Harm of induction cooker and matters needing attention
Induction cooker is now a very popular cabinet, which can generate heat directly at the bottom of the pot, without naked flame or conduction heating, so the thermal efficiency is greatly improved. It is an efficient and energy-saving product.
It breaks the heating principle of traditional open fire cooking method using magnetic field to induce current (also called eddy current). The induction cooker generates an alternating magnetic field through an electronic circuit board. When the iron-containing pot bottom is placed on the kitchen surface, the pot bottom cuts the alternating magnetic field lines, and an alternating current (i.e. eddy current) is generated in the metal part of the pot bottom. The eddy current makes the free electrons in the iron material at the bottom of the pot move alternately in a vortex way, and the pot is made of Joule heat of current (p = I 2 * r).
Harm of induction cooker
1. Electromagnetic radiation produced by induction cooker acts on human body. Electromagnetic induction can redistribute the charges of nonpolar molecules to produce polarity, and at the same time redistribute polar molecules, thus interfering with the activity of enzymes expressed by receptors on human biofilm and causing abnormal cell function. The most obvious symptom is causing computer radiation spots.
2, electromagnetic radiation has an impact on the human body, interfere with people's normal physiological activities, a long time will lead to neurasthenia. Such as headache, dizziness, insomnia, dreaminess, forgetfulness, etc. In severe cases, it can lead to palpitation and arrhythmia.
3. Electromagnetic radiation can lead to endocrine disorder, which directly leads to the decrease of injury resistance. Lead to stunting of children; Acting on thyroid gland and parathyroid gland will make thyroxine and parathyroid gland abnormal, leading to developmental disorders in children.
4. Electromagnetic radiation can change the structure of cells and produce mutant cells. When human immunity is low, the incidence of cancer will increase. Biofilm dysfunction caused by electromagnetic radiation is indeed destructive, which will inhibit cell activity, such as sperm production and activity decline, infertility, facial skin cell metabolism disorder and pigmentation.
Many pregnant women are very concerned about the harm of induction cookers, which is necessary. According to the survey of the World Health Organization from 65438 to 0998, the main hazards of induction cookers can be roughly divided into the following five types:
(1) electromagnetic radiation is one of the main causes of cardiovascular disease, diabetes and cancer mutation.
(2) Electromagnetic radiation will directly harm human reproductive system, nervous system and immune system;
(3) Electromagnetic radiation is one of the inducing factors of abortion, infertility and teratogenesis in pregnant women.
(4) Excessive electromagnetic radiation directly affects the development of children's body tissues and bones, resulting in decreased vision and liver hematopoietic function, and in severe cases, retinal detachment;
(5) Electromagnetic radiation can make male sexual function decline and female endocrine disorder.
Matters needing attention in the use of induction cooker
1, should use a good quality socket? Poor socket contact will cause the burner or induction cooker to fail to work normally.
2. When the plug wire is damaged or the power plug is not firmly inserted into the socket? Never use an induction cooker.
Don't bend, bind or exert excessive force on the wires? This will cause damage.
4. Do not place any obstacles on the plug or power socket of this machine.
Never plug the plug into the socket where several other appliances have been plugged in? The current shall not exceed the limit of the socket, and the working current of this device is about 10 amp.
6. Don't use the induction cooker in damp or near the flame.
7. Before using the induction cooker, please turn it on for 10 minutes? After the electronic components in the induction cooker are stable, start the machine for functional operation.
So how to prevent electromagnetic radiation of induction cooker? The so-called radiation protection clothes we wear in our daily life have no effect at all (not only induction cookers, but also ordinary computers). So the best way is to stay away from the induction cooker, at least half a meter away.
How many years can the induction cooker last?
Service life of induction cooker
Under normal circumstances, induction cookers can be used for five to six years. If you pay attention to maintenance, it will last longer. Daily maintenance can be done by some simple methods, such as not letting the power cord get wet, not letting water enter the inside of the panel when cleaning, and cleaning the shell in time if there is dirt, but do not use strong acid and alkali solution, dry it after washing, and naturally ventilate the room.
Causes of premature damage of induction cooker
The reason for the premature damage of induction cooker is nothing more than frequent failures, which can no longer be used. For example, in the process of use, the common faults are: the stove does not heat up when it is hot, the indicator light is on but the buzzer does not ring, the heat preservation function does not work or even fails, the power is not adjustable, and the high tone is loud. If something goes wrong, stop using it at the first time and find out the reasons side by side.
Which brand of induction cooker is good (for reference only):
1, beautiful
Midea is a world-famous electrical product with its own patent production rights. Midea's induction cooker adopts an integrated flat plate, and the furnace plate is seamlessly connected with the panel, which is simple and beautiful, easy to clean, and the cooking firepower can be adjusted in place instantly, which is multifunctional and convenient.
2. Supor
Supor has been committed to producing high-quality kitchen appliances, and everyone must be very familiar with it.
