Personally, I thinkElectric fanThere are four types: table fans, floor fans, ceiling fans, and small fans; Applicable occasions: Desk fans are generally suitable for office use.
Floor fans are suitable for family dinners. Ceiling fans are generally suitable for sleeping. Small fans are generally suitable for students or personal use, which is more space-saving.
1.The working principle and use of table fans
The working principle of the table fan is that the energized coil rotates under force in a magnetic field. Ordinary household desk fans are single-phase motors.
Because the single-phase power supply cannot form a rotating magnetic field to rotate the rotor, it is necessary to establish a magnetic field that can rotate the single-phase motor in the starting circuit of the motor in series, so that the single-phase motor can be started smoothly. Desk fans are generally more suitable for home or office use, and they can be moved to a different position, which is very convenient, but they need to be placed on a flat surface.
2.The working principle and use of floor fans
Floor fans work on a similar principle to table fans, but floor fans use rotating blades to supply air. The wind power of the floor fan is relatively large, and it can be moved to the position, which is more convenient, but the floor fan is louder, and most of the blowing area is the upper body, which can only solve the local heat dissipation. Floor fans are generally suitable for family dinners or meals to relieve the feeling of heat.
3.The working principle and use of ceiling fans
Ceiling fans work on the principle of permanent magnets.
Excitation synchronous motor, because the synchronous motor is more difficult to start, so a spring must be used to help it start. Ceiling fans are generally fixed to the ceiling.
, takes up less space. However, the disadvantage of ceiling fans is that they cannot be moved. The ceiling fan is more suitable for use when sleeping, the effect is very good, and the sound is low.
4.The working principle and use of small fans
The working principle of the small fan is that the motor generates electromagnetic torque after receiving the current provided by the battery, and the motor rotates under the action of the torque, generating mechanical energy.
Turn the blades of the small fan around. The small electric fan is more suitable for going out in summer or when it is hot, you can quickly feel cool, it is more economical and energy-saving, and it is easy to carry.
In summary
Personally, I think that electric fans are divided into four types: table fans, floor fans, ceiling fans and small fans, among which small fans and table fans are the most commonly used in daily life, small fans are easy to carry, and table fans are easy to use in the office.
-
There are several types of electric fans, namely table fans, ventilation fans, bi fans, floor fans, and ceiling fans. Desk fans are suitable for offices, ventilation fans are suitable for kitchens, bi fans are suitable for restaurants, floor fans are suitable for homes, and ceiling fans are suitable for factories.

1. According to the structure of the motor, it can be divided into:
Single-phase capacitive, single-phase shaded, three-phase induction, DC and AC/DC dual-purpose series commutator electric fans.
2. According to the classification of use, it can be divided into:
Household electric fans and industrial exhaust fans.
3. Household electric fans can be divided into:
ceiling fans, table fans, floor fans, wall fans, top fans, ventilation fans, page fans, air conditioning fans (i.e. cooling fans), etc.; There are also heads of head and non-head in table fans, and there are also page fans; There are shaking heads and turning pages in the floor fan. There is also a small breeze fan, which is specially hung in a mosquito net.
Electric Fan Selection Guide:
1. Look at the random file The random file of each electric fan includes the instruction manual, product certificate, electrical circuit diagram and packing list, and the quantity and quality of parts should be checked and checked according to the packing list when purchasing.
2. See whether the net cover and fan blades are obviously deformed: on the assembled electric fan grille, use a pen to point to the highest point of a fan blade, slowly move the fan blade, and the distance between the corresponding points of the other fan blades and the pen tip should be very close, and then rotate the fan blade, pay attention to observe whether the rotation is light and flexible, and can stop at any position.
3. See whether the control mechanism is flexible: the control mechanism includes speed control switches, timing knobs, shaking head switches, lighting switches, etc., which should be flexible in operation and reliable in contact. For the speed control gear, it is not allowed to have two gears connected at the same time or one gear cannot be pressed.
Press the stop button, and each speed stop button should be reset normally.
4. Look at the performance of the active part: the fan head of the electric fan runs flexibly at all angles of pitch and tilt, locks firmly, adjusts to the maximum depression angle or shakes the head to the final position, and the grille must not touch the fan pillar. When the fan is running, the stability should be good, it should not be tipped over, and the shaking angle should not be lower than 60-80 degrees.
5. Look at the starting performance: the starting performance is an important quality indicator of the electric fan. During the inspection, it should be adjusted in the light wind gear, and when the rated voltage of the power supply is 85%, that is, the voltage regulator will be used to reduce the voltage of 220 volts to 187 volts when the electric fan is started, the electric fan should be able to start from stationary and operate normally, the shorter the time required for an electric fan from start to normal operation, the better the starting performance of the fan motor.
6. Look at the operation and speed regulation performance: after powering on, the shaking head switch will be rotated back and forth several times to check whether it is out of order or the assembly is too tight, in this process, there should be no abnormal noise in the mechanical transmission part of the fan.
When the electric fan is running in light, medium and strong winds, the motor and fan blades should be stable, with low vibration and low noise. The fan shakes head and stops quickly, without intermittent, stagnation and jitter, the speed difference between each gear should be obvious, and the larger the air supply angle, the better. When the fan stops, the axial clearance of the rotating shaft does not exceed 0 5 cm, and if the gap is too large, it will cause axial movement and impact sound during operation.
7. Check whether there is leakage: After the electric fan is powered on, if there is a strong numb inductance when touched by the hand, test it with a voltage tester, and the voltage tester will also glow and display, which can determine the leakage of the shell and cannot be selected.

With the continuous development of science and technology, the electrical appliances for cooling in summer continue to develop, from the most traditional electric fan that people are familiar with, to the air conditioner that every household must have. Although air conditioning has gradually entered the lives of ordinary people, electric fans have not been eliminated, but are constantly developing, from the traditional floor fans, table fans, ceiling fans, to the development of tower fans, bladeless fans, air conditioning fans and so on that combine new technology. So what are the different types of electric fans?
1. Floor fan: The biggest advantage of floor fan is that it can have an independent fulcrum, and there is no need to use external tables and chairs to place fans. Floor fans are commonly used in homes and factories, in addition to traditional floor fans, there are now more luxurious versions of floor fans, that is, multi-functional electronic and remote control fans, but also have silent air energy.
2. Ceiling fan: the ceiling fan blades are large, the air volume is large, and the coverage area is also large, with the development of the ceiling fan, there is now a kind of ceiling fan lamp, that is, the middle of the ceiling fan is the lamp, and the surrounding is the fan blade, which takes into account the two functions of lighting and cooling, which is very practical!
3. Desk fan: Desk fan is a kind of electric fan that people use a lot, it is small in size, covers a small area, and is easy to move.
4. Tower fan: tower fan, also known as convection fan, is smaller than the floor fan, saving space; The appearance is fashionable and beautiful, not only used, but also used as a decoration in the home; The grille of the tower fan is also relatively small, so it is not easy to accidentally injure children! The air supply effect is better, the wind is softer, and it is more comfortable!
Electric fan is almost a must-have household appliance in everyone's home, due to the development of science and technology, electric fans continue to improve, various types of electric fans appear on the market, consumers can learn more about their advantages, combined with their own situation, choose the most suitable for themselves!

1. Wall fan: It can only be hung on the wall, which is easy to use and does not take up space. If the room area is small, in order to facilitate the handling of the indoor faction, you can consider choosing a wall fan to also achieve the same cooling effect as the table fan.
Wall fan 2, platform fan: can be placed on the countertop, can also be placed on the ground for use, its height is retractable, relatively moderate.
3. Floor fan: Generally, it can only be used on the ground and occupies a certain area. Although it takes up a certain amount of space, it is highly decorative and magnificent, and can also be used as a floor lamp and a floor fan.
Floor fan 4, ceiling fan: with a hook, hang on the floor for use, large air volume, air supply range in general, suitable for collective places to make Li He use.
Ceiling fan 5, air conditioning fan: use the temperature difference between water temperature and room temperature to cool the airflow, and then blow into the room, and dress up a fan with a small amount of cooling function. It is best not to use an air conditioner fan if there are elderly people and children at home, because it is actually an electric fan equipped with a water cooling device, and the air outlet is easy to breed bacteria, and the bacteria will blow into the air with the cold wind; In addition, people with excessive humidity and poor immunity are prone to eczema, atopic dermatitis and other diseases.
If there are rheumatism patients and pregnant women's families, it is better not to do so.
The above is about the content of what types of electric fans, there are many types of electric fans, different types have different characteristics, you can buy them according to your own needs.
