Description
Technical Field
[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a dual-suction range hood. Background Technology
[0002] In the kitchen appliance sector, range hoods, as key devices for eliminating cooking fumes and improving kitchen air quality, are closely linked to market demand. With the improvement of consumers' living standards and their increasing requirements for the kitchen environment, the variety of range hoods on the market is becoming increasingly diverse to meet the varied preferences of different consumers in terms of function, appearance, and operating habits.
[0003] In recent years, top-and-side dual-suction range hoods have become increasingly popular with consumers due to their unique smoke extraction design. This type of range hood combines the advantages of top and side air intakes, intercepting and absorbing smoke at different stages of its rise, achieving a more efficient smoke extraction effect and providing consumers with a relatively clean kitchen environment.
[0004] However, existing conventional top-and-side dual-suction range hoods have a significant problem. Both the top and sides have air inlets directly mounted without any external obstruction. In actual use, especially during prolonged cooking, grease and grime from the cooking fumes adhere to the air inlets with the airflow. Over time, a large amount of grease accumulates at the air inlets, severely affecting the range hood's appearance and detracting from the overall look of the kitchen, while also placing a considerable cleaning burden on consumers.
[0005] Therefore, developing a range hood that can maintain good smoke extraction while effectively reducing the accumulation of oil stains at the air inlet, thus reducing the frequency and difficulty of cleaning, has become a pressing technical problem for the range hood industry. Utility Model Content
[0006] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, the purpose of this utility model is to provide a dual-suction range hood, which has two smoke collection chambers arranged close together at the top and bottom on the front side of the housing to enhance the smoke extraction effect, and a movable baffle is set outside the upper smoke collection chamber. When the range hood is not in use, the movable baffle can cover the main smoke collection chamber, making the overall appearance beautiful and eliminating the need for frequent cleaning.
[0007] This utility model provides a dual-suction range hood, including a box with a smoke guiding chamber, and the front side of the box includes a first smoke collection hood and a second smoke collection hood connected vertically in sequence. The first smoke collection hood and the second smoke collection hood are respectively provided with a first smoke gathering chamber and a second smoke gathering chamber that are concave and connected to the smoke guiding chamber. The second smoke gathering chamber is located close to the first smoke gathering chamber. The first smoke collection hood is provided with a movable baffle to open and close the first smoke gathering chamber.
[0008] In the above technical solution, by sequentially arranging a first smoke collection hood and a second smoke collection hood on the front side of the range hood, and correspondingly setting a first smoke gathering chamber and a second smoke gathering chamber with the second smoke gathering chamber close to the first smoke gathering chamber, this layout can more effectively cover the rising and diffusion path of cooking fumes, allowing more fumes to be drawn into the range hood, thereby enhancing the smoke extraction effect. Furthermore, a movable baffle is installed outside the upper first smoke collection hood, which can be covered after cooking, preventing the first smoke gathering chamber from being directly exposed. This makes the overall appearance of the range hood cleaner and more aesthetically pleasing, eliminating the need for frequent cleaning of the first smoke collection hood and improving the overall image of the kitchen.
[0009] In some embodiments, the first smoke collection chamber is provided with a first air inlet, and the second smoke collection chamber is provided with a second air inlet, and the planes where the first air inlet and the second air inlet are located form different angles with the horizontal plane.
[0010] In the above technical solution, by setting the first and second air inlets at different angles to the horizontal plane, the coverage area for fume extraction is increased, allowing more fumes to be drawn into the range hood. The different angles of the air inlets also facilitate the natural drainage of condensed oil along the direction of inclination.
[0011] In some embodiments, an oil drain groove is provided at the connection between the first smoke collection hood and the second smoke collection hood. The upper end of the oil drain groove is connected to the first smoke collection chamber, and the lower end of the oil drain groove is connected to the smoke guiding chamber and faces the second smoke collection hood.
[0012] In the above technical solution, by setting an oil drain groove at the connection between the first and second smoke collection hoods, with the upper end of the oil drain groove connected to the first smoke collection chamber and the lower end connected to the smoke guiding chamber and facing the second smoke collection hood, the problem of the flow direction of condensed oil at the first smoke collection hood is effectively solved. The condensed oil generated in the first smoke collection chamber can flow smoothly into the interior of the cabinet through the oil drain groove and flow away along the second smoke collection hood, avoiding the accumulation of condensed oil at the connection, reducing kitchen pollution caused by condensed oil dripping, and maintaining the cleanliness of the kitchen.
[0013] In some embodiments, the upper end of the second smoke hood abuts against the outer side wall of the lower end of the first smoke hood, and the oil drain groove is disposed vertically through the abutment of the first smoke hood and the second smoke hood.
[0014] In the above technical solution, by abutting the upper end of the second fume hood against the outer side of the lower end of the first fume hood, the oil drain groove is located on the inner side of the second fume hood. Under the influence of gravity, the condensed oil flows along the inner wall of the first fume hood to the abutment point and then directly into the oil drain groove located on the inner side of the second fume hood, thus preventing the condensed oil from flowing to the outside of the second fume hood. This not only keeps the exterior of the range hood clean and reduces kitchen pollution caused by oil droplets, but also prevents oil droplets from accumulating on the outside of the second fume hood and dripping onto the stove or other items, improving the safety and hygiene of kitchen use.
[0015] In some embodiments, the outer edge wall of the first smoke hood located below the first smoke collection chamber is provided with an inwardly recessed clearance portion, and the oil leakage groove is formed between the clearance portion and the inner edge wall of the second smoke hood located above the second smoke collection chamber. The lower end of the first smoke collection hood is spaced apart from the second smoke collection hood in the smoke guiding cavity, serving as the outlet of the oil leakage groove.
[0016] In the above technical solution, by providing an inwardly recessed clearance portion on the outer wall of the lower end of the first smoke hood, and allowing the inner wall of the upper end of the second smoke hood to abut against the outer wall of the lower end of the first smoke hood, on the one hand, this abutment method provides a stable connection between the first and second smoke hoods, ensuring the stability of the overall structure of the range hood and reducing the risk of noise and malfunctions caused by loose components. On the other hand, the clearance portion and the inner wall of the upper end of the second smoke hood naturally form an oil drain groove, allowing condensed oil to flow accurately into the oil drain groove along the inner wall of the first smoke hood, avoiding the random flow of condensed oil caused by the large area and complex structure of the first smoke hood. At the same time, this design is simple in structure, requiring no additional complex connecting parts or oil drain groove manufacturing processes, reducing production costs, and facilitating the cleaning and maintenance of the oil drain groove later, thus improving the user experience.
[0017] In some embodiments, the first smoke collection hood is inclined, the first smoke collection cavity is formed by recessing inward from the middle portion of the first smoke collection hood, and the second smoke collection hood includes an inclined second cover plate and a folding plate, and the second smoke collection cavity is formed by recessing inward from the middle portion of the second cover plate. The avoidance part is located at the edge of the first smoke collection hood below the first smoke collection chamber; the folding plate is folded upward from the upper edge of the second cover plate and abuts against the edge of the first smoke collection hood below the first smoke collection chamber.
[0018] In the above technical solution, a first smoke-collecting chamber is formed in the middle part of the first cover plate, and a second smoke-collecting chamber is formed in the middle part of the second cover plate. An upward-folding flap is provided at the upper end of the second cover plate, connecting with the lower edge of the first cover plate to form an oil-draining groove. This design does not occupy space in the smoke-collecting chamber, ensuring sufficient effective smoke collection area. Simultaneously, the upward-folding flap effectively prevents oil leakage caused by an excessively low outer wall of the oil-draining groove. Condensed oil can accurately flow into the oil-draining groove and drain smoothly, avoiding potential malfunctions and odors caused by oil dripping, thus improving the reliability and service life of the range hood. Furthermore, this structure is simple and reasonable, easy to operate during manufacturing and installation, and reduces production costs.
[0019] In some embodiments, the bottom end of the second smoke hood is provided with an oil leakage hole, and the side of the second smoke hood located inside the smoke guiding cavity has a guide channel located between the oil leakage groove and the oil leakage hole; The dual-suction range hood also includes an oil cup disposed below the second smoke collection hood, with the top opening of the oil cup located below the lower edge of the second smoke collection chamber and below the oil leakage hole.
[0020] In the above technical solution, by setting a guide channel between the oil draining groove and the oil draining hole at the bottom of the second smoke collection hood, the condensed oil flowing down from the oil draining groove can be accurately guided to the oil draining hole, and then smoothly enter the oil cup below through the oil draining hole. This avoids condensed oil remaining in the second smoke collection hood or flowing around, improves the efficiency of condensed oil discharge, ensures the cleanliness of the inside of the range hood, and reduces malfunctions that may be caused by oil accumulation. Furthermore, the opening of the oil cup is located below the lower edge of the second smoke collection chamber, allowing the condensed oil in the second smoke collection chamber to flow directly downwards into the oil cup, further ensuring comprehensive collection of condensed oil, preventing oil droplets from scattering, maintaining the cleanliness of the environment around the range hood, reducing odor generation, and improving the user experience.
[0021] In some embodiments, the middle portion of the second smoke hood protrudes from the outside to the inside, forming the second smoke collection chamber on the outside of the housing and forming a protruding portion inside the housing; The left and right ends of the second smoke hood are connected to the left and right side walls of the box body, and the flow channel is located between the protruding part and the left and right side walls of the box body.
[0022] In the above technical solution, by setting the middle part of the second smoke hood to protrude from the outside to the inside, a protruding part is formed inside the box, and a guide channel is naturally formed between the protruding part and the left and right side walls of the box. The guide channel is formed by the structure of the second smoke hood itself, without the need to set up additional complex guide components, simplifying the structure of the range hood, reducing production costs, and also facilitating manufacturing and installation.
[0023] In some embodiments, a decorative strip is also included, which is detachably attached to the outer wall of the upper edge of the second smoke hood.
[0024] In the above technical solution, a decorative strip is detachably attached to the outer wall (folding plate) of the upper edge of the second smoke hood, effectively solving the problems of unsightly appearance and condensate leakage caused by the connection hole connecting the first smoke hood to the folding plate. After the decorative strip covers the mounting hole, the range hood appears cleaner and more aesthetically pleasing. The decorative strip on the outer side of the folding plate conceals the connection hole, enhancing the range hood's appearance. Furthermore, the top of the decorative strip protrudes from the top of the folding plate and is higher than the lower edge of the opening of the first smoke collection chamber, further preventing condensate leakage.
[0025] In some embodiments, the decorative strip includes a strip-shaped body and a snap-fit edge folded down from the top of the strip-shaped body, wherein a snap-fit groove is formed between the snap-fit edge and the strip-shaped body, and the snap-fit groove snaps into the upper edge of the second smoke hood.
[0026] In the above technical solution, the joint edge folds inward and downward from the top of the strip-shaped body, and the two work together to form a snap-fit groove. The stable snap-fit structure formed by the folded plate and the snap-fit groove ensures the firmness and reliability of the decorative strip installation, and is convenient for installation and disassembly.

[0031] To better understand the above-mentioned objectives, features, and advantages of this utility model, the solution of this utility model will be further described below. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.
[0032] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.
[0033] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0034] like Figures 1 to 11 As shown, the embodiment of this utility model provides a dual-suction range hood that can draw air at different heights on the side of the range hood, and can intercept and absorb oil fumes at different stages of their rise, thus achieving a more efficient oil fume extraction effect.
[0035] The dual-suction range hood includes a housing 1, the interior of which has a smoke-guiding chamber. The housing 1 is located above the stovetop and is used to draw in cooking fumes.
[0036] The front side of the housing 1 includes a first smoke collection hood 11 and a second smoke collection hood 12 connected vertically, with the first smoke collection hood 11 positioned above the second smoke collection hood 12. The first smoke collection hood 11 has a recessed first smoke gathering chamber 1113, and the second smoke collection hood 12 has a recessed second smoke gathering chamber 1213. Both the first and second smoke gathering chambers 1113 are connected to the smoke guiding chamber. The first smoke collection hood 11 is the main smoke collection hood of the range hood, and the first smoke gathering chamber 1113 is the main smoke gathering chamber of the range hood, providing a larger smoke gathering area.
[0037] The second smoke collection chamber 1213 is located close to the first smoke collection chamber 1113, and the first smoke collection hood 11 is provided with a movable baffle 15 to open and close the first smoke collection chamber 1113.
[0038] In this embodiment, by sequentially arranging a first smoke collection hood 11 and a second smoke collection hood 12 on the front side of the housing 1, and correspondingly providing a concave first smoke gathering chamber 1113 and a second smoke gathering chamber 1213, with the second smoke gathering chamber 1213 close to the first smoke gathering chamber 1113, this layout can more effectively cover the rising and diffusion path of cooking fumes, allowing more fumes to be drawn into the range hood, thereby enhancing the smoke extraction effect. Furthermore, a movable baffle 15 is provided outside the upper first smoke collection hood 11, which can be covered after cooking, preventing the first smoke gathering chamber 1113 from being directly exposed. This makes the overall appearance of the range hood cleaner and more aesthetically pleasing, eliminating the need for frequent cleaning of the first smoke collection hood 11 and improving the overall image of the kitchen.
[0039] In the above embodiments, the materials of the first smoke hood 11 and the second smoke hood 12 can be selected from a variety of options. In addition to common metal materials (such as stainless steel), engineering plastics with certain strength and corrosion resistance can also be used.
[0040] The concave shapes of the first smoke-gathering chamber 1113 and the second smoke-gathering chamber 1213 are not limited to specific geometric shapes. In addition to arc-shaped concave shapes, they can also be square concave shapes, trapezoidal concave shapes, etc. Different concave shapes may have a certain impact on the gathering effect of oil fumes, but as long as the function of effectively gathering smoke is achieved, they are all within the acceptable range.
[0041] The movable baffle 15 is rotatable relative to the first smoke hood 11. The movable baffle 15 can be electrically driven, such as by a motor driving a gear and rack mechanism to open and close the movable baffle 15; or it can be manually driven, for example by setting a handle on the movable baffle 15 and opening and closing it by pushing and pulling manually.
[0042] like Figures 2 to 4 As shown, the first smoke collection hood 11 and the second smoke collection hood 12 form different angles with the horizontal plane. The first smoke collection chamber 1113 has a first air inlet 1114 at its concave bottom, and the second smoke collection chamber 1213 has a second air inlet 1214 at its concave bottom. The plane containing the first air inlet 1114 forms a first angle with the horizontal plane, and the plane containing the second air inlet 1214 forms a second angle with the horizontal plane. The second angle is smaller than the first angle, which is beneficial for drawing in oil fumes from different positions and discharging condensed oil.
[0043] Preferably, the first included angle and the second included angle are acute angles. For example, the first included angle is 40°-60° and the second included angle is 20°-35°.
[0044] In this embodiment, by setting the first air inlet 1114 and the second air inlet 1214 at different angles to the horizontal plane, the coverage area for fume extraction is increased, allowing more fume to be drawn into the range hood. The different angles of the air inlets also facilitate the natural drainage of condensed oil along the direction of inclination.
[0045] like Figures 4 to 10 As shown, an oil drain groove 13 is provided at the connection between the first smoke collection hood 11 and the second smoke collection hood 12. The oil drain groove 13 has a certain extension length and extends along the left and right direction of the range hood. The first smoke collection hood 11 and the second smoke collection hood 12 can be connected by means of screwing, riveting, snap-fitting, etc. The upper end of the oil drain groove 13 is connected to the first smoke gathering chamber 1113, and the lower end of the oil drain groove 13 is connected to the smoke guiding chamber and faces the second smoke collection hood 12.
[0046] When the range hood is running, cooking fumes enter the first smoke collection chamber 1113. During the contact between the fumes and the inner wall of the first smoke collection chamber 1113, some oil droplets condense inside. The condensed oil produced in the first smoke collection chamber 1113 flows down its inner wall to the upper end of the oil drain trough 13. The lower end of the oil drain trough 13 connects to the smoke guiding chamber, and its opening faces the second smoke collecting hood 12. In this way, the condensed oil enters the interior of the housing 1 and, under the influence of gravity, continues to flow downwards along the second smoke collecting hood 12 within the smoke guiding chamber, eventually being discharged from the range hood.
[0047] In this embodiment, by setting an oil drain groove 13 at the connection between the first smoke collection hood 11 and the second smoke collection hood 12, and by connecting the upper end of the oil drain groove 13 to the first smoke gathering chamber 1113 and the lower end to the smoke guiding chamber and facing the second smoke collection hood 12, the problem of the flow direction of condensed oil at the first smoke collection hood 11 is effectively solved. The condensed oil generated in the first smoke gathering chamber 1113 can flow smoothly into the interior of the cabinet 1 through the oil drain groove 13 and flow away along the second smoke collection hood 12, avoiding the accumulation of condensed oil at the connection, reducing kitchen pollution caused by condensed oil dripping, and maintaining the cleanliness of the kitchen.
[0048] In some embodiments, the upper end of the second smoke hood 12 abuts against the outer side of the lower end of the first smoke hood 11, and the oil drain groove 13 is disposed vertically through the abutment of the first smoke hood 11 and the second smoke hood 12.
[0049] The oil leakage groove 13 is located between the first smoke hood 11 and the second smoke hood 12.
[0050] The upper end of the second smoke hood 12 is higher than or flush with the lower edge of the opening of the first smoke chamber 1113.
[0051] In this embodiment, by abutting the upper end of the second fume hood 12 against the outer side of the lower end of the first fume hood 11, the oil drain groove 13 is located inside the second fume hood 12. Under the influence of gravity, the condensed oil flows along the inner wall of the first fume hood 11 to the abutment point and then directly into the oil drain groove 13 located inside the second fume hood 12, thus preventing the condensed oil from flowing to the outside of the second fume hood 12. This not only keeps the exterior of the range hood clean and reduces kitchen pollution caused by oil droplets, but also prevents oil droplets from accumulating on the outside of the second fume hood 12 and potentially dripping onto the stove or other items, improving the safety and hygiene of kitchen use.
[0052] In the above embodiments, an oil drain groove 13 can be provided between the abutment of the first smoke hood 11 and the second smoke hood 12, or multiple oil drain grooves 13 can be provided between the abutment of the first smoke hood 11 and the second smoke hood 12, with the multiple oil drain grooves 13 distributed at intervals. An oil drain outlet can be provided at the bottom of the oil drain groove 13, or the oil drain groove 13 can be a through groove with the entire bottom open.
[0053] The first smoke hood 11 extends downwards from the top of the housing 1 to near the bottom wall of the housing 1, meaning that the first smoke hood 11 occupies most of the front side of the housing 1, and the first smoke collection chamber 1113 is located at least in the upper middle part of the front side of the housing 1.
[0054] The outer side wall of the lower end of the first smoke hood 11 is provided with an inwardly recessed relief portion 1115, and an oil leakage groove 13 is formed between the relief portion 1115 and the inner side wall of the upper end of the second smoke hood 12. The lower end of the first smoke hood 11 and the second smoke hood 12 in the smoke guiding chamber are spaced apart to serve as the outlet of the oil leakage groove 13.
[0055] In this embodiment, by providing an inwardly recessed clearance portion 1115 on the outer side wall of the lower end of the first smoke hood 11, and allowing the inner side wall of the upper end of the second smoke hood 12 to abut against the outer side wall of the lower end of the first smoke hood 11, this abutment method provides a stable connection between the first smoke hood 11 and the second smoke hood 12, ensuring the stability of the overall structure of the range hood and reducing the risk of noise and malfunctions caused by loose components. On the other hand, the clearance portion 1115 and the inner side wall of the upper end of the second smoke hood 12 naturally form an oil drain groove 13, allowing condensed oil to flow accurately into the oil drain groove 13 along the inner wall of the first smoke hood 11, avoiding the random flow of condensed oil caused by the large area and complex structure of the first smoke hood 11. At the same time, this design is simple, requiring no additional complex connecting components or manufacturing processes for the oil drain groove 13, reducing production costs, and facilitating the cleaning and maintenance of the oil drain groove 13 later, thus improving the user experience.
[0056] The outer wall at the lower end of the first smoke collection hood 11 can be the cavity side wall of the first smoke collection chamber 1113, or it can be the outer wall of the edge of the first smoke collection hood 11 located below the first smoke collection chamber 1113. The outer wall at the upper end of the second smoke collection hood 12 can be the cavity side wall of the second smoke collection chamber 1213, or it can be the inner wall of the edge of the second smoke collection hood 12 located above the second smoke collection chamber 1213.
[0057] like Figures 6 to 10 As shown, in some embodiments, the first smoke collection hood 11 is inclined, and the first smoke gathering cavity 1113 is recessed inward from the middle portion of the first smoke collection hood 11. The second smoke collection hood 12 includes an inclined second cover plate 121 and a folding plate 122 that folds upward from the upper edge of the second cover plate 121. The second smoke gathering cavity 1213 is recessed inward from the middle portion of the second cover plate 121.
[0058] The clearance part 1115 is provided on the outer edge wall of the first smoke hood 11 located below the first smoke collection chamber 1113. Part of the folding plate 122 abuts against the outer edge wall of the lower end of the first smoke hood 11 and is connected by screws or rivets, while the other part cooperates with the clearance part 1115 to form an oil leakage groove 13.
[0059] In this embodiment, a first smoke-collecting chamber 1113 is formed in the middle portion of the first cover plate 111, and a second smoke-collecting chamber 1213 is formed in the middle portion of the second cover plate 121. An upwardly folding plate 122 is provided at the upper end of the second cover plate 121, connecting the folding plate 122 to the lower edge of the first cover plate 111 to form an oil-draining groove 13. This design does not occupy the space of the smoke-collecting chamber, ensuring that the smoke-collecting chamber has a sufficient effective smoke-collecting area. Simultaneously, the upward folding of the folding plate 122 effectively prevents oil leakage caused by an excessively low outer wall of the oil-draining groove 13. Condensed oil can accurately flow into the oil-draining groove 13 and be smoothly discharged, avoiding potential malfunctions and odors caused by oil dripping and improving the reliability and service life of the range hood. Furthermore, this structure is simple and reasonable, easy to operate during manufacturing and installation, and reduces production costs.
[0060] Preferably, the first smoke-collecting cavity 1113 is trapezoidally concave. The cavity sidewall below the concave bottom of the first smoke-collecting cavity 1113 is inclined downwards towards the front. The vertical length of the outer edge wall of the first smoke-collecting hood 11 located below the first smoke-collecting cavity 1113 is much smaller than the vertical length of the opening of the first smoke-collecting cavity 1113. The top of the inner edge wall of the second smoke-collecting hood 12 located above the second smoke-collecting cavity 1213 is higher than the lower edge of the opening of the first smoke-collecting cavity 1113. The folding plate 122 is a straight plate.
[0061] The first cover plate 111 includes a first smoke-gathering chamber plate 1112 and a first annular plate 1111. The outer periphery of the first smoke-gathering chamber plate 1112 is connected to the inner ring side of the first annular plate 1111. The first air inlet 1114 is disposed on the bottom wall of the first smoke-gathering chamber plate 1112, and the clearance portion 1115 is disposed on the first annular plate 1111.
[0062] The second cover plate 121 includes a second smoke-collecting chamber plate 1212 and a second annular plate 1211. The outer periphery of the second smoke-collecting chamber plate 1212 is connected to the inner ring side of the second annular plate 1211. The second air inlet 1214 is disposed on the bottom wall of the second smoke-collecting chamber plate 1212, and the folding plate 122 is connected to the upper edge of the second annular plate 1211.
[0063] The lower end of the first annular plate 1111 and the upper end of the second annular plate 1211 are spaced apart on one side wall of the smoke guiding chamber to form the outlet of the oil leakage groove 13.
[0064] The second smoke hood 12 has an oil drain hole 1232 at its bottom end. Preferably, the second smoke hood 12 also includes a base plate 123, which is connected to the bottom edge of the second cover plate 121. The inner wall of the base plate 123 has a recessed oil collection groove 1231, and the oil drain hole 1232 is located in the oil collection groove 1231.
[0065] like Figures 9 to 10As shown, the second smoke hood 12 has a guide channel on one side of the smoke guiding chamber, which is located between the oil leakage groove 13 and the oil leakage hole 1232. Its function is to guide the condensed oil flowing down from the oil leakage groove 13 to the oil leakage hole 1232, so as to ensure that the condensed oil can be smoothly discharged from the second smoke hood 12.
[0066] The dual-suction range hood also includes an oil cup 2 located below the second smoke collection hood 12. The top opening of the oil cup 2 is located below the lower edge of the second smoke collection chamber 1213 and below the oil drain hole 1232.
[0067] In this embodiment, by setting a guide channel between the oil drain trough 13 and the oil drain hole 1232 at the bottom of the second smoke collection hood 12, the condensed oil flowing down from the oil drain trough 13 can be accurately guided to the oil drain hole 1232, and then smoothly enter the oil cup 2 below through the oil drain hole 1232. This avoids the condensed oil remaining in the second smoke collection hood 12 or flowing around, improves the discharge efficiency of the condensed oil, ensures the cleanliness of the inside of the range hood, and reduces malfunctions that may be caused by the accumulation of oil. Furthermore, the opening of the oil cup 2 is located below the lower edge of the second smoke collection chamber 1213, allowing the condensed oil in the second smoke collection chamber 1213 to flow directly downwards into the oil cup 2, further ensuring the comprehensiveness of condensed oil collection, preventing oil droplets from scattering, maintaining the cleanliness of the environment around the range hood, reducing odor generation, and improving the user experience.
[0068] The middle part of the second smoke hood 12 protrudes from the outside to the inside, forming a second smoke collection chamber 1213 on the outside of the box body 1 and a protruding part, namely the second smoke collection chamber plate 1212, on the inside of the box body 1.
[0069] The left and right ends of the second smoke hood 12 are connected to the left and right side walls of the housing 1. The flow channel is located between the protruding part and the left and right side walls of the housing 1.
[0070] In this embodiment, by protruding the middle part of the second smoke hood 12 from the outside to the inside, a protruding part is formed inside the box 1, and a guide channel is naturally formed between the protruding part and the left and right side walls of the box 1. The guide channel is formed by utilizing the structure of the second smoke hood 12 itself, without the need to set up additional complex guide components, which simplifies the structure of the range hood, reduces production costs, and facilitates manufacturing and installation.
[0071] Specifically, the left side plate of the adjacent second smoke collection chamber plate 1212, the left side wall of the box body 1, and the second annular plate 1211 connecting the two cooperate to form a flow guide channel, and the right side plate of the adjacent second smoke collection chamber plate 1212, the right side wall of the box body 1, and the second annular plate 1211 connecting the two cooperate to form another flow guide channel.
[0072] The first smoke hood 11 has two first air inlets 1114 on the left and right sides, which are located on the left and right ends of the bottom of the first smoke collection chamber 1113. The second smoke hood 12 has two second air inlets 1214 on the left and right sides, which are located on the left and right ends of the bottom of the second smoke collection chamber 1213.
[0073] An oil mesh 3 is provided at the first air inlet 1114, and the oil mesh 3 has multiple first oil holes. Multiple second oil holes 4 are provided at the second air inlet 1214.
[0074] like Figure 4 , Figure 7 as well as Figures 10 to 11 As shown, the range hood also includes a decorative strip 14. The decorative strip 14 is detachably attached to the outer wall of the upper edge of the second smoke collection hood 12, such as by magnetic attraction or snap-fit. That is, the decorative strip 14 is detachably attached to the folding plate 122 of the second smoke collection hood 12.
[0075] The folding plate 122 has multiple connection holes for connecting the first smoke collection hood 11. These connection holes disrupt the flatness of the surface of the folding plate 122, affecting the overall aesthetics of the range hood, and may also cause condensed oil to leak out at the connection holes.
[0076] In this embodiment, a decorative strip 14 is detachably attached to the outer wall (folding plate 122) of the upper edge of the second smoke hood 12, effectively solving the problems of unsightly appearance and condensate leakage caused by the connection hole connecting the first smoke hood 11 to the folding plate 122. After the decorative strip 14 covers the mounting hole, the range hood looks cleaner and more aesthetically pleasing. The decorative strip 14 on the outer side of the folding plate 122 can cover the connection hole, making the range hood look more attractive. Secondly, the top of the decorative strip 14 protrudes from the top of the folding plate 122 and is higher than the lower edge of the opening of the first smoke collection chamber 1113, which can also prevent condensate leakage.
[0077] Preferably, the decorative strip 14 is snapped onto the folding plate 122. The decorative strip 14 can be made of various materials, such as plastic or silicone, and can be selected according to design requirements and cost considerations.
[0078] In some embodiments, the decorative strip 14 includes a strip-shaped body 141 and a snap-fit edge 142 that folds downward from the top of the strip-shaped body 141. A snap-fit groove 143 is formed between the snap-fit edge 142 and the strip-shaped body 141, and the snap-fit groove 143 snaps into the upper edge of the second smoke hood 12.
[0079] In this embodiment, the snap-fit edge 142 folds inward and downward from the top of the strip-shaped body 141, and the two cooperate to form a snap-fit groove 143. The stable snap-fit structure formed by the folded plate 122 and the snap-fit groove 143 ensures the firmness and reliability of the decorative strip 14 installation, and is convenient for installation and disassembly.
[0080] The folding plate 122 extends downward from its top to form a snap-fit interface 1221. The lower end of the snap-fit edge 142 has a protruding edge, which snaps into the snap-fit interface 1221 of the folding plate 122. Connecting holes are spaced apart on the folding plate 122, and snap-fit edges 142 are spaced apart on the inner sidewall of the strip-shaped body 141, and are staggered with the connecting holes.
[0081] The strip-shaped body 141 is elongated. The length of the strip-shaped body 141 is the same as the left and right extension length of the box body 1.
