본 발명은 2개의 증발기가 구비된 냉장고에 관한 것으로서, 더욱 상세하게는 냉동실용 증발기의 제상주기가 되면 냉동실과 냉장실의 실내온도를 제어부에 기설정된 하한치 온도까지 낮춘 후에 냉동실용 증발기의 제상운전을 실시하도록 하는 2개의 증발기가 구비된 냉장고의 운전 방법에 관한 것이다.The present invention relates to a refrigerator provided with two evaporators, and more particularly, when the defrost cycle of the freezer compartment evaporator is performed, the defrosting operation of the freezer compartment evaporator is performed after lowering the room temperature of the freezer compartment and the refrigerating compartment to a lower limit temperature preset in the control unit. It relates to a method of operating a refrigerator provided with two evaporators.

이하, 종래의 냉장고 시스템에 대해 참조도면 도 1을 참조하여 설명하면 다음과 같다.Hereinafter, a conventional refrigerator system will be described with reference to FIG. 1.

도 1은 종래 2개의 증발기가 구비된 냉장고 시스템을 나타낸 개략도로서 이를 참조하면, 종래의 냉장고는 냉동실과 냉장실로 이루어지는데, 상기 냉동실의 일측에는 냉동실용 증발기(6)가 설치되고, 상기 냉장실의 일측에는 냉장실용 증발기(7)가 설치된다.1 is a schematic view showing a conventional refrigerator system having two evaporators. Referring to this, a conventional refrigerator includes a freezing compartment and a refrigerating compartment. One side of the freezing compartment is provided with a freezing compartment evaporator 6 and one side of the refrigerating compartment. The refrigerator compartment evaporator 7 is installed.

상기 냉동실용 증발기(6) 근처에는 냉동팬(6a)과 히터(6b)가 설치되고, 상기 냉장실용 증발기(7) 근처에는 냉장팬(7a)과 히터(7b)가 설치된다.A freezing fan 6a and a heater 6b are installed near the freezer evaporator 6, and a refrigerating fan 7a and a heater 7b are installed near the freezer evaporator 7.

또한, 상기 냉동실과 냉장실의 외부에는 압축기(1), 응축기(2), 삼방밸브(3) 및 각 팽창장치(4,5)가 설치된다.In addition, the compressor (1), the condenser (2), the three-way valve (3) and each expansion device (4, 5) is provided outside the freezing chamber and the refrigerating chamber.

한편, 상기 냉동실과 냉장실에는 각각 온도센서(미도시)가 설치되는데, 상기 온도센서는 냉동실과 냉장실의 실내온도를 감지하여 그 정보를 제어부(미도시)에 제공한다.Meanwhile, a temperature sensor (not shown) is installed in each of the freezing compartment and the refrigerating compartment, and the temperature sensor senses an indoor temperature of the freezing compartment and the refrigerating compartment and provides the information to the controller (not shown).

상기 냉동실과 냉장실의 실내온도가 일정한 범위 내에서 유지되도록 하기 위해 상기 제어부에는 냉동실과 냉장실에 대한 상한치 온도 및 하한치 온도가 각각 설정되어 있는데, 이러한 상한치 온도와 하한치 온도 사이의 범위를 이하에서는 설정온도 범위라고 한다.In order to maintain the indoor temperature of the freezer compartment and the refrigerating compartment within a predetermined range, the control unit is set to the upper limit temperature and the lower limit temperature for the freezer compartment and the refrigerating compartment, respectively, the range between the upper limit temperature and the lower limit temperature in the following set temperature range It is called.

이와 같은 2개의 증발기가 구비된 냉장고에 대해 그 작용을 설명하면 다음과 같다.The operation of the refrigerator having two evaporators as described above is as follows.

상기 압축기(1)에서 압축된 고온고압의 냉매는 응축기(2)에 압송되고, 상기응축기(2)에서 응축된 냉매는 삼방밸브(3)에 보내진다.The refrigerant having a high temperature and high pressure compressed by the compressor 1 is sent to the condenser 2, and the refrigerant condensed in the condenser 2 is sent to the three-way valve 3.

이때, 상기 냉동실 및 냉장실의 내부온도가 설정온도 범위를 만족시키지 못하면, 상기 삼방밸브(3)는 R/F 사이클 모드로 개방된다.At this time, if the internal temperature of the freezer compartment and the refrigerating compartment does not satisfy the set temperature range, the three-way valve 3 is opened in the R / F cycle mode.

삼방밸브(3)가 R/F 사이클 모드로 개방되면, 상기 냉장고는 압축기(1) 및 응축기(2)를 통과한 냉매를 삼방밸브(3), 제 2 팽창장치(5), 냉장실용 증발기(7) 및 냉동실용 증발기(6)를 순차적으로 유동시키는 R/F 사이클을 수행한다.When the three-way valve 3 is opened in the R / F cycle mode, the refrigerator passes the refrigerant passing through the compressor 1 and the condenser 2 to the three-way valve 3, the second expansion device 5, and the refrigerating chamber evaporator ( 7) and the R / F cycle to sequentially flow the freezer evaporator (6).

또한, 상기 냉장실의 내부온도가 설정온도 범위를 만족시키면, 상기 삼방밸브(3)는 F 사이클 모드로 개방된다.In addition, when the internal temperature of the refrigerating chamber satisfies the set temperature range, the three-way valve 3 is opened in the F cycle mode.

이에 따라, 상기 냉장고는 압축기(1) 및 응축기(2)를 통과한 냉매를 삼방밸브(3), 제 1 팽창장치(4)와 냉동실용 증발기(6)를 따라 순차적으로 유동시키는 F 사이클을 수행한다.Accordingly, the refrigerator performs an F cycle of sequentially flowing the refrigerant passing through the compressor 1 and the condenser 2 along the three-way valve 3, the first expansion device 4, and the freezing chamber evaporator 6. do.

이상에서와 같이, 냉장고가 R/F 사이클이나 F 사이클로 장시간 동안 운전되면 각 증발기(6,7)에는 서리가 결빙되게 된다.As described above, when the refrigerator is operated for a long time in an R / F cycle or an F cycle, frost is frozen in each of the evaporators 6 and 7.

이러한 서리는 증발기(6,7)와 공기가 열접촉하는 것을 방해하여 증발기(6,7)의 열교환 효율을 상당히 저하시키므로, 상기 증발기(6,7)에 결빙된 서리를 제거시키는 제상운전을 실시한다.This frost prevents the heat contact between the evaporators 6 and 7 in thermal contact and thus considerably lowers the heat exchange efficiency of the evaporators 6 and 7, and thus performs a defrosting operation to remove frost frozen in the evaporators 6 and 7. do.

이러한 제상운전을 위해, 상기 제어부에는 각 증발기(6,7)가 주기적으로 제상운전될 수 있도록 각 증발기(6,7)에 대응되는 제상주기를 미리 설정해둔다.For this defrosting operation, the control unit presets a defrosting period corresponding to each of the evaporators 6 and 7 so that the evaporators 6 and 7 can be defrosted periodically.

상기 제어부는 각 증발기(6,7) 일측에 설치된 팬(6a,7a)의 운전시간을 적산(積算)하여 상기 팬의 적산된 운전시간이 제어부에 미리 설정된 제상주기에 도달되면, 상기 증발기(6,7) 근처에 설치된 히터(6b,7b)를 가동하여 증발기(6,7)에 결빙된 서리를 제상시킨다.The control unit accumulates the operating time of the fans 6a and 7a installed at one side of each evaporator 6 and 7, and when the accumulated operating time of the fan reaches a defrosting period set in advance in the control unit, the evaporator 6 The heaters 6b and 7b installed near to 7 are operated to defrost frost frozen in the evaporators 6 and 7.

또한, 상기 제어부는 압축기(1)의 운전시간을 적산하여 상기 압축기(1)의 적산된 운전시간이 제어부에 미리 설정된 제상주기에 도달되면, 상기 증발기(6,7)에 결빙된 서리를 제상시킬 수도 있음은 이해 가능하다.In addition, the control unit accumulates the operating time of the compressor 1 and when the accumulated operating time of the compressor 1 reaches a defrosting period set in advance in the control unit, defrosting the frost frozen in the evaporator (6, 7). It is understandable.

이어, 상기 증발기(6,7)의 제상운전이 완료되고 일정한 휴지기를 경과한 후에 상기 냉장고의 냉각운전을 재시작한다.Subsequently, after the defrosting operation of the evaporators 6 and 7 is completed and a certain rest period has elapsed, the cooling operation of the refrigerator is restarted.

그러나, 상기 냉장실 및 냉동실의 실내온도가 각각 설정온도 범위의 상한치 온도에 가까운 상태일 때에 상기 냉동실용 증발기(6)의 제상운전이 실시되면, 상기 냉동실용 증발기(6)의 제상운전이 시작되는 시간부터 일정한 휴지기를 거쳐 냉장고의 냉각운전이 재시작될 때까지 냉장실 및 냉동실의 실내온도가 상당히 올라가는 문제점이 발생된다.However, if the defrosting operation of the freezer compartment evaporator 6 is performed when the indoor temperatures of the refrigerating compartment and the freezing compartment are respectively close to the upper limit temperatures of the set temperature range, a time at which the defrosting operation of the freezer compartment evaporator 6 starts. From a certain period of time until the cooling operation of the refrigerator is restarted, there is a problem that the room temperature of the refrigerating compartment and the freezing compartment considerably rises.

이는 외부공기와 냉장고 시스템이 상호 열교환되기 때문이다.This is because the outside air and the refrigerator system are mutually heat exchanged.

이에 따라, 상기 냉동실 및 냉장실의 실내온도를 다시 설정온도 범위 내로 낮추는 데에 보다 많은 전력이 소모된다.Accordingly, more power is consumed to lower the room temperature of the freezer compartment and the refrigerating compartment back to the set temperature range.

또한, 최근의 기술동향으로 볼 때, 상기 냉동실 및 냉장실의 실내온도를 일정하게 유지시킴으로써 김치나 육고기 같은 음식물의 고유의 맛을 유지시키는 것이 관건이라 할 수 있으므로, 상기와 같이 냉동실 및 냉장실의 실내온도를 가능한 한 설정온도 범위로 유지시키는 것이 요구된다.In addition, in view of recent technical trends, maintaining the intrinsic taste of foods such as kimchi and meat by keeping the indoor temperature of the freezer and refrigerator compartment constant, the room temperature of the freezer and refrigerator compartment as described above. It is required to keep the temperature in the set temperature range as much as possible.

상기한 제반 문제점을 해결하기 위해, 본 발명은 냉동실용 증발기가 제상운전 될 때에 냉장실의 내부온도가 설정온도 범위 내에서 운전되도록 하는 것을 그 목적으로 한다.In order to solve the above-mentioned problems, an object of the present invention is to allow the internal temperature of the refrigerating compartment to be operated within a set temperature range when the freezer evaporator is defrosted.

상기한 목적을 달성하기 위해, 본 발명은 냉동실용 증발기와 냉장실용 증발기에 각각 대응되도록 제어부에 미리 설정된 제상주기마다 각 증발기의 제상운전을 실시하는 냉장고에 있어서, 상기 냉동실용 증발기의 제상시점이 되면 상기 냉동실 및 냉장실의 실내온도를 제어부에 미리 설정된 설정온도 범위의 하한치 온도까지 각각 낮춘 후에 압축기의 운전을 정지시키고 히터를 가동시킴으로써 상기 냉동실용 증발기의 제상운전을 실시하는 것을 특징으로 하는 2개의 증발기가 구비된 냉장고의 운전 방법을 제공한다.In order to achieve the above object, the present invention is a refrigerator for performing the defrosting operation of each evaporator for each defrost cycle set in advance in the control unit so as to correspond to the freezer evaporator and the refrigerating compartment evaporator, respectively, when the defrost point of the freezer compartment evaporator The two evaporators for defrosting the freezer compartment evaporator are performed by lowering the room temperature of the freezer compartment and the refrigerating compartment to the lower limit temperature of the preset temperature range set by the controller, and then stopping the operation of the compressor and operating the heater. It provides a method of operating the provided refrigerator.

본 발명에 따른 냉장고의 운전 방법은 종래와 거의 유사하므로, 종래와 동일한 부분에 대해서는 동일한 도번을 부여하고 동일한 구조에 관해서는 그 설명을 생략한다.Since the operation method of the refrigerator according to the present invention is almost similar to the prior art, the same parts are assigned to the same parts as in the prior art, and the description of the same structure is omitted.

이하, 본 발명에 따른 냉장고의 운전 방법에 관해 참조도면 도 2를 참조하여 설명하면 다음과 같다.Hereinafter, a method of operating a refrigerator according to the present invention will be described with reference to FIG. 2.

도 2는 본 발명에 따른 냉장고의 운전 방법을 나타낸 흐름도로서 이를 참조하면, 냉장고가 R/F 사이클이나 F 사이클로 장시간 동안 냉각 운전되면 각 증발기(6,7)에는 서리가 결빙되게 된다.2 is a flowchart illustrating a method of operating a refrigerator according to the present invention. Referring to this, when the refrigerator is cooled for a long time by an R / F cycle or an F cycle, frost is frozen in each of the evaporators 6 and 7.

상기 각 증발기(6,7)에 서리가 결빙되면 증발기(6,7)의 열교환 효율이 상당히 저하되므로 상기 각 증발기(6,7)를 제상운전시켜야 한다.If the frost on each evaporator (6,7) is frozen, the heat exchange efficiency of the evaporator (6,7) is considerably lowered, so each of the evaporators (6,7) must be defrosted.

이를 위해, 상기 각 증발기(6,7)가 주기적으로 제상 운전될 수 있도록 제어부에는 각 증발기(6,7)에 대응되는 제상주기를 미리 설정해둔다.To this end, the defrosting period corresponding to each of the evaporators 6 and 7 is set in advance in the control unit so that the respective evaporators 6 and 7 can be defrosted periodically.

한편, 상기 각 증발기(6,7)는 제어부에 설정된 제상주기가 각각 다르게 설정되므로 상기 각 증발기(6,7)가 독립적으로 제상운전되는데, 이하 냉장실용 증발기(7)와 냉동실용 증발기(6)의 제상운전을 나누어서 설명하기로 한다.On the other hand, each of the evaporator (6,7) because the defrosting period set in the control unit is set differently, each of the evaporator (6,7) is independently defrosting operation, the refrigerating chamber evaporator (7) and freezer evaporator (6) The defrosting operation will be described separately.

먼저, 상기 냉장실용 증발기(7)의 제상운전에 대해 설명하면 다음과 같다.First, the defrosting operation of the refrigerating chamber evaporator 7 is as follows.

상기 제어부는 냉장실용 증발기(7) 일측에 설치된 냉장팬(7a)의 운전시간을 적산한다.The control unit integrates the operation time of the refrigerating fan 7a installed at one side of the refrigerating chamber evaporator 7.

상기 냉장팬(7a)의 적산된 운전시간이 제어부에 미리 설정된 제상주기에 도달되면, 상기 냉장실용 증발기(7) 근처에 설치된 히터(7b)를 가동하여 냉장실용 증발기(7)의 제상운전을 실시한다.When the accumulated operating time of the refrigerating fan 7a reaches a predetermined defrost cycle in the control unit, the heater 7b installed near the refrigerating compartment evaporator 7 is operated to perform defrosting operation of the refrigerating compartment evaporator 7. do.

이와 같이, 상기 냉장고가 F 사이클로 운전되는 상태에서 냉장실용 증발기(7)를 제상운전할 경우, 상기 냉장실용 증발기(7)에는 냉매가 공급되지 않는 상태이므로 압축기(1)의 운전을 멈출 필요 없이 냉장고를 F 사이클로 운전시키면서 냉장실용 증발기(7)의 제상운전을 실시한다.As described above, when the refrigerator evaporator 7 is defrosted while the refrigerator is operated in an F cycle, since the refrigerant is not supplied to the refrigerator compartment evaporator 7, the refrigerator is not required to stop the operation of the compressor 1. The defrosting operation of the refrigerator compartment evaporator 7 is performed while operating in F cycle.

또한, 압축기(1)의 운전을 정지시킨 후에 냉장실용 증발기(7)의 제상운전을 실시할 수도 있음은 이해 가능하다.It is also understood that the defrosting operation of the refrigerating compartment evaporator 7 may be performed after the operation of the compressor 1 is stopped.

다음으로, 상기 냉동실용 증발기(6)의 제상운전에 대해 설명하면 다음과 같다.Next, the defrosting operation of the freezer compartment evaporator 6 will be described.

상기 제어부는 냉동실용 증발기(6)의 일측에 설치된 냉동팬(6a)의 운전시간을 적산한다.The control unit integrates the operation time of the freezing fan 6a installed at one side of the freezing chamber evaporator 6.

상기 냉동팬(6a)의 적산된 운전시간이 제어부에 미리 설정된 제상주기에 도달되면, 상기 냉동실 및 냉장실의 실내온도를 제어부에 미리 설정된 설정온도 범위의 하한치 온도까지 각각 낮춘다.When the accumulated operating time of the refrigerating fan 6a reaches a defrosting period preset in the controller, the indoor temperatures of the freezer compartment and the refrigerating compartment are respectively lowered to the lower limit temperature of the preset temperature range set in the controller.

이상에서와 같이, 상기 냉동실 및 냉장실의 실내온도를 하한치 온도까지 낮춘 후에 상기 압축기(1)의 운전을 정지시키고 냉동실용 증발기(6) 근처에 설치된 히터(6b)를 가동하여 냉동실용 증발기(6)에 결빙된 서리를 제거시킨다.As described above, after the indoor temperature of the freezer compartment and the refrigerating compartment is lowered to the lower limit temperature, the operation of the compressor 1 is stopped and the heater 6b installed near the freezer compartment evaporator 6 is operated to freeze the evaporator 6. Remove frost on the ice.

이때, 상기 냉장고가 F 사이클이나 R/F 사이클 중에서 어느 사이클로 운전되더라도 유동 냉매는 냉동실용 증발기(6)를 통과하므로, 상기 냉동실용 증발기(6)를 제상운전시킬 때는 압축기(1)의 운전을 정지시켜야 한다.At this time, the refrigerant flows through the freezer compartment evaporator 6 even if the refrigerator is operated in any of cycles F or R / F, and thus, the compressor 1 is stopped when the freezer compartment evaporator 6 is defrosted. You have to.

상기와 같이 냉동실 및 냉장실의 실내온도를 설정온도 범위의 하한치까지 낮춘 후에 냉동실용 증발기(6)의 제상운전을 실시하면, 상기 냉동실용 증발기(6)의 제상운전이 시작될 때부터 냉각운전이 재시작될 때까지 상기 냉동실 및 냉장실이 외기와 열교환됨에 의해 설정온도 범위의 상한치 온도 이상으로 상승되는 것을 방지할 수 있다.If the defrosting operation of the freezer compartment evaporator 6 is performed after lowering the indoor temperatures of the freezer compartment and the refrigerating compartment to the lower limit of the set temperature range, the cooling operation is restarted from the start of the defrosting operation of the freezer compartment evaporator 6. Until the freezer compartment and the refrigerating compartment are heat exchanged with the outside air, it is possible to prevent the freezing compartment and the refrigerating compartment from rising above the upper limit temperature of the set temperature range.

이에 따라, 상기 냉동실 및 냉장실의 실내온도를 설정온도 범위에서 보다 안정적으로 유지시킬 수 있으므로 냉장고의 고급화에 기여할 수 있다.Accordingly, the indoor temperature of the freezer compartment and the refrigerating compartment can be more stably maintained within the set temperature range, thereby contributing to the enhancement of the refrigerator.

또한, 냉동실 및 냉장실에 보관되는 육류 및 김치 등과 같은 음식물의 고유한 맛을 보다 오랫동안 유지시킬 수 있다.In addition, the inherent taste of foods such as meat and kimchi stored in the freezer and the refrigerating compartment can be maintained for a longer time.

이상에서와 같이, 본 발명은 냉장실용 증발기의 제상운전이 실시되는 중에 냉동실과 냉장실의 실내온도가 설정온도 범위의 상한치 온도까지 상승되는 것을 방지하여 상기 냉동실 및 냉장실의 실내 온도의 변동폭을 감소시킬 수 있다.As described above, the present invention can prevent the room temperature of the freezer compartment and the refrigerating compartment from being raised to the upper limit temperature of the set temperature range while the defrosting operation of the refrigerating compartment evaporator is performed, thereby reducing the fluctuation range of the room temperature of the freezer compartment and the refrigerating compartment. have.
