A tumble dryer or cloth dryer is a household device that is very useful for eliminating moisture from clothes. Generally, it is used after washing the clothes, and some driers are also integrated with washing machines.
Most of the dryers have a revolving drum known as tumbler in which, warmed air is dispersed to evaporate the water molecules from the cloths. The tumbler is revolved to maintain some gap among the articles in the cloths.
However, delicate clothes may shrink and fade with extensive usage of drier. Because of these possible adverse affects, most of the people follow open air techniques such as clotheshorse and clothes line.

Air Circulation
Wondering how does the air really enter the dryer? Well, it is fairly simple – the air enters the dryer via few holes on the machine. Air passes inside the body of dryer via a wide hole from the front side of the dryer. Because of the heated air, water molecules on the clothes will get evaporated and make the cloths dry. The entire process is explained with the help of figures.
After air passes into dryer, first it encounters a heating element, and then it passes into the dryer’s body.

It is sucked by the heating element, gets heated up, and later it enters the clothing tumbler.
This is a traditional nichrome-wire heating element, which is quite similar to the heating element. The heating element in most of the dryers requires power, which ranges from 4,000 to 6,000 watts.
The air passes by the means of heating element and holes, which are situated on the back side of the tumbler.
This heated air is responsible for drying the clothes.
