A major appliance, or domestic appliance, is a large machine used for routine housekeeping tasks such as cooking, washing laundry, or food preservation. An appliance is different from a plumbing fixture because it uses electricity or fuel. Major appliances differ from small appliances because they are bigger and not portable. They are often considered fixtures and part of real estate and as such they are often supplied to tenants as part of otherwise unfurnished rental properties. Major appliances may have special electrical connections, connections to gas supplies, or special plumbing and ventilation arrangements that may be permanently connected to the appliance. This limits where they can be placed in a home. Many major appliances are made of enamel-coated sheet steel which, in the middle 20th century, was usually white. The term white goods or whiteware,〔("Energy Star Products" ) ''Energy Star.govt.nz''〕 in contrast to brown goods, is also used, primarily where British English is spoken, although definitions for the term "white goods" can differ. In the United States, the term ''white goods'' more commonly refers to linens rather than appliances.〔(" 'white goods' - Definition - Merriam-Webster" ) ''Merriam-Webster Online Dictionary''〕 Since major appliances in a home consume a significant amount of energy, they have become the objectives of programs to improve their energy efficiency in many countries. Energy efficiency improvements may require changes in construction of the appliances, or improved control systems. ==Brands== (詳細はelectrification, many major consumer appliances were made by the same companies that made the generation and distribution equipment. While some of these brand names persist to the present day, even if only as licensed use of old popular brand names, today many major appliances are manufactured by companies or divisions of companies that specialize particular appliances. 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「major appliance」の詳細全文を読む スポンサード リンク
