The present invention is a microwave oven, in particular a microwave oven employing a microcomputer as a controller (controller), a microwave oven that can be easily cooked by dividing various dishes such as rice, stew, stew, steamed according to the cooking amount It relates to a cooking control method of.

The conventional microwave oven is mainly controlled by the time (TIMB), the microwave oven of the time control method such as the user directly select the appropriate cooking time and output according to the type and amount of food to be cooked, such as stew or steaming This is difficult and cumbersome. Particularly, when cooking in a microwave oven, it is necessary to change the output of the microwave during cooking, so it is necessary to take steam. Therefore, each user inputs the cooking time and output for each cooking step while requiring careful attention of the user. It is inconvenient to press the pad repeatedly several times, and foods such as stew and steaming are seasoned or turned over during cooking to improve the taste. It is difficult to remember.

The purpose of the present invention is to solve the above disadvantages, and in addition to the functions of the general microwave oven, the types of food are classified into menus such as rice, stew, stewed foods, and steamed foods. In order to provide a cooking control method for a microwave oven in which the standard cooking time and the output change during cooking and the output level are set automatically according to the amount of food input, the cooking is performed. The method and effects of the present invention are described in more detail.

FIG. 1 shows a hardware configuration of a microwave oven to which the method of the present invention is applied. When each pad signal from the pad unit 6 is input to the microcomputer 1, the microcomputer 1 displays the input contents. As shown in (3), the magnetron is operated by driving the relay control unit 2 according to the program execution, thereby controlling the output and cooking time of the microwave oven. At this time, the microcomputer 1 drives the buzzer 5 when the acceptable pad is pressed, when cooking is finished, and when the microwave oven is malfunctioning, to sound an alarm.

2 shows an algorithm performed by the microcomputer 1 according to the present invention. First, when the power is input, the program comes to the start position and the microcomputer 1 prevents the initial abnormal state of the microcomputer 1. The internal RAM and each input / output port are made in the desired state.

In this state, it is determined whether cooking is being performed, and if it is not cooking, it waits for pad input. If cooking, the cooking time is reduced while counting down the cooking time and adding the seasoning of cooked food such as stew (or steaming). Determine if it's time to turn over (or turn over food). In this case, when the seasoning time is stopped, the cooking is stopped and a sounding alarm is issued.When the seasoning time is over or past, it is determined whether to end the cooking again. ) To finish cooking.

This is the first function execution step.

On the other hand, when the cooking is not finished, it is determined whether the pad input is performed, and the input of the cooking cancel pad is first determined, and in the case of the cancel pad input, the cancel pad input goes to the start position and performs the function of the first step. It is the highest priority for all pad inputs.

If it is not the cancellation pad, it is determined whether the cooking pad input of rice, stew, stew or steaming is input. In the case of such a cooking pad input, it is again determined whether the cooking is performed or not. In this case, the serving portion is displayed for a predetermined time through the display unit 3 and an alarm sound is generated. Therefore, the cooking pad is operated not to operate as a pad for cooking but to check the current cooking input state. .

In this case, when not cooking, the cooking code is stored and an alarm sounds for a predetermined time, after which the function of a general microwave oven is performed.

This is the second functional step.

On the other hand, if the pad input in step 2 is not a cooking pad for rice, stew, stew, or steamed, it is determined whether it is being cooked, and if it is cooking, it goes to the loop and ignores it even if the rest of the pad is pressed to prevent malfunction. When not cooking, it is determined whether the cooking amount pad (hereinafter, referred to as a serving pad) is input. At this time, if the cooking pad is input, it is determined whether the cooking code is input again, and if the cooking code is not input, the user goes to the loop and ignores the input pad. If the cooking code is input, the serving code is stored and the predetermined time is stored. Will sound an alarm. On the other hand, if the serving pad is not input, it is determined whether the cooking start pad is input again, and when the cooking start pad is not input, it goes to the loop. In the case of the cooking start pad input, it is determined whether the door is opened and the door is opened. Go to to ignore the input of the cooking pad, and if the door is closed, it is judged whether the cooking and serving code is stored again, and if it is stored, it goes through a lot of cooking experiments for each cooked food such as rice, stew, stew or steaming. The standard cooking time, the time required for a certain output change during cooking, and the output level are automatically sorted according to the input cooking type and serving, and stored in the memory. There is no need to adjust the output.

On the other hand, in the case of no input of cooking and serving code, it goes to the loop and ignores the input of the "cooking start" pad.

3 shows cooking data automatically set according to the cooking control method of the present invention. When rice (or grain rice) is cooked, its output state is divided into three stages according to cooking time. In the first stage, the maximum output (100%) is maintained for a predetermined time according to each serving, so the rice is boiled and the water is reduced to some extent. do. Therefore, like rice cooked with a general electric rice cooker will maintain a chewy and light taste. Here, the third step represents a time in which only the cooking time is counted down without high frequency heating.

In addition, in the case of doenjang stew, fish stew, or chicken steaming, the cooking process is divided into two stages, and a time period between putting the seasoning or inverting the cooked food is set between the first and second stages. The subtraction function is not achieved, and when the seasoning time arrives as described above, the cooking is stopped as described above and a wave warning sound is issued.

This is the third function execution step.

As a result, when the correct cooking type and serving are inputted, the cooking time and output of the cooking type and serving are automatically selected. Therefore, the number of pad inputs for cooking can be limited to three times or less. However, the cooking control method of the present invention can be applied to the electric rice cooker of the built-in microcomputer.

As described above, according to the cooking control method of the present invention, the cooking time according to the cooking type and amount is automatically adjusted and processed according to the cooking type and the cooking level (serving) such as rice, stew, stew and steaming. And it is not necessary to select the output, and cooking is done by 3 or less pad inputs such as cooking pad, cooking amount (serving) pad, and cooking start pad for cooking type. There are also benefits that can be improved.

Claims (3)

In a microwave oven that employs a microcomputer as a controller, a cooking pad for rice, stew, stew, and steaming is provided to wait for pad input depending on whether it is currently being cooked or to reduce seasoning time while cooking time is added. 1st step to stop cooking time by stopping the cooking time by clearing the code during cooking and emitting a beeping sound when cooking is finished and sounding several times when cooking is finished, inputting each cooking pad of rice, stew, stew or steaming In the case of cooking pad input, if the cooking time is being input, the current cooking amount is displayed for a predetermined time, and if not, the cooking code is stored for a predetermined time, and then a warning sound is generated for a predetermined time, and the second step of performing a general function is performed.
