Abstract: An auger-type ice maker comprises partitions 16 projectingly provided on the outer periphery of a pressing head 9 which has been inserted and fixed to the upper portion of an ice-making cylinder 1, wherein fixed blades 25 are formed at the lower portion of the partitions 16 so as to be offset in the radial direction, and wherein the tip of the inner circumference side portion 20a thereof is situated above the greater diameter portion of the auger 6 provided with a spiral blade 5. In the above construction, the offset corner portion 20c is provided with a curvature. Accordingly, ice can be prevented from being compressed to and adhering to the corner portion 20c. Thus, the transporting resistance of ice at the lower portion of the partitions projectingly provided to the outer periphery of the pressing head can be reduced, thereby preventing decreasing in ice-making capabilities and abnormal sounds or vibrations being emitted owing to ice jamming occurring.

Abstract: An auger is accommodated in a vertically disposed cylindrical refrigerated casing for scratching an ice layer made around the inner periphery of the refrigerated casing and feeding the scratched ice upward. The auger includes a columnar main body and a spiral blade disposed around the outer periphery of the main body. The cross section of the spiral blade in the axial direction of the main body is formed of an upper end surface extending outward in a radial direction from the main body, a lower end surface spaced axially from the upper end surface and extending outward in the radial direction from the main body, and a tapered surface linearly connecting both the extreme ends of the upper end surface and the lower end surface. The tapered surface extends upwardly and radially inwardly from a radially outermost portion of the extreme end of the lower end surface.

Abstract: A bearing structure for an auger-type ice making machine 10 includes an auger 17 having a helical blade 17a which rotates within a cylindrical refrigeration casing 11 so as to scrape off ice generated on the inner surface of the refrigeration casing 11 and push it up and out of the casing. A slide bearing 27 for supports an upper shaft section 17b of the auger 17 and a press head 25 is provided inside the upper end portion of the refrigeration casing 11 and which supports the slide bearing 27. Even if the upper shaft section 17b of the auger 17 and the press head 25 axially relatively move as a result of the scraping oil and feeding-out of the ice, substantially closed first and second foreign matter trapp spaces A and B are formed in close proximity to the lower and upper ends of the slide bearing. Further, a high-hardness metal layer 17f having a thickness, for example, of approximately 0.5 mm is formed on the surface of the upper shaft section 17b of the auger 17.
