Fume extractor 10 according to the ... of the embodiment of the present invention is described in detail below with reference to Fig. 1-Figure 11.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 and Figure 11, fume extractor 10 according to the ... of the embodiment of the present invention
Including：Fan assembly 1 and exhaust fume collecting hood 2, fan assembly 1 may include：Wind turbine 11 and Fan casing 12, wind turbine 11 are set to Fan casing
In 12, wind turbine 11 is vertically placed, and the modes of emplacement of wind turbine 11 is different from the modes of emplacement of conventional fan as a result, conventional fan
Modes of emplacement is laterally disposed, that is to say, that the axial direction of wind turbine 11 of the invention is front-rear direction, and the axial direction of conventional fan is upper
Lower direction, so on the one hand setting can improve the air flowing inside fume extractor 10 as a result, on the other hand can shorten row
The depth of cigarette device 10 in the longitudinal direction is intended to small-sized and efficient direction hair so as to be conducive to fume extractor 10
Exhibition.
Fan casing 12 only has the first smoke inlet 13 towards opened backward, and in other words, the rear surface of Fan casing 12 is arranged
There is the first smoke inlet 13, other smoke inlets are not correspondingly arranged in the other surfaces of Fan casing 12.The fume extractor of the present invention
First smoke inlet 13 is only arranged in fan assembly 1, and the entirety that can promote fume extractor 10 in a limited space in this way holds together cigarette
Effect.
Exhaust fume collecting hood 2 is arranged in the lower section of fan assembly 1, and exhaust fume collecting hood 2 has the second smoke inlet 21 and the second outlet flue 22, the
Downward, the second outlet flue 22 is connected to two smoke inlets 21 with the first smoke inlet 13, wherein exhaust fume collecting hood 2 may include：Deflector
23, deflector 23 is located at the top of the second smoke inlet 21, and deflector 23 tilts upward extension in direction from front to back and sets
It sets, deflector 23 can play guide functions.
Wherein, the surface structure of deflector 23 can be one kind in plane, curved surface and cambered surface, can also be the above geometry
The combination in face.
Specifically, as shown in figure 8, when fume extractor 10 works, after oil smoke moves at the second smoke inlet 21, second
At smoke inlet 21 under the action of suction airstream, oil smoke can be entered by the second smoke inlet 21 in exhaust fume collecting hood 2, then pass through water conservancy diversion
The effect of plate 23, deflector 23 can be the second outlet flues of cooking smoke guiding 22, and such oil smoke, which will continue to move upwards, enters first
Smoke inlet 13, when oil smoke moves to the inlet of wind turbine 11, under the action of wind turbine 11, oil smoke can be via 6 row of flue outlet
Go out fume extractor 10, the smoke evacuation work of fume extractor 10 may be implemented.
During above-mentioned oil smoke flowing, deflector 23 can guide oil smoke in the internal gas flow runner of fume extractor 10
Interior flowing will not cause locally to generate vortex in fume extractor 10, can reduce aerodynamic drag loss, can improve fume extractor
10 smoking efficiency can also reduce noise when fume extractor 10 works, so as to promote user satisfaction.
In addition, can also make regional gas stream nowed forming near except the second smoke inlet 21 more smooth, Ke Yikuo
Hold together cigarette range greatly, so as to reduce the air-flow fluid resistance loss other than fume extractor 10, and then may be implemented more preferably to inhale
Oil smoke effect,.
Coordinated as a result, by fan assembly 1 and exhaust fume collecting hood 2, the aerodynamic drag loss of fume extractor 10 can be reduced, it can be with
The smoking efficiency for improving fume extractor 10 can also reduce noise when fume extractor 10 works.With traditional fume extractor phase
Than under identical air quantity, the effect of zero leakage cigarette may be implemented in the present invention, which is more than or equal to
13.8m3When/min, the oil smoke in kitchen can be absorbed completely.
Optionally, the angle between the preceding lower end and horizontal plane of deflector 23 is a, and a meets：90 ° of 35 °≤a ＜, need
Bright, the angle constituted between deflector 23 and horizontal plane can be adjusted within different angular ranges, be met above-mentioned
The deflector 23 of angular range can preferably guide the oil smoke in exhaust fume collecting hood 2 to move, and can be further reduced fume extractor
The generation being vortexed in 10, can effectively reduce the noise of fume extractor 10.
Further, a can meet：35 °≤a≤60 °, it is to be understood that the preceding lower end of deflector 23 and horizontal plane
Between the adjustable range of angle can be between 35 ° to 60 °, oil smoke can preferably be imported fume extractor 10 by such setting
It is interior, it can be also better protected from the generation of local eddy currents, so as to preferably reduce aerodynamic drag loss.
Specifically, as shown in figure 3, Fan casing 12 may include：The rear end of lower plate 14, lower plate 14 is only supported with deflector 23,
And lower plate 14 supports rear upper end preset distance of the place apart from deflector 23 with stopping for deflector 23, and such setting can make lower plate 14
It is only against at deflector 23, lower plate 14 can play a supporting role to deflector 23, when fume extractor 10 works, can make to lead
The position of flowing plate 23 is more firm, can reduce the vibration of deflector 23, works so as to further decrease fume extractor 10
When noise.
Optionally, as shown in Fig. 2, projection in the horizontal plane, before the front end of existing exhaust fume collecting hood has been more than Fan casing
End, and the front end of exhaust fume collecting hood of the present invention 2 is no more than the front end of Fan casing 12, such setting can make the depth of fume extractor 10 contract
It is short, volume shared by fume extractor 10 can be reduced, so as to reduce the cooking space that fume extractor 10 occupies.
