Abstract

The invention provides a pressure cooker. The pressure cooker has a pressure valve (13) which closes and opens a steam ventilation hole (131) communicating the internal of a pot (10) and a cover body (11), and a pressure valve close-open part (19) which switches between an open state and a close state of the steam exhaust hole (131) by the pressure valuve (13); besides, the pressure cooker also has a control portion which controls a heating device and the pressure valuve open-close part (19) in order to perform cooking process including a heating process and a boiling maintenance process. Besides, the control part controls the open-close part (19) of the pressure valve in the boiling maintenance process in order to reduce pressure inside the pot (10), and the pressure reduction speed of the pressure reduction amount per unit time is variable.

Description

technical field [0001] The present invention relates to a pressure rice cooker that cooks delicious rice in a short time by putting the inside of a pot into a pressurized state to cook rice. Background technique [0002] As a recent pressure rice cooker, a so-called IH rice cooker that heats a pot with water and rice by heating it with eddy current from an induction heating coil has become mainstream, and since this is a pot Due to the self-heating structure, the rice located in the area close to the inner wall of the pot will be fully heated, while the rice farther from the inner wall, from the center to the upper center of the pot, will be insufficiently heated, which is prone to uneven cooking. Structure. [0003] Therefore, Japanese Patent Application Laid-Open No. 2004-081824 proposes a pressure rice cooker capable of cooking rice evenly and making the upper surface of the cooked rice flat to obtain a visually delicious effect. [0004] This pressure rice cooker has: ...
