Air cabinet mounting structure and range hood

Abstract

The utility model provides an air cabinet installation structure which comprises an air cabinet body, the air cabinet body is provided with a front plate, a rear plate and a surrounding plate, outer limiting ribs are arranged on the front plate and the rear plate, the outer limiting ribs protrude inwards, turnover plates are arranged on the two sides of the surrounding plate, the turnover plates are installed between the front plate and the rear plate, and the outer limiting ribs protrude inwards. An angle R is formed at the connecting position of the folding plate and the surrounding plate, and the height of the outer limiting ribs is equal to or slightly larger than the radius of the angle R. The outer limiting ribs are arranged on the front plate and the rear plate and protrude inwards, so that the installation position of the surrounding plate can be limited, and due to the fact that the angle R can be generated when the folding plate is formed by the surrounding plate, the installation position of the surrounding plate can be limited. When the coaming is installed on the front plate and the rear plate, the outer limiting rib protrudes inwards and blocks the turnover plate, air leakage at the bent position of the turnover plate and the coaming is avoided, standardization of the air cabinet is improved, the reject ratio is reduced, and meanwhile the air tightness of the volute of the air cabinet is improved.

Description

Technical Field

[0001] This utility model relates to a fan cabinet installation structure and a range hood. Background Technology

[0002] The volute is an essential component of a range hood. Existing volutes are generally composed of a front panel, a rear panel, and a side panel. The side panel is welded or riveted to the front and rear panels respectively. However, in this production process, it usually depends on the skill of the workers to connect the side panel between the front and rear panels in a specific shape. This installation method is difficult to standardize, resulting in inconsistent quality and is prone to air leakage caused by incomplete or poor welding. Utility Model Content

[0003] This utility model proposes a fan cabinet installation structure, including a fan cabinet body. The fan cabinet body is provided with a front plate, a rear plate, and a surrounding plate. The front plate and the rear plate are provided with outer limiting ribs that protrude inward. Folding plates are provided on both sides of the surrounding plate. The folding plates are installed between the front plate and the rear plate. The connection between the folding plates and the surrounding plate forms an R-angle. The height of the outer limiting ribs is equal to or slightly higher than the radius of the R-angle.

[0004] In one or more embodiments, both the front plate and the rear plate are provided with inner limiting ribs, and an installation groove is formed between the inner limiting ribs and the outer limiting ribs, the width of the installation groove being equal to the width of the folding plate.

[0005] In one or more embodiments, the height of the inner limiting rib is equal to or slightly higher than the thickness of the surrounding plate.

[0006] In one or more embodiments, the folding plate is welded together with the front plate and the rear plate, respectively.

[0007] In one or more embodiments, the front panel, rear panel, and perimeter panel are provided with a spray coating.

[0008] A range hood includes the aforementioned fan housing mounting structure.

[0009] The beneficial effects of this utility model are as follows: By providing external limiting ribs on the front and rear plates, which protrude inward, the installation position of the enclosure can be restricted. Furthermore, since the enclosure will generate an R-angle when it forms a folded plate, when the enclosure is installed on the front and rear plates, the external limiting ribs protrude inward and block the folded plate, thus preventing air leakage at the bend of the folded plate and the enclosure. This not only improves the standardization of the air handling unit and reduces the defect rate, but also improves the airtightness of the air handling unit volute. Attached Figure Description

[0012] The following description, in conjunction with the accompanying drawings, further illustrates the proposed solution:

[0013] See appendix Figure 1-2 A fan cabinet installation structure includes a fan cabinet body, which is provided with a front plate 1, a rear plate 2, and a surrounding plate 3. The front plate 1 and the rear plate 2 are provided with outer limiting ribs 4, which protrude inwards, i.e., protrude towards the air duct inside the fan cabinet body. Folding plates 31 are provided on both sides of the surrounding plate 3. The folding plates 31 are installed between the front plate 1 and the rear plate 2. The connection between the folding plates 31 and the surrounding plate 3 forms an R-angle 32. The height of the outer limiting ribs 4 is equal to or slightly higher than the radius of the R-angle.

[0014] Preferably, the outer limiting rib 4 is close to the outer edge of the front plate 1 and the rear plate 2, and the outer edge of the front plate 1 and the rear plate 2 may also be provided with a folded edge to increase the strength of the front plate 1 and the rear plate 2.

[0015] Furthermore, both the front plate 1 and the rear plate 2 are provided with inner limiting ribs 5, and an installation groove 6 is formed between the inner limiting ribs 5 and the outer limiting ribs 4. The width of the installation groove 6 is equal to the width of the folding plate 31.

[0016] Furthermore, the height of the inner limiting rib 5 is equal to or slightly higher than the thickness of the surrounding plate 3.

[0017] Furthermore, the folding plate 31 is welded together with the front plate 1 and the rear plate 2 respectively.

[0018] Furthermore, the front panel 1, the rear panel 2, and the surrounding panel 3 are provided with a spray coating.

[0019] A range hood includes the aforementioned fan housing mounting structure.
