The function of the range hood is to discharge the oil fume generated during cooking, so as to keep the air in the kitchen fresh. However, in some special cases, such as apartments and high-rise houses, the oil fume cannot be directly discharged to the outside. At this time, some measures need to be taken to solve the problem of oil smoke not being discharged outside.

1. Use activated carbon filter. This kind of filter screen has the characteristic of adsorbing oil fume, which can greatly reduce the emission and influence of oil fume. When in use, the filter screen should be replaced regularly to ensure that the lampblack is fully filtered.

2. Install the fume purifier. The lampblack purifier is a device specially designed for treating lampblack. It can inhale oil fume, carry out deep filtration and purification, and discharge clean air. Choose products with good brand and performance when installing, and carry out regular maintenance and cleaning.

3. Use the flue exhaust fan. This kind of equipment needs to turn the smoke pipe outdoors, and then connect the smoke pipe with a small fan to discharge the oil smoke along the smoke pipe. When in use, make sure the flue is unblocked and pay attention to regular cleaning.

4. Install the fine filter system. This system can add a secondary filter on the basis of the range hood, filter and purify the oil and gas remaining in the range hood for the second time, and exhaust the purified air outside. When shopping, you should choose the model suitable for your kitchen and pay attention to regular cleaning and maintenance.

In a word, we should choose the appropriate method according to the actual situation to solve the problem that the oil fume can't be discharged. Pay attention to safety when using, and don't use oil fume to affect the human body. At the same time, clean and maintain the equipment regularly to ensure the normal operation of the equipment and reduce the impact and danger.
