Electric heating is the process of converting electrical energy into thermal energy. Since the discovery that power sources can undergo thermal effects through wires, many inventors around the world have been engaged in the research and manufacturing of various electric heating appliances. The development and widespread application of electric heating, like other industries, follow this pattern: gradually promoting from excellent to various countries around the world; Gradually developing from cities to rural areas; From collective use to family and then to individuals; The product has evolved from low-end to high-end. Most of the budding electric heating appliances in the 19th century were poor, and they were originally used for daily life. In 1893, the prototype of the electric console first appeared and was used in the United States, followed by the use of electric stoves in 1909. That is to say, an electric heater was placed in the stove, which means that heating is transferred from firewood to electricity, that is, from electrical energy to thermal energy. But the rapid development of the real electric heating industry came after the invention of nickel chromium alloy, which was used as an electric heating element. In 1910, the United States was the first to successfully develop an electric iron made of nickel chromium alloy heating wire, which fundamentally improved the structure of electric irons and quickly popularized the use of irons. By 1925, products with electric heating elements installed in Japanese pots became the prototype of modern rice cookers. In this stage of industry, laboratory electric furnaces, glue melting furnaces, heaters and other electric heating products also appeared. The period from 1910 to 1925 was a period of great development in the history of electric heating appliances. In both the household and industrial sectors, the emergence and widespread application of various types of electric heating appliances saw rapid development, especially in the household sector. So the invention of nickel chromium alloy laid the foundation for the development of the electric heating appliance industry.

After the 1920s, there were not as many new applications and developments as in the previous period, but during this period, all kinds of electric heating appliances were redesigned and continuously improved, becoming a stage of improvement in the history of electric heating appliances. In terms of household electric heating appliances, various appliances are designed to be more beautiful, durable, and sturdy, and most of them have automatic temperature and time control.
