[0054] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0058] Range hoods are an indispensable and important household appliance in the kitchen. However, existing range hoods still have problems in balancing space utilization efficiency and smoke collection effect, especially side-suction range hoods. The smoke collection cavity is basically fixed, and the smoke collection area is limited, which affects the smoke collection effect. At the same time, the range hood occupies a relatively large kitchen space when not in use, which brings inconvenience to users, especially in small houses or apartments.

[0059] To this end, this embodiment provides a side-suction range hood, comprising a main box 8 (such as Figure 10The main housing 8 houses a fan mechanism (shown in the figure) and a smoke collection mechanism. The main housing 8 has an opening at the bottom, and 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 used for extraction, the fan mechanism activates and draws generated fumes through the smoke collection mechanism, preventing them from escaping. A decorative cover 9 can optionally be installed over the main housing 8 for aesthetic purposes.

[0060] Specifically, if Figure 1 and Figure 2 As shown, the smoke collecting mechanism includes a shell 1, which contains a smoke collecting cavity 2. The smoke collecting cavity 2 is connected to the shell 1 through a second driving component 7, and the second driving component 7 drives the smoke collecting cavity 2 to flip relative to the shell 1 while generating a sliding displacement in a horizontal or inclined direction. The second driving component 7 includes a flipping component 71 and a guide component 720. The flipping component 71 drives the smoke collecting cavity 2 to flip, and the smoke collecting cavity 2 slides with the shell 1 through the guide component 720.

[0061] In the working state, the flipping component 71 can drive the smoke collecting chamber 2 to flip, providing power to the smoke collecting chamber 2 to open or close, so that the smoke collecting chamber 2 extends outward from the shell 1 and reaches the smoking position. The smoke collecting chamber 2 slides with the shell 1 through the guide component 720. The guide component 720 limits the sliding trajectory of the smoke collecting chamber 2, ensuring that the smoke collecting chamber 2 is smooth and without shaking during the sliding process. Through the guidance of the guide component 720, the smoke collecting chamber 2 can be flipped outward relative to the shell 1 when opened, and at the same time produce an outward sliding displacement in an inclined direction, thereby extending the smoke collecting area, thereby expanding the coverage of the smoke collecting area, effectively improving the smoke collection efficiency, helping to prevent oil smoke from escaping, and improving the air quality in the kitchen; in the non-working state, the flipping component 71 drives the smoke collecting chamber 2 to move to the closed position, and the smoke collecting chamber 2 is hidden in the shell 1, making the structure more compact and compact when the range hood is not in use, reducing the space occupied by the range hood.

[0062] In this embodiment, the smoke collection chamber 2 is capable of sliding in an oblique direction relative to the housing 1. Specifically, when the smoke collection chamber 2 is open, it simultaneously tilts outward relative to the housing 1 and simultaneously slides upward. This expands the smoke collection area and elevates the chamber as a whole, preventing it from obstructing vision and bumping heads. Conversely, when the smoke collection chamber 2 is closed, it simultaneously tilts inward relative to the housing 1 and simultaneously slides downward, concealing it within the housing 1.

[0063] like Figure 1As shown, the front side of the smoke collection chamber 2 is provided with a first smoke inlet 221. When the smoke collection chamber 2 is fully opened, the first smoke inlet 221 is tilted downward. This allows the first smoke inlet 221 to face the stove and has a larger smoke collection area, effectively improving the smoke collection efficiency and helping to prevent oil smoke from escaping.

[0064] like Figure 3 As shown, when the smoke collection cavity 2 is fully open, the angle between the front side of the smoke collection cavity 2 and the vertical direction can be selected to be 20° to 40°. Specifically, the angle can be 20°, 25°, 30°, 35°, or 40°. In this embodiment, the angle is preferably 30°, at which the smoke collection effect is relatively good.

[0065] Specifically, if Figure 4 and Figure 16 As shown, the flip component 71 includes a second motor 711, a transmission shaft 713 and two sets of second swing arm groups 712. The second motor 711 is connected to the shell 1, and the transmission shaft 713 extends in the left and right directions. One end of the transmission shaft 713 is fixedly connected to the output shaft of the second motor 711, such as by welding or screwing, and the other end is passed through the shell 1. The two sets of second swing arm groups 712 are respectively connected to the left and right sides of the smoke collecting chamber 2 and are fixedly mounted on the transmission shaft 713 at the same time.

[0066] When the output shaft of the second motor 711 rotates, it drives the transmission shaft 713 to rotate, which in turn drives the two sets of second swing arm assemblies 712 to rotate synchronously. These two sets of second swing arm assemblies 712 then cause the smoke collection chamber 2 to flip relative to the housing 1 to open or close. In this way, the second motor 711, via the transmission shaft 713, drives the two sets of second swing arm assemblies 712 to rotate synchronously, allowing the left and right sides of the smoke collection chamber 2 to move synchronously when opening or closing, ensuring synchronization and stability of the movement.

[0067] Specifically, if Figure 4 and Figure 8 As shown, the second swing arm group 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 transmission shaft 713, such as by welding or screw fixation. The fourth swing arm 7122 is hinged to the third swing arm 7121, and the swing arm bracket 7123 is hinged to the fourth swing arm 7122 and fixedly connected to the smoke collecting chamber 2.

[0068] When the output shaft of the second motor 711 rotates, it drives the transmission shaft 713, which in turn drives the third swing arm 7121. The third swing arm 7121 transmits power through the fourth swing arm 7122 and the swing arm bracket 7123, ultimately driving the movement of the smoke collection chamber 2. By adopting this swing arm structure, when the smoke collection chamber 2 is closed, the third and fourth swing arms 7121, 7122 fold, occupying a small space. When the smoke collection chamber 2 is opened, the third and fourth swing arms 7121, 7122 extend, thereby opening the smoke collection chamber 2 to a specific angle to provide a larger smoke collection area.

[0069] Alternatively, as Figure 2 and Figure 4 As shown, the housing 1 includes inner panels 13 on the left and right sides and outer panels 12 on the left and right sides. The inner panels 13 are located inside the outer panels 12, and the outer panels 12 enclose a sealed chamber. The second motor 711 is located in one of the sealed chambers and fixed to the inner panels 13. By installing the second motor 711 in the sealed chamber, it can be isolated from oil smoke, minimize direct contact between the oil smoke and the second motor 711, and extend the service life of the second motor 711.

[0070] Furthermore, if Figure 5 As shown, the guide member 720 includes a fixed guide member 7201 and a sliding guide member 7202. The fixed guide member 7201 is connected to the housing 1 and extends along a predetermined direction. The sliding guide member 7202 is connected to the smoke collecting chamber 2. The sliding guide member 7202 slides with the fixed guide member 7201 and rotates relative to the smoke collecting chamber 2. The sliding cooperation between the fixed guide member 7201 and the sliding guide member 7202 enables the smoke collecting chamber 2 to slide along a predetermined trajectory, ensuring a smooth and rocking motion during the sliding process.

[0071] 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 is stable and does not shake during sliding. Furthermore, 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 directions of the sliding guides 7202 in the two sets of guide components 720 are arranged at an angle, further ensuring that the smoke collection chamber 2 is stable and does not shake during sliding.

[0072] Specifically, if Figure 5As shown, in this embodiment, the two groups of guide parts 720 on either side are respectively the first guide part 72 and the second guide part 73. The first guide part 72 is located at the lower side of the second guide part 73. The first guide part 72 includes a fixed guide part 7201 and a sliding guide part 7202. The fixed guide part 7201 is a guide bracket 721, which is fixed to the outer side of the inner plate 13. The sliding guide part 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 part 73 also includes a fixed guide part 7201 and a sliding guide 7202. The fixed guide part 7201 is a guide rail 732, which is fixed to the inner side of the inner plate 13. The sliding guide part 7202 is a slider 731. The slider 731 can slide along the guide rail 732, and the end of the slider 731 is rotatably connected to the smoke collecting chamber 2.

[0073] In another optional embodiment, the two sets of guide components 720 on either side may both adopt the setting of the guide bracket 721 and the guide shaft 722, or may both adopt the setting of the guide rail 732 and the slider 731, which is not specifically limited here.

[0074] In this embodiment, when the flipping component 71 drives the smoke collecting chamber 2 to flip, the smoke collecting chamber 2 drives the slider 731 and the guide shaft 722 to move, and the slider 731 rotates around the hinge point relative to the smoke collecting chamber 2 while sliding along the guide rail 732, and the guide shaft 722 rotates in the guide hole 7211 while sliding along the guide hole 7211. Through the coordinated action of the slider 731 and the guide shaft 722, the composite motion path of the entire smoke collecting chamber 2 is jointly determined, ensuring that the smoke collecting chamber 2 is smooth and without shaking during the sliding process.

[0075] The included angle between the extension direction of the guide hole 7211 and the vertical direction can be selected from 10° to 22°. Specifically, the included angle can be 10°, 12°, 14°, 16°, 18°, 20°, or 22°. The included angle between the extension direction of the guide rail 732 and the front-to-back horizontal direction can be selected from 11° to 23°. Specifically, the included angle can be 11°, 13°, 15°, 17°, 19°, 21°, or 23°.

[0076] In this embodiment, the angle between the extension direction of the guide hole 7211 and the up-down direction is preferably 15.9°, and the angle between the extension direction of the guide rail 732 and the front-back horizontal direction is preferably 17°. At this time, the trajectory of the smoke collecting cavity 2 changes as shown in FIG. Figure 6 As shown, the solid line represents the state when the smoke collecting cavity 2 is fully closed, and the dotted line represents the state when the smoke collecting cavity 2 is fully opened. After the smoke collecting cavity 2 is fully opened, the angle between its front side and the vertical direction can reach 30°, and the smoke collection effect is relatively good.

[0077] In other optional embodiments, when the angle between the extension direction of the guide hole 7211 and the up-down direction, and the angle between the extension direction of the guide rail 732 and the front-back horizontal direction are selected to be other angles, the angle between the front side surface of the smoke collecting chamber 2 and the vertical direction adaptively changes within the range of 20° to 40°.

[0078] Furthermore, if Figure 7 As shown, chamfers 7212 are provided on both side edges of the wall of the guide hole 7211. This arrangement can reduce the contact area between the wall of the guide hole 7211 and the guide shaft 722. When the guide shaft 722 moves in the guide hole 7211, it can prevent the guide shaft 722 from being twisted by radial forces during movement, thereby preventing excessive friction with the guide hole 7211 and causing movement obstruction, thereby effectively ensuring the movement of the guide shaft 722.

[0079] Optionally, combined Figure 4 and Figure 7 The inner 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 be inserted into the through hole. By inserting the rib 7213 into the through hole, the installation position of the guide bracket 721 can be positioned, facilitating the installation of the bracket on the inner plate 13.

[0080] In this embodiment, the guide components 720 on the left and right sides of the smoke collecting chamber 2 are the same, and both adopt the cooperation of the slider 731 and the guide rail 732 and the cooperation of the guide bracket 721 and the guide shaft 722. Figure 2 and Figure 4 As shown, one end of the transmission shaft 713 is connected to the output shaft of the second motor 711, and the other end of the transmission 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 member at the left end of the transmission shaft 713 and the guide bracket 721 are designed as a single piece, thereby ensuring the accuracy of the relative position of the two and making the motion trajectory more stable.

[0081] Furthermore, if Figure 4As shown, a limit member 131 is provided on the inner side plate 13 of the housing 1 for mounting the second motor 711. The limit member 131 includes two limit protrusions 1311. Both limit protrusions 1311 are located on the rotation path of the third swing arm 7121. When the smoke collecting chamber 2 is fully opened, the third swing arm 7121 can abut against one of the limit protrusions 1311. When the smoke collecting chamber 2 is fully closed, the third swing arm 7121 can abut against the other limit protrusion 1311. Since the movement of the smoke collecting chamber 2 is limited 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 starting point of the smoke collecting chamber 2, it will cause the smoke collecting chamber 2 to not be completely closed or opened. Therefore, the present application reserves margins for the starting and ending points of the travel of the guide rail 732 and the guide hole 7211, and by setting the limiter 131, only the two extreme positions of the third swing arm 7121 are limited, thereby ensuring the accuracy of closing and opening the smoke collecting chamber 2.

[0082] Furthermore, if Figure 9 As shown, the smoke collecting chamber 2 includes a smoke collecting chamber body 21 and a chamber reinforcement 23. The left and right ends of the smoke collecting 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. Figure 5 and Figure 8 As shown, the cavity reinforcement 23 strengthens the structural strength of the smoke collecting cavity body 21 to prevent deformation.

[0083] Specifically, if Figure 8 and Figure 9 As shown, the cavity reinforcement 23 includes a first wall panel 231, a second wall panel 232 and a third wall panel 233. The first wall panel 231 is flush with the front side of the smoke collecting chamber 2, the second wall panel 232 is vertically connected to the first wall panel 231 and is fitted with the left and right sides of the smoke collecting chamber body 21, the third wall panel 233 is vertically connected to the first wall panel 231 and is arranged in parallel and spaced apart on the side of the second wall panel 232 away from the smoke collecting chamber body 21, the fourth swing arm 7122 and the swing arm bracket 7123 are located between the second wall panel 232 and the third wall panel 233, and the swing arm bracket 7123 is connected to the second wall panel 232 and the third wall panel 233 at the same time, the guide rail 732 is hinged to the side of the third wall panel 233 away from the second wall panel 232, and 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 panel 233 to meet the motion trajectory requirements.

[0084] During installation, first rivet the fourth swing arm 7122 and the swing arm bracket 7123 together, and then use screws to lock the two free ends of the swing arm bracket 7123 to the second wall panel 232 and the third wall panel 233 of the cavity reinforcement 23. After that, rivet the rivet nut on the third wall panel 233 of the cavity reinforcement 23, put one end of the slider 731 on the column of the rivet nut and then tighten the screws to fix it, so that 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 panel 233, and it is easier for workers to assemble, thereby improving assembly efficiency.

[0085] In this embodiment, if Figure 1 and Figure 9 As shown, inner glass 5 is installed on the left and right ends of the front side of the smoke collecting chamber 2. Each inner glass 5 extends outward in the left and right directions and 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 smoke.

[0086] Further, if Figure 9 As shown, the smoke collecting chamber 2 also includes an inner glass bracket 24 located at the left and right ends. The inner glass bracket 24 is an L-shaped structure, including a first part and a second part connected vertically. The first part of the inner glass bracket 24 is overlapped and connected to the outside of the first wall panel 231 of the cavity reinforcement 23. The first part can be fixed to the cavity reinforcement 23 by snapping, screwing or gluing. The inner glass 5 is connected to the first part and fixed by gluing. The second part of the inner glass bracket 24 blocks the outside of the cavity reinforcement 23 in the left and right directions, and can block the slider 731, the swing arm bracket 7123 and the fourth swing arm 7122 connected to the cavity reinforcement 23, thereby playing an aesthetic role.

[0087] In this embodiment, if Figure 4 As shown, a spacer block 733 is fixed to the side of the inner panel 13 near the smoke collection chamber 2, and the guide rail 732 is fixed to the spacer block 733. The spacer block 733 is used to raise the guide rail 732, so that a certain gap is left between the guide rail 732 and the inner panel 13. This allows the second portion of the inner glass bracket 24 to avoid the guide rail 732 after the smoke collection chamber 2 is fully closed. After the smoke collection chamber 2 is fully closed, the second portion of the inner glass bracket 24 is accommodated in the gap between the guide rail 732 and the inner panel 13.

[0088] Furthermore, in this embodiment, Figure 1 and Figure 10As shown, the smoke collection mechanism also includes a flap 3, which is movably connected to the smoke collection cavity 2 and can be flipped relative to the smoke collection cavity 2. In the working state, the flap 3 and the smoke collection cavity 2 are open relative to the shell 1. When opened, the smoke collection cavity 2 flips outward relative to the shell 1 and simultaneously produces an outward sliding displacement in the horizontal or inclined direction, so that the smoke collection area extends forward, thereby expanding the coverage of the smoke collection area. At the same time, the flap 3 flips to the maximum angle relative to the smoke collection cavity 2 to further expand the smoke collection area, effectively improving the smoke collection efficiency, helping to prevent oil smoke from escaping, and improving the cleanliness and air quality of the kitchen; in the non-working state, the flap 3 and the smoke collection cavity 2 are closed relative to the shell 1, so that the smoke collection cavity 2 is hidden in the shell 1, and the flap 3 covers the front side of the shell 1 and shields the first smoke inlet 221, which is beautiful and neat.

[0089] The top of the flap 3 is rotatably connected to the top of the smoke collection chamber 2. This arrangement allows the bottom of the flap 3 to open relative to the smoke collection chamber 2 when the flap 3 is fully opened, thereby better absorbing 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 alternative embodiments, the top of the flap 3 can also be rotatably connected to the smoke collection chamber 2 via a hinge or a rotating shaft.

[0090] It should be noted that the top of the first wall panel 231 of the cavity reinforcement 23 extends laterally and is overlapped on the rear side of the top of the smoke collecting chamber body 21. One end of the hinge 31 is riveted to the flap 3 through a semi-hollow rivet, and the other end is fixed to the top of the smoke collecting chamber body 21 and the first wall panel 231 at the same time through a rivet nut and screw, thereby strengthening the structural strength of the top of the smoke collecting chamber body 21 and preventing deformation.

[0091] Furthermore, when the flap 3 and the smoke collecting cavity 2 are fully opened, an angle is formed between the flap 3 and the smoke collecting cavity 2, and a smoke collecting area is formed, and the value range of the angle is 0° to 180°. Optionally, the value range of the angle is 55° to 95°. Specifically, the angle can be 55°, 60°, 65°, 70°, 75°, 80°, 85°, 90° or 95°. Figure 3 As shown, in this embodiment, the angle is preferably 77°. At this time, the maximum depth of the smoke-collecting area is about 397 mm, and the smoke-collecting area is relatively large.

[0092] In this embodiment, if Figure 10As shown, the housing 1 resembles a rectangular parallelepiped, with the front side of the housing 1 forming a vertical plane. When fully closed, the flap 3 is upright, affixed to and completely covering the front side of the housing 1. This makes the side-suction range hood more compact and thinner when not in use, reducing space requirements and facilitating embedded installation. From the front, the flap 3 forms a complete, seamless, flat surface, making it easy to clean and enhancing the overall aesthetics of the range hood, distinguishing it from traditional and industry-standard range hoods.

[0093] In this embodiment, if Figure 11 As shown, the flap 3 is a flat structure extending in the vertical direction and is made of glass. When the smoke collecting cavity 2 and the flap 3 are in the fully closed state, the flap 3 remains parallel to the wall and completely covers the smoke collecting cavity 2, presenting a flat appearance and visually achieving a thinner body size. In this embodiment, when the smoke collecting cavity 2 and the flap 3 are in the fully closed state, the thickness of the smoke collecting mechanism is about 142 mm and the height is about 230 mm, which is relatively small in size, realizing the combination of a small body and a large smoke collecting area. Under the premise that the size of the smoke collecting mechanism is relatively small (such as 142 mm wide and 230 mm high), a larger smoke collecting size (such as 397 mm) is achieved.

[0094] It should be noted that the range hood can be installed in a non-embedded manner, directly against the wall, or embedded, that is, the main box 8 is embedded in the cabinet, and the smoke collection mechanism is exposed below the cabinet. The design of the overall size of the machine fully considers the actual size requirements of the home cabinet. For example, refer to Figure 11 The depth of a general cabinet is 350mm, the thickness of the cabinet door panel is about 20mm, and the remaining available installation depth is about 330mm. Therefore, the front and rear dimensions of the main box 8 or the decorative cover 9 are designed to be about 325mm, which meets the installation requirements while being neat and beautiful.

[0095] Optionally, in the working state, the smoke collecting cavity 2 can be selectively opened according to the requirements of the cooking state. For example, in the stewing state, only the flap 3 can be opened without opening the smoke collecting cavity 2; in the stir-frying state, the smoke collecting cavity 2 and the flap 3 are fully opened.

[0096] Optionally, in the working state, the smoke collecting cavity 2 can also be always fully opened, and the opening state of the flap 3 can be selected according to the requirements of the cooking state, such as half opening the flap 3 in the stewing state and fully opening the flap 3 in the stir-frying state.

[0097] In this embodiment, if Figure 5As shown, the shell 1 also includes a top plate 15 located on the upper side, a bottom plate 14 located on the lower side, and a back plate 17 located on the back side. The top plate 15 and the bottom plate 14 are spaced apart from each other, and the two outer plates 12 are respectively connected to the left and right sides of the top plate 15 and the bottom plate 14. The back plate 17 is connected to the back sides of the top plate 15, the bottom plate 14 and the outer plates 12, thereby forming a shell 1 with a structure similar to a rectangular body.

[0098] like Figure 12 As shown, the side-suction range hood also includes an oil cup 4, which is detachably connected to the bottom of the bottom plate 14 of the shell 1. The vertical projection of the bottom edge of the smoke collecting cavity 2 is located within the range of the oil cup 4, so that all oil droplets on the front side of the smoke collecting cavity 2 can enter the oil cup 4. The flap 3 can block the front side of the oil cup 4 when it is fully closed, so that the oil cup 4 is hidden in the flap 3 and is not easily seen, which not only improves the overall aesthetics, but also facilitates daily cleaning of the flap 3.

[0099] Optionally, the oil cup 4 is mounted on the bottom of the base plate 14 in a forward and backward pulling manner, which facilitates the removal and cleaning of the oil cup 4. The pulling manner of the oil cup 4 belongs to the prior art and will not be described in detail here.

[0100] In an optional embodiment, if Figure 10 As shown, each outer panel 12 includes an inclined panel 121 and a straight panel 122. The two inclined panels 121 on the left and right sides gradually tilt in opposite directions from back to front. The straight panel 122 is connected to the front side of the inclined panel 121 and is arranged at an angle with the inclined panel 121. The straight panel 122 extends in the front-to-back direction. In other words, the distance between the two outer panels 12 gradually narrows from front to back, making the housing 1 visually smaller and reducing space occupation.

[0101] In another optional embodiment, the outer plate 12 may also be a flat plate structure extending in the vertical direction, and the shell 1 may be a regular rectangular parallelepiped structure for ease of manufacturing.

[0102] In this embodiment, the bottom of the outer plate 12 is lower than the oil cup 4 to cover the left and right sides of the oil cup 4, so that the left and right sides of the oil cup 4 are also hidden, thereby improving the overall aesthetics.

[0103] Combine Figure 1 and Figure 13 The outer panel 12 is provided with an ambient light assembly 16, which 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 exposed outside the outer panel 12. The ambient light body 162 mainly serves as lighting and decoration, improving the aesthetics. The ambient light bracket 161 is versatile, and users can replace the ambient light body 162 according to their own lighting needs (such as color, brightness, or style).

[0104] like Figure 2 As shown, a sealing strip 27 is provided at the top of the smoke collecting chamber 2. When the smoke collecting 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 collecting chamber 2 and the top inner side of the top plate 15. This arrangement can effectively prevent oil smoke from escaping from the gap between the top of the smoke collecting chamber 2 and the top plate 15.

[0105] Furthermore, if Figure 2 As shown, the top of the flap 3 is provided with a flange 32. When the flap 3 is fully opened, a gap is formed between the top of the flap 3 and the top of the smoke collecting chamber 2, and the flange 32 blocks the upper side of the gap. This arrangement can effectively prevent oil smoke from escaping from the gap between the top of the flap 3 and the top of the smoke collecting chamber 2.

[0106] Specifically, the flange 32 is provided on the rear side of the flap 3. When the flap 3 is fully closed, the flap 3 completely blocks the flange 32, thereby preventing the escape of oil smoke while ensuring aesthetics.

[0107] like Figure 5 As shown, a cylindrical stopper 151 is provided on the inner side of the top plate 15. When the smoke collection chamber 2 is fully opened, the stopper 151 abuts against the rear end of the upper sidewall of the smoke collection chamber 2. Because the smoke collection chamber 2 is heavy, the stopper 151 abuts against the rear end of the upper sidewall of the smoke collection chamber 2 when the smoke collection chamber 2 is fully opened, preventing the smoke collection chamber 2 from sagging after opening. Optionally, the number of stoppers 151 can be one, two, or more in the left-right direction, without specific limitation.

[0108] like Figure 1 As shown, the smoke collecting chamber 2 also includes an oil net 22. A mounting port is provided on the front side of the smoke collecting chamber body 21. The oil net 22 covers the mounting port, and a plurality of first smoke inlets 221 are provided on the oil net 22. The oil smoke generated during cooking contains a large amount of grease particles. If the grease directly enters the fan, it will adhere to the core components such as the motor and blades, resulting in increased operating resistance, increased noise, and even damage. As the first line of defense, the oil net 22 filters these oil droplets through dense holes to prevent them from directly entering the range hood or adhering to the fan blades, thereby reducing the accumulation of oil stains on internal parts. The filtered air is cleaner and can effectively reduce grease pollution in the internal pipes of the range hood and the external environment.

[0109] Optionally, in this embodiment, the oil screen 22 is magnetically mounted on the smoke collecting chamber body 21, making it easy to remove and clean it separately. In other optional embodiments, the oil screen 22 can also be detachably mounted by snap-fitting or screwing, which is not specifically limited here.

[0110] Optionally, two mounting openings are provided on the front side of the smoke collecting chamber body 21, which are spaced apart in the left-right direction, and each mounting opening is provided with an oil net 22. In this way, each oil net 22 can correspond to a stove, achieving precise smoking and improving smoking efficiency.

[0111] Furthermore, when the smoke collecting cavity 2 is opened, a second smoke inlet 11 is formed between the bottom of the smoke collecting cavity 2 and the bottom of the housing 1. This can further increase the air intake area and further improve the smoke intake efficiency.

[0112] Optionally, a flexible net is provided at the second smoke inlet 11, one end of the flexible net being detachably connected to the bottom of the smoke collecting chamber 2, and the other end being detachably connected to the bottom of the housing 1. When the smoke collecting chamber 2 is open, the flexible net is unfolded to filter the oil smoke at the second smoke inlet 11, reducing the accumulation of oil and dirt on internal components. When the smoke collecting chamber 2 is closed, the flexible net can be folded without affecting the closure of the smoke collecting chamber 2 and the flap 3.

[0113] Furthermore, if Figure 13 As shown, the side-suction range hood further includes a first drive assembly 6, which is used to drive the flap 3 to flip relative to the smoke collection chamber 2 when opening or closing. In this way, by having two sets of drive assemblies independently drive the flap 3 and the smoke collection chamber 2, the stability of the flap 3 and the smoke collection chamber 2 can be ensured. At the same time, compared with a solution that uses a single drive mechanism to drive the flap 3 and the smoke collection chamber 2 simultaneously, the drive mechanism structure is avoided from being too complex and occupying more internal space in the vertical direction, which helps to reduce the longitudinal size of the range hood and save kitchen space.

[0114] Specifically, the first drive assembly 6 is installed in the middle of the smoke collecting chamber 2, and the second drive assembly 7 is installed on the left and right sides of the housing 1. By properly arranging the positions of the first drive assembly 6 and the second drive assembly 7, the space occupied by the two can be reasonably allocated. Moreover, by arranging the first drive assembly 6 and the second drive assembly 7 along the transverse direction of the range hood, the longitudinal size of the range hood can be reduced.

[0115] like Figure 16 As shown, the first drive assembly 6 includes a first motor 61 and a first swing arm group 62. The first motor 61 is arranged in the smoke collecting chamber 2. One end of the first swing arm group 62 is connected to the output shaft of the first motor 61, and the other end passes through the smoke collecting chamber 2 and is hingedly connected to the back of the flap 3. When the output shaft of the first motor 61 rotates, it drives the first swing arm group 62 to rotate, and the first swing arm group 62 drives the flap 3 to flip relative to the smoke collecting chamber 2 to open or close. This drive structure has the advantages of simple structure, high control accuracy, safety and reliability, compact structure and low maintenance cost. Optionally, in other embodiments, the first motor 61 can also be replaced by a drive cylinder.

[0116] The first motor 61 may be a Hall motor, which can be used to control the opening angle of the flap 3 according to cooking requirements, such as three gear adjustments: fully closed, half open, and fully open.

[0117] Specifically, if Figure 16 As shown, the first swing arm group 62 includes a first swing arm 621 and a second swing arm 622. One end of the first swing arm 621 is connected to the output shaft of the first motor 61, and the other end is hinged to one end of the second swing arm 622. The other end of the second swing arm 622 passes through the front side of the smoke collecting chamber 2 and is hinged to the back of the flap 3. Specifically, when the output shaft of the first motor 61 rotates, the first motor 61 drives the first swing arm 621 to rotate, the first swing arm 621 drives the second swing arm 622 to rotate, and the second swing arm 622 drives the flap 3 to rotate to open or close. By adopting the above-mentioned swing arm structure, when the flap 3 is closed, the first swing arm 621 and the second swing arm 622 are folded, occupying a small space. When the flap 3 is opened, the first swing arm 621 and the second swing arm 622 are extended to a longer length, thereby opening the flap 3 to a specific angle to meet a larger smoke collection area.

[0118] Further, combined with Figure 14 and Figure 16 As shown, a protective cavity 251 is provided at the rear side of the smoke collection chamber 2, and a through-hole 211 is provided at the front side of the smoke collection chamber 2, communicating with the protective cavity 251. The first motor 61 is mounted within the protective cavity 251, as is the first swing arm 621. The second swing arm 622 extends through the through-hole 211 and connects to the back of the flap 3. By mounting the first motor 61 within the protective cavity 251 at the rear side of the smoke collection chamber 2, the smoke is isolated from the outside, minimizing direct contact between the smoke and the first motor 61. This extends the service life of the first motor 61, and thereby the service life of the side-suction range hood.

[0119] Furthermore, if Figure 1 and Figure 15 As shown, the through-hole 211 is blocked with an elastic seal 212, which can be a rubber part. The elastic seal 212 is provided with a cutout, and the output end of the first drive component 6 is passed through the cutout and connected to the back of the flap 3. The cutout is sealed and wrapped around the outside of the second swing arm 622 to prevent oil smoke from entering the protective cavity 251 through the through-hole 211 and adhering to the first motor 61, thereby increasing its operating resistance, increasing noise, or even damaging it.

[0120] Specifically, if Figure 15As shown, the cutouts include multiple transverse cutouts 2121 and one longitudinal cutout 2122. The longitudinal cutout 2122 extends through the transverse cutouts 2121 along the length of the elastic seal 212, forming a plurality of tightly fitting sealing teeth 2123 at the cutouts. These sealing teeth 2123 can be sealed around the outside of the second swing arm 622. First, each sealing tooth 2123 can deform independently to adapt to the motion trajectory of the second swing arm 622, ensuring more uniform sealing contact. Second, the edges of the sealing teeth 2123 can scrape off oil stains adhering to the surface of the second swing arm 622 as it moves, preventing them from entering the interior. Third, this cutout shape distributes the load across the multiple sealing teeth 2123, avoiding localized stress concentration caused by long cutouts and reducing the risk of tearing or deformation.

[0121] In an optional embodiment, the orthographic projection of the perforation 211 on the elastic seal 212 falls within the range of the elastic seal 212, and the elastic seal 212 is fitted on the front side of the smoke collecting chamber 2 and completely covers the perforation 211. This arrangement can achieve a good seal between the elastic seal 212 and the perforation 211, preventing oil smoke 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 collecting chamber 2 by bonding, snapping or screwing, which is not specifically limited here.

[0122] In another optional embodiment, the elastic seal 212 may also be interference fit with the perforation 211. This can also achieve good sealing of the perforation 211 by the elastic seal 212, preventing oil smoke from entering the protective cavity 251 through the gap between the perforation 211 and the elastic seal 212.

[0123] Further, if Figure 14 As shown, in the left-right direction, the protective cavity 251 is located in the middle of the smoke collecting chamber 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 evenly stressed, allowing the left and right sides of the flap 3 to be pushed out synchronously when opening, preventing jamming and ensuring synchronous and stable movement.

[0124] It should be noted that, optionally, the smoke chamber body 21 is formed by enclosing a first plate at the front and a second plate at the rear and then riveting them together, which facilitates the processing of a single component. The oil net 22 is installed on the front side of the first plate, and a vent is opened on the rear side of the second plate to facilitate the flow of oil smoke into the main box 8. Figure 9 As shown, the smoke collecting chamber 2 further includes a partition 25 . The partition 25 is U-shaped. A through hole is provided in the middle of the second plate. The partition 25 is installed at the through hole. The internal space of the partition 25 forms the above-mentioned protective cavity 251 .

[0125] Further, if Figure 14As shown, the protective cavity 251 divides the interior space of the smoke collection chamber 2 into two separate left and right smoke collection areas. An oil screen 22 is installed on the front side of each smoke collection area. In this way, each smoke collection area can correspond to a stove, achieving precise smoking and improving smoking efficiency.

[0126] Further, combined with Figure 14 and Figure 17 As shown, the first drive assembly 6 also includes a mounting bracket 63, and the mounting bracket 63 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, and 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 collecting cavity 2 and is fastened thereto. The third plate 633 is connected to the second plate 632 and extends into the protective cavity 251 and is fastened thereto with the first motor 61.

[0127] First, the mounting bracket 63 is used to fix the first motor 61, and the cover is arranged at the opening of the protective cavity 251 to isolate the oil smoke; secondly, since the flap 3 is heavy, if the strength of the mounting bracket 63 is insufficient, the mounting bracket 63 and the entire smoke collecting cavity 2 will be deformed during the opening of the flap 3. Therefore, by abutting and installing the second plate 632 of the mounting bracket 63 on the rear side of the smoke collecting cavity 2, its structural strength can be ensured.

[0128] Specifically, if Figure 17 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 an avoidance opening 252. At least part of the first motor 61 is opposite to the second plate 632 to play a protective role, and the first swing arm group 62 is opposite to the avoidance opening 252.

[0129] When the flap 3 is completely closed, the hinged part of the folded first swing arm 621 and the second swing arm 622 can be extended from the avoidance opening 252 to play a avoidance role; 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 it is removed from the wall, and the screw connecting the first swing arm 621 and the output shaft of the first motor 61 is exposed at the avoidance opening 252. At this time, the worker can loosen the screw with a wrench to release the constraint on the flap 3, so that the flap 3 can be opened smoothly, and then subsequent maintenance operations can be carried out. If the first motor 61 fails, the mounting bracket 63 can be removed at this time, and the first motor 61 can be repaired or replaced, making the machine easy to maintain.

[0130] Alternatively, as Figure 17As shown, the front end of the first plate 631 is provided with a claw 6311 that can be inserted into and abut against the bottom of the upper side wall of the smoke collection chamber 2. When the smoke collection chamber 2 is fully opened, the front side of the first plate 631 is an exterior component and requires maintenance. Driving screws there is inconvenient and unsightly, so the claw 6311 is used to prevent the first plate 631 from warping, while also ensuring both aesthetics and ease of maintenance.

[0131] Alternatively, as Figure 18 As 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 position and support the first plate 631 when the mounting bracket 63 is installed, ensuring the stability of the connection of the first plate 631.

[0132] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
