Is there any good way to solve the smell of the common flue in the kitchen?

Kitchen flue odor is one of the most common phenomena in life, but this is a kind of trouble, so what to do about kitchen flue odor? Today, Nanjing Decoration Network will tell you about the reasons for the smell of the kitchen flue and the way to deal with it.

The cause of the unpleasant smell of the kitchen flue.

1. Defective ceiling design:

Due to the design of the kitchen ceiling, the smoke exhaust pipe is too long, which reduces the smoke exhaust strength of the range hood.

Second, the purchase of range hood is unreasonable:

The range hood itself is equipped with a check valve, and with the check valve installed in the flue, the oil smoke has to go through two checkpoints before entering the flue, resulting in a weakened smoke exhaust force.

3. The check valve is not tightly sealed

The installation of the check valve is not tight or the sealing ring is aging, causing the flue gas in the pipeline to string into the room; The meniscus closure of the check valve is not tight.

The installation of the check valve must be tight, and the bricklayer must find the size of the exhaust outlet of the flue when tiling, and install it if the exhaust outlet willow is too large, there will be a problem of smoke leakage.

4. Pipeline rupture or blockage:

In the decoration and demolition, the exhaust pipe is not protected in place and the pipe wall is broken, resulting in smoke and smell.

For the problem of kitchen flue odor, we must prescribe the right medicine and completely solve the problem of kitchen flue odor! Next, let me tell you about the solution. For new houses, many times the position of the flue is not right, considering that the kitchen does the ceiling, the flue exhaust outlet will affect the height of the ceiling, so many exhaust outlets need to be adjusted.

1. The smoke exhaust pipe and the public flue are not sealed.

2. The exhaust check valve of the range hood and the two semi-circular movable baffles of the check valve are opened when exhausting and closed when stopped, but due to the accumulation of greasy, the activity of the baffle is limited, or even not opened, and the fume cannot be discharged.

Solution: When the new house is delivered, the check valve is relatively not very easy to use, and the check valve is relatively cheap You can buy a new one to avoid problems in the later stage, and then it will be more troublesome.

3. The exhaust hose of the range hood is not tightly connected, falling off and breaking at both ends, which will cause air leakage and odor.

Solution: This problem will not occur in the general decoration of new houses, the smoke exhaust pipe must be selected first-class hose, if the quality of the smoke exhaust hose is not good for a long time, it will fall off and break so the kitchen will have signs of bad smell.

4. Flue problem, due to the flue demolition and modification, cracking, blockage, air leakage in your room or changing the upstairs into a pipeline, resulting in poor smoke exhaust, blocked smoke, and bad smell. In the same way, if there is a problem with the exhaust duct in the bathroom, this is also the reason.

Solution: This situation is more complicated and difficult to solve, if there is such a reason at home, it is necessary to find the property or the worker master to solve it in time, because it is possible that the neighbors who go up and down the stairs do not understand the use of the flue and demolish it privately, the consequences will be very serious, and it will affect the smoke exhaust of a floor. Everyone should also pay attention to it when constructing.

Another closed valve can be installed at the flue mouth, which can ensure that the oil smoke of each household is isolated. There is also a regular cleaning of the waste oil in the oil storage box of the range hood.

If the smoke machine tube is under the ceiling, you can consider wrapping it tightly with transparent tape, or sealing it with glass glue or sealant. If the smoke machine pipe is on the ceiling, there are two situations, if it is an integrated ceiling, remove a small piece, and then seal it with glass glue, if it is a gusset ceiling, then you must remove a part of the ceiling before you can glue.

The outlet is equipped with a grid and an iron bracket with a baffle, and the smoke is dissipated around the baffle, and the smell is blown in by the natural wind of the outlet chimney. As long as you cut a round piece with a steel mesh and put it into the barrel mouth, it solves some of the problem of taste reversal.

You can choose to install a closed valve at the flue mouth at home, so that under the joint action of the smoke valve and the closed valve, you can prevent the backflow of oil smoke. However, it should be noted that the installation of a closed valve can only be used when the backfilling is not particularly severe. This is because the smoke at home will first pass through the auxiliary flue, and then enter the main flue through the hole in the grid, this design is to ensure that the smoke of each household can be isolated, if the home will be directly connected to the auxiliary flue in the main flue, it may be due to the low pressure and lead to string smoke or smoke and other phenomena.

If the phenomenon of oil smoke backflow is more serious, then it is best to install a check valve with better crack quality at home, a good command valve, the working principle is that the flue gas does not flow down after passing through the command valve, but flows straight up. Under normal circumstances, the effect of the check valve of the range hood is not particularly obvious, and the installation of the check valve in the flue can protect the range hood, so that the smoke in the flue will not be poured into the pipe and the range hood.

It is recommended that when you buy a range hood, you must try to choose a big brand, so that the after-sales service is guaranteed, and the decoration workers must also be experienced in potato sources, so that you can live comfortably after moving in, and reduce some unnecessary maintenance in the future. Once you find that the range hood at home has the phenomenon of oil smoke backfilling, you should invite someone to come to the house to check in time.

<><How to deal with the smell of kitchen flue, who has no good solution?

1: Because the smoke machine comes with a check valve and the closed valve installed at the flue mouth adopts the structure of relying on the wind power of the smoke machine to open, the self-weight of the valve plate or the installation of a closing spring. In order to ensure that the wind power of the smoke machine can blow open the valve, its weight or spring force can not be too large, so the closing force of the Xuxiangpei valve is small, and the valve is not in place after being adhered to the oil scale, and the consequence of not opening in place is that the exhaust is not smooth and the air volume is attenuated; The consequence of not being in place is that a large amount of oil smoke backfill occurs, which is a common phenomenon of oil smoke backflow.

Two: the smoke machine comes with a check valve in the valve plate and the valve body between the valve plate and leave an annular seam, when the neighbor opens the smoke machine (sewage), the local pressure in the common flue increases, the sewage gas is poured from this ring seam nearby, and the old flue is poured back for this reason.

Three: When the appropriate wind speed passes through the common flue, an appropriate amount of negative pressure will be generated at the interface of the smoke machine, and no oil smoke backflow will occur. However, when the wind speed is too large, the negative pressure generated will be too large to suck open the valve, and the valve after sucking open cannot be effectively closed if it is adhered by oil scale, and the oil smoke backflow occurs when the negative pressure disappears.

Because the flue design specification is determined by 10 cubic meters, and now the air volume of the flue is mostly more than this value or even 17 cubic meters, and the phenomenon of oil smoke backflow caused by high air volume is gradually increasing.

Four: when the smoke exhaust pressure and air volume of the upstairs hood are large, it will produce wind resistance in the flue, block the rise of oil smoke downstairs, and make the local pressure increase difference in the downstairs flue, and the dirty gas in the flue leaks from the check valve with poor sealing effect after the local pressure increases, which is the reason for the upstairs cooking and downstairs backfilling.

The above matters related to the anti-odor of the kitchen flue are introduced here, the oil smoke backfill always occurs when the hood is not used, and the air volume of the large and small air volume hood is zero in the shutdown state, so the air volume of the hood is not related to the oil smoke backfill.

1. Cause of failure: the smoke exhaust pipe and the public flue are not well sealed;

Solution: If the pipe of the hood is under the ceiling, it can be wrapped tightly with transparent tape, or sealed with glass glue and sealant.

2. Cause of failure: the exhaust check valve of the range hood, the two semi-circular movable baffles of the check valve, open when exhausting, and close when stopping, but due to the accumulation of greasy, the activity of the baffle is limited, or even not opened, and the fume cannot be discharged;

Solution: Change the check valve or clean the check valve.

3. Cause of failure: The exhaust hose of the range hood is not tightly connected, falling off and breaking, which will cause air leakage and odor;

Solution: Change the exhaust hose or connect the exhaust hose.

For the kitchen, its biggest problem is the heavy smell of smoke, so when the layout, most of the owners will focus on the smoke exhaust, and the kitchen flue is currently installed in the kitchen of the residential building, its main role is to help people to eliminate the smell of oil smoke generated when cooking in the kitchen, to avoid leaving in the kitchen and produce spring dirt and smell, affecting people's normal use, so what to do with the kitchen flue smell? Let's take a look.

If the smoke exhaust pipe is not properly sealed, it is recommended to wrap it tightly with transparent tape. Due to the accumulation of greasy oil and the limited movement of the stopper, it is recommended to change the check valve or clean the check valve. If the two ends of the exhaust hose are not tightly connected, fall off and break the air leakage and smell, it is recommended to change the exhaust hose.

If there is a problem with the flue, it is recommended that it is best to find a property to solve it.

What are the precautions for kitchen flue installation.

1. Generally speaking, there will be the main and auxiliary in the installed flue, the main flue is connected to the whole floor, and the auxiliary flue is an independent individual, when the smoke is exhausted, the oil smoke is the first to enter the secondary flue, and then enter the main flue, so that the phenomenon of string smoke will not occur, if the main and auxiliary are connected together, there will be a string of smoke Hu trembling.

2. In the later stage, when cleaning the flue, in order to prevent the joints from cracking, it is recommended to hang the net on the wall and then clean it. In addition, pay attention to the length of the pipe during installation, many friends deliberately leave the pipe longer for the sake of beauty, in fact, the flue should be as short as possible.

3. The function of the flue is mainly to eliminate oil smoke, so some friends will directly punch holes in their own walls in order to avoid the phenomenon of string smoke, which is not allowed; It is recommended to pay attention to the opening direction of the flue before installation, and do not change its direction easily and arbitrarily; In addition, when installing, the hole should be communicated with the property in advance, and the construction must be started after the consent of the property, so as to avoid some unnecessary troubles.

Summary: Okay, the above is about the kitchen flue smell of the content of the introduction, I hope to provide you with some help, I believe that in the future in the kitchen flue smell of the understanding process, friends will be more handy, get their own satisfactory answers.

The kitchen is the most frequent place to use in our daily life, if the decoration is not done well, you will encounter some troubles when cooking, when it comes to meal time, the smell of some stir-fried food is not their own, but the smell of the neighbor's fumes! What is it that makes the kitchen smelly? 

One thing that every kitchen we have is the flue pipe, and you should not underestimate this thing. If the decoration is not done well, it will make the neighbor's fumes run everywhere! Everyone must pay enough attention to it. 

First of all, we should do an inspection of this flue before we decorate, and check whether it is damaged. In addition, it is necessary to check the ventilation of this flue, you can take a cigarette and put it at the mouth of the flue, and light it to see if it can be sucked in smoothly. 

In addition, when laying tiles, it is also necessary to pay extra attention to the flue pipe, the water absorption rate of the flue tube itself is not like our ordinary cement wall, the flue is particularly easy to crack the hollow drum, and it will also cause the situation of oil smoke backfilling, some house developers in order to save costs, the flue is to use some mineral wool board and cement board, the surface is particularly thin, the thin surface does not absorb water, and the heat permeability is high, so that the tile is pasted on, and the thermal expansion and contraction for a long time means that the tile is easy to fall off when it is glued. 

Therefore, you can choose to wrap a layer of bricks to reinforce, which will be stronger and not hollow. Of course, this red brick will take up some space! Also, when pasting tiles, you can brush the glue or directly use tile glue instead of cement. This ensures that it does not fall off or crack! 

In addition to the construction to pay attention to these matters, there is also a small device that also needs special attention, that is, the flue check valve, some people forget to install when decorating, and it is more troublesome to install it later. So be sure to remember to install this thing when decorating. In addition to stopping oil fumes, check valves can also prevent mosquitoes, cockroaches, geckos, etc. from entering our homes through the flue.

However, if you choose some inferior ones, it will cause oil smoke to backfill, which will not work at all. 

The flue check valve is available in plastic and stainless steel. Both plastic and stainless steel have their own advantages and disadvantages, the plastic baffle is flexible, the smoke exhaust effect is good, and the stainless steel is resistant to high temperatures. How you choose is up to your own needs. But don't buy the cheap ones, the ones don't work at all! 

The above are some precautions for the kitchen decoration flue from construction to installation, I hope it can help all owners and friends. So that when you cook, you don't have to worry about the fumes backing up!

1. A return valve must be installed at the exit of the public flue in the kitchen at home.

2. There should also be a return valve on the range hood.

3. A tightly closed and open-place check valve can be installed at the air outlet of the range hood to eliminate the backfilling of oil smoke and poor smoke exhaust.

The answer can be added to the closed valve at the flue mouth, under the joint action of the smoke valve and this valve, the insignificant oil smoke backfill can be solved, usually the oil smoke will go to the auxiliary flue at home, and then use the hole on the partition to enter the main flue, so as to isolate the effect of oil smoke, if the auxiliary flue is connected to the main flue, it will be because the pressure is too low, and the symptoms of backflow appear. You can add a high-quality check valve, because after the oil smoke passes through the check valve, it will not flow downward, but will flow upward, usually the effect of the range hood check valve is not significant, and the installation of a check valve on the flue can play a role in maintaining the effect of the range hood, avoiding the oil smoke from backing up into the pipeline and the machine.

How to solve the problem that the smell of oil smoke in the kitchen is too important 1. You can boil vinegar in the kitchen, wait for it to boil and then let it volatilize slowly, so as to remove the smell of oil smoke, you can also buy a freshener or put a few lemons in the kitchen. 2. When cooking food, you can turn on the range hood and then open the doors and windows for ventilation to ensure smooth air circulation.
