Regardless of the presence or absence, you can display useful cooking information if you know it. For example, FIG. 26 shows the content displayed when "cooking memo" is selected from the "daily" cooking mode and "basket of tempura" is called from the "fried food tips".

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

In the figure, the microcomputer 1 is provided with 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 and the piezoelectric buzzer is turned on. 5a becomes operable, but the capacitor C1 is fully charged,
The piezoelectric buzzer 5a does not operate unless the high-level terminal voltage V1 is generated between the ground terminal and the opposite terminal.

As described above, when the signal is output from the envelope control terminal 1c while the signal is output from the notification sound output terminal 1b, the transistor Q3 is also turned on as the transistor Q2 is turned on. 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 alarm sound output terminal 1b, the envelope control terminal 1c and the piezoelectric buzzer 5a when outputting the operation sound (so), and FIG. 19 (a). , (B) show respective output waveforms in the case of outputting the adjustment sound (so, do), and the piezoelectric buzzer 5a operates perfectly while the signal is being output from the envelope control terminal 1c, respectively. , Envelope control terminal 1c
When the output of is stopped, the operation gradually attenuates at this point.

As can be seen from these figures, in the present invention, the frequency is made different for each note. In this example,
The sound of (So) is 783Hz, and the sound of (Do) is 104
It is set to 6 Hz.

FIG. 20 shows the melody for the operation sound, the start sound, the cancel sound, the click sound and the heating end sound, and the waveform, frequency and time of each note. In the microcomputer 1,
Basically, one cycle of the main routine is cycled once per cycle of the power supply frequency. In short, the 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 the conventional microwave oven is high, and it is said to be an unpleasant sound especially for the elderly. Therefore, as for the melody, the sound in the vicinity of 500 Hz to 1 KHz is used. Furthermore, in order to improve the instep height by ringing the piezoelectric buzzer with the square wave output from the microcomputer, the envelope control signal is output from the other terminal of the microcomputer, and the frequency is switched by charging and discharging the capacitor by this signal. It creates a sound effect by rounding the square wave at the end of time and melody. These details are as described above.

<Microwave Oven Inspection System> Next, the microwave oven inspection system will be described. In order to improve the inspection accuracy for extremely complicated display and sound control systems such as the microwave oven, the key point is to analyze the display contents and sound contents accurately at high speed. .

In this system, in order to meet this demand, the minimum inspection data required by the inspection machine, such as display content, melody pattern, control content, etc., is normally set by the operation of the microcomputer 1 of the microwave oven. In order to minimize the output terminal of the microcomputer 1 required for the inspection data while the program is proceeding, the inspection device for serially transferring the data is provided.

In the present system, as described above, the display data is stored in the external storage memory 7 together with the screen number. Therefore, various data such as cooking time data is overwritten on the basic screen to complete the screen. That is,
If the screen number and overwrite data are known, the display screen can be reproduced by allowing the inspection machine to have the same display data as the microwave oven. The inspection machine determines whether or not the display information obtained from the microwave oven matches each operation. The conceptual diagram is shown in FIG.

However, before carrying out this inspection, it is confirmed that the data relating to the display and the notification sound of the microwave oven and those data possessed by the inspection machine match, and the display contents of each display screen. It is necessary to make sure.

FIG. 22 is a block circuit diagram showing a state in which the above microwave oven is incorporated in the present inspection system. As is clear from this figure, the data input / output signal line 29 is
A wire is connected between the inspection machine 28 and the control circuit. Specifically, between the key circuit 3 and the signal input / output line of the microcomputer 1 and the inspection machine 28, between the microcomputer 1 and the inspection machine 28, between the sensor 4 and the signal input / output line of the microcomputer 1 and the inspection machine 28, an external storage memory 7, the signal input / output line of the microcomputer 1 and the inspection machine 28, and the relay circuit 6 and the signal input / output line of the microcomputer 1 and the inspection machine 28 are respectively connected, and various data are supplied to the inspection machine 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 the standby state (steps D1, D2, D
3).

On the other hand, after the power is turned on (step P1) and the system is initialized (step P2), the inspection machine 28 shifts to step P3 of heating setting operation, and in order to inspect the automatic cooking, By electrically short-circuiting the key switch, the key operation is simulated and the dish to be executed is determined.

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

After storing the contents of the trouble or the like, or if the operation in the heating setting state (including display and notification sound) matches the specifications, the next inspection is performed. As a next inspection, in order to start heating, the key switch of the microwave oven is electrically short-circuited, and a pseudo start key operation is performed to start heating (step P7).

By this operation, the microwave oven is brought into the heating state (steps D6 and D7), and at the same time the display contents are changed to the heating state screen, the key input sound is outputted. At this time, the inspection machine 28 reads the serial data from the microwave oven, the output level of the relay, etc., and determines whether or not the specifications match the specifications (steps P8 and P9). If the result of this determination is that the specifications do not match, the inspection items applied to the microwave oven and the details of the problems that have occurred are automatically stored in a storage element (floppy disk or the like) in the inspection machine 28 (step P10).

After storing the contents of the trouble or the like, or if the operation of the heating state (including the display and the notification sound) matches the specifications, the next inspection is carried out. As the next inspection, the voltage and resistance of the microwave oven sensor that determines the end of automatic cooking are electrically changed by the inspection machine 28 (step P11).
By this operation, the microwave oven finishes heating (step D8) and returns to the standby state (step D3), and at the same time the display content on the liquid crystal display 9 changes to the standby state screen, a termination sound is emitted.

On the other hand, the inspection machine 28 reads the serial data from the microwave oven, the output level of the relay, etc., and determines whether or not the specifications are met (steps P12, P).
13). If the determination does not match the specifications, the inspection items applied to the microwave oven and the details of the problems that have occurred are automatically stored in a storage element (floppy disk or the like) in the inspection machine 28 (step P14). If the contents of the problem are stored, or if the serial data, relay output, etc. match the specifications, the inspection is terminated. Such an inspection is performed for all dishes and all operations of the microwave oven. Then, the stored contents of the trouble and the like are confirmed by analyzing after the completion of all inspections, and countermeasures are taken against them.

<TV display system> If the contents and sound displayed on the display of a cooking device such as a microwave oven can be reproduced by an external monitor TV or the like, a demonstration at an exhibition or a briefing session, or a sale It is very convenient because it can be used for explanations and advertisements in stores.
In order to meet this request, this system is configured to serially transfer the microcomputer internal data, as in the above inspection system. A specific example is shown below.

FIG. 24 is a block circuit diagram showing a state in which the microwave oven is incorporated in the present television display system. In the figure, a television display microcomputer 1'is connected to a monitor television 30 through a display control circuit 8 '.
