[0032] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0033] Reference is made below to Figures 1 - 3 describe an air duct assembly 100 for an air handling device according to an embodiment of the present invention.

[0034] As Figure 1 and Figure 3 shown, the air handling device includes a back plate 200 and an air duct assembly 100. In the vertical direction from top to bottom, the width of the back plate 200 gradually increases, that is to say, the back plate 200 has an upper-narrow and lower-wide structure. The air inlet end of the air duct assembly 100 is connected to the back plate 200, and the width of the air inlet end gradually increases in the vertical direction from top to bottom.

[0035] When assembling the air duct assembly 100 and the back panel 200, the narrower end of the air inlet end of the air duct assembly 100 can be connected to the narrower end of the back panel 200, and the wider end of the air inlet end of the air duct assembly 100 can be connected to the wider end of the back panel 200, so as to realize the connection between the air duct assembly 100 and the back panel 200. Thus, the air inlet end of the air duct assembly 100 can better match the back panel 200, facilitating the connection between the air duct assembly 100 and the back panel 200, and ensuring the reliability of the connection between the air duct assembly 100 and the back panel 200. In addition, the width of the air inlet end gradually increases in the direction from top to bottom, thereby enhancing the recognition of the air duct assembly 100 and having an anti-fooling function.

[0036] For the air duct assembly 100 of the air handling device according to the embodiment of the present invention, in the direction from top to bottom, the width of the air inlet end of the air duct assembly 100 gradually increases, and the air inlet end of the air duct assembly 100 can better match the back panel 200 with a narrower top and a wider bottom, so as to reduce the difficulty of connecting the air duct assembly 100 and the back panel 200 and improve the reliability of the connection between the air duct assembly 100 and the back panel 200. In addition, the width of the air inlet end gradually increases in the direction from top to bottom, thereby enhancing the recognition of the air duct assembly 100 and having an anti-fooling function.

[0037] According to some embodiments of the present invention, such as Figure 1 and Figure 3 shown, the air duct assembly 100 includes a volute body 1, and the width of the volute body 1 gradually increases in the direction from top to bottom for connection with the back panel 200. It can be understood that in the direction from top to bottom, the width of the back panel 200 also gradually increases. Thus, the volute body 1 can match the back panel 200 in shape. During assembly, the relative position between the air duct assembly 100 and the back panel 200 can be adjusted according to the changes in the widths of the air duct assembly 100 and the back panel 200, so as to reduce the difficulty of assembling the air duct assembly 100 and improve the assembly accuracy of the air duct assembly 100.

[0038] According to some embodiments of the present invention, such as Figure 1 and Figure 3 shown, the air duct assembly 100 includes: a volute body 1, a first side plate 2 and a second side plate 3. The first side plate 2 and the second side plate 3 are respectively connected to both ends in the width direction of the air inlet end of the volute body 1. In the direction from top to bottom, the width of at least one of the first side plate 2 and the second side plate 3 gradually increases, and the first side plate 2 and the second side plate 3 are respectively connected to both ends in the width direction of the back panel 200.

[0039] It can be understood that in the up-down direction, it can be that only the width of the first side plate 2 gradually increases, or only the width of the second side plate 3 gradually increases, or the widths of both the first side plate 2 and the second side plate 3 gradually increase. By providing the first side plate 2 and the second side plate 3, the relative positions of the first side plate 2 and the second side plate 3 connected to the volute body 1 can be adjusted, so as to realize the adjustment of the relative position between the volute body 1 and the back plate 200, and further ensure the reliability of the connection between the volute body 1 and the back plate 200.

[0040] Furthermore, as Figure 1 and Figure 2 shown, in the up-down direction, the width of the volute body 1 is consistent. Compared with the volute body 1 with different widths in the up-down direction, the volute body 1 with the same width in the up-down direction has a more mature manufacturing process, lower production and manufacturing costs, a higher yield rate, stronger reliability, and is beneficial to shortening the manufacturing cost of the volute body 1.

[0041] In some embodiments of the present invention, as Figure 1 and Figure 2 shown, the first side plate 2 and the second side plate 3 and the volute body 1 are integral parts. Thus, the integral parts can not only ensure the structural and performance stability of the first side plate 2, the second side plate 3 and the volute body 1, but also are convenient for forming, simple to manufacture, and moreover, the redundant fittings and connection processes are omitted, greatly improving the assembly efficiency of the first side plate 2, the second side plate 3 and the volute body 1, ensuring the connection reliability of the first side plate 2, the second side plate 3 and the volute body 1. Furthermore, the integral parts have higher overall strength and stability and longer service life.

[0042] In some embodiments of the present invention, as Figure 1 and Figure 2 shown, the first side plate 2 and the second side plate 3 and the volute body 1 are connected by threaded fasteners or snap connections. Both the threaded fastener connection and the snap connection have the advantages of easy assembly. The first side plate 2, the second side plate 3 and the volute body 1 can be tightly connected by threaded fastener connection or snap connection. In addition, the cost can be reduced while ensuring the connection strength between the first side plate 2, the second side plate 3 and the volute body 1. Optionally, the threaded fastener can be a screw, a bolt or a stud.

[0043] In some embodiments of the present invention, as Figure 1 and Figure 3As shown, in the vertical direction from top to bottom, the widths of the first side plate 2 and the second side plate 3 both gradually increase. It can be understood that in the vertical direction from top to bottom, the width of the back plate 200 gradually increases. The first side plate 2 and the second side plate 3 are respectively connected to both sides of the volute body 1 in the width direction. Thus, in the vertical direction from top to bottom, the width of the air duct assembly 100 also gradually increases. As a result, the air duct assembly 100 can match the back plate 200 in appearance. During assembly, the relative position between the air duct assembly 100 and the back plate 200 can be adjusted according to the changes in the widths of the first side plate 2, the second side plate 3, and the back plate 200. Thereby, the difficulty of assembling the air duct assembly 100 can be reduced, and the assembly accuracy of the air duct assembly 100 can be improved.

[0044] Furthermore, as Figure 1 and Figure 2 shown, the first side plate 2 and the second side plate 3 are symmetrical. Thereby, the design and manufacturing costs of the first side plate 2 and the second side plate 3 can be reduced, making the structures of the first side plate 2 and the second side plate 3 simpler, which is beneficial to shortening the production cycle of the first side plate 2 and the second side plate 3.

[0045] In some embodiments of the present invention, as Figure 1 and Figure 3 shown, both the first side plate 2 and the second side plate 3 are connected to the back plate 200 through threaded fasteners. Threaded fasteners have the advantages of simple structure and easy assembly. Through the threaded fasteners, a tight connection between the first side plate 2, the second side plate 3, and the back plate 200 can be achieved. In addition, while ensuring the connection strength between the first side plate 2, the second side plate 3, and the back plate 200, the cost can be reduced. Optionally, the threaded fasteners can be screws, bolts, or studs.

[0046] Furthermore, as Figure 1 and Figure 3 shown, multiple through holes 4 for the threaded fasteners to pass through are provided on both the first side plate 2 and the second side plate 3. It can be understood that when the first side plate 2 and the second side plate 3 are connected to the back plate 200, the threaded fasteners can pass through the through holes 4 of the first side plate 2 and the second side plate 3 and be fixed on the back plate 200, thereby ensuring the connection strength between the first side plate 2, the second side plate 3, and the back plate 200 and enhancing the connection stability.

[0047] Furthermore, as Figure 1 and Figure 3As shown, at least some of the through holes 4 on the first side plate 2 are oblong holes, and at least some of the through holes 4 on the second side plate 3 are oblong holes. Thus, when the first side plate 2 and the second side plate 3 are matingly connected to the back plate 200, the threaded fasteners can move within the oblong holes, enabling the threaded fasteners to be matingly connected to the connection holes on the back plate 200. This can reduce the difficulty of connecting the first side plate 2, the second side plate 3 to the back plate 200 and improve the assembly efficiency. In addition, it can also avoid the problem of difficult assembly caused by machining errors, thereby reducing the requirements for the machining accuracy of the first side plate 2, the second side plate 3 and the back plate 200, and further reducing the machining cost.

[0048] In some embodiments of the present invention, as Figure 1 and Figure 3 shown, a plurality of limiting holes are provided on both the first side plate 2 and the second side plate 3, and limiting posts mating with the limiting holes are provided on the back plate 200. Thus, the limiting posts have the functions of limiting and positioning the first side plate 2 and the second side plate 3. The first side plate 2 and the second side plate 3 can achieve high-precision matching with the back plate 200 through the limiting posts, thereby improving the reliability of the connection between the first side plate 2, the second side plate 3 and the back plate 200.

[0049] In some embodiments of the present invention, as Figure 1 and Figure 3 shown, a plurality of reinforcing ribs 5 are provided on the sides of the first side plate 2 and the second side plate 3 away from the back plate 200. Thus, the structural strength of the first side plate 2 and the second side plate 3 can be improved, ensuring the reliability of the operation of the first side plate 2 and the second side plate 3, and being beneficial to extending the service life of the first side plate 2 and the second side plate 3.

[0050] Furthermore, as Figure 1 and Figure 2 shown, one end of the reinforcing rib 5 is connected to the volute body 1. Thus, the connection strength between the first side plate 2, the second side plate 3 and the volute body 1 can be improved, ensuring the reliability of the connection between the first side plate 2, the second side plate 3 and the volute body 1.

[0051] Next, reference is made to Figures 1 - 3 to describe the air handling device according to an embodiment of the present invention.

[0052] The air handling device according to an embodiment of the present invention includes the above-described air duct assembly 100 for an air handling device.

[0053] In the air handling device according to an embodiment of the present invention, in the vertical direction from top to bottom, the width of the air inlet end of the air duct assembly 100 gradually increases. The air inlet end of the air duct assembly 100 can better match the back plate 200 with a narrower top and wider bottom, thereby reducing the difficulty of connecting the air duct assembly 100 to the back plate 200 and improving the reliability of the connection between the air duct assembly 100 and the back plate 200. In addition, the width of the air inlet end gradually increases in the vertical direction from top to bottom, thereby enhancing the recognition of the air duct assembly 100 and having an anti-misoperation function.
