Abstract: A refrigerator includes: a cabinet defining a storage space, a door that opens and closes the storage space, an evaporator generating cold air to thereby reduce a temperature of the storage space, a blowing fan circulating the cold air in the storage space, a grille panel provided at a rear side of the storage space and including a discharge port discharging the cold air into the storage space, and an ice maker disposed at a front side of the grille pan and including a guide duct guiding a flow of the cold air discharged from the discharge port. The guide duct provides a branched passage to thereby guide (i) a portion of the cold air discharged from the discharge port into the ice maker and (ii) remaining portions of the cold air to bypass the ice maker and into a space defined at a front side of the ice maker.

Abstract: A refrigerator includes a cabinet, a door, an ice maker provided in the cabinet or the door, a water supply flow path configured to connect the ice maker to a water supply source outside the cabinet, a filter connected to the water supply flow path to purify water supplied to the ice maker, at least one valve provided in the water supply flow path, and a controller configured to control operation of the ice maker and the valve. The water supply flow path includes an ice maker pipe connected to the ice maker to supply water for ice making and a drain pipe configured to drain water in the water supply flow path to outside of the cabinet. The controller controls the valve to block water supply to the ice maker and drain water through the drain pipe when a drain signal is input.
