Problems solved by technology

[0005] However, if the heat of the heating pot is weakened during the heating 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

[0050] A first embodiment of the present invention will be described below. Figure 1A Shown is a sectional view of an electric rice cooker in the first embodiment of the present invention, Figure 1B It is a block diagram showing the structure related to rice cooker control. The rice cooker of 1st Embodiment of this invention is an electric type IH heating rice cooker. exist Figure 1A and Figure 1B Among them, 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; The heating unit 3 of 2; the cover 4 that is installed on the body 1 as free opening and closing, covering the upper opening of the pot 2; and the bottom surface center of the pot 2, as an example of the pot temperature detection part that detects the temperature of the pot 2 Pot bottom temperature sensor 5; Dispose inside cover 4, control the heating control part 71 of the pot heating action of control heating unit 3 ac...

no. 2 approach 〕

[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] Figure 8 It is a diagram showing the process of stewing rice in which the first control and the fourth control are performed at the same time.

[0091] According t...

no. 3 approach 〕

[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 present invention provides an electrical rice cooker. The electrical rice cooker comprise a cooker accomodated in the inner of the electrical rice cooker, a cover that can open / close freely for covering the opening part on the upside of the cooker, a cooker bottom heating device for heating the cooker bottom, a cooker temperature detecting part for detecting the temperature of the cooker, a heat control part for controlling the cooker heating action of the cooker bottom heating device, a stewing mode input part for inputting one random stewing mode of the stewing modes that includes standard stewing mode and energy saving stewing mode, and a stewing control part for controlling cooker heating device and actualizing the stewing step based on the input stewing mode and the detected temperature. The stewing control part controls the cooker heating device in the soaking step under the circumstances that the stewing input part inputs the energy saving stewing mode to make the detectingtemperature reach the prescribed temperature in prescribed time, after a prescribed time, the heat action of the cooker heating device is stopped by controlling the heat control part.

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 a small fire~", which mainly consists of the soaking process to allow the rice to absorb water, the heating process to instantly increase the temperature in the pot to make it boil, and the process of maintaining the boiling to gelatinize the rice starch into rice. The boiling step is maintained,...
