이와같은 목적을 달성하기 위한 본 발명은, 냉동실로 냉기를 강제유입시키는 냉각팬을 구비한 냉장고의 냉각팬 제어방법에 있어서, 압축기가 온타임일때 제1소정시간동안 냉각팬의 구동을 중지시키는 과정과, 압축기가 온타임이고 상기 제1소정시간이 경과하면 제2소정시간동안 냉각팬을 구동시키는 과정과, 압축기가 온타임일때 상기 제2소정시간이 경과하면 다시 제1소정시간동안 냉각팬을 구동시키는 제어를 반복하는 과정과, 압축기가 오프타임이면 냉각팬의 구동을 중지시키는 과정을 구비하여 된 것이다.In order to achieve the above object, the present invention relates to a cooling fan control method of a refrigerator having a cooling fan for introducing cold air into a freezer compartment, the process of stopping the operation of the cooling fan for a first predetermined time when the compressor is on time. And driving the cooling fan for a second predetermined time when the compressor is on time and the first predetermined time has elapsed, and when the second predetermined time has elapsed when the compressor is on time, restarting the cooling fan for the first predetermined time.

이하, 첨부된 도면에 의거하여 본 발명을 보다 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 발명이 적용되는 냉장고(10)의 냉동실(11) 구성도를 나타낸 것으로, 미도시된 압축기가 온되면, 냉각기(12)는 냉각되어 열교환을 일으키고, 이때 발생되는 냉기는 모터(13)의 구동으로 회전되는 냉각팬(14)을 통해서 냉동실(11)로 투입된다. 미설명부호 16은 냉동실 도어이다.1 is a view illustrating a configuration of a freezer compartment 11 of a refrigerator 10 to which the present invention is applied. When a compressor (not shown) is turned on, the cooler 12 cools to cause heat exchange. It is fed into the freezing chamber 11 through the cooling fan 14 that is rotated by the drive. Reference numeral 16 is a freezer door.
제3도는 본 발명이 적용되는 냉장고의 회로도를 나타낸 것으로, 본 발명에 따른 일정 프로그램을 내장한 원 칩 마이컴(20)의 입력포트(P1)에는 냉동실 온도감지소자(15), 저항(R1)(R2)으로 구성된 냉동실 온도감지부(30)가 접속되어 냉동실(11) 온도를 감지함으로써 냉동실(11)의 온도를 제어할수 있게 한다.3 is a circuit diagram of a refrigerator to which the present invention is applied. The input port P1 of the one-chip microcomputer 20 having a predetermined program according to the present invention has a freezer compartment temperature sensing element 15 and a resistor R1 ( The freezer compartment temperature detecting unit 30 configured as R2) is connected to control the temperature of the freezer compartment 11 by sensing the freezer compartment 11 temperature.
또한, 마이컴(20)의 출력포트(P2)에는 인버터(I1), 다이오드(D1), 릴레이(RY1) 및 압축기(CP)로 이루어진 압축기 구동부(40)가 접속되어 압축기(CP)를 구동시키게 되는데, 압축기(CP) 구동을 위하여 마이컴(20)이 하이레벨 신호를 출력하면, 이 출력된 신호는 인버터(I1)를 통해 반전되고 동시에 릴레이(RY1)가 통전됨으로써 압축기(CP)는 구동하는 것이다.In addition, the compressor port 40 including the inverter I1, the diode D1, the relay RY1, and the compressor CP is connected to the output port P2 of the microcomputer 20 to drive the compressor CP. When the microcomputer 20 outputs a high level signal for driving the compressor CP, the output signal is inverted through the inverter I1 and at the same time, the relay RY1 is energized so that the compressor CP is driven.
또한, 마이컴(20)의 출력포트(P2)에는 인버터(I2), 다이오드(D2), 릴레이(RY2) 및 팬모터(13)로 이루어진 냉각팬 구동부(50)가 접속되어 냉각팬(14)를 구동시키게 되는데, 팬모터(13) 구동을 위하여 마이컴(20)이 하이레벨 신호를 출력하면, 이 출력된 신호는 인버터(I2)를 통해 반전되고 동시에 릴레이(RY2)가 통전됨으로써 팬모터(13)는 구동하고 냉각팬(14)은 회전하게 된다.In addition, a cooling fan driving unit 50 including an inverter I2, a diode D2, a relay RY2, and a fan motor 13 is connected to the output port P2 of the microcomputer 20 to connect the cooling fan 14. When the microcomputer 20 outputs a high level signal for driving the fan motor 13, the output signal is inverted through the inverter I2 and at the same time, the relay RY2 is energized so that the fan motor 13 is energized. Is driven and the cooling fan 14 is rotated.
또한, 본 발명에 따르자면, 압축기(CP)의 온시에 냉각팬(14)의 구동을 간헐적으로 구동시키게 되는바, 냉각팬(14)이 정지하고 있는 동안에는 냉각기(12)의 온도는 상대적으로 낮아진다. 그 이유는 냉각팬(14)의 정지로 냉기의 냉동실(11)유입이 차단됨으로써 냉각기(11)의 냉기형성이 더욱 증가한다. 이때에 다시 냉각팬(14)을 구동시키면 더욱 차가워진 냉기가 냉동실(11)로 투입된다.According to the present invention, the driving of the cooling fan 14 is intermittently driven when the compressor CP is turned on, and thus the temperature of the cooler 12 is relatively lowered while the cooling fan 14 is stopped. . The reason for this is that the inlet of the freezing chamber 11 of the cold air is blocked by the stop of the cooling fan 14, and thus the cold air formation of the cooler 11 is further increased. At this time, if the cooling fan 14 is driven again, colder cold air is introduced into the freezing chamber 11.
따라서, 냉동실(11)의 온도곡선은 제2도의 곡선(L1)과 같이 된다.Therefore, the temperature curve of the freezer compartment 11 becomes like the curve L1 of FIG.
이하, 제4도의 흐름도를 참조하여 본 발명의 작용효과를 이하 설명한다.Hereinafter, the operation and effect of the present invention will be described with reference to the flowchart of FIG.
먼저, 전원이 인가되면 마이컴(20)은 사용자가 설정한 온도에 준하여 설정되는압축기(CP)의 온타임(ON-TIME)이 도래되었는가를 판단한다(S1단계). 여기서 압축기(CP)의 온타임이 아니면 포트(P2)(P3)로의 출력을 차단하여 압축기(CP)를 오프시키고(S7단계), 냉각팬(13)을 오프시킨다(S8단계).First, when power is applied, the microcomputer 20 determines whether the on-time of the compressor CP set according to the temperature set by the user has arrived (step S1). If the compressor CP is not on time, the output to the ports P2 and P3 is cut off to turn off the compressor CP (step S7), and the cooling fan 13 is turned off (step S8).
그러나, 상기 S1단계에서 압축기(CP)가 온타임일때에는 포트(P2)로 하이레벨 신호를 출력하여 압축기(CP)를 구동시키고(S2단계), 포트(P3)로의 출력을 차단하여 냉각팬(13)을 오프시킨다(S3단계). 이때 부터 시간을 계수하여 제1소정시간(예: 1분 30초)이 경과하는지를 판단한다(S4단계). 이때에 냉각기(12)에는 보다 차거운 냉기가 형성된다.However, in the step S1, when the compressor CP is on time, the compressor CP is driven by outputting a high level signal to the port P2 (step S2), and the output to the port P3 is blocked so that the cooling fan ( 13) is turned off (step S3). From this time, the time is counted to determine whether the first predetermined time (for example, 1 minute 30 seconds) has elapsed (step S4). At this time, cooler cold air is formed in the cooler 12.
상기 S4단계에서 제1소정시간이 경과하면, 다시 포트(P3)로 하이레벨신호를 출력하여 냉각팬(13)을 온시킨다(S5단계). 따라서, 냉각기(12)의 냉기는 냉동실(11)로 투입된다. 또한, 상기 냉각팬(13)이 온된 시점에서 다시 시간을 계수하여 제2소정시간(예: 3분 30초)의 경과를 판단한다(S6단계).When the first predetermined time elapses in step S4, the cooling fan 13 is turned on by outputting a high level signal to the port P3 again (step S5). Therefore, the cold air of the cooler 12 is injected into the freezer compartment 11. In addition, when the cooling fan 13 is turned on, time is counted again to determine the progress of the second predetermined time (eg, 3 minutes and 30 seconds) (step S6).
상기 S6단계에서 제2소정시간이 경과되면, 냉각팬(13)을 오프시킨다.When the second predetermined time passes in step S6, the cooling fan 13 is turned off.
따라서, 냉각기(12)에는 차가운 냉기가 형성되는 것이다.Therefore, cool cold air is formed in the cooler 12.
이상에서와 같이 본 발명은 압축기의 온타임시 냉각팬을 간헐적으로 구동시킴으로써 소비전력을 절감할 수 있고, 상기 냉각팬의 간헐적인 동작에 따라 냉각효율을 더 상승시킨 유용한 발명이다.As described above, the present invention can reduce power consumption by intermittently driving a cooling fan during on-time of a compressor, and is a useful invention that further increases cooling efficiency according to the intermittent operation of the cooling fan.
