The development history of electric heaters
2022-08-23
The development of electric heaters, like other industries, follows these rules:
1. Gradually spread from advanced countries to all countries in the world.
2. Gradually develop from cities to rural areas.
3. From the collective use to the family, and then to the individual.
4. Products are developed from low-grade to high-grade.
Most of the electric heaters produced in the 19th century were clumsy. They appeared as electric heaters for life. In 1893, the prototype of the electric comfort bucket first appeared and used in the United States, and then the use of electric stoves appeared in 1909. Placing an electric heater in the stove means that the heat is transferred from the firewood to the electricity, that is, from electrical energy to thermal energy. However, the rapid development of the electric heater industry followed the invention of nickel-chromium alloys used as electric heating elements. In 1910, the United States first successfully developed an electric heater made of nickel-chromium alloy heating wire, which fundamentally improved the structure of the electric heater, and the use of heaters was rapidly popularized. By 1925, the product that installed electric heating elements in the pot appeared in Japan, which became the prototype of modern electric heaters. At this stage, electric heating products such as laboratory electric furnaces, glue melting furnaces, and heaters also appeared in the industry. From 1910 to 1925, it was a major development stage in the history of electric heaters. In the domestic and industrial aspects, the emergence and popularization of various varieties have achieved rapid development, especially in the family. Therefore, the invention of nickel-chromium alloy laid the foundation for the development of electric heater industry.
After the 1920s, there were not as many new applications and development as the previous period, but during this period, all kinds of electric heaters were redesigned and continuously improved, becoming an improved stage in the history of electric heaters. In terms of household electric heaters, all kinds of appliances are designed to be more beautiful, durable and sturdy, and most of them have automatic temperature and time control, so they cannot be used illegally, durable and sturdy, and most of them have automatic temperature and time control. Time control, so the possibility of improper use, temperature difference and disaster can be avoided. Like electric stoves, toasters, pancakes, etc. have automatic control. At the same time, the manufacturing materials have also been improved, such as the use of A-grade nickel-chromium wire with good quality, and magnesium oxide or zirconia as insulators. In terms of industry, like household heating appliances, the use of automatic control devices and the use of good materials, such as wax melting pots, lead melting furnaces, various large ovens, heat treatment furnaces, etc., have been widely improved and applied. After the 1940s, due to the advancement of science and technology in the United States, low electricity costs, war money, and relatively high income, electric heaters have entered the stage of popularization. In 1940, the penetration rate of teleconsolation in American households reached the awareness of the situation. Before the liberation of our country due to imperialist aggression and the rule of the reactionaries, the heater industry has been in a very backward state. Only after the liberation has been continuously developed, especially in recent years, more types of electric heaters such as heat transfer oil heaters and heaters have been invented and produced, and the heater market can develop by leaps and bounds.
