[0002] The cover plate is one of the parts of the range hood and is used to be installed above the smoke collecting hood. When the cover plate material uses cold plate material, it is easy to deform during the manufacturing and transportation processes, thus affecting the quality and causing waste. To prevent the cover plate from being easily deformed, there are usually two existing solutions: the first is to thicken the cover plate material, but this will increase the cost; the second is to add reinforcing bars, and the reinforcing bars are generally welded on the outer surface of the cover plate, and there will be welding marks after spraying, which affects the appearance.

[0003] The patent document with the application number 202123351296.6 and the publication date of September 9, 2022 in China discloses a cover plate assembly and a range hood thereof.

The cover plate assembly of the utility model has a simple structure and beautiful appearance, and the overall strength of the cover plate is enhanced.

[0004] The flange of this cover plate assembly is arranged at the edge of the cover plate. When the flange and the reinforcing rib are stressed, the impact force caused by the flange and the reinforcing rib on the edge of the cover plate is large, and the cover plate as a whole is a single-layer structure. Therefore, the cover plate is prone to deformation when stressed. Content of the Utility Model

[0040] Embodiment 1

[0041] This embodiment provides a top cover plate 1, which is applied to a range hood and is used to cooperate with the cabinet of the range hood and the hood body 2 of the smoke collecting hood; as Figures 5-7 shown, it includes a top cover plate body 11, an avoidance groove 12 is provided on the top cover plate body 11, and more than one group of bending parts 13 are formed by bending at the edge of the avoidance groove 12. The bending parts 13 include a flattened edge 14 and a supporting straight edge 15. The flattened edge 14 is located below the top cover plate body 11 and is stacked with the top cover plate body 11, and the supporting straight edge 15 is located below the flattened edge 14 and is perpendicular to the flattened edge 14.

[0042] By setting the flattened edge 14, the thickness of the top cover plate body 11 is increased, enhancing the structural strength of the top cover plate 1. At the same time, by means of the flattened edge 14, the force directly acting on the top cover plate body 11 by the supporting straight edge 15 is reduced, lowering the impact force of the supporting straight edge 15 on the top cover plate body 11. Through the cooperation of the supporting straight edge 15 and the flattened edge 14, while enhancing the structural strength of the top cover plate 1, the top cover plate body 11 is not prone to deformation.

[0043] In a preferred embodiment, the supporting straight edge 15 is located on the side of the flattened edge 14 away from the avoidance groove 12. The supporting straight edge 15 is arranged at the edge away from the avoidance groove 12, reducing the force on the edge of the top cover plate body 11 and further reducing the risk of deformation of the top cover plate body 11.

[0044] In a preferred embodiment, the connecting surface between the edge of the avoidance groove 12 and the flattened edge 14 is an arc surface 16. The avoidance groove 12 is used to cooperate with the box body of the range hood. The arc surface 16 is provided to protect the surface of the box body and prevent abrasion of the surface of the box body.

[0045] In a preferred embodiment, there are three groups of the bending parts 13, and the adjacent bending parts 13 are arranged around the avoidance groove 12. There is a notch 17 between the adjacent bending parts 13. By setting a plurality of bending parts 13, the structural strength at different positions of the top cover plate 1 is enhanced; at the same time, the adjacent bending parts 13 are arranged around the avoidance groove 12, with uniform stress; by setting a notch 17 between the adjacent bending parts 13, stress concentration can be avoided.

[0046] Embodiment Two

[0047] This embodiment provides a smoke collecting hood, which is applied to a range hood and is used to cooperate with the box body of the range hood; as Figures 1-7 shown, it includes a top cover plate 1 and a hood body 2. The top cover plate 1 is arranged on the top of the hood body 2 and is connected to the hood body 2; the top cover plate 1 includes a top cover plate body 11, on which there is an avoidance groove 12, and one or more groups of bending parts 13 are formed by bending at the edge of the avoidance groove 12. The bending part 13 includes a flattened edge 14 and a supporting straight edge 15. The flattened edge 14 is located below the top cover plate body 11 and is stacked with the top cover plate body 11, and the supporting straight edge 15 is located below the flattened edge 14 and is perpendicular to the flattened edge 14.

[0048] The hood body 2 is provided with a supporting part 21, and the supporting part 21 includes a first supporting part 22 and a second supporting part 23.

[0049] By setting the flattened edge 14, the thickness of the main body 11 of the large top cover plate is increased, enhancing the structural strength of the top cover plate 1. At the same time, by the flattened edge 14, the force directly acting on the main body 11 of the top cover plate by the supporting straight edge 15 is reduced, lowering the impact force of the supporting straight edge 15 on the main body 11 of the top cover plate. Through the cooperation of the supporting straight edge 15 and the flattened edge 14, while enhancing the structural strength of the top cover plate 1, it is not easy for the main body 11 of the top cover plate to deform. Through the cooperation of the supporting part 21 and the bent part 13, the overall structural strength of the smoke collecting hood is enhanced.

Setting the buffer member 24 to buffer the force generated by the supporting part 21 and the bent part 13 can effectively absorb and disperse the impact force, protecting the hood body 2 and the top cover plate 1 and preventing the hood body 2 and the top cover plate 1 from deforming and being damaged. At the same time, setting the shock-absorbing sponge as the buffer member 24 can also play a sound insulation effect, further improving the noise problem generated when the smoke collecting hood vibrates. Refer to Figure 8 As shown, K1 is the noise data curve of the traditional smoke collecting hood; K2 is the noise data curve of the smoke collecting hood of this embodiment, and the noise problem of the smoke collecting hood of this embodiment is improved.

[0053] In a preferred embodiment, the supporting straight edge 15 is located on the side of the flattened edge 14 away from the avoidance groove 12. The supporting straight edge 15 is arranged at the edge away from the avoidance groove 12, reducing the force on the edge of the main body 11 of the top cover plate, and further reducing the risk of deformation of the main body 11 of the top cover plate.

[0054] In a preferred embodiment, the connecting surface between the edge of the avoidance groove 12 and the flattening edge 14 is an arc surface 16. The avoidance groove 12 is used to cooperate with the box body of the range hood. The arc surface 16 is provided to protect the surface of the box body and prevent wear on the surface of the box body.

[0055] In a preferred embodiment, there are three groups of the bending parts 13, and the adjacent bending parts 13 are arranged around the avoidance groove 12.
