The development status of induction cooker

Looking at the development status of domestic induction cookers, from a technical point of view, there are mainly the following aspects:

Presenting "a hundred schools of thought contend"

The development of the domestic induction cooker market is relatively chaotic. According to the survey, in 2001, there were less than 100 domestic induction cooker manufacturers, and there were also very few manufacturers of electronic components and supporting products related to the induction cooker. , And in the shopping malls, there are also forty or fifty in total, and there are countless manufacturers that process and produce induction cooker spare parts.

The appearance design is "a hundred flowers blooming", and the structural performance needs to be improved

It is no exaggeration to say that in the domestic induction cooker market, the design of each appearance is "a hundred flowers blooming". If you go to any store, you will find that the appearance design of the induction cooker is really colorful, from the color matching to the design of the control interface. If it does not reflect its own personality, it is very different from the mature market structure of induction cookers abroad. However, in such a rich design, few brands can achieve the level of excellent structure and performance. Most brands package the induction cooker into ever-changing styles, but the multi-structure design is not ideal from a technical point of view. .

Parts setting "uneven layers"

Relatively mature, the main parts of the induction cooker will definitely use the parts with superior performance and strong compatibility, and the chips are used, Toshiba, Taiwan and South Korea, but when dismantling the induction cookers of various brands, you will find that the main components are really uneven. Some even do not even have manufacturers, doing so will inevitably hinder the normal development of the induction cooker.

Technological 'stagnation'

Since the domestic induction cooker has not yet fully entered the mature stage, an abnormal price war has begun, which has led to good technical research and focus on cost reduction, resulting in the emergence of a technically no dominant overlord for a while. . Foreign investment in product research and development in this growth period ranges from 15% to 30% of total sales, but few domestic induction cooker products can invest millions in research and development.

The development trend of induction cooker

1. HI electric rice cooker: IH electric rice cooker is a combination of electromagnetic induction heating principle and fuzzy control technology. Its cooking effect is very ideal, and it has become the mainstream product of electric rice cooker in Japan.

2. Electromagnetic water heater: The electromagnetic water heater uses the principle of electromagnetic induction heating to heat water. Its outstanding advantage is that it realizes the isolation of water and electricity, and solves the leakage protection problem of electric water heaters in principle.

3. Double-headed induction cooker: Double-headed induction cooker is an induction cooker with two heating units. The two units can work independently of each other, and its technical difficulty is greater than that of a single-headed induction cooker. Design measures such as anti-interference, noise and electromagnetic radiation need to be strengthen.

4. Higher frequency induction cooker that can heat aluminum pots: Since the resistivity of aluminum is only 1/20 to 1/50 of that of iron, when the frequency exceeds 50KHz, the aluminum pot can also be heated. Japan has developed this kind of product. There is no such product in China.
