Detailed Description
Embodiments of the intelligent horizontal microwave oven of the present invention will be described in detail with reference to the accompanying drawings.
Microwave ovens are cooking appliances that heat themselves by absorbing microwave energy in a microwave field. Microwave generated by microwave generator of microwave oven creates microwave electric field in microwave oven cavity, and adopts certain measures to make the microwave electric field be uniformly distributed in the oven cavity as far as possible, and the food can be placed in the microwave electric field, and the control centre can be used for controlling cooking time and microwave electric field intensity so as to implement various cooking processes.
Generally, microwaves are high-frequency electromagnetic waves, do not generate heat, and are generated everywhere in universe and nature, but the microwaves in nature exist, and are not concentrated, so that food cannot be heated. The microwave oven utilizes the magnetron inside it to convert the electric energy into microwave, which penetrates the food at the oscillation frequency of 2450MHz, when the microwave is absorbed by the food, the polar molecules (such as water, fat, protein, sugar, etc.) in the food are attracted to oscillate rapidly at the speed of 24 hundred million and 5 million times per second, and the macroscopic expression of the oscillation is that the food is heated.
The principle of microwave heating is simply: when microwaves are radiated onto food, the food always contains a certain amount of water, and the water is composed of polar molecules (the positive and negative charge centers of the molecules are misaligned even in the absence of an external electric field), and the orientation of such polar molecules will vary with the microwave field. Due to this movement of polar molecules of the water in the food product. And the interaction between adjacent molecules, a friction-like phenomenon is generated, so that the temperature of water is increased, and thus, the temperature of food is increased. The interior of the food heated by microwave is also heated at the same time, so that the whole object is heated uniformly, and the temperature rising speed is high. He heats the food 5cm deep at a frequency of 24.5 hundred million times per second, speeding up molecular motion.
In order to overcome the defects, the invention builds the intelligent horizontal microwave oven and can effectively solve the corresponding technical problem.
