Description
Technical field
The present invention relates to range hood technical fields, and in particular to a kind of filter screen of range hood, range hood into
Wind system and range hood.
Background technique
Range hood is made that prominent tribute as the essential household appliances in kitchen, to build clean kitchen environment
It offers.Currently, range hood on the market largely realizes that the filtering of oil smoke is intercepted using cavernous oil network, but this scheme has
Certain drawbacks, although being exactly that most of be isolated of oil smoke filters out, but still has part smoke particle to enter air duct and be discharged
To outdoor, over time, greasy dirt particle will be adhered on motor and impeller, cause motor load to increase, revolving speed reduction, not only subtract
The suction of small kitchen ventilator influences machine life, and has aggravated outdoor environment pollution.
Occur that dynamic filtration net is arranged in the air inlet of range hood in the prior art, utilizes the rotation of dynamic filtration net
Transhipment is dynamic, and mechanical collision occurs with oil droplet, the greasy dirt particle of bulky grain, thus by detention, trapping；Under the influence of centrifugal force,
Dynamic filtration selvage is trickled down along accumulation, and greasy dirt flows downwardly into oil sump.But dynamic filtration net in the prior art and oil smoke
Contact area it is smaller, filtrable oil smoke is less.
Summary of the invention
Therefore, the technical problem to be solved in the present invention is that overcoming dynamic filtration net filtration oil smoke in the prior art less
Defect, thus provide it is a kind of can filter the filter screen with range hood of more oil smoke, the air inlet system of range hood and
Range hood.
