The present invention provides a rice cooker which comprises an inner pot, an inner lid, and a first elastic seal ring, the inner lid is snapped on the inner pot to enclose a pot cavity, the first elastic seal ring is disposed at the periphery of the inner lid to seal the gap between the inner lid and the inner pot when the inner lid is snapped on the inner pot, the inner lid comprises an inner surface facing the pot cavity and an outer surface disposed opposite to the inner surface, and the inner lid is provided with an exhaust through hole passing through the inner surface and the outer surface. The rice cooker further comprises an exhaust through hole sealing means comprising an elastic sealing disk which is attached on the outer surface of the inner lid and covers the exhaust through hole. When the difference between the internal air pressure and the external air pressure of the pot cavity is less than a first pressure difference, the elastic sealing disk seals the exhaust through hole, and when the difference is greater than the first pressure difference, the elastic sealing disk releases the sealing of the exhaust through hole. |
