이러한 종래의 냉장고에서 냉장실과 냉동실은 표준 온도조건에서 각각 3℃, -18℃ 정도를 유지하도록 설정되어 있는데, 하나의 열원(냉각기)에서 2개의 온도대역을 제어하는데 한계가 있어 냉장고의 에너지효율을 저하시키는 문제점이 있었다. 즉 하나의 냉각기에 의해서 냉동실과 냉장실을 전술한 소정의 온도대역으로 제어해야 하는데, 냉각기에서 생성된 냉기는 냉동실과 냉장실로 분배되어 공급되므로 냉동실과 냉장실을 함께 신속하게 냉각시키기 어려운 문제점이 있었고, 냉각 중에 도어의 잦은 개폐로 어느 실의 급격한 온도상승이 발생할 경우 신속하게 그 실의 냉각을 수해할 수 없는 문제점이 있었다.In the conventional refrigerator, the refrigerator compartment and the freezer compartment are set to maintain about 3 ° C. and −18 ° C. under standard temperature conditions, respectively, and there is a limit to controlling two temperature bands in one heat source (cooler), thereby improving energy efficiency of the refrigerator. There was a problem of deterioration. That is, one freezer controls the freezer compartment and the refrigerating compartment in the above-mentioned predetermined temperature range, and since the cold air generated by the cooler is distributed and supplied to the freezer compartment and the refrigerating compartment, it is difficult to quickly cool the freezer compartment and the refrigerating compartment together. Frequent opening and closing of the door during the sudden temperature rise of any one room there was a problem that can not quickly cool the room.
따라서, 본 발명은 이러한 문제점들을 해결하기 위한 것으로, 본 발명의 주목적은 냉동실과 냉장실에 별도의 냉각기를 설치하고 냉동실과 냉장실을 별도로 제어하도록 구성함으로써 각 실을 신속하게 냉각시킬 수 있을 뿐만 아니라 어느 실이라도 온도상승이 발생할 경우 신속하게 대응하여 냉각시킬 수 있는 냉장고의 제어 방법을 제공하는 것이다.Therefore, the present invention is to solve these problems, the main object of the present invention is to install a separate cooler in the freezer compartment and the refrigerating compartment and configured to control the freezer compartment and the refrigerating compartment separately to quickly cool each chamber as well as any chamber Even if the temperature rise occurs to provide a control method of the refrigerator that can be quickly cooled correspondingly.

이하에서는 첨부도면을 참조하면서 본 고안의 바람직한 실시예를 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.
먼저, 제4, 5, 6도를 참조하여 본 발명에 따른 냉장고를 설명한다. 제4도에 도시한 바와 같이, 본 발명에 따른 냉장고(20)는 단열구조의 냉장고본체(21)의 내부에 상호간의 냉기혼합이 일어나지 않도록 상호 구획된 하측의 냉동실(22)과 상측의 냉장실(23)이 형성된다. 이러한 냉동실(22)과 냉장실(23)은 중간격벽(24)에 의해 구획되며, 각각 냉동실도아(25)와 냉장실도아(26)에 의해 개폐된다. 즉, 종래의 냉장고와 달리 냉동실과 냉장실을 연통시키는 냉기유로가 없으며, 중간격벽에도 귀환로가 형성되지 않는다. 냉장실(23)의 후벽에는 제1냉각기(27)와 냉장실팬(28)이 설치되며, 냉동실(22)의 후벽에는 제2냉각기(29)와 냉동실팬(30)이 설치된다. 본 명세서에서 냉동실팬과 냉장실팬은 팬모타를 포함하는 개념이다. 그리고 냉장고본체(21)의 하측에 압축기(31)가 설치된다.First, the refrigerator according to the present invention will be described with reference to FIGS. 4, 5, and 6. As shown in FIG. 4, the refrigerator 20 according to the present invention includes a lower freezing compartment 22 and an upper refrigerating compartment which are mutually partitioned so that cold air mixing does not occur inside the refrigerator body 21 having a heat insulating structure. 23) is formed. The freezer compartment 22 and the refrigerating compartment 23 are partitioned by an intermediate partition 24, and are opened and closed by a freezer compartment door 25 and a refrigerating compartment door 26, respectively. That is, unlike the conventional refrigerator, there is no cold air path communicating the freezer compartment and the refrigerating compartment, and no return path is formed in the intermediate partition. The rear wall of the refrigerating chamber 23 is provided with a first cooler 27 and a refrigerating chamber fan 28, and the rear wall of the refrigerating chamber 22 is provided with a second cooler 29 and a freezing chamber fan 30. In the present specification, the freezer compartment fan and the refrigerating compartment fan are concepts including a fan motor. And the compressor 31 is installed below the refrigerator main body 21.
이러한 본 발명에 따른 냉장고의 사이클 구성은 제5도에 도시한 바와 같다. 즉, 압축기(31), 응축기(32), 모세관(33), 그리고 제1냉각기(27)와 제2냉각기(29)가 냉매관(34)에 의해 차례로 연결되어 폐회로를 구성하며, 제1냉각기(27)와 제2냉각기(29)의 부근에는 냉장실팬(28)과 냉동실팬(30)이 각각 설치된다. 특히 제1냉각기(27)와 제2냉각기(29)는 직렬로 배치되어 제1냉각기(27)를 통과한 모든 냉매가 제2냉각기(29)를 통과하도록 구성된다. 냉매는 화살표로 나타낸 바와 같이, 냉매관(34)의 내부를 흐르면서 상태변화를 하며, 특히 제1냉각기(27)와 제2냉각기(29)를 통과하면서 증발되어 이를 통과하는 공기로부터 열을 흡수하여 냉기를 생성한다. 생성된 냉기는 냉장실팬(28)과 냉동실팬(30)의 작동에 의해 냉동실(22)과 냉장실(23)로 공급되는 것이다.The cycle configuration of the refrigerator according to the present invention is as shown in FIG. That is, the compressor 31, the condenser 32, the capillary tube 33, and the first cooler 27 and the second cooler 29 are sequentially connected by the refrigerant pipe 34 to form a closed circuit, and the first cooler The refrigerator compartment fan 28 and the freezer compartment fan 30 are respectively provided in the vicinity of the 27 and the second cooler 29. In particular, the first cooler 27 and the second cooler 29 are arranged in series so that all the refrigerant passing through the first cooler 27 passes through the second cooler 29. As shown by the arrow, the refrigerant changes state as it flows through the inside of the refrigerant pipe 34, and in particular, the refrigerant absorbs heat from the air that is evaporated and passes through the first cooler 27 and the second cooler 29. Create cold air. The generated cold air is supplied to the freezing compartment 22 and the refrigerating compartment 23 by the operation of the refrigerating compartment fan 28 and the freezing compartment fan 30.
이러한 냉장고에서 냉매는 단일(單一)냉매, 예를 들면 CFC-12, 또는 HFC-134a 등이 사용된다. 이러한 냉매의 상변화 과정을 좀더 상세하게 설명하면 다음과 같다. 먼저 압축기(31)에서 냉매는 고온 고압으로 압축되고, 압축된 냉매는 응축기(32)를 흐르면서 주위와의 열교환을 통해 응축된다. 이렇게 응축된 냉매는 모세관(33) 또는 팽창밸브를 통과하면서 감압되어 제1냉각기(27)와 제2냉각기(29)를 통과하면서 증발된다. 제1냉각기(27)와 제2냉각기(29)는 직렬로 배치되어 있고, 이들 사이에는 아무런 구조물이 없으므로 제1냉각기(27)를 통과한 냉매의 전부가 곧바로 제2냉각기(29)를 통과하게 된다. 이때 제1냉각기(27)를 통과하면서 냉매의 일부가 증발되고 제2냉각기(29)를 통과하면서 냉매의 나머지가 증발되어 전부 가스상태로 되는 것이다. 이렇게 증발된 냉매는 압축기(31)에 흡입됨으로써 사이클을 구성하고 이러한 사이클은 압축기의 운전에 따라 반복된다. 한편, 냉매가 증발되면서 냉각기 주위의 공기로부터 열을 흡수하게 되는데, 냉장실팬(28)과 냉동실팬(30)의 운전으로 고내의 공기가 제1냉각기(27)와 제2냉각기(29)를 지나게 되고 열을 빼앗기면서 생성된 냉기는 제4도에 화살표로 도시한 바와 같이, 다시 고내로 공급되어 냉장실과 냉동실을 냉각시키는 것이다.In such a refrigerator, a single refrigerant, for example, CFC-12, HFC-134a, or the like is used. The phase change process of the refrigerant will be described in more detail as follows. First, in the compressor 31, the refrigerant is compressed to high temperature and high pressure, and the compressed refrigerant flows through the condenser 32 to condense through heat exchange with the surroundings. The refrigerant condensed as described above is decompressed while passing through the capillary tube 33 or the expansion valve to be evaporated while passing through the first cooler 27 and the second cooler 29. Since the first cooler 27 and the second cooler 29 are arranged in series, and there is no structure between them, all of the refrigerant passing through the first cooler 27 passes directly through the second cooler 29. do. At this time, a portion of the refrigerant is evaporated while passing through the first cooler 27, and the rest of the refrigerant is evaporated while passing through the second cooler 29, thereby becoming a gas state. The refrigerant evaporated in this way constitutes a cycle by being sucked into the compressor 31, and the cycle is repeated according to the operation of the compressor. On the other hand, the refrigerant is evaporated to absorb heat from the air around the cooler, the operation of the refrigerator compartment fan 28 and the freezer compartment 30 to pass the air in the interior of the first cooler 27 and the second cooler 29. The cold air generated as the heat is taken away is supplied to the inside of the refrigerator again to cool the refrigerating compartment and the freezing compartment, as shown by arrows in FIG.
이와 같이, 2개의 냉각기와 2개의 팬을 가지면서 작동유체로서 단일냉매를 사용하는 시스템을 본 명세서에서 H.M.싸이클이라 정의한다. 이 H.M.싸이클은 냉각기들 사이에 기액분리기나 냉매의 유동방향을 제어하기 위한 밸브와 같은 부품이 필요 없게 되고 냉각기를 직렬로 배치할 수 있어 냉동사이클을 위한 배관 구성이 매우 단순해진다. 또한 단일냉매를 사용하므로 제조공정에서 혼합냉매 사용시와 같은 냉매 봉입량의 산포에 따른 성능변화가 크지 않아 양산(量産)에 매우 유리하다.As such, a system having two coolers and two fans and using a single refrigerant as the working fluid is defined herein as an H.M. cycle. This H.M. cycle eliminates the need for components such as gas-liquid separators or valves to control the flow direction of the refrigerant between the chillers and allows the chillers to be arranged in series, simplifying the piping configuration for the refrigeration cycle. In addition, since a single refrigerant is used, the performance change according to the dispersion of the refrigerant charge amount as in the case of using a mixed refrigerant in the manufacturing process is not very large, which is very advantageous for mass production.
다음에는 제6도를 참조하여 본 발명의 H.M.싸이클에 따른 냉장고의 제어부의 구성을 설명한다. 제어부(35)의 입력측에는 도어스위치(36), 냉장실온도센서(37), 냉동실온도센서(38), 외기온도센서(39), 그리고 제1냉각기표면온도센서(40)와 제2냉각기표면온도센서(40')가 접속되어, 도어의 개폐여부, 냉동실의 온도, 냉장실의 온도, 제1냉각기와 제2냉각기의 표면온도를 각각 검지하여 전기신호로써 제어부(35)에 전달한다. 또한 제어부(35)의 출력측에는 압축기(31), 냉장실팬(28 및 냉동실팬(30)을 각각 온,오프시키기 위한 제1스위치(41)와, 제2스위치(42), 그리고 제3스위치(43)가 전기접속되어, 전술한 입력신호에 따라 작동한다. 즉, 제1스위치(41)와 제2스위치(42), 그리고 제3스위치(43)는 상기한 각 센서들로부터 입력된 신호에 따라 스위치제어부(44)에 의해 제어되어 각각 압축기(31)와 냉동실팬(28) 및 냉장실팬(30)을 온,오프시키는 것이다. 따라서 압축기와 냉동실팬 및 냉장실팬을 각각 독립적으로 제어하는 것이 가능하다.Next, the configuration of the controller of the refrigerator according to the H.M. cycle of the present invention will be described with reference to FIG. The input side of the control unit 35 has a door switch 36, a refrigerator compartment temperature sensor 37, a freezer compartment temperature sensor 38, an outside air temperature sensor 39, a first cooler surface temperature sensor 40 and a second cooler surface temperature.

이러한 제어부(35)의 제어방식은 냉동실온도센서(38)에 의해 검지된 냉동실의 온도(TF)와 식품의 냉동보관을 위해 적절한 온도로 미리 정해진 냉동실설정온도(TFS), 그리고 냉장실온도센서(37)에 의해 감지된 냉동실의 온도(TR)와 식품의 냉장보관을 위해 적절한 온도로 미리 정해진 냉동실설정온도(TRS)를 비교함으로써 이루어진다. 본 명세서에서 설정온도라 함은 냉장고 고유의 특성을 유지할 수 있는 고내의 온도대역을 말하는 것으로, 냉동실설정온도(TFS)는 전술한 바와 같이 식품의 냉동보관을 위해 적절한 온도로 미리 정해진 온도로서 -15℃~-21℃의 범위이다. 즉 냉동실설정온도(TFS)는 이러한 범위내에서, 사용자의 선택에 따라 미리 정해진 -21℃(냉동강), -18℃(냉동중), -15℃(냉동약)의 어느 하나로 정해진다. 또한 냉동실설정온도(TRS)는 전술한 바와 같이 식품의 냉장보관을 위해 적절한 온도로 미리 정해진 온도로서 6℃~-1℃의 범위이다. 즉 냉동실설정온도(TRS)는 이러한 범위내에서, 사용자의 선택에 따라 미리 정해진 -1℃(냉장강), 3℃(냉장중), 6℃(냉장약)의 어느 하나로 정해진다.The control unit 35 controlled the temperature of the detecting freezing by the freezing compartment temperature sensor 38 in the (T F) and the freezer compartment pre-set at a suitable temperature for the cold storage of food set temperature (T FS), and the fresh food compartment temperature sensor This is accomplished by comparing the temperature T R of the freezer compartment detected by (37) with a predetermined freezer compartment set temperature (T RS ) to an appropriate temperature for cold storage of food. In the present specification, the set temperature refers to a temperature range within the refrigerator capable of maintaining inherent characteristics of the refrigerator, and the freezer setting temperature (T FS ) is a predetermined temperature at a temperature suitable for freezing storage of food as described above. It is the range of 15 degreeC--21 degreeC. That is, the freezer compartment set temperature T FS is set within any one of -21 ° C (freezing steel), -18 ° C (freezing), and -15 ° C (frozen medicine) predetermined according to the user's selection.

이하에서는 본 발명에 따른 냉장고 제어방법의 구체적인 실시예를 도면을 참조하여 설명한다.Hereinafter, a specific embodiment of a refrigerator control method according to the present invention will be described with reference to the drawings.
먼저, 냉동실온도(TF)와 냉동실설정온도(TFS), 냉장실온도(TR)와 냉장실설정온도(TRS)를 비교한다(251). 단계251에서 냉동실온도(TF)가 냉동실설정온도(TFS)보다 높거나 냉장실온도(TR)가 냉장실설정온도(TRS)보다 높은 경우에 냉장실온도(TS)와 냉장실설정온도(TRS)를 비교한다(단계252), 단계252에서 냉장실온도(TR)가 냉장실설정온도(TRS)보다 높은 경우에 냉동실온도(TF)와 냉동실설정온도(TFS)를 비교하여(단계253), 냉동실온도(TF)가 냉동실설정온도(TFS)보다 높은 경우에는 압축기와 냉장실팬 및 냉동실팬을 온시켜 양실을 동시냉각하고(단계254), 냉동실온도(TF)가 냉동실설정온도(TFS) 이하인 경우에는 압축기와 냉장실팬을 온시키고 냉동실팬을 오프시켜 냉장실만 냉각시킨다(단계255).First, the freezer compartment temperature T F and the freezer compartment set temperature T FS , the refrigerator compartment temperature T R , and the refrigerator compartment set temperature T RS are compared (251). In step 251 the refrigerator compartment temperature T S and the refrigerator compartment set temperature T T when the freezer temperature T F is higher than the freezer preset temperature T FS or the refrigerator compartment temperature T R is higher than the refrigerator compartment set temperature T RS . RS is compared (step 252), and in step 252, when the refrigerator compartment temperature T R is higher than the refrigerator compartment set temperature T RS , the freezer compartment temperature T F and the freezer compartment set temperature T FS are compared (step 252). 253) If the freezer temperature T F is higher than the freezer set temperature T FS , the compressor, the refrigerating fan and the freezer fan are turned on to simultaneously cool both chambers (step 254), and the freezer temperature T F is set to the freezer compartment. If the temperature is below T FS , the compressor and the refrigerator compartment fan are turned on and the freezer compartment fan is turned off to cool only the refrigerator compartment (step 255).
단계252에서 냉장실온도(TR)가 냉장실설정온도(TRS) 이하인 경우에는 냉동실온도(TF)와 냉장실설정온도(TFS)를 비교하여(단계256), 냉동실온도(TF)가 냉동실설정온도(TFS) 이하인 경우에는 단계251로 되돌아가고, 냉동실온도(TF)가 냉동실설정온도(TFS)보다 높은 경우에는 압축기와 냉동실팬을 온시키고 냉장실팬을 오프시켜 냉동실을 냉각시킨다(단계257). 즉, 냉동실이 불만족이거나 냉장실 불만족이거나 어느 경우에든 압축기는 운전되되 각 실의 상태에 따라 압축기와 함께 냉동실팬이 운전될 것인지 냉장실팬이 운전될 것인지가 판단된다. 단계254, 255, 257 이후에는 최초의 단계로 되돌아간다.If the refrigerator compartment temperature T R is equal to or lower than the refrigerator compartment set temperature T RS in step 252, the freezer compartment temperature T F is compared with the refrigerator compartment set temperature T FS (step 256), and the freezer compartment temperature T F is the freezer compartment. If the temperature is lower than the set temperature (T FS ), the process returns to step 251. If the freezer temperature (T F ) is higher than the freezer temperature (T FS ), the compressor and the freezer fan are turned on and the refrigerator compartment fan is turned off to cool the freezer ( Step 257). In other words, whether the refrigerator is unsatisfactory or the refrigerator is unsatisfactory, the compressor is operated, but it is determined whether the refrigerator compartment fan or the refrigerator compartment fan is operated with the compressor according to the state of each chamber. After steps 254, 255 and 257, the process returns to the first step.
한편, 단계251에서 냉장실온도(TR)가 냉장실설정온도(TRS) 이하이고, 냉동실온도(TF)가 냉동실설정온도(TFS) 이하인 경우에는 압축기, 냉장실팬과 냉동실팬을 오프시킨다(단계258). 단계258에 이어서 제1냉각표면온도(TES)가 0℃보다 높은가를 비교하여(단계259). 단계259에서 제1냉각기표면온도(TES)가 0℃ 이하인 경우에는 압축기와 냉동실팬을 오프시키고 냉장실팬만을 온시켜(단계260) 냉장실증발기인 제1냉각기의 제상을 수행한다. 단계260 이후에는 계속해서 단계259을 수행하고, 단계259에서 제1냉각기표면오도(TES)가 0℃보다 높은 경우에는 최초의 단계251로 되돌아간다.On the other hand, if the refrigerator compartment temperature (T R ) is below the refrigerator compartment set temperature (T RS ) and the freezer compartment temperature (T F ) is below the freezer compartment set temperature (T FS ) in step 251, the compressor, the refrigerator compartment fan, and the freezer compartment fan are turned off ( Step 258). Step 258 is then followed by comparing whether the first cooling surface temperature T ES is higher than 0 ° C. (step 259). When the first cooler surface temperature T ES is 0 ° C. or lower in step 259, the compressor and the freezer compartment fan are turned off and only the refrigerator compartment fan is turned on (step 260) to perform defrosting of the first cooler, which is a refrigerator compartment evaporator. After step 260, step 259 is continued, and when step 159, the first cooler surface temperature T ES is higher than 0 ° C, the process returns to the first step 251.
이와 같이 본 실시예에서 압축기는 냉동실의 상태뿐만이 아니라 냉장실의 상태에 의해서도 운전될 수 있는데, 특히 냉동실과 무관하게 냉장실의 온도가 냉장실설정온도보다 높은 상태에 있는 경우에도 압축기는 온된다. 이러한 상황은 정상적인 운전을 수행하다가 압축기가 오프된 상태에서 냉장실의 사용빈도 과도로 냉장실이 설정온도 이상의 고온으로 되었을 경우 발생한다. 따라서 각 실은 다른 실의 상태와 상관없이 냉각이 될 필요가 있으면 언제든지 완전히 독립적으로 냉각되므로 각 실의 설정온도를 가장 충실하게 유지시킬 수 있는 장점이 있다.Thus, in the present embodiment, the compressor can be operated not only by the state of the freezer compartment but also by the state of the refrigerator compartment. In particular, even when the temperature of the refrigerator compartment is higher than the refrigerator compartment set temperature regardless of the freezer compartment, the compressor is turned on. This situation occurs when the refrigerating compartment is at a high temperature above the set temperature due to excessive use of the refrigerating compartment while the compressor is turned off during normal operation. Therefore, each chamber is cooled completely independently at any time if it needs to be cooled regardless of the condition of other chambers, so that the set temperature of each chamber can be maintained most faithfully.
이상에서 상세히 설명한 바와 같이, 본 발명에서는 냉동실과 냉장실에 별도의 냉각시스템(냉각기와 냉각팬)을 설치하고 이들을 독립적으로 제어함과 동시에 냉장고 외부의 온도에 따라 각 실의 제어방법을 달리함으로써 각 실의 냉각속도를 극대화하고 효율적으로 제어할 수 있다.As described in detail above, in the present invention, by installing separate cooling systems (coolers and cooling fans) in the freezer compartment and the refrigerating compartment and controlling them independently, the control method of each compartment is changed according to the temperature of the outside of the refrigerator. It can maximize the cooling speed and control efficiently.
