Moreover, the air exhaust port of the regeneration cycle device of the utility model system is mounted on the smoke exhaust leading edge and towards cooking machine (gas range) the place ahead, the wind that air the formed screen of its discharging, just can stop the when cooking institute oil smoke that produces to around the excessive phenomenon of loosing, make oil smoke be entirely smoke exhaust and absorb.That is to say, the utility model comprises the air trunking of the top that is placed in range hood, the inlet port of this air trunking and the exhaust outlet of range hood are with sealed connection, its outlet places the leading edge of range hood, and in air trunking, set gradually rinsing machine and air exchange mechanism from the inlet port end, this rinsing machine comprises and is parallel to treatment element and the air exhauster that the range hood exhaust flows to, and this air exchange mechanism comprises and is positioned at the floss hole after the rinsing machine outlet and is positioned at that air trunking is terminal partly can to suck the lift pump that outside air enters ventilation duct.

Relevant structure of the present utility model and embodiment, conjunction with figs. is described as follows now: the accompanying drawing simple declaration:

Fig. 1 is the structure and the embodiment schematic diagram of the utility model.

See also Fig. 1, generally speaking, range hood 1 reaches the highest for making the efficient that absorbs oil smoke, all be installed on the top of cooking machine (gas range) 2, has sloping baffle 12 in this range hood 1, this baffle plate 12 intersects at upright center line mutually, and with spaced-apart and related angle displacement shape configuration, make sloping baffle 12 omit the current path of curl, therefore after the running of the air compressor machine of range hood 1, the oil smoke that the cooking is produced is sucked in sloping baffle 12, make oil smoke be the form of eddy current and increase the interparticle collision opportunity of the contained grease of air, therefore, most grease is all this range hood 1 and assembles in the air, and discharges fully according to the air that mat exhaust outlet 11 will be handled.Above-described all is the oil smoke removing method and the main composition in general kitchen and kitchen, large-scale premise.And the part that the utility model proposed is means and the structure of handling again at the air that exhaust outlet 11 is discharged, and below just illustrates one by one that it constitutes and better embodiment in detail.

Please continue to consult Fig. 1, the inlet port 31 of air trunking 3 of the present utility model, system engages with the exhaust outlet 11 of aforementioned range hood 1 with sealing relationship, make the gas of being discharged to receive by air trunking 3 fully from exhaust outlet 11, and unlikely leaking in indoor, the other end at air trunking 3, promptly export 32 and be good (this point to be installed on range hood leading edge 13, be detailed later), and, but the rinsing machine 5 of the remaining oil quantity of configuration one filtering air trunking, 3 air in the air trunking 3, the inlet 50 of this rinsing machine 5, system sucks the air of discharging from exhaust blower 1 fully, the air system form slightly in the shape of a spiral that its wash water machine 5 is sucked, therefore entering the mouth, the side needs storing one cowling panel 51 to make the flowing of air that uniformity be arranged after 50, spray according to mat fountain head 52 again, the grease grain that makes in the air to be loaded with washing away cooling and drops through hydrone, and after cassette grease catcher 53 gives the filtering grease, through water fender 54 airborne moisture content is screened out again, at water fender 54 rears aluminium matter screen pack 55 is arranged more, after airborne impurity filtering, comply with by blower fan 56 again air is discharged, and in outlet 57, remove airborne stink with an activated carbon filter screen 58.Aforementioned a series of filtering process makes grease, impurity, the dust of being loaded with in the air, and stink is eliminated fully.
