[0002] With the continuous upgrading of modern kitchen design concepts, the functional and aesthetic requirements of range hoods, as core electrical appliances in the kitchen environment, are increasing. However, the existing range hood casing structure still has many technical defects in practical applications and urgently needs improvement to meet higher performance and reliability requirements.

[0003] Currently, most range hood casing components are made from low-cost materials such as cold-rolled steel sheets or galvanized sheets with a thickness of 0.6-0.8mm, formed by single-layer stamping. Due to the limited strength of the materials themselves, and the increasingly compact design of the front section (top or upper front area) of the casing component (to match the narrow depth requirements of cabinets), the stress-bearing area of ​​the front section is significantly reduced. During transportation or drop tests, the front section of the casing component is highly susceptible to dents and deformation due to external impacts, seriously affecting the product's appearance and lifespan. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a novel range hood shell that can improve the overall strength and stability of the shell components by optimizing the connection method and structural design without increasing the material thickness.

The above schematic diagram is only for illustrating the structural relationships related to the inventive point and is not intended as an actual scale of a product.

[0022] Example 1 like Figures 1 to 7 As shown in the figure, a range hood housing according to an embodiment of the present invention includes a front cover plate 9, a front panel 10, a decorative glass mounting panel 11, a switch assembly, and a reinforcing plate. This range hood housing serves as the main load-bearing component of the external structure of the range hood, integrating and fixing the operation control module, improving the overall structural rigidity, and achieving an aesthetically pleasing appearance.

[0023] The front cover 9 is located at the top of the front of the range hood. Its front edge is firmly connected to the top edge of the header plate 10 through continuous resistance spot welding, forming a seamless outer surface contour, avoiding gaps for oil accumulation, and facilitating cleaning and maintenance. The front cover 9 can be made of SUS304 stainless steel cold-rolled sheet material, which is stamped by multi-station progressive dies and then brushed on the surface, giving it excellent corrosion resistance and a high-end visual texture.

[0024] The front panel 10 is located directly below the cover plate 9, forming one of the main supporting frames in the center of the front of the range hood. The front panel 10 can be made of SPCC cold-rolled carbon structural steel or the same material as the cover plate 9, and undergoes stamping, bending, and electrophoretic coating treatment, giving it good mechanical strength and rust resistance. A rectangular notch is provided in the middle of the front panel 10 along the horizontal direction. This notch extends through the front and rear of the front panel 10, and its specific size can be adjusted according to the shape of different models of switch components to ensure that the switch components can be fully embedded and the operating interface is exposed.

[0025] On the left and right sides of the top panel 10, a decorative glass mounting panel (side decorative glass mounting panel 11 and right side decorative glass mounting panel 11) is fastened to the bottom edge with self-tapping screws. Both decorative glass mounting panels 11 are fixedly connected to the corresponding bottom edge of the top panel 10 by their front edges, and are located within the vertical projection range of the cover plate 9, below the cover plate 9. The decorative glass mounting panels 11 can be made of galvanized steel sheet or the same material as the cover plate 9, and are used to support and fix the decorative glass panel (usually 6 mm thick tempered transparent glass). The decorative glass panel is installed on its surface using silicone sealant or a snap-on structure, thus forming the decorative area at the lower front of the range hood, enhancing the product's modern and technological feel.

[0026] The rectangular notch on the front panel 10 and the space between the two decorative glass mounting panels 11 together form an operating assembly area for installing the switch assembly. The switch assembly is an electronic touch control module or a mechanical button control panel, including operating elements such as a fan start / stop button, a fan speed adjustment button, a light switch, and a delayed shutdown function button. The switch assembly has an overall elongated structure, arranged horizontally within the notch of the front panel 10, with its front end face basically flush with the front surface of the front panel 10 to facilitate user touch operation. The switch assembly is connected to the reinforcing plate at both the left and right ends, achieving a stable and reliable mechanical fixation.

[0027] Reinforcing plates are located at the left and right edges of the notch in the forehead plate 10, with one left and one right reinforcing plate respectively installed at the left and right ends of the switch assembly. Each reinforcing plate is physically connected to the switch assembly, the front cover plate 9, the forehead plate 10, and the corresponding decorative glass mounting panel 11, forming a four-point linkage support system. This multi-point connection structure significantly improves the overall rigidity of the local structure, effectively preventing plastic deformation, dents, or cracks in the forehead plate 10 caused by frequent pressing of the switch assembly, thus extending the product's service life.

[0028] The reinforcing plate comprises five functional components: the main connecting plate 1, the front cover connecting part 2, the top plate connecting part 3, the decorative glass mounting panel connecting part 4, and the switch assembly connecting part 5. The main connecting plate 1 is a vertically arranged flat plate structure located within the vertical gap between the front cover 9 and the decorative glass mounting panel 11, and is not exposed externally, being concealed within the overall internal structure of the machine. The main connecting plate 1 is made of SPCC material, possessing good solderability and formability.

[0029] The faceplate connecting part 2 is located at the top of the main connecting plate 1. One edge of the faceplate connecting part 2 is perpendicularly connected to the upper edge of the main connecting plate 1 through a single stamping and bending process, while the other side extends and connects to one edge of the switch assembly connecting part 5. The faceplate connecting part 2 has an overall L-shaped structure. The free end abuts against the lower surface of the faceplate 9 and is fastened by screws passing through preset holes, thereby anchoring the upper part of the reinforcing plate to the faceplate 9 structure and ensuring effective transmission of longitudinal load.

[0030] The switch assembly connecting part 5 is located at the far end of the faceplate connecting part 2, that is, on the side away from the main board 1. It is formed by bending downward from the side of the faceplate connecting part 2 and then extending horizontally outward. The switch assembly connecting part 5 has a flat strip structure, and its end is provided with at least one circular mounting hole 8 for alignment and mating with the pre-set threaded connection hole on the left or right end of the switch assembly. During assembly, screws are passed through the connection hole at the end of the switch assembly and the mounting hole 8 on the reinforcing plate in sequence to complete the mechanical fastening connection, ensuring that the switch assembly will not experience lateral displacement or loosening.

[0031] The forehead plate connecting part 3 is located on the front side of the connecting plate main board 1 and the front cover connecting part 2. This can be achieved through two implementation schemes: the first scheme involves bending the front edge of the front cover connecting part 2 downwards vertically to form the forehead plate connecting part 3; the second scheme involves bending the front edge of the connecting plate main board 1 inwards towards the fuselage, i.e., backwards, to form the forehead plate connecting part 3. Regardless of the form used, the forehead plate connecting part 3 is ultimately tightly fitted to the rear side of the forehead plate 10 and fixedly connected using resistance spot welding, creating a stable surface contact support relationship between the reinforcing plate and the forehead plate 10, further enhancing the overall structural integrity and impact resistance.

[0032] The decorative glass mounting panel connecting part 4 is located at the bottom end of the main connecting plate 1, and is formed by horizontally bending outward from the lower edge of the main connecting plate 1, creating a horizontal support structure. This decorative glass mounting panel connecting part 4 is completely attached to the lower surface of the left or right decorative glass mounting panel 11 and is fixedly connected by welding or riveting. In the installed state, the decorative glass mounting panel connecting part 4 abuts against the lower bottom edge of the notch on both sides of the header plate 10, providing support and preventing the decorative glass mounting panel 11 from sinking, shaking, or fatigue-breaking due to its own weight or external vibration.

[0033] The main connecting plate 1 and the connecting portion 2 of the cover plate are arranged perpendicularly to each other, with an included angle of 90 degrees, forming a stable right-angle support configuration. At least one reinforcing protrusion 7 is provided in the inner corner region of this connecting portion. The reinforcing protrusion 7 is a locally raised structure formed on the metal sheet by a special stamping die, with a circular or trapezoidal cross-section. This reinforcing protrusion 7 forms a raised structure between the lower surface of the connecting portion 2 of the cover plate and the lower surface of the main connecting plate 1, and a corresponding recessed area on the opposite side. This bidirectional undulating structure significantly improves the bending stiffness, torsional performance, and fatigue life of the connecting area, making it particularly suitable for applications subjected to repeated dynamic loads.

[0034] The edge of the faceplate connecting portion 2 near the switch assembly connecting portion 5 is further bent downward to form a connecting plate 6. This connecting plate 6 serves as a transition section connecting the faceplate connecting portion 2 and the switch assembly connecting portion 5. The presence of the connecting plate 6 makes the force transmission path smoother and the stress distribution more uniform, avoiding metal fatigue cracking caused by stress concentration. The switch assembly connecting portion 5 is formed by continuing to bend horizontally outward from the bottom end of the connecting plate 6, and finally abuts against the lower top edge of the notch on both sides of the forehead plate 10, forming multi-point support, which helps to disperse the operating reaction force from the switch assembly.

[0035] The number of reinforcing shaped plates 7 can be set to one, two, or more as needed, preferably two, symmetrically distributed on both sides of the junction area between the main plate 1 and the cover plate 2. Furthermore, in other expandable embodiments, reinforcing ribs, flanged structures, or locally thickened plates can be used to replace the reinforcing shaped plates 7 to meet the structural strength requirements of different product models.

[0036] In terms of manufacturing process, the reinforcing plate is made using a one-piece molding technology. This means that from a single raw material, through multiple secondary die-pressing processes, all structural features, including the main connecting plate 1, cover plate connecting part 2, forehead plate connecting part 3, decorative glass mounting panel connecting part 4, switch assembly connecting part 5, as well as the reinforcing forming part 7 and mounting holes 8, are formed in one continuous process. This one-piece molding process not only ensures the consistency of geometric precision between components but also reduces subsequent assembly steps, lowers production costs, and improves product quality stability.

[0037] Mounting holes 8 are provided on the end plane of the switch assembly connecting part 5. Two threaded holes are provided on the left and right ends of the switch assembly respectively. During assembly, screws are passed through the connecting holes and mounting holes 8 in sequence and tightened to achieve a reliable connection between the switch assembly and the reinforcing plate. In other feasible implementations, snap-fit ​​connections, riveting connections, or adhesive-assisted fixing methods can also be used to improve assembly efficiency and seismic performance.

[0038] The decorative glass mounting panel connecting part 4 is formed by bending outward from the bottom end of the main connecting plate 1 at a bending angle of 90 degrees, ensuring sufficient contact area with the lower surface of the decorative glass mounting panel 11. After installation, the decorative glass mounting panel connecting part 4 abuts against the lower bottom edge of the notch on both sides of the front panel 10, forming a double support structure that both connects the decorative glass mounting panel 11 and supports the front panel 10, enhancing the stability of the entire front structure.

[0039] The reinforced forming 7 creates a distinct raised structure between the lower surface of the cover plate connecting part 2 and the lower surface of the connecting plate main plate 1. This raised structure protrudes towards the internal space of the range hood, while a corresponding recessed area is formed on the opposite outer side. This structure not only effectively suppresses the buckling deformation of the thin plate under stress, but also plays a certain role in sound insulation and vibration reduction, reducing the structural resonance noise during fan operation.

[0040] Example 2 A specific embodiment of a range hood includes the range hood housing as described in Embodiment 1 above. The range hood also includes a fan system, a smoke collection chamber, a smoke exhaust duct interface, a lighting device, a control system, and a suspension mounting mechanism. The fan system is installed inside the smoke collection chamber and generates negative pressure by driving a centrifugal impeller at high speed through a motor, drawing in cooking fumes and exhausting them outdoors through the smoke exhaust duct. The lighting device is located below the front cover 9, providing illumination to the stove area. The control system is electrically connected to a switch assembly, receiving user commands and controlling the fan speed and lighting status. The entire range hood is suspended from the kitchen wall via a back panel structure for stable installation. This range hood is suitable for the efficient smoke extraction needs of Chinese stir-frying environments and has the advantages of robust structure, convenient operation, easy cleaning, and long service life.
