Place.Rotor unit is connected to the inwall of housing component 4 by bearing arrangement.Fig. 4 is to obtain along the axle center cutting fan assembly of impeller
The sectional view arrived.
The variation tendency that the sectional area of air intake passage changes from small to big in elder generation from air inlet 5 to air outlet 6 the most again.What is called " is entered
The sectional area of wind passage " it can be understood as: to be perpendicular to the air intake passage that the face in the axle center of impeller obtains to cut air intake passage
The area in cross section.The sectional area of the air inlet 5 of air intake passage is more than the sectional area of the air outlet 6 of air intake passage.Air intake passage
Minimum sectional area between air inlet 5 and air outlet 6, and closer to air outlet 6.
Stator unit includes multiple winding 1 and multiple iron core 2, each winding 1 and each iron core 2 one_to_one corresponding, each winding 1 all with
Its corresponding iron core 2 forms winding module.The axle center of each winding module wound impeller is evenly distributed is fixed on housing component 4
On outer wall, as shown in Figures 1 to 3.Stator unit is arranged relative to oil smoke channel seal, and i.e. stator unit is relative to air intake passage
Seal and arrange, so that being isolated with oil smoke with stator unit under state.
After winding 1 energising of stator unit, producing rotating excitation field, this rotating excitation field drives permanent magnet rotating, due to permanent magnet
Being fixed on impeller, impeller is just directly rotated by and then produces negative pressure in this rotating excitation field, and oil smoke is at the work of this negative pressure
Air intake passage (flowing into the oil smoke of air intake passage as shown in dotted line A in Fig. 3 from air inlet 5), oil smoke is flowed into from air inlet 5 with lower
(flowing out the oil smoke of air intake passage as shown in dotted line B Fig. 3 from air outlet 6) is flowed out from air outlet 6 after flowing through air intake passage.This
The impeller of smoke exhaust ventilator embodiment is arranged such, and flows into the oil smoke of air intake passage present similar tornado so that deriving from air inlet 5
Form, as shown in Figure 3.Need to be explained, be only the use state reference map of fan assembly shown in Fig. 3, not
There is the range hood structure illustrating other.Exhaust fume collecting hood, for gathering oil smoke the oil smoke pilot flow direction air inlet 5 that will gather.
Furthermore, it is necessary to be explained, motor module proposed by the invention, it uses the work of existing brushless motor
Make principle, the present invention not most part when describing motor module, refer to existing brushless motor technical data.
Below it is only the preferred embodiments of the present invention, some technical characteristic is increased, deletes, revises or replaces and can also obtain
Embodiment to other.As, it is also possible to it is that housing component and impeller all use existing structure；That is, housing component uses spiral case knot
Structure, impeller uses multiple wing type centrifugal impeller.In other words, the ingredient of rotor unit " impeller be configured to operate as " of the present invention
Technical thought, it is also possible to be achieved on the architecture basics of existing fume exhauster thermomechanical components.For another example, the present invention is carried
The motor module gone out, it would however also be possible to employ the operation principle of existing brush motor, certainly, at this moment, the knot of motor module
Structure to be also adjusted correspondingly., it would however also be possible to employ the impeller of other structure, and be not necessarily required to the blade ring of impeller for another example
Around forming air intake passage.
Embodiment 2
The present invention also proposes another kind of smoke exhaust ventilator embodiment 2, and this smoke exhaust ventilator embodiment 2 is in above-mentioned smoke exhaust ventilator embodiment 1
On the basis of improve further and obtain.The main distinction of this smoke exhaust ventilator embodiment 2 and above-mentioned smoke exhaust ventilator embodiment 1 is such as
Under.
This smoke exhaust ventilator embodiment 2 be have employed the fan assembly of a kind of different structure.This smoke exhaust ventilator embodiment 2 is used
Fan assembly, including protective cover the 10, first plate body the 12, second plate body 13, motor module and housing component 4, such as Fig. 5 to 7
Shown in.Needing exist for being explained, for ease of showing dependency structure, the housing component 4 shown in Fig. 7 eliminates this housing component
Wall body at one side of 4, and protective cover 10 is not installed yet.
Motor module includes rotor unit and stator unit.Within rotor unit is arranged at housing component 4, stator unit is set
It is placed in outside housing component 4.First plate body 12 be arranged in parallel with the second plate body 13.Rotor unit includes permanent magnet 7 and impeller.
Permanent magnet 7 is fixed on the second plate body 13.Second plate body 13 is fixed on impeller, and the second plate body 13 is perpendicular to the axle of impeller
The heart.This impeller, produces negative pressure with pump drainage oil smoke for rotation.Visible, the impeller for pump drainage oil smoke of smoke exhaust ventilator, with
Time be used as rotor unit ingredient.This impeller includes 9, the rotating shaft 8 of an axis hole and multiple blade 3, this axis hole 9
At the axle center of this impeller.Rotating shaft 8 is fixed on housing component 4 after axis hole 9, and impeller rotates around this rotating shaft 8.
