Induction cooker recommendations for 2024

1. What is an induction cooker and its working principle?

1) Concept

Induction cookers are also called electromagnetic cookers. In 1957, Germany produced the first induction cooker.

2) Working principle

Induction cookers and electromagnetic ranges, as their names suggest, electromagnetic is the main heating method, and electricity is the main source of power. In the experimental classes of compulsory education middle schools or high schools, the electromagnetic induction phenomenon that has been done is the main principle or the main principle of our induction cookers. The working method is to use alternating current to continuously alternating the magnetic field through the metal coil, thereby generating an eddy current inside the metal conductor (a more professional term is Faraday's law of electromagnetic induction), and the eddy current can quickly heat up the conductor according to the thermal effect, thereby achieving The result of heating is the specific working principle of the induction cooker in our daily life.

2. What are the advantages and disadvantages of induction cookers compared with traditional gas stoves?

The reason why the working principle of induction cooker is introduced in detail is to help everyone better feel the huge advantages of induction cooker in modern kitchen equipment.

Compared with traditional gas stoves, there are many aspects to consider. As we all know, induction cookers use electricity as the power source for heating, which means that when using them, there is no need to pay attention to safety issues such as gas leaks, whether the environment is ventilated, regular inspection of pipes, etc.

1) Safety aspects

Induction cookers are safer and more reliable. Because for now, electricity is the safest energy source in family life. As long as the electrical equipment is normal and the circuits are not aging, it can be said that electricity is very safe.

In contrast, with traditional gas stoves, you need to carefully check whether there is any gas leakage when using it, and it is also recommended to ventilate it when used for a long time, because during use, some gas will inevitably be in a state of incomplete combustion and will not be fully burned. Excessive accumulation of completely burned gas will cause gas poisoning, which is very dangerous. (Those who have children at home should pay more attention to safety)

2) Energy consumption

Induction cookers are more energy efficient. Most users believe that gas is cheaper, more cost-effective, and "more energy-saving." Cost-effectiveness and energy saving are not the same. Cost-effectiveness is because of gas. The industry chain is old and the cost of fuel production is low, which makes the price of gas low, which results in To make it more cost-effective, in fact, from the perspective of heat consumption, gas stoves belong to open flame cooking. During the process of combustion and heat generation, most of the heat will be emitted with the air, and the heat transferred to the pot will actually attenuate. Many scientific experiments have proven that the gas heating efficiency is far less than 40% of the combustion energy, which causes more waste of energy. However, induction cookers rely on electromagnetic heating to conduct heat in conductors and can be said to lose very little heat energy. Although the price of electricity is more expensive in the short term, in the long run, induction cookers can save more energy.

3) Pollution

Induction cookers are cleaner and more environmentally friendly. Gas stoves have several major pollution problems.

(1) Gas stoves are noisier than induction cookers. The bigger the pot, the louder the noise. This is why the chefs in restaurants always need to shout loudly. This is also true for home use. It is often difficult to communicate while cooking. .

(2) Housewives and cooks are very troubled by the large amount of oil smoke. Because there is still a lot of oil smoke and dust produced by cooking over an open flame, the kitchen is often dark and dirty over the years. Cleaning up the oil smoke is particularly time-consuming and laborious. It is also difficult to completely inhale the exhaust hood.

(3) When cooking in summer, gas stoves are extremely "hot". The heat of the air itself is very hot. Coupled with the heat emitted by the gas, it is really unbearable.

Induction cookers do not have the above problems. First of all, the latest induction cookers can be said to be almost silent and have no noise pollution; non-open flame heating greatly reduces the emission of oil smoke; and the last one is the advantage of induction cookers. You can hardly feel the heating of the kitchen.

The fly in the ointment is that due to the working principle of electromagnetic efficiency, the radiation of induction cookers is still larger than that of traditional gas stoves. However, if the induction cooker is used for dozens of hours a day, the radiation does not pose a threat to health. Of course, no one will "hold the induction cooker." sleep".

4) Ease of use

Induction cookers are more universal and easier to use. "Whether the food is cooked well or not, the heat is very important." Heat is one of the key factors when cooking, but it is also where many people have difficulties. Ingredients can be measured in grams, etc., but the size of the traditional gas stove fire is completely different. Method quantification.

The emergence of induction cookers allows the heat to be quantified. With the update and iteration of product technology, some have heat and power options such as "hot pot, frying, soup", etc., allowing the cooking heat to be quantified and better controlled, allowing cooking and The spread of cooking techniques is more visible.

In addition, there is another more important thing. In modern society, renting a house, a low-rent house, or even a new house have become commonplace. Once a traditional gas stove is fixed and installed, it becomes very troublesome to replace it as the place of residence changes. This problem is also a disadvantage that discourages young people who go out to work and pursue their dreams. Moreover, it is difficult to disassemble and clean completely. On the contrary, induction cookers are generally small in size and more portable. They are very convenient to move and clean. of.

However, because it is an electric energy source, this also limits the maximum output power of the induction cooker. It cannot have a high upper limit like gas. This is why restaurants often do not use induction cookers and choose gas stoves. However, from the perspective of home cooking, heat, High firepower limit, very high gas stove.

To sum up, it can be seen that compared with traditional gas stoves, induction cookers have far more advantages than disadvantages.

3. Who is suitable for buying an induction cooker?

Although the advantages of induction cookers are very obvious, they are not perfect. Although they are very universal, there are also people who are suitable and unsuitable.

Suitable for people, in a broad sense, because it is convenient, simple and safe to use, and can be used well by people who often cook.

However, in a narrow sense, due to the upper limit of heat and limited operability, "gourmets" and "professional chefs" who have very high requirements for food are not applicable.

4. Key points for purchasing induction cooker

1) Look at the rated power

The electric power of the induction cooker is the source of energy supply, and the rated power determines the most critical heating capacity. In layman's terms, it is the speed at which our food can be cooked by this pot. When choosing, first look at the power.

Judging from the large number of products from these five major brands, as well as many small brands, the mainstream power range is 120W-2200W. The rated power of the product is generally marked as 2200W, which is the maximum firepower. Of course, there are also some 1800W products, more strictly speaking. , the range of 1600W-2200W belongs to the mainstream product power.

I often see many friends saying that the rated power of 2100W or even 2200W is too large, which is actually a waste. However, anyone who has studied physics should understand that the higher the rated power, the higher the heating efficiency, which means that the heating is faster. If you are just heating water, there may not be much difference between 1600W and 2200W, because the boiling point of water is easy to reach under normal conditions, but if you use the same two models to eat hot pot, there may be a difference between the lowest gear and the highest gear. , so here, it is strongly recommended that starting from 2100W is also the mainstream of market products with moderate price. Generally, the price of products above 2200W will be slightly higher, which may satisfy users who have higher pursuit of cooking.

2) Look at the energy efficiency level

We need to first understand what the equivalent level is. The so-called energy efficiency level refers to the national mandatory grading system for the energy efficiency of household appliances, which can also be said to be a grading method.

Level 1 means that the product's energy efficiency has reached the international advanced level and has the lowest energy consumption; Level 2 means that the product is relatively energy efficient; Level 3 means that the product's energy efficiency is the average level of the Chinese market; Level 4 means that the product's energy efficiency is lower than the market average; Level 1 5 is the product market access indicator. Products below this level are not allowed to be produced and sold.

The lower the energy efficiency level, the more energy is saved. For us users, it means more electricity. When it comes to large appliances, many users pay more attention to the energy efficiency level, because "big size consumes more power". In fact, this idea is not entirely correct. Let's give a popular example. , the refrigerator basically runs 24 hours a day, and the induction cooker and refrigerator are not cooling at full power most of the time, that is, they are not in the most power-consuming mode. There is only one time in a year that we can open the refrigerator to "release air conditioning", and the equivalent level of one day is 1 The power consumption of a refrigerator is basically around 0.6 degrees, but an induction cooker with an energy efficiency level of 3 and a rated power of about 2100W can cook hot pot at full power for 1 hour to 1.5 hours. The basic power consumption is more than 2 degrees, and the induction cooker accumulates over the years. The full power time is much longer than that of a refrigerator.

This comparison shows the importance of energy efficiency level, so induction cookers should pay more attention to energy efficiency level. Currently, the mainstream induction cooker energy efficiency level on the market is level 3. If the induction cooker is higher than level 3 energy efficiency, it is not recommended to choose it.

3) Look at the firepower level

Firepower gears are what we often call several modes that control different firepowers through different gears. The biggest weakness of traditional gas stoves is that "moderate firepower" cannot be quantified. Since it is the advantage of induction cookers, we should consider it when choosing. Pay great attention to this item.

Judging from several major brands, the generally mainstream gears in the market range from 4th gear to 10th gear, mainly showing 4th gear, 6th gear, 8th gear, 9th gear, and 10th gear. , if you encounter an induction cooker with gears below 4, please rule it out directly. (Belongs to the traditional electric wok series)

The more gears, the more precise the firepower can be controlled during cooking. Let’s take an example of Brother Hong’s daily cooking: Japanese omelet, which pays attention to rolling and frying constantly. I hope it will be faster when the oil is hot. , but the eggs are easy to burn if they are too hot after being placed in the pot, so usually reduce one or two gears. When the eggs are basically solidified, you need to increase the gear to quickly cook them and roll them. At this time, you need to reduce more gears and then adjust the high gear to the low gear. Position cycle, if I use the 4th gear, there is a high probability that the omelet will have cooked noodles and uncooked noodles at the same time. This means that the gears are few and difficult to control, but the 10th gear is often very competent, so 8 is usually recommended. - An induction cooker with 10 gears can control the heat more precisely, but too many gears are not good, because the difficulty of control increases with more gears, so 8-10 gears are the best.

4) Check the waterproof function

"How can you not have wet shoes when you often walk by the river?" When cooking, there is always soup and water spilling out, and sometimes water may overflow when cooking. Since it is an electrical appliance, it must test the waterproof function. This is when choosing a product. At this time, we noticed several major waterproof levels and methods.

First check whether it has IPX4 waterproof rating;

The second product introduces whether there is an anti-overflow tank design to protect the components to the maximum extent, and whether there is a water baffle installed under the surface plate;

The third is whether the core components have a waterproof design (such as a waterproof wall);

5) Look at the specifications and dimensions

Before purchasing an induction cooker, measure the size of the pot in your home before purchasing a matching induction cooker. Generally speaking, the higher the price, the larger the size of the induction cooker.

6) Security protection function

Security protection functions mainly come in the following two forms:

The first is overheating and power-off protection, that is, when the pot is overheated when dry-cooking, the induction cooker passes the temperature detection to avoid fire;

The second is intelligent detection, which detects different pots, weights and temperatures at the same time. This is relatively higher-end and safer.

Summarize

The main difference between different price ranges is in panel size and variable frequency constant temperature technology. People with space and budget are recommended to choose a large-sized induction cooker in one step.

That’s all the guide for purchasing induction cookers, thank yo
