[0036] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0037] This utility model discloses a housing assembly for a range hood. Please refer to [link / reference]. Figures 1 to 4 ,include:

[0038] The housing 1 has a cavity, which is divided into an electronic control cavity a and a smoke collection cavity b. The housing 1 is provided with an air intake 11 that communicates with the smoke collection cavity b.

[0039] The rear cover plate 2 is connected to the housing 1 and is located above the smoke collection chamber b;

[0040] The front cover 3 is connected to the housing 1 and is used to open or close the electronic control cavity a.

[0041] In this invention, the electronic control cavity a is located closer to the operating side of the housing 1 than the smoke collection cavity b, i.e., the side where the user stands and operates. Functional components are installed within the electronic control cavity a. Specifically, the smoke collection cavity b is sealed by the rear cover plate 2, and the electronic control cavity a is sealed by the front cover plate 3, thus enclosing the functional components within the electronic control cavity a. The rear cover plate 2 and the front cover plate 3 together constitute the cover plate in the prior art.

[0042] When it is necessary to inspect, replace, or repair the functional components inside the electrical control cavity a, simply open the front cover plate 3 to open the electrical control cavity a and remove the functional components inside. At this time, it is not necessary to open the rear cover plate 2, which greatly simplifies the operation process and saves time and labor costs. This improves the technical problem that in the existing technology, when performing the disassembly, assembly, and repair of the functional components, it is necessary to disassemble, assemble, and repair the entire cover plate, which is quite troublesome, and improves convenience.

[0043] In this invention, the electrical control chamber a and the smoke collection chamber b are independent of each other, and the air intake 11 is connected to the smoke collection chamber b. The air intake 11 is used to draw out oil fumes. That is, the air intake 11 and the electrical control chamber a are independent of each other and are not connected. This ensures that during long-term use, oil fumes will only be drawn out at the smoke collection chamber b and will not enter the electrical control chamber a, thus ensuring the cleanliness of the electrical control chamber a and preventing oil fumes from damaging the functional components inside the electrical control chamber a. In addition, when the front cover 3 is opened to install or replace the functional components inside the electrical control chamber a, oil stains can be prevented from affecting the work of the operators, ensuring the cleanliness of the working environment.

[0044] Furthermore, by dividing the range hood into two independent cavities, the electrical control cavity a and the smoke collection cavity b, different functional components have their own dedicated spaces. For example, electrical control-related functional devices can be placed in the electrical control cavity a, while the smoke collection-related structures correspond to the smoke collection cavity b. This clear functional zoning helps to improve the structural rationality and operational stability of the entire range hood and reduces potential mutual interference between different functional components.

[0045] The rear cover 2 is connected to the housing 1 and located above the smoke collection chamber b, ensuring that the normal function of the smoke collection chamber b is not affected. The front cover 3 is designed to facilitate the maintenance of the electronic control chamber a. The two work together to achieve their respective functions and improve the overall performance of the range hood in terms of use and maintenance.

[0046] For the housing assembly of this utility model, please refer to [link / reference]. Figures 3 to 6 ,as well as Figures 11 to 12 The cavity of the housing 1 is provided with a partition plate 12, which divides the cavity into an electrically controlled cavity a and a smoke collection cavity b. The gas in the electrically controlled cavity a and the smoke collection cavity b are not connected.

[0047] By using the partition plate 12, the gas in the electrical control chamber a and the smoke collection chamber b are not connected, thus isolating the oil fumes in the smoke collection chamber b and preventing them from entering the electrical control chamber a and contaminating the functional components. This keeps the functional components clean for a long time, thereby improving the technical problem that existing range hoods are prone to damaging the functional components inside the chamber when fumes are emitted, leading to increased cleaning and replacement costs.

[0048] The partition plate 12 physically separates the electrical control chamber a and the smoke collection chamber b, providing better functional isolation and protection. For the electrical control chamber a, it prevents impurities such as oil fumes and dust that may be present in the smoke collection chamber b from entering, reducing corrosion and contamination of the electrical control components, extending the service life of functional components, and ensuring the stable operation of the electrical control system. For the smoke collection chamber b, it also avoids unnecessary interference to the smoke collection function caused by malfunctions in the electrical control components, further enhancing the independence and reliability of each functional module.

[0049] Furthermore, by setting a partition plate 12 inside the cavity of the housing 1 to divide the electrical control cavity a and the smoke collection cavity b, the division between the two cavities becomes clearer and more regular. The partition plate 12 can act as a physical partition, structurally stabilizing the boundary between the two cavities and preventing deformation or mutual interference of the two cavities due to external vibrations or other factors during use. This helps maintain the stability of the entire internal structure of the range hood and ensures the normal operation of all functions.

[0050] The housing assembly of this utility model has a partition plate 12 having a first connecting part 121, a second connecting part 122 and a third connecting part 123. The first connecting part 121 is located at the lower edge of the partition plate 12 and is sealed to the cavity wall. The second connecting part 122 is located at the upper edge of the partition plate 12 and is sealed to the rear cover plate 2. There are two third connecting parts 123, which are respectively located on both sides of the partition plate 12. Both third connecting parts 123 are sealed to the cavity wall.

[0051] The housing 1 has a bottom plate 13, a side plate 14 and a rear plate. The bottom plate 13, the rear cover plate 2, the side plate 14 and the rear plate form a cavity. The first connecting part 121 is sealed to the bottom plate 13 of the cavity, and the two third connecting parts 123 are sealed to the side plate 14 of the cavity.

[0052] By utilizing the surface contact sealing structure formed between the first connecting part 121 and the bottom plate 13, the surface contact sealing structure formed between the second connecting part 122 and the rear cover plate 2, and the surface contact sealing structure formed between the third connecting part 123 and the side plate 14, it is ensured that the oil fumes entering the smoke collection chamber b will not enter the electronic control chamber a through the various structural connections.

[0053] The partition plate 12 is sealed to the cavity wall via its lower edge first connecting part 121, its upper edge second connecting part 122 is sealed to the rear cover plate 2, and its sides third connecting parts 123 are sealed to the cavity wall, achieving a comprehensive seal. This effectively prevents impurities such as oil fumes and water vapor in the smoke collection chamber b from entering the electrical control chamber a, avoiding corrosion, short circuits, and other damage to the electronic components in the electrical control chamber. It also prevents heat and static electricity generated by the wiring in the electrical control chamber a from interfering with the normal smoke collection and exhaust functions of the smoke collection chamber b, ensuring the independence and stability of the two chambers' functions and minimizing any adverse effects between them.

[0054] Because the partition plate 12 achieves a good seal with the surrounding structure, during routine cleaning of the range hood, such as cleaning the smoke collection chamber b, it prevents grease and other dirt from spreading through gaps to the area where the electrical control chamber a is located. This makes the cleaning work more focused and specific, requiring only the smoke collection chamber b and its connected exposed parts to be cleaned. This reduces the complexity of cleaning and lowers the risk of accidentally touching components inside the electrical control chamber a due to improper cleaning, providing convenience for users. The sealed partition plate 12 avoids electrical safety problems caused by grease and moisture seeping into the electrical control chamber a. Safety hazards such as leakage and short circuits are effectively reduced, ensuring the electrical safety of the range hood during use. This allows users to use it with greater peace of mind, especially in the relatively humid and greasy environment of the kitchen, where this safety guarantee is particularly important.

[0055] The first connecting part 121 extends toward the direction of the smoke collection chamber b relative to the partition plate 12, and forms a surface contact sealing structure with the bottom plate 13. When oil accumulates in the smoke collection chamber b, the contact surface between the first connecting part 121 extending toward the direction of the smoke collection chamber b and the bottom plate 13 forms a barrier to prevent oil from spreading toward the electrical control chamber a. This barrier is a surface structure, and compared to the way the first connecting part 121 extends toward the electrical control chamber a in the opposite direction, the barrier structure has a larger partition area, and the protective effect of preventing oil from the smoke collection chamber b from entering the electrical control chamber a is better.

[0056] For the housing assembly of this utility model, please refer to [link / reference]. Figures 11 to 12 The second connecting part 122 is formed by extending forward from the upper edge of the partition plate 12. The second connecting part 122 extends into the electrical control cavity a. The rear cover plate 2 is connected to the second connecting part 122. The front edge of the rear cover plate 2 is provided with a fourth connecting part 21. The front edge and side edge of the front cover plate 3 are connected to the housing 1. The rear edge of the front cover plate 3 is connected to the fourth connecting part 21.

[0057] The upper edge of the partition plate 12 extending forward means that the upper edge of the partition plate 12 extends toward the user side of the range hood.

[0058] The cross-section of the second connecting portion 122 is in a "convex" shape, and a structure protruding upward is formed in the middle. The rear cover plate 2 is formed with a groove adapted to the second connecting portion 122 with the protruding structure. When the oil stain in the smoke collecting cavity b spreads from the contact surface between the second connecting portion 122 and the rear cover plate 2 towards the electric control cavity a, the protruding structure of the second connecting portion 122 forms a partition, and the path for the oil stain to spread into the electric control cavity a at this place bends upward, then horizontally, and then downward, forming a stepped oil smoke spreading path structure, with better sealing effect.

[0059] The second connecting portion 122 with a cross-section in a "convex" shape has two parallel plates and a U-shaped groove structure with a downward opening. One of the parallel plates is connected to the partition plate 12, and a surface contact type sealing effect is formed on the other parallel plate on the lower side of the fourth connecting portion 21. The trailing edge of the front cover plate 3 is connected to the fourth connecting portion 21, thereby forming a continuous sealing structure and forming a continuous and regular appearance structure, avoiding the situation that may affect the aesthetics such as unnatural connection and excessive gaps between the rear cover plate 2 and the front cover plate 3, making the overall appearance of the range hood more coordinated and unified, enhancing the overall texture and visual effect of the product, and meeting the requirements of consumers for the aesthetics of kitchen appliances.

[0060] For the housing assembly of the present utility model, please refer to Figures 3 to 4 , a plug-in hole 15 is provided at the leading edge of the part of the housing 1 corresponding to the electric control cavity a. The edge of the front cover plate 3 is provided with a downward extending extension edge 31, and a plug-in block 32 is provided on the part of the extension edge 31 located at the leading edge of the front cover plate 3. The front end of the front cover plate 3 is plugged into the plug-in hole 15 through the plug-in block 32.

[0061] When installing the front cover plate 3 to close the electric control cavity a, the plug-in block 32 is inserted into the corresponding plug-in hole 15 to achieve the plug-in installation of the front cover plate 3. Correspondingly, through this plug-in method, the front cover plate 3 can be quickly disassembled, which is simple to use and effectively saves the time cost of installation and disassembly.

[0062] The edge of the extension edge 31 is an arc surface structure and is matched with the inner wall structure at the opening of the electric control cavity a to achieve sealed installation. For some electric control components with high environmental requirements, good sealing can block the intrusion of external dust and moisture, reduce the probability of faults such as short circuits and corrosion of the components due to moisture and dust accumulation, and extend their service life.

[0063] In the housing assembly of the present utility model, the plane where the fourth connecting portion 21 is located is lower than the plane where the rear cover plate 2 is located, and a stepped surface is formed on the rear cover plate 2. The height of the stepped surface is adapted to the height of the extension edge 31, and the extension edge 31 abuts against the fourth connecting portion 21.

[0064] When the front cover plate 3 is installed, the extended edge 31 can precisely abut against the fourth connecting part 21, providing a clear positioning reference for the installation of the front cover plate 3. Operators can complete the assembly operation more quickly and accurately, reducing the time wasted due to repeated adjustments caused by misalignment and improving assembly efficiency. The extended edge 31 of the front cover plate 3 abuts tightly against the stepped surface of the fourth connecting part 21, forming a downward pressure on the fourth connecting part 21, which in turn causes the fourth connecting part 21 to press down on the other parallel plate of the second connecting part 122, thereby improving the sealing between the fourth connecting part 21 and the second connecting part 122.

[0065] In the housing assembly of this utility model, the front cover plate 3 and the part corresponding to the fourth connecting part 21 are provided with a recessed hole 33 for the connector to pass through, and the fourth connecting part 21 is provided with a connecting hole 211. The connector passes through the recessed hole 33 and connects with the connecting hole 211.

[0066] During the installation of the front cover plate 3, after inserting the plug block 32 into the corresponding plug hole 15, the extended edge 31 of the front cover plate 3 is fastened to the fourth connecting part 21. At this time, the connecting hole 211 and the corresponding recessed hole 33 are connected. Then, the connector is inserted into the recessed hole 33, and the connector passes through the recessed hole 33 and connects with the connecting hole 211, thereby achieving the fixed installation of the front cover plate 3. Furthermore, the connection between the connector and the connecting hole 211 enhances the stability of the overall structure. Even if the equipment is subjected to frequent vibration and shaking for a long time, it can prevent the front cover plate 3 from becoming loose or falling off, maintain the integrity of the equipment shell, ensure the stable operation of internal components, and ensure the durability of the seal by continuously subjecting the second connecting part 122 to pressure from the fourth connecting part 21 in the installed state.

[0067] The design of the recessed hole 33 allows the connector head to be recessed into the hole and not protrude from the surface of the front cover plate 3. On the one hand, this makes the front cover plate 3 look flatter and simpler, improving the overall aesthetics of the equipment; on the other hand, it avoids accidental collisions and scratches caused by the connector head being exposed, preventing damage to the connector and thus ensuring the reliability of the connection. It also reduces the possibility of safety hazards caused by foreign objects snagging on the connector.

[0068] The connector can be a countersunk screw.

[0069] This utility model also discloses a smoke hood; please refer to [link / reference]. Figures 7 to 11 The smoke hood adopts a housing assembly, including a smoke exhaust fan 4 and functional devices. The smoke exhaust fan 4 is used to create negative pressure in the smoke collection chamber b so that external airflow enters the smoke collection chamber b through the air intake 11 and is discharged by the smoke exhaust fan 4. The functional devices are installed in the electrical control chamber a.

[0070] When in use, the exhaust fan 4 is activated, creating negative pressure in the smoke collection chamber b. As a result, fumes and odors are continuously drawn into the smoke collection chamber b through the air intake 11 and then quickly exhausted by the exhaust fan 4. This allows for rapid cleaning of fumes in the kitchen and other spaces, maintaining fresh air and significantly improving indoor air quality. Users are freed from the annoyance of fumes, enhancing the cooking experience. During this process, the partition plate 12 isolates the fumes within the smoke collection chamber b, preventing them from entering the electrical control chamber a and contaminating the functional components. This maintains the long-term cleanliness of the functional components, thus addressing the technical problem of existing range hoods where fumes can easily damage the functional components inside the chamber, leading to increased cleaning and replacement costs.

[0071] Please refer to Figure 1 , Figure 10 as well as Figure 11 The smoke hood of this utility model also includes an air collection box 5, an air outlet 22 communicating with the smoke collection chamber b on the rear cover plate 2, the air collection box 5 connected to the air outlet 22, the smoke exhaust fan 4 located inside the air collection box 5, and the air collection box 5 having an exhaust port for exhausting oil fumes.

[0072] During use, cooking fumes enter the air collection chamber from the fume collection chamber b. During this process, the fumes enter the air collection box 5 through the air outlet 22 on the rear cover plate 2. During installation, the lower edge of the air collection box 5 extends into the air outlet 22 to ensure that all cooking fumes are drawn into the air collection box 5, preventing any leakage. The air collection box 5 can regulate and buffer the chaotic airflow from the fume collection chamber b, allowing the exhaust fan 4 to more efficiently capture and accelerate the cooking fumes, ensuring they are smoothly discharged through the exhaust outlet. This further improves the overall speed and efficiency of fume extraction, reducing the residue and accumulation of cooking fumes in the kitchen.

[0073] The air collection box 5 encloses the exhaust fan 4, providing initial sound insulation and noise reduction. By centrally housing the exhaust fan 4 within the air collection box 5, maintenance personnel can more accurately and conveniently locate the faulty component when the fan malfunctions or when oil buildup inside the air collection box 5 needs cleaning after prolonged use. This allows for operation focused solely on the area within the air collection box 5. Compared to a distributed layout, this design significantly simplifies the maintenance process, reduces maintenance difficulty and costs, and minimizes equipment downtime.

[0074] Please refer to Figures 7-12The smoke hood of this utility model includes a control panel 6 and / or an air curtain assembly 7 and / or an air quality detection module 8 and / or a lighting assembly 9. The control panel 6 is installed on the front side of the housing 1, and the electronic control board on it is placed in the electronic control cavity a. The front cover plate 3 is provided with an air curtain inlet 34 corresponding to the air curtain assembly 7 and / or a detection hole 35 corresponding to the air quality detection module 8, and / or the bottom plate 13 of the housing 1 is provided with an air curtain outlet 131 corresponding to the air curtain assembly 7 and / or a lighting window 132 corresponding to the lighting assembly 9.

[0075] The control panel 6 is installed on the front of the housing 1, making it easily accessible to the user when operating the range hood. Users can easily adjust various functions such as fan speed and mode switching without having to search for the control area, greatly optimizing the human-machine interface and making the cooking process smoother and more efficient. Meanwhile, the electronic control board is placed inside the electronic control cavity a. Thanks to the cavity's robust protective structure, the electronic control board operates stably without external interference, and its layout with the control area ensures it does not interfere with each other.

[0076] The air curtain assembly 7, in conjunction with the air curtain inlet 34 on the front cover 3 and the air curtain outlet 131 on the bottom plate 13 of the housing 1, blows an air curtain below the range hood during operation. This air curtain effectively blocks the spread of cooking fumes and heat, precisely concentrating them into the smoke collection chamber b. This not only enhances the smoke extraction effect but also prevents fumes from staining the kitchen countertop and walls, reducing the subsequent cleaning burden and maintaining a clean kitchen environment.

[0077] The air quality detection module 8, paired with the corresponding detection port 35, can monitor the air quality in the kitchen in real time, including key indicators such as the concentration of cooking fumes and the level of odor. Based on the detection results, users can adjust the operating mode of the range hood or activate the auxiliary purification function to keep the kitchen air in a relatively good state and protect the health of the cook.

[0078] The lighting components 9 and lighting window 132 provide ample and even light to the cooking area. Even if the overall kitchen lighting is poor, the built-in lighting of the range hood can illuminate the stovetop, allowing users to clearly see the food preparation and cooking progress, improving the accuracy and safety of cooking operations, and reducing operational errors caused by dim lighting.

[0079] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
