Stream, or blow into ejection cavity 34 at a high speed and high pressure air-flow.
Reference picture 1, bearing 1 can be formed generally as the receiving space opened wide in rectangular parallelepiped structure, bearing 1 with top
12, fan assembly 2 is arranged in the receiving space 12 of bearing 1.Specifically, import 11 can be arranged on the side wall of bearing 1, entered
Mouth 11 can be formed as cell structure, but not limited to this.Thus, it is possible to be carried out by grid to entering the air in blower fan 2
Filter, reduce into the impurity in blower fan 2, it is to avoid the impurity in air causes to damage to blower fan 2, improves the property of blower fan 2
Can, extend the service life of blower fan 2.
Air intake assembly 4 is located on bearing 1, and air intake assembly 4 has at least one oil smoke entrance 41, and the insertion of oil smoke entrance 41 is entered
The wall body of wind component 4.Wherein, oil smoke entrance 41 can be one or more.For example, in the example of fig. 1, oil smoke entrance 41
To be multiple, multiple oil smoke entrances 41 are distributed in air intake assembly 4.Alternatively, multiple oil smoke entrances 41 can equably between
Every being distributed on the wall of air intake assembly 4, specifically, multiple oil smoke entrances 41 scatter setting on the wall of air intake assembly 4.By
This, can increase the aspiration ranges of range hood 100, it is ensured that the oil smoke of all directions is sucked into air intake assembly 4, oil suction is improved
The oil suction smoke performance of cigarette machine 100.Alternatively, oil smoke entrance 41 can be formed as circular, oval, polygon or irregular component
Shape etc..

0.6R、R1=0.8R etc..Thus, it is easy to the air-flow in air intake assembly 4 to flow into injection component 3, that is, is easy in the first oil smoke chamber 42
Air-flow flow into the second oil smoke chamber 35, it is and simple in construction, it is easy to process.
Alternatively, air stream outlet 346 is formed as circular, and the radius of air stream outlet 346 is R2, R2Meet：0.5R1≤R2≤
0.75R1.For example, the radius R of air stream outlet 3462It can meet：R2=0.5R, R1=0.6R, R1=0.75R etc..Thus, it is possible to
Negative pressuren zone is formed at air stream outlet 346, it is ensured that the pressure difference inside and outside range hood 100, consequently facilitating outside suction range hood 100
The air in portion, improves the oil suction smoke performance of range hood 100.
According to some embodiments of the present invention, the width of eductor outlet 342 is d, and d is met：0.5mm≤d≤2.5mm.Its
Concrete numerical value can be according to the The concrete specification model adjusted design of range hood 100, and the present invention is not especially limited to this.Example
Such as, the width d of eductor outlet 342 can be met：D=0.5mm, d=0.8mm, d=1mm, d=1.5mm, d=2mm or d=
2.5mm wait.Thus, it is possible to reduce the area of eductor outlet 342, the flow velocity of air-flow at increase eductor outlet 342, so as to protect
Demonstrate,prove the air viscosity frictional force at eductor outlet 342 so that negative pressuren zone can be formed at air stream outlet 346, fume-exhausting will be sucked
Air outside machine 100, improves the oil suction smoke performance of range hood 100.
Specifically, air stream outlet 346 is relative with air flow inlet 345.For example, air stream outlet 346 can be with air flow inlet 345
It is just right.Reference picture 2, air flow inlet 345 can form the left end in injection component 3, and air stream outlet 346 can be formed in injection group
The right-hand member of part 3, the central axis of air stream outlet 346 is overlapped with the central axis of air stream outlet 346.Thus, it is possible to shorten air-flow
Flow path, reduce air current flow energy consumption, so as to reduce the overall energy consumption of range hood 100.
Alternatively, the air-out direction of air stream outlet 346 is overlapped with horizontal direction, or relatively horizontal orientation is tilted upward.
Thus, it is possible to which the air-flow for avoiding air stream outlet 346 from discharging is impacted to dining area or the personnel of having dinner, the personnel of having dinner are improved
Comfortableness.
At least one according to some embodiments of the present invention, in the import 11 of the air inlet 21 and bearing 1 of fan assembly 2
It is provided with the 3rd filtration members (not shown).Specifically, the 3rd filtering can be set only at the air inlet 21 of fan assembly 2
Part, can also set the 3rd filtration members only in the import 11 of bearing 1, can also fan assembly 2 air inlet 21 and bearing 1
Import 11 on be respectively provided with the 3rd filtration members.Alternatively, the 3rd filtration members can be screen pack etc..Thus, it is possible to pass through the 3rd
Filtration members are filtered to entering the air in fan assembly 2, reduce the impurity in entrance fan assembly 2, it is to avoid air
In impurity to fan assembly 2 cause damage, improve the performance of fan assembly 2, extend the service life of fan assembly 2.
