[0026] The utility model will be further explained in detail below according to the drawings and implementation cases.

[0027] In the present specification, the orientation terms such as up, down, left, right, front, back, front surface, back surface, top, bottom and the like mentioned or possibly mentioned are defined with respect to the structure shown in the drawings, and the words "inner" and "outer" refer to the direction towards or away from the geometric center of a particular component, which are relative concepts, so it is possible to change accordingly according to different positions and different use states. Therefore, these or other orientation terms should not be interpreted as restrictive terms.

[0028] Implementation Case 1:

[0029] A wind box is mainly applied in an integrated stove, especially as a part of the lower machine configured for the integrated stove. When cooking, the oil fume is sucked into the upper machine of the integrated stove as a smoke hood, then enters the wind box, and is discharged by the wind box. The wind box of the present implementation case, with reference to Figures 1-5 includes a shell 1 and a fan 2, the fan 2 is installed and arranged in the shell 1, the fan 2 is a volute fan 2 which includes a fan body 22 and an air duct 21. The side plate 11 of the shell 1 has an air outlet 1a, and the air outlet end 21a of the air duct 21 is connected to the air outlet 1a. The top of the shell 1 has an opening, so that the oil fume sucked into the smoke hood can enter the wind box from the opening at the top of the shell 1, and when the wind box is assembled, the fan 2 is also loaded into the shell 1 through the opening at the top of the shell 1, and then the air outlet end 21a of the air duct 21 is connected to the air outlet 1a of the side plate 11, and then the external exhaust pipe is connected.

[0030] In the present implementation case, the lower part of the air outlet end 21a of the air duct 21 is provided with at least one positioning lug 31, which is formed by protruding substantially along the radial direction of the air outlet end 21a, and the side plate 11 of the shell 1 is provided with a supporting structure 111 corresponding to the positioning lug 31. Since the distance between the front plate 12 and the rear plate 13 of the shell 1 is small, the assembly space of the fan 2 in the shell 1 is relatively narrow, resulting in high assembly difficulty. However, since the supporting structure 111 can support the positioning lug 31, when assembling the wind box, the fan 2 is gradually lowered into the shell 1 from the opening at the top of the shell 1, until the supporting structure 111 on the side plate 11 supports the positioning lug 31 on the air outlet end 21a, so that the air outlet end 21a of the air duct 21 can accurately correspond to the mounting position of the air inlet, thereby facilitating the connection and installation of the air outlet end 21a and the side plate 11, and reducing the assembly difficulty.

[0031] In the embodiment, the air outlet end 21a of the air duct 21 is provided with two guide lugs 32, which are similar in structure to the positioning lugs 31 and are formed in a radial direction of the air outlet end 21a. When the fan 2 is installed into the shell 1 through the opening in the top of the shell 1, the two guide lugs 32 are respectively in sliding fit with the front plate 12 and the rear plate 13 of the shell 1. On the one hand, the two guide lugs 32 can guide the installation of the fan 2 to avoid the displacement of the fan 2 in the front-rear direction during the installation, and the air outlet end 21a of the air duct 21 is accurately positioned at the installation position relative to the air outlet 1a when the two positioning lugs 31 are supported on the support structure 111. On the other hand, the sliding fit of the two guide lugs 32 with the front plate 12 and the rear plate 13 can make the process of gradually lowering the fan 2 through the opening in the top of the shell 1 more stable, and avoid the collision between the air duct 21 and the front plate 12 or the rear plate 13.

[0032] In the embodiment, the air outlet end 21a of the air duct 21 is provided with at least one connecting lug 33, which is detachably connected with the side plate 11 of the shell 1. When the fan 2 is lowered into the shell 1 and the air outlet end 21a is accurately positioned at the installation position corresponding to the air outlet 1a under the positioning and guiding of the positioning lugs 31 and the guide lugs 32, the air outlet end 21a of the air duct 21 and the air outlet 1a on the side plate 11 are connected by detachable connection of the connecting lug 33 and the side plate 11.

[0033] In the embodiment, the air outlet end 21a of the air duct 21 is sleeved with a mounting ring 34, and the positioning lugs 31, the connecting lugs 33 and the guide lugs 32 are arranged on the mounting ring 34. The positioning lugs 31, the connecting lugs 33 and the guide lugs 32 can be fixedly connected with the mounting ring 34, or can be integrated with the mounting ring 34. By arranging the mounting ring 34, the positioning lugs 31, the connecting lugs 33 and the guide lugs 32 do not need to be directly fixedly connected with the air outlet end 21a, which reduces the difficulty of manufacturing and processing.

[0034] In the embodiment, the mounting ring 34 is sleeved with a sealing ring 35, which is attached to the edge of the front plate 12 corresponding to the air outlet 1a, so as to enhance the sealing performance of the air outlet end 21a and the air outlet 1a and avoid the leakage of oil droplets during the discharge of oil fume. The sealing ring 35 can be made of rubber, so as to have good elasticity and plasticity, thereby improving the tightness of the sealing.

[0035] In the embodiment, the sealing ring 35 is provided with a clearance hole 351 corresponding to the positions of the positioning lugs 31 and the guide lugs 32, so that the positioning lugs 31 and the guide lugs 32 protrude from the corresponding clearance holes 351. By providing the clearance holes 351, the positioning lugs 31 and the guide lugs 32 are exposed, thereby avoiding friction of the sealing ring 35 on the front plate 12 and the rear plate 13 when the fan 2 is installed, and avoiding the sealing ring 35 being pressed against the support structure 111 by the gravity of the air duct 21 after the fan 2 is installed, so that damage to the sealing ring 35 caused by friction and pressure can be avoided.

[0036] In the embodiment, the sealing ring 35 is provided with a clearance hole 351 corresponding to the positions of the positioning lugs 31 and the guide lugs 32, so that the positioning lugs 31 and the guide lugs 32 protrude from the corresponding clearance holes 351. By providing the clearance holes 351, the positioning lugs 31 and the guide lugs 32 are exposed, thereby avoiding friction of the sealing ring 35 on the front plate 12 and the rear plate 13 when the fan 2 is installed, and avoiding the sealing ring 35 being pressed against the support structure 111 by the gravity of the air duct 21 after the fan 2 is installed, so that damage to the sealing ring 35 caused by friction and pressure can be avoided.

[0037] In the embodiment, the positioning lugs 31 are provided in two and are respectively located on the lower sides of the air outlet end 21a of the air duct 21. When the two positioning lugs 31 are respectively supported on the support structure 111, they are arranged on the lower sides of the air duct 21, so that the stability of the support is better and the air duct 21 does not sway left and right, which is beneficial to the detachable connection of the connecting lugs 33 and the side plate 11. The support structure 111 is arranged along the lower edge of the air outlet 1a and can be provided in a one-piece arc-shaped structure or in a two-piece structure corresponding to the two positioning lugs 31.

[0038] In the embodiment, the air outlet end 21a has space on the upper part and the middle part of the lower part due to the provision of the guide lugs 32 and the positioning lugs 31 on the two sides and the lower sides, respectively. Therefore, the connecting lugs 33 are provided in two and are respectively located on the middle part of the upper part and the middle part of the lower part of the air outlet end 21a of the air duct 21, which not only effectively utilizes the space, but also makes the positions of the two connecting lugs 33 relative to the air outlet end 21a, so that the connection of the connecting lugs 33 and the side plate 11 can enhance the connection firmness of the air duct 21.
