[0002] This application claims priority to Chinese patent application CN202510330855.9, filed on March 19, 2025, entitled “Rainbow Hood”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This utility model relates to the field of kitchen appliance technology, specifically to a range hood. Background Technology

[0004] As a kitchen appliance, a range hood is mainly used to remove oil, heat, and other substances carried by ovens, cookware, etc., during the cooking process from the kitchen space in a timely manner, thereby ensuring the air quality in the kitchen.

[0005] Some current models feature a flap mechanism on the range hood that can be opened and closed. The flap is open when the range hood is in operation and closed when it is not. However, because the flap mechanism is relatively heavy, it generates some noise during the opening and closing process, which can negatively impact the user experience to some extent. Summary of the Invention

[0006] The present invention aims to solve at least part of the above-mentioned technical problems and / or solve at least part of the above-mentioned technical problems, specifically, how to minimize the noise generated by the flap assembly during the switching of its open and closed states.

[0007] In view of the above, the present invention provides a range hood, the range hood comprising: a range hood body having a chamber; a hinge assembly disposed on the range hood body; and a flap assembly disposed on the range hood body in an openable and closable manner by means of the hinge assembly; wherein, the hinge assembly comprises: a hinge bracket disposed on the range hood body in a multi-point connection manner; a drive mechanism disposed on the hinge bracket; and a swing arm assembly, the drive mechanism driving the flap assembly to move by driving the swing arm assembly.

[0008] In this way, since the hinge bracket is set in the range hood body in a multi-point connection manner, the noise generated by the flap assembly can be conducted through solids, thus reducing the noise of the flap assembly during opening and closing to a certain extent.

[0009] It is understandable that those skilled in the art can determine the number of connection points and the specific location of the main body of the range hood corresponding to multiple connection points based on actual needs.

[0010] In one possible implementation of the aforementioned range hood, the hinge bracket includes a hinge bracket body, which is fixedly connected to the range hood body at least at a position corresponding to the top of the range hood body using a multi-point connection method. For example, the position of the range hood body corresponding to the front can be a top plate or an integrally formed top and rear plate, etc.

[0011] In one possible implementation of the aforementioned range hood, the hinge bracket body has a first folded edge extending from a position corresponding to the front of the range hood body, and the first folded edge is fixedly connected to the front position of the range hood body. For example, the front position of the range hood body could be a folded edge extending from the top plate or the first / second side plate at a corresponding position.

[0012] In one possible implementation of the aforementioned range hood, the main body of the range hood includes an oil-collecting component, and the hinge bracket is fixedly connected to the oil-collecting component. Alternatively, the hinge bracket body can be directly connected to the oil-collecting component, or a structure adapted to the oil-collecting component can be provided on the hinge bracket body. Furthermore, the hinge bracket can be fixedly connected to the oil-collecting component at any reasonable position.

[0013] In one possible implementation of the above-mentioned range hood, the oil receiving component is provided with a hinge channel at a position corresponding to the hinge component, and the hinge bracket is fixedly connected to the oil receiving component at a position close to the hinge channel.

[0014] In one possible implementation of the above-mentioned range hood, the main body of the range hood includes a first side plate and a second side plate, the oil receiving assembly includes an oil receiving structure, the oil receiving structure is provided with an oil receiving connection structure near the first side plate and / or the second side plate, and the hinge channel is provided in the oil receiving connection structure.

[0015] In one possible implementation of the above-mentioned range hood, the hinge bracket body extends a second folded edge at a position corresponding to the oil receiving component, and the second folded edge is fixedly connected to the oil receiving component.

[0016] In one possible implementation of the above-mentioned range hood, the drive mechanism includes a drive component and a reduction mechanism, wherein the drive component is connected to the swing arm assembly through the reduction mechanism.

[0017] By setting a deceleration mechanism, the flipping speed of the flap assembly is reduced, thus reducing noise.

[0018] In one possible implementation of the aforementioned range hood, the reduction mechanism includes a gear reduction mechanism. This gear reduction mechanism may include single-stage or multi-stage reduction mechanisms, and may consist of only a gear reduction mechanism or may include other reduction mechanisms. The type of gear reduction mechanism can be determined based on the transmission path, and may include, but is not limited to, spur gear pairs, bevel gear pairs, etc.

[0019] In one possible implementation of the range hood described above, the swing arm assembly includes a first swing arm and a second swing arm connected to each other, the power output end of the drive mechanism is connected to the first swing arm, and the second swing arm is connected to the flap assembly.

[0020] In a preferred embodiment of this invention, a hinge bracket with multi-point connections and a hinge assembly with a reduction mechanism such as a gear reduction mechanism are employed. During the opening and closing process of the flap assembly relative to the range hood body, the noise generated by the flap assembly is effectively reduced, improving the user experience. Furthermore, the hinge assembly is a single component located on one side of the cavity. In addition, due to the multi-point connections, besides the connection points with their own connecting structures, the other connection points are all located near the top (of the second part) of the range hood body, further reducing noise.

[0074] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. For example, although this embodiment is described in conjunction with a product form in which the flap assembly is located below the main body of the range hood, it is obvious that those skilled in the art can determine the relative position of the flap assembly and the main body of the range hood, the specific method by which the flap assembly opens and closes, etc., according to actual needs. For instance, the flap assembly can be located at any reasonable position, such as the front side or a portion of the bottom of the main body of the range hood.

[0075] It should be noted that in the description of this utility model, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element 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. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0076] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0077] Furthermore, to better illustrate this utility model, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this utility model can still be implemented without certain specific details. In some examples, the detailed structure and principles of ovens well-known to those skilled in the art are not described in detail, in order to highlight the main points of this utility model.

[0078] The following will refer to Figures 1 to 14 This utility model is described by at least a portion thereof.

[0079] In one possible implementation, the range hood 100 includes a range hood body 1, a flap assembly 2, and an image acquisition assembly 3. The range hood body 1 forms a chamber, and the flap assembly 2 is movably disposed on the range hood body 1 and can cover the chamber. When the range hood 100 is in operation, the flap assembly 2 is open relative to the chamber. Under the action of the fan in the range hood body 1, fumes and other gases in the kitchen space (such as above the stove) are drawn into the chamber and discharged through the exhaust assembly. This ensures air quality in the kitchen space, such as improving air cleanliness and preventing excessively high temperatures. The image acquisition assembly 3 is mainly used to acquire image data within its field of view, such as image data related to the current cooking process. Based on this, the operating parameters of the range hood 100 and / or the operating parameters of other equipment related to the current cooking can be adjusted, thereby optimizing cooking performance and improving the cooking experience. For example, the opening degree of the flap assembly 2 and the speed of the fan can be adjusted, as well as the relevant parameters of other equipment such as the firepower of the stove and the exhaust parameters of the oven can also be adjusted.

[0080] Since fumes and other gases typically possess a certain degree of turbidity and carry heat, in this embodiment of the invention, the image acquisition component 3 is positioned close to the flap assembly 2. This results in less gas flowing through the area of ​​the image acquisition component 31 when the range hood 100 is in operation, thus ensuring both cleanliness and temperature control. Specifically: Firstly, the image acquisition component 3 typically needs to be in a relatively clean state to ensure the reliability of the acquired image data; for example, oil stains on the outer surface of the casing may affect the acquired image data. Secondly, to ensure the operational reliability of the image acquisition component 31, the ambient temperature typically needs to be within a certain range (e.g., not exceeding 85°C).

[0081] It is understood that those skilled in the art can determine the structural form of the image acquisition component 3, the number of its components, and its placement near the flap assembly 2 according to actual needs. For example, the image acquisition component 3 can be placed on the outside or inside of the chamber. The image acquisition component 3 may include one or more components. If multiple components are included, they may all be placed on the outside or inside of the chamber, or some may be placed on the outside of the chamber and some on the inside. Taking the outer edge of the flap assembly 2 as roughly rectangular as an example, the image acquisition component 3 can be placed near the four edges of the rectangular structure or at any position within the plate surface of the flap assembly 2. Exemplarily, the flap assembly includes a pivot side, a free side 202 (opposite to the pivot side), and two structural sides located at both ends of the pivot side 201 / free side 202. The image acquisition component 3 can be placed at any position near the pivot side 201, the free side 202, and the structural sides. The image acquisition component 3 can be installed on the existing structure of the range hood body 1, or it can be an additional structure added to the range hood body 1 as a carrier for installing the image acquisition component 3. If necessary, the image acquisition component 3 can also be configured as a structure without a connection to the range hood body 1, such as fixing the carrier to another suitable location. For example, in this example, a hinge component is provided near the side of the flap assembly along its width direction. The hinge component can be fixed to the top of the first / second side plate of the second part or the base. Correspondingly, the free side can be understood as the side that gradually approaches the user during the opening of the flap assembly, or the side whose movement is consistent with the open state. Correspondingly, the pivot side should be the side opposite to the free side, moving in tandem with the movement of the free side. It is called the pivot side because in traditional flipping movements, a similar movement can be achieved by setting a pivot, hinge, or other mechanism at the position corresponding to the pivot side.

[0082] In this embodiment, the image acquisition component 31 is disposed within the cavity and located on the edge of the flap assembly 2 near its pivot side 201. Alternatively, the image acquisition component 31 may also be disposed at the lower part of the oil receiving structure 1251 such as the oil mesh (in which case, the image acquisition component 31 is near the free side 202 of the flap assembly 2), the middle part of the oil mesh (in which case, the image acquisition component 31 is near the inner surface of the flap assembly 2), or the outer side of the cavity (e.g., it may be disposed near the ambient light assembly 51, near the rear oil cup 127, near the sides, etc.).

[0083] In this example, the range hood body 1 is a height-adjustable structure more suitable for recessed installation. Specifically, the range hood body 1 includes an upper first part 11 and a lower second part 12. The second part 12 is height-adjustable, and the flap assembly 2 is located below the second part 12 in an openable manner. The upper first part 11 is fixed inside the cabinet. When the range hood 100 is in operation, the second part 12 moves downward relative to the first part 11, partially extending out of the cabinet. When the range hood 100 is not in operation, the second part 12 moves upward relative to the first part 11, retracting back into the cabinet. Thus, when the range hood 100 is not in operation, the entire range hood 100 is recessed into the cabinet. Obviously, this structural form is only an exemplary description of the range hood 100. Those skilled in the art can determine the structural form of the range hood 100, the setting position of the flap assembly 2 on the range hood body 1, etc., according to actual needs. For example, the range hood 100 can be a traditional top-suction range hood 100 (the range hood body 1 is in a fixed posture), a side-suction range hood 100, etc.

[0084] The flap assembly 2 can be in an open or closed state relative to the range hood body 1 through rotation, rotation combined with other movements, or other methods. Taking only the flipping motion (rotation along a certain axis) as an example, it can be flipped relative to any reasonable axis of the range hood body 1. Furthermore, those skilled in the art can use any reasonable pivot connection structure / component / mechanism (such as hinges, shafts, rotating modules (including gear pairs, etc.)) to achieve the flipping motion of the flap assembly 2 relative to the range hood body 1 according to actual needs. In other words, provided that the flap assembly 2 can switch between an open and closed state relative to the range hood body 1, this utility model does not limit the structure or corresponding movement method used for switching.

[0085] In one possible implementation, the flap assembly 2 includes a pivot side 201, which is connected to the range hood body 1 in an openable manner at a position corresponding to the pivot side 201. The image acquisition assembly 3 is disposed on the range hood body 1 near the pivot side 201 of the flap assembly 2. When the range hood 100 is not in operation, the flap assembly 2 can cover the bottom of the range hood body 1. The image acquisition assembly 3 can be disposed on the outside or inside of the cavity. In this example, the image acquisition assembly 3 is housed within the cavity, thus preventing fumes and other gases from the kitchen from reaching the surface of the image acquisition assembly 3 when the range hood 100 is not in operation, thereby ensuring the cleanliness of the image acquisition assembly 3.

[0086] In one possible implementation, the second part 12 includes a base 121 and a first side plate 122, a second side plate 123, and a front plate assembly 124 disposed on the base 121. In this example, the base 121 includes an integrally formed top plate and a rear plate (which may be referred to as a top and rear plate). Obviously, the base 121 can also be a generally frame structure, with the front plate assembly 124, the first side plate 122, the second side plate 123, the top plate, and the rear plate disposed on or integrally formed therewith. The first side plate 122 and the second side plate 123 are respectively positioned on both sides of the front plate assembly 124. The first side plate 122 and the second side plate 123 can be fixedly connected to the base 121 by means such as internal screws. During assembly, the connection points between different parts requiring screws can be beveled to facilitate screw fixing. In this embodiment, a wiring space 1211 is provided or formed on the inner side of the second part 12, and related wiring harness components (such as wiring harnesses related to the image acquisition component 3 and the lighting component 4) are disposed in the wiring space 1211. For example, in this example, a wiring groove is fixedly provided on the rear inner side of the base 121 near the top, and the wiring groove and the base 121 form the wiring space 1211 for the wiring harness components.

[0087] In one possible implementation, the image acquisition component 3 includes an image acquisition part 31, such as a camera component. In this example, an image acquisition bracket 32 ​​is provided inside the cavity of the range hood body 1, and the image acquisition part 31 is disposed on the image acquisition bracket 32. For example, a first mounting position 321 is provided on the image acquisition bracket 32, and the image acquisition part 31 is disposed at the position of the image acquisition bracket 32 ​​corresponding to the first mounting position 321. When the flip-up assembly 2 is open, the image data acquired by the image acquisition part 31 can determine whether the pot placed on the stove has overflowed, dry-burned, or other phenomena.

[0088] In this example, when assembled, the image acquisition component 31 is roughly positioned in the middle of the range hood 100, and the installation direction of the image acquisition component 31 is roughly vertical, that is, the image acquisition component 31 acquires cooking-related image data in a way that "directly looks" at the area directly below it.

[0089] Regarding the viewing angle that the image acquisition component 31 can capture, it should reliably capture image data related to all stove heads in both the depth and width directions (the direction of the stove's depth / width). For example, the viewing angle of the image acquisition component 31 in both the depth and width directions can cover the depth / width dimensions of the stove surface. In a specific example, using a stove width of 800mm and a depth of 450mm as a baseline, the viewing angle along the width direction can cover a stove surface range of 1902mm. Correspondingly, the viewing angle (the angle formed between the left and right viewing angles) that the image acquisition component 31 can capture in the width direction is 102°. The dimension along the depth direction can cover a stove surface range of 784mm. Correspondingly, the viewing angle (the angle formed between the front and rear viewing angles) that the image acquisition component 31 can capture in the depth direction is 53.4°. Obviously, those skilled in the art can flexibly adjust the viewing angle range of the image acquisition component 31 according to actual needs. For example, the camera can capture image data within its field of view in a diagonal downward direction from front to back (e.g., at an angle of 60-90° with the horizontal direction).

[0090] Furthermore, in this example, the image acquisition bracket 32 ​​is fixedly mounted on the range hood body 1, and the image acquisition component 31 is mounted on the image acquisition bracket 32 ​​in a fixed posture. Obviously, those skilled in the art can, according to actual needs, mount the image acquisition component 31 in a movable manner on the image acquisition bracket 32. For example, it can rotate relative to the image acquisition bracket 32 ​​within a certain range (e.g., the rotation dimension and range can be adjusted according to actual needs) to adjust the field of view of the image acquisition component 31. It can also move along the image acquisition bracket 32 ​​to acquire image data of different areas along the width of the cooktop. In addition, when necessary, the image acquisition bracket 32 ​​can be configured as a structure capable of movement relative to the range hood body 1 (e.g., rotation, telescopic movement) to better ensure the performance of the image acquisition component 3.

[0091] In one possible implementation, the camera assembly mainly includes an image acquisition part 311 (such as typically including a camera (image acquisition module) and a PCB board assembly (image acquisition module control board), on which a SOC (System-on-Chip) is disposed) and a housing 312. For example, the housing 312 is disposed on the image acquisition bracket 32, and the image acquisition part 311 is disposed on the housing 312 and is capable of acquiring cooking-related image data within a preset field of view.

[0092] In one possible implementation, the housing 312 includes a first housing 3121 and a second housing 3122 connected to each other. In this example, the first housing 3121 is a cover and the second housing 3122 is a back cover. The cover and the back cover form an installation space that can accommodate at least a portion of the image acquisition part 311. For example, a light-transmitting structure 3123 such as a lens is provided on the cover to ensure the cleanliness of the image acquisition part 311 while ensuring that the image acquisition part 311 can acquire image data through the lens.

[0093] For example, housing mounting structures 3124 are provided on both sides of the housing (along the length of the image mounting bracket). In this example, the housing mounting structure is a structure with mounting holes extending from both ends of the housing (which may be called "ears"). Reinforcing ribs or other housing reinforcement structures are provided on the housing mounting structure to improve the strength of the "ears," effectively preventing breakage of the camera assembly when assembled. In this example, on one hand, a PDEM surface with a thickness of approximately 2mm is adhered to the outer edge of the housing near the PCB board assembly. Based on this, good sealing performance between the image acquisition part 311 and the housing can be ensured by squeezing cotton. On the other hand, multiple screw posts are provided on the housing. For example, first screw posts 3125 are provided on the housing at approximately the four corners corresponding to the rear cover. In this example, two screw posts are located on the inner side of the housing, and two screw posts are located on the outer side of the housing. In this way, a fixed connection between the housing and the rear cover can be achieved by the cooperation of screws and screw posts. For example, the housing has a receiving hole (a columnar hole of a certain length along the axial direction) on the side away from the rear cover that can be adapted to the front structure of the camera. Based on this, in this example, the installation process of the image acquisition component is roughly as follows: after inserting the bottom of the camera into the columnar hole, the camera can be pre-positioned on the housing. On this basis, the PCB board assembly is fixed to the housing by means of fasteners such as screws. For example, four second screw posts 3126 for fixing the PCB board assembly are provided in the housing. Then, the rear cover is fixed to the housing by means of the cooperation of the screws with the first screw posts. Finally, at the position corresponding to the ear, the image acquisition component is fixed to the position of the image acquisition bracket corresponding to the first mounting position by means of fasteners such as screws.

[0094] In one possible implementation, the image acquisition bracket 32 ​​serves as a mounting carrier for the image acquisition component, and its cross-section is approximately U-shaped. In this example, the middle portion of the U-shaped structure has a roughly V-shaped cross-section, with an obtuse angle formed between the two end structures at either end of the V-shape. The U-shaped structure has two second mounting positions 322 (approximately elongated holes) for mounting lighting lamps, and the aforementioned first mounting position 321 (approximately rectangular hole) for mounting the image acquisition component is approximately located between the two elongated holes. Clearly, those skilled in the art can determine the structural form of the image acquisition bracket and its first / second mounting positions according to actual needs, such as the middle portion of the U-shaped structure having a roughly planar cross-section.

[0095] For example, the inner side of the image acquisition bracket is provided with a first mounting structure 3211 (e.g., by welding) at the position corresponding to the rectangular hole. For example, the first mounting structure is a bracket of general strip structure and includes two brackets placed on both sides of the rectangular hole. The two ears on the housing and the brackets at the corresponding positions are fixedly connected by fasteners such as screws, thereby fixing the image acquisition component on the image acquisition bracket.

[0096] For example, a second mounting structure 3221 is provided on the inner side of the image acquisition bracket at the position corresponding to the elongated hole. For example, the second mounting structure is generally a U-shaped mounting bracket adapted to the rear side of the lighting lamp. If a claw is provided on the lighting lamp, the lighting lamp can be fixed on the image acquisition bracket by inserting the claw into the card hole provided on the mounting bracket.

[0097] Obviously, the aforementioned fixing methods and specific implementations of the fixing connections are merely exemplary descriptions. Those skilled in the art can determine the structural form of the image acquisition bracket, the fixing method of the image acquisition component / lighting lamp on the image acquisition bracket, etc., according to actual needs. Taking the fixing of the image acquisition component on the image acquisition bracket as an example, the fixing method of the image acquisition component can be changed from screw connection to snap connection, or other implementation methods can be used to achieve the screw connection between the image acquisition component and the image acquisition bracket, etc.

[0098] In one possible implementation, a smoke-collecting chamber is formed within the cavity, primarily for collecting smoke. For example, an oil-collecting assembly 125 is provided at the top corresponding to the smoke-collecting chamber. The oil-collecting assembly 125 may include an oil mesh, etc. An oil-collecting connecting structure 1252 is provided near the first / second side plate of the oil-collecting structure 1251, either fixedly connected or integrally formed. The oil-collecting connecting structure 1252 is generally a plate-like structure, and is fixedly connected to the corresponding first / second side plate. An oil-guiding assembly 126 is provided near the upstream side of the oil-collecting assembly 125. Exemplarily, the oil-collecting connecting structure 1252 is fixedly connected to the oil-collecting structure 1251 along the thickness direction on its inner side using fasteners such as screws (e.g., in this example, including two mounting holes). The oil-collecting connecting structure 1252 is fixedly connected along the thickness direction on the outer side to the lateral flange of the corresponding first / second side plate using fasteners such as screws (e.g., in this example, including one mounting hole). For example, the oil receiving assembly 125 is arranged at an angle downwards from front to back, and the oil guiding assembly 126 is arranged on the front side of the oil receiving assembly 125. The hinge assembly 21 is arranged on one of the two oil receiving connection structures 1252. The oil receiving connection structure 1252 with the hinge assembly can be called a maintenance plate. A hinge channel 12521 is provided on the maintenance plate. In this example, the hinge channel 12521 is approximately an elongated hole. The oil receiving connection structure 1252 is provided with an elastic structure 1253, such as a rubber part (with strip holes, mesh, etc.), in a removable manner at the position corresponding to the elongated hole, so as to prevent oil droplets from entering the smoke collection chamber from the larger elongated hole while ensuring the mobility of the hinge assembly.

[0099] In one possible implementation, the hinge assembly 21 includes a drive mechanism, a swing arm assembly, and a hinge bracket. The drive mechanism includes a drive component 211 and a reduction mechanism. The swing arm assembly includes an active swing arm 213 and a driven swing arm 214. The hinge bracket 215 is fixedly mounted on the range hood body 1. The drive mechanism is mounted on the hinge bracket 215. The drive component 211 is connected to the first end of the active swing arm via the reduction mechanism, thereby enabling the active swing arm to rotate. Exemplarily, the power output end of the reduction mechanism passes through a through hole in the hinge bracket 215 and is connected to the first end of the active swing arm. The second end of the active swing arm is pivotally (rotatably) connected to the first end of the driven swing arm. The second end of the driven swing arm is connected to the main body of the flap assembly (such as the movable glass flap).

[0100] For example, the first end of the active swing arm is roughly U-shaped, and the power output end of the drive mechanism passes through the two vertical sections of the U-shaped structure. A swing arm connection structure, such as an L-shaped bracket, is provided on the inner surface of the moving glass panel, and the second end of the driven swing arm is connected to the swing arm connection structure. Clearly, those skilled in the art can determine the structural form of the active / driven swing arm and its connection method with the drive mechanism / moving glass panel according to actual needs.

[0101] In one possible implementation, the reduction mechanism is a gear reduction mechanism, such as a three-stage gear reduction mechanism (e.g., a three-stage gearbox) in this example. This reduces noise because the flap assembly rotates slowly. Since the range hood generates noise during operation (fan rotation), and the flap assembly switches between open and closed states infrequently and for short periods, the noise issue is easily overlooked. The hinge assembly based on this invention significantly reduces the noise of the flap assembly. For example, driven by the hinge assembly, the flap assembly can open forward approximately 135°, increasing the width and height of the smoke collection area in front of the range hood. This ensures effective smoke collection even when the smoke collection chamber of the range hood is narrowed to fit the cabinet.

[0102] In one possible implementation, the hinge bracket 215 is disposed on the range hood body via a multi-point connection. In this example, the hinge bracket 215 includes a hinge bracket body 2151. The hinge bracket body 2151 has a first hinge bracket mounting hole 21531 at a position corresponding to the top of the base. In this example, there are three first hinge bracket mounting holes 21531. The hinge bracket body 2151 and the top of the base are fixedly connected to the first hinge bracket mounting holes 21531 by means of fasteners such as screws. The hinge bracket body 2151 extends downwards at a position corresponding to the front of the base with a first flange 21521. A second hinge bracket mounting hole 21532 is provided on the first flange 21521. In this example, there is one second hinge bracket mounting hole 21532. The front of the base also has a structure adapted to the first flange, and the two flanges are fixedly connected to the second hinge bracket mounting hole 21532 by means of fasteners such as screws. The hinge bracket body 2151 extends a second folded edge 21522 at a position corresponding to the repair plate, which is aligned with the surface direction of the repair plate. A third hinge bracket mounting hole 21533 is provided on the second folded edge 21522. In the example, the third hinge bracket mounting hole 21533 is one and is located on the repair plate near the hinge channel. The second folded edge and the repair plate are fixedly connected by fasteners such as screws and the third hinge bracket mounting hole 21533.

[0103] Obviously, the above-described hinge bracket structure and its corresponding five-point connection are merely exemplary descriptions. Those skilled in the art can flexibly adjust the number of connection points, their positions, and the objects to be connected according to actual needs, such as appropriately increasing or decreasing the number of connection points, or providing the hinge bracket with folded edges that can connect to the first / second side plates.

[0104] In one possible implementation, the oil guiding assembly 126 includes an oil guiding member 1261, which is generally a plate-like structure inclined downwards from front to back. Oil droplets reaching the chamber (such as those from the upper first portion 11) can be caught by the oil guiding member 1261 and guided to the downstream oil receiving assembly 125. Exemplarily, a number of notches (such as four in this example) are provided near the front of the base 121 to prevent the oil guiding member 1261 from being mounted and fixed on the base 121.

[0105] In one possible implementation, the oil guiding assembly 126 further includes a connecting member 1262. In this example, the connecting member 1262 is generally a strip-shaped structure and is fixedly disposed on the oil guiding assembly 1261. The image acquisition bracket 32 ​​is fixedly connected to the oil guiding assembly 1261 via the connecting member 1262. Exemplarily, the connecting member 1262 has a generally L-shaped cross-section. The first part of the L-shaped structure (the generally horizontally oriented part in the figure) is disposed on the oil guiding assembly 1261 by means of fasteners such as screws. The long side of the image acquisition bracket 32 ​​is disposed on the second part of the L-shaped structure (the generally vertically oriented part in the figure) by means of fasteners such as screws. Thus, the image acquisition bracket 32 ​​is fixedly connected to the oil guiding assembly 1261 via the connecting member 1262.

[0106] In one possible implementation, the base 121 is provided with a base reinforcement structure 1212, such as a reinforcing beam, at a position corresponding to the rear lower part. The base reinforcement structure 1212 is fixedly connected to the base 121, the first side plate 122, and the second side plate 123, respectively, to ensure that the second part 12 as a whole (the part near the bottom) has high strength. For example, the reinforcing beam includes an upper mounting part 12121, a lower connecting part 12122, and an intermediate part 12123 between the two. The mounting part is used to cooperate with the lower side of the oil receiving assembly, the connecting part is mainly used for the aforementioned fixed connection between the base and the first / second side plates, and the intermediate part can enhance the strength of the base reinforcement structure to a certain extent and enable the cooperation relationship between the mounting part and the connecting part. In this example, the mounting section is roughly a U-shaped structure with the opening facing the oil receiving component, the middle section is roughly a U-shaped structure with the opening opposite to the mounting structure, and the connecting section is roughly an L-shaped structure. The vertical part of the L-shaped structure is connected to the bottom of the rear plate of the base, and the two ends of the vertical part are fixedly connected to the rear inward flange of the first / second side plate.

[0107] Obviously, the above-described base reinforcement structure consisting of the mounting part, the connecting part, and the intermediate part is only an exemplary description. Those skilled in the art can determine its structural form and its connection relationship with the base / first side plate / second side plate according to actual needs. For example, it may include, but is not limited to: replacing the intermediate part with other structural forms such as an arc plate or a corrugated plate; the connecting part is directly a U-shaped structure with the inner side inclined inward, and the connecting part is directly connected to the mounting part (which can be considered as omitting the intermediate part); the two ends of the connecting part extend forward with flanges, and the flanges are fixedly connected to the inner or outer side of the first / second side plate.

[0108] In one possible implementation, the oil receiving assembly 125 is installed in the cavity (as in this example, the oil receiving assembly 125 is located in the portion of the cavity corresponding to the second part 12) as follows: a magnetic component is provided near the lower part of the oil guiding member 1261. As in this example, the magnetic component includes multiple magnetic parts. The mounting portion 12121 of the aforementioned reinforcing beam forms a strip-shaped groove as the mounting position for the oil receiving assembly. Obviously, the mounting position for the oil receiving assembly can also be an L-shaped structure, a multi-point mating structure, etc. In this way, the upper end of the oil receiving assembly 125 can be connected to the oil guiding member 1261 by magnetic adsorption (multi-point connection), and the lower end of the oil receiving assembly 125 can be inserted into the groove of the reinforcing beam. For example, the sidewall of the groove (the wall near the bottom) is provided with a first mating feature 12124, such as an upwardly protruding strip-shaped boss. Correspondingly, the lower surface of the lower end of the oil receiving assembly 125 is provided with a second mating feature 12125, such as multiple downwardly protruding bumps. In this way, by placing the bumps on the boss, a certain gap can be ensured between the oil receiving assembly 125 and the reinforcing beam in the assembled state. Obviously, the mating of the boss and multiple bumps is only an exemplary description. Other methods could also be two bosses, two opposing arc surfaces, or the boss and bumps being interchanged. The reinforcing beam is also provided with a connecting structure 12126, such as multiple connecting holes, to ensure that the oil droplets reaching the reinforcing beam can continue to flow smoothly to the oil cup 127 and other positions below. For example, hanging ears are provided at the lower rear of the second part 12 near both sides, such that the two hanging ears are arranged approximately symmetrically on the second part 12, and the oil cup 127 for receiving oil is removably provided on the second part 12 by means of the two hanging ears.

[0109] In one possible implementation, the range hood 100 includes a lighting component 4. In this example, the lighting component 4 is primarily used to provide illumination when the range hood 100 is in operation. Therefore, in this example, the lighting component 4 is located inside the cavity of the range hood body 1. Alternatively, the lighting component 4 can be located outside the cavity so that it can also provide illumination when the range hood 100 is not in operation.

[0110] In one possible implementation, the lighting component 4 is located within the cavity near the image acquisition component 31. Since the space within the cavity is relatively limited, it can be assumed that placing it in any location will provide some supplementary lighting. This provides supplementary lighting for the image acquisition component 31, ensuring the quality of the image data acquired by the image acquisition component 31, and thus guaranteeing the reliability of the control logic. In this example, the lighting component 4 is installed in the image acquisition bracket 32. Obviously, it can also be installed in other locations or structures, such as a separate mounting base or bracket, or directly on the range hood body 1, such as on the front wall, rear wall, or top.

[0111] In one possible implementation, the lighting assembly 4 includes a first lighting component 41 and a second lighting component 42, which are positioned on either side of the image acquisition component 31. This ensures that the image acquisition component 31 receives more uniform illumination when both the first lighting component 41 and the second lighting component 42 are operating. Furthermore, to address the varying illumination needs of different local areas of a person, the differentiated operation of the first lighting component 41 and the second lighting component 42 can also ensure the effective illumination of the image acquisition component 31.

[0112] In this example, the first lighting component 41 and the second lighting component 42 are roughly the same, such as both including long strip-shaped lighting lamps. They are arranged on both sides of the image acquisition component 31 in a roughly symmetrical manner. Obviously, those skilled in the art can flexibly select the number, structure, and setting position of the lighting components included in the lighting assembly 4 according to actual needs. In the case of multiple lighting components, the multiple lighting components can be the same or different.

[0113] In this example, the image acquisition bracket 32 ​​is a sheet metal bracket, which is entirely located inside the cavity. The lighting fixture is mounted on the sheet metal bracket by having holes in it and a locking claw at the rear. The lighting fixture is fixed to the sheet metal bracket by inserting the locking claw into the holes.

[0114] In one possible implementation, the image acquisition bracket 32 ​​is disposed on the second part 12 as follows: both ends of the image acquisition bracket 32 ​​are respectively disposed on the first side plate 122 and the second side plate 123, and the long side portion (upper part) of the image acquisition bracket 32 ​​is disposed on the aforementioned generally strip-shaped connecting member 1262. For example, the connecting member 1262 has a generally L-shaped cross-section. The first part of the L-shaped structure (the part arranged horizontally in the figure) is disposed on the oil guiding member 1261 by means of fasteners such as screws, and the long side portion of the image acquisition bracket 32 ​​is disposed on the second part of the L-shaped structure (the part arranged vertically in the figure) by means of fasteners such as screws. In this way, the image acquisition bracket 32 ​​can be fixedly connected to the oil guiding member 1261 through the connecting member 1262. In this way, the image acquisition bracket 32, while serving as the mounting carrier for the lighting component 4 and the image acquisition component 31, is also fixedly connected to the oil guide component 1261, the first side plate 122, and the second side plate 123. Therefore, it pulls the structure of the second part 12 near the front, thereby increasing the strength of the second part 12.

[0115] In one possible implementation, the image acquisition bracket 32 ​​is provided with a bracket reinforcement structure 33, such as a reinforcing plate. For example, in this example, the image acquisition bracket 32 ​​has the bracket reinforcement structure 33 located near its front outer side. The bracket reinforcement structure 33 is fixedly connected to the first side plate 122, the second side plate 123, and / or the base 121 near its front end. The rear end of the bracket reinforcement structure 33 is fixedly connected to the front end of the image acquisition bracket 32. Exemplarily, the front end of the bracket reinforcement structure 33 is fixed to the first / second side plate. For example, both the first side plate 122 and the second side plate 123 include a side plate main body portion 1231. The side plate main body portion 1231 extends inwardly at its front end with a side plate flange 1232. The front side edge of the bracket reinforcement structure 33 is fixedly connected to the side plate flange 1232 of the first / second side plate at positions corresponding to both ends. The bracket reinforcement structure 33 is also fixedly connected to the side plate main body portion 1231 of the first / second side plate at a position near the rear of the front end or at a position between the front and rear ends.

[0116] For example, the bracket reinforcement structure 33 has a first bracket reinforcement structure flange 331 and a second bracket reinforcement structure flange 332 extending from its front and rear portions, respectively, which are fixedly connected to the first / second side plates and the image acquisition bracket. The main body of the bracket reinforcement structure has mounting brackets 333, which are generally sheet-like structures, provided or extending near its two ends. Based on this, the fixed connection between the front portion of the bracket reinforcement structure 33 and the side plate flanges 1232 of the first / second side plates is as follows: after the first bracket reinforcement structure flange 331 covers the side plate flange 1232 from the front, the two are fixedly connected by fasteners such as screws. The fixed connection between the two ends of the bracket reinforcement structure 33 and the main body portions 1231 of the first / second side plates is as follows: the mounting brackets are fixedly connected to the corresponding side plate main body portions 1231 by fasteners such as screws. The fixed connection between the rear part of the bracket reinforcement structure 33 and the side plate flange 1232 of the first / second side plate is as follows: the flange 332 of the second bracket reinforcement structure and the flange at the front of the image acquisition bracket 32 ​​are fixedly connected by fasteners such as screws.

[0117] Obviously, the above-described structure of the bracket reinforcement structure 33 and its fixing method are only exemplary descriptions. Those skilled in the art can flexibly adjust it according to actual needs. For example, the front installation method may include, but is not limited to: having flanges processed at both ends of the bracket reinforcement structure, with the flanges directly fixed to the main body of the side plate; or having overlapping parts between the bracket reinforcement structure and the image acquisition bracket (such as adjusting the screw direction at the connection position, or increasing the strength of the image acquisition bracket by overlapping).

[0118] In this way, the support reinforcement structure not only improves the stability of the sheet metal support, but also increases the strength of the first / second side plates, thereby further increasing the structural strength of the front part of the second section. This can be manifested in ensuring the verticality and flatness of the first / second side plates.

[0119] In this example, when assembled, the lighting direction of the lamps is biased towards the lower rear of the range hood, that is, the lighting direction is tilted from top to bottom and from front to back. Obviously, those skilled in the art can flexibly adjust the lighting direction according to actual needs. For example, the lighting directions of the two lamps can be differentiated, or the lighting directions of the two lamps can be adjusted.

[0120] In one possible implementation, the range hood 100 also includes an ambient light assembly 51, which is positioned on the pivot side 201 of the range hood body 1 near the flap assembly 2. Just as the image acquisition component 31 is primarily used to acquire image data related to the current cooking process, the ambient light assembly 51 conveys information related to the current cooking process to the user (e.g., the operator). Therefore, the image acquisition component 31 can be completely housed within the cavity and does not need to be within the user's field of vision when in operation, while the light radiation range of the ambient light assembly 51 should extend into the user's field of vision.

[0121] In one possible implementation, the ambient light assembly 51 is positioned on the range hood body 1 at the bottom of the chamber. When the flap assembly 2 is closed, the ambient light assembly 51 is located on the side of the flap assembly 2 closest to the operator (front side). When the flap assembly 2 is open, the front ambient light assembly 51 can convey information related to the current cooking process to the user. Alternatively, the ambient light 512 can be positioned on the side of the range hood body 1 corresponding to the chamber, or the ambient light assembly 51 can be positioned on both the bottom and side of the range hood body 1 corresponding to the chamber.

[0122] In this way, when the range hood 100 is running, the ambient light 512 can provide users with a visual effect (such as a running light effect). Furthermore, while the range hood 100 is running, different effects can be provided based on its operating parameters; that is, a preset mapping relationship can be established between the ambient light 512, its effects, and the operating parameters of the range hood 100. Alternatively, the effect of the ambient light 512 can be adjusted based on the image data acquired by the aforementioned image acquisition unit 31; that is, a preset mapping relationship can also be established between the ambient light 512, its effects, and the image data related to the current cooking process.

[0123] In one possible implementation, the front panel assembly 124 includes a front panel glass 1242 and a front panel glass mounting base 1241. The front panel glass mounting base 1241 can be a plate-like structure, a bracket, etc. The front panel glass mounting base 1241 is fixedly connected to the first / second side panels, the bracket reinforcement structure 33, etc., thereby ensuring the overall strength of the front part of the second section 12. In this example, the front panel glass mounting base 1241 is generally a plate-like structure, and multiple mounting positions for the front panel glass 1242 are provided on the front panel glass mounting base 1241 to facilitate the installation of the front panel glass 1242 onto the front panel glass mounting base 1241. For example, the mounting position of the front glass 1242 is a small protrusion with a locking hole. A latching structure 1243 is provided on the back of the front glass 1242. If the latch is attached to the back of the front glass 1242 by adhesive, the front glass 1242 can be installed onto the front glass mounting base 1241 by inserting the latch into the locking hole on the small protrusion. Furthermore, the front glass mounting base 1241 has an elongated hole in the middle for easy maintenance / removal of the lighting fixture, and a notch in the upper right corner for easy maintenance / removal of the hinge assembly 21.

[0124] In one possible implementation, the ambient light assembly 51 includes an ambient light mounting base 511 and an ambient light 512. The ambient light mounting base 511 is fixedly connected to or integrally formed with the range hood body 1. For example, in this example, the ambient light mounting base 511 is fixedly mounted on the front panel assembly 124. The ambient light mounting base 511 forms an ambient light mounting space, within which at least a portion of the ambient light 512 is accommodated. This allows for a degree of embedded mounting of the ambient light 512 at the bottom of the range hood body 1, achieving a degree of "light without the lamp visible." The ambient light mounting space can be a circumferentially closed mounting cavity (with a light-transmitting structure on the bottom or a light-transmitting area), or a mounting groove with an open side.

[0125] In one possible implementation, both the ambient light mounting base 511 and the ambient light 512 are generally elongated structures. For example, the ambient light mounting base 511 is made by extruding aluminum profiles, and its cross-section matches the outline dimensions of the ambient light 512. The ambient light mounting base 511 is fixedly disposed at the bottom of the second part 12. In this example, the ambient light 512 can be inserted into the ambient light mounting space from one side. Obviously, other installation methods, such as pushing it in directly from bottom to top, can also be used.

[0126] In one possible implementation, the range hood body 1 further includes a trim assembly 52. ​​An ambient light mounting base 511 is fixedly connected to or integrally formed on the trim assembly 52, and the trim assembly 52 is fixedly mounted on the front panel assembly 124. Obviously, those skilled in the art can determine the structural form of the trim assembly 52, its fixing method to the front panel assembly 124, and the specific location for the fixed connection according to actual needs. For example, it can be fixedly connected to the bottom or back of the front panel assembly 124, or it can be fixedly connected to the front panel glass 1242 or the front panel glass mounting base 1241 of the front panel assembly 124.

[0127] In one possible implementation, the ambient light mounting base 511 and the trim assembly 52 are integrally formed, for example, by extruding aluminum profiles. The trim assembly 52 is fixedly connected to the front glass 1242 by adhesive bonding. Thus, after the ambient light 512 is installed onto the ambient light mounting base 511, the trim assembly 52 containing the ambient light assembly 51 is bonded to the front glass 1242 to form a glass assembly containing the ambient light 512. By snapping the glass assembly containing the ambient light 512 onto the front glass mounting base 1241, a front panel assembly 124 containing the ambient light 512 is formed.

[0128] In this example, the trim assembly 52 includes a first trim 521 and a second trim 522 located below the first trim 521. The front surface of the first trim 521 is located in front of the second trim 522 along its thickness direction (roughly forming a stepped surface), thus ensuring that the second trim 522 is approximately flush with the front surface of the front panel glass 1242 in the assembled state. In this example, a third trim 523 extends forward at the position corresponding to the stepped surface to provide a certain positioning function during the bonding process. The ambient light mounting base 511 is located on the back of the second trim 522, and the front part of the first trim 521 is bonded to the front panel glass 1242. It can be seen that the first trim functions as an adhesive part, the second trim functions as a mounting base for the ambient light assembly, and the third trim functions as a positioning part.

[0129] For example, a first adhesive structure, such as 3M double-sided tape, is provided near both ends of the first trim strip 521. Simultaneously, the first trim strip 521 and the front panel glass 1242 are connected to each other by a second adhesive structure. This second adhesive structure involves distributing glass glue between the first adhesive structures at both ends of the first trim strip 521. In this way, the first trim strip 521 and the front panel glass 1242 can be bonded to each other through multi-point bonding. It can be seen that in this example, with the assistance of double-sided tape, the trim strip assembly 52 (which may be referred to as the ambient light assembly 5) containing the ambient light component 51 can be better bonded to the glass panel. Obviously, those skilled in the art can determine the specific structural form of the trim assembly 52, the relative position of the ambient light assembly 51 and the trim assembly 52, and the connection method between the trim assembly 52 and the front panel assembly 124 according to actual needs. For example, the ambient light mounting base 511 is set on the back of the first trim 521, the first trim 521 and the second trim 522 are made of different materials (such as the second trim 522 being similar in material to the glass panel), the trim assembly 52 is fitted to the front panel glass 1242 on the stepped surface between the first trim 521 and the second trim 522 by means such as plugging / adhesion, and the trim assembly 52 is fixedly connected to the front panel glass mounting base 1241.

[0130] Compared to the second trim strip 522, the two ends of the ambient light mounting base 511 are recessed by a certain distance. Figure 12 In the case of the ambient light mounting base 511, a portion of each end is cut off by machining. In this way, when assembled, the two ends of the second trim strip 522 in the width direction are roughly flush with the outer surfaces of the first side plate 122 and the second side plate 123, while the two ends of the ambient light mounting base 511 roughly abut against the inner surfaces of the first side plate 122 and the second side plate 123. This achieves the limiting of the ambient light assembly 5 and at the same time protects the ambient light 512 in the ambient light mounting space 5111.

[0131] In one possible implementation, the ambient light assembly 51 is fixedly mounted to the front glass panel 1242 by adhesive bonding. For example, the ambient light assembly 51 has 3M double-sided adhesive near both ends, thus, in addition to the distributed application of silicone sealant, the double-sided adhesive provides additional bonding, reliably attaching the ambient light assembly 51 to the front glass panel 1242. Alternatively, the front panel bracket may also be fixedly connected to the front glass panel 1242 by adhesive bonding.

[0132] As can be seen, in the preferred embodiment of this invention, the hinge assembly is located near the side panel of the chamber, and the hinge bracket is mounted on the range hood body via multiple connection points (e.g., in this example, via the engagement of five screws with corresponding hinge bracket mounting holes). This results in a greater degree of noise transmission through solid surfaces during the switching of the flap assembly between open and closed states. Furthermore, the use of a speed reduction mechanism (such as a gear reduction mechanism) reduces the flipping speed of the flap assembly. Tests have shown that using the hinge assembly of this invention significantly reduces noise during the opening and closing motion of the flap assembly, improving a user experience that is often overlooked.

[0133] Furthermore, by equipping the range hood with an image acquisition component, the parameters of the range hood itself and / or other related equipment such as ovens and cooktops can be controlled based on the image data acquired by the noise-reducing acquisition component. For example, by associating multiple devices in the control logic, joint control of the kitchen space can be achieved. In this case, the image acquisition component acts as a "smart eye" serving the control logic of the joint control. By housing the image acquisition component within a cavity, it is ensured that the image acquisition component is relatively isolated from the air in the kitchen space when the range hood is not in operation, thus guaranteeing the cleanliness and temperature level of the image acquisition component.

[0134] Furthermore, by embedding an ambient lighting component near the bottom of the range hood body, it is expected to provide an ambient lighting effect to users in a way that is visible but not a light source. By integrating the ambient lighting mounting base and trim component into a single unit, different functional modules are integrated. Additionally, the first adhesive assembly is formed by bonding the ambient lighting assembly, including the ambient lighting component and trim component, to the front panel glass. This second adhesive assembly is then further bonded to the front panel glass mounting base. This approach is expected to optimize the installation process of the front panel assembly (including the ambient lighting assembly), improving installation convenience while ensuring installation reliability.

[0135] The technical solution of this utility model has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments.
