ABSTRACT:
An automatic ice maker includes an ice tray supplied with water, which water is made into ice. After the water in the ice tray is made into ice, the ice tray is inverted so that ice cubes are removed from the ice tray. During the ice making stage, a vibrator vibrates the ice tray so that the ice making at the water surface side in the ice tray is retarded, which causes air bubbles contained in the water in the ice tray to escape therefrom, thereby providing transparent ice cubes.
