[0057] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0058] like Figures 1 to 9 As shown, this embodiment provides a range hood housing that simplifies the assembly process, improves assembly efficiency, and ensures the appearance quality after assembly. The range hood housing includes a main body shell 1 and a sealing plate 2.

[0059] Among them, see Figure 1 , Figure 2 and Figure 3 The main shell 1 is an integrally molded component, which includes a main plate 11 and a first side plate 12 and a second side plate 13 respectively disposed at both ends of the main plate 11. The first side plate 12 and the second side plate 13 each include a cantilever plate 121 that is set at an angle to the main plate 11 and extends out of the main plate 11. The three adjacent sides of the sealing plate 2 are respectively spliced ​​and fixed to the cantilever plate 121 of the first side plate 12, the cantilever plate 121 of the main plate 11 and the second side plate 13.

[0060] The splicing and fixing methods here include, but are not limited to, welding, bonding, bolting, riveting, etc., as long as they can meet the fixing requirements between components.

[0061] The range hood housing provided in this embodiment has a top opening formed between the cantilever plates 121 of the first side plate 12, the main body plate 11, and the cantilever plates 121 of the second side plate 13. The sealing plate 2 can seal this top opening. Since the main body shell 1 is a one-piece molded component, when assembling the main body shell 1 and the sealing plate 2, it is only necessary to connect and fix the three sides of the sealing plate 2 to the first side plate 12, the main body plate 11, and the second side plate 13 respectively, without assembling the main body plate 11 with the first side plate 12 and the second side plate 13. This reduces the number of parts in the range hood housing, thus simplifying the assembly process and improving the assembly efficiency and production efficiency of the range hood housing. At the same time, the one-piece molding process of the main body shell 1 can reduce the number of splicing seams, ensuring the aesthetics of the range hood housing while reducing assembly difficulty and manufacturing costs.

[0062] Furthermore, the cantilever plate 121 forms an angle with the main body plate 11 and extends beyond the main body plate 11. After the sealing plate 2 is assembled with the main body shell 1, refer to... Figure 1 and Figure 4 The main body plate 11 is located at the rear of the stove area, and the sealing plate 2 is located above the stove area (referring to the normal orientation of the range hood casing during use). That is, the range hood casing has an upper and lower smoke collection chamber structure, combining side suction and top suction effects. Due to process limitations, this structure with upper and lower smoke collection chambers cannot typically be integrally stretched to form the entire range hood casing structure. Therefore, this application uses an integral molding process for the main body shell 1, and then connects and fixes the sealing plate 2 to the main body shell 1. Compared to the existing multi-plate splicing technology, this reduces the number of parts in the range hood casing while meeting process requirements, thus simplifying the assembly process and improving the assembly and production efficiency of the range hood casing.

[0063] See Figure 3 , Figure 4 and Figure 5 The sealing plate 2 has three sides defined as a first side 21, a second side 22, and a third side 23. The cantilever plate 121 has a first connecting edge 1211 and a second connecting edge 1212 arranged opposite to each other. The first connecting edge 1211 is closer to the main plate 11 than the second connecting edge 1212. The first side 21 and the third side 23 are fixedly connected to the first connecting edge 1211 of the corresponding cantilever plate 121, and the second side 22 is fixedly connected to the main plate 11. That is, the first side 21 of the sealing plate 2 is spliced ​​and fixed to the first connecting edge 1211 of the cantilever plate 121 of the first side plate 12, the second side 22 of the sealing plate 2 is spliced ​​and fixed to the main plate 11, and the third side 23 of the sealing plate 2 is spliced ​​and fixed to the first connecting edge 1211 of the cantilever plate 121 of the second side plate 13, thereby achieving the connection and fixation between the sealing plate 2 and the main shell 1.

[0064] Specifically, in this embodiment, the first side 21 and the third side 23 are welded to the first connecting edge 1211 of the corresponding cantilever plate 121, and the second side 22 is welded to the main plate 11. Since the first side plate 12, the second side plate 13 and the main plate 11 are integrally formed, during assembly, it is only necessary to weld the first side 21 to the first connecting edge 1211 of the first side plate 12, weld the second side 22 to the top side of the main plate 11, and weld the third side 23 to the first connecting edge 1211 of the second side plate 13, without needing to weld the main plate 11 to the first side plate 12 and the second side plate 13. This effectively reduces the amount of welding work, improves assembly efficiency, and, by shortening the welding length, it is easier to ensure the appearance quality of the weld and reduce the assembly difficulty.

[0065] Alternatively, welding can be performed using laser welding, spot welding, argon arc welding, etc., and the appropriate method can be selected based on actual needs. No specific restrictions are placed on the specific form of welding here.

[0066] Optionally, a first positioning structure is provided on both the first side 21 and the third side 23, and a second positioning structure is provided on the first connecting edge 1211. The second positioning structure can cooperate with the corresponding first positioning structure to position the first side 21 and the third side 23 at their fixed positions relative to the corresponding first connecting edge 1211. During the assembly of the main body shell 1 and the sealing plate 2, the cooperation between the first positioning structure and the second positioning structure can position the sealing plate 2 on the main body shell 1, facilitating fixing operations (such as welding operations) and ensuring the assembly accuracy of the sealing plate 2 and the main body shell 1.

[0067] See Figure 6 and Figure 7 The first positioning structure includes a first stepped groove 2101, and the first end of the first side 21 and the first end of the third side 23 are both provided with the first stepped groove 2101. The second positioning structure includes a second stepped groove 12101 provided at the first end of the first connecting edge 1211, and the second stepped groove 12101 is engaged with the corresponding first stepped groove 2101. Figure 7 As shown, after the first stepped groove 2101 and the second stepped groove 12101 are interlocked, they can restrict the movement of the sealing plate 2 relative to the main shell 1 in the left-right direction and also restrict the movement of the sealing plate 2 relative to the main shell 1 in the up-down direction. This ensures the positioning accuracy of the sealing plate 2 and the main shell 1, facilitating subsequent fixing operations. For example, during welding operations, after the first stepped groove 2101 and the second stepped groove 12101 are interlocked, the first side 21 can be aligned with the first connecting edge 1211, making the welding operation easier, ensuring the uniformity of the weld, reducing welding defects (such as porosity, slag inclusions, and lack of fusion), and making the welding process more stable.

[0068] See Figure 5 and Figure 8The first positioning structure includes a third stepped groove 2102. The second end of both the first side 21 and the second end of the third side 23 are provided with third stepped grooves 2102. The second positioning structure includes a fourth stepped groove 12102 located at the second end of the first connecting edge 1211. The fourth stepped groove 12102 engages with the corresponding third stepped groove 2102. During assembly, simply engaging the third stepped groove 2102 with the fourth stepped groove 12102 ensures a tight fit between the first side 21 and the first connecting edge 1211 of the first side plate 12, and a tight fit between the third side 23 and the first connecting edge 1211 of the second side plate 13. This also restricts the position of the sealing plate 2 relative to the main shell 1 in the front-back direction, facilitating fastening operations (such as welding) and further ensuring the assembly accuracy of the sealing plate 2 and the main shell 1.

[0069] Optionally, see Figure 5 A second flange 221 is provided at the second side 22. The second flange 221 bends towards the main body plate 11, and a stepped structure is formed at the connection between the second flange 221 and the second side 22. During assembly, the second flange 221 is inserted downwards to fit against the inner surface of the main body plate 11. The aforementioned stepped structure overlaps the top side of the main body plate 11, and then the second side 22 is connected to the main body plate 11 by welding. The provision of the second flange 221 can, on the one hand, increase the welding contact area between the second side 22 and the main body plate 11, thereby improving the connection strength. On the other hand, it can also play a positioning role in fixing the second side 22 and the main body plate 11, making subsequent welding operations easier, reducing welding defects, and improving welding quality.

[0070] See Figure 5 and Figure 6 Both the first side 21 and the third side 23 include a connected first arc-shaped edge 211 and a first straight edge 212. The first connecting edge 1211 includes a connected second arc-shaped edge 12111 and a second straight edge 12112. The second arc-shaped edge 12111 is fixedly connected to the first arc-shaped edge 211, and the second straight edge 12112 is fixedly connected to the first straight edge 212. The arrangement of the first arc-shaped edge 211 and the second arc-shaped edge 12111 ensures that after the sealing plate 2 is connected and fixed to the main shell 1, the side of the main shell 1 facing the user does not have sharp corners, resulting in a more aesthetically pleasing appearance and reducing the likelihood of hard-to-clean corners, making it easier for the user to clean later.

[0071] See Figure 6The first side plate 12 and the second side plate 13 both include a side plate body 122 arranged at an included angle and the aforementioned cantilever plate body 121. The side plate body 122 is integrally formed with the main body plate 11, and the connection between the cantilever plate body 121 and the side plate body 122 is smoothly transitioned to form the aforementioned second arc-shaped edge 12111. In this embodiment, the cantilever plate body 121 extends forward relative to the main body plate 11 (referring to the orientation of the range hood casing during normal use), so that the sealing plate 2 is located above the stove area, which can better collect smoke and improve the smoke exhaust effect of the range hood.

[0072] Furthermore, the side panel 122 includes a first panel 1221 and a second panel 1222 arranged at an angle. The first panel 1221 is connected to the main panel 11, and the second panel 1222 is bent toward the inside of the main panel 11 relative to the first panel 1221, which can increase the structural strength of the side panel 122 itself.

[0073] See Figure 5 and Figure 6 Both the first side 21 and the third side 23 have a first flange 214 at the end away from the second side 22. The first flange 214 is spliced ​​and fixed to the end of the cantilever plate 121 away from the main body plate 11, and the splice point between the first flange 214 and the cantilever plate 121 is located on the side of the main body shell 1. That is, one end of the first flange 214 extends towards the cantilever plate 121 and splices with the cantilever plate 121. This arrangement allows the seam 2140 between the first side 21 and the third side 23 and the cantilever plate 121 to remain on the side (e.g., Figure 6 and Figure 8 As shown in the figure, this ensures that the seam 2140 is not visible on the front of the range hood casing, thus improving the overall aesthetics of the range hood casing.

[0074] In this embodiment, as Figure 5 and Figure 8 As shown, the first flange 214 and the first straight edge 212 of the first side 21 (third side 23) form the aforementioned third stepped groove 2102, and the fourth stepped groove 12102 is machined at the end of the cantilever plate 121. The first flange 214 is welded to the end of the cantilever plate 121, and the connection is reliable.

[0075] See Figure 5 and Figure 6 The sealing plate 2 also includes a fourth side 24 opposite to the second side 22. The first side 21 and the third side 23 are smoothly connected to the fourth side 24 through a third arc-shaped edge 213. The first flange 214 extends in an arc shape and is disposed on the third arc-shaped edge 213. This arrangement ensures that the corner of the front end of the sealing plate 2 is relatively smooth, avoiding sharp corners and improving the safety and aesthetics of the range hood casing. For example, the first flange 214 can be integrally bent into the third arc-shaped edge 213.

[0076] Optionally, see Figure 5 The fourth side 24 is provided with a front flange 242, which is fixedly connected to the first flange 214. For example, the first flange 214 is integrally formed at both ends of the front flange 242, so that there is no connection gap on the front side of the front flange 242, and the front side of the entire range hood shell is neat and beautiful. Alternatively, the first flange 214 is welded to both ends of the front flange 242, which simplifies the forming process of the first flange 214 and further reduces the material consumption rate. Alternatively, the front flange 242 and the first flange 214 are integrally formed, and the front flange 242, the first flange 214 and the sealing plate 2 are integrally formed, which simplifies the processing technology, reduces the assembly process, and ensures the overall appearance of the sealing plate 2.

[0077] See Figure 4 and Figure 5 The main body shell 1 forms a smoke collection chamber. The main body plate 11 is provided with a first smoke inlet 110 communicating with the smoke collection chamber, and the sealing plate 2 is provided with a second smoke inlet 20 communicating with the smoke collection chamber. In this embodiment, after the range hood shell is connected to the main unit of the range hood, the first smoke inlet 110 is located on the rear side of the stove area, and the cantilever plate 121 is suspended on the front side of the main body plate 11 (referring to the orientation of the range hood shell during normal use), so that the second smoke inlet 20 on the sealing plate 2 is located above the stove area. When the range hood fan is working, both the first smoke inlet 110 and the second smoke inlet 20 can draw in oil fumes. That is, the combination of side suction and top suction can effectively prevent oil fumes from escaping and improve the smoke exhaust effect of the range hood.

[0078] See Figure 3 The range hood casing also includes a baffle plate 5 disposed on the sealing plate 2. The baffle plate 5 has a hollow convex structure 51 in the area corresponding to the second smoke inlet 20, and the inner cavity of the convex structure 51 is connected to the smoke collection chamber. The convex structure 51 can prevent oil from dripping from the second smoke inlet 20 in the range hood main unit, thereby preventing oil from dripping onto the stove area during cooking. Furthermore, a smoke vent 510 is provided on the convex structure 51. The smoke vent 510 is staggered from the area where the second smoke inlet 20 is located to ensure the blocking effect of the convex structure 51, preventing oil from dripping from the second smoke inlet 20 onto the stove area, while ensuring that the oil fumes drawn in by the second smoke inlet 20 can smoothly enter the smoke collection chamber through the smoke vent 510.

[0079] Optionally, the shield 5 includes a first part and a second part arranged at an angle. The first part covers the area of ​​the sealing plate 2 with the second smoke inlet 20 and is fixedly connected to the sealing plate 2. The second part covers the main body plate 11 and is fixedly connected to the main body plate 11, which can enhance the connection strength between the sealing plate 2 and the main body plate 11.

[0080] Optionally, see Figure 1 and Figure 2The range hood casing also includes a back panel 3. A first opening 14 is formed on the rear side of the main body shell 1 between the first side panel 12 and the second side panel 13. The back panel 3 is connected to the side of the first side panel 12 and the second side panel 13 facing away from the main body plate 11 to seal the first opening 14. The back panel 3, the main body plate 11, the side panel 122 of the first side panel 12, and the side panel 122 of the second side panel 13 enclose a smoke collection chamber for side suction of the range hood casing. The oil fumes drawn in by the first smoke inlet 110 enter this chamber, realizing the side suction function of the range hood.

[0081] Furthermore, the range hood casing also includes a top plate 4. A second opening 15 is formed on the top of the main body shell 1 between the first side plate 12 and the second side plate 13. The top plate 4 is connected to the side of the first side plate 12 and the second side plate 13 facing away from the sealing plate 2, so as to at least partially block the second opening 15. A mounting port 410 is provided in the middle area of ​​the top plate 4. The mounting port 410 is used to connect with the smoke inlet of the main unit, so that a smoke exhaust channel is formed between the smoke collection chamber of the main body shell 1 and the main unit.

[0082] In this embodiment, see Figure 2 The main body shell 1 also includes a bottom sealing plate 16 disposed at the bottom of the main body plate 11.
