[0021] like Figure 1 , Figure 2 , Figure 3 As shown, this embodiment of the utility model provides an internal reinforcement structure for a range hood, including a smoke collection hood back panel 1. The inner side of the smoke collection hood back panel 1 has an inwardly protruding molded section 11. A reinforcing plate 2 covers the inner side of the molded section 1 along the width direction of the smoke collection hood back panel 1. A fixing bracket plate 3 is provided inside the reinforcing plate 2. Both the fixing bracket plate 3 and the reinforcing plate 2 are fixedly connected to the smoke collection hood back panel 1.
[0022] The internal reinforcement structure of the range hood provided in this embodiment addresses the issue of insufficient strength in the opening and closing mechanism mounted on the smoke collection hood back panel 1. It incorporates an inwardly protruding molding 11 in the area where the opening and closing mechanism is installed on the smoke collection hood back panel 1, employing a positive and negative molding design to enhance the local strength of the smoke collection hood back panel 1. Simultaneously, a three-layer reinforcement structure is formed by the smoke collection hood back panel 1, the reinforcing plate 2, and the fixing bracket plate 3: the outer layer is the smoke collection hood back panel 1, the middle layer is the reinforcing plate 2, and the inner layer is the fixing bracket plate 3. This further improves the structural strength of the smoke collection hood back panel 1 and prevents abnormal noises from the opening and closing mechanism.
[0023] To facilitate the installation and positioning of the reinforcing plate 2 and the smoke collection hood back plate 1, such as Figure 3 , Figure 4 As shown, in one embodiment of this utility model, the molding die 11 includes a rectangular convex ridge, and a rectangular first recess 12 is formed in the middle of the convex ridge. Figure 5As shown, the reinforcing plate 2 is rectangular, and a second recess 21 corresponding to the first recess 12 is provided in the middle of the reinforcing plate 2. When installing the reinforcing plate 2, the second recess 21 can be positioned in the first recess 12 to accurately position the reinforcing plate 2. The protruding ribs not only reinforce the smoke hood back plate 1, but also play a positioning role, which can simplify the installation of the above-mentioned reinforcing structure and improve the installation efficiency.
[0024] like Figure 6 As shown, in one embodiment of this utility model, the fixing bracket plate 3 includes a first fixing plate 31 with an inverted U-shaped cross-section. The edge of the first fixing plate 31 bends and extends toward the reinforcing plate 2. At both ends of the first fixing plate 31 along the width direction of the smoke hood back plate 1, there are outwardly extending second fixing plates 32, which are located within the second recess 21. At both ends of the first fixing plate 31 along the length direction of the smoke hood back plate 1, there are outwardly extending third fixing plates 33, which correspond to the protruding ridge and the edge of the reinforcing plate 2.
[0025] like Figure 1 , Figure 3 As shown, in one embodiment of this utility model, the edge of the third fixing plate 33, the edge of the reinforcing plate 2, and the edge of the protruding ridge are connected by a first fixing screw 4. The second fixing plate 32, the second recess 21, and the first recess 12 are connected by a second fixing screw 5. Furthermore, when fixing and installing the reinforcing plate 2, since the first fixing screw 4 is tightened from the outside of the smoke hood back plate 1 inwards, manual support is required during installation, affecting efficiency. To solve the above problem, such as... Figures 3-6 As shown, in one embodiment of this utility model, the inner side of the first recess 12 is provided with an inwardly protruding first buckle 13, and the second recess 21 is provided with a first locking hole 22 corresponding to the first buckle 13. During installation, the protruding ridge acts as a limiting element, and the first buckle 13 engages with the first locking hole 22 for fixation, allowing installers to install quickly. Furthermore, the first locking hole 22 corresponding to the first buckle 13 of the smoke hood back plate 1 is designed inside the fixing bracket plate 3 to prevent oil from seeping out from the hole. Similarly, the inner side of the second recess 21 is provided with an inwardly protruding second buckle 23, and the bend between the second fixing plate 32 and the first fixing plate 31 is provided with a second locking hole 34 corresponding to the second buckle 23. When fixing the fixing bracket plate 3, the second buckle 23 engages with the second locking hole 34 for fixation, allowing installers to install quickly.
[0026] like Figure 1 , Figure 3 , Figure 4 As shown, in one embodiment of the present invention, the protruding ridge is located in the middle of the back plate 1 of the smoke collection hood, and both sides of the protruding ridge are provided with inwardly protruding reinforcing ridges 14.
[0027] like Figure 7 , Figure 8 As shown, in one embodiment of this utility model, the top of the smoke hood back panel 1 is provided with a smoke hood top panel 6. To enhance the structural strength of the smoke hood top panel 6, a reinforcing strip 7 is provided on the side of the smoke hood top panel 6 away from the smoke hood back panel 1. The shape of the reinforcing strip 7 corresponds to the shape of the edge of the smoke hood top panel 6 and is located at the bottom edge of the smoke hood top panel 6. During installation, the reinforcing strip 7 can be fixed with rivets first, which can avoid the installer holding it by hand. Then, the front and top surfaces of the reinforcing strip 7 are welded to the smoke hood top panel 6 to connect the reinforcing strip 7 and the smoke hood top panel 6 together, increasing its structural strength. The reinforcing strip 7 is relatively weak in the middle position. To improve the structural strength of the reinforcing strip 7, a number of reinforcing protrusions 71 are provided at intervals on the surface of the reinforcing strip 7 to form a matrix-like reinforcing structure, which can further increase the strength of the reinforcing strip 7.
[0028] To further enhance the structural strength of the smoke hood top plate 6, an irregular molding is provided on the top side of the smoke hood top plate 6 away from the smoke hood back plate.
[0029] This utility model also provides a range hood, including the aforementioned internal reinforcing structure. Specifically, the range hood includes a smoke collection hood, which is provided with the aforementioned smoke collection hood back plate 1, smoke collection hood top plate 6, as well as necessary components such as smoke collection hood side plates and air box, which are existing technologies and will not be described in detail here.
[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
