Vacuum cleaner helps you to keep your house dust free and clean. Do you know how vacuum cleaners work? Learn about the working of your machine which will help you improve the performance of your vacuum cleaners and give you the knowledge to use them safely.
Working Principle
Vacuum Cleaners work on the principle of suction. It uses the scientific law of “air always flows from high pressure area to low pressure area”. The electric motor inside the vacuum cleaner creates a sort of vacuum or low pressure area, because of which the outside air rushes into the vacuum cleaner through it’s let along with the dust and debris.
Components of a Vacuum Cleaner
A vacuum cleaner is made up of seven main components.
1. The main body of vacuum cleaner
2. Inlet where you connect different type of nozzles
3. Outlet through which air sucked in escapes
4. Pours bag which collects the dust
5. Electric fan which creates the vacuum
6. Electric motor which drives the fan
7. A control switch and electric cable to connect to the power source.
The actual Working
When you switch on your vacuum cleaner, the electric motor starts driving the vacuum fan which rotates at high speed. The blade of the vacuum cleaner fan is made at a particular angle which helps it pull the air from inlet side and push it out through the outlet. Note that, when you use the “blow option” on a vacuum cleaner the fan starts rotating in the opposite direction causing the air to flow in the opposite direction. That is air is pulled through the normal outlet and blown outside through inlet. During suction the outside air along with dust and contamination enters through the inlet and passes through a porous bag which allows only the air to pass through and collects the dust inside it. Later you can conveniently remove all the dust and debris from this bag.
