Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a range hood housing assembly and a range hood. Background Technology

[0002] Range hoods are widely used household appliances in modern kitchens. Their main function is to use a fan system to generate negative pressure airflow, drawing in cooking fumes, steam, odors, and heat from above the stove and expelling them outdoors, or filtering and circulating them for purification, thus maintaining clean and comfortable kitchen air. In actual use, cooking fumes contain a large number of high-temperature oil mist particles, water vapor, and aerosols. These pollutants are not only harmful to human health but also easily accumulate inside the equipment, causing pollution, corrosion, and even safety hazards.

[0003] To improve ease of use, most range hoods have lighting fixtures on their exterior, typically including a light source (such as an LED module, halogen lamp, or fluorescent tube), a lamp holder, wiring, and a transparent lampshade to protect the light source. The lighting fixtures are generally installed inside the range hood casing, with the light-emitting surface facing outwards, projecting light through apertures on the casing to illuminate the cooktop area.

[0004] However, in existing technologies, lighting components are often directly exposed in the air intake duct or internal cavity of the range hood. When the range hood is running, airflow containing a high concentration of oil mist is drawn into the housing under negative pressure. During this process, some fine oil droplets and volatile grease components diffuse throughout the cavity with the airflow, inevitably adhering to the surface of the lighting components, including the lampshade, lamp housing, and circuit board. Over time, this oil buildup forms a difficult-to-remove film on the lampshade surface, significantly reducing light transmittance and affecting lighting performance. Furthermore, oil seeping into the lamp housing can lead to poor heat dissipation, short circuits, component corrosion, or decreased insulation performance, potentially causing lamp malfunctions or even safety accidents in severe cases. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to provide a range hood housing assembly and range hood that improves the sealing performance of the range hood lighting component and has high resistance to oil stains, water, and moisture.

[0011] Furthermore, the outer casing is provided with a snap-fit ​​portion at the inner periphery of the lamp hole; The lamp assembly is provided with a locking part that engages with the locking part to fix the lamp assembly to the housing.

[0012] Furthermore, this also includes mounting brackets; The mounting bracket is fixedly connected to the two opposite sides of the lamp hole, and the protective cover is provided on the outside of the mounting bracket and is detachably connected to the mounting bracket.

[0013] The protective cover and the mounting bracket are detachably connected by screws. The protective cover has a fixing hole for the screw to pass through. The protective cover has a waterproof boss surrounding the fixing hole. A countersunk hole is formed in the middle of the waterproof boss, and the screw head is located in the countersunk hole.

[0014] Furthermore, the inner periphery of the lamp hole is provided with flanges extending into the housing on opposite sides, and adjacent flanges form a positioning part. The mounting bracket cooperates with the positioning part to achieve positioning and installation.

[0025] Example 1 like Figures 1 to 8 As shown in the figure, a range hood housing assembly of this utility model is suitable for range hood equipment used in household or commercial kitchen environments. It aims to solve the technical problems of the lamp assembly 2 being easily contaminated by oil fumes, short-circuiting due to water ingress, and poor sealing performance in the prior art.

[0026] This embodiment provides a range hood housing assembly, including: a housing 1, a lamp assembly 2, and a protective cover 3; the housing 1 has a lamp hole 4; the lamp assembly 2 is connected to the housing 1, and the light-emitting part of the lamp assembly 2 is exposed outward through the lamp hole 4; the protective cover 3 is fixedly connected to the inside of the housing 1 and covers the periphery of the lamp assembly 2, the opening edge of the protective cover 3 is tightly fitted with the inner surface of the housing 1, and the lamp hole 4 is located within the opening range of the protective cover 3; the protective cover 3 has a wire hole 5 for the cable of the lamp assembly 2 to pass through.

[0027] The outer casing 1, serving as the main supporting structure of the entire assembly, is typically made of corrosion-resistant and high-temperature-resistant materials such as stainless steel, cold-rolled steel sheet, or high-strength engineering plastics. It is manufactured through processes such as stamping, bending, welding, or injection molding, possessing excellent mechanical strength and durability. A lamp hole 4 is provided on the outer casing 1. This lamp hole 4 is a rectangular, circular, elliptical, or polygonal through-hole used to accommodate and expose the light-emitting part of the lamp assembly 2. The edges of the lamp hole 4 are chamfered or polished to prevent sharp edges from scratching operators or damaging other components.

[0028] The lamp assembly 2 is installed inside the housing 1, and the light-emitting part of the lamp assembly 2 protrudes outward from the lamp hole 4 on the housing 1 to achieve effective illumination of the external area. To ensure that the lamp assembly 2 does not malfunction due to vibration, oil fume corrosion, or moisture intrusion during operation, a protective cover 3 is provided on the outside of the lamp assembly 2 in this embodiment. The protective cover 3 is generally box-shaped or dome-shaped, with its opening facing the lamp hole 4, and covers the outside of the lamp assembly 2, so that the lamp hole 4 is located within the opening range of the protective cover 3, forming a closed protective cavity to effectively isolate oil fumes.

[0029] The opening edge of the protective cover 3 fits tightly against the inner periphery of the lamp hole 4 on the outer shell 1. This fit is not only reflected in the precise matching of geometric dimensions, but also in the achievement of airtightness and watertightness through the addition of a sealing structure. Specifically, a sealing ring 6 is provided at the opening edge of the protective cover 3. This sealing ring 6 is made of elastic materials such as silicone, EPDM rubber, or fluororubber, and has excellent temperature resistance, oil resistance, and compression resilience. The sealing ring 6 is located between the protective cover 3 and the outer shell 1. When the protective cover 3 is installed in place, the sealing ring 6 is compressed between the edge of the protective cover 3 and the inner wall of the lamp hole 4, forming a waterproof and oil-proof sealing barrier, effectively preventing oil from penetrating the interior of the protective cover 3.

[0030] To enhance oil and water resistance, the opening edge of the protective cover 3 extends radially outward to form a waterproof platform 7. This platform 7 has an annular flange structure, and its width and height are designed according to actual sealing requirements, typically ranging from 3 to 8 millimeters. A sealing ring 6 is positioned on the end face of the platform 7 facing the outer casing 1, i.e., the sealing ring 6 is clamped between the platform 7 and the edge of the lamp hole 4 on the outer casing 1. When the protective cover 3 is pressed tightly in place, any liquid flowing along the inner surface of the outer casing 1 must pass over the sealing ring 6 to enter the interior of the protective cover 3, thereby significantly improving the overall waterproof rating of the component and achieving a higher protection standard.

[0031] Crucially, the waterproof platform 7 has an annular sealing groove on its end face facing the outer casing 1. This sealing groove is a recessed structure formed around the bottom surface of the waterproof platform 7, and its cross-sectional shape can be rectangular, semi-circular, or trapezoidal, extending continuously around the entire circumference of the waterproof platform 7. The dimensions of the sealing groove match the installed sealing ring 6, ensuring that the sealing ring 6 can be securely embedded within it without displacement.

[0032] Considering that the lamp assembly 2 requires external power during operation, its cable must be led out from inside the protective cover 3 and connected to an external power source. Therefore, the protective cover 3 is provided with a cable passage hole 5, which is a small hole penetrating the side wall or bottom wall of the protective cover 3 for the cable of the lamp assembly 2 to pass through. However, the presence of the cable passage hole 5 may become a new leakage channel; therefore, in this embodiment, a sealing element 8 is added inside the cable passage hole 5. This sealing element 8 is integrally molded from a flexible waterproof material (such as TPE thermoplastic elastomer or silicone), and its central part has a cable hole 15 for the cable to pass through.

[0033] The seal 8 is installed inside the cable passage hole 5, and its outer wall is press-fitted with the inner wall of the cable passage hole 5 or fixed by adhesive to ensure that the seal 8 itself will not loosen or fall off. When the cable passes through the cable hole 15 of the seal 8, the inner wall of the cable hole 15 tightly hugs the cable sheath due to the elasticity of the material, forming a sealing barrier to effectively prevent moisture or oil fumes from entering through the cable channel.

[0034] Further optimized, the seal 8 comprises a composite structure consisting of a limiting part 81, a groove part 82, and a guide part 83 connected in sequence. Both the limiting part 81 and the groove part 82 are annular; the guide part 83 is conical, with its outer diameter gradually decreasing away from the groove part 82. The groove part 82 passes through the wire hole 5. The maximum diameter of the guide part 83 and the diameter of the limiting part 81 are both larger than the diameter of the wire hole 5, providing axial limiting and preventing the seal 8 from completely sinking into the wire hole 5. The groove part 82 is located in the middle, with its outer diameter slightly larger than the wire hole 5. During installation, pressure is applied to deform it and allow it to enter the wire hole 5. Afterward, it recovers through material elasticity and fits tightly against the wire hole 5, achieving a circumferential seal. The guide part 83 is conical, with its outer diameter gradually decreasing away from the groove part 82, facilitating the smooth insertion of the seal 8 into the wire hole 5, reducing assembly difficulty, and protecting the seal 8 from damage. This design not only improves sealing reliability but also enhances assembly efficiency and maintainability.

[0035] Regarding the fixing method of the lamp assembly 2, this embodiment adopts a snap-fit ​​structure to achieve quick installation and disassembly. Specifically, the outer shell 1 is provided with a snap-fit ​​part 9 at the inner periphery of the lamp hole 4. The snap-fit ​​part 9 can be a plurality of notches, grooves, bosses or elastic claws evenly distributed along the edge of the lamp hole 4. In this embodiment, the snap-fit ​​part 9 is preferably a set of symmetrically arranged notches, each notch is U-shaped or semi-circular, with a depth of 1~3 mm, for cooperating with the snap-fit ​​part 10 on the lamp assembly 2.

[0036] The lamp assembly 2 is provided with a locking part 10 that engages with the locking part 9. This locking part 10 is composed of one or more elastic spring pieces 14. The spring piece 14 has a U-shaped structure and is stamped from elastic metal materials such as spring steel or phosphor bronze, possessing good elasticity and fatigue life. The two free ends of the spring piece 14 are provided with outwardly protruding locking parts 10 (such as protrusions, barbs, or beveled wedge structures), while the middle part of the spring piece 14 is fixedly connected to the metal base of the lamp assembly 2 by fasteners (such as screws or bolts). When the lamp assembly 2 is inserted into the lamp hole 4, the spring piece 14 is compressed and contracts, and the locking part 10 slides past the edge of the lamp hole 4. Once it reaches the locking part 9, the spring piece 14 returns to its original shape, and the locking part 10 is embedded in the locking part 9, achieving automatic locking. This structure allows for installation without additional tools, and disassembly is achieved simply by pressing the spring piece 14 to disengage it from the locking part 9, greatly facilitating maintenance and replacement.

[0037] To further improve the installation stability and positioning accuracy of the protective cover 3, an installation bracket 11 is added in this embodiment.

[0038] The mounting bracket 11 is fixedly connected to the two opposite sides of the lamp hole 4, and the protective cover 3 is placed on the outside of the mounting bracket 11 and is detachably connected to the mounting bracket 11.

[0039] Specifically, the protective cover 3 and the mounting bracket 11 are detachably connected using screws. A through hole 17 is provided at the bottom of the protective cover 3 for the screw to pass through, and the axis of the through hole 17 is approximately perpendicular to the bottom of the protective cover 3. A corresponding through hole is provided on the mounting bracket 11. After the screw passes through this through hole, it is screwed into the through hole 17 on the protective cover 3, thereby firmly fixing the protective cover 3 to the mounting bracket 11.

[0040] More specifically, the protective cover 3 has a waterproof boss 18 around the fixing hole 17, and a countersunk hole is formed in the middle of the waterproof boss 18, with the screw head located in the countersunk hole.

[0041] To prevent external water droplets or cleaning liquids from seeping into the interior of the protective cover 3 along the screw gaps, a waterproof protrusion 18 is provided on the outer surface of the protective cover 3, surrounding the fixing hole 17. This waterproof protrusion 18 is an annular or frustoconical structure protruding outward from the outer surface of the protective cover 3, with a countersunk hole formed in its center. The fixing hole 17 is located at the bottom center of this countersunk hole. After the screw is installed, its head is completely contained within the countersunk hole and does not protrude from the top surface of the waterproof protrusion 18.

[0042] This structural design ensures that liquids such as rainwater and cleaning water must pass over the outer edge of the waterproof protrusion 18 before contacting the screw head when flowing over the surface of the protective cover 3. This significantly increases the resistance to liquid entry and effectively improves the waterproof rating of the connection point. Simultaneously, the screw head is concealed within the countersunk hole, avoiding the rough appearance of exposed fasteners and making the overall structure more aesthetically pleasing and streamlined.

[0043] The mounting bracket 11 is made of stamped or bent metal sheet, and has an overall U-shaped structure with two parallel side arms and a crossbeam connecting the two arms. The two ends of the mounting bracket 11 are firmly connected to the inner wall of the outer casing 1 by welding, riveting, or screwing, forming a stable support frame. The protective cover 3 is fixedly connected to the crossbeam of the mounting bracket 11 by a detachable connection method (such as screws, clips, or quick-release clamps). For example, a threaded hole is provided at the top of the protective cover 3, and a through hole is provided at the corresponding position on the crossbeam of the mounting bracket 11. A screw is screwed through the through hole and into the threaded hole, thereby firmly fixing the protective cover 3 inside the outer casing 1.

[0044] In addition, in order to ensure that the mounting bracket 11 is accurately positioned during welding or fixing and to avoid displacement affecting the alignment of the protective cover 3 and the lamp hole 4, the outer shell 1 is also provided with a positioning part 12 near the inner periphery of the lamp hole 4.

[0045] Specifically, the inner periphery of the lamp hole 4 has corresponding flange groups extending into the housing 1 on opposite sides. Adjacent flange groups form positioning parts 12, and the mounting bracket 11 cooperates with the positioning parts 12 to achieve positioning. The positioning part 12 is one or more protrusion structures, preferably a positioning unit composed of four protrusions, which are symmetrically distributed in pairs on both sides of the lamp hole 4. Each end of the mounting bracket 11 is engaged between two protrusions to achieve quick positioning. For example, each positioning part 12 consists of two cylindrical protrusions and two square protrusions, corresponding to one end of the mounting bracket 11, which restricts the lateral movement of the bracket.

[0046] To further enhance the structural strength of the protective cover 3 and prevent it from cracking due to thermal deformation or external impact during long-term use, this embodiment provides multiple reinforcing ribs 13 on the inner wall of the protective cover 3. These reinforcing ribs 13 are integrally injection molded with the protective cover 3 body and are distributed in the transition area between the bottom wall and the side wall of the protective cover 3, i.e., the stress concentration area. The cross-sectional shape of the reinforcing ribs 13 can be triangular, trapezoidal, or semi-circular, with a height of 1-2 mm and a spacing of 10-20 mm, arranged radially, in a grid pattern, or in a ring. They not only improve the overall rigidity and bending resistance of the protective cover 3, but also play a role in heat dissipation and heat conduction, helping to evenly dissipate the heat generated by the lamp assembly 2 and extend the lamp's lifespan.

[0047] In addition, the reinforcing rib 13 is U-shaped, and its curvature matches the shape of the inner wall of the protective cover 3. Multiple reinforcing ribs 13 are distributed at intervals along the length of the protective cover 3. The reinforcing rib 13 is composed of a rib-like structure integrally injection molded with the protective cover 3 body, which is used to improve the overall rigidity and deformation resistance of the protective cover 3 and prevent it from warping or cracking under high temperature or external force.

[0048] At least one reinforcing rib 13 has a positioning rib. The positioning rib is a limiting space formed by the internal recess of the U-shaped reinforcing rib 13. When the mounting bracket 11 is assembled into the housing 1, one end of it abuts against the end face of the positioning rib (i.e., the reinforcing rib 13), so as to achieve precise positioning of the mounting bracket 11.

[0049] Through this structural design, during the assembly of the protective cover 3 and the mounting bracket 11, the positioning ribs can guide and restrict the position of the mounting bracket 11, preventing the mounting bracket 11 from shifting or misaligning, and ensuring that the wire hole 5, fixing hole and other structures on the protective cover 3 are accurately aligned with the mounting bracket 11 and other components, thereby improving assembly efficiency and consistency.

[0050] In practical applications, considering that range hoods typically require uniform lighting on both sides of the cooktop, this embodiment also incorporates a dual-lamp configuration. Specifically, a lamp hole 4 is located on each of the left and right sides of the outer casing 1, with each lamp hole 4 housing an independent lamp assembly 2 and a protective cover 3. The two lighting units can be controlled independently or operate synchronously, providing a wider, shadow-free lighting range. The lamp assemblies 2 on both sides can be connected to a control switch via a shared power cord or independent wiring to meet the needs of different users.

[0051] In addition to the specific structure described above, this utility model can be modified and expanded in various ways. For example, the sealing ring 6 can be designed as a double-lip structure to increase the sealing layer; the lamp assembly 2 can integrate an intelligent sensing module to realize the function of automatically turning on the light when a person approaches. The entire housing assembly can be adapted to different models of range hoods, including top-mounted, side-mounted, and downdraft types, and has wide applicability and market prospects.

[0052] In summary, the range hood housing assembly described in this embodiment, through its scientific and reasonable structural design, integrates multiple sealing, elastic snap-fit, bracket assistance, and reinforcing rib 13, effectively solving the problems of poor sealing, cumbersome installation, and insufficient strength in traditional range hood lighting systems. It significantly improves the product's safety, reliability, and user experience, and has high practical value and promotional significance.
