Compared with microwave ovens, electric ovens are not considered essential household appliances in the kitchen. It may be related to eating habits. The popularity of electric ovens in China has not been high, and everyone’s understanding of ovens is also unclear. There are misunderstandings, and many people are confused. They wonder whether electric ovens will produce radiation when cooking food? It is said that induction cookers and microwave ovens have strong radiation, and it is best not to get close to them when using them. So do electric ovens that look similar to them have radiation? The editor will introduce it to you below!
Type:
Household electric oven
At present, there are two main types of household electric ovens on the market: veneer panel electric ovens and solid wood electric ovens
Veneer panel electric ovens
Veiner panel electric ovens The oven is a heater used in the south in winter. It is also called a stove, an electric fire barrel, a foot warmer, etc.! It can be widely used in various civilian and public applications such as residences, offices, hotels, hospitals, schools, and simple mobile houses. *Building is a new type of energy-saving heater. Compared with traditional electric heaters and air conditioners, it saves 80 to 90% of the electricity consumption. Most of its production areas are in Hunan, Anhui, Jiangxi and other regions. It mainly uses far-infrared Providing warmth by radiation and heat diffusion.
Solid wood electric oven
The function of solid wood electric oven is almost the same as that of veneer, and the only difference is that its external structure is different, and it is all made of authentic fir Or made of logs, it is strong and durable, waterproof, anti-corrosion, anti-vibration, moisture-resistant, and has a woody fragrance! The veneer is not waterproof or moisture-proof!
Usage:
1. Home heating: When family, relatives and friends are reunited for entertainment, they can sit around a larger electric firebox to keep warm, which is comfortable and warm, and is conducive to communication with relatives and fun;
2. Reunion of friends Entertainment or chess and card rooms are used for playing cards and mahjong;
3. Personal work, study and entertainment: individuals can use small devices for online entertainment, study, and work at home, offices, dormitories, shops, etc. A little warm and comfortable.
Does an electric oven radiate?
If we can answer the question about electric oven radiation simply and directly, it is: there must be, and there is a lot of radiation! But this does not affect our normal health. of use. Why do we say this? To explain this problem, first we need to understand the broad concept of the word radiation. In life, we are often exposed to two types of radiation, one is electromagnetic radiation and the other is thermal radiation. Usually we refer to electromagnetic radiation as something that can damage people's health and cause endocrine disorders. Radar systems, television, mobile phone and radio transmission systems, radio frequency induction and medium heating equipment, radio frequency and microwave medical equipment, various electrical processing equipment, communication transmission stations, satellite earth communication stations, large power generation stations, power transmission and transformation equipment, High-voltage and ultra-high-voltage transmission lines, subway trains and electric trains, and most household appliances can produce electromagnetic radiation sources of various forms, frequencies, and intensities. We often hear some advice in life, such as not plugging in the charger to use the mobile phone, not getting too close to the TV, etc. These are effective measures to prevent excessive electromagnetic radiation from harming the body.
Another common type is thermal radiation. Thermal radiation simply conducts heat energy and is basically harmless to humans. The method we have used to heat food for thousands of years has basically used thermal radiation. For electric ovens, they also use thermal radiation to heat food. This is not essentially different from the thermal radiation we use to heat charcoal or gas stoves, but the source of the energy conversion form is different. An electric oven converts electrical energy into heat energy. Its working principle is actually very simple. People who have seen the circuit diagram of an electric oven may be surprised, because the circuit diagram of an electric oven is too simple. In fact, it is through a few resistive heat pipes, and when the current passes through A large amount of heat radiation heats food.
Of course, it cannot be said that the electric oven is completely free of electromagnetic radiation, because as long as there is current flowing through it, it will emit electromagnetic radiation, and any household appliance will have it.
However, the amount of electromagnetic radiation from an electric oven is very small, and the harm to the human body is basically negligible. Its working principle is just like the resistance wire of an incandescent lamp or an electric heater. When the current meets the resistance, it emits heat and does not produce high-frequency electromagnetic oscillation. The electromagnetic radiation is limited to weak electromagnetic waves generated when the current passes through it. This is similar to the active emission of mobile phones and TVs. The magnitude and intensity of electromagnetic waves are completely incomparable. Basically, it will not cause any harm to the bodies of healthy people (it does not exclude the impact on pregnant women and special groups).
So since the amount of electromagnetic radiation from an electric oven is very small, why are people so worried about its radiation? In fact, this has something to do with microwave ovens, because the popularity of electric ovens in China is very low, and many people will Toaster oven mistaken for microwave. Microwave ovens have different heating methods. Microwave ovens are cooking utensils that use food to absorb microwave energy in the microwave field to heat itself. The microwave generated by the microwave generator in the microwave oven establishes a microwave electric field in the microwave oven cavity, and certain measures are taken to make this microwave electric field evenly distributed in the oven cavity. Food is placed into the microwave electric field, and the cooking time is controlled by the control center. and microwave electric field strength for heating. Microwave is actually a kind of high-frequency electromagnetic wave. If it leaks and affects people, it will cause harm to people. In fact, there are many injury accidents due to improper use or quality problems of microwave ovens. Therefore, everyone is deeply impressed by the radiation of microwave ovens. In addition, the designs of electric ovens and microwave ovens are often very similar, so many people confuse the two products. Therefore, it is not surprising that they are worried about the radiation problem of electric ovens.
Although electric ovens have no radiation hazards, you still need to pay attention
The first thing to pay attention to is the high temperature. Electric ovens generate high heat that other household kitchen appliances do not have. If you are not careful, it will Burns may occur easily. Even if there is no direct skin contact, high temperature will be harmful. Generally, the power of electric ovens is very large (usually several thousand watts). Generally speaking, the front cover of electric ovens is made of heat-insulating materials, but currently most of them are several hundred watts. Yuan's household ovens all use single-layer glass panels. The heat insulation of the front panel is not particularly good. A large amount of heat will still be emitted during use. Especially after many people just bought an electric oven, they like to stare at the food. The changing process during baking, but everyone knows that if people look at the electric oven for a long time, their eyes will be damaged, and in severe cases, it will lead to the emergence of cataracts.
In addition, it should be noted that fried dough sticks and fried cakes cannot be heated in an electric oven. This is mainly because the remaining oil in the fried dough sticks will splash when exposed to high temperatures, resulting in the appearance of open flames. This will not only cause damage to the electric oven, but also endanger the safety of the user. In addition, some protection should be provided to the heat pipe of the electric oven according to the different ingredients being cooked. Usually the heat pipe of the electric oven is exposed to the outside. When heating some meat, the internal grease can easily drip on the heat pipe, which will also produce an open flame, which not only affects The heating efficiency of the heat pipe also has safety hazards. Therefore, when using the oven to cook food, you must first consider safety issues. For some foods that are prone to dripping oil, it is best to put a baking sheet on the bottom and cover it with tin foil to eliminate the above hidden dangers. In addition, the oven must be used in accordance with the usage specifications, especially when taking cooked food. Since the oven has to reach a temperature of about 150-200°C during the baking process, the outer surface of the oven will also reach a high temperature of hundreds of degrees. You can easily get burned if you are not careful. Relatively speaking, using an electric oven requires more caution than other kitchen appliances.
How to choose an electric oven
1. Oven size
There are certain considerations in choosing the size of the oven. Generally speaking, 18 liters is a standard. Ovens smaller than 18 liters are all small ovens. Small ovens are only suitable for baking chicken wings, biscuits and the like. If you bake cakes, they are a bit inadequate. The principle of choosing an oven is usually based on the amount of food to be baked. For example, a 30-liter oven can meet the needs of a family of 3-4 people. However, for users who have high requirements for baking quality, they usually choose a larger oven.
So based on the above reasons, when choosing the size of the oven, you must not only consider the number of family members and baking quality, but also consider the space in the kitchen for a large oven, as well as the time and cost of baking food, etc.
2. Number of heating tubes
The most important electronic component of the oven is the heating tube, because the quality and quantity of the heating tube directly determine the heating efficiency of the oven. Electric ovens above 25 liters are generally equipped with 4 heating pipes. The distribution of the 4 heat pipes is basically two at the top and two at the bottom. Because the heating pipe not only has the purpose of heating, but also plays an important role in maintaining a constant temperature in the oven. Therefore, the more heat pipes, the better the temperature balance inside the oven. In principle, the more heat pipes, the better. Of course, the number of heat pipes generally customized by manufacturers is determined based on the size of the oven. Generally, ovens between 18 and 40 liters usually have 4 heat pipes, and ovens above 40 liters will be equipped with 6 or even 8 heat pipes. When purchasing, if there is not much difference between ovens of the same capacity, it is recommended to choose one with more heating tubes.
3. Which one is better, the mechanical version or the electronic version?
Although the working principle of electric ovens does not have much technical content, there are still two types of temperature control. One is mechanical control. The other is electronic temperature control. The general principle of a mechanical thermostat is a switch controlled by the thermal deformation of a bimetallic piece. Because the thermal expansion and contraction coefficients of the two metals are different, the temperature can be controlled. The electronic principle is that the electronic temperature probe detects the temperature and controls the opening and closing of the current in the microcircuit relay to achieve constant temperature. People who are new to electric ovens may think that electronic temperature control is more advanced.
I have said a lot before, which can basically dispel people’s doubts about electric oven radiation. Of course, it does not mean that the food cooked in the electric oven is perfect. If you are not careful when using it, there will also be hidden dangers that endanger your health. Therefore, you can use the electric oven with confidence without worrying about its radiation problem, but you should still use it carefully to avoid burns. Regarding the question of whether electric ovens have radiation, I will answer it here first. If you want to know more, please continue to follow Tubatu to learn decoration!
