Abstract
The oil screen of smoke exhaust ventilator that this utility model provides, including interior oil network and outer oil network, described outer oil network surrounding is downwardly projecting in back taper mesa-shaped, and core is protruding upward in frustum；Described interior oil network shape is identical with described outer oil network, overlays in described outer oil network and leaves gap, described interior oil network and described outer oil network therewith and is equipped with some through holes, is provided with and connects lubricating cup bottom described outer oil network.Use this utility model oil smoke smooth to enter, increase the suction of lampblack absorber；This oil network surrounding is then inverted cone, has ratio general inverted cone oil network more preferable oil smoke separating effect in the case of oil network height is identical, and bevel inclination angle can guarantee that more greatly Oil Guide effect simultaneously.
Description
Technical field
This utility model belongs to lampblack absorber field, relates to a kind of oil screen of smoke exhaust ventilator.
Background technology
Oil screen of smoke exhaust ventilator is varied in the market, substantially has following several:
The first is oil guidance column or oil guide groove adds solid filter net type, this kind of device because using solid filter net,
Therefore during range hood uses, it is easily caused mesh block, the Oil Guide poor effect of solid filter net,
In the case of oil network angle of inclination is big not, it is easily caused greasy dirt and directly drops onto the kitchen range top along oil network outer surface；
The second is monolayer circle or Long Circle through-hole structure, this kind of structure filtering oil smoke weak effect, and does not has
It is fully connected inside air channel, during air channel internal droplets drippage, may pass through air vent and directly drop onto the kitchen range top；
The third is double-deck tile type structure, as cranky in double-deck button type oil network air flue, airflow passes oil
During net, air intake resistance is very big, and air-flow extremely has some setbacks, and produces a lot of eddy current, and noise is very big, and air quantity is also
Cannot promote；
4th kind is bilayer " U " type structure in the same direction, although this structure air intake is smooth and easy, but this structure oil smoke
Inferior separating effect, oil smoke is directly inhaled in blower fan, affects service life of fan.
This utility model has carried out innovative design on the basis of " U " type structure in the same direction, to overcome it original
Defect.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of oil screen of smoke exhaust ventilator, both ensure that air intake led to
Freely, the advantage that noise is little, add again filtering oil smoke area, make oil smoke separating effect significantly promote.
To achieve these goals, the technical scheme that this utility model is taked is:
Described oil screen of smoke exhaust ventilator, including interior oil network and outer oil network, described outer oil network surrounding downwardly projecting in
Back taper mesa-shaped, core is protruding upward in frustum；Described interior oil network shape is identical with described outer oil network,
In overlaying described outer oil network and leave gap, described interior oil network and described outer oil network therewith and be equipped with some logical
Hole, is provided with bottom described outer oil network and connects lubricating cup.
If the through hole in described outer oil network is equally distributed along the inside and outside frustum inclined-plane circumference of described outer oil network
The dry bar hole extended to bottom described outer oil network.
The fin that some shaped positions are corresponding with described bar hole, described interior oil it is provided with outside described interior oil network
The through hole of net is the small sircle hole being uniformly arranged.
The interior oil network bound edge of annular is arranged at the top of described interior oil network.
The described lubricating cup that connects is the circulus matched with described outer oil network bottom shape.
Using technique scheme, the mid portion of this oil network is identical with deep suction type oil network shape, and oil smoke can
Smooth entrance, increases the suction of lampblack absorber；This oil network surrounding is then inverted cone, identical at oil network height
In the case of have and have more preferable oil smoke separating effect than general inverted cone oil network, bevel inclination angle is bigger simultaneously
Can guarantee that Oil Guide effect.
Connecing lubricating cup uses circulus to adapt to oil network bottom shape, saves material, it is ensured that greasy dirt focuses on and connects
In lubricating cup.Bar hole reduces air intake resistance, and air intake is unobstructed, and greasy dirt is along under the marginal flow in hole, it is simple to collect.
Interior oil network increases contact area by fin, improves oil smoke separating effect.Will when interior oil network bound edge prevents from installing
Hands scratches.
Accompanying drawing explanation
Fig. 1 is STRUCTURE DECOMPOSITION figure of the present utility model；
Fig. 2 is the structure chart after this utility model is completed；
Fig. 3 is the partial sectional view within this utility model, and arrow represents oil smoke flow direction.
Being labeled as in figure:
1, interior oil network bound edge；2, interior oil network；3, outer oil network；4, lubricating cup is connect；5, fin；6, bar shaped
Hole.
Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, this utility model detailed description of the invention is made into one
Step detailed description, to help those skilled in the art to have the present utility model design, technical scheme
More complete, accurate and deep understanding.
As shown in Figure 1 to Figure 3, this utility model provides a kind of oil screen of smoke exhaust ventilator, including interior oil network 2
With outer oil network 3, being both drawing and forming, shape is identical.It is all that surrounding is downwardly projecting in back taper mesa-shaped, in
Heart part is protruding upward in frustum.Interior oil network 2 small volume, overlays in outer oil network 3, between the two
Leave certain interval, as the air channel dynamic for oil smoke flow.
Described interior oil network 2 and described outer oil network 3 are equipped with the circulation of some through hole supplied gas.In outer oil network 3
Through hole is the inside and outside frustum inclined-plane equally distributed some bar holes 6 of circumference along described outer oil network 3.Bar hole
6 extend to bottom outer oil network 3, be provided with and connect lubricating cup 4 bottom outer oil network 3.Interior oil network 2 is then evenly distributed with
Small sircle hole (is not drawn in accompanying drawing), plays ventilation oil strain effect.Be provided with outside interior oil network 2 some shaped positions with
The fin 5 that described bar hole 6 is corresponding, increases the contact area with oil smoke, improves separating effect and also can guide
Greasy dirt flows to.
Connecing lubricating cup 4 is the circulus matched with outer oil network 3 bottom shape, is removably mounted on outer oil
Bottom net 3.Greasy dirt flows downwardly into connect lubricating cup 4 along fin 5 and bar hole 6 edge.The top of interior oil network 2 has
The interior oil network bound edge 1 of annular, convenient installation, and effectively prevent from scratching the hands of setter.
Oil network generally inverted cone-shaped, in conjunction with the deep suction part of middle conve shaped, oil network cross section forms a waveform.
This structure can make oil smoke smoothness enter oil network, and oil smoke flow direction is as shown in Figure 3；Oil smoke and interior can be made again
Net is fully contacted, and makes the oil molecule in oil smoke separate, and flows into along oil network under gravity and connects oil
Cup 4.
Above in conjunction with accompanying drawing, this utility model is exemplarily described, it is clear that this utility model implements
It is not subject to the restrictions described above, as long as it is each with what technical scheme was carried out to have employed the design of this utility model method
The improvement of kind of unsubstantiality, or the most improved this utility model design and technical scheme are directly applied to other
Occasion, all within this utility model protection domain.
