Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a rice cooker that can deliciously cook germinated rice in addition to polished rice.

[Prior art]

Recently, interest in healthy food has increased, and more and more people are regularly using germ rice, which contains more vitamins and minerals than self-study rice. When rice is cooked with a rice cooker that automatically performs each step of the rice shading process, there is a drawback that there is insufficient time for additional cooking during the shading process, leaving the rice with cores and making it feel hard.

[Summary of the invention]

The present invention has been made in order to eliminate the above-mentioned nine conventional drawbacks.LJ) In a rice cooker that automatically performs each process of preheating, rice cooking, and shading, there is a germ rice cooking mode in addition to the white rice cooking mode. To provide a rice cooker which can cook germ rice deliciously without any cores by increasing the additional cooking power during the rice shaving process in the germ rice cooking mode, in the white rice cooking mode, and intensifying the additional cooking power during the rice shaving process. The purpose is to

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows the configuration of a rice cooker according to this embodiment, and 1 is a pot;
2 is a heating element that heats the pot 1 from the bottom, 3 is a mode selection switch that selects a rice cooking mode, 4 is a rice cooking mode selection means, 5 is an additional cooking power determining means, and 6 is a heating amount control means. Based on the output of the rice cooking mode selection means 4 which receives the signal from the mode selection switch 3, the additional cooking power determining means 5 determines the additional cooking power for the white rice cooking mode and germ rice cooking mode, and according to this determination, The heating body 2 is controlled by the heating amount control means 6.

Figure 2 is a cross-sectional view of the rice cooker, with reference numeral 11 an outer box housing pot 1 inside, 12 a lid of pot 1, and 10 a heat shield plate provided at the bottom of outer box 11. A heating element 2 consisting of an electric heater is provided on the upper part of the heating element 10 .

Reference numeral 9 denotes a pot bottom temperature detector provided at the center of the heat shield plate 10 so as to be in contact with the bottom of the pot 1. Reference numeral 7 denotes an operation panel attached to the outer surface of the lower part of the outer box 11. A mode selection switch 3 is provided on the outer surface of the operation panel 7, and a control device 8 is provided inside the operation panel 7.

Figure 3 is an electrical connection diagram of the rice cooker, 15 is the input circuit 16,
Memory 17, CPU 18 and output circuit 19 are included in M-f.
It is a microcomputer that uses Reference numeral 13 denotes a polished rice/germ rice cooking mode selection circuit, which is composed of a mode selection switch 3 and a resistor 14, and its output is connected to an input terminal 20 of an input circuit 16.

An output terminal 21 of the output circuit 19 is connected to a transistor 23 via a resistor 22, and the transistor 23 is connected to a relay 24.
It is connected to the VC power supply terminal 26 via. The contacts of the relay 24 are connected to a commercial frequency power source 27 via the heating element 2 . 25 is a VSS power supply terminal of the mode selection circuit 13 and the microcomputer 15.

Next, the operation of the above device will be explained using FIG. 4. Fourth
The figure is a flowchart showing a reheating power selection program during the unevenness process, which is stored in the memory 17. first,
When cooking white rice, when the mode selection switch 3 is short-circuited, the input terminal 20 becomes High, the process proceeds from step 28 to step 29, and after entering the shading process, additional cooking is performed using additional cooking power WhV/). Generally, when the rice cooking process is finished, the rice is steamed for a predetermined period of time, but if the rice is further cooked for a predetermined period of time using a predetermined amount of electricity during this steaming process, the excess water in the pot 1 will evaporate and the rice will be smoothed. It is known that there is. The above-mentioned additional cooking power □1 power WA6M is set to the power suitable for white rice. This additional cooking is carried out by the heating element 2 heating the pot 1 under the control of a control section comprising an output circuit 19, a resistor 22, a transformer 23, and a relay 24. Next, when cooking germ rice, when the mode selection switch 3 is released, the input terminal 20 becomes Low.
The process proceeds from step 28 to step 30, and after entering the unevenness process, additional cooking is performed using the additional cooking power wB board. This additional cooking power WnVJ should be set to a power suitable for embryonic rice, and set to be stronger than the additional cooking power wA for white rice (WB>
WA) Cook the germ rice so that no core remains.

In the above embodiment, the heating body 2 is driven by electric energy, but it may be driven by other energy such as gas. For example, in a rice cooker that uses gas as energy, a burner may be used as the heating element 2, and a valve for regulating the amount of gas may be used instead of the relay 24.

〔Effect of the invention〕

As described above, according to the present invention, in addition to the white rice cooking mode, there is provided a germ rice cooking mode, and in the germ rice cooking mode, the additional cooking power during rice shaving is made stronger than in the white rice cooking mode. You can easily and deliciously cook not only white rice but also germinated rice.
