Description
Technical field
The present invention relates to range hood, particularly the fume purifier of fume of range hood.
Technical background
Existing range hood, general all be provided with fume purifier of fume at the air inlet position of range hood air cabinet or at the air inlet front end of blower fan, fume purifier of fume is many by wire mesh structure part, metal perforated plate structural member, consist of with the metal filter-plate structure spare of flanging bore etc., also has to be made of nonmetal filter structure.It is plane that fume purifier of fume generally all is, or be arc surfaced, or cup-shaped.
The size of fresh air inlet and compactness extent not only have important effect to filtration, condensation, separation, collection, the purification of oil smoke, and the air quantity of range hood is also had important impact.
Usually, the fresh air inlet of fume purifier of fume is little and fine and close, and is relatively better to filtration, condensation, the separating effect of oil smoke, but the wind loss of range hood is relatively large; Fresh air inlet is large, and is relatively relatively poor to filtration, condensation, the separating effect of oil smoke, but the wind loss less of range hood.
For the fume purifier of fume that adopts woven wire or nonmetal filter structure spare, in the use, mesh is easy to be stopped up by grease, needs frequent clean metal silk screen or changes filter screen, otherwise not only can significantly reduce the catharsis of oil smoke, and the exhausting effect of range hood can the remarkable variation.
Adopt the fume purifier of fume of large ventilation hole structure, although the hole is not easy to be blocked, the fume purifying effect is not as good as woven wire and nonmetal filter screen.
For the blower fan of range hood, guarantee that the exhausting effect of blower fan is unaffected, the air vent area of fume purifier of fume at least can not be less than the air-admitting surface of blower fan.
Existing range hood owing to being subjected to the restriction of the air inlet sectional dimension of range hood air cabinet, adds the consideration in the appearance design,, the air vent area of fume purifier of fume is generally less than normal.
To fume purifier of fume, how in the situation that raising fume purifying rate makes the wind loss of range hood be reduced to minimum degree again, this is the problem that present range hood develops required further solution.
Summary of the invention
The present invention puts forward for above-mentioned deficiency just, its purpose is exactly by adopting the cavity type fume purifier of fume, significantly promote surface area and the draught area of fume purifier of fume, enhancing is to the adhering to of oil smoke, condensation, separation, clean-up effect, reduce the wind loss of range hood, make more energy-conserving and environment-protective of range hood.
The below is described in detail content of the present invention.
