2. Description of the Related Art FIG. 3 shows a configuration of an ice making mechanism of a conventional auger type ice making machine. An auger 6 having a spiral blade 2 is provided inside a freezing casing 1 made of a cylindrical member.
It is rotatably supported by an upper bearing 7 and a lower bearing 8. The auger 6 is connected at its lower end to the geared motor 5 via a speed reducer 9. On the inner wall of the freezing casing 1, an ice making unit 3 for forming ice is formed. At the upper part of the freezing casing 1, a fixed blade main body 11 is fixed to a fixed blade cylinder 12 via a bolt (not shown), and forms a fixed blade 10 together with the fixed blade cylinder 12.

Has three long ribs 14 and three short ribs 15 which are alternately arranged on the outer periphery and extend in the axial direction and have different lengths. The long ribs 14 and the short ribs 15 form the circumferential passage walls 16 and 17 of the ice compression passage 13, respectively. The long ribs 14 and the short ribs 15 are provided with lower end portions 19 and 18 each having a tapered and symmetrical acute triangular prism shape. The fixed blade main body 11 is surrounded by a fixed blade cylinder 12 around the periphery thereof. Between the fixed blade main body 11 and the fixed blade cylinder 12, there are six axially extending sections partitioned by a long rib 14 and a short rib 15. Spaces are formed, and these spaces constitute an ice compression passage 13 for compressing ice.

[0004] In FIG. 3, the ice generated in the ice making unit 3 is pushed upward by the rotation of the auger 6 having the spiral blade 2, and is introduced into the ice compression passage 13 of the fixed blade 10. The ice introduced into the ice compression passage passes through the ice compression passage 13 to form a solidified ice column, and is discharged from the ice compression passage 13 as chip ice.

[0005]

However, in such an auger-type ice making machine, if the quality of the ice making water is poor such as a large amount of impurities in the ice making water or the hardness of the ice making water is high, or if the fixed blade 10 is used. When the amount of ice introduced into the fixed blade 10 is small, there is a problem that ice does not solidify in the fixed blade 10 and chip ice cannot be generated. In such a case, the ice pushed up from the auger 6 to the fixed blade 10 is cylindrical ice adhered to the inner surface of the freezing casing 1 and cannot be compressed by the fixed blade 10 and remains unset. It may pass through the fixed blade 10.

Accordingly, the present invention has been made to solve such a problem, and an auger in which ice is likely to solidify even when the quality of ice making water is poor or the amount of ice introduced into the fixed blade is small. An object of the present invention is to provide a fixed blade of an ice maker.
