Abstract
본 발명은 가변팽창밸브를 구비한 냉장고에 관한 것으로, 증발기(4) 입구부에 소유량포트(12) 및 대유량포트(11)를 갖고 있는 볼밸브(10)와, 상기 볼밸브(10)를 회동시키는 서보모터(20)와, 상기 서보모터(20)를 제어하는 마이콤(30)과, 증발기(4) 출구에 위치하여 냉매의 상태를 감지하여 상기 마이콤(30)에 신호를 보내는 온도감지부(40)로 구성하여, 온도감지부(40)의 신호를 받은 마이콤(30)의 제어에 의해 볼밸브(10)를 회동시켜서 소유량포트(12)를 사용하여 맹매의 유량을 감소시키며, 반대로 냉매량이 부족하여 증발기(4) 출구에서 과열이 생기는 경우 또는 급속히 냉장고의 온도를 낮추고저 할 때는 마이콤(30)의 제어에 의해 볼밸브(10)를 회동시켜 대유량포트(11)를 사용하여 냉매의 유량을 증가시켜서 냉장고의 온도를 낮출 수 있다.The present invention relates to a refrigerator having a variable expansion valve, comprising a ball valve (10) having a low flow rate port (12) and a large flow rate port (11) at the inlet of the evaporator (4), and the ball valve (10). The servo motor 20 to rotate, the microcomputer 30 for controlling the servo motor 20, and the temperature sensing unit which is located at the outlet of the evaporator 4 to detect the state of the refrigerant and sends a signal to the microcomputer 30 The ball valve 10 is rotated by the control of the microcomputer 30 which receives the signal of the temperature sensing unit 40, and the flow rate of the hawk is reduced by using the low flow rate port 12. In the case where there is a lack of overheating at the outlet of the evaporator 4 or when the temperature of the refrigerator is rapidly lowered, the ball valve 10 is rotated by the control of the microcomputer 30 and the large flow rate port 11 is used to cool the refrigerant. The temperature of the refrigerator can be lowered by increasing the flow rate.
