If you simply and directly answer the question about the radiation of electric ovens, that is: there must be, and there is still a lot of radiation! But this does not affect our normal use. Why do you say that? To explain this problem, we first need to understand the broad concept of radiation. In our life, we often come into contact with two kinds of radiation, one is electromagnetic radiation and the other is thermal radiation. Generally speaking, electromagnetic radiation will damage people's health and cause endocrine disorders.

The electric oven converts electric energy into heat energy, and its working principle is very simple. People who have seen the circuit diagram of the electric oven may be surprised. Because the circuit diagram of the electric oven is so simple, it originally passes through several resistance heat pipes, and when the current passes, it generates a lot of thermal radiation and heats food.

Of course, it can't be said that the electric oven has no electromagnetic radiation at all, because as long as there is current passing through it, it will produce electromagnetic radiation, which is true of any household appliance. However, the electromagnetic radiation of electric oven is very small, and the harm to human body can be ignored. Its working principle is the same as that of incandescent lamp resistance wire and electric heater. When current meets resistance, it will emit light and heat, so it will not cause high-frequency electromagnetic vibration, and electromagnetic radiation will only produce weak electromagnetic waves when current passes through, which can't be compared with the size and intensity of electromagnetic waves automatically emitted by mobile phones and televisions, and will not cause harm to our bodies at all.

Then the electromagnetic radiation of the electric oven is very small. Why are we so worried about its radiation? It turns out that this has something to do with the microwave oven. Because the popularity of electric ovens in China is not high, many people will mistake them for microwave ovens. The heating mode of microwave oven is different from that of electric heating box. Microwave oven is a cooking appliance that uses food to absorb microwave energy in microwave field and heat itself. The microwave generated by the microwave generator of the microwave oven establishes a microwave electric field in the cavity of the microwave oven, and adopts certain methods to make this microwave electric field distribute as evenly as possible in the cavity of the microwave oven. Food is put into this microwave electric field, and the cooking time and microwave electric field intensity are controlled by the control center for heating.
