It should be further understood that the term "comprising" used in the specification of this application refers to the presence of the described features, integers, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or groups thereof.

[0046] First, the nouns involved in this application are introduced and explained:

[0047] The Archimedean spiral, also known as the constant velocity spiral, is named after the Greek mathematician Archimedes of the third century BC. An Archimedean spiral is the path of a point moving away from a fixed point at a constant speed while simultaneously rotating around that fixed point at a constant angular velocity.

[0048] The following describes in detail the technical solution of the present application and how the technical solution of the present application solves the technical problem with specific embodiments.

[0049] like Figure 1 As shown, an embodiment of the present application provides a side panel for use in a range hood volute. The side panel 1 primarily comprises multiple reinforced areas and protrusions. The reinforced areas are arranged sequentially along an involute, with the widths of the reinforced areas increasing sequentially along the involute's involute direction. The protrusions are formed within at least one of the reinforced areas and extend along the involute's involute direction.

[0050] In this embodiment, an air duct is formed within the volute and is located on one side of the side panel 1. Multiple reinforced areas and protrusions on the side panel 1 correspond to the air duct, with the protrusions projecting away from the air duct. The profile of the side panel 1 is an Archimedean spiral, and the involute of the side panel 1 is arranged along the Archimedean spiral.

[0051] The widths of the multiple reinforced areas of side panel 1 increase sequentially along the involute direction of the side panel 1. The size of the reinforced areas is tailored to the volume of airflow through the duct, ensuring that areas with greater airflow have correspondingly larger reinforced areas, thereby enhancing the overall strength of side panel 1. Defining the multiple reinforced areas with contoured areas extending along the involute direction of the side panel 1 prevents airflow obstruction and the resulting reduction in smoke exhaust efficiency. The contouring also creates a cross-sectional change that produces sufficient pressure diffusion, reducing vibration and noise caused by airflow.

[0052] like Figure 1-2 As shown, as an optional embodiment, the multiple reinforcement areas include a first reinforcement area 13, a second reinforcement area 14 and a third reinforcement area 15 arranged in sequence; the width of the first reinforcement area 13, the width of the second reinforcement area 14 and the width of the third reinforcement area 15 increase in sequence along the involute direction of the involute; the protruding ends of all the embossed protrusions are formed with a planar portion, and the planar portions of all the embossed protrusions are located in the same plane.

[0053] Based on the previous embodiment, in this embodiment, the first reinforced region 13, the second reinforced region 14, and the third reinforced region 15 are arranged sequentially along the involute direction of the involute. The first reinforced region 13 is formed by three boundaries, the second reinforced region 14 is formed by four boundaries, and the third reinforced region 15 is formed by five boundaries. The protruding ends of all the embossed protrusions have the same protruding height and are all flat.

[0054] Optionally, the protruding height of the protruding ends of all the embossed protrusions is greater than or equal to 2.5 mm and less than or equal to 3.5 mm.

[0055] As a preferred embodiment, the protruding height of the protruding ends of all the embossed protrusions is equal to 3 mm.

[0056] like Figure 1-2 As shown, as an optional embodiment, the side panel 1 also includes a plate body 11 and a circular opening 12 opened in the plate body 11; multiple reinforcement areas are located in the plate body 11; the end boundary of the first reinforcement area 13 close to the second reinforcement area 14, and the end boundary of the second reinforcement area 14 close to the first reinforcement area 13 both extend radially along the circular opening 12.

[0057] like Figure 1-2 As shown, based on the above embodiment, in this embodiment, the first reinforced area 13, the second reinforced area 14 and the third reinforced area 15 can be divided according to the following method:

[0058] The coordinate axis of the preset coordinate system is used as the dividing line for dividing the board 11 into four areas;

[0059] The area where the tongue V is located is used as the first area 111 of the plate body;

[0060] Along the involute direction of the side panel 1, the remaining three areas are sequentially designated as the second plate area 112, the third plate area 113, and the fourth plate area 114. An air outlet portion is provided on one side of the volute tongue V within the first plate area 111. The air outlet portion includes a first edge F, a second edge G, and a third edge H, which are sequentially connected. The first edge F and the third edge H are disposed opposite each other. The first edge F is a portion of the outer edge of the plate 11, and the third edge H is close to the volute tongue V.

[0061] The boundary line between the third plate area 113 and the fourth plate area 114 is rotated about the origin of the preset coordinate system toward the direction of the third plate area 113 by a preset angle as the first auxiliary line Q;

[0062] A line formed by translating the boundary line between the first plate area 111 and the fourth plate area 114 into the fourth plate area 114 by a preset first distance serves as the second auxiliary line W.

[0063] The plate body 11 forms an inner boundary E at a preset second distance from the inner edge of the plate body 11;

[0064] The plate body 11 forms an outer boundary R at a preset third distance from the outer edge of the plate body 11;

[0065] On opposite sides of the first auxiliary line Q, a first end boundary T and a second end boundary D are formed at a predetermined fourth distance from the first auxiliary line Q;

[0068] The area enclosed by the inner boundary E, the outer boundary R, the second end boundary D and the third end boundary U serves as the second reinforced area 14;

[0069] A transition boundary O is formed at a third distance between the plate body 11 and the third edge H;

[0070] A fifth end boundary P is formed at a preset fifth distance between the plate body 11 and the second edge G;

[0071] An area enclosed by the transition boundary O, the inner boundary E, the outer boundary R, the fourth end boundary I, and the fifth end boundary P serves as a third reinforced area 15 .

[0072] Specifically, the profile of the side panel 1 has a center point, which is the center of the circular opening 12. Figure 1-2 As shown, a plane XY axis rectangular coordinate system is established with the center of the circular opening 12 as the origin; wherein the X axis is set horizontally and the Y axis is set vertically.

[0073] The first plate region 111, the second plate region 112, the third plate region 113, and the fourth plate region 114 are located in four different quadrants of a predetermined coordinate system. These four regions are arranged along the involute of the side panel 1, i.e., in a clockwise or counterclockwise direction. These four regions are arranged in the direction of airflow and the direction of increasing airflow through the duct. This approach lays a foundation for the subsequent division of reinforcement regions, ensuring the overall strength of the side panel 1.

[0074] In the present application, the areas divided by the plate body 11, the auxiliary lines made, and the divided reinforcement areas can be adjusted and designed according to actual conditions.

[0075] Assume that the boundary between the third plate area 113 and the fourth plate area 114 is the first boundary, which is the semi-axis with the Y axis above the X axis. Assume that the boundary between the first plate area 111 and the fourth plate area 114 is the second boundary, which is the semi-axis with the X axis to the right of the Y axis. The first boundary is rotated counterclockwise around the origin of the target coordinate system by a preset angle to the left to form a first auxiliary line Q. The second boundary is translated upward by a first distance to form a second auxiliary line W.

In the subsequent embodiments, the intersections of the boundary lines and / or the contour lines may also be set with an R angle, which will not be described in detail.

[0085] The second auxiliary line W is arranged horizontally. The upper side of the second auxiliary line W forms a third end boundary U, which is close to the boundary between the third and fourth plate regions 113, 114.

[0086] The outer edge of the plate 11 includes a curved segment and a straight segment. The curved segment is arranged along an Archimedean spiral, and the straight segment represents the first edge F of the air outlet. The third edge H is a straight structure. Assuming that the second edge G of the air outlet is horizontal, the resulting fifth end boundary P is also horizontal.
