A Glimpse on Vacuum Cleaners: Wonderful House Helpers

Vacuum cleaners were invented by Daniel Hess in 1860. These have become a household name since then. The amount of effort exerted in cleaning floors in a house is decreased by the vacuum cleaner.

How does the vacuum cleaner work? It operates on the basic principle of “suction”. Suction fundamentally works on the theory of pressure. Everyday we drink beverages through sipping. When using a straw, the pressures on the mouth end of the straw decreases as the pressure in the end of the straw increases causing the liquid to flow. This simply explains how suction mechanism works.

This same theory, “suction mechanism”, applies to vacuum cleaners. It is what makes the cleaner work its wonders. The suction mechanism in a cleaner however, is a little more complicated. We will discuss in this article the structure of the vacuum cleaner and the different kinds of vacuum cleaners founded on precise standards of Physics.

When we take a look on the vacuum cleaner we wonder what is inside it. The integral structure of the vacuum cleaner is made up of six essential components:

1. Inlet – the point from where the vacuum cleaner sucks up the debris and dust from your home or office. Usually this part has a host of accessories shaped in various ways to help you clean.

2. Exhaust – an outlet built into vacuum cleaner either to spurt out the air coming in through the inlet due to suction, or to suck air when you use the vacuum cleaner in the “blow” mode.

3. Electric Motor – it primarily produces suction.

4. Fan – starts and maintain the suction mechanism running.

5. Bag – it collects and filters the sucked air of dust and debris that are collected by the inlet.

6. Housing (also called Cabinet) – serves as one compartment for all the components. The components arranged in an efficient method.

Vacuum cleaners all have the same built in feature – the “blow mechanism”. The blow mechanism is triggered by the rotation of the fan in the other way. All users of this household appliance are cognizant to the fact that vacuum cleaners runs on electricity. As soon as it is plugged and turned on, the electric motor works and rotates the fan. Once the fan rotates, the gaunt blades push the air towards the exhaust outlet. The air pressure which gradually reduces as it passes behind the fan generates the suction that pulls the dirt or dust. The collected trash goes through the exhaust towards the bag.

Electric vacuum cleaners came out in the early 1900’s. Only rich families could afford electric vacuum cleaners during that time. Prevalent versions of electric vacuum cleaners then were central vacuum cleaners which included a big fan at the exterior of houses they were integrated to. Vents were located at different places in the house or building which was connected via bendable pipes to the large fan. Debris was collected via large canisters outside the house which were emptied several times during the year.

There are also wet and dry versions of vacuum cleaners which are used to clean solids and liquids. Buckets were usually used for wet vacuum cleaners.

A new technology used in vacuum cleaners where air sucked by the machine is channeled through spiral tubes which makes use of the centrifugal force generated by the circular or spiral motion of the air to separate the debris from the air. This though, is not the end of the development of the vacuum cleaner as more and more technologies are being developed in record times today.
