It is communicated with the gas outlet of smoke machine main body.
The operation principle of the kitchen ventilator is：Kitchen ventilator is opened, motor 4 drives oil fume separator 1, the wind wheel of exhausting component 5
It rotates simultaneously, soot particles pass through seven layer separations inside kitchen ventilator, and most almost the gas of cleaning is discharged through gas outlet again finally.
This seven layer separation is specific as follows：
First layer separation, inertial separation：Oil smoke enters via the air inlet 21 of filter device 2 inside smoke machine, and oil smoke enters
Enter annular lamina 22 after air inlet 21, because rapid with 21 area of pressure difference and air inlet of external environment inside filter device 2
Become, air velocity can be accelerated, and moment of inertia also relative increases.And oil smoke can form very thin boundary around annular lamina 22
Layer, and because air inlet 21 and the annular lamina 22 of filter device 2 are in angle, force oil smoke along annular lamina 22 to flow downward after
Oil fume separator 1 is up flowed into, therefore heavier oil is separated with crude oil plume field in downward inertia motion and transported down
The dynamic oil collector sump tank 3 collected in 2 bottom of filter device, 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 pumping
The attraction of wind component 5 interacts.After second detaches, the lighter oil smoke of remaining part is first when entering concentric tube 11
The outermost end for touching eaves portion structure 13 enters back into concentric tube 11, the centrifugal force of 13 outermost end of eaves portion structure can segment fluid flow or
Person's soot particles take away or stop into 11 inside of concentric tube and move outward, then are thrown away with higher tangential velocity, are thrown out of
Particle can be fallen in annular lamina 22, and 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 by centrifugal force and attract force effect, but opposite attraction be 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 centrifuging force effect, 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, and the cyclone centrifugal force of concentric tube 11 and secondary vortex generate：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, which is blocked, to be flowed up.It is vortexed, does not stop in addition, remaining oil smoke can be formed in vortex generator
Spinning captures oil smoke and does not allow oil smoke 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 is stopped not because of the unstability in flow field 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 difference 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 filter device 2 of the kitchen ventilator has and the inside machine from face protection oil smoke will be isolated with external environment inside smoke machine
Part, while filtering fume can be crossed, reduce production cost.The kitchen ventilator is detached with the oil smoke of the kitchen ventilator than the prior art simultaneously
Device 1 generates additional centrifugal force, can effectively remove soot particles, avoids soot particles from entering exhausting component 5, is avoided that containing oil smoke
Particle is contacted with wind wheel, greatly improves the separating effect of soot particles.
Embodiment 2.

The filter device 2 for applying example is metal plate filter device 2.
Embodiment 1 is compared, and metal plate filter device 2 has conduction, heat-resisting advantage.
Embodiment 3.
A kind of kitchen ventilator with on-plane surface filter device, other features are same as Example 1, the difference is that：This reality
The n=4 of example is applied, i.e. the concentric tube 1111 of the present embodiment is provided with 4.The present embodiment m=2, i.e. vortex generating means group 14 are set
2 are set to, one is set to the 4th concentric tube, another is set to the 3rd concentric tube.The concentric tube 11 and eaves of the present embodiment simultaneously
Portion's structure 1313 corresponds.
The kitchen ventilator with on-plane surface filter device compared with Example 1, increases a concentric tube 11, that is, increase
