Talking about the development of home appliance controller industry

China's home appliance industry has gradually grown into a relatively mature industry since its inception in the 1970s and 1980s, and its R & D and production capacity has basically met people's growing consumer demand. With the rapid and healthy development of China's national economy and the continuous improvement of the living standards of urban and rural residents, people are more and more concerned about their own health and living environment, especially in the field of household appliances, the demand for both household appliances and small and medium-sized household appliances is increasing, and the quality of products is also put forward higher and higher requirements: health, energy conservation and environmental protection

as one of the important components of household electrical appliances, household electrical appliances control in outdoor sports fields such as basketball courts and volleyball courts and cultural welfare facilities. The use of tile plastering devices has also gradually grown with the development of the domestic household electrical appliances industry. Its development process can be simply summarized as the following stages

low output and added value, few varieties

in the late 1980s, R & D technology was mainly mastered by foreign-funded enterprises and a few large state-owned household appliance enterprises. China's household appliance market products were mainly in a period of relatively few types and low technical content. With the passage of time, the domestic household appliance industry continued to develop. By the early 1990s, reform and development were further deepened and national policies were further relaxed. Part of the engineering and technical personnel who have been engaged in the research and development of home appliance controllers in foreign-funded enterprises and large state-owned household appliance enterprises for many years, relying on their own work experience and research and development ability, went out of foreign enterprises and began to establish their own small private home appliance controller manufacturing enterprises, engaged in the controller development and supporting business of home appliance enterprises' products. The products are also some small household appliances, such as bread makers, rice cookers, coffee pots, electric fans, air heaters Controllers such as chicken ovens are mainly facing foreign markets. In the market environment at that time, the supporting R & D ability of the controller of the complete appliance enterprises themselves was weak, so they had to transfer part of the supporting production business of the controller to only a few professional controller manufacturers. This has resulted in a large profit margin for the professional manufacturer of home appliance controllers with monopoly technology in the case of less fierce market competition. Although the output is low and the variety is small, it has taken the first step towards success

here is a specific case: an enterprise was originally a small household appliance manufacturer exporting low-end products such as kettles and hair dryers. At that time, the group leaders wanted to expand some kitchen electrical appliances with complex functions and large profit margins, but suffered from the lack of controller research and development ability, so the project had to be shelved for a long time. Later, the company found a professional controller R & D and production enterprise, which is also just starting, and all industries are waiting to flourish. The two sides hit it off and decided to jointly develop several series of bread machine and coffee pot products. After more than half a year of efforts, the first batch of products began to be produced offline and put into the European market within the year of that year. The annual output value of the enterprise increased from tens of millions to 200million yuan in that year, and soared to 600million yuan in the second year. Now the enterprise has grown into one of the leading enterprises in the field of domestic small household appliances

however, the household electrical appliances produced at this stage are relatively low-end products for foreign countries, both in function and quality. They mainly face low-income consumer groups abroad. A bread machine with intelligent control LCD display can only sell for more than ten dollars, and the added value of the products is not high

"board copying era"

after the initial stage of development, the domestic home appliance industry has rapidly risen, such as Midea, Kelon, Yilong and many other large home appliance enterprises. Only a part of the home appliance controllers they need are developed and produced by themselves, and most of the controllers need other enterprises specializing in the production of controllers to provide supporting products. Therefore, while these home appliance enterprises develop themselves, It has also effectively driven other small and medium-sized enterprises supporting and supplying them, built a basic framework for the development of China's household appliance industry, and began the reserve of industrial talents

due to the rapid development of the household appliance industry and the continuous increase in demand, controller manufacturing enterprises have been launched everywhere; However, R & D technology has not been paid attention to. The home appliance controller market once fell into a situation of similar product functions, which triggered a price war. The market competition changed from weak to relatively fierce. The profit space of each controller manufacturer began to decrease significantly, and the interests of each home appliance manufacturer were also greatly affected

with people's pursuit of a higher level of quality of life, at this time, the low-end domestic household appliances sold on the market can no longer meet people's increasing consumption level and consumption capacity. In this case, the controller manufacturing enterprises have bought foreign advanced household electrical appliances that have just been listed, digested and absorbed them on this basis by imitating the design of foreign circuit boards, and began the localization of household electrical appliances with international standards with their own R & D capabilities. Therefore, domestic high-end household appliances with the same functions as foreign products appeared in the market during this period. However, as it is not a self-developed product, the technology is not comprehensive enough. Although it keeps up with the international trend in terms of shape and performance, there is still a big gap in quality and service life. This period is called the "board copying era" in the industry

After two waves of rapid development of the domestic home appliance industry, by the end of the 1990s and the beginning of the 21st century, China's home appliance controller industry had possessed considerable comprehensive strength, which was mainly reflected in the rapid improvement of the technical level, the great leap in the development of the quality system, the substantial increase in industrial concentration, and the saturation of the home appliance industry. With the improvement of the R & D ability of the home appliance industry and the intensification of market competition, more and more low-end products are replaced by high-end products. Controller enterprises realize that if there is no independent R & D ability, first-class management level and core competitiveness of home appliance products, they will soon be eliminated. Therefore, on the one hand, they improve themselves, learn the advanced management and operation experience of foreign enterprises in the cooperation and competition with multinational enterprises, improve the overall level of their enterprises in the competition, and enhance their competitiveness. On the other hand, it has widely cooperated with universities to absorb the advanced control technology of universities, improve its own research and development level, and understand the development information of global household appliances through various channels. Its products have basically reached the international advanced level. At this time, although the controller enterprises' products can keep up with the development of the same industry in the world, their research ability is basically zero, and the development direction of products still needs to be controlled by the international large household appliance enterprises. At the same time, domestic controller manufacturers have also entered the era of low profits. It is difficult for enterprises to make breakthroughs by operating only one product, because the market capacity of specific products is limited, and they are unable to independently develop products with higher technical content, which greatly reduces the pace of rapid development of controller enterprises. Some of these large enterprises have embarked on the path of diversified development

During this period, science and technology fully showed its advantages as the primary productive force. For example, since the 1990s, environmental friendly combustible gases such as liquefied petroleum gas, natural gas and coal gas have always been the preferred heating energy for kitchens in China. Although induction cooker has struggled in China's home appliance market for more than ten years, its cost has always been higher than that of gas stoves, and most people are not very receptive to its heating method. In 2004, the international oil price continued to rise (more than double that in 2002). Taking advantage of this favorable opportunity, induction cooker products began to occupy China's Kitchenware Market on a large scale, and attracted many consumers by taking advantage of their own advantages

induction cooker controller

induction cooker, as a powerful heating platform, adopts the heating principle of magnetic field induced current (also known as eddy current): the magnetic field is generated by the current passing through the coil. When the magnetic line of force in the magnetic field passes through the bottom of the iron appliance, countless small eddy currents are generated, making the appliance itself heat rapidly, which is used to heat and cook food, so as to achieve the purpose of cooking. Its features are:

☆ microcomputer control, small size, light weight, simple operation and convenient use

☆ adopting the principle of electromagnetic induction heating, it has the characteristics of fast heating speed and high thermal efficiency

☆ the induction cooker has no open fire, smoke-free and exhaust gas, and is safe, clean and hygienic

☆ it can be used flexibly, and the frying, frying and boiling are all done. The power is generally 600w-2000w, and the firepower can be adjusted at will

☆ with automatic detection function, once the food is dry and the pot is overheated, the induction cooker will automatically detect and stop heating, which is safer

reed electronics began to study the induction cooker controller as early as the late 1990s by taking advantage of its own R & D and development advantages. Induction cooker controller is the core component of the internal quality of induction cooker, which mainly uses electromagnetic induction technology. Its key technical requirements are thermal efficiency, component attenuation and peak pre tolerance. In this regard, reed electronics chooses according to the grade standard of handicrafts. Even in Germany, which has the most developed manufacturing industry and the most demanding product requirements, such quality is impeccable. Considering the possible adverse effects of electromagnetic wave and thermal radiation on human body, developers give full play to the frequency conversion and microcomputer technology of electromagnetic products, control the electromagnetic wavelength at low frequency, and limit the thermal diffusion to a very small range, almost completely isolating the threat

by the middle of 2004, induction cooker, as the electrothermal cooker with the highest thermal efficiency in the market, was soon favored by people. Almost their mechanical properties have greatly changed to the point that supply exceeds demand. Due to our leading position in technology in China, the induction cooker controller was quickly welcomed by many well-known domestic manufacturers, successfully signed a long-term supply-demand relationship with many well-known domestic household appliance enterprises, and developed a full range of controller products for high, medium and low-end household appliance products

develop your own technology to improve innovation ability

at present and for a long time to come, with the improvement of enterprise management level, the decline of operating costs, as well as the substantial reduction of tariffs on international procurement of raw materials after China's entry into the WTO, the reduction of circulation costs brought about by the reform of circulation channels, the fierce competition between Chinese and foreign brands and other factors, the price of household appliances has become cheaper. Profits are getting lower and lower. With the formation of the global information network, the speed of technology diffusion is accelerated, resulting in the convergence of products and processes in technology, and the competition among enterprises has become extremely fierce, which makes enterprises have to take the road of independent research. Through extensive production, learning and research cooperation with scientific research institutions and key universities, and with the help of the technological development advantages of scientific research institutions, they can do a good job in the transformation of scientific and technological achievements, Only by constantly introducing new technologies and products can we gain a firm foothold in the market

At the same time, high-tech trade barriers will inevitably be strengthened with the intensification of market competition. In this situation, developing our own technology and improving the innovation ability of our country and our enterprises have become the basic requirements of the current enterprise development. Without knowledge and technological innovation, it is very dangerous for enterprises
