The main difference between induction cooker and electric porcelain furnace is the different heating methods. Let's first look at the general principles of the two furnaces. The induction cooker is made according to the principle of electromagnetic induction. The alternating magnetic field generated by the internal coil acts on the iron pan, which makes the bottom of the iron pan produce eddy current effect and makes the iron pan heat itself. Electric porcelain furnace uses nickel-chromium metal heater to generate heat, which is transmitted to the pot through infrared radiation, thus heating the food in the pot. The main differences are as follows.
First, the heating method is different. The induction cooker makes the cooker heat itself, but does not heat itself, with high thermal efficiency, and the highest electrothermal conversion efficiency can reach above 90%. The electric porcelain furnace heats itself and then transfers the heat to the pot. Because of the conduction process, the thermal efficiency is low, only about 60%. From the perspective of saving, induction cookers are more energy-efficient.
Second, pots have different uses. Only good iron cookers from magnetic conductivity can be used on the induction cooker, and other materials will not generate heat. There are many pots that can be used on the electric ceramic stove, and any pot that can be used on the open hearth can be used on the electric ceramic stove. From a practical point of view, the electric porcelain furnace has advantages and can also be used as a barbecue oven.
Third, electromagnetic interference. Because the inside of the induction cooker needs to convert the commercial power into 20KHz high frequency alternating current, it will inevitably cause some pollution to the power grid environment. Ceramic electric furnace is a kind of biased load, which is heated by resistance wire without electromagnetic interference. Now the induction cooker also has an EMC protection module, which is bundled.
Fourth, safety. Because the induction cooker itself does not generate heat, it will not burn even if it is not touched by people. However, because the electric porcelain furnace itself heats up, it will heat up whether it is put in the pot or not, and there will be high temperature residual heat after work, which is easy to form burns. From the safety point of view, the safety of induction cooker is higher.
To sum up, ceramic electric furnace and induction cooker have their own advantages and disadvantages. If the pursuit of functional diversification, you can choose ceramic electric furnace, if the pursuit of safe use, you can choose induction cooker. Of course, this is not absolute. Now many families have these two products to meet different application needs.
Electric porcelain furnace is actually the former electric furnace. It relies on electric heating wires to generate electricity and heat utensils through heat conduction. The only difference is that the heating device is different!
The induction cooker relies on high-frequency alternating electric field to form eddy current inside the metal to generate heat!
The difference between the two is that:
First, the heating principle is different. The ceramic electric furnace heats itself and then conducts it to the heated vessel! The induction cooker itself will not generate heat, but the metal utensils will.
Second, pots and pans have different uses. Electric pottery stoves can use all pots and pans and things that can be used for heating, and induction cookers must use special pots and pans for induction cookers!
Third, the thermal efficiency is different. The electric porcelain furnace adopts conduction mode, so the thermal efficiency is low, while the induction cooker makes the bottom of the pot heat itself, so the thermal efficiency is relatively high!
Fourth, the security is different. The electric porcelain furnace itself is hot and has an open flame. After the pot is removed, the surface temperature of the ceramics is still very high. If you don't pay attention, you will get burned! Because the induction cooker does not generate heat, the self-protection mechanism of the induction cooker will be cut off immediately after the pot is connected, and no collateral damage will be caused!
Fifth, the radiation is different. After all, the electric porcelain furnace is heated by traditional electric heating wire, with low radiation. But if the quality of the induction cooker is poor, there will be high-frequency electromagnetic waves. Although it is also within the national standard, it is still much higher than the ceramic electric furnace!
To sum up, the two are generally different from this. As for which is good, in fact, each has its own advantages and disadvantages, and it is impossible to do it overnight. If you choose, you should decide according to your own use and preferences!
Electric pottery furnace has no electromagnetic radiation, and glass ceramics, aluminum pot pottery pots and casseroles can be used. Even tin foil flowers can be barbecued directly without using a pot. Patients with pacemakers and pregnant women can also use it, but the induction cooker can't pick a pot with too much electromagnetic radiation.
The electric ceramic furnace is an electric furnace, and now everything has to be called a new trick to sell money.
