[0054] It can be understood that the passage 3 is enclosed between the cooking part 1 and the shell 2, so that there is a certain gap between the cooking part 1 and the shell 2, thereby reducing the heat transferred from the cooking part 1 to the shell 2. At the same time, when the airflow passes through the passage 3, it can also take away the heat in the passage 3, thereby reducing the ambient temperature of the shell 2. In addition, the first air inlet 20 is arranged on the side of the shell 2 away from the opening 120 in the first direction (for example, the front-to-back direction of the shell 2), so that the first air inlet 20 is arranged on the back side of the shell 2, which can reduce the damage to the appearance of the cooking utensil and improve the aesthetics of the cooking utensil.

[0075] In this embodiment, the end of the extension 442 away from the box body 440 is sealed to the bottom of the shell 2, so that the extension 442 isolates the cooking part 1 from the air duct 49, preventing the heat generated by the cooking part 1 during operation from being drawn into the air duct 49 by the fan and causing the temperature of the electrical components 48 to rise.

[0076] In some embodiments, optionally, the housing 2 has a heat dissipation hole 220 at the bottom in the vertical direction, and the heat dissipation hole 220 is located on the side of the extension 442 away from the first air inlet 20.
