[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1 to 4 shown,

[0021] A direct exhaust air duct structure in an integrated stove, characterized in that it includes an air box 1, the air box 1 is integrally formed by sheet metal, a negative pressure cavity 2 and a smoke collection cavity 3 are provided in the air box 1, an air outlet 4 is provided below the side of the smoke collection cavity 3, a fan system 5 is provided in the smoke collection cavity 3, a smoke collection cavity upper cover 6 is inclinedly arranged at the upper end of the smoke collection cavity 3, the bottom of the smoke collection cavity 3 is funnel-shaped, and a waste oil hole 7 is provided at the lower end of the smoke collection cavity 3.

[0022] In this embodiment, through the negative pressure chamber 2 and the fan system 5, the cooking fume is inhaled into the smoke collection chamber 3. The collected waste oil is discharged from the waste oil hole 7, and the flue gas is discharged from the air outlet 4. The bottom of the smoke collection chamber 3 is funnel-shaped to facilitate the collection of waste oil. The upper cover 6 of the smoke collection chamber is inclined to facilitate the collection of waste oil and prevent risks such as oil leakage. The entire air box 1 adopts an integral molding process to increase the strength of the sheet metal, reduce the noise of the whole machine, and prevent the resonance of the sheet metal.

[0023] In this embodiment, the fan system 5 includes a volute, a motor, and a wind wheel. The volute is arranged in the smoke collection chamber 3, the motor and the wind wheel are arranged on the volute, and the air outlet end of the volute is inserted into the air outlet 4. The insertion of the air outlet end of the volute into the air outlet 4 reduces the wind resistance and noise, improves the air volume, and is easy to install.

[0024] In this embodiment, several heat dissipation holes 8 and oil drainage holes 9 are provided on the upper cover 6 of the smoke collection chamber. The upper cover 6 of the smoke collection chamber is provided with several heat dissipation holes 8 to cause air convection inside the integrated stove and reduce the internal temperature rise.

[0025] In this embodiment, the air outlet 4 adopts an integral molding and flanging process. The air outlet 4 adopting the integral molding and flanging process effectively improves the air volume, reduces the wind resistance, and reduces the noise.

[0026] In this embodiment, the waste oil hole 7 is a flanging design. The waste oil hole 7 adopting the flanging design prevents the blockage of waste oil.
