The image shows a small electrical device, viewed from one side, with the end where the air exits on the left side and the handle at the bottom.

The hair dryer is represented by a tubular shape, from side having a rectangular shape at the top, with rounded ends, and a handle in the form of a vertical rectangle, slightly curved. It is rendered by the texture of horizontal and parallel lines.

On the handle, at the bottom, left edge, there are two buttons for adjusting the wind speed and for hot or cold air. The buttons are rendered by two embossed semicircles. Usually there is a three-way switch button that regulates the motor speed: high, normal, off.

The hair dryer is used for drying wet hair by blowing hot or cold air that is drawn in by the propulsion of a small fan inside driven by a motor. The air at room temperature is sucked through the vents in the back casing, the right edge, rendered by an embossed semicircle. Then heated or not, depending on the selection, the air is propelled at high speed to the other end, through a round front grill. The front grill is heat resistant and acts like a protective barrier. (1) By bringing the hair dryer close to wet hair, at a certain distance so as not to burn it, evaporates to the last drop of water left on the hair.

In order for the motor to work, it must be powered by electricity. Therefore, a plug cable or cord is attached to the lower end of the handle and plugged into the socket. The cable is fixed at the base of the hair dryer by with a cable restrain. The cable restrain protects the cord from excessive bending when in use. The cord is is marked as a thickened and wavy line.

Because it is an electrical device, which is usually used in the bathroom, close to wet surfaces, it should not be left in contact with or near water, as there is a high risk of electric shock.
