At present, the oil-net structure that is arranged at the air inlet of kitchen ventilator place has following several:

1. the fine and close screen pack that adopts one or more layers to be consisted of by filament or consist of with the metal plate of countless apertures, but because the function of screen pack own is exactly filter effect, therefore oil dripping and oil leakage phenomenon in use, often can occur in the Oil Guide function that not have effect to get well.

2. one or more layers screen pack is adopted in inside, the outside adopts layer of metal post net as the Oil Guide effect, this structure is better than said structure, but because metal column resembles the chopsticks of water conservancy diversion, need enough large angle, just more effective, therefore its appearance is subjected to larger restriction, oil droplet is still more ugly on metal column simultaneously.

3. one or more layers screen pack is adopted in inside, (some makes U-shaped or arc flange) of one deck band ventilating opening adopted in the outside, but its flange is contour, and the direction of ventilating opening do not carried out multi-angle and process, therefore oil droplet can not effectively enter oil guide groove, so the phenomenon of oil dripping is arranged also.

4. adopt single-layer metal strip ventilating opening, do not have filter screen structure, this kind structure is to have a greatly reduced quality to filter effect, will have a strong impact on internal structure.

5. adopt the ventilating opening of double-level-metal strip flange, flange is relative, mutual misconstruction, i.e. tile type structure is because air-flow will beat and curved come in, therefore windage is very large, very large on the air quantity impact.

6. adopt the ventilating opening of double-level-metal strip flange, flange direction one to, this structure is little with the 4th difference.

Summary of the invention

The purpose of this utility model is to provide a kind of Novel oil net structure, have that filtering oil smoke is effective, wind loss is few, noise is low, easy to clean, the hidden danger that do not have oil dripping and leakage of oil, can effectively prolong the cooking-fume exhauster blower system the advantages such as non-maintaining time, overcome the shortcoming and defect that exists in the prior art.

To achieve these goals, the technical solution of the utility model is: a kind of Novel oil net structure, it is characterized in that: described oil-net structure contains the three-layer network body at least, be respectively outer layer net, middle level dictyosome and inner layer net body, oil network is followed successively by inner layer net body, middle level dictyosome, outer layer net from top to bottom, and described outer layer net is arranged by some bodys and formed, and body offers breach along its length, the cross section of body becomes ∪ shape or circular-arc or V-arrangement, and dictyosome place, described middle level forms some filter bores.

The utility model discloses a kind of Novel oil net structure, its filtering oil smoke is effective, wind loss is few, noise is low, easy to clean, cost is low, appearance does not have obvious greasy dirt, do not have the hidden danger of oil dripping and leakage of oil, can effectively prolong the cooking-fume exhauster blower system the advantages such as non-maintaining time.

Most of oil smoke adheres to its surface behind the effective aperture that shows as by screen pack of filtering oil smoke, and filter effect should obviously be better than adopting the mode of the direct punching of metallic plate.

Few and the noise of wind loss is low show as the second layer of this oil-net structure and the 3rd layer in fact on ventilation without any impact, draught area depends primarily on the area in the strip hole that the ground floor outer net opens, the area sum of strip hole should be greater than the air-admitting surface of inner blower fan in theory, the air quantity loss of this blower fan is extremely low, but the words that the air quantity loss is few are the rotating speed relative reduce of blower fan when reaching same Wind Volume, therefore that noise also shows is lower.

What the three-layer network that shows as this structure easy to clean really need to clean is second layer screen pack, illustrated that above screen pack suggestion adopts the small-bore net that is formed by the stainless steel wire braiding that can directly buy on the market, therefore two kinds of method reply cleanings are arranged, 1, do not want that the user who cleans can directly buy this net, and be cut into needed screen pack with scissors and change.2. rinse after washing immersion with boiling water and cleaning, if there is dish-washing machine to clean more convenient.

Cost is low to show as screen pack does not need specially, can directly buy by market.

Because this structure has just entered the U-shaped oil guide groove behind the oil droplet that screen pack is built up, therefore appearance does not have obvious greasy dirt, also do not have the hidden danger of oil dripping and leakage of oil.

Because the structure superior function of this oil network, can effectively prolong in addition the cooking-fume exhauster blower system the advantages such as non-maintaining time.

The specific embodiment

With reference to the accompanying drawings, the utility model further is described.

The utility model is a kind of Novel oil net structure, as shown in fig. 1, it comprises that mainly described oil-net structure contains the three-layer network body at least, be respectively outer layer net 1, middle level dictyosome 2 and inner layer net body 3, oil network is followed successively by inner layer net body 3 from top to bottom, middle level dictyosome 2, outer layer net 1, described outer layer net is arranged by some bodys 4 and is formed, body 4 offers breach 5 along its length, the cross section of body 4 becomes ∪ shape or circular-arc or V-arrangement, dictyosome 2 places, described middle level form some filter bores 7, the aperture of filter bores 7 is smaller, in the specific implementation, described middle level dictyosome 2 is made of one deck screen pack at least, described screen pack is made of wire cross, forms filter bores 7 between the wire, and filter bores 7 apertures are 1mm-3mm, its effect be by less aperture at utmost filter out pass through oil smoke (screen pack can multiple-layer stacked or combination in principle, specifically follows according to user's demand and decides) in the flue gas.
