Referring to FIG. 1, a refrigerator having one evaporator, one fan motor, and one temperature controller includes an evaporator (not shown), a temperature controller 2, and a fan motor 4 only in the freezer compartment. The reason why the evaporator is not shown in FIG. 1 is that the illustration of the evaporator is omitted since the evaporator has no relation with the electric circuit as the heat exchange part of the refrigerant.

도 1의 구성에 따른 냉장고의 전기적인 제어동작은 당업자에게 널리 공지되어 있기 때문에 본 명세서에서 이에 대한 상세한 설명은 생략하지만, 미설명된 도면부호를 살펴보면 다음과 같다. 즉, 도면부호 6은 냉장실 고내등이고, 8은 냉동실 고내등, 10은 냉장고 도어 스위치, 12는 제상히터, 14는 온도 휴즈, 16은 바이메탈 스위치, 18은 압축기 냉각모터, 20은 제상 타이머, 22는 PTC 서미스터, 24는 기동 콘덴서, 26은 운전 콘덴서, 28은 압축기, 30은 과부하 보호기(OLP; over load protector)이다.Since the electric control operation of the refrigerator according to the configuration of FIG. 1 is well known to those skilled in the art, a detailed description thereof will be omitted, but a description of the reference numerals is as follows. In other words, reference numeral 6 denotes a refrigerator compartment interior lamp, 8 a freezer compartment interior lamp, 10 a refrigerator door switch, 12 a defrost heater, 14 a temperature fuse, 16 a bimetal switch, 18 a compressor cooling motor, 20 a defrost timer, and 22 a PTC. Thermistor, 24 is a starting capacitor, 26 is a working capacitor, 28 is a compressor, 30 is an over load protector (OLP).

그런데, 상기와 같이 냉동실에만 증발기, 온도조절기, 냉각 팬 모터가 설치되는 냉장고는 기본적으로 냉장고의 해당 성능을 충분히 발휘하지만 다음과 같은 문제점을 가지고 있다.However, as described above, the refrigerator in which the evaporator, the temperature controller, and the cooling fan motor are installed only in the freezer compartment basically exhibits the corresponding performance of the refrigerator, but has the following problems.

즉, 냉동실에만 증발기, 냉각 팬 모터가 설치되기 때문에 냉장실에서의 고내 냉기 제어가 어렵고, 냉장실에서의 냉력이 저하되는 문제가 있다.That is, since the evaporator and the cooling fan motor are installed only in the freezer compartment, it is difficult to control the cold air in the refrigerator compartment and the cold power in the refrigerator compartment is lowered.

본 발명은 상기와 같은 문제점을 해결하기 위하여 창출된 것으로서, 냉동실 및 냉장실 각각에 증발기, 냉각 팬 모터, 온도조절기, 및 제상히터를 설치하는 경우 마이크로컴퓨터의 프로그램 제어를 통하지 않고도 이들을 간단한 하드웨어 회로구성에 의해 제어할 수 있도록 함으로써 냉장고의 성능을 향상시킨 냉장고의 제어장치를 제공함에 그 목적이 있다.The present invention has been made to solve the above problems, and in the case of installing the evaporator, the cooling fan motor, the temperature controller, and the defrost heater in each of the freezer compartment and the refrigerating compartment, they are provided in a simple hardware circuit configuration without the program control of the microcomputer.

본 발명에 따른 냉장고의 제어장치는, 마이크로컴퓨터의 프로그램 제어를 통하지 않고도 간단한 회로구성에 의해 냉동실 및 냉장실 각각에 설치된 증발기, 냉각 팬 모터, 및 제상히터를 제어할 수 있도록 한 것으로서, 도 2에 도시된 바와 같이 압축기(28)와, 냉동실 및 냉장실 각각에 설치되는 증발기(미도시), 온도조절기(2)(2'), 냉각 팬 모터(4)(4') 및 제상히터(12)(12')와, 도어 스위치(10)를 포함하는 냉장고에 있어서, 압축기(28)의 운전은 냉동실 온도조절기(2)에 의해서만 이루어지도록 냉동실 온도조절기(2)를 설치하고, 냉장실 온도조절기(2')는 냉동실 온도조절기(2)가 운전위치에 있을 때만 동작하도록 설치하며, 냉장실 제상히터(12')는 냉동실 제상히터(12)가 동작하는 동안에만 동작하도록 설치하며, 냉동실 냉각 팬 모터(4) 및 냉장실 냉각 팬 모터(4')는 냉동실 도어 스위치(10F) 및 냉장실 도어 스위치(10R)중의 어느 한 도어 스위치가 동작하면 정지하도록 설치한다. 여기서, 냉장실 온도조절기(2')는 냉동실 온도조절기(2)의 후단에 직렬로 연결되고, 냉장실 제상히터(12')는 냉동실 제상히터(12)와 병렬로 연결되며, 냉장실 냉각 팬 모터(4')는 냉장실 온도조절기(2')의 후단에 직렬로 연결된다.The control apparatus of the refrigerator according to the present invention is to control the evaporator, the cooling fan motor, and the defrost heater installed in each of the freezer compartment and the refrigerating compartment by a simple circuit configuration without the program control of the microcomputer. As described above, an evaporator (not shown), a temperature controller (2) (2 '), a cooling fan motor (4) (4') and a defrost heater (12) (12) installed in the compressor (28), a freezer compartment and a refrigerating compartment, respectively, In the refrigerator including ') and the door switch 10, the freezer compartment temperature controller 2 is installed so that the operation of the compressor 28 is performed only by the freezer compartment temperature controller 2, and the refrigerator compartment temperature controller 2'. Is installed to operate only when the freezer compartment temperature controller (2) is in the operating position, the refrigerator compartment defrost heater (12 ') is installed to operate only while the freezer defrost heater (12) is operating, the freezer compartment cooling fan motor (4) and Cold room cooling fan motor (4 ') is cold It installs so that any one door switch of the room door switch 10F and the refrigerator door switch 10R may stop when it operates. Here, the refrigerator compartment temperature controller 2 'is connected in series to the rear end of the freezer compartment temperature controller 2, and the refrigerator compartment defrost heater 12' is connected in parallel with the freezer compartment defrost heater 12, and the refrigerator compartment cooling fan motor 4 ') Is connected in series to the rear end of the refrigerator compartment temperature controller 2'.

상기와 같이 구성된 본 발명 냉장고의 제어장치의 작용을 도 2를 참조하여 설명한다.The operation of the controller of the present invention refrigerator configured as described above will be described with reference to FIG.

먼저, 압축기(28)는 도 2의 회로구성을 통해 알 수 있는 바와 같이 냉동실 온도조절기(2)가 동작하여 온(ON) 상태를 유지하고 있는 동안에만 운전되게 된다. 이는 냉동실 온도조절기(2)가 오프(OFF)되면, 상용 교류전원이 압축기(28)에 인가될 수 없기 때문이다.First, the compressor 28 is operated only while the freezer compartment temperature controller 2 operates and maintains an ON state, as can be seen through the circuit configuration of FIG. 2. This is because the commercial AC power cannot be applied to the compressor 28 when the freezer compartment temperature controller 2 is OFF.

그리고, 냉장고의 운전중에 냉동실 온도조절기(2)가 동작하여 온되고, 냉동실 및 냉장실 도어가 닫혀 있으면, 냉동실 팬 모터(4)가 동작하여 냉동실 증발기(미도시) 주위의 냉기를 냉동실 고내에서 순환시켜 냉동실 고내를 냉각시킨다. 이때, 냉장실 온도조절기(2')가 동작하여 온되고, 냉장실 도어 및 냉동실 도어가 닫혀있으면, 냉장실 팬 모터(4')가 동작하여 냉장실 증발기(미도시) 주위의 냉기를 냉장실 고내에서 순환시켜 냉장실 고내를 냉각시킨다. 여기서, 도 2의 회로구성도에 도시되어 있는 바와 같이, 상기한 냉장실 온도조절기(2')는 냉동실 온도조절기(2)의 후단에 직렬로 연결되어 있기 때문에 냉동실 온도조절기(2)가 운전위치, 즉 온되어 있을 때만 그 동작의 의미가 있게 된다. 즉, 냉동실 온도조절기(2)가 오프(동작하지 않은 상태)되어 있으면, 냉장실 온도조절기(2')에는 상용 교류전원이 인가되지 않게 된다. 따라서, 냉장실 냉각 팬 모터(4')는 냉동실 온도조절기(2)가 동작하지 않은 상태에서는 냉장실 온도조절기(2')가 동작하더라도 동작을 하지 않게 된다.When the freezer compartment temperature controller 2 is operated while the refrigerator is in operation and the freezer compartment and the refrigerator compartment door are closed, the freezer compartment fan motor 4 operates to circulate the cold air around the freezer compartment evaporator (not shown) in the freezer compartment. Cool the inside of the freezer compartment. At this time, when the refrigerator compartment temperature controller 2 'is turned on and the refrigerator compartment door and the freezer compartment door are closed, the refrigerator compartment fan motor 4' operates to circulate the cold air around the refrigerator compartment evaporator (not shown) in the refrigerator compartment compartment. Cool the inside of the refrigerator. Here, as shown in the circuit diagram of FIG. 2, since the refrigerator compartment temperature controller 2 'is connected in series with the rear end of the freezer compartment temperature controller 2, the freezer compartment temperature controller 2 is operated at the operation position, That is, the operation is meaningful only when it is on. In other words, if the freezer compartment temperature controller 2 is turned off (not operated), no commercial AC power is applied to the refrigerator compartment temperature controller 2 '. Therefore, the refrigerating compartment cooling fan motor 4 'does not operate even when the refrigerating compartment temperature controller 2' is operated while the freezer compartment temperature controller 2 is not operated.

또한, 냉장고의 운전중에 냉동실 증발기의 제상조건이 성립되면, 냉동실 제상히터(12)에 의해 냉동실 증발기의 제상이 이루어진다. 이때, 냉장실 증발기에서도 제상조건이 성립되면, 냉장실 제상히터(12')에 의해 냉장실 증발기의 제상이 이루어지는데, 이 경우 냉동실에서의 제상시간이 경과하여 냉동실의 제상이 종료하면, 도 2의 회로구성에 의해 냉장실에서의 제상도 종료되게 된다. 이는 냉동실에서의 제상시간이 경과하면, 제상타이머(20)를 경우하여 상용 교류전원이 냉장실 제상히터(12')에 인가되지 못하기 때문이다. 따라서, 냉장실 증발기의 제상은 냉동실 제상히터(12)의 온 시간내에서만 이루어지게 된다.In addition, when the defrosting condition of the freezer compartment evaporator is established during operation of the refrigerator, the freezer compartment defrost heater 12 defrosts the freezer compartment evaporator. At this time, if the defrosting condition is also established in the refrigerating compartment evaporator, defrosting of the refrigerating compartment evaporator is performed by the refrigerating compartment defrost heater 12 ′. Defrost in the refrigerating chamber is also completed by this. This is because when the defrosting time in the freezing chamber elapses, the commercial AC power is not applied to the refrigerating chamber defrost heater 12 ′ in the case of the defrost timer 20. Therefore, the defrost of the refrigerating compartment evaporator is performed only within the on time of the freezer compartment defrost heater 12.

더욱이, 도 2의 회로구성에 의해 알 수 있는 바와 같이, 냉동실 냉각 팬 모터(4) 및 냉장실 냉각 팬 모터(4')는 그 동작중에 냉동실 도어 또는 냉장실 도어가 열려 그 스위치(10F)(10R)가 동작하게 되면, 냉동실 냉각 팬 모터(4) 및 냉장실 냉각 팬 모터(4')에는 전원이 인가되지 않게 되어 동작을 멈추게 된다. 따라서, 냉장고 도어가 열릴 때, 냉각 팬 모터(4)(4')의 동작에 따른 고내의 냉기가 외부로 유출되는 것이 방지된다.Moreover, as can be seen by the circuit configuration of Fig. 2, the freezer compartment cooling fan motor 4 and the refrigerating compartment cooling fan motor 4 'open the freezer compartment door or the refrigerating compartment door during its operation, and their switches 10F and 10R. When is operated, power is not applied to the freezer compartment cooling fan motor 4 and the refrigerating compartment cooling fan motor 4 'and the operation is stopped. Therefore, when the refrigerator door is opened, cold air in the refrigerator caused by the operation of the cooling fan motors 4 and 4 'is prevented from leaking to the outside.

이로써, 본 발명 냉장고의 제어장치에 따르면, 냉동실 및 냉장실 각각에 증발기, 온도조절기, 냉각 팬 모터, 제상히터가 개별적으로 설치되어 있다 하더라도, 간단하고도 단순한 회로구성에 의해 제어된다.Thus, according to the control device of the refrigerator of the present invention, even if an evaporator, a temperature controller, a cooling fan motor, and a defrost heater are separately provided in each of the freezer compartment and the refrigerating compartment, they are controlled by a simple and simple circuit configuration.

이상에서 설명한 바와 같이 본 발명에 따른 냉장고의 제어장치는, 냉동실 및 냉장실 각각에 증발기, 냉각 팬 모터, 온도조절기, 및 제상히터를 설치하는 경우 마이크로컴퓨터의 프로그램 제어를 통하지 않고도 이들을 간단한 회로구성에 의해 제어할 수 있도록 함으로써 냉장고의 성능 및 기능을 향상시키는 효과를 제공한다.As described above, in the case of installing the evaporator, the cooling fan motor, the temperature controller, and the defrost heater in each of the freezer compartment and the refrigerating compartment, the controller of the refrigerator according to the present invention can be controlled by a simple circuit configuration without the program control of the microcomputer. By allowing control, it provides the effect of improving the performance and function of the refrigerator.

한편, 상술한 바와 같은 본 발명 냉장고의 제어장치는 상기 실시예에 한정되지 않고 본원 발명의 정신과 범위를 이탈하지 아니하고 많은 제조변형을 가하여 실시할 수 있음은 물론이다.On the other hand, the control device of the present invention as described above is not limited to the above embodiment can be carried out by applying a number of manufacturing modifications without departing from the spirit and scope of the present invention.
