A capacity of the retention tank section 60 is set to have a capacity greater than that of the circulating tank section 58. Above the retention tank section 60 is covered with a guide 52c of a mechanical base 52, and the un-iced water cooled during ice-making operation is collected only into the circulating tank section 58 via an opening 52d opening downward above the circulating tank section 58.

Abstract: An automatic ice making machine stably injects water to be frozen to freezing cells to produce high-quality ice pieces which are uniform in shape and size, and has a freezing section defining a plurality of freezing cells opening downward and arranged horizontally, and a water tank located under the freezing section. A water spraying member tilted at a predetermined angle in the flow direction is disposed on the water tank, and a plurality of nozzles protrude from the upper surface of a distributor pipe constituting the member. The water to be frozen supplied to the water spraying member by a water circulation pump is adapted to be injected into each freezing cell through a water injection hole of each nozzle under the same pressure. Further, the water to be frozen injected from each water injection hole diagonally forward is designed to be supplied to an opposed freezing cell.
