The first side panel 2 and the second side panel 3 are hexagons with unequal side lengths, respectively, and the second side panel 3 and the second side panel 2 are symmetrically provided on both sides of the top rear panel 1.

[0038] The range hood casing of the embodiment of the utility model is reasonably disassembled, and three plates are bent and connected to form a shell cavity, one of which is bent to form a top rear panel 1, and the other two plates form two side panels respectively. The first side panel 2 of the two side panels is located on the first side of the top rear panel 1. In a specific implementation, the first side panel 2 can be located on the left side of the top rear panel 1, and the second side panel 3 is located on the second side of the top rear panel 1. In a specific implementation, the second side panel 3 can be located on the right side of the top rear panel 1. By reasonably disassembling the complex casing, the mold structure is simplified and the material utilization rate is improved.

[0039] In some implementations, the first side panel 2 is riveted to the top panel 11 and welded to the rear panel 12. The second side panel 3 is riveted to the top panel 11 and welded to the rear panel 12. The first and second side panels 2, 3 are each connected to the top panel 11 via rivets to ensure the appearance of the top surface. The first and second side panels 2, 3 are each welded to the rear panel 12, for example, by argon arc welding.

[0040] In some embodiments, see Figure 2 and Figure 3 The first side panel 2 and the second side panel 3 are riveted to the top panel 11 inside the shell cavity, and the second side panel 3 is riveted to the top panel 11 inside the shell cavity. The first side panel 2 and the second side panel 3 are riveted to the top panel 11 inside the shell cavity, preventing the rivets from being exposed on the surface of the shell, ensuring a neat appearance of the top.

[0041] In the exemplary embodiment, see Figures 2 to 6 The first side panel 2 and the second side panel 3 each have a first rivet portion 4 formed by folding, and the first side and the second side of the top panel 11 each have a second rivet portion 111 formed by folding.

In a specific implementation, the first connecting folded portion 24 and the front panel 13 may be spot-welded, which simplifies operation, increases speed, and improves productivity.

[0047] In some embodiments, see Figure 2 and Figure 3 The second side panel 3 includes a second side edge 32 and a second bottom edge 33 that are interconnected. The second side edge 32 is tilted backward from top to bottom, and the second bottom edge 33 is opposite the rear bottom panel 15. The folding structure of the second side panel 3 includes a second side bottom panel 35 formed by folding one side of the second side edge 32 inward, and a second extension portion 36 formed by folding the rear end of the second side bottom panel 35 backward. The second extension portion 36 is located inside the second bottom edge 33, and the second connecting folding portion 34 is connected to the front panel 13. The second side bottom panel 35 is connected to the front bottom panel 14, and the second extension 36 is connected to the second bottom edge 33 and the rear bottom panel 15 respectively.
