Frigidaire is the American consumer and commercial appliances brand subsidiary of European parent company Electrolux. Frigidaire was founded as the Guardian Frigerator Company in Fort Wayne, Indiana, and developed the first self-contained refrigerator (invented by Nathaniel B. Wales and Alfred Mellowes) in 1916. In 1918, William C. Durant, a founder of General Motors, personally invested in the company and in 1919, it adopted the name ''Frigidaire''. The brand was so well known in the refrigeration field in the early-to-mid-1900s that many Americans called any refrigerator (of whatever brand) a ''Frigidaire''. The name Frigidaire or its antecedent Frigerator may be the origin of the widely-used U.S.-slang term ''fridge''.〔(Online Etymology Dictionary )〕〔(Dictionary.com )〕 From 1919 to 1979, the company was owned by General Motors. During that period, it was first a subsidiary of Delco-Light and was later an independent division based in Dayton, Ohio. Frigidaire was sold to the White Sewing Machine Company in 1979, which in 1986 was purchased by Electrolux, its current parent. While the company was owned by General Motors, its logo featured the phrase "Product of General Motors", and later renamed to "Home Environment Division of General Motors". The company claims firsts including: * Electric self-contained refrigerator (September, 1918 in Detroit)〔(Wright State University )〕 * Home food freezer * Room air conditioner * 30" electric range * Coordinated colors for home appliances ==Automatic washers== During the years that Frigidaire was owned by General Motors, it was very competitive in the automatic clothes-washing-machine business. Frigidaire engineer Kenneth Sisson, also credited with the design of the incrementing timer used on clothes washers and dishwashers for years to come, designed the Frigidaire automatic washer with the Unimatic mechanism in the late 1930s. Production of the first Frigidaire automatic clothes washers was halted due to World War II and therefore the machine was not formally introduced until 1947. The washing action of a Frigidaire automatic was unique in that the agitator pulsated up and down, a unique departure from the traditional oscillating type. The Frigidaire washers were commonly named for their mechanisms, which, in true General Motors fashion, underwent frequent changes over the years. The Unimatic was in production the longest, for any single Frigidaire mechanism, from 1947 to 1958. The Pulsamatic mechanism, unique in that it pulsated 630 times per minute, was introduced in 1955 for the lower-end models. This became the foundation for the Multimatic, introduced for the 1959 model year. The Multimatic lasted through 1964, as the Rollermatic was brought out for the 1965 lineup. The Rollermatic was unique in that instead of using an oil-filled gearcase, metal and urethane rollers transferred the power within the mechanism. This underwent a slight revision in 1970 for the new eighteen-pound capacity 1-18, which kept the same basic mechanism but differed in that it was belt-driven off of the motor and added a recirculating pump. Besides the unique action, another notable feature of these older washers was the high final spin speed (nicknamed "Rapidry"), 1140 revolutions per minute in the Unimatic, 850 in the Multimatic, and 1010 in the high-end Rollermatic models. When Frigidaire was acquired by White Consolidated Industries in 1979, it abandoned the General Motors design in favor of the Westinghouse-produced top-loading design, as White-Westinghouse was already among its house brands by this time. 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「Frigidaire」の詳細全文を読む スポンサード リンク
