How does a hair dryer look?

The funny thing is if we look at a hair dryer, it sounds like a gun but it doesn’t have a trigger, and the hair dryer has a screen at the end of the tube which is covered by a grill so bugs or other objects can’t get inside. There is an off & on switch. There is another button or switch in some hair dryers that control the airflow. You will find some hair dryer with a regulator that helps to monitor the temperature of airflow. Inside of a hair dryer, there is a fan that is like water wheel.

How does it work?

Now the question is how does a hair dryer work? It’s one kind of an electric device, which blows regular or warm air over wet hair and the hair gets dried. A small size of motor sites in the interior the fan and it is confidently attached to the top of the engine. When the power is supplied to the motor, the motor and fan start to spin. The movement of the fan’s blades draws air through the small round air inlets inside cover of hair dryer. Those small holes are roofed by safety screen which keeps other things to get sucked inside. Now the natural air is heated. For hot air, a coiled wire is used that is wrapped around insulating board for heating the air. The coil is made with nichrome wire. Nichrome wire is an alloy of two metals those are nickel and chromium. Nichrome is used because it has two advantages: it’s a poor conductor of electricity like copper wire and when it is heated it never oxidize. Airflow of the fan is forced through the heating part by the form of hair dryer cover. Then the hot air is blown down the tube of the hair dryer. When you press the high or low, the motor generates heat according to that. The varying airflow depends on the modulation speed at which the motor spins. It is performed by alerting the current supply through which the circuit supports the motor. The motor and fan will turn slowly if the power source is small. With more power the motor will speed up and fan will turn fast, more air will be drawn in which will increase the airflow. The technological advancement has made the hairdryers develop more useful feature than your older ones. The latest hair dryers are lightweight, and travel-friendly comes with multi attachments for many different styles, less damaging to your hair and safer too. Some hair dryers will auto shut off if it has become too hot.
