Description
Technical field
The present invention relates to a kind of multiple field fan blade and its oil smoke separation method.
Background technique
Smoke exhaust ventilator is also known as range hood, is a kind of kitchen appliance for purifying kitchen environment.It is mounted on kitchen health section
Above energy range hood cooking stove, the oil smoke being harmful to the human body generated in the waste and cooking process of cooking stove burning can be taken out rapidly
It walks, discharge is outdoor, reduces pollution, purification air etc..And smoke exhaust ventilator is to the separating effect of oil smoke, fan blade is to play crucial work
With.
Such as Chinese patent CN201320856287.9, includes the center of circle and with the center of circle be it discloses, the fan blade
The radially distributed several strip blades of the heart, one end of the blade are fixedly attached to the center of circle, and the blade is along institute
The cross section for stating the radial direction in the center of circle is equipped at least one bending part.In this patent, since blade is by center in spoke
Penetrate shape distribution, the gap of blade be it is unevenly distributed, especially in fan blade center, density is often higher, when high speed
When rotation, resistance is excessive, and oil smoke cutting not, does not have separating effect well.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of good separating effects, the simple multilayer of structure
Formula fan blade；Meanwhile the present invention also provides a kind of oil smoke separation methods of multiple field fan blade.
In order to achieve the above objectives, the technical solution adopted by the present invention is that: a kind of multiple field fan blade, for installing to rotation axis
To intercept separation oil, aqueous mixtures, wherein the fan blade includes spider and extends multiple blade layers by center plate edge,
Adjacent blades layer has certain interval, and each blade layer includes several strip blades, and each blade all has foldable structure,
Each blade is circumferentially arranged and adjacent blades have certain interval.
In the present solution, by the way that multiple blade layers are arranged, so that the oil smoke entered, under the cutting of multiple blade layers, energy is completely
Ground is separated, and has been compared for the intensive blade of single layer, and the overstocked blade of single layer lacks longitudinal penetration space, so that oil smoke
The resistance passed through becomes larger, and oil smoke can be blocked under blade, and longitudinal layout of the multiple layers of vanes of this programme, in every layer of blade phase
In the case where to reduction, not but not lead to the problem of that resistance is excessive, and the oil smoke of preceding layer blade can be will transmit through, it can be under
One layer of blade further separates, to effectively increase separating effect.
Specifically, the foldable structure of the blade include at least two blades, be the first, second blades, and first,
Second blades are formed by angle towards air intake vent direction, and angle can form interception face, effective interception oil smoke towards air intake vent direction
With particulate matter.
Further, the width of first blades is big compared with the width of the second blades.
The foldable structure of the blade further includes third blades, and three blades are in Y-shaped, and the side of third blades
To towards direction of air outlet, increased third blades can minimize windage while increasing interception face, this is because
It can be by the further cutting of third blades of its behind, without bringing excessive windage across the oil smoke for intercepting face gap.
Further, the width of first blades is big compared with the width of second, third blades.What is be designed in this way is good
It is in the first blades are wider, and downwind, resistance is little, and short the second blades are to arrange for convenience, and third blade is short
It is to facilitate arrangement and reduction frontal resistance.
Further, the blade stagger setting of blade on each blade layer blade layer adjacent thereto, so that through before
The oil smoke of one layer of blade can be blocked by the blade of later layer and carry out cutting, and oil smoke separating effect is more preferable.
Further, the projection of the blade on any blade layer on a neighboring layer can cover between corresponding two blade
Gap, the purpose being designed in this way are so that oil smoke will not improve the separating effect of oil smoke directly through gap.
Further, the diameter range of the spider is 200mm-600mm, in the present solution, using in certain size
Cartridge substitutes the blade that the prior art is directly extended by the center of circle, is avoided that blade near the center of circle is excessively intensive and resistance mistake
Big situation, avoids oil smoke from being excessively gathered in the center point, and blade is made to accumulate too many dirt year in year out, and change into spider it
Afterwards, oil smoke will not collect around in the center of circle, but pass through from blade, in addition, designing in conjunction with multiple layers of vanes of the invention, center
The blade of each layer also can be more sparse near disk, under the premise of guaranteeing blade rotational speed, quantity, avoids resistance excessive, while
Take into account the effect of separation.
Further, the total quantity range of three layers of blade 50-140；The revolving speed of the fan blade is 700-1400r/
min。
Meanwhile the present invention also provides a kind of oil smoke separation methods with the multiple field fan blade, wherein rotation axis is driven
Dynamic fan blade rotation, under suction, oil smoke enters fan blade inner cavity by fan blade bottom end, and oil smoke is by the folding in multiple blade layers
Under the high speed rotation cutting effect of structure, grease is separated by blade end, and air is flowed out by fan blade top, side.
Compared with prior art, the beneficial effects of the present invention are:
The present invention not but not is generated in the case where the opposite reduction of every layer of blade by longitudinal layout of multiple layers of vanes
The excessive problem of resistance, and the oil smoke of preceding layer blade can be will transmit through, it can further be separated in next layer of blade, to have
Effect improves separating effect.

To understand the concrete meaning of above-mentioned term as the case may be.
As shown in Figure 1 to Figure 3, the invention discloses a kind of multiple field fan blades, for installing to rotation axis to intercept separation
Oil, aqueous mixtures, wherein the fan blade includes spider 1 and extends multiple blade layers, the present embodiment by 1 edge of spider
In, blade layer is three layers；Adjacent blades layer has certain interval, and each blade layer includes several strip blades 2, Mei Geye
Piece 2 all has foldable structure, and each blade 2 is circumferentially arranged and adjacent blades 2 have certain interval.
The foldable structure of the blade 2 includes at least two blades 21,22, is the first, second blades 21,22, and
First, second blades 21,22 are formed by angle towards air intake vent direction.
The width of first blades 21 is big compared with the width of the second blades 22.
The foldable structure of the blade 2 further includes third blades 23, and three blades 21,22,23 are in Y-shaped, and the
The direction of three blades 23 is towards direction of air outlet.
The width of first blades 21 is big compared with the width of second, third blades 22,23.
The blade stagger setting of blade on each blade layer blade layer adjacent thereto.
The projection of blade on a neighboring layer on any blade layer can cover the gap between corresponding two blade.
The diameter range of the spider 1 is 200mm-600mm.
The total quantity range of three layer blades 50-140, since the present invention is empty using the stereoscopic arrangement of multiple layers of vanes
Between, each layer of blade quantity can be reduced, wind resistance is effectively reduced, but does not influence the cutting effect to oil smoke.
Further, the revolving speed of the fan blade is 700-1400r/min.When blade rotational speed is excessive, the leaf of high-speed rotation
Sector-meeting makes windage excessive, and oil smoke does not pass through at all, and oil smoke can be back in kitchen, so that isolated substantial effect is very poor.
When being more than 1500r/min such as revolving speed, actually oil smoke does not pass through at all.
