Description

TECHNICAL FIELD The present invention relates to a jar rice cooker used for general household use.

2. Description of the Related Art Conventionally, this type of jar rice cooker is composed of a heater and a heater control element, and has a rice cooking means for performing rice cooking and heat retaining operations, a menu setting means for setting two or more types of rice cooking menus, and this menu setting means. Storage means for outputting the rice cooking program of each menu stored according to the output of, and the control means for controlling the rice cooking means according to the rice cooking program output by the storage means to perform rice cooking and heat retention, The memory means outputs a rice-cooking pattern suitable for the rice-cooking menu set by the user with the menu setting means, and the control means controls the rice-cooking means in accordance with the rice-cooking pattern to adjust the heating and cooking of rice.

Problems to be Solved by the Invention With such a conventional configuration, the rice can be cooked with the heat power of the rice cooking pattern suitable for the rice cooking menu set by the user,
After that, when entering the heat retention operation, the rice cooking menu other than white rice,
For example, cooked rice and porridge were kept at the same temperature as white rice. Therefore, depending on the set rice cooking menu, the heat retention temperature is high, and if you keep it warm for a long time, the rice and ingredients at the bottom of the pot will be burnt and hard, or the heat retention temperature will be low and the rice will become pasty. There was a problem that I could not eat.

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

Means for Solving Problems In order to solve the above problems, the present invention comprises a heater and a heater control element, a rice cooking means for performing rice cooking and heat retaining operations, and a menu for setting two or more types of rice cooking menus. Setting means, second storage means for outputting the heat retention time of each cooked rice menu stored according to the output of the menu setting means, and measuring the heat retention time output by the second storage means from the start of the heat retention operation. A timer for outputting and a display means for displaying when the timer outputs are provided, a rice cooking pattern and a heat retaining time are set according to the rice cooking menu set by the menu setting means, and when the heat retaining time elapses, the display means displays. It is intended to be displayed.

Operation According to the above configuration, when the user sets the rice cooking menu by the menu setting means, the rice cooking pattern and the heat retention time suitable for the rice cooking menu can be set, and the water is heated according to the rice cooking pattern suitable for the menu. When the rice is cooked and the warming operation is started after the rice is cooked, the timer starts measuring, and when the warming time output by the second storage means is reached in accordance with the rice cooking menu set by the menu setting means, the timer outputs. Then, the display means can display to the user that the time period during which the user can keep warm is over and inform the user that the user must eat early.

Embodiment One embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a block diagram of a jar rice cooker according to an embodiment of the present invention. Reference numeral 1 denotes a heater for heating a pot and a heater control element for controlling energization of the heater. The rice cooking means for performing 2, the menu setting means by which the user sets two or more types of rice cooking menus, and the 3 outputs the rice cooking program of each menu stored in advance according to the output of the menu setting means 2. 1 storage means, 4 is a control means for controlling the rice cooking means 1 according to the rice cooking program output from the first storage means 3 to perform rice cooking and heat retention, 5 is a rice cooking menu set by the menu setting means 2. Second storage means 6 outputs a warming time of each menu stored in advance, and 6 is a timer, and the timer 6 measures when the control means 4 starts the warming operation. When started, and measures the incubation time of outputting of the second storage unit 5, and outputs. Reference numeral 7 is a display means including an LED or the like, which displays when the timer 6 outputs.

FIG. 2 is a circuit diagram of a jar rice cooker according to an embodiment of the present invention. Reference numeral 1 is a rice cooker, which is composed of a heater 7 for heating a pot and a relay 8 for controlling energization of the heater 7. ing. Reference numeral 2 denotes a menu setting means for the user to set a rice cooking menu. The menu setting means 2 is composed of a rotary switch and can set three kinds of rice cooking menus of white rice, cooked rice and porridge. Reference numeral 9 denotes a so-called one-chip microcomputer including a CPU, ROM, RAM, etc. The one-chip microcomputer 9 drives the transistor 10 and the relay 8 to control the energization of the heater 7, and also drives the transistor 11 to display means. The LEDs that make up 6 are turned on.

The operation of the jar rice cooker in the above embodiment will be described based on the flowchart of FIG.

When the user sets any one of white rice, cooked rice and porridge with the menu setting means 2, the one-chip microcomputer 9 relays according to a rice cooking program stored in advance by the rotary switch constituting the menu setting means 2. Drive 8 to adjust the heat and cook rice. Then, when the rice cooking is completed, the heat retaining operation is started, and in step 11, 12, 13 and 14, the heat retaining time suitable for the rice cooking menu set by the menu setting means 2 is selected. Then, the measurement is started in step 15, and when the heat retention time selected in step 16 is reached, the transistor 11 is driven in step 17 to turn on the LED constituting the display means 6.

In this way, when the user sets porridge in the rice cooking menu, it becomes paste-like, so if you set the cooked rice in a shorter heat retention time than white rice, the soup stock and ingredients will burn. Therefore, the display means 6 is activated in a shorter heat retention time to warn the user to eat earlier.

Effect of the Invention As described above, the jar rice cooker of the present invention sets the rice cooking pattern and the holding time according to the rice cooking menu set by the menu setting means, and the display means displays after the heat retention time has elapsed. By setting the rice cooking menu using the rice cooking menu setting means, you can set the rice cooking pattern and heat retention time that are suitable for the rice cooking menu, and the rice is cooked according to the heat of the rice pattern that is suitable for the rice cooking menu, and the rice is kept warm after cooking. , When the heat retention time determined by each rice cooking menu has elapsed, the display means displays and warns the user, so that the user can safely heat any rice in any rice cooking menu without waste. It's very convenient and very useful.
