An additional display is provided to advise the user (FIG. 11).

As for the dishes that can be checked for completion in each automatic cooking, advice is additionally displayed at an appropriate timing at the next execution in the same manner as described above. As a result, the same failure is not repeated, and the finish is improved from the next time. If the failed item is not selected in the completion check, the additional advice is not displayed next time.

In the present invention, when the operation shown in screen number -12 in FIG. 7 during the setting of the cream puff is started, the start key 20 can be operated without operating the selection key to execute the operation of screen number -13. Operation becomes possible.

The same applies to screen numbers -35 and 36 in FIG. However, the display for instructing the operation of the start key 20 on the screen numbers -12 and 35 and the blinking of the "start key" for prompting the key operation are not performed. The surface of the start key is made of a translucent resin, and the LED is arranged behind the start key to turn on or blink.

In the “junior kitchen” genre, display data on dishes that the child likes and is interested in is stored in the external storage memory 7 or the internal storage memory 1 d of the microcomputer 1. In addition, the level of explanation is simplified compared to other genres, and kanji that can be read by elementary school students who are interested in cooking are used.

By the way, as described above, various variations can be set according to the concept of having a mode for a specific age group or a specific purpose, so that there is a future development.

(4) Initial Settings When a microwave oven according to one embodiment of the present invention is purchased and the power is turned on, display data relating to the initial settings stored in the external storage memory 7 is read out by the operation of the microcomputer 1, and The image is displayed on the liquid crystal display 9 via the display control circuit 8. FIG. 15 shows the display contents of this initial setting. The screen number -1 is displayed at the same time when the power is turned on, and the display is switched to the screen number -2 a few seconds later.

In the display of the screen number-2, the instruction "Press the chef key when using for the first time" is instructed. When the user presses the chef key 16 in accordance with the instruction, the screen shifts to the screen number-4. In this case, the display content is
Adjustment of the weight sensor required due to shocks during transportation of the microwave oven, baking to eliminate the smell of the oven, adjustment of the sound volume and display contrast, setting of the time, etc. should be performed before cooking Item. This need not necessarily be performed, but is effective for comfortable use of the microwave oven. These initial settings can be easily performed in an interactive manner with the display screen.

(5) Clarification of Start of Heating In the present invention, when a dish such as the cream puff described in the above item (3) needs to be heated many times and modified during the execution, In addition, it is configured such that the user is informed in advance in advance, and a screen prompting the operation of the start key 20 is displayed as needed in a series of operations.

For example, in the above cream puff making,
On screen numbers -36 and 42 in FIG. 8, illustrations for clarifying the number of heating stages are displayed. FIG. 16 shows the contents, and is represented by an illustration of a bus stop. Among them, FIG. 7A shows a display pattern at the screen number -36, in which the first bus stop blinks.
This shows a state in which heating of water and butter is about to be started. FIG. 7B shows a display pattern at the screen number -42, in which the second bus stop is blinking and heating of the fabric is to be started.

In the “everyday” cooking mode, which has not been described above, in addition to commonly used items such as “drink” and “thaw”, “food memo” is used to indicate the relationship with cooking by a microwave oven. Regardless of the presence or absence, cooking information that is convenient to know can also be displayed. For example, FIG. 26 shows the contents displayed when “food memo” is selected from the “daily” cooking mode and “tempura basic” is called from “fried knacks” in the cooking memo.

<Notification sound generator> Next, the notification sound generator in the present invention will be described. FIG. 17 is an electric circuit showing the notification sound generator. The notification sound generator 5 outputs a melody sound for imagining various scenes displayed on the liquid crystal display 9.

In FIG. 1, the microcomputer 1 has a notification sound output terminal 1b and an envelope control terminal 1c. When a signal is output from the notification sound output terminal 1b, the transistor Q1 is turned on to turn on the piezoelectric buzzer. 5a becomes operable, but the capacitor C1 is sufficiently charged,
If the high-level terminal voltage V1 is not generated between the ground terminal and the opposite terminal, the piezoelectric buzzer 5a does not operate.

As described above, when a signal is output from the envelope control terminal 1c while a signal is being output from the notification sound output terminal 1b, the transistor Q3 is also turned on with the turning on of the transistor Q2. When the current I flows, the capacitor C1 is sufficiently charged, the terminal voltage V1 becomes high level, and the piezoelectric buzzer 5a operates to output a notification sound.

FIGS. 18 (a) and 18 (b) show output waveforms of the notification sound output terminal 1b, the envelope control terminal 1c and the piezoelectric buzzer 5a when an operation sound (so) is output, and FIG. 19 (a). , (B) show the respective output waveforms in the case of outputting the adjustment sounds (sounds, dots). While the signal is being output from the envelope control terminal 1c, the piezoelectric buzzer 5a operates completely. , Envelope control terminal 1c
When the further output is cut off, the operation gradually attenuates at this point.

As can be seen from these figures, in the present invention, the frequency is made different depending on the musical note. In this example,
The sound of (so) is at 783 Hz, and the sound of (do) is at 104
It is set to 6 Hz.

FIG. 20 shows each melody for the operation sound, the start sound, the cancel sound, the knuckle and the heating end sound, and the waveform, frequency and time of each note. In microcomputer 1,
Basically, the main routine is cycled once in one cycle of the power supply frequency. In short, sound frequency data can be set once in one cycle of the power supply frequency. At this time, as shown in FIG. 20, when outputting the melody, the time interval for switching the frequency is 100 ms or more, which is sufficiently longer than the power supply frequency (60 Hz: 16.7 ms, 50 Hz: 20 ms) and can be switched. is there.

The notification sound of a conventional microwave oven is high, and is considered to be unpleasant especially for elderly people. For this reason, a melody uses a sound in the vicinity of 500 Hz to 1 KHz. Furthermore, in order to improve the height of the instep by sounding the piezoelectric buzzer with a square wave output from the microcomputer, an envelope control signal is output from other terminals of the microcomputer, and the frequency is switched by charging and discharging the capacitor by this signal. Rounds the square wave at the end of time or melody, creating a sound effect. These details are as described above.

<Microwave Oven Inspection System> Next, the microwave oven inspection system will be described. For systems that control extremely complex displays and sounds, such as the microwave ovens described above, the key point is to analyze the display contents and sound contents quickly and accurately in order to increase the inspection accuracy. .

In the present system, in order to meet this demand, the operation of the microcomputer 1 of the above-mentioned microwave oven normally causes the minimum inspection data such as display contents, melody patterns, control contents and the like required by the inspection machine to be converted. In order to minimize the number of output terminals of the microcomputer 1 required for the inspection data, an inspection apparatus for executing serial transfer of data is provided.

In this system, as described above, the display data is stored in the external storage memory 7 together with the screen number. Therefore, the screen is completed by overwriting various data such as cooking time data on the basic screen. That is,
If the screen number and the overwrite data are known, the display screen can be reproduced by providing the inspection machine with the same display data as the microwave oven. The inspection machine determines whether the display information obtained from the microwave oven matches each operation. FIG. 21 shows a conceptual diagram thereof.

However, before performing this inspection, it is necessary to confirm that the data of the display and the notification sound of the microwave oven and the data of the inspection machine match, and to confirm the display contents of each display screen. It is necessary to make sure that

FIG. 22 is a block circuit diagram showing a state in which the microwave oven is incorporated in the present inspection system. As is apparent from this figure, the data input / output signal line 29
A connection is made between the inspection machine 28 and the control circuit. More specifically, between the key circuit 3 and the signal input / output line of the microcomputer 1 and the inspection device 28, between the microcomputer 1 and the inspection device 28, between the sensor 4 and the signal input / output line of the microcomputer 1 and the inspection device 28, and external storage memory. 7 and the signal input / output line of the microcomputer 1 and the inspection device 28, and between the relay circuit 6 and the signal input / output line of the microcomputer 1 and the inspection device 28, and various data are supplied to the inspection device 28. Has become.

FIG. 23 is a diagram showing a flow of automatically inspecting the automatic cooking operation with the microwave oven according to the present invention by the present inspection system. As shown in the figure,
When the power is turned on, the microwave oven initializes the system and enters a standby state (steps D1, D2, D
3).

On the other hand, after turning on the power (Step P1) and initializing the system (Step P2), the inspection machine 28 proceeds to Step P3 of the heating setting operation, and performs the inspection of the microwave oven in order to inspect the automatic cooking. The key operation is simulated by electrically shorting the key switch, and the dish to be executed is determined.

By this operation, the microwave oven enters the state of the heating setting operation (steps D4 and D5), and the key input sound is emitted at the same time when the display content of the liquid crystal display 9 changes to the heating setting screen. The microwave oven always outputs data and the like regarding the display and the notification sound from the output terminal of the microcomputer 1.
At this time, the inspection device 28 reads the output level of the serial data, the relay, and the like, and determines whether or not the output level matches the specification (steps P4 and P5). If the specification does not match the specification, the inspection items performed on the microwave oven and the details of the troubles that have occurred are automatically stored in a storage element (a floppy disk or the like) in the inspection machine 28 (step P6).
