22 integrally connected shell, 2 corresponding inner surface and with positioned at the edge of housing inlet 21, annular lamina 22 and housing inlet 21
It corresponds, annular lamina 22 of the invention can also be fixedly installed in shell, depending on specific embodiment is with performance.
The effect of annular lamina 22 is that soot gas is made to generate vortex, while prevent soot particles from throwing away again when entering shell 2
During oil smoke subassembly 1 exterior space is thrown away from the housing inlet 21 of shell 2.
Exhausting component 5 is provided with wind turbine, wind wheel and spiral case, and wind turbine is assemblied in inside spiral case, and wind wheel is sequentially connected with wind turbine,
The air inlet that spiral case is fixedly installed in smoke machine body interior spiral case is communicated with the gas outlet of 11 top of concentric tube, the gas outlet of spiral case
It is communicated with the gas outlet of smoke machine main body, shell 2 is spherical housing 2.
The operation principle of the kitchen ventilator is：Kitchen ventilator is opened, motor 4 drives oil smoke subassembly 1, the wind wheel of exhausting component 5
It rotating simultaneously, soot particles are by seven layer separations inside kitchen ventilator, and most almost the gas of cleaning is discharged again through gas outlet finally,
As shown in Figure 5.This seven layer separation is specific as follows：
First layer separation, inertial separation：Oil smoke enters via the housing inlet 21 of shell 2 inside smoke machine, and oil smoke enters
Enter annular lamina 22 after housing inlet 21, because of 2 inside of shell and 21 area of pressure differential and housing inlet of external environment
Cataclysm, air velocity can accelerate, and moment of inertia also relatively increases.And oil smoke can form very thin around annular lamina 22
Boundary layer, and because the housing inlet 21 and annular lamina 22 of shell 2 are in angle, oil smoke is forced to flow downward along annular lamina 22
Just up flow into oil smoke subassembly 1 afterwards, thus heavier oil opened in downward inertia motion with crude oil plume field point it is past
The oil collector sump tank 3 in 2 bottom of shell is collected in lower movement, realizes first time inertial separation.
Second layer separation, cyclonic separation：Soot particles by the first layer separation are in the direction of annular lamina 22 by lower turn
Flowing in further occur flow field separation, soot particles flow field detach under cause unsteady flow field, be further formed vortex.
Flow field or vortex can interact influence with neighbouring flow field or vortex, and the flow field for not stopping spinning is formed in annular lamina 22, this
When rotating vortex reach maximum vorticity.The lighter oil smoke of remaining part can not be parked in the rotating vortex accumulation of annular lamina 22, when
When running up to constant weight, flow field branch is unable to hold out the weight of oil droplet, will fall downwards or flow to oil collector sump tank along annular lamina 22
3。
Third layer separation, centrifugal force separate：Eaves portion structure 13 follows the rotation of concentric tube 11 to form centrifugal force, centrifugal force and wind
The attraction interaction of wheel.After second detaches, the lighter oil smoke of remaining part is first contacted when entering concentric tube 11
Outermost end to eaves portion structure 13 enters back into concentric tube 11, and the centrifugal force of 13 outermost end of eaves portion structure can be segment fluid flow or oil
Smoke particle is taken away or stops into 11 inside of concentric tube and move outward, then thrown away with higher tangential velocity, is thrown out of particle
It can fall in annular lamina 22, oil collector sump tank 3 is flow to finally along annular lamina 22.
4th layer separation, inertial separation and centrifugal force separate：After third layer separation, the oil smoke of remaining lighter weight is same
When acted on by centrifugal force and attraction, but opposite attraction is more than centrifugal force.A portion of these oil smoke can be through
It crosses through-hole 131 to flow to adjacent eaves portion structure 13, because effect of inertia and other oil smoke or soot particles pool larger oil
Smoke particle flow down, but because centrifugal force acts on, soot particles are simultaneously flowed with being thrown away compared with high tangential velocity finally along annular lamina 22
Move oil collector sump tank 3.
Layer 5 detaches, the cyclone centrifugal force of concentric tube 11 and the secondary generation that is vortexed：11 inner wall of concentric tube rotates to form gas
Rotation, concentric tube 11 be low-pressure area under the action of the centrifugal force, fluids within pipes or particle etc. are moved toward duct wall, and tube wall forms height
Tangential velocity, part oil smoke are blocked flowing up.It is vortexed, does not stop in addition, remaining oil smoke can be formed in vortex generator
Spinning captures oil smoke and oil smoke is not allowed to flee from pipeline.After attraction and centrifugal force remove, do not stop spinning secondary vortex flow and
The oil smoke that high tangential motion is carried out in tube wall can be collected because gravity flows downward to oil collector sump tank 3 along inner tubal wall.
Layer 6 detaches, and disturbing flow device 111 detaches：The disturbing flow device 111 of 11 one end of concentric tube generates remaining oil smoke
Flow field separation occurs, is detached by flow field, part oil smoke because stopping during the unstability in flow field not toward flowing in length and spin
The vortex turned captures oil smoke.
Layer 7 detaches, wind wheel centrifugal force separate：After the first six layer separation, be left a small amount of very light soot particles because
Pressure differential and the wind wheel for sucking exhausting component 5, the wind wheel of rotation form centrifugal force and remaining a small amount of soot particles are thrown to wind turbine
Inner wall on, last almost clean gas is discharged external through gas outlet.
The material for having a variety of thermal conductivity factors different of the oil smoke subassembly 1 of the kitchen ventilator has kitchen ventilator different
Temperature field, rapid condensation oil smoke substantially increase oil-collecting ability.The oil smoke subassembly 1 also has to generate soot gas and add simultaneously
Centrifugal force, can effectively remove soot particles, be avoided that and contacted containing a large amount of soot particles gases with wind wheel, greatly improve oil smoke grain
The noise that the separating effect of son and reduction generate due to wind wheel accumulates oil stain.
