BACKGROUND TECHNOLOGY In this type of conventional jar rice cooker, the rice cooking means cooks rice according to the rice cooking pattern, and the pre-cooking,
A rice cooking display means consisting of a liquid crystal display that displays the status of rice cooking operations such as finished cooking and additional cooking, a heat retention display means consisting of an LED that indicates that the rice is in a warming operation, and a rice cooking display that tells the user when rice cooking is finished. If the user is nearby when the rice cooking is finished, the user will hear the sound of the electronic buzzer to notify the user that the rice has finished cooking. It was determined that the rice was ready because the heat-retaining display means was lit to indicate that the rice was ready.

Problems to be Solved by the Invention In such a conventional configuration, when the rice is kept warm, the keep-warm display means lights up to inform the user that the rice is kept warm. Even if the rice becomes perishable more than 10 hours after it is cooked, it will not change, so if the user misunderstands or someone other than the person who cooked the rice uses it, it may become spoiled. There was a problem that I ended up eating a lot of rice.

An object of the present invention is to provide a jar rice cooker that solves these problems.

Means for Solving the Problems In order to solve the above problems, the jar rice cooker of the present invention includes a rice cooking means for performing a rice cooking operation, a rice cooking display means for displaying the rice cooking operation status on a liquid crystal display, and a rice cooking display means for displaying the warming operation status. This device is composed of a heat-retaining display means for notifying the end of rice cooking, a notifying means for notifying the end of rice cooking, and a completion display means for displaying the fact that the rice is finished in a text pattern on a liquid crystal and for a certain period of time from the end of cooking.

Effect With the above configuration, when the rice cooking means finishes cooking rice, the notification means notifies the user, and the rice completion notification means and the keep-warm display means display the information to inform the user that the rice is done and is being kept warm. Then, when a certain period of time has passed and the rice becomes perishable, the display on the rice completion notification means disappears to notify the user that the rice is perishable.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings. FIG. 1 shows a block diagram of a jar rice cooker according to an embodiment of the present invention, in which 1 is a rice cooking means consisting of a heater and a control section, and 2 is a rice cooking display that displays the rice cooking status of the rice cooking means 1 on a liquid crystal display or the like. It is a means. 3 is a notification means consisting of a buzzer, which, when rice cooking is finished, sounds to notify the user that the rice cooking has been completed. 4 is a heat retention display means consisting of an LED or the like, and when the rice cooking means 1 enters the heat retention operation,
It lights up to indicate that it has entered the warming operation. Reference numeral 5 denotes a cooking completion indicator, which is made of a liquid crystal display and displays complimentary sentences such as "The food is delicious" for a certain period of time.

Fig. 2 is a circuit diagram of a jar rice cooker showing an embodiment of the present invention, and Fig. 3 shows the operation section of the jar rice cooker, where 6 is a heater for cooking rice; A switch 9 consisting of a transistor 7 and a relay 8 opens and closes a connection between the power source and a commercial power source 10, thereby adjusting the thermal power. 11
is a so-called one-chip microcomputer consisting of ROM, RAM, CPU, etc., and it cooks rice by driving the switch 9 according to rice cooking patterns such as pre-cooking, finishing cooking, and additional cooking that are stored in ROM in advance. Adjust the heat power of the heater 6.
At the same time, the rice cooking display means 2 made of liquid crystal displays the process name of the rice cooking pattern such as pre-cooking. When the rice cooking is finished, the notification means 3 consisting of an electronic buzzer 12 will sound, and the completion display means 5 consisting of a liquid crystal display will display "The rice is cooked deliciously".
