Description

Technical Field

[0001] This invention relates to the field of kitchen appliance technology, and in particular to a concealed range hood. Background Technology

[0002] Traditional range hoods, typically exceeding 350mm in thickness, cannot be fully integrated into cabinets. This means they fail to achieve a seamless integration with cabinetry; whether in use or off, the range hood remains exposed on the outside. Even with frequent wiping, it's difficult to thoroughly clean the exterior, resulting in a greasy feeling in the kitchen. Furthermore, traditional side-draft range hoods, when closed, encroach on the central space above the cooktop, creating a cramped and oppressive feeling in the kitchen.

[0003] Existing concealed range hood solutions are mostly lift-type, generally falling into three categories: 1. Full lift; 2. Rear lift; 3. Lower concealed lift range hood. However, the first type of range hood creates a sense of oppression when lowered; the second type, after the flue is lowered, has the smoke inlet too far from the fan path, and the flue is thin to facilitate closer suction, resulting in poor smoke extraction. Additionally, because this ultra-thin side-suction design is on the side of the cooking fumes, the smoke collection effect is poor, leading to smoke escape; the third type, when opened, suffers from insufficient smoke extraction when using tall steamers due to its low height. Summary of the Invention

[0004] The purpose of this invention is to provide a concealed range hood that has the advantages of not causing a strong sense of oppression to the user during use, improving the smoke extraction effect, and preventing oil fumes from escaping.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This invention provides a concealed range hood, comprising a range hood body, a flip-up housing, and a smoke-gathering plate;

[0007] The bottom of the main body of the range hood has an opening;

[0008] The flip-top housing rotates with the main body of the range hood to flip the flip-top housing into or out of the opening, and a flue is formed between the flip-top housing and the main body of the range hood. The flip-top housing has a smoke inlet that communicates with the flue.

[0009] The smoke-gathering plate is movably connected to the flip-up housing to block or release the smoke-gathering port and gather the smoke below the smoke-gathering port.

[0010] Furthermore, a first drive mechanism for driving the rotating housing to rotate relative to the main body of the range hood is provided between at least one side of the main body of the range hood and the rotating housing;

[0011] And / or, a second driving mechanism for driving the smoke-gathering plate to rotate relative to the flipping housing is provided between the flipping housing and the smoke-gathering plate.

[0012] Furthermore, the first drive mechanism includes a first power source, a first engagement structure, and a second engagement structure;

[0013] One of the first power source and the second meshing structure is installed in the main body of the smoke machine, and the other is installed in the flip-over housing;

[0014] The first meshing structure is connected to the power output end of the first power source, and the first meshing structure meshes with the second meshing structure.

[0015] Furthermore, the second meshing structure includes a housing and a rack;

[0016] The cover is installed inside the flip-up housing, the cover has an engagement cavity, the engagement cavity has a side opening, and the side opening is disposed facing the inner wall of the flip-up housing;

[0017] The rack is installed in the meshing cavity, and the first meshing structure extends into the meshing cavity and meshes with the rack.

[0018] Furthermore, one end of the flip-top housing is rotatably engaged with the main body of the smoke hood, and the other end of the flip-top housing has a first arc surface, the axis of which coincides with the rotation axis of the flip-top housing;

[0019] The main body of the smoke hood is provided with a limiting structure. The surface of the limiting structure facing the flip shell has a second arc surface that matches the shape of the first arc surface. The limiting structure is used to limit the angle at which the flip shell flips into the opening.

[0020] Furthermore, the main body of the smoke hood includes a main housing and a fan installed inside the main housing;

[0021] The flip-top housing rotates and engages with the main housing to form the flue between them. The flip-top housing is positioned opposite to the fan, and the surface of the flip-top housing facing the fan has an opening to avoid the fan.

[0022] Furthermore, the flip-up housing includes an outer shell, an oil filter, and a quick-release assembly. The oil filter has the smoke inlet and is detachably connected to the outer shell via the quick-release assembly.

[0023] Furthermore, the outer casing has a snap-fit ​​groove assembly, and the quick-release assembly is installed on the oil mesh. The quick-release assembly includes a first snap-fit ​​portion and a second snap-fit ​​portion that are slidably connected within the snap-fit ​​groove assembly to jointly define the position of the oil mesh relative to the outer casing. The first snap-fit ​​portion and the second snap-fit ​​portion are slidably disposed within the quick-release assembly in the same direction so that they can move towards each other and disengage from the snap-fit ​​groove assembly under the action of an external force.

[0024] Furthermore, it also includes an oil cup assembly, which is mounted on the flip-up housing and located at the end of the flip-up housing opposite to the rotating engagement of the main body of the range hood;

[0025] The oil cup assembly has an oil inlet on its top surface facing the flip-up housing. When the flip-up housing is flipped into the opening, the top surface extends obliquely upward in a direction gradually moving away from the rotation axis of the flip-up housing, and / or, the installation direction of the oil cup assembly extends obliquely upward in a direction gradually moving away from the rotation axis of the flip-up housing.

[0026] Furthermore, it also includes an oil cup assembly, which includes a connecting component and a plurality of sub-oil cups arranged side by side. At least one of the sub-oil cups is detachably connected to the flip-up housing. Two adjacent sub-oil cups are connected by a connecting component, and the length of the connecting component is adjustable along the arrangement direction of the plurality of sub-oil cups.

[0027] When the adapter assembly is adjusted to the first limit length, the adapter assembly keeps two adjacent sub-oil cups in a flat state; when the adapter assembly is adjusted to the second limit length, the adapter assembly allows at least one adjacent sub-oil cup to rotate, so as to achieve the folding of two adjacent sub-oil cups.

[0028] Furthermore, the adapter assembly includes an adapter housing and a fixing assembly. The adapter housing is connected to one of the sub-oil cups via one of the fixing assemblies, and the adapter housing is connected to another sub-oil cup via another fixing assembly or directly.

[0029] One end of the fixing component is connected to the sub-oil cup, and the other end is slidably connected to the adapter shell along the arrangement direction of the multiple sub-oil cups;

[0030] When the adapter assembly is adjusted to the first limit length, the fixing assembly slides to engage with the adapter shell; when the adapter assembly is adjusted to the second limit length, the fixing assembly slides to rotatably connect with the adapter shell.

[0031] Furthermore, the main body of the smoke hood is equipped with a smoke sensor and / or a hand gesture sensor.

[0032] The concealed range hood provided by this invention can produce the following beneficial effects:

[0033] When cooking fumes or steam are generated during use, the flip-top casing can be opened to allow the smoke-gathering plate to reposition, thus opening the smoke inlet and concentrating the fumes below it. The fumes then enter the flue and are expelled. After use, the flip-top casing can be closed again, and the smoke-gathering plate can be reset to cover the smoke inlet, reducing the space occupied by the range hood.

[0034] The concealed range hood provided by this invention achieves its concealment effect by flipping. Compared with existing range hoods that include lifting structures, it has the following advantages: 1. It does not use a whole-body lifting mechanism during use, thus avoiding a strong sense of oppression for the user; 2. The thickness of the flue inlet does not change before or after flipping, meaning the size of the smoke inlet is not affected by the flipping action. At the same time, the height of part of the smoke inlet will not be too low after flipping, improving the smoke extraction effect; 3. The smoke gathering plate can gather the smoke below the smoke inlet, making it difficult for fumes to escape. Attached Figure Description

Detailed Implementation

[0071] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0072] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, 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 the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0073] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0074] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0075] This embodiment provides a concealed range hood, such as Figure 1 and Figure 2 As shown, the device includes a main body 1, a flip-up housing 2, and a smoke-gathering plate 3. The bottom of the main body 1 has an opening 121. The flip-up housing 2 is rotatably connected to the main body 1 so that the flip-up housing 2 flips into or out of the opening 121. A flue is formed between the flip-up housing 2 and the main body 1. The flip-up housing 2 has a smoke inlet that communicates with the flue. The smoke-gathering plate 3 is movably connected to the flip-up housing 2 to block or release the smoke inlet and gather the smoke below the smoke inlet.

[0076] When using, such as Figure 1 As shown, the flip-top housing 2 is currently in a stopped state, flipped into the opening 121, and the smoke-collecting plate 3 blocks the smoke inlet, reducing the space occupied by the smoke machine; when it is necessary to extract the smoke, as... Figure 2As shown, the flipped housing 2 flips out the opening 121, the smoke collecting plate 3 releases the smoke inlet and gathers the oil vapor to the bottom of the smoke inlet, the range hood is in use, and the smoke can enter the flue from the smoke inlet and be discharged.

[0077] The concealed range hood provided in the above embodiments does not adopt an overall lifting mechanism, so it will not give users a strong sense of oppression. The size of the plane where the smoke inlet is located will not change before and after flipping. At the same time, the height of part of the smoke inlet will not be too low after flipping, thus improving the smoke extraction effect. Meanwhile, the smoke collection plate has a smoke collection effect, making it difficult for oil fumes to escape.

[0078] The rotation of the flip-top housing 2 can be achieved manually by the user. In this case, the limiting of the flip-top housing 2 can be achieved through the locking structure between the main body 1 and the flip-top housing 2. The locking structure can include slots and blocks. The main body 1 of the range hood has multiple slots, and the flip-top housing 2 has blocks that can be locked into any one of the slots. The rotation of the flip-top housing 2 can also be achieved automatically, for example, by rotating the flip-top housing 2 with a rotating motor, or by the cooperation of a rotating motor and a transmission mechanism.

[0079] In some embodiments, for ease of user operation, such as Figure 3 As shown, at least one side of the main body 1 of the range hood is provided with a first drive mechanism 4 for driving the rotating housing 2 to rotate relative to the main body 1 of the range hood.

[0080] In at least one embodiment, such as Figure 3 As shown, a first drive mechanism 4 is provided between both sides of the flip-up housing 2 and the main body 1 of the range hood. The two first drive mechanisms 4 are used to jointly drive the flip-up housing 2 to rotate relative to the main body 1 of the range hood. The two first drive mechanisms 4 can ensure the same rotation speed, so that the left and right sides of the flip-up housing 2 rotate together, thus preventing the flip-up housing 2 from getting stuck due to different rotation angles on both sides because the distance between the two sides of the flip-up housing 2 is large.

[0081] The structure of the first drive mechanism 4 is described in detail below:

[0082] In some embodiments, the first drive mechanism 4 includes a first power source 41, a first engagement structure 42, and a second engagement structure 43. One of the first power source 41 and the second engagement structure 43 can be installed on the main body 1 of the range hood, and the other can be installed on the flip-up housing 2.

[0083] by Figure 4 Taking this example, the first power source 41 can be installed inside the main body 1 of the smoke machine through the power source mounting bracket 14; the first meshing structure 42 is connected to the power output end of the first power source 41, and the first meshing structure 42 meshes with the second meshing structure 43; the second meshing structure 43 can be installed inside the flip-up housing 2 with screws.

[0084] The first drive mechanism 4 uses meshing transmission to achieve more precise control, thereby making the rotation speed and rotation angle of the flip shell 2 more accurate.

[0085] In some embodiments, such as Figure 5 As shown, the second meshing structure 43 includes a housing 431 and a rack 432, wherein:

[0086] The bottom end of the cover 431 can be installed in the flip housing 2 by screws. The cover 431 has a meshing cavity 4311 with a side opening 121 facing the inner wall of the flip housing 2.

[0087] The rack 432 is installed in the meshing cavity 4311, and the first meshing structure 42 extends into the meshing cavity 4311 and meshes with the rack 432.

[0088] The aforementioned cover 431 adopts a shell-like structure to shield the portion of the rack 432 that meshes with the first meshing structure 42. During operation, the front wall of the cover 431 effectively shields the fumes entering the smoke chamber 24 inside the flip-over housing 2, minimizing the erosion of the meshing area by the fumes; at the same time, the shell-like structure can cover the meshing teeth, reducing the noise generated by the meshing transmission.

[0089] Specifically, such as Figure 5 As shown, the cross-section of the cover 431 is fan-shaped and perpendicular to the rotation axis of the flip-over housing 2. The rack 432 is mounted on the rear wall of the cover 431, and the rack 432 is curved into an arc shape, with the axis of the arc shape coinciding with the rotation axis of the flip-over housing 2.

[0090] It should be noted that the "front wall" mentioned above refers to the wall away from the mounting wall after the cover 431 is installed; the "rear wall" mentioned above refers to the wall close to the mounting wall after the cover 431 is installed.

[0091] In some embodiments, such as Figures 4 to 6 As shown, the first power source 41 can be a damping motor, and the power output shaft of the damping motor is fixedly connected to the first meshing structure 42. The first meshing structure 42 can be a gear, and the gear extends into the meshing cavity 4311 to mesh with the rack 432 in the second meshing structure 43.

[0092] Because the damping motor rotates precisely, and with the superior precision angle transmission of the first meshing structure 42 and the second meshing structure 43, the rotation speed and rotation angle of the flip shell 2 can be made more accurate.

[0093] The structure of the flip-up housing 2 is described in detail below:

[0094] In some embodiments, one end of the flip-up housing 2 is rotatably engaged with the main body 1 of the range hood, such as... Figure 7 As shown, the other end of the flip shell 2 has a first arc surface 2111, and the axis of the first arc surface 2111 coincides with the rotation axis of the flip shell 2.

[0095] During use, the front end of the flip-top housing 2 is rotatably connected to the inside of the range hood body 1, and the rear end face (first arc surface 2111) of the flip-top housing 2 rotates relative to the inner wall of the range hood body 1. Since the axis of the first arc surface 2111 coincides with the rotation axis of the flip-top housing 2, the distance between the first arc surface 2111 and the inner wall of the range hood body 1 remains constant. The first arc surface 2111 will not gradually move away from the inner wall of the range hood body 1 due to the rotation of the flip-top housing 2, thus preventing the formation of a large gap. Nor will the first arc surface 2111 interfere with the inner wall of the range hood body 1 due to the rotation of the flip-top housing 2, ensuring that the smoke can smoothly enter the range hood body 1 through the smoke inlet.

[0096] In some embodiments, such as Figure 3 As shown, the flip-top housing 2 includes an outer shell 21, which includes a side wall assembly 211 and a bottom wall 212 connected to the bottom of the side wall assembly 211. One end of the side wall assembly 211 is rotatably connected to the front end of the main body 1 of the smoke hood, and this end has a third arc surface 2112 that is opposite to the first arc surface 2111. The axis of the third arc surface 2112 coincides with the rotation axis of the flip-top housing 2. The other end of the side wall assembly 211 has the first arc surface 2111.

[0097] The aforementioned third arc surface 2112 ensures that the distance between the third arc surface 2112 and the inner wall of the opposite range hood body 1 remains unchanged during the rotation of the flip shell 2. This, in conjunction with the first arc surface 2111, guarantees the sealing between the flip shell 2 and the inner wall of the range hood body 1, preventing large gaps or interference between the two.

[0098] In some embodiments, when the flip-over housing 2 includes a sidewall assembly 211 and a bottom wall 212 connected to the bottom of the sidewall assembly 211, as... Figure 7 As shown, the side wall assembly 211 can have a clearance opening 2113 on the surface away from the bottom wall 212. The clearance opening 2113 can avoid some of the internal structure of the range hood body 1 when the flip shell 2 is in the stopped state. When the flip shell 2 flips into the range hood body 1, it will not collide with the internal structure of the range hood body 1, thereby making the internal structure of the range hood body 1 more compact.

[0099] Based on the above embodiments, such as Figure 7As shown, the bottom wall 212 of the flip-top housing 2 can form a smoke chamber 24 with the side wall assembly 211, and the bottom wall 212 has smoke inlets. An oil mesh 22 can be installed on the bottom wall 212 of the flip-top housing 2, and the oil mesh 22 forms multiple smoke inlets.

[0100] In at least one embodiment, the cross-section of the smoking chamber 24 is fan-shaped and the cross-section is perpendicular to the rotation axis of the flip-over housing 2.

[0101] In some embodiments, such as Figure 8 and Figure 9 As shown, the flip-top housing 2 also includes an oil filter 22 and a quick-release assembly 23. The oil filter 22 has a smoke inlet. To facilitate cleaning of the oil filter 22, the oil filter 22 is detachably connected to the flip-top housing 2 via the quick-release assembly 23.

[0102] Specifically, such as Figure 8 As shown, the quick-release assembly 23 can be installed on the oil filter 22. The quick-release assembly 23 includes a first snap-fit ​​portion 231 and a second snap-fit ​​portion 232 that are slidably connected in the snap-fit ​​groove group 213 to jointly define the position of the oil filter 22 relative to the outer shell 21. The first snap-fit ​​portion 231 and the second snap-fit ​​portion 232 are slidably disposed in the quick-release assembly 23 in the same direction so that they can move towards each other and disengage from the snap-fit ​​groove group 213 under the action of external force.

[0103] When using the above-mentioned quick-release oil mesh, the first locking part 231 and the second locking part 232 simultaneously engage with the flip-top housing 2, jointly defining the position of the oil mesh 22 relative to the flip-top housing 2; when it is necessary to disassemble the oil mesh 22, an external force is applied to the first locking part 231 and the second locking part 232, causing the first locking part 231 and the second locking part 232 to move towards each other and simultaneously disengage from the flip-top housing 2, thereby realizing the disassembly of the oil mesh 22.

[0104] Because the quick-release assembly 23 has a first latching part 231 and a second latching part 232 that jointly define the position of the oil screen 22 relative to the flip-out housing 2, the oil screen cannot be removed from the range hood body by applying external force to only one latching part. Both the first latching part 231 and the second latching part 232 need to be pressed together to remove the oil screen. This can effectively prevent the oil screen from falling off due to misoperation and causing safety problems.

[0105] In some embodiments, such as Figure 10 As shown, at least one surface of the first snap-fit ​​part 231 that contacts the flip-top housing 2 has a first sound-absorbing layer 2311. The first sound-absorbing layer 2311 ensures that no extra noise is generated during the operation of the range hood due to the collision between the first snap-fit ​​part 231 and the flip-top housing 2.

[0106] In at least one embodiment, each surface of the first snap-fit ​​portion 231 that contacts the flip-out housing 2 has a first sound-absorbing layer 2311.

[0107] In some embodiments, such as Figure 10 As shown, at least one surface of the second snap-fit ​​portion 232 that contacts the flip-top housing 2 has a second sound-absorbing layer 2321. The second sound-absorbing layer 2321 ensures that no extra noise is generated during the operation of the smoke machine due to the collision between the second snap-fit ​​portion 232 and the flip-top housing 2.

[0108] In at least one embodiment, each surface of the second snap-fit ​​portion 232 that contacts the flip-out housing 2 has a second sound-absorbing layer 2321.

[0109] In some embodiments, such as Figure 10 and Figure 11 As shown, the end of the first latching portion 231 facing the second latching portion 232 has a first insertion end 2312, and the end of the second latching portion 232 facing the first latching portion 231 has a second insertion end 2322; the first insertion end 2312 and the second insertion end 2322 are inserted into each other, and the first insertion end 2312 slides in the direction of sliding of the first latching portion 231 with the second insertion end 2322.

[0110] When the first latching part 231 and the second latching part 232 are pressed, since the first plug-in end 2312 and the second plug-in end 2322 are plugged in and can slide relative to each other, the first plug-in end 2312 and the second plug-in end 2322 can play a guiding role, ensuring the stability of the relative position of the first latching part 231 and the second latching part 232 during installation and use.

[0111] Specifically, the first plug-in terminal 2312 can be plugged into the second plug-in terminal 2322, or the second plug-in terminal 2322 can be plugged into the first plug-in terminal 2312.

[0112] In at least one embodiment, the first plug-in end 2312 includes a cylindrical protrusion, and the end face of the second plug-in end 2322 has a cylindrical insertion hole. The cylindrical protrusion is inserted into the cylindrical insertion hole and can slide relative to the cylindrical insertion hole, allowing the first latching part 231 and the second latching part 232 to move towards each other and backward.

[0113] In some embodiments, such as Figure 10 and Figure 11 As shown, an elastic element 233 is provided between the first locking portion 231 and the second locking portion 232. When the oil filter needs to be installed, the first locking portion 231 and the second locking portion 232 move towards each other under the action of external force, aligning the first locking portion 231 and the second locking portion 232 with the locking position on the flip-up housing 2. Then, the first locking portion 231 and the second locking portion 232 are released, and the elastic element 233 can provide a restoring force for the first locking portion 231 and the second locking portion 232, so that the first locking portion 231 and the second locking portion 232 are locked onto the flip-up housing 2.

[0114] The aforementioned elastic element 233 can be a spring, a sheet, or the like.

[0115] When the first latching portion 231 has a first insertion end 2312 and the second latching portion 232 has a second insertion end 2322, such as Figure 11 As shown, the elastic element 233 can be sleeved on the outside of the first insertion end 2312 and the second insertion end 2322.

[0116] During installation, the elastic element 233 is first fitted onto the first insertion end 2312, then the first insertion end 2312 is inserted into the second insertion end 2322, and then the combined structure of the first latching part 231, the second latching part 232, and the elastic element 233 is placed into the quick-release assembly 23. The first insertion end 2312 and the second insertion end 2322 make the above-mentioned combined structure more stable when placed into the quick-release assembly 23, and the elastic element 233 will not easily pop out (because the elastic element 233 will be in a compressed state during installation); in use, the first insertion end 2312 and the second insertion end 2322 can limit the position of the elastic element 233, ensuring that the elastic element 233 can be stably placed between the first latching part 231 and the second latching part 232.

[0117] In some embodiments, such as Figure 10 and Figure 11 As shown, the quick-release assembly 23 also includes a quick-release housing 234 connected to the oil mesh 22. The quick-release housing 234 can be installed on the oil mesh 22 by means of screws or other connectors.

[0118] Specifically, such as Figure 11 As shown, the quick-release housing 234 has a sliding cavity 2341 inside; one end of the first locking part 231 extends into the sliding cavity 2341 and slides into the sliding cavity 2341, and the other end is used to lock into the flip housing 2; one end of the second locking part 232 extends into the sliding cavity 2341 and slides into the sliding cavity 2341, and the other end is used to lock into the flip housing 2.

[0119] The sliding cavity 2341 guides the sliding of the first locking part 231 and the second locking part 232, and can accommodate the end of the first locking part 231, the end of the second locking part 232 and the elastic member 233.

[0120] Specifically, such as Figure 10 and Figure 11 As shown, the quick-release housing 234 may include an upper housing 2342 and a lower housing 2343; the lower housing 2343 has multiple connecting feet, each of which has a connecting hole for screws to pass through, and is connected to the oil mesh 22 by screws; the upper housing 2342 is fastened to the lower housing 2343 by screws and other connecting parts, and a sliding cavity 2341 is formed between the upper housing 2342 and the lower housing 2343.

[0121] In some embodiments, such as Figure 10 and Figure 11 As shown, one of the first snap-fit ​​portion 231 and the inner wall of the quick-release housing 234 is recessed with a first groove 2313, and the other has a first protrusion 2344 that extends into and slides into the first groove 2313.

[0122] The sliding engagement of the first groove 2313 and the first protrusion 2344 can further ensure that the first locking part 231 will not swing left and right in the sliding cavity 2341, thereby ensuring that the first locking part 231 will not get stuck due to left and right swinging during sliding.

[0123] In some embodiments, such as Figure 10 and Figure 11 As shown, one of the second snap-fit ​​portion 232 and the inner wall of the quick-release housing 234 is recessed with a second sliding groove 2323, and the other has a second protrusion 2345 that extends into and slides into the second sliding groove 2323.

[0124] The sliding engagement of the second groove 2323 and the second protrusion 2345 can further ensure that the second locking part 232 will not swing left and right in the sliding cavity 2341, thereby ensuring that the second locking part 232 will not get stuck due to left and right swinging during sliding.

[0125] In at least one embodiment, such as Figure 10 As shown, the first snap-fit ​​portion 231 is recessed with a first sliding groove 2313, the inner wall of the quick-release housing 234 has a first protrusion 2344, the second snap-fit ​​portion 232 is recessed with a second sliding groove 2323, and the inner wall of the quick-release housing 234 has a second protrusion 2345.

[0126] In some embodiments, such as Figure 10 As shown, to facilitate user operation, the quick-release assembly 23 also includes a first pressing rod 235. One end of the first pressing rod 235 is inserted into one end of the first latching part 231 and extends into one end of the quick-release housing 234, while the other end extends out of the quick-release housing 234 for the user to hold.

[0127] In use, the user can slide the first locking part 231 by pressing the first lever 235, which facilitates the user's operation.

[0128] Specifically, the first locking portion 231 may be recessed with an insertion hole, and the first pressing rod 235 extends into the insertion hole and is fixedly connected to the first locking portion 231 by a screw. In this way, when the user presses the first pressing rod 235, the screw between the first pressing rod 235 and the first locking portion 231 will not be subjected to lateral shear force, avoiding the screw from loosening after long-term use, which would cause the first pressing rod 235 to loosen.

[0129] In some embodiments, such as Figure 10 As shown, the surface of the first pressing rod 235 opposite to the second pressing rod 236 is recessed with a first groove 2351 for accommodating fingers. The first groove 2351 can provide friction and limit when the user grasps the first pressing rod 235 to prevent the hand from slipping and falling.

[0130] The first pressing lever 235 protrudes 15mm from the quick-release housing and has a width of 13mm, giving it a sufficiently large pressing area. This allows it to act as a gripper for removing the oil filter 22 while the user presses the first pressing lever 235.

[0131] In some embodiments, such as Figure 10 As shown, the quick-release housing 234 is provided with a first through groove 2346 for the first pressing rod 235 to pass through. The first through groove 2346 is used to limit the travel of the first pressing rod 235, thereby indirectly limiting the length of the first latching part 231 extending out of the quick-release housing 234 and the depth of entering the quick-release housing 234.

[0132] In some embodiments, such as Figure 10 As shown, for ease of user operation, the quick-release assembly 23 also includes a second pressing rod 236. One end of the second pressing rod 236 is inserted into the second latching part 232 and extends into one end of the quick-release housing 234, while the other end extends out of the quick-release housing 234. The second pressing rod 236 has a recessed second groove for accommodating a finger. The structure of the second pressing rod 236 is similar to that of the first pressing rod 235, and the connection method between the second pressing rod 236 and the second latching part 232 is similar to the connection method between the first pressing rod 235 and the first latching part 231. For the sake of brevity, these details will not be elaborated further here.

[0133] When the quick-release assembly 23 includes both the first pressing rod 235 and the second pressing rod 236, the second pressing rod 236, when used in conjunction with the first pressing rod 235, allows the user to simultaneously achieve the opposite movement of the first locking part 231 and the second locking part 232. At the same time, the second pressing rod 236 and the first pressing rod 235 can serve as grippers for removing the oil filter 22, making it easier for the user to apply force.

[0134] In some embodiments, the quick-release housing 234 is provided with a second through groove 2347 for the second pressing rod 236 to pass through. The second through groove 2347 is used to limit the travel of the second pressing rod 236, thereby indirectly limiting the length of the second latching portion 232 extending out of the quick-release housing 234 and the depth of the second latching portion 232 entering the quick-release housing 234.

[0135] like Figure 10As shown, when the quick-release housing 234 has a first through groove 2346, the lengths of the first through groove 2346 and the second through groove 2347 are the same, and the distance between the first through groove 2346 and the left end of the quick-release housing 234 is equal to the distance between the second through groove 2347 and the right end of the quick-release housing 234. This ensures that when the first pressing rod 235 and the second pressing rod 236 press towards each other, the first locking part 231 and the second locking part 232 will not have one part displace more than the other, thus preventing the oil screen 22 from being unable to be removed.

[0136] In at least one embodiment, the lengths of the first through groove 2346 and the second through groove 2347 are both equal to the lengths of the first latching portion 231 extending out of the quick-release housing 234 and the lengths of the second latching portion 232 extending out of the quick-release housing 234, such that when the first pressing rod 235 and the second pressing rod 236 are pressed to their limit positions, the first latching portion 231 and the second latching portion 232 are just fully inserted into the quick-release housing 234.

[0137] It should be noted that when the first locking part 231 and the second locking part 232 are reset under the action of the elastic member 233, the distance between the first locking part 231 and the second locking part 232 is greater than the sum of the lengths of the first through groove 2346 and the second through groove 2347.

[0138] In some embodiments, the flip-up housing 2 has a snap-fit ​​groove group 213, and the first snap-fit ​​portion 231 and the second snap-fit ​​portion 232 in the quick-release assembly 23 are both slidably snapped into the snap-fit ​​groove group 213.

[0139] When the first snap-fit ​​part 231 and the second snap-fit ​​part 232 snap into the snap-fit ​​groove group 213, the oil mesh 22 can be connected to the flip-up housing 2; when the first snap-fit ​​part 231 and the second snap-fit ​​part 232 simultaneously exit the snap-fit ​​groove group 213, the oil mesh 22 can be disassembled.

[0140] like Figure 8 As shown, the snap-fit ​​slot assembly 213 may include a first snap-fit ​​slot 2131 and a second snap-fit ​​slot 2132 disposed opposite to each other. The first snap-fit ​​portion 231 can slide into the first snap-fit ​​slot 2131, and the second snap-fit ​​portion 232 can slide into the second snap-fit ​​slot 2132. When the first snap-fit ​​portion 231 extends into the first snap-fit ​​slot 2131 and the second snap-fit ​​portion 232 extends into the second snap-fit ​​slot 2132, it can be regarded as the first snap-fit ​​portion 231 and the second snap-fit ​​portion 232 snapping into the snap-fit ​​slot assembly 213.

[0141] The flip-out housing 2 has a first U-shaped fastener and a second U-shaped fastener. A first snap-fit ​​groove 2131 is formed between the first U-shaped fastener and the inner wall of the flip-out housing 2, and a second snap-fit ​​groove 2132 is formed between the second U-shaped fastener and the inner wall of the flip-out housing 2.

[0142] In some embodiments, an oil cup assembly 6 is also snapped into the bottom of the flip-top housing 2. The oil cup assembly 6 is installed on the end of the flip-top housing 2 that is rotatably engaged with the main body 1 of the range hood, so as to receive oil stains.

[0143] like Figures 12 to 14 As shown, the oil cup assembly 6 has an oil inlet 611 on the top surface 61 facing the flip-over housing 2. When the flip-over housing 2 is flipped into the opening 121, the top surface 61 extends obliquely upward in a direction that gradually moves away from the rotation axis of the flip-over housing 2.

[0144] The rotation axis of the flip-over housing 2 is set as the first axis. For example... Figure 12 As shown, in the stopped state, the top surface 61 of the oil cup assembly 6 extends obliquely upward in a direction gradually moving away from the first axis (since the oil surface is always parallel to the horizontal plane, the end of the top of the oil cup assembly 6 away from the first axis is not filled with oil at this time). Figure 13 As shown, after the oil cup assembly 6 is flipped to the working state, the oil inside the oil cup assembly 6 can spread to the top of the oil cup assembly 6 away from the first axis, and will not overflow from the cup body. This ensures that the oil inside the oil cup assembly 6 will not overflow when the orientation of the oil inlet 611 changes, and is suitable for range hoods where the orientation of the oil inlet 611 changes.

[0145] In some embodiments, the top surface 61 of the oil cup assembly 6 may be inclined relative to the bottom surface 64 of the oil cup assembly 6, and when the oil cup assembly 6 is in a stopped state, the bottom surface 64 of the oil cup assembly 6 is parallel to the horizontal plane.

[0146] In some embodiments, when the oil cup assembly 6 is in use, the top surface 61 of the oil cup assembly 6 can be parallel to the horizontal plane, so as to make full use of the internal space of the oil cup assembly 6.

[0147] Specifically, the oil cup assembly 6 may include four side cup walls connected in sequence and a bottom cup wall connected to the bottom of the four side cup walls. The bottom cup wall is set perpendicular to the four side cup walls. An oil inlet 611 is formed between the top surfaces of the four side cup walls. The height of the side cup wall at the front end is lower than the height of the side cup wall at the rear end, and the height of the side cup wall between them gradually increases from front to back.

[0148] It is understandable that the aforementioned "front end" can be regarded as the end of the oil cup assembly 6 that is away from the mounting wall after installation, and the aforementioned "rear end" can be regarded as the end of the oil cup assembly 6 that is close to the mounting wall after installation.

[0149] In some embodiments, the snap-fit ​​direction (i.e., the installation direction) of the oil cup assembly 6 extends obliquely upward along a direction gradually moving away from the rotation axis of the flip-up housing 2. During installation, the oil cup assembly 6 can be installed and snapped in from the rear top to the front bottom. During disassembly, it needs to be moved obliquely rear and upward to remove the oil cup. Thus, even if the oil cup is accidentally touched during the use of the range hood, it will not fall off.

[0150] like Figure 14 As shown, the top surface 61 of the oil cup assembly 6 is connected to a first snap-fit ​​structure 65. The first snap-fit ​​structure 65 is used to snap into the flip-over housing 2. When the oil cup assembly 6 is in a stopped state, the snap-fit ​​direction of the first snap-fit ​​structure 65 extends obliquely upward along a direction that gradually moves away from the first axis.

[0151] The top surface 61 of the oil cup assembly 6 can be connected to one first snap-fit ​​structure 65, or to two, three, or more first snap-fit ​​structures 65.

[0152] In at least one embodiment, the top surface 61 of the oil cup assembly 6 is connected to two first snap-fit ​​structures 65. The two first snap-fit ​​structures 65 are respectively connected to both ends of the oil cup assembly 6.

[0153] In some embodiments, such as Figure 14 As shown, the snapping direction of the first snap-fit ​​structure 65 is parallel to the top surface 61 of the oil cup assembly 6. When the oil cup assembly 6 is snapped onto the flip-top housing 2, the above arrangement easily ensures that the top surface 61 of the oil cup assembly 6 can abut against the bottom surface of the flip-top housing 2, making the range hood more aesthetically pleasing.

[0154] Specifically, such as Figure 14 As shown, the first snap-fit ​​structure 65 may include a plug plate 651, which is connected to the inner wall of the oil cup assembly 6 and located at the oil inlet 611.

[0155] The insert plate 651 has a snap-fit ​​protrusion 6511 protruding towards the internal space of the oil cup assembly 6, or the insert plate 651 has a snap-fit ​​protrusion 6511 protruding away from the internal space of the oil cup assembly 6. The snap-fit ​​protrusion 6511 can snap onto the bottom of the flip-up housing 2.

[0156] In at least one embodiment, the insert plate 651 has a snap-fit ​​protrusion 6511 protruding toward the internal space of the oil cup assembly 6, and the snap-fit ​​protrusion 6511 can be formed by a spring tab.

[0157] In some embodiments, such as Figure 14 As shown, the bottom surface of the bottom wall 212 of the flip-top housing 2 includes an oil-absorbing surface 2121 and a mounting surface 2122 connected to each other. The oil-absorbing surface 2121 has a smoke inlet for absorbing smoke. The mounting surface 2122 is used to install the oil cup assembly 6 and is arranged opposite to the top surface 61 of the oil cup assembly 6. The oil-absorbing surface 2121 and the mounting surface 2122 are arranged at an angle, which is an obtuse angle.

[0158] The angle between the oil-absorbing surface 2121 and the mounting surface 2122 allows a clearance structure to be formed at the mounting surface 2122 of the flip-top housing 2 to accommodate the top surface 61 of the oil cup assembly 6, which gradually rises in a direction away from the first axis. This facilitates the installation of the oil cup assembly 6 and makes the combined structure of the oil cup assembly 6 and the flip-top housing 2 more compact.

[0159] When the oil cup assembly 6 is installed on the mounting surface 2122, the top surface 61 of the oil cup assembly 6 is parallel to and abuts against the mounting surface 2122.

[0160] In some embodiments, to facilitate the disassembly and assembly of the cup body, the bottom wall 212 of the flip-out housing 2 is connected to a second snap-fit ​​structure 25, which engages with the first snap-fit ​​structure 65 on the oil cup assembly 6.

[0161] like Figure 15 As shown, the direction indicated by the arrow is the snapping direction of the first snap-fit ​​structure 65, which is parallel to the top surface 61 of the oil cup assembly 6.

[0162] In some embodiments, the second snap-fit ​​structure 25 includes a snap plate, which can be connected to the mounting surface 2122 of the flip-up housing 2 by means of welding, screw connection or other means. The snap plate can form a slot between itself and the mounting surface 2122 of the flip-up housing 2 for engaging with the first snap-fit ​​structure 65.

[0163] In the above embodiments, the oil cup assembly 6 may include only one elongated oil cup, or it may include multiple sub-oil cups 62 connected side by side, and the multiple sub-oil cups 62 may have the same shape.

[0164] In some other embodiments, the oil cup assembly 6 includes a connecting component 63 and a plurality of sub-oil cups 62 arranged side by side. At least one sub-oil cup 62 is detachably connected to the flip-up housing 2. Two adjacent sub-oil cups 62 are connected by the connecting component 63. The connecting component 63 can fold the plurality of sub-oil cups 62, thereby shortening the length of the oil cup assembly 6 and facilitating the cleaning of the oil cup assembly 6.

[0165] Specifically, such as Figures 16 to 18 As shown, the length of the adapter component 63 is adjustable along the arrangement direction of the multiple sub-oil cups 62. When the adapter component 63 is adjusted to the first limit length, the adapter component 63 keeps two adjacent sub-oil cups 62 in a flat state, which facilitates the installation of the oil cup assembly 6. When the adapter component 63 is adjusted to the second limit length, the adapter component 63 allows at least one adjacent sub-oil cup 62 to rotate, so as to realize the folding of two adjacent sub-oil cups 62, thereby shortening the length of the oil cup assembly 6 and making it easier for users to clean.

[0166] In some embodiments, such as Figure 16As shown, the adapter 63 is connected to the side wall of two adjacent sub-oil cups 62. Compared with the adapter 63 being connected to the bottom wall of two adjacent sub-oil cups 62, it allows the oil inlets of the two adjacent sub-oil cups 62 to face the same direction after folding. When cleaning, the folded oil cups can be inverted in the dishwasher (oil inlet facing down), which is beneficial for cleaning the folded oil cups.

[0167] Based on the above embodiments, when the adapter component 63 is adjusted to the first limit length, such as Figure 16 As shown, the ends of two adjacent sub-oil cups 62 abut against each other; when the adapter assembly 63 is adjusted to the second limit length, as... Figure 17 As shown, the ends of two adjacent sub-oil cups 62 are separated.

[0168] When the adapter assembly 63 is at its second limit length, depending on whether the adapter assembly 63 allows one or two adjacent sub-oil cups 62 to rotate, the structure of the adapter assembly 63 can be divided into the following two embodiments:

[0169] Example 1

[0170] In this first embodiment, when the adapter 63 is at its second limit length, the adapter 63 allows two adjacent sub-oil cups 62 to rotate.

[0171] In this first embodiment, the adapter 63 includes an adapter shell 631 and a fixing component 632. One end of the adapter shell 631 is connected to a sub-oil cup 62 through a fixing component 632, and the other end of the adapter shell 631 is connected to another sub-oil cup 62 through another fixing component 632. One end of the fixing component 632 is connected to the sub-oil cup 62, and the other end is slidably connected to the adapter shell 631 along the arrangement direction of the multiple sub-oil cups 62.

[0172] In use, when the adapter assembly 63 is adjusted to its first limit length (shortest length), the two fixing components 632 slide into the adapter housing 631 and engage with it, thus limiting the position of the two fixing components 632 relative to the adapter housing 631. When the adapter assembly 63 is adjusted to its second limit length (longest length), the two fixing components 632 disengage from the adapter housing 631, slide out of the adapter housing 631, and rotatably connect with it. Figure 18 As shown, the user can adjust the angle of the two fixed components 632 relative to the adapter shell 631.

[0173] The aforementioned adapter component 63 has a simple structure. When adjusting the length of the adapter component 63, the user only needs to overcome the clamping force between the fixing component 632 and the adapter shell 631. The operation is convenient and simple, and no auxiliary tools are required.

[0174] In this first embodiment, as Figure 19 As shown, optionally, the adapter shell 631 has a sliding cavity 6311 and an adapter cavity 6312. Both ends of the sliding cavity 6311 are connected to the adapter cavity 6312. The adapter shell 631 has two first slots 6313 that are connected to the sliding cavity 6311 and are respectively used to engage with two fixing components 632.

[0175] When the adapter assembly 63 is at its first limit length, the ends of the two fixing components 632 extending into the adapter housing 631 are located in the sliding cavity 6311 and are respectively engaged with the two first slots 6313. During the process of adjusting the adapter assembly 63 from the first limit length to the second limit length, the two fixing components 632 slide relative to the sliding cavity 6311, so that the ends of the two fixing components 632 connected to the sub-oil cup 62 gradually extend out of the adapter housing 631. When the adapter assembly 63 is at its second limit length, the ends of the two fixing components 632 extending into the adapter housing 631 are respectively located in the two adapter cavities 6312. The aforementioned ends can rotate within the adapter cavities 6312, thereby realizing the adjustment of the angle of the sub-oil cup 62.

[0176] In this first embodiment, as Figure 19 As shown, the adapter shell 631 includes a back plate 6314 and a first outer shell 6315 connected to the back plate 6314. A sliding cavity 6311 and an adapter cavity 6312 located at both ends of the sliding cavity 6311 are formed between the back plate 6314 and the first outer shell 6315.

[0177] The aforementioned adapter shell 631 has a simple structure and can guide the movement of the two fixed components 632, ensuring that the two sub-oil cups 62 are stably folded.

[0178] Specifically, the back plate 6314 can be positioned facing the ion oil cup 62, and the first outer shell 6315 can be connected to one side of the back plate 6314 facing the ion oil cup 62. The back plate 6314 and the first outer shell 6315 can be connected by welding, adhesive bonding, or other methods.

[0179] like Figure 19 As shown, a transition cavity 6312 is formed between the shell walls at both ends of the first outer shell 6315 and the first outer shell 6315. The shell walls at both ends of the first outer shell 6315 can be bent into an arc shape, which guides the rotation of the fixing component 632 and ensures the rotational stability of the fixing component 632.

[0180] like Figure 20 As shown, in the folded state, due to the presence of the adapter shell 631, the ends of the two sub-oil cups 62 connected by the adapter assembly 63 are set apart.

[0181] In this first embodiment, as Figure 19As shown, the fixing component 632 includes a fixing member 6321 and a snap-fit ​​member 6322; one end of the fixing member 6321 has a rotating shaft 6323 that is slidably connected to the adapter housing 631 along the arrangement direction of the plurality of sub-oil cups 62, and the other end can be connected to the sub-oil cups 62 by welding, screw connection or other connection methods; the snap-fit ​​member 6322 can be installed on the fixing member 6321 by welding, glue connection or other connection methods, and the snap-fit ​​member 6322 is used to snap into the first slot 6313 on the adapter housing 631.

[0182] The aforementioned fixing component 632 is provided with a snap-fit ​​member 6322, which may have an elastic structure such as a spring clip, thereby facilitating the snap-fit ​​member 6322 to engage with the first slot 6313 and to disengage the snap-fit ​​member 6322 from the first slot 6313. Furthermore, the end of the aforementioned fixing component 632 has a rotating shaft 6323, which can slide with the sliding cavity 6311 and rotate with the transition cavity 6312, ensuring the stability of the movement of the fixing component 632.

[0183] To ensure that the snap-fit ​​6322 is stably installed in the fixing member 6321, the fixing member 6321 may be recessed with an installation groove, and the snap-fit ​​6322 is installed in the installation groove.

[0184] Specifically, the end of the fastener 6321 used to connect with the sub-oil cup 62 can be plate-shaped to increase the connection area with the sub-oil cup 62.

[0185] Example 2

[0186] In this second embodiment, as Figure 21 As shown, when the adapter assembly 63 is at its second limit length, the adapter assembly 63 allows one adjacent sub-oil cup 62 to rotate.

[0187] In this second embodiment, as Figures 21 to 23 As shown, the adapter assembly 63 also includes an adapter shell 631 and a fixing assembly 632. The difference from the above embodiment 1 is that the adapter shell 631 is connected to one sub-oil cup 62 through a fixing assembly 632, and the adapter shell 631 is directly connected to another sub-oil cup 62.

[0188] In use, in Embodiment 1 above, the two sub-oil cups 62 can adjust their angles relative to the adapter shell 631 via their respective connecting fixing components 632. In Embodiment 2, however, only one sub-oil cup 62 can adjust its angle relative to the adapter shell 631 via its connecting fixing component 632. Both methods achieve the folding function.

[0189] In this second embodiment, the adapter shell 631 also has a sliding cavity 6311 and an adapter cavity 6312. The difference from the first embodiment is that the sliding cavity 6311 is only connected to the adapter cavity 6312 at one end, and the adapter shell 631 has only one second slot 6317 that communicates with the sliding cavity 6311 and is used to engage with the fixing component 632.

[0190] The adjustment process is similar to that of Embodiment 1 above, and will not be described in detail here to save space.

[0191] In this second embodiment, as Figure 24 As shown, since the adapter shell 631 is directly connected to the sub-oil cup 62, in order to avoid the adapter shell 631 interfering with the fixing component 632 when the two adjacent sub-oil cups 62 are folded, thus preventing the two sub-oil cups 62 from being completely folded... Figure 25 In this state, the adapter cavity 6312 inside the adapter housing 631 protrudes in a direction away from the sub-oil cup 62 relative to the sliding cavity 6311, so that when the two sub-oil cups 62 are fully folded, the adapter cavity 6312 can accommodate the end of the fixing component 632 that extends into it.

[0192] like Figure 25 As shown, in the folded state, since the adapter shell 631 is directly connected to the sub-oil cup 62, the ends of the two sub-oil cups 62 connected by the adapter assembly 63 are staggered.

[0193] In this second embodiment, as Figure 23 and Figure 24 As shown, the adapter shell 631 includes a second outer shell 6316, which can be connected to the sub-oil cup 62 by welding, glue connection or other connection methods. The sliding cavity 6311 and the adapter cavity 6312 are located between the second outer shell 6316 and the sub-oil cup 62.

[0194] The aforementioned adapter shell 631 has a simple structure and can guide the movement of the fixing component 632, ensuring that the sub-oil cup 62 is stably folded.

[0195] The shell wall at one end of the second outer shell 6316 forms a transition cavity 6312 with the sub-oil cup 62. The shell wall at the end of the second outer shell 6316 can be bent into an arc shape, which guides the rotation of the fixing component 632 and ensures the rotational stability of the fixing component 632.

[0196] In this second embodiment, the structure of the fixing component 632 is the same as that of the fixing component 632 in the first embodiment above, and will not be described in detail here to save space.

[0197] In some embodiments, such as Figure 26 As shown, the main body 1 of the range hood is provided with a limiting structure 11, which is used to limit the angle at which the flip shell 2 flips into the opening 121.

[0198] The limiting structure 11 can limit the flipping housing 2, so that when the range hood is turned off, the flipping housing 2 will not flip excessively upward due to the first drive mechanism 4 or other malfunctions, which would damage the fan 13 and the product as a whole, resulting in greater property damage and safety risks.

[0199] Specifically, such as Figure 27 As shown, the surface of the limiting structure 11 facing the flip shell 2 may have a second arc surface 1131 and a limiting surface 1132 connected to the top of the second arc surface 1131; the shape of the second arc surface 1131 is adapted to the first arc surface 2111 to ensure that the flip shell 2 flips more smoothly and avoids jamming during the flipping process; the limiting surface 1132 may abut against the top of the flip shell 2 to limit the angle at which the flip shell 2 flips into the opening 121.

[0200] It should be noted that the limiting surface 1132 needs to form a certain angle with the first arc surface 2111 to prevent the flipping shell 2 from continuing to flip upward.

[0201] like Figure 27 As shown, the limiting structure 11 may include a top limiting wall 111, a front limiting wall 112, a bottom limiting wall 113 and a rear limiting wall 114 connected in sequence. The top limiting wall 111 can be connected to the flip housing 2 by screws. The bottom limiting wall 113 has a second arc surface 1131 and a limiting surface 1132 on the surface facing the flip housing 2.

[0202] In some embodiments, such as Figure 28 As shown, the main body 1 of the smoke hood includes a main housing 12 and a fan 13 installed in the main housing 12; the flip-top housing 2 is rotatably engaged with the main housing 12 and forms a flue between the main housing 12 and the main housing 12. The flip-top housing 2 is arranged opposite to the fan 13, and the surface of the flip-top housing 2 facing the fan 13 is provided with a clearance opening 2113 to avoid the fan 13.

[0203] The clearance opening 2113 can avoid some of the internal structure of the range hood body 1 when the flip shell 2 is in the stopped state. When the flip shell 2 flips into the range hood body 1, it will not collide with the internal structure of the range hood body 1, thus making the internal structure of the range hood body 1 more compact.

[0204] Specifically, the main body 1 of the range hood adopts a rear air intake duct (the smoke inlet of the fan 13 is set to face the rear towards the mounting wall), which makes the smoke inlet of the fan 13 closer to the oil fume inlet, resulting in less attenuation of the smoke extraction effect and ensuring the smoke extraction effect.

[0205] Similar to the rotation method of the flip shell 2, the rotation of the flip shell 2 can be achieved manually by the user or automatically.

[0206] In some embodiments, to facilitate user operation, a second driving mechanism 5 is provided between the flip-up housing 2 and the smoke collection plate 3 for driving the smoke collection plate 3 to rotate relative to the flip-up housing 2.

[0207] In some embodiments, such as Figure 29 As shown, the second drive mechanism 5 includes a second power source 51 and a connecting rod assembly 52. ​​The second power source 51 is installed inside the flip-up housing 2. One end of the connecting rod assembly 52 is connected to the power output end of the second power source 51, and the other end extends out of the flip-up housing 2 and is rotatably connected to the smoke collection plate 3.

[0208] In use, the second power source 51 drives the connecting rod assembly 52 to rotate, and the connecting rod assembly 52 opens or closes the smoke collecting plate 3 through its own transmission.

[0209] The linkage assembly 52 may include a first linkage 521 and a second linkage 522, such as... Figure 32 As shown, one end of the first connecting rod 521 is fixedly connected to the power output end of the second power source 51, and the other end of the first connecting rod 521 passes through the through hole on the flip housing 2 and is hinged to the second connecting rod 522. The end of the second connecting rod 522 away from the first connecting rod 521 is hinged to the smoke collection plate 3.

[0210] When using, such as Figure 29 As shown, the smoke collector 3 is currently in the open state; when it is necessary to close the smoke collector 3, as shown... Figure 30 As shown, the first connecting rod 521 can be rotated clockwise by the power output end of the second power source 51, while the second connecting rod 522 rotates counterclockwise relative to the first connecting rod 521, thereby causing the smoke collecting plate 3 to rotate counterclockwise relative to the flipping housing 2; subsequently, as Figure 31 As shown, the power output end of the second power source 51 continues to drive the first connecting rod 521 to rotate clockwise until the smoke collection plate 3 is engaged with the bottom of the bottom wall 212 in the flip shell 2.

[0211] Among them, such as Figure 32 As shown, the second power source 51 may include a second damping motor, which is mounted on a mounting base by screws, and the mounting base is mounted inside the flip-up housing 2 by screws.

[0212] The second drive mechanism 5 described above has the following advantages:

[0213] First, the second drive mechanism 5 mentioned above is easy to install. As a modular design, subsequent maintenance and replacement only requires replacing a single part, saving replacement costs.

[0214] Secondly, the aforementioned second drive mechanism 5 can achieve stepless steering by precisely rotating the damping motor and accurately calculating and coordinating the angle and length of the linkage mechanism, making the opening and closing angles of the smoke-collecting plate 3 more precise and smooth.

[0215] Finally, the damping motor can be easily adjusted to change the opening and closing speed of the smoke collection plate 3, thereby achieving the best user experience.

[0216] Furthermore, since in some embodiments, both the flipping housing 2 and the smoke-collecting plate 3 adopt a precisely adjustable rotation mechanism (motor gear set and motor linkage set), it is simpler to perform linkage control of the two components (ensuring that the smoke-collecting plate 3 is fully open when the flipping housing 2 is fully open) and the linkage flipping is more precise.

[0217] In some embodiments, such as Figure 33 As shown, the smoke collection plate 3 includes a plate body 31, an electronic control housing 32, and electronic control components. The plate body 31 is rotatably connected to the side wall assembly 211 of the flip housing 2. One side of the plate body 31 has a touch button (not shown in the figure), which allows the user to control the range hood to perform a series of actions. The other side of the plate body 31 is equipped with the electronic control housing 32. An installation cavity is formed between the electronic control housing 32 and the plate body 31, and an electronic control component connected to the touch button is installed in the installation cavity.

[0218] Specifically, such as Figure 33 As shown, a mounting base may be provided on the electrical control housing 32, and the end of the second link 522 facing away from the first link 521 may be hinged to the mounting base.

[0219] In some embodiments, such as Figure 34 As shown, the main body 1 of the smoke hood is equipped with a smoke sensor 7 or a hand gesture sensor 8. The first drive mechanism 4 and the second drive mechanism 5 are electrically connected to the smoke sensor 7 through electronic control components, and the first drive mechanism 4 and the second drive mechanism 5 are electrically connected to the hand gesture sensor 8 through electronic control components.

[0220] When the wok and steamer are in use, they generate fumes or steam. The fume sensor 7 detects the fumes inside the wok, turns on the range hood, and flips the casing 2 to the operating position. At the same time, the smoke collection plate 3 flips and fully opens. After opening, it can be operated via the touch buttons on the smoke collection plate 3.

[0221] Alternatively, when using a wok or steamer, the range hood can be turned on via the gesture sensor 8.

[0222] In at least one embodiment, the range hood body 1 is equipped with a smoke sensor 7 and a gesture sensor 8. These two opening methods provide users with more control options, allowing them to choose between more autonomous manual operation or intelligent sensor-activated opening, resulting in a better user experience.

[0223] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
