Wall-mounted energy-saving professional hair dryer working principle

The wall hair dryer is mainly used for drying and shaping hair, but it can also be used for local drying, heating and physical therapy in laboratories, physical therapy rooms and industrial production, and artwork. According to the type of motor it uses, it can be divided into AC series-excited, AC shaded-pole type and DC permanent magnet type. The advantage of series excitation type hair dryer is large starting torque, high speed, suitable for manufacturing high-power hair dryer; the disadvantage is that the noise, commutator has some interference with telecommunications equipment. The advantage of shaded-pole type blowers is low noise, long life, no interference with telecommunications equipment; the disadvantage is the low speed, poor starting performance, large weight. The advantages of the permanent magnet type blowers are light weight, high speed, simple manufacturing process, low cost, good value for money.

Although there are many types of blowers, but the structure is similar, are composed of shell, handle, motor, air blade, electric heating element, wind shield, switch, power cord, etc..

Working principle

Directly by the motor drive rotor driven by the wind blade rotation, when the wind blade rotation, air from the air inlet inhalation, the resulting formation of centrifugal airflow and then blown out by the front nozzle of the wind cylinder. Air through, if installed in the wind mouth of the heating bracket on the heating wire has been energized to become hot, then the blowing is hot air; if the selection switch does not make the heating wire energized to heat, then the blowing is cold air. Hair dryer is this to achieve the purpose of drying and shaping.

Hair dryer handle on the selection switch is generally divided into three gears, namely, off gear, cold air gear, hot air gear, and with the color white, blue, red sign. Some hair dryer handle is also equipped with a motor speed switch, choose the size of the air volume and hot air temperature is high or low when used. Various types of blowers behind or on the side of the shell, are equipped with a rotating round wind cover, rotate the cover to adjust the size of the cross-section of the air inlet, you can adjust the speed of the wind and the temperature of the hot air transported.

According to the use of the way to divide, there are handheld and pedestal hair dryer. Pedestal hair dryer can be placed on the table or hung on the wall to use, you can blow their own wind.

According to the way to send air, there are centrifugal blowers and axial flow blowers. Centrifugal type relies on the motor to drive the air blade rotation, so that the air into the blower to obtain inertial centrifugal force, and constantly exhaust air outward. Its disadvantage is that the discharge of the wind is not all flowing through the motor, the motor temperature is higher; the advantage is that the noise is lower.

Axial flow motor drives the rotation of the air blade, pushing the air into the blower for axial flow, and continuously exhausting the air outward. Its advantage is that all the discharged wind flows through the motor, the motor cooling conditions are good, insulation is not easy to age; its disadvantage is that the noise is greater.

According to the material used in the shell, there are metal blowers and plastic blowers. Metal blowers are strong and durable, and can withstand higher temperatures. Plastic hair dryer light weight, insulation performance is good, but easy to age, and poor heat resistance.
