본 고안은 직냉식의 기능에 간냉식의 강제 대류 방식을 추가하여 냉장고의 고내온도차를 보상하는 회로로서,특히 냉매사이클과는 별개의 대류팬 및 온도감지소자를 냉장고의 상, 하층에 설치하여 상, 하층의 온도차에 따라 팬을 온. 오프시키므로써 냉장고의 고내온도차를 보상하도록 하는 냉장고의 팬모터 제어회로에 관한 것이다.The present invention is a circuit for compensating for the high temperature difference of a refrigerator by adding an intercooled forced convection method to a direct cooling function, and in particular, by installing a convection fan and a temperature sensing element separate from the refrigerant cycle in the upper and lower layers of the refrigerator. The fan according to the temperature difference. The present invention relates to a fan motor control circuit of a refrigerator for turning off the high temperature difference of the refrigerator.
냉장고에는 크게 간냉식(냉기강제순환방식)및 직냉식(자연대류방식)으로 구별되는데, 간냉식은 팬에 의해 냉기를 강제적으로 순환시켜 주므로써 냉장고의 상. 하층 고내온도차가 적어 장시간 식품보관에 유리하나 재빙시간이 길고 냉장실로 냉기를 보내주는 냉기통로의 댐퍼구성등이 복잡한 문제점이 있었다.There are two types of refrigerators: intercooled (cold forced circulation) and direct cooling (natural convection), which are circulated in the refrigerator by forcibly circulating cold air by a fan. The low temperature difference in the lower floor is advantageous for food storage for a long time, but there is a complicated problem such as long freezing time and configuration of damper of the cold air passage that sends cold air to the refrigerating chamber.
한편, 직냉식은 재빙시간이 짧고 별도의 냉장실 냉기통로를 위한 댐퍼구성이 간단하나 냉기의 순환이 느려 냉장고 상, 하층의 고내온도차가 심해져 보관식품에 이슬 및 성에가 생기기 때문에 장기간 식품을 보관할 수없는 문제점이 있었다.On the other hand, direct cooling has a short freezing time and a simple damper configuration for a separate cold room cold passage.However, due to the slow circulation of cold air, the temperature difference between the upper and lower floors of the refrigerator increases, causing dew and frost to the stored food. There was this.
따라서, 본고안은 상기의 문제점을 해결하기 위해 안출된 것으로서, 직냉식의 기능에 간냉식의 강제대류방식을 도입하므로써 간단한 구성으로 냉장고의 고내온도차를 보상하고, 제빙시간을 단축할 수 있는 냉장고의 팬모터제어회로를 제공함에 그 목적이 있다.Therefore, the present invention was devised to solve the above problems, and the fan motor of the refrigerator that can compensate for the difference in the internal temperature of the refrigerator and shorten the ice making time by adopting the intercooled forced convection method in the direct cooling function. The purpose is to provide a control circuit.

The control circuit unit 21 is a circuit unit for controlling the on / off of the convection fan motor 7 according to the temperature difference sensed by the temperature sensing elements 8 and 9 in the refrigerator. If abnormal, the contact CP 3 is turned on to drive the fan motor 7.
제3도는 제2도의 제어회로부(21) 의 상세회로도로써, 전원트랜스(T1), 정류회로부(30) 및 평활콘덴서(C2)로구성된 전원부(31)의 출력을 저항(R2-R4), 가변저항(VR1)과 냉장고 고내상층 온도감지소자(8)및 트랜지스터(Q1)로 구성된 냉장고 고내의 상층온도를 감지하는 온도감지부(32)와 저항(R5-R7), 가변저항(VR2),냉장고 고내하층은 온도감지소자(9)및 트랜지스터(Q2)로 구성된 냉장고 고내의 하층온도를 감지하는 온도감지부(33)의 입력에 각각 연결하고, 상기한 온도감지부(32,33)의 애미터 출력이 각 입력단(I1, I2)에 접속된 비교증폭부(34)의 출력을 스위칭회로(35)를 통해 팬모터(7)를 구동시키는 릴레이(RLY)로 구성된 팬모터구동부(36)에 연결 구성하였다.FIG. 3 is a detailed circuit diagram of the control circuit unit 21 of FIG. 2 , and outputs the outputs of the power supply unit 31 composed of the power supply transformer T 1 , the rectifier circuit unit 30, and the smoothing capacitor C 2 to the resistors R 2 -R. 4 ), the temperature sensing unit 32 and the resistors R 5 -R 7 for detecting the upper temperature of the refrigerator compartment composed of the variable resistor VR 1 and the refrigerator high inner layer temperature sensing element 8 and the transistor Q 1 . , Variable resistance (VR 2 ), the refrigerator high-lower layer is connected to the input of the temperature sensing unit 33 for sensing the lower temperature of the inside of the refrigerator consisting of the temperature sensing element (9) and transistor (Q 2 ), respectively, Relays for driving the fan motor 7 through the switching circuit 35 the output of the comparison amplifier 34 connected to the respective input terminals I 1 and I 2 by the emitter outputs of the sensing units 32 and 33 ( RLY) was configured to connect to the fan motor drive unit 36.
상기한 제어회로부(21)의 동작을 설명하면 다음과 같다.The operation of the control circuit unit 21 will be described below.
냉동실의 온도제어용 써모스태트(11)의 냉장고 고내 온도감지에 따라 제1도에 도시된 냉동실(1)의 냉각기를 온, 오프 시켜주므로써 냉기의 순환이 자연대류식으로 이루어지면, 냉장고 고내의 상층 및 하층에 각각 설치된 온도감지소자인 써어미스터(8,9)가 상층 및 하층의 고내온도를 감지하고, 감지된 상, 하층의 온도차가 동일하거나 설정온도 범위내에 있으면 트랜지스터(Q1,Q2)가 모두 온되거나 오프되어 동일전위의 출력이 비교증폭부(34) 의 입력단(I1, I2) 에 입력되므로 비교증폭부(34) 의 출력은 로우상태(L)로 되며, 구동릴레이(RLY) 의 코일에 전류가 흐르지 않아 릴레이(RLY)의 접점(CP3)은 오프되므로 대류팬모터(7)는 구동되지 않는다.According to the temperature detection of the freezer compartment thermostat 11 of the freezer compartment, the cooler of the freezer compartment 1 shown in FIG. 1 is turned on and off, so that the circulation of the cold air is naturally convection. And thermistors (8, 9), which are temperature sensing elements respectively installed in the lower layer, detect the high internal temperature of the upper and lower layers, and if the detected temperature difference between the upper and lower layers is the same or within a set temperature range, the transistors (Q 1 , Q 2 ). Are all turned on or off so that the output of the same potential is input to the input terminals I 1 and I 2 of the comparison amplifier 34, so that the output of the comparison amplifier 34 is in a low state L and the driving relay RLY. Since no current flows in the coil of the relay RCP, the contact CP 3 of the relay RLY is turned off, so that the convection fan motor 7 is not driven.
그러나, 상층의 온도감지소자(8)와 하층의 온도감지소자(9)가 설정온도이상의 온도차를 감지하면, 트랜지스터(Q1)가 온이 되거나 트랜지스가(Q2)가 오프되고, 트랜지스터(Q,)가 오프되거나 트랜지스터(Q2)가 온이되므로 비교증폭부(34)의 입력단(I1, I2)에는 서로 다른 전원에 인가되며, 비교증폭부(34)의 출력은 하이상태(H)가 되어 구동릴레이(RLY)의 코일에 전류가 흐르므로 릴레이(RLY)의 접점(CP3)이 온이되고, 팬모터(7)가 구동하여 고내의 상층 및 하층의 온도차를 없애기 위하여 냉매를 강재 순환시키게 한다.However, when the upper temperature sensing element 8 and the lower temperature sensing element 9 detect a temperature difference higher than the set temperature, the transistor Q 1 is turned on or the transistor Q 2 is turned off and the transistor ( Since Q,) is turned off or transistor Q 2 is turned on, the input terminals I 1 and I 2 of the comparison amplifier 34 are applied to different power sources, and the output of the comparison amplifier 34 is in a high state ( H) and current flows in the coil of the driving relay RLY, so that the contact CP 3 of the relay RLY is turned on, and the fan motor 7 is driven to remove the temperature difference between the upper and lower layers in the refrigerator. To circulate steel.
직냉식의 단점인 자연대류 방식에 의한 고내온도차로 이슬 및 성에발생으로 인해 식품을 장기보관할 수 없었으나 본고안에서는 간냉식의 장점인 팬모타의 대류에 의해 고내온도분포를 동일하게 유지시켜 줄 수 있으므로 식품의 장기간 보관에 유리할 뿐만아니라 간냉식의 단점인 제빙시간을 단축시킬 수 있다.Due to the high temperature difference by natural convection method, which is a disadvantage of direct cooling, food could not be stored for a long time due to dew and frost.However, in this paper, it is possible to maintain high temperature distribution because of convection of fan motor, which is the advantage of liver cooling. Not only is it advantageous for long-term storage, but it also shortens the ice making time which is a disadvantage of intercooling.
또한, 고내의 온도분포가 동일하게 유지되어야 하는 약품보관 및 정밀화학용 제품보관 냉장고에 응용하므로써, 온도차에 의한 보관제품의 변질을 방지할 수 있어서 일반식품보관 및 산업용에도 다목적으로 응용할수 있다.In addition, it is possible to prevent the deterioration of the storage product due to the temperature difference by applying to the drug storage refrigerator for chemical storage and fine chemical products that must maintain the same temperature distribution in the refrigerator, it can be applied to general food storage and industrial purposes.
