Which side of the kitchen ventilation fan is windier? Whether to install a ventilation fan or an exh

Hello! Whether you are equipped with metal or plastic, Langneng exhaust fan reminds you that if it is metal, there is wind on the side of the blade, and if it is plastic, there is wind on the side of the motor.

It's metallic.

It's plastic.

As long as it is not very sealed, the exhaust fan has ventilation, and fresh air will come in, and the air is pervasive, so if there is out, it will come in again.

Langneng ventilation fan also kindly tells you that if there is a range hood, you can not exhaust the smoke You can also choose a new exhaust fan, if it is matched with the range hood is a very real and easy to use match, that is, in the middle of the exhaust pipe and the air outlet of the range hood to install an FD blower.

This works very well, this is a proposal for you, you refer to it, thank you!

Measure the size of the installation position, and then buy a suitable ventilation fan according to the size, and fix it with fixing screws.

When installing an exhaust fan, the shortest and straightest way should be used in the exhaust duct to enhance the exhaust effect. The exhaust of the bathroom on the second floor of a two-storey house and the main floor of the bungalow is easier to deal with, the exhaust fan is installed directly on the ceiling, and the exhaust pipe leads straight up through the attic to the roof, so that the moisture and odor from the interior can be directly discharged from the outside. This method is the most ideal for exhaust gassing.

Some exhaust fans are mounted on the wall and can undoubtedly expel moisture directly from the house, but they are not as effective as exhaust fans mounted on the ceiling because the warm and humid air rises upward. Therefore, when conditions permit, the exhaust fan should be installed on the ceiling as much as possible.

Installation steps for exhaust fans:

1. The installation of the exhaust fan must be reliable and firm, and the distance between the exhaust fan and the ground is more than one meter.

2. The distance between the exhaust fan and the roof must reach more than 5 cm.

3. Remember that the ceiling exhaust fan should not be installed in a place with a lot of oil smoke and dust, and should leave the high temperature source.

4. The wall exhaust fan with fan can not only ventilate in various places, but also can be used for extraction fumes.

5. Remind everyone that when using the socket for power supply, the power cord of the exhaust fan should be matched with a plug that meets the safety standards.

6. The yellow and green two-color wires in the power cord of the exhaust fan must be grounded.

7. The power supply of the exhaust fan should be connected to the all-pole switch as much as possible.

8.Finally, we remind everyone to avoid the backflow of gas through open airways and other pyrotechnic equipment channels.

In the case of ventilation fans, theoretically, the wind in the back should be greater, but considering that some brands of ventilation fans now have the functions of ventilation and air intake at the same time, so you can see if it is reversed, and there is no ventilation in the back, which will definitely affect the ventilation effect.

First of all, it should be noted that some ventilation fans are exhaust in both directions, do not open the opposite, if the ventilation behind is not good, the reclamation is to affect the effect of the ventilation fan

1. The fan is reversed or the electrodes are reversed. Specific solution: first check whether it is installed in reverse, and if it is excluded, check the wind direction transfer switch.

If there is no such switch, it is likely that the electrodes are connected in reverse. It's best to find a professional electrician to take a look. It is dangerous to repair it yourself.

2. The exhaust fan rotates outwards to make the speed of the outside air fast, and the pressure at the fast air speed is small, so that the outside air blows to the inside.

Causes the kitchen exhaust fan to blow the wind direction inside:

1. The fan is installed in reverse or the electrode is reversed. Specific solution: first check whether it is reversed, and then check the wind direction of the transfer switch, if there is no switch, it is likely that the electrode is reversed, it is best to find a professional electrician to take a look.

It can be dangerous to repair it yourself.

2. The exhaust fan rotates on the outside, so that the flow rate of the outside air is fast, and the pressure in the place where the air flow rate is fast is small, so that the outside air blows inside.

The main reasons for blowing in the wind direction are: the fan is reversed or the electrodes are reversed.

Specific solution: first check whether it is installed in reverse, and then check the wind direction of the transfer switch, if there is no switch, it is likely that the electrode is reversed, it is best to find a professional electrician to help you take a look.

Is it the wrong face of the fan? If you install the wrong surface, it will be like this, and there are some kitchen exhaust fans that are 2 functions, one blowing and one suction, you see if the switch is there.

It may be that the motor cable is reversed, causing the smoke exhaust fan to be turned into an electric fan, or the fan blades may be half installed in the opposite direction, resulting in the direction of the airflow inward. Thirdly, the middle emission light is bent excessively, and the exhaust airflow is not smooth. Eliminating the 3 reasons one by one should be solved. Hope it helps.

1. Wrong installation;

2. The exhaust fan in the kitchen exhausts the fumes to the outside, how can it be possible to exhaust the air inward.

The landlord should have installed the front and back of the fan blades of the exhaust fan upside down, and you should be able to disassemble it and reverse it.

1. Check whether the fan is installed indoors or outdoors, and adjust and reinstall it if it is wrong. 2. The wire (live wire-neutral wire) can be replaced.

If the fumes cannot be discharged, the fan is generally reversed; If it doesn't work, the line is reversed, just change it.

Drive fresh air into the kitchen, and roll out the smell of oil smoke in the kitchen to achieve air convection.

Is the kitchen in the home or the large kitchen of the unit hotel?Generally, the fan in the large kitchen is 380V, and if it is blown upside down, the line is reversed, and two of the lines can be replaced.

If it's the window-type kind, pull the switch cord again. It can be reversed.

If the blades of your exhaust fan are reversed, just change the blades to the other direction.

The machine is reversed, or the blade is reversed, or it is time to clean it.

Blowing outward is the right solution.

Kitchen exhaust fan is a kind of air conditioning appliance that drives the fan blades of the exhaust fan to rotate through an electric motor to drive the air flow in the kitchen, so that the air in the kitchen can be exchanged. That's why we also call it a kitchen fan. The kitchen exhaust fan has a large air volume, low air volume, low noise, low energy consumption, stable operation, fast exchange air flow speed and high efficiency.

The fan blades in the kitchen exhaust fan also provide a protection against dust and water.

The kitchen exhaust fan will reduce the air pressure in the kitchen while expelling the air to the outside, so the air in the kitchen will become thin and create a negative pressure zone. In this way, the air from the outside will flow into the room due to the difference in air pressure. The above is the principle of physical air pressure.

In addition, some kitchen exhaust fans also have the function of cooling, and the cooling principle is the principle of keeping the temperature equal.

Hope it helps.

Kitchen exhaust fan is a kind of electrical appliance installed in the kitchen to eliminate oil smoke, and it can be seen in many kitchens. Many people will have a question, whether the kitchen is equipped with ventilation fans or exhaust fans, don't worry, it will be revealed to you soon. 1. Installing ventilation fans or exhaust fans in the kitchen For the kitchen, the main role is to exhaust the air, so it is enough to install an exhaust fan with a large air volume.

As the name suggests, the exhaust fan is to exhaust the gas, which mainly refers to the indoor odor, moisture, oil smoke, smoking smoke and other filthy gases, from indoor to outdoor, if the exhaust fan stops working, the fan blades will not merge. 2. Whether to install a kitchen exhaust fan 1. If the kitchen area is relatively small and there is already a range hood with a large exhaust system, then it is not necessary to install a kitchen exhaust system. 2. If the kitchen is relatively large, more than 10 square meters, you can consider installing a kitchen exhaust fan to improve the exhaust effect.

3. In summer, if the kitchen is equipped with an exhaust fan, it can reduce the temperature of the kitchen when cooking. 4. When stir-frying, the oil smoke will be bigger than everyday, if there is an exhaust fan here, with the use of the range hood, there will be a better ventilation effect. 5. The exhaust fan is more energy-saving, when making soup or boiling water, only the exhaust fan can be turned on without turning on the range hood, saving electricity.

Combined with the above points, it can be understood that if the kitchen has been installed with a range hood, and the kitchen area is not large, there is no need to install an exhaust fan. The kitchen exhaust fan is easy to install, cheap, and the effect will not be very bad, and installing one in the kitchen can increase the exhaust effect, which is still a good choice. Therefore, whether to install a kitchen exhaust fan depends on your specific needs.

Summary: The above is all the content introduced about the installation of ventilation fans or exhaust fans in the kitchen, for your reference, I hope to help friends in need. I think you also know something after reading it!

Do the math how much it will cost you to renovate your home

1. When you buy a kitchen ventilation fan, you must first determine whether the product is produced by a regular manufacturer, and it is best to choose a ventilation fan produced by a big brand. Then look at the performance of the ventilation fan, which is also a major aspect of the quality of the first-line ventilation fan, mainly to see the size of the exhaust air volume and the ability to continue to operate, of course, we should also pay attention to whether its power cord is in good condition, whether the noise is large or not, and other details.

2. The manufacturers, models and brands of kitchen ventilation fans are different, so there are certain differences in kitchen ventilation fans, which are generally between tens of yuan and hundreds of yuan.

3. The ventilation fan is marked with the manufacturer, stable power, specification and "CCC" symbol in the obvious position, when we buy the kitchen ventilation fan, we should see whether the ventilation fan is complete, and at the same time see whether the ventilation fan has a certificate, instructions and packing list, and the quality of the ventilation fan with these logos is more guaranteed.

4. When purchasing a ventilation fan, you should conduct a power-on test on the collapsed sail fan next to the ventilation to see whether the ventilation fan can operate normally after being connected to the power supply, and at the same time listen to whether the ventilation fan will make abnormal sounds during operation.

It is recommended that when you buy a ventilation fan, it is best to choose a big brand of hail fan, because the quality of the big brand ventilation fan is relatively better.

1. Look at the appearance: If the ventilation fan is a metal shell, you should also pay attention to whether the paint surface of the shell is good, whether there is corrosion, rust spots and other phenomena. Also, observe whether the power cord is in good condition.

The inclination angle of the fan blade is uniform; The shutter components of the shutter should be opened and closed freely, flat, etc. The shell of the household exhaust fan is a more important problem, and the exhaust fan is relatively good in terms of materials and workmanship, and there will be no thin materials, uneven joints, deformation and damage.

2. Look at the power cord: whether the power cord is in good condition and whether there are signs of use. The inclination angle of the fan plate is uniform, and if there are blinds, check whether the switch is normal.

3. Choose according to your needs: according to your actual needs (the spatial shape, area, and ventilation effect of the area where the ventilation fan is placed), the specific value can be determined by consulting the designer of the decoration hall and the air exchange per unit time provided by the manufacturer.

4. Look at the function: It is recommended to choose an exhaust fan product with both supply and exhaust functions as much as possible, so as to strengthen the fluidity of the air and send fresh air to the room when needed.

Note: The installation of the hidden exhaust fan should be stable, and the horizontal position of the fan should be paid attention to when installing the fan, and there should be no tilting. After the installation of the fan, the tightness around it should be checked. If there is a gap, it can be sealed with a sunlight plate or glass glue.

In modern home decoration design, the decoration design of the kitchen is a key part of the entire interior decoration, kitchen appliances and kitchen equipment are indispensable for every family, and some families are found to have some problems, such as not knowingKitchen ventilation fan1. Preliminary preparation for kitchen ventilation fans.

1. The first thing to understand is that when installing an exhaust fan in the kitchen, the position should be installed as low as possible, and the exhaust fan needs a relatively large air volume, at least larger than the air of the intake fan. Since the kitchen produces a lot of smoke for long-term use, it is best to install a washing filter when installing an exhaust fan, which will make it easier to clean and the cleaning effect will be better.

2. The exhaust fan should be installed within three feet of the cooking place, so that the oil smoke can effectively inhale the oil smoke. Finally, the exhaust fan is usually installed at a height of about one meter above the stove. After knowing the above two points, you are ready to install.

Second, the method of kitchen ventilation fan.

1. First check the exhaust fan to see if the new exhaust fan is broken or has quality problems.

2. Let's see if the installation between the various parts is firm and whether the whole is complete. This avoids defects found after installation. Rework was more cumbersome back then.

Finally, when determining where to install, you should check your surroundings. In general, do not place too many obstacles at the exit of up to 3 meters.

3. Ensure that the exhaust fan is stable during installation, and pay attention to whether the exhaust fan is in the horizontal direction of the previous mark, so that it is not easy to appear skewed, high and low, etc., and it is unsafe after subsequent use, which will also affect the use effect. At the same time, it is also necessary to pay attention to the installation and adjustment of the fan as much as possible in a convenient operating position, so that it is convenient for the owner to adjust the tightness of the ventilation fan belt in time. their own needs.

4. Finally, at the end of the installation, the exhaust fan should be checked. You can see if the seal around is good. If any gaps are found, they can be sealed with glass glue.

Then check the inside of the exhaust fan for any residue, etc. You can use the fan blades to observe manually, otherwise it is easy to damage the exhaust fan once you operate it.
