What should you do if you want to completely solve the problem of oil smoke backflow?

Installing a check valve in the air outlet area of the range hood can eliminate the problems of oil smoke backflow and smoke exhaust; Or you can modify the inlet of the range hood hose and change the air inlet to the position of the auxiliary flue, which not only slows down the rising speed of the oil smoke, but also increases the resistance; Sometimes the kitchen doors and windows are closed too tightly, resulting in the kitchen air pressure is smaller than the flue air pressure.

If you want to completely solve the problem of oil fume backfilling, you need to install a check valve, and it must be sealed, otherwise it is easy to cause oil smoke backflow.

A check valve can be installed at the air outlet of the range hood, which is used to eliminate problems such as oil smoke backflow and smoke exhaust; It is also possible to modify the inlet of the range hood hose and change the air inlet to the position of the auxiliary flue, which not only slows down the rising speed of the oil smoke, but also increases the resistance; Sometimes the window is not open, and the kitchen air pressure is less than the flue air pressure, so you can open the doors and windows to try it.

Treatment method of oil smoke backfilling:

Installing a check valve in the air outlet area of the range hood can eliminate the problems of oil smoke backflow and smoke exhaust; Or you can modify the inlet of the range hood hose and change the air inlet to the position of the auxiliary flue, which not only slows down the speed of the rise of the oil smoke, but also increases the resistance.

Sometimes the kitchen doors and windows are closed too tightly, resulting in the kitchen air pressure is smaller than the flue air pressure.

If it is a high-rise building, it is very likely that in the early stage of decoration, the construction waste accidentally falls into the flue and is blocked. If this happens to many residents in the same building, contact the property as soon as possible to clean up.

The exhaust hole of the range hood is installed on the ceiling, generally speaking, the position of the flue hole reserved by the developer is facing downward, in order to install it on the ceiling, seal the flue hole originally designed by the developer, re-open an opening at the upper end, and move the flue mouth up, which will cause the auxiliary flue to lose the effect of the partition, plus the exhaust pipe is put into the public flue, which is easy to cause the situation of oil smoke backflow.

When there is a problem with the flue check valve, it will cause grease to stick to the gas, or if the counterflow valve and flue taste are not closed well, it will lead to oil smoke, it is recommended to replace a counterflow valve to try, or it can be resealed with glass glue.

Cleaning of the surface of the range hood. To clean the surface of the range hood first, dip some detergent with a rag, it is best to wipe it with warm water, which can wipe it cleaner. In addition to the surfaces to be cleaned, the walls and cooktops that are usually close to the hood should also be cleaned.

Wash the fan blades. Remove the cover and spray the detergent on the fan blades and let it sit for a while. Then boil the water, let the water vapor against the range hood, and then turn on the range hood to turn it, then the water vapor will enter the fan blades, then turn off the switch, and wipe the fan blades with a clean rag.

Wash the strainer. Next, clean the strainer by removing it and soaking it in warm water with dish soap, allowing it to soak for a while before wiping the paint off with a rag. If there are stubborn stains on the inside of the filter, you need to scrub it with a toothbrush dipped in detergent and finally wash it with water.

The solution to the public flue fume backfill is to install a tightly closed and open check valve at the air outlet of the range hood to eliminate the fume backflow and poor smoke exhaust, and the smoke exhaust mode of the main and auxiliary flue determines the smoke exhaust stall combustion by the auxiliary flue to absorb the fume.

Range hood, also known as range hood, is a kitchen appliance that purifies the kitchen environment. It is installed above the kitchen stove, which can quickly extract the waste burned by the stove and the harmful oil smoke generated during the cooking process, and discharge it outside the blind room.

Summary. Hello, I am glad to answer for you, how to completely solve the problem of public flue fume backfilling, how to completely solve the problem of public flue fume backflow is as follows: 1. You can use the check valve, which is divided into flue check valve and range hood check valve, which can solve the problem of shared flue odor, usually the builder will be equipped with a good ventilation diameter of 15cm, and the metal baffle of the eccentric shaft is inside.

The process of connecting the smoke pipe of the range hood with the smoke guard of your choice is very easy and can be done by yourself at home, but it should be noted that the joints must be plugged with dry plaster.

2. You can also buy a bottle of glass glue, the bottom layer is sealed with glass glue The effect is the best, and the use time will be longer, and glass glue is used where there are seams, so that the fume has nowhere to hide, and can only be discharged directly along the fume pipe. 3. The check valve is best installed when the bricklayer package pipeline, and a good smoke-proof treasure can be as long as the ceiling, and it does not need to be removed in the middle, which can effectively solve the problem of oil smoke in the home.

Installing a tightly closed and open check valve at the air outlet of the range hood can eliminate the backflow of oil smoke and poor smoke exhaust. Common sense tells us: the door is tightly closed, and the biggest wind can't leak in, so the reason to solve the problem of oil smoke backflow is so simple.

However, whether it is the check valve on the smoke machine or the check valve installed later is difficult to achieve "close tightly", due to structural reasons, these valves will be sucked open when the system is under negative pressure, especially the air volume of the smoke machine installed at present is getting larger and larger, the probability of negative pressure is increasing, and the frequency of oil smoke backflow is getting higher and higher.

, kitchen range hood backfilling, there is a state of Zhao may be a check valve problem. First of all, one should look to see if the range hood has a check valve. Some range hoods come with their own check valves, while others don't, and if they don't, the range hood backfill will happen frequently.

At this time, people only need to install the check valve. Secondly, people should see if the check valve is installed incorrectly, and if so, install the check valve correctly according to the instructions. Finally, see if the check valve is covered with heavy oil stains, if there is oil stains, this will affect the opening and closing of the check valve, and eventually lead to backfilling.

At this time, people can only ask professionals to clean because the position of the check valve is high.

The backfilling of the range hood may be due to the high local pressure of the hood. If the pressure of the hood is high and the pressure is low, the high pressure will suppress the low pressure, which will hinder the smoke exhaust of the range hood and eventually lead to backfilling. At this time, people should see whether the flue is transformer, if not, a check valve should be installed.

The backfill of the range hood may be too much negative pressure. Generally speaking, there will be some negative pressure in the flue, but this will not affect the smoke exhaust of the range hood. However, if the negative pressure exceeds the specified standard, the valve will be sucked open, and the range hood will be reversed.

If your range hood backfill can not be solved, and you are thinking about where to find a master to repair, then people can place an order to find a maintenance master, and more than 800,000 masters across the country are at your disposal.

Range hood backfill can be caused by the following:

1.The exhaust pipe of the range hood is blocked or bent, resulting in poor exhaust and backfilling.

2.The improper installation position of the range hood leads to insufficient distance between the air inlet and the exhaust port, and the air outlets interfere with each other and pour back air.

3.The speed of the range hood fan is too high, resulting in too strong exhaust and backfilling.

Workaround:1Clean the exhaust duct of the range hood and keep it unblocked.

2.Reinstall the smoke machine and make sure that the distance between the air inlet and the exhaust port is sufficient.

3.Adjust the fan speed of the range hood so that the exhaust is moderate.

If the above methods cannot solve the problem, it is recommended to contact professional maintenance personnel for maintenance.
