ELECTRIC RICE PRESSURE COOKER AND PRESSURE COOKER WITHOUT A RUBBER PACKING

摘要

The present invention relates to an electric rice pressure cooker without a rubber packing, and more particularly, to an electric rice pressure cooker including a main body case having an open top, an inner pot installed inside the main body case, and a cover hinge-coupled to the main body case and disposed to cover the open top of the main body case, wherein the inner pot has a plurality of flange portions provided on a top portion thereof at certain intervals apart along a circumferential direction and has a tapered sloped surface formed on the top end thereof, and the cover comprises: a sealing member having a circular hole formed in the center thereof, being seated on the inner pot, and having a bottom surface that is seated on and contacts the inner pot and is formed to correspond to the top end of the inner pot; and an inner cover provided with a receiving space therein in which the sealing member can move vertically, the inner surface of the receiving space being configured to maintain a tight seal with the peripheral end portion of the sealing member. The sloped surface of the inner pot is tapered toward the inside, the sealing member is provided with a bent portion so as to contact the sloped surface of the inner pot and the inner surface of the inner cover, and a part of the bent portion contacting the sloped surface is formed as a sealing surface corresponding in shape to the sloped surface, so that steam generated during cooking passes through the circular hole and presses the sealing member downward to maintain a tight seal with the inner pot.
