<P>PROBLEM TO BE SOLVED: To provide a pressure rice cooker that eliminates uneven rice cooking by preventing uneven cooking from occurring during a start-up heating process, and improving heat transfer during a boiling process. <P>SOLUTION: The pressure rice cooker includes: a pressure valve 13 for blocking a communication area between a pot 10 and the outside air; a pressure valve opening mechanism 19 attached to the pressure valve, and for forcibly opening the pressure valve from a closed state; and a control means 30 for controlling the heat amount of a heating means, and controlling the opening and closing of the pressure valve by the pressure valve opening mechanism. The pressure rice cooker cooks rice by applying pressure during a start-up heating process among a series of rice cooking processes. The control means controls the pressure valve opening mechanism to forcibly open the pressure valve so that the inner pressure of the pot pressurized during the start-up heating process is immediately reduced by at least 0.1 atmospheric pressure or higher, thereby causing an immediate pressure change in the pot to generate a convention flow to agitate the object to be cooked in the pot. <P>COPYRIGHT: (C)2013,JPO&INPIT |
