Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a heating device such as a microwave oven, an electric oven, a gas oven, or a combination thereof.

In conventional heating devices such as ovens and microwave ovens, heating data must be set prior to heating.

An operation procedure for setting such heating data using a conventional heating device will be explained. FIG. 8 is a perspective view of the main body showing an example of a conventional heating device, and FIG. 9 is a detailed view of the same operation panel. The operation panel 2 provided on the front of the main body 1 includes an output key 3 for selecting the output, an indicator light 4 for displaying this, ten numeric keys 6, and a 4-digit numeric display 6 for displaying the output. A start key 7 for instructing the start of heating, and a clear key 8 for canceling the set heating pattern are arranged. The key operation procedure when heating for 10 minutes at HIGH on such an operation panel is as follows.

Problems to be Solved by the Invention However, with this configuration, heating data cannot be set unless six keys are pressed. If you make a mistake in key operation even once during this time, you must erase it with the clear key 8 and start over from the beginning. Moreover, if the start key 7 is pressed without noticing the erroneous operation, cooking will naturally fail.

In order to simplify this troublesome operation, a card with a magnetic tape with a heating sequence written on it is prepared, and when the card is inserted, the heating sequence is read by a magnetic head, and the settings are automated. It has been commercialized. However, even in such a card type, the following drawbacks remain.

■ The amount of data written to the card is large, and there is a high possibility that reading errors will occur during communication with the head.

■ It is difficult to judge whether the heating sequence was reliably performed manually.

■ It's easy to lose your card. Also, it is difficult to search because it is broken up into pieces.

In view of this background, the present invention provides a heating device that allows heating data to be set easily and reliably, that notifies the operator of successful data input, and that is equipped with an input device that does not dissipate like a card. It is something that will be realized.

Means for Solving the Problems The heating device of the present invention has a barcode reader, and has cooking water bound in the form of a book, and each page on which each dish of the cooking water is described. It consists of a barcode with heating data corresponding to the dish printed or pasted on it, and the heating data is read before and after and sandwiched between check data and the name.

Function: The heating device of the present invention reads and checks the barcode on cooking water by scanning with a barcode reader.
) data and heating data, and by inspecting the read check data, the validity of the heating data can be determined.

Example The present invention will be described in detail below with reference to the drawings.

FIG. 1 is a perspective view of the main body showing an embodiment of the present invention. An operation panel 2 is provided on the front of the main body 1, and has three output keys 3, ten numeric keys 6, a start key 7, and a clear key 8 for manual setting, as in the conventional example shown in FIG. ．． Numeric display section 6 (not shown).

It is equipped with an output indicator light 4. Reference numeral 9 denotes a pen-shaped pickup equipped with a magnetic head or an optical head at its tip, and reads out predetermined data by scanning the bar code 10. In the barcode 10, heating data and read check data for each menu are recorded in binary numbers.

FIG. 2 shows an example of the barcode, in which heating data is read and check data is sandwiched between the barcodes. That is, by placing read check data unrelated to control data before and after the most important heating data, whether or not the head has correctly read the data is confirmed by matching the codes before and after this data.

If these reading check data do not match, it means that an error such as the head floating occurred during the reading process, and the heating data located in the middle is also suspicious. Prompts the user to perform a read operation.

Furthermore, if the read check data is made into dish name code data, when the heating data is successfully input, this dish name code is sent back to the user through notification means such as display or voice synthesis, and whether or not this is the predetermined code is sent back to the user. This allows the user to indirectly know whether or not the heating sequence data located in the middle has been correctly read. An 8-bit barcode can code 266 different menus, and even if all the menus listed on Cooking Water 11 were coded, the amount of data would increase by a very small amount. Note that the first code is a standby code in preparation for reading.

Now, this barcode data is processed as follows by the circuit shown in FIG. First, the barcode signal read by the head 12 is amplified by the amplifier 13 and input to the input port IN3 of the microcomputer 14. The standby code at the beginning puts the microcomputer 14 into data reading mode, and the barcode data that is input one after another is stored in the storage section (in the example, R) in the microcomputer 14.
AM). Then, when the final bit is read, the barcode data in the RAM is decoded.

First, the heating sequence name codes at the beginning and end of the data are compared. In this example, it is checked whether X"eB" match.

As mentioned above, if this does not match, an error has occurred due to the head 12 coming off the barcode 10 during the reading process, and of course the heating sequence data located in the middle is also suspicious. An error message is displayed and the user is prompted to perform a read operation using the pen-shaped pickup again.

On the other hand, if the heating sequence name codes match, it means that reading by the head was successful, and it can be said that reading reliability of heating sequence data located in the middle is high. Furthermore, although the example in FIG. 2 does not include a parity check, if a parity check function is added to this, the reliability of reading heating sequence data can be said to be perfect.

This heating sequence data is then written to a predetermined address in the RAM. That is, the output control and timer control unit sequences are preset.

Reference numeral 16 denotes an output control unit that changes the average value of power supplied to the heating source 16 (in this example, a magnetron) by changing the time ratio of intermittent on and off periods.

The on/off ratio is determined based on the data written to the output control register in the RAM. Reference numeral 17 denotes a timer control section which controls the heating time based on the data written in the register by controlling the timer in the RAM.

□′Now, set the read check data as the dish name code,
An example of notifying this will be described.

First, an example of notification using synthesized speech will be described with reference to FIG.

The microcomputer 14 outputs voice selection address signals vS15 to vS0 in accordance with the decoded code.

For example, the code name of “Roast Balk”
If expressed in 0-base, the audio signal with 10-base code "107" is X"3000" to X"3FFF" in memory 18.
If it is stored in the address, the start address X"3000" (
Binary code “001100ooooooooooo”
) is output. FIG. 6 is a timing chart showing the timing relationship of each signal, and the audio selection address signal is output at ■. Then, the CLA signal is output at ■,
Clear the voice address counter 19 and word counter 2o. The SET signal is output at the following timing (2), and the voice selection address signals (2) S16 to vSo are loaded into the voice address counter 19. i.e. X113000
” is preset and floated, and the output A of the address counter 19
16 to Ao are output as they are. That is, the memory 18 is addressed by x''3000n and outputs the 8-pit audio data D7 to D0 stored therein.

Furthermore, when the CNT signal is output at ■, it is ANDed with the CLK signal (411° oscillator not shown in the example) of the same frequency as that used to sample the audio data, and the signal is output to the address counter 19 and word counter 20. Input the UP signal. Therefore, the addresses of the memory 18 are modified one after another, and the audio data is successively transferred from the data bus D7 to
Output on D0. This digital audio data is DA-converted by the DA converter 21 and DAou as shown in FIG.
Restore an audio signal such as t. The waveform of this audio signal is smoothed into a vertical shape by the CR circuit at the subsequent stage, and then output as audio by the speaker 22. In other words, the name of the dish selected here is voiced as a code name in a tone such as "107"°.

On the other hand, the word counter 20 is a 10 or hexadecimal counter, and inputs a carry signal C1'LY to the microcomputer 14 every time it counts 10 or 16 pulses of the UP signal. The microcomputer 14 counts this and outputs and controls the CNT signal until the address counter 19 finishes outputting a predetermined sound, that is, until addressing the address X"3FFF" in this example. That is, word counter 20 is used to detect the end of data in memory 18.

Further, on the numerical display section 6, a dish name code °107' is displayed. The display is dynamic lighting based on the scan signals S04 to S00, and the display data is based on the segment signal S.
Output as @ q −9 @ q □.

Now, with the configuration as described above, it is possible to indirectly check whether the heating data has been read without error from the dish name code notified by voice and display. If roast balk I 107 @ is selected, '1
If there is a notification of 00 @, the user can immediately know that an error has occurred in reading the barcode, and can prevent malfunctions by redoing the panning operation.

Nao voice synthesis data “107° is X” 3000”~”
It is stored in consecutive addresses of 3FFF''.
1 "is X"1000" ~ "15FF", 10
a may be stored in X"0000" to "05FF" and 17@ in xl'700on-I'76FF", and these may be combined to synthesize '107'.

With this method, the number of audio data that requires a large amount of memory can be significantly reduced, and this audio data can also be used when notifying the time or one hour of a timer.

Also, if the pen-shaped pick-up is configured to scan the cooking water page as in this example, you can check the dish name code with your ears while following the cooking water barcode with your eyes, making it extremely easy to use. It also eliminates the hassle of losing your card and having to search for it. Note that if audio notification and display notification are combined as in this embodiment, it will be safe even if the audio is missed, but of course they may be provided separately.

Next, we will show an example of notifying the name of the dish by displaying it.
I'm faithful.

No. 6 shows an example in which a character display capable of displaying characters is used and display data is obtained from an external source (bar code), and FIG. 7 shows the code data.

The 26 letters of the alphabet are defined as shown in the table below. In other words, to represent 26 characters of the alphabet, 6 bits are required for each character.

Now, the read dish name code is displayed on the character display 23 after the same procedure as in the previous embodiment. The dish name is expressed by the full name instead of the code name, making it easy to confirm. This character display has 10 digits and is dynamically lit by scan signals SC9 to S00, and the display data is segment signal S@9.
It is output to 1a to 5eq0.

Note that in FIG. 3, the ts o / e o Hz signal is a pulse synchronized with the power supply frequency, and is used for counting by the timer control section. The two switches 24 are door switches that respond to the opening and closing of the door, one inserted into the main circuit and one inserted into the microcomputer. In this example, the timer decrement stops when the door is opened, so the 50/60
It is configured to cut off the Hz signal.

Effects of the Invention As described above, the heating device of the present invention has a barcode reader and can input heating data from the barcode on the cooking water, so by the simple operation of scanning the barcode with the barcode reader, Heating data can be easily set.

In addition, reading check data is placed within the barcode and sandwiched between the front and back of the heating data, so by inspecting this it is possible to determine whether or not the reading was successful. Therefore, if the input of heating data is successful, heating can be started, and if it is unsuccessful, an error notification can be issued and the user can be prompted to input again using the barcode reader.

Furthermore, the heating data is bound in the style of a cookbook, so unlike cards, it doesn't get lost or come apart, making it difficult to search.
