ABSTRACT:
An ice making has an ice making mold with a plurality of ice making cells opened at the bottom, a water tank, water spray nozzles adapted for spraying the water contained in the water tank towards the ice making cells, an ice bin adapted for storage of ice cubes formed in and harvested from the ice making cells, and an inclined plate having water spray openings and recovery openings and mounted between the ice making mold and the water spray nozzles. The ice making cells are each attached to a serpentine evaporator tube, which is cooled by a refrigeration system and also heated by way of electrical pulse energy. The electrical pulse heating of the ice making cells allows ice to be quickly and efficiently harvested from the cells.
