Description
Technical field
The present invention relates to household technology for cooking fume control field, specially a kind of household novel jet flow formula fume purifying for kitchen use
Device.
Background technology
Jet refers to fluid and projected from the mouth of pipe, aperture, slit, or by mechanical driven, and with a plume of surrounding fluid blending
Body flows.The large Reynold number jet frequently encountered is usually the free turbulence without Gu Bi constraints, and this turbulent jet passes through border
Surrounding fluid volume is sucked in and constantly expanded by upper active turbulent closure scheme, and downstream, jet is in water pump, steam pump, logical for cocurrent
Many technical fields such as blower fan, chemical industry equipment and jet plane are used widely, and oily substance imperfect combustion deposits
Thin and loose black coal cigarette, can be used to make ink, ink etc..
The oil smoke that our usually cookings give out be edible oil and food under the high temperature conditions, caused a large amount of thermal oxides point
Solve product.During the cooking, grease is heated, and when temperature reaches 170 DEG C of the smoke point of edible oil, the blue smoke mist of decomposition at initial stage occurs,
As temperature continues to raise, decomposition rate is accelerated, and when temperature is up to 250 DEG C, a large amount of oil smoke occurs, and with pungent smell,
At 0.01 micron -0.3 micron, the oil smoke sample for the frequent deep fried foodstuff that relevant department collects from residential households enters oil smoke granularity
Row analysis, measures more than 220 kinds of chemical substance altogether, wherein mainly there is aldehyde, ketone, hydrocarbon, aliphatic acid, alcohol, aromatic compound, ester, interior
Ester, heterocyclic compound etc..It has also been found that the known mutations carcinogenic substance such as volatile nitrosamine in cooking fume.
Due to many oil smoke can be produced when kitchen is prepare a meal, oil smoke is all typically now carried out using lampblack absorber
Absorption, but oil smoke absorb after need carry out cooking fume purification handling.

And understand the present invention, and it is not used to the limitation present invention.
Embodiment：
As shown in Figures 1 to 4, the invention provides a kind of household novel jet flow formula fume purifier of fume for kitchen use, including purification
Case 1, collection box 2 and filter chamber 3, described one end of purifying box 1 are provided with ejector 4, and the ejector 4 passes through exhaust tube 5 and mistake
Filter chamber 3 is interconnected, convenient directly to be extracted out the cleaned air inside filter wall room 3 by exhaust tube 5；
The collection box 2 is arranged on the other end bottom of purifying box 1, and the side of purifying box 1 is provided with air inlet 101, it is described enter
The outer ring of gas port 101 is connected with baffle-box 102, and the side of baffle-box 102 is connected with air inlet bucket 103, is buffered by setting
Case 102 so that oil smoke air first passes through air inlet bucket 103, then is entered by baffle-box 102 inside purifying box 1, enters in oil smoke
During 1 inside of purifying box, avoid oil smoke from entering directly into inside purifying box 1, effectively prevent that oil smoke is excessive and produces and is dropped in the kitchen range top
Or on pot so that kitchen more clean hygiene, using more cleaning；
The ejector 4 includes jet pipe 401 and jet pump 402, and the jet pump 402 is arranged gas stream by jet pipe 401
Go out, the jet pump 402 connects connection with exhaust tube 5 and is evacuated, and the jet pump 402 is divided by demarcation strip 409
Every, jet pump 402 is separated by demarcation strip 40, ensure purifying box 1 inside soot gas jet pump 402 will not be made
Into influence, jet pump 402 is played a very good protection；
The end of jet pipe 401 is provided with shower nozzle 6, is evacuated by jet change 402, exhaust tube 5 is by inside filter chamber 3
Air extract out, air sprayed by jet pipe 401, you can by the Air blowing inside purifying box 1 so that inside purifying box 1
Negative pressure is formed, oil smoke air is sucked；
When in the static situation that air draught is injected into purifying box 1, not there is speed not etc. in it between surrounding static fluid
Discontinuity surface, discontinuity surface are typically inevitably disturbed, and are lost stable and are produced vortex, and volume inhales surrounding fluid and enters incident flow,
Simultaneously constantly mobile, deformation, division produce turbulent fluctuation, and it influences gradually, and development forms the mixed layer of free turbulent fluctuation inside and outside,
Due to the lateral transport of momentum, the fluid being involved in obtain momentum and with former jet flow forward, fluid momentum originally reduce and
Lose speed, form certain velocity gradient, volume inhales and the result of blending, and jet flow section constantly expands, and flow velocity then constantly drops
Low, oil smoke air is pumped into inside purifying box 1 along Cheng Zengjia by flow by air inlet bucket 103, afterwards in the presence of jet,
Enter inside collection box 2 and handled；

Connection, is fixed baffle-box 102 by mounting seat 104, while rubber blanket 105 ensures sealing, prevents baffle-box 102 from leaking
The situation of gas, while mounting seat 104 connects with the spiral inner wall of air inlet 101 of purifying box 1, is easy to dismantle baffle-box 102, just
Cleaned inside to baffle-box 102；
As described in Figure 1, the side of jet pipe 401 is provided with branched pipe 404, and piston is provided with inside the branched pipe 404
405, the piston 405 is promoted by piston rod 406, and the top of piston rod 406 is pushed away by electric pushrod 407
Dynamic, the electric pushrod 407 is fixed on the inwall of purifying box 1 by fixed seat 408, and piston rod is promoted by electric pushrod 407
406 so that piston rod 406 promotes piston 405, you can the gas inside branched pipe 404 is extruded, passes through pushing away for branched pipe 404
It is dynamic, improve the power of jet pipe 401 so that jet air flow velocity faster, realizes preferably clean-up effect；
As shown in figure 3, the bottom of U-tube 204 is provided with and changes liquid pipe 7, the liquid pipe 7 of changing passes through sealing ring 8 and U-tube 204
It is tightly connected, the surface of liquid pipe 7 of changing is provided with control valve 9, U-tube 204 is carried out to change liquid by changing liquid pipe 7, works as U-tube
After liquid inside 204 is contaminated, control valve 9 is opened, the liquid inside U-tube 204 is discharged, conveniently changes water, is improved net
Change effect.
The jet pump 402 is fixed together by fixed mount 403 and purifying box 1, convenient to fix jet pump 402, more
Add stabilization；
The filter chamber 3 is internally provided with activated carbon filter layer 301, and the side of filter chamber 3 is provided with filter plate 302, the filter
The surface of plate 302 uses cavernous structure, and when exhaust tube 5 is evacuated, filter plate 302 filters out the debris in air, while activated carbon
Filter layer 301 carries out purified treatment to air, effectively improves the clean-up performance of air, and oil smoke is being carried out only by jet air
When change, secondary pollution effectively prevent so that clean-up effect greatly improves.
In summary, the main characteristic of the invention lies in that：
（1）Oil smoke is drawn into inside purifying box, entered by immixture by setting ejector by the present invention using air-spray
Enter to inside collection box, handled successively by collecting tank and process tank, you can complete overall Oil-gas Separation, realize oil smoke
Purified treatment, processing after directly discharge, it is simple and convenient；
（2）The present invention is improved by setting U-tube to carry out purified treatment to the air for separating oil smoke by after-treatment mode
Air quality, purification efficiency is improved, and noise will not be produced during overall work, use is safer, few using consumptive material, service life
Extend；
（3）The present invention greatly improves, fume purifying is more thorough compared to traditional purification style to the purification efficiency of oil smoke air
Bottom, meet green requirement, and caused corrosivity is smaller in itself to device, is hardly damaged.
