The range hood is a kind of equipment in restaurants and restaurants, which can reduce kitchen fume, keep the kitchen clean and reduce greasy smell. However, sometimes the range hood does not absorb oil, which is a common problem. Here are some possible reasons for this.

1. Too much oil. Oil cooler exists in inconspicuous parts, such as air filters and oil fume pipes, etc. If it is not cleaned in time, it will cause blockage and the range hood will not absorb oil.

2. The oil fume pipeline is not laid correctly. The laying of oil fume pipeline must be fixed and the installation interface should be tight, otherwise it will affect the smoke extraction effect.

3. The oil fume pipe is too well insulated. The oil fume pipeline is too isolated, which may cause the oil fume to be isolated in the pipeline and cannot be pumped away by the range hood.

4. The exhaust capacity of the range hood is insufficient. If the exhaust capacity of the range hood is insufficient, it will not be able to effectively extract the lampblack.

5. The fan is damaged. This problem rarely occurs, but if the fan is damaged or fails, the range hood will not work normally.

Conclusion

In order to make the cooking range hood work normally, it must be maintained regularly in time and be used correctly during use. If the range hood does not absorb oil, you can first check whether there is too much oil, whether the exhaust is good and whether the fan is normal. If all these are normal, consider checking and cleaning the oil fume pipes and air filters at regular intervals to ensure that the range hood can work normally.
