The thickness of the covering 133 is 0.2 to 1.5mm, and more preferably 0.3 to 0.8mm. This solution may facilitate the manufacturing of the wrapping layer 133 and may reduce the cost.

To further improve the sealing at the pan mouth, in one embodiment, as shown in fig. 2, the inner pan further comprises a sealing part 140, and the sealing part 140 is disposed at the junction of the first end wall 133b of the wrapping layer 133 and the upper surface of the first wall 131 to close the gap between the first end wall 133b and the upper surface, preventing moisture from entering the interior of the pan mouth to cause rusting. In the illustrated embodiment, the sealing portion 140 is configured as an annular sheet and is disposed between the first end wall 133b and the upper surface. Preferably, the sealing part 140 is made of a flexible material such as rubber, silicon, etc. to improve sealing effect. In other embodiments, the sealing portion 140 may be formed between the first end wall 133b and the upper surface by a welding process such as brazing.

In another preferred embodiment, as shown in FIG. 3, the first end wall 133b further includes a flange 141 extending downwardly from the first end wall 133b. The flange 141 is provided on the opposite side of the first end wall 133b from the wrapping body 133 a. That is, the burring 141 is disposed substantially perpendicularly to the first end wall 133b and substantially parallel to the wrapping body 133 a. The flange 141 is configured as a seal 140. The flange 141 is integral with the first end wall 133b. In this embodiment, the flange 141 can cover the gap between the first end wall 133b and the upper surface of the first wall 131 to close the gap, thereby preventing water vapor from entering the interior of the pot mouth and causing rusting. Preferably, a circle of step part 142 is arranged on the upper surface of the first wall 131 near the inner cavity of the inner pot, and the flange 141 is arranged on the step part 142, so that the inner surface of the inner pot can be smoother.

Further, by providing the seal portion 140 at the junction of the first end wall 133b of the wrapping layer 133 and the upper surface of the first wall 131 to close the gap between the first end wall 133b and the upper surface, it is possible to prevent moisture from entering the gap of the pot mouth portion to cause rusting.

A method of manufacturing the inner pot 100 for a cooking appliance according to the present invention will be briefly described below. Wherein the first wall 131 of the inner pot 100, the support ring 132 and the wrapping layer 133 may be separately manufactured and then assembled together. Wherein the first wall 131 is manufactured, that is, the inner pot 100 is manufactured, that is, when the inner pot 100 is manufactured, the first wall 131 is naturally manufactured.

The manufacture of the inner pot 100 will be briefly described first. As described above, the inner pot 100 may be made of aluminum or an aluminum alloy material. The inner pot 100 having the first wall 131 may be preliminarily formed using a drawing or casting method in the manufacturing process. Then, the step of the pan opening portion 130 (i.e., the joint between the thickened portion 131a and the other portion of the sidewall 120) can be machined as required so as to eliminate subsequent poor edge covering caused by product deformation, and improve the subsequent qualified rate of edge covering, thereby improving the effects of edge covering and sealing. After the inner pot 100 is preliminarily molded, the sealing part 140 may be placed on the upper surface of the first wall 131.

The support ring 132 may be produced by rolling a strip base material such as iron or copper, and then performing rust prevention. The rolling is a forming method for bending iron, copper and other strips into a closed circular ring. The thickness of the strip is preferably 1 to 3mm to facilitate rolling and assembly. After the edge rolling treatment, two ends of the circular ring do not need to be welded, but a certain opening is reserved, and as described above, the scheme can enable the supporting ring 132 to be more adaptive to the size fluctuation of the inner layer side wall 120 and the outer layer wrapping layer 133, so that the edge wrapping quality can be improved, and the poor edge wrapping is reduced. In order to improve the strength of the support ring 132 and facilitate the rolling and assembling of the support ring 132, two 1-3 mm strips can be stacked in the actual manufacturing process.

For the manufacture of the wrapping 133, stainless steel or stainless iron material may be used. In a preferred embodiment, the sheet stock may be stretch-formed to form a primary wrapping 133, which may then be polished (sanded) as desired. In another preferred embodiment, a strip of stainless steel or stainless iron may be used for the rounding process, and after the rounding process, the two ends of the ring are welded and polished (sanded). The second embodiment is preferable, and the cost can be reduced. The welding process can be laser welding or argon arc welding. After the initial formation of the wrapping layer 133, one end of the wrapping layer 133 may be hemmed 141 to form the first end wall 133b. As shown in fig. 5, in order to facilitate the subsequent assembly step, the second end wall 133c of the wrapping layer 133 at the lower end may be pre-flanged 141 first, that is, the second end wall 133c is not bent to be perpendicular to the wrapping body 133a, and may be bent to form a certain inclination angle with the wrapping body 133a, for example, about 45 degrees, and then bent to be in place when being assembled on the inner pot 100.

Finally, the formed layers are assembled, and with reference to fig. 5, the formed support ring 132 is placed in the formed wrapping layer 133 in advance, so that the support ring is tightly attached to the wrapping body 133a of the wrapping layer 133, and then the support ring 132 and the wrapping layer 133 are transversely pressed into the first wall 131 of the inner pot 100 from the radial outer side of the pot opening 130 as a whole, so that the first end wall 133b is pressed on the sealing part 140 to form sealing. Finally, the second end wall 133c of the wrapping layer 133 at the lower end is flanged 141 to extend substantially perpendicular to the wrapping body 133a and to catch on the step, i.e., the lower edge of the support ring 132 and the thickened portion 131 a.

It will be appreciated that in other embodiments not shown, the first end wall 133b of the surround and the upper surface of the first wall 131 may also be brazed directly together to form a seal therebetween.

For the pot opening part shown in fig. 3, the molding is similar to the above except for the addition step of the sealing part 140. In the adding step of the sealing portion 140, the first end wall 133b and the flange 141 are tightly attached to the first wall 131 and the step portion 142 thereof, and the first end wall 133b and the flange 141 are tightly fitted to the first wall 131 and the step portion 142 thereof by extruding and deforming the upper end plane of the first wall 131, so that the assembly is realized and the sealing effect is achieved.

It should be appreciated that the above embodiment is only one embodiment of manufacturing the inner pot 100, and that various steps are not necessary, and one or more of the steps may be added or subtracted as desired; in addition, the sequence of each step is not necessarily fixed, and the sequence of operations can be adjusted according to requirements.
