Embodiment 1

Fig. 1 illustrates a kind of no dirty aspiration lampblack absorber (or being called smoke exhaust ventilator), wherein, at the rear portion of the blast pipe of this range hood two-filtration devices is installed.

As shown in Figure 1, during work, the strong high-speed wind power of utilizing the fan 1 be installed in the range hood outer cover 12 and fan 2 to be produced can be aspirated hot gas such as steam and oil smoke together, produces a powerful air-flow, flows into then in the narrow blast pipe 3 of gradually closing.Is to make gas in flowing produce injection that suppressing effect of contracting and high pressure to blow power with this pipe design for the purpose that little by little narrows, because in the time of in Compressed Gas flows into duct formula casing 10, compressed gas is known from experience sharply, and expansion, pressure are multiplied, thereby make air-flow become a kind of high pressure and strong air-flow, and then effectively promote 4 rotations of air water mixed wheel.Because the part of the rotor block of air water mixed wheel 4 is immersed in the clear water of water tank 6, when it rotates, can produce the rotation water spout situation of a hollow ring shape, suction waste gas enters in it, thereby produce the desirable mixed effect of a useless G﹠W (or filter liquide), simultaneously, blade also can be pressed into air-flow and interior oil smoke, steam and hot gas etc. thereof in the clear water together, therefore hot gas and oil smoke can be cooled off by clear water, thereby make hot gas such as vaporific elaioleucite and steam be converted back into liquid state and be attached on the self finish.The structure of water tank 6 is a kind of modularized designs, can dismantle freely, can where necessary it be unloaded sewage is outwelled or it is cleaned, and its first half is equipped with air water mixed wheel 4, and Lower Half is used for loading clear water or various sterilization filter liquide.Water in the water tank 6 or various sterilised liq can play the effect of filtration.Dispose of sewage for convenience, the present invention can be equipped with an oral siphon 8 and an outlet pipe 9 as shown in Figure 1, thereby can be easily with intermittent mode input clear water and sewage effluent.Water tank 6 can adopt transparent visual material manufacturing, and for example, transparent plastic and glass are with convenient concentration situation of observing sewage.Simultaneously, for anti-sealing or liquid flow backwards back in the blast pipe 3, near it exported, adding a section shape was leg-of-mutton anti-overflow sheet 23.

As shown in Figure 2, be equiped with water Lian formula sealing ring 5 respectively in the rotor block both sides of air water mixed wheel 4 of the present invention, its design feature and operation principle are to utilize a plurality of leg-of-mutton indent formula water storage cave 22 in its ring body to store clear water, when 4 rotations of air water mixed wheel, because centrifugal force relation, and the less reason of outlet, the clear water in the cave can throw away more slowly.And, because the distance between sealing ring and the duct housing is very little, add the tension force and the stickiness of water, thereby the obstacle that can produce one water Lian formula along with rotation intercepts and plays sealing effect, prevent that with this gas and oil smoke from leaking.Go to promote 4 rotations of air water mixed wheel in order to effectively utilize waste gas simultaneously, the blade of air water mixed wheel 4 is designed to arc section shape, adds that its middle part is interior curved section design, and monoenergetic does not improve the motive force of drawing waste gas, can also add impetus.Simultaneously, the clear water effect that stores momently also can be played in its blade back.When 4 rotations of air water mixed wheel, the clear water in the cave can produce the sealing watering effect of a vaporific spray between each blade, and the mixing that improves oil smoke and clear water contacts effect.Simultaneously also can guarantee when the situation of rocking, have enough clear water to remove mix waste gas.Simultaneously clear water can lubricate, helps the rotation of air water mixed wheel 4.

For the range hood of all size type, can need install a miniature motor additional by situation and drive air water mixed wheel 4, to prevent the motive force deficiency of jet-stream wind, influence the filtering oil smoke effect.

After hot gas and oil smoke were once filtered by clear water, the gas in the air-flow can be emerged from the clear water of water tank 6 owing to can not mix existence with clear water, flows to escape pipe 11 then.In order to prevent that the spray of beating that waste gas is produced when emitting ejection in the water tank exit from entering in escape pipe 11 or the active carbon filter 7, is equipped with the fish gill formula anti-overflow device 16 (its operation principle aftermentioned) of the section scultellum shape of a shaped form.Simultaneously active carbon filter 7 is installed in the pipeline of escape pipe 11, is used for the gas that emits ejection is carried out secondary filter.Filter 7 is a kind of filters of being made by the multilayer active carbon, utilize the multilayer active carbon to intercept and stick fine elaioleucite or water particle in the gas, simultaneously also filter liquide the pernicious gas that can not filter, and play the effect of the air-flow that slows down.This filter 7 can be dismantled freely with modularized design, can integral body takes out and changes or clean.

Hot gas that is produced when cooking and oil smoke are through the clear water cooling of water tank 6 and filter, and after filtering through filter 7, are discharged in the exit of escape pipe 11 again, and the gas of this moment becomes the gas that does not have heat and cleaning, thereby can directly discharge back indoor.For family range hood, can not need to install again long blast pipe, discharge waste hot gas outdoor.For the range hood of large kitchen, can need and the discharge open air by situation, but it can not give off strong oil smoke again, pollutes wall and the clothing or the atmosphere pollution of rear lane.

This shows that duplex filter design of the present invention can cooperate various traditional range hoods.
