Electric heating is a process of converts electrical energy into heat energy. Since found that the power supply through a wire can occur after heating, is many inventors in the world is engaged in research and manufacture of various kinds of electric appliances. The development and popularization of electric applications like other industries, also follows such a pattern: from advanced countries gradually spread to the world of electric heater; Gradually developed from the city to the countryside; By the collective use development to family, and personal; Products 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 electric appliances industry, with the rapid development of electric heating component is used after the invention of nickel-chromium alloy. In 1910 the United States first developed with nickel chromium alloy heating wire made of iron, it is fundamentally improved iron structure, using the iron quickly gained popularity. In 1925 in Japan in the pot to install electric heating element products, become the prototype of the modern electric rice cooker. Use the electric stove in also appears on the stage of industrial laboratory, melt furnace, heating device and other electric products. From 1910 to 1925, is a big stage of development in the history of the electric appliances, in domestic and industrial electric appliances appear a variety of application got rapid development and popularization, and especially in the family. So the invention of the nickel chromium alloy is to lay the foundation for the development of the electric appliances industry.

After 20 s in new application development on no more than a period, but at this stage all have various electric appliances are set in order and continuous improvement, become raise stage in the history of the electric appliances. In terms of household electric appliances, all kinds of instruments are designed to be more beautiful, durable and strong, and most have automatic temperature and control.
