When external power is applied to the refrigerator main body 100, the electric devices and components inside the main body 100 operate. The refrigerant flowing in the evaporator inside the main body 100 by the operation of the electric device and components exchanges heat with the air in the refrigerating chamber 200 and the freezing chamber 300 to heat the temperature of the refrigerating chamber 200 and the freezing chamber 300. Will be lowered to a temperature suitable for food storage.

In addition, some of the cold air generated by the freezer compartment evaporator 360 cooling the freezer compartment 300 moves to the ice making chamber 400 through the suction port along the cold air duct 380. The cold air introduced into the inside of the) is supplied to the ice maker 520.

The cold air supplied to the ice maker 520 exchanges heat with the water stored in the ice maker 520, and thus ice is made in the ice maker 500 inside the ice maker 400. At this time, the speed and the amount of ice is determined according to the amount of cold air supplied from the freezer compartment evaporator (360).

Meanwhile, the cold air that has been heat-exchanged in the ice making chamber 400 is discharged back to the freezing chamber 300 along the cold air duct 380 through the discharge port, and the cold air generated in the freezing chamber evaporator 360 performs this process. Will repeat.

In addition, the ice that has completed the ice making operation by exchanging heat with cold supplied from the freezing chamber evaporator 360 in the ice making chamber 400 is stored in the storage case 542 of the ice bank 540, and the storage case 542. Ice is stored in the) is delivered to the ice maker (移 氷 幾, 640).

Therefore, when a user operates the dispenser 240 as necessary, the ice maker 544 operates to guide some of the ice stored in the ice making chamber 400 to the discharge port 480 so that the dispenser 240 ), And the user can take out ice from the outside through the dispenser 240.

On the other hand, looking at the assembly process of the ice making room 400, the ice maker 520 and the ice bank 540 made of each component is mounted at the designated position of the support plate 600 and the ice maker 520 and the The ice bank 540 is mounted to seat the support plate 600 integrally formed inside the ice making chamber 400.
