Abstract
본 발명은 냉장고에 채용된 소냉장실의 개폐를 자동으로 제어하는 기술에 관한 것으로, 특히 물체를 감지하는 포토인터럽트센서와 도어개폐를 감지하는 스위치에 의한 신호를 입력받은 마이컴에서 트래이를 구동시키는 구동모터를 자동으로 정, 역회전시켜 사용자의 직접적인 조작없이도 용이하게 개폐가 가능한 소(小)냉장실의 개폐 제어방법에 관한 것으로서, 포토인터럽트부에서 물체를 감지하면(S10) 트래이를 이동시키는 구동모터를 동작시켜(S11) 정방향으로 이동제어하되, 도어스위치1이 온될때까지 계속하여 구동제어하며(S12)(S13), 포토인터럽트부에서 물체를 감지하지 못하면 트래이를 이동시키는 구동모터를 동작시켜(S14)역방향으로 이동제어하되, 도어스위치2가 온될때까지 계속하여 구동제어하도록(S15)(S16)실행된 특징이 있다.The present invention relates to a technology for automatically controlling the opening and closing of the small refrigerator compartment employed in the refrigerator, in particular a drive motor for driving the tray in the microcomputer received a signal by the photo interrupt sensor for detecting the object and the switch for detecting the opening and closing of the door The present invention relates to a method for controlling the opening and closing of a small refrigerating chamber, which can be easily opened and closed without the user's direct manipulation by automatically rotating the motor forward and backward. (S11) movement control in the forward direction, but continues to drive control until the door switch 1 is turned on (S12) (S13), if the object is not detected in the photo interruption unit (S14) by operating the drive motor to move the tray (S14) The movement is controlled in the reverse direction, but continues to drive control until the door switch 2 is turned on (S15).
