The present invention relates to a cooking completion notification control method for a microwave oven, and more particularly, to a cooking completion notification control method for a microwave oven to repeatedly notify that cooking is completed at a predetermined time interval when the door is not opened after cooking completion.

In a microwave oven having a conventional electronic control circuit, cooking is performed by heating food by heating means such as a magnetron and a heater. When cooking is completed, a buzzer is generated for a predetermined time (for example, 10 seconds) to indicate that cooking is completed. It was supposed to be announced.

That is, the cooking completion notification method of the conventional microwave oven only buzzes for a predetermined time when cooking is completed, and does not perform any operation thereafter.

However, when the cooking is completed, the buzzer sounds for one time only to notify the completion of cooking, and since no notification operation is performed thereafter, if the user does not hear the cooking completion buzzer at the completion of cooking, the microwave lamp is turned on. Make sure it's off before you know it's ready.

For example, if you put food in a microwave oven in the kitchen, start cooking, watch TV in the room, or wait for the completion of cooking while doing something else, if you do not hear the cooking buzzer, the cooking is completed after the cooking is completed. There is an irrational issue waiting to become.

In addition, even after listening to the cooked buzzer, you may delay putting out the food for a while or watching the TV. For this reason, the cooked food is left in the microwave for a long time. Problems such as not eating or eating food on time.

The present invention is to provide a cooking completion notification control method of the microwave oven to notify by blinking the buzzer sound and high light periodically until the completion of cooking to remove the food after the completion of the conventional problem.

An object of the present invention as described above comprises the steps of checking whether the door is opened after cooking is completed, if the door is opened, ending the cooking completion notification operation, if the door is not opened, counting the alarm cycle time, and Determining whether the counted alarm cycle time is equal to the preset set time; when the alarm cycle time reaches the preset time, the alarm cycle time counter is initialized, a buzzer sounds for a predetermined time, and the lamp is turned on. This is accomplished by programming a program on MyOn that is configured to perform steps to return to the door open check step while repeating on / off cooking completion.

Hereinafter, an embodiment of a cooking completion notification control method for a microwave oven according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a cooking completion notification control block of the microwave oven according to the present invention, Figure 2 is a cooking completion notification control flow chart of the microwave oven according to the present invention, as shown in the function selection and start, cancel key, etc. from the keyboard A key input unit 1 for receiving various key signals, a sensor unit 2 for detecting weight, temperature or humidity, and an operation state of each unit from a sensor installed according to a set type to control cooking, and a door A door detecting unit 3 for detecting an open / closed state, a memory 4 storing automatic cooking data such as each cooking name and heating time, an automatic cooking program and a cooking completion notification program, and the like; According to the key signal through the key input unit 1, the detection signal of the sensor unit 2 and the door detection signal of the door detection unit 3 based on the automatic cooking program of the memory 4 of the memory 4 Auto Cooking The microcomputer 5 which reads the information and automatically controls the cooking and controls the cooking completion notification according to the present invention, and a display unit which displays the operating state of the microwave oven and the cooking time thereof under the control of the microcomputer 5. (6) and a load driver 7 for driving the magnetron, the heater, the cooling fan, and various loads necessary for cooking and the interior lamp 8 and the buzzer 9 under the control of the microcomputer 5, respectively. do.

In addition, the automatic cooking completion notification control method according to the present invention, which is controlled by the microcomputer 5, determines whether cooking is started as shown in the control flowchart of FIG. Determining whether the cooking is complete; checking whether the door is opened when cooking is completed; and if the door is opened once after cooking is finished, the cooking completion notification operation is finished, and the door is never opened after cooking. Otherwise, counting the alarm cycle time; determining whether the counted alarm cycle time is equal to a preset set time while counting the alarm cycle time; and if the alarm cycle time is less than the set time, the door. When the alarm cycle time reaches the set time, the alarm cycle time counter is reset. And while generating a buzzer sound for a predetermined time and repeats the interior light on / off to notify the completion of cooking while performing the alarm step to return to the door open check step.

Here, if the door has not been opened once after the completion of the cooking door check, it is determined whether there is a cancel key input, and if there is a cancel key input, the notification control ends, and if there is no cancel key input, the alarm cycle count is started. You can also program including steps.

The alarm step may include: counting one alarm time after initializing the alarm cycle time counter when the alarm cycle time reaches the set time; and predetermined time for which the one alarm time count time is preset. (E.g., 10 seconds), and if the one-time alarm time is less than the predetermined time, the buzzer sound is generated and the interior light is repeatedly turned on and off to inform the completion of cooking. If there is no door open and there is no cancel key input while checking whether there is an input, repeating the step after the one alarm time count step, and if the one alarm time reaches a predetermined time, the one alarm time counter After initializing the off and the buzzer and the interior light off, the door opening check step is performed.

The cooking completion notification control method of the microwave oven made as described above is as follows.

When the cooking is started and the cooking is in progress, the microcomputer 5 reads the cooking name previously stored in the memory 4 and the heating time or humidity, temperature value, and the like, and cooks according to each detection signal detected by the sensor unit 2. You control the completion.

In this way, when cooking is completed by performing cooking, a program for repeatedly informing that cooking is completed according to the present invention is performed.

First, when the cooking is completed by determining whether cooking is completed, a step of determining whether the door is opened through the door detecting unit 3 is performed. This is to determine that when the door is opened after the completion of cooking, the user recognizes the completion of cooking, and after the completion of cooking, when the door is not opened, the user does not recognize the completion of cooking.

If it is determined that the door is open after the completion of cooking, the door is not opened at all, and if there is no cancel key input, if there is no cancel key input, the alarm cycle time is counted. .

Subsequently, the alarm cycle time is counted, and a determination is made as to whether the counted alarm cycle time is equal to a preset set time (for example, 5 to 10 minutes).

As a result of comparing the alarm cycle time with the set time, if the counted alarm cycle time is less than the set time, the process returns to the door open check step, and if the counted alarm cycle time reaches the set time, After initializing the alarm cycle time counter and counting one alarm time, it is determined whether the one alarm time count time is a predetermined time set in advance (eg, 10 seconds), and if the one notification time is less than the predetermined time set. In addition to generating a buzzer sound and repeating the on / off of the interior lamp to indicate completion of cooking, and checking whether there is a door open and a cancel key input, if there is no door open and there is no cancel key input, the alarm time counter is initialized once. After turning off the buzzer and the lamp, go back to the door open check step and wait until the next alarm cycle time. You will be

That is, if the door does not open after the completion of cooking and there is no cancel key input, the buzzer sounds for a predetermined time (for example, 10 seconds) at a predetermined time period (for example, 5 to 10 minutes), and the lamp is flashed to indicate that cooking is completed. You will be notified.

And, if the door is opened at least once after the completion of cooking, it is determined that the food is taken out by recognizing that the cooking is completed, the notification control to notify the completion of cooking is no longer performed.

In addition, when the door is not opened, but there is a cancel key input, the alarm is terminated, to prevent unnecessary alarm when waiting for the user without waiting to immediately take out the food in the microwave after recognizing the completion of cooking.

As described in detail above, according to the present invention, if the door is not opened once or the cancel key is not pressed after the completion of cooking in the microwave, it is notified that the cooking is completed by the buzzer sound and the high internal point by a predetermined time period at a predetermined time period, so that the cooking is completed. There is an effect that can be announced.
