Detailed Implementation

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0023] The first aspect of this utility model provides a lower panel assembly, such as... Figure 1 and Figure 2 As shown, it includes a baffle plate 4, which includes a baffle 41 and a baffle 42 with an integral structure. The baffle 42 is provided with an air inlet 421, and the edge of the air inlet 421 is provided with a connection hole 4221 for connecting with the exhaust mechanism.

[0024] When installing the baffle plate 4, simply connect the baffle plate 41 to the outer casing assembly 5 of the range hood, and then connect the baffle plate to the exhaust mechanism by passing screws or other fasteners through the connecting holes 4221. This structure eliminates the assembly process between the baffle plate 41 and the baffle ring 42 in the traditional structure, effectively shortening the installation time and avoiding problems such as component misalignment or insufficient connection strength caused by improper assembly operations.

[0025] The baffle 41 and the retaining ring 42 can be manufactured by stamping, bending and other processes, without welding or splicing seams, which improves the structural strength and sealing performance, while also facilitating mass production and reducing assembly costs.

[0026] In an optional embodiment, the baffle 41 has an outer side facing the cooktop and an inner side facing away from the cooktop. On the outer side, the baffle 41 faces the cooking area, providing some shielding; on the inner side, it faces the volute in the exhaust mechanism inside the range hood, and the volute has threaded holes that are aligned one-to-one with the connecting hole 4221. During installation, screws can be passed through the connecting hole 4221 and tightened into the threaded holes of the volute to connect the retaining ring 42 to the volute.

[0027] like Figure 1 As shown, the baffle 41 can be flipped up to a certain height around its perimeter, and a certain number of fixing holes 411 are distributed on each of the flipped edges. The baffle 41 is fastened to the outer casing assembly 5 in the range hood by using screws to pass through the fixing holes 411.

[0028] The baffle ring 42 is arranged around the outer circumference of the exhaust mechanism. It has an air inlet 421, which corresponds to the air inlet end of the impeller in the exhaust mechanism, allowing external oily fumes to enter the impeller cavity radially or axially, so as to achieve efficient suction and exhaust.

[0029] In alternative implementations, such as Figure 2 As shown, the outer edge of the baffle ring 42, away from the air inlet 421, protrudes outward toward the baffle plate 41, forming an outwardly protruding structure 422. This outwardly protruding structure 422 extends circumferentially along the baffle ring 42 and is provided with at least one connecting hole 4221 for alignment and mating with the docking hole 22 on the safety net assembly.

[0030] When the safety net assembly is installed, the mating hole 22 on the connector 2 is aligned with the connecting hole 4221. Fasteners (such as screws, rivets or self-tapping screws) pass through the mating hole 22 and the connecting hole 4221 and are screwed into the ventilation mechanism, thereby realizing the connection between the safety net assembly, the baffle plate 4 and the ventilation mechanism.

[0031] In addition, such as Figure 2 As shown, the inner edge of the baffle ring 42 near the air inlet 421 is recessed towards the inner side of the baffle 41, forming an inwardly recessed structure 423. This recessed structure 423 can smoothly transition along the impeller edge, forming a guide surface. On the one hand, it can effectively block splashing oil droplets when the impeller rotates at high speed; on the other hand, it can guide the gas flow, reduce eddy current losses, and improve exhaust efficiency.

[0032] In alternative implementations, such as Figure 2 As shown, the retaining ring plate 4 also includes an oil guiding structure 43 located at least on the retaining plate 41 and the outward convex structure 422.

[0033] The aforementioned oil guiding structure 43 can be integrally formed on the baffle plate 4, extending radially along the air inlet 421 and at least located in the area where the baffle plate 41 and the outwardly convex structure 422 are located. When its extension length is long, it can also extend to the inwardly concave structure 423. The oil guiding structure 43 is recessed towards the inner side of the baffle plate 41 and is provided with an oil leakage channel 431, so that the oil accumulated in the oil guiding structure 43 can be discharged downward to the oil collection structure of the range hood by gravity.

[0034] Furthermore, the depth of the oil guiding structure 43 recessed towards the inside of the baffle 41 is less than the depth of the recessed structure 423 recessed towards the inside of the baffle 41, so that the oil guiding structure 43 can effectively drain the oil stains inside the baffle plate 4.

[0035] In alternative implementations, such as Figure 1 As shown, the lower panel assembly also includes a safety net assembly located at the air inlet 421, the safety net assembly having an opening 113 configured to allow airflow and prevent fingers from passing through.

[0036] The above-mentioned opening 113 is configured in multiple ways, and its size design needs to meet the safety protection requirements, ensuring that the user's fingers cannot pass through, effectively preventing contact with the internal exhaust mechanism, while ensuring sufficient air intake area, so as not to affect the range hood's oil fume extraction performance. The following sections will illustrate the size of the opening 113 with examples based on the specific structure of the safety net component.

[0037] In addition, the safety net assembly can be integrated with the retaining ring 42.

[0038] For example, the safety net components are formed on the retaining ring plate 4 in one step through stamping, injection molding or die casting processes, and the functions can be integrated without additional assembly steps.

[0039] In the above embodiments, since the safety net assembly, baffle 41 and retaining ring 42 are integrated structures, not only is the number of parts and assembly process required to install each structure separately in the traditional solution reduced, but also problems such as positioning deviation, loosening and falling off caused by secondary assembly are avoided, thereby improving the overall structure and mechanical strength.

[0040] Of course, the safety net assembly can also be detachably connected to the retaining ring 42 to facilitate cleaning of the safety net assembly.

[0041] In an optional embodiment, the safety net assembly includes an outer ring structure 11 and an inner disc 12. The outer ring structure 11 is arranged around the outer side of the inner disc 12 and has an opening 113. The outer ring structure 11 extends gradually from the inner edge to the outer edge toward one side of the axial direction of the inner disc 12, so that the outer edge of the outer ring structure 11 is located on one side of the inner disc 12.

[0042] In the assembled state, the outer edge of the outer ring structure 11 is offset relative to the inner disk 12 along its axial direction, for example, located above the inner disk 12, so that the outer ring structure 11 gradually converges towards the inner disk 12 from top to bottom.

[0043] The above arrangement helps to form a guide slope between the outer ring structure 11 and the inner disk 12. Under the action of gravity, the oil can be concentrated and guided from the outer ring structure 11 to the inner disk 12, which is conducive to the centralized collection of oil.

[0044] Specifically, along the axial direction of the inner disk 12, the distance between the outer edge of the outer ring structure 11 and the inner disk 12 can be 7mm.

[0045] In alternative implementations, such as Figure 3 As shown, the safety net assembly also includes a first oil cup 3 for collecting condensed oil droplets or other liquid contaminants generated during cooking. The inner plate 12 is provided with a mounting hole 121 for connecting to the first oil cup 3, which is located along the axial direction of the inner plate 12 on the side of the inner plate 12 opposite to the outer edge of the outer ring structure 11.

[0046] When in use, the outer edge of the outer ring structure 11 is located on the upper side of the inner plate 12, and the first oil cup 3 is installed on the lower side of the inner plate 12, close to the stove. The oil stains gathered on the inner plate 12 can enter the first oil cup 3 through the hole in the middle of the inner plate 12 for collection, effectively preventing oil stains from dripping directly from the safety net body 1.

[0047] The aforementioned mounting hole 121 may include an insertion hole and a snap-fit ​​hole communicating with the insertion hole. The insertion hole is larger in size, and the snap-fit ​​hole extends in an arc shape with the axis of the inner disk 12 as its axis. When installing the first oil cup 3, the retaining pin on the first oil cup 3 can first extend into the insertion hole, and then rotate the first oil cup 3 along the extension direction of the snap-fit ​​hole. Under the limitation of the snap-fit ​​hole, the retaining pin on the first oil cup 3 is locked inside the first oil cup 3. Depending on the connection method between the safety net component and the retaining ring 42, the following two embodiments can be implemented: Example 1: In this first embodiment, the outer ring structure 11 and the inner disk 12 adopt an integral structure. The outer ring structure 11 and the inner disk 12 can be manufactured by integral stamping, integral injection molding, etc., without splicing, welding or riveting and other connecting structures between them, thus forming a complete and continuous whole.

[0048] The aforementioned integrated structure not only improves the overall structural strength and rigidity of the safety net body 1, but also avoids problems such as loose connections, deformation, or stress concentration caused by the assembly of multiple components, thereby enhancing the stability and durability of the safety net components during long-term use.

[0049] Specifically, multiple openings 113 are evenly distributed and formed on the outer ring structure 11. Specifically, each opening 113 is arranged at equal intervals along the circumference of the outer ring structure 11, forming a regularly arranged array of through holes. The openings 113 can be arranged in a single row or multiple rows along the direction from the inner edge to the outer edge of the outer ring structure 11 to further optimize airflow distribution or enhance structural rigidity.

[0050] The shape of the opening 113 can be circular, polygonal, or other irregular.

[0051] by Figure 5 For example, the openings 113 are arranged in multiple rows along the inner edge of the outer ring structure 11 towards the outer edge, with each row staggered. The openings 113 are hexagonal in shape, thus forming a honeycomb structure. This structural design can effectively reduce the noise and vibration of the range hood and prevent users' fingers from entering the impeller of the range hood and causing injury.

[0052] Specifically, the diagonal length of the opening 113 is no greater than 9.5mm, and the spacing between the openings 113 is 1.5mm.

[0053] Example 2: In this second embodiment, the safety net assembly and the retaining ring 42 are detachably connected. For example... Figure 5 As shown, the safety net assembly may include connectors 2, and multiple connectors 2 are distributed circumferentially along the safety net body 1. Each connector 2 includes an extension 21 extending outward from the edge of the safety net body 1, and the extension 21 is bent from the outside to the inside to form a mating hole 22.

[0054] like Figure 6 and Figure 7 As shown, during installation, the aforementioned mating hole 22 can be directly aligned with the connecting hole 4221, and the safety net assembly can be installed using screws or other structures. The aforementioned safety net assembly makes the installation location between the safety net assembly and the range hood more prominent, reducing user viewing distance and facilitating installation.

[0055] Furthermore, since the extension 21 of the connector 2 extends beyond the safety net body 1, the diameter of the safety net body 1 is reduced, making it easier for the user to observe the position of the extension 21 during installation. Because the extension 21 is bent directly from the outside in to form the mating hole 22, its structure is simple, and the bending process can be completed using a simple bending tool without the need for additional parts, resulting in a simple structure and convenient processing.

[0056] like Figure 5As shown, the outer ring structure 11 includes a ring body 111 and a plurality of blocking members 112; the ring body 111 is sleeved on the outside of the inner disk 12 and spaced apart from the inner disk 12; the plurality of blocking members 112 are evenly spaced along the circumference of the inner disk 12, one end of each blocking member 112 is connected to the ring body 111 and the other end is connected to the inner disk 12, and an opening 113 is formed between two adjacent blocking members 112, and the openings 113 are arranged in a single row along the direction from the inner edge to the outer edge of the outer ring structure 11.

[0057] The aforementioned blocking element 112 not only serves to connect the ring body 111 and the inner disk 12, but also acts as a physical barrier for safety protection. Together with the ring body 111 and the inner disk 12, it defines the regularly distributed openings 113, so that the overall outer ring structure 11 has the triple functions of mechanical support, air flow guidance and mechanical protection.

[0058] In order to facilitate the processing of the safety net body 1, the ring 111 can be a metal ring, specifically an iron ring, and the blocking component 112 can be a metal strip, specifically an iron strip.

[0059] In this second embodiment, the connector 2 also includes a connecting section 23 connecting the ring 111 and the inner disk 12. The connecting section 23 and the outer extension section 21 adopt an integral structure. For example, the connector 2 can be a metal strip, and its end away from the inner disk 12 is bent from the outside to the inside to form a mating hole 22. Specifically, the connector 2 can be an iron strip.

[0060] Based on the above embodiment, the connecting segment 23 is located between any two adjacent blocking members 112, and forms an opening 113 with each of the two adjacent blocking members 112.

[0061] In other words, the gap space naturally formed between the two adjacent blocking members 112, the ring body 111, and the inner plate 12 remains open as a ventilation channel after the introduction of the connecting section 23. The gap is divided into two openings 113 by the connecting section 23, which can reduce the use of the blocking members 112 to a certain extent.

[0062] In this second embodiment, the connector 2 integrates the connecting section 23 and the extension section 21 into one unit, which not only enhances the connection stability between the ring 111 and the inner disk 12, but also serves to form the opening 113, reducing the use of the blocking component 112. In addition, fixing the connecting section 23 can simultaneously fix the position of the mating hole 22, eliminating the need to open a new mold for the connecting parts to form the connecting structure, reducing assembly process steps, and lowering manufacturing costs.

[0063] In this second embodiment, the ring 111 is provided with a plurality of first grooves, the inner plate 12 is provided with second grooves that cooperate with the first grooves one by one, and the two ends of the connecting section 23 and the blocking member 112 are respectively connected to the cooperating first grooves and second grooves.

[0064] The first groove is recessed into the axial end face of the ring 111, and its position and number correspond to the arrangement positions of the connecting section 23 and the blocking member 112, and are evenly distributed along the circumference of the ring 111. Correspondingly, in the outer peripheral region of the inner disk 12, a second groove is provided at the position of each first groove, and the second groove is recessed into the axial end face of the inner disk 12.

[0065] During assembly, one end of the connecting section 23 is embedded in the first groove on the ring 111, and the other end is embedded in the second groove on the inner plate 12, and the connection is fixed by welding. Similarly, one end of the blocking member 112 is embedded in the first groove on the ring 111, and the other end is embedded in the second groove on the inner plate 12, and the connection is fixed by welding.

[0066] In this second embodiment, by fixing the two ends of the connecting segment 23 into the first and second grooves respectively, the mechanical connection between the outer ring structure 11 and the inner plate 12 is realized, which enhances the overall structural rigidity and deformation resistance of the safety net body 1. Furthermore, the layout of the connecting piece 2 is made more precise and controllable, improving the consistency and assembly accuracy of the product.

[0067] Specifically, the first groove is evenly spaced along the circumference of the ring 111, and the second groove is evenly spaced along the circumference of the inner disk 12. The first and second grooves that cooperate are located in the same radial plane of the ring 111, so that the extension lines of each connector 2 and each blocking member 112 can intersect at one point after installation, and the intersection point is located on the axis of the inner disk 12, making the layout of the opening 113 more uniform and regular.

[0068] like Figure 5 As shown, there are 6 connectors 2 arranged circumferentially along the inner disc 12, and 54 blocking members 112. Nine blocking members 112 are evenly distributed between the connecting segments 23 of every two connectors 2. These nine blocking members 112 and one connecting segment 23 form a group. The gap between adjacent blocking members 112 and between a blocking member 112 and an adjacent connecting segment 23 is no greater than 9.5 mm to prevent human hands from entering. The outer extension 21 is approximately 15 mm long and bends inward to form a mating hole 22.

[0069] A second aspect of this utility model provides a range hood, such as... Figure 8 As shown, the range hood provided in the second aspect of this utility model includes a housing assembly 5, a second oil cup 6, and the aforementioned lower panel assembly. The second oil cup 6 and the baffle 41 are both connected to the housing assembly 5, and an oil guiding path is formed between the baffle plate 4, the housing assembly 5, and the second oil cup 6.

[0070] When the range hood is in operation, the high-temperature oil fumes condense into oil droplets on the cold surface. The oil droplets flow along the inner surface of the baffle plate 4 to the outer shell assembly 5, and are guided by the outer shell assembly 5 to the second oil cup 6, thus realizing the automatic oil guiding function.

[0071] In the above embodiments, the baffle plate 4 also integrates an oil guiding function, which facilitates the transfer and discharge of the oil accumulated on it into the second oil cup 6, thereby improving the reliability of the product and the user experience.

[0072] In alternative implementations, such as Figure 6 and Figure 8 As shown, the retaining ring plate 4 is provided with an oil guiding structure 43, such as... Figure 4 As shown, the outer casing assembly 5 includes a base plate 51 located outside the baffle 41. The base plate 51 has an oil leakage hole that communicates with the oil guiding structure 43. The second oil cup 6 is connected to the side of the base plate 51 away from the baffle 41 and communicates with the oil leakage hole.

[0073] Through the above structural design, when the range hood is running, the centrifugal force generated by the impeller rotation causes oil droplets to be thrown out and intercepted by the baffle ring 42. The oil droplets flow along the surface of the baffle ring 42, enter the oil guiding structure 43, and then flow along its inner wall into the oil leakage channel 431 of the oil guiding structure 43 and drip onto the bottom plate 51. Subsequently, they fall into the second oil cup 6 through the oil leakage hole on the bottom plate 51, allowing the condensed oil to flow smoothly into the second oil cup 6 for centralized storage.

[0074] In alternative implementations, such as Figure 3 As shown, the range hood also includes a control panel 7 and a light 8. The control panel 7 is installed inside the housing assembly 5 on the front of the range hood, and the light 8 is installed on the lower side of the housing assembly 5, facing the cooktop.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
