As a result, contact between the upper surface of the plunger 39 and the core 37 is prevented, thereby preventing the occurrence of impact sound.

Referring to the operation of the present invention having the configuration as described above in detail.

When the closing operation signal of the control unit (not shown) is input, the valve seat 40 is maintained by shielding the orifice 11 of the support member 10 by the force of the elastic body 38 to prevent the discharge of steam. When the opening operation signal is input from the control unit, the plunger 39 is attached to the core 37 by the magnetic force generated by the coil unit 35, so that the valve seat 40 is raised, and accordingly The path will be formed.

Accordingly, the steam is discharged to the outside while sequentially passing through the orifice 11 and the discharge passage 12 of the support member 10 and the steam movement path 21 of the steam discharge pipe 20.

Meanwhile, in the present invention, when the steam pressure inside the inner pot (see 101 in FIG. 1) in the closed state exceeds or falls below 1 kg per 1 cm 3 of the reference value, the valve seat 40 is elevated by the steam pressure.

For example, when the internal pressure of the pressure cooker is 1.2Kg per 1 cm 3, the steam pressure overcomes the elasticity of the elastic body 38 due to the pressure rise of the inner pot, and consequently the valve seat 40 and the plunger 39. Is pushed up due to steam pressure.

That is, when the pressure inside the inner pot rises to 1 Kg or more per 1 cm 3, which is a reference value, the steam pressure acts on the bottom surface of the valve seat 40 through the orifice 11 to push up. At this time, since the valve seat 40 is provided with a predetermined gap with the positioning guide 15 of the support member 10, since the interference phenomenon due to friction with the positioning guide 15 does not occur during the upward movement, the smooth upward movement This becomes possible.

Therefore, the orifice 11 is opened by the upward movement of the valve seat 40 to form a movement path of the steam as described above, thereby automatically discharging the steam to perform the function of the safety valve.

On the other hand, when the steam pressure inside the inner pot (see 101 in FIG. 1) falls below 1 Kg per 1 cm3 of the reference value, the valve seat 40 is lowered by the elastic support force of the elastic body 38 while the positioning guide ( 15) to shield the orifice (11).

For example, when the internal pressure of the pressure cooker is 0.6 ~ 0.9Kg per 1 cm 3 actuated by the elastic bearing force of the elastic body 38 designed to withstand the pressure load of 1 kg per 1 cm 3, the valve seat 40 is lowered Done.

At this time, the valve seat 40 is provided with a gap with the positioning guide 15 of the support member 10 as described above, so that the interference phenomenon due to friction does not occur, the lowering operation is easily performed.

Accordingly, the valve seat 40 is inserted into the positioning guide 15 to shield the orifice 11, thereby blocking the discharge of steam, thereby increasing the pressure of the inner pot.

In particular, the elastic sealing damper 50 at the opening and closing of the orifice 11 according to the lifting operation of the plunger 39 and the valve seat 40 as described above has an outer circumferential fitting portion 51 having one end thereof with the supporting member 10. Since the inner circumferential fitting portion 53 coupled to the solenoid 30 and the other end is connected to the lower portion of the plunger 39, consequently, a closed space is formed between the support member 10 and the plunger 39 to form a vapor. The leakage can be blocked, and in addition, the damping protrusion 55 contacts the bottom surface of the solenoid 30 first during the upward movement of the plunger 39 to generate a predetermined damping force, and at the same time, a stopper acts, resulting in the plunger. It is possible to prevent the upper surface of the 39 from contacting one side of the core 37 to prevent the occurrence of impact sound.

On the other hand, the present invention is not limited to the described embodiments, it is apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to belong to the claims of the present invention.
