A control method of a refrigerator is disclosed. An object of the present invention is to more effectively control the operation of the refrigerator compartment fan and the freezer compartment fan to significantly reduce the noise and power consumption of the refrigerator. The control method of the refrigerator according to the present invention for this purpose is to operate the refrigerator compartment fan to cool the refrigerator compartment, while operating the freezer compartment fan at a second rotation speed lower than the first rotation speed while operating the refrigerator compartment fan, After the operation is completed, the freezer compartment fan is operated at a first rotational speed.
Description
본 발명은 냉장고에 관한 것으로, 특히 냉장실 및 냉동실 각각에 증발기가 마련되는 냉장고의 제어 방법에 관한 것이다. The present invention relates to a refrigerator, and more particularly, to a control method of a refrigerator provided with an evaporator in each of a refrigerator compartment and a freezer compartment.
일반적으로 냉장고의 본체는 중간 격벽에 의해 구획되는 냉동실과 냉장실이 마련되고, 냉동실과 냉장실 각각에는 본체에 힌지 결합되어 냉동실과 냉장실을 개폐하는 도어가 설치된다. 냉동실의 내부 벽면에는 냉기를 생성하여 냉동실 내부에 공급하기 위한 증발기와 팬이 구비된다. 또한 냉장실의 내부 벽면에도 냉기를 생성하여 냉장실 내부에 공급하기 위한 또 다른 증발기와 팬이 구비된다. 또 다른 구조의 냉장고로는 냉장실에 팬이 아닌 댐퍼를 설치하여 냉장실의 냉기를 조절하는 구조의 냉장고를 들 수 있다. In general, the main body of the refrigerator is provided with a freezer compartment and a refrigerating compartment partitioned by an intermediate partition, and each of the freezer compartment and the refrigerating compartment is hinged to the main body is provided with a door for opening and closing the freezer compartment and the refrigerating compartment. An inner wall of the freezer compartment is provided with an evaporator and a fan for generating cold air and supplying it into the freezer compartment. There is also another evaporator and fan on the inner wall of the refrigerating compartment for generating cold air and supplying it into the refrigerating compartment. Another structure of the refrigerator may include a refrigerator having a damper instead of a fan in the refrigerator compartment to control cold air in the refrigerator compartment.
냉장고의 각 고내 온도가 목표 냉각 온도보다 높은 경우에는 냉기를 발생시켜 고내에 공급함으로써 고내 온도를 떨어뜨린다. 고 내에 냉기를 공급하기 위하여 팬을 회전시켜 증발기 주변의 냉기를 고내로 불어 넣게 된다. 이와 같은 팬의 회전 때문에 소음과 전력 소비가 증가하게 된다. When the temperature in each refrigerator of the refrigerator is higher than the target cooling temperature, cold air is generated and supplied into the refrigerator to lower the temperature in the refrigerator. The fan is rotated to supply cold air into the air, and the cold air around the evaporator is blown into the air. This rotation of the fan increases noise and power consumption.
본 발명은 냉장실 팬 및 냉동실 팬의 운전을 보다 효율적으로 제어하여 냉장고의 소음 및 전력 소모를 크게 감소시키는데 그 목적이 있다. An object of the present invention is to more effectively control the operation of the refrigerator compartment fan and the freezer compartment fan to significantly reduce the noise and power consumption of the refrigerator.
이와 같은 목적의 본 발명에 따른 냉장고의 제어 방법은 냉장실을 냉각하기 위해 냉장실 팬을 운전하고, 냉장실 팬을 운전하는 동안 냉동실 팬을 제 1 회전 속도보다 낮은 제 2 회전 속도로 운전하며, 냉장실 팬의 운전이 완료되면 냉동실 팬을 제 1 회전 속도로 증가시켜 운전한다. The control method of the refrigerator according to the present invention for this purpose is to operate the refrigerator compartment fan to cool the refrigerator compartment, while operating the freezer compartment fan at a second rotation speed lower than the first rotation speed while operating the refrigerator compartment fan, After the operation is completed, the freezer compartment fan is operated at a first rotational speed.
본 발명에 따른 또 다른 냉장고의 제어 방법은 냉장실과 냉동실을 모두 냉각할 때 냉장실 팬과 냉동실 팬을 모두 운전하되, 냉장실 팬을 제 1 회전 속도로 운전하고 냉동실 팬은 제 1 회전 속도보다 낮은 제 2 회전 속도로 운전한다. In another refrigerator control method according to the present invention, while cooling both the refrigerating compartment and the freezing compartment, both the refrigerating compartment fan and the freezing compartment fan are operated, the refrigerating compartment fan is operated at a first rotational speed, and the freezer compartment fan is lower than the first rotational speed. Drive at rotation speed.
이와 같이 이루어지는 본 발명의 바람직한 실시예를 도 1 및 도 2를 참조하면 다음과 같다. 먼저 도 1은 본 발명의 실시예에 따른 냉장고의 냉매 사이클을 나타낸 도면으로서, 도 1에 나타낸 바와 같이, 압축기(102)와 응축기(104), 팽창 수단인 모세관(108), 냉장실 증발기(110), 냉동실 증발기(114) 등이 냉매관을 통해 연결되어 폐회로를 구성한다. 또, 응축기 팬(106)을 구동하는 응축기 팬 모터(106a)와 냉장실 팬(112)을 구동하는 냉장실 팬 모터(112a), 냉동실 팬(116)을 구동하는 냉동실 팬 모터(116a)가 더 구비된다. 이처럼 냉장실과 냉동실 각각에 냉장실 팬(112)과 냉동실 팬(116)이 마련되어 냉장실과 냉동실에 독립적인 냉기 공급이 이루어진다. Referring to Figures 1 and 2 a preferred embodiment of the present invention made as described above are as follows. First, FIG. 1 is a view illustrating a refrigerant cycle of a refrigerator according to an embodiment of the present invention. As shown in FIG. 1, a compressor 102, a condenser 104, a capillary tube 108 as an expansion means, and a refrigerating chamber evaporator 110 are illustrated. , Freezer compartment evaporator 114 is connected via a refrigerant pipe to form a closed circuit. Further, a condenser fan motor 106a for driving the condenser fan 106, a refrigerating chamber fan motor 112a for driving the refrigerating chamber fan 112, and a freezer compartment fan motor 116a for driving the freezer compartment fan 116 are further provided. . As described above, the refrigerator compartment fan 112 and the freezer compartment fan 116 are provided in the refrigerating compartment and the freezing compartment, respectively, and independent cold air is supplied to the refrigerating compartment and the freezing compartment.
본 발명의 실시예에서는 냉매의 팽창이 하나의 모세관(108)을 통해 이루어진 다음 냉장실 증발기(110)와 냉동실 증발기(114)에 차례로 공급된다. 따라서 모세관(108)에서의 감압은 냉동실 증발기(114)에서 요구되는 증발 온도에 적합하게 이루어진다. 냉동실 증발기(114)의 증발 온도를 기준으로 냉매의 감압이 이루어질 경우 냉장실과 냉동실의 각각의 목표 온도가 다르기 때문에 과냉각 또는 부족 냉각이 이루어질 수 있으므로 각 팬(112, 116)의 운전 시간을 적절히 조절하여 과냉각 또는 부족 냉각 문제를 해결한다. 이와 같이 냉장실 팬(112)과 냉동실 팬(116)을 운용함에 따라 소음과 전력 소비가 초래되는데, 도 2의 타이밍 차트와 같은 제어를 통해 팬에 의한 소음 및 전력 소비를 현저히 줄일 수 있다. In the embodiment of the present invention, the expansion of the refrigerant is made through one capillary tube 108 and then supplied to the refrigerator compartment evaporator 110 and the freezer compartment evaporator 114 in turn. Therefore, the decompression in the capillary 108 is adapted to the evaporation temperature required in the freezer compartment evaporator 114. When the refrigerant is depressurized based on the evaporation temperature of the freezer compartment evaporator 114, since the target temperatures of the refrigerating compartment and the freezer compartment are different, supercooling or undercooling may be performed, thereby appropriately adjusting the operating time of each fan 112 and 116. Solve the problem of overcooling or undercooling. As such, operation of the refrigerating compartment fan 112 and the freezer compartment fan 116 results in noise and power consumption. Noise and power consumption by the fan can be significantly reduced by controlling the timing chart of FIG. 2.
도 2는 본 발명의 실시예에 따른 냉장고의 제어 방법을 나타낸 타이밍차트이다. 먼저 도 2의 (I)은 냉장실과 냉동실을 모두 냉각하되, 냉장실을 먼저 냉각하고 냉장실의 고내 온도가 목표 온도에 도달하면 냉동실을 냉각하는 형태이다. 도 2(I)에 나타낸 바와 같이, 냉각을 위해 압축기(102)를 운전할 때 냉장실을 냉각시키기 위해 냉장실 팬(112)도 함께 운전한다. 이 때 냉장실 팬(112)을 운전하는 동안 냉동실 팬(116)을 제 1 회전 속도(HIGH)보다 낮은 제 2 회전 속도(LOW)로 운전한다. 냉장실의 고내 온도가 목표 냉각 온도에 도달하면(t_R)에서 냉장실 팬(112)의 운전을 종료하고 냉동실 팬(116)을 제 2 회전 속도(LOW)에서 제 1 회전 속도(HIGH)로 높여서 운전한다. 냉동실의 고내 온도가 냉동실 목표 냉각 온도에 도달하면(t_F)에서는 냉동실 팬(116)의 운전을 종료한다. 즉 냉장실의 냉각이 이루어지는 동안 냉장실 증발기(110)로부터 냉동실 증발기(114)로 유입되는 소량의 액 냉매에 대응하여 냉동실 팬(112)을 비교적 낮은 제 2 속도(LOW)로 회전시킴으로써 냉동실 팬(112)에 의한 소음 및 전력 소비가 현저히 감소한다. 뿐만 아니라, 냉장실의 냉각이 이루어지는 동안 냉동실 증발기(114)에서 발생하는 냉기를 냉동실에 서서히 불어넣음으로써 냉동실 고내 온도의 급격한 상승을 억제하여 냉동실의 기능을 향상시킨다. 또한 냉장실 팬(112)의 운전 초기에는 이 냉장실 팬(112)의 회전 속도를 단계적으로 증가시키는 것도 가능한데, 이는 압축기(102)가 기동하더라도 냉장실 증발기(110)에서는 아직 충분한 냉매의 감압이 이루어지지 않을 수 있으므로, 이 때 냉장실 팬(112)의 회전 속도를 낮춤으로써 불필요한 냉장실 팬(112)의 고속 회전에 따른 소음 및 전력 소비가 증가하지 않도록 하기 위한 것이다. 2 is a timing chart illustrating a control method of a refrigerator according to an embodiment of the present invention. First, (I) of FIG. 2 is to cool both the refrigerating compartment and the freezing compartment, but to cool the refrigerating compartment first and the freezer compartment when the internal temperature of the refrigerating compartment reaches the target temperature. As shown in FIG. 2 (I), when operating the compressor 102 for cooling, the refrigerator compartment fan 112 is also operated together to cool the refrigerator compartment. At this time, while operating the refrigerator compartment fan 112, the freezer compartment fan 116 is operated at a second rotation speed LOW lower than the first rotation speed HIGH. When the internal temperature of the refrigerating compartment reaches the target cooling temperature (t_R), the operation of the refrigerating compartment fan 112 is terminated and the freezer compartment 116 is operated by increasing the freezing compartment fan 116 from the second rotational speed LOW to the first rotational speed HIGH. . When the internal temperature of the freezer compartment reaches the freezer target cooling temperature (t_F), the operation of the freezer compartment fan 116 is terminated. That is, the freezer compartment 112 is rotated by rotating the freezer compartment 112 at a relatively low second speed LOW in response to a small amount of liquid refrigerant flowing into the freezer compartment evaporator 114 from the refrigerator compartment evaporator 110 while the refrigerator compartment is cooled. Noise and power consumption are significantly reduced. In addition, by gradually blowing the cold air generated in the freezer compartment evaporator 114 into the freezer compartment while the refrigerating chamber is cooled, the sudden rise of the freezer compartment temperature is suppressed to improve the function of the freezer compartment. It is also possible to increase the rotational speed of the refrigerating compartment fan 112 step by step at the beginning of the operation of the refrigerating compartment fan 112, which is not yet sufficiently depressurized in the refrigerating compartment evaporator 110 even when the compressor 102 is started. At this time, by lowering the rotational speed of the refrigerating compartment fan 112 is to prevent the noise and power consumption due to the high-speed rotation of the unnecessary refrigerating compartment fan 112 is not increased.
도 2의 (II)는 냉장실만을 단독으로 냉각하고 냉동실은 냉각하지 않는 경우, 즉 냉동실의 고내 온도는 냉동실 목표 냉각 온도에 도달해 있고, 냉장실의 고내 온도는 아직 냉장실 목표 냉각 온도에 도달하지 못한 경우의 운전 제어 방법을 나타낸 도면이다. 도 2의 (II)에 나타낸 바와 같이, 냉동실의 고내 온도가 이미 목표 냉각 온도에 도달해 있기 때문에 냉동실 팬(116)은 운전하지 않고 오프 상태로 둔다. 이 때 냉장실의 고내 온도는 아직 목표 냉각 온도에 도달하지 못했으므로 냉장실의 고내 온도가 목표온도에 도달할 때(t_R)까지 압축기(102)와 냉장실 팬(112)을 함께 운전하여 냉장실을 냉각하되, 냉장실 팬(112)의 운전 초기에 회전 속도를 저속(LOW)에서 고속(HIGH)으로 단계적으로 높여서 냉매가 충분히 응축되지 않은 상태에서 불필요하게 냉장실 팬(112)을 고속 회전시키지 않음으로써 냉장실 팬(112)으로부터 발생하는 소음과 전력 소비를 감소시킨다.2 (II) is a case in which only the refrigerating compartment is cooled alone and the freezer compartment is not cooled, that is, the internal temperature of the freezer compartment has reached the freezer target cooling temperature, and the internal temperature of the refrigerator compartment has not yet reached the refrigerator compartment target cooling temperature. 2 is a diagram illustrating a driving control method of the same. As shown in FIG. 2 (II), since the freezer temperature of the freezer compartment has already reached the target cooling temperature, the freezer compartment fan 116 is turned off without operating. At this time, since the internal temperature of the refrigerator compartment has not yet reached the target cooling temperature, the refrigerator 102 is cooled by operating the compressor 102 and the refrigerator compartment fan 112 until the internal temperature of the refrigerator compartment reaches the target temperature (t_R), By increasing the rotational speed step by step from low to high in the initial stage of operation of the refrigerating compartment fan 112, the refrigerating compartment fan 112 is not rotated at a high speed in a state where the refrigerant is not sufficiently condensed. To reduce noise and power consumption.
도 2의 (III)은 (II)와는 반대의 경우인 냉동실만을 단독으로 냉각하고 냉장실은 냉각하지 않는 경우, 즉 냉장실의 고내 온도는 목표 냉각 온도에 도달해 있고 냉동실의 고내 온도는 아직 목표 냉각 온도에 도달하지 못한 경우의 운전 제어 방법을 나타낸 도면이다. 도 2의 (III)에 나타낸 바와 같이, 냉장실의 고내 온도가 이미 목표 냉각 온도에 도달해 있기 때문에 냉장실 팬(112)은 운전하지 않고 오프 상태로 둔다. 이 때 냉동실의 고내 온도는 아직 목표 냉각 온도에 도달하지 못했으므로 냉동실의 고내 온도가 목표 온도에 도달할 때(t_F)까지 압축기(102)와 냉동실 팬(116)을 함께 운전하여 냉동실을 냉각하되, 냉동실 팬(116)의 운전 초기에 회전 속도를 저속(LOW)에서 고속(HIGH)으로 단계적으로 높여서 냉매가 충분히 응축되지 않은 상태에서 불필요하게 냉동실 팬(116)을 고속 회전시키지 않음으로써 냉동실 팬(116)으로부터 발생하는 소음과 전력 소비를 감소시킨다. 2 (III) shows a case in which the freezer compartment alone and the refrigerator compartment are not cooled, which is the case opposite to (II), that is, the internal temperature of the refrigerator compartment has reached the target cooling temperature and the internal temperature of the freezer compartment is still the target cooling temperature. Fig. 1 shows a driving control method when the operation is not reached. As shown in (III) of FIG. 2, since the internal temperature of the refrigerator compartment has already reached the target cooling temperature, the refrigerator compartment fan 112 is not operated but is left off. At this time, since the freezer temperature of the freezer has not yet reached the target cooling temperature, the freezer compartment is cooled by operating the compressor 102 and the freezer fan 116 together until the freezer temperature reaches the target temperature (t_F), By increasing the rotational speed step by step from low to high in the initial stage of the operation of the freezer compartment 116, the freezer compartment fan 116 is not rotated at high speed without unnecessary condensation of the refrigerant. To reduce noise and power consumption.
앞서 설명한 도 2의 (I)은 냉장실의 목표 냉각 온도 도달 시간과 냉동실의 목표 냉각 온도 도달 시간이 서로 다른 경우를 나타낸 것이었는데, 도 2의 (IV)는 냉장실의 목표 냉각 온도 도달 시간과 냉동실의 목표 냉각 온도 도달 시간이 서로 동일한 경우를 나타낸 것이다. 도 2의 (IV)에 나타낸 바와 같이, 냉장실 및 냉동실 각각의 고내 온도가 목표 냉각 온도에 도달할 때(t_R=t_F)까지 압축기(102)와 냉장실 팬(112), 냉동실 팬(116)을 모두 운전한다.FIG. 2 (I) described above shows a case where the target cooling temperature reaching time of the refrigerating compartment and the target cooling temperature reaching time of the freezing compartment are different from each other. FIG. The case where the target cooling temperature arrival times are the same is shown. As shown in FIG. 2 (IV), the compressor 102, the refrigerator compartment fan 112, and the freezer compartment 116 are both opened until the internal temperature of each of the refrigerating compartment and the freezing compartment reaches the target cooling temperature (t_R = t_F). Drive.
이 때 냉장실 팬(112)은 운전 초기에 저속(LOW)에서 고속(HIGH)으로 단계적으로 회전 속도를 높여서 냉매가 충분히 응축되지 않은 상태에서 불필요하게 냉장실 팬(112)을 고속 회전시키지 않음으로써 냉장실 팬(112)으로부터 발생하는 소음과 전력 소비를 감소시킨다. 이와 달리 냉동실 팬(116)은 냉동실을 냉각하는 동안 저속(LOW)으로 회전시켜서 냉동실을 냉각함으로써 냉동실이 과냉각되는 것을 방지하고, 불필요한 소음 발생 및 전력 소비를 방지한다. At this time, the refrigerator compartment fan 112 gradually increases the rotational speed from low to high in the initial stage of operation so that the refrigerator compartment fan does not rotate unnecessarily at high speed in a state where the refrigerant is not sufficiently condensed. Reduce noise and power consumption from 112. In contrast, the freezer compartment fan 116 rotates at a low speed while cooling the freezer compartment to cool the freezer compartment, thereby preventing the freezer compartment from being overcooled, and preventing unnecessary noise generation and power consumption.
본 발명은 냉장실 팬 및 냉동실 팬의 회전 속도를 냉장고의 운전 상태에 따라 적절히 제어함으로써 팬의 불필요한 고속 회전을 억제하여 냉장고의 소음 및 전력 소모를 크게 감소시킨다. The present invention by controlling the rotation speed of the refrigerating compartment fan and the freezer fan according to the operating state of the refrigerator appropriately to suppress unnecessary high-speed rotation of the fan significantly reduces the noise and power consumption of the refrigerator.
