Refrigerator

Abstract

A refrigerator comprises: a case having a cooling chamber; a machine room disposed on one side of the case, and configured to accommodate a compressor therein; a condenser disposed on an outer surface of the case; and a heat emission unit configured to guide external air of the case for heat emission of the compressor and the condenser. In the refrigerator, heat emission of the machine room and the condenser is sufficiently performed, and a compact configuration of the machine room is implemented.

1 . A refrigerator, comprising:
 a case having a cooling chamber;   a machine room disposed on one side of the case, and configured to accommodate a compressor therein;   a condenser disposed on an outer surface of the case; and   a heat emission unit configured to guide external air of the case for heat emission of the compressor and the condenser.   
     
     
         2 . The refrigerator of  claim 1 , wherein the machine room is disposed on a rear bottom portion of the case, and the condenser is disposed on a rear surface of the case. 
     
     
         3 . The refrigerator of  claim 2 , wherein the heat emission unit comprises:
 a machine room cover configured to cover the machine room, and having a plurality of first vents;   a condenser case configured to fix the condenser accommodated therein onto a wall surface of the case, having a plurality of second vents, and communicated with one side of the machine room;   a blowing fan configured to generate a flow of air passing through the first and second vents; and   a communication portion configured to communicate an inner side of the machine room with an inner side of the condenser case.   
     
     
         4 . The refrigerator of  claim 3 , wherein the blowing fan is installed such that air introduced into one of the first vents and the second vents is discharged to the other. 
     
     
         5 . The refrigerator of  claim 4 , wherein the fan is coupled to a rear surface of the machine room cover. 
     
     
         6 . The refrigerator of  claim 4 , wherein the fan is installed at an inner side of the communication portion. 
     
     
         7 . The refrigerator of  claim 3 , wherein the blowing fan is implemented as a cross flow fan. 
     
     
         8 . The refrigerator of  claim 3 , wherein the communication portion comprises:
 a communication duct configured to communicate an inner side of the machine room with a rear side of the case; and   a guide duct configured to communicate an inner side of the communication duct with an inner side of the condenser case.   
     
     
         9 . The refrigerator of  claim 8 , wherein the communication duct is formed in a lower middle portion on a rear surface of the case. 
     
     
         10 . The refrigerator of  claim 8 , wherein the machine room has an opened surface toward a side surface of the case, and the machine room cover covers the opened surface. 
     
     
         11 . The refrigerator of  claim 10 , wherein the communication duct is formed on a rear surface of the case so as to be adjacent to the opened surface of the machine room. 
     
     
         12 . The refrigerator of  claim 9 , wherein each of the second vents is formed to have a size increased toward a side surface of the condenser case, from a connection passage of the condenser case communicated with the guide duct. 
     
     
         13 . The refrigerator of  claim 1 , wherein the condenser is implemented as refrigerant pipes for passing a refrigerant are curved a plurality of times on the same plane. 
     
     
         14 . The refrigerator of  claim 6 , wherein the communication portion is provided so as to have a decreased sectional area in a flow direction of air by the blowing fan. 
     
     
         15 . The refrigerator of  claim 4 , wherein the blowing fan is implemented as a cross flow fan. 
     
     
         16 . The refrigerator of  claim 5 , wherein the blowing fan is implemented as a cross flow fan. 
     
     
         17 . The refrigerator of  claim 6 , wherein the blowing fan is implemented as a cross flow fan. 
     
     
         18 . The refrigerator of  claim 11 , wherein each of the second vents is formed to have a size increased toward a side surface of the condenser case, from a connection passage of the condenser case communicated with the guide duct.
