[0029] The following examples are used to illustrate the present application, but the present application is not limited to these examples. Modifications to the specific embodiments of the present application or equivalent replacements to some technical features are made without departing from the spirit of the present application, which should be covered in the technical solution range claimed by the present application.

[0030] Example 1

[0031] Reference Figures 1-4 The present embodiment provides a shell assembly of a side suction type range hood, the shell assembly comprising an integrally formed shell 1, the integrally formed shell 1 having a smoke collection cavity (not shown in the figure), a top opening 102 and a front opening 101, the smoke collection cavity being in communication with the front opening 101 and the top opening 102 respectively. In the present embodiment, the integrally formed shell 1 comprises a back plate 11, a bottom plate 12, two side plates 13 and two top plates 14, the back plate 11 being arranged vertically. The bottom plate 12 is arranged horizontally and is formed by bending the lower end of the back plate 11 forward. The two side plates 13 are formed by bending the left and right ends of the back plate 11 forward and outward of the smoke collection cavity, and the lower edges of the two side plates 13 are respectively welded to the left and right edges of the bottom plate 12 to fixedly connect the side plates and the bottom plate 12 as a whole, and the front opening 101 is formed between the front end portions of the two side plates 13 above the bottom plate 12. The two top plates 14 are formed by bending the upper ends of the two side plates 13 inward of the integrally formed shell 1, and the top opening 102 is formed between the two top plates 14 in front of the back plate 11.

[0032] As can be seen, the integrally formed shell 1 comprises the back plate 11, the bottom plate 12, the two side plates 13 and the two top plates 14, compared with the shell of the existing side suction type range hood, the forming process is simple, the production efficiency is improved, the number of parts is simplified, and the cost is reduced.

[0033] Reference Figures 2-4 Specifically, the side plate 13 is arranged obliquely from bottom to top and inward of the integrally formed shell 1, and the side plate 13 is arranged obliquely from front to back and inward of the integrally formed shell 1, so that the integrally formed shell 1 is a tapered and contracted shell, the volume of the shell is reduced, a visually ultra-thin appearance is formed, compared with the existing triangular side suction machine, the internal space of the shell is compressed, the impact and backflow of airflow in the shell is reduced, a built-in flow guide plate is not needed, and the air guide and flow guide effects can be achieved, which is beneficial to rapid smoke exhaust and cost reduction.

[0034] In the embodiment, the back plate 11 is trapezoidal with a small lower end and a large upper end, the bottom plate 12 is trapezoidal with a small rear end and a large front end, the two side plates 13 are trapezoidal with a small lower end and a large upper end, and the two top plates 14 are triangular with a small rear end and a large front end. Since the bottom plate 12 is trapezoidal with a small rear end and a large front end, and the two side plates 13 are arranged from front to rear and inclined towards the inside of the integrally formed shell 1, the formed front opening 101 has a larger area, which is beneficial to increase the unit air inlet area and improve the smoking effect. In addition, the two side plates 13 are arranged from front to rear and inclined towards the inside of the integrally formed shell 1, and the two top plates 14 are triangular with a small rear end and a large front end, so that the rear end of the top plate 14 and the upper end of the back plate 11 do not need to be welded, reducing the welding process, improving production efficiency, and reducing cost.

[0035] Reference Figures 1-2 In the embodiment, the left and right edges of the bottom plate 12 are welded to the lower edges of the two side plates 13 to form a first welding position, which improves the connection strength and prevents oil from seeping out of the first welding position. The front end of the bottom plate 12 is bent upwards to form a lower flange 121, and the left and right edges of the lower flange 121 are welded to the lower ends of the front edges of the two side plates 13 to form a second welding position, which effectively improves the connection strength between the lower flange 121 and the side plate 13 and prevents oil inside the integrally formed shell 1 from seeping out of the second welding position. The front end of the side plate 13 is bent to form a side flange 131 above the lower flange 121, and the lower edge of the side flange 131 is welded to the left or right end of the upper edge of the lower flange 121 to form a third welding position, which effectively improves the connection strength between the side flange 131 and the lower flange 121.

[0036] Reference Figures 1-4 Further, the integrally formed shell 1 further comprises two circular arc reinforcing portions 15, which are arranged between the side plate 13 and the top plate 14 to improve the overall strength and appearance of the integrally formed shell 1, so that the integrally formed shell 1 will not be deformed by the impact force caused by falling, and has stronger anti-falling ability. The front edge of the circular arc reinforcing portion 215 is welded to the upper edge of the side flange 131 to form a fourth welding position, which improves the connection strength between the two.

[0037] In the embodiment, the circular arc reinforcing portion 215 is a gradually changing circular arc plate, and the radius of the circular arc of the gradually changing circular arc plate gradually decreases from front to rear. When the integrally formed shell 1 falls, the circular arc reinforcing portion 215 disperses the impact force on the integrally formed shell 1 to the entire contact surface, avoiding deformation caused by concentrated impact force.
