Detailed Description

In the figure, the oil smoke separator of a kitchen range hood is shown in the embodiment, the oil smoke separator is a flow guide grid 1 formed by superposing flow guide vanes 1.1 one by one up and down, the flow guide grid 1 is in a rectangular three-side frame structure, the upper side wall and the lower side wall of each flow guide vane 1.1 are in wave curved surfaces, the cross section of each flow guide vane 1.1 is in a wave structure (the longitudinal direction of each flow guide vane forms a rectangular three-side frame, each flow guide vane 1.1 is provided with two bending angles), the upper side wall and the lower side wall of each flow guide vane 1.1 are provided with a plurality of positioning members 1.11 used for serial connection, a ventilation gap is arranged between the adjacent flow guide vanes, the ventilation gap forms a ventilation isolating channel 1.15, the ventilation isolating channel 1.15 is in a zigzag wave state, each flow guide vane 1.1 is arranged in a horizontal state (namely, the vanes are in a horizontal state), each flow guide vane is in an up and down superposed state, the outer side of the frame of the flow guide grid 1 is an oil smoke inlet 1.19A and the inner side is an oil smoke outlet 1.19B, the oil smoke enters the flow guide grid 1 from the outer side of the frame through the oil smoke inlet 1.19A, Repeatedly collide with the side wall of the guide vane 1.1 in a zigzag path and then are discharged from the lampblack outlet 1.19B. The invention suggests that the guide grid 1 can form a large-volume space inside, so the guide grid has the capacity of instantly confining and absorbing a large amount of smoke, and the oil smoke collides with the side wall in the ventilation channel for many times, so the probability of oil mist adhesion is greatly increased, and the oil smoke separation rate can be obviously improved.

Fig. 5 shows that, in this example, the air duct 1.15 has 6 bending points. The figure shows that the oil smoke enters the diversion grating 1 from the outer side surface of the rectangular three-frame in the horizontal direction through the oil smoke inlet 1.19A, moves along the radial inner sides of the upper and lower zigzag paths in the ventilation isolating channel 1.15, repeatedly collides with the upper and lower side walls of the diversion blades and then is discharged from the oil smoke outlet 1.19B. During collision, oil mist adheres to the upper and lower side walls of the guide vanes. The invention prompts that in other embodiments, preferably, 2 to 6 bending points of the ventilation barrier can be selected.

Fig. 5 shows the preferred design parameters of the ventilation airway 1.15: 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. In the figure, the height of the flow guide grid is H, and the thickness is B. The design of the ventilation separation channel directly influences the ventilation effect, and under the condition that other parameters are not changed, the height H is reduced, the ventilation area of the inlet of the flow guide grid 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.

Fig. 4 shows that, in this example, the positioning members 1.11 for serial connection are the insertion pin 1.11A and the positioning hole 1.11B, and the positioning members 1.11 are arranged along the longitudinal direction with a gap. One side (upper side wall or lower side wall) of the flow guide sheet 1.1 is provided with a bolt 1.11A, a corresponding position on the other side is provided with a positioning hole 1.11B (positioning hole is socket with hole), and the flow guide sheets can be aligned, overlapped and connected in series with the fixing rib plates one by one up and down by inserting the bolt 1.11A into the positioning hole 1.11B.

The invention suggests that in the present example, the guide vane 1.1 should be injection molded, so the positioning member and the guide vane body can be integrally injection molded. The invention discloses an optimal scheme of the invention that a series connection positioning component is integrally arranged on a flow guide vane 1.1 in an injection molding manner, and aims to enable the flow guide vane to be more easily aligned and more conveniently connected in series when a flow guide grid is manufactured, and oil fume separators with different heights H can be formed by vertically stacking the flow guide vane according to requirements. The invention prompts that the plastic guide vane can be subjected to surface treatment, such as vacuum coating, spray coating and the like, so that the guide vane is easier to clean.

Fig. 6 and 7 are partial schematic structural views of a second embodiment of the present invention. Fig. 6 is a perspective view of a partial structure, and fig. 7 is an enlarged view of a partial structure. In the figure, unlike the first embodiment, the cross section of the flow guiding sheet 1.1 is further provided with a plurality of rib plates (such as 1.12A and 1.12B). The rib plates are arranged at intervals along the longitudinal direction, and the rib plates, the positioning members and the leaf body can be integrally formed by injection molding. The rib plate is used for enhancing the strength of the flow guide vane.

Fig. 8 and 9 are schematic structural views of a third embodiment of the present invention. Fig. 8 is a perspective view of the entire structure, and fig. 9 is an enlarged view of a part of the structure. In the figure, the guide grid 1 is shown to be composed of a combination of a left grid 1A and a right grid 1B, unlike the first embodiment. Fig. 9 is compared with fig. 3, in this example, the guide vane 1.1 has only one bending angle. The flow guide grid 1 is formed by combining a left grid 1A and a right grid 1B, and aims to reduce the overall size of the flow guide vane 1.1 and facilitate injection molding processing.

Fig. 10 and 11 are partial schematic structural views of a fourth embodiment of the present invention. Fig. 11 is a partially enlarged schematic view of the structure. In the figure, different from the third embodiment, in this example, the two ends of the left grille 1A are respectively provided with a sheath 1.110A and a sheath 1.110B (the right grille is similar in structure), and the sheaths are in a groove-shaped structure. In fig. 11, it is shown that the side walls 1.110A1 and 1.110A2 of the jacket 1.110A have wave-shaped curved surfaces matched with the adjacent guide vanes, and the jacket encloses and fixes the guide vanes which are overlapped and connected in series up and down. In this example, after the guide vanes are aligned and connected in series one by the positioning members 1.11, the jackets 1.110A and 1.110B can be easily wrapped at both ends of the left grill 1A. Because the guide vanes 1.1 are in a single bulk state before being connected in series, if the guide vanes are not connected in series and positioned by the positioning members, the guide vanes are difficult to align up and down one by one, and the jackets 1.110A and 1.110B are difficult to be included at two ends of the left grille 1A. In this example, the positioning member performs the alignment function, and the positioning member (between the pin and the positioning hole) does not need to be tightly fitted for easier disassembly; the sheath at the two ends plays a role in fixing. The flow guide grid can be disassembled easily only by disassembling the jackets at the two ends. The invention suggests that the groove-shaped sheath is only a preferable scheme of the invention, in other embodiments, the groove-shaped sheath can be replaced by a wrapping ring, and the wrapping ring can also have a telescopic function, such as a rubber ring.

Fig. 12 is a schematic structural diagram of a fifth embodiment of the present invention. In contrast to the first exemplary embodiment, the guide grid 1 has a rectangular four-sided frame structure (the longitudinal direction of the guide leaves forms a rectangular four-sided frame, and the guide leaves 1.1 have four bending corners).

Fig. 13 is an enlarged partial structural cross-sectional view (i.e., a schematic view of design parameters of a ventilation duct) illustrating a sixth embodiment of the present invention, wherein the direction of the arrow is a smoke flowing direction. In this example, the bending angles of the air flow ducts 1.15 become smaller in order according to the direction of the flow of the flue gas, as compared with fig. 5, unlike the first embodiment. In this example, the bending angle corresponding to the first bending point 1.18A is a1, the bending angle corresponding to the second bending point 1.18B is a2, the bending angle corresponding to the third bending point 1.18C is a3, the bending angle corresponding to the fourth bending point 1.18D is a4, and the angle values are a1 > a2 > a3 > a 4. In this example, the bending angles are sequentially decreased, so that the oil smoke separator can gradually capture oil mist particles with smaller and smaller particle sizes in the flowing process of oil smoke.

Fig. 14 and 15 are enlarged partial structures (the direction of an arrow in the figure is a smoke flow direction) of a seventh embodiment of the present invention, in which fig. 14 is an enlarged partial structure diagram, and fig. 15 is an enlarged partial structure cross-sectional diagram. In contrast to fig. 13, in this example, the upper side wall of the flow guide leaf 1.1 is also provided with longitudinal partitions 1.16a1, 1.16a2, 1.16A3 and the lower side wall is provided with longitudinal partitions 1.16B1, 1.16B2, in contrast to the sixth embodiment. In this case, the longitudinal partition is provided to further enhance the collision adhesion effect of the oil mist in the smoke. The invention suggests that in this example, the width-to-length ratio of the ventilation duct can be increased due to the longitudinal partition plate.

Fig. 16 is an enlarged view of a part of the structure of the eighth embodiment of the present invention. In contrast to fig. 14, in this example, the flow guide vanes 1.1 are also provided with through holes 1.17 arranged in a longitudinal direction, in contrast to the seventh exemplary embodiment. The through holes 1.17 enable the guide grid 1 to form oil leakage holes which are communicated up and down inside. The through holes 1.17 are arranged at the troughs 1.131, and the flow guide blades 1.1 are arranged horizontally (namely, the pages are in a horizontal state), so that oil stains adhered on the flow guide blades can drip down along the through holes 1.17 to be discharged out of the flow guide grid.

Fig. 17 is an enlarged partial structural cross-sectional view (the direction of the arrow in the figure is the direction of the flow of the smoke) of the ninth embodiment of the present invention. In contrast to fig. 15, in this example, the guide vanes 1.1 are of planar, straight-plate construction, in contrast to the seventh exemplary embodiment. The linear ventilation separation channel formed between the adjacent guide vanes 1.1 and 1.2 is divided into a repeatedly zigzag state by arranging a plurality of longitudinal clapboards.

The present invention suggests that the "level" mentioned in the present invention is not equal to the "level (0 degree)" in the mathematical concept, and is merely for explaining the technical content of the present invention, and the embodiment is not limited to the "level (0 degree)" in the mathematical sense. Moreover, the foregoing is only a few preferred embodiments of the present invention. In addition, according to the technical scheme provided by the invention, the cross section shape and the longitudinal structure of the flow guide blade, the structure of the positioning member, the sheath and the like can be correspondingly adjusted, so that more embodiments can be realized. All equivalents, modifications and improvements based on the technical solutions proposed by the present invention should be included in the scope of the present invention.
