PURPOSE: A pressure cooker including an integrated safety device is provided to prevent the damage of a safety body as a plate spring of metal materials in which the assemblability is improved surrounds the outer circumference of the safety body and protects the same even when the contact or friction with a safety connecting member is frequently generated. CONSTITUTION: A pressure cooker including an integrated safety device comprises a main body, a cap (5), a fixed case (320), a diaphragm (350), a safety body (340), a non-returning pin, and a safety connecting member. The diaphragm is equipped with a holder unit (350b) on the edge of a hollow hole formed in the inner side of a wing unit which is elastically transformed to upper and lower parts based on the edge fixed according to inner pressures of an accommodating unit. The safety body is connected to the upper part of the diaphragm, is vertically moved along a safety space (320a), and a hollow unit (340a) is formed in the inner side. The non-returning pin is separated and opens a hollow hole (350a) when the pressure in which is greater than a tolerance value is applied. The safety connecting member is hung when the safety body is lifted and restricts the rotation to open the cap. |
