Why does the bathroom smell when the range hood is turned on after renovation?

Regarding the smell in the bathroom when the range hood is turned on, he is because when the range hood is turned on, the indoor air is discharged to the outside, and the indoor air pressure will be lower than the pressure of the surrounding environment of the outdoor house, and the outdoor air will enter the room through various ways, so that the indoor and outdoor pressure can be balanced. So there is still some peculiar smell in the air.

When the range hood is turned on, the indoor air is discharged to the outside, and the indoor air pressure will be lower than the pressure in the surrounding environment of the outdoor house. Outdoor air will enter the room through various ways to achieve a balance of indoor and outdoor pressure. Of course, sewer pipes and floor drains are also one of the ways, so there is gas entering the room.

Of course, there is the smell of odor.

To solve this problem, you can start from several aspects:

1.Sewer pipes (including kitchen sink drainage, bathroom drain and floor drain, bedpan sewage pipe) should have a water seal pipe (commonly known as a reverse bend) with a water seal length that meets the standard.

2.Always check the place where there is a water seal pipe, whether the water seal pipe has dried up after not going for a long time.

3.This is the simplest and most effective solution on a daily basis:

That is, when you want to turn on the range hood, first open the window of the room in the house that is far away from the kitchen (range hood). In this way, fresh air from the surrounding environment enters the room to supplement the air exhausted by the range hood. It not only solves the problem of not returning odor, but also ventilates the house by the way.

1.Check the kitchen flue outlet to see if it is blocked.

2.There is a suspended ceiling, which is not leaked from the ceiling.

3.When the hood is turned on, the kitchen window is closed, and the air is replenished from the bathroom.

4.First seal the hole in the bathroom, don't leak the air, turning on the range hood is equivalent to the suction machine of the sewer. It is recommended that the seal of the kitchen door be removed, and there must always be air.

The range hood has accumulated too much oil and needs to be cleaned up.

1. Pour the flour into warm water to make a batter, brush the batter on the oil net of the range hood with a brush, and then paste the kitchen paper on the oil net; Wait, wait, wait;

2. Then wait for 5 minutes, remove the kitchen paper, and finally wipe it with a rag.

3. Put a pot under the range hood and add water to heat, after boiling water, turn on the range hood to let the range hood absorb water vapor. For about ten minutes, the oil on the oil net will flow along the oil net to part of the oil storage box, so that it will be easier to clean it next.

4. Pour the dish soap degreaser into the basin to heat the water, remove the oil net and soak it in for about 15 minutes, and clean it with a rag brush.

5. Roll the soap block into pieces, add a little water to make a paste, and apply it to the surface of the clean oil net, and when the range hood needs to be cleaned after a period of time, as long as it is removed and wiped with a rag, the oil stain can be easily removed.

The flue and toilet exhaust ducts are shared?? When the range hood is working, the oil smoke is squeezed into the bathroom. Unless you add a check valve to the bathroom exhaust port (plastic, about a dozen pieces, the quality is very average, you need to fix it yourself).
