Description

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

BACKGROUND ART A conventional jar rice cooker of this type includes a heater and a heater control element, including a rice cooking means for cooking rice and keeping warm, a menu setting means for setting two or more types of rice cooking menus, and a menu setting means for setting two or more types of rice cooking menus. The rice cooking means is comprised of a storage means for outputting a rice cooking program for each menu stored in accordance with the output of the storage means, and a control means for controlling the rice cooking means to cook and keep the rice warm in accordance with the rice cooking program output from the storage means. The rice is cooked with a heating power of a rice cooking pattern suitable for the rice cooking menu selected by the user.

Problems to be Solved by the Invention In such a conventional configuration, rice is cooked with a heating power of a rice cooking pattern suitable for the rice cooking menu selected by the user. For example, cooked rice and porridge were kept at the same temperature as white rice. Therefore, depending on the rice cooking menu, if the heating temperature is high and the rice is kept warm for a long time, the rice and ingredients at the bottom of the pot may burn and become hard, or the heating temperature may be low and the food will not taste good when eaten. There were several problems.

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

Means for Solving the Problems In order to solve the above problems, the present invention provides a rice cooking means that includes a heater and a heater control element, and that performs rice cooking and heat keeping operations, and a menu that sets two or more types of rice cooking menus. a setting means; a first storage means for outputting a rice cooking program for each menu stored according to the output of the menu setting means;
a second storage means for outputting the temperature keeping temperature of each menu stored in accordance with the output of the menu setting means; a rice cooking program outputted by the first storage means and a keeping temperature outputted by the second storage means; Therefore, it is constructed by a control means for controlling the rice cooking means to cook rice and keep it warm.

Effect: According to the above configuration, the first storage means outputs the rice cooking program according to the rice cooking menu set by the user using the menu setting means, so that the control means controls the rice cooking means in accordance with the rice cooking program. Cook rice at the appropriate heat level for the rice cooking menu. When the rice cooking is completed and the warming operation starts, the second storage means outputs the warming temperature according to the rice cooking menu set in the menu setting means.
The control means can control the rice cooking means accordingly to keep the rice warm at a temperature suitable for the set rice cooking menu.

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, and 1 is composed of a heater that heats the pot and a heater control element that controls electricity supply to the heater, and controls rice cooking and warming operations. 2 is a menu setting means for the user to set two or more types of rice cooking menus; 3 is a rice cooking means for outputting a pre-stored rice cooking program for each menu according to the output of the menu setting means 2; 1 storage means, 4 a second storage means for outputting the warming temperature of each menu stored in advance according to the output of the menu setting means 2, 5 a rice cooking program output from the first storage means 3, and the above-mentioned rice cooking program. It is a control means that controls the rice cooking means 1 to cook rice and keep it warm according to the heat retention temperature output from the second storage means 4.

With the above configuration, the user can simply set the menu setting means 2 to cook rice with the heat level of the rice cooking program suitable for the rice cooking menu set by the menu setting means 2. It is kept warm at the same suitable temperature.

FIG. 2 shows a circuit diagram of a jar rice cooker according to an embodiment of the present invention. Reference numeral 1 denotes rice cooking means, which is composed of a heater 6 that heats the pot and a relay 7 that controls energization to the heater 6. ing. Reference numeral 2 denotes a menu setting means by which the user sets a rice cooking menu.This menu setting means 2 is composed of a rotary switch, and can set three types of rice cooking menus: white rice, cooked rice, and porridge. 8 is CPU, ROM,
This is a so-called one-chip microcomputer consisting of RAM, etc., and this one-chip microcomputer 8 is a transistor 9.
And the relay 7 is driven to control energization to the heater 6.

The operation of the Jiyar rice cooker in the above embodiment is explained in the third example.
This will be explained based on the flowchart shown in the figure.

When the user sets either white rice, boiled rice, or porridge using the menu setting means 2, the one-chip microcomputer 8 follows the rice cooking program set using the menu setting means 2 among the rice cooking programs stored in advance. , the relay 7 is driven to adjust the heat and cook the rice. When the rice cooking is completed, the warming operation starts, and then step 10.
At steps 11, 12, and 13, a heat retention temperature suitable for the rice cooking menu set by the menu setting means 2 is selected. According to the heat retention temperature, step 14,1
At steps 5 and 16, the relay 7 is driven to adjust the heating temperature of the heater 6 so that the temperature is maintained at a temperature suitable for the set rice cooking menu.

In this way, when the user sets porridge on the rice cooking menu, the user sets a higher temperature to keep it warm so that it is easier to eat, and when the user sets rice porridge, the temperature is set to a lower temperature to prevent the ingredients and soup from burning. I have to.

Effects of the Invention As described above, in the jar rice cooker of the present invention, rice is cooked using a cooking pattern suitable for the rice cooking menu set by the user, and after the rice is cooked, Since the rice is kept warm at the insulating temperature, no matter what rice cooking menu you choose, you can always eat it deliciously, making it extremely convenient and useful.
