Description

[Detailed description of the invention] Industrial applications The present invention is a jar rice cooker used in general households.

This relates to cooking appliances such as automatic bread makers and open cookers.

2. Description of the Related Art In conventional cooking devices of this type, various cooking menus are selected, the cooking menu is displayed only during cooking, and the display is turned off as soon as cooking is completed.

Problems to be Solved by the Invention However, in such conventional cookers, the cooking menu is displayed only while cooking, and after cooking is completed, the cooking menu disappears.
There was a problem in that when food was stored as it was by keeping it warm, it became difficult to tell what was on the cooking menu. There was also the problem that a cooking menu had to be set each time cooking was performed.

The present invention solves these problems and aims to provide a cooking device that can continue to display a selected cooking menu.

Means for Solving the Problems In order to solve the above problems, the cooking device of the present invention includes a heating means such as a heater for heating the food, a menu selection means for selecting the cooking menu 3, and a menu selection means for selecting the menu. Menu determining means for determining the menu selected by the means; Menu storage means for storing the menu determined by the menu determining means; Menu display means for displaying the stored menu in response to a signal from the menu storage means. and a control means for controlling the heating means to perform cooking according to the menu stored in the menu storage means.

According to the "double display function", it is possible to continue displaying the cooking menu selected once and displaying the same cooking menu until it is changed by the menu selection means, even after the cooking is completed. When preserving cooked food by keeping it warm, etc.
You can continue to display the cooking menu. With such a simple configuration, an easy-to-use and convenient cooking device can be provided.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. FIG. 1 shows a diagram of a rice cooker according to an embodiment of the present invention, in which 1 is a heating means such as a heater for heating food, 2 is a menu selection means for selecting a cooking menu, and 3 is a menu selection means for selecting a cooking menu. Menu determining means for determining the menu selected by the selecting means 2; menu storing means for storing the menu determined by the menu determining means 3 of the 4-bar; menus stored by signals from the menu storing means 4 of the 5-bar; 6 is a control means that controls the heating means to perform cooking according to the menu stored in the menu storage means.

FIG. 2 shows a circuit diagram of a rice cooker according to an embodiment of the present invention, which is made up of a microcomputer 7 and peripheral circuits. The microcomputer 7 shown here is C
It is a so-called one-chip microcomputer consisting of a PU, ROM, RAM, input/output capo-1, etc. 8 is a temperature sensing element, and this temperature sensing element 8 is connected to an input port of the microcomputer 7 via an A/D converter 9.

57\-7 As a result, W3. The temperature signal from the temperature element 8 is converted into a binary code and read into the microcomputer 7. 1
0 is a rice cooking switch, 11 is a menu switch for selecting a rice cooking menu, and 12 is a cancel switch, each of which is input to the microcomputer 7 to determine whether or not it has been pressed. Reference numeral 13 denotes a liquid crystal display element, and this liquid crystal display element 13 displays the rice cooking process (pre-cooking, finished cooking, uneven cooking, warming) and rice cooking menu (white rice, white rice, etc.) shown in FIG.
(Takikomi, Okowa, Brown rice) are displayed separately. Reference numeral 14 denotes an AC power supply. A series circuit of a heater 15 for heating food and a relay contact 16 is connected to the AC power supply 14, and a current is supplied to the relay coil 18 via a transistor 17 in response to a signal from the output port of the microcomputer 7. The relay contact 16 is configured to be opened and closed by flowing the current. 19 is a DC power supply for operating the circuit described above, which includes a transformer, diode bridge, capacitor, resistor,
It consists of a Zener diode.

6 b.

Next, the operation of the rice cooker configured as above will be explained. FIG. 4 shows a flowchart of a program stored in the ROM in the microcomputer T, and the operation of the program shown in this flowchart will be explained.

At step ■, select "White rice" from the menu.
, the program proceeds to step (2), where it is determined whether or not the menu switch 11 has been pressed.If the menu switch 11 has not been pressed, the menu set in step (2) is displayed on the liquid crystal display element 13. If the menu switch 11 is pressed in step ■, it is determined whether the menu is "white rice" in step ■, and if the menu is "white rice", the menu is set to "cooked rice" in step ■, and the menu is set to "cooked rice" in step ■. Proceed to. If the menu is not "white rice" in step ■, proceed to step ■, and determine whether the menu is "takikomi". If the menu is "takikomi", in step ■, the menu is changed to "takikomi".
Set it to "Okowa" and proceed to step ■. If the menu is not "Takikomi" in step ■, proceed to step ■.

In step ■, check whether the menu is "Okowa" or not.
-, and if the menu is "Okowa", set the menu to "Brown rice" in step ■, and proceed to step ■. If the menu is not "Okowa" in step ■, proceed to step 0, set the menu to "white rice", and proceed to step ■.

In step 0, it is determined whether or not the rice cooking switch 10 is pressed. If the rice cooking switch 10 is pressed, the process proceeds to step 0, and the rice cooking mode is entered according to the set menu. According to the temperature and time, the heater 15 is energized and rice is cooked, and step 0
Determine whether or not the rice cooking is complete. If the rice cooking is not completed, go back to step @. If the rice cooking is completed at step 0, go to step 0 and enter the keep warm mode to keep the cooked rice warm. , return to step ■.

If Cooking Rice Nuinoch 10 is not pressed in step ■,
Proceed to step [phase], determine whether or not the rice is in the keep warm mode, and if it is not in the keep warm mode, go to step [phase] to enter the standby mode, and perform all of the rice cooking processes (pre-cooking, cooking, uneven cooking, keeping warm). Clear the display and return to step ■.

If it is in the keep-warm mode at step [phase], the process advances to step O, and it is determined whether the cancel switch 12 is pressed. If the cancel switch 12 is pressed, the process advances to step [phase], and on the other hand, If the cancel switch 12 is not pressed, the process advances to step 0.

As described above, according to one embodiment of the present invention, the rice cooking menu once selected can be continued to be displayed, so that the same rice cooking menu can be displayed until it is changed by the menu switch 11. As a result,
After the rice is cooked, even if it is in keep warm mode or standby mode, the menu can continue to be displayed when the rice is stored, so you can easily see what is inside, making it easier to use. be.

Effects of the Invention As is clear from the description of the above embodiments, according to the present invention,
- It is possible to continue displaying the cooking menu once selected, so that the same cooking menu can be displayed until changed by the menu selection means, even after cooking is completed. When storing food as it is by keeping it warm, etc., the cooking menu can continue to be displayed, making it easy to see what's inside the cooker, making it easy to use and convenient. This makes it possible to provide a cooker with a high level of functionality.
