How practical is the electric stove? -Alice

December 08, 2021

The diameter and power of the electric stove are different to meet the requirements of different sizes of pots and pans. A new type of electric rice cooker that uses microwave energy to cook food. It is composed of a power transformer, a rectifier, a microwave generator, a magnetron, a transmission wave guide, a stirrer, a fan box, a furnace door, and a controller. See the internal structure of the microwave oven. The main structural components are the waveguide furnace and the door. The wave guide is a rectangular metal tube used to transmit the microwaves emitted by the magnetron. One end of the waveguide is connected to the antenna of the magnetron and the other end is fed from the upper part of the box.

The waveguide also defines the waveform of the electromagnetic field. Most furnaces are metal boxes made of metals such as aluminum or stainless steel. The microwaves in the oven cavity have not been completely absorbed by the food and reach the oven wall, and can be reflected again and penetrate the food to be absorbed. The furnace door is mainly composed of a metal frame and a glass observation window, which is closely connected with the furnace cavity. When in use, the mains power is boosted by a power transformer, after being rectified and filtered by a current stabilizer and a capacitor, it is then converted into direct current to supply the magnetron, and microwaves are generated in the magnetron.

The microwave energy is transmitted through the waveguide, and then reflected by the stirrer to various parts of the oven cavity, and is continuously absorbed by the food. The molecules in the food swing back and forth under the action of the alternating electric field up to hundreds of millions to billions of times per second, that is, the food molecules produce high-oscillation molecular motion and intermolecular friction, so that the food generates enough heat in a short time. The temperature of the food rises rapidly. The power consumption of a microwave oven is only about that of a rice cooker of the same power. There are two general control methods and computer control methods for the electrical control of microwave ovens.

The electric cooker is equipped with a timing device, which can select the cooking time and the appropriate heating power according to different foods. The computer-controlled microwave oven is equipped with a microcomputer, which can make the microwave oven defrost and heat food according to the pre-selected program. The microwave oven should not be burned out when in use, otherwise the magnetron will be damaged because the microwave has nowhere to absorb. The food storage utensils in the cavity must be made of non-metallic materials, such as glass ceramics and high temperature resistant materials.

If you use metal utensils, microwave reflection will interfere with the normal operation of the oven cavity or even cause a high-frequency short circuit, damage the microwave magnetic material and stay away from the microwave, so as not to interfere with the microwave magnetic field. Regularly check the microwave leakage situation and repair the microwave. The power must be cut off. The induction cooker is a new type of electric rice cooker made by the principle of electromagnetic induction heating. It is composed of a high-frequency induction heating coil, that is, an excitation coil high-frequency power conversion device controller and a cooking utensil at the bottom of a ferromagnetic material pot.
