gasket has an inner diameter greater than that of the duct deco.

         7 . The refrigerator according to  claim 6 , wherein the mounting part is disposed at a position corresponding to an opening of the cool air duct. 
     
     
         8 . The refrigerator according to  claim 6 , wherein a fixing part coupled to a side of the mounting part to fix the duct deco is disposed on the duct deco. 
     
     
         9 . The refrigerator according to  claim 1 , wherein the cool air duct is buried by an insulation material within the cabinet. 
     
     
         10 . A refrigerator comprising:
 a refrigerator compartment door opening and closing a refrigerator compartment;   an ice making chamber defined in the refrigerator compartment door, the ice making chamber providing an ice making space;   a cool air duct disposed in the refrigerator compartment to provide a cool air flow path between the ice making chamber and an evaporator;   a duct deco disposed in a sidewall of the refrigerator compartment corresponding to a cool air outlet port and a cool air inlet port of the cool air duct to provide a cool air path;   a gasket disposed on each of a cool air intake hole and a cool air discharge hole opened to the ice making chamber to prevent the cool air from leaking when the refrigerator compartment door is closed; and   a heater disposed around the duct deco to generate heat,   wherein the gasket has an inner diameter greater than that of the duct deco.   
     
     
         11 . The refrigerator according to  claim 10 , wherein the heater is disposed on a back surface of an inner case defining an inner surface of the refrigerator compartment. 
     
     
         12 . The refrigerator according to  claim 11 , wherein a heat transfer member transferring heat generated by the heater is disposed on the back surface of the inner case. 
     
     
         13 . The refrigerator according to  claim 12 , wherein the heat transfer member is disposed on the back surface of the inner case corresponding to a portion contacting the gasket. 
     
     
         14 . The refrigerator according to  claim 12 , wherein the heat transfer member is disposed at a position adjacent to the duct deco. 
     
     
         15 . The refrigerator according to  claim 12 , wherein the heat transfer member is disposed on the inner case corresponding to each of circumferences of the inlet and outlet ports of the cool air duct. 
     
     
         16 . The refrigerator according to  claim 11 , wherein the heater is disposed on the inner case corresponding to the gasket when the refrigerator compartment door is closed.
