Background technology
Lampblack absorber in the market is the suction of vane type and the oil droplet in the inertial separation oil smoke basically, and setting height(from bottom) is that the distance of suction inlet and kitchen range face is generally 600-750mm.
Because the suction wind speed in the outside, inlet scoop has the overdamp characteristic, when the inlet scoop wind speed was 20m/s, effectively the air draught distance had only one times inlet scoop diameter.For existing lampblack absorber, if the inlet scoop diameter is 200mm, the suction wind speed is 4m/s, and then it effectively sucks distance less than 200mm.In order to improve suction effect, generally on petticoat pipe and lampblack absorber setting height(from bottom), think hard.For example, the front panel of the petticoat pipe of patent CN200510024074.X adopts material transparent, makes the lampblack absorber setting height(from bottom) than common low 200-300mm; The extending shortening of the petticoat pipe of patent CN200410008184.2, oscilaltion can cover cooking stove (gathering hole can open and close), in the oil smoke seal bootr, makes oil smoke suck clarifier as far as possible.In addition, in order to improve suction effect, there is a kind of like this trend in manufacturer at present, is exactly to strengthen the suction air quantity simply, and air quantity is by the 7m of GB
3/ min is increased to 12m
3/ min, even 15m
3/ min.But working as air quantity exactly is 15m
3During/min, suck wind speed and have only 8m/s, suction effect produces little effect.
If fruit says that existing lampblack absorber suction effect is passable, its fume purifying function is just very weak, is rotated in the inertial separation that produces in the impeller turned cavities because its oil smoke separation is based on impeller.Because the axial distance of impeller turned cavities is very little, the oil smoke time of staying is very short, and most of oil droplet has little time to arrive wall and just taken out of the impeller turned cavities, thereby discharges from blast pipe.In order to improve clean-up effect, some patent considers to add silk screen or other filter mediums, adds braiding silk screen (or book plate pressing mesh) as patent CN200410034548.4, and patent CN200510050361.8 adds filter medium.But because the oil viscosity in the oil smoke is very big, filter medium is blocked easily inevitably.
In addition, existing lampblack absorber, its impeller directly contacts with oil smoke.After normally using one or two years, be stained with sump oil on the impeller, influence its dynamic balancing, increase rotational resistance, reduce rotating speed, reduce air quantity, effect descends.To be stained with greasy dirt be exactly an illustration for table top, cabinet in the kitchen.CN200310124169.X adopts jet fume exhausting type that blower fan and oil smoke are isolated, and utilizes blower fan to send air in the oil smoke cover outside, produces the air-flow that revolves at the bottleneck of smokejack, oil smoke is inhaled involved in smoke discharging pipe.But this mode is only taken off row function, does not have purification function.Patent CN02125656.X also utilizes cyclone technique, but also has only certain row's effect of taking off.The cyclone pipe of patent CN01120562.8, interior band helical duct, complex structure, the time has been grown pipe inner product oil, and this patent does not propose to inhale, row's scheme, is difficult to implement.Patent CN92102246.8 and patent 91108847.4 are the split type of blower fan and cyclone pipe, and suction line is long, and loss of vacuum is big, influences suction force.
Other has patent, application number 200610039320.3, and a kind of oil smoke separating machine, separating cyclone tube resistance wherein is big, and is single inlet, and the flow field symmetry in the separating cyclone tube is relatively poor, influences the isolation of purified effect.
