The newly bought range hood has oil accumulation on the air intake outlet, and it is often in the po

You're a weird question! Commonly used range hoods are windy at the top, no wind or light wind at the bottom, and the air outlet cover is only to prevent the external wind from blowing backwards. Range hood, also known as range hood, is actually an exhaust fan.

If the smoke can be pumped up, it is basically normal. Take a piece of tissue paper close to the suction port, and it is normal to be able to suck it steadily and not fall down.

Oil leakage of range hood is a very common problem, and the inspection is as follows: 1. First of all, it is necessary to check whether the exhaust pipe is unobstructed, whether the outdoor exhaust outlet is blocked, and if it is blocked, open the exhaust outlet. 2. The exhaust outlet will cause the newly installed pipeline to be unsealed, which will lead to the leakage of the newly installed pipeline under the action of continuous pressure, and there will be a trace of oil leakage if there is a small unsealed, which can be sealed with tin foil adhesive paper.

3. If the oil leakage point is around the lower part of the range hood, then you should check whether there is too much oil on the fan blades in the range hood, which will cause oil to be thrown out before and after the start and shutdown, and clean up the oil stain on the fan in time. 4. Many range hoods have an anti-return air activation plate at the exhaust outlet at the top of the machine, and after a long time, there will be a lot of oil, which will be easy to stick or semi-open, which will lead to poor exhaust and oil smoke splashing. If this is cleaned up in time, there will be no oil leakage.

The reasons are: the closing force of the check valve on the range hood is relatively small, and the valve plate is adhered to the oil stain after the range hood has been used for a long time, resulting in the opening and closing of the check valve in place, resulting in poor exhaust of the range hood, and the reduction of air volume, and the biggest impact is a large amount of oil smoke backfilling, resulting in the phenomenon of smoke from the range hood. 2. The design of the oil circuit is unreasonable, check whether the switch is soaked in oil and stained with dust, resulting in a short circuit and showing smoke from the range hood.

3. The exhaust pipe of the range hood is blocked after being used for a long time, resulting in the fact that the smoke cannot be smoothly transported out, resulting in the phenomenon of backfilling. Suggestions and treatment methods: 1. This is caused by air pressure.

When you turn on the hood, the hood is pumped out. At this time, there is negative pressure in the house. The smoke that was supposed to go out through the chimney was outward.

However, due to the negative pressure, the direction of the air flow is reversed to the house, and the smoke in the stove also runs into the house with the air flow. It means that your range hood not only sucks up the fume, but also sucks out the smoke under the stove. 2. If the windows are closed, a sealed environment will be formed, the range hood has a large suction power, and the new air enters the pot from the chimney and then brings out the firewood smoke.

In this case, it is recommended to open the kitchen window a little when using the range hood. Let the range hood have a normal circulating air pressure.

The main reasons are: 1. This situation may be that the position of the range hood is too high. 2. The suction power of the range hood may not be enough. 3. Whether the smoke exhaust pipes of the stove kang and the range hood are connected.

4. It may be caused by the good sealing of the room. 5. It may be that the wind speed is too large, resulting in insufficient combustion due to the local temperature reduction. Suggested workaround:

1. Reduce the installation position of the range hood. 2. Increase the suction power of the range hood. The use of range hood can exhaust the indoor smoke in a short period of time, but not all at once, so please keep the kitchen properly ventilated when using, the kitchen is too large will also affect the smoke removal effect, if the range hood is not cleaned for a long time, it should be cleaned in time according to the requirements of the manual.

And install the smoke exhaust pipe correctly according to the instructions, if the smoke exhaust pipe is too long and there are too many turns, it will affect the suction. Clear the obstacle in the direction of the smoke outlet. 3. It is recommended to install a check valve, which can alleviate the situation described above.

4. The working principle of household range hood is to accelerate air circulation in the final analysis, and the exhaust smoke gas is also a part of the indoor air, and the discharge of the smoke gas must also have new air to supplement the room to achieve the pressure balance between indoor and outdoor. In this way, when the range hood is working, open the window near the range hood with a small gap to alleviate this situation. 5. The wind speed of the fan can be adjusted lower.

The main reasons are: 1. The room is well sealed, and the air pressure in the room becomes low when the range hood is used, and the outside will flow from the stove pit connected with the outside world to the room, and if there is smoke in the stove pit, it will come out to the room. 2. Excessive suction power of the range hood will also cause this situation. 3. This situation will also occur when the stove pit and the smoke exhaust pipe of the range hood are connected.

Suggested treatment methods: 1. When the room is well sealed, when there is more smoke in the house, the firewood stove and outdoor firewood stove are turned on the exhaust fan barbecue stove, and the air pressure and exhaust air in the house become a larger convection, and the smoke is poured into the stove pit of the range hood in the countryside, we will see that the range hood is turned on and begins to smoke the smoke, at this time negative pressure will be formed in the room, in order to maintain the balance of air pressure, the smoke in the stove pit will be sucked into the range hood, so that you can see the smoke. The solution is to open the doors and windows properly to keep the indoor and outdoor air circulating, and this will be avoided. 2. If the suction power of the range hood is too large, it is recommended to adjust the suction gear of the range hood, and replacing it with a smaller suction power will reduce or avoid the situation of exhausting smoke into the room.

3. The stove pit and the smoke exhaust pipe of the range hood are connected, in this case, it is necessary to install a check valve in the smoke exhaust pipe of the stove pit to avoid the backflow of oil smoke.

1. What is the cause of oil leakage from the range hood?

Improper installation: When the range hood is installed, if the elevation angle is insufficient, the oil stain will not be able to enter the oil tank or oil tank smoothly, and even reverse flow, which will naturally lead to oil dripping or oil leakage. This kind of oil leakage problem will occur in the early stage of use, we can remove the range hood and reinstall it to ensure that the elevation angle is high in the front and low in the back.

The oil groove in the range hood is used to concentrate the oil smoke, if it is not cleaned for a long time, it will be blocked, or full of oil, and it will leak out if it is continued to be used. This situation will generally appear after a period of use, and the oil tank needs to be thoroughly cleaned to solve it, and the oil tank needs to be cleaned regularly in subsequent use.

Second, what problems should be paid attention to in the use of range hoods.

1. Pay attention to cleaning.

The cleaning of the range hood is very critical, before cleaning, be sure to unplug the power supply, to ensure that it can be cleaned with water when there is no electricity, if it is powered on, it is not recommended to clean the inside, you can only wipe the lower surface with a wrung out rag, otherwise the internal water seepage will lead to circuit safety problems.

At the same time, when cleaning, it is necessary to remove the internal oil tank, oil storage box, fan blades and other parts, soak them in warm water mixed with detergent, and then clean them with a rag. Avoid brushing with a hard brush, which will damage the coating on the surface and cause rust and other problems. We need to clean the smoke machine regularly, if we can't guarantee that it is clean, or if you are worried about damage to the parts, you can ask a special housekeeping service company to clean it.

What's going on with an oil leak from a range hood? Range hoods, like other household appliances, will inevitably have some "bad" problems during use, and the tricky problem of the range hood may be oil leakage: the oil does not leak into the oil cup, but leaks out from the gap or the back panel of the range hood.

What's going on? Oil leakage from range hood 1:Oil leakage from the gap or the back plate of the range hood may be due to the blockage of the oil guide hole or the oil guide pipe, after the oil smoke sucked in by the range hood is separated, the flue gas is discharged outside, and the oil is stored in the volute and the inner wall of the wind cabinet cannot flow smoothly into the oil cup; The next time the hood is turned on, the wind wheel throws the oil out of the volute and leaks it out of the gap or back panel.

Oil leakage from range hood two:The connection between the wind cabinet and the smoking cavity and the seam of the deep suction hood is not firmly connected and there are gaps, and the oil smoke is a pervasive gas, and the oil smoke enters the interlayer behind the smoking cavity, and becomes oil droplets after cooling, and the oil leaks from the gaps such as the light transmission plate and the back plate over time. Oil leakage of range hood three:

Improper installation of the smoke pipe can also cause oil leakage from the range hood. The smoke pipe installation is too long, the turning angle of the smoke pipe is too long, the smoke pipe outlet is blocked (the smoke pipe extends into the public flue too much and causes the smoke exhaust is not smooth), the public flue is not smooth, etc., can cause the smoking effect of the range hood is not good, too much oil completely flows into the oil cup, and the oil leaks from the gap or back plate.

[Causes and solutions of oil leakage from range hoods]

1. Due to the long time, the installation structure of the range hood is deformed, and the position is tilted, so that the elevation angle is insufficient and the oil leakage occurs; The range hood needs to be reinstalled; Clause.

2. The oil tank has not been cleaned for a long time, and the oil is overflowing, and oil leakage occurs; The oil box of the range hood needs to be cleaned.

3. The oil tank is misplaced, and there may be traces of oil flowing on the oil tank body; The oil cartridge of the range hood needs to be restored from misalignment; Clause.

Fourth, the sealing strip fails for a long time, add rubber or styrofoam strips to the sealing place, press the parts, and improve the sealing level; Clause.

5. The oil pipe is broken for a long time, resulting in oil leakage, and the oil pipe should be replaced.

If there is oil on the hood shell, it needs to be cleaned up in time, otherwise it will affect the normal operation of the range hood and even cause the hood to malfunction.

Here are the specific steps to clean the hood housing:

1.Start by preparing the tools you need, such as detergent, brushes, towels, etc.

2.Disconnect the power to the hood and remove the filter, soak the filter in warm water and detergent, and gently scrub it with a soft brush.

3.Use a damp towel or paper towel to wipe the grease on the surface of the shell, you can use a special detergent, or you can use alcohol, white vinegar, etc. to remove the grease.

4.For stubborn stains, you can use a special cleaner for the range hood to clean it, and use it according to the product instructions.

5.Finally, rinse with water and dry with a towel.

It should be noted that it is not recommended to use a corrosive cleaning agent such as potassium bicarbonate directly to clean the range hood, so as not to damage the stainless steel surface.

In order to avoid excessive oil stains on the range hood, you can pay attention to the following points when using it at ordinary times:

1.Keep the heat moderate when cooking and stir-frying, and avoid making too much fumes.

2.Clean the range hood in time after each cooking and frying to avoid oil residue.

3.Regularly replace the filter of the shut-off machine to ensure its normal operation.

As long as it is maintained regularly, the life of the hood will be extended and the kitchen air will be kept fresh every time you cook.
