What should I do if the household range hood smells bad? What s going on with the kitchen hood smell

Solution: Use a flue check valve.

1. When cleaning the range hood, be sure to wear a pair of rubber gloves to clean the range hood, which is to prevent the metal parts on the range hood from scratching your hands.

2. Flue check valve: The flue check valve is a safety guard in the family, which can effectively prevent the toxic exhaust gas and oil fumes discharged from other people's homes in the public flue from backing up into the home.

Range hood anti-smell reasons:

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.

No matter what brand of range hood, the smoke exhaust and the structure (that is, the check valve) used to prevent the oil smoke from returning are the same. That is, there are two semicircular plastic plates at the top of the range hood connected with the smoke pipe, which open and close up and down with the opening and closing of the range hood.

The reason for the aftertaste is in the two semi-circular leaves. The main problem is that the blade is not closed tightly, there are gaps, when the range hood is used for a period of time, the blades will naturally stick to the oil stains, and the blades can not be restored to their original position after opening, then the gaps inside are larger, so the phenomenon of smoke and smell will be more serious.

Solution: 1. Clean up the range hood, focus on cleaning the dirt on and around the check valve, and pay attention to check whether the blade is open and closed tightly, if the blade is damaged, it should be replaced in time.

2. Install the flue check valve on the flue, and it must be ensured that the check valve is installed firmly and has no gap with the wall. Together with the check valve of the range hood, it acts as a double safety to prevent the air flow from going backwards, forcing the flue gas to move in one direction towards the flue.

The oil drain machine has a check valve, if the aftertaste may be a problem with the check valve, so check the check valve, if it is broken, change it! It is best to use an anti-odor floor drain for floor drains, and now many places on the street are sold!

There are also things to pay attention to, it is best to open the window when opening the smoke machine, if you don't open the window, it is easy to suck out the smell in the floor drain, so you need to pay attention, even if it is a window crack.

It's all a matter of experience! Good luck solving the problem as soon as possible.

1.There is no sealed solution between the smoke exhaust pipe and the public flue: if the smoke pipe 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.

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

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

4.Flue problem, due to the flue dismantling and modification, cracking, blockage, air leakage in your room or changing the upstairs into a pipeline, resulting in poor smoke exhaust, smoke obstruction, resulting in 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 reason is more difficult to solve, and it is better to find a property.

Change to a new one, I just changed a new boss 28x5s last month because of the bad smell of the range hood, which is very easy to use, the product quality of the big brand is good, the material is very good, and the texture can be seen with the eye.

To clean the range hood kitchen range hood smell, it is recommended to check whether the range hood is too thick. If the oil scale is thick, it needs to be cleaned in time, and the check valve of the smoke exhaust pipe should also be cleaned frequently to avoid.

Glass glue sealing Because the smoke exhaust pipe is not sealed well, resulting in bad smell, glass glue can be used to seal. You can also remove part of the ceiling, and then seal it with glass glue to the indoor fumes.

Install the smoke stop valve The smoke stop valve can prevent the outside wind from blowing the oil smoke back into the room, and can discharge the oil smoke in the room in time. After determining the installation direction of the smoke stop valve, use the smoke stop valve for the special purpose.

There are two situations in which the range hood is odorous, when the range hood is turned on or when the range hood is not turned on. In the case of the range hood turned on, the smell is reflected, indicating the public flue wind pressure "range hood.

Answer: The first aspect: the smoke exhaust pipe and the public flue are not well sealed; Solution: If the smoke machine tube is ,.. under the ceilingThe 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; Settle.

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 above the suspended ceiling, there are two situations.

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 flaps are active.

The exhaust hose of the range hood will cause leakage if the connection at both ends is not tight, falling off, and breaking.

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:

1. Once you find that the range hood smells bad, 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.

2. The filter screen 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 away through the mesh and the smell will appear. 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. 3. The function of the check valve is to cause counterflow, but if its direction is reversed, the oil smoke will not get out.

You can contact the maintenance master to reinstall it. 4. The existence of the wind wheel is to suck away the fumes, and if its direction is reversed, it will not play this role. Disassemble the hood and reinstall it in the correct direction.

1. The smoke exhaust pipe and the public flue are not sealed. 2. The exhaust check valve of the range hood and the two semicircular movable baffles of the check valve are opened when exhausting and closed when stopped, but because of the greasy will be more and more, the activity of the baffle is limited, resulting in the exhaust smoke cannot be discharged. 3. The exhaust hose of the range hood is not tightly connected, falls off or breaks, resulting in air leakage and odor.

Suggested treatment: If you encounter the smell of the hood, if the hood tube is under the ceiling, you can consider wrapping it tightly with transparent tape or sealing it with glass glue sealant. However, if the smoke machine pipe is on the ceiling, this will be divided into two situations, if it is an integrated ceiling, a small piece must be removed first, sealed with glass glue, if it is a gusset ceiling, then it is necessary to remove a part of the ceiling, before it can be glued.

The check valve of the range hood will not be able to effectively stop the oil smoke in the flue for a long time, and the check valve needs to be replaced. The check valve needs to be cleaned regularly to keep it clean, otherwise the check valve will be open and lose its effect. Replace the exhaust hose or connect the exhaust hose, this material can be purchased in the market.

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.

If the bathroom and kitchen are close together, when the kitchen turns on the range hood, some smoke may be discharged into the bathroom, which will cause the problem of anti-odor in the bathroom.

1. What are the reasons for the smell in the bathroom?

1. If there is an anti-smell in the bathroom, the first thing to consider is whether the sealing between the kitchen smoke exhaust pipe and the public smoke exhaust pipe is not handled well, and the kitchen smoke smell can not be discharged in time, and some of it will enter the bathroom, making the bathroom smell relatively large.

2. Another reason is that the range hood is equipped with an exhaust check valve, which has a movable baffle, which can exhaust when it is opened, and it will not be able to operate when it is closed. In the later stage, there are more and more oil scales, and the baffle is not flexible, and the oil smoke cannot be opened, and it cannot be discharged.

3. The problem may lie in the smoke exhaust pipe of the bathroom, if some hoses are selected to fall off or break, it will also lead to the smoke can not be discharged, and the bathroom will have an anti-odor.

4. Some people transform the smoke exhaust pipe without permission, but the transformation is unreasonable, such as causing the smoke exhaust to be unsmooth, which will cause bad smell.

Second, how to solve the problem of smoke backflow of range hood.

1. If the smoke exhaust pipe is not sealed well, we can use transparent tape, wrap it a few more times or use glass glue to seal, and the effect is also very good. Many smoke exhaust ducts are installed on top of integrated ceilings, and a portion of the ceiling can be removed and then sealed with glass glue. The oil smoke in the room can be discharged in time and will not drill into the bathroom.

2. In addition, the check valve of the smoke exhaust pipe should also be cleaned frequently, otherwise there will be more and more oil stains, and the smoke exhaust effect will not be good.

3. If the connection of the smoke exhaust pipe is not tight or there is a problem of breaking or falling off, it is the best policy to directly replace a new smoke exhaust pipe.

4. You can't change the smoke exhaust pipe without permission, it is easy to cause poor smoke exhaust, if you live in the community, you can find a property company and solve it by professionals. The bathroom should also pay attention to the exhaust, often open the window, if there is no window, you can install an exhaust fan, so that the indoor odor phenomenon is reduced.

Summary: When using a range hood in the kitchen, you must pay more attention to the smoke exhaust in time to prevent the problem of odor in the bathroom, and you can close the bathroom door when cooking, which can also be effectively avoided.

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.
