Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
Referring to Fig. 1~Fig. 5, a kind of current collector, for centrifugal blower, the centrifugal blower is mainly used in range hood.
Centrifugal blower includes spiral case 1, the impeller 2 and current collector 3 being arranged in spiral case 1, and spiral case 1 has at air outlet
There is a snail tongue 11, current collector 3 is arranged on the air inlet of the front side of spiral case 1 and coaxial with impeller 2.When impeller 2 rotates, in spiral case 1
Air be discharged to by being arranged on the outlet housing 4 at the air outlet of spiral case 1 outside spiral case 1, be internally formed negative pressure in spiral case 1, oil
After cigarette is entered in the presence of negative pressure by current collector 3 in spiral case 1, common flue or discharge are discharged in the presence of impeller 2
It is outdoor.
Current collector 3 includes wind-guiding face 31 and stationary plane 32, wherein stationary plane 32 just facing to cooking fume stream, stationary plane 32
The back side then towards spiral case 1.Stationary plane 32 in annular shape, wind-guiding face 31 extend certain distance from the radially inner side of stationary plane 32 and
Formed.Wind-guiding face 31 includes the radial direction wind-guiding face 311 for diametrically extending certain distance from the radially inner side of stationary plane 32, and
Extend the axial wind-guiding face 312 of certain distance, the He of radial direction wind-guiding face 311 in the axial direction from the radially inner side of radial direction wind-guiding face 311
Rounding off between axial wind-guiding face 312.Axial wind-guiding face 312 stationary plane 32 reverse side, i.e., when current collector 3 is installed to
After on spiral case 1, axial wind-guiding face 312 is to extend towards impeller 2.Wind-guiding face 31 and stationary plane 32 are integrated.Among wind-guiding face 31
Be formed as air inlet 33, oil smoke air-flow can be entered inside spiral case 1 by air inlet 33.
Radial direction wind-guiding face 311 can be in certain inclination, such as from the radially inner side of stationary plane 32 to centre gradually towards away from leaf
The direction of wheel 2 tilts.Axial wind-guiding face 312 is from the radially inner side of radial direction wind-guiding face 311 gradually to intermediate, inclined so as to forming circle
Taper.Diameter at axial axial end of the wind-guiding face 312 away from radial direction wind-guiding face 311 is designated as the diameter D of air inlet 33, axially
Angle between wind-guiding face 312 and the axis X of current collector 3 is β.To cause wind-guiding face 31 to have preferable water conservancy diversion effect, β's takes
Value scope is preferably 2 °<β<20°.
Axial wind-guiding face 312 has the end 3122 of first end 3121 and second in the circumferential, and axial wind-guiding face 312 is in first end
3121 and second be in respectively between end 3122 straight the first wind-guiding section 3123 and circular arc the second wind-guiding section 3124, first leads
The wind-guiding section 3124 of wind section 3123 and second forms the ring-type of closing.Thus air inlet 33 is in asymmetric non-rotating shape.Wherein
The action of two wind-guiding sections 3124 is H, and the relation between action H and the diameter D of air inlet 33 is 0.8<H/D<1, thus it can protect
The enough incoming air areas of air inlet 33 are demonstrate,proved, and can ensures to increase the flowing space of enough oil smoke air-flows.
Referring to Fig. 6~Fig. 9, when current collector 3 is installed on spiral case 1, the center line L1 and spiral case of the first wind-guiding section 3123
Angle between vertical line L 2 (when centrifugal blower erects dress, extending in vertical direction row and by the line of the air inlet axis of spiral case 1)
For α, α span is preferably -30 °<α<30 ° (when α is 0, i.e. L1 and L2 are overlapped, referring to Fig. 6).So that current collector
3 part of the first wind-guiding section 3123 is corresponding with the snail tongue 11 of spiral case 1, i.e., is set close to snail tongue 11.
When centrifugal blower works, its rotational noise and eddy current crack be mainly derived from oil smoke air-flow and snail tongue 11 impact,
Separation, cooking fume miscarry raw pressure fluctuation so as to produce noise；After current collector 3 is arranged as above, due to the first straight wind-guiding
The presence of section 3123 (air inlet equivalent to current collector is crosscut) so that air inlet is reduced at snail tongue 11, while at snail tongue 11
The flowing space increases, and so reduces the oil smoke air-flow that participation is badly flowed at snail tongue 11, while the space increased is cooking fume
The impact of stream adds cushion space, asymmetrically shape can effective shielded sound propagation so that the stream of gas at snail tongue 11
Dynamic impact amplitude reduces, and the pulsation of volute outlet gas pressure is reduced, so as to reduce fan noise.
