Can t smoke out of the catering kitchen, why?

Kitchen fumes have always bothered many people, polluting the air and staining the walls of the kitchen. Although many families are now equipped with range hoods and other smoke exhaust equipment, they have not been able to perfectly solve the problem of kitchen fumes. It's not that the range hood is useless, but it's not installed properly, which makes the range hood unable to play its maximum effectiveness.

So, how to solve the problem that kitchen fumes can't be discharged? What are the solutions to the kitchen fumes that can't be discharged?

Kitchen fume can not be discharged treatment skills 1: the auxiliary flue must be retained.

Every kitchen has a flue, but did you know that there are also main and secondary flues? The main flue runs through the entire building. The secondary flue is relatively independent, it is separated from the main flue by a perforated partition, and the upper and lower flues are sealed by the floor slab.

Generally, the oil smoke at home will first go to the auxiliary flue to make a buffer, and then enter the main flue through the hole in the partition, so as to ensure that the oil smoke of each household is isolated and will not string smoke.

The main and auxiliary flues must be present at the same time. The phenomenon of smoke backing or smoke stringing in some homeowners is likely due to the wrong connection of the smoke exhaust pipe to the main flue during the renovation, or the removal of the auxiliary flue to save space. If it is directly connected to the main flue, it can be compared to the "cupping effect" because of its large upward suction, once the air pressure is relatively low, it may press the oil smoke of other houses to your own home.

The auxiliary flue has a good buffering effect, so it cannot be removed.

Kitchen fume can not be discharged processing skills two: pay attention to the construction details.

First of all, it is very important to choose the location where the range hood is installed. Be sure to make the pipe as short as possible. Some owners will stretch the pipe longer for the sake of aesthetics, so that after turning off the range hood, a lot of oil smoke will accumulate in the pipe and cannot be discharged, and then poured back indoors.

In addition, in order not to destroy the original main and auxiliary flues, the opening direction can not be changed at will, and must be played in the auxiliary flue. The owners can't change it to their liking. However, the hole of the flue can be enlarged, but be careful not to break the baffle of the auxiliary flue.

The smoke is too large or the range hood is not very functional.

Catering kitchens need high-power range hoods, because catering stoves are relatively large, so high-power range hoods are needed.

The range hood needs to be cleaned regularly to achieve the desired effect, so if you want the range hood to have an effect, you have to clean it regularly.

If you exclude those factors, it is simply that the kitchen smoke is too thick, so it will not be able to smoke it for a while.

8 meters of pipe, you use an axial fan, there is definitely no way to smoke! The diameter of the pipe is also too small, it should be around 300! Rectify the pipes and replace them with centrifuges.

Check if it's plugged in and if it's broken.

It may be blocked, or it may be that it can't be pumped, find a time to check it or call someone to repair it!

You can discharge this is strange I really don't know who designed it First of all, the pipe 200 is a bit small, and the ground discharge pressure is large, the axial fan is definitely not good, the pressure is not enough, the centrifugal fan can barely be discharged, and the centrifugal fan is installed, but your pipeline is unreasonable, the centrifugal fan pressure will be poured back from the axial fan, so the effect of plugging the axial fan ** should be much better Solution: Replace the tee with an elbow, only link the centrifugal fan and the main air duct, and the axial fan is not used.

The range hood may be broken or blocked, find a master to overhaul it!

There are many reasons: 1. Due to the serious oil pollution of the range hood, the motor bearing is blocked by the oil, so that the smoke cannot be smoked. 2. The thermal protector or fuse of the motor is burned out, which causes the motor to stop working and cannot smoke.

3. The motor stops running due to damage to the internal parts of the motor and cannot smoke. Suggested treatment: 1. Because the bearing of the range hood is an oil-impregnated bearing, the oil emitted by cooking will enter the small hole of the oil-impregnated bearing, and the lubricating oil circuit will be cut off.

It is recommended to check the severity of the oil stain, if you can clean it yourself, you can clean the oil directly, if the dirt is serious, it is recommended to ask a professional cleaning master to disassemble and clean. 2. First of all, we need to judge whether the internal parts are burned or damaged, if the thermal protector or fuse has been burned, the thermal protector or fuse should be replaced. Poor contact between power plug and socket, this problem is relatively simple, you can check the power indicator, whether it is still stable and on, if it will be off, and then it will be bright, it means that the circuit has a problem of poor contact.

If this is the case, it is recommended to replace the thermal protector or fuse. 3. If you try it or find that it can't be solved, it is very likely that the motor parts are damaged, it is recommended to check each part of the motor in turn, especially to observe whether there are scorch marks at the motor parts. If there are no obvious traces and the cause cannot be identified, it is recommended to replace the motor directly.

Summary. Hello The reason why the kitchen fume can't be discharged 1 may be the ventilation area of the main smoke exhaust pipe, which leads to the increase of the positive force of the section, and the flue will naturally have a poor smoke exhaust. 2. It is possible that the oil-water mixture in the pipeline accumulates in the smoke exhaust pipe, which will affect the smooth smoke exhaust.

3. It is also possible that the smoke on different floors is discharged along the same main pipe, usually speaking, the smoke exhaust effect of the flue near the outlet is better, and the smoke exhaust of the smoke pipe on the lower floor is not very smooth.

Hello Kitchen oil or smoke can not be discharged 1, it may be the ventilation area of the main smoke exhaust pipe, resulting in the increase of the cross-section yang force, and the flue will naturally have a poor smoke exhaust. 2. It is possible that the oil-water mixture in the pipeline accumulates in the smoke exhaust pipe, which will affect the smooth smoke exhaust. 3. It is also possible that the smoke jackets and socks on different floors are discharged along the same main pipe, generally speaking, the smoke exhaust effect of the flue near the exit is better, and the smoke exhaust of the smoke pipe on the lower floor is not very smooth.

How to fix it. It is recommended that you change to a range hood with automatic pressurization function, which can be discharged when the flue exhaust is not smooth or the smoke pipe is blocked.

Summary. The reasons why the range hood cannot smoke are as follows: 1. The partition in the middle of the exhaust pipe is not straightened or opened, or the exhaust pipe is artificially blocked; 2. The wind wheel is reversed or damaged; 3. The smoke exhaust pipe is blocked; 4. If the capacitor is damaged, the two-phase electricity needs a capacitor to rotate forward, and the three-phase electricity does not need a capacitor, which causes the motor of the range hood to reverse, and the oil droplets will not be seen in the oil drop box; 5. The motor is damaged, the power becomes smaller, or the exhaust pipe is too long, and the resistance increases too much.

It may be that the power socket is not plugged in properly, causing the line connector to be desoldered. It is also possible that the capacitor has been lost, the capacitor capacity of the motor starter has been reduced or the open circuit has been short-circuited, causing the range hood to not be able to extract fumes. 1. Check whether the power socket at home is installed in place, if the contact between the plug and the socket is poor or the power switch cannot be started, then the range hood will definitely not be able to pump out the fume.

2. When cleaning, the range hood must be disassembled and cleaned, sometimes the line will be touched and the line joint will be dewelded, and the circuit break point and desoldering head should be checked. If the circuit break and desoldering head are damaged, they need to be replaced. 3. If water enters the range hood, it may cause damage to the capacitor of the range hood and reduce the capacity of the starting capacitor or open circuit and short circuit.

In this case, the capacitor motor can only be restarted if it is possible to replace it with the same model. 4. Do not stain some parts of the range hood with water, which will cause damage to the contact key of the motor switch, resulting in the range hood not being able to work normally and not being able to extract the fume. 5. When cleaning the range hood, you must wait for the water to dry completely before you can plug in the range hood and use the range hood, otherwise it will lead to the risk of electric shock of the range hood.

Therefore, be sure to wait for the moisture on the hood to completely dry before starting the hood.

Since the kitchen is often stir-fried and cooked, the smoke is relatively large, and the range hood needs to be installed. So what if there is no range hood in the kitchen? PChouse will take you to find out.

1. First of all, the range hood is not installed, and there are ways to use stir-fry when cooking, and the closed kitchen space is full of oil smoke, the oil smoke is more serious, and people who stay in this environment for a long time are easily damaged, so if you want to quickly remove such a taste, you can open the doors and windows to ventilate and disperse the smell when cooking, so that it is also very effective to reduce the oil smoke by hand combustion.

2. If the location of the kitchen is not suitable for opening doors and windows, it is necessary to use external force to eliminate the residue fume, the most convenient of which is the air freshener for the kitchen to remove the odor and fume, which can not only quickly suppress the odor, so that the whole room is full of fragrant taste, and it can be used in the kitchen, and has a certain effect.

3. If there are family members who like to drink tea, collect the soaked waste tea residue and then dry it in the sun, so that Bi Chong wraps it in small gauze and divides it into packs and puts it in all corners of the room, using the physical adsorption principle of tea to remove the smell of oil smoke, which is also a very convenient and money-saving method.
