Description

A kind of range hood with oil fume separator
[technical field]
The present invention relates to culinary mist extractor equipment, especially a kind of range hood with oil fume separator.
[background technology]
Because the culinary art of Chinese family is accustomed to, usual kitchen can produce very large oil smoke, therefore the lampblack filter of lampblack absorber should not adopt the structure of the filter courses such as active carbon, otherwise, the greasy dirt filtered down easily blocks mesh, space and cause die-offing of lampblack absorber air quantity, and the oil smoke suction function of lampblack absorber is gone down greatly.So the lampblack filter in lampblack absorber now, usually adopt two kinds of structures, a kind of is the structure with individual layer compared with coarse mesh or double-layer filtering net, and another kind is the filter structure with perforate.
No matter be above-mentioned the first or the lampblack filter of the lampblack absorber of the second, all leaving a very large problem, is namely the cleaning of lampblack filter and the cleaning problem of lampblack absorber.Although the cleaning frequency of the first structure above-mentioned is longer, oil smoke still easy remaining on screen pack causes the increase of windage and the reduction of fan delivery, and then affects the fume-exhausting performance of lampblack absorber.And for the second structure, although the cleaning of this lampblack filter itself obtains good solution, the spiral case of lampblack absorber inside and blower fan, still easily remain oil smoke, in the course of time, cause the gathering of oil smoke on spiral case and blower fan.If cleaning can make the running of the blower fan of lampblack absorber not as flexibly original not in time, and then affect the air quantity of lampblack absorber, and the residual of oil smoke also result in very large noise problem, the kitchen environment of user is made to suffer larger impact, and the oil smoke cleaned in lampblack absorber, be again a very hard work, cause the very inconvenient of user.These lampblack absorbers existing in addition, enter common flue through its air outlet to be then expelled in the gas of air, still containing a large amount of oil smoke, oil smoke is not only made easily to assemble in the metope of building and flue, be unfavorable for cleaning, and oil smoke drains into air, also contaminated environment, affects the healthy of people.
