Why does the kitchen always smell odors? Is the pipe cracked?

I always smell a smell of gas when I use a gas stove when cooking, although it is not very pungent, but I am still a little worried that something will go wrong.

I specially consulted the master, and he told me that this phenomenon is very common, and it is generally caused by two problems. One is that the gas pipeline at the bottom is loose or falling off, resulting in a gas leak, which is more terrible; The second is caused by insufficient gas combustion, which is not a big problem.

So the first thing I have to do now is to check the gas pipeline at home, because after a long time, the connecting hose of the gas stove is easy to harden, age, crack, etc., and it is easy to leak gas.

The master told me that it is best to choose a safe stainless steel bellows for kitchen gas pipes, because the stainless steel bellows are anti-aging, high temperature resistant, and it has a long service life, 50 years, which is 25 times that of ordinary rubber hoses, and the stainless steel bellows installation is also very simple, can be bent arbitrarily, and the most important thing is that the stainless steel bellows are usually connected by threaded threads, which can prevent accidental falling off.

Of course, if you still use gas hoses in your home, then you must check them regularly, and the inspection method is also very simple, we can pinch the hose by hand to see if it is still flexible, and check whether it has hardening problems. In addition, the gas hose needs to be replaced after more than two years of use.

Usually, we can also carry out a simple leak check on the gas pipe, brush the soapy water on the connection of the pipe, if there are soap bubbles constantly coming out, it means that the gas pipe at home has a leakage problem, and it should be dealt with immediately. Of course, don't panic even if there is a gas leak, open the windows for ventilation first, and remember not to turn on any electrical appliances.

If there is no leakage problem in the gas pipe at home, then it is likely to be caused by insufficient gas combustion, and insufficient gas combustion will also produce carbon monoxide emitted in the air, but this problem is relatively simple to deal with, and you can adjust the damper.

PS: How to adjust the gas stove damper? We can see that there are two movable slides on the bottom of the gas stove, and we will light the gas stove and then flip this slide until its flame turns blue.

Note that in the process of adjustment, if the flame is straight up, it means that the damper is too large, and if the flame is erratic, it means that the damper is too small, so don't get confused.

This is because your floor drain is not made of special specifications, or there is an accident with the return of sewer moisture. If you want to know if the pipe is broken, be sure to ask a professional to check it out.

It's not that the pipe is broken, it's the smell of oil smoke coming back from the main flue. Everyone shares the same flue, so there are people cooking at different times, and you can install a check valve and it will be solved.

Because the function of the range hood in the kitchen has decreased, it will fill the kitchen with the smell of oil smoke, and it only needs to be cleaned or replaced. Basically, it is not a pipe rupture.

Reason 1: The smoke exhaust pipe is not properly sealed with the common flue. 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.

Reason two: 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. At this time, it is enough to change the check valve or clean the check valve.

Reason three: The exhaust hose of the range hood is not tightly connected, falling off and breaking at both ends will cause air leakage and odor. Then we should change the exhaust hose or connect the exhaust hose.

Ways to reduce oil smoke in your home

1. Change the cooking habit of "stir-frying", do not overheat the oil temperature, and do not exceed 200 (with the smoke in the oil pan as the limit), which can not only reduce the "oil smoke syndrome", but also effectively preserve the vitamins in the pot.

2. It is best not to use the oil that is cooked repeatedly, and the cooking oil that is repeatedly heated, such as the cooking oil used to fry food many times, not only contains carcinogens itself, but also contains more carcinogens and is more harmful to the oil smoke it produces.

3. Be sure to do a good job of ventilation in the kitchen, the kitchen should always maintain natural ventilation, and at the same time, it is necessary to install a range hood with good performance and effect, and always turn on the range hood during the cooking process, and then turn off the range hood after 10 minutes of frying.

There are two reasons for this:If the public flue is blocked, this situation is not only for one family, but also for the same type of household. The range hood has a check valve that is replaced if there is a problem.

2. "High purification efficiency" - cracking method: observe the actual effect. There is no instrument, no expert, and there is no need to verify the so-called "purification efficiency" of the manufacturer, just look at the effect, as long as the visual inspection can achieve the effect you want during the peak period of the restaurant, do not care about the purification efficiency provided by the manufacturer.

Performance Overview:In order to pursue visual smoke-free, the newly developed electrostatic low-exhaust fume purifier is used to help the oil fume discharged from commercial kitchens to achieve the effect of visual smoke-free, especially suitable for restaurants without smoke exhaust shafts or without high-altitude emission conditions. All components of the Blue Pure series adopt internationally renowned brands, with perfect operation and protection functions.

The annual utilization rate of high-voltage power supply and control system is less than 1 in 1,000, ensuring excellent quality. The product has a high safety factor and is an energy-efficient choice. The patented modular assembly technology is easy to choose, and each module can handle 2000-4000 cubic hours of air.

It is the choice of kitchen fume purifier for high-end restaurants, with low maintenance costs and long service life.

There are two reasons, 1, the public flue is blocked, this situation is not only your family, and you are not the same household. 2. The range hood has a check valve, it is recommended that you check it and replace it if there is a problem. Open the connection between the flue and the smoke pipe to observe, there is also a check valve here, if there is a problem, replace it.

Check valve refers to the valve that automatically opens and closes the valve disc by relying on the flow of the medium itself to prevent the medium from backflowing, also known as check valve, check valve, reverse flow valve, and back pressure valve. The check valve is an automatic valve, and its main function is to prevent the backflow of the medium, prevent the pump and the drive motor from reversing, and the discharge of the container medium.

How it works: Check valves can also be used on lines that supply auxiliary systems where pressure may rise above the system pressure. Check valves can be mainly divided into swing-type check valves (rotating according to the center of gravity) and lifting check valves (moving along the axis).

Check valves are this type of valve that allows the flow of media in only one direction and prevents it from flowing in the opposite direction. Usually this kind of valve works automatically, and the disc opens under the action of fluid pressure flowing in one direction; When the fluid flows in the opposite direction, the fluid pressure and the self-closing disc of the disc act on the valve seat, thus cutting off the flow. Among them, check valves belong to this type of valve, which includes swing check valves and lifting check valves.

The swing check valve has a medium hinge mechanism and a door-like disc resting freely against the sloping seat surface. In order to ensure that the disc reaches the right position on the seat surface every time, the disc is designed with a hinge mechanism so that the disc has enough room to swing and that the disc is in true and full contact with the seat. The disc can be made entirely of metal, or it can be inlaid with leather, rubber, or synthetic overlay, depending on the performance requirements.

When fully open, the fluid pressure is virtually unhindered, so the pressure drop through the valve is relatively small. The disc of the lift check valve is located on the seat seal on the valve body. Except for the disc that can be raised and lowered freely, the rest of the valve is like a globe valve, the fluid pressure lifts the disc from the sealing surface of the valve seat, and the backflow of the medium causes the disc to fall back to the valve seat and cut off the flow.

Depending on the conditions of use, the disc can be an all-metal construction or in the form of a rubber pad or rubber ring inlaid on the disc holder. Like globe valves, the passage of fluid through a lift check valve is narrow, so the pressure drop through a lift check valve is greater than that of a swing check valve, and the flow rate of the swing check valve is less restricted.

This is caused by the backflow of oil fumes. It is caused by the small check valve or the check valve is not suitable. You can open the connection between the flue and the smoke pipe to observe whether the check valve is suitable, and replace it if it does not.

Hope it helps you and I wish you a happy life.

Explain that you share a flue with your neighbors.

Problems with the flue in your building, the flue in your kitchen is not sealed.

<>1. The reason for the smell of smoke in the old kitchen may be due to the aging of the smoke stop valve, which leads to the corrosion of the rubber sealing ring on the smoke stop valve, and the poor sealing property causes the smoke smell to be reversed. In addition to the poor sealing of the smoke valve, the new kitchen should check whether the public flue has a string of smoke and odor (the method of monitoring the common flue is to close the flue mouth with plastic wrap before the meal, make sure that the flue mouth is tightly closed, and then wait for the meal to finish before feeling whether the kitchen smells).

2. When you can smell the smell of oil smoke when you enter the kitchen, it means that your hood has not been deeply cleaned for at least a year, and a large amount of oil dirt will accumulate inside the hood at this time, and the smell of oil deterioration will be produced after a long time, commonly known as hala smell. If the range hood is not cleaned for a long time, it will affect the mood of cooking, and it may cause a fire. The grease in the hood will be left along the hood, this is a strong carcinogen, if it drip into our pot, how to eat the food?

At this time, you can ask a professional master to come to clean, and the smoke machine after cleaning will look new, and the mood for cooking will be very good.

3. If you exclude the reason for sealing, you can spray special air fresheners, we all know that there are all kinds of air fresheners sold in the market, so you can choose some air fresheners that can remove the smell of oil smoke or special odor removal, spray in some corners of the kitchen, of course, to avoid spraying into food or tableware, this method is relatively simple and effective. Tea residue can also be used to remove odor, and the sun-dried tea residue can be wrapped in a cloth and then placed in various positions in the kitchen, which can effectively absorb oil smoke and solve the problem of excessive kitchen oil smoke smell. The third trick, vinegar odor removal, you can prepare a bowl of vinegar in the kitchen, which can effectively remove the smell of oil smoke, of course, the vinegar is best replaced once a week to ensure the durability of the deodorant.

You can also use lemonade to remove the smell, you can slice the lemon directly, then add water to boil, and then pour the boiled water into the watering can and spray it in all corners of the kitchen, because lemonade has no chemicals, you can spray it at will, not only to remove the smell of oil smoke, but also to have the fragrance of lemon.

You can seal the bottom of the hood with transparent tape or glass glue, you can also install a check valve on the exhaust of your range hood, and you can also report this situation to the property and request the property to dismantle and install the smoke exhaust pipe.

You can install a check valve at the mouth of the kitchen flue, which can solve this problem very well. It can be glued with transparent tape under the wall cabinet of the smoke machine pipe, or it can be sealed with glass strips, and a soft exhaust pipe can be replaced, and the position of the flue opening can be changed.

You can buy a check valve and install it. It is installed at the top of the chimney. This will prevent odor leakage.

You should choose some better materials and replace the flue, so that this kind of thing will not happen, and there will be no particularly bad taste, and it will look more beautiful.

There are several possible reasons for this situation, 1. The interface between the smoke exhaust port and the flue of your range hood is not tightly sealed, and there are gaps, resulting in the exhaust smoke from the kitchen downstairs entering your home along the gaps.

2. Usually there is an anti-smoke back-up device at the smoke exhaust outlet, which is two semi-circular plastic sheets, and the semi-circular cover plate is jacked up when the smoke is exhausted. When the smoke is discharged, when the smoke is stopped, the cover plate falls back to block the external fume. You can see if the anti-backing device of your range hood is stuck, or the sludge is too sticky, and the cover plate has not fallen back.

Just wash it.

It may be because when you usually use it, the follow-up cleaning work is not done, resulting in too many oil stains in the smoker, and there will be various peculiar smells after a long time, or it is usually not ventilated often, resulting in the air in the kitchen is not very fresh, maybe the smoking effect of the smoker is not very good, resulting in every smoking is not cleaned.

Suggested Treatment:

1. Usually when we cook in the kitchen, we must open the windows of the kitchen, and it is best not to open the door, because if there is a peculiar smell, it will run into the room, resulting in a heavier taste, and after you are ready to cook, do not close the window immediately, and open it for about an hour to spread the smell inside and maintain good ventilation.

2. And usually after we use the smoking machine, we must clean its surface, as well as the stove and other places, it is best to use detergent to clean up, so that the cleaning is cleaner, and you can also spray some good-smelling, and remove the smell of oil air cleaner, which can effectively help remove the odor.

3. At the same time, you have to regularly do the work of rolling and cleaning the inside of the suction machine, when carrying the lead, this needs to be disassembled, if you don't, then you can find a cleaner to help you, only do a good job of maintenance, so as to improve its service life.
