본 발명은 냉장고의 히터 구동방법에 관한 것으로, 특히 전자식 냉장고에 있어서 주위환경에 따라 히터를 최적절히 동작시킴으로써 이슬맺힘을 방지하는 냉장고의 이슬맺힘 히터 구동방법에 관한 것이다.The present invention relates to a method of driving a heater of a refrigerator, and more particularly, to a method of driving a dew heater of a refrigerator which prevents dew formation by operating the heater optimally according to the surrounding environment in an electronic refrigerator.

일반적인 냉장고의 히터 구동장치는 제1도에 도시한 바와 같이, 마이크로 컴퓨터(110)는 센서부(100)의 냉동센서(102)에 의해 감지되는 데이타에 의해 구동부(120)의 릴레이(RY1,RY2)를 온시킴으로써 컴프레셔(140)와 팬(150)을 운전시키게 된다.As shown in FIG. 1, the heater driving apparatus of the general refrigerator includes the relays RY1 and RY2 of the driving unit 120 based on data detected by the freezing sensor 102 of the sensor unit 100. By turning on), the compressor 140 and the fan 150 are driven.

이후, 상기 컴프레셔(140)의 운전적산이 일정시간동안 누적이 되면, 마이크로 컴퓨터(110)는 상기 컴프레셔(140) 및 팬(150)의 운전을 중지시킴과 아울러 릴레이(RY3)를 온시켜 제상히터(160)를 운전시킨다.Thereafter, when the operation integration of the compressor 140 accumulates for a predetermined time, the microcomputer 110 stops the operation of the compressor 140 and the fan 150 and turns on the relay RY3 to defrost heater. Drive 160.

상기 제상히터(160)가 운전되는 동안 증발기(미도시)에 부착된 센서부(100)의 제상센서(101)는 증발기 주위의 온도를 감지하여 그 감지된 온도가 일정온도 이상이 되면 마이크로 컴퓨터(110)에서 릴레이(RY3)를 오프시킴으로써 상기 제상히터(160)의 운전을 중지시키게 되며, 다시 컴프레서(140)와 팬(150)을 구동하여 냉동 및 냉장을 행하게 된다.While the defrost heater 160 is operating, the defrost sensor 101 of the sensor unit 100 attached to the evaporator (not shown) senses the temperature around the evaporator and when the detected temperature is above a predetermined temperature, the microcomputer ( By turning off the relay RY3 at 110, the operation of the defrost heater 160 is stopped, and the compressor 140 and the fan 150 are driven again to perform freezing and refrigerating.

한편, 냉장고내의 차가운 공기와 외부의 따뜻한 공기가 부딪히는 공간에서 이슬맺힘점(DEW point)이 형성되어 물방울이 맺히게 되는데, 이러한 물방울의 맺힘을 방지하기 위하여 이슬맺힘점이 형성되는 곳에 이슬맺힘 방지히터(170)를 설치하여 이슬맺힘을 방지하게 된다.On the other hand, dew condensation point (DEW point) is formed in the space where the cold air in the refrigerator and the outside warm air is condensed water droplets are formed, in order to prevent the condensation of water droplets to prevent dew condensation heater (170) ) To prevent dew condensation.

이러한 이슬맺힘 방지히터(170)의 동작점을 이슬맺힘점을 형성시키는데 중요한 역할을 하는 주위의 습도와는 관계없이 센서부(100)의 외부온도센서(103)에서 감지되는 온도만을 가지고 결정하게 되는데, 일정온도 이상이면 이슬맺힘 방지히터(170)를 온시키게 되고, 일정온도 이하이면 오프시킴으로써 이슬맺힘을 제거하게 된다.The dew point preventing heater 170 is determined based on only the temperature detected by the external temperature sensor 103 of the sensor unit 100 regardless of the ambient humidity that plays an important role in forming the dew point. When the temperature is above a certain temperature, the dew condensation preventing heater 170 is turned on, and when the temperature is lower than the predetermined temperature, the dew condensation is removed.

그러나, 이와 같은 경우에 만일 실제 주위의 습도가 적어 이슬맺힘점이 아닌데도 일정온도 이상이 되면 이슬맺힘 방지히터가 구동됨으로서 불필요한 전력소모를 초래하며, 반면에 습도가 많아 이슬맺힘 방지히터가 구동되어야 하는데도 일정온도에 도달하지 않으면 구동되지 않으므로 이슬이 맺히게 되어 사용자로 하여금 불편함을 느끼게 하는 문제점이 있었다.In this case, however, if the ambient humidity is less than the dew point due to the low ambient humidity, the anti-dew heater will be driven, causing unnecessary power consumption. If it does not reach the temperature is not driven because the dew is a problem that makes the user feel uncomfortable.

따라서, 본 발명은 이러한 문제점을 감안하여, 습도센서에 의해 감지되는 습도와 외부온도센서에 의해 감지되는 온도를 반영하여 이슬이 맺히는 경우를 판단하여 그 판단결과에 의해 이슬맺힘 방지히터를 제어하는데 목적이 있는 것으로, 이와 같은 목적을 갖는 본 발명을 상세히 설명한다.Therefore, in view of the above problems, the present invention aims to determine the case of dew condensation by reflecting the humidity sensed by the humidity sensor and the temperature sensed by the external temperature sensor, and controlling the dew preventing prevention heater by the determination result. With this, the present invention having such an object will be described in detail.

본 발명 냉장고의 이슬맺힘 방지히터 구동방법은, 냉동센서에 의한 냉각제어 과정중 외부온도와 습도를 감지하여 그 감지값의 평균값을 산출하는 제1과정과, 상기 제1과정에 의하여 산출된 값에 따라 이슬맺힘 방지히터의 동작을 제어하는 제2과정으로 이루어진다.In the present invention, a method of driving a dew preventing heater of a refrigerator includes: a first process of sensing an external temperature and humidity during a cooling control process by a refrigeration sensor and calculating an average value of the detected values; and a value calculated by the first process. Accordingly, a second process of controlling the operation of the dew preventing heater is performed.

한편, 상기 제2과정은 습도와 외부온도의 산출값이 모두 낮다고 판단되면 이슬맺힘 방지히터를 오프시키는 제1단계와, 습도가 낮고 외부온도가 높다고 판단되면 추론값에 의한 이슬맺힘점인가를 판단하는 제2단계와, 상기 제2단계에 의하여 이슬맺힘점이라고 판단되면 이슬맺힘 방지히터를 온시키고 그렇지 않으면 오프시키는 제3단계와, 습도가 높고 온도가 낮다고 판단되면 상기 제3단계를 수행하는 제4단계와, 습도와 온도가 모두 높다고 판단되면 이슬맺힘 방지히터를 온시키고, 제상모드이면 히터를 오프시키는 제5단계로 이루어진다.On the other hand, the second process is the first step to turn off the dew condensation heater when it is determined that both the calculated value of the humidity and the external temperature is low, and if it is determined that the humidity is low and the external temperature is high, it is determined whether the dew point by the inference value And a third step of turning on and off the dew preventing heater if the dew point is determined by the second step, and performing the third step if the humidity is high and the temperature is low. In step 4, if it is determined that both the humidity and the temperature are high, the dew condensation heater is turned on, and in the defrost mode, the fifth step is turned off.

이와 같이 이루어진 본 발명의 작용 및 효과를 상세히 설명한다.The operation and effects of the present invention made as described above will be described in detail.

제2도는 본 발명에 의거한 냉장고의 히터 구동장치의 동작은 제1도와 동일하므로 본 발명에서 추가된 부분을 중심으로 상세히 설명한다.2 is the operation of the heater driving apparatus of the refrigerator according to the present invention is the same as FIG.

마이크로 컴퓨터(110)는 센서부(100)의 냉동센서(102)에 의해 구동부(120)의 릴레이(RY1,RY2)를 제어함으로써 컴프레셔(140)와 팬(160)을 운전시키게 되고, 또한 외부온도센서(103) 및 습도센서(104)로부터 입력되는 감지값의 평균값을 산출하게 된다.The microcomputer 110 operates the compressor 140 and the fan 160 by controlling the relays RY1 and RY2 of the driving unit 120 by the freezing sensor 102 of the sensor unit 100. The average value of the detected values input from the sensor 103 and the humidity sensor 104 is calculated.

이때, 상기 마이크로 컴퓨터(110)는 산출된 외부온도 및 습도의 평균값을 판단하게 되는데, 습도와 외부온도가 모두 낮다고 판단되면 이슬이 맺히지 않는 상태이므로 구동부(120)의 릴레이(RY4)를 오프시켜 이슬맺힘 방지히터(170)을 오프시키게 된다.At this time, the microcomputer 110 determines the average value of the calculated external temperature and humidity. If it is determined that both the humidity and the external temperature are low, dew does not form. Therefore, the relay RY4 of the driving unit 120 is turned off to remove the dew. The condensation prevention heater 170 is turned off.

또한, 습도가 낮고 외부온도가 높다고 판단되면 그 조건에 따라 이슬맺힘이 발생할 수 있으므로 추론값에 의한 이슬맺힘점인가를 판단하여 만일 이슬맺힘점이라고 판단되었을 경우 상기 이슬맺힘 방지히터(170)를 온시키게 되지만, 반면에 그렇지 않을 경우에는 이슬맺힘 방지히터(170)를 오프시키게 된다.In addition, if it is determined that the humidity is low and the external temperature is high, dew condensation may occur according to the conditions, so it is determined whether the dew condensation point by the inference value, and if it is determined that the dew condensation point heater, the dew condensation prevention heater 170 is turned on. On the other hand, otherwise, the dew preventing heater 170 is turned off.

그리고, 습도가 높고 외부온도가 낮다고 판단되면 상기에서 설명한 바와 같이 추론값에 의한 이슬맺힘점인가를 판단하여 이슬맺힘 방지히터(170)를 온 또는 오프시키게 되는 것이다.When it is determined that the humidity is high and the external temperature is low, as described above, the dew point prevention heater 170 is turned on or off by determining whether the dew point is the dew point by the inference value.

마지막으로, 습도와 외부온도가 모두 높다고 판단되면 이슬이 맺히는 확률이 매우 높으므로 상기 이슬맺힘 방지히터(170)를 온시켜 이슬맺힘을 제거하게 된다.Lastly, if it is determined that both the humidity and the external temperature is high, the probability of dew formation is very high, and thus the dew preventing prevention heater 170 is turned on to remove the dew formation.

이후, 제상모드인가를 판단하여 제상모드이면 상기 이슬맺힘 방지히터(170)를 오프시킴으로써 이슬맺힘 제거과정이 종료된다.Thereafter, it is determined whether the defrost mode is in the defrost mode, and the dew condensation removing process is terminated by turning off the dew preventing heater 170.

이와 같이 본 발명은 습도센서에 의해 감지되는 습도와 외부온도센서에 의해 감지되는 온도의 평균값을 산출하여 이 산출된 값에 의해 이슬이 맺히는 경우를 판단하게 되고, 그 판단결과에 의해 이슬맺힘 방지히터를 적절히 제어함으로써 이슬이 맺히지 않는 상태에서의 히터의 동작을 중단하게 되어 전력소모를 줄일 수 있는 효과와 아울러 이슬맺힘을 완벽히 제거할 수 있는 효과가 있게 되어 사용상의 편리성도 있게 된다.As described above, the present invention calculates an average value of the humidity sensed by the humidity sensor and the temperature sensed by the external temperature sensor to determine a case of dew condensation by the calculated value, and the anti-dew heater according to the determination result. By properly controlling, the operation of the heater is stopped in the absence of dew, thereby reducing the power consumption and the effect of completely removing the dew condensation, thereby providing convenience in use.
