構成している。Also in rice cookers, it is known that the aluminum base of the inner pot is coated with fluorine resin.
Is a square aluminum inner pot made by coating a thin aluminum substrate with fluororesin in advance and pressing it. Secondly, it is used for heating pressure, and a thick aluminum substrate is coated with fluorocarbon resin in advance.
A round inner pot with a single-stage flange is formed by pressing.

から困難であった。In order to solve this problem, a thicker inner pot is considered as the above-mentioned second conventional apparatus. In the second conventional apparatus, the aluminum base is coated with a fluororesin and then pressed. Since the aluminum base is thick, there is a problem that the fluororesin layer is damaged during the press work. For example, performing press work with a special shape on the kettle or the peripheral part damages the fluororesin layer. It was difficult.

ある。The rice cooker according to the present invention is detachably provided in an outer pot,
An inner pot having a first horizontal portion and a second horizontal portion that horizontally extend in two stages in the peripheral portion, and is provided so as to cover the opening of the inner pot, and the first lid in a state of covering the inner lid opening. A lid body having an inner lid that is pressed against the horizontal portion of and a packing that is pressed against the second horizontal portion, the inner pot having an aluminum base of 2 mm or more, and a fluororesin provided on the inner wall of the aluminum base. The aluminum base is coated with the fluororesin before pressing into the inner pot, and the radius of curvature of the bending contour forming the both horizontal portions in the peripheral portion of the inner pot is set to It is made more than the plate thickness.

のが得られる効果がある。As described above, according to the present invention, since the inner pot is thickened,
The rice is cooked deliciously, and the aluminum substrate is coated before pressing the fluorine resin into a pot shape, so a uniform layer of fluorine resin can be obtained, and in addition, there are two horizontal stages provided in the peripheral portion of the inner pot. Since the radius of curvature of the bent outer shape that constitutes the part is greater than the plate thickness of the inner pot, the bending becomes soft, and a thick aluminum substrate provided with fluororesin is pressed to have two horizontal parts in the peripheral part. Even so, it is possible to prevent the fluororesin layer from being damaged, and it is possible to obtain an excellent corrosion resistance.
