Mouthful mutually stagger between the adjacent thereto second opening so that front wing panel at first edge of opening and it is adjacent thereto after
It is spaced between wing plate and forms air flue of the connection between first opening and second opening, the both ends of the air flue is formed respectively
Air-flow turning point.Although above-mentioned lampblack filter oil filter effect is preferable, structure is complex, is further improved.
Utility model content
Technical problem to be solved in the utility model is to be directed to above-mentioned state of the art, there is provided it is a kind of it is simple in construction,
The Multistage filtering device for range hood of good filtration effect.
Technical scheme is used by the utility model solves above-mentioned technical problem：This is used for the multistage filtering of range hood
Device, it is characterised in that：Including oil filtering plate for oil, the oil filtering plate for oil has to the same side indent of oil filtering plate for oil and the U-shaped oil strain that is formed
Groove, the U-shaped oil strain groove are parallel to each other and are spaced apart successively, are had in the two opposite side walls of the U-shaped oil strain groove
First oil strain hole and the second oil strain hole, the first oil strain hole and the second oil strain hole are each along between the length direction of U-shaped oil strain groove
Stagger every distribution and mutually.
Dripped in order to avoid falling into after the oil droplet on oil filtering plate for oil passes through oil strain hole, the two opposite side walls of the U-shaped oil strain groove
It is vertically arranged.
As a kind of preferred scheme, the first oil strain hole and the second oil strain hole are complete on the length direction of U-shaped oil strain groove
It is completely wrong to open.
Further preferably, the first described oil strain hole is square hole with the second oil strain hole and size is identical, also, described
Between spacing and two the second adjacent oil strain holes between two relative edges of the one oil strain hole on U-shaped oil strain slot length direction
Spacing is equal.
Further preferably, the first described oil strain hole is square hole with the second oil strain hole and size is identical, also, described
It is smaller than between two relative edges of the one oil strain hole on U-shaped oil strain slot length direction between two the second adjacent oil strain holes
Spacing.
As another preferred scheme, the first oil strain hole and the second oil strain hole are on the length direction of U-shaped oil strain groove
Stagger part.
As another preferred scheme, the equal compartment of terrain cluster distribution in the first described oil strain hole and the second oil strain hole is each
The the first oil strain hole and the second oil strain hole of cluster include at least three holes, and arbitrary first oil strain hole and the arbitrary second filter
Projection no lap of the oilhole in same vertical plane.
Compared with prior art, the utility model has the advantage of：Due to the U-shaped oil strain of the Multistage filtering device oil filtering plate for oil
Groove is parallel to each other and is spaced apart successively, and the first oil strain hole in the two opposite side walls of U-shaped oil strain groove and the second oil strain hole are equal
Be spaced apart along the length direction of U-shaped oil strain groove and mutually stagger, therefore, into U-shaped oil strain groove oil smoke with oil strain groove
Inner surface while collide, moreover it is possible to collided through the first oil strain hole and the side wall of oil strain groove, so as to further improve oil strain effect
Fruit.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
Embodiment one：
As shown in figure 1, the Multistage filtering device in the present embodiment for range hood includes oil filtering plate for oil 1, oil filtering plate for oil 1 has
The U-shaped oil strain groove 11 formed to the same side indent of oil filtering plate for oil, U-shaped oil strain groove 11 is parallel to each other and is spaced apart successively, U-shaped
The two opposite side walls of oil strain groove 11 are vertically arranged.The first oil strain hole is had in the two opposite side walls of U-shaped oil strain groove 11
12 and the second oil strain hole 13, the first oil strain hole 12 and the second oil strain hole 13 each along U-shaped oil strain groove 11 length direction interval point
Cloth and mutually stagger.
In the present embodiment, the first oil strain hole 12 and the second oil strain hole 13 are completely wrong on the length direction of U-shaped oil strain groove 11
Open.A kind of preferred scheme is as shown in Fig. 2 the first oil strain hole 12 is square hole with the second oil strain hole 13 and size is identical, also,
Spacing and two the second adjacent oil strain holes 13 between two relative edges of the one oil strain hole 12 on the U-shaped length direction of oil strain groove 11
Between spacing it is equal.Another preferable scheme as shown in figure 3, the first oil strain hole 12 and the second oil strain hole 13 be square hole and
Size is identical, also, is smaller than two between two relative edges of the first oil strain hole 12 on the U-shaped length direction of oil strain groove 11
Spacing between the second adjacent oil strain hole 13.
As shown in figure 4, the length direction top misclassification of the first oil strain hole 12 and the second oil strain hole 13 in U-shaped oil strain groove 11
Open, i.e. the projection of the first oil strain hole 12 and the second oil strain hole 13 on same upright plane has lap.
The oil strain process of the filter of the present embodiment is as follows：
As shown in figure 5, the oil filtering plate for oil 1 is horizontally arranged at the bottom of the exhaust fume collecting hood 2 of range hood, oil smoke flows into from bottom to top
Oil filtering plate for oil 1, the oil strain groove sidewall through the oil smoke meeting in the first oil strain hole 12 and adjacent two second oil strain hole 13 are collided, passed through
Oil strain groove sidewall between the oil smoke meeting in the second oil strain hole 13 and adjacent two first oil strain hole 12 is collided, so, through oil filtering plate for oil 1
Oil smoke directly will not be penetrated between the first oil strain hole 12 and the second oil strain hole 13, but can pass through oil filtering plate for oil 1 repeatedly touch
Hit, so as to effectively improve the oil filter effect of oil filtering plate for oil.
Embodiment two：
