Electrical rice cooker

Abstract

The invention provides an electric rice cooker. The rice cooker has a pot housed inside the rice cooker body, an openable lid covering the upper opening of the pot, a bottom heating device for heating the bottom of the pot, a pot temperature detection unit for detecting the temperature of the pot, and a pot bottom control unit. The heating control part of the pot heating operation of the heating device, the rice stewing mode input part inputting any one of the rice stewing modes including the standard rice stewing mode and the energy-saving rice stewing mode, and the stewing rice mode input part according to the input. The rice mode and the detected temperature control the pot heating device to implement the rice cooking process. When the stewed rice control unit inputs the energy-saving stewed rice mode from the stewed rice mode input unit, in the soaking process, the pot heating device is controlled so that the detected temperature reaches a prescribed temperature within a prescribed time; after the prescribed time, The heating control unit is controlled to stop the heating operation of the pan heating device.

Description

technical field [0001] The invention relates to an electric rice cooker mainly used for household use. Background technique [0002] There has been a saying in Japan since the Edo period: "Start a small fire and then a big fire, don't let the child cry." It means that if you want to simmer delicious rice, you have to use high heat to boil it in one breath, and it is best to simmer with almost overflowing firepower. [0003] In today's computer-controlled rice cookers for home use, a computer is built in, and the standard cooking sequence is set to the level of firepower to stew white rice into delicious rice. The general rice stewing process follows the folk tradition of "starting with a small fire~", which mainly consists of the soaking process of letting the rice absorb water, the stewing process of instantly raising the temperature in the pot to make it boil, and maintaining the boiling to make the starch of the rice gelatinize into rice The boiling operation is maintai...

AI Technical Summary

Problems solved by technology

[0005] However, if the heat of the heating pot is weakened during the stewing process and the boiling process, the surface of the rice grains will be deformed, resulting in insufficient gelatinization, and the taste of the rice will naturally be greatly reduced

In addition, if the time of the soaking process is prolonged, the cooking time will undoubtedly be extended

Furthermore, if one does not want to prolong the time of stewing rice with an electric rice cooker, control the total power consumption, and not reduce the taste of rice, then the user must pre-soak the rice in water for more than 1 hour before stewing the rice. To solve, it takes a lot of work
