Abstract
This utility model is related to a kind of oven oil smoke filtering device, including the gas outlet being arranged on oven inner container top, and be arranged on drainage screen in gas outlet it is characterised in that：The exit of gas outlet is provided with the ventilative pipe that can dismantle, and the outlet surrounding being located at gas outlet, the top setting air outlet of this ventilative pipe are enclosed in the bottom of this ventilative pipe, and the top cross-section of this ventilative pipe is less than the bottom section of ventilative pipe, so that the tapered structure of ventilative pipe.Compared with prior art, the utility model has the advantage of：Using oil smoke result from 170 DEG C and more than, it is made up of organic principles such as aldehyde, ketone, hydrocarbon, fatty acid, lactone, aromatic compounds, when oven temperature reach 170 DEG C and more than, the gaseous mixture such as oil smoke and air knows from experience expanded by heating, produces lift upwards, cause gaseous mixture to be known from experience and pass through drainage screen, due to the tapered structure of ventilative pipe, oil smoke can be made to be deposited on the internal face of ventilative pipe, without power resources, ventilative pipe can disassemble cleaning, and filter effect is preferable.
Description
Technical field
This utility model is related to a kind of oven oil smoke filtering device.
Background technology
With the development of foreign trade, people increasingly like Western-style cooking method.Self-control DIY cake, baking meat
Fallen over each other to pursue by people Deng diet style.Therefore, baking box also receives highest attention as new cooking tools.Meanwhile,
People increasingly dislike for the oil smoke producing during baking, and therefore reducing baking oil smoke becomes the task of top priority.
There is problems with existing filtration：1st, the gases such as power set (as fan) guiding oil smoke are needed to pass through
Filter structure；2nd, need high temperature, catalyst etc. that oil smoke mixing gas is aoxidized；3rd, be inconvenient to dismantle, poor filtration effect etc. is asked
Topic.
Utility model content
Technical problem to be solved in the utility model is to provide one kind without power resources, side for above-mentioned prior art
Just dismounting, the preferable oven oil smoke filtering device of filter effect.
This utility model solves the technical scheme that adopted of above-mentioned technical problem：A kind of oven oil smoke filtering device, bag
Include the gas outlet being arranged on oven inner container top, and be arranged on drainage screen in gas outlet it is characterised in that：Described gas outlet
Exit be provided with the ventilative pipe that can dismantle, the outlet surrounding being located at gas outlet, the top of this ventilative pipe are enclosed in the bottom of this ventilative pipe
Portion arranges air outlet, and the top cross-section of this ventilative pipe is less than the bottom section of ventilative pipe, so that the tapered structure of ventilative pipe.
As improvement, described drainage screen is by the first diamond hole drainage screen positioned at lower floor, the carbon fiber filter positioned at middle level
Net and the second diamond hole drainage screen positioned at upper strata are formed by stacking.
Improve again, the surrounding of drainage screen is fixed by frame, this frame can be dismantled on the oven inner container being fixed on.
Improve again, the 1/8～1/ of the gas outlet diameter at air outlet a diameter of oven inner container top at described ventilative pipe top
5.
Compared with prior art, the utility model has the advantage of：Using oil smoke result from 170 DEG C and more than, by aldehyde,
The organic principles such as ketone, hydrocarbon, fatty acid, lactone, aromatic compound form, when oven temperature reach 170 DEG C and more than, oil smoke and
The gaseous mixtures such as air know from experience expanded by heating, produce lift upwards, cause gaseous mixture to be known from experience and pass through drainage screen, because ventilative pipe is in
Pyramidal structure, can make oil smoke be deposited on the internal face of ventilative pipe, without power resources, ventilative pipe can disassemble cleaning,
And filter effect is preferable.
Brief description
Fig. 1 is the structural representation of oven oil smoke filtering device in this utility model embodiment；
Fig. 2 is I portion enlarged drawing in Fig. 1.
Specific embodiment
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
Oven oil smoke filtering device as shown in Figure 1, including the gas outlet 21, Yi Jishe being arranged on oven inner container 2 top
Put the drainage screen 3 in gas outlet, the exit stating gas outlet is provided with the ventilative pipe 1 that can dismantle, and the bottom of this ventilative pipe 1 is enclosed and set
In the outlet surrounding of gas outlet, the top setting air outlet 11 of this ventilative pipe 1, and the top cross-section of this ventilative pipe 1 are less than ventilative
The bottom section of pipe, so that the tapered structure of ventilative pipe, the going out of air outlet a diameter of oven inner container top at ventilative pipe top
The 1/6 of QI KOU diameter.
In the present embodiment, described drainage screen comprises the first diamond hole drainage screen 31 positioned at lower floor, and the carbon positioned at middle level is fine
Dimensional filter net 32, and it is located at the second diamond hole drainage screen 33 on upper strata, and the surrounding of drainage screen is passed through frame 4 and is fixed, this frame
Can dismantle on the oven inner container 2 being fixed on, shown in Figure 2.
Because drainage screen is formed by stacking by two-layer diamond hole drainage screen and one layer of high temperature flame-proof carbon fibre web, work as high-temperature oil smoke
And the mixed gas such as air are when passing through drainage screen, have the wall side that portion gas touch lower floor's the first diamond hole drainage screen, its
Fortune work(can change direction, and produces the loss of momentum and thermal loss, and then, gas passes through carbon fiber filter net, due to the suction of carbon
Attached effect, can adsorb a part of gas, and gas not to be adsorbed, as momentum is produced by fine and close sponge structure
Loss, that is, gas motion speed reduces further, and finally, gas can still can again by the second diamond hole drainage screen on upper strata
Portion gas are had to collide with wall, thus producing the loss of momentum, thermal loss, therefore when gas passes through drainage screen, greatly
Portion gas all have passed through the loss of momentum at least one times；Afterwards, mixed gas, will enter ventilative pipe.Because ventilative pipe is designed as
Up-small and down-big conical structure, therefore when gas through drainage screen mesh-structured after, area of section that it can pass through is dashed forward
So increased more than several times, from flow rate calculation formula, when flow is constant, and area of section increases several times, its gas flow rate
Several times can be reduced；Again because the molecular mass of oil smoke in mixed gas is higher than the quality of other molecules of in the air, therefore work as stream
Prompt drop is low, and the high oil smoke of molecular mass can gradually deposit；In addition, diamond hole drainage screen fluid motion direction before
Change, oil smoke can be made to be easier near ventilative tube wall face, and now oil smoke viscosity is very strong, be therefore easier to be attached to wall it
On.In sum, even if the adsorption function of carbon fibre web is lost in this programme, its lampblack filtering function still exists.This programme
In drainage screen, ventilative pipe be demountable structure, be easy to clean.
