Description

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

BACKGROUND ART A conventional rice cooker of this type had a configuration as shown in FIG. That is, the control means 2 controls the rice cooking/warming means 3 according to the storage means 1 which stores the rice cooking method for each rice cooking method in the rice cooking menu, and on the other hand, the display driving means 4 controls the display means 5 to notify the user of the rice cooking method. When cooking polished rice, the rice cooking display 6 of the display means 5 lights up, and the rice cooking display 8 of the rice cooking menu display 8 lights up, and the control means 2 stores the information in the storage means 3. The rice cooking and warming means 1 is controlled according to the program for cooking white rice. When the rice cooking is finished and the rice is kept warm, the rice cooking display 6 of the display means 5 disappears and the heat keeping display 7 is turned on. At this time, the white rice display on the rice cooking menu display 8 remained lit. Similarly, in the case of boiled rice and cooked rice, the boiled rice display and the cooked rice display on the rice cooking menu display 8 remained lit when the rice was kept warm.

Problems to be Solved by the Invention In such a conventional configuration, when the warming mode is started, the Okowa display and the Cooking rice display on the rice cooking menu display 8 remain lit, so it is difficult to keep the Okowa and cooked rice warm for a long time. Create the illusion that you can do it. Originally, okowa and cooked rice contain things other than white rice, some of which corrode quickly and therefore cannot be kept warm for long periods of time. When keeping rice warm or cooked rice warm, if the menu is lit,
There was a problem in that it gave the user the illusion that it was okay to keep warm.

The present invention solves these problems,
To provide a rice cooker that does not give a user the illusion that it is okay to keep rice or boiled rice warm.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention is provided with a canceling means for automatically erasing the rice cooking menu display during the warming operation.

Function According to the above configuration, the rice cooking menu display lights up during the rice cooking operation, and the rice cooking menu display turns off when the warming operation starts, allowing the user to keep rice or cooked rice warm for a long time. There will be no more misunderstandings or illusions.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

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 for performing a rice cooking operation, 12 indicates a rice cooking control means for controlling the rice cooking means 11, and 15 indicates two or more types of rice cooking means. This storage means stores the rice cooking method for each rice cooking menu and operates the rice cooking control means 12 according to the information. On the other hand, 13 is a heat retaining means for performing a heat retaining operation;
Reference numeral 4 denotes heat retention control means for controlling the heat retention means 13, and this heat retention control means 14 performs heat retention control in accordance with the heat retention information of the polished rice stored in the storage means 15. 16 is a display means for displaying the rice cooking and warming operations currently being performed; 17;
18 is a display driving means for driving the display means 16, and 18 is a canceling means for instructing the display driving means 17 to turn off the rice cooking menu on the display means 16 when the warming operation is started.

FIG. 2 shows a circuit diagram of the rice cooker. 19 is a commercial power source, and rice cooking means 11
The rice-cooking heater 11a and this rice-cooking heater 11
It is composed of a relay contact 11b and a relay coil 11c, which is a controller of the controller a. 20 is a microcomputer, and this microcomputer 2
0 stores rice cooking methods such as white rice cooking and rice cooking, and accordingly the relay coil 11c is energized and the relay contact 11b is controlled to open and close. As a result, current flows from the commercial power supply 19 to the rice cooking relay 11a, so that the rice cooking heater 1
1a performs a rice cooking operation under energization control. on the other hand,
The microcomputer 20 outputs the content of currently cooking rice to the display means 16. This display means 1
6 is composed of a display board 16a on which a name is printed in advance, a rice cooking LED 16b, a heat retention LED 16c, and a rice cooking menu display 16d. When cooking white rice, rice cooking LED 16b and rice cooking menu display 16d
The white rice display lights up. Similarly, during rice cooking or rice cooking, the rice cooking LED 16b and the rice cooking menu display 16d are lit. The heat retaining means 13 is composed of a heat retaining heater 13a, a triac 13b which is a controller for the heat retaining heater 13a, and a transistor 13c for triac control. When the rice cooking is finished and the heating operation starts, the microcomputer 20 stops the rice cooking control and controls the transistor 13c to turn the triac 13b ON/OFF. As a result, the heat-retaining heater 13a is controlled to be energized, and current flows from the commercial power source 19 to perform the heat-retaining operation. During this warming operation, the rice cooking LED 16b is turned off and the warming LED 16c is turned on, but the rice cooking menu display 16d is automatically turned off.

Effects of the Invention As described above, according to the present invention, when rice cooking or rice cooking is started, the rice cooking menu display turns off when the warming operation starts, allowing the user to perform their own warming control for each rice cooking menu. This will eliminate the possibility of misunderstandings or illusions that appear to be true.
