Embodiment Construction

[0021] specific example

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] In the drawings: 1. Support body; 2. Flange portion of support body; 3. Flange portion of pot mouth; 4. Rivet; 5. Circle body.

[0024] Such as Figures 1 to 4 As shown, the inner pot of the pressure cooker includes a pot wall and a pot bottom. The pot wall and the pot bottom form a concave container with an opening. Outwardly protruding support body 1, the cross section of support body 1 is Type, the outer diameter of which is formed is larger than the outer diameter of the pot mouth. The above-mentioned supporting bodies 1 are distributed on the pot wall by several ones, and the top is close to the bottom of the flange portion 3 of the pot mouth. The supporting body 1 is riveted on the outer wall of the pot by the rivet 4 to ensure that the supporting body 1 is fastened on the pot wall. The supporting body 1 guides the force rec...
