1. The difference between a multi-purpose pot and an induction cooker
Which one is better, a multi-purpose pot or an induction cooker? Let me compare the working principle, functionality, practicability and advantages of the two. The shortcomings are analyzed for your reference:
1. Comparison of the working principles of the multi-purpose pot and the induction cooker
Both the multi-purpose pot and the induction cooker are modern kitchens The products of the revolution can directly generate heat at the bottom of the pot without an open flame, and the thermal efficiency has been greatly improved. It is a new type of kitchen utensils with high efficiency and energy saving.
Induction cooker, as the name suggests, uses the principle of high-frequency electromagnetic induction to make the heating coil generate heat, and controls the high-frequency power conversion device through the controller. food.
The multi-purpose pot (multi-function electric heating pot) uses multiple independent electric heating tubes to directly heat the stainless steel pot body that is sealed and connected to a bottom heating plate through a special process. The difference between the two is that one is heated by electromagnetic heating, and the other is heated by converting electrical energy into thermal energy.
2. Functional comparison of multi-purpose pot and induction cooker
The multi-purpose pot can fry, fry, steam, boil, and fry food , stuffy, stew, rinse, bake, roast, can be described as decathlon, and the function of induction cooker is limited to a few of them, such as frying, frying, rinse. Therefore, in terms of functionality, the induction cooker is at a disadvantage.
In addition, the functionality of the induction cooker also depends on the corresponding pots. Due to the principle of the induction cooker, the pots used on the induction cooker can only generate heat at the bottom of the pot. Iron pans, for traditional wok or steamer (aluminum pan), either have low thermal efficiency, heat unevenly, and cannot be used at all. Therefore, as an electric frying pan and an electric steamer, whether the induction cooker is competent depends on the pot, and the induction cooker picks the pot, which is a well-known disadvantage. And the multi-purpose multi-purpose pot does not need to consider this problem, because the multi-purpose pot and the heating device are integrated with the pot, stainless steel has good thermal conductivity, does not generate thermal expansion, and the pot body heats evenly, no matter what cooking technology is used. , can be easily achieved. It can be seen that in terms of functionality, the multi-functional multi-purpose pot has obvious advantages.
3. Performance comparison between multi-function pot and induction cooker
Many induction cooker manufacturers claim that induction cooker has high thermal efficiency. Effective usage is the correct measure. As we all know, the induction cooker picks the pot, and the heating part of the pan used is only the part of the bottom of the pot and the area of the magnetic induction coil that generates heat. Under the same power state, it takes 3 minutes to fry the same amount of food with a multi-purpose pot , and the induction cooker needs 6-8 minutes or even longer. It is self-evident that the conversion rate is higher. The fundamental reason is that although the induction cooker has high thermal efficiency, the conversion rate of the pot is too low due to the selection of the pot. The thermal efficiency of the pot is high.
4. Comparison of other aspects of multi-functional multi-purpose pot and induction cooker
1) Safety comparison. Although the multi-purpose multi-purpose pot is a direct-use electric heating method, the safety may be slightly inferior to that of the induction cooker, but the national mandatory 3C certification makes up for this shortcoming, ensuring that each multi-purpose pot product will not affect the product. damage to the human body. Moreover, all multi-functional multi-purpose pot products use three-phase wiring plugs. It is clearly stipulated in the manual that they must be connected to a power supply with a ground wire to work normally, which greatly ensures the safety of users’ electricity consumption, while induction cookers generally use two If there is a leakage or failure of the induction cooker, it is easy to cause an accident.
2) Comparison of maintenance and service life. The maintenance of the multi-purpose pot is simple. After use, when the temperature of the pot body returns to normal temperature, just wipe it with a clean rag and keep the plug clean; and the base of the induction cooker is prone to dirt, which is very difficult to wipe. It is difficult, and cannot be wiped with hard things, otherwise it will cause damage to the electromagnetic induction coil of the induction cooker. From a cleaning perspective, a multi-purpose pot is easier to maintain. Looking at the service life, the high-frequency electromagnetic induction device of the induction cooker generally has a service life of about 3 years, and the efficiency will be reduced, aging, and the magnetic induction part of the chassis will be severely worn and scrapped, and it cannot be used. Years must be eliminated; and the multi-functional electric heating cooker, due to the use of electric heating tubes, generally has a lifespan of about ten years before being eliminated.
3) Price comparison. The price of the induction cooker generally ranges from 200~300 yuan, but the induction cooker also needs to be equipped with a good quality pan, the price of the pot is generally more than 200 yuan, and in order to meet various needs, it may be equipped with a variety of two There are more than one type of cookware. Taken together, the price of a set of integrated induction cooker is more than 600 yuan, while the price of a multi-functional electric heating cooker is generally around 300~500 yuan, and a multi-purpose cooker does not need to purchase cookware. , its own food-grade high-quality stainless steel cookware, hygienic, clean, beautiful appearance, luxurious and generous. In addition, make a trade-off between time and electricity consumption. In terms of power, the induction cooker is similar to the multi-functional electric heating pot, which is basically about 2000W. It cooks 4 dishes a day. It takes more than 30 minutes, and the pot needs to be replaced in the middle, which takes longer. In addition, during the cooking process, the induction cooker needs to frequently turn the pan to ensure even heating, and the multi-purpose pot only needs to be turned several times. Make sure the fried vegetables are evenly heated.
Based on the above comparison, the advantages of the multi-functional multi-purpose pot compared with the induction cooker are very obvious.
Second, which is the higher thermal efficiency of the multi-purpose pot and the induction cooker
The multi-purpose pot and the induction cooker are both new types of kitchen cookware. The focus issues are discussed in detail here.
The multi-purpose pot adopts the principle of electrothermal conversion, and the stainless steel pot body is heated by the electric heating tube to generate heat energy to heat the food, while the induction cooker controls the high-frequency power conversion device through the controller to make the ferromagnetic material at the bottom of the pot and the The bottom of the metal pan creates eddy heat that heats the food. On the surface, it seems that the induction cooker directly heats the food by converting the heat of electric energy, while the multi-purpose pot heats the pot body through the heating tube, and then uses the heat of the pot body to cook the food. From the perspective of the efficiency of electric energy conversion, the induction cooker should be It is higher than the multi-purpose pot, but everyone has overlooked a problem, that is, the part of the induction cooker that generates heat energy can only be the bottom of the pot and the part equal to the area of the ferromagnetic material, and the electromagnetic effect has certain requirements on the pot, which must be in contact with the induction cooker. Only part of it will generate heat, while the multi-purpose pot is the whole pot body. In other words, the heat converted from electrical energy at the same time, to be converted to the temperature of the food, mainly depends on the area in contact with the food. We all know that the induction cooker must use a flat pan, and the multi-purpose pot uses a curved bottom, which greatly improves the contact area with the food.
Although the electric energy conversion efficiency of the multi-purpose pot is not as high as that of the induction cooker, the heat received by the food per unit time is indeed provided by the multi-purpose pot. Naturally, the multi-purpose pot is naturally faster than the induction cooker. The thermal efficiency It is also higher than the induction cooker, because, in order to make up for this deficiency, the induction cooker only increases the area of the ferromagnetic material and increases the power of the high-frequency induction part, which is why the power of the induction cooker is higher than that of the multi-purpose pot, but after all, the induction cooker is a It is a kind of small kitchen appliance product, so its power cannot be too high, which also determines that the thermal efficiency of the multi-purpose pot is still higher than that of the induction cooker, and the multi-purpose pot is heated by the whole pot body, which is evenly heated, and the effect of cooking food is better than that of the induction cooker. many.
