Two air vents 4 are snapped onto the top of the support arm 15.

[0059] Example 3

[0060] In another embodiment, as shown in Figure 5, the side shell 113 is annular. The cooking container 2 is a deep saucepan, and the saucepan includes a cooking zone 21. To further ensure the stability of the cooking container 2, in another embodiment, the cooking container 2 is placed on the fume hood 3 and connected to the exhaust hood 4. The fume inlets 3a are spaced circumferentially on the side wall of the fume hood 3. When the through hole 2a is circular, the cooking zone 21 is arranged around the through hole 2a. Support arms 15 for adapting to the depth of the cooking container 2 are respectively protruding from the outer edges of the left and right ends of the cooking container 2, and a second opening 1c is provided on the top of the support arm 15.

[0061] As shown in Figure 6, the smoke inlet hood 3 is provided with a support structure 12, which is a support surface set on the top outer edge of the smoke inlet hood 3, and the top inner surface of the first protrusion 22 is placed on the support surface. The heating element 7 is a heating plate.

[0062] The fume hood 3 includes a detachable base cover 31 and a cover 32. A smoke inlet 3a is located on the side wall of the cover 32. The base cover 31 has a third opening 31a, with a supporting surface located at the outer edge of the third opening 31a. The fume filtration structure 6 includes a second filter element disposed on the third opening 31a. The top of the base cover 31 has the cover 32 located above the third opening 31a, and the smoke inlets 3a are circumferentially spaced on the side wall of the cover 32. The base cover 31 and the cover 32 are separate components. The cover 32 serves as the cover plate of the fume hood 3, blocking the top of the fume hood 3 and maximizing the suction power on the sides of the fume hood 3 for better smoke extraction. In another embodiment, a third filter element can be disposed on the third opening 31a of the fume hood 3 to further improve the smoke extraction effect and reduce the cleaning frequency of the cavity 1a.

[0063] Example 4

[0064] In other embodiments, compared with embodiment 3, as shown in Figures 7 and 8, the exhaust hood 4 is an annular exhaust hood surrounding the smoke inlet hood 3. The accommodating cavity 2a of the annular exhaust hood is annular. The left and right sides of the annular exhaust hood are respectively provided with slots 2c. There are multiple exhaust ports 4a, which are arranged circumferentially on the inner side wall of the exhaust hood 4. The outer side wall of the exhaust hood 4 is provided with handles 41 opposite to each other, and the two cooperate to form a grip.

[0065] The cooking container 2 is a deep pot, and the cooking pot body 2 is installed on the inner wall of the annular exhaust hood. This allows the fumes to be drawn into the fume hood 3 from 360°, compensating for the insufficient airflow from the exhaust vents 4a on both sides of the fume hood 3 to the fume inlets 3a. Furthermore, the 360° airflow from the annular exhaust hood and the circumferentially spaced fume inlets 3a of the fume hood 3 form a more comprehensive circulation, resulting in better fume extraction covering the entire cooking container 2.

[0066] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
