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.

Conventional technology In heating devices such as ovens and microwave ovens, sequence heating by repeating a plurality of different heating patterns is often useful. For example, when cooking roast balk in a microwave oven, H1G is used in the first step.
Heat at H power (eooW) for 10 minutes, then in the second step switch to LOW power (200W) and heat for 26 minutes.

Finally, in the third step, the temperature is set to MEDium (40Qw) and final heating is performed for 60 seconds.

The operating procedure for setting such sequence heating using a conventional heating device will be explained. FIG. 4 is a perspective view of the main body of an example of a conventional heating device, and FIG. 6 is a detailed view of the operation panel thereof.

The operation panel 2 provided on the front of the main body 1 has an output key 3 for selecting the output, and indicator lights 4 and 10 for displaying the output.
Numeric keys 6, a four-digit numeric display section 6 for displaying these, 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 for cooking roasted balk using such an operation panel is as follows.

Problems that the invention aims to solve: However, with this configuration, unless 13 keys are pressed,
Unable to set heating sequence. During this time, you will have to delete it and start over again.

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 has been input correctly.

■ Cards are easily lost. Also, it is difficult to search because it is broken up into pieces.

First, to explain about ■, in the example of the 3-step sequence addition described above, 13 keys are operated, but assuming that each key information is expressed as a 4-bit binary code, 6
The amount of data is 2 bits.

In other words, if each key is coded as shown in the table below, an example of roast balk will be 62-bit data as shown below.

” 1 01 0-0001 -0000-0000
-〇〇〇-1011-0010-0101-oooo
@.

In an actual example, a parity check is included to prevent reading errors, so in an example of 3-step sequence heating, the number is usually around 80 bits. Since a large amount of data is picked up one bit at a time using a pickup such as a magnetic head, there is a high possibility that a reading error will occur.

Naturally, two or more combined errors that escape the parity check may also occur.

■ is related to ■, but it is difficult to tell whether the card data has been entered correctly into the main unit.

There is no reliable method other than checking the display one step at a time by the user himself. This reduces the meaning of automatic settings in half.

(2) is a drawback because the information medium is a card. This can be said to be a disadvantage of its ease of handling.゛In view of this background, the present invention realizes a heating device that can easily set sequential heating data with a large amount of data, has little fear of incorrect settings, and is equipped with an input device that does not dissipate like a card. It is something.

Means for Solving the Problems The heating device of the present invention has a bar code league and is used for a cookbook bound in the form of a book and for each page in which each dish of the cookbook is described. It consists of a barcode printed or pasted with sequential heating data corresponding to the dish.

Function: The heating device of the present invention can input sequential heating data from the barcode printed on the cookbook using the barcode reader, so the simple operation of scanning the barcode with the barcode reader can eliminate complicated Heating data can be easily and accurately set. Also, heating data is not dissipated like with cards.

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 as with the conventional example shown in FIG. 6, there are three control panels for manual settings. Output key 3, 10 number keys 5, start key 7, clear key 8. Numeric display section 6 (not shown).

It is equipped with an output indicator light 4. Reference numeral 9 denotes a pen-shaped pickup, which is equipped with a magnetic head or an optical head at its tip, and reads out predetermined data by scanning the bar code 1o. In the test code 1o, a code name representing a heating sequence for each menu and heating sequence data are recorded in binary numbers. If an 8-bit barcode is used, 266 menus can be coded, and even if all the menus published in Cookbook 11 were coded, the amount of data would increase by a very small amount.

FIG. 2 shows an example of the barcode, in which heating sequence data is sandwiched with a heating sequence name code. In other words, by placing sequence name codes unrelated to control data before and after the most important heating sequence data, whether or not the head has correctly read the data can be confirmed by checking the coincidence of the codes before and after the data. Furthermore, this sequence name code is sent back to the user by a notification means such as display or speech synthesis.
Depending on whether or not this is a predetermined code, the user can indirectly know whether the heating sequence data located in the middle has been correctly read. Note that the first code is a standby code to prepare 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 microcomputer 140.

is input to. 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 transferred to the microcomputer 14.
Store it in internal RAM. 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"6B" matches. If they do not match, an error has occurred due to the head 12 coming off the barcode 10 during the reading process, and of course there is an error in the middle. The located heating sequence data is also questionable, and in this case, an error message is displayed and the user is prompted to read out the data again using the pen-shaped pickup.

If the heating sequence name codes match, it means that the reading by the head was successful, and it can be said that the reading reliability of the heating sequence data located in the middle is high. Further, although the example shown in FIG. 4 does not include a parity check, if a parity check function is added to this, the reliability of reading the heating sequence data can be said to be perfect.

Next, this heating sequence data is transferred to a predetermined address in the storage section (RAM in this embodiment). That is, the heating sequence is preset in the control register section that performs output control and timer control.

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 times.

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 unit that controls heating time based on data written in a timer control register in the RAM.

The heating sequence name code is provided by a notification means such as a synthesized voice or a display.

To make such notification by display, for example, "Roast Balk" in Figure 1 should be given the code name "107" (serial number).
If so, a method of displaying the code name 1106'' on the numerical display section 6 as shown in FIG. q −3e
Output as go.

In addition, a character display may be used to directly display the menu name, and it is also possible to use synthesized speech instead of the display.

Effects of the Invention As described above, the heating device of the present invention has a six-code reader and can input sequential heating data from the barcode printed or pasted on the cookbook. Complicated heating data can be easily and accurately set by a simple scanning operation.

In addition, if a heating sequence name code is placed in the barcode and the configuration is configured to notify this, the operator can immediately determine whether or not the heating data input by the barcode reader was successful, and the input heating There is no need to check the data one stage at a time.

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.
