圧縮機が運転を再開して初めて製氷完了となる。In the conventional refrigerator-freezer with an automatic ice maker, the operation of the compressor is stopped by the operation of the compressor.
By comparing the stop temperature and the freezing room temperature detected by the freezing room temperature sensor, the freezing room temperature detected by the freezing room temperature sensor is stopped because the operation is performed independently of the operation of the automatic ice making machine. When the temperature becomes lower than the temperature, the operation of the compressor is stopped regardless of the temperature just before the ice tray temperature detected by the ice tray temperature sensor reaches the ice making completion temperature or lower. If the operation of the compressor is stopped just before the completion of ice making, the ice making is not completed immediately, but the ice making is completed only after the compressor is restarted.

If the freezing room temperature detected by the freezing room temperature sensor again becomes equal to or higher than the compressor operating temperature and the time until the freezing room temperature becomes equal to or higher than the compressor operating temperature is long, one ice-making operation is performed accordingly. It will take a long time.

Since the start / stop temperature decreases and the operating rate of the compressor increases, the temperature inside the freezer compartment is maintained at a lower temperature during ice making than during non-ice making, and as a result, the ice making time in summer when the outside air temperature is high is shortened. The daily amount of ice making also increases.
