Do you live on the upper floors? There are many restaurants downstairs, how many floors do you live on? When I open the window, can I smell the smell of oil smoke?

Of course you can smell him at this time, if you open the window although he does he have a high-rise residence? There are many restaurants downstairs, how many floors do you live on? When I open the window, can I smell the smell of oil smoke?

Of course you can smell him at this time, if you open the window, although he has a range hood.

But people with low floors can eat and smell it, do you live on the upper floors? There are many restaurants downstairs, how many floors do you live on? When I open the window, can I smell the smell of oil smoke?

Of course, you can smell him at this time, if you open the window, although he has a range hood, but people on the lower floors can also eat it, and they can also smell the smell of oil smoke. The high floors can't smell the wind, do you live on the upper floors? There are many restaurants downstairs, how many floors do you live on?

When I open the window, can I smell the smell of oil smoke? Of course, you can smell him at this time, if you open the window, although he has a range hood, but people on the lower floors can also eat it, and they can also smell the strong smell of oil smoke, and they can't smell it blown away by the wind.

There are many branches downstairs in the upper floor, which should be above the tenth floor, and you can smell the smell of oil smoke when you open the window.

And we live on the upper floor, there are many restaurants downstairs, and then I live on the 10th floor, and I can smell the smell of oil smoke when I open the window, and I feel very uncomfortable.

If you live in a building, there are many restaurants under the building, and the floor you live on is not very high, so you will definitely smell the smell of oil smoke when you open the window.

I haven't lived in a high-rise, I've lived on the 4th floor, and the bottom is a restaurant, and it is true that there is always a smell of oil smoke in the house, and after you go out, others will think that you just finished cooking and came out.

When buying a house, the location of the house is very important, for example, if you have these businesses under the house, it will definitely have an impact on the residents upstairs, because their business hours are often late, and it will definitely have an impact on your rest at night, not only the impact of oil smoke, but also the impact of some noise, etc., so try to avoid this kind of house with merchants when buying a house, but if you have bought such a house, then you have no choice, you either find a way to sell the house, Change to a house away from the merchants, or you just try to open the windows as few as possible.

The disadvantage of living in a building is that the smell of food downstairs will float up, you can buy a check valve to install on the smoke port of the range hood, you will not smell the smell of others, there is no way to open the smoke smell of the window, you can only not open the window.

Do you live on a high-rise floor? If there are a lot of restaurants downstairs, can you smell the smell of oil smoke if you say hello on several floors? If you say something like this, you shouldn't smell that kind of oil smoke, and if you say it, it's through that oil smoke, and if you go through the channel of his picture, it's also chic.

For this kind of commercial self-service mixed building, it is indeed the case, there are a lot of troubles, so try not to buy such a building when buying a building, for example, the oil smoke at the bottom is rising.

The taste must be inferior to the hygienic conditions, self-service building, right?

If there is a restaurant downstairs, it will definitely smell it, but there is no way.

You can't smell it so high, and the smell of oil smoke can't be so high. And it's impossible to float vertically, and the wind is blowing away.

Do you live in a high-rise building? There are many restaurants downstairs, you live on a few floors and open the windows to smell the smell of oil fumes, telling you that now they have to be purified by oil fumes, and the system pollution cannot be opened, you can report them, or you can call 12315 to complain.

Do you live in high-rise buildings? There are a lot of restaurants downstairs, how many floors do you live on? When you open it, there are times when you do have this phenomenon, and you can smell the smoke if you get close!

Our community out of the intersection does have that high-rise building, the following is a small restaurant, the result is sometimes not very good, often some smoke will run upstairs, people can always smell the smell of oil smoke at home, all for this matter have called the police, hey, a lot of things are contradictory.

Do you live on the upper floors? How many restaurants are there downstairs? How many floors do you live on?

When I open the window, can I smell the fumes? Our family lives very low, upstairs and downstairs is the restaurant, our family smokes a day of head pain can't win, I don't know what to do? So now it is very harmful to people in the oil smoke.

The building you live in must be commercial and residential. Mixed and mixed. This kind of mixed building is not good. There are a lot of businesses that will affect the houses above.

Do you have a high floor? There are many restaurants downstairs, how many floors do you live on? When I open the window, can I smell the smell of oil smoke? This depends on the actual situation of your residence.

The first reason is that we have not installed the exhaust facilities in our kitchen in accordance with the requirements of the code. One of the most important exhaust facilities here is the check valve for exhaust smoke.

The function of the smoke exhaust check valve is to prevent the oil smoke in the smoke from returning to our room through the smoke exhaust hole. It is having a check valve.

role. If we don't install this smoke exhaust check valve, then we can say that there is a smell of oil smoke in our room.

The second reason is that the installation of smoke exhaust facilities is not standardized. The first point is that the check valve of the smoke exhaust is directly buckled on the hole and is not sealed. The second point is that the smoke exhaust pipe of the range hood is directly fixed with a nut or screw and the check valve, and there is no sealing treatment.

Because we all know that oil smoke can penetrate through gaps, and if the connected parts are not sealed, then oil smoke can also penetrate through.

The third reason is cracking in the flue. Because the flue of our house is generally wrapped in the later stage, it is almost impossible to see the leakage of oil smoke in the lower part of our ceiling. However, at the top of the ceiling, many friends may not pay much attention, so this part is particularly prone to cracking of the flue.

After cracking, the oil smoke will penetrate into our kitchen along the gaps, resulting in a serious kitchen oil smoke smell.

Because the oil smoke is quickly drifting out of the air. Your home is located just below the wind or near the smoke point.

Close the north window so that the wind does not come in.

1. Because the new building adopts the main and auxiliary common flues, when the pressure of the main air duct rises to a certain extent, the auxiliary flue connected to the range hood is in a negative pressure state, and no oil smoke backflow will occur.

2. However, if the negative pressure is too large, the valve plate of the check valve will be sucked open, and the valve plate after suction can not be effectively closed if it is adhered to the oil scale, and when the pressure of the main flue decreases, the negative pressure of the auxiliary flue disappears, and the oil smoke backs up, and there will be a smell of oil smoke downstairs when cooking upstairs.

Cooking downstairs, the smell of oil smoke upstairs may be a problem with the check valve.

Cooking downstairs, upstairs smell of oil smoke is a big reason:

In high-rise buildings, filial piety and brightness are used to concentrate on smoke exhaust in the flue, such as the problem of the check valve, which is easy to produce the situation of oil smoke cross-smell. It may also be because your building is a public flue, it should be said that it is normal, or it may be that the sealing of the window is not particularly good, and the smell from the range hood floats up, and sometimes this situation occurs in my house when it enters your kitchen, and sometimes I have no way to turn on my smoker for a while.

Precautions for check valve installation:

1. Check valve is a one-way valve that prevents water from flowing back. Therefore, before installation, it is necessary to observe the direction of the water flow, and distinguish the backstop door, and find the outlet position of the water flow to install, so that the check valve can play a better role.

2. The bearing capacity of the check valve is not strong, so you can't put heavier things on the command valve. Moreover, in the process of preventing the water from flowing back, the check valve will also bear a force caused by the water flow, so that the pressure of the check valve is greater, so it is necessary to pay attention to the protection of the check valve at ordinary times and not to damage it. <>

1. The seal of the check valve is not good.

Another reason for fume backflow is that flue fittings such as guide pipes, transformer plates, and check valves are not installed correctly, or at all. Among them, the poor sealing of the check valve is a common problem.

2. The negative pressure in the public flue is too large.

Flue, also known as exhaust duct, is a square vertical hole installed in the wall of the house, modern houses often have only one public flue, in a limited space, to focus on solving the smoke exhaust problem of dozens of households. In the process of smoke exhaust, once the smoke encounters resistance, it will slow down, the negative pressure in the flue is too large, and the smoke in the flue is difficult to be discharged, and the smoke in the flue will also be "pressed" into the kitchen of each household.

Upstairs and downstairs flue is connected, each household has a branch flue, should press a flue damper, when the flue gas is exhausted, the flue door is opened, the flue gas is discharged to the public main flue, if the flue and flue damper are not well sealed, the lower level of users once the cooking and smoke exhaust, it is easy to pour their own home, the smoke is light, it is going up. Please check the sealing condition of your flue and flue damper.

There is a check valve at the connection between the machine and the smoke pipe, some are also called the check valve, there are two semicircular plastic sheets on this valve, when the range hood smokes, the two plastic sheets are blown open by the smoke smoked by the smoke machine, and they are combined together, the range hood stops, and the two plastic sheets are restored to their original state to seal the passage between the smoke pipe and the smoke machine.

The phenomenon of smelling downstairs is generally that the check valve above has too much oil, which is blown open and closed together and sticks, and the passage between the smoke machine and the smoke pipe and the public flue is opened.

Most of the check valves on the range hood and the check valves installed in the account use the structure of the range hood to open by wind and close the valve by weight, and a small part of the valve is equipped with a spring to help the valve close. In order to ensure that the wind power of the range hood can blow open the check valve, the weight of the valve plate or the spring force should not be too large, so the closing force of the valve is small and it is easy to be adhered to oil scale. After the valve is adhered to the check valve, the opening and closing are not in place, and the consequence of not opening is that the exhaust is not smooth and the air volume is attenuated.

Reason 1: Most of the check valves on the range hood and the check valves installed in the account use the structure of the wind power opening of the range hood and the self-weight closing of the valve, and a small part of the spring is installed on the valve to help the valve close. In order to ensure that the wind power of the range hood can blow open the check valve, the weight of the valve plate or the spring force should not be too large, so the closing force of the valve is small and it is easy to be adhered to oil scale.

After the valve is adhered to the check valve, the opening and closing are not in place, and the consequence of not opening is that the exhaust is not smooth and the air volume is attenuated. The consequence of not being able to close it properly is that a large amount of oil smoke backfills will occur.

Reason 2: The check valve of most range hoods is equipped with an annular gap between the valve plate and the valve body, the purpose is to reduce the contact area between the valve plate and the valve body, reduce the adhesion force of the oil scale to the valve plate, and ensure that the wind force of the range hood can blow the valve plate. If the annular seam is too large, when the neighbor turns on the range hood (sewage discharge), the local pressure in the shared flue increases, and the sewage gas is poured from this annular seam nearby.

Reason 3: The new building adopts the main and auxiliary common flue, and when the pressure of the main air duct rises to a certain extent, the auxiliary flue connected to the range hood is in a negative pressure state, and the oil smoke backflow will not occur. However, if the negative pressure is too large, the valve plate of the check valve will be sucked open, and the valve plate after suction can not be effectively closed if it is adhered to the oil scale, and when the pressure of the main flue decreases, the negative pressure of the auxiliary flue disappears, and the oil smoke backflow occurs.

It is recommended to ask the property management company to coordinate the handling first, if there is no result, you can call the public**, and there will generally be a result. If the actual problem cannot be solved, environmental quality testing can be considered, a preliminary assessment of air and noise can be made, and a lawsuit can be filed to stop the infringement and remove the obstruction.

The state does not have a unified regulation prohibiting the opening of restaurants downstairs in residential buildings, but only requires that it must comply with the regulations on environmental protection and management of the catering service industry, and take measures to prevent and control the pollution of oil smoke to the living environment of nearby residents.

There will be some restaurants and snack bars downstairs in many communities, most of these stores are downstairs in the residential buildings, and the restaurant operation will have many right eyes, once the restaurant is not properly disposed of environmental protection will cause some trouble to the lives of the residents upstairs and around, and the restaurants in the community in many places have been complained, but in the end it is only rectification, and it will not necessarily be ordered to be demolished.

If there are regulations and regulations downstairs for residents who can't open a hotel, first complain to the 12345 Environmental Protection Bureau, the Market Supervision Bureau, and if they don't deal with it, you will directly sue the competent department to the court to revoke its business license and health permit, and you can sue the hotel You can also sue the Environmental Protection Bureau through the Market Supervision Bureau (take the administrative lawsuit, because the Air Pollution Prevention and Control Law is issued by the environmental protection department, and Article 81 has provisions prohibiting residential buildings, Commercial and residential complexes that are not equipped with special flues, as well as new, reconstructed, and expanded catering service projects that produce oily fumes, peculiar smells, and exhaust gases in commercial and residential complexes adjacent to residential floors. ）

There are also several rules and regulations that you can use.
