Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a side-suction 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] To improve the fume extraction effect, some existing side-suction range hoods typically use a movable flap structure to open or close the air inlet. However, the drive components used to flip the flap structure are generally located inside the fume collection chamber, which are easily damaged by long-term contact with fumes, thus shortening the lifespan of the range hood.

[0004] Therefore, there is an urgent need to provide a side-suction range hood to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a side-suction range hood, which can isolate oil fumes and extend the service life of the first drive component by installing the first drive component in the protective cavity opened at the rear of the smoke collection cavity.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A side-suction range hood includes a housing and a flap. The housing contains a smoke collection chamber, and the flap is movably connected to the smoke collection chamber. The two are opened or closed relative to the housing by a drive mechanism. When opened, the smoke collection chamber moves out of the housing, and the flap flips relative to the smoke collection chamber. When fully closed, the flap is in a vertical position and fits against and covers the front side of the housing.

[0008] The driving mechanism includes a first driving component for driving the flap to move. The smoke collection chamber is provided with a protective cavity. The front side of the smoke collection chamber is provided with a through hole communicating with the protective cavity. The first driving component is installed in the protective cavity. The output end of the first driving component passes through the through hole and is connected to the back of the flap.

[0009] As an optional solution, the perforation is sealed with an elastic seal, the elastic seal has a slit, the output end of the first drive component passes through the slit and connects to the back of the flap, and the slit is sealed and wrapped around the outside of the output end of the first drive component.

[0010] As an optional solution, the cut includes multiple transverse cuts and one longitudinal cut. The longitudinal cut extends through the multiple transverse cuts along the length of the elastic seal to form multiple tightly fitting sealing teeth at the cut. The multiple sealing teeth can seal and wrap around the outside of the output end of the first drive assembly.

[0011] As an alternative, the orthographic projection of the perforation onto the elastic seal falls within the range of the elastic seal, and the elastic seal is fitted to the front side of the smoke collection chamber and completely covers the perforation;

[0012] Alternatively, the elastic seal may be interference-fitted with the perforation.

[0013] As an alternative, in the left-right direction, the protective cavity is located in the middle of the smoke collection cavity, and the output end of the first drive component is connected to the middle of the back of the flap.

[0014] As an alternative, the protective cavity divides the internal space of the smoke collection chamber into two separate smoke collection areas, left and right.

[0015] As an optional solution, the first drive assembly includes a first motor and a first swing arm assembly. The first motor is disposed inside the protective cavity, and one end of the first swing arm assembly is connected to the output shaft of the first motor, while the other end passes through the perforation and is movably connected to the back of the flip plate.

[0016] As an optional solution, the first swing arm assembly includes a first swing arm and a second swing arm. The first swing arm is located inside the protective cavity. One end of the first swing arm is connected to the output shaft of the first motor, and the other end is hinged to one end of the second swing arm. The other end of the second swing arm passes through the perforation and is hinged to the back of the flap.

[0017] As an optional solution, the first drive component further includes a mounting bracket, the mounting bracket comprising:

[0018] The first plate covers the upper opening of the protective cavity;

[0019] The second plate is connected to the first plate and located at the rear opening of the protective cavity. The second plate abuts against the rear side of the smoke collection cavity and is fastened thereto.

[0020] The third plate is connected to the second plate and extends into the protective cavity to be securely connected to the first motor.

[0021] As an alternative, the second plate covers part of the rear opening of the protective cavity, and the rear opening of the protective cavity not covered by the second plate forms a clearance opening. At least a part of the first motor is directly opposite the second plate, and the first swing arm assembly is directly opposite the clearance opening.

[0022] As an optional solution, the front end of the first plate is provided with a claw, which can be inserted into and abut against the bottom of the upper side wall of the smoke collection cavity;

[0023] And / or, a support edge is provided at the edge of the upper opening of the protective cavity, and the lower surface of the first plate abuts against the support edge.

[0024] The beneficial effects of this utility model are:

[0025] This utility model provides a side-suction range hood. In the working state, the first drive assembly drives the flap to flip open relative to the smoke collection chamber, while the smoke collection chamber moves out of the housing, achieving the same smoke extraction effect as a side-suction range hood. The flap also helps to collect smoke, effectively improving smoke collection efficiency and preventing smoke escape. In the non-working state, the smoke collection chamber is hidden inside the housing, and the first drive assembly drives the flap to close, covering the front side of the housing. This makes the range hood more compact when not in use, reducing space occupation. The side-suction range hood provided by this utility model, by installing the first drive assembly in a protective cavity opened at the rear of the smoke collection chamber, can isolate smoke, minimizing direct contact between smoke and the first drive assembly, extending the service life of the first drive assembly, and thus extending the service life of the side-suction range hood.

[0051] 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.

[0052] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0053] 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.

[0054] 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.

[0055] Range hoods are an indispensable appliance in the kitchen. In current technology, to improve the smoke extraction effect, some side-draft range hoods usually use a movable flap structure to open or close the air inlet. However, the drive components used to flip the flap structure are generally located inside the smoke collection chamber, which is easily damaged by long-term contact with oil fumes, thus shortening the lifespan of the range hood.

[0056] Therefore, such as Figure 1 and Figure 2 As shown, this embodiment provides a side-suction range hood, including a main housing 8 and a smoke collection mechanism. A fan mechanism is installed inside the main housing 8, and the bottom of the main housing 8 has an opening. The smoke collection mechanism is connected to the bottom of the main housing 8 and located at the opening, allowing the smoke collection mechanism to communicate with the fan mechanism through the opening. When the range hood is needed to perform smoke extraction, the fan mechanism is activated, and the smoke collection mechanism extracts the generated fumes, preventing fumes from escaping. A decorative cover 9 can be optionally installed on the outside of the main housing 8 for aesthetic purposes.

[0057] Specifically, such as Figures 1 to 3As shown, the smoke collection mechanism includes a housing 1 and a flap 3. The housing 1 contains a smoke collection cavity 2. The flap 3 is movably connected to the smoke collection cavity 2, and the two are opened or closed relative to the housing 1 by a drive mechanism. When opened, the smoke collection cavity 2 moves out of the housing 1, and the flap 3 flips relative to the smoke collection cavity 2. When fully closed, the flap 3 is in a vertical state and fits against and covers the front side of the housing 1. The drive mechanism includes a first drive assembly 6, which is used to drive the flap 3 to move. The smoke collection cavity 2 is provided with a protective cavity 251. The front side of the smoke collection cavity 2 is provided with a through hole 211 communicating with the protective cavity 251. The first drive assembly 6 is installed in the protective cavity 251, and the output end of the first drive assembly 6 passes through the through hole 211 and is connected to the back of the flap 3.

[0058] like Figure 1 As shown, in the working state, the first driving component 6 drives the flap 3 to flip open relative to the smoke collection chamber 2, and at the same time, the smoke collection chamber 2 can be moved out of the housing 1, achieving the same smoke extraction effect as a side-suction range hood. Furthermore, the flap 3 can also collect smoke, effectively improving smoke collection efficiency and helping to prevent oil fumes from escaping; Figure 2 As shown, in the non-working state, the smoke collection chamber 2 is hidden inside the housing 1, and the first drive assembly 6 drives the flap 3 to close. The flap 3 is in a vertical state covering the front side of the housing 1, making the structure of the range hood more compact when not in use and reducing the space occupied.

[0059] The side-suction range hood provided in this embodiment can isolate oil fumes by installing the first drive component 6 in the protective cavity 251 opened at the rear of the smoke collection cavity 2, thereby minimizing direct contact between oil fumes and the drive part of the first drive component 6, extending the service life of the first drive component 6, and thus extending the service life of the side-suction range hood.

[0060] The top of the flap 3 is rotatably connected to the top of the smoke collection chamber 2. This arrangement ensures that when the flap 3 is fully opened, its bottom end opens relative to the smoke collection chamber 2, thereby better absorbing the generated fumes. In this embodiment, the top of the flap 3 is rotatably connected to the smoke collection chamber 2 via a hinge 31. In another optional embodiment, the top of the flap 3 can also be rotatably connected to the smoke collection chamber 2 via a hinge or a pivot.

[0061] Specifically, such as Figure 4As 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.

[0062] Among them, combined Figure 3 and Figure 4 The first motor 61 is installed inside the protective cavity 251, and the first swing arm 621 is also located inside the protective cavity 251. The second swing arm 622 passes through the perforation 211 and connects to the back of the flap 3. By installing the first motor 61 inside the protective cavity 251 opened on the rear side of the smoke collection cavity 2, the oil fumes can be isolated, the direct contact between the oil fumes and the first motor 61 can be minimized, and the service life of the first motor 61 can be extended, thereby extending the service life of the side-suction range hood.

[0063] The first motor 61 can be a Hall motor, which can control the opening angle of the flip plate 3 according to cooking needs, such as three levels of adjustment: fully closed, half open, and fully open.

[0064] Specifically, such as Figure 4 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 through hole 211 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.

[0065] Furthermore, such as Figure 1 and Figure 5As 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 output end of the first drive assembly 6 passes through the slit and connects to the back of the flap 3. The slit is sealed and wrapped around the outside of the second swing arm 622 to prevent oil fumes from entering the protective cavity 251 through the perforation 211 and adhering to the first motor 61, which would increase its operating resistance, noise, or even damage.

[0066] Specifically, such as Figure 5 As shown, the cut includes multiple transverse cuts 2121 and one longitudinal cut 2122. The longitudinal cut 2122 extends along the length of the elastic seal 212 through the multiple transverse cuts 2121 to form multiple tightly fitting sealing teeth 2123 at the cut. The multiple sealing teeth 2123 can seal and wrap around the outside of the second swing arm 622. First, each sealing tooth 2123 can deform independently to adapt to the movement trajectory of the second swing arm 622, ensuring more uniform sealing contact. Second, the edges of the sealing teeth 2123 can scrape off oil adhering to the surface when the second swing arm 622 moves, preventing oil from entering the interior. Furthermore, this cut shape can distribute the load to multiple sealing teeth 2123, avoiding local stress concentration caused by long cuts and reducing the risk of tearing or deformation.

[0067] In an optional embodiment, the orthographic projection of the perforation 211 onto the elastic seal 212 falls within the area of ​​the elastic seal 212, and the elastic seal 212 is fitted snugly to the front side of the smoke collection chamber 2 and completely covers the perforation 211. This arrangement achieves a good seal between the elastic seal 212 and the perforation 211, preventing oil fumes from entering the protective cavity 251 through the gap between the perforation 211 and the elastic seal 212. Optionally, the elastic seal 212 can be installed on the front side of the smoke collection chamber 2 by adhesive, snap-fit, or screw connection, without specific limitation.

[0068] In another alternative embodiment, the resilient seal 212 may also be interference-fitted with the perforation 211. This also achieves a good seal between the resilient seal 212 and the perforation 211, preventing oil fumes from entering the protective cavity 251 through the gap between the perforation 211 and the resilient seal 212.

[0069] Furthermore, such as Figure 3 As shown, in the left-right direction, the protective cavity 251 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.

[0070] like Figure 1As shown, 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.

[0071] 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.

[0072] 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.

[0073] It should be noted that, optionally, the main body 21 of the smoke collection chamber is formed by riveting together a first plate located on the front side and a second plate located on the rear side, which facilitates the processing of individual components. The oil mesh 22 is installed on the front side of the first plate, and a ventilation opening is provided on the rear side of the second plate to facilitate the flow of oil fumes into the main box 8. Figure 6 As shown, the smoke collection chamber 2 also includes a partition 25, which has a U-shaped structure. A through hole is provided in the middle of the second plate. The partition 25 is installed at the through hole, and the internal space of the partition 25 forms the aforementioned protective cavity 251.

[0074] Furthermore, such as Figure 6 As shown, the protective cavity 251 divides the internal space of the smoke collection chamber 2 into two separate smoke collection areas, left and right. An oil filter 22 is installed on the front side of each smoke collection area. In this way, each smoke collection area can correspond to one stove, achieving precise smoke extraction and improving smoke extraction efficiency.

[0075] Furthermore, combined Figure 3 and Figure 7As shown, the first drive assembly 6 also includes a mounting bracket 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 251. 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 251. 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 251 and is fastened to the first motor 61.

[0076] First, the mounting bracket 63 is used to fix the first motor 61 and covers the opening of the protective cavity 251 to isolate the oil fumes. Second, since the flap 3 is heavy, if the mounting bracket 63 is not strong enough, the mounting bracket 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 bracket 63 against the rear side of the smoke collection cavity 2, its structural strength can be guaranteed.

[0077] Specifically, such as Figure 7 As shown, the second plate 632 covers part of the rear opening of the protective cavity 251, and the rear opening of the protective cavity 251 not covered by the second plate 632 forms a clearance opening 252. At least part of the first motor 61 is directly opposite the second plate 632 to play a protective role, and the first swing arm assembly 62 is directly opposite the clearance opening 252.

[0078] 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 252 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 252. 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 bracket 63 can be removed to repair or replace the first motor 61, making machine maintenance convenient.

[0079] Optionally, such as Figure 7 As shown, the front end of the first plate 631 is provided with a claw 6311, which can be inserted into and abut against the bottom of the upper side wall of the smoke collection chamber 2. Since the front side of the first plate 631 is an external component after the smoke collection chamber 2 is fully opened, and maintenance needs to be considered, it is inconvenient and unsightly to screw in screws here. Therefore, the claw 6311 is used to prevent the first plate 631 from lifting up, while also taking into account both aesthetics and ease of maintenance.

[0080] Optionally, such as Figure 8As shown, a support edge 26 is provided at the edge of the upper opening of the protective cavity 251, and the lower surface of the first plate 631 abuts against the support edge 26. The support edge 26 can provide positioning and support for the first plate 631 when the mounting bracket 63 is installed, ensuring the stability of the connection of the first plate 631.

[0081] Furthermore, such as Figure 9 As shown, in this embodiment, the driving mechanism further includes a second driving component 7, which is used to drive the smoke collection chamber 2 to open or close relative to the housing 1.

[0082] By driving the flap 3 and the smoke collection chamber 2 separately with the first drive component 6 and the second drive component 7 respectively, the stability of the movement of the flap 3 and the smoke collection chamber 2 can be guaranteed. At the same time, compared with the solution of using a single drive mechanism to drive the flap 3 and the smoke collection chamber 2 at the same time, it can avoid the drive mechanism structure being too complicated and occupying more internal space in the longitudinal direction, which is conducive to reducing the longitudinal size of the range hood and saving kitchen space.

[0083] 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.

[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] Specifically, 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] In other words, 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] like Figure 1 As shown, when the smoke collection chamber 2 is fully open, the first smoke inlet 221 is tilted downwards. This allows the first smoke inlet 221 to face the stove and provides a larger smoke collection area, effectively improving smoke collection efficiency and helping to prevent oil fumes from escaping. When the flap 3 is fully closed, it covers the first smoke inlet 221, resulting in a neat and aesthetically pleasing appearance.

[0090] like Figure 10 As shown, when the smoke collection chamber 2 is fully open, the angle between the front side of the smoke collection chamber 2 and the vertical direction can be selected from 20° to 40°. Specifically, the angle can be 20°, 25°, 30°, 35°, or 40°. In this embodiment, the angle is preferably 30°, at which point the smoke collection effect is relatively better.

[0091] Furthermore, when the flap 3 and the smoke collection chamber 2 are fully open, an angle is formed between the flap 3 and the smoke collection chamber 2, creating a smoke-gathering area. The angle ranges from 0° to 180°. Optionally, the angle ranges from 55° to 95°. Specifically, the angle can be 55°, 60°, 65°, 70°, 75°, 80°, 85°, 90°, or 95°. Figure 4 As shown, in this embodiment, the included angle is preferably 77°, at which point the maximum depth of the smoke-collecting area is approximately 397 mm, resulting in a relatively large smoke-collecting area.

[0092] Optionally, during operation, the smoke collection chamber 2 can be selectively opened according to the needs of the cooking process. For example, during stewing, only the flap 3 can be opened, and the smoke collection chamber 2 can be left open; during stir-frying, both the smoke collection chamber 2 and the flap 3 can be fully opened.

[0093] Optionally, during operation, the smoke collection chamber 2 can always be fully open, and the opening state of the flap 3 can be selected according to the needs of the cooking state. For example, the flap 3 can be opened halfway during stewing, and fully opened during stir-frying.

[0094] Specifically, such as Figure 9 As shown, in this embodiment, the second driving component 7 includes a flipping component 71 and a guiding component 720. The flipping component 71 is used to drive the smoke collection chamber 2 to flip, and the smoke collection chamber 2 slides with the housing 1 through the guiding component 720.

[0095] In the working state, 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 guide component 720. The guide component 720 limits the sliding trajectory of the smoke collection chamber 2, ensuring that the smoke collection chamber 2 is stable and does not wobble during the sliding process. Through the guidance of the guide component 720, the smoke collection chamber 2 can flip outward relative to the housing 1 when it is open, and at the same time generate an outward sliding displacement in the tilt direction. Therefore, the smoke collection area extends forward, thereby expanding the coverage of the smoke collection area, effectively improving the smoke collection efficiency, helping to prevent the escape of oil fumes, and improving the air quality in the kitchen. In the non-working state, the flipping component 71 drives the smoke collection chamber 2 to move to the closed position, and the smoke collection chamber 2 is hidden inside the housing 1, making the structure of the range hood more compact and small when not in use, reducing the space occupied by the range hood.

[0096] Specifically, such as Figure 4 and Figure 11 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.

[0097] 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.

[0098] Specifically, such as Figure 11 and Figure 15 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.

[0099] When the output shaft of the second motor 711 rotates, it drives the transmission shaft 713 to rotate. The transmission shaft 713 drives the third swing arm 7121 to rotate. The third swing arm 7121 transmits power 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 are folded, 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.

[0100] Optionally, such as Figure 9 and Figure 11 As shown, the housing 1 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.

[0101] Furthermore, such as Figure 12 As shown, the guide component 720 includes a fixed guide 7201 and a sliding guide 7202. The fixed guide 7201 is connected to the housing 1 and extends along a preset direction. The sliding guide 7202 is connected to the smoke collection chamber 2 and slides in cooperation with the fixed guide 7201. The sliding guide 7202 rotates relative to the smoke collection chamber 2. Through the sliding cooperation of the fixed guide 7201 and the sliding guide 7202, the smoke collection chamber 2 can slide along a preset trajectory, ensuring smooth and stable movement without shaking during the sliding process.

[0102] Optionally, guide components 720 are provided on both the left and right sides of the smoke collection chamber 2 to ensure that the smoke collection chamber 2 slides smoothly without shaking. Further, two sets of guide components 720 are provided on each of the left and right sides of the smoke collection chamber 2, and the sliding guide 7202 in the two sets of guide components 720 is set at an angle to each other, further ensuring that the smoke collection chamber 2 slides smoothly without shaking.

[0103] Specifically, such as Figure 12As shown, in this embodiment, the two sets of guide components 720 on either side are the first guide component 72 and the second guide component 73, respectively. The first guide component 72 is located below the second guide component 73. The first guide component 72 includes a fixed guide component 7201 and a sliding guide component 7202. The fixed guide component 7201 is a guide bracket 721, which is fixed to the outer side of the inner side plate 13. The sliding guide component 7202 is a guide shaft 722. A guide hole 7211 is provided on the guide bracket 721. 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 also includes a fixed guide component 7201 and a sliding guide component 7202. The fixed guide component 7201 is a guide rail 732, which is fixed to the inner side of the inner side plate 13. The sliding guide component 7202 is a slider 731, which can slide along the guide rail 732. The end of the slider 731 is rotatably connected to the smoke collection chamber 2.

[0104] In another optional embodiment, both sets of guide components 720 on either side may be configured with guide brackets 721 and guide shafts 722, or they may be configured with guide rails 732 and sliders 731. No specific limitation is made here.

[0105] In this embodiment, 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 within 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 moves smoothly without shaking during the sliding process.

[0106] The angle between the extension direction of the guide hole 7211 and the vertical direction can be selected from 10° to 22°, specifically, the angle can be 10°, 12°, 14°, 16°, 18°, 20° or 22°. The angle between the extension direction of the guide rail 732 and the horizontal front-back direction can be selected from 11° to 23°, specifically, the angle can be 11°, 13°, 15°, 17°, 19°, 21° or 23°.

[0107] In this embodiment, the angle between the extending direction of the guide hole 7211 and the vertical direction is preferably 15.9°, and the angle between the extending direction of the guide rail 732 and the horizontal front-back direction is preferably 17°. At this time, the trajectory of the smoke collection chamber 2 changes as follows: Figure 13As shown, the solid line represents the state when the smoke collection chamber 2 is completely closed, and the dashed line represents the state when the smoke collection chamber 2 is completely open. When the smoke collection chamber 2 is completely open, the angle between its front side and the vertical direction can reach 30°, resulting in a relatively good smoke collection effect.

[0108] In other optional embodiments, when the angle between the extension direction of the guide hole 7211 and the vertical direction, and the angle between the extension direction of the guide rail 732 and the front and rear horizontal direction are selected to be other angles, the angle between the front side of the smoke collection cavity 2 and the vertical direction can be adaptively varied within the range of 20° to 40°.

[0109] Furthermore, such as Figure 14 As shown, chamfers 7212 are provided on both sides of the hole wall of the guide hole 7211. This design reduces the contact area between the hole wall of the guide hole 7211 and the guide shaft 722. When the guide shaft 722 moves in the guide hole 7211, it avoids the guide shaft 722 being subjected to radial force and twisting during its movement, thus preventing excessive friction with the guide hole 7211 and hindering its movement. This effectively ensures the movement of the guide shaft 722.

[0110] Optionally, combined Figure 11 and Figure 14 The inner side plate 13 of the housing 1 has a through hole directly opposite the guide hole 7211. A rib 7213 is provided on one side of the guide bracket 721. The rib 7213 is arranged around the periphery of the guide hole 7211 and can pass through the through hole. By passing the rib 7213 through the through hole, the installation position of the guide bracket 721 can be positioned, which facilitates the installation of the bracket on the inner side plate 13.

[0111] In this embodiment, the guide components 720 on both the left and right sides of the smoke collection chamber 2 are identical, both employing the cooperation of a slider 731 and a guide rail 732, as well as the cooperation of a guide bracket 721 and a guide shaft 722. For example... Figure 9 As shown, one end of the drive shaft 713 is connected to the output shaft of the second motor 711, and the other end of the drive shaft 713 is rotatably connected to the guide bracket 721 on the side away from the second motor 711. In this way, the rotation center support at the left end of the drive shaft 713 and the guide bracket 721 are designed as a single unit, thereby ensuring the accuracy of their relative positions and making the motion trajectory more stable.

[0112] Furthermore, such as Figure 11As shown, a limiting member 131 is provided on the inner side plate 13 of the housing 1 for mounting the second motor 711. The limiting member 131 includes two limiting protrusions 1311, both of which are located on the rotation path of the third swing arm 7121. When the smoke collection chamber 2 is fully open, the third swing arm 7121 can abut against one of the limiting protrusions 1311. When the smoke collection chamber 2 is fully closed, the third swing arm 7121 can abut against the other limiting protrusion 1311. Since the movement of the smoke collection chamber 2 is restricted by the second swing arm assembly 712, the slider 731 and the guide rail 732, the guide shaft 722 and the guide hole 7211, if all three are set with corresponding limits according to the end point and the start point of the smoke collection chamber 2, it will lead to the problem that the smoke collection chamber 2 cannot be fully closed or fully opened. Therefore, this application reserves a margin for the starting and ending points of the travel of the guide rail 732 and the guide hole 7211. By setting the limiting member 131, only the two extreme positions of the third swing arm 7121 are restricted, thereby ensuring the accuracy of the closing and opening of the smoke collection chamber 2.

[0113] Furthermore, such as Figure 6 , Figure 12 and Figure 15 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.

[0114] Specifically, such as Figure 15 As shown, the cavity reinforcement 23 includes a first wall plate 231, a second wall plate 232, and a third wall plate 233. The first wall plate 231 is flush with the front side of the smoke collection cavity 2. The second wall plate 232 is perpendicularly connected to the first wall plate 231 and is attached to the left and right sides of the smoke collection cavity body 21. The third wall plate 233 is perpendicularly connected to the first wall plate 231 and is parallel and spaced apart on the side of the second wall plate 232 away from the smoke collection cavity body 21. The fourth swing arm 7122 and the swing arm bracket 7123 are located between the second wall plate 232 and the third wall plate 233, and the swing arm bracket 7123 is connected to both the second wall plate 232 and the third wall plate 233. The guide rail 732 is hinged to the side of the third wall plate 233 away from the second wall plate 232. 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 third wall plate 233 to meet the motion trajectory requirements.

[0115] During installation, the fourth swing arm 7122 is first riveted to the swing arm bracket 7123. Then, the two free ends of the swing arm bracket 7123 are respectively locked to the second wall plate 232 and the third wall plate 233 of the cavity reinforcement 23 by screws. After that, a press-fit nut is riveted to the third wall plate 233 of the cavity reinforcement 23. One end of the slider 731 is fitted onto the column of the press-fit nut and then fixed with screws. This makes the hinge axis of the swing arm bracket 7123 and the fourth swing arm 7122 coaxial with the hinge axis of the slider 731 and the third wall plate 233, which is easier for workers to assemble and improves assembly efficiency.

[0116] It should be noted that, as Figure 15 As shown, the top end of the first wall plate 231 of the cavity reinforcement 23 extends laterally and is stacked on the rear side of the top end of the smoke collection cavity body 21. One end of the hinge 31 is riveted to the flip plate 3 by a semi-hollow rivet, and the other end is fixed to the top end of the smoke collection cavity body 21 and the first wall plate 231 by a press-fit nut screw, which strengthens the structural strength of the top end of the smoke collection cavity body 21 and prevents deformation.

[0117] In this embodiment, as Figure 1 and Figure 6 As shown, inner glass 5 is installed at both ends of the front side of the smoke collection chamber 2. Each inner glass 5 extends outward in the left and right directions, but does not exceed the left and right sides of the flap 3. The inner glass 5 on both sides not only improves the aesthetics, but also increases the smoke collection area and reduces the escape of oil fumes.

[0118] Furthermore, such as Figure 6 As shown, the smoke collection chamber 2 also includes inner glass supports 24 located at the left and right ends. The inner glass supports 24 have an L-shaped structure, including a first part and a second part connected vertically. The first part of the inner glass supports 24 is stacked and connected to the outside of the first wall plate 231 of the chamber reinforcement 23. The first part can be fixed to the chamber reinforcement 23 by means of buckles, screws or glue. The inner glass 5 is connected to the first part and fixed by glue. The second part of the inner glass supports 24 covers the outside of the chamber reinforcement 23 in the left and right direction, which can cover the slider 731, the swing arm support 7123 and the fourth swing arm 7122 connected to the chamber reinforcement 23, and play an aesthetic role.

[0119] In this embodiment, as Figure 11As shown, a pad 733 is fixed to the side of the inner side plate 13 near the smoke collection chamber 2, and a guide rail 732 is fixed to the pad 733. The function of the pad 733 is to raise the guide rail 732, so that there is a certain gap between the guide rail 732 and the inner side plate 13, so that the second part of the inner glass support 24 avoids the guide rail 732 after the smoke collection chamber 2 is completely closed. After the smoke collection chamber 2 is completely closed, the second part of the inner glass support 24 is accommodated in the gap between the guide rail 732 and the inner side plate 13.

[0120] In this embodiment, as Figure 17 As shown, the housing 1 resembles a cuboid structure, with its front side forming a vertical plane. When fully closed, the flap 3 is vertical, fitting snugly and completely covering the front side of the housing 1. This design makes the side-suction range hood more compact when not in use, achieving a thinner body size, reducing space occupation, facilitating embedded installation, and from the front, the flap 3 appears as a complete flat structure without gaps, making it easy to clean. It also enhances the overall aesthetics, clearly distinguishing it from traditional or other range hood structures in the industry.

[0121] In this embodiment, as Figure 16 As shown, the flap 3 is a flat plate structure extending vertically and is made of glass. When the smoke collection chamber 2 and the flap 3 are fully closed, the flap 3 remains parallel to the wall and completely covers the smoke collection chamber 2, presenting a flat appearance and visually achieving a thinner body size. In this embodiment, with the smoke collection chamber 2 and the flap 3 fully closed, the smoke collection mechanism has a thickness of approximately 142mm and a height of approximately 230mm, resulting in a small size that combines a compact body with a large smoke collection area. This achieves a large smoke collection area (e.g., 397mm) while maintaining a relatively small smoke collection mechanism size (e.g., 142mm wide, 230mm high).

[0122] It should be noted that this range hood can be installed either non-recessed, directly against the wall, or recessed, where the main unit (8) is embedded in the cabinet, with the smoke collection mechanism exposed at the bottom. The overall dimensions are designed to fully accommodate the actual size requirements of home cabinets. For example, refer to... Figure 16 The typical depth of a kitchen cabinet is 350mm, and the thickness of the cabinet door panel is approximately 20mm, leaving a remaining usable installation depth of about 330mm. Therefore, the front-to-back dimensions of the main cabinet 8 or decorative cover 9 are designed to be approximately 325mm, achieving a neat and aesthetically pleasing appearance while meeting installation requirements.

[0123] In this embodiment, as Figure 12As shown, the housing 1 also includes a top plate 15 on the upper side, a bottom plate 14 on the lower side, and a rear plate 17 on the rear side. The top plate 15 and the bottom plate 14 are arranged vertically at intervals. Two outer plates 12 are respectively connected to the left and right sides of the top plate 15 and the bottom plate 14. The rear plate 17 is connected to the rear side of the top plate 15, the bottom plate 14, and the outer plates 12, thereby forming a housing 1 with a rectangular structure.

[0124] like Figure 17 As shown, the side-suction range hood also includes an oil cup 4, which is detachably connected to the bottom of the base plate 14 of the housing 1. The vertical projection of the bottom edge of the smoke collection chamber 2 is 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. When the flap 3 is fully closed, it can cover the front side of the oil cup 4, so that the oil cup 4 is hidden inside the flap 3 and is not easily seen, which not only improves the overall aesthetics, but also facilitates the daily cleaning of the flap 3.

[0125] Optionally, the oil cup 4 is installed at the bottom of the base plate 14 by pulling it out from the front and back, which allows for easy disassembly and cleaning of the oil cup 4. The pulling-out method of the oil cup 4 is existing technology and will not be described in detail here.

[0126] In an optional embodiment, such as Figure 2 As shown, each outer panel 12 includes a sloping plate 121 and a straight plate 122. The two sloping plates 121 on the left and right sides gradually tilt in opposite directions from back to front. The straight plate 122 is connected to the front side of the sloping plate 121 and is set at an angle to the sloping plate 121. The straight plate 122 extends in the front-back direction. That is to say, the distance between the two outer panels 12 gradually narrows from front to back, making the size of the shell 1 appear smaller and reducing the space occupied.

[0127] In another alternative embodiment, the outer side plate 12 may also be a flat plate structure extending in the vertical direction, and the shell 1 may be a regular cuboid structure, which is convenient for manufacturing.

[0128] In this embodiment, as Figure 17 As shown, the bottom of the outer side plate 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 improves the overall aesthetics.

[0129] Combination Figure 1 and Figure 18An ambient light assembly 16 is provided on the outer side panel 12. The ambient light assembly 16 includes an ambient light body 162 and an ambient light bracket 161. The upper and lower ends of the ambient light bracket 161 are fixed to the housing 1. The ambient light body 162 is embedded in the ambient light bracket 161 and protrudes from the outer side panel 12. The ambient light body 162 mainly serves the functions of lighting and decoration, enhancing aesthetics. The ambient light bracket 161 is universal, and users can replace the ambient light body 162 according to their own lighting needs (such as color, brightness, or style).

[0130] like Figure 9 As shown, a sealing strip 27 is provided on the top of the smoke collection chamber 2. When the smoke collection chamber 2 is fully opened, the sealing strip 27 abuts against the top plate 15 of the housing 1 to seal the gap between the top of the smoke collection chamber 2 and the inner top of the top plate 15. This arrangement can effectively prevent oil fumes from overflowing from the gap between the top of the smoke collection chamber 2 and the top plate 15.

[0131] Furthermore, such as Figure 9 As shown, the top of the flap 3 is provided with a flange 32. When the flap 3 is fully opened, there is a gap between the top of the flap 3 and the top of the smoke collection chamber 2, and the flange 32 covers the upper side of the gap. This arrangement can effectively prevent oil fumes from overflowing from the gap between the top of the flap 3 and the top of the smoke collection chamber 2.

[0132] Specifically, the flange 32 is located on the rear side of the flap 3. When the flap 3 is fully closed, the flap 3 completely covers the flange 32, which not only prevents oil fumes from escaping but also ensures aesthetics.

[0133] like Figure 12 As shown, a limiting part 151 is provided on the inner side of the top plate 15. The limiting part 151 is designed as a cylindrical structure and can abut against the rear end of the upper side wall of the smoke collecting cavity 2 when the smoke collecting cavity 2 is fully opened. Because the smoke collecting cavity 2 is too heavy, the limiting part 151 can abut against the rear end of the upper side wall of the smoke collecting cavity 2 when the smoke collecting cavity 2 is fully opened, preventing the smoke collecting cavity 2 from sagging after opening. Optionally, the number of limiting parts 151 can be set to one, two or more in the left-right direction, and no specific limitation is made here.

[0134] Furthermore, such as Figure 1 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. This further increases the air intake area and improves the smoke intake efficiency.

[0135] 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.

[0136] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
