What's inside the microwave
A microwave oven is a useful household appliance. It has long become a familiar attribute of every kitchen. It is used to heat food and prepare new dishes.
Let's look at the internal structure of the microwave. This will help you understand the principles of its operation.
The content of the article
Main part of the microwave
The main element in any microwave is the magnetron. It is an unusual light bulb. It contains a vacuum chamber. The area of responsibility of the part is microwave radiation. The magnetron does its job of converting incoming voltage into microwaves. In addition, he brings them into the oven chamber. Thanks to them, food is heated.
Parts that ensure the operation of the device
The main components that ensure the operation of the device are a fuse, a rectifier and a transformer.
Circuit breakers
The fuse is a small but very important detail. It looks like a small metal thread in a glass flask. It is closed on both sides with special caps.
The microwave is equipped with three fuses.
- Network protects the electrical circuit from unexpected voltage surges.
- High voltage protects the transformer from possible overloads. Refers to magnetron protection elements.
- Third type installed in furnaces equipped with an electronic control panel. He deals with converting incoming current into voltage. If it breaks, it is quite difficult to replace it.
The type of fuse used in a particular model can be found in the instruction manual.
Rectifier
A rectifier is needed to power the magnetron. It converts the incoming voltage into DC. Consists of a rectifying diode and a decoupling capacitor.
Transformer
The transformer energizes the magnetron. To start the work, a high voltage supply is required, because the standard one for the magnetron is not enough. A high-voltage transformer converts the incoming current, reaching the required values. Thanks to this, the magnetron is included in the overall process.
Parts that control microwave functions
A microwave oven is a rather complex mechanism. The operating procedure is based on the relationship between all parts. Consequently, the failure of one component leads to equipment malfunction. Therefore, the elements responsible for microwave functions are of great importance.
The main control part in microwave ovens is the power supply.. It is responsible for maintaining the given power. In addition, it turns off the oven after a set period. It can also be used to adjust the power level during cooking. The block is different from other parts of the stove. It has its own power source.
Additional details
There are always other parts in a microwave.
Fan
It is impossible to use the stove without a fan. He specializes in blowing electronic circuit components. Thus, it controls their heating and optimal temperature. Sucking air from the room, it directs it to the magnetron. After which it correctly distributes it over the entire surface.
During heating and cooking, the fan creates increased pressure.This measure is necessary to remove warm air and steam through ventilation. They arise during microwave activity. Located on the back wall of the device. Works in all microwave modes.
Glass table
The rotating table is responsible for uniform heating of the dish. It is made of heat-resistant glass.
Lamps
Used to illuminate the oven chamber. The power circuit includes a start relay. Thanks to this, the interior lighting is activated when food is heated or the door is opened. Therefore, using a microwave with this function is much more convenient. Similar elements are also installed in refrigerators or sewing machines.
The lamp is located in a special box, which is located next to the transformer. In case of malfunction, you can install a new one yourself, at home.
Important! The process of replacing a light bulb should be carried out according to safety regulations. The device must be disconnected from the network at this time.
Protection system
A microwave oven has inside a device with powerful radio emissions - a magnetron. If care is not taken, it can cause serious harm to human health. For additional protection and safe use, the camera of the device is placed in a metal case. Thus, it is impossible for radiation to escape outside.
The door fits tightly to the chamber and has a special gap. Due to this, the radiation wave propagates inside the microwave.
The glass in the door has a special coating in the form of a metal mesh. It controls the area of radiation propagation and prevents it from leaving the device.
The microswitch system ensures that the microwave cannot be used with the door open.
The microwave oven has become an indispensable assistant for modern people. This is a necessary addition to the stove and oven. A smart mechanism will be useful in performing many tasks and making everyday work in the kitchen easier.
