Description

Technical Field

[0001] The utility model relates to a range hood accessory, in particular to a three-dimensional spliced ​​oil filter net for a range hood. Background Art

[0002] A range hood is a device used in the kitchen to absorb and purify oil fumes. One of its core components is the filter system. The design and efficiency of the filter directly affect the overall performance of the range hood, including its oil absorption and purification efficiency. Traditionally, the filters used in range hoods are mostly one-piece designs. Although this design has better structural stability and service life in some aspects, it also has obvious disadvantages and limitations.

[0003] One-piece filter screens are usually made of metal or high-density non-metallic materials that can withstand high temperatures and corrosive substances in the kitchen environment. However, this one-piece filter screen has extremely high material requirements during the manufacturing process, and special alloys or composite materials are required to ensure that its physical and chemical properties meet the needs of long-term use. This not only increases the material cost, but also increases the difficulty of processing.

[0004] The process of manufacturing one-piece filter is also relatively complicated. This filter needs to be completed through multiple processes such as high-precision mold pressing, cutting and bending, and each process requires special equipment and technical support. In addition, the high-precision processing requirements mean that the scrap rate in the production process is relatively high, which further increases the production cost. Due to these technical and cost considerations, the one-piece filter makes the final price of the product relatively high for consumers.

[0005] In addition to the cost issue, the design of the one-piece filter also limits its diversity in shape and size. Due to the high manufacturing cost of the mold, once the design is confirmed, subsequent modifications are very difficult and expensive. This limits the flexibility of product design and makes it difficult to optimize the filter according to different kitchen environments or user needs. At the same time, the heavy one-piece filter may also bring more difficulties to users during installation and replacement, so it is necessary to make further improvements to it. Utility Model Content

[0006] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a three-dimensional spliced ​​oil filter for a range hood that is simple in structure, easy to use, and conducive to reducing costs while improving the adaptability and user-friendliness of the product.

[0007] The purpose of the utility model is achieved in the following way: a three-dimensional spliced ​​oil filter net for a range hood, which includes two oppositely installed side nets and two oppositely installed end nets, the side walls of the side nets and the end nets are bent with connecting plates, and the adjacent side nets and end nets are butt-connected as a whole through the connecting plates to assemble an upwardly concave oil filter net main body.

[0008] Furthermore: the side net is in a trapezoidal shape that is wide at the top and narrow at the bottom, and the connecting plates are arranged on the two waistlines and the upper bottom of the side net.

[0009] Furthermore: the end net is in a triangular shape, and the connecting plates are arranged on two waist lines of the end net.

[0010] Furthermore: the connecting plate is arranged perpendicular to the main body of the side net or the main body of the end net.

[0011] Furthermore: after the end net and the side net are spliced ​​together, they are fixed into a whole by welding connecting plates.

[0012] Furthermore: after the end net and the side net are spliced ​​together, they are fixed as a whole by rivets arranged on the connecting plate.

[0013] Furthermore: after the end net and the side net are spliced ​​together, they are fixed as a whole by screws arranged on the connecting plate.

[0014] Furthermore, an air inlet groove is punched and extended from the main body of the end net and the side net toward the reverse side of the oil filter net, and the outer contour of the air inlet groove is folded inward to form an oil guide flange.

[0015] Furthermore, one end of the end net and the side net without the connection plate is a mounting edge, and an oil guide plate is extended upward from the mounting edge, and a covering plate is extended outward, and a plurality of oil leakage holes are opened on the oil guide plate.

[0016] Furthermore: the covering plate covers the oil collecting tank, the oil collecting tank is a rectangular frame structure, the upper end surface of the oil collecting tank is hollowed out to form an open slot, the covering plate covers the open slot and is fixed to the oil collecting tank as a whole.

[0017] The beneficial effects of the utility model are: 1. Simple structure, low production cost and improved market competitiveness.

[0018] 2. The three-dimensional spliced ​​oil filter for range hoods of the utility model adopts a method of splicing multiple components. Compared with the traditional one-piece filter, the size and shape of the filter can be flexibly adjusted according to actual needs. This modular design makes the product easier to adapt to range hoods of different models and sizes, and is convenient for storage and transportation.

[0019] 3. Due to the detachable splicing method, each component can be manufactured and replaced separately, reducing the cost of production and maintenance. In the production process, the manufacture of each component does not require complex molds, reducing manufacturing costs and scrap rates. In addition, users can only replace the damaged part instead of the entire filter, further reducing the cost of use.

[0020] 4. The design of the splicing structure simplifies the cleaning and maintenance process. Users can easily disassemble individual parts for detailed cleaning without disassembling the entire filter, which greatly improves the convenience of user operation and reduces maintenance time.

[0021] 5. By optimizing the side and end screens, such as trapezoidal and triangular designs, the aerodynamic characteristics are improved, so that the oil smoke can be guided and passed through the filter more effectively, thereby improving the absorption and purification efficiency of the oil smoke. The design of the air inlet slot and oil guide flange further optimizes the oil smoke flow path and enhances the overall performance of the range hood.

[0022] 6. The components are fixed by welding, rivets or screws to ensure the overall structural stability and durability of the filter. These connection methods provide good mechanical strength, ensuring that the filter remains stable in long-term use and maintains its shape and function even in high temperature and grease environments.

[0027] The utility model is further described in detail below with reference to the accompanying drawings. A three-dimensional spliced ​​oil filter for a range hood includes two oppositely mounted side nets 1 and two oppositely mounted end nets 2, the side walls of the side nets 1 and the end nets 2 are bent with connecting plates 3, and the adjacent side nets 1 and end nets 2 are connected to form a whole by connecting plates 3, so as to assemble an upwardly concave oil filter body.

[0028] In one embodiment, the side net 1 is in a trapezoidal shape that is wide at the top and narrow at the bottom, and the connecting plates 3 are arranged on the two waistlines and the upper bottom of the side net 1.

[0029] In one of the embodiments: the end net 2 is in a triangular shape, and the connecting plate 3 is arranged on the end net 2. In one of the embodiments: the connecting plate 3 is arranged perpendicular to the main body of the side net 1 or the main body of the end net 2.

[0030] In one embodiment, the end net 2 and the side net 1 are spliced ​​and fixed into a whole by welding the connecting plate 3.

[0031] In one embodiment, after the end net 2 and the side net 1 are spliced ​​together, they are fixed as a whole by rivets arranged on the connecting plate 3.

[0032] In one embodiment, after the end net 2 and the side net 1 are spliced ​​together, they are fixed into a whole by screws arranged on the connecting plate 3.

[0033] In one embodiment, the main bodies of the end net 2 and the side net 1 are punched and extended with air inlet grooves 4 in the reverse direction to the reverse side of the oil filter net, and the outer contour of the air inlet grooves 4 is folded inward to form oil guide flanges 5.

[0034] In one embodiment, the end of the end net 2 and the side net 1 where the connecting plate 3 is not provided is a mounting edge, and an oil guide plate 6 is extended upward from the mounting edge, and a covering plate 7 is extended outward, and a plurality of oil leakage holes 8 are opened on the oil guide plate 6.

[0035] In one embodiment, the cover plate 7 covers the oil collecting tank 10, and the oil collecting tank 10 is in a rectangular frame structure. The upper end surface of the oil collecting tank 10 is hollowed out to form an open groove. The cover plate 7 covers the open groove and is fixed to the oil collecting tank 10 as a whole.

[0036] Working principle: In this case, the three-dimensional spliced ​​oil filter for the range hood includes two oppositely mounted side nets 1 and two oppositely mounted end nets 2, which adopt a trapezoidal and triangular design. This design not only allows the product to better adapt to different models of range hoods, but also allows customization of size and shape, enhancing the flexibility of the design. The side net 1 and the end net 2 form a connecting plate 3 through the bent side wall, which is used to achieve a stable docking connection.

[0037] During the assembly process, by using modular components, each part can be manufactured and replaced separately, which not only reduces production costs but also simplifies the maintenance process. Users can replace only the damaged part without having to replace the entire filter, further reducing long-term use costs.

[0038] It should be noted that the concave structure design of the filter slows down the flow rate of oil smoke when passing through the filter, increasing the contact time between the oil smoke and the filter, thereby improving the absorption efficiency of the oil smoke. This structure effectively expands the surface area of ​​contact between the oil smoke and the filter, improving the performance of oil smoke purification.

[0039] It should be noted that the design of the air inlet slot 4 and the oil guide flange 5 optimizes the air flow, so that the oil smoke can be effectively guided to the oil collection tank after hitting the filter, reducing the escape of oil smoke. This design not only improves the purification efficiency of oil smoke, but also enhances the overall performance of the range hood.

[0040] It should be noted that the structure of the filter is fixed by welding, rivets or screws. This multi-point fixing technology ensures the overall structural stability and durability of the filter. This structural design not only provides sufficient mechanical strength to resist vibration and thermal expansion in the kitchen environment. When using screws to fix, it also makes it easier to disassemble and clean the filter, supporting efficient maintenance.

[0041] Compared with traditional technologies, the modular and detachable design in this case facilitates recycling and reuse, which meets the needs of modern environmental protection and sustainable development. This design reduces the overall generation of waste, helps promote the development of kitchen equipment in a more environmentally friendly direction, and can effectively improve the market competitiveness of products.

[0042] Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the scope of protection of the claims created by the utility model.
