Abstract

본 발명은 냉장고의 냉기조절 댐퍼 오동작 검출방법에 관한 것으로서, 특히 냉기량을 조절하는 두 개의 댐퍼가 설치된 냉장고에 있어 초기전원 공급시 두 개 댐퍼의 이상유무를 판별하고, 이상 발생시 림프점등과 부저음을 송출토록 하는 냉장고의 냉기조절 댐퍼 오동작 검출방법에 관한 것이다. 하나의 리드스위치를 사용하고, 마이콤의 제어에 의해 모터를 구동하여 두 개의 댐퍼를 제어하는 냉장고의 댐퍼 제어방법에 있어서, 전원공급시 댐퍼구동용 모터를 동작시키며, 리드스위치의 오프 시점부터 신간(t)을 계수하고 리드스위치의 온/오프 횟수를 기억하는 초기구동과정(L1)과, 상기 과정 후 계수된 시간이 임의의 설정된 제1소정시간(t1)이 경과됨을 판단하여 상기 제1소정시간(t1)내에 리드스위치가 접속되지 않을 경유 하나의 특징 댐퍼가 오동작임을 인지하여 부저와 램프를 점멸하는 제1오동작 검출과정(L2)과, 상기 과정 후 계수된 시간이 임의의 설정된 제2소정시간(t2)이 되면 리드스위치의 온. 오프회수가 세팅된 소정회수와 일치하는지를 판단하여 동일할 경우 정상동작을 실행하고, 일치하지 않으면 나머지 하나의 댐퍼를 포함하는 댐퍼모터의 오동작으로 인지하여 부저와 램프를 점멸하는 제2오동작 검출과정(L3)으로 이루어진 것이다.The present invention relates to a cold air control damper malfunction detection method of the refrigerator, in particular in the refrigerator equipped with two dampers for controlling the amount of cold air to determine the presence of two dampers when the initial power supply, and when the abnormal occurrence lymph lights and buzzer sound It relates to a cold air control damper malfunction detection method of the refrigerator to be sent out. In the damper control method of a refrigerator using one reed switch and controlling a two dampers by driving a motor under the control of a microcomputer, the damper driving motor is operated when the power is supplied, The initial driving process L1 for counting t) and storing the on / off count of the reed switch, and the first predetermined time by determining that the predetermined first predetermined time t1 has elapsed since the counted time has passed. (1) A first malfunction detection process (L2) for flashing the buzzer and the lamp by recognizing that one feature damper is malfunctioning when the reed switch is not connected in (t1), and the second predetermined time at which the counted time after the process is arbitrarily set. When (t2) is reached, the reed switch is turned on. A second malfunction detection process of determining whether the off frequency coincides with the predetermined number of times and performing the normal operation if the same is the same, and if it does not match, recognizes the malfunction of the damper motor including the other damper and blinks the buzzer and the lamp ( L3).

Claims (1)

하나의 리드스위치를 사용하고, 마이콤의 제어에 의해 모터를 구동하여 두 개의 댐퍼를 제어하는 냉장고의 댐퍼 제어방법에 있어서, 전원공급시 댐퍼구동용 모터를 동작시키며, 리드스위치의 오프 시점부터 시간(t)을 계수하고, 리드스위치의 온/오프 횟수를 기억하는 초기구동과정(L1)과, 상기 과정 후 계수된 시간이 임의의 설정된 제1소정시간(t1)이 경과됨을 판단하여 상기 제1소정시간(t1)내에 리드스위치가 접속되지 않을경우 하나의 특정 댐퍼가 오동작임을 인지하여 부저와 램프를 점멸하는 제1오동작 검출과정(L2)과, 상기 과정 후 계수된 시간이 임의의 설정된 제2소정시간(t2)이 되면 리드스위치의 온. 오프회수와 세팅된 소정회수를 비교하여 동일할 경우 정상 동작을 실행하고, 일치하지 않으면 나머지 하나의 댐퍼를 포함하는 댐퍼모터의 오동작으로 인지하여 부저와 램프를 점멸하는 제2오동작 검출과정(L3)으로 이루어진 것을 특징으로 하는 냉장고의 냉기조절 댐퍼 오동작 검출방법.In a damper control method of a refrigerator in which a single reed switch is used and a motor is controlled by a microcomputer to control two dampers, the damper driving motor is operated when the power is supplied, The first driving process L1 counting t) and storing the on / off count of the reed switch, and the first predetermined time t1 after determining that the predetermined counting time t1 has elapsed after the process is determined, have elapsed. The first malfunction detection process L2 which blinks the buzzer and the lamp by recognizing that one specific damper is malfunctioning when the reed switch is not connected within the time t1, and the second predetermined predetermined time after which the counted time is randomly set. When the time t2 is reached, the reed switch is turned on. The second malfunction detection process (L3) which compares the off frequency and the predetermined number of times and performs the normal operation if the same is the same, and if it does not match, recognizes the malfunction of the damper motor including the other damper and blinks the buzzer and the lamp. Cold air control damper malfunction detection method characterized in that consisting of. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
