End.The effect of disturbing flow device 111 is that soot gas is made to generate vortex, to improve the ability of de-oiling.
Concentric tube 11 is that the line segment being made of multistage broken line surround concentric tube 11 formed by axis one week, 11 inner wall of concentric tube
Adjacent two lines section intersection position be vortex occur position 16, such as Fig. 7.The effect of 11 shape of concentric tube of the utility model
It is that soot gas can be made to generate vortex in 11 inner wall of concentric tube, improves the efficiency of removing oil smoke.
The diameter of one end of concentric tube 11 is greater than the diameter of the other end.One end of concentric tube 11 is to connect with exhausting component 5
One end, as 11 gas outlet of concentric tube, the other end of concentric tube 11 is the air inlet of concentric tube 11, according to Venturi effect
It is found that the bigger flow velocity of area that fluid flows through is smaller, i.e., the speed of one end of gas concentric pipe 11 is greater than the another of concentric tube 11
Hold speed.Again according to Bernoulli's theorem it is found that the speed of gas to get over high pressure smaller, therefore concentric tube 11 and exhausting component 5 connect

The surface area of shell 2 is SShell 2, the gross area of housing inlet 21 is SHousing inlet 21, 0.1SShell 2≤SHousing inlet 21≤
0.5SShell 2。
The surface area that the gross area of the housing inlet 21 of the utility model accounts for shell 2 is being no more than 0.5, can reduce
Speed when soot gas enters inside kitchen ventilator reduces the pressure difference inside kitchen ventilator with external environment.Housing inlet 21
The gross area account for the surface area of shell 2 not less than 0.1, because housing inlet 21 is too small also to reduce absorption oil smoke

Exhausting component 5 is provided with blower, wind wheel and spiral case, and blower is assemblied in inside spiral case, and wind wheel and blower are sequentially connected,
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.
The working principle of the kitchen ventilator of the present embodiment is: kitchen ventilator is opened, rotating electric machine 4 drives oil smoke separation assembly 1,
The wind wheel of exhausting component 5 rotates simultaneously, soot particles inside kitchen ventilator by seven layers of separation, most almost clean gas finally
It is discharged again through gas outlet, as shown in Figure 6.This seven layers separation are specific as follows:
First layer separation, inertial separation: oil smoke enters inside smoke machine via the housing inlet 21 of shell 2, and oil smoke enters
Enter annular lamina 22 after housing inlet 21, because of 21 area of pressure difference and housing inlet of shell 2 inside and external environment
Cataclysm, air velocity can accelerate, and moment of inertia also relative increases.And oil smoke can form very thin around annular lamina 22
Boundary layer, and because shell 2 housing inlet 21 and annular lamina 22 be in angle, force oil smoke along annular lamina 22 will to flow down
Oil smoke separation assembly 1 is just up flowed into after dynamic, therefore heavier oil divides in downward inertia motion with crude oil plume field
Leave for lower movement collection in the oil collector sump tank 3 of 2 bottom of shell, realizes first time inertial separation.
Second layer separation, cyclonic separation: the soot particles by first layer separation are in the direction of annular lamina 22 by lower turn
Flowing in further occurrence flow field separation, soot particles flow field separate 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 of wheel interacts.After separating for the second time, 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, the centrifugal force of 13 outermost end of eaves portion structure can segment fluid flow or
Soot particles take away or stop to enter 11 inside of concentric tube and move outward, then are thrown away with higher tangential velocity, are thrown out of grain
Son can fall in annular lamina 22, flow to oil collector sump tank 3 finally along annular lamina 22.
4th layer of separation, inertial separation and centrifugal force separate: after third layer separates, the oil smoke of remaining lighter weight is same
When acted on by centrifugal force and attraction, but opposite attraction is greater 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, and because centrifugal force acts on, soot particles are simultaneously flowed with throwing away compared with high tangential velocity finally along annular lamina 22
Move oil collector sump tank 3.
Layer 5 separation, 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 mobile 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
It can be collected because gravity flows downward to oil collector sump tank 3 along inner tubal wall in the oil smoke that tube wall carries out high tangential motion.
Layer 6 separation, disturbing flow device 111 separate: the disturbing flow device 111 of 11 one end of concentric tube generates remaining oil smoke
Flow field separation occurs, is separated 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 separation, wind wheel centrifugal force separate: after the separation of the first six layer, be left a small amount of soot particles very light 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 blower
Inner wall on, last almost clean gas is discharged external through gas outlet.
The oil smoke separation assembly 1 of the kitchen ventilator can make gas generate vortex removing soot particles inside smoke machine, be avoided that
It is contacted containing a large amount of soot particles gases with wind wheel, improve the separating effect of soot particles and avoids generating because wind wheel accumulates grease stain
Noise.

A kind of kitchen ventilator with oil smoke separation assembly, as shown in figure 5, other features are same as Example 1, difference exists
In: oil smoke separation assembly is provided with sheet metal 15, is assemblied in the surface of vortex generating means group 14.The effect of sheet metal 15 is temperature
Spend relatively high oil smoke by can condense because the surface temperature of sheet metal 15 is low when sheet metal 15 made of metal material thus
Separate oil smoke.
Compared with Example 1, soot gas is easier to separate in vortex generating means group 14 the present embodiment.
Embodiment 3.
A kind of kitchen ventilator with oil smoke separation assembly, other features are same as Example 1, the difference is that: this implementation
