An icemaker, ice generator, or ice machine may refer to either a consumer device for making ice, found inside a home freezer; a stand-alone appliance for making ice, or an industrial machine for making ice on a large scale. The term "ice machine" usually refers to the stand-alone appliance. The ''ice generator'' is the part of the ice machine that actually produces the ice. This would include the evaporator and any associated drives/controls/subframe that are directly involved with making and ejecting the ice into storage. When most people refer to an ice generator, they mean this ice-making subsystem alone, minus refrigeration. An ''ice machine'', however, particularly if described as 'packaged', would typically be a complete machine including refrigeration and controls, requiring only connection to utilities. The term ''icemaker'' is more ambiguous, with some manufacturers describing their packaged ice machine as an icemaker, while others describe their generators in this way. ==History== In 1748, the first known artificial refrigeration was demonstrated by William Cullen at the University of Glasgow.〔http://inventors.about.com/library/inventors/blrefrigerator.htm The first artificial refrigeration demonstration〕 In 1844, an American physician, John Gorrie, built a refrigerator based on Oliver Evans' design to make ice to cool the air for his yellow fever patients. In 1851, John Gorrie was awarded US Patent 8080 for an ice machine. In 1853, Alexander Twining was awarded US Patent 10221 for an icemaker. In 1855, James Harrison received a similar patent for an icemaker in Australia. In 1867, Andrew Muhl built an ice-making machine in San Antonio, Texas, to help service the expanding beef industry before moving it to Waco in 1871.〔(【引用サイトリンク】title=Refrigeration )〕 In 1873, the patent for this machine was contracted by the Columbus Iron Works, which produced the world's first commercial icemakers. William Riley Brown served as its president and George Jasper Golden served as its superintendent. In 1902, the Teague family of Montgomery purchased control of the firm. Their last advertisement in ''Ice and Refrigeration'' appeared in March 1904.〔Columbus Iron Works, 1853, Historic American Engineering Record, Heritage Conservation and Recreation Service, Department of the Interior〕 In 1925, controlling interest in the Columbus Iron Works passed from the Teague family to W.C. Bradely of W.C. Bradley, Co.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「icemaker」の詳細全文を読む スポンサード リンク
