The present invention relates to an automatic cooking apparatus of a microwave oven, in particular, when the cooking state of the completed auto-cooking is poor, the user inputs the currently completed automatic cooking state into the microwave oven, and the next cooking state desired by the user is cooked. It was made possible.

In the conventional microwave oven, as shown in FIG. 1, the switching element 2 controls the on / off control so that the AC power output from the power supply unit 1 is supplied to the high voltage generator 3, and the input power is controlled by the input power. A high voltage generator 3 for outputting a high voltage capable of oscillation, a magnetron 4 for generating a high frequency such that the food 6 in the microwave heating chamber 5 is cooked by the output high voltage, and a food matter by the generated high frequency (6) a sensor unit 7 for detecting steam evaporation, temperature change and gas generation generated during cooking, a detector unit 8 for detecting a signal detected by the sensor unit 7, and a user's heating chamber ( 5) a key input unit 9 provided with a cooking menu selector 9A for applying a signal to select the food 6 to be cooked, and an input key signal and a sensor signal detected by the detection unit 8. My to control the switching element 2 by the comparison result To consist of 10, 11 is a unit AC / DC conversion.

On the other hand, the microcomputer 10 is composed of a ROM 10A in which cooking-related data is stored, a CPU 10B for performing calculation and control functions, and a RAM 10C for temporarily storing cooking data.

In the microwave oven configured as described above, as shown in FIG. 1, the user first selects the food 6 to be cooked in the heating chamber 5 through the cooking menu selection unit 9A in the key input unit 9, and then cooks. To start, the switching element 2 applies the AC power output from the power supply 1 to the high voltage generator 3 to generate a high voltage capable of oscillation.

Therefore, when the high voltage generated through the high voltage generator 3 is applied to the magnetron 4 to oscillate high frequency, the food 6 in the heating chamber 5 is cooked.

At this time, the sensor unit 7 detects vapor evaporation, temperature change, and gas generation generated during cooking of the food 6 and applies it to the microcomputer 10 through the detection unit 8.

The sensing signal input as described above is compared with cooking-related data stored in the ROM 10A by the CPU 10B in the microcomputer 10, and the cooking-related value in which the sensing signal value of the input sensor unit 7 is stored in the ROM 10A. If the data is the same, the microcomputer 10 cuts off the power supplied to the magnetron 4 controlling the switching element 2 to complete cooking of the food 6 in the heating chamber 5.

However, in the conventional microwave oven, when the user inputs the optimum automatic cooking data into the ROM 10A in the microcomputer 10 and cooks the food 6 in the heating chamber 5, the food 6 may be changed by the user's taste and container selection. In the case where the automatic cooking state is poor, the user has a problem in that the cooking data stored in the ROM 10A in the microcomputer 10 cannot be corrected to improve the problem.

In order to solve such a conventional problem, the present invention, when the cooking state of the food is completed auto-cooking is poor, the user re-enter the current auto-cooking state completed in the microwave oven.

That is, the purpose of the user to perform the automatic cooking according to the user's taste by re-input or decrease the cooking time or the output level to explain the configuration and effect of the present invention by the accompanying drawings as follows. .

First, the present invention microwave oven, as shown in Figure 2, the switching element 22 for switching on / off so that the AC power output from the power supply unit 21 is supplied to the high voltage generator 23, and the supply A high voltage generator 23 for outputting a high voltage oscillable by the switched power supply, and a magnetron 24 for generating a high frequency so that the food 26 is cooked in the heating chamber 25 of the microwave oven by the output high voltage. The sensor unit 27 detects vapor evaporation, temperature change and gas generation generated when the food 26 is heated by the high frequency generated by the magnetron 24, and a detector detecting the signal detected by the sensor unit 27 ( 28) and a key input unit 29 for selecting a food 26 to be cooked by the user through the heating chamber 25 of the microwave oven and re-inputting the result of cooking at the time of cooking, and detected by the detection unit 28. Heating chamber by comparing sensor signals The cooking result data to be re-input output from the key input unit 29 by the microcomputer 30 for controlling the switching element 22 to complete cooking of the food 26 in the 25 and the control signal of the microcomputer 30. It consists of an EEPROM 31 which stores a signal, and 32 is an AC / DC converter.

Meanwhile, the key input unit 29 allows the user to input the cooking result of the cooking menu selection unit 29A for selecting the food 26 to be cooked through the heating chamber 25 and the cooking result of the selected food 26. A display unit 29B for displaying whether or not input, a re-input key unit 29C for re-input of the auto-cooking result by the signal displayed on the display unit 290B, and a time for inputting the re-input auto-cooking result The time input key part 29D is comprised.

In addition, the microcomputer 30 includes a ROM 30A in which cooking-related data is stored, a CPU 30B for performing calculation and control functions, and a RAM 30C for temporarily storing calculation data output from the CPU 30B. It is composed.

The effects of the present invention configured as described above will be described with reference to FIGS. 2 and 3.

First, when the user selects the food 26 to be cooked in the heating chamber 25 through the cooking menu selection unit 29A in the key input unit 29, and starts cooking, the switching element 22 supplies the power supply unit 21. A high voltage is generated by applying the AC power output from the high voltage generator 23 to the magnetron 24 to oscillate a high frequency so that the food 26 in the heating chamber 25 is heated.

At this time, when the high frequency is oscillated, the sensor unit 27 detects water vapor evaporation, temperature change, and gas generation generated when the food 26 is heated, and is applied by the detection unit 28 to the RAM 30C in the microcomputer 30.

In this way, the sensor signal value input to the RAM 30C in the microcomputer 30 is compared with the time setting value A which is cooking related data stored in the ROM 30A by the CPU 30B.

As a result of the comparison, when the input signal value reaches the time set value A stored in the ROM 30A, the microcomputer 30 controls the switching element 22 to turn off the magnetron 24, thereby causing the food in the heating chamber 25 to be turned off. (26) Complete cooking.

Subsequently, in response to the display of the display unit 29B which asks whether to re-enter the automatic cooking result of the food 26, the user checks the state of the food 26 that has been automatically cooked, and the " Reduce cooking time "," Good cooking time "," Add cooking time "key.

Selection result If the automatic cooking result of the currently completed food 26 is "good", turn off the display unit 29B displaying whether the automatic cooking result is re-input, and then set the compensation time value B to the ROM 30A before cooking time. Keep it at the set value (A).

On the other hand, if the automatic cooking result of the currently completed food 26 is not "good", turn off the display unit 29B displaying whether the automatic cooking result is re-input, and then turn on the time input key unit 29D to turn on the currently completed automatic cooking. Adjustment request time value Enter).

At this time, when the time input starts, if the time input is turned off after the key unit 29D is turned off, and the re-entry key unit 29C selects the "reduce cooking time" key according to the automatic cooking result, The compensation time value B corresponding to the signal of the key is added to the adjustment request time value α from the pre-cooking time setting value A set in the ROM 30A in the microcomputer 30.

In addition, when the re-input key unit 29C selects the "add cooking time" key according to the automatic cooking result, the ROM value in the Marscum 30 is set to the compensation time value B according to the signal of the "add cooking time" key. The adjustment request time value α is added to the pre-cooking time set value A set at 30A.

Therefore, the added and subtracted compensation time value B and the compensation time value B in the "good" state are calculated by the CPU 30B in the microcomputer 30 to maintain the cooking time set value A. The time value (B) is changed to the time setting value (A) and stored in the EEPROM (31) so that the user can cook the next food (26) using the time value stored in the EEPROM (31) according to the user's taste. Cooking will be completed.

As described above, if the result of checking the cooking status of the completed food cooking is bad, the user re-inputs the cooking time and output level of the added / subtracted food according to the result of automatic cooking of the currently completed food. The cooking of the food according to the user's taste is completed so that the reliability of the product is improved.
