Description

Technical Field

[0001] This utility model relates to the technical field of range hoods, and in particular to an oil mesh structure and a range hood. Background Technology

[0002] In existing near-suction range hoods, the oil mesh structure is often used to filter oil fumes and regulate the air intake; among them, the manually adjustable oil mesh structure mainly relies on the relative sliding of the inner and outer oil meshes to realize the opening and closing function of the air intake.

[0003] However, in this type of structure, oil droplets tend to accumulate in the gap between the adjustment handle and the handle hole, and cannot flow into the oil cup effectively. After long-term use, oil stains will accumulate in the above-mentioned gap position or even between the inner and outer oil mesh, which will cause the inner oil mesh to slide and get stuck, affecting the normal use of the opening and closing adjustment function. Utility Model Content

[0004] Therefore, it is necessary to provide an oil mesh structure and range hood that can effectively prevent oil buildup, addressing the problem that long-term use of current oil-stained structures can lead to sliding and jamming.

[0005] This application provides an oil mesh structure, including an oil cup, an outer oil mesh and an inner oil mesh stacked along a first direction, wherein the inner oil mesh is slidably connected to the back of the outer oil mesh along a second direction to have an open and a closed state, wherein, in the open state, the first ventilation hole on the inner oil mesh is directly opposite to the second ventilation hole on the outer oil mesh; in the closed state, the inner oil mesh is misaligned and blocks the second ventilation hole;

[0006] The oil cup is fixed relative to the outer oil mesh and located at the bottom of the outer oil mesh. A first oil guiding surface is formed between each adjacent second ventilation hole of the outer oil mesh, which can guide oil to the oil cup.

[0007] The outer oil mesh has a through hole at the top of the second ventilation hole, and the inner oil mesh has a handle that passes through the through hole and protrudes from the outer oil mesh. The inner wall of the through hole forms a second oil guiding surface that can guide oil to the first oil guiding surface.

[0008] In one embodiment, the inner wall of the clearance hole is divided into a first inner wall and a second inner wall along a third direction. The first inner wall is located on the side close to the oil cup and forms a second oil guiding surface. The projection of the second oil guiding surface along a third direction covers the entire clearance hole, and the lowest point of the bottom of the second oil guiding surface is directly opposite one of the first oil guiding surfaces along a third direction.

[0009] In one embodiment, the second inner wall is formed with a third oil guiding surface, the projection of the third oil guiding surface along a third direction covers the entire clearance hole, and the third oil guiding surface can guide oil stains to the second oil guiding surface.

[0010] In one embodiment, the clearance hole is elliptical, and both the second oil guiding surface and the third oil guiding surface are arc-shaped.

[0011] In one embodiment, the projection of the handle along the first direction is completely located within the clearance hole, and the surface of the handle forms a fourth oil guiding surface capable of guiding oil stains to the second oil guiding surface.

[0012] In one embodiment, the height of the handle gradually decreases towards the oil cup along the first direction to form the fourth oil guiding surface.

[0013] In one embodiment, in the open state, at least a portion of the fourth oil-guiding surface is in contact with the second oil-guiding surface.

[0014] In one embodiment, the height of the second ventilation hole corresponding to the clearance hole along a third direction is lower than the height of the other second ventilation holes, and the top edge of the clearance hole is flush with the top edge of the other second ventilation holes.

[0015] In one embodiment, the second oil guiding surface has a rounded corner on the side away from the inner oil mesh along the first direction.

[0016] This application also provides a range hood, including a range hood body and the aforementioned oil mesh structure, wherein the outer oil mesh is fixed to the inner wall of the air intake of the range hood body.

[0017] The aforementioned oil mesh structure, through the coordinated design of the first oil guiding surface on the outer oil mesh surface and the second oil guiding surface inside the clearance hole, transforms the sliding area between the clearance hole and the inner oil mesh, which was originally prone to oil accumulation, into an oil sludge guiding channel, thus avoiding the situation where the inner oil mesh gets stuck due to oil sludge accumulation. At the same time, by utilizing the hierarchical oil guiding path of the second oil guiding surface, the first oil guiding surface, and the oil cup, oil sludge collection with full structural coverage is achieved, taking into account both the functionality of opening and closing adjustment and the self-cleaning ability.

[0032] Please combine Figure 1 , Figure 2 , Figure 3 as well as Figure 4As shown, this application provides an oil mesh structure, including an oil cup 10, an outer oil mesh 20 and an inner oil mesh 30 stacked along a first direction. The inner oil mesh 30 is slidably connected to the back of the outer oil mesh 20 along a second direction, so as to have an open and closed state. In the open state, the first ventilation hole 31 on the inner oil mesh 30 is directly opposite to the second ventilation hole 21 on the outer oil mesh 20. In the closed state, the inner oil mesh 30 is offset and blocks the second ventilation hole 21. The oil cup 10 is fixed relative to the outer oil mesh 20 and is located at the bottom of the outer oil mesh 20. A first oil guiding surface 22 is formed between each adjacent second ventilation hole 21 of the outer oil mesh 20, which can guide oil to the oil cup 10. The outer oil mesh 20 is provided with a clearance hole 23 located at the top of the second ventilation hole 21. The inner oil mesh 30 is fixed with a handle 32 that passes through the clearance hole 23 and protrudes from the outer oil mesh 20. The inner wall of the clearance hole 23 is formed with a second oil guiding surface 231, which can guide oil to the first oil guiding surface 22.

[0033] Through the coordinated design of the first oil guiding surface 22 on the surface of the outer oil mesh 20 and the second oil guiding surface 231 inside the clearance hole 23, the sliding area between the clearance hole 23 and the inner oil mesh 30, which was originally prone to oil accumulation, is transformed into an oil sludge guiding channel, avoiding the situation where the inner oil mesh 30 gets stuck due to oil sludge accumulation; at the same time, by utilizing the hierarchical oil guiding path of the second oil guiding surface 231, the first oil guiding surface 22 and the oil cup 10, oil sludge collection with full structural coverage is achieved, taking into account both the functionality of opening and closing adjustment and the self-cleaning ability.

[0034] Specifically, the inner oil screen 30 slides along the second direction, and the air volume is adjusted (open / closed state) by aligning or misaligning the first ventilation hole 31 with the second ventilation hole 21; the clearance hole 23 passes through the top of the outer oil screen 20, providing sliding space for the handle 32, and at the same time, the second oil guiding surface 231 on its inner wall guides the oil in the area inside the clearance hole 23 to the first oil guiding surface 22, avoiding oil from stagnating on the sliding path and ensuring that the inner oil screen 30 opens and closes smoothly.

[0035] More specifically, the second oil guiding surface 231 is designed as an inclined or arc-shaped surface to collect oil droplets attached to the inner wall of the clearance hole 23 and sliding off the handle 32, and guide them to the first oil guiding surface 22 of the outer oil mesh 20, so as to prevent oil from accumulating at the clearance hole 23; multiple first oil guiding surfaces 22 are formed between each adjacent second ventilation hole of the outer oil mesh 20, and the first oil guiding surfaces 22 extend in the third direction, using gravity to guide the oil to the oil cup 10 at the bottom.

[0036] In some embodiments, the first oil guiding surface 22 may also be formed into a downwardly inclined slope or groove to optimize oil guiding efficiency.

[0037] In some embodiments, the handle 32 is integrally formed by stamping the inner oil mesh 30 outwards or is fixed to the outer surface of the inner oil mesh 30 by welding, bolting, or other methods. Examples are not listed here. Preferably, the handle 32 is integrally formed by stamping the inner oil mesh 30 outwards to reduce production difficulty and cost.

[0038] Please refer to Figure 2 As shown, in some embodiments, the inner wall of the clearance hole 23 is divided into a first inner wall and a second inner wall along a third direction. The first inner wall is located on the side near the oil cup 10 and forms a second oil guiding surface 231. The projection of the second oil guiding surface 231 along the third direction covers the entire clearance hole 23, and the lowest point of the bottom of the second oil guiding surface 231 is directly opposite one of the first oil guiding surfaces 22 along the third direction.

[0039] It is understandable that by dividing the inner wall of the clearance hole 23 into a first inner wall (near the oil cup 10) and a second inner wall, and by defining that the lowest point of the bottom of the second oil guiding surface 231 is directly opposite to the first oil guiding surface 22, vertical oil guiding can be achieved by using gravity, ensuring that the oil flows directly from the clearance hole 23 to the first oil guiding surface 22 of the outer oil mesh 20, avoiding leakage caused by lateral displacement of the oil, thereby achieving precise oil guiding and positioning;

[0040] Furthermore, by limiting the projection of the second oil guiding surface 231 along a third direction to cover the entire clearance hole 23, it can be ensured that oil stains in all areas of the clearance hole 23 can be guided without any dead corners.

[0041] Please refer to Figure 2 As shown, in some embodiments, a third oil guiding surface 232 is formed on the second inner wall. The projection of the third oil guiding surface 232 along a third direction covers the entire clearance hole 23, and the third oil guiding surface 232 can guide the oil stains to the second oil guiding surface 231.

[0042] It is understandable that if the second inner wall of the clearance hole 23 (the side away from the oil cup 10) does not have an oil guiding design, oil may stagnate in the area or flow along a non-preset path. In this regard, this application has discussed forming a third oil guiding surface 232 on the second inner wall, so that it forms a continuous oil guiding path with the second oil guiding surface 231, covering the entire inner wall surface of the clearance hole 23, thereby forming a full-circumference oil guiding surface inside the clearance hole 23.

[0043] Specifically, since the second inner wall is located on top of the first inner wall, the oil on the second inner wall can be actively guided by the third oil guiding surface 232 to the second oil guiding surface 231 under the action of gravity, and then flow to the first oil guiding surface 22, forming a closed-loop flow.

[0044] In addition, by limiting the projection of the third oil guiding surface 232 along the third direction to cover the entire clearance hole 23, the effect of reducing oil residue can also be achieved.

[0045] Please refer toFigure 2 As shown, in some embodiments, the clearance hole 23 is elliptical, and the second oil guiding surface 231 and the third oil guiding surface 232 are both arc-shaped.

[0046] Traditional clearance holes 23 are mostly rectangular, which cannot adapt to the flow characteristics of oil, resulting in greater oil flow resistance and easy oil accumulation. In this application, the elliptical clearance hole 23 and the arc-shaped second oil guiding surface 231 and third oil guiding surface 232 are more in line with the surface tension characteristics of oil, which can reduce the resistance of oil droplet adhesion and improve the oil guiding efficiency.

[0047] Specifically, the second oil guiding surface 231 and the third oil guiding surface 232 utilize the continuity of the arc-shaped surface to allow oil to flow naturally along the arc direction, reducing oil droplet residue caused by right-angled edges.

[0048] More specifically, the major axis of the ellipse is parallel to the second direction, and the minor axis is parallel to the third direction.

[0049] Please refer to Figure 2 As shown, in some embodiments, the projection of the handle 32 along the first direction is completely located within the clearance hole 23, and the surface of the handle 32 is formed with a fourth oil guiding surface 321 that can guide oil stains to the second oil guiding surface 231.

[0050] The fourth oil guiding surface 321 on the surface of the handle 32 actively guides the oil to the second oil guiding surface 231 on the inner wall of the clearance hole 23, preventing the oil from accumulating on the surface of the handle 32 or in the sliding gap. In addition, by limiting the projection of the handle 32 along the first direction to be completely within the clearance hole 23, it is ensured that the second oil guiding surface 231 can receive all the oil dripping from the handle 32, preventing the oil from dripping into areas outside the oil guiding path.

[0051] Please refer to Figure 2 As shown, in some embodiments, the handle 32 gradually decreases in height towards the oil cup 10 along the first direction to form a fourth oil guiding surface 321, thereby using gravity to allow the oil droplets to slide naturally towards the second oil guiding surface 231, achieving rapid drainage; compared with structures such as opening oil guiding grooves, the inclined fourth oil guiding surface 321 has a simple structure, which can reduce costs and improve reliability.

[0052] Specifically, the angle of the fourth oil guide surface 321 is adapted to the viscosity and surface tension of the oil. As long as the oil can be prevented from being stuck on the surface of the handle 32 due to flow resistance, this application does not make any further limitations.

[0053] In some embodiments, the top of the handle 32 is arc-shaped to prevent oil from accumulating on the top of the handle 32.

[0054] Please refer to Figure 2As shown, in some embodiments, in the open state, at least part of the fourth oil guiding surface 321 is in contact with the second oil guiding surface 231.

[0055] It is understandable that when the inner oil filter 30 is open, the amount of oil smoke is relatively large, and the amount of oil adhering to the handle 32 is also relatively large. However, through the contact between the fourth oil guide surface 321 and the second oil guide surface 231, the oil is directly transferred through the contact surface between the two, which can effectively prevent the oil from dripping or even splashing in the middle.

[0056] In addition, the contact surfaces of the two can serve as both oil guiding channels and form a dynamic seal to prevent oil from seeping into the gap between the inner oil mesh 30 and the outer oil mesh 20, thus preventing oil accumulation.

[0057] Please combine Figure 1 as well as Figure 3 As shown, in some embodiments, the height of the second ventilation hole 21 corresponding to the clearance hole 23 along a third direction is lower than the height of the other second ventilation holes 21, and the top edge of the clearance hole 23 is flush with the top edge of the other second ventilation holes 21.

[0058] Please refer to Figure 2 As shown, in some embodiments, the second oil guiding surface 231 has a rounded corner on the side away from the inner oil mesh 30 along the first direction to reduce the adhesion of oil droplets at the edge of the second oil guiding surface 231, ensuring that the oil droplets can flow smoothly to the first oil guiding surface 22 and avoid oil accumulation.

[0059] Furthermore, the edges of the third oil guiding surface 232, the fourth oil guiding surface 321, and the second ventilation hole 21 are all rounded, which can also prevent oil accumulation.

[0060] Please combine Figure 3 , Figure 5 as well as Figure 6 As shown, in some embodiments, the oil mesh structure further includes at least two sets of magnetic assemblies 40. Each set of magnetic assemblies 40 includes a magnet 41 and a first support member 42. The first support member 42 includes a support portion 421 and a limiting post 422. The front of the support portion 421 forms a point contact with the outer oil mesh 20 and the back forms a receiving cavity. The limiting post 422 is fixed to the bottom wall of the receiving cavity. The magnet 41 is sleeved on the limiting post 422 and located in the receiving cavity. The front of the inner oil mesh 30 has a plurality of grooves 33 corresponding to the magnetic assemblies 40. The support portion 421 is embedded in the corresponding groove 33. The limiting post 422 penetrates the through hole in the bottom wall of the groove 33.

[0061] Specifically, after the magnet 41 is inserted into the limiting post 422, it is magnetically attracted to the groove 33. The limiting post 422 is inserted into the through hole in the bottom wall of the groove 33 to form a radial rigid limit. The magnet 41 is also magnetically attracted to the outer oil mesh 20 to improve the connection stability between the inner oil mesh 30 and the outer oil mesh 20 along the first direction. In addition, the contact area between the front of the support part 421 and the outer oil mesh 20 is only a point to greatly reduce the sliding resistance.

[0062] The point contact design can effectively reduce the sliding friction resistance between the outer oil mesh 20 and the support part 421, thus making it smoother for the user to adjust the inner oil mesh 30 through the handle 32.

[0063] In some embodiments, the front of the support portion 421 is designed as a spherical surface, and the depth of the groove 33 along the first direction is slightly less than the thickness of the support portion 421 along the first direction, so that the support portion 421 can partially protrude from the front of the inner oil mesh 30 and form point contact with the back of the outer oil mesh 20.

[0064] Furthermore, in some embodiments, the oil mesh structure is provided with four sets of magnetic attraction components 40, which are correspondingly embedded in the four grooves 33 at the four corners of the inner oil mesh 30.

[0065] Furthermore, the magnets 41 of the two sets of magnetic attraction components 40 located on the upper side are larger in volume than the magnets 41 of the two sets of magnetic attraction components 40 located on the lower side.

[0066] Please refer to Figure 5 As shown, in some embodiments, the edges of both the inner oil mesh 30 and the outer oil mesh 20 are provided with flanges that bend towards the back.

[0067] Specifically, the inner oil mesh 30 and the outer oil mesh 20 are connected by a flange along a third direction. Through the flange design of the inner oil mesh 30 and the outer oil mesh 20, the overall rigidity of the oil mesh structure is improved, while also constraining the sliding direction and stabilizing the gap size, ensuring the smoothness of the inner oil mesh 30 sliding along the second direction.

[0068] Please refer to Figure 5 As shown, in some embodiments, the outer oil mesh 20 has a second support member 24 protruding inward on the flange along a third direction, and the second support member 24 makes point contact with the flange of the inner oil mesh 30.

[0069] Traditional flanged structures, which slide through surface contact (such as direct contact of the entire flange), tend to have an excessively large friction area, resulting in a large starting torque and requiring more effort from the user. In contrast, this application adds a second support member 24 to the flanges on both sides of the outer oil mesh 20 along the third direction, which reduces the contact area while providing multi-point local support, thus balancing the conflict between rigidity enhancement and frictional resistance reduction.

[0070] Specifically, the second support member 24 can be hemispherical, curved, or other shapes, as long as it can make point contact with the flange of the inner oil mesh 30. Each flange of the outer oil mesh 20 is provided with 3 to 5 equally spaced second support members 24. This ensures both uniform support and minimizes friction. Even if one second support member 24 fails due to wear, the remaining second support members 24 can still maintain the positioning and support of the inner oil mesh 30, extending its service life. Preferably, each flange of the outer oil mesh 20 is provided with 4 equally spaced second support members 24.

[0071] Please refer to Figure 5 As shown, the outer oil mesh 20 has a secondary flange along the bottom edge of the third direction. When it is necessary to remove the inner oil mesh 30 and the outer oil mesh 20, first use the bottom flange of the outer oil mesh 20 as the rotation center, and then rotate the top of the inner oil mesh 30 to the back side to remove the inner oil mesh 30. During this process, the secondary flange at the bottom of the outer oil mesh 20 can play a supporting role, so as to facilitate the removal of the inner oil mesh 30 and the outer oil mesh 20 and their separate cleaning.

[0072] The assembly process is the reverse of the disassembly process, and will not be described in detail here.

[0073] Please refer to Figure 5 As shown, in some embodiments, the flanges of the outer oil mesh 20 and the inner oil mesh 30 are kept as straight as possible. Preferably, the flange of the inner oil mesh 30 is a continuous, unbroken ring to improve the rigidity of the outer oil mesh 20 and the inner oil mesh 30, and to effectively reduce the gap between the inner oil mesh 30 and the outer oil mesh 20 compared to cases with more breaks.

[0074] Please refer to Figure 4 As shown, this application also provides a range hood, including a range hood body and the aforementioned oil mesh structure, wherein the outer oil mesh 20 is fixed to the inner wall of the air intake of the range hood body.

[0075] Specifically, two sets of oil mesh structures are provided inside the smoke inlet along the second direction.

[0076] Please combine Figure 2 as well as Figure 5 As shown, the outer oil mesh 20 is also fixed with a latch 50 located on the upper side of the clearance hole 23 along the third direction, which is used to snap and fix it to the range hood body.

[0077] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0078] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
