  • the pressure of the ice making water is high for being close to the circulation pump P.
  • the dimension of the inner diameter is smaller by providing the depression 40 on the ice making water supply tube 12 , a turbulent flow is generated when the ice making water passes through the depression 40 as illustrated in FIG. 3 . Because of this, the water spray hole 38 near the depression 40 does not become at a negative pressure, making it possible to supply the ice making water smoothly through the water spray hole 38 .

That is, the ice making water does not scatter to other than the ice making water tank 66 by way of the oblique sides 68 .
  • the vertical dimension can be approximately half compared to that of a guide piece having a slope inclined only in one direction. Accordingly, the ice guiding member 60 can be made vertically smaller and thus the flow-down type ice making machine 30 can be downsized. Moreover, as long as the guide pieces 62 are in an angle shape, the center can be disposed extremely close to the lower ends of the ice making plates 22 and thus the distance of the oblique sides 68 , 68 apart from the ice making plates 22 , 22 does not become enlarged. Therefore, the spatter of the ice making water dropping down on the oblique sides 68 , 68 is small, enabling to prevent it from being splashed to other than the ice making water tank 66 .

  • the overflow member 80 since the overflow member 80 according to this embodiment has the main body 82 and the partition wall 84 formed integrally with the ice making water tank 66 , it can prevent generation of malfunctions due to defects in mounting and the like, enabling the assembly costs to be inexpensive compared to the case of a separate configuration.
  • the ice making water does not vigorously escape from the water spray guides 46 as it does conventionally. Accordingly, it is possible to prevent the ice making water from being supplied intensively to the ice making surfaces 20 partially to form deformed ice. In addition, it is possible to prevent the ice making water from scattering to other than the ice making unit 16 from the water spray guides 46 to generate unexpected troubles.
