Abstract

본 발명은 전자레인지의 요리시간 자동지움장치 및 그 방법에 관한 것으로, 종래에는 사용자가 요리시간이 남아있는 상태에서 요리가 완료되었다고 판단하여 요리를 꺼내고 닫게되면 남아있는 요리시간은 사용자에 의해 클리어되지 않는 한 정지상태로 그대로 방치된다. 이와같은 상태에서 판단력없는 어린아이들의 장난에 의해 자동요리시작키이가 눌러서 무부하상태에서 요리가 진행되면 전자레인지에 무리가 가게되고 심한 경우엔 파괴되는 경우도 발생하게 되었다.The present invention relates to an automatic erasing device for a cooking time of a microwave oven and a method thereof. In the related art, when a user determines that cooking is completed in a state in which a cooking time remains, the cooking time remaining is not cleared by the user. Unless otherwise left unattended. In this state, when the automatic cooking start key is pressed and the cooking proceeds under no load by the mischief of the juvenile children, the microwaves are crowded and, in severe cases, they are destroyed.

따라서 종래의 결함을 감안하여 본 발명은 남아있는 요리데이타에 관계없이 일정시간이 지나면 마이크로프로세서에서 이를 감지하여 자동적으로 요리데이타를 클리어시키도록 하여 전자레인지를 위험으로부터 벗어나도록 하였다.Therefore, in view of the conventional defect, the present invention is to detect the microprocessor after a certain time regardless of the remaining cooking data to automatically clear the cooking data so that the microwave oven from the danger.

Claims

The cooking progress setting key input from the hunger input unit 1, the key input discrimination unit (2) for discriminating the presence or absence, and the power supply and oscillation frequency applied from the power supply unit (3) and the power generation unit (4) A microprocessor 5 for controlling each necessary system operation, a time counting unit 6 for counting the cooking time input from the key input unit 1, and a door opening / closing detection for detecting opening and closing of the microwave oven door during cooking. And the automatic cooking time clearing unit 8 for automatically clearing the remaining cooking time when the cooking stop time output from the time counting unit 6 lasts for a predetermined time. Automatic erasing device for cooking time of the electronic range, characterized in that consisting of a display (9).

If there is no start key detected by checking the cooking start key, check the door flag and 1 second flag set and if it is not set, check the key again or not.If the cooking start key is detected, set the cooking auxiliary flag and open the door. If opening and closing of the door is detected, the main and power relays are turned off to stop cooking, and if the door is closed again, if the door is closed, the stop time is checked by performing clock up. A method for automatically erasing the cooking time of a microwave oven, characterized in that the remaining cooking data is cleared after a predetermined time elapses.
