Abstract
The invention discloses a double-blade wind wheel which comprises a bottom plate and a fixed plate. The double-blade wind wheel further comprises a plurality of inner-layer blades and a plurality of outer-layer blades, wherein the inner-layer blades and the outer-layer blades are arranged between the bottom plate and the fixed plate. The double-blade wind wheel has the advantages that the structure is simple, oil and smoke exhaust efficiency is high, an existing wind wheel structure can be fully utilized for improvement, and high adaptability is achieved.
Description
Technical field
The present invention relates to a kind of kitchen ventilator accessory, especially relate to a kind of wind wheel structure.
Background technique
The wind wheel of kitchen ventilator common at present comprises base plate, multiple fan blade and fixed plate, and wherein base plate is provided with the attachment hole of fixing fan shaft, and one end of fan blade is around being arranged on the edge of base plate, and the other end is fixed by fixed plate.During work, blower fan drives wind wheel to rotate, and suck oil smoke from fixing part side, and thrown away from the side of wind wheel is centrifugal by fan blade gap, oil smoke can produce baffling in wind wheel, and the thickness of whole blower fan can correspondingly reduce.But this wind wheel relies on centrifugal force to be discharged by soot gas completely, and its rate of air sucked in required is limited to the power of blower fan, adaptability is not very strong.
Summary of the invention
The object of this invention is to provide two fan blade wind wheels that a kind of rate of air sucked in required is large.
Technical solution of the present invention is: a kind of two fan blade wind wheel, comprises base plate and fixed plate, also comprises and is arranged on several internal layer fan blades between described base plate and fixed plate and several outer fan blades.
Double-deck fan blade is set between base plate and fixed plate, when wind wheel rotates, suck gas first through internal layer fan blade is centrifugal throw away after, enter outer fan blade to be again centrifuged and to throw away, the corresponding increase of exhaust pressure, reduces the pressure of suction port, thus more cooking fume is inhaled into, when not increasing power of fan, significantly improve its rate of air sucked in required.
Described internal layer fan blade and outer fan blade horizontal section curved.Be conducive to air-flow to throw away from fan blade is centrifugal, reduce the vapour lock of fan blade, improve rate of air sucked in required further.
The outer edge of described internal layer fan blade is between adjacent two described outer fan blade inside edges.More easily directly enter outer fan blade by the centrifugal air-flow thrown away of internal layer fan blade, decrease gas-flow resistance, improve exhaust efficiency.
The quantity of described internal layer fan blade is not more than the quantity of described outer fan blade.Making full use of the structure space of existing wind wheel, when ensureing constancy of volume, promoting air displacement.
Described base plate is provided with exhaust port.The convenient cooking fume sucking base plate dorsal part, improves the effect of cooking-fume discharging.
Advantage of the present invention is: structure is simple, and cooking-fume discharging efficiency is high, and can make full use of existing wind wheel structure and improve, adaptability is extensive.

Embodiment
Embodiment:
Consult Fig. 1-2, a kind of two fan blade wind wheel, several internal layer fan blades 6 and several outer fan blades 5 of comprising base plate 1 and fixed plate 2 and being arranged between base plate 1 and fixed plate 2.Base plate 1 is provided with attachment hole 3 and the exhaust port 4 of fixing fan shaft.The quantity of internal layer fan blade 6 is 58, and the quantity of outer fan blade 5 is 64.The horizontal section of each internal layer fan blade 6 and each outer fan blade 5 is curved, and the outer edge of each internal layer fan blade 6 is between the inside edge of adjacent two outer fan blades 6.The quantity of internal layer fan blade 6 and outer fan blade 5 also can be odd number.
Between base plate 1 and fixed plate 2, double-deck fan blade is set, when wind wheel rotates, suck gas first through internal layer fan blade 6 is centrifugal throw away after, enter outer fan blade 5 to be again centrifuged and to throw away, the corresponding increase of exhaust pressure, reduces the pressure of suction port, thus more cooking fume is inhaled into, when not increasing power of fan, significantly improve its rate of air sucked in required.Because the cross section of internal layer fan blade 6 is curved, and its outer edge is positioned in the middle of the inside edge of adjacent two outer fan blades 5, and the air-flow be inhaled into is dumped in outer fan blade 5 more easily by internal layer fan blade 6, is centrifuged acceleration further.By twice acceleration of internal layer fan blade 6 and outer fan blade 5, the airspeed of discharging from wind wheel obviously increases, thus reduces the negative pressure of its suction side, and more oil smoke can be drawn into.Through measuring and calculating, be 22m by the air displacement of the wind wheel of the present embodiment
3/ hour, far above the 12-13m of existing same size wind wheel
3/ hour air displacement, bleed effect promoting clearly.
Above-listed detailed description is illustrating for one of the present invention possible embodiments, and this embodiment is also not used to limit the scope of the claims of the present invention, and the equivalence that all the present invention of disengaging do is implemented or changed, and all should be contained in the scope of the claims of this case.
Claims (5)
