(B) Conventional Technology In recent years, electronically controlled microwave ovens that include a control unit such as a micro computer and can perform various controls have been commercialized.

Some of such microwave ovens have a storage unit having a plurality of storage areas capable of storing food heating information for each cooking, as seen in Japanese Patent Laid-Open No. 54-47144. In that case, the food heating information can be easily set by reading the food heating information stored in advance in the storage area of the storage unit without the trouble of setting the food heating information by complicated operation each time. it can.

Here, regarding the storage of the food heating information in the storage area of the storage unit, regardless of whether other food heating information is already stored in the corresponding storage area, the food heating information is newly stored in the corresponding storage area. When the operation for storing the information is performed, the food heating information is surely newly stored in the corresponding storage area. That is, when another food heating information is already stored in the corresponding storage area, the already stored food heating information is erased.

Therefore, when the new food heating information is stored, if the operation for storing the new food heating information in the storage area in which the food heating information that is not desired to be erased is already stored is mistakenly operated, it is deleted. There is a drawback in that undesired food heating information is undesirably erased.

(C) Problems to be solved by the invention In the case where an operation for storing new food heating information in a storage area in which other food heating information that is not desired to be erased is already stored is mistakenly performed, It is desirable to prevent undesired deletion of other food heating information that is already stored and is not desired to be deleted.

Read the food heating information from the storage area based on the operation,
In an electronically controlled cooker having a control unit for driving and controlling the heating energy supply means according to the food heating information to perform cooking, the control unit is divided into the corresponding storage areas according to an instruction from the storage key. It is judged whether the food heating information of is already stored, and if it is not stored, the food heating information is stored, and if it is stored, the food heating information is not stored in the corresponding storage area. In addition, the notification means is instructed to notify that the other heating information is stored in the corresponding storage area.

(E) Action Whether or not the food heating information already stored in the corresponding memory area is not desired to be erased, the already-stored food heating information is newly added to the corresponding memory area. It is possible to prevent the food heating information from being undesirably erased based on an operation of storing the food heating information, and to notify that the food heating information is already stored in the corresponding storage area.

(F) Example A microwave oven according to an example of the present invention will be described below with reference to the drawings.

FIG. 1 shows the appearance of the microwave oven, in which a microwave heating chamber (2) is arranged in the microwave oven main body (1), and a front opening (3) of the heating chamber is opened and closed by a door (4). It
Further, a display section (6) as a notification means and a key operation section (7) are provided on the right front surface of the main body (1) and the panel (5).

FIG. 2 shows the details of the key operation unit (7), in which the numeric keys 0 to 9 and various function keys are provided. For this function key,
A time key for setting the heating time, an output key for setting the heating output, food heating information such as these heating time and heating output, etc.
A storage key for storing in an internal storage area (described later),
There are a cooking number key, a cooking start key, an erasing key, and the like, which are read keys for designating the storage area. The numeric keys, time key, and output key constitute information input keys for inputting food heating information.

FIG. 3 shows the circuit of the microwave oven. The microwave oven is controlled by a micro computer (8) as a control unit. That is, the computer controls the display on the display unit (6) based on the information from the key operation unit (7),
Moreover, the output of the heating signal H is controlled. When the heating signal H is output, the switching circuit (9) composed of a bidirectional thyristor is turned on, power is supplied from the commercial power supply (10) to the high voltage circuit (11), and high voltage is supplied to the magnetron (12). The microwave is supplied as heating energy into the heating chamber (2) to heat the food.
Further, the microcomputer (8) writes to a RAM (read only memory) (13) as a storage unit,
Read control is performed. The RAM is backed up by means (not shown) so that the stored contents will not be erased when the power is cut off.

FIG. 4 shows the details of such a RAM (13). The RAM (13) has a plurality of storage areas (14), (14), ... And each storage area (1
4), (14), ... Correspond to each cooking and store food heating information for each cooking. There are, for example, 50 such storage areas (14), (14), ....

FIG. 5 shows a flow chart of the operation program of the microcomputer (8), and the operation of the microwave oven will be described below along the chart.

When the microwave is turned on, the program cycles through S1 to S2 to S5 steps. The S1 step initializes the micro computer (8), the S2 step detects the key operation on the key operation part (7), and the S3, S4, and S5 steps detect the cooking number based on the detection at the S2 step. It is determined whether the key, the memory key, or the cooking start key has been operated.

Thus, for example, when performing cooking consisting of a first stage for heating for 2 minutes at a heating output of 70% and a second stage for heating for 4 minutes at a heating output of 50%, first, information on the heating of the two-stage food for such cooking is performed. That is, 70%, 2 minutes (for the first stage) and 50%, 4 minutes (for the second stage) are set by the following key operations.

Based on such key operation, the food heating information is sequentially set in the microcomputer (8) at the circulating S2 step.

After that, the cooking start key is operated. When such a key is operated, the program exits the circulation at S5 step and goes to S6 step. In the step, cooking is performed according to the food heating information. First, as the first stage, the heating signal H is output for 7 seconds at a cycle of 10 seconds for 2 minutes, and then the heating signal H is output for 5 seconds at a cycle of 10 seconds for 4 minutes as the second stage. Thus, microwave heating is controlled and desired cooking is performed. When such cooking is complete, the program returns to step S1 and then cycles through steps S2-S5.

Next, a case will be described in which the food heating information stored in one storage area (14) of the RAM (13) is read out and desired cooking is executed according to the information. Here, cooking numbers 1 and 2 are stored in the storage areas (14), (14), ... Of the RAM (13).
…, It is attached like 50. In this case, if the food heating information of the desired cooking is stored in the storage area (14) with the cooking number 5, the key operation on the key operation unit (7) is as follows.

First, if you operate the cooking number key, the program
The circulation of ~ S5 step is taken off by S3 step, and S7 and S8 steps are circulated. The S7 step is the same as the S2 step, and in the S8 step, it is determined whether or not the cooking start key has been operated based on the detection in the S7 step.

Then, when the number key 5 is subsequently operated, the number 5 is set, and when the cooking start key is subsequently operated, the program S
7. The circulation of S8 step is removed at S8 step to reach S9 step. In the step, cooking number 5 in the RAM (13) above
The food heating information stored in the storage area (14) marked with is read into the microcomputer (8), and the above-described control is performed according to the information to perform the desired cooking. When such cooking is complete, the program returns to step S1 and then cycles through steps S2-S5.

Next, the storage areas (14), (14), ... Of the RAM (13).
The case where the above-mentioned two-stage food heating information is stored in one of them will be described. If the storage area (14) with the cooking number 16 is vacant and the above information is to be stored in the area, the key operation section (7) operates the keys as follows.

First of all, if you operate the memory key, the program will execute the above S2 ~ S5.
The circulation of the step is removed by the S4 step, and the S10 and S11 steps are circulated. S10 step is the same as S2 step, S
In step 11, it is determined whether or not the memory key has been operated based on the detection in step S10. After that, when the subsequent key operation is performed and the memory key is finally operated again, the program exits the circulation of the above S10 and S11 steps at S11 step and reaches S12 step. In the step, it is judged whether or not another food heating information is already stored in the storage area (14) to which the set cooking number is attached. In the present case,
Since the storage area (14) with the set cooking number 16 is free, the program then goes to S13 step.
In this step, in the storage area (14) numbered 16
The above-mentioned two-stage food heating information, that is, for the first stage
70%, 2 minutes and 50% for the second stage, 4 minutes are stored in sequence. The program then returns to S1 step and S2
~ Cycle S5 steps.

By the way, when storing the two-stage food heating information in the storage area (14) with the cooking number 16 attached, the two-stage food heating information is stored in the storage area (14) with the cooking number 20 accidentally attached. The case where the operation is performed will be described. Here, it is assumed that another food heating information is already stored in the storage area (14) with the cooking number 20. The key operation on the key operation unit (7) in this case is as follows.

Then, when these keys are sequentially operated, as can be seen from the above description, the program circulates S2 to S5 steps, and circulates S10 and S11 steps, and then reaches S12 step in the same manner. However, in this case, the set cooking number 20
Since the storage area (14) marked with has already stored the other food heating information, the program stores it thereafter.
S14 step without reaching S13 step. In the step, in order to inform the cook that the other food heating information is already stored in the storage area (14) and what the information is, the above-mentioned The stored food heating information is read and the contents thereof are sequentially displayed on the display unit (6). That is, in this case, in the storage area (14) with the cooking number 20, the first stage for heating at 100% heating output for 1 minute, the second stage for heating at 30% heating output for 5 minutes, and the subsequent heating output. Assuming that the stage food heating information regarding cooking including the third stage of heating at 10% for 6 minutes is stored, "100%", "1 minute", "30" are displayed on the display unit (6).
"%", "5 minutes", "10%", and "6 minutes" are repeatedly displayed every few seconds.

The program then cycles through the S15, S16 and S17 steps. S15 step is the same as S2 step, S16 and S1
In step 7, it is determined whether the erase key and the memory key have been operated based on the detection in step S15.

Here, when the cook easily finds out that he made an erroneous operation based on the sequential display on the display section (6) and operates the delete key on the key operation section (7), the program causes the circulation of the steps S15 to S17 to be repeated. It leaves at S16 step, returns to S1 step, and then cycles through S2 to S5 steps. Then, the correct operation may be performed again.

In this case, when the cook sees the sequential display and decides that the previously stored three-stage food heating information may be deleted, the cooked storage number 20 that is erroneously operated is attached to the storage area (14).
In order to store the above-mentioned two-stage food heating information as it is, it is sufficient to further operate the memory key in the key operation unit (7). When the memory key is operated, the program goes out of the cycle of steps S15 to S17 at step S17 and goes to step S18. In the step,
Storage area (14) with the cooking number that was mistakenly operated
The desired food heating information, in this case the two-stage food heating information, is stored after the previously stored food heating information is erased. The program then returns to the S1 step and cycles through the S2 to S5 steps.

Although the RAM (13) is separate from the microcomputer (8) in this embodiment, it may be provided inside the microcomputer (8). Further, in the above program, the display section (6) appropriately displays the heating time, the heating output and the like.

(G) Effect of the Invention According to the present invention, when an operation for storing food heating information in the storage area of the storage unit is performed by the operation unit, another food heating information is already stored in the corresponding storage area. Is stored, the control unit does not store the food heating information in the corresponding storage area, and therefore another food heating information that is not desired to be deleted is already stored in the corresponding storage area. However, even if an erroneous operation to store new food heating information is performed, the above-mentioned other food heating information that does not want to be erased and is not undesirably erased, and is already stored in the corresponding storage area. Since the notification means notified that different food heating information is stored,
The cook can easily recognize the erroneous operation.
