First, the difference between a microwave oven and an induction cooker
1, electric ceramic furnace, convection oven: the heating element is heated by heating, the heat source is outside the heating object, and the object is heated by infrared radiation. The heating object can be various temperature-resistant materials, and the heating range is wide. Will not produce harmful electromagnetic radiation. Thermal efficiency is related to the heat transfer process and sensitive to the color of the heating body. Due to the loss of transfer process, the efficiency is slightly worse than that of electric furnace. The heating diameter is smaller than that of the induction cooker, and the heating diameter of the single-turn electric ceramic furnace is 17.5cm.
2. The double coil is 20.5CM, and the heating diameter of convection oven is about 18CM. Both furnaces have relatively large residual heat, which takes a long time to cool. These two furnaces are resistive loads, so it is easy to control the power, and it can be easily controlled from 0 to the maximum power. Convection ovens consist of two lamps (some with four lamps) and a reflector. The uniformity of heat source is relatively poor. The resistance of electric ceramic furnace is heated by corrugated coil, so the uniformity of heat source is better. The number of control gears: 5 to 30 for electric ceramic furnaces and 5 to 9 and 18 for convection ovens. It can be used directly in the preheating stage.
3, induction cooker: the heating principle is that the electromagnetic field generates eddy current heating inside the heated object. The heating element itself is the heating object. The heating object itself is too big or too small to work effectively, so only ferromagnetic heating objects can be selected. There is a certain amount of harmful electromagnetic radiation, which can be reduced or basically eliminated. The heating object itself generates heat, so the thermal efficiency is relatively high. The heating area is relatively large, generally reaching a diameter of 26CM.
Second, how to choose an induction cooker
1, first look at whether the panel is flat, convex or inclined, and choose smooth and undamaged; Look at the color of the panel. Black German glass ceramic panel and smooth pure white Japanese NEG ceramic panel are both high-quality panels. Used by famous factories and large factories; Domestic grade A and grade B boards are also white, but the edge of grade B board is rough and there is no grade A smoothness. C-grade boards are prone to yellowing and discoloration, and manufacturers usually print patterns on them. Try to buy imported panels or domestic A-class panels.
2. Then look at the cooling fan at the bottom and choose the product with a larger diagonal size. It is best to use magnetic levitation, hydraulic or nano-ceramic fans. If it can be removed, please press the fan blade by hand. It can be pressed about 2mm for magnetic levitation. Otherwise, this is not the case. Please refer to the shopping guide to see if you can confirm the type and brand of cooling fan. For example, if you use AVC and other international manufacturers, the manufacturers are willing to invest the cost. Heat dissipation efficiency will affect the service life of internal components, and a good cooling fan can reduce the noise during normal operation. 3.3
3. Look at the power plug. You should buy a three-pin power plug product. Then enter the product test. Product testing is divided into five steps:
