As shown in fig. 1 to 8, the cooking appliance includes a pot body 10, a pot cover 20, a pin shaft 30, a torsion spring 40 and a buffer element 50, the pot cover 20 is pivotally connected to the pot body 10 through the pin shaft 30, and the pot cover 20 has a cover closing position where the pot cover is closed on the pot body 10 and a fully opened position after rotating by a first angle from the cover closing position, the torsion spring 40 includes a torsion spring body 41, a first elastic arm 42 and a second elastic arm 43, wherein the torsion spring body 41 is sleeved on the pin shaft 30, the first elastic arm 42 is connected to the pot cover 20 and is disposed to reciprocate in a length direction of the first elastic arm 42 relative to the pot cover 20, and the second elastic arm 43 is connected to the pot body 10 to provide an elastic force for the pot cover 20 to rotate from the cover closing position to the fully opened position; the buffer element 50 is disposed on the lid 20 and corresponds to the end 421 of the first elastic arm 42, and when the lid 20 moves from the lid-closing position to the fully-opening position, the end 421 of the first elastic arm 42 presses against the buffer element 50, so that the buffer element 50 provides buffer resistance for the first elastic arm 42 to hinder the first elastic arm 42 from extending.

By arranging the buffering element 50 on the lid 20 and corresponding to the end 421 of the first elastic arm 42 of the torsion spring 40, in the process of moving the lid 20 from the lid closing position to the full lid opening position, the first elastic arm 42 extends in the length direction of the first elastic arm 42 relative to the lid 20, so that the end 421 of the first elastic arm 42 can press against the buffering element 50, and the buffering element 50 deforms to provide buffering resistance for the first elastic arm 42 to block the first elastic arm 42 from extending, thereby playing a role in buffering lid opening of the lid 20. It can be seen that, compared with the solutions in the related art, the arrangement position of the buffering element 50 in the present application is changed, the assembly of the buffering element 50 with the lid 20 is stable, and the installation space is not affected by the moving part to change, so as to ensure that the buffering element 50 can be effectively pressed by the end 421 of the first elastic arm 42 of the torsion spring 40 during the opening process of the lid 20, buffer the deformation process of the torsion spring 40, and finally reliably implement the lid opening buffering of the lid 20.
