し蒸気抜筒（１９）を介して大気中に放出する。In the normal state shown in FIG. 1, when the heating coil (4) is energized and an eddy current is generated in the inner pot (5),
The inner pot (5) itself generates heat and heats water and rice. The pressure in the inner pan (5) rises with the heating, and the pressure becomes 1.1 kgf.
When the pressure reaches / cm 2 , the steam is released from the steam vent valve (44) and released to the atmosphere via the steam vent cylinder (19).

する。The pushing force of the lid (14) is increased by the reinforcing plate (2).
1) Since one side is pivotally supported by the rice cooker body (1), the lid (14) is inclined and pushed up in such a manner that the lock release button (10) side is greatly opened.
The pivot position moves to the pivot side of the lid (14) as shown in FIG.

The whole upper part of 3) is slightly moved to the unlock button (10) side, and the plate (A) extended to the hooks (37) and (37) as shown in FIG. The hooking portions (37) and (37) and the stoppers (8) and (8) are firmly hooked with each other because they are slightly inclined with respect to them.

4) When it is necessary to open the pressure release button (31) against the return spring (32), the pressure responsive valve (45) is pressed via the transmission mechanism (25) by depressing the pressure release button (31).
The pressure in the inner pot (5) can be released by bringing the inside of the inner pot (5) into communication with the atmosphere by the pressure responsive valve.

である。Further, since the supporting position of the locking plate is changed by the lifting of the inner lid with the rise in pressure and the locking portion is locked to the stopper, the locking portion and the stopper can be connected without using any special parts. The degree of the hanging state can be changed. This is effective when designing many types of electric rice cookers in which the pressure in the inner pot is changed using the same pressure movable mechanism.
【００４０】さらに、係止板はＬ形として上部に軸支部

設けたことから、設計時に長孔の大きさ或は長孔と掛止
部までの長さを変えることにより簡単に掛止部とストッ
パーとの掛止度合を変えることができる。Further, since the locking plate has an L-shape, a long hole serving as a shaft support portion is provided at an upper portion, and a hook portion for hooking to a stopper is provided at a lower portion. By changing the length to the hook, the degree of hooking between the hook and the stopper can be easily changed.
【００４１】このことは設定された圧力値が低い場合に
は長孔を小さく或は長孔と掛止部までの長さを短くする
ことにより可能となる。This can be achieved by reducing the length of the long hole or shortening the length between the long hole and the hook when the set pressure value is low.
