The further improvement of technical solutions of the utility model is: mesh air inlet duct dividing plate outer wall being also provided with water spray.
The further improvement of technical solutions of the utility model is: lower header top and upper tank top are separately installed with screen pack.
The further improvement of technical solutions of the utility model is: also comprise the water gage being arranged on lower header sidewall.
Owing to have employed technique scheme, the technological progress that the utility model obtains is:
Cooking-fume exhauster without dismounting and washing of the present utility model, it can thorough filtering oil smoke, not needing people for unpicking and washing smoke exhaust ventilator, clean environment firendly, eliminating safe hidden trouble, health concerns.The utility model comprises range hood, flue, flue is positioned at above range hood, lower header and upper tank is provided with in flue, blower fan is contained in the flue above upper tank, and upper tank is arranged in the flue above lower header, has certain interval between upper tank and lower header, be called air chamber, flue is divided into and is positioned at exhaust air box and air chamber by upper tank, and exhaust air box is positioned at above upper tank, and air chamber is positioned at below upper tank.The continuous Exhaust Gas of blower fan makes air pressure in exhaust chamber lower than air chamber, in air chamber, air pressure is lower than atmospheric gas pressure, then cooking fume constantly pours in inlet plenum, successively through lower header, air chamber, upper tank, exhaust chamber, flue, wherein place the alkaline solution prepared in advance in lower header and upper tank, oil smoke and alkaline solution generation saponification, by oil smoke filtering, discharge the gas of purification from the outlet of flue.Cooking fume, by the effective filtering of alkaline solution, avoids the attachment of oil smoke on flue and blower fan, does not need to be taken apart by lampblack absorber, clean flue and blower fan; Because oil smoke is by alkaline solution filtering, lubricating cup is not set and collects, scrub lubricating cup so it also avoid to pull down.
Arrange air inlet duct dividing plate in the cooking fume porch of range hood, lower header is arranged on the top of surrounding's range hood of air inlet duct in flue, dividing plate, and the sidewall of lower header and air inlet duct dividing plate form the pond of splendid attire alkaline solution, are covered with return air cover above air inlet duct dividing plate; Return air cover is ridge, end face be middle high, from centre to the face that both sides (or around) is downward-sloping, meet the flow direction of gas in aerodynamics, be convenient to oil smoke gas quickly through, reduce the accumulation of oil smoke; The lower end, side of return air cover is stretched in the alkaline solution of lower header, if cooking fume condenses at the inner surface of return air cover wall, inclined-plane is conducive to liquid oil droplet and falls lower header.
The lower wall of upper tank is provided with the mesh of water spray, arranges the tube connector being communicated with lower header and upper tank, tube connector is provided with water pump between lower header and upper tank.When there is no external pressure, because surface tension liquid can not be descended Lou, after lampblack absorber is opened, pressure due to water pump pump water makes upper tank liquid with vaporific ejection, after oil smoke contacts with fog, be condensed into little oil droplet, will enter lower header fast, the gas of filtering oil smoke enters upper tank from air chamber.
Tube connector and upper tank are flexibly connected, and the sidewall of lower header are provided with filler, water gage, add alkaline solution from filler, and water gage monitors the liquid level adding solution; The tube connector be flexibly connected with upper tank, becomes the drainpipe of lower header when removing be connected with upper tank, the sewage of saponification is got rid of in timing, reduces the accumulation of greasy dirt, avoids the generation of health and potential safety hazard.
The going to the bottom of lower header is provided with thermal insulation board, the effect of the thermal insulation board cooking fume higher with temperature of being gone to the bottom by lower header lower for temperature is isolated, when the temperature difference is less time, the cooking fume that cooking stove can be avoided to produce lower header go to the bottom the quick end cooling condensation, thus reduce the absorption of lampblack absorber lower surface mist of oil, reduce clean workload.
Air inlet duct dividing plate outer wall is also provided with the mesh of water spray, by cooking fume herein through pretreatment, a part of oil smoke is met water-setting and is formed little oil droplet, falls lower header fast, accelerates the velocity of liquid assets of cooking fume, decrease cooking fume from the effusion air channel.
Lower header top and upper tank top are separately installed with screen pack, break up air-flow with screen pack, reduce bubble and produce, reduce smoke exhaust ventilator noise in use.
