- Dec 10, 2018 -

Electrical heating is the process of converting electrical energy into thermal energy. Since the discovery of the thermal effects of power through wires, many inventors in the world have been engaged in the research and manufacture of various electric appliances. The development and popularization of electric heating is also the same as other industries, following the law: from advanced countries to countries around the world; from urban to rural areas; from collective use to households to individuals; products from low-end development To the high class. 

The electric heating appliances in the nascent stage of the 19th century were mostly poor. The earliest appeared electric heating appliances for life. In 1893, the prototype of the electric consolation appeared and used in the United States. Then, in 1909, the use of electric stoves appeared. An electric heater is placed in the stove, that is, the heat is transferred from the firewood to the electrical, that is, from electrical energy to thermal energy. However, the rapid development of the real electric appliance industry is after the invention of the nickel-chromium alloy used as an electric heating element. In 1910, the United States first developed an electric comforter made of nickel-chromium alloy electric heating wire, which fundamentally improved the structure of the electric consolation, and the use of comfort quickly became popular. 

By 1925, in Japan, the product of installing electric heating elements in the pot became the original shape of the modern rice cooker. At this stage, there are also electric heating products such as laboratory electric furnaces, melting furnaces, and heaters. From 1910 to 1925, it was a great development stage in the history of electric heating appliances. In the family and industry, the emergence and popularization of various varieties of electric heating appliances have been rapidly developed, especially in the family. Therefore, the invention of nickel-chromium alloy laid the foundation for the development of the electric heating industry.
