본 고안은 냉장고의 냉기순환 FAN 제어장치의 개량에 관한 것으로, 증발기 온도가 냉동실 온동보다 높을 때에는 FAN이 동작하지 않도록 하고, 증발기 온도가 냉동실 온도보다 낮을 때에는 FAN이 동작하도록 하여 냉장고의 효율을 증대시키도록 된 냉장고의 냉기순환 FAN 제어장치인 것이다.The present invention relates to an improvement of the cold air circulation fan control device of the refrigerator, and to prevent the FAN from operating when the evaporator temperature is higher than the freezer temperature, and to operate the FAN when the evaporator temperature is lower than the freezer temperature, thereby increasing the efficiency of the refrigerator. It is a cold air fan control device of the refrigerator.
종래의 냉장고에 있어서는 압축기와 FAN을 동시에 온·오프하도록 되어 있어서 증발기의 온도가 냉동실 온도보다 높을 경우에도 FAN이 동작하여 냉동실의 온도를 상승시키는 결과가 되어 냉동실의 식품을 상하게 할 우려가 있을 뿐만 아니라 불필요한 전력을 소비하는 결점이 있었으며, 또한, 평상시에는 FAN을 동작시키다가 제상개시시와 동시에 FAN을 정지시키고, 제상완료후에는 시간이 경과하여 증발기의 온도가 저하하면 그때 FAN을 동작시키는 것이 있었으나, 이러한 방식은 제상개시시에 증발기의 온도가 낮은데도 불구하고, 팬이 정지되므로 냉장고의 효율을 증대시키지 못하였고, 또한 제상완료후에는 냉동실의 온도와는 관계없이 증발기의 온도가 어느 정도 저하하면 팬이 동작하도록 되어 있어서, 증발기의 온도가 냉동실의 온도보다 높을 경우에는 냉동실의 온도가 상승하게 되고, 증발기의 온도가 냉동실의 온도보다 낮을 경우에는 팬이 그동안 동작하지 못하여서 냉동효과가 저하되는 등의 결점이 있었던 것이다.In the conventional refrigerators, the compressor and the fan are simultaneously turned on and off, and even when the evaporator temperature is higher than the freezer temperature, the fan may operate to raise the temperature of the freezer, which may damage the food in the freezer. There was a drawback of consuming unnecessary power.In addition, FAN was normally operated, and the FAN was stopped at the same time as the start of defrosting, and when the temperature of the evaporator decreased after the completion of defrosting, the FAN was operated at that time. This method does not increase the efficiency of the refrigerator because the fan is stopped even though the evaporator temperature is low at the start of defrosting, and after completion of the defrost, the fan is reduced if the temperature of the evaporator decreases to some extent regardless of the temperature of the freezer compartment. Is operated so that the temperature of the evaporator is higher than the temperature of the freezer compartment. Is the temperature of the freezing chamber and rises, when the temperature of the evaporator is lower than the temperature of the freezing chamber will have been a disadvantage such that the fan is not operating meantime mothayeoseo lowering the freezing effect.
본 고안은 이러한 종래의 결점을 해결하기 위하여 안출한 것으로, 압축기와 팬을 각각 따로 동직시키되 제상개시시나, 제상완료시에 관계없이 증발기의 온도가 냉동실의 온도보다 낮으면 팬이 동작하도록 하도, 증발기의 온도가 냉동실의 온도보다 높으면 팬이 정지되도록 하므로서 종래의 제반결점을 해결한 것으로, 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been made to solve the above-mentioned drawbacks. Even though the compressor and the fan are moved separately, the fan is operated when the temperature of the evaporator is lower than the temperature of the freezer regardless of the start of defrosting or completion of defrosting. When the temperature is higher than the temperature of the freezer compartment to solve the conventional defects by stopping the fan, it will be described in detail by the accompanying drawings as follows.
냉동실 온도를 감지하는 정특성 온도 감응소자(PTC1)가 연결된 연산증폭기(PO1)와, 증발기의 온도를 감지하는 정특성 온도 감응소자(PTC2)가 연결된 연산증폭기(OP2)를 연결시킨 제상회로(H)를 다이오드(D1, D2)로 접속하고, 트랜지스터(Q2), 다이오드(D4)를 통하여 압축기(CP)를 제어하는 트레이악(TD1)의 게이트에 연결시킨 회로에 있어서, 접속점 (A)와 (B)를 연산증폭기(PO3)의 비반전단자(+) 및 반전단자(-)에 각각 연결시키고, 연산증폭기(OP3)의 출력은 저항(R1, R10), 트랜지스터(Q2), 다이오드(D4) 및 트라이악(TD2)으로 된 공지의 FAN 구동부(F)에 연결시킨다.The operational amplifier (PO 1 ) connected to the positive temperature sensing element (PTC 1 ) detecting the freezer compartment temperature and the operational amplifier (OP 2 ) connected to the constant temperature sensing element (PTC 2 ) sensing the temperature of the evaporator are connected. The defrost circuit H is connected to the diodes D 1 and D 2 , and is connected to the gate of the tray ac TD 1 controlling the compressor CP through the transistors Q 2 and D 4 . In the circuit, the connection points (A) and (B) are connected to the non-inverting terminal (+) and the inverting terminal (-) of the operational amplifier (PO 3 ), respectively, and the output of the operational amplifier (OP 3 ) is a resistor (R 1). , R 10 ), transistor Q 2 , diode D 4 and triac TD 2 to a known FAN driver F.

그리고 R2=R5, R3=R6, R4=R7로 저항치를 설정하고 PTC1과 PTC2는 동일한 특성을 갖는 소자로 구성한다.Then, the resistance value is set to R 2 = R 5 , R 3 = R 6 , and R 4 = R 7 , and PTC 1 and PTC 2 are composed of devices having the same characteristics.
이와 같은 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
먼저 제3도에 의하여 종래의 경우를 설명하면, 제3도는 압축기(CP)와 FAN이 트라이악(TD) 하나로 동시에 온·오프되고 제상회로(H)와는 역작용하도록 구성된 회로로서, 제4도의 t1에서와 같이 증발기 온도가 어느 한계치에 도달하면 제상회로(H)가 동작(히이터 동작)하고 압축기(CP)와 FAN은 "오프"되다가 히이터의 가열로 인하여 증발기의 온도가 상승하면(제상동작완료후) 아직 냉동실의 온도가 낮은데도 불구하고, 제상회로(H)는 동작을 중지하고, 연산 증폭기(OP1)의 출력을 트랜지스터(Q2)에 공급시켜 트라이악(TD)을 구동시키므로 압축기(CP)와 FAN은 동시에 동작을 하게 된다.First, the conventional case will be described with reference to FIG. 3, and FIG. 3 is a circuit configured to simultaneously turn on / off the compressor CP and the FAN with one triac TD and act against the defrost circuit H. When the evaporator temperature reaches a certain limit as in t 1 , the defrost circuit H is activated (heater operation), the compressor CP and the FAN are “off”, and when the temperature of the evaporator rises due to the heating of the heater (defrost After the operation is completed), even though the freezer temperature is still low, the defrost circuit H stops the operation and supplies the output of the operational amplifier OP 1 to the transistor Q 2 to drive the triac TD. As a result, the compressor CP and the FAN operate simultaneously.
그리하여 증발기의 높은 온도를 FAN으로 냉동실, 냉장실에 확산시키게 되어 냉동실의 식품을 상하게 할 우려가 있을 뿐만 아니라 불필요한 전략을 소비하는 결과가 된다.Thus, the high temperature of the evaporator is diffused into the freezer compartment and the refrigerating compartment by FAN, which may not only damage the food in the freezer compartment but also consume unnecessary strategies.
다음에 본 고안에 대하여 설명하면, 제1도와 같이 연산증폭기(OP3)는 증발기의 온도가 냉동실의 온도보다 높을 경우에는 정특성 온도 감응소자의 등가저항 값이 RPTC1<RPTC2가 되고, R2=R5이므로 A점의 전압이 B점의 저압보다 낮게 되어 연산증폭기(OP3)의 출력은 로우 레벨이 되어 FAN이 동작하지 않게 되고, 증발기의 온도가 냉동실의 온도 보다 낮은 경우에는 RPTC1<RPTC2가 되어, A점의 전압이 B점의 전압보다 높게 되므로 연산증폭기(OP3)의 출력전압이 트랜지스터(Q1)를 구동시키지 못하게 되는 점(제2도 t2)에서 FAN은 "오프"된다.Next will be described with respect to the present invention, the case is higher than as a first assist the operational amplifier (OP 3) is the temperature of the temperature of the evaporator, the freezer compartment, the equivalent resistance value of the positive characteristic temperature sensitive device, and the R PTC1 <R PTC2, R Since 2 = R 5 , the voltage at point A is lower than the low pressure at point B. The output of the operational amplifier OP3 is at a low level, and the fan does not operate. When the temperature of the evaporator is lower than the temperature of the freezer compartment, R PTC1 < R PTC2 , so that the voltage at point A becomes higher than the voltage at point B, so that the FAN is "off" at the point where the output voltage of the operational amplifier OP 3 does not drive the transistor Q 1 (FIG. 2 (t 2 )). "do.
한편 압축기(OP)의 "오프"로 제상회로(H)가 가동되어 제상작용이 계속됨에 따라 증발기의 온도는 점차 증가하다가 일정 온도에 도달하면(제3도 t3) 제상작용은 중단되고, 압축기(CP)가 동작하게 된다.On the other hand, as the defrosting circuit (H) operates with the "OFF" of the compressor (OP) and the defrosting continues, the temperature of the evaporator gradually increases, and when the temperature reaches a certain temperature (FIG. 3 t 3 ), the defrosting is stopped. The compressor CP is operated.
그러나 이 순간에는 아직 냉동실의 온도는 낮은 상태이고, 증발기의 온도는 높은 상태이므로, 연산증폭기(OP3)의 출력이 로우 레벨이어서 FAN은 동작하지 않게 된다.However, at this moment, since the temperature of the freezer is still low and the temperature of the evaporator is high, the output of the operational amplifier OP 3 is at a low level so that the FAN does not operate.
따라서 팬은 동작하지 않고, 압축기(CP)만 동작하게 되며, 얼마후에 냉동실과 증발기의 온도차에 의하여 연사증폭기(OP3)의 출력이 하이레벨이 되는 순간(제2도의 t4순간) FAN은 동작을 시작하게 된다.Thus the fan is not operating, the compressor (CP) only and to operate, the output moment is at a high level (second-degree t 4 time) of the CS amplifier (OP 3) by time later on the temperature difference between the freezing chamber and the evaporator FAN operates Will start.
이와 같이 냉동실의 온도와 증발기의 온도를 상호 비교하여 압축기의 동작에 관계없이 불필요한 경우에는 FAN을 중지시키고 필요한 경우에만 FAN을 동작시키므로서 냉동효과를 가증시키고, 불필요한 전력소모를 방지하며, 또한 냉장실의 온도를 일정하게 유지하는 효과가 있는 것이다.Thus, by comparing the temperature of the freezer compartment and the temperature of the evaporator, it stops the FAN when it is unnecessary regardless of the operation of the compressor and operates the FAN only when necessary, thereby increasing the freezing effect and preventing unnecessary power consumption. The effect is to keep the temperature constant.
