Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

A first embodiment of the present invention is as follows.

The packing 10 for the electric pressure cooker first includes a body 15 having a ring shape.

For reference, the packing 10 for the electric pressure cooker is made of a material having elasticity such as a rubber material.

The packing 10 for the electric pressure cooker of the present invention is fitted and fixed in a groove (not shown) provided in the inner pot cover 110.

Grooves (not shown) provided in the inner pot cover 110 are also formed in a ring shape, and the grooves are preferably formed in such grooves so as to prevent the packing 10 for the electric pressure cooker from being inserted.

It is preferable that the sealing portion 20 is extended downward from the body 15 and formed integrally with the body 15.

The sealing portion 20 is extended to have a predetermined distance, and the sealing portion 20 also has a ring shape.

The sealing portion 20 prevents the pressure in the inner pot 100 from being generated until the inner pot cover 110 is brought into contact with the upper portion of the inner pot 100 or prevents the inner pot 110 from being separated from the upper portion of the inner pot 100 A gap can be formed between the inner pot 110 and the inner pot 110 to facilitate separation of the inner pot 110 from the inner pot 100.

In the packing (10) for an electric pressure cooker of the present invention, the sealing portion (20) is formed in partial contact with the inner side surface (105) of the inner pot.

As described above, the partial contact between the inner side surface 105 of the inner pot and the closed portion 20 is achieved by a wave or irregularity or protrusion formed in the closed portion 20.

A second embodiment of the present invention is as follows.

The above-described sealing portion 20 is formed to have a wave 30 in the circumferential direction.

A wave (30) is formed in the circumferential direction of the sealing portion (20).

In the wave 30, a valley and a floor are continuously formed.

Therefore, the closed portion 20 does not entirely contact the inner pot 105 of the inner pot, and a non-contact portion is formed.

The inner periphery of the inner pot 105 and the milled portion 20 in which the wave 30 is formed in the circumferential direction are partially in contact with each other.

(1) Contact between the inner pot (100) and the packing (10) when cooking the electric pressure cooker (1) is as follows.

A part of the waveform 30 is expanded outward due to the pressure generated in the inner pot 100 by the packing 10 inserted in the inner pot 100 during cooking.

That is, normally, the valleys 31 which are not in contact with the inner pot 105 are located on the same line as the valley 32 due to the pressure inside the inner pot 100, Lt; / RTI >

Therefore, when cooking the electric pressure cooker 1, the inside of the inner pot 100 is sealed by the packing 10 for electric pressure cooker.

(2) After completion of cooking of the electric pressure cooker 1, the contact between the inner pot 100 and the packing 10 for electric pressure cooker during the warming process is as follows.

After completion of the cooking, the pressure inside the inner pot 10 escapes through the solenoid valve (not shown) and the pressure inside the inner pot 10 becomes low, so that the waveform 30 returns to its original shape again.

Therefore, the inner pot inner side surface 105 and the sealing portion 20 partially contact each other.

That is, only the portion corresponding to the floor 32 of the closed portion is in contact with the inner pot side 105.

Therefore, when the user opens or closes the lid 200, the contact area between the inner pot 105 and the lid 20 is reduced, so that the lid 200 can be easily opened and closed.

A third embodiment of the present invention is as follows.

The above-described sealing portion 20 is formed so as to have the concave and convex portions 40 in the circumferential direction.

Hereinafter, the recesses 41 and the protrusions 42 will be referred to as the portions having different height by the recesses 40 formed in the circumferential direction of the sealing portion 20. FIG.

The recessed portion 41 formed in the sealing portion 20 prevents the sealing portion 20 from contacting the inner pot inner surface 105 in the circumferential direction.

That is, the recessed portion 41 makes partial contact between the shaft portion 20 and the inner pot inner surface 105.

(1) Contact between the inner pot (100) and the sealing portion (20) during cooking of the electric pressure cooker (1) is as follows.

The recesses 41 are expanded outward by the pressure generated in the inner pot 100 by the packing 10 inserted into the inner pot 100 during cooking.

That is, the recessed portion 41, which is not in contact with the inner pot inner surface 105 at the normal time, is positioned in line with the convex portion 42 by the steam pressure inside the inner pot 100, And is in full contact with the inner surface 105.

Therefore, at the time of cooking the electric pressure cooker 1, the inside of the inner pot 100 is sealed by the sealing portion 20.

(2) After completion of cooking of the electric pressure cooker 1, the contact between the inner pot (100) and the sealing portion (20) during the warming process is as follows.

When the steam generated inside the inner pot 100 is discharged through the solenoid valve (not shown) after completion of cooking, the pressure inside the inner pot 100 is lowered.

At this time, the concave portion 41 is returned to the original position, so that only the inner pot inner side surface 105 and the convex portion 42 of the sealing portion 20 are contacted.

That is, the inner pot inner side surface 105 and the sealing portion 20 partially contact each other.

Therefore, when the user opens or closes the lid 200, the area of contact with the inner pot 105 is reduced, so that it can be easily opened and closed.

A fourth embodiment of the present invention is as follows.

The packing (10) for an electric pressure cooker of the present invention further includes an auxiliary closure (50).

The auxiliary sealing portion 50 is extended from the outer wall 25 of the sealing portion to have a predetermined length and thickness.

The auxiliary sealing portion 50 makes surface contact with the upper portion 102 of the inner pot to seal the inner portion of the inner pot 100 when the inner pot cover 110 contacts the upper portion 102 of the inner pot.

At the time when the inner pot cover 110 is separated from the upper pot 102 of the inner pot, the inner pot 100 is first separated from the upper pot 102 of the inner pot.

The length and thickness of the auxiliary sealing portion 50 are preferably smaller than those of the sealing portion 20.

An embodiment of the electric pressure cooker (1) having the packing (10) for the electric pressure cooker of the present invention is as follows.

First, the electric pressure cooker 1 includes an inner pot 100.

The inner pot 100 is located in the main body 300 and the lid 200 is hinged to one side of the main body 300 so that the main body 300 can be opened and closed.

When the lid 200 is completely closed, the inner pot cover 110 is seated on the upper pot 102 of the inner pot.

It is very important that the steam and the vapor pressure inside the inner pot 100 are not leaked to the outside by the electric pressure cooker 1.

A packing 10 for an electric pressure cooker having a ring shape is provided on the inner side surface 115 of the inner pot cover to seal the inner pot 100 of the electric pressure cooker 1 in the inner pot cover 110. [
