Working of Vacuum Cleaner explained
We come across a vacuum cleaner almost every day. From room cleaning to carpet cleaning, we use it extensively. But the question remains how do vacuum cleaners actually work? So here is the answer.
First of all, the vacuum cleaner is a simple and effective way to handle cleaning. We can simply remove dust, debris lying around the home. It also comes handy in places difficult to reach by hand. In addition, the last character is its efficiency. It can do house cleaning much much faster.
The vacuum cleaner sucks the air from the inlet by creating negative pressure inside. Then, it filters out the outgoing air by HEPA filter. It collects dust separately in a dust bag.
How does a vacuum cleaner work?
The vacuum cleaners work on the principle of negative pressure creation. We actually find it everywhere. The vacuum cleaner consists of a fan with a motor. As the fan rotates it sucks the air inside from the inlet. Air carries all the dust particles and debris with it.
Furthermore, the fan keeps on rotating faster and push the air inside the dust bag. The vacuum cleaner has space limitations. So, the air inside must go out from somewhere. Here comes the exhaust port of the vacuum cleaner. The exhaust port is nothing but an air outlet. The air coming inside goes out from the outlet and the fan keeps on rotating. So, the fan keeps on pulling the air and forcing it out from the outlet.
In addition, the outgoing air should not carry small particles as it may be harmful to health. The air getting out must be clean and breathable. The vacuum cleaner must separate out dust particles. So, in order to solve this problem, the vacuum cleaner has a HEPA filter.
The vacuum at the inlet carries a lot of dust, small particles, grim and also carries particles invisible to eyes. The small particles and grim are filterable by the dust-bag itself. However, small particles pass through the dust-bag. These small particles then pass through HEPA (High-Efficiency Particulate Arresting) filter. This filter arrests small particles and only allow clean air to pass through.
The vacuum cleaner comes with a lot of attachments. Actually the power of the motor doesn’t highlight vacuum cleaner’s exact power. The attachment actually determines its real power. The attachment is nothing but the intake port pipe. The smaller the intake port more the suction power it generates. As the same amount of air passes through the narrow intake port. Hence, air must move faster as the intake becomes smaller and smaller. So, these attachments have different powers according to their intake size.
Configurations of vacuum cleaner
Vacuum cleaners come in different sizes and shapes. They also have different configurations according to their use. The upright vacuum cleaners have a rotating brush roll. This brush roll creates sweeping action to remove dirt. The canister type is more popular due to its flexibility. It has a typical dust bag in a canister that holds the dust. We can connect different heads for various purposes to this type of cleaner.
Furthermore, the drum type vacuum cleaners are generally industrial. They have large drums to accommodate a large amount of dust. So, the user can cover large areas such as an industrial complex. The wet dry vacuum cleaners can clean liquid spills. Thus, you can accommodate wet and dry debris.
Backpack vacuum cleaners are also available. These are most common in industrial areas. The handheld ones are having small batteries that power the motor. These can be useful for cleaning electronic equipment such as a laptop.
The robotic vacuum cleaners are relatively new. They are typically smaller in shape and portable. They work on their own and can determine obstacles. Furthermore, the cyclonic cleaner is also a type of vacuum cleaner. It works on the mechanism of centrifugal force. It doesn’t have a dust bag. Instead, the dust particles are thrown out of the vessel by centrifugal force. These particles then fall into a separate drum. It is almost similar to the working of the dryer in the washing machine.
Furthermore, the central vacuum cleaner is another type of cleaner. It has a central unit that acts as a suction unit. The suction inlets are located in every room while the user just needs to carry a hose. The vacuum truck is another type of cleaner. These trucks are nothing but large vacuum cleaners that roam around the city to clean public places.
In conclusion, irrespective of the configuration vacuum cleaners create negative pressure, suck in air, filter out dust and release air. All of them work on the same working principle.
