The present invention relates to an insulating pressure cooker fixing device, in particular, to prevent the inner pot from rotating or flowing when the inner pot is inserted into the pressure cooker.

The inner pot fixing device and the peripheral portion of the conventional electric heat pressure cooker is the main body (1), the inner pot (2) formed in the main body (1), the inner pot ( It is composed of a heating portion (3) formed at the lower end of 2) to generate heat, a projection (4) formed on the outer surface of the inner pot (2), and a groove (5) engaged with the projection (4). .

The operation of the inner pot fixing device of the conventional electric thermal pressure cooker configured as described above and the problems thereof will be described below.

As shown in FIG. 1, the inner pot 2 is placed on the heating part 3 formed at the lower end of the conventional electric thermal pressure cooker.

At this time, the fixing device of the inner pot (2) to form a groove (5) to enter into the outer side in contact with the projection 4 and the protrusion 4 formed on the outer surface of the inner pot (2) itself, the projection on the groove (5) Combine (4) to fix the inner pot (2).

However, the inner pot fixing device of the conventional electric insulation rice cooker fixed the inner pot by combining the protrusion formed on the outer surface of the inner pot with the groove formed on the outside contacting the protrusion, but the bottom portion of the inner pot floats in the inner side like the IH type cooker. In the inner pot was a problem that rotates or flows.

Therefore, an object of the present invention is to prevent the inner pot from rotating or flowing in the pressure cooker by forming a plurality of protrusions on the outer circumferential surface of the inner pot inserted into the pressure cooker and forming at least two stoppers on the upper case so that the protrusions are caught. .

The inner pot fixing device and its peripheral portion of the electric thermal pressure cooker of the present invention will be described as shown in FIG.

As shown in FIG. 2 and FIG. 3, the cooker bonte 101, which is the exterior of the electric warming cooker, and the bent portion 102 ', the upper portion of which is bent outward, and the protrusion 104 formed on the outer circumferential surface of the bent portion are integrally formed. The inner pot 192 and the upper case 105 formed on the rice cooker body 101 so that the bent portion is located in the upper portion when the inner pot 102 is inserted into the cooker body 101, and the upper case 105. The stopper 106 formed to be caught by the protrusion 104 so that the inner pot 102 does not flow, and the inner pot 102 formed on the inner pot 102 and fastened with a support member 114 and a bolt to cover the inner pot 102. Lid 108, the inner ring 102 and the inner ring 108 fastening ring 110 for fastening by rotating the rotating body 109, and the inner pot (102) between the inner pot (102) and the inner cover (108) 102, the packing 111 to prevent the pressure inside the escape, and the inner cover 108 on one side so that the pressure inside the inner pot 102 is kept constant The pressure adjusting device 112 and the pressure adjusting device 112 are provided at one side of the inner cover 108 so as to operate mechanically at a pressure higher than the adjusting pressure of the pressure adjusting device 112 when the pressure adjusting device 112 does not operate due to an abnormality. Configured safety device 113.

That is, the inner pot 102 is integrally formed with an upper bent portion 102 ′ of the inner pot and a protrusion 104 formed on the outer circumferential surface of the bent portion.

In addition, the upper case 105 is formed in the cooker body 101 so that the upper bent portion 102 ′ of the inner pot may be placed on the upper case.

The operation and effects of the present invention configured as described above will be described in detail with reference to FIGS. 2 and 3.

As shown in FIG. 2 and FIG. 3, the food is placed in the inner pot 102, and the inner lid 108 covers the upper portion of the inner pot 102, and the inner pot 102 and the inner lid 108 inside the fastening ring 110. The outer circumferential surface of the) is inserted to rotate the rotor 109 to fasten the inner pot 102 and the inner lid 108 with the fastening ring 110.

Then, when the operation key is pressed on the operation unit 107, the heating unit 103 is heated by the control of the microcomputer to heat the inner pot 102.

At this time, when the inner pot 102 is heated, the inside of the inner pot 102 rises in temperature to generate steam and is sealed by the packing 111 provided between the inner pot 102 and the inner lid 108 and thus the inner pot ( The internal pressure of 102 rises.

When the inside of the inner pot 102 reaches a predetermined pressure, the inner lid 108 is discharged to the atmosphere by the pressure adjusting device 112 provided at one side to the atmosphere of the inner pot 102 to the inner pot 102. ) Keep the internal pressure constant.

However, when an abnormality occurs in the pressure adjusting device 112, the safety device 113 is provided on one side of the inner cover 108 so as to operate mechanically at a pressure higher than the adjusting pressure of the pressure adjusting device 112. Promote.

And Figure 3 is the inner pot 102, a plurality of protrusions 104 formed on the outer peripheral surface of the inner pot 102 and the inner pot 102 is formed on the upper bent portion 102 'and the outer peripheral surface of the bent portion of the inner pot The protrusion 104 is integrally formed.

In addition, the upper case 105 is formed in the cooker body 101 so that the upper bent portion 102 ′ of the inner pot may be placed on the upper case, and the stopper 106 is formed on the upper case 105 to form the inner pot. Insert 102 into the pressure cooker.

In this case, when the inner pot 102 inserted into the pressure cooker rotates in the clockwise direction, the inner pot 102 is formed by the stopper 106-1 formed on the protrusion 104 and the upper case 105 formed on the outer circumferential surface of the inner pot 102. When the inner pot 102 rotates counterclockwise, the inner pot 102 is fixed by the protrusion 104 and the stopper 106-2.

In consideration of the orientation of the inner pot 102 fixed in this way, the stoppers 106 formed on the upper case 105 are provided with at least two or more.

And the height of the stopper 9106 is the same as the height of the inner pot 102 when the inner pot 102 is placed on the upper case 105 to facilitate fastening with the inner lid 108.

As described above, the present invention forms an at least two or more stoppers on the upper case and the plurality of protrusions formed on the outer circumferential surface of the inner pot inserted into the pressure cooker, thereby preventing the protrusion from being caught by the stopper to rotate or flow.
