Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a rice cooker equipped with display means for displaying a plurality of rice cooking processes.

BACKGROUND TECHNOLOGY As shown in Fig. 3, in this type of conventional rice cooker, multiple process names during rice cooking, ``pre-cooking,''``cooking,'' and ``additional cooking,'' are printed in advance on the display section 1. Furthermore, light emitting diodes (hereinafter referred to as LEDs) 3 and 5 were provided above the plurality of process names.

During the pre-cooking process, the pre-cooking LED 3 placed above the process name 2 of "pre-cook" lights up, and during the cooking process, the pre-cooking LED 3 turns off,
The cooking LED 5 arranged above the process name 4 of "cooking" lights up. Furthermore, when the cooking process is completed and the process moves on to the additional cooking process, the
The LED 5 goes out, and the additional cooking LED 7 placed above the "additional cooking" process name 6 lights up. In this way, each
LEDs 3, 5, and 7 were lit in accordance with each step of the rice cooking operation being executed to inform the user which step of the rice cooking operation was being performed.

Problems to be Solved by the Invention In such a conventional configuration, the rice cooking process was notified by lighting each LED 3, 5, and 7, so in a bright place, it was difficult to see which LED 3, 5, and 7 were lit. The problem was that it was difficult to see and it was difficult to check the process during rice cooking. especially,
When checking the process from a remote location, use LED3,
The lack of light intensity in Nos. 5 and 7 made it even more difficult to confirm the process.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, it is an object of the present invention to enable process confirmation to be easily performed from a distance even in a bright place.

Means for Solving the Problems In order to achieve the above object, the present invention provides a rice cooking means for performing a rice cooking operation, a display means consisting of a liquid crystal display element, a control means for controlling the rice cooking means, and a rice cooking means for controlling the rice cooking means. a liquid crystal driving means for displaying only the name of the rice cooking process in progress from among the plurality of rice cooking processes to be carried out; The rice cooking process name and the process name display position are changed accordingly.

Operation According to the above configuration, as the rice cooking operation progresses, the rice cooking process name and the process name display position change on the display means made of a liquid crystal display element. LCD display is LED
Unlike the display using light emission, the display contents can be easily seen even in bright places. In addition, since the process name display position changes, even if the rice cooking process name cannot be confirmed from a distant position, it is possible to confirm which rice cooking process it is based on the display position.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. FIG. 1 is a block diagram of a rice cooker showing an embodiment of the present invention, in which reference numeral 11 indicates a rice cooking means for cooking rice, 12 a control means for controlling the rice cooking means 11, and 13 a control means for controlling the rice cooking means 11. A liquid crystal display element (hereinafter referred to as
Display means 14 consisting of an LCD (referred to as LCD) is a liquid crystal driving means for displaying only the rice cooking process in progress on the display means 13 from among the plurality of rice cooking processes performed by the rice cooking means 11.

FIG. 2 is a circuit diagram of the rice cooker, and 15 is a commercial power supply. The rice cooking means 11 is composed of a rice cooking heater 11a, a relay contact 11b, and a relay coil 11c, and the relay coil 11c is energized and controlled by the control means 12, and the relay contact 11b is controlled to open and close. As a result, current flows from the commercial power supply 15 to the rice cooking heater 11a, so that the rice cooking heater 11a is controlled to be energized and a rice cooking operation is performed. On the other hand, process information during the rice cooking operation is outputted from the control means 12 to the liquid crystal driving means 14, and the liquid crystal driving means 14 drives the display means 13 using the information as input.
The display means 13 is arranged in the order of the rice cooking operation so that the process names of "pre-cooking", "cooking" and "additional cooking" can be displayed, and the liquid crystal driving means 14 can display the above-mentioned process names or erase the display. do. For example, if the pre-cooking is in progress, the display means 1 is displayed by the liquid crystal drive means 14.
Only the process name 13a of "Pre-cooking" located on the left side of 3 is displayed. If cooking is in progress, display means 1
3, the display of the process name 13a of "pre-cooking" is erased, only the process name 13b of "cooking" located in the center is displayed, and if additional cooking is in progress, the display of the process name 13b of "cooking" is hidden. Then, the process name 13c of "additional cooking" located on the right side of the display means 13 is displayed.

Since each step during the rice cooking operation is displayed on the liquid crystal display in this way, the name of the step can be confirmed even in a bright place, and the name of the step displayed on the display means 13 can be checked even from a distant position where the name of the step displayed on the display means 13 cannot be confirmed. If it is displayed on the left side, it is "pre-cooked", and if it is displayed in the center of the display means 13, it is "cooked", display means 13
If it is displayed on the right side of , you can confirm that it is "additional cooking".
Effects of the Invention As described above, according to the present invention, since the process name is displayed by the display means consisting of a liquid crystal display element, the process name can be confirmed even in a bright place. do it easily,
Furthermore, the displayed process can be confirmed even when the rice cooker is placed in a bright place and viewed from a distance.
