The specific embodiment
As Fig. 3 to Fig. 5-2-1 is the embodiment 1 of gas of the present invention and the contrary automatic cleaning fan of sucking oil fume of mixed flow of liquid net: comprise a suspended hood 1, a filter screen case 2, an air box 3, the filter 4 that is arranged in filter screen case 2, the blower fan group 5 that is arranged in air box 3 and cleaning device 6.
Suspended hood 1 is the below that is positioned at whole smoke exhaust ventilator, and its middle part forms an inlet scoop 12, is inhaled in the smoke exhaust ventilator with the oil smoke that makes the kitchen range top, and this suspended hood is provided with various control buttons 11 and lighting device (not shown).
When smoke exhaust ventilator normally uses, open starting switch and get final product work.
And need carry out cleaning to smoke exhaust ventilator the time, in service sink 65, place the finite concentration cleaning fluid, open the switch of cleaning device 6, starting the pump 66 of diving starts working, cleaning fluid is under the effect of the pump 66 of diving, cleaning fluid in the service sink 65 is through the pump 66 of diving, be conveyed into drain pipe 61 by feed pipe 64, the cleaning fluid that is penetrated by mouth spray 61 jet flows is divided equally spontaneous current to two filter 4 upper ends again, two filters 4 that formed by the folded screen pack of multilayer are made as the camber line face, being beneficial to cleaning fluid does not drip, and it is mobile naturally in screen pack at a slow speed to reach cleaning fluid, under the effect of own wt, by the last trickling naturally downwards along filter 4 upper ends, owing to form the effect of the screen pack of filter 4, cleaning fluid can form surface tension on each mesh, and cleaning fluid can form very thin on filter 4 and admire curtain along the plate mobile cleaning fluid that faces down, and wanders on the backflash 62, flow back in the service sink 65 by cleaning fluid backflash 62 again, form the circulating path of a cleaning fluid with this; Motor 51 energising work when air box 3 apoplexy units 5, it drives fan blade 52 and rotates, make filter screen case 2, form negative pressuren zone in the air box 3, the oil smoke of outer and suspended hood 1 below of smoke exhaust ventilator is by 12 strum boxs 2 and air box 3 from the inlet scoop, when passing mesh that the folded screen pack of multilayer constitutes filter 4 with combined mobile cleaning fluid curtain, mixed soot gas by contrary the friction, injected formation gas and liquid mixture, or soot gas is cleaned the slight bubble moment bag cage of liquid generation formation with shattered to pieces, soot gas is cleaned in mixed flow by fully adverse current mixing; With it simultaneously, the inside that forms negative pressuren zone in filter screen case 2, the air box 3 produces mobile gas and the liquid that rolls, cleaning fluid together converges and is back to backflash 62 to service sink 65, soot gas is cleaned by fully contrary mixed flow once more, circulation and so forth, soot gas are fully cleaned clean once more along mixed flow.Therefore, smoke exhaust ventilator structure of the present invention makes and takes out, inside and outside the fuselage in the suction, mist extractor ventilating duct flow process, no longer include the greasy dirt grease and pile up; Make it to reach gas and liquid cleaning reaction process that the contrary mixed flow of soot gas and cleaning fluid is formed.So both realized pumping the purpose of oil smoke, and reached the purpose of the folded screen pack of automatic cleaning multilayer again, the folded screen pack of multilayer can be pulled down cleaning, and no greasy dirt grease stops up; The gas of discharging does not have secondary pollution environment such as greasy dirt oil smoke, and the gas of backflow also is that cleaning is clean, makes internal and external environments such as kitchen and people no longer suffer the worry of fume pollution, avoids the trouble of the many cleanings of user.
Cooperate shown in Figure 4ly, can be provided with infrared observation in the service sink 65 of this cleaning device 6 and control blowdown apparatus automatically, dirty efficient to guarantee the wash oil tobacco tar, cleaning control is at best clean conditions; Also be provided with the micro computer automaton on this service sink 65 to add up to regularly blowdown apparatus or timing alarm prompting blowdown apparatus, dirty efficient to guarantee the wash oil tobacco tar, cleaning control is at best clean conditions; The intermittently regularly start and stop of the latent pump 66 of this micro computer automaton control are folded screen pack oil smoke greasy dirt to guarantee the batch cleaning multilayer simultaneously, make the little resistance of air-flow by combined cleaning fluid curtain, and cleaning control is at best clean conditions; But further be provided with the liquid level of a ball-cock assembly 651 Automatic Positioning Control cleaning fluids in the service sink 65, guaranteeing the sufficient quantity of cleaning fluid, and guarantee timely cleaning function; Also design a liquid level in this service sink 65 and cross and overflow from flow control device, with the floating greasy dirt of guaranteeing to be produced when the wash oil tobacco tar is dirty, the discharge dirt that can flow automatically automatically makes it in time to keep cleaning cleannes, and can prevent that cleaning fluid from overflowing on the service sink mouth; In addition, can design the temperature control automatic heating device in the service sink 65, make things convenient for heated wash, when using, can both reach this cleaning of ability of efficient cleaning in order to the zones of different Various Seasonal.Moreover, also be provided with automatic additional clean agent control device in this cleaning device 6, to guarantee the cleaning concentration of cleaning fluid in running, make it to reach the reaction that quick appearance is separated greasy dirt, oil smoke; This automaton is the glittering suggestion device of light modulation of newspaper sound automatically or reports the sound prompt device that rings automatically, can both give full play to its normal operation to guarantee every control device.Also can be provided with the convenient aperture mirror of observing the cleaning fluid cleannes on the side of this service sink 65.
The embodiment 2 of the smoke exhaust ventilator that the contrary mixed flow of gas of the present invention shown in Fig. 6,7 and liquid net cleans automatically: it comprises a suspended hood 1, a filter screen case 2, an air box 3, the filter 4 that is arranged in the filter screen case, the blower fan group 5 that is arranged in air box 3 and cleaning device 6 equally.
Itself and embodiment 1 same structure are not given unnecessary details at this; Different is the service sink 65 of cleaning device 6, and backflash 62 is provided in a side of on the inwall of filter screen case 2 lower ends, is connected with service sink 65 by return duct 63, can realize the function of automatic cleaning fan of sucking oil fume equally.
Be illustrated in figure 8 as the embodiment 3 of the contrary automatic cleaning fan of sucking oil fume of mixed flow of gas of the present invention and liquid net, what they were different with the foregoing description 1 is that filter screen case 2 and air box 3 are made as movable removable structure, and cleaning device 6 is set to the independent body structure that divides, and each partly connects by corresponding pipeline.
