Description

2개의 증발기가 구비된 냉장고의 냉장팬을 이용한 제상 방법{defrosting method in the refrigerator using fan}Defrosting method in the refrigerator using fan

본 발명은 2개의 증발기가 구비된 냉장고에 관한 것으로서, 더욱 상세하게는 냉동실과 냉장실 및 저장실의 실내온도가 제어부에 저장된 설정온도 범위를 만족시킴에 의해 압축기의 운전이 정지된 상태에서, 상기 냉장실용 증발기의 냉장팬을 회전시키도록 하여 냉장실용 증발기에 결빙된 서리를 제거하는 2개의 증발기가 구비된 냉장고의 냉장팬을 이용한 제상방법에 관한 것이다.The present invention relates to a refrigerator provided with two evaporators, and more particularly, the refrigerator compartment for the refrigerator compartment in a state in which the operation of the compressor is stopped by satisfying the set temperature range stored in the control unit in the freezer compartment, the refrigerator compartment and the storage compartment. It relates to a defrosting method using a refrigerator fan of a refrigerator provided with two evaporators to rotate the refrigerator fan of the evaporator to remove frost frozen in the refrigerator compartment evaporator.

일반적인 냉장고는 냉동실과 냉장실로 이루어지는데, 상기 냉동실에 설치된 증발기는 냉동실과 냉장실의 내부온도를 낮추어 준다.A general refrigerator consists of a freezer compartment and a refrigerating compartment. The evaporator installed in the freezer compartment lowers the internal temperatures of the freezer compartment and the refrigerating compartment.

이와 같이 냉동실과 냉장실의 내부온도를 낮추기 위해, 상기 냉장고는 압축기에서 압축된 고온고압 냉매를 응축기 및 팽창밸브를 통해 증발기에 보내는 냉각 사이클로 운전된다.Thus, in order to lower the internal temperature of the freezer compartment and the refrigerating compartment, the refrigerator is operated in a cooling cycle of sending the high temperature and high pressure refrigerant compressed by the compressor to the evaporator through the condenser and the expansion valve.

상기 증발기에 냉매가 도달되면 증발기의 일측에 설치된 팬을 회전시키고, 상기 팬의 회전에 의해 증발기의 냉기가 냉동실과 냉장실에 공급되도록 하여 냉동실과 냉장실의 저온상태를 유지시킨다.When the refrigerant reaches the evaporator, a fan installed on one side of the evaporator is rotated, and the cold air of the evaporator is supplied to the freezing compartment and the refrigerating compartment by the rotation of the fan to maintain the low temperature state of the freezing compartment and the refrigerating compartment.

그러나, 상기 냉장고의 냉각운전이 장시간 동안 계속되면 상기 증발기에 많은 양의 서리가 결빙되어 증발기의 열교환 효율을 상당히 저감시킨다.However, if the cooling operation of the refrigerator is continued for a long time, a large amount of frost is frozen in the evaporator, which considerably reduces the heat exchange efficiency of the evaporator.

이와 같이 결빙된 서리를 제거하기 위해 일정한 주기마다 냉장고의 제상을 실시하는데, 상기 제상은 압축기를 정지시킨 후에 증발기 근처에 설치된 히터를 가동시킴으로써 증발기에 결빙된 서리를 제거하는 것이다.The defrost of the refrigerator is performed at regular intervals to remove the frozen frost. The defrost is to remove frost frozen in the evaporator by stopping the compressor and then operating a heater installed near the evaporator.

상기와 같은 제상이 완료되면 소정의 휴지기를 거친 후에 다시 상기 압축기를 가동시켜 냉매를 증발기에 유동시키는 냉각운전을 재시작한다.After the defrosting is completed, the cooling operation for restarting the compressor by flowing the refrigerant to the evaporator after restarting the compressor is performed.

이상에서와 같이, 제상운전을 수행하면서 냉장고 내부의 온도를 높였다가 다시 냉각운전을 수행하면서 냉장고 내부의 온도를 낮추는 경우 많은 열손실이 발생된다.As described above, when the temperature inside the refrigerator is increased while the defrosting operation is performed and the temperature inside the refrigerator is lowered while performing the cooling operation again, many heat losses are generated.

따라서, 상기 증발기에 결빙된 서리를 제거하기 위해서는 일정한 주기마다 제상을 해야 하지만, 상기 냉장고의 열손실을 최소화시키기 위해서는 가능한 한 히터를 이용한 제상의 주기를 연장시키는 것이 요구된다.Therefore, although defrosting is required every certain period to remove frost frozen in the evaporator, it is required to extend the defrosting period using a heater as much as possible in order to minimize the heat loss of the refrigerator.

상기한 문제점을 해결하기 위해, 본 발명은 냉동실과 냉장실 및 저장실의 실내온도가 제어부에 저장된 설정온도 범위를 만족시킴에 의해 압축기의 운전이 정지될 때에 냉장실용 증발기의 냉장팬을 가동시킴으로써 냉장실용 증발기에 결빙된 서리를 제거하도록 하는 것을 그 목적으로 한다.In order to solve the above problems, the present invention provides a refrigerator compartment evaporator by operating a refrigerating fan of the refrigerator compartment evaporator when the operation of the compressor is stopped by satisfying the set temperature range stored in the controller of the freezer compartment, the refrigerator compartment and the storage compartment. The purpose is to remove frost frozen in the ice.

이를 위해, 본 발명은 냉장고를 이루는 냉동실과 냉장실 및 저장실의 실내온도가 제어부에 저장된 설정온도 범위를 만족시키는지 확인하는 단계; 상기 확인 결과 각 실내온도가 설정온도 범위를 만족할 경우 압축기의 운전을 정지하는 단계; 상기 냉장실용 증발기의 온도를 측정하는 단계; 그리고, 상기 측정된 냉장실용 증발기의 온도가 얼음이 녹는 온도 이상이 될 경우 냉장실용 증발기의 일측에 설치된 냉장팬을 회전시켜 냉장실용 증발기에 결빙된 서리를 녹이도록 하는 단계:가 포함되어 제어됨을 특징으로 하는 2개의 증발기가 구비된 냉장고의 냉장팬을 이용한 제상 방법에 관한 것이다.To this end, the present invention comprises the steps of checking whether the indoor temperature of the freezer compartment and the refrigerating compartment and the storage compartment constituting the refrigerator satisfies the set temperature range stored in the control unit; Stopping operation of the compressor when each indoor temperature satisfies the set temperature range as a result of the checking; Measuring the temperature of the refrigerating chamber evaporator; And, if the measured temperature of the refrigerating chamber evaporator is more than the melting temperature of the ice melting the frost frozen in the refrigerating chamber evaporator by rotating the refrigerating fan installed on one side of the refrigerating chamber evaporator: characterized in that it is controlled It relates to a defrosting method using a refrigeration fan of a refrigerator provided with two evaporators.

이하, 본 발명에 따른 제상 방법에 대해 참조도면 도 1을 참조하여 설명하면 다음과 같다.Hereinafter, the defrosting method according to the present invention will be described with reference to FIG. 1.

도 1은 냉장고의 구성 및 냉매 사이클을 간략하게 나타낸 개략도로서 이를 참조하면, 상기 냉장고에는 냉동실(6), 냉장실(7) 및 저장실(8)이 구비되는데, 상기 냉동실(6)과 냉장실(7)의 일측에는 각각 증발기(6a,7a)와 팬(6b,7b)이 설치되고, 상기 냉장실(7)과 저장실(8)에는 각각 댐퍼(9,9a)가 설치된다.FIG. 1 is a schematic view illustrating a configuration and a refrigerant cycle of a refrigerator. Referring to the refrigerator, the refrigerator includes a freezing compartment 6, a refrigerating compartment 7, and a storage compartment 8, the freezing compartment 6 and a refrigerating compartment 7. Evaporators 6a and 7a and fans 6b and 7b are respectively installed at one side of the dampers, and dampers 9 and 9a are respectively installed in the refrigerating chamber 7 and the storage chamber 8.

또한, 상기 냉동실(6)과 냉장실(7)의 외부에는 압축기(1), 응축기(2), 삼방밸브(3) 및 팽창장치(4,5)가 설치된다.In addition, the compressor (1), the condenser (2), the three-way valve (3) and the expansion devices (4, 5) are provided outside the freezing chamber (6) and the refrigerating chamber (7).

한편, 상기 냉동실과 냉장실 및 저장실에는 각각 온도센서(10,10a,10b)가 설치되며, 상기 온도센서는 냉동실과 냉장실 및 저장실의 실내온도를 감지하여 감지된 정보를 제어부(미도시)에 전달한다.Meanwhile, temperature sensors 10, 10a, and 10b are installed in the freezing compartment, the refrigerating compartment, and the storage compartment, respectively, and the temperature sensor senses the room temperature of the freezing compartment, the refrigerating compartment, and the storage compartment, and transmits the detected information to a controller (not shown). .

상기 제어부에는 냉동실(6)과 냉장실(7) 및 저장실(8)이 일정한 범위의 온도를 유지할 수 있도록 각각 대응되는 상한치 온도와 하한치 온도가 설정되데, 이러한 상한치 온도와 하한치 온도 사이의 범위를 이하에서는 냉동실(6)과 냉장실(7) 및 저장실(8)의 설정온도 범위로 하기로 한다.The control unit is set to the upper and lower limit temperature corresponding to each of the freezer compartment 6, the refrigerating compartment 7 and the storage compartment 8 to maintain a constant range of temperature, the range between the upper limit temperature and the lower limit temperature will be described below. The freezing chamber 6, the refrigerating chamber 7, and the storage chamber 8 will be set within a set temperature range.

이와 같이 냉동실(6)과 냉장실(7) 및 저장실(8)에 각각 설정온도 범위를 설정하는 것은 상기 냉동실과 냉장실 및 저장실의 냉장온도 및 냉동온도를 일정하게 유지시킴으로써, 육고기나 생선 및 김치와 같은 음식물들의 고유한 맛을 가능한 한 그대로 유지시킴과 동시에 채소와 같이 상하기 쉬운 음식물들을 장기간 신선하게 보관할 수 있도록 한다.As such, setting the set temperature ranges in the freezer compartment 6, the refrigerator compartment 7, and the storage compartment 8 respectively maintains the refrigerating and freezing temperatures of the freezer compartment, the refrigerating compartment, and the storage compartment, such as meat, fish, and kimchi. Keep foods as intact as possible, while keeping food perishables such as vegetables fresh for a long time.

한편, 상기 냉장실(7)과 저장실(8)은 각각 김치를 저장시키거나 숙성시키는 기능을 가지며, 상기 제어부에는 냉장실 및 저장실에 김치를 저장시킬 때와 숙성시킬 때에 설정온도 범위가 각각 다르게 설정된다는 것은 이해 가능하다.On the other hand, the refrigerating compartment (7) and the storage compartment (8) has a function to store or mature kimchi, respectively, and the control unit is set to a different set temperature range when storing and aging kimchi in the refrigerating compartment and storage compartment, respectively It is understandable.

또한, 상기 냉장실(7)과 저장실(8)에는 야채나 과일과 같은 음식물만을 저장시킬 수도 있으며, 이때에도 냉장실 및 저장실의 설정온도 범위는 다르게 설정된다.In addition, the refrigerating compartment 7 and the storage compartment 8 may store only foods such as vegetables or fruits, and at this time, the set temperature ranges of the refrigerating compartment and the storage compartment are different.

이와 같은 냉장고의 냉각 작용을 위해, 상기 압축기(1)에서 냉매를 압축하여 고온고압의 냉매를 응축기(2)에 압송하고, 상기 응축기(2)에서 응축된 냉매를 삼방밸브(3)에 보낸다.For the cooling operation of the refrigerator, the compressor 1 compresses the refrigerant, presses the refrigerant having a high temperature and high pressure into the condenser 2, and sends the refrigerant condensed in the condenser 2 to the three-way valve 3.

이때, 상기 냉장실(7) 및 저장실(8)의 실내온도가 설정온도 범위를 만족함과 동시에 냉동실(6)의 실내온도가 상한치 온도 이상이 되면, 상기 삼방밸브(3)는 제어부의 제어에 의해 F 사이클 모드로 개방된다.At this time, when the room temperature of the refrigerating chamber 7 and the storage chamber 8 satisfies the set temperature range and the room temperature of the freezing chamber 6 becomes higher than the upper limit temperature, the three-way valve 3 is controlled by the controller. Open in cycle mode.

이와 같이 삼방밸브(3)가 F 사이클 모드로 개방되면, 상기 삼방밸브(3)를 통과한 냉매는 제 1 팽창장치(4)를 거쳐 냉동실용 증발기(6a)를 따라 순환되는 F 사이클을 수행한다.When the three-way valve 3 is opened in the F cycle mode as described above, the refrigerant passing through the three-way valve 3 performs an F cycle circulated along the freezer compartment evaporator 6a through the first expansion device 4. .

또한, 상기 냉장실(7) 또는 저장실(8)의 실내온도가 설정온도의 상한치 온도 보다 높아지면 상기 삼방밸브(3)는 R/F 사이클 모드로 개방된다.In addition, when the room temperature of the refrigerating chamber 7 or the storage chamber 8 becomes higher than the upper limit temperature of the set temperature, the three-way valve 3 is opened in the R / F cycle mode.

이와 같이 삼방밸브(3)가 R/F 사이클 모드로 개방되면, 상기 삼방밸브(3)를 통과한 냉매는 제 2 팽창장치(5)를 거쳐 냉장실용 증발기(7a)와 냉동실용 증발기(6a)를 순차적으로 순환하는 R/F 사이클을 수행한다.When the three-way valve 3 is opened in the R / F cycle mode as described above, the refrigerant passing through the three-way valve 3 passes through the second expansion device 5 to the refrigerator compartment evaporator 7a and the freezer compartment evaporator 6a. Perform an R / F cycle that cycles sequentially.

이때, 상기 냉장실(7)과 저장실(8)의 일측에 설치된 댐퍼(9,9a)를 각각 선택적으로 개폐시킴으로써 냉장실(7)과 저장실(8)에 냉기를 공급 또는 차단시킨다.At this time, by selectively opening and closing the dampers (9, 9a) provided on one side of the refrigerating chamber (7) and the storage chamber (8), the cold air is supplied or blocked to the refrigerating chamber (7) and the storage chamber (8).

다음으로, 상기 냉동실(6)과 냉장실(7) 및 저장실(8)의 실내온도가 모두 설정온도 범위를 만족하면, 상기 제어부에 의해 압축기(1)의 운전이 정지된다.Next, when the indoor temperatures of the freezer compartment 6, the refrigerating compartment 7 and the storage compartment 8 both satisfy the set temperature range, the operation of the compressor 1 is stopped by the controller.

이에 따라, 상기 냉동실용 증발기(6a)과 냉장실용 증발기(7a)에는 냉매의 유동이 거의 없는 상태가 된다.Accordingly, the freezing chamber evaporator 6a and the refrigerating chamber evaporator 7a have almost no flow of refrigerant.

한편, 일반적인 냉장고에 있어서 냉동실의 내부는 약 -18℃ 정도로 유지되며, 냉장실의 내부는 약 3℃ 정도로 유지된다.On the other hand, in a typical refrigerator, the interior of the freezer compartment is maintained at about -18 ℃, the interior of the refrigerator compartment is maintained at about 3 ℃.

이에 따라, 온도차가 큰 냉장실 내부와 냉장실용 증발기의 냉매 사이에는 열교환이 활발하게 진행되고, 상기 열교환에 의해 냉장실용 증발기의 온도는 점차적으로 상승하게 된다.Accordingly, heat exchange is actively performed between the inside of the refrigerating chamber having a large temperature difference and the refrigerant of the evaporator for the refrigerating chamber, and the temperature of the refrigerating chamber evaporator is gradually raised by the heat exchange.

또한, 냉장고 시스템과 외부공기가 열교환됨에 따라 상기 냉장실용 증발기(7a)에 위치하는 냉매는 그 온도가 상승된다.In addition, as the refrigerator system and the outside air heat exchange, the temperature of the refrigerant located in the refrigerator compartment evaporator 7a is increased.

시간이 지남에 따라 냉장실용 증발기(7a)는 주위의 온도와 열적 평형을 이루려고 하는데, 본 발명에서는 냉장실용 증발기(7a)의 온도가 얼음이 녹는 온도 이상이 되면 냉장팬(7b)을 회전시킨다.As time passes, the refrigerator evaporator 7a attempts to achieve thermal equilibrium with the ambient temperature. In the present invention, when the temperature of the refrigerator compartment evaporator 7a becomes higher than the melting temperature of the ice, the refrigerator fan 7b is rotated. .

상기 냉장팬(7b)을 회전시킴에 의해 냉장실용 증발기(7a)의 냉매와 주변의 공기를 보다 빨리 열교환시키도록 하여 상기 냉장실용 증발기(7a)에 결빙된 서리를 보다 빨리 녹게한다.By rotating the refrigerating fan 7b, the refrigerant in the refrigerating compartment evaporator 7a and the surrounding air are exchanged more quickly, thereby melting the frost frozen in the refrigerating compartment evaporator 7a more quickly.

또한, 상기와 같이 냉장팬(7b)이 회전될 때에 냉장실(7) 및 저장실(8)에 설치된 댐퍼(9,9a)를 모두 개방시킴으로써, 상기 냉장실용 증발기(7a)에 결빙된 서리가 녹으면서 발생되는 습기를 냉장실(7) 및 저장실(8)에 공급하도록 한다.In addition, by opening both the dampers 9 and 9a provided in the refrigerating chamber 7 and the storage chamber 8 when the refrigerating fan 7b is rotated as described above, while the frost frozen in the refrigerating chamber evaporator 7a melts. The generated moisture is supplied to the refrigerating chamber 7 and the storage chamber 8.

상기 냉장팬(7b)을 이용한 냉장실용 증발기의 제상은 냉장실(7)의 내부온도가 설정온도 범위의 상한치 온도로 증가될 때까지 행해지고, 상기 냉장실(7)의 내부온도가 상하치 온도까지 높아지면 상기 냉장고는 압축기(1)의 운전을 재시작한다.The defrost of the refrigerating compartment evaporator using the refrigerating fan 7b is performed until the internal temperature of the refrigerating compartment 7 increases to an upper limit temperature of a set temperature range, and when the internal temperature of the refrigerating compartment 7 rises to an upper and lower temperature. The refrigerator restarts operation of the compressor 1.

이상에서와 같이, 본 발명은 냉동실(6)과 냉장실(7)의 실내온도가 제어부에 저장된 설정온도 범위를 만족시킴에 의해 압축기(1)의 운전이 정지될 때마다 냉장팬(7b)을 가동하여 냉장실용 증발기(7a)에 결빙된 서리를 조금씩이라도 제거해줌으로써 히터를 이용한 냉장실용 증발기(7a)의 제상 주기를 연장시킬 수 있다.As described above, the present invention operates the refrigerating fan 7b whenever the operation of the compressor 1 is stopped by satisfying the set temperature range stored in the control unit in the freezing chamber 6 and the refrigerating chamber 7. By removing the frost frozen in the refrigerator evaporator 7a little by little, the defrost cycle of the refrigerator evaporator 7a using a heater can be extended.

이와 같이 히터를 이용한 냉장실용 증발기(7a)의 제상 주기를 연장시킴으로써, 상기 제상을 행하면서 냉장고 내부의 온도를 높였다가 다시 냉각운전을 행하면서 냉장고의 내부 온도를 낮추는 과정에서 발생되는 냉장고 시스템의 열손실을 상당히 감소시킬 수 있다.By extending the defrost cycle of the refrigerating chamber evaporator 7a using the heater as described above, the heat of the refrigerator system generated in the process of lowering the internal temperature of the refrigerator while increasing the temperature inside the refrigerator while performing the defrost and then performing a cooling operation again. The loss can be significantly reduced.

또한, 상기와 같은 제상 방법으로 서리를 녹여 냉장실(7) 및 저장실(8)에 습기를 공급함으로써 저장되는 과일 또는 야채로부터 수분이 증발되는 것을 감소시키도록 하여 과일 및 야채가 보다 오랫동안 신선도를 유지할 수 있도록 한다.In addition, by melting the frost in the defrosting method as described above to supply moisture to the refrigerating compartment (7) and the storage compartment (8) to reduce the evaporation of moisture from the stored fruit or vegetable to keep the fruit and vegetables fresh longer Make sure

이상에서와 같이, 본 발명은 냉장팬을 이용하여 냉장실의 증발기를 제상시킴으로써 히터를 이용한 제상의 주기를 연장시켜 냉장고의 전체적인 열손실 및 소비전력을 상당히 저감시킬 수 있다.As described above, the present invention can extend the defrost cycle using the heater by defrosting the evaporator of the refrigerating chamber by using the refrigerating fan, which can significantly reduce the overall heat loss and power consumption of the refrigerator.
