Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a rice cooker for general household use.

BACKGROUND TECHNOLOGY As shown in FIG. 3, this type of conventional rice cooker displays the name of the rice cooking menu and the rice cooking operation status such as pre-cooking, finished cooking, and additional cooking on a display means 1 comprising a liquid crystal display element. The rice cooking menu and rice cooking operating status were displayed to the user. If you have enough time to cook the rice and let it soak in water naturally, press the pre-cooking skip switch.
I didn't pre-cook it and just cooked it over high heat.

Problems to be Solved by the Invention In such conventional rice cookers, when the pre-cooking skip switch is pressed in any rice cooking menu, pre-cooking is omitted and the rice starts cooking over high heat. However, if a user presses the pre-cooking skip switch when cooking brown rice and skips pre-cooking, brown rice soaks slowly in water and takes a long time to soak, so the cooked brown rice becomes dry and inedible. It had the problem of being stored away.

The present invention has been made to solve these problems, and when cooking two or more types of rice including brown rice while displaying the rice cooking operation display, the present invention prohibits omitting pre-cooking of brown rice and prevents brown rice from being omitted. The purpose of the present invention is to provide a rice cooker that can prevent mistakes in cooking rice.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a pre-cooking omission switch that omits pre-cooking when cooking brown rice. This prevents pre-cooking from being omitted even if you press .

Effect: According to the above configuration, pre-cooking is not omitted when cooking brown rice, so there is no problem of the user omitting pre-cooking when cooking brown rice, resulting in dry brown rice due to insufficient water soaking. It is.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings. FIG. 1 shows a block diagram of a rice cooker according to an embodiment of the present invention, in which reference numeral 11 indicates a rice cooking means consisting of a rice cooking heater control element for performing a rice cooking operation, and 12 indicates a rice cooking menu and a rice cooking state during the rice cooking operation. 13 is a storage means that stores programs for two or more types of rice cooking menus including brown rice; 14 is a display means for displaying the rice cooking operation status such as pre-cooking during the rice cooking operation; LCD driving means; 15 is a pre-cooking omission switch for omitting pre-cooking when cooking other than brown rice; 16;
is a control means for controlling the rice cooking means 11 and the display means 12 according to the switch 15 and the program in the storage means 13.

Fig. 2 shows a block diagram of only the rice cooking means of the same rice cooker, in which 17 is a commercial power supply, and the rice cooking means 11 includes a rice heater 11a, a relay contact 11b serving as a rice heater control element, and The relay 11d is composed of a relay coil 11c, and the relay coil 11c is energized and controlled by the control means 16 according to a rice cooking menu program such as white rice, boiled rice, boiled rice, brown rice, etc. stored in the storage means 13. Relay contact 11
b is controlled to open and close. As a result, the rice cooking heater 11
A current flows from the commercial power source 17 to a to perform the rice cooking operation.

On the other hand, since the control means 16 outputs the rice cooking menu during the rice cooking operation and the rice cooking operation state such as pre-cooking to the liquid crystal driving means 14, the liquid crystal driving means 14 drives the display means 12.

If there is sufficient cooking time, the user can omit pre-cooking; in this case,
If the user presses the pre-cooking omission switch 15, pre-cooking is omitted. In the case of brown rice cooking, if you skip the pre-cooking, the rice will become dry and the cooking will fail.However, when cooking brown rice, even if the user presses the pre-cook omission switch 15, the pre-cooking will not be done. Since it is not omitted, there is no chance of cooking failure resulting in dry brown rice.

Effects of the Invention As described above, according to the present invention, there is a pre-cooking omission switch that omits pre-cooking when cooking rice other than brown rice, and a memory that stores programs for two or more types of rice cooking menus including the pre-cooking omission switch and brown rice. Since a control means is added to control the rice cooking means and the display means consisting of a liquid crystal display element in accordance with the program of the means, pre-cooking will not be omitted even if the user presses the pre-cooking omission switch when cooking brown rice. figure,
Therefore, the problem of dry and inedible brown rice due to insufficient soaking due to pre-cooking is eliminated.
