Abstract

본 발명은 세트를 동작하기전 히터 및 주요 구동부 등의 이상유무를 자체 진단하여 이를 외부로 표시하여 주는 온풍·선풍기의 자체이상유무 진단방법에 관한 것이다.본 발명은 자체진단키가 입력되면 송풍팬 및 히터를 구동하고,타이머를 온하는 제1과정;소정시간이 경과되면 타이머를 오프하고 히터의 온도가 임의의 설정온도에 도달하였는가를 판별하는 제2과정;상기 제2과정에서 히터의 온도가 임의의 온도와 일치하면 히터 및 송풍팬을 정지하고 정상상태임을 표시하는 제3과정;상기 제2과정에서 히터가 온도가 임의의 온도와 일치하지 않으면,마이컴의 각 포트의 전압값을 체크하는 제4과정;상기 제4과정에서 마이컴의 각 포트의 값이 이미 저장된 값과 일치하지 않으면 부위별로 에러메세지를 표시하는 제5과정을 구비하여 된 것이다.따라서 본 발명은 온풍·선풍기의 자체 이상유무를 각 부위별로 정확하게 확인할 수 있게 되어,이를 토대로 신속한 에프터서비스를 받을 수 있는 등 결과적으로 제품의 신뢰도를 높힌 유용한 발명이다.The present invention relates to a method for diagnosing whether there is an abnormality of a hot air fan or a fan that self-diagnoses an abnormality such as a heater and a main drive unit before operating the set and displays it externally. And a first process of driving the heater and turning on the timer; a second process of turning off the timer and determining whether the temperature of the heater reaches a predetermined set temperature after a predetermined time has elapsed; A third step of stopping the heater and the blower fan when the temperature matches the predetermined temperature and indicating a normal state; a second step of checking the voltage value of each port of the microcomputer if the temperature does not match the predetermined temperature in the second process Step 4; In the fourth step, if the value of each port of the microcomputer does not match the already stored value, a fifth step of displaying an error message for each part is provided. It said hot air, is able to determine accurately its own abnormality of fans of each region, and to receive a speedy after-service basis as a result it is a useful invention nophin the reliability of the product.

Description

온풍·선풍기의 자체 이상유무 진단방법Method of diagnosing abnormality of hot air fan

Claims (2)

자체진단키가 입력되면 송풍팬 및 히터를 구동하고,타이머를 온하는 제1과정;소정시간이 경과되면 타이머를 오프하고 히터의 온도가 임의의 설정온도에 도달하였는가를 판별하는 제2과정;상기 제2과정에서 히터의 온도가 임의의 온도와 일치하면 히터 및 송풍팬을 정지하고 정상상태임을 표시하는 제3과정;상기 제2과정에서 히터가 온도가 임의의 온도와 일치하지 않으면,마이컴의 각 포트의 전압값을 체크하는 제4과정;및 상기 제4과정에서 마이컴의 각 포트의 값이 이미 저장된 값과 일치하지 않으면 부위별로 에러메세지를 표시하는 제5과정을 구비하여 된 것을 특징으로 하는 온풍·선풍기의 자체 이상유무 진단방법.A first process of driving the blower fan and the heater when the self-diagnosis key is input, turning on the timer; a second process of turning off the timer and determining whether the temperature of the heater reaches a predetermined set temperature when a predetermined time elapses; A third process of stopping the heater and the blower fan and displaying a normal state when the temperature of the heater matches the predetermined temperature in the second process; if the temperature of the heater does not match the arbitrary temperature in the second process, A fourth step of checking a voltage value of the port; and a fifth step of displaying an error message for each part if a value of each port of the microcomputer does not match a stored value in the fourth step; · Diagnosis method of fan's own abnormality. 제1항에 있어서,상기 제5과정에서 3개의 표트 전압이 OV로 검출되면 히터가 불량한 것으로 판별하여 그에 따른 에러 메시지를 출력하는 것을 특징으로 하는 온풍·선풍기의 자체 이상유무 진단방법.The method of claim 1, wherein when the three VOT voltages are detected as OV in the fifth process, the heater is determined to be inferior and an error message is output accordingly. ※ 참고사항: 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the original application.
