Description
Technical field
The present invention relates to a kind of filtration apparatus, more particularly, to a kind of Multistage filtering device for range hood.
Background technology
Range hood can suck substantial amounts of oil smoke when working, the oil smoke of suction easily causes to accumulate and formed big in air passage
The greasy dirt of amount, since the greasy dirt viscosity of formation is larger, it is difficult to discharged from the gas outlet in air passage, thus greasy dirt can not only corrode pipe
Road, shortens the service life of range hood, but also can improve the operation and maintenance cost of range hood.
In order to solve the problems, such as this, currently used way is the air inlet setting lampblack filter in range hood,
Wherein relatively conventional is by the way of two layers of perforate filter plate, such as 200620062667.5 (Granted publications of Patent No. ZL
Number be CN 2937877Y) Chinese utility model patent disclosed in《The oil fume separator of smoke exhaust ventilator》, it include frame and
Fume retainer, upper fume retainer and lower fume retainer interlaced arrangement up and down, air inlet, gas outlet are formed between upper and lower fume retainer
With reflective gas channel, air inlet and gas outlet interlaced arrangement, reflective gas channel connect air inlet and gas outlet.And for example
Disclosed in the Chinese utility model patent of Patent No. ZL 201320201333.1 (Authorization Notice No. is CN 203264452U)
's《Cooking fume filtering plate》, which includes relatively and spaced front and rear panels, foreboard are equipped with multiple first
Opening, the edge of these the first openings are respectively equipped with the front wing panel folded between foreboard and back plate, are provided with back plate multiple
Second opening, the edge of these the second openings are respectively equipped with the rear fender folded between foreboard and back plate, and arbitrary first opens
Mouthful mutually stagger between the adjacent thereto second opening so that front wing panel at first edge of opening and it is adjacent thereto after
It is spaced between wing plate and forms air flue of the connection between first opening and second opening, the both ends of the air flue is formed respectively
Air-flow turning point.
Two filter plates of above-mentioned lampblack filter are staggered to form the gas channel of turnover after all simply simply bending,
Oil smoke only needs simple two deflectings to be flowed out from gas outlet, oil smoke is in gas channel after air inlet enters gas channel
Interior deflecting number is few, i.e. the collision frequency of oil smoke and filter plate is less, further, since smoke barrier and wing plate are tablet, oil smoke
Deflecting can only be carried out along the overbending direction of smoke barrier and wing plate, and cannot be become in the plate face of fume retainer and wing plate
To.In addition, existing filtration apparatus also tend to there is intake it is insufficient the defects of, so as to influence oil filter effect.It can be seen from the above that
The filtering oil smoke effect of above-mentioned lampblack filter need further to improve.
The content of the invention
The technical problems to be solved by the invention are to be directed to above-mentioned state of the art, there is provided a kind of oil smoke is in gas channel
Horizontal and vertical can realize multiple deflecting, collision and the sufficiently large Multistage filtering device for range hood of intake.
Technical solution is used by the present invention solves above-mentioned technical problem：The multistage filtering for being used for range hood fills
Put, include the first oil filtering plate for oil and the second oil filtering plate for oil of point two layers of distribution, it is characterised in that：First oil filtering plate for oil have polylith and
Wherein one layer upper spacing side by side is set, the gap formation primary air inlet between adjacent two pieces of first oil filtering plate for oil, and described second
Oil filtering plate for oil has polylith and spacing side by side is set on another layer, and the gap between adjacent two pieces of second oil filtering plate for oil forms outlet
Mouthful, the primary air inlet is spaced apart with gas outlet, gas channel is formed between the air inlet and adjacent gas outlet, every
At least one set of oil strain unit is provided with a gas channel, every group of oil strain unit is included along primary air inlet and outlet
The oil strain column that the length direction of mouth is spaced apart, is provided with auxilairy air intake, the auxilairy air intake on first oil filtering plate for oil
It is connected by the gas channel with gas outlet.
Preferably, at least two groups of oil strain units, the oil strain unit of adjacent sets are provided with each gas channel
Oil strain column offset one from another on the length direction of primary air inlet and gas outlet, the auxilairy air intake be arranged on adjacent sets filter
Between oily unit, and auxilairy air intake is spaced apart along the length direction of primary air inlet and gas outlet.In this way, oil can be increased
Deflecting and collision frequency of the cigarette in gas channel, are conducive to improve filter effect.
In order to improve filtering oil smoke effect, the oil strain column distinguishes shape towards primary air inlet and the two relative side of gas outlet
Into having convex surface and concave surface, the oil strain unit has two groups, the oil strain column of the oil strain unit of neighbouring primary air inlet convex surface facing
Primary air inlet is simultaneously externally protruded out in primary air inlet, the oil strain column of the oil strain unit of neighbouring gas outlet convex surface facing gas outlet and evagination
In in gas outlet, the auxilairy air intake is arranged on recessed area position corresponding to the oil strain column of neighbouring gas outlet.In this way, oil smoke removes
Horizontal and vertical realization multiple deflecting, collision in air filtration circulation road is outer, can also be in the length side of air inlet and gas outlet
Multiple deflecting, collision are realized upwards, so that oil filter effect is further lifted, and also auxilairy air intake is arranged on the indent of oil strain column
Regional location, is more conducive to deflecting and collision.
Preferably, the section of the oil strain column is arc either U-shaped or V-arrangement.Certainly, the section of oil strain column can also adopt
With other suitable shapes, semicircular arc can be most preferably used.
Oil strain unit can have a variety of mounting structures, it is preferable that the oil strain unit of neighbouring primary air inlet is arranged on the first oil strain
On plate, the oil strain unit of neighbouring gas outlet is arranged on the second oil filtering plate for oil.
Preferably, first oil filtering plate for oil can be separated mutually with the second oil filtering plate for oil, and the oil strain unit is arranged at
On one oil filtering plate for oil or it is arranged on the second oil filtering plate for oil.
In order to make the structure of device more firm, first oil filtering plate for oil, the second oil filtering plate for oil and oil strain unit are integrated into
Type structure.
Compared with prior art, the advantage of the invention is that：This is used for the Multistage filtering device of range hood in air inlet
Be provided with least one set of oil strain unit in gas channel between gas outlet, every group of oil strain unit include along air inlet and
The oil strain column that the length direction of gas outlet is spaced apart, oil smoke can be real in the horizontal and vertical of gas channel in filter process
Now multiple deflecting and collision, also, by setting the auxilairy air intake being connected with gas outlet, increase the air inflow of device,
So as to further lift oil filter effect.
