  • Patent number: 10180275
    Abstract: An ice making duct for a refrigerator unit includes a cooling duct configured to allow cooling air to be movable in a longitudinal direction therein. Both ends of the cooling duct are connected to an ice making chamber such that the cooling air circulates through the ice making chamber. The ice making duct includes an evaporation coil configured to be wound around the cooling duct. The evaporation coil cools air in the cooling duct to generate cooling air through a process of heat exchange with a refrigerant. The ice making duct includes a heater configured to heat frost generated in the cooling duct forming defrosted water.
