2. Description of the Related Art Generally, some refrigerators have an ice making machine in an ice making chamber. This ice maker supplies water from a water supply tank located in the refrigeration chamber to an ice tray in the ice making chamber by a water supply pump, blows cold air from a cold air outlet located at the back of the ice making chamber, and cools the cold air. This freezes the water in the ice tray.

As an operation of this ice maker, the ice tray in the ice tray is separated and dropped from the ice tray by reversing and twisting the ice tray after freezing, and is stored in an ice storage box below the ice tray.

FIG. 28 shows, for example, Japanese Patent Laid-Open No. 11-1737.
It is a flow chart of the refrigerator shown in No. 32 publication. In the control of this refrigerator, the power is turned on in step S1. Next, in step S2, it is determined whether the door for the ice making chamber or the door for the freezing chamber is opened, and if opened, the process proceeds to step S3. Also,
If it cannot be opened, it is repeated to determine whether the door has been opened again. In step S3, it is determined whether the opened door is closed. Then, if it is closed, the process proceeds to step S4, and if it is not closed, it is repeatedly determined whether or not the reopened door is closed. In step S4, the second fan is rotated for a predetermined time.

As described above, when the moisture outside the refrigerator flows into the ice making chamber by opening and closing the door of the ice making chamber or the freezing chamber, the moisture may cause the second fan to be frosted.
