製氷機」として特許出願を行なった。However, since this spherical ice is widely used for eating and drinking, its commercial value will decrease unless it is a clear, transparent block of ice that does not become cloudy due to aeration. In addition, it is necessary to be able to produce large quantities of ice, but no automatic ice-making machine for producing spherical ice has hitherto existed that meets this type of requirement. Therefore, the inventor of the present application engaged in the development of an ice making machine capable of producing a large amount of transparent and clear spherical ice, and having obtained a mechanism that fully satisfies the above requirements, the inventor developed the basic concept in January 1988. On the 29th, he filed a patent application for his invention, an "automatic ice maker."
