Abstract

The utility model relates to an environmental protection fume exhaust fan, which comprises a shell and a discharge fan. The utility model is characterized in that a purifying sealed chamber is fixed in the shell, the lower end of the purifying sealed chamber is opened, the lower part of one side of the purifying sealed chamber is provided with a fume hole which corresponds to a fume hole on the side of the shell, and the fume hole on the purifying sealed chamber is communicated with a fume pipe on a discharge fan which is arranged on the outside of the shell; one group or more than one group of filter core plates are horizontally fixed in the purifying sealed chamber. The utility model has the advantages that multi-stage purification and filtration function to the fume is provided; no oil dirt is silted on a fume exhaust system; no pollution is produced to the external environment; the structure is simple; the whole fume exhaust system does not need cleaning but changing the filter core plates annually.

Description

Environment-friendly range hood

The utility model relates to a kind of air regulator, especially a kind of kitchen lampblack absorber.

At present, the smoke exhaust of known kitchen, its principle is by draught fan impeller rotation, produces certain inspiratory flow near the lampblack absorber mouth, oil smoke is sucked the smoke exhaust flue after, directly drain into outdoor.The running of this lampblack absorber only is simple suction process, and drains into the still environment formation harm to external world of outdoor oil smoke, and the smoke evacuation system of its lampblack absorber directly contacts oil smoke, also causes the grease alluvial.

The purpose of this utility model provide a kind of have oil smoke multistage purification filtering function, no grease deposit in smoke evacuation system, to external world environmental nonpollution, simple in structure, only need to change the environment-friendly range hood that filters central layer and need not clean whole smoke evacuation system by the time limit.

The purpose of this utility model is achieved in that

The utility model comprises shell, exhaust blower, it is characterized in that: fix one in the enclosure and purify gas-tight silo, its lower ending opening, and a side lower part has exhaust smoke hole, corresponding with shell at the exhaust smoke hole of this side, and be connected with the smoke exhaust pipe of the exhaust blower that is installed in housing exterior, purify that horizontal fixed has a group or more to filter central layer in the gas-tight silo.

---purify the rear side that gas-tight silo is fixed on shell, its top, the place ahead and left and right sides all maintain certain clearance with the shell inboard.

---filter the sandwich plate of central layer for constituting by upper and lower plate, one of them plate is bigger than another, to form outer eaves, should seal with purifying gas-tight silo by outer eaves, thereby form flue, have a cigarette hole in the middle of the big plate at the periphery that purifies gas-tight silo, with this cigarette hole is in the interlayer of center between upper and lower plate, constitute the annular flue that the multiple tracks external diameter does not wait by adsorption bar, the sidewall of adsorption bar has the hole alternately, and each annular flue is connected.

But---filter the central layer series and parallel and be installed in the purification gas-tight silo.

---be provided with one and fall the blast device above the escape pipe of exhaust blower, these device two ends have through hole, have filled adsorbing sphere in it.

The utility model is owing to adopt said structure, when opening lampblack absorber, the oil smoke that expansion is risen is up with the flue that purifies the formation of gas-tight silo periphery along shell, after oil smoke walks to the top that purifies gas-tight silo, be filtered central layer and be drawn into the interior not isometrical annular flue of interlayer, and under the suction force effect of exhaust blower, constantly change wind speed, blast and flow direction, tobacco tar in the oil smoke is fully adsorbed be trapped on the annular flue that filters central layer, thereby oil smoke is filtered and adsorbs.The exhaust smoke hole discharge that gas after the filtration is opened through purifying gas-tight silo one side lower part by exhaust blower.

Shell is inboard makes flue with purifying the gas-tight silo periphery owing to adopt, and the oil smoke that rises expanding linearly rises and siphons away, and so just forms a closed airflow barrier at the lampblack absorber periphery, has controlled the oil smoke diffusion, has spread, and has improved the oil suction efficient of lampblack absorber.Owing to can adopt many groups to filter central layer, realized the multistage adsorption filtration of oil smoke, reached the environment protecting of lampblack absorber smokeless emission; Owing to adopted the filtration central layer, make lampblack absorber only need change the filtration central layer, just can reach the purpose of maintenance, saved the trouble of cleaning the lampblack absorber smoke evacuation system.

Below in conjunction with drawings and Examples the utility model is further described:

Fig. 1 is a front view of the present utility model.

Fig. 2 is for filtering the partial sectional view of central layer.

Fig. 3 is for filtering the structure chart of central layer.

Fig. 4 filters the P-P of central layer to cutaway view.

See Fig. 1, purification gas-tight silo 1 is fixed on the rear side in the shell 3, and its top, the place ahead and left and right sides all maintain certain clearance with shell 3 inboards; Its lower ending opening, and a side lower part to have an exhaust smoke hole 11 corresponding at the exhaust smoke hole of this side with shell 3, and be connected with the smoke exhaust pipe (drawing among the figure) of the exhaust blower 4 that is installed in shell 3 outsides, purify that horizontal fixed has three groups to filter central layers 2 in the gas-tight silo 1.

See Fig. 2-4, filter the sandwich plate of central layer 2 for constituting by upper plate 21, lower plate 22, wherein upper plate 21 is bigger than lower plate 22, to form outer eaves 25, this outer eaves 25 and 1 sealing of purification gas-tight silo, thereby purifying gas-tight silo 1 periphery formation flue, having a cigarette hole 24 in the middle of the upper plate 21, is in the interlayer of center between upper plate 21, lower plate 22 with this cigarette hole 24, constitutes the annular flue that the multiple tracks external diameter does not wait by adsorption bar 23, the sidewall of adsorption bar 23 has hole 26 alternately, and each annular flue is connected.

Also be provided with one and fall blast device 5 above the escape pipe of exhaust blower 4, these device two ends have through hole, have filled adsorbing sphere in it.Falling blast device 5 can increase or remove as required
