Referring to these drawings, the refrigerator 1 may supply cool air to the inside of the ice making chamber 100 in a state where the refrigerating chamber door 22 in which the ice making chamber 100 is formed is closed.

That is, in the state in which the refrigerating compartment door 22 is closed, the gasket 200 comes into contact with the inner case 400 of the main body 10. Accordingly, the ice making chamber 100 and the cold air duct 300 communicate with each other, so that the cold air generated at the evaporator 14 side passes through the supply duct 310 and the cold air inlet 140 in order. The air supplied to the ice chamber 100 and heat-exchanged in the ice making chamber 100 is guided to the evaporator 14 through the cold air discharge port 150 and the return duct 320 in turn so that the entire cold air is circulated. do.

In this case, the gasket 200 is in close contact with the inner case 400, and the duct deco 500 is located inside the cold passage of the gasket 200. Therefore, all the cold air entering and exiting through the duct deco 500 passes through the gasket 200, and there is no cold air leaking out of the gasket 200.

In addition, since the duct deco 500 is completely located inside the gasket 200, even some of the cold air leaked through the gap of the mounting part 440 on which the duct deco 500 is mounted is provided in the gasket 200. ) Will not leak outside.

In addition, the heater 410 is operated by a predetermined program or continuously maintained. The heat generated by the driving of the heater 410 heats one side of the inner case 400 along the heat transfer member 420, and in particular, heats a portion where the gasket 200 is in contact with the gasket 200. This will prevent sexual intercourse or freezing.

Therefore, the cold air guided to the ice making chamber 100 or the evaporator 14 through the cold air duct 300 can be smoothly flowed without leaking to the outside.
