DETAILED DESCRIPTION

[0037] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0038] The utility model relates to an oil fume separation disc group, comprising a base plate 100, a first blade 200 and a second blade 300.

[0039] like Figure 1 , Figure 2 and Figure 5 As shown, the substrate 100 is configured as a plate-like structure. The circumferential contour shape of the substrate 100 is not limited and may be a triangle, rectangle or other polygon, etc. In the present embodiment, the substrate 100 is preferably a circular plate. A plurality of first clamping positions 110 are provided on the substrate 100. The first clamping positions 110 are sequentially distributed along the circumference of the substrate 100. The first clamping positions 110 may be provided at a non-peripheral position of the substrate 100 or at a peripheral position of the substrate 100. The first blade 200 and the second blade 300 are both mounted on the substrate 100 through the clamping positions. The plurality of first blades 200 are sequentially installed on the first clamping positions 110 along the circumference of the substrate 100 and are radially distributed. The first blades 200 are at the same height on the substrate 100, and there is a certain distance between two adjacent first blades 200, which is defined as a first interval 201. The first blade 200 is in the shape of an elongated strip and extends radially along the substrate 100. The long sides of the first blade 200 are bent or curved in the same direction. As shown Figure 3 As shown, the left and right long sides of the first blade 200 are bent downward, and the first flow groove 210 is defined between the opposite sides of the left and right long sides and the downward blade surface of the middle part of the first blade 200. The first flow groove 210 is downward and extends in the radial direction of the substrate 100. The cross section of the first blade 200 is U-shaped. It can also be, as Fig. 9 As shown, the long sides of the first blade 200 are bent from the center line of the first blade 200, and the cross section of the first blade 200 is V-shaped. Fig.10As shown, after the long sides of the first blade 200 are bent, the middle part of the first blade 200 protrudes in a V shape along the middle part, and the cross-section of the first blade 200 is W-shaped. The first blade 200 can also be in other shapes. Multiple second blades 300 are installed in sequence on the second clamping position 501 along the circumference of the substrate 100 and are distributed radially. The second blades 300 and the first blades 200 are distributed axially on the substrate 100. Each second blade 300 is at the same height on the substrate 100. In the direction shown in the figure, each first blade 200 and each second blade 300 are distributed up and down. There is a certain distance between two adjacent second blades 300, and the distance is defined as the second interval 301. The second blade 300 is in the shape of a long strip and extends radially along the substrate 100. The long sides of the second blade 300 are bent or curved in the same direction. Among them, the second blade 300 can be set to the same shape as the first blade 200, that is, the second blade 300 is set to have a U-shape, a V-shape or a W-shape in cross-section. Correspondingly, as Figure 4 As shown, a second flow groove 310 is defined on the second blade 300, and the opening of the second flow groove 310 faces upward, and the second flow groove 310 extends along the axial direction of the substrate 100. The first blade 200 and the second blade 300 are offset up and down on the substrate 100. The first flow groove 210 on each first blade 200 is aligned with the second interval 301 one by one, and the opening of the first flow groove 210 faces the second interval 301. The second flow groove 310 on each second blade 300 is aligned with the second interval 301 one by one, and the opening of the second flow groove 310 faces upward to the first interval 201. In actual use, the oil fume separation disc group is applied to the oil fume separation device. The oil fume separation device also includes a housing 610 and a fan 620. As shown Fig.11 As shown, the outer shell 610 is configured as a hollow cylindrical structure with openings at the upper and lower ends. The interior of the outer shell 610 defines a smoke chamber, and the oil fume separation disc group is installed in the smoke chamber. The fan 620 is fixed to the outer shell 610 by a bracket. The fan 620 is coaxially connected to the base plate 100. The lower side of the second blade 300 is used as the air inlet side, and the upper side of the first blade 200 is used as the air outlet side. When the fan 620 rotates, the oil fume in the external environment will flow from the air inlet side to the air outlet side. When flowing, Figure 2As shown, the oil fume flows upward from the bottom of the second blade 300, and the oil fume collides with the lower side of the second blade 300 and is diverted to each second interval 301. After passing through the second interval 301, the oil fume will enter the first flow slot 210, and the oil fume will be diverted to both sides after impacting the slot wall of the first flow slot 210, and will change direction and flow downward along the left and right sides of the first flow slot 210 to enter the second flow slot 310. The oil fume then flows from the second flow slot 310 to the first interval 201 and is dispersed to the upper side of the first blade 200. When the oil fume flows along the second interval 301, the first flow slot 210, the second flow slot 310 and the first interval 201, it changes direction twice, and fully contacts and adheres to the inner walls of the first flow slot 210 and the second flow slot 310. At the same time, under the action of the motor driving the oil fume separation disc group to rotate, the first blade 200 and the second blade 300 shear the oil fume, and separate the grease in the oil fume from the smoke, thereby achieving an efficient purification effect on the oil fume. The grease in the first flow groove 210 and the second flow groove 310 flows radially outward during the rotation of the oil fume separation disc assembly. An oil collecting groove may also be provided on the housing 610 to collect the grease in the first flow groove 210 and the second flow groove 310 .

[0040] The utility model also relates to a range hood, which comprises a fume separation device. The range hood can well separate grease and smoke while extracting fume.

[0041] In some specific embodiments of the present invention, Figure 2 As shown, the long side of the first blade 200 extends into the second flow groove 310 opposite to it. That is, the long sides on the left and right sides of the first blade 200 are opposite to the second flow groove 310 respectively and extend into the second flow groove 310; correspondingly, the long sides on the left and right sides of the second blade 300 are also opposite to the first flow groove 210 respectively and extend into the second flow groove 310. It is equivalent to that the left long side of the first blade 200 is opposite to the right long side of the adjacent second blade 300 and there is a third interval 401 between the two, and the right long side of the first blade 200 is opposite to the left long side of the adjacent second blade 300 and there is a third interval 401 between the two. The first flow groove 210 and the second flow groove 310 are connected through the third interval 401, and the oil smoke must flow through the first flow groove 210 and the second flow groove 310 when flowing, ensuring that the oil smoke fully contacts the groove walls of the first flow groove 210 and the second flow groove 310 to separate the grease. The long side of the first blade 200 is parallel to the long side of the adjacent second blade 300 , so as to ensure that the oil smoke flows in and out of the third interval 401 stably.

[0042] In some specific embodiments of the present invention, Figure 3 , Figure 4 , Figure 5 and Figure 7As shown, the substrate 100 is a circular plate.

The first notch 221 and the third notch 321 are sequentially plugged into the first clamping position 110. That is, the two corners of the first end 220 are the first notch 221, and the two corners of the third end 320 are the third notch 321. The first notch 221 on both sides of the first end 220 are respectively plugged into the two first clamping positions 110. At this time, there is a vacant first clamping position 110 between the two first notches 221 of the same first end 220, one of the third notches 321 on the third end 320 is inserted into the vacant first clamping position 110 between the two first notches 221 of one first end 220, and another third notch 321 on the same third end 320 is inserted into the vacant first clamping position 110 between the two first notches 221 of another first end 220. Along the circumference of the substrate 100, the first clamping position 110 is inserted in the order of the first notch 221, the second notch 231, the first notch 221, the second notch 231, etc. After installation, the middle protrusion position of the first blade 200 is located on the upper side of the substrate 100, and the middle protrusion position of the second blade 300 is located on the lower side of the substrate 100. In this way, the staggered arrangement of the first flow slot 210 and the second flow slot 310 is ensured. The required thickness of the base plate 100 is small, and after installation, the axial height of the oil fume separation disc group on the base plate 100 is small, and the space occupied is small.

[0043] Further, such as Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 8As shown, a circular ring 500 is also included. A plurality of second clamping positions 501 are provided on the inner side of the circular ring 500, and the second clamping positions 501 are arranged along the circumference of the circular ring 500. The second clamping positions 501 are in the shape of a notch, and can be V-shaped or rectangular. Second notched corners 231 are provided on both sides of the second end 230, and fourth notched corners 331 are provided on both sides of the fourth end 330. That is, the two corners of the second end 230 are the second notched corners 231, and the two corners of the fourth end 330 are the fourth notched corners 331. The second notched corners 231 and the fourth notched corners 331 are sequentially plugged into the second clamping position 501.
