The third storage chamber damper 180 may be installed between the common flow path S8 and the first flow path S5 or in the first flow path S5. When the third storage chamber damper 180 is opened, the air in the common flow path S8 may flow through the first flow path S5 to the flow path guide 170 and the multi-duct 150, and the flow guide 170 and the multi-channel The air flowing through the duct 150 may be discharged to the third storage chamber R3 through a plurality of air discharge ports of the multi-duct 150. When the third storage chamber damper 180 is closed, the air in the common flow path S8 does not pass through the first flow path S5 and may flow toward at least one of the second flow path S6 and the third flow path S7. have.

The fourth storage chamber damper 190 may be installed between the common flow path S8 and the second flow path S6 or in the second flow path S6. When the second storage chamber damper 190 is opened, the air in the common flow path S8 may pass through the second flow path S6, and through the second flow path S6, the air in the discharge guide duct 18 shown in FIG. It may flow, and may be discharged to the fourth storage chamber R4 through the cold air discharge passage P′ of the second barrier B2. When the fourth storage chamber damper 190 is closed, the air in the common flow path S8 does not pass through the second flow path S6 and may flow toward at least one of the first flow path S5 and the third flow path S7. have.

The defrost damper 200 may be installed between the common flow path S8 and the third flow path S7 or in the third flow path S7. When the defrost damper 200 is opened, the air in the common flow path S8 may be guided to the rear of the shroud 160 through the third flow path S7, and then may flow toward the evaporator 17. When the defrost heater 31 is installed between the outlet of the third flow path S7 and the evaporator 17 in the flow direction of air, the air flows to the defrost heater 31 after passing through the third flow path S7. It can be heated by the defrost heater 31, and then flows to the evaporator 17 to defrost the evaporator 17 in a convection manner. When the defrost heater 31 is installed in the third flow path S7, the air is heated by the defrost heater 31 while passing through the third flow path S3, and after passing through the third flow path S7, the evaporator ( It is possible to flow to 17) to defrost the evaporator 17 in a convection manner. When the defrost damper 200 is closed, the air in the common flow path S8 may not pass through the third flow path S7 and may flow toward at least one of the first flow path S5 and the second flow path S6.

In the kimchi refrigerator, when the third storage compartment is cooled, the defrost heater 31 is turned off, the fan 29 is driven, the third storage compartment damper 180 is open, and the fourth storage compartment damper 190 and the defrost damper 200 ) May be closed. When the fan 29 is driven, 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. It may flow through the common flow path S8. The air in the common flow path S8 cannot flow to the second flow path S6 and the third flow path S7 because both the fourth storage compartment damper 190 and the defrost damper 200 are closed, and the fourth storage compartment damper 190 ) And the defrost damper 200 may flow into the first flow path S5. The air flowing through the first flow path S5 may pass between the flow path guide 170 and the multi-duct 150 and then be discharged to a plurality of air outlets of the multi-duct 150. Air discharged through the plurality of air outlets of the multi-duct 150 may cool the third storage chamber R3 and then pass through the lower portion of the fan assembly 27 to flow to the evaporator 17.

In the kimchi refrigerator, when the fourth storage compartment is cooled, the defrost heater 31 is turned off, the fan 29 is driven, the fourth storage compartment damper 190 is open, and the third storage compartment damper 180 and the defrost damper 200 ) May be closed. When the fan 29 is driven, air may be cooled by a refrigerant passing through the evaporator 17 and may flow into the air suction hole 162 of the shroud 160. The air cooled by the evaporator 17 may pass through the air suction hole 162 of the shroud 160 and flow into the common flow path S8. The air in the common flow path S8 cannot flow to the first flow path S5 and the third flow path S7 because both the third storage chamber damper 180 and the defrost damper 200 are closed, and the first storage chamber damper 180 ) And the defrost damper 200 may flow into the second flow path S6. After passing through the duct part 168, the air flowing through the second flow path S6 may flow to the discharge guide duct 18 shown in FIG. 2, and the cold air discharge flow path P1 of the second barrier B2 It may be discharged to the fourth storage chamber R4 through. The air discharged to the fourth storage chamber R4 may cool the fourth storage chamber R4, and then may flow to the rear of the shroud 160 and flow to the evaporator 17.

In the kimchi refrigerator, when the evaporator 17 is defrosted, the defrost heater 31 is on, the fan 29 is driven, the defrost damper 200 is open, the third storage chamber damper 180 and the fourth storage chamber damper (190) may be closed. When the fan 29 is driven, air may pass through the air suction hole 162 of the shroud 160 and flow into the common flow path S8. The air in the common passage (S8) cannot flow to the first passage (S5) and the second passage (S6) because both the third storage chamber damper 180 and the fourth storage chamber damper 190 are closed, and the third storage chamber damper It is blocked by 180 and the fourth storage chamber damper 190 and may flow into the third flow path S7. The air flowing through the third flow path S7 may be heated by the defrost heater 31 and then flow to the evaporator 17, and may defrost the evaporator 17 while passing through the evaporator 17.
