Background Technology Rice cookers typically have a steam outlet on the pot body. Higher pressure inside the pot helps improve cooking results and speed. Therefore, a steam valve is usually installed at the steam outlet to maintain pressure and prevent overflow. Chinese Patent CN107440540A discloses a steam valve for a rice cooker and a rice cooker. The steam valve includes a valve seat, a valve cover that seals and engages with the valve seat, a valve body, and a valve core disposed between the valve seat and the valve cover. The valve seat has an air inlet, the valve cover has an air outlet, and an exhaust chamber is formed between the valve cover and the valve seat. The valve body has a valve cavity communicating with the air inlet and the exhaust chamber. A partition protrudes from the inner wall of the valve body, and a valve hole is formed on the partition. The valve core is located in the space above the partition in the valve cavity and is used to close the valve hole when engaging with the upper surface of the partition, and to open the valve hole when disengaging from the upper surface of the partition. This rice cooker steam valve maintains a "micro-pressure" effect on the rice cooker body during cooking.
