In the figure, the oil smoke separator of the kitchen range hood is shown in the embodiment, the oil smoke separator is a flow guide grid 1 formed by sequentially aligning, arranging and fixing flow guide vanes 1.1 one by one, wherein the left side wall and the right side wall of the flow guide vane 1.1 are wavy curved surfaces, the cross section of the flow guide vane 1.1 is of a wavy structure, a plurality of positioning members 1.11 used for being connected in series are arranged on the left side wall and the right side wall of the flow guide vane 1.1, ventilation gaps are formed between the adjacent flow guide vanes, the ventilation gaps form a ventilation isolating channel 1.15, the ventilation isolating channel 1.15 is in a wavy and zigzag state, the lower side of the flow guide grid 1 is an oil smoke inlet 1.112A, the oil smoke enters the flow guide grid 1 through the oil smoke inlet 1.112A, repeatedly collides with the side walls of the flow guide vane 1.1 in a zigzag path and then is discharged from the oil smoke outlet 1.. Fig. 2 shows that, in the present example, the flow guide vanes 1.1 are of a longitudinally rectilinear configuration. The utility model discloses the suggestion because the water conservancy diversion grid can form a large-capacity space in inside, consequently has the ability of confinement in the twinkling of an eye and absorbing a large amount of smog to because the oil smoke bumps with the lateral wall many times in ventilating separating the way, consequently the probability of oil mist adhesion increases greatly, makes the oil smoke separation rate can obtain obvious promotion.
Fig. 5 shows that, in this example, the air duct 1.15 has 6 bending points. The utility model discloses the suggestion, in other embodiments, it is preferred, 2-6 can be selected to the wind separation bend point.
The utility model discloses the suggestion, the whole size of considering oil smoke separator and the collision adhesion effect of oil mist in the oil smoke comprehensively, in this example, the thickness B of oil smoke separator (namely the height between lower bottom surface 1A and upper top surface 1B) can select 20mm-120 mm; the ventilation ducts can be referenced to the following dimensions: the bending angle alpha can be selected from 90-130 degrees; the width-length ratio of the ventilation partition, namely the ratio of the width A to the bending length L, is 0.2-0.5 (namely the ratio of A/L is more than or equal to 0.2 and less than or equal to 0.5); the absolute dimension of the width A can be chosen to be between 2.5mm and 30 mm. The design of the ventilation partition channel directly influences the ventilation effect, and under the condition that the thickness of the oil fume separator is not changed, the size of the width A is reduced, the ventilation section is reduced, and the ventilation resistance is increased; the width-length ratio A/L is reduced, and the ventilation resistance is increased; the more the bending point, the larger the ventilation resistance. And the larger the ventilation resistance, the better the adhesion effect of the oil mist.
Fig. 2 and 4 show that in this case the guide vanes 1.1 are also provided with panels 1.12 in cross-section (transverse direction).
