Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating cooker having a menu selection function and capable of selectively using a heating pattern corresponding to a plurality of types of menus for cooking.

[0002]

2. Description of the Related Art In recent years, in this type of heating cooker such as a rice cooker, an oven, and a microwave oven, it has become possible to selectively execute a plurality of types of menus by controlling the input of heating means with a microcomputer. Therefore, it is becoming possible to select and set a desired menu from a plurality of types of menus by operating a menu selection switch. For example, in the rice cooker, each time you press one menu selection switch, each course of multiple types of rice menu such as standard of white rice cooked, hard or soft eyes of white rice cooked, brown rice cooked, cooked, porridge cooked, etc. is selected cyclically. Configured to be set.

Further, in the case of cyclically selecting a plurality of types of menus each time one menu selection switch is operated in this way, it is necessary to operate the menu selection switch for each cooked rice, and this trouble is solved. For this purpose, the standard course of white rice cooking, which is a standard menu that is mainly used, is stored in advance in the manufacturing process, and when the off switch is operated to stop the rice cooking and heating process, the standard course of white rice cooking is changed. It has been proposed to configure the automatic setting so that when the rice is cooked in the standard course of white rice cooking, the start switch can be operated immediately without performing the menu selection operation. Every time the menu set by pressing the menu selection switch is updated, the updated menu is stored. Form, it has been proposed which is adapted currently executed menu when stopping the heating process by operating the changeover switch is automatically set.

[0004]

In the above prior art, in the case where the standard course of white rice cooking is automatically set when the off switch is operated, the stored menu is set to the standard course of white rice cooking. There is a problem that you have to operate the menu selection switch each time you mainly cook rice outside of this standard course,
In addition, if the menu executed this time is automatically set when the off switch is operated, the menu selection switch must be operated each time when rice is cooked on a different menu from the previous one, for example, the standard course of white rice cooking, which is the standard menu. There is a problem.

These problems are that the function of automatically setting a standard menu when the off switch is operated and the function of automatically setting a desired menu that is arbitrarily stored when the off switch is operated cannot be selectively used. Therefore, there is a problem that the necessity of operating the menu selection switch increases, and if this operation is forgotten, rice is cooked unintentionally.

Therefore, the present invention makes it possible to selectively use a mode in which a standard menu is automatically set when the heating process is stopped and a mode in which an arbitrarily stored desired menu is automatically set, thereby improving the usability. The purpose is to provide a cooker.

[0007]

The cooking device according to the present invention comprises:
Menu selecting means 30 for selecting one from a plurality of types of menus, and operating means 32 for setting a desired menu from the menus selected by the menu selecting means 30.
And a menu storage means 48 for storing the menu set by the operating means 32, a normal mode for setting and displaying a standard menu when the heating stroke is stopped, and a menu stored in the menu storage means 48 when the heating stroke is stopped. It is provided with a mode selection means 33 for selecting a memory mode to be set.

[0008]

In the heating cooker of the present invention, when the normal mode is selected by the mode selecting means 33 with the above-mentioned configuration, the standard menu is automatically set when the heating process is stopped, and the standard menu is not operated in the next cooking without operating the menu selecting means 30. You can start cooking the menu. On the other hand, when the memory mode is selected by the mode selection means 33, the desired menu stored in the menu storage means 48 is automatically set via the operation means 32 when the heating process is stopped, and the menu selection means 30 is operated in the next cooking. It is possible to start cooking of the desired stored menu without the need.

Next, the operation of the above structure will be described with reference to FIGS.

First, the mode setting operation will be described with reference to the flow chart of FIG. 3. When the mode 28 is set to the normal mode and the character 28 "normal" is lit near the upper portion of the character 23 "white rice A", the mode is set. When the presence or absence of the switch signal of the selection switch 33 is judged, and when the mode selection switch 33 is operated, the memory mode is set by the mode setting means 47 based on this signal and the character 28 "normal" is extinguished and the menu storage means. 48
The menu stored in is displayed by the lighting of the character "memory" 28A. After this, the mode selection switch 33
When the mode selection switch 33 is operated again, it is set to the normal mode by the mode setting means 47 based on this signal, and the "memory"
Character 28A turns off and the character "Normal"
28 lights up.

Next, the operation of storing and setting the menu in the memory mode will be described with reference to the flowchart of FIG.

Now, assuming that the white rice B course is stored in the menu storage means 48 and the character 28A "memory" is lit above the character 24 "white rice B", the control means 38 switches the off switch 31. The presence or absence of a signal is determined, and the stored white rice B course is automatically set when the off switch 31 is operated, and the white rice B course is surrounded by the enclosing frame 27. When the off switch 31 is not operated, the menu selection switch 30 Presence / absence is determined. Then, when the rice cooking switch 29 is pressed with the menu selection switch 30 not being operated, rice cooking is performed in the white rice B course. On the other hand, when the menu selection switch 30 is operated, the set menu is updated. Now, assuming that the brown rice course is set and the character 25 "Brown rice" is displayed by lighting the box 27, Next, it is determined whether or not there is a switch signal from the memory switch 32, and when the memory switch 32 is pressed, the menu information stored in the menu storage means 48 is updated to brown rice. The same judgment is made sequentially, and each time the menu selection switch 30 is pressed normally, a plurality of menus are cyclically selected and set, and separately from this, each time the memory switch 32 is pressed, the menu information of the menu storage means 48 is set. The menu stored in the menu storage means 48 is automatically set when the heating switch is stopped by pressing the off switch 31.

Next, the operation of the normal mode will be described with reference to the flow chart of FIG. 5. In this example, the presence or absence of the switch signal of the off switch 31 and the menu selection switch.
The presence or absence of 30 switch signals continues to be determined in sequence, and each course of white rice A, white rice B, brown rice and porridge is cyclically set based on the switch signal of the menu selection switch 30, and which menu is set. Even if it is turned on, the white rice A course which is a standard menu is automatically set based on the switch signal of the off switch 31. And Figure 2
Is a memory mode in which the character 28A of "memory" is lit, and when the rice cooking switch 29 is pressed, rice is started with the menu of the white rice A course surrounded by the frame 27, and the well-known hot water cooking process, rice cooking process, unevenness When the heating process is stopped by pressing the OFF switch 31, the white rice B course stored in the menu storage means 48 is automatically set and the character 24 "white rice B" is displayed in the box 27. Be surrounded. When the rice cook switch 29 is pressed in this state, rice is cooked in the white rice B course. On the other hand, when the mode selection switch 33 is pressed to set the normal mode, the white rice A course which is the standard menu is automatically set. As described above, in the above-described embodiment, the operation of the mode selection switch 33 causes the off switch.
When the heating process is stopped by 31, the normal mode is automatically set to the white rice A course which is a standard menu, and the desired menu stored in the menu storage means 48 when the heating process is stopped by the off switch 31. Since the memory mode automatically set to can be selectively executed, when the user mainly cooks rice in the white rice A course, the normal mode can be used to start cooking rice without operating the menu selection switch 30. Alternatively, in the case of mainly cooking rice with a menu other than the white rice A course, by storing the desired menu in the menu storage means 48 by the storage operation means 32, the menu selection switch 30 can be operated by using the memory mode. Instead, you can start cooking rice with a desired menu other than the white rice A course, improving usability. In addition, the operation test of all the switches is generally performed in the manufacturing process. However, even if the switch is shipped with the menu set arbitrarily, the user can use it from the white rice A course in the normal mode, which causes inconvenience. , Which also simplifies the manufacturing process. On the other hand, as in the conventional method, the menu selected every time the menu selection switch is operated is memorized each time, and it is necessary to ship with the white rice A course set, which makes manufacturing troublesome. . Further, a character 28 of "normal" is provided in the vicinity of the character 23 indicating the standard menu, and a character 28A of "memory" is provided in the vicinity of the characters 24 to 26 indicating other menus, respectively. The normal mode setting state is indicated by the lighting of the character 28, and the memory mode setting is indicated by the lighting of the character 28A of "memory" and the stored menu is displayed. However, there is no risk of problems such as boiled rice and softened rice when white rice is cooked with the amount of porridge.

The present invention is not limited to the above embodiment, but various modifications can be made within the scope of the gist of the present invention. For example, the rice cooker has been described as an example, but it can be applied to other heating cookers such as an oven and a microwave oven. Also, although the selection display of the menu is performed by lighting the surrounding frame, it may be performed by another display method such as lighting of characters,
Further, although the mode display means is performed by lighting the characters, it may be performed by lighting the symbols or the lamps.
