What electric fan is silent?
1, Midea Air Conditioning Fan
The wind blown by Midea air conditioner is not as rigid as ordinary electric fans, but relatively soft, which will make people feel very comfortable. Moreover, the multi-blade design makes the wind delicate and soft, and will not make people feel irritated like ordinary fans.
Without the design of water chestnut, people will feel very comfortable both in touch and vision. If there is a child at home, there is no need to worry that he will put his hand in or those sharp water chestnuts will hurt him.
Its mute secret is: use good motor, high seal and aviation lubricating oil. Another popular function is that it has negative ion evolution function, which can reduce the dust floating in the air, make people feel comfortable and feel the air is fresh. In this era of frequent smog, this is not the best of both worlds.
2, the student dormitory quiet small fan
Both college students and high school students should like this small fan very much. In fact, there are many bedrooms without air conditioning, or with air conditioning but only one ceiling fan. When you don't want to turn on the air conditioner, the wind of a fan is definitely not cold enough and noisy. At this time, we need a quiet small fan, which has the function of splint and can be clamped anywhere, and its small fan blades are very soft, so you are not afraid to cut your hand, even if you touch it. As for its charging, don't worry, it is everyone's responsibility to protect the environment, so it is not the battery but the wire. I like such a beautiful and practical mute fan.
3. Vaneless fan
The bladeless fan is also called the air multiplier, because it has no blades, which is easy to clean and won't hurt the fingers of curious children. Its airflow is soft, similar to natural wind, without the feeling of traditional fan flapping. It is very suitable for the elderly, children and pregnant women.
How to choose a silent electric fan
1. To judge the quality of plastic parts, it is best to choose white as the main color of the mute fan. It must be white from injection molding, not white from oil injection. When buying, you can judge by observing whether the color inside and outside the product is consistent. Because white products must be produced with raw materials, while color sprayed products can be produced with second-hand materials (waste), and then painted with color to cover up the inferior quality of plastic products. Most of the mute fans above 100 on the market are painted. You can check them. This method can also be used to buy other pigment products. Plastic raw materials are about twice as expensive as second-hand materials.
2. Determine whether it is a brushless motor or a brush motor, and check whether there is black powder on the edge of the air outlet gap. Pay attention to whether it is black. If there is black powder on the edge, it means that the manufacturer uses the silent fan produced by the carbon brush motor, and the carbon brush silent fan will constantly wear the carbon brush and blow out black powder during operation. The life of this brush motor is generally below 2000 hours, which means that if you use 10 hours every day, the motor will be scrapped after half a year. The real silent fan needs a brushless motor, which needs to be driven by a numerical control chip, and there is no life limit. If the machine can be disassembled for inspection, products without a drive board (not a control board with functions such as switch, wind speed adjustment and remote control) must use a brush motor. The real mute fan has a relatively large drive board, switch and other function control boards. Brushless motor is about twice as expensive as brush motor. Moreover, the price of sine wave driving board of brushless motor is around 50 yuan, which means that brushless motor and driving board are more expensive than those with brushes by about 70 yuan.
3. Check whether there is flour smell, turn the mute fan to the maximum wind speed, and smell the blowing wind with your nose to see if there is any peculiar smell (toner smell). If there is a smell, there must be a brush motor. You can't be fooled.
4. Check whether there is high-frequency noise to adjust the wind speed of the mute fan, and put your ears close to the air inlet to listen to the sound carefully. If there is obvious motor sound (high-frequency sound), it means that the driving board used by the fan is not sine wave, but square wave, and the quality is not up to standard, and the longer it takes, the louder the sound will be.
