The present invention relates to an apparatus and a method for allowing a user to arbitrarily modify a cooking time in performing a high speed cooking (JET-START) function in a microwave oven. The key control unit includes a JET-START time adjusting key. The present invention relates to a user program apparatus and method for a microwave oven that enables a microwave operation of a user's convenience by decoding a key operation information and resetting a cooking time according to the decryption result.

In the conventional microwave oven, as shown in FIG. 1, a microcomputer 1 performing cooking control, a power supply circuit 2 for supplying power to each circuit including the microcomputer 1, and a driving unit including a magnetron A relay driving unit 3 and an output unit 4 for controlling the operation, a door circuit 5 and a door driving unit 6 including a safety switch, a display driving unit 7 and a display unit 8 in which a function display is performed, It is composed of a key control unit 9 for providing cooking settings and operation information to the microcomputer 1, and the operation during JET-START cooking is as follows.

When the user selects and operates one key from the J-START key (30 seconds, 1 minute, 3 minutes) of the key control unit 9, the microcomputer 1 decrypts the operation information and displays the cooking time according to the decryption result. The display unit 8 is displayed through the drive unit 7 and the output unit 4 is driven through the relay drive unit 3 to automatically cook and end the food in the heating chamber at the selected time and microwave level.

However, according to the conventional microwave oven, the type of JET-START cooking is set at a fixed time (30 seconds, 1 minute, 3 minutes), and this time cannot be changed arbitrarily by the user. In case of insufficient or excessive cooking time, if cooking time is insufficient, the cooking should be repeated again. If cooking time is excessive, the user must monitor the cooking progress and operate the stop key in the meantime, so automatic cooking is impossible. There was a problem that the inconvenience caused by the microwave oven operation.

The present invention allows the user to arbitrarily adjust the cooking time for each key through the J-START key operation provided in the key control unit, and during cooking, the microcomputer decodes the key operation information and automatically cooks the preset cooking time. It is an object of the present invention to provide a user program device and a method for providing convenience to the operation of the microwave oven by performing the present invention. Referring to FIG.

Micom 11 for resetting the cooking time by decoding the JET-START time correction key (J-START 1, 2, 3) operation information of the key control unit 10, and performs automatic cooking with the reset cooking time, and each, A power supply circuit 2 for supplying power to the circuit, a relay driver 3 and an output unit 4 for controlling a driver including a magnetron, a door circuit 5 and a door driver 6 including safety switches; And the display driver 7 and the display unit 8 in which the function display is made, and the time correction keys J-START1, 2 and 3 for supplying the microcomputer 11 with information for correcting the JET-START cooking time. The key operating portion 10 includes a key J-START.

On the other hand, in the user program method of the present invention by the microwave oven, as shown in FIG. 3, when the key information is inputted by determining whether or not the correction input key (J-START) is operated, the time correction key (J-START1) , 2,3), and if the time correction key (J-START1, 2, 3 is operated, the user decodes the information after the numeric key is manipulated and stored as time information, and then the correction input key ( When J-START) is turned on, the JET-START cooking time is changed by changing the cooking time corresponding to the time correction keys (J-START1, 2, 3), which are manipulated with the time of the numeric key information. Referring to Figures 2 and 3 to set the change will be described the JET-START cooking time program process according to the present invention as follows.

First, in the microcomputer 11, a memory M1 in which the changed time information is temporarily stored, and flags F1 to F5 indicating whether or not each key is operated are defined.

Flag 1 (F1) is set upon input of the correction input key (J-START), flag 2 (F2) is set on input of the time correction key (J-START1), and flag 3 (F3) is set on time correction. Set at the input of key J-START2, flag 4 (F4) is set at input of time correction key J-START 3, and flag 5 (F5) at set of JET-START data input. .

First, the initial state is automatically cooked for a predetermined time (default time) by one-touch as in the prior art, and the change of the JET-START cooking time is changed as the user operates the key control unit 10. When the power is turned off, it returns to the default time.

To modify the cooking time, when the user turns on the correction input key (J-START), the microcomputer 11 decrypts the key operation information and sets the flag 1 (F1), and then the user changes the time correction key (J-START1, When the key desired to be corrected in time is turned on in 2, 3, the microcomputer 11 decrypts the key operation information and sets the flag F2, F3, F4 of the operated key.

Subsequently, when the user sets the desired time by operating the numeric keys of the key control unit 10, the time information input to the microcomputer 11 is stored in the memory M1, and when the correction input key J-START is turned on, the flag ( The set state of F2, F3, F4 is searched and updated by changing the cooking time of the time correction keys J-START1, 2, 3 corresponding to the set flag to the time information of the memory M1.

Thereafter, when the time correction keys (J-START1, 2, 3) are turned on, the relay driving unit 3 and the output unit 4 are driven and controlled by the updated cooking time to perform automatic cooking and end.

3 shows a process in which the microcomputer 11 updates the cooking time while searching for the set of the flags F1 to F5 as described above.

That is, if key input information of the correction input key (J-START) is determined and input, the data input flag F5 is set.

If the result of the discrimination is set, the corresponding flag F2, F3, F4 is searched to determine which key is the key among the time correction keys J-START1, 2, 3.

If the flag and 2 (F2) are set, the cooking time data corresponding to the time correction key (J-START1) is changed to the cooking time data of the memory M1, and all the flags F1 to F5 and the memory M1 are cleared. . If the flag 3 (F3) is set, the cooking time data corresponding to the time correction key (J-START2) is changed to the cooking time data of the memory M1, and all the flags F1 to F5 and the memory M1 are cleared. . If the flag 4 (F4) is set, the cooking time data corresponding to the time correction key (J-START3) is changed to the cooking time data of the memory M1, and all the flags F1 to F5 and the memory M1 are cleared. . On the other hand, when the time correction key (J-START) is input, it is determined whether or not the data input flag 1 (F1) is set. If it is set, the flag 2 (F2) of the time correction key (J-START 2) is set. If it is reset, the flag 2 (F2) is cleared and ends.

Even if the time correction key (J-START2) is input, if flag 1 (F1) is set, set flag 3 (F3) of the time correction key (J-START2), and if it is reset, set flag 3 (F3). Clear it and exit.

Even if the time correction key (J-START3) is input, if flag 1 (F1) is set, set flag 4 (F4) of the time correction key (J-START3), and if it is reset, set flag 4 (F4). Clear and exit.

On the other hand, if the flag 1 (F1) is set when the numeric key is input, the input data is stored in the memory (M1) as time information and the input data flag 5 (F5) is set and terminated. The cooking time can be changed in response to the flag search. As described above, according to the present invention, when the user performs the JET-START cooking function in a microwave oven, the user can change the cooking time arbitrarily and perform one-touch automatic cooking, which is convenient and prevents bad cooking. It can increase the reliability of the product.
