Anonymous users2024-01-23The reasons for the cross-smell are as follows:
1: The check valve of the air outlet flue with the hood is not closed tightly, or the valve is adhered by oil scale and the closure is not in place, resulting in the oil pipe odor backflow. or the bathroom smoke exhaust pipe is not equipped with a check valve, or the check valve is not closed tightly.
2: Most of the smoke machine comes with the air range hood check valve between the valve plate and the valve body has an annular seam, when the neighbor turns on the hood (drainage), the local pressure in the shared flue increases, and the sewage gas is poured from this annular seam nearby.
Three: an appropriate amount of negative pressure will be generated at the interface of the smoke machine of the common flue, and there will be no backflow of oil smoke. However, when the wind speed is too high, the negative pressure generated is too large, and the valve plate will be sucked open. Gases diffuse into the flue.
In order to solve the problem of odor transfer, a flue check valve can be installed (or replaced) at the outlet of the smoke exhaust pipe.

It's totally fine, a lot of houses are designed like this now, it's good.
I don't think there is anything between the walls, there is a wall, there is a door, and there is an exhaust, there are both sides, this kind of house design violates the design principles or what, I don't understand.
This is mainly due to the fact that the developer designed the bathroom and kitchen to be adjacent in order to save pipes.
