When it becomes the state, it is judged that the ice making container 1 is horizontal and
Proceed to step 1 and set to OFF so as to stop the motor 6. . In step 12, the water supply pump motor 4 is set to ON to supply water to the empty ice making container 1, the water supply timer 17 is started in step 13, and the water supply pump 17 is started in step 14 until the water supply timer 17 times out. The motor 4 is operated. When the water supply time 17 is up in step 14, the water supply pump motor 4 is set to OFF so as to be stopped in step 15.

Go to 6. In step 16, the motor 6 is set to OFF so as to be stopped, and in step 17, the first timer 18 is started. In step 18, the first timer 18 waits until a predetermined time is reached, and when the predetermined time is reached, the process returns to step 5 to perform the ice detecting operation again.
