PROBLEM TO BE SOLVED: To provide a new mechanism for producing transparent ice in an ice-making device for a refrigerator-freezer. SOLUTION: The ice-making device 10 is installed in an ice-making chamber 4 of the refrigerator-freezer 1. The ice-making device 10 includes: a chill tray 20 for making ice by cold air blown into the ice-making chamber 4; a thermistor 25 for measuring a temperature in the chill tray 20; a heater 31 for heating the chill tray 20 from the lower side; and a control part 50 for performing the operation control of a refrigerating cycle and the current-carrying control of the heater 31 by using the measured temperature by the thermistor 25 as a criterion. A cold air discharge port 13 of the ice-making chamber 4 includes: a remote discharge port 13a oriented to a remote portion viewed from the cold air discharge port 13 of the chill tray 20; and a near discharge port 13b oriented to a near portion viewed from the cold air discharge port 13 of the chill tray 20. A discharge air quantity from the remote discharge port 13a is set smaller than that from the near discharge port 13b. COPYRIGHT: (C)2011,JPO&INPIT
