Technical Field
[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a range hood. Background Technology
[0002] With current technology, range hoods have entered the kitchens of thousands of households. Range hoods can remove the oil fumes produced in the kitchen during the cooking process, reduce the coughing problem caused by oil fumes when people are cooking, and keep the kitchen clean and hygienic.
[0003] In related technologies, some range hoods use a smoke collection chamber that can move relative to the casing. When opened, the smoke collection chamber moves out of the casing to draw smoke. Therefore, the smoke collection chamber is an exposed part. However, there is oil accumulation on the main box and the fan volute inside the main box. After the oil flows down, it drips onto the top of the smoke collection chamber, making the smoke collection chamber difficult to clean and affecting its appearance.
[0004] Therefore, there is an urgent need to provide a range hood that can solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a range hood that can solve the problems of oil dripping onto the top of the smoke collection cavity, making it difficult to clean and aesthetically unappealing in the prior art.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] A range hood includes a housing, within which a smoke collection chamber is housed. The smoke collection chamber is movably connected to the housing and can be opened or closed relative to the housing. When opened, the smoke collection chamber is moved out of the housing.
[0008] An oil cup is provided at the bottom of the housing, and an adapter is connected to the upper side of the housing. A main box is connected to the upper side of the adapter. An oil receiving plate is located at the front bottom of the adapter, and an opening is opened at the rear bottom of the adapter. The housing communicates with the main box through the opening. An oil guide groove is also provided inside the adapter. The oil guide groove surrounds the front and left and right sides of the opening. The oil guide grooves located on the left and right sides are used to guide oil to the rear plate of the housing or the oil cup.
[0009] As an optional solution, the height of the oil receiving plate is higher than the height of the oil guiding groove.
[0010] As an alternative, the height of the oil receiving plate gradually increases from back to front.
[0011] As an optional solution, the inner wall of the oil receiving plate is provided with oil-blocking protrusions.
[0012] As an optional solution, the adapter includes an oil guide and a surrounding plate. The oil guide includes an oil receiving plate, an opening, and an oil guiding groove. The surrounding plate is disposed around the periphery of the oil guide. The left and right sides of the oil guide are bent and wrap around the surrounding plate from the outside, and are fixed by welding or riveting.
[0013] As an optional solution, a decorative cover is also included, which is disposed over the main housing and the adapter.
[0014] As an alternative, the decorative cover includes a cover body and a bottom decorative panel. The cover body surrounds the periphery of the main box and the adapter, and the bottom decorative panel surrounds the bottom of the adapter and is fastened to the bottom of the cover body.
[0015] As an optional solution, two mounting brackets are fixedly connected to the upper side of the housing. The two mounting brackets are located on the left and right sides of the adapter, respectively. The left and right sides of the cover are respectively provided with mounting protrusions arranged horizontally in the front-back direction. The mounting protrusions are fixedly connected to the mounting brackets by fasteners.
[0016] As an optional solution, the bottom edge of the smoke collection cavity and the orthographic projection of the rear plate in the vertical direction are both located within the range of the oil cup.
[0017] As an optional solution, a flap is also included, the top of which is rotatably connected to the top of the smoke collection chamber and can be flipped relative to the smoke collection chamber.
[0018] The beneficial effects of this utility model are:
[0019] This utility model provides a range hood where, in operation, the smoke collection chamber is open relative to the housing, allowing it to move outside the housing for smoke extraction; in non-operational mode, the smoke collection chamber is closed relative to the housing, concealing itself within the housing. This makes the range hood more compact and space-saving when not in use. When oil accumulates on the main housing and the fan casing inside, it is completely caught by the oil receiving plate of the adapter and flows backward along the plate, then into the oil guide groove. From there, it flows backward along the oil guide grooves on both sides to the rear plate, and finally into the oil cup at the bottom, or it flows backward along the oil guide grooves on both sides and falls directly into the oil cup. This prevents oil from dripping onto the top of the smoke collection chamber, which would otherwise be difficult to clean and aesthetically unappealing. Attached Figure Description

[0041] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0042] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

[0043] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0044] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0045] like Figure 1 and Figure 2 As shown, this embodiment provides a range hood, including a housing 1, with a smoke collection chamber 2 inside the housing 1. The smoke collection chamber 2 is movably connected to the housing 1 and can be opened or closed relative to the housing 1. When opened, the smoke collection chamber 2 moves out of the housing 1. An oil cup 4 is provided at the bottom of the housing 1. An adapter 5 is connected to the upper side of the housing 1. A main box 8 is connected to the upper side of the adapter 5. A fan mechanism is provided inside the main box 8. An oil receiving plate 511 is located at the bottom front side of the adapter 5. An opening 512 is opened at the bottom rear side of the adapter 5. The housing 1 is connected to the fan mechanism inside the main box 8 through the opening 512. An oil guiding groove 513 is also provided inside the adapter 5. The oil guiding groove 513 surrounds the front side and the left and right sides of the opening 512. The oil guiding grooves 513 located on the left and right sides are used to guide oil to the rear plate 17 of the housing 1 or the oil cup 4.
[0046] In the working state, the smoke collection chamber 2 is open relative to the housing 1, and the smoke collection chamber 2 moves outside the housing 1. The fan mechanism starts to generate negative pressure, and the smoke is drawn in through the smoke collection chamber 2. After the smoke enters the smoke collection chamber 2, it is discharged to the public flue or outdoors through the opening 512 and the main box 8, preventing the smoke from escaping. In the non-working state, the smoke collection chamber 2 is closed relative to the housing 1, so that the smoke collection chamber 2 is hidden inside the housing 1, making the range hood more compact and smaller when not in use, reducing the space occupied. The fan mechanism is close to the front and located above the oil receiving plate 511, such as... Figure 3The arrows indicate the direction of oil flow. When the oil on the side wall of the main box 8 and the fan casing inside the main box 8 flows downward, it will be caught by the oil receiving plate 511 of the adapter 5 and flow backward along the oil receiving plate 511. Then it will flow into the oil guide groove 513, and then flow backward along the oil guide grooves 513 on both sides to the rear plate 17. Finally, it will flow along the rear plate 17 to the oil cup 4 at the bottom, or flow backward along the oil guide grooves 513 on both sides and then fall directly into the oil cup 4. This can prevent the oil from dripping onto the top of the smoke collection chamber 2, which would make it difficult to clean and result in poor aesthetics.
[0047] like Figure 9 As shown, in this embodiment, the housing 1 also includes a bottom plate 14 located on the lower side. The oil cup 4 is detachably connected to the bottom of the bottom plate 14. The bottom plate 14 has multiple oil leakage holes. The oil guide groove 513 guides the accumulated oil to the rear plate 17, flows down along the rear plate 17 to the bottom plate 14, and flows into the oil cup 4 from the oil leakage holes. Alternatively, the accumulated oil flows backward along the guide groove 513, flows directly down to the bottom plate 14, and then flows into the oil cup 4 from the oil leakage holes.
[0048] Furthermore, the oil cup 4 is installed at the bottom of the housing 1 by pulling it out from the front and back. This allows the oil cup 4 to be easily disassembled for cleaning.
[0049] Optionally, such as Figure 2 and Figure 3 As shown, the adapter 5 includes an oil guide 51 and a surrounding plate 52. The oil guide 51 includes the aforementioned oil receiving plate 511, an opening 512, and an oil guiding groove 513. The surrounding plate 52 is disposed around the periphery of the oil guide 51. The left and right sides of the oil guide 51 are bent and wrap around the surrounding plate 52 from the outside, and are fixed by welding, resulting in a stable connection and preventing oil leakage caused by rivet or screw connections. In other optional embodiments, the left and right sides of the oil guide 51 can also be fixed to the surrounding plate 52 by riveting.
[0050] like Figure 3 As shown, the height of the oil receiving plate 511 is higher than the height of the oil guiding groove 513. This height difference is formed by bending the plate. The oil on the oil receiving plate 511 can flow backward along the surface, and then first flow into the oil guiding groove 513 extending in the horizontal direction. Then, it flows into the oil guiding grooves 513 on the left and right sides of the oil guiding groove 513, and flows backward along the oil guiding groove 513 to the rear plate 17. Finally, it flows through the rear plate 17 to the oil cup 4 at the bottom, or it flows backward along the oil guiding groove 513 and then falls directly into the oil cup 4, thus realizing the arrangement of the oil passage.
[0051] Optionally, the height of the oil receiving plate 511 gradually increases from back to front. That is, the oil receiving plate 511 is inclined so that the oil on the oil receiving plate 511 can flow smoothly to the rear side along the surface, avoiding oil accumulation on the oil receiving plate 511.
[0052] like Figure 3 As shown, the inner wall of the oil receiving plate 511 is provided with multiple oil-blocking protrusions 514. The oil-blocking protrusions 514 can prevent the oil on the oil receiving plate 511 from flowing backward, which can prevent the oil guide groove 513 from overflowing due to the excessive backward flow speed when a large amount of oil flows onto the oil receiving plate 511.
[0053] like Figure 4 As shown, the range hood also includes a decorative cover 9, which covers the main housing 8 and the adapter 5. The decorative cover 9 can prevent the connecting parts such as the adapter 5 from being exposed, ensuring that the overall appearance is free of screws, welding and other features, making it more aesthetically pleasing, and can also add a layer of oil circuit protection to the adapter 5.
[0054] Specifically, such as Figure 4 As shown, the decorative cover 9 includes a cover body 91 and a bottom decorative panel 92. The cover body 91 surrounds the main box 8 and the adapter 5, and the bottom decorative panel 92 surrounds the bottom of the adapter 5 and is fastened to the bottom of the cover body 91 and connected by screws. By disassembling the decorative cover 9 into two parts, the cover body 91 and the bottom decorative panel 92, the screw connection is hidden inside while meeting the mold forming requirements. This avoids complex processes such as welding, maintains a unified and beautiful appearance, and facilitates installation.
[0055] like Figure 5 and Figure 6 As shown, the housing 1 also includes a partition 16 located on the upper side, on which two mounting brackets 18 are fixedly connected. The two mounting brackets 18 are located on the left and right sides of the adapter 5, respectively. The surrounding panel 52 and the bottom decorative panel 92 are both fixedly connected to the mounting brackets 18 by screws. The left and right sides of the cover 91 are respectively provided with mounting protrusions 911 arranged horizontally in the front-back direction. The mounting protrusions 911 are fixedly connected to the mounting brackets 18 by fasteners such as screws or rivets.
[0056] Combination Figure 2 and Figure 5 The housing 1 also includes two top plates 15 located on the upper side. The two top plates 15 are located on the left and right sides of the adapter 5, respectively. The top plates 15 are fastened to the upper side of the partition 16 and cover the mounting bracket 18 and the mounting protrusion 911 of the cover 91. The mounting protrusion 911 of the cover 91 is installed in the horizontal direction, so that the top plate 15 can more easily hide the screw connection between the mounting protrusion 911 and the mounting bracket 18 inside, maintaining an integrated and beautiful appearance.
[0057] Optionally, regardless of whether the smoke collection chamber 2 is open or closed, the vertical projection of the bottom edge of the smoke collection chamber 2 is always within the range of the oil cup 4, so that all the oil droplets on the front side of the smoke collection chamber 2 can enter the oil cup 4. In addition, the vertical projection of the rear plate 17 of the housing 1 is also always within the range of the oil cup 4, so that all the oil droplets left on the rear plate 17 can also enter the oil cup 4.
[0058] Optionally, such as Figure 7 As shown, the range hood also includes a flap 3, the top of which is rotatably connected to the top of the smoke collection chamber 2 and can be flipped relative to the smoke collection chamber 2. In operation, the flap 3 and the smoke collection chamber 2 are open relative to the housing 1, the smoke collection chamber 2 moves out of the housing 1, achieving the same smoke extraction effect as a side-suction range hood. The flap 3 flips relative to the smoke collection chamber 2 to form a larger smoke collection area, effectively improving smoke collection efficiency, helping to prevent smoke escape, and improving kitchen cleanliness and air quality; Figure 4 As shown, in the non-working state, the flap 3 and the smoke collection chamber 2 are closed relative to the housing 1, so that the smoke collection chamber 2 is hidden inside the housing 1. The flap 3 fits and covers the front side of the housing 1, ensuring a neat and integrated appearance. This makes the structure of the range hood more compact and small when not in use, and the thickness of the housing 1 can be made thinner, thereby achieving a thinner body size and reducing the space occupied.
[0059] Optionally, the top of the flap 3 can be rotatably connected to the smoke collection chamber 2 via a hinge or hinge, without specific limitations.
[0060] like Figure 4 As shown, the front side of the casing 1 forms a vertical plane. When fully closed, the flap 3 is a flat structure extending vertically and parallel to the wall, presenting a flat appearance. This makes the range hood more compact when not in use, achieving a thinner body size and reducing space occupation. Furthermore, from the front, the flap 3 appears as a complete flat structure with no visible gaps, facilitating daily cleaning and enhancing the overall aesthetics. Its appearance is clearly distinguishable from traditional or other range hood structures in the industry. This design not only improves the user experience but also avoids the cleaning difficulties caused by the complex structure of traditional range hoods.
[0061] like Figure 4 As shown, when fully closed, the flap 3 fits and covers the front side of the housing 1 and can cover the front side of the oil cup 4, so that the oil cup 4 is hidden when not in operation, which increases the aesthetics of the appearance and helps to ensure the cleanliness of the appearance.
[0062] like Figure 7As shown, the shell 1 also includes outer side plates 12 located on the left and right sides, partition plates 16 and bottom plates 14 are arranged vertically at intervals, the bottom plate 14 is located between the two outer side plates 12, the two outer side plates 12 are respectively connected to the left and right sides of the partition plates 16 and the bottom plate 14, and the rear plate 17 is connected to the rear side of the partition plates 16, the bottom plate 14 and the outer side plates 12, thereby forming a shell 1 with a rectangular structure.
[0063] like Figure 7 As shown, the bottom of the outer side panel 12 is lower than the oil cup 4 to cover the left and right sides of the oil cup 4, so that the oil cup 4 is also hidden on the left and right sides, which is conducive to the cleanliness of the range hood's appearance and further enhances its aesthetics.
[0064] like Figure 7 and Figure 8 As shown, the front side of the smoke collection chamber 2 is provided with a first smoke inlet 221. When the smoke collection chamber 2 is fully open, the first smoke inlet 221 is tilted downwards. At this time, the angle between the front side of the smoke collection chamber 2 and the vertical direction can be selected from 20° to 40°, preferably 30°. In this way, the first smoke inlet 221 can face the stove, forming a side-suction range hood, and has a larger smoke collection area, effectively improving the smoke collection efficiency and helping to prevent smoke from escaping. When the flap 3 is fully closed, the flap 3 covers the first smoke inlet 221, which is aesthetically pleasing and neat.
[0065] Furthermore, such as Figure 8 As shown, when the flap 3 and the smoke collection chamber 2 are fully opened, an angle is formed between the flap 3 and the smoke collection chamber 2, forming a smoke gathering area. The angle ranges from 55° to 95°, preferably 77°. At this time, the smoke gathering effect of the smoke gathering area is better.
[0066] In other words, when in the open state, the smoke collection chamber 2 extends relative to the housing 1, achieving the first-level smoke collection function. Then, the flap 3 flips open relative to the smoke collection chamber 2, further expanding the smoke collection range and forming a superimposed smoke collection effect of "1+1>2". This synergistic effect not only improves the smoking efficiency but also achieves a combination of a small body size and a large smoke collection area, realizing a large smoke collection size with a relatively small smoke collection mechanism.
[0067] In this embodiment, as Figure 7 As shown, inner glass 26 is installed at both ends of the front side of the smoke collection chamber 2. Each inner glass 26 extends outward in the left and right directions, but does not exceed the left and right sides of the flap 3. The inner glass 26 on both sides not only improves the aesthetics, but also increases the smoke collection area and reduces the escape of oil fumes.
[0068] Specifically, the smoke collection chamber 2 includes a main body 21 and an oil filter 22. An installation port is provided on the front side of the main body 21, and the oil filter 22 covers the installation port. Multiple first smoke inlets 221 are provided on the oil filter 22. Cooking fumes contain a large number of grease particles. If the grease enters the fan directly, it will adhere to the motor, blades, and other core components, leading to increased operating resistance, increased noise, and even damage. The oil filter 22, as the first line of defense, filters these oil droplets through dense pores, preventing them from directly entering the range hood or adhering to the fan blades. This reduces the accumulation of grease on internal parts, resulting in cleaner filtered air and effectively reducing grease contamination of the internal ducts of the range hood and the external environment.
[0069] Optionally, in this embodiment, the oil filter 22 is magnetically attached to the main body 21 of the smoke collection chamber for easy disassembly and individual cleaning. In other optional embodiments, the oil filter 22 can also be detachably installed using snap-fit or screw connection, and no specific limitation is made here.
[0070] Optionally, two mounting ports are provided on the front side of the smoke collection chamber body 21, and the two mounting ports are arranged at intervals along the left and right direction. Each mounting port is equipped with an oil filter 22. In this way, each oil filter 22 can correspond to one stove, achieving precise smoke extraction and improving smoke extraction efficiency.
[0071] Optionally, such as Figure 7 As shown, when the smoke collection chamber 2 is opened, a second smoke inlet 11 is formed between its bottom and the bottom of the housing 1. After the flap 3 and the smoke collection chamber 2 are opened relative to the housing 1, the bottom of the smoke collection chamber 2 forms a second smoke inlet 11 between it and the housing 1, forming a three-chamber smoke intake system with the two oil filters 22, which greatly increases the air intake area of the range hood and improves the smoke extraction efficiency.
[0072] Optionally, a flexible mesh is provided at the second smoke inlet 11. One end of the flexible mesh is detachably connected to the bottom of the smoke collection chamber 2, and the other end is detachably connected to the bottom of the housing 1. When the smoke collection chamber 2 is opened, the flexible mesh is unfolded to filter the oil fumes at the second smoke inlet 11, reducing the accumulation of oil stains on the internal parts. When the smoke collection chamber 2 is closed, the flexible mesh can be folded, without affecting the closing of the smoke collection chamber 2 and the flap 3.
[0073] like Figure 9 As shown, the drive mechanism includes a first drive assembly 6 and a second drive assembly 7. When opening or closing, the first drive assembly 6 drives the flap 3 to flip relative to the smoke collection chamber 2, and the second drive assembly 7 drives the smoke collection chamber 2 to move relative to the housing 1. By driving the flap 3 and the smoke collection chamber 2 independently with two sets of drive assemblies, the stability of the movement of the flap 3 and the smoke collection chamber 2 can be ensured, and it is also beneficial to reduce the longitudinal dimension of the range hood and save kitchen space.
[0074] Specifically, the first drive assembly 6 is installed in the middle of the smoke collection chamber 2, and the second drive assembly 7 is installed on the left and right sides inside the housing 1. By reasonably setting the positions of the first drive assembly 6 and the second drive assembly 7, the space occupied by the two can be reasonably allocated, and by arranging the first drive assembly 6 and the second drive assembly 7 along the transverse side of the smoke machine, it is beneficial to reduce the longitudinal dimension of the smoke machine.
[0075] like Figure 10 As shown, the first drive assembly 6 includes a first motor 61 and a first swing arm assembly 62. The first motor 61 is disposed inside the smoke collection chamber 2. One end of the first swing arm assembly 62 is connected to the output shaft of the first motor 61, and the other end passes through the smoke collection chamber 2 and is hinged to the back of the flap 3. When the output shaft of the first motor 61 rotates, it drives the first swing arm assembly 62 to rotate, and the first swing arm assembly 62 drives the flap 3 to flip relative to the smoke collection chamber 2 to open or close. This drive structure has the advantages of simple structure, high control precision, safety and reliability, compact structure, and low maintenance cost. Optionally, in other embodiments, the first motor 61 can be replaced with a drive cylinder.
[0076] Specifically, such as Figure 10 As shown, the first swing arm assembly 62 includes a first swing arm 621 and a second swing arm 622. One end of the first swing arm 621 is connected to the output shaft of the first motor 61, and the other end is hinged to one end of the second swing arm 622. The other end of the second swing arm 622 passes through the front side of the smoke collection chamber 2 and is hinged to the back of the flap 3. Specifically, when the output shaft of the first motor 61 rotates, the first motor 61 drives the first swing arm 621 to rotate, the first swing arm 621 drives the second swing arm 622 to rotate, and the second swing arm 622 drives the flap 3 to rotate, thereby opening or closing. By adopting the above-described swing arm structure, when the flap 3 is closed, the first swing arm 621 and the second swing arm 622 are folded, occupying little space. When the flap 3 is open, the first swing arm 621 and the second swing arm 622 extend to a longer length, thereby opening the flap 3 to a specific angle to meet a larger smoke collection area.
[0077] Furthermore, combined Figures 9 to 11 The smoke collection chamber 2 has a protective cavity 24 at its rear and a through hole 211 at its front that communicates with the protective cavity 24. A first motor 61 is installed inside the protective cavity 24, as is a first swing arm 621. A second swing arm 622 passes through the through hole 211 and connects to the back of the flap 3. By installing the first motor 61 inside the protective cavity 24 at the rear of the smoke collection chamber 2, the fumes are isolated, minimizing direct contact between the fumes and the first motor 61, thus extending the service life of the first motor 61 and consequently extending the service life of the side-suction range hood.
[0078] Furthermore, such as Figure 7As shown, an elastic seal 212 is used to seal the perforation 211. The elastic seal 212 can be made of rubber. The elastic seal 212 has a slit. The second swing arm 622 passes through the slit and connects to the back of the flap 3. The slit seal is wrapped around the outside of the second swing arm 622 to prevent oil fumes from entering the protective cavity 24 through the perforation 211 and adhering to the first motor 61, which would increase its operating resistance, increase noise, or even damage it.
[0079] Furthermore, such as Figure 9 As shown, in the left-right direction, the protective cavity 24 is located in the middle of the smoke collection cavity 2, and the second swing arm 622 is connected to the middle of the back of the flap 3. This arrangement ensures that the flap 3 is subjected to uniform force, allowing the left and right sides of the flap 3 to push out synchronously when it opens, preventing jamming and ensuring the synchronicity and stability of the movement.
[0080] Furthermore, combined Figure 11 The first drive assembly 6 also includes a mounting plate 63, which includes a first plate 631, a second plate 632, and a third plate 633. The first plate 631 covers the upper opening of the protective cavity 24. The second plate 632 is connected to the first plate 631 at an angle and is located at the rear opening of the protective cavity 24. The second plate 632 abuts against the rear side of the smoke collection cavity 2 and is fastened. The third plate 633 is connected to the second plate 632 and extends into the protective cavity 24 and is fastened to the first motor 61.
[0081] First, the mounting plate 63 is used to fix the first motor 61 and covers the opening of the protective cavity 24 to isolate the oil fumes. Second, since the flap 3 is heavy, if the mounting plate 63 is not strong enough, the mounting plate 63 and the entire smoke collection cavity 2 will deform during the opening of the flap 3. Therefore, by abutting and installing the second plate 632 of the mounting plate 63 against the rear side of the smoke collection cavity 2, its structural strength can be guaranteed.
[0082] Specifically, such as Figure 11 As shown, the second plate 632 covers part of the rear opening of the protective cavity 24, and the rear opening of the protective cavity 24 not covered by the second plate 632 forms a clearance opening 25. At least part of the first motor 61 is directly opposite the second plate 632 to provide protection, and the first swing arm assembly 62 is directly opposite the clearance opening 25.
[0083] When the flap 3 is fully closed, the hinged parts of the first swing arm 621 and the second swing arm 622 after folding can extend from the clearance opening 25 to provide clearance. Secondly, when the range hood malfunctions and the flap 3 cannot be opened, the rear plate 17 of the range hood can be disassembled after the range hood is removed from the wall. The screw connecting the first swing arm 621 to the output shaft of the first motor 61 is exposed at the clearance opening 25. At this time, the worker can loosen this screw with a wrench to release the constraint on the flap 3 and allow the flap 3 to open smoothly for subsequent maintenance operations. If the first motor 61 malfunctions, the mounting plate 63 can be removed to repair or replace the first motor 61, making machine maintenance convenient.
[0084] In one optional embodiment, the smoke collection chamber 2 can only rotate relative to the housing 1.
[0085] In an optional embodiment, the smoke collection chamber 2 can only slide relative to the housing 1 in the front-rear direction.
[0086] In one optional embodiment, the smoke collection chamber 2 can rotate and slide relative to the housing 1. Specifically, the smoke collection chamber 2 can generate a sliding displacement in the horizontal or inclined direction while rotating relative to the housing 1.
[0087] In this embodiment, when the smoke collection chamber 2 is opened, the smoke collection chamber 2 flips outward relative to the housing 1 and generates an upward sliding displacement; conversely, when the smoke collection chamber is closed, the smoke collection chamber 2 flips inward relative to the housing 1 and generates a downward sliding displacement.
[0088] When the smoke collection chamber 2 is opened, it can not only rotate relative to the shell 1, but also extend the smoke collection area forward by sliding upward at an angle, thereby expanding the coverage of the smoke collection area. As the smoke collection chamber 2 extends forward, the flap 3 unfolds and adjusts its angle to further increase the smoke collection area, effectively improving the smoke collection efficiency, helping to prevent oil fumes from escaping, and improving the cleanliness and air quality of the kitchen. At the same time, the upward sliding of the smoke collection chamber 2 can also drive the flap 3 to rise as a whole, avoiding obstruction of vision and head bumping.
[0089] In this embodiment, as Figure 9 As shown, the second driving assembly 7 is used to drive the smoke collection chamber 2 to rotate relative to the housing 1 while generating a sliding displacement in the tilt direction. Specifically, the second driving assembly 7 includes a rotating component 71, a first guide component 72, and a second guide component 73. The rotating component 71 is used to drive the smoke collection chamber 2 to rotate, and the smoke collection chamber 2 slides in cooperation with the housing 1 through the first guide component 72 and the second guide component 73.
[0090] The flipping component 71 drives the smoke collection chamber 2 to flip, providing the smoke collection chamber 2 with the power to open or close, causing the smoke collection chamber 2 to extend outward from the housing 1 and reach the smoke extraction position. The smoke collection chamber 2 slides with the housing 1 through the first guide component 72 and the second guide component 73. The first guide component 72 and the second guide component 73 limit the sliding trajectory of the smoke collection chamber 2, ensuring that the smoke collection chamber 2 is stable and does not shake during the sliding process. Through the guidance of the guide components, the smoke collection chamber 2 can flip outward relative to the housing 1 when it is opened, and at the same time generate an outward sliding displacement in the tilt direction. Therefore, the smoke collection area extends forward, the smoke collection area is larger, the smoke collection efficiency is effectively improved, and it helps to prevent the escape of oil fumes and improve the air quality in the kitchen.
[0091] Specifically, such as Figure 10 and Figure 12 As shown, the flipping component 71 includes a second motor 711, a drive shaft 713, and two sets of second swing arm assemblies 712. The second motor 711 is connected to the housing 1. The drive shaft 713 extends in the left and right direction. One end of the drive shaft 713 is fixedly connected to the output shaft of the second motor 711, for example, by welding or screw fixing, and the other end passes through the housing 1. The two sets of second swing arm assemblies 712 are respectively connected to the left and right sides of the smoke collection chamber 2 and are simultaneously fixedly mounted on the drive shaft 713.
[0092] When the output shaft of the second motor 711 rotates, it drives the transmission shaft 713 to rotate. The transmission shaft 713 drives the two sets of second swing arms 712 to rotate synchronously. The two sets of second swing arms 712 cause the smoke collection chamber 2 to flip relative to the housing 1, thus opening or closing it. In this way, the second motor 711 drives the two sets of second swing arms 712 to rotate synchronously through the transmission shaft 713, which ensures that the left and right sides of the smoke collection chamber 2 move synchronously when opening or closing, ensuring the synchronicity and stability of the movement.
[0093] Specifically, such as Figure 12 and Figure 14 As shown, the second swing arm assembly 712 includes a third swing arm 7121, a fourth swing arm 7122, and a swing arm bracket 7123. The third swing arm 7121 is fixedly mounted on the drive shaft 713, for example, by welding or screw fixing. The fourth swing arm 7122 is hinged to the third swing arm 7121. The swing arm bracket 7123 is hinged to the fourth swing arm 7122 and fixedly connected to the smoke collection chamber 2.
[0094] When the output shaft of the second motor 711 rotates, it drives the transmission shaft 713 to rotate. The transmission shaft 713 then drives the third swing arm 7121 to rotate. The third swing arm 7121 transmits power sequentially through the fourth swing arm 7122 and the swing arm bracket 7123, ultimately driving the smoke collection chamber 2 to move. By adopting the above-mentioned swing arm structure, when the smoke collection chamber 2 is closed, the third swing arm 7121 and the fourth swing arm 7122 fold, occupying little space. When the smoke collection chamber 2 is open, the third swing arm 7121 and the fourth swing arm 7122 extend, thereby opening the smoke collection chamber 2 to a specific angle to meet a larger smoke collection area.
[0095] Optionally, such as Figure 9 and Figure 10 As shown, the housing 1 also includes inner side plates 13 located on the left and right sides. The inner side plates 13 are located inside the outer side plates 12, and the outer side plates 12 enclose a sealed chamber. The second motor 711 is located in one of the sealed chambers and is fixed to the inner side plate 13. By installing the second motor 711 in the sealed chamber, it can isolate oil fumes, minimize direct contact between oil fumes and the second motor 711, and extend the service life of the second motor 711.
[0096] Optionally, the smoke collection chamber 2 is provided with a first guide component 72 and a second guide component 73 on both the left and right sides to ensure that the smoke collection chamber 2 moves smoothly without shaking during the sliding process.
[0097] Specifically, such as Figure 13 As shown, the first guide component 72 is located below the second guide component 73. The first guide component 72 includes a guide bracket 721 and a guide shaft 722. The guide bracket 721 is fixed to the outer side of the inner side plate 13, and the guide shaft 722 is fixed to the side of the smoke collection chamber 2. A guide hole 7211 is provided on the guide bracket 721, and the guide shaft 722 is rotatably connected to the guide hole 7211 and can slide along the guide hole 7211. The second guide component 73 includes a guide rail 732 and a slider 731. The guide rail 732 is fixed to the inner side of the inner side plate 13, and the slider 731 can slide along the guide rail 732. The end of the slider 731 is rotatably connected to the smoke collection chamber 2.
[0098] When the second motor 711 drives the smoke collection chamber 2 to rotate via the second swing arm assembly 712, the smoke collection chamber 2 drives the slider 731 and the guide shaft 722 to move. The slider 731 rotates relative to the smoke collection chamber 2 around the hinge point while sliding along the guide rail 732. The guide shaft 722 rotates in the guide hole 7211 while sliding along the guide hole 7211. Through the coordinated action of the slider 731 and the guide shaft 722, the composite motion path of the entire smoke collection chamber 2 is determined, ensuring that the smoke collection chamber 2 is stable and does not shake during the sliding process.
[0099] Furthermore, such as Figure 10 and Figure 13 As shown, the smoke collection chamber 2 also includes a chamber reinforcement 23. The left and right ends of the smoke collection chamber body 21 are respectively connected to the chamber reinforcement 23. The guide shaft 722, the slider 731, and the swing arm bracket 7123 are all connected to the chamber reinforcement 23. The chamber reinforcement 23 strengthens the structural strength of the smoke collection chamber body 21 and prevents deformation.
[0100] Among them, such as Figure 14 As shown, the hinge axis of the swing arm bracket 7123 and the fourth swing arm 7122 is coaxial with the hinge axis of the slider 731 and the cavity reinforcement 23 to meet the motion trajectory requirements.
