Description
Technical field
The utility model relates to a kind of filter, relates in particular to a kind of cooking fume filter.
Background technology
Cooking fume filter is an indispensable vitals in the smoke exhaust ventilator for cooking, directly influences the result of use of smoke exhaust ventilator.
Chinese patent specification 02221725.8 (bulletin on January 8th, 2003) discloses a kind of cooking fume filter, this cooking fume filter is a slab construction, have oil smoke import and air outlet slit on it, slab construction is formed by forward and backward two, have therebetween at interval, oil smoke import on the anter and the air outlet slit on the rear panel all are that cross section is trapezoidal bar hole, and oil smoke import and air outlet slit are staggered.
Chinese patent specification 200420050894.7 (bulletin on February 16th, 2005) discloses a kind of vortex type gas filter, it is installed on vortex type gas filter housing or the framework by the cross arrangement of spirality roll bending, forms air inlet, gas outlet and spiral vortex type passage.
These utility model common characteristic are two-layer combinations of adopting air intake plate and go out aerofoil on the structure, the passage that formation makes air flow and transfer suddenly, drive by fume exhauster motor, the air of carrying oil smoke secretly is sucked from air inlet, channel separation by complications goes out tiny oil droplets, oil droplet accumulates in air intake plate or goes out on the aerofoil, and flows in the oil sump tank under the effect of gravity.The shortcoming of these cooking fume filters is: (1) single filtration, poor filtration effect; (2) no-buffer or buffering area are few, and the mist of oil collision frequency is few; (3) passage is relatively more tortuous, and air flows and has some setbacks, and suction effect is poor, and power of motor expends bigger.
The utility model content
The purpose of this utility model is exactly in order to overcome the above shortcoming of existing cooking fume filter, and the cooking fume filter that a kind of oil smoke separating effect is better, air flow passage is more smooth and easy, power consumption is less is provided.
The utility model is achieved through the following technical solutions:
The cooking fume filter that the utility model provides comprises air intake plate, goes out aerofoil and oil-collecting plate, has therebetween at interval, air intake plate is provided with the oil smoke air inlet, go out aerofoil and be provided with air outlet slit, oil-collecting plate is provided with passage, and passage and oil smoke air inlet, air outlet slit are staggered.
In such scheme:
Oil-collecting plate can be arranged on air intake plate and go out between the aerofoil.
Oil-collecting plate can be arranged on the air intake plate front or go out the aerofoil back.
Oil-collecting plate can be arranged on the air intake plate front simultaneously and go out the aerofoil back.
Oil-collecting plate can be arranged on air intake plate and go out between the aerofoil, and in the air intake plate front or go out the aerofoil back and add oil-collecting plate.
Oil-collecting plate can and go out between the aerofoil at air intake plate, air intake plate front and go out the aerofoil back and be provided with simultaneously.
In upper type, oil-collecting plate can select to be provided with one or more as required.Like this, make oil smoke pass through multiple times of filtration before emitting, filter effect is better.
The utility model can adopt slab construction or arcuate structure.
Operation principle of the present utility model is: utilize air intake plate, oil-collecting plate and go out a plurality of passages of turning back suddenly and the zone that forms between the aerofoil, form many places turbulent flow, eddy current buffering area, increase the chance of oil mist particles collision and cohesion.Therefore, oil smoke is each through turning back during passage of forming between the adjacent two boards, the fine oil mist particle all runs foul of each other in the district in corresponding the delaying that this passage of turning back forms and is condensed into bigger oil droplet, under centrifugal force, inertia force, gravity effect, elaioleucite accumulates in a side of plate, and oil smoke obtains primary purification.Correspondingly, the passage of turning back suddenly that between oil smoke is repeatedly through plate and plate, forms, oil smoke is correspondingly repeatedly purified, and filter effect is more remarkable.Simultaneously, the oil smoke channels designs that the utility model adopts is smooth and easy, and the mobile speed ratio of air changes little, makes power consumption reduce, and noise is littler.
Air intake plate of the present utility model, go out aerofoil and can select different shapes as required for use with oil-collecting plate, as air intake plate, oil-collecting plate, to go out the aerofoil side view can be plane, cambered surface, curved surface, front shape can be circle, rectangle, triangle or other geometries; The structure of plate can adopt strip structure or hole shape structure, the cross sectional shape of strip structure can be arc, trapezoidal, rectangle etc., and the cross sectional shape of hole shape structure can be selected trapezoidal, rectangle, the type in hole can be flat hole, monolateral hole flanging or bilateral anti-hole, the shape in hole can be circle, rectangle, ellipse or other shapes and can make up mutually that the size in hole can be that bigger hole also can be the mesh than comparatively dense.Air intake plate, going out aerofoil and oil-collecting plate can be according to changing with upper type or makes up variation separately, but various compound mode must form filtration channel.
The utlity model has following beneficial effect:
(1) adopt multi-filtering, filter between oil and the cigarette more thorough, environmentally-friendly sanitary;
(2) air flow passage is smooth and easy, less energy consumption, and noise is little;
(3) air intake plate, go out aerofoil and the board-like combination of oil-collecting plate is changeable, accessory is changed convenient, is easy to clean.
