ABSTRACT:
A plurality of freezing cells opening downwardly are defined like a grid in a freezing chamber of an injection type ice making machine. The freezing chamber, which is made of a metal having good thermal conductivity, is coated on the surface with a material containing a substance having an antibacterial substance. Contaminant-free ice cubes are adapted to be formed by the thus formed coating layer. As a material of this coating layer, a melt of tin (96.5%) and silver (3.5%) can be suitably used.
