Hair dryer is an electrical appliance that we have a hair shaping in our daily life. It is mainly suitable for some physical therapy, beauty and hairdressing. It is commonly used in our daily life. It is called hair dryer in our daily life. There are many types of electric hair dryer. In our daily life, hair dryer is very harmful to human body, and its radiation is not prominent But when it is used, the damage to hair and hair is still relatively large.
According to the classification of his grace, therefore, in daily life, the effect of hair dryer is different. Power is mainly in daily life, but also more, ah, the average household use is 600 watts to 1800 watts, barber shops generally use more. So pay attention to it in daily life.
1. According to the type of motor used, it can be divided into AC series excitation type, AC shaded pole type and DC permanent magnet type. The advantages of the series excitation hair dryer are large starting torque and high speed, which is suitable for manufacturing high-power hair dryer; the disadvantages are large noise and commutator has certain interference on telecommunication equipment. The advantages of the hood type electric blower are low noise, long service life and no interference to telecommunication equipment; the disadvantages are low speed, poor starting performance and heavy weight. The advantages of permanent magnet hair dryer are light weight, high speed, simple manufacturing process, low cost, good quality and low price.
2. According to the way of use, there are hand-held and pedestal hair dryers. The support type hair dryer can be used on the table or hung on the wall, and can be used to blow yourself.
3. According to the way of air supply, there are centrifugal hair dryer and axial flow hair dryer. The centrifugal fan is driven by the motor to rotate, so that the air entering the electric blower obtains the inertial centrifugal force and continuously exhausts the air. Its disadvantage is that the exhaust air does not flow through the motor completely, so the temperature of the motor is higher; the advantage is that the noise is low. The axial-flow motor drives the wind blade to rotate, and pushes the air entering the hair dryer to make axial flow and continuously exhaust air. Its advantages are that all the exhaust air flows through the motor, the cooling condition of the motor is good, and the insulation is not easy to aging; its disadvantage is that the noise is large.
4. According to the materials used in the shell, there are metal type hair dryer and plastic type hair dryer. The metal type hair dryer is durable and can withstand high temperature. Plastic hair dryer is light weight, good insulation, but easy to aging, and poor high temperature resistance.
The above is the power of hair dryer, which is more in daily life. Generally, the power of hair dryer is 600 to 1800 watts. According to the type of electric, it is very harmful to human body in daily life. Its radiation is not prominent, but the damage to hair and hair is relatively large when it is used. In daily life or choose less use of hair dryer, natural air drying is better.
