Description

Technical Field

[0001] This utility model relates to the field of kitchenware technology, and in particular to a folding smoke collection device and a range hood. Background Technology

[0002] In existing range hood technology, to achieve effective smoke adsorption, some solutions incorporate an opening and closing panel structure at the smoke inlet, utilizing the power control panel's on / off state. When the panel is open, the smoke extraction efficiency of the inlet adjusts with the opening angle, and the range of the smoke collection area changes accordingly. To further enhance the smoke collection effect, some designs add movable smoke-collecting plates on both sides of the opening and closing panel. These plates are linked to the panel, unfolding synchronously when the panel is opened to expand the smoke collection area, and retracting into the side of the range hood when it is closed.

[0003] However, the above-mentioned technical solutions have significant drawbacks in practical applications. First, the design of storing the smoke-gathering plate on the side of the range hood requires occupies lateral space, preventing further reduction in the thickness of the range hood's side walls. For range hoods aiming for a slimmer profile (such as L-shaped or wall-mounted range hoods), the side space is extremely limited, making it difficult to accommodate the smoke-gathering plate's storage structure. This problem directly restricts the flexibility of range hood design and hinders the technological iteration of ultra-thin range hoods. Utility Model Content

[0010] A further technical solution is that the smoke gathering assembly further includes a first rotating shaft, the smoke gathering plate base includes a first bushing, and a second bushing and a third bushing are respectively provided on both sides of the first folding plate; the first rotating shaft passes through the first bushing and the second bushing.

Detailed Implementation

[0034] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Similar component reference numerals in the drawings represent similar components. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0035] It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or collections thereof.

[0036] It should also be understood that the terminology used in this specification of embodiments of the present invention is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of the present invention. As used in this specification of embodiments of the present invention and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0037] See Figures 1-10 This utility model embodiment proposes a folding smoke-gathering device. This folding smoke-gathering plate 22 does not occupy space on the side of the range hood, thus meeting the requirements of a slim and lightweight range hood design. To achieve the above technical objectives, the folding smoke-gathering device includes a housing 10, a driving device 30, and a smoke-gathering assembly 20, the specific structure of which is described below:

[0038] The housing 10 is provided with a smoke inlet 11. Specifically, the housing 10 is the outer shell of the range hood, and the smoke inlet 11 is the entrance for cooking fumes.

[0039] The smoke collection assembly 20 includes an opening and closing panel 21 and a folding smoke collection plate 22 connected to one side of the opening and closing panel 21. There may be two folding smoke collection plates 22, located on opposite sides of the opening and closing panel 21. The driving device 30 is mounted on the housing 10 and is connected to the smoke collection assembly 20.

[0040] In this invention, the driving device 30 can drive the opening and closing panel 21 to open the smoke inlet 11, and cause the folding smoke-gathering plate 22 to unfold and be disposed on one side of the opening and closing panel 21, thereby effectively gathering the oil fumes and preventing them from escaping. Furthermore, the driving device 30 can drive the opening and closing panel 21 to close the smoke inlet 11, and cause the folding smoke-gathering plate 22 to fold and be stored inside the smoke inlet 11. The folding smoke-gathering plate 22 folding and being stored inside the smoke inlet 11 avoids occupying the side space of the range hood.

[0041] In specific implementation, see Figures 1-2The range hood features a front-mounted opening panel 21. When the range hood is closed, the opening panel 21 closes the smoke inlet 11, resulting in a flat, simple design that facilitates cleaning. Simultaneously, the opening panel 21 opens the smoke inlet 11, and the folding smoke-gathering plates 22 on both sides of the panel open, forming a three-sided smoke-gathering area in front of the smoke inlet 11. The length of the smoke-gathering plates exceeds three-quarters of the width of the opening panel 21, meaning the side folding smoke-gathering plates 22 have a large area, preventing fumes from escaping from the sides of the range hood and improving smoke extraction efficiency. When open, the smoke inlet 11, opening panel 21, and folding smoke-gathering plates 22 together form a trumpet shape, radiating the negative pressure zone outwards and further enhancing smoke extraction. Furthermore, in this design, the opening panel 21 and the smoke-gathering plates are directly connected and linked, reducing the connection structure between the two components. The negative pressure zone of the smoke inlet 11 has a regular shape with no other protruding parts. When the range hood is turned off, the opening and closing panel 21 drives the folding smoke-gathering plate 22 to fold inward and be completely stored inside the range hood without affecting its appearance.

[0042] In this embodiment of the utility model, the folding smoke-gathering plate 22 is completely stored inside the smoke inlet 11 when the range hood is closed, avoiding the occupation of the side space of the range hood by traditional side-mounted storage, and is especially suitable for the compact design requirements of ultra-thin range hoods (such as 7-shaped or wall-mounted range hoods).

[0043] Furthermore, the opening and closing panel 21 and the smoke gathering plate share the same drive device 30, reducing independent transmission structures, which not only reduces mechanical complexity, but also ensures that the opening angle of the smoke gathering plate is precisely matched with the opening and closing state of the smoke inlet 11 through synchronous action, thereby enhancing the effectiveness of the smoke gathering range.

[0044] Furthermore, the drive unit 30 is directly integrated into the housing 10 to avoid external mechanical interference. At the same time, when stored, the smoke collection plate is hidden inside the smoke machine, reducing the risk of component damage caused by external pollution or collisions.

[0045] This utility model provides a folding smoke collection device, including a housing 10, a driving device 30, and a smoke collection assembly 20. The housing 10 has a smoke inlet 11, and the smoke collection assembly 20 includes an opening and closing panel 21 and a folding smoke collection plate 22 connected to one side of the opening and closing panel 21. The driving device 30 is mounted on the housing 10 and connected to the smoke collection assembly 20. The driving device 30 can drive the opening and closing panel 21 to open the smoke inlet 11 and drive the folding smoke collection plate 22 to unfold and be disposed on one side of the opening and closing panel 21. The driving device 30 can also drive the opening and closing panel 21 to close the smoke inlet 11 and drive the folding smoke collection plate 22 to fold and be stored inside the smoke inlet 11. In this utility model, the folding smoke collection plate 22 is completely stored inside the smoke inlet 11 when the range hood is closed, avoiding the occupation of the side space of the range hood by traditional side-mounted storage, and is especially suitable for the compact design requirements of ultra-thin range hoods (such as L-shaped or wall-mounted range hoods).

[0046] In some preferred embodiments, the driving device 30 includes a motor bracket 31, a motor 32, and a drive rod 33. The motor 32 is connected to the drive rod 33, and the drive rod 33 is connected to the smoke collection assembly 20. The motor 32 is fixed to the housing 10 through the motor bracket 31.

[0047] Specifically, the motor 32 is fixed to the motor bracket 31 by fasteners and / or snap-fit ​​structures, and the motor bracket 31 is fixed to the housing 10 by fasteners and / or snap-fit ​​structures. The rotating shaft of the motor 32 is connected to the drive rod 33. The motor 32 is fixed to the housing 10 by the bracket, ensuring a rigid connection between the drive device 30 and the main body of the smoke hood, preventing transmission deviation caused by vibration or displacement of the motor 32, and ensuring the synchronicity of the opening and closing panel 21 and the smoke gathering plate. The drive rod 33 directly connects the motor 32 and the smoke gathering assembly 20, simplifying the power transmission chain, reducing intermediate transmission components (such as gears, belts, etc.), and reducing space occupation and assembly complexity.

[0048] In some preferred embodiments, the smoke gathering assembly 20 further includes a smoke gathering plate base 23, a panel base 24, a driven rod 25, and a conversion head 26; the smoke gathering plate base 23 is fixedly disposed on the housing 10, and the panel base 24 is fixedly disposed on the panel; the driven rod 25 is rotatably connected to the drive rod 33 (e.g., through a rotating shaft), and the conversion head 26 is rotatably connected to the driven rod 25 and the panel base 24 respectively; the folding smoke gathering plate 22 includes a first folding plate 221 and a second folding plate 222, the two sides of the first folding plate 221 are rotatably connected to the panel base 24 and the second folding plate 222 respectively, and the two sides of the second folding plate 222 are rotatably connected to the first folding plate 221 and the panel base 24 respectively.

[0049] Specifically, the smoke-gathering plate base 23 is fixed to the housing 10 by fasteners and / or snap-fit ​​structures, and the panel base 24 is fixed to the panel by fasteners and / or snap-fit ​​structures. The conversion head 26 forms a multi-stage rotational connection with the driven rod 25 and the panel base 24, so that the unfolding / folding action of the folding smoke-gathering plate 22 is strictly synchronized with the displacement of the opening and closing panel 21, avoiding deviations in the smoke-gathering area due to mechanical delays. The first folding plate 221 and the second folding plate 222 are connected in series through the panel base 24 to form a chain folding structure, ensuring that the two plates are in place sequentially when unfolded to form a continuous smoke-gathering surface; when folded, the two plates are stacked and stored to avoid mutual interference.

[0050] See Figures 3-5In this embodiment of the invention, when the range hood is closed, the folding smoke-gathering plate 22 is fully folded and fixed between the opening / closing panel 21 and the smoke inlet 11. During the opening / closing process of the range hood opening / closing panel 21, the folding smoke-gathering plate 22 opens in conjunction with the opening / closing panel 21. After the opening / closing panel 21 is fully opened, the folding smoke-gathering plate 22 is fully opened on both sides of the opening / closing panel 21 at the smoke inlet 11, forming a three-sided smoke-gathering shape with the opening / closing panel 21. To prevent the opening / closing panel 21 from swaying left and right during its operation, in this solution, when the opening / closing panel 21 is fully open, the smoke-gathering plate is not perpendicular to the opening / closing panel 21. Since the smoke-gathering plates on both sides are symmetrical, the plane of the smoke-gathering plate, the opening / closing panel 21, and the smoke inlet 11 forms a stable isosceles trapezoid. The left and right directions of the opening and closing panel 21 are restricted by the inclined folding smoke-gathering plates 22 on both sides to prevent the opening and closing panel 21 from moving left and right. At the same time, since there is a dead point in the mechanism when the folding smoke-gathering plates 22 are stretched horizontally, the present invention designs inclined smoke-gathering plates, which can avoid the dead point in the mechanism during the folding process and ensure the reliability of operation.

[0051] In some preferred embodiments, the conversion head 26 includes a main body 261, a shaft 262 protruding from the lower side of the main body 261, and a shaft hole 263 formed on the side of the main body 261; the conversion head 26 is rotatably connected to the panel base 24 through the shaft 262, and the conversion head 26 is rotatably connected to the driven rod 25 through the shaft hole 263.

[0052] Specifically, the panel base 24 is provided with a shaft hole 263, and the shaft 262 is rotatably connected to the corresponding shaft hole 263 on the panel base 24. One end of the driven rod 25 is provided with a circular hole corresponding to the shaft hole 263, and a rotating shaft passes through the shaft hole 263 and the shaft hole 263 on the driven rod 25 to achieve a rotatable connection.

[0053] The shaft 262 and shaft hole 263 are respectively connected to the panel base 24 and the driven rod 25, forming a two-degree-of-freedom rotation structure, so that the conversion head 26 can adaptively adjust the angle during the driving process. The conversion head 26 always keeps the thrust direction facing the front of the opening and closing panel 21, ensuring that the thrust direction is always consistent with the unfolding trajectory of the smoke gathering plate.

[0054] The shaft body 262 and shaft hole 263 are integrated into the main body of the adapter head 26, reducing additional connecting parts (such as bearings and clips) and reducing the number of parts and assembly complexity.

[0055] In some preferred embodiments, the smoke gathering assembly 20 further includes a first rotating shaft 27, the smoke gathering plate base 23 includes a first bushing 231, and the two sides of the first folding plate 221 are respectively provided with a second bushing 2211 and a third bushing 2212; the first rotating shaft 27 passes through the first bushing 231 and the second bushing 2211.

[0056] Furthermore, the smoke collection assembly 20 also includes a second rotating shaft 28, and a fourth bushing 2221 and a fifth bushing 2222 are respectively provided on both sides of the second folding plate 222; the second rotating shaft 28 passes through the third bushing 2212 and the fourth bushing 2221.

[0057] Furthermore, the smoke collection assembly 20 also includes a third rotating shaft 29, and the panel base 24 includes a sixth bushing 241, with the third rotating shaft 29 passing through the fifth bushing 2222 and the sixth bushing 241.

[0058] In this invention, the first rotating shaft 27, the second rotating shaft 28, and the third rotating shaft 29 pass through each bushing, forming a multi-level rotation fulcrum. This ensures that the unfolding / folding movements of the first folding plate 221 and the second folding plate 222 are performed along a fixed axis, avoiding mechanical jamming or frictional wear. The nested design of the rotating shafts and bushings enhances the rigidity of the connection nodes, preventing deformation of the folding plates due to negative pressure or external forces during unfolding.

[0059] Specifically, the second bushing 2211 has a first notch 2213 in the middle, the third bushing 2212 has a second notch 2214 in the middle, and the sixth bushing 241 has a third notch 242 in the middle; the first bushing 231 is embedded in the first notch 2213, the fourth bushing 2221 is embedded in the second notch 2214, and the fifth bushing 2222 is embedded in the third notch 242; plugs 210 are provided on both sides of the second bushing 2211, the third bushing 2212, and the sixth bushing 241.

[0060] In this invention, the notch design ensures the bushing is precisely inserted into the corresponding position, preventing misalignment that could lead to shaft displacement or friction. The plug 210 restricts axial displacement of the shaft, preventing it from slipping out of the bushing during long-term use and ensuring structural stability. The notch and plug 210 form a detachable connection structure, facilitating partial replacement of the shaft and bushing and reducing overall maintenance costs.

[0061] Furthermore, a torsion spring is fitted on the second rotating shaft 28, the torsion spring being configured to fold the folding smoke-gathering plate 22 toward the inside of the smoke inlet 11.

[0062] In this invention, the torsion spring forces the second rotating shaft 28 to rotate inward through preload, ensuring that the smoke-collecting plate folds strictly along a preset trajectory when closed, avoiding deviations in movement caused by gravity or inertia. The torsion spring constraint prevents the folding plate from accidentally unfolding or loosening, reducing the risk of mechanical failure during use.

[0063] The folding smoke collection device proposed in this utility model achieves significant technological breakthroughs in structural optimization and functional synergy through integrated design and linkage drive mechanism. Its technical effects can be systematically derived as follows:

[0064] 1. Improved space utilization

[0065] Traditional range hoods typically use a side-mounted smoke collection panel, which occupies space on the side of the hood, making it difficult to reduce the thickness of the side walls. This is especially problematic for ultra-thin range hoods (such as L-shaped or wall-mounted models), where this design severely restricts their compact design. This invention completely eliminates lateral space occupation by housing the folding smoke collection panel 22 inside the smoke inlet 11. Specifically, when the range hood is turned off, the drive device 30 simultaneously folds the folding smoke collection panel 22 inward and completely hides it within the smoke inlet 11, eliminating the need for pre-reserved mechanical storage space on the side walls of the range hood. This design not only meets the form requirements of ultra-thin range hoods but also provides greater flexibility in duct layout, avoiding uneven negative pressure zone distribution caused by a bulky structure.

[0066] 2. Reduced mechanical complexity and enhanced reliability

[0067] In existing technologies, the opening and closing panel 21 and the smoke collection plate often employ independent drive mechanisms, resulting in lengthy transmission chains, dispersed components, and a tendency for asynchronous actions or component wear due to mechanical delays. This invention integrates the opening and closing action of the opening and closing panel 21 and the unfolding / folding action of the folding smoke collection plate 22 into a single power system by using a shared drive device 30. The drive device 30 directly drives the smoke collection assembly 20 via a rigid connecting rod, reducing intermediate transmission components such as gears and belts, significantly lowering mechanical complexity. Simultaneously, the linkage design ensures a strict match between the displacement of the opening and closing panel 21 and the unfolding angle of the folding smoke collection plate 22, avoiding action deviations caused by independent control, thereby improving the reliability and lifespan of the entire machine.

[0068] 3. Improved smoke collection effect

[0069] In traditional solutions, insufficient coordination between the unfolding angle of the smoke-collecting plate and the opening / closing state of the smoke inlet 11 can easily cause oil fumes to escape from the sides. This invention utilizes a synchronous driving mechanism to cause the folding smoke-collecting plate 22 to unfold to a preset angle when the opening / closing panel 21 is opened, forming a three-sided smoke-collecting area. The unfolded smoke-collecting plate forms a continuous barrier with the edge of the smoke inlet 11, expanding the effective negative pressure zone coverage and significantly reducing the path of oil fume diffusion. Furthermore, the folding smoke-collecting plate 22, in its unfolded state, forms a stable geometric structure (such as an isosceles trapezoid) with the opening / closing panel 21, further restricting lateral airflow escape and enhancing oil fume adsorption efficiency.

[0070] 4. Ease of maintenance and adaptability for expansion

[0071] Modular design is an extended advantage of this solution. The drive unit 30 is independently installed in the housing 10, without interfering with the duct structure, facilitating disassembly, maintenance, or component replacement. Meanwhile, the swivel connection structure of the folding smoke-collecting plate 22 and its base fixing method support adaptation to different range hood shapes (such as European style and side-suction style). Cross-platform application can be achieved simply by adjusting the base installation position, significantly improving the versatility and market adaptability of the technical solution.

[0072] This utility model, through its core design of "built-in storage + linkage drive", systematically solves the problems of large lateral space occupation, high mechanical redundancy and insufficient smoke collection efficiency of traditional range hoods, and provides an innovative technical path for improving the thinness, efficiency and reliability of range hoods.
