- the side duct may include a straight part extending parallel to the side of the case of the ice maker, and an inclined part extending in a direction approaching the side of the case from the front end of the straight part.
- the cold air discharged from the side duct may be concentratedly supplied to the space in front of the ice maker by the structure of the end of the inclined portion where the outlet is formed, thus ensuring the cooling performance of the space in front of the ice maker.
- a plurality of grills are provided at the outlet of the side duct to uniformly supply cold air, and in particular, the grill is formed to have directionality, and cold air discharged from the outlet of the side duct is provided in the space in front of the ice maker and There is an advantage in that it can be more effectively supplied to the freezer door basket.
- a side opposite to the position where the side duct is disposed among the left and right side surfaces of the ice maker may be spaced apart from the side wall surface of the storage space by a set interval.
- the guide duct is branched into an ice maker supply unit and a side supply unit, and some of the cold air discharged from the outlet and flowing into the guide duct is supplied to the ice maker, and the remaining part is supplied along the space between the ice maker and the side wall surface. It can flow and be supplied to the front of the ice maker.
- cold air may be supplied along both sides of the ice maker by the guide duct and the side duct, and the space in front of the ice maker may be more effectively cooled.
