How to blow the fan is healthier, and how to blow the fan is the most reasonable

Healthy use of electric fans.

1. Place it correctly.

To use the electric fan healthily, the fan should be placed correctly and the distance between the electric fan and the human body should be controlled. The placement of the electric fan should be about 2 meters away from the human body, and the wind blowing out is soft and even.

If the wind blows too closely, the gap between blood circulation and sweat circulation will be too large, and the nerve center will lose balance, and if the time is too long, the organs of the human body will feel tired and cause general discomfort.

How to turn on an electric fan to be healthier, these tricks should be taken a look.

2. Control the wind speed.

The wind speed of the electric fan should not be too large, the indoor wind speed is controlled in meters, and the wind speed of the electric fan can be appropriately reduced in the room with better ventilation and the place where there is excessive wind.

3. Direct blowing is prohibited.

Especially when the body is weak or sweating, it is best to let the fan blow to a corner, rather than blowing directly on the human body.

For the elderly, the weak, the sick and the young, less electric fans are used to blow the air, and only electric fans are used to adjust the indoor airflow to achieve the purpose of indirect cooling.

Special attention should be paid to not being able to directly approach the electric fan when sweating profusely, which will hinder the perspiration of the body surface, destroy the circulatory system of the human body, and easily cause stroke.

4. Control the use time.

Control the use time of the electric fan, and do not turn on the electric fan for a long time to avoid discomfort. Suggestion: It is better to turn on the fan for about 1 hour at a time.

If you use the fan for a long time, the temperature of the human body will decrease with the evaporation of sweat, and it is easy to cause symptoms such as colds, abdominal pain, and diarrhea over time.

5. Control the air volume.

Control the airflow of the electric fan, especially when sleeping, and do not overdo it.

When a person is sleeping, the circulation of the human body slows down, the air volume is too large, and it blows directly in front of the person, which will cause symptoms of fatigue, and in severe cases, stroke will occur.

Swing wind, in this way to avoid blowing in one direction for a long time, resulting in cold damage to the body.

If you look up and blow up, you can raise the fan and blow the wind on the roof, and then the wind will be reflected back through the roof.

Blowing on the side allows the fan to blow the wall on the side, and the wind reflected back through the wall will be softer and less likely to cause physical discomfort.

When blowing a fan, you can't blow it for a long time, and when you are sleeping, you can't blow a fan. When I sleep, the fan is in trouble, and the fan is easy to catch a cold and get rheumatic diseases.

As follows:

1. First of all, the electric fan should keep a certain distance from the person, and must not go out and return to the door to blow wildly with the electric fan, the appropriate distance should be the diameter of the electric fan multiplied by 9 for a better distance, of course, it is also necessary to make appropriate adjustments according to the wind speed and mode of the electric fan.

2. Try to choose an electric fan with the function of "shaking head", which can not only avoid the direct blowing of the wind for a long time, but also promote the air circulation in the house, which helps to reduce the overall temperature of the room.

3. Don't blow the fan for more than 1 hour in a row, of course, this is a bit difficult for the majority of friends, but blowing on the fan for a long time can easily cause a cold.

4. Turn on the sleep mode when sleeping, blowing the fan at night is easy to cause disease, such as the above example is the tragedy caused by improper use at night, the sleep mode can well control the wind speed and volume, and stop the station when appropriate, which is a state close to the natural wind, and the impact of this softer wind on the human body will be greatly reduced.

Tips for using electric fans:

1. Select. When purchasing, you should choose products with excellent quality. Due to the low technical threshold of the fan industry and the uneven products on the market, it is necessary to choose brand products, which can ensure the quality.

2. Gear. Make reasonable use of the electric fan gear. The difference between fast and slow power consumption of the same electric fan is about 40, and the power consumption of 1 hour on fast gear can be used for nearly 2 hours on slow mode. Therefore, when just starting, it should be in the high-speed gear, and after reaching the rated speed, it should be changed to the medium-speed gear or low-speed gear, which is conducive to the rapid start of the motor, so as to achieve the purpose of protecting the motor.

3. Work efficiency.

Improve the efficiency of electric fans. When using an electric fan, it should be placed in a relatively cool place indoors, so that the cool breeze blows to a higher temperature; Place the fan in the corner of the house during the day to allow the indoor air to flow outside; At night, move the fan to the inside of the window to blow the cold air from the outside indoors, or blow the fan in the direction of the downwind to improve the cooling efficiency and shorten the time of using the fan, so as to reduce the power consumption.

4. Maintenance. Pay attention to the maintenance of the fan, maintain its good performance, and avoid the deformation and vibration of the fan blades, which is also conducive to the saving of electric energy to a certain extent.

1. Modern science believes that the indoor wind speed is best controlled at 0 2-0 5 meters per second, especially in the well-ventilated room and in the place where there is excessive wind, the wind speed of the electric fan should not be too large.

In addition, when the temperature exceeds 30, do not choose too large a windshield, because the wind blowing from the fan is also hot. The human body mainly relies on sweat evaporation to dissipate heat, if the fan blows too much, the surface temperature drops, the pores are occluded, and the sweat inside the body cannot be released, not only will it feel hot, but also fatigue and weakness, back pain, which is "sweating".

2. Blowing directly, the wind evil is easy to invade the body, especially when the body is weak or sweating profusely, it is best to let the fan blow towards a corner;

For children, the elderly, and people who are weak, it is better to use less electric fans to blow the air, because "where the evil is, its qi will be empty", but you can use an electric fan to adjust the indoor airflow, so as to indirectly cool down.

3. It should be noted that when there is a lot of sweating, do not immediately blow the wind in the situation of sitting or lying still, because at this time, the blood vessels on the surface of the whole body are dilated, and the sudden cool breeze blows will often cause the blood vessels to constrict, and the sweating will stop immediately, resulting in the loss of balance between heat production and heat dissipation in the body, and the excess heat can not be excreted.

After the cool breeze blows, the local defense function decreases, and viruses and bacteria invade, which can produce upper respiratory tract infection, muscle and joint pain, and some even abdominal pain and diarrhea.

4. Because the fan can directly convert electrical energy into kinetic energy, the power consumption is very low, and the maximum power delay rate is only 60W, which is equivalent to the power consumed by ordinary lighting table lamps. Therefore, from the perspective of energy saving, using a fan in the middle of summer is undoubtedly the best choice. When the fan is used with the air conditioner, and the air conditioner temperature is set at 26 degrees to 28 degrees, the potato potato only saves electricity and money.

5 As far as the use of the fan itself is concerned, it generally refers to the fan with large fan blades, the electric power is large, and the power consumption of the electric fan is proportional to the speed of the fan blades, such as the 400 mm electric fan, the power consumption is 60W when using the fast gear, and the power consumption is only 40W when using the slow gear, and the power consumption of the fastest gear and the slowest gear of the same electric fan is 40%, and the power consumption of 1 hour on the fast gear can be used for nearly 2 hours on the slow gear. Usually turn on the fast gear first, and use the slow gear more after it cools down, which can reduce the power consumption of the electric fan. Qi or.

6. When in use, the fan should be placed next to doors and windows. In this way, it is easy to circulate air, improve the cooling effect, shorten the use time, and reduce power consumption.
