Abstract

PURPOSE:To enable simplification of memory cooking operation and for the user to easily confirm the contents of the cooking at each step by causing the memory device to store or call the contents of cooking consisting of one step or a plurality of steps by an operation of pushing keys. CONSTITUTION:When a memory entry key b is pushed after setting several steps of cooking information of data RAMs 1-3 25 is transferred to memory RAMs 1-3 26. In this case, if a start key input (c) is applied, cooking is executed by the user who looks at the information of the data RAM 25. When a memory recall key (e) is depressed, information is first sent from the memory RAM 1 to the data RAM 1, and a buzzer blows once (f) and the contents of the cooking at the first step are displayed by a display tube 5. If the cooking is set and stored up to the second step and the third step, the cooking contents in respective steps are successively displayed in the display tube 5 together with the buzzer sounds (g, h) responsive to the number of steps. The cooking information thus called is compared (j) with the temperature sensor information (i) to discriminate whether execution of cooking (d) is possible. If conditions are satisfied, it is determined that the cooking can be executed, and the start key (c) is depressed.

The microcomputer 21 judges the data obtained from the clock input section 2o and outputs a signal to the output control section 22 while controlling the time, causing the magnetron 23 to oscillate and displaying on the display tube 6 at the same time. In addition, the microcomputer 211-i sends a signal to the buzzer sound generator 24 to generate a buzzer sound in order to generate a notification sound.

FIGS. 4 and 5 are block diagrams showing the operation of the microcomputer 21 during the cooking process that is executed after the cooking is set.

FIG. 4 shows the case of normal cooking, and when the heating output, heating time, or heating temperature is input, the necessary information is stored in the data RAM 1 of the data RAM 25 in the microcomputer 21. If you set up to the second (2nd) step and the third (3rd) step, those data will be data R.
AM2. It is stored in data RAM3. When a series of cooking is set in this way and the start key 9 is pressed, the cooking starts from the contents of the data RAM 1, and then the data RAM 2. Data RAM3
Cook in this order.

FIG. 5 shows the case of memory cooking. After setting several steps of cooking, press the memory entry key 1° and the information in each data RAM 1 to 3 of the data RAM 25 will be transferred to the memory RA.
It is transferred to each memo IJ RAM 1-3 of M26.

If the start key 9 is input here, the data RAM 2
Check the information in step 5 and start cooking. When the memory recall key 11 is pressed, first the memo IJ RAM 1
The information is sent to the data RAM 1, the buzzer sounds once, and the cooking contents such as the cooking output of the first (1st) step, cooking time, and cooking temperature are displayed on the display tube 6. Second (
2nd) step, cooking is set up to the 3rd (3rd) step.

If stored, the cooking contents of each step will be sequentially displayed on the display tube 5 together with the number of buzzer sounds corresponding to the step. The cooking information thus called up is compared with the temperature sensor information to determine whether or not cooking can be executed, and if the conditions are met, it is determined that cooking can be executed, and the start key 9 is accepted.

Next, its operation will be explained based on the above configuration. The user first sets the cooking sequence using the power key 6 and the time key 7. The heating data was stored in the data RAM 25 in the microcomputer 21, and cooking was set using this data.

FIG. 6(a) is a display example when the power is set to "3" and the heating time is set to "3 minutes". No. 3 of the output display sections 16 indicating the power lights up, indicating that the time is 130 minutes. Next, as the second (2nd) step, the power “1
", heating time 1-1 minute 20 seconds". Exit display section 16id shows power "1" and heating time of "1 minute 20 seconds" (Fig. 6(b)) 0th (3rd)
When the step is set to "power 2" and "heating time 16 minutes", No. 2 of the output display section 16 lights up and displays "heating time 16 minutes" (FIG. 6(C)). When the memory entry key 1o is pressed with the cooking sequence set in this way, the cooking data is transferred from the data RAM 25 to the memory RAM 2.
6 and returns to the display of the first (1st) step (
Figure 6(d)). The above is an example of a memory entry for time cooking, that is, cooking in which power and heating time are set.

In the case of temperature cooking, that is, cooking in which the power and temperature are determined and the object to be heated is heated until it reaches the set temperature, first, the temperature sensor 6 is set in the microwave oven, and the microcomputer 21 reads the data from the temperature detection section 18. , temperature sensor 6
When it is determined that the food has been sent, the display section 14 indicating temperature cooking lights up. Next, set the power and heating temperature respectively.

Select 8 to complete the setting.

FIG. 7 is a display example of a memory entry for temperature cooking. When setting the power "1" and the temperature "60°C" as the first (1st) step, No. 1 of the display section 14 and the display section 16 lights up, and "60°C" is displayed (No. 7 Figure (2L)). Next, when power "2" and temperature "80'C" are set in the second (2nd) step, the display sections 14 and 16 light up and "80'C" is displayed. 3rd (3r
d) Set Step Power]-3 "Temperature 1-95°C" (Figure 7 (C)) and press the memory entry key 10, the cooking data will be transferred in the same way as time cooking, and the display will be displayed. becomes the display of the first (1st) step (7th
Figure (d)).

Next, memory recall will be explained. To recall the cooking sequence memorized using the steps above,
Use memory recall key 11.

Let us take temperature cooking, which consists of the three steps mentioned above, as an example. When you press the memory recall key 11, the buzzer sounds once and the display tube 5
Among the memory cooking display section 15 and the step display section 17 indicating the currently recalled step, the one indicating the first (1st) step lights up, and the cooking contents of the selected first (1st) step are displayed. (Figure 8(a)). After 2 seconds, the buzzer sounds twice, and a display indicating the recall of the 2nd step and the contents of the cooking are displayed (Fig. 8 (b)).
After another 2 seconds, the recall of the 3rd (sra) step is 3.
This is done with a buzzer sound and a display (Fig. 8(C)). After another 2 seconds, the display returns to the 1st step (
Figure 8(d)). By the way, if the user recalls the memory without setting the temperature sensor 6 even though temperature cooking is set in memory, the memory RAM 26 in the microcomputer 21 contains temperature cooking, but the temperature sensor 6 is not set, sensor data is not input to the microcomputer 21. Therefore, the memory recall is activated and recalled, but the temperature sensor 6 starts to be reset and the start key 9
is accepted. Conversely, when recalling timed cooking with the temperature sensor 6 still inserted, the recall key 11 will be accepted, but if the temperature sensor 6 is about to be removed, the start key 9 will be pressed.
is not accepted.

As described above, according to this embodiment, by effectively using the RAM of the microcomputer 21, a microwave oven capable of memory cooking without complicated operations can be obtained.

Effects of the Invention As described above, according to the present invention, the following effects can be obtained.

(1) Memory entry and memory recall can be operated with one key, and no troublesome operations are required to perform memory cooking, which is particularly effective for frequently used menus.

(2) The memory cooking content can be reliably confirmed by the number of buzzers and the display, so it is safe and prevents cooking errors. (3) During memory cooking, the microcomputer uses the information from the temperature sensor and the data RAM.
