Causes of odor in kitchen flue
First of all, the ceiling design is flawed:
Because of the design of kitchen ceiling, the smoke exhaust pipe is too long, which reduces the smoke exhaust intensity of range hood.
Second, the purchase of range hoods is unreasonable:
The range hood itself has a check valve, and with the check valve installed in the flue, the lampblack has to go through two checkpoints to enter the flue, which leads to the weakening of smoke exhaust.
Third, the check valve is not tightly sealed:
Improper installation of the check valve or aging of the sealing ring leads to smoke in the pipeline entering the room; The check valve meniscus does not close tightly.
Check valves must be installed strictly. When bricklayers stick bricks, they must find out the size of the flue outlet and install it properly. If the willow leaves at the exhaust port are too large, there will be smoke leakage.
Four, pipeline rupture or blockage:
During the reconstruction and demolition, the protection of the exhaust pipe was not in place, and the pipe wall was broken, which led to the smell of smoke.
For the odor problem of kitchen flue, it is necessary to prescribe the right medicine and completely solve the odor problem of kitchen flue! Next, let me tell you the solution. For new houses, the position of flue is often wrong. Considering that the kitchen will affect the height of the ceiling, many vents need to be adjusted.
1. The smoke exhaust pipe is not well sealed with the public flue.
2. Exhaust check valve of range hood. The two semicircular movable baffles of the check valve open when exhausting and close when stopping. However, due to the accumulation of grease, the movement of the baffle is limited, or even it can't be opened, and the oil smoke can't be discharged.
Solution: the check valve that comes with the new house is relatively difficult to use when it is delivered. Check valves are relatively cheap, so it is more troublesome to buy new ones to avoid problems in the later stage.
3. The exhaust hose of the range hood is not tightly connected at both ends, and it will fall off and break, which will cause air leakage and odor.
Solution: this problem will not occur when decorating a new house. You must choose a good quality hose for the smoke exhaust pipe. If the smoke hose is of poor quality for a long time, it will fall off and break, so there will be signs of odor in the kitchen.
4. Flue problem: The flue in your room is dismantled, cracked, blocked, leaked and smoked, or the upstairs is changed into a pipeline, which leads to poor smoke exhaust, blocked smoke and bad smell. Similarly, if there is a problem with the exhaust pipe in the bathroom, it is also the reason.
Solution: This situation is very complicated and difficult to solve. If there is such a reason at home, you should find a property manager or a worker's master to solve it in time, because neighbors may go upstairs and downstairs without knowing the purpose of the flue, and the consequences will be very serious, affecting the smoke exhaust on the first floor. Pay attention at work.
