The following description of the inner and outer directions is relative to the cavity of the wind box.
[0042] As shown in Figure 1 , in the embodiment, the integrated cooker only includes the range hood 100 and the gas stove 200. In other embodiments, the integrated cooker can also include a disinfection cabinet, a steam oven, a disinfection cabinet, etc., which are not limited herein.
[0043] As shown in Figure 2 and Figure 3 , the range hood 100 includes an air inlet assembly 30, a fan assembly 40, a wind box 10 and an air outlet cover 20, wherein the fan assembly 40 is arranged inside the wind box 10, the inlet of the air inlet assembly 30 is in communication with the external atmosphere, the outlet is in communication with the inlet of the wind box 10, and the air outlet cover 20 is arranged on the wind box 10 and connected at the air outlet 111 of the wind box 10. When the range hood 100 is working, under the driving of the fan assembly 40, the external oil fume enters from the inlet of the air inlet assembly 30, and then passes through the wind box 10, the fan assembly 40 and is discharged from the air outlet cover 20. In the embodiment, the air inlet assembly 30 is arranged at the rear side of the gas stove 200, the wind box 10 is arranged at the lower side of the gas stove 200, and the air outlet cover 20 is installed at the side of the wind box 10. In other embodiments, the specific arrangement positions of the air inlet assembly 30 and the wind box 10 can be flexibly adjusted as required.
[0044] As shown in Figure 2 , the wind box 10 includes a bottom shell 101 and a cover plate 102, the bottom shell 101 is formed by splicing plate pieces into a box-shaped structure with an open upper end, and the cover plate 102 is arranged at the opening, so that the wind box 10 is constructed as a semi-closed cavity.
[0045] In the embodiment, as shown in Figure 3 and Figure 4 , the bottom shell 101 includes a bottom plate 13 and a side plate 11, the side plate 11 is located in a vertical plane, and the bottom plate 13 is connected below the side plate 11 and located in a horizontal plane, and the air outlet 111 is arranged on the side plate 11.
[0046] In the case of long-time operation of the range hood 100, the oil fume entering the wind box 10 will condense into oil droplets on the surface of the fan assembly 40, the inner wall of the wind box 10 and the like, in order to avoid excessive accumulation of oil droplets in the wind box 10, as Figure 4As shown, the bottom plate 13 is configured in a ring shape, and the bottom shell 101 further comprises a flow guide 14 configured in a funnel shape and arranged below the fan assembly 40. The flow guide 14 is provided with an oil inlet at the upper end and an oil outlet hole 15 at the lower end, and the oil inlet and the oil outlet hole 15 are communicated. The large-diameter end (upper end) of the funnel-shaped flow guide 14 faces upwards and is connected to the bottom plate 13, that is, the flow guide 14 is indirectly connected between the bottom plate 13 and the side plate 11. The small-diameter end (lower end) of the funnel-shaped flow guide 14 faces downwards and forms the oil outlet hole 15. The funnel-shaped flow guide 14 forms an inclined surface, and the oil droplets deposited on the inner wall of the bellow 10 can flow along the inner wall into the flow guide 14, and the oil droplets on the surface of the fan assembly 40 can also drip into the flow guide 14, and finally be discharged from the oil outlet hole 15.
[0047] In the case of long-time operation of the range hood 100, oil may also be deposited at the connection position of the bellow 10 and the air outlet cover 20, and then seep out to the outside of the bellow 10, that is, oil leakage occurs. In the related art, a sealing gasket is usually arranged at the connection position of the air outlet cover and the bellow to alleviate the oil leakage. However, this solution increases the number of components and is inconvenient for assembly, and the sealing gasket may also fail after long-time use.
[0048] To this end, as shown in the drawings, Figures 3-7 The bellow and the air outlet cover are connected by a connection structure. As shown in the drawings, Figure 4 The bellow 10 further comprises a sinking wall 12. Specifically, the sinking wall 12 and the folding portion 16 are formed by concavely arranging the edge of the upper end of the air outlet 111 on the side plate 11 towards the inside of the bellow 10.

The flange 22 comprises an upper end portion 221 and a lower end portion 222. The bottom of the flange 22 is located on the lower end portion 222, and the upper end portion 221 is provided with a first sinking groove 2211. As shown in the drawings, Figure 3 、 Figures 6-7 The flange 22 is inserted into the air outlet 111, so that the groove bottom surface of the first sinking groove 2211 abuts against the side surface of the sinking wall 12 away from the inside of the bellow 10, and the lower end portion 222 is arranged opposite to and spaced apart from the side surface of the side plate 11 towards the inside of the bellow 10.
[0049] In the connection structure of the bellow and the air outlet cover, the groove bottom surface of the first sinking groove 2211 abuts against the sinking wall 12, and the mating surface of the flange 22 is pulled into the inside of the bellow 10,Figure 3 The dashed arrow in the figure indicates the flow direction of the oil liquid, when the oil liquid with deposition flows downwards from the inner wall of the side plate 11, it is first guided to the inside of the bellow 10 through the deposition wall 12, then the oil liquid flows downwards along the deposition wall 12 or the flange 22 to the lower end portion 222 of the flange 22, since the lower end portion 222 of the flange 22 is oppositely arranged and spaced apart from the side surface of the side plate 11 towards the inside space of the bellow 10, the oil drops at this position will not contact the part of the side plate 11 at the edge of the air outlet 111, and the oil liquid will finally drip along the lower end portion 222 of the flange 22 to the inside space of the bellow 10, and finally discharged from the oil outlet hole 15, that is, the problem of oil leakage at the connection between the bellow 10 and the air outlet cover 20 is solved through the cooperation of the mechanical structure, the sealing reliability of the structure is good, and the service life is long, and no additional sealing element is needed, so the cost is low and the assembly is convenient.
[0050] As shown in Figure 4 and Figure 5 , the opening of the air outlet 111 is rectangular, the extension trajectory of the deposition wall 12 is inverted U-shaped, the extension trajectory thereof is open towards the side of the bottom of the bellow 10, the extension trajectory of the first deposition groove 2211 is the same as that of the deposition wall 12, so that the groove bottom surface of the first deposition groove 2211 is reliably abutted with the outer surface of the deposition wall 12. In addition, the U-shaped deposition wall 12 can more comprehensively guide the oil drops above to the two sides of the air outlet 111 and flow to the bottom plate 13, thereby improving the sealing reliability of the connection structure of the bellow and the air outlet cover.
[0051] In the embodiment, as shown in Figures 5-7 , the first deposition groove 2211 is arranged at the edge of the upper end portion 221 of the flange 22, and the air inlet end side of the entire flange 22 is abutted with the edge of the air outlet of the shell of the fan assembly 40, so as to facilitate the oil fume in the fan assembly 40 to smoothly enter the air outlet cover 20. In the embodiment, the upper end portion 221 of the flange 22 is connected with the deposition wall 12 through a fastener, and optionally, the fastener can be a bolt.
[0052] Obviously, the above embodiments of the utility model are only examples for clearly illustrating the utility model, and are not a limitation on the embodiments of the utility model. For ordinary skilled in the art, according to the idea of the utility model, the specific embodiments and application range can be changed, and the content of the specification should not be understood as a limitation on the utility model.
