What is an energy-saving fan?
Energy-saving fans, classified according to the international patent classification table, belong to department of mechanical engineering, heating department and air conditioning department. Gas regulation; Ventilation; Air flow is the application category of small screen and ventilation;
What are air supply and exhaust ducts? Open a group technical field. Its purpose is to solve the problems of large power consumption and long-term use of fans. This is harmful to the health of users. It mainly consists of an energy storage knob, a box, a sunflower fan and a transmission. Shaft, fan neck and transmission gear.
It is characterized in that the middle position of the transmission shaft is stereoscopically installed on the fan. The middle cavity position of the neck and the lower end position of the fan neck are bonded and connected at the opening position of the right middle end of the box. The lower position of the transmission gear The gear set is installed in the middle position of the box, and the central axis of the energy storage knob is? The gear transmission is connected to the left end of the transmission gear, which is widely used and simple to manufacture. Easy to popularize.

Introduction of energy-saving fan:
The biggest advantage of variable frequency electric fan
According to reports, at present, among brands such as Midea and Emmett, the proportion of variable frequency electric fans has reached 30%. Because variable frequency electric fans belong to high-end products, buyers are mostly middle and high-end consumers. According to reports, compared with ordinary electric fans, variable frequency electric fans are at least twice as expensive. What is unique about such a high-priced variable frequency electric fan?
"Energy-saving is the biggest highlight of variable-frequency electric fans." Miss Chen, a shopping guide for electric fans in Fuzhou Gome Baolong Store, said that variable-frequency electric fans use motors, and energy-saving is the biggest feature of motors. Take Midea's variable frequency electric fan as an example. Compared with the traditional AC motor, the 180 sine wave DC variable frequency motor adopted by it has an energy efficiency conversion improvement rate as high as 200%. Emmett, on the other hand, uses DC ⅲ high-efficiency DC motor, with the power as low as 27W, which is more than 50% less than that of ordinary electric fans with 55-60W.
In addition to saving energy and electricity, another advantage of variable frequency electric fan is its smooth operation. The shopping guide added, "Ordinary electric fans generally adopt the design of three wind speeds, and variable frequency electric fans mostly adopt the design of flexible blades and 26-speed and 32-speed stepless speed regulation, which can flexibly adjust the most suitable wind speed, including natural wind, sleeping wind and standard wind, which can make the blowing wind softer and more comfortable." In addition, the electric fan of the variable frequency motor is quieter, which can reach 17 decibels, making people rest in a very quiet environment.
price is on high side
Consumers' first choice is cost performance. Although the variable frequency electric fan has many advantages, its sales volume is a bit tepid. Many interviewed businesses admit that citizens prefer ordinary electric fans with low prices compared with "high-rise" inverter electric fans. "The price is a bit expensive. The price of five or six hundred yuan is enough to buy two good ordinary electric fans. " Mr. Liu, who chose a common floor fan, thinks that the cost performance is the primary consideration when choosing an electric fan.
Although variable frequency electric fans have not yet become the mainstream of the market, people in the industry believe that with "energy saving and environmental protection" becoming the standard index of the home appliance market, the "variable frequency" of electric fans will become the future development trend. "With the addition of more brands and the improvement of frequency conversion technology, I believe that in another year or two, the price of DC variable frequency electric fans will come down and gradually become popular." The person in charge of small household appliances in Fuzhou Suning said.
The above is an introduction to the principle of energy-saving fan compiled by Bian Xiao. I wonder if you have any new knowledge and understanding of energy-saving fans after reading it? In fact, energy-saving fans are still very practical in our daily life and can also save energy for us. These automatic energy-saving products can not only facilitate our life, but also add some fun. Interested friends may wish to buy and use it. I hope Bian Xiao's suggestion can help everyone.
