A ventilation fan, also known as a ventilation fan, is a common household appliance that can not only remove unclean gas from the kitchen, but also draw in fresh air to create a suitable indoor environment. The production of ventilating fans is related to the humid weather in coastal areas. When working, the motor is used as power to drive the fan blades to rotate, and then rotates in different ways to discharge and inhale the gas. Let’s take a look at the encyclopedia of the ventilator with me.
1 What is a ventilation fan
A ventilation fan is composed of ancillary components such as electric motor, fan blade, air frame, panel, etc. It is generally installed in the kitchen or bathroom, mainly used to remove the dirty air in the room and inhale fresh air, thereby To achieve the purpose of adjusting temperature and humidity. The ventilation fan is driven by the motor to drive the fan blades to rotate to drive the airflow. The ventilation methods include exhaust 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 sucks in fresh air through the ventilation fan, and discharges the dirty air from the natural exhaust port. The combined type is that the suction and exhaust are both completed by the ventilation fan.
2 The working principle of the ventilating fan
The ventilating fan is driven by the motor to drive the fan blades to rotate to drive the airflow, so that the indoor and outdoor air can be exchanged. The exhaust type enters the air from the natural air intake, and exhausts the dirty air through the ventilation fan. The suction type sucks in fresh air through the ventilation fan, and discharges the dirty air from the natural exhaust port. The combined type is that the suction and exhaust are both completed by the ventilation fan.
3 How to install the ventilating fan
1. Ceiling type
1. First make the vent hole, the diameter of the vent hole should be slightly shorter than that of the ventilating fan. Due to the need to take gold and steel holes on the wall, it is best to ask a professional master to do it.
2. Do a good job of switch wiring, usually on the multiple sets of switches beside the bathroom door, one of which is to control the ventilation fan. If it is a separate ventilation wiring, it is relatively simple to directly connect the two reserved wires to the two wires of the ventilation fan.
If it is heating, shifting, or synthesizing, it is recommended to directly use the control switch provided by the original manufacturer, and properly connect the wire of the original switch to the reserved wire. If no dark lines are reserved, the open lines can only be run in the form of wire grooves.
3. After the previous work is done, remove the ceiling piece and replace the original position with a ventilation fan. The wiring method is very simple. The current ceiling-type ventilator generally occupies the area of a ceiling piece.
Second, vertical window type
1. When purchasing, measure the installation size in advance and plan the installation location. If the aluminum alloy window is used, it can be considered to be installed directly on it and fixed in the form of drilling holes and self-tapping screws. In order to be more firm, you can also add an aluminum bar yourself.
2. Reserve dark lines, if not, you can arrange open lines on the wall in the form of wire troughs, or use the method in parallel with the lighting.
3. Generally, there are only two wires, live wire and neutral wire, for wiring, which is very simple. The strong and weak gears are mainly controlled by mechanical wiring switches, and one does not need to be controlled. Note that the wiring should be made of insulating tape and waterproof.
Three, wall-mounted type
1. First, open a mounting hole on the wall, the size of the hole is slightly smaller than that of the ventilation fan.
2. Use an electric drill to drill holes around the mounting holes and insert plastic expansion pipes. The number and location of holes are the same as for the ventilator bracket.
3. Apply force from the side and open the buckle to separate the ventilating fan panel from the bracket. 4. Install the bracket into the mounting hole and lock the self-tapping screw to ensure that it will not shake.
5. Snap the ventilating fan panel and the bracket together, cover the panel, and connect the power supply.
4 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 unplug the power supply with wet hands.
2. Prepare a neutral cleaning agent and dilute it with a small amount of warm water. If there is oil stains, have hot water and dish soap ready.
3. Use a screwdriver to remove the screws on the outer surface of the exhaust fan, remove the casing, and then take off the exhaust fan blades and filter.
4. After removing the exhaust fan blades and filter, soak them in the prepared cleaning solution, and then use a brush to clean the fan blades and filter. If there is too much oil, wash it with hot water and detergent, or with alkaline water.
5. Dry the cleaned fan blades and filters, and place them in a ventilated place for later use.
6. Use a rag soaked in cleaning solution, then wipe the vents and other stained parts.
7. Put the dried fan blades and filter back on the exhaust fan, then fasten the casing and fasten the screws.
8. After the power-on test, the exhaust fan is light and the noise is low, which means that we have successfully cleaned the exhaust fan. If there are other problems, you should check the installation step by step for errors.
5 The difference between a ventilation fan and an exhaust fan
1. Different functions
The exhaust fan is driven by a motor to make the fan blade rotate, so that the indoor It can be exchanged with outdoor air, but it can only be partially exhausted, not air intake, and indoor and outdoor air cannot be circulated.
The motor of the ventilating fan usually has two directions, which can not only discharge the turbid indoor air, but also suck in a large amount of fresh air from the outside, so as to achieve indoor air circulation.
2. Different installation positions
The exhaust fan will make a lot of noise during operation, and the length of the pipeline will be weakened during the operation. Therefore, it is usually installed in the kitchen or bathroom, and cannot be installed in the bedroom, nursery room, elderly room, etc., which will affect our normal rest.
The ventilation fan has low noise and good air circulation. It can be installed not only in kitchens and bathrooms, but also in bedrooms, living rooms and other environments that require quiet.
3. Different prices
The exhaust fan has a single function, and its price is relatively cheap. The ventilation fan has many functions. In addition to the suction and exhaust function, it may also have functions such as heating, lighting, etc., so its price is relatively expensive.
6 How to choose a ventilating fan
1. Look at the appearance
It should be selected with a novel appearance, a color coordinated with the color of the room, no warping on the plane, and plastic parts A ventilating fan that is flat and smooth, the electroplating parts are bright, and there is no trace of rust.
2. Look at the performance
After the power is turned on, the fan blades rotate smoothly, there is no abnormal noise, and the air volume is large. The self-blowing shutters are flexible and movable, the interlocking shutters are flexible in rotation, and the two-way ventilation fans 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 the speed regulation function is obvious.
3. Look at the fan blade
The fan blade is an important component of the ventilation fan. If the quality is not good, it will have a great impact on the later use. Therefore, choose When purchasing, remember to identify the quality of the fan blades, mainly to check whether the design of the fan blades is correct, whether there is deformation, etc.
4. Look at the ventilation volume
The ventilation volume of ventilation fans of different sizes and powers is also different, so when you buy, you should If you actually need to buy it, you can also refer to the ventilation fan manufacturer’s manual to buy it.
5. Look at the safety signs
When purchasing a ventilation fan, you must check whether the product has 3C certification, and check the product name, specification, voltage and other signs Whether it is complete, whether there is a certificate of conformity, etc.
6. Look at the brand
The quality of the ventilation fans of the big brands is guaranteed and the after-sales service is good, while the quality and after-sales service of the products of the small brands are difficult to be guaranteed. Therefore, consumers should not buy Sanwu products for the sake of cheapness.
