In the present embodiment, ensureing mounting leg 242 itself with sufficient intensity to support the premise of the quality of motor 230
Under, on the direction far from rack body 241, the width of above-mentioned mounting leg 242 is preferably in tapered setting.It is appreciated that
That, due to the centrifugation characteristic of centrifugal wind wheel 220 itself, the centrifugal force closer to the position of its fan blade is bigger, intake also compared with
Greatly, at this point, the width of the mounting leg 242 at the blade of centrifugal wind wheel 220 is smaller, air is also easier to by installation branch
Foot 242 flows to centrifugal wind wheel 220, the air intake resistance smaller of mounting leg 242, and then to match centrifugal wind wheel 220 in the position
Intake.Meanwhile the width of the mounting leg 242 close to rack body 241 is bigger, mounting leg 242 and rack body 241
Joint face it is bigger, and then also can guarantee between mounting leg 242 and rack body 241 have good bonding strength, carry
The bearing capacity of high electric machine support 240.Certainly, in some other embodiments, the width of above-mentioned mounting leg 242 can also
It is invariable, no longer specific narration herein.
In order to improve the structural strength of mounting leg 242 and 241 junction of rack body, in the present embodiment, mounting leg
242 are additionally provided with reinforcing rib structure with the junction of rack body 241 so that and the overall construction intensity of electric machine support 240 enhances, with
Ensure that electric machine support 240 has preferable load-carrying properties.
It is worth noting that when centrifugal wind wheel 220 rotates, fraction then forms edge by the drive of centrifugal wind wheel 220
The swirling eddy of the circumferential movement of centrifugal wind wheel 220, the swirling eddy, can be by the peaces of electric machine support 240 in flow process
The influence of stabilizer blade 242 is filled, the flow direction of swirling eddy and the plate face of mounting leg 242 are mutually perpendicular at this time, and then are easy to lead
Cause windage of swirling eddy when by mounting leg 242 larger；Meanwhile swirling eddy, when by mounting leg 242, meeting exists
The leeward side of mounting leg 242 forms vortex, and then it is unstable to cause the air-flow in spiral case 210 to flow, and causes 1 wind of range hood
The defects of amount declines and noise aggravates.
In order to reduce influence of the mounting leg 242 to above-mentioned swirling eddy, with reference to Fig. 9 to Figure 12, in this electric machine support 240

To 20 millimeters.At this point, the ventilation hole 2421 is preferably slotted hole, so that the area of ventilation hole 2421 is relatively large, so that
Air-flow flow through it is more smooth when ventilation hole 2421.
It is emphasized that since range hood 1 uses centrifugal wind wheel 220, centrifugal wind wheel 220 is in its air inlet 2101
Air-flow predominantly axially flows, and after air-flow enters in centrifugal wind wheel 220, air-flow is gradually converted into the diameter along centrifugal wind wheel 220
To flowing, at this point, for electric machine support 240, one end of mounting leg 242 is close to the import of centrifugal wind wheel 220, the other end
Then close to the neighboring of centrifugal wind wheel 220, there is also differences for airflow direction of the air-flow at the different location of mounting leg 242
It is different.In order to which the air-flow ensured in centrifugal wind wheel 220 swimmingly can be changed into Radial Flow by axial flow, in the present embodiment, on
It states ventilation hole 2421 close to rack body 241 to be arranged, so that the air-flow of centrifugal wind wheel 220 flowed in an axial direction can be by logical
Air holes 2421 flows, and then reduces the flow resistance of above-mentioned swirling eddy, improves the air flow rate of ventilation hole 2421 so that ventilation
Hole 2421 to the crushing effect of vortex more preferably, to further decrease the noise of wind turbine, improve the air quantity of range hood 1.
Referring to Fig.1 3 to Figure 20, in the 3rd embodiment of this electric machine support 240, mounting leg 242 is perpendicular to described
Projected length direction and the radial direction of rack body 241 in the plane of the axis of rack body 241 are inclined to set, and pacify
The inclined direction for filling the projection of stabilizer blade 242 is consistent with the rotation direction of motor.It is understood that compared with a upper embodiment,
It is differed only in：The mounting leg 242 of the electric machine support 240 is arranged in relative tilt, and turn of inclined direction and motor
To consistent.In this way, when motor driving centrifugal wind wheel 220 rotates, swirling eddy is formed by more easily by mounting leg 242
Ventilation hole 2421, thereby reduce gas-flow resistance when swirling eddy flows through mounting leg 242, reduce mounting leg 242
Leeward side generates the probability of vortex, contributes to the noise for further decreasing wind turbine and improves the air quantity of range hood 1.In addition, by
In mounting leg 242 in relative tilt be arranged, in addition can to enter fan assembly 20 in air-flow formation prewhirl, increase air-flow into
Gas inclination angle is conducive to promote intake efficiency and then improves the air quantity of range hood 1.
Wherein, projected length direction of the mounting leg 242 in the plane perpendicular to the axis of the rack body 241 with
Angle α between the radial direction of rack body 241 is ranging from：0 ° of 90 ° of ＜ α ＜；Wherein, in order to make to enter blower fan group
The air inlet inclination angle of air-flow in part 20 is relatively large, to be more conducive to promote intake efficiency, in the present embodiment, the range of the angle α
It is further：35 °≤α≤55 °, when α is preferably 45 °, the intake efficiency of fan assembly 20, and then can be notable into reaching best
Improve the air quantity of range hood 1.
Certainly, in the first embodiment of electric machine support 240, although ventilation hole 2421 is not arranged for mounting leg 242,
Also it can weaken influence of the mounting leg 242 to swirling eddy by the way that mounting leg 242 is obliquely installed mode.
With reference to Figure 21 to Figure 24, in the fourth embodiment of electric machine support 240, mounting leg 242 is perpendicular to holder sheet
