Abstract

This rice cooker is equipped with a pot to house water and rice, a heating means, a pressure valve to make the inside of the pot communicate with the outside air or cut off, and a control means for the heating means and the pressure valve. The rice to be cooked is processed by a starting-up process to rapidly heat rice and then a boiling keeping process wherein the rice to be cooked is heated by the heating means when the pressure valve is open.The invention provides a rice cooker in which rice can be sufficiently agitated during boiling and uniformly cooked, and the upper face of cooked rice is flat causing visual artistic effect after rice is completely cooked.

Description

technical field [0001] The present invention relates to a pressure-type rice cooker which cooks rice by keeping the inside of a pot under pressure, thereby cooking delicious rice in a short time. Background technique [0002] The pressure rice cooker usually cooks the rice through the following processes, even if the rice absorbs water in the pot, after the rice absorbs water, the heating mechanism is in a full power state to rapidly heat and heat up, and finally reach the boiling state. In the above process, the pressurized pot maintains the boiling state to continue the boiling maintaining process of cooking rice, and the steaming and stewing process of steaming rice after the boiling maintaining process is completed. [0003] The special feature of this rice cooker is that when cooking rice, the pressure inside the pot is increased especially before or during boiling, and the water soaks the rice grains in a short time under the synergistic effect of heating and pressure,...
