A brief introduction to electric heaters

Electric heating is the process of converting electric energy into heat energy. Since the discovery that power supply can generate heat effect through wires, many inventors in the world are engaged in the research and manufacture of various electric heating appliances. The development and popularization of electric heating follow the same rule as other industries: gradually spread from advanced countries to all countries in the world; From cities to rural areas; From collective use to family, and then to individual; The product develops from low grade to high grade. Burgeoning electric appliances in the 19th century were mostly poor, the first is used in electric appliances, 1893 DianWei bucket type of cheeper first appeared in the United States and use, and then to the use of electric cooker appeared in 1909, it's electric heater is placed in the oven, that is heated from firewood to electric, that is, from electrical energy into heat energy. But the real boom in the heating industry came with the invention of nickel-chromium, which is used as a heating element. In 1910, the United States first developed the comfort bucket made of nickel-chromium alloy heating wire, which fundamentally improved the structure of the comfort bucket and quickly popularized its use. By 1925 in Japan appeared in the pot installed heating element products, become the prototype of the modern rice cooker. In this stage industry also appeared in the laboratory electric furnace, melting glue furnace, heater and other electric products. The period from 1910 to 1925 was a great stage of development in the history of electric heating appliances. Therefore, the invention of nickel-chromium alloy laid the foundation for the development of electric heating industry.
