Abstract
The utility model discloses a kind of range hood, including the interior casing for setting blower fan, it is characterised in that：Flatly screens is provided with the casing, the screens is plate-like and offers multiple mesh, the mesh is in uniform or is non-uniformly distributed.By screens being arranged in runner, the air-flow for entering into blower fan can be split, eliminate larger whirlpool in oil smoke air-flow, so as to reduce the purpose of noise；By the mesh non-uniform Distribution of screens is caused, better adapt to adapt to oil smoke flow field, improve noise reduction efficacy；By arranging certain percent opening so that the fluid to entering blower fan is preferably split, while reducing the windage that screens itself is produced to greatest extent.
Description
Technical field
The utility model is related to kitchen appliance, especially a kind of range hood.
Background technology
Range hood has become one of indispensable machine for kitchen use equipment in Modern Family, and usual range hood includes top
Suction and side-suction type, and the range hood of top suction type due to clean and tidy light and handy, take up room little the advantages of, and have more and more extensive
Application.Top-sucking kitchen ventilator generally includes exhaust fume collecting hood, the blower housing being located on exhaust fume collecting hood, is provided with snail in blower housing
The motor of shell, impeller and driving impeller.
The range hood of conventional top suction type, a kind of suction as disclosed in the Chinese patent of Application No. 201410704669.9
Lampblack absorber, including the exhaust fume collecting hood with inlet scoop, is arranged on the wind cabinet on exhaust fume collecting hood top, is arranged on the wind with spiral case in wind cabinet
Machine, by the effect of blower fan, forms negative pressure so as to outside oil smoke is sucked cabinet wind cabinet while the gas in wind cabinet is discharged
Interior, realize the purpose of fume-exhausting.
As people increasingly focus on quality of life, the noise problem of range hood is increasingly taken seriously.Noise
Size be to evaluate an important indicator of range hood quality, and noise and air quantity are two conflicting technical indicators, both
Air quantity to be kept, control noise is a very big technical barrier again.
The noise source of lampblack absorber is substantially from two parts of rotational noise and turbulence noise of draught fan impeller.Drop at present
The noise of low range hood mainly or by the way of passive noise reduction, by aerodynamic mode to centrifugal blower, snail
Shell is optimized, but this smoke evacuation air quantity for often leading to range hood reduces, and noise reduction is not fairly obvious.As changing
Enter, also have by the way of active noise reduction in prior art.As the turbulence noise of range hood directly results from centrifugal blower,
Which is mainly derived from the air intake at air inlet of centrifugal fan, if the oil smoke flow in the oil smoke passage before air inlet of centrifugal fan
Dynamic disorderly and unsystematic, then can increase the condition of turbulent flow generation, thus cause the noise of range hood larger.
Utility model content
Technical problem to be solved in the utility model is the problem existed for above-mentioned prior art, provides a kind of effective
Reduce the range hood of noise.
The utility model solves the technical scheme that adopted of above-mentioned technical problem：A kind of range hood, sets wind including interior
The casing of machine, it is characterised in that：Flatly screens is provided with the casing, the screens is plate-like and offers many
Individual mesh, the mesh are in uniform or are non-uniformly distributed.
Preferably, in order to the soot gas flow field in casing is better adapted to, there is on the screens at least oneth area
Domain, in the region, the density of the mesh is more than the density of the area peripheral edge.
Preferably, the mesh is square hole, circular hole, diamond hole, slotted eye or regular polygon hole, it would however also be possible to employ other
Shape.
Preferably, in order to preferably eliminate whirlpool, the fluid to entering blower fan is preferably split, while to greatest extent
Reduce the windage that screens itself is produced, the percent opening of the screens is 30%～85%.
Further, being connected for ease of screens and casing, the left and right sides of the screens has flange.
Compared with prior art, the utility model has the advantage of：By arranging screens in runner, can be to entering
Air-flow to blower fan is split, and eliminates larger whirlpool in oil smoke air-flow, so as to reduce the purpose of noise；By making
The mesh non-uniform Distribution of screens is obtained, is better adapted to adapt to oil smoke flow field, improves noise reduction efficacy；Certain by arranging
Percent opening so that the fluid to entering blower fan is preferably split, while reduce what screens itself was produced to greatest extent
Windage.
Description of the drawings
Fig. 1 is the schematic diagram of range hood of the present utility model；
Fig. 2 is the schematic diagram of screens one embodiment of range hood of the present utility model；
Fig. 3 is the schematic diagram of second embodiment of screens of range hood of the present utility model；
Fig. 4 is the schematic diagram of the 3rd embodiment of screens of range hood of the present utility model.
Specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
Embodiment one
Referring to Fig. 1, a kind of range hood, including exhaust fume collecting hood 1, the casing 2 being arranged on above exhaust fume collecting hood 1, arrange in casing 2
There is blower fan 3.Air inlet is offered on exhaust fume collecting hood 1, and thus, oil smoke can be aspirated through air inlet and enter into by the blower fan 3 in casing 2
Common flue is discharged into after casing 2.
Screens 4 is provided with casing 2, screens 4 is arranged horizontally in casing 2, and screens 4 is plate-like, opens thereon
Mesh 41 is provided with, by screens 4 is arranged, the air-flow for entering into blower fan 3 can be split, eliminate in oil smoke air-flow relatively
Big whirlpool, so as to reduce the purpose of noise.
Referring to Fig. 2, mesh 41 can be square hole, and be evenly distributed on screens 4, it is preferred that percent opening is
30%～85%, thus whirlpool is preferably eliminated, the fluid to entering blower fan 3 is preferably split, while to greatest extent
Reduce the windage that screens 4 is produced itself.
The left and right sides of screens 4 has flange 42, it is possible thereby to be used for being connected with 2 inner side of casing.In this enforcement
In example, the edge of screens 4 bends downwards and forms above-mentioned flange 42.
Embodiment two
Difference with above-described embodiment one is that in the present embodiment, mesh 41 is in non-uniform Distribution on screens 4.
This is that the raw whirlpool of cooking fume miscarriage is uneven, for the part that whirlpool is more concentrated, on screens 4 due in casing 2
With at least one region, in the region, thus the density of mesh 41 can be better adapted to more than the density of the area peripheral edge
Oil smoke flow field, improves noise reduction efficacy.
Embodiment three
Difference with above-described embodiment one is that in the present embodiment, mesh 41 ' is circle.
Alternatively, mesh can also be diamond hole, slotted eye, regular polygon hole etc..
