[0042] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings.

[0043] See also Figures 1 to 7 The present embodiment provides an integrated stove air duct system, including a bellows 1, a volute fan 2 and a smoke guide pipe 3. The bellows 1 is provided with a cavity 14, a smoke inlet 15 and a smoke pipe port 16. The structure is as follows Figure 1 As shown, the smoke pipe opening 16 is square, the volute fan 2 is arranged in the cavity 14, the smoke guide pipe 3 is arranged in the cavity 14, the air inlet of the smoke guide pipe 3 is connected with the air outlet of the volute fan 2, the air outlet of the smoke guide pipe 3 is connected with the smoke pipe opening 16, the smoke pipe opening 16 is located below the air outlet of the volute fan 2, the smoke guide pipe 3 is arc-shaped, the volute fan 2 and the smoke guide pipe 3 form a spiral smoke exhaust channel (with a long and smooth transition), the structure is as shown Figure 2 As shown, the integrated stove air duct system also includes an adapter 4, the air inlet of the adapter 4 is square, the air inlet of the adapter 4 is detachably connected to the smoke pipe port 16, and the air outlet of the adapter 4 is circular. When the air inlet of the adapter 4 is connected to the smoke pipe port 16, the adapter 4 is used to connect to the circular smoke pipe 110. The structure is as shown in FIG. Figure 4 As shown, when the air inlet of the adapter 4 is removed from the smoke pipe opening 16, the smoke pipe opening 16 is used to connect with the square smoke pipe 10, and the structure is as shown in FIG. Figure 5 shown.

[0044] The bellows 1 is designed with a cavity 14 inside, which not only provides an installation space for the volute fan 2, but also provides a path for the smoke guide duct 3. The volute fan 2 is located in the cavity 14 of the bellows 1, and its function is to generate suction to suck the oil smoke generated during the cooking process into the bellows 1. The smoke guide duct 3 is also arranged in the cavity 14, and its air inlet is connected to the air outlet of the volute fan 2 to ensure that the airflow generated by the fan can smoothly enter the smoke guide duct 3. The smoke guide duct 3 is designed to be arc-shaped, and together with the volute fan 2, it forms a spiral smoke exhaust channel. This design helps the smoke to form a spiral trajectory during the flow process, thereby increasing the air volume and wind speed and improving the smoke exhaust efficiency.

[0045] When the integrated stove is working, the volute fan 2 starts to generate suction. The oil smoke generated during the cooking process is sucked into the cavity 14 of the bellows 1 through the smoke inlet 15 under the action of the suction of the volute fan 2. After the oil smoke enters the smoke guide pipe 3, due to the arc design of the smoke guide pipe 3 and the spiral smoke exhaust channel formed with the volute fan 2, the oil smoke forms a spiral flow in the pipe, which is conducive to the flow of smoke, minimizes the obstruction of the inner cavity of the smoke exhaust channel to the wind, makes it more smoothly ventilated, reduces the loss of air volume, increases the air volume, and improves the smoke exhaust efficiency. The oil smoke is finally discharged through the circular air outlet of the adapter 4, connected to the external circular smoke pipe 110, and the smoke exhaust process is completed.

[0046] In order to increase the applicability of the integrated stove air duct system, a special adapter 4 is designed. The air inlet of the adapter 4 is also square, which can be tightly connected to the smoke pipe port 16 on the wind box 1. The air outlet of the adapter 4 is designed to be circular so as to be connected to the circular smoke pipe 110. In this way, users can choose to use the square smoke pipe 10 or the circular smoke pipe 110 according to their needs, which improves the flexibility of the device.
