Abstract

본 발명은 마이컴이 전자렌지에서 키이입력의 고장유무를 체킹하는 방법에 관한 것으로, 특히 시스템에 구비된 마이컴의 빈 메모리 공간을 이용하여 입력키이의 이상유무를 체킹한 다음 그 고장 부위의 정확한 위치를 표시부를 통하여 표시함과 동시에 경보를 발하도록 함으로써 고장으로 인한 시스템의 분해시 발생되던 시간적 손실을 줄일 수 있음은 물론 그에 따른 비용도 절감되도록 된 마이컴이 구비된 전자렌지에서 키이입력의 고장유무를 체킹하는 방법에 관한 것으로서, 특정 키이신호가 입력되고 있는지를 판별하는 단계와, 상기 단계중에 특정키이 신호가 입력되고 있다고 판단되면 마이컴의 출력단을 통해 체킹신호를 체킹을 위해 설정된 키이로 출력하는 단계와 상기 단계중에 마이컴이 입력단으로 상기 체킹신호가 입력되었는지를 판단하고, 그 판단결과 입력되지 않았을 경우는 다른 키이를 순차적으로 체킹하도록 하는 단계와 상기 단계중에 체킹신호가 입력되지 않았을 경우 디지트론 표시부를 통해 그 체킹사실을 외부로 알리게 하고, 또한 부저를 통해 경보음을 발하게 하는 단계와, 상기 키이 신호를 체킹하는 단계중에 마이컴의 입력단으로 체킹신호가 입력되고 있다고 판단하면 그 체킹신호가 입력된 키이를 정확히 인식하여 디지트론 표시부로 그 고장키이를 정확히 표시하도록 함은 물론 부저를 통해 외부로 경보음을 발하도록 되는 단계로 이루어진 것을 특징으로 하는 것이다.The present invention relates to a method of checking whether there is a malfunction of a key input in a microwave oven. In particular, a microcomputer checks an abnormality of an input key using a free memory space of a microcomputer provided in the system, and then checks the exact position of the fault. Checking whether there is a key input failure in a microwave oven equipped with a microcomputer that reduces the time loss caused by disassembly of the system due to a failure by displaying an alarm and displaying an alarm at the same time. A method for determining whether a specific key signal is being input, and if it is determined that a specific key signal is input during the step, outputting a checking signal to a key set for checking through an output terminal of the microcomputer and The microcomputer determines whether the check signal is input to the input terminal during the step. If the result of the determination is not input, the step of checking the other keys sequentially, and if no checking signal is input during the step, inform the outside of the checking fact through the digitron display unit and alarm sound through the buzzer. If it is determined that the checking signal is input to the input terminal of the microcomputer during the step of checking the key signal, the key is correctly recognized and the fault key is displayed on the digitron display unit. Of course, it is characterized by consisting of steps to sound an alarm to the outside through the buzzer.

특정키이신호가 입력되고 있는지를 판별하는 단계와, 상기 단계중에 특정키이 신호가 입력되고있다고 판단되면 마이컴의 출력단을 통해 체킹신호를 체킹을 위해 설정된 키이로 출력하는 단계와, 상기 단계중에 마이컴이 입력단으로 상기 체킹신호가 입력되었는지를 판단하고, 그 판단결과 입력되지 않았을 경우는 다른 키이를 순차적으로 체킹하도록 되는 단계와, 상기 단계중에 체킹신호가 입력되지 않았을 경우 디지트론 표시부를 통해 그체킹사실을 외부로 알리게 하고, 또한 부저를 통해 경보음을 발하게 하는 단계와, 상기 키이신호를 체킹하는 단계중에 마이컴의 입력단으로 체킹신호가 입력되고 있다고 판단되면 그체킹신호가 입력된 키이를 정확히 인식하여 디지트론 표시부로 그고장키이를 정확히 표시하도록 함은 물론 부저를 통해 외부로 경보음을 발하도록 하는 되는 단계로 이루어진 것을 특징으로 하는 마이컴이 구비된 전자렌지에서 키입력의 이상유무를 체킹하는 방법.Determining whether a specific key signal is being input; if it is determined that the specific key signal is being input, outputting a checking signal to a key set for checking through an output terminal of the microcomputer; Determining whether the checking signal has been input; and if the check signal is not input, checking the other keys sequentially, and if the checking signal is not input during the step, checking the fact through the digitron display unit. If it is determined that the check signal is being input to the input terminal of the microcomputer during the step of making an alarm sound through the buzzer and checking the key signal, the digitron display unit recognizes the key inputted with the checking signal correctly. In addition to correctly displaying the key to the log, through the buzzer to the outside Checking whether there is an abnormality in the key input in the microwave oven equipped with a microcomputer characterized in that it comprises a step of making an alarm sound. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
