1. The range hood is not thoroughly cleaned.
If the lampblack is not cleaned for a long time, or the cleaning is not thorough, too much grease will accumulate inside the lampblack machine, which will emit lampblack and cause the lampblack machine to smell smoke. At this time, it is necessary to thoroughly clean the range hood.
2. The exhaust pipe is blocked
If the exhaust pipe of the range hood is blocked, the lampblack can't be discharged normally, and it can only spread in the kitchen, resulting in the smell of smoke on the range hood. At this time, it is necessary to clean the exhaust pipe to ensure unimpeded.
3. The flue connection is not tight
If the flue of the range hood is not tightly connected, the lampblack will leak from the interface, resulting in the smell of smoke on the range hood. At this point, it is necessary to check whether the flue connection is firm, and if it is not firm, it needs to be reconnected.
4. The range hood is aging
If the range hood is used for a long time, the internal parts will age or fail, which will lead to the decrease of the purification effect of the range hood and make it difficult to smoke. At this point, the range hood needs to be replaced.
5. Improper selection of cooking utensils
Some cookers have a strong smell of smoke, such as frying pan and steamer. The smoke produced by these cookers is difficult to be absorbed by the range hood, and it will be distributed to the kitchen, resulting in smoke smell on the range hood. At this point, the cooker needs to be replaced.
In daily use, in order to ensure the normal operation of the range hood, it is necessary to clean it regularly, check whether the connection between the exhaust pipe and the flue is normal in time, and avoid using stoves with strong smoke smell, so that the range hood can always maintain excellent purification effect.
