1. What are the characteristics of the concave bottom induction cooker?
1, all of which are modeled after the previous round bottom pot mode, and some heating areas are added, which is faster, but it also depends on what kind of concave induction cooker you choose. Generally, the original cooking stoves are more affordable than local shopping malls or shops that operate kitchen utensils. Moreover, there are manufacturers with R&D and production strength, and the stoves are well configured and have a long service life. Concave induction cooker is heated more evenly than flat induction cooker.
2. The principle of concave induction cooker is to use magnetic field to induce eddy current heating, and use current 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. Moreover, the electromagnetic waves generated when the induction cooker works are completely absorbed by the shielding layer at the bottom of the coil and the iron pan on the top plate.
3. Heating principle of concave induction cooker, which has electromagnetic induction principle to heat food. The surface of the induction cooker is a heat-resistant ceramic plate. Alternating current generates a magnetic field through a coil under a ceramic plate. When the magnetic lines in the magnetic field pass through the bottom of the iron pot and the stainless steel pot, eddy currents are generated, so that the bottom of the pot heats up rapidly, thus achieving the purpose of heating food.
4. The working link of concave induction cooker is to convert alternating voltage into direct current through rectifier, and then into high-frequency alternating current exceeding audio frequency through high-frequency power conversion device, and add high-frequency alternating current to flat hollow spiral induction heating coil, thus generating high-frequency alternating magnetic field.
5. The ceramic plate with magnetic lines penetrating the furnace is used as a metal pot. Due to electromagnetic induction, there is a strong eddy current in the pot. After the vortex overcomes the internal resistance of the pot, it completes the conversion of electric energy into heat energy, and the Joule heat generated is the heat source of cooking.
Second, how to choose a concave bottom induction cooker?
1. The concave bottom induction cooker adopts a special three-plug power supply, and the electromagnetic field is shunted by the power supply design to completely prevent electromagnetic leakage. Fake inferior flat and concave dual-purpose induction cookers mostly use two plug-in power supplies, which can't prevent electromagnetic leakage. Consumers can directly observe whether the power socket is a three-plug when purchasing.
The most important thing is to consider well-known brands and patented products: there are many fake induction cookers with miscellaneous brands. When purchasing, priority should be given to brands and products with strong technical background and excellent product quality, which can also be obtained at the same time. Dual-use patented induction cooker will become the mainstream of consumption.
3. Forge the triangular metal frame of the inferior flat-concave dual-purpose induction cooker into a fixed bracket, which cannot be lifted. The material is ordinary steel, which is easy to age, rust and heat. Friends who buy can directly observe the tripod when purchasing. The tripod of the flat and concave dual-purpose induction cooker can be lifted freely, and can also be tested with a magnet.
