After installing the range hood, what should I do if I find that there is an odor at the range hood?

Whenever it's time to cook, you can know what other people's houses are stir-frying, whether it's chili pepper or fish, through the public flue of the unit building or the range hood string to your own home, you can have a single smoke stop valve of the smoke exhaust pipe and the range hood when the range hood is installed, and there is also a pair of small blades at the junction of the hood and the smoke pipe is also a non-return, and the workers will directly remove these two when installing the hood, in order to be afraid of sticking to the after-sales problems in the later stage. Because after a long time, these two have recently begun to smell sporadically again, indicating this check valve.

It also needs to be cleaned regularly, otherwise there will be more oil smoke adsorption, which will affect the opening and closing, and also affect the effect of blocking.

<> install a check valve, buy a better one, teach you a small method, turn the check valve upside down, pour some water, if it does not leak, you can see whether the flue is installed when you start the decoration, if you press it, and then see if your ceiling is an integrated ceiling.

Yes, put the manifolds.

Unload, (when unloading with a small sticky hook suction cup) to see if the check valve is easy to use, my family is also a neighbor's cooking, my kitchen is full of the smell of oil smoke, every time I wait for the smell of smoke to dissipate before I dare to go in to cook, if he has a long time in the kitchen, it really causes a lot of inconvenience to our lives. I told you about this last time upstairs, <>

It won't get greasy after three or five years of use! So, you should know how to handle it! Buy Find a worker to disassemble the ceiling and replace the flue check valve.

Completion of this is a problem with the check valve. When you don't cook, there is a smell of oil smoke, it may be that your check valve is broken, and there is still a smell of oil smoke when cooking, it should be that someone else's range hood has a greater wind power than yours. It is a good solution to install a check valve at the flue of oil.

When you don't fry at home, the check valve is closed, and the fumes in the flue can't come in. This kind of smoke proof treasure is suitable for all kinds of smoke machines, but if the check valve that comes with the smoke machine cannot be removed, it cannot be installed.

You can install a check valve, so that these flues have no way to return to the smell, basically they will be installed now.

Check the "check damper" on the exhaust channel of your range hood at home, ask professional range hood maintenance personnel to inspect and clean the range hood, and replace the malfunctioning damper if necessary.

In this case, the ventilation duct of the range hood should be removed and installed again in the appropriate wind direction, and this problem can be solved.

At this time, it is necessary to open the window in time for ventilation, and you can also choose an efficient range hood, and do not let these fumes drift outside.

Find after-sales. In this case, ordinary people will not repair it, just call ** to find after-sales treatment.

The odor of the range hood may be that the smoke exhaust pipe and flue are not well sealed, if the smoke exhaust pipe is under the ceiling, it can be sealed with adhesive tape or sealant. If it is above the ceiling, the part that blocks the smoke pipe should be removed and glued with glass glue. It is also possible that the two sides of the exhaust hose are not tightly connected, resulting in detachment or breakage and making it smelly, so it is necessary to replace an exhaust pipe.

1. The first aspect: the smoke exhaust pipe and the public flue are not well sealed.

2. The second aspect: 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.

3. The third aspect: the exhaust hose of the range hood, the connection at both ends is not tight, falling off, and breaking will cause air leakage and odor.

4. The fourth aspect: flue problem, due to the dismantling and alteration of the flue, cracking, blockage, air leakage and smoke in the room or changing the upstairs into a pipeline, resulting in poor smoke exhaust, blocked smoke and bad smell.

The first point is that if the ceiling design of the kitchen is defective. When each family designs the kitchen, the ceiling is different because of the different types of houses, so some of them are not particularly reasonable, resulting in the tortuous and long smoke exhaust pipe, which will reduce the smoke exhaust strength of the flue.

At this time, it is necessary to redesign the length of the smoke exhaust track as much as possible.

The second point may be that the choice of range hood is unreasonable. Each range hood will be equipped with a check valve, if the smoke exhaust track is also installed with a check valve, the two levels will lead to the weakening of the smoke exhaust strength, at this time you can open the check valve on the range hood, and the smoke will be much smoother.

The third point may be that the check valve is not well sealed. After a long time, the check valve will become loose or the sealing ring will be aged, so that the smoke in the smoke exhaust pipe will be messy, and there will be a smell at home.

Fourth, it is possible that the smoke exhaust pipe is ruptured or blocked. When the room is renovated and demolished, the protection of the smoke exhaust pipe is not in place, and it may rupture or blockage, so it is necessary to find a professional to dredge and repair.

1. Check whether the inlet of the range hood hose has been changed from the front to the side of the flue, which is wrong. Because the side width of the sub flue is only 100mm, it is much narrower than the large surface. According to the principle of aerodynamics, you change the air inlet to the position of the auxiliary flue, which increases the speed of air emission rise, increases the resistance of emission, when the air convection between the kitchen and the flue, the kitchen air pressure will be less than the flue air pressure, even if the range hood does not work, the result is bound to pour smoke, and it must be changed back.

2. Check whether the check valve is installed, also known as the flue connector. Conditionally, an anti-backfill check valve can be purchased.

3. Whether the kitchen door or window is open. If the window is not opened when the range hood is working, air convection cannot be formed, and the oil smoke cannot be discharged at all; When the hood is not working, if the window is not opened, the air pressure in the kitchen will be less than the air pressure in the flue, and other fumes will pour back into the kitchen.

4. Check whether the power of the range hood has reached 500m3 h, if not, it should be replaced in time.

5. Check whether the emission of catering fumes in the building where you live (according to the design regulations, the emission of catering fumes should be discharged separately) is connected to the flue of the residential kitchen.

Why does the hood smell at home? This time I finally got it!

The floor drain in the kitchen is not anti-odor, the smoke machine has a large suction, and the smoke is taken away while opening the smoke machine, so it needs to be supplemented with new air, and the air is not easy to enter after the kitchen closes the doors and windows, and the floor drain will come out of the foul smell if it is not anti-odor.

The check valve in the public flue will not work, and the smoke of other people's houses will enter your kitchen along your check valve, unless you buy a good range hood to avoid it.

If a common flue is used, no check valve is installed or the check valve is poorly sealed, it will cause an anti-odor, that is, the so-called cross-smell.

If you're on a high-rise floor, you should install something like a smoke preventer and seal the connection between your smoke machine and the public flue.

The difficult problem of the public flue is mainly that the windproof plate of the range hood to prevent backwind is not tightly sealed, and if it is tightly sealed, it will not smell bad, but it will not be opened, so it is difficult to deal with it.

I've encountered this kind of problem a few times, so I'll tell you what the situation is, and you can refer to it.

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

Second, the single guide smoke board at the junction between the smoke machine and the smoke exhaust pipe has been for a long time, and the oil stain is sticky and difficult to open.

3. When the master installs, the interface between the smoke machine and the smoke exhaust pipe is not sealed, or the screw fixing the smoke pipe is screwed in the wrong position, resulting in the screw pipe passing through the smoke pipe cover and the single guide smoke board is on the top.

Odor from the hood is a very common problem, which can affect the freshness and comfort of the entire kitchen environment. If you are also experiencing this problem, then you don't have to worry because there are some easy ways to help you fix it.

Here are some of the possible causes of an anti-smell in your range hood, as well as the solutions you can take:

1.The filter screen of the range hood needs to be cleaned: The filter used by the range hood to filter smoke and vapors can accumulate a lot of oil and dirt over time.

These impurities can create odors, and if not cleaned in time, they can breed bacteria, which can lead to bigger problems. The solution is to remove the filters and wash them with a mild detergent to ensure they are completely dry before putting them back.

2.Exhaust ducts need to be cleaned: Exhaust ducts can also accumulate grease and dirt, especially when used for long periods of time. These blockages may cause the hood to smell off. The solution is to clean the exhaust ducts regularly to ensure that the exhaust is unobstructed.

3.Poor ventilation: The range hood needs to have a good ventilation system with the outside world to ensure the exhaust of vapors and smoke.

If the room doesn't have enough air circulation, then the hood may blow vapors and odors back indoors. The solution is to increase the ventilation of the room, open the windows or install new ventilation equipment.

4.Broken exhaust fan: The exhaust fan of the hood may malfunction, causing odors to not escape from the kitchen. The solution is to inspect the exhaust fan and repair or replace it.

5.Unsuitable cooking methods: Some cooking methods may produce more smoke and odors, such as frying at high temperatures or cooking things for long periods of time. The solution is to try to use healthier cooking methods or reduce cooking time.

In short, in order to solve the problem of the backsmell of the range hood, it is first necessary to determine the cause of the problem, and then take the corresponding solution. This problem can be avoided by cleaning the hood filter and exhaust duct regularly, and making sure the kitchen has adequate ventilation. If these methods don't solve the problem, you can consider installing a new range hood or having a professional fix the problem.

1. Check your own check valve 1, the reason why the seal of the check valve is not good for oil smoke backflow is that the flue accessories such as guide pipes, transformer plates and check valves are not installed correctly, or they are not installed at all. Among them, the check valve sealing pants are not finished is a common problem. Therefore, it is recommended that if there is a problem of oil smoke backfilling in the kitchen, first check the check valve to ensure that the check valve is installed correctly (the two fan blades are opened normally).

2. Due to the accumulation of greasy, the check valve is adhered to the check valve is opened by wind power, through the self-weight of the valve and the spring to close the work, when the range hood has been used for a long time, the valve has accumulated a certain amount of oil stain, and after the oil is adhered and the self-weight of the valve plate increases, the opening and closing are not in place, which not only leads to the backflow of oil smoke, but also causes the valve plate to be unable to open to the maximum position, resulting in a decrease in emissions and poor smoke exhaust. Second, the exhaust air pressure of the range hood, in this case, the situation of the bad smell you said will occur, in this case, you should consider changing the oil smoke with large wind pressure. You can also consider cooking in different periods, when users are concentrated in the corridor to cook, avoid peak periods, and cook after cooking.

There are several reasons for the smell of the kitchen range hood: 1. The exhaust pipe is blocked, and the smoke cannot get out, resulting in the odor. 2. The filter screen is clogged with oil, and the oil smoke cannot be sucked up, resulting in bad smell.

3. The installation direction of the check valve is wrong, and the outside air comes in and the fumes cannot get out, resulting in bad smell. 4. The wind wheel is reversed, and the oil smoke cannot be sucked up, resulting in the bad smell of the range hood.

Suggested Treatment:

Once you find that the range hood smells bad, you should first check whether there is a problem with the lower exhaust pipe. Whether the air outlet is blocked and the oil smoke can't get out, then it must be dredged. Or the interface between the exhaust pipe and the range hood is not sealed well, and there is an air leak, then reseal it again.

The filter is the part that is in direct contact with the oil, and if it is not cleaned for a long time, it will be blocked, so that the oil smoke cannot be sucked through the mesh and cause an unpleasant smell. It is recommended to remove the filter, soak it in hot water with dish soap and white vinegar for half an hour, and then brush it with a brush and put it back on.

The function of the check valve is to cause reverse flow, but if its direction is reversed, the fumes will not be able to get out. You can contact the maintenance master to reinstall it.

The existence of the wind wheel is to suck away the fumes, and if it is reversed, it will not play this role. Disassemble the hood and reinstall it in the correct direction.

The installation of a range hood in the kitchen at home is mainly to exhaust the smell of indoor oil smoke. However, how to deal with the smell of the range hood? Let's take a look at Wu Qiaoxiang.

1. If the smoke machine pipe is under the ceiling, you can consider wrapping it tightly with transparent tape, or sealing it with glass glue and 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 a part of the ceiling must be removed to glue.

2. Change the width of the check valve or clean the check valve. Usually to protect the flue check valve, the flue check valve is the safety guard in the range hood, it can effectively prevent the toxic exhaust gas and fume hood discharged from other people's homes in the public flue from pouring into their own homes.

3. Change the exhaust hose or connect the exhaust hose.
