Ventilation fan, also known as ventilation fan, is a common household appliance, which can not only remove unclean gas in the kitchen, but also pump in fresh air, thereby creating a suitable indoor environment. The generation of ventilation fans is related to the humid weather in coastal areas, working with the motor as power, driving the blades to rotate, and then rotating in different ways to discharge and inhale the gas, and then take a look at the encyclopedia of ventilation fans with Xiaobian.
First, what is the ventilation fan
The ventilation fan is composed of motors, fan blades, wind frames, panels and other auxiliary components, generally installed in the kitchen or bathroom, mainly used to remove indoor dirty air, inhale fresh air, so as to achieve the purpose of adjusting temperature and humidity. The ventilation fan is driven by the motor to drive the fan blade to rotate to drive the airflow, and its ventilation methods include three types: discharge type, suction type, and combined type. The exhaust type enters the air from the natural air intake and exhausts the dirty air through the ventilation fan. The suction type draws in fresh air through a ventilation fan and discharges dirty air from the natural exhaust port. The combined use is that both the suction and exhaust are completed by the ventilation fan.
Second, the working principle of the ventilation fan
The ventilation fan is driven by the motor to drive the fan blade to rotate and drive the airflow, so that the indoor and outdoor air is exchanged, and the ventilation method is three types: discharge type, suction type, and combined type. The exhaust type enters the air from the natural air intake and exhausts the dirty air through the ventilation fan. The suction type draws in fresh air through a ventilation fan and discharges dirty air from the natural exhaust port. The combined use is that both the suction and exhaust are completed by the ventilation fan.
Third, how to install the ventilation fan
Ceiling type
1. First of all, the exhaust hole should be slightly shorter than the ventilation fan. Since it is necessary to make gold steel holes in the wall, it is best to ask a professional master to do it.
2. Do a good job of switch terminals, generally on multiple sets of switches next to the bathroom door, one group is to control the ventilation fan. If it is a separate ventilation wiring is relatively simple, directly connect the reserved two wires to the two wires of the ventilation fan. If it is heated, shifted, or synthesized, it is recommended to directly use the control switch provided by the original manufacturer to properly connect the wire of the original switch with the reserved wire. If there is no reserved dark line, it can only be in the form of a trunking and walk the bright line.
3. After the previous work is done, remove the ceiling sheet and replace the original position with a ventilation fan, and its wiring method is very simple. Today’s ceiling ventilation fans generally occupy the area of a ceiling sheet.
Window inline
1. Measure the installation size in advance and plan the installation location when purchasing. If aluminum windows, you can consider installing them directly on them, fixing them in the form of drilled holes and self-tapping screws. For more solidity, you can also add an aluminum strip yourself.
2. Reserve the dark line, if it is not reserved, you can arrange the bright line on the wall in the form of a trunk, or use the way of parallel with the lighting.
3. The wiring is generally only two wires, live wire and zero line, very simple, the strong and weak gears are mainly controlled by mechanical wiring switches, and one does not need to be managed. Note that the wiring should be made of insulating tape and waterproof.
Wall-mounted
1. First open a mounting hole in the wall, the size of the hole is slightly smaller than the size of the ventilation fan.
2. Holes will be drilled with electric drills around the installation hole, and plastic expansion pipes will be stuffed. The number and location of holes is the same as that of the ventilation fan holder.
3. Apply force from the side, open the buckle at the top, and separate the ventilation fan panel from the bracket.
4. Put the bracket into the mounting hole and lock the self-tapping screw to ensure that it will not shake.
5. Card the ventilation fan panel and bracket together, cover the panel, and connect the power supply.
Fourth, how to clean the ventilation fan
1. Gently unplug the power supply of the exhaust fan, be careful when unplugging the power supply, and do not use wet hands to pull the power supply. 2. Prepare a neutral detergent and dilute it with a small amount of warm water. If there is oil, prepare hot water and dish soap. 3. Use a screwdriver to remove the screws on the outer surface of the exhaust fan, remove the shell, and then remove the exhaust fan blades and filter screen. 4. After removing the exhaust fan blades and filter screen, soak them in the prepared cleaning liquid, and then brush the fan blades and filter screen with a brush. If there is too much oil, wash it with hot water and dish soap, or you can wash it with alkaline water. 5. Dry the brushed fan blades and filter screen, and place them in a ventilated place for later. 6. Soak a rag with cleaning solution, and then wipe the vents and other stained parts. 7. Put the dried fan blades and filter screen back into the exhaust fan, and then buckle the shell and screw well. 8. Power on test, the exhaust fan is light and the noise is small, which means that we clean the exhaust fan successfully. If you have other problems, you should check the installation step by step for errors.
Fifth, the difference between ventilation fan and exhaust fan
1. The function is different
The exhaust fan is started by the motor to rotate the fan blades, so that the indoor and outdoor air are exchanged, but only local exhaust air, no air intake, indoor and outdoor air can not be circulated. The motor of the ventilation fan usually has two steers, which can not only discharge the turbid air in the room, but also inhale a large amount of fresh air outside to achieve indoor air circulation.
2. The installation location is different
The exhaust fan will make a large noise during operation, coupled with the length of the pipeline during the work process weakens the exhaust force, so it is usually installed in the kitchen or bathroom, and cannot be installed in the bedroom, nursery, elderly room and other places, which will affect our normal rest. The ventilation fan has low noise and good air circulation, and it can be installed not only in kitchens and bathrooms, but also in bedrooms, living rooms and other quiet environments.
3. The price is different
The exhaust fan has a single function and is relatively cheap. The ventilation fan has more functions, in addition to the suction and exhaust function, there may be heating, lighting and other functions, so its price is relatively expensive.
Sixth, how to choose and buy ventilation fans
1. Look at the appearance
A ventilation fan with novel appearance, color and room color coordination, no warping phenomenon, smooth plastic parts, bright electroplated parts, and no rust marks should be selected.
2. Look at the performance
After powering on, the fan blades rotate smoothly, there is no abnormal noise, and the air volume is large. The self-blowing shutter window is flexible and movable, the linkage shutter rotates sensitively on all sides, and the two-way ventilation fan can be converted freely. The temperature rise of the motor is not too high, and the noise is small. The speed regulation effect of the ventilation fan with speed regulation function is obvious.
3. Look at the fan blades
Fan blade is an important component of the ventilation fan, if the quality is not good, the later use has a great impact, so, when purchasing, remember to identify the quality of the fan blade, mainly to see whether the fan blade design is no problem, whether there is deformation, etc.
4. Look at the amount of air exchange
The amount of ventilation of ventilation fans of different sizes and different powers is also different, so when you buy, you should choose according to your actual needs, and you can also refer to the fan manufacturer’s manual to buy.
5. Look at the safety sign
When purchasing a ventilation fan, you must see whether the product has 3C certification, see whether the name, specification, voltage and other signs of the product are complete, whether there is a certificate of conformity and other certificates.
6. Look at the brand
The quality of ventilation fans of large brands is guaranteed, the after-sales service is good, and the quality and after-sales service of small brand products are difficult to guarantee, so consumers should not buy three-nil products for the sake of greed.
