How to design a kitchen to completely avoid these problems?

Nowadays, people pay more attention to air pollution. They are used to checking the PM2.5 index, but they often ignore the indoor air pollution. In family life, when we use cooking oil to produce oil fume, it contains many toxic and harmful organic compounds, which will irritate people's eyes and respiratory tract, thus inducing diseases.

Mr. Cai, the owner of Yulin, has lived in this old house for nearly ten years and cooks for his family every working day. Whenever he stands in the kitchen, he can smell the rice from his neighbor's house. Over time, he can know what his neighbors are eating today by the smell of lampblack. He not only has to endure the test of neighbor's lampblack, but also endures the situation that neighbor's lampblack spills into his kitchen! Every time I cook, the kitchen is mixed with the lampblack of my own house and the lampblack of my neighbor's house. After a meal, you will be smoked and greasy, and you will have no appetite to eat. ...

Although Mr. Cai's wife seldom cooks, she often feels that smoke wafts into the living room after the kitchen is backfilled. Especially when cooking some spicy food, the strong smell of smoke is even more unbearable. When she is seriously ill, she will keep coughing. At first, Mr. Cai's family did not have such a serious situation of soot reinjection. Just like ordinary people, you can smell some food when you eat. With the passage of life, the situation of kitchen fume reinjection is becoming more and more serious.

I believe many owners have the same situation as Mr. Cai's kitchen. The early performance of oil fume recharge is just like what Teacher Cai said, "Smell the vegetables." If the problem is not solved, the longer it drags on, the less optimistic the situation in the kitchen will be and the health of family members will be affected for a long time. Today Xiaoqi will talk about kitchen lampblack reinjection. At present, most houses have public flues, which discharge centrally from the roof. Whenever the cooking peak, the resistance of public flue increases sharply, which leads to a large number of lampblack being blocked together, resulting in lampblack reinjection.

Many owners don't know this, and they don't pay attention to installing smoke prevention valves, or they don't install them right at all! At this time, as long as a family turns on the range hood, or the wind is discharged from the roof into the flue, the fume in the flue will enter the range hood with a pungent smell through the gap of the smoke exhaust stop valve, causing the fume to be reinjected. Another well-known reason is that your range hood is not selected correctly.
