Claims

[Scope of utility model registration request]

A pressure-sensing floating body 10 that can be raised and lowered is attached to one side of the peripheral edge of the top wall 7 of the lid 3, and a protrusion 12 for locking the operating plate is provided at the lower end of the floating body 10. A horizontally movable operating plate 20 is attached to one side in a penetrating state, and a lid opening/closing operating lever 22 is connected to the outer end of the operating plate 20 with a pin 23, and a stopper 26 extending downward is provided. A stopper guide groove 28 is provided on the upper surface of the handle 8 attached to one side of the pot body 2, and is formed of a stopper retaining groove 29 and a stopper relief groove 30 following the stopper guide groove 28.
The tip of the stopper 26 is fitted into the pressure cooker 1.
When the internal pressure becomes higher than atmospheric pressure, the pressure-sensing floating body 10 rises and is held so that the convex portion 12 at its lower end touches the inner end of the actuating plate 20, and the stopper 26 of the actuating plate 20 moves into the guide groove 28. By being positioned in the stopper retaining groove 29, the lid opening/closing operation lever 22 is locked, and when the internal pressure of the pressure cooker 1 becomes lower than atmospheric pressure, the pressure sensing floating body 10 descends and its convex portion 12 touches the operating plate 2. , 0, and when the lever 22 is operated in this state, the actuating plate 20 and the stopper 26 move, and the stoppers 2 and 6
- From the stopper engagement groove 29 to the stopper release groove 3
A pressure cooker safety device that is designed to shift to zero.
