상기와 같은 구성에 적용되는 본 발명에 작용 및 효과를 제2도의 제어흐름도를 참조하여 설명한다.The operation and effect of the present invention applied to the above configuration will be described with reference to the control flow diagram of FIG.

먼저, 전원을 인가한 후, 냉장고의 통상의 제어를 수행함에 있어, 포트(P3)로 출력되는 신호(low signal)의 누적시간을 계산하여 압축기(CP)가 운전한지 소정시간(예: 8시간)이 경과함을 검출하여 제상시기를 판단한다(S1단계). 여기서 제상시기가 검출되지 아니하면 통상의 운전제어를 수해한다(S2단계).First, after the power is applied, in performing normal control of the refrigerator, a cumulative time of a low signal output to the port P3 is calculated and a predetermined time (eg, 8 hours) when the compressor CP is operated. ) Is determined to determine the defrost time (step S1). If the defrosting time is not detected here, normal operation control is performed (step S2).

그러나, 상기 S1단계에서 제상시기가 검출되면 포트(P5)로 로우신호를 출력하여 제상히터(HTR)를 발열시킨다(S3단계).However, when the defrosting time is detected in the step S1, the low signal is output to the port P5 to generate the defrost heater HTR (step S3).

그리고, 포트(P2)로 입력되는 냉각기의 온도를 검출하여 제상완료를 검출한다(S4단계). 여기서, 제상완료시점이 검출되면, 시간카운트를 개시하며(S5단계), 동시에 제상히터(HTR)의 구동을 중지시키고, 소정의 시간(예: 7분)동안 포트(P6)로 로우신호를 출력하여 압축기 냉각용 팬모터(CM)를 구동시켜 압축기(CP)를 냉각시켜준다(S8단계).Then, the defrost completion is detected by detecting the temperature of the cooler input to the port P2 (step S4). Here, when the completion time of defrosting is detected, time counting is started (step S5), at the same time, driving of the defrosting heater HTR is stopped, and a low signal is output to the port P6 for a predetermined time (for example, 7 minutes). By driving the compressor cooling fan motor (CM) to cool the compressor (CP) (S8 step).

그리고, 상기 소정의 시간이 경과되면 다시 압축기(CP)를 구동시킨다(S9단계). 동시에 포트(P4)로의 출력(로우신호)를 차단하여 냉각팬모터(FM)는 정지상태를 유지토록 하여주며 포트(P2)로의 입력신호를 검출하여 냉각기의 온도를 검출한다(S11단계). 여기서 냉각기의 온도가 냉동실의 온도보다 낮거나 같은지를 판단한다(S12단계).When the predetermined time elapses, the compressor CP is driven again (step S9). At the same time, the output (low signal) to the port P4 is blocked to maintain the cooling fan motor FM, and the input signal to the port P2 is detected to detect the temperature of the cooler (step S11). Here, it is determined whether the temperature of the cooler is lower than or equal to the temperature of the freezer compartment (step S12).

상기 판단결과, 냉각기의 온도가 냉동실의 온도보다 같거나 낮을때에만 포트(P4)로 로우신호를 출력하여 냉각팬(FM)을 구동시켜 냉각기의 냉기가 냉동실로 투입되도록 하여준다(S13단계).As a result of the determination, the low signal is output to the port P4 only when the temperature of the cooler is equal to or lower than the temperature of the freezer compartment to drive the cooling fan FM so that the cold air of the cooler is introduced into the freezer compartment (S13).

이상에서와 같이 본 발명은 제상후 냉동실 고내 및 냉동실에 저장된 식품의 표면에 생기는 이슬을 방지할 수 있을 뿐만 아니라, 제상후 신속하게 냉동효과를 누릴 수 있는 이점이 있다.As described above, the present invention not only prevents dew from occurring on the surface of the food stored in the freezer compartment after defrosting and on the surface of the food stored in the freezer compartment, but also has an advantage of rapidly freezing after defrosting.
