[embodiment description]
Shown in Figure 1 is the part assembly drawing of smoke exhaust ventilator 100 according to the preferred embodiment of the present invention.This smoke exhaust ventilator 100 is installed on the side walls in kitchen usually, is used for taking away and filter in the kitchen oil smoke that produces in the cooking process especially.Shown in 1 figure, this smoke exhaust ventilator 100 comprises housing 1, suction force generation device 2 and filter.Housing 1 is in order to assembling other each parts and to be positioned on the wall, and housing 1 has allows oil smoke enter smoke exhaust ventilator, be approximately perpendicular to the suction inlet (not shown) of this wall.Described suction force generation device 2 is in order to the generation suction force, thereby with this suction inlet of oil smoke inspiration, this suction force generation device 2 generally includes motor and fan, and its principle and structure are known by the those of ordinary skill in smoke exhaust ventilator field, are not described in detail here.
Please refer to Fig. 1 and 2, described oil-filtering apparatus is installed on the described suction inlet, carries out grease in order to the oil smoke that will suck and separates, and the fluid that the process oil-filtering apparatus separates, filters is received by the oil catcher (not shown) of the below that is installed in this oil-filtering apparatus.This oil-filtering apparatus comprises filter frame 3 and is installed in this filter frame 3 inner filtering layers 4.When oil smoke entered suction inlet, filter frame 3 at first filtered it, thereby filtering layer 4 then carries out the filter effect that further oil smoke separates the smoke exhaust ventilator of optimizing 100 to the oil smoke that filters through filter frame 3.
As shown in Figure 3 and Figure 4, filter frame 3 is made by a metallic plate, and the polyhedral cone shape that it roughly is butt has four conical surfaces 30, all be distributed with the lengthening bar shaped flange hole 31 that several are arranged parallel to each other on each conical surface 30, this flange hole 31 can be by forming by punching press.Constitute oil guide groove 32 between the adjacent flange 31a in adjacent bar shaped flange hole 31, like this when oil smoke during through filter frame 3, it is interior and flow in the oil catcher of the awl bottom that is connected filter frame 3 along the incline direction of the conical surface 30 that the oil droplet that gets off of condensing can accumulate in oil guide groove 32.
As Fig. 5, Fig. 6 and shown in Figure 7, filtering layer 4 is a jointless structure, forms with metal wire knitted, has some passages 40 so that oil smoke is discharged outdoor by this passage 40.Filtering layer 4 can be an individual layer, also can be multilayer.Certainly, described filtering layer 4 can be by forming in metallic plate upper punch hole.
As Fig. 5, shown in Figure 6, the first frustum portion 41 of this filtering layer 4 and each conical surface of the second frustum portion 42 form ripple respectively, and ripple comprises crest 4a and trough 4b.Described crest 4a is the upper surface of relative filtering layer with trough 4b, i.e. the outer surface of the inner surface of the first frustum portion 41 and the second frustum portion 42.The crest 4a of the crest 4a of the first frustum portion 41, trough 4b and the second frustum portion 42, trough 4b extend towards the bottom surface of the first frustum portion 41 or the bottom surface of the second frustum portion 42 respectively, thereby form oil outlet passage, make the flow direction of fluid clear and definite.Described crest 4a and trough 4b are the radioactivity setting on the same conical surface.
As shown in Figure 8, on identical cross section, be uninterrupted connection between crest 41a and the trough 41b, the distance between each crest 41a and the trough 41b (being amplitude) equates; On different cross sections, this distance reduces gradually along with the downward convergent of the conical surface.Yet, the said ripple of the present invention, not only comprise the identical concaveconvex structure of amplitude on the same cross section, also should be included in the unequal situation of distance between each crest 41a and trough 41b on the same cross section, and on same cross section height at grade the situation not of crest 41a or trough 41b.
When smoke exhaust ventilator 100 work, the oil smoke that the kitchen especially produces in cooking process enters filter frame 3 from suction inlet, and is discharged from outdoor by filtering layer 4.In this process, oil smoke makes mist of oil wherein be condensed into oil droplet with filter frame 3 collisions earlier, and these oil droplets can flow to along oil guide groove 32 and be connected in the filter frame oil catcher at the 3 awl ends.Through the filter frame 3 preliminary oil smoke that filter and then with filtering layer 4 collisions grease is separated from oil smoke, the grease that is separated is distributed on the upper surface and lower surface of filtering layer 4, these greases can flow to oil catcher respectively on filtering layer 4 upper surfaces and lower surface, on the lower surface of filtering layer 4, especially the crest 4a along ripple flows, and then flows along trough 4b on upper surface.Wherein the oil droplet in the first frustum portion 41 flows towards oil catcher.Oil droplet in the second frustum portion 42 then flows towards the zone that filter frame 3 is not provided with flange hole 31, and the oil guide groove 32 by filter frame finally flows to oil catcher.
As shown in Figure 9, on y direction, has the gap between filtering layer 4 and the filter frame 3.From the bearing of trend of oil guide groove 32 to oil catcher, crest 4a on the conical surface 30 of filter frame 3 and the corresponding conical surface of filtering layer 4 or the gap between the surface, trough 4b place increase afterwards earlier and reduce.The junction of the first frustum portion 41 and the second frustum portion 42 and filter frame 3 have maximum gap, and in the first frustum portion 41 and second frustum portion 42 zone separately, described gap is more down more little.
Because the cone angle of the 41 crest 4a of the first frustum portion and the trough 4b place conical surface is less than the cone angle of the filter frame 3 corresponding conical surfaces, thereby the conical surface of the relative filter frame 3 of the conical surface of the first frustum portion 41 has bigger oil extraction angle, this can improve flowing of oil, makes its flow direction clearer and more definite.
In the above-described embodiment, first, second frustum portion 41,42 of described filter frame 3 and filtering layer 4 all is the structure with four sides frustum, yet described filter frame 3 and filtering layer 4 also can adopt the structure of circular cone structure or other multiaspect frustums.
