1. The automatic door of the check valve may be in the open state for a long time, and the force of the spring can no longer be automatically closed, resulting in the smell of oil smoke.

2. The flue itself has cracks. Don't wrap it in red bricks, just stick tiles. When people stay to cook, the temperature of the flue itself is different. Under the action of thermal expansion and cold contraction, the cracks in the flue itself will intensify, leading to the cracking of ceramic tiles.

solution

1, the flue needs a red brick bag.

2. Check valves and smoke pipes need to be sealed.

3. If the automatic door of the check valve fails, directly open your own range hood to blow, or directly use the electric check valve.

4. Move the check valve. Directly use the motor to open and close the automatic door of the check valve, so you don't have to worry that the oil smoke will paste the check valve for a long time.

If you don't want to buy an electric check valve, you can turn on your range hood for a minute or two without cooking at home.

Methods of reducing oil fume

1. Change the cooking habit of "stir-frying".

The oil temperature should not be overheated, and the oil temperature should not exceed 200℃ (limited to the smoke in the oil pan), which can not only alleviate the "oil fume syndrome", but also effectively preserve the vitamins of the next pot of vegetables.

2, it is best not to fry repeatedly. Repeatedly heated cooking oil, such as cooking oil used for frying food for many times, not only contains carcinogens, but also contains more carcinogens in the lampblack it produces, which is more harmful.

Be sure to ventilate the kitchen. The kitchen should always be naturally ventilated, and at the same time, a range hood with good performance and effect should be installed. When cooking, keep the range hood on, and turn it off after 10 minutes.

4. Try to use cooking methods such as steaming, boiling and frying. This can not only reduce the consumption of edible oil, but also reduce the damage to food nutrients.
