Fans and air conditioners are inseparable from the heat in summer. When the weather is not so hot, fans can be said to be a must-have item to cool down. In the hot summer, the floor fan can ventilate the room, prevent heatstroke and cool down, and improve the environment. The height of the floor fan can be adjusted, and the chassis is placed on the ground, which is relatively stable. It can be divided into household floor fans and industrial floor fans.
1 Is it better to have a floor fan or a tower fan
floor fan
The fan is rotated by an AC motor, there are Large air volume, low noise, stable chassis and other characteristics, especially in summer, the indoor ventilation, heatstroke prevention and cooling effect are very obvious.
Tower Fan
Also known as a convection fan. The tower fan is derived from the principle of airflow, and is mainly used to exchange indoor and outdoor air, 360-degree convection air, so that the room feels comfortable without the dead angle of air supply.
Data talk:
1. The price of tower fans is relatively expensive, about 400 yuan. For floor fans, the prices are various, but most of them are low. For tower fans;
2. Tower fans are mainly for air convection and air circulation, while floor fans are mainly for strong wind;
3. Generally speaking, tower fans will It is relatively safe, and the floor fan is the most dangerous among the fans. It is not suitable for the elderly and children at home to use the floor fan, which is prone to accidents;
4. The tower fan is very quiet when working, the air supply is stable and comfortable, and the floor fan There is a sound, which is louder than the tower fan, the air supply is less stable, and it is easy to get dizzy when blowing against it. It is not recommended for the elderly and children to blow against it.
5. The wind blown by the tower fan basically falls on the whole body, while most of the area blown by the floor fan is the upper body.
2 Floor fan purchase
1. When unpacking and checking the product, the certificate and manual must be attached. The nameplate of the floor fan should have the manufacturer’s name, product model specification, Rated power, rated voltage, power type and frequency;
2. Appearance quality requires that the shape, line and color tone are beautiful and generous. The electroplated parts should be smooth, shiny, free of yellowing, rust, peeling and water marks;
3. Whether the decorative parts are damaged; Whether the solder joints are loose and desoldered, etc. The floor fan can be raised and lowered flexibly;
4. Check whether the floor fan’s shaking head, speed control and timing switch are consistent with the panel marking;
5. The timing device requires accurate timing, flexible rotation, and no card The normally open and normally closed positions should be controlled reliably;
6. Check the fan blade: slowly rotate the fan blade by hand, the fan blade rotates smoothly and easily, without touching any part, stop When the leaves gradually diffuse and stop naturally.
3 Floor fan installation
1, chassis installation
First install the elbow screw and Take out the pressure plate from the column, insert the column into the base, place the pressure plate on the lower part of the chassis, and tighten it clockwise with the elbow locking screw.
2. Integral installation
(1) Loosen the lifting lock nut first, and pull the lifting pipe from the column out, and then use the lifting lock nut to lock the goods.
(2) Loosen the clamp nut at the lower part of the fuselage, insert the fuselage into the lift pipe, and tighten the clamp nut.
(3) Loosen the lifting lock nut, adjust to the required height, and tighten the nut.
3, install the rear grill
Unscrew the fan blade fixing nut from the motor shaft, then unscrew the triangular nut, and then Install the rear grille.
4. Installing the fan blades
When installing the fan blades, the groove behind the fan blades should be stuck in the motor. on the stop pin, and then tighten the fixing nut counterclockwise.
4 Floor fans are safe to use
Do not use them in places where they are easily sucked in, such as curtains.
It is absolutely forbidden to insert hands or foreign objects into the grille during operation, which may cause injury or damage.
Be sure to pull out the power plug when not in use for a long time.
It is strictly forbidden to use the power plug without assembly.
Turn off the power before pulling out the plug, do not pull the power cord, but pull out the power plug, otherwise it will cause short circuit and electric shock.
Do not move the fan when it is turned on, and do not change the orientation by hand when shaking the head automatically, so as not to damage the shaking mechanism.
5 Cleaning and maintenance of the floor fan Remove it. There are cards around the protective net. After loosening the card, unscrew the screws to take off the protective net.
2. Next, remove the fan blade, unscrew the round plastic cover in the middle of the front of the fan blade, you will see a small section of shaft exposed, hold the leaf and tap the shaft fan blade with a small hammer just took it away. Different models of electric fans have slightly different designs, and some need to remove the small screws on the side of the fan blades.
3. Mix detergent, washing powder, dishwashing liquid and other cleaning agents with water, soak the protective net in the washing liquid for 10 minutes, then clean it with a brush, and wipe it with a dry rag Dry, dry.
4. Fan leaves are generally made of plastic, so do not use hairy oils to wipe them. Use a sponge dipped in lotion to carefully wipe off the dust and dirt, and then wipe it off with a wrung cloth to dry in the shade.
5. When removing the fan, generally do not touch the timer, let alone remove the timer. Because the timers used for electric fans are assembled with special equipment or tools, once disassembled, it is difficult to restore.
Maintenance of floor fan
1. In high temperature weather, use floor fan for 2-3 hours and then rest for a while before continuing to operate to avoid Motor overheated and damaged.
2. During use, please do not place your hands or branches in the fan blade area to avoid personal injury and damage to the floor fan.
3. The floor fan should be placed stably when in use, and there should be no obstacles within the range of the electric fan.
4. When the floor fan has been used for a long time, if you smell an odor or make an abnormal noise from the electric fan, you should immediately turn off the power and check.
5. The floor fan should add a little lubricating oil every 3-5 months, and the shaking part should be cleaned every 3 years.
6. Place it in a moisture-proof and sun-proof area. If it is not used for a long time, it can be packed in a carton and placed in a dry area.
6 Floor fan repair
1, floor fan shaking head failure
Repair method: check Whether the shaking of the floor fan is blocked by external force, causing its connecting rod to bend, if the external force is blocked and the shaking of the head fails, it will emit a “drip” bluntness. Another possibility is that the rotation fails, so that the power cannot be obtained, so the shaking of the head fails.
2, the fan does not rotate
Maintenance method: when the fan of the floor fan stops rotating, use a multimeter to measure the main The coil is open, and its line is usually behind the bolts of the rear cover. After finding it, you can use a multimeter to test both ends of the fuse. If the circuit is open, it means that the coil is good. If the fuse is not replaced, you can remove the fuse and weld the two ends Together, the insulation work is done at the same time, and the electric fan can be operated at the same time.
3, the electric fan does not turn
Maintenance method: it does not turn mainly because its bearing lacks oil, The fan blades can be removed, dripped with oil and can be turned.
