Description
Technical field
The present invention relates to a kind of ducting system with fume purifying function, in smoke exhaust ventilator.
Background technology
Existing lampblack absorber oil cleaner screen used can be divided into two kinds substantially: one is individual layer filter screen, and namely oil smoke only once directly enters air channel through oil network, and this filter screen grease separating degree is low and efficiency is not high; One is also had to be the staggered folded row of multilayer oil network, because oil smoke can enter air channel through 2 ~ 3 collision rift on filter screen, oil separation effect is better, but easily forms strong air agitation noise, and that layer of the finest and closely woven sieve meshes very easily blocks and affect air performance and noise further.
Application number be 201020588928.3 Chinese patent disclose a kind of range hood, it is provided with fairing at the air inlet place of the spiral case of blower fan system.But the effect of this fairing and principle are: effectively can filter the most of vortex entering blower fan, make to enter the air-flow of blower fan evenly, rectification effect is better, and flow quality is better, greatly reduces the aerodynamic noise that blower interior produces, improves cigarette machine performance.Though noise can be reduced, there is no the effect that grease is separated.
Summary of the invention
The object of the invention is to overcome above shortcomings in prior art, and the ducting system with fume purifying function a kind of reasonable in design being provided, improving grease separating degree, reduce noise.
The present invention's adopted technical scheme that solves the problem is: a kind of ducting system with fume purifying function, comprises air channel, motor and impeller; Air channel is provided with air inlet and air outlet; Motor is arranged on air channel; Impeller is connected with the rotating shaft of motor, and its air inlet with air channel and air outlet communicate; It is characterized in that: also comprise deflector; Deflector is fixed on air channel, and is positioned at the air inlet in air channel, is covered by the air inlet in air channel; Deflector comprises fixed head and grid; Fixed head is fixed on air channel; Grid is fixed on fixed head, and grid is sheet; Grid is multiple, forms runner between adjacent two grids; Runner one end is air intake, and the other end is outlet air end, and outlet air end communicates with the air inlet in air channel;
The structure of described grid is at least the one in following three kinds of structures:
(1), adjacent two grids are arranged in parallel, and the axis parallel of the middle section of grid and impeller;
(2), adjacent two grids are arranged in parallel, the α and the axis shape of the middle section of grid and impeller has angle, 0 ° of < α < 60 °;
(3), between adjacent two grids shape has angle β, 0 ° of < β < 60 °; Grid forms divergent shape structure.
Fixed head of the present invention is annular.
The angle of α of the present invention is one in 10 °, 20 °, 30 °, 40 °, 50 °.
The angle of β of the present invention is one in 10 °, 20 °, 30 °, 40 °, 50 °.
The present invention compared with prior art, have the following advantages and effect: produce more polymolecular collision opportunity by the guide functions of grid, and discharge after making soot gas enter air channel in order, greatly improve grease separating degree, meanwhile, the noise of range hood also can reduce further.

Detailed description of the invention
Below in conjunction with accompanying drawing, also by embodiment, the present invention is described in further detail, and following examples are explanation of the invention and the present invention is not limited to following examples.
See Fig. 1 ~ Fig. 8, the embodiment of the present invention comprises air channel 1, motor 2, impeller 3 and deflector 4.
Air channel 1 is provided with air inlet and air outlet.
Motor 2 is arranged on air channel 1.
Impeller 3 is connected with the rotating shaft of motor 2, and its air inlet with air channel 1 and air outlet communicate.
Deflector 4 comprises fixed head 5 and grid 6; Deflector 4 is fixed on air channel 1, and is positioned at the air inlet in air channel 1, is covered by the air inlet in air channel 1.
Fixed head 5 is annular, is fixed on air channel 1.
Grid 6 is fixed on fixed head 5.Grid 6 is multiple, forms runner 7 between adjacent two grids 6; Runner 7 one end is air intake, for inspiration soot gas; Runner 7 other end is outlet air end, and outlet air end communicates with the air inlet in air channel 1.Grid 6 is sheet, produces the effect of water conservancy diversion.
Motor 2 impeller 3 forms negative pressure after rotating, and the air intake of runner 7 accepts the soot gas flowing because negative pressure produces, and produce molecular collision and cutting out partial smoke particle through grid 6 when soot gas flows in runner 7, remaining gas is discharged through air channel 1.
Embodiment 1: adjacent two grids 6 are in arranged in parallel, and the axis parallel of the middle section of grid 6 and impeller 3.Soot gas flows through in the process of runner 7 due to suction function, and Large stone soot particles can depend on grid 6 on travel path, thus only has fraction oil smoke to enter impeller 3 and air channel 1.Along with the oil smoke on grid 6 gathers, finally because Action of Gravity Field landing is to the oil collector sump tank in air channel 1.
Embodiment 2: adjacent two grids 6 in arranged in parallel, the α and the axis shape of the middle section of grid 6 and impeller 3 has angle, 0 ° of < α < 60 °.On the basis of embodiment 1, increase the air-flow angle of attack, increase soot particles collision dynamics and probability, improve grease separating degree further.The angle of α is one in 10 °, 20 °, 30 °, 40 °, 50 °.
Embodiment 3: between adjacent two grids 6, shape has angle β, 0 ° of < β < 60 °, grid 6 forms divergent shape structure.The divergent shape structure of grid 6, adapts to the gas field feature that lower flow passage blast is large, upper flow passage blast is little, and air inlet is more even, makes the adsorbance of soot particles on grid 6 average.The angle of β is one in 10 °, 20 °, 30 °, 40 °, 50 °.
In addition, it should be noted that, the specific embodiment described in this description, the shape, institute's title of being named etc. of its parts and components can be different, and the above content described in this description is only to structure example of the present invention explanation.
