The principle of ceramic electric stove is simply the electric stove we used at home when we were young-what? You are still young. Haven't you heard of it? This is the thing ▼
After electrifying, current flows in the resistance wire. Because the current has a thermal effect, the resistance wire heats up. Ceramic electric furnace is an improvement of this kind of electric furnace. The original resistance wire is replaced by nickel-chromium metal material, and it is closed.
The biggest problem of the electric furnace just mentioned is that the resistance wire is exposed. This is equivalent to an open flame, on the one hand, heat leaks out and efficiency is low; On the other hand, it is dangerous and easy to catch fire. The electric porcelain furnace closes the heating plate, so there is no such trouble.
The biggest disadvantage of the induction cooker is that it needs to pick the pot-the working principle of the induction cooker is to use the magnetic pot to cut the magnetic induction line emitted from the inside, so the ordinary pot cannot be heated on the induction cooker. The electric porcelain furnace has nothing to do with the magnetic field at all, and it is completely heated by resistance, so naturally there is no such trouble.
As a result, two characteristics of the electric pottery furnace appeared: nameless fire, not picking pots!
Other differences are not obvious. For example, some merchants say that ceramic furnaces have more accurate temperature control and more uniform heating-cheap induction cookers do have these two problems, but induction cookers with more than 200 yuan are basically double coils, which can also solve these two problems.
Some merchants also say that the electric porcelain furnace has a good insulation effect-in fact, it is because the electric porcelain furnace uses the surface to conduct heat directly, and there is still residual temperature on the surface after it is closed. The induction cooker is heated by magnetic field, which only heats the pot and does not heat the induction cooker itself. The so-called "good heat preservation effect" also has disadvantages, that is, the surface temperature of the electric porcelain furnace just closed is too high, which is easy to burn.
This is the difference between the two. If only practicality is considered, the electric porcelain furnace is slightly better. However, the price of ceramic electric stove is at least twice as high as that of induction cooker, and users can decide how to choose.
According to my previous test experience in electrical appliance factory, I personally think that induction cookers are safer. Before answering this question, first understand the principle, advantages and disadvantages of induction cooker!
Induction cooker, also known as induction cooker, is the product of modern kitchen revolution. It does not need naked flame or conduction heating, but allows heat to be generated directly at the bottom of the pot, so the thermal efficiency is greatly improved, and it is an efficient and energy-saving kitchen appliance. Its definition is very profound and complicated. I can summarize it in one sentence. It generates heat by cutting with a magnetic field. The pot used in the induction cooker must be iron or gold-containing copper (remember that there is a stainless iron pot, which can't be used in the induction cooker), and its high permeability enhances the magnetic induction, thus greatly improving the efficiency of electromagnetic heat conversion.
Advantages of induction cooker: 1. The efficiency of heat conversion by magnetic field is improved, thus saving electric energy. 2. The place with higher temperature is the bottom of the pot, and the surrounding temperature is relatively low, so it is not easy to burn people and reduce heat loss.
Disadvantages of induction cooker: If the quality of induction cooker is not very good, electromagnetic radiation will do great harm to people, so it is recommended to choose a brand and a better pot when choosing induction cooker.
The principle of ceramic electric furnace is the same as that of commonly used electric heating wire. Controlled by electronic board (or controller) and thermostat, with a piece of glass on the surface. When working, the surface temperature of the glass reaches 700-800℃, and then the food is heated through the bottom of the pot, so as to achieve the purpose of cooking food.
Advantages: no electromagnetic radiation, harmless to human body.
Disadvantages: 1 Because food is heated by heat transfer, the heating efficiency is not very high and it consumes a little electricity. 2. Because the temperature inside and on the surface of the furnace is very high, the temperature line inside will age for a long time, and the temperature can't be controlled. 3. If the room temperature is cold, the glass on the surface is easy to deform or explode when it is hot or cold, so the requirements for the glass on the surface are relatively high, so you should pay attention when purchasing the electric porcelain furnace. 4. Because the surface temperature is relatively high, it will be hot in summer, and it is easy to burn people if you are not careful.
After reading the above introduction, if you still want to buy an electric ceramic stove, I suggest you buy a big brand, not a small brand. Big brands are strict about quality and certification, so it will be safer to use.
Ok, I'm Digital Xiao Huang. I've studied electrical appliances and digital. I hope everyone will pay attention to me, and I will do my best to help you. If you have different opinions, please leave a message in the comments below!
I really don't recommend ceramic electric stoves. I was out of my mind and bought one. I regret it! I gave it away a long time ago. This thing is great. In fact, it feels like an old electric furnace wire with a shell! That thermal efficiency, the same power induction cooker can throw him a few blocks away! Want to cook? It's all stewed, so wait patiently for it to cook.
The induction cooker has the functions of fast heating, energy saving, environmental protection, no fire, convenient use, accurate temperature control, high safety, easy cleaning and "frying, boiling, stewing, steaming and rinsing".
The principle of the induction cooker is that alternating current generates a magnetic field through the coil. When the magnetic lines in the magnetic field pass through the bottom of the pot, they generate eddy current (that is, the principle of * * * vibration), which makes the bottom of the pot heat up rapidly, thus achieving the purpose of heating food.
Although induction cookers have many advantages, they also have obvious disadvantages: picking pots, heating quickly, drying empty pots easily, even burning food sometimes, high failure probability, troublesome maintenance, inconvenient cooking in flat pots, many induction cookers that do not meet the national standard are not powerful enough in actual working power (energy efficiency is not up to standard), electromagnetic radiation (small, about 50cm away from the stove can be basically ignored) and so on.
The induction cooker can't work without a porcelain pot. The electric ceramic furnace can generate heat after being electrified, and will not pick the pot.
In addition to frying, frying, hot pot, slow stew, appointment and other functions. The electric pottery stove can also be equipped with a barbecue grill for indoor barbecue or iron plate, and can also be used as a heating tool in winter!
The disadvantages of electric porcelain furnace are also obvious: the heating speed is not as fast as that of induction cooker and the thermal efficiency is low. After each use, the panel needs to be cooled for a long time, which gives people a hot and dazzling feeling when used in summer.
At present, there are many big brands on the market, all of which have launched their own brands of induction cookers and ceramic stoves. I hope you will have a new understanding through my introduction. It is recommended to read the product manual and precautions carefully when purchasing!
Easy to use, but too dangerous.
The furnace wire will be deformed and the pot will leak electricity.
Cooking inevitably leads to vibration and leakage, and both pots and shovels have electricity, which leads to electric shock.
I once spilled uncooked vegetables all over the floor.
As for maintenance, I feel that electric porcelain stoves have no brand effect, and most of them are unheard of groceries. Because the electric heating tube is bare, the heat radiates to the inner cavity, and the miscellaneous shell is made of inferior plastic, which will be deformed and brittle soon after use.
Both induction cooker and electric ceramic stove have been used. I don't think it makes any difference. They don't work! The biggest disadvantage is uneven heating, charred bottom and bad sides!
Electric furnace wire is a backward and obsolete product with short service life and high power consumption. Plugs and sockets burn easily, and everyone knows what they have used. Therefore, the electric porcelain furnace just changed its packaging, and the cost was very low. People who don't know electrical appliances are cheated. The induction cooker is the product of the development of science and technology, which initially replaced the ceramic electric stove. China people just like to cheat people with cleverness. That's awesome.
Don't listen to nonsense. The so-called electric porcelain furnace is the former electric furnace! Add the circuit to control the firepower and add the panel (too safe). This kind of furnace (electric furnace) consumes electricity and is inefficient! The advantage is that any pot can be used, just use an electric stove. The induction cooker picks pots, but it is determined by electromagnetic characteristics, but the efficiency is much higher. Quality is very important, brand model is very important! Those advertisements that can't be hearsay have their own merits. I hope you can understand clearly before buying.
No, no right to speak! Recently, I bought an electric ceramic stove online, which cost 238 yuan. There is no advantage except that I don't pick the pot. First of all, the thermal efficiency is very low. If I add it to 2200W, it looks red and it's not cooked well. There is not much heat, and I dare not go to the induction cooker at 280 degrees! If the heating is not fast, the residual temperature of electricity will cool down in ten minutes, wasting energy! Don't compare the heat with the gas stove! In short, hot rice and porridge can be used. Don't use it reluctantly. Forget the rest! Regret buying it!
