Description

Description: TECHNICAL FIELD The present invention relates to a heating cooker capable of automatically cooking various cooking menus.

2. Description of the Related Art FIG. 6 shows a conventional operation part of a heating cooker. The menus that are frequently used are direct select keys 1 to 4. That is, when the cake key 1 is pressed, the indication "cake" is displayed on the display tube 5, and by pressing the start key 6, cooking can be started. That is, since cooking can be started by two operations, the operation is simple, easy and easy to use. Gratin key 2, warm key 3, raw defrost key 4
Is also the same. For the group of favorite menus that are used less frequently than the above-mentioned menus that are used frequently, first press the favorite menu key 7 and then the display tube 5
The "Preferences" indicator lights up. Next, the timer knob 8
When is turned, numbers 1 to 20 are displayed on the display tube 5, the numbers corresponding to the menus written in the menu table 9 are set, and the start key 6 is pressed to start cooking.
This favorite menu is complicated and difficult to use with 3 operations until the start of cooking.

SUMMARY OF THE INVENTION Problems to be Solved by the Invention That is, in the conventional setting of the favorite menu, the operation procedure is difficult to understand, and it is difficult to understand what to do after pressing the favorite menu 7. On the other hand, making all the favorite menus direct keys gives the impression that the operating unit is rather complicated, and there was a space limitation on the operating unit, which made it impossible.

The present invention solves such a conventional problem, and an object thereof is to make setting of a favorite menu easy to understand.

Means for Solving the Problems To achieve the above object, the heating cooker of the present invention illuminates a menu table from the rear with an EL display panel for the purpose of instructing the next operation when a favorite menu key is pressed. It is configured.

Function The illumination by the EL display panel makes it easy to perform complicated operations in the past by displaying the operation procedure one by one.

Embodiment One embodiment of the present invention will be described below with reference to the drawings.

FIG. 4 is a perspective view of the main body of the present heating cooker, in which the door 22 is opened and food is put into the heating chamber. In addition, FIG. 1 is an enlarged view of the operation unit 21. In FIG. 1, the menus that are frequently used as in the past are direct select keys 1 to 4, which are very easy to operate and easy to use. . For a favorite menu that is used relatively infrequently, first, when the favorite menu key 7 is pressed, the display of "favorite" is displayed on the display tube 5, and the favorite menu table 9 is backlit by the EL display panel. . FIG. 2 is an enlarged view of the menu table 9, but the letters or numbers in the menu table are made of a transparent material that transmits the light from the rear part, and the other parts do not transmit the light from the rear part. (For example, blacken). FIG. 3 shows the cross-sectional structure of the menu table. The menu table 9 is supported by the resin base 10, and the back plate 12 also screwed to the resin base 10 is arranged at the rear of the menu table 9. , Double-sided tape 15 on the back plate 12
Then, the EL display panel 11 is attached. Also EL display board 11
Are electrically connected to the printed circuit board 14 by lead wires 14. The control circuit of the cooking heater is wired on this printed circuit board. From the above, before the favorite menu key 7 is pressed, the EL display panel 11 is off, so no characters are displayed in the menu table 9, but by pressing the favorite menu key 7, the EL display is displayed. The panel 11 lights up, and the letters on the menu table 9 appear to shine by the EL light and indicate the selection of the menu number. In other words, when the menu table is needed, it only looks like it glows.
You can see the operation procedure at a glance. Next, from the menu table, the number corresponding to the menu to be cooked is set using the timer knob 8 shown in FIG. The number is displayed through the display tube 5.

On the other hand, the EL display panel itself has a very clean and dignified light emission and emits a uniform light emission over the entire surface, so that the center of the favorite menu table is bright and the surroundings are dark, such as partial emission lamps and LEDs. Since there is no unevenness, and since it is very flexible and thin, it can be configured by a simple work of simply sticking it to the narrow portion between the menu table 9 and the back plate 12 in FIG.

FIG. 5 is a block diagram of the control circuit of the cooking heater. The controller 16 forming the center of the control circuit is a cake key 1, a favorite menu key 7, a start key 6
It is determined whether or not is input, and if it is input, the content is displayed through the display tube 5. When the favorite menu key 7 is pressed, the EL display drive circuit 1
By sending an ON signal to 7, the EL display panel 11 is turned on. Also, in order to display the number of the favorite menu, input the information from the timer knob 8. Also, while inputting the humidity sensor 19 and the temperature sensor 20, through the heating means 18,
Control food heating.

Effects of the Invention As described above, according to the heating cooker of the present invention, the following effects can be obtained.

(1) It became very easy and easy to understand by displaying the list of favorite menus only when necessary, which was difficult to understand in the past.

(2) Since the EL display panel itself emits light uniformly over its entire surface, when the favorite menu table is backlit, unevenness such as bright center and dark surroundings, such as partial emission, does not occur.

(3) Since the EL display panel itself is extremely flexible, it will not be damaged during assembly and workability will be good.

(4) Since the thickness of the EL display panel itself is very thin, about 1 mm, there are not many restrictions on space, and the operating part of the heating cooker can be designed to be thin and smart.
