[0006] The cooking utensil provided by the utility model comprises a shell, a connecting pipe, a connecting piece and an exhaust pipe. A cooking cavity is arranged in the shell, and the connecting pipe comprises a first tube body and a second tube body which are connected to each other. The first tube body is connected to the cooking cavity, and the second tube body is arranged at one end of the first tube body, and the second tube body is connected to the exhaust pipe, so that the cooking cavity is connected to the exhaust pipe through the connecting pipe, and the exhaust of the cooking cavity is realized.

The connecting piece is connected to the connecting part outside the cooking cavity, so that the connection pipe is limited inside and outside the cooking cavity, and the reliability of the connection between the connecting pipe and the shell is ensured. Among them, the flange is arranged at the end of the first tube body, and is formed by bending the end of the first tube body outward, so that the first tube body and the flange are formed in one piece, so that there is no need to process the flange-shaped structure on the rod by lathe as in the related art.
