When in 1957 the Germans invented the first electric stove, surely did not think, after 40 years, will form an annual output value of China 3.7 billion (2004), the huge industry.
Compared to urban households now use the most common
Cooker Gas stoves, the cooker has some obvious advantages?? Clean
Security , Convenient, and therefore the industry developed rapidly. According to the National AC electrical goods
Technology Economic Information Center of the survey data, the appliance products in recent years the average growth rate of 60%%, and in 2004 became the appliance market is the "golden years"?? As gas throughout the country, gas prices rise, the appliance industry's first production and sales times breaking 10 million units, up to now, the appliance ownership in the country about 30 million units.
Experts pointed out that from another point of view, the appliance market, the rapid development of electric and gas behind the existence of contention between the two energy sources, if the appliance in the future become
Kitchen Preferred Cooking utensils Not only will people
Life Used to bring great changes, and even affect the country's energy strategy, to break the current electricity and gas relative balance situation.
However, the present, the appliance in order to win from this contest, but also the lack of the necessary conditions, such as the limited life of the appliance itself, the State
Electricity Tense situation, difficult to change people's cooking habits, etc..
Technology difficulties Induction heating is the use of electromagnetic induction heating of the cookware directly. Early induction cooker using MOSFET as power management, because of the shortcomings of the limited pressure, blasting machine so prone to the phenomenon. 20th century 90s, IGBT (power tube) the emergence of the appliance industry to bring the "Gospel", which broke the ceiling of the appliance's power, but also greatly improve the safety factor of the induction cooker work environment.
Another core component of the appliance is
Panel . Panel structure is microcrystalline Glass At present there are three products: a white platter, white plate and black plate. One of the fastest growing black plate.
China induction cooker manufacturer Although 500, but the IGBT and senior panel, or can not produce. IGBT markets are Germany
Siemens , Japan Toshiba And three companies controlled by the United States quickly, the three companies accounted for domestic production of the IGBT 98%% market share. Three companies for their own interests, the technology used varies, leading to the mutual capacitive IGBT poor, but also limits the domestic enterprises in the development of technical progress.
Glass is slightly better condition, there are five domestic production cooker panel?? Dai Hing glass, glass ceramics tycoon, Wenzhou Kanger glass, glass ceramics and Jiangsu, Guangdong Puningkedi a new glass factory in Yixing. However, a major manufacturer of high-level panel and foreign brands, including Germany and Japan Short NEG, NANUMI, MIYAWO is the most important of the four brands. As the white flat-panel market share declining in recent years, prices have been falling, the impact of domestic Glass manufacturers affected by this large living space smaller and smaller.
Since 2003, high-level panel on the international market and two key components appeared IGBT
Home Appliances Industry, a rare phenomenon?? Often out of stock, or even prevent many of the domestic appliance business marketing plan. This shows that our core technology in induction cooker lack of initiative, "Gate of Life" is still controlled in the hands of others. Industry pointed out that if this situation for a long time to exist once the political situation of international economic fluctuations, the appliance industry in China will face a catastrophic blow.
Currently, the standard subordinate electric range cooker has been difficult to meet the "high current, high power, high temperature, high humidity," the power environment.
