It moves to the lower part of the housing along the thread 161 formed on the outer surface of the).

When the moving unit 130 moves to the lower side of the housing, the bottom surface of the stepped portion 131 of the moving unit 130 presses one side of the spring 140 installed inside the housing 160, and the spring 140 is pressurized. The pin 150 is pressed.

Therefore, the elastic force of the spring 140 is variable according to the position where the moving unit 130 is moved along the housing 160.

The pressure pin 150 is opened when the internal pressure of the cooker exceeds the elastic force of the spring at the time of cooking, and the steam inside the cooker introduced through the steam inlet 181 is formed through the steam outlet 162 formed in the housing 160. The pressure pin 150 is discharged to the outside of the pressure regulating device 100, and when the excess internal pressure is discharged, the pressure pin 150 is restored by the elastic force of the spring 140.

After the cooking is finished, the knob knob 200 is rotated from any one of the set pressures to move the position of the moving unit 130 to the upper portion of the housing 160, thereby reducing the elastic force of the spring 140.

When the elastic force of the spring 140 is reduced, the pressure inside the cooker exceeds the elastic force of the spring 140, and steam is discharged. When the knob knob 200 is rotated counterclockwise from the reference position, that is, the moving part ( 130 moves to the top of the housing 160 (see FIG. 4).

The moving part 130 moved to the uppermost part of the housing 160 also moves the flange 121 of the rod pin 120 in close contact with the stepped part 131, so that the pressure pin is coupled to the lower part of the rod pin 120. The 150 is separated from the through hole 163 of the housing 160, and the housing 160 is opened from the closed state to force the steam inside the cooker to be exhausted.

On the other hand, the angle that the knob knob 200 is rotated counterclockwise (see Fig. 5) in order to force the exhaust of the steam inside the cooker does not exceed a certain angle (for example, up to -45 °). If the angle is not limited at the time of reverse rotation, the fourth display unit 313 is rotated, and it is not easy to check whether the maximum pressure is set or the steam is set for forced exhaust.

Therefore, it is also possible to provide a stopper (not shown) between the first display portion 310 and the fourth display portion 313 of the pressure display portion 300 to prevent the knob knob 200 to rotate over a certain angle during the reverse rotation. When the reverse rotation, the upper end surface of the moving unit 130 may be in contact with the bottom surface of the pressure regulating core 110 (see FIG. 4), so that the additional reverse rotation may be limited.

In the above, the present invention has been illustrated and described with respect to certain preferred embodiments. However, the present invention is not limited to the above-described embodiments, and those skilled in the art to which the present invention pertains can vary as many as possible without departing from the spirit of the present invention as set forth in the claims below.
