 The Kimchi refrigerator is operated in the third storage chamber cooling operation when the defrost heater 31 is off and the fan 29 is driven and the third storage damper 180 is open and the fourth storage damper 190 and defrost damper 200 ) May be closed. When the fan 29 is driven, the air can be cooled by the refrigerant passing through the evaporator 17, and the air cooled by the evaporator 17 passes through the air suction hole 162 of the shroud 160 And flow to the common flow path S8. The air in the common flow path S8 can not flow into the second flow path S6 and the third flow path S7 because the fourth storeroom damper 190 and the defrost damper 200 are both closed and the fourth storeroom damper 190 ) And the defrost damper (200) to flow into the first flow path (S5). The air that has flowed to the first flow path S5 may pass between the flow guide 170 and the multi-duct 150, and may be discharged to a plurality of air outlets of the multi-duct 150. Air discharged to the plurality of air discharge openings of the multi-duct 150 can cool the third storage room R3 and then flow to the evaporator 17 through the lower portion of the fan assembly 27. [

 In the Kimchi refrigerator, when the fourth storage chamber is cooled, the defrost heater 31 is turned off, the fan 29 is driven, the fourth storage damper 190 is open, the third storage damper 180 and the defrost damper 200 ) May be closed. When the fan 29 is driven, the air can be cooled by the refrigerant passing through the evaporator 17 and can flow into the air suction hole 162 of the shroud 160. The air cooled by the evaporator 17 can flow through the air intake hole 162 of the shroud 160 and into the common flow path S8. The air in the common flow path S8 can not flow into the first flow path S5 and the third flow path S7 because the third storage chamber damper 180 and the defrost damper 200 are both closed, ) And the defrost damper (200) to flow into the second flow path (S6). The air that has flowed into the second flow path S6 can flow into the discharge guide duct 18 shown in FIG. 2 after passing through the duct portion 168, and can flow through the cold air discharge path P1 of the second barrier B2, To the fourth storage chamber R4. The air discharged to the fourth storage chamber R4 can cool the fourth storage chamber R4 and then flow to the rear of the shroud 160 and flow to the evaporator 17. [

In the Kimchi refrigerator, when the evaporator 17 is defrosting, the defrost heater 31 is on, the fan 29 is driven, the defrost damper 200 is open, and the third storage damper 180 and the fourth storage damper (190) may be closed. At the time of driving the fan 29, air can flow through the air suction hole 162 of the shroud 160 and into the common flow path S8. The air in the common flow path S8 can not flow into the first flow path S5 and the second flow path S6 because the third storage damper 180 and the fourth storage damper 190 are both closed, (180) and the fourth storage chamber damper (190) to flow into the third flow path (S7). The air that has flowed to the third flow path S7 can be heated by the defrost heater 31 and flow to the evaporator 17 and can defrost the evaporator 17 while passing through the evaporator 17. [
