ABSTRACT:
Dislosed is an automatic ice making machine having a constitution in which a water to be frozen stored within a water tank is fed under pressure to a distributor pipe via a pump and injected through injection holes formed along said distributor pipe into a freezing chamber cooled by an evaporator connected to a freezing system, to form ice cakes within said freezing chamber, while part of the freezing water which is not frozen within said freezing chamber is fed back to said water tank for recirculation, characterized in that said ice making chamber consists of a first freezing chamber having formed thereon a multiplicity of downwardly opening first freezing cells of a predetermined recessed shape, with said evaporator disposed on its rear surface; and a second freezing chamber having formed thereon a multiplicity of second freezing cells of a predetermined recessed shape, which is disposed relative to said first freezing chamber such that the former may be moved closer to or spaced from the latter, wherein said second freezing cells close the corresponding first freezing cells from downside, respectively, to define ice forming spaces of a spherical or polyhedral shape therebetween during the freezing operation.
