Refrigerator

Abstract

The present invention relates to a refrigerator and, in particular, to a refrigerator comprising: a main body comprising an outer case and an inner case which is provided inside the outer case so as to provide an ice making compartment and a refrigerator compartment at the top thereof and provide a freezer compartment at the bottom thereof; an evaporator case which has a cold air discharge port and a cold air suction port in communication with the ice making compartment, and which is provided between the outer case and the inner case; an evaporator installed in the evaporator case so as to supply cold air to the ice making compartment; and a driving unit fan duct assembly installed behind the ice making compartment. The driving unit fan assembly is characterized in that a driving unit assembly, a fan assembly, and a cold air discharge duct are modularized. The driving unit assembly, the fan assembly, and the cold air discharge duct are modularized and provided as one assembly, and thus can be installed in the ice making compartment through a single installation process. In addition; when the fan assembly is installed in a fan accommodation unit, the driving unit assembly and the cold air discharge duct are installed while being disposed at set positions at which the driving unit assembly and the cold air discharge duct are naturally inclined to be installed.

1 . A refrigerator comprising:
 a main body including an outer case and an inner case provided inside the outer case, wherein an upper part of the inner case provides an ice making compartment and a refrigerator compartment, and a lower part of the inner case provides a freezer compartment;   an evaporator case provided between the outer case and the inner case, the evaporator case including a cold air discharge port and a cold air intake port that communicate with the ice making compartment;   an evaporator installed in the evaporator case and configured to supply a cold air to the ice making compartment; and   a driver fan duct assembly installed in a rear part of the ice making compartment,   wherein the driver fan duct assembly is provided by modularizing a driver assembly, a fan assembly, and a cold air discharge duct.   
     
     
         2 . The refrigerator of  claim 1 , wherein the fan assembly is coupled to a rear part of the driver assembly, and the cold air discharge duct is coupled to an upper part of the driver assembly. 
     
     
         3 . The refrigerator of  claim 1 , wherein a first coupling flange is formed on a rear part of the driver assembly,
 wherein a second coupling flange is formed on an upper part of the driver assembly,   wherein a third coupling flange formed on a front part of the fan assembly is fitted and coupled to the first coupling flange so that the third coupling flange is in close contact with the first coupling flange, and   wherein the second coupling flange is fitted and coupled to a fourth coupling flange formed on a lower part of the cold air discharge duct.   
     
     
         4 . The refrigerator of  claim 3 , wherein a first detachable hole is formed in the first coupling flange,
 wherein a first detachable protrusion is formed on the second coupling flange,   wherein a second detachable protrusion formed on the third coupling flange is fitted and coupled to the first detachable hole, and   wherein the second detachable protrusion is fitted and coupled to a second detachable hole formed in the fourth coupling flange.   
     
     
         5 . The refrigerator of  claim 1 , wherein a fan accommodating portion is formed in the evaporator case, and
 wherein as the fan assembly is installed in the fan accommodating portion, the driver assembly and the cold air discharge duct modularized with the fan assembly are disposed at a desired position intended to be installed.   
     
     
         6 . The refrigerator of  claim 1 , wherein the fan assembly includes a fan housing installed in a rear part of the ice making compartment, an impeller rotatably installed inside the fan housing, and a rotation motor rotating the impeller, and
 wherein a cold air intake duct is integrally provided at a front surface of the fan housing, and a cold air exhaust duct is integrally provided at a lower part of the fan housing.   
     
     
         7 . The refrigerator of  claim 6 , wherein a cold air intake passage communicating with the ice making compartment is provided inside the cold air intake duct, and
 wherein a cold air exhaust passage communicating with the cold air intake port is provided inside the cold air exhaust duct.   
     
     
         8 . The refrigerator of  claim 6 , wherein a first sealing member and a second sealing member are attached to a front outer peripheral surface of the fan housing and a lower perimeter surface of the cold air exhaust duct of the fan housing. 
     
     
         9 . The refrigerator of  claim 6 , wherein the fan housing is seated in a fan accommodating portion of the evaporator case,
 wherein a scroll-shaped space is provided in the fan housing, and   wherein the impeller is a centrifugal fan.
