First, briefly understand the heating working principle of induction cooker and electric ceramic furnace. The working principle of induction cooker is to generate magnetic field through coil. When the magnetic force in the magnetic field passes through the bottom of the iron-containing pot, it will produce countless tiny eddy currents, which will make the pot itself heat at high speed, and then heat the food in the pot. The working principle of electric porcelain furnace is somewhat similar to that of the early ones? Electric stove? The alloy wire is electrified and heated to generate thermal radiation (manufacturers promote infrared rays, and the thermal radiation mainly depends on visible light and infrared rays with longer wavelength), so that the pot body is heated.

(1) take the same water to prevent the same pot. Before the test, be sure to turn on the cold water of the induction cooker (electric porcelain furnace) and turn on the power supply to the maximum. ③ Record the instantaneous power consumption of the circuit, and record the boiling time when water boils. ④ Record the power consumption during the boiling time. According to the test results, the ceramic electric furnace is basically in heating performance. A complete failure? . The boiling time of electric porcelain furnace is nearly 4 minutes longer than that of induction cooker, accounting for more than 82%. The power consumption of electric porcelain furnace is 0.2 14 degrees, which is about 1.7 times that of induction cooker. The reason why there is such a big difference is that they work in different principles. The magnetic field generated by the induction cooker makes the pot itself generate heat. This process has high heat conversion efficiency and there will be no other energy loss in the middle. Because the electric porcelain furnace is a pure resistance circuit, the heat energy emitted by the alloy heating wire can not be completely absorbed by the bottom of the pot, the heating process will become relatively slow, and the power consumption will increase accordingly. Test results: electric ceramic stove VS induction cooker who is the hot pot weapon? According to the test results, the surface electromagnetic radiation value of electric porcelain furnace is only 1.373 compared with that of induction cooker. T is one-tenth of the radiation of induction cooker, but its radiation standard is still difficult to reach 0 radiation due to circuit work and other reasons. In fact, it is difficult to achieve zero radiation in the indoor environment because there are many electrical appliances and radio waves everywhere. In terms of noise performance, the working noise of the electric porcelain furnace is 54.8 decibels, which is quieter than the induction cooker because there is no need to switch frequencies during use. At present, there is no EMC standard for induction cookers in China, and the industry reference value is 3-6? T. However, electromagnetic radiation is very easy to decay, and it is precisely for this reason that the test results at different distances are very different. Therefore, users don't have to worry about electromagnetic radiation in the actual use process, and mobile phones and computers are the main radiation sources. In contrast, the use time of induction cooker is much shorter, and it is not for personal use. In addition to some differences in hard parameters, the use habits of induction cookers and electric ceramic stoves are also essentially different. What kind of usage habits will these differences cause to users?

Because of the working principle of induction cooker, it is necessary to use iron pot when using induction cooker. In fact, the induction cooker is very picky about the bottom of the metal pot. The container used by the author to hold water was originally used to test boiling water, but the induction cooker picked the pot and had to try to test it with a wok. In contrast, the electric ceramic furnace has no problem of picking pots at all. Because it is a heat source, all the pots you can think of can be used directly. Ceramic pots, glass pots and teapots are not a problem. You can even barbecue directly on the electric ceramic stove with an iron plate or barbecue grill, and you can completely ignore the problem of picking pots.

This has both advantages and disadvantages. When the induction cooker is used, it only heats the bottom of the pot, but after the pot is taken away, the surface of the panel is only the residual temperature left by the bottom of the pot, and fingers can still touch the panel briefly. Don't worry about burns after use. Ceramic electric furnace is a spontaneous heat source. Look at the bright red heating wire after use. You can feel the obvious heat source 30cm away from the panel. Who dares to raise their hands at this time? In order to increase the effect, the author dropped a spoonful of cold water on the panel, and the water boiled as soon as it touched the panel, and the temperature of the panel at that time far exceeded 100℃. The ceramic electric stove can not be moved until it is placed for at least 20 minutes after use, so as not to burn the skin at high temperature. Because it is a spontaneous heat body, the electric porcelain furnace needs to dissipate heat for a longer time. After the electric porcelain furnace is closed, the fan of the electric porcelain furnace is still working to assist the internal heat dissipation of the electric porcelain furnace, and the whole process lasts for 20 minutes. Although the induction cooker needs to dissipate heat after it is turned off, this process often takes only 5 minutes.

Honestly, see? Keep warm? This function, the author also feels a bit ridiculous. Is this an additional function of the product? The principle of electric porcelain furnace is too close to the previous electric furnace, and even its functions are so similar. Pottery stoves can keep warm, so what do you think of electric heaters and electric heaters?

Through the performance comparison between the above electric porcelain furnace and induction cooker, I hope you can meet some difficulties when purchasing, and I hope you can get some help after reading it.
