The cooking appliance is an electric pressure cooker, as shown in fig. 2 to 6, and comprises a cooker body 2 and an upper cover 1 covering the cooker body 2, wherein a water tank 4 is arranged on the cooker body 2, and the water tank 4 can be communicated with a cavity in the upper cover 1 through a sealing member 5 in a closed state. The sealing member 5 has elasticity, the upper end of the sealing member is fixed on the upper cover 1, the sealing member 5 is extruded and the lower end of the sealing member abuts against the upper end surface of the cooker body 2 in a cover closing state to ensure the sealing with the end surface of the cooker body 2, and meanwhile, the sealing member 5 is also provided with a water passing channel 18 which vertically penetrates through the sealing member and allows water flow to pass through the water passing channel. In particular, the sealing element 5 comprises corrugated walls 7, at least two corrugated walls 7 connected end to end in sequence form a wave, and the lower end of the lowermost corrugated wall 7 abuts against and seals the pot body 2. From this, the fold wall 7 of a plurality of end to end connection for sealing member 5 is whole when the pressurized warp more regular, guarantees sealed firm, and does benefit to and reduces the resistance when closing the lid, optimizes the feeling of closing the lid, promotes user experience greatly.

Specifically, as shown in fig. 3 and 4, the sealing member 5 is cylindrical and includes a vertical wall 8 and a corrugated wall 7 arranged from top to bottom, wherein the two corrugated walls 7 are arranged up and down, the upper corrugated wall 7 is connected with the vertical wall 8, the lower corrugated wall 7 is provided with a lower opening 13, and the upper end of the vertical wall 8 is provided with an upper opening 12. The two corrugated walls 7 are in V-shaped sawtooth shapes in cross section, the two corrugated walls 7 are same in contour dimension and are arranged in a stacked mode to form a spring-like telescopic structure.

Notably, as shown in fig. 3 and 4, the lowermost corrugated wall 7 includes a first sealing wall section 10 and a second sealing wall section 11, wherein the inclined first sealing wall section 10 is funnel-shaped, the second sealing wall section 11 is disposed at the lower end of the first sealing wall section 10 and extends inward, the lower end surface of the horizontal second sealing wall section 11 is a second sealing surface 14 which is also horizontal, and the outer surface of the first sealing wall section 10 is provided with an inclined first sealing surface 15. Therefore, when the compression amount of the sealing member 5 is small, only the second sealing surface 14 can perform sealing, and when the compression amount is large, the first sealing surface 15 and the second sealing surface 14 are both attached to the upper end surface of the pot body 2 and are sealed together, so that the sealing member 5 can adapt to different compression amounts. Meanwhile, the thickness value of the second sealing wall section 11 is a, and the thickness value of the first sealing wall section 10 is b, wherein a > b, the second sealing wall section 11 with higher strength is obtained, and the circular second sealing wall section 11 is prevented from being pressed into an oval shape and tilting after being closed, so that the sealing is more accurate and firm. In addition, the annular second sealing wall section 11 encloses the lower opening 13 of the water passing channel 18, the cooker body 2 is provided with the lower through hole 6 corresponding to the lower opening 13, the distance between the inner side edge of the second sealing wall section 11 and the hole wall of the lower through hole 6 is c, the value of c is preferably 2.5mm-8mm, the embodiment adopts c as 4mm, which can avoid the inner side edge of the second sealing wall section 11 from being too close to the lower through hole 6, and avoid the sealing element 5 from failing to play a sealing role when the cooker body 2 and the upper cover 1 are dislocated or offset.

In order to fix the sealing member 5, as shown in fig. 3 to 6, the liner 3 of the upper cap 1 is provided with an annular groove 17, and the lower extension pipe 16 of the upper cap 1 extends downward through the annular groove 17, the lower extension pipe 16 is provided with a fixing rib 19 at an upper side of the annular groove 17, and correspondingly, the top end of the vertical wall 8 of the sealing member 5 is provided with an axial limit step 9 protruding toward the outer periphery.
