The storage area I of the second group has a larger storage capacity than the storage area a41 of the first group, and the storage area a41 of the third group has a larger storage capacity than the storage area 141 of the second group.

And the first, second... 6th group storage area a4).

I, . . . can store single-stage, two-stage, and five-stage food heating information, respectively. These single-, two-, and three-stage food heating information are in the form described above.

FIG. 5 shows a flowchart of the operation program of the microcomputer (8), and the operation of the microwave oven will be explained below with reference to the same chart.

When the power of the microwave oven is turned on, the progera cycles through steps 82 to S5 through step ΔS1. In the S1 step, the microcomputer (8) is initialized, and in the S2 step, the key operation section (
The key operation at 7) is detected, and the key operation at 83. In steps S4 and S5, it is determined whether the memory key, continuation key, or start key has been operated based on the detection in step S2.

For example, when performing cooking that consists of a first stage of heating for 2 minutes at 0% heating cuff and a second stage of heating for 4 minutes at 50% heating output, first such two stages of cooking are performed. Food heating information.

namely 70%, 2 minutes (for the first stage) and 50%.

Set 4 minutes (for the second stage) using the following key operations.

Based on the key operations, the food heating information is sequentially set in the microcomputer (8) in the 82 steps during the circulation. .

Thereafter, a start key is operated, and when this key is operated, the program repeats the above cycle through 85 steps and reaches step S6. In this step, cooking is performed in accordance with the food heating information. First, as a first stage, the heating signal H is output for 7 seconds at a 10-second cycle for 2 minutes, and then as a second stage, the heating signal H is output for 5 seconds at a 10-second cycle for 4 minutes.

Thus, microwave heating is controlled and desired cooking is performed. When such cooking is completed, the program returns to step S1 and then cycles through steps 82-S5.

Next, a case will be described in which food heating information stored in one storage area (141) of the RAM (131) is read out and desired cooking is performed in accordance with the information.

Here, each storage area fi41.141 of the RAM circle,...
. is usually assigned a specific number, for example, the first group's storage area a41. fi41. ...is 11.12
．． 13. ... and the storage area of the second group (1
41,14], ... is 51.52.56. ..., and storage area a (a) of the 6th group, desk a... is 81.82.83. ... is attached.

And in this case, the food heating information for the desired cooking.

Assuming that the data is stored in the storage area a (a) of the second group numbered 51, the key operations on the key operation section (7) are as follows.

τ Eye Nose [i] Shoji First, when you operate the successive keys, the program starts from 82 above.
Breaking the cycle of S5 step at 84 steps and moving from 87 to S9
It will cycle through the steps.

S7 step is the same as S2 step, S8゜S9
In each step, the detection with S7 Steribu (based on two
It is determined whether a movement instruction key or a start key has been operated.

Then, if you press number keys 5 and 1 in sequence, number 5 will appear.
1 is set and then the start key is operated, the program exits the f cycle of steps 87 to S9 at step 89 and reaches step 810. In this step, the RAM
(The food heating information stored in the storage area a41 numbered 51 in LJ is read into the microcomputer (8), and the above-mentioned control is performed according to the information to execute the desired cooking. When the cooking is completed, the program returns to step S1 and then cycles through steps 82 to S5.

Next, a second group of storage areas [141, fi41, which can store two-stage food heating information, of the RAMa3 described above.
, . . . will be explained below. Now the second group number 56
If the storage area (141) marked with is empty and the above information is to be stored in this area, the following key operations are performed on the key operation unit (7).

l]Domcn口Q G[Ql 5121111]1[
J1 Trouble Enclosure rpt! II Tian Liu Old Erm 1 time I First, when you operate the memory key, the program starts from 82 above.
The circulation of S5 step is removed from LS11.6 in 83 steps.
Cycle through 12 steps. Step 811 is the same as step S2, and step 812 determines whether the memory key has been operated based on the detection at step 811. after that.

When the next key operation is performed and the memory key is operated again at the very end, the program repeats the cycle of steps 811 and 812 above.
The process exits at step 12 and reaches step S13. In this step, the previously described two-stage food heating information is stored in the storage area (14) numbered 1 56.

That is, 70% and 2 minutes for the first stage and 50% and 4 minutes for the second stage are stored sequentially. The program then returns to step 81 and cycles through step 85 to S2.

Now, all storage areas of the 6th group 14), (14
In the state where food heating information is stored in 1°..., and on the other hand, food heating information is stored only in a part of the storage area 0°... in the second group, 6 stages of food heating are newly performed. When attempting to store information, and if there is a storage area in which 2-step food heating information is stored among the storage areas of the 6th group (141, a41...), such 2-step food heating information is stored. The first-stage food heating information is stored in a storage area where the second group of information is not stored, and the corresponding storage area of the third group is cleared and such area is used for new three-stage food heating information. Must be vacated.

In this case, the target storage areas in the second and fifth groups are numbered 58. Assuming that F13 is attached, the key operations on the key operation section (7) are as follows.

River N IfllllMl [[IEI (5) (8) Country Page First, when you operate the continuation key, the program will start from 82 to 85.
The cycle of steps is exited at step 84, and steps 87 to S9 are cycled. Then, by sequentially operating the number keys 8.5, the number 8 assigned to one of the storage areas of the 6th group will be displayed.
5 is set and then the movement instruction key is operated, the program exits the cycle of steps 87 to 89 at step 89 and reaches step S14. In this step, the two-stage food heating information in the storage area numbered 83 is transferred to the transfer register (8a) in the microcomputer (8). The storage capacity of the transfer register is large enough to store three stages of food heating information. [(S15
The step indicates the number of stages regarding information transferred to the transfer register (8a).

In this case, 2 is written to the first stage register (8b) in the microcomputer (8).

The program then cycles through 816,817 steps. The S16 step is the same as the S2 step, and 817
At step 816, it is determined whether the successive key has been operated or not based on the detection at step 816. Then, when you operate the successive keys again.

The program exits the cycle of steps 816 and 817 at step 817 and cycles through steps 818 and 819. 8
The 18th step is the same as the S2 step, and in the S19 step, it is determined whether the movement instruction key has been operated based on the detection in the 818th step.

Then, by sequentially operating number keys 5 and 8, the second
When the number 58 attached to one of the group storage areas is set and the movement instruction key is operated again, the program starts at 818. The cycle of step S19 is exited at step 819 and reaches step 820. In this step, 818.
Regarding the numbered storage area set during the cycle of 819 steps, the number of stages of storable information, in this case 2, is written to the second stage register (8C) in the microcomputer (8).

In the following step S21, it is determined whether or not the number of stages in the first and second stage registers (8,b) and (8c) is less than or equal to the number of stages in the latter. In this case, both stage numbers are the same, so the program then reaches 822 steps. In this step, the food heating information in the storage area 1; transfer register (8a) of the number set during the circulation of steps 818 and 819 is transferred. In this case, the food heating information in the transfer register (8a) is transferred to the storage area numbered 58.

Therefore, the information in the storage area numbered 83 is stored in the storage area numbered 58. Then, in the following 825 steps, 8
The storage area where the information stored in Step 22 was previously stored, in this case the storage area numbered 86, is cleared.

Here, in this embodiment, the storage area of the new 3-stage food heating information ζ2 number 86 becomes vacant. The six-stage food heating information can be stored in the storage area numbered 83 by following the operations described above. The program then returns to step S1 and cycles through steps 82-85.

Incidentally, in the above key operation, if the number key following the second successive key is mistakenly operated as 1.2, in this case the storage area numbered 12 corresponding to the number key will be targeted. Then, the number of stages of information that can be stored in this area is 1, so in this case it is determined that the 821st step is not successful, and the program reaches the 824th step. If this is not determined and the program reaches step 822, the storage area numbered 12 is for single-stage food heating information, so the above 2-stage food heating information that is to be stored in that area will be stored. Not all information can be memorized. and.

In step 824, an erroneous operation notification is made through appropriate means. The program then proceeds with the appropriate processing steps.

In this embodiment, the RAM (131) is separate from the microcomputer (8), but it may be provided within the microcomputer (8). Heating time, heating output, etc. are displayed as appropriate.

(G) Effects of the Invention According to the present invention, in a state where one piece of food heating information is stored in a storage area with a large storage capacity despite its small amount, the food heating information can be stored in an appropriate storage area as needed. When the food heating information is stored in a small storage area, the operation can be easily performed by resetting the food heating information, and an electronically controlled cooking appliance with high operability can be obtained.
