In the operation of household appliances may experience problems in its work. Some of them can be eliminated with their hands, while others require the intervention of the master. Today I will tell you what the principle of the microwave oven, how to prolong its life and how to choose the right model.
The apparatus of microwave oven
What microwave is made? If you understand where some item is and what is intended, you will be much easier to understand the operation of the microwave.
Basic elements of the microwave oven magnetron:
- camera - metal, with metallic door (which concentrates microwave (MW) radiation), which warms up the products are placed;
- transformer - a source of high-voltage power supply of the magnetron;
- The control and switching circuit;
- Microwave emitter - magnetron;
- waveguide - to transfer from the magnetron to the radiation chamber.
Extras:
- turntable or tray - is necessary for the uniform heating of the product from all sides;
- circuits and circuit - provide control (timer) and security (lock) device;
- fan - cools the magnetron and ventilated chamber.
How does heating food
Each piece of vegetable, meat, fish, fruit, millions of special molecules. In an electric field, they are arranged strictly in the direction of the field lines, "plus" to one side, "minus" to the other. If you change their polarity, then change direction.
Change polarity helps the microwaves. Under the action of microwave radiation with molecules tumble breakneck speed and literally contact each other at revolutions, thereby heating up.
This happens when we three palms against each other to keep warm. The frequency of the waves, which is used by almost all the microwave - 2450 MHz (1 MHz - is one million cycles per second). It turns out that the field, which contains the product molecules, changing the polarity of approximately 4.9 billion times per second!

How to choose a microwave oven: 4 rules
When choosing appliances, everyone is looking for the one that will last a long time without harm to health. So as not to stumble on defective goods during the selection of equipment, follow a couple of simple rules:
| Photo | recommendations |
 |
rule 1 The housing and the door should fit snugly together. If you see a gap between them - say model "Goodbye." Click on the metal when it is bent by pressing a finger - the material is not high-quality. |
 |
rule 2 Check out all the buttons and adjusting wheels in operation. |
 |
rule 3 Inspect the power cord and plug, try yourself to stick it into the socket and remove. |
 |
rule 4 Ask the consultant to show the work of each additional attachments if there is, find out how to remove the main parts. |
Most modern home appliances have their own websites. I advise you - before you go to the store, carefully read customer reviews. For purchase come with a list of selected models, and perform their own inspection.
Precautions: 4 ban
Did you hear about the dangers of rays from a microwave oven? I am of the opinion of a certain medium. Yes, the waves have a definite impact on the structure of the product and the human body.
On the other hand, the effects of an ordinary TV much stronger. I think that we should not be afraid to use the microwave oven for cooking, but it should be not too often.
Do not heat in the microwave frozen breast milk for the baby - the body of the newborn is still more sensitive to various influences.
How to operate the microwave and can not do:
| Picture | instruction |
 |
Tip 1 You can not reheat food in a metal bowl or send in an oven cutlery metal tools - this can damage the microwave device. |
 |
Tip 2 You can not send for heating the eggs and fluid in sealed containers! The fact that moisture evaporates creates a lot of pressure, which will lead to an explosion. |
 |
Tip 3 Capacity with pictures, silver and golden strips can not be used. Ceramics are likely to crack at the site of deposition (image). |
 |
Tip 4 Narrow necks in a glass - too bad. The fact is that the water begins to boil in the microwave is not as usual - no bubbles and easily overheated. The slightest awkward movement and water can splash out and burn your skin. |
Relative characteristic: 5 microwave ovens
You can share all of the microwave oven for 5 species. However, the structure they have roughly the same, the difference is in the details:
| Picture | Characteristics |
 |
Conventional oven or solo PriceFrom 2000 rubles Description: The most simple model has only two functions - heating and defrosting. Ideal for those who use the stove in rare cases. |
 |
Microwave with grill Price: from 3500 rubles Description: in addition to the basic functions of heating products and standard parts has 2 extra - built ten and a skewer, which are intended for the preparation of "grill" dishes. |
 |
Microwave oven with convection PriceFrom 4500 rubles Description: Microwave oven has the function of food is prepared blowing hot air, which is evenly distributed throughout the product surface. This gives the effect of cooking in the oven. Due to convection, better products and par fried baked through. |
 |
Multi-function microwave oven Price: from 6000 rubles Description: Most expensive models of microwave ovens have a wide range of possibilities - a grill and convection, and pressure cooker, etc... One oven can replace a number of other domestic appliances. |
 |
Mini microwave oven Price: from 500 rubles Description: Model, as well as solo, is designed exclusively for heating food, but is small in size. Some of these devices are wireless, which is very convenient for use outdoors. |
Summary
I hope I have adequately describe not only the principle of the microwave, but also help you in choosing the equipment. If you have any questions, or you know more - write in comments, I will be glad to read, and if possible to dot the «i».
