It is more cost-effective to use an electromagnetic cooker than a gas cooker, because 1. Electromagnetic cookers are safe and convenient. 2. From the economic point of view, when gas was sold to 41 yuan, the electricity price was 1.57 yuan /KWh, and the consumption amount was equal. Now the gas has risen to 71 yuan, but the electricity price has dropped to 1.4983 yuan, so it is cheaper to use an electromagnetic cooker than gas, so it is more cost-effective to use an electromagnetic cooker than a gas cooker.

The induction cooker, also known as the electromagnetic cooker, is the product of modern kitchen revolution. It allows heat to be generated directly at the bottom of the pot without naked flame or conductive heating, so the thermal efficiency has been greatly improved. It is an efficient and energy-saving kitchen utensil, which is completely different from all traditional kitchen utensils with or without fire conduction heating. Induction cooker is an electric cooking appliance made by electromagnetic induction heating principle. It consists of high-frequency induction heating coil (i.e. excitation coil), high-frequency power conversion device, controller and ferromagnetic pot bottom cooker. When in use, alternating current is introduced into the heating coil, and an alternating magnetic field is generated around the coil. Most of the magnetic lines of the alternating magnetic field pass through the metal pot body, and a large number of eddy currents are generated in the pot bottom, thus generating heat needed for cooking. There is no open flame in the heating process, so it is safe and hygienic.

Main features of this paragraph

1. The induction cooker uses a coil disc to generate a high-frequency (21~25KHZ) alternating magnetic field under the action of a control circuit, which generates a large number of dense eddy currents through a magnetic conductivity (iron) cooker, and the induction current is converted into heat to heat food, so the energy efficiency is extremely high.

2. Be sure to use iron, special stainless steel or iron-baked enamel pans, and the diameter of the pan bottom should be 1.2 ~ 26 cm.

3. The induction cooker is equipped with a temperature controller, which can prevent overheating, save electricity and be safe.
