The present invention relates to an emergency cooking method of a microwave oven, and more particularly, to an emergency cooking method of a microwave oven for setting an cooking time according to a user operating one key and performing an emergency cooking according to pressing a start key.

In a conventional microwave oven, when an urgent dish is to be cooked, the user must first press the urgent dish, press a number key corresponding to the cooking time, and then press a start key to perform cooking for a set time.

For example, when pressing the emergency cooking key → 3 → start key sequentially, emergency cooking was performed with the power level 100% for 3 minutes. Therefore, the user has to operate the key in three steps in case of emergency cooking, there is a problem such as troublesome and takes a lot of time.

The present invention has been made to solve the above-mentioned conventional problems, and when the user presses only the emergency cooking key without pressing the numeric keys, the cooking time is set to the pressing time of the emergency cooking key, In order to provide an urgent cooking method that allows the user to simply set an urgent dish by performing an urgent dish according to pressing, the purpose thereof will be described in detail with reference to the accompanying drawings.

1 is a circuit diagram showing the configuration of a microwave oven to which the emergency cooking method of the present invention is applied. As shown therein, the microcomputer 1 for controlling the overall operation of the microwave oven, the numeric keys 0-9, and various function keys. And a keyboard (2) for inputting a key signal to the microcomputer (1), a power supply (3) for supplying operating power to the entire microwave oven, and a reset for detecting reset. A reset detection unit 4, a door detection unit 5 which detects the opening of the door and inputs it to the microcomputer 1, and a frequency input unit 6 which detects a frequency of a power source and inputs it to the microcomputer 1; And a magnetron driver 7 comprising resistors R1, transistors Q1, diodes D1 and D2 and magnetron driving relays RL1 for driving the magnetrons under the control of the microcomputer 1, and the microcomputer. Resistor (R2) for driving the turntable, lamp and fan motor under control of (1). Drives the buzzer under the control of the turntable / lamp / fan motor driver 8 consisting of the R3, the transistor Q2, the diodes D3 and D4, the capacitor C1, and the relay RL2, and the microcomputer 1; Buzzer driver 9 and a display unit 10 for displaying the operating state of the microwave oven under the control of the microcomputer 1.

Here, the inside of the microcomputer 1, the key analysis unit 101, the counter 102, the subtractor 103, the adder 104, the comparison determination unit 105, the first memory unit 106, the second memory The unit 107, the display control unit 108, and the output control unit 109 are configured.

In the drawing description of FIG. 1, reference numeral B + denotes a power source.

In the emergency cooking method of the present invention applied to the microwave oven having such a configuration, as shown in FIG. 2, the microcomputer 1 determines whether the heating operation of the food is currently performed while the power source B + is applied. When the heating operation is performed, the display control routine is performed to display the operation state of the microwave oven on the display unit 10, and then the execution routine is performed.

If it is not currently operating, it is determined whether a key signal is input from the key input unit 2, and if a key signal is input, it is determined whether it is a signal of a function key or a number key of 0-9. If the signal is 0, the data storage routine is executed to store the signal of the input numeric key, and the display control routine and execution routine are executed.

If the input key signal is a signal of a function key, the first storage unit 106 and the comparison determination unit 105 determine whether the current urgent cooking bit is in a set state, and if it is not in a set state, a signal of a function key. Determine if it is.

At this time, if the input key signal is the start key signal, the operation bit is set, the emergency cooking bit is reset, the error detection routine is executed to determine whether the error is performed, the display control routine and the execution routine are executed, and the clear key. In case of signal, it executes clear routine to clear all stored data and then executes display control routine and execution routine.In case of signal of stage key, it performs stage number analysis routine to analyze stage number and then executes display control routine and execution. Run the routine.

If the signal of the input function key is the signal of the emergency cooking key, the emergency cooking bit is set, and if the emergency cooking bit is set for a set time, for example, 100 msec, 1 is added to the memory M1. When the value of the memory M1 becomes 3, 0 is stored and cleared in the memory M1, for example, 30 seconds is stored in the memory M2, and the value of the memory M2 is determined. Determines if the bit is set.

At this time, if the 10-minute bit is not set, it is determined whether the value of the memory M2 is 10 minutes, and if the 10-minute bit is set, the 10-minute bit is set. If the 10-minute bit is set, the 10-minute bit is reset. 30 seconds are stored after clearing 0 in the memory M2.

That is, in the present invention, when pressing the emergency cooking key, the emergency cooking time is increased to 10 minutes with a time of 30 seconds set according to the time of pressing the emergency cooking key as a unit time. Repeat the operation to set the emergency cooking time to minutes.

In this way, when the emergency cooking bit is set and the user presses the clear key while the emergency cooking time is set, the clear routine is executed to clear all data such as the set emergency cooking time and then execute the display control routine and execution routine. When the start key signal is input by pressing the start key, the operation bit is set, the emergency cooking bit is reset, the error detection routine is performed to determine whether it is an error, and then the display control routine is performed to perform the emergency cooking. In the execution routine, the urgent dish is executed.

As described in detail above, the present invention does not press a number key when making an urgent dish, and sets an urgent dish time by pressing an urgent dish, thereby making it easy to operate an urgent dish by pressing a start key. The time required is short, so you can perform urgent dishes in a short time.

Claims (2)

A first step of judging the input of the key signal, and setting an emergency cooking time by counting the pressing of the emergency cooking key after setting the emergency cooking bit when the key signal input in the first step is an emergency cooking key signal; Step 2 and the third step of clearing all of the set emergency cooking time and data when the clear key signal is input with the emergency cooking bit set, and when the start key signal is input with the emergency cooking bit set.
