Automatic ice making machine

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 a part of the freezing water which is not frozen within said freezing chamber is fed back to said water tank for recirculation, comprising:

• 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;
• a second freezing chamber having formed thereon a multiplicity of upwardly opening second freezing cells of said predetermined recessed shape, said second freezing chamber being disposed subjacent to and movable relative to said first freezing chamber between said first and second freezing cells during the freezing operation;
• and
• an ice guide means which is pivotally supported at a portion below said second freezing chamber to block usually the locus along which the ice cakes drop, and, when said second freezing chamber is tilted off from said first freezing chamber during the ice removing operation, urged to fall over the upper surface of said second freezing chamber to guide the ice cakes dropping said first freezing chamber into an ice reservoir.

• 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;
• 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 for 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;
• and
• an ice guide means which is pivotally supported at a portion below said second freezing chamber to block usually the locus along which the ice cakes drop, and, when said second freezing chamber is tilted off from said first freezing chamber during the ice removing operation, urged to fall over the upper surface of said second freezing chamber to guide the ice cakes dropping said first freezing chamber into an ice reservoir, said ice guide means being provided on a shaft which is pivotally supported obliquely below said second freezing chamber and above the ice reservoir such that said means may be urged by a member which can be titled integrally with said second freezing chamber, to fall over the upper surface of said second freezing chamber when said second freezing chamber is tiltingly spaced apart from said first freezing chamber during the ice removing operation, while said means may be spaced apart from the upper surface of said second freezing chamber interlocking with the action of said second freezing chamber to approach said first freezing chamber to resume its initial posture.
