Abstract

본 발명은 냉장고의 통상운전모드와 지그모드를 판별하여 수행하기 위하여 냉장고에 구비된 마이크로컴퓨터(1), 다수개 입출력단자를 구비하는 모드제어용IC(2), 통상모드용PCB기판(3) 및 지그모드에서 냉장고에 접속될 수 있는 PCB기판(4)로 이루어지는 하드웨어구성을 갖는 냉장고의 지그모드 판별회로이다.The present invention provides a microcomputer (1) provided in the refrigerator, a mode control IC (2) including a plurality of input / output terminals, a normal mode PCB board (3), and the like to determine and perform the normal operation mode and the jig mode of the refrigerator. It is a jig mode determination circuit of a refrigerator having a hardware configuration consisting of a PCB board 4 which can be connected to the refrigerator in the jig mode.

이에 따라 냉장고 시스템관리자가 냉장고 시스템관리자가 지그모드PCB기판을 접속시키면 자동적으로 지그모드가 수행가능해진다.Accordingly, when the refrigerator system manager connects the jig mode PCB board, the jig mode can be automatically performed.

Claims (1)

냉장고에 구비된 마이크로컴퓨터(1); 통상모드용 PCB기판(3); 지그모드에서 냉장고회로에 접속될 수 있는 지그모드용PCB기판(4); 상기 통상모드용PCB기판(3) 및 지그모드용PCB기판(4)의 4개 출력신호상태를 상기 마이크로컴퓨터(1)에 4개의 입력신호로서 적합하게 입력시키기 위한 다수개 입출력단자를 구비한 모드제어용IC(2)를 포함하는 냉장고 지그모드 판별회로에 있어서, 상기 마이크로컴퓨터(1)가 제1입력과 제2입력의 상태를 감지하는 단계와, 상기 감지된 제1이력과 제2입력이 동시에 "온"상태인지 판단하는 단계와, 상기 판단단계에서 제1입력과 제2입력이 동시에 "온"상태이면 소정시간이 경과하였는지 판단하는 단계와, 상기 소정시간 간격동안 지속적으로 제1입력과 제2입력이 동시에 "온"상태로 일치하면 지그모드를 수행하는 단계로 지그모드들 판별하는 것을 특징으로 하는 냉장고 지그모드 판별회로.A microcomputer 1 provided in the refrigerator; PCB board for normal mode (3); A PCB board for jig mode 4 which can be connected to the refrigerator circuit in the jig mode; A mode having a plurality of input / output terminals for suitably inputting four output signal states of the normal mode PCB board 3 and the jig mode PCB board 4 as four input signals to the microcomputer 1. In the refrigerator jig mode determination circuit including a control IC (2), the microcomputer (1) detects the state of the first input and the second input, the sensed first history and the second input at the same time Determining whether the state is in the "ON" state, determining whether a predetermined time has elapsed when the first input and the second input are in the "ON" state at the same time, and continuously performing the first input and the second time during the predetermined time interval. The jig mode discrimination circuit characterized in that the jig modes are determined by performing the jig mode when the two inputs coincide with the "on" state at the same time. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
