The electric blanket can provide a constant source of heat, which can make people warm quickly when the winter is cold. It is a rare warm product. Some people are very curious about the heating of electric blankets. They also want to know the principle of heating blankets. When using electric blankets, it is easy to have safety accidents. Let's take a look at the precautions for using electric blankets. First, what is the principle of electric blanket heating? Generally, the electric blanket is composed of heating elements, base core, fabric, power cord, junction box and control switch. When the electric blanket is powered on, the 220V AC voltage is limited by C1.R1, D1. D2 rectification, C2 filtering, after DW voltage regulation, obtain a voltage of about 9V for IC. When the power is turned on at room temperature, the temperature is gradually increased because the V2 heating wire is energized and heated. As the temperature of the thermal sensor BG1 increases, the penetration current Iceo increases and V2. V6 rises. When V2>Vz, V6≥Vf, the IC flips and the 3 feet become low. The BCR cuts off the hot wire of the post office and stops heating. The temperature begins to decrease gradually, and the Iceo of BG1 gradually decreases, and V2.V6 decreases. Second, electric blanket use precautions 1. The electric blanket is essentially an electric appliance, so it has its own unique method of use. Therefore, before using it, it is best to carefully read the instruction manual of the electric blanket and then strictly follow the instructions to avoid the risk of accident. It will be very low, and many people have an electric blanket accident caused by operational errors. At the same time, when using the electric heating press, it is strictly forbidden to fold the electric blanket, so it is easy to make the electric blanket have pile and pleating phenomenon, the heating is not good, and when using the electric blanket, it can not be compared with other The power supply is used in common, otherwise the electric blanket is likely to transmit a short circuit. 2, many people use electric blankets like to power all night, this is actually a very bad habit. In particular, the preheating type electric blanket is actually prohibited from being used overnight during the use process. Instead, after the heating blanket is heated, the person needs to turn off the power before going to bed. This must be noted. In addition, children do not understand electric blankets, so be sure to have someone to accompany them when using them. Electric blankets are different from ordinary bedding. They are also electrical appliances. Therefore, do not place any hard materials on them when using them. Otherwise, the internal components of the electric blanket may be damaged, making the electric blanket useless. What is the principle of electric blanket heating? The reason for the heating of the electric blanket is clear. If you don't understand it after reading it, you don't need to be too nervous. Just know how to use electric blanket. There are many precautions for the use of electric blankets. I hope that everyone can pay more attention when using electric blankets, and avoid the trouble caused by improper use of electric blankets. |
