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 cook

[0050] A first embodiment of the present invention will be described below. FIG. 1A is a sectional view of an electric rice cooker according to the first embodiment of the present invention, and FIG. 1B is a block diagram showing a configuration related to the control of the electric rice cooker. The rice cooker of 1st Embodiment of this invention is an electric type IH heating rice cooker. In FIGS. 1A and 1B , the electric rice cooker in the first embodiment has: a pot 2 that is used to hold rice and water inside the body 1 and is detachably accommodated; A heating unit 3 used to heat the pot 2; a cover 4 that is installed on the body 1 to be freely openable and covers the upper opening of the pot 2; a pot that is externally connected to the center of the bottom surface of the pot 2 and used as a pot for detecting the temperature of the pot 2 Bottom temperature sensor 5, which is an example of the temperature detection part; is arranged inside the cover 4, and controls the h...

[0088] Next, a rice cooker according to a second embodiment of the present invention will be described. The electric rice cooker according to the second embodiment of the present invention performs at least one of the fourth and fifth controls described below in the case of inputting the energy-saving rice stewing mode, instead of the second and third controls, which is the same as Differences from the first embodiment. Other aspects are the same as those of the first embodiment, and will not be repeated here.

[0089] In the boiling maintenance process C, the fourth control not only increases the heating amount per unit time of the heating unit 3, but also reduces the temperature of the pot 2 when the boiling maintenance process C ends, compared with the case of entering the standard rice stewing mode.

[0090] Fig. 8 is a diagram showing a step of stewing rice in which the first control and the fourth control are performed simultaneously.

[0091] According to the fourth c...

[0099] Next, a rice cooker according to a third embodiment of the present invention will be described. The rice cooker according to the third embodiment of the present invention further includes pre-soaking input buttons 62f and 62g as an example of the pre-soaking input unit. The above-mentioned sixth control or seventh control is different from the rice cooker of the first embodiment. Other aspects are the same as those of the first embodiment, and will not be repeated here.

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...
