Claims

[Claims for Utility Model Registration] 1. An ice-making compartment provided in a freezer compartment, comprising: a damper for controlling the amount of cold air supplied to the ice-making compartment; and a shape-memory member located near an ice-making tray in the ice-making compartment. and increasing the amount of cold air supplied to the ice making compartment during ice making and decreasing the amount of cold air supplied to the ice making compartment at the end of ice making by displacing the shape memory member according to the temperature of the ice making tray. A refrigerator characterized in that the damper is configured to open and close. 2. The refrigerator according to claim 1, wherein the shape memory member is covered with a heat conductive cover that is in heat conductive contact with the ice tray. 3. The shape memory member is provided with a heat insulating member for blocking cold air in the freezer compartment on a surface other than the surface on the ice tray side, as described in claim 1 or 2 of the utility model registration claim. refrigerator.
