Anonymous users2024-01-23When the range hood is in use, if the doors and windows are wide open, the outdoor wind blows the smoke directly, and the smoke escapes everywhere and the range hood cannot be sucked in; If the doors and windows are tightly closed and the kitchen is airtight, the kitchen will cause a vacuum, the suction power of the range hood will be smaller, and the noise will be larger. Lianbao reminds that the normal use environment of the range hood should be that the indoor airflow is relatively stable, and the oil smoke is not disturbed by the wind, and the effect is best in the inhalation machine smoothly. I asked the people who benefited from it, and said that the general practice is that the doors and windows should be opened with a crack, and it is better to blow directly into the oil smoke without wind.

Anonymous users2024-01-22It is best to open a little gap - the range hood needs to replenish the air to extract the fume, and if the door is tightly cracked, it is possible to extract dirty air from the floor drain and other places, resulting in a peculiar smell in the room. It is also possible that air may enter through the crack in the door and cause a wind whistle.

Anonymous users2024-01-21Answer yes. Because when using a range hood, if the door is opened, it will speed up the air circulation in the kitchen, resulting in oil smoke flying everywhere. In this way, the smoke absorption effect of the range hood will be greatly reduced. If the kitchen is made into a relatively closed space, the fumes generated by stir-frying will be relatively easy to absorb.
Instead of closing the door tightly, you should leave a small slit in the door so that the hood will work better. Therefore, it is best to open the door a little bit, but not all of them to avoid convection and spread the fumes in the kitchen.

When cooking and turning on the range hood, the kitchen must have doors and windows that are open to the outside so that the range hood has air to smoke, and the smoke will flow into the hood. In addition, do not turn on the air conditioner and electric fan in the kitchen, as this will reduce the smoke exhaust effect due to excessive convection. At the same time, because the kitchen uses gas, it is a dangerous place in the home, so it is necessary to open the windows to keep the air circulating. >>>More
If there is a check valve in the fume passage to prevent the fume from backfilling, there should be no need to open the window. If you didn't install a check valve when you renovated it, it was best to find a professional company to install it, otherwise there would be a greasy layer in the kitchen. Because, similar to you living in the fume tunnel of your building, it is not good for the furniture, and it is not good for the human body, because the greasy oil in the fume pipe has a lot of carcinogens!

The picture is a large stove used in rural areas, and the effect of using a ventilation fan is not good, so it is recommended to install a range hood. But it is not the kind of ordinary household, it should be installed similar to that used in the kitchen of a hotel, and the smoke hood is relatively large, which can completely cover the stove.
