Description
Technical field
The present invention relates to a kind of filter, especially a kind of filter for range hood.
Background technology
With the improvement of living standard, the raising to life quality requirements, range hood is cooked as exhaustion in family kitchen
The important electrical equipment of oil smoke produced by timing, and be widely used in each family.The subject matter that presently, there are is,
Range hood work when, the oil smoke through air channel easily accumulates substantial amounts of greasy dirt in air channel, due to formed greasy dirt viscosity compared with
Greatly, it is difficult to discharge from the air outlet in air channel, corrosion of the greasy dirt to pipeline is caused, reduces the service life of range hood, while
Improve the operation and maintenance cost of range hood, and another part then direct outer row, in oil smoke containing a large amount of carcinogenic substances and
Material of the particle more than pm2.5 produces considerable influence to environment.
In order to solve this problem, at present conventional way is the air inlet setting lampblack filter in range hood,
And more conventional in lampblack filter is then by the way of two-layer filter, to be subtracted by colliding with soot gas
The filtration to lampblack absorber grease is realized in the effects such as speed, condensation.As disclosed in the Chinese patent of Application No. 200620062667.5
A kind of oil fume separator of smoke exhaust ventilator, including framework and fume retainer, upper fume retainer and lower fume retainer up and down interlock phase
To arrangement, air inlet, gas outlet and reflective gas channel are constituted between upper and lower fume retainer, air inlet and gas outlet interlock cloth
Put, reflective gas channel connects air inlet and gas outlet；And for example the Chinese patent of Application No. 201320201333.1 is disclosed
A kind of cooking fume filtering plate, including relative and spaced front and rear panels, header board is provided with multiple first openings, and first opens
The edge of mouth is respectively equipped with the front wing panel folded between front and rear panels, and multiple second openings are provided with back plate, and second opens
Mouthful edge be respectively equipped with the rear fender folded between front and rear panels, arbitrary first opening and second opening of being adjacent
Mutually stagger so as to be spaced and formed connection between the front wing panel and its adjacent rear fender at the first edge of opening between mouthful
Air flue between the first opening and the second opening, the two ends of air flue form respectively air-flow turning point.
Above-mentioned lampblack filter, two filter is staggered to form the air-flow of turnover and leads to after all simply simply bending
Road, oil smoke is entered after gas channel from air inlet, and only needing simple two to become can flow out backward from gas outlet, and oil smoke is in air-flow
Break-in number of times is few in passage, i.e. oil smoke is less with the collision frequency of filter, and thus filter can not preferably play expected
Condensation to oil smoke, the particulate matter in oil smoke still has major part to discharge gas channel with flue gas, adsorbs in fume-exhausting
The air channel of machine is discharged in external environment condition, causes the corrosion to air duct of range hood or the harmful effect to environment.
The content of the invention
The technical problem to be solved is the problem existed for above-mentioned prior art, there is provided one kind improves grease
The filter for range hood of separative efficiency.
The present invention solve the technical scheme that adopted of above-mentioned technical problem for：A kind of filter for range hood,

Also including the dividing plate of strip, the dividing plate extends straight up the filter from the first oil strain unit.
Optionally, the section of the dividing plate is in I fonts, Y-shaped or T fonts.
For increase oil smoke impact area, lifted filter efficiency, adjacent the first oil strain unit and the second oil strain unit it
Between be additionally provided with the baffle plate of strip, the baffle plate is obliquely installed into：The upper side edge of baffle plate extends to the edge of the second oil strain unit,
The lower side of baffle plate extends to the respective edges of the first oil strain unit, and the ventilation that multiple confession oil smoke pass through is offered on the baffle plate
Hole.
Preferably, the incline direction of two pieces of adjacent baffle plates intersects and is in splayed configuration or inverse Ba type arrangement, so as to first
Oil strain unit, the second oil strain unit and baffle plate constitute the undaform oil filtering plate for oil that section is broken line or camber line.
To simplify structure, strengthen intensity, the first oil strain unit, the second oil strain unit, dividing plate and baffle plate are integrally formed.
In order to realize lifting grease filtrating ability, and windage, the first oil strain unit, the second oil strain list are reduced as far as possible
The length of unit, dividing plate and baffle plate is L, draught area s1=a1*L between two neighboring first oil strain unit, and wherein a1 is
Spacing between two the first oil strain unit neighboring edges；Total draught area s2=a2*L of the air vent, wherein a2 is logical
Length of the air holes on baffle plate incline direction；Draught area s3=a3*L between the dividing plate and the second oil strain unit, wherein
A3 is the spacing between dividing plate and the second adjacent oil strain cell edges, and the relation between above-mentioned s1, s2 and s3 is as follows：0.3≤
S2/s1≤1,0.5≤s3/s2≤2.
There is a steering before by air vent to allow air-flow, and by hitting dividing plate after air vent, it is described
The angle of inclination of baffle plate be β, 30 °≤β≤90 °.
Compared with prior art, it is an advantage of the current invention that：By arranging the dividing plate for vertically extending on oil strain unit, increase
The probability for having added oil smoke to collide, improves grease filtrating ability；Position, size to oil strain unit and dividing plate is optimized, real
Grease filtrating ability is now lifted, and reduces windage as far as possible.
