BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooking operation method of a microwave oven, and more particularly, to a cooking operation apparatus of a microwave oven, in which a software program is configured so that accurate cooking can be performed even by a simple key operation.

Conventionally, when the user cooks in the microwave, as shown in the following Tables 1 and 2,

TABLE 1

TABLE 2

(Table 1) shows the key operation procedure when cooking with P / L8 for 3 minutes, and (Table 2) shows the key operation procedure when cooking with P / L10 for 3 minutes. After pressing the time key, set the numeric key, and then press the P / L (Power Level) key again and press the numeric key corresponding to the P / L to program it. There was a lot of inconvenience that must be input, the present invention was devised to improve the above problems, and the user can configure the time and the P / L judging device and the time decoder inside the microcomputer of the microwave oven. Each time you press the key, the microcomputer detects it so that the correct cooking can be achieved by simple key operation. Referring to the drawings as follows.

1 is a detailed block diagram of a microcomputer controller of a microwave oven, in which one side of the microcomputer 1 is connected to a clock (power) circuit (2) and a keyboard circuit (3) and a power relay and a triac control circuit (4), respectively. And a power supply circuit 8 through the door signal sensing circuit 5, the display circuit 6, and the buzzer circuit 7 as the other axis of the microcomputer 1, respectively. The power supply circuit 8 is connected to the microcomputer 1.

Referring to the internal circuit of the microcomputer 1 in the block diagram according to FIG. 2, each terminal of the keyboard 9 is connected to the time and P / L determination device 10 inside the microcomputer 1, respectively. The time and P / L judging device 10 is connected to the time decoder 11 on one side thereof, and its output is applied to the time data memory 13 and to the P / L decoder 12 on the other side thereof. The output is applied to the P / L data memory 14, and the time data memory 13 and the P / L data memory 14 are connected to the output control device 18 via the cooking data storage memory 15, respectively. The operation is connected to the time counter 16 and the P / L counter 17, respectively. The operation state thereof will be described with reference to the block diagram of FIG. 2 and the flowchart of FIG.

First, when the user presses the key of the keyboard 9, the signal of the keyboard 9 is applied to the time and P / L determination device 10 of the microcomputer 1, so that the time and P / L determination device 10 Determining whether the numeric key is time data or P / L data according to the order of input is applied to the P / L decoder 12 having the time decoder 11 and the initial value 10, respectively.

According to the above, the time decoder 11 and the P / L decoder 12 output pre-stored data from the time data memory 13 and the P / L data memory 14 according to the respective signals thereof. 15), the time counter 16 and the P / L counter 17 operating according to the contents of the cooking data storage memory 15 are operated and applied to the output control device 18 to control the triac and the relay. It is to let.

According to the operation description described with reference to the embodiment is as shown in (Table 1) and (Table 2) below.

키이를 누르게 되면 마이크로 컴퓨터(1)는 P/L의 값이 P/L디코더(12)의 초기값, 즉 10으로 판단하여 전자레인지를 동작시키도록 한 것이다.Table 3 shows the case of cooking with P / L8 for 3 minutes and the key operation procedure.

When the key is pressed, the time of the microcomputer 1 and the P / L judging device 10 are judged as time (3 minutes), and again.

When the key is pressed, the time and P / L judging device 10 judges P / L8.

Press key to start cooking, and (Table 4) shows the key operation sequence when cooking with P / L10 for 3 minutes.

When the key is pressed, it is judged as time (3 minutes) as described above, and immediately after

When the key is pressed, the microcomputer 1 determines that the value of P / L is the initial value of the P / L decoder 12, that is, 10 to operate the microwave oven.

Therefore, as described above, the cooking operation method of the microwave oven according to the present invention is very easy to use even when simple cooking by operating the microwave as a simple key operation of 2 or 3 times to improve the reliability and efficiency of the product. It provides the advantage of

Claims (1)

In the microwave oven including the microcomputer 1, the key of the keyboard 9 is determined in accordance with the input order and the cooking time and P / L are determined by the P / L judging device 10 in the microcomputer 1. The time decoder 11 and the P / L decoder 12 are applied to the time decoder 11 and the P / L decoder 12. In the time decoder 11 and the P / L decoder 12, the time data memory 13 and the P / L data memory ( 14) A cooking operation apparatus of a microwave oven, characterized in that configured to output data stored in advance.
