The induction cooker, also known as the induction cooker, is the product of the modern kitchen revolution. It does not require open flame or conductive heating to allow heat to be generated directly at the bottom of the pot, so the thermal efficiency has been greatly improved. It is an energy-efficient kitchen that is completely different from all traditional fire- or fire-free conductive kitchen utensils. The induction cooker is an electric cooking appliance made by the principle of electromagnetic induction heating. It consists of a high-frequency induction heating coil (ie, an excitation coil), a high-frequency power conversion device, a controller, and a ferromagnetic material pot bottom cooker. When in use, an alternating current is introduced into the heating coil, and an alternating magnetic field is generated around the coil. The magnetic field lines of the alternating magnetic field mostly pass through the metal pot body, and a large amount of eddy current is generated in the bottom of the pot, thereby generating heat required for cooking. There is no open flame during the heating process, so it is safe and hygienic.
How to choose the induction cooker
Observe the appearance of the furnace surface
When we purchase the induction cooker, we should pay attention to whether the furnace surface is flat. If the furnace surface is convex or concave or inclined, it will affect the normal generation of thermal efficiency. In addition, the selection of the furnace surface is also very important, and the poor quality of the induction cooker surface is easy to change color, deformation or even crack. At present, the panels used by the major induction cooker brands are mainly Schott, Japan NEG board and domestic common board. At the same time, the domestic board is divided into three grades of ABC. The C-class panel is slightly in heat resistance and is prone to yellow discoloration, and B The edge of the panel is slightly rough and the gloss is not ideal. Key components: The quality of the induction cooker depends on the quality of the high-frequency high-power transistors and ceramic glass-ceramic panels. When purchasing, be sure to purchase a single high-power transistor induction cooker with high speed, high voltage and high current. Because of its good quality, excellent performance, high reliability and damage.
panel
In the core part of the induction cooker, whether the magnetic flux penetrates the top plate of the induction cooker is sufficient, directly reflected in the heating effect of the induction cooker on the pan. On the shelves of the homes of Fulai Electric Appliances, there are many varieties of induction cookers with different texture panels. Supor's shopping guide Tang Qinghua told reporters that at present, most of the induction cookers are sold in the market are microcrystalline panels, in addition to black crystal panels and ceramic panels.
heat sink
Since the induction cooker generates a lot of heat during operation, the function of the built-in fan is very important for the induction cooker. The good induction cooker generally uses an imported DC cooling fan, which has good heat dissipation and low noise, which helps to prolong the service life. The advantages and disadvantages of the radiator can be identified in two ways: when the induction cooker is not working, turn it over and shake it to observe, the fan blade and the shaft, the shaft and the bearing should have no gap and no looseness; when the induction cooker is working In addition to the normal sound of the cooling fan in the furnace, the coils and other parts in the induction cooker must not have sounds such as current hum and vibration. The rotation of the blade should be smooth, without missing or swaying.
reliability
Buying products from well-known manufacturers should also be an important aspect that we should notice when purchasing an induction cooker. Only manufacturers with good reputation, strong strength and quality of products can produce safe, qualified and reliable products that make our daily cooking safer.
Cost-effective modern induction cooker is very powerful, integrating fried, fried, steamed, boiled, fried and many other functions, but remember that not all functions are practical! Everyone should choose their own induction cooker according to their own Actual needs, do not blindly pursue functional completeness.
