Description
본 발명은 냉장고의 운전방법에 관한 것으로, 더욱 상세하게는 냉장실이 상부에 냉동실이 하부에 설치되는 냉장고에서 냉동싸이클이 구동되지 않는 동안에 냉장실로의 냉기의 공급을 단속하는 댐퍼가 결빙되지 않도록 하는 냉장고의 운전방법에 관한 것이다.The present invention relates to a method of operating a refrigerator, and more particularly, a refrigerator in which a damper which controls the supply of cold air to the refrigerating compartment is not frozen while the refrigerating cycle is not driven in the refrigerating compartment in which the refrigerating compartment is installed at the lower portion thereof. The driving method of the.
먼저 도 1 및 도 2에 기초하면서 일반적인 냉장고의 구성 및 냉기의 흐름에 대하여 살펴보기로 한다.First, a configuration of a general refrigerator and a flow of cold air will be described based on FIGS. 1 and 2.
도 1 및 도 2에 도시한 냉장고는, 냉장실(2)이 상부에 그리고 냉동실(4)이 하부에 설치되어 있는 냉장고의 구성을 보이고 있다. 하부에 위치하는 냉동실(4)의 후방에는 열교환을 위한 증발기(6)가 설치되는 열교환챔버(5)가 형성되어 있다. 그리고 상기 열교환챔버(5)의 상부에는 증발기(6)와의 접촉에 의하여 생성된 냉기를 냉동실(4) 및 냉장실(2)로 순환시키기 위한 송풍팬(8)이 설치되어 있다.The refrigerator shown in FIG.1 and FIG.2 has shown the structure of the refrigerator in which the refrigerating chamber 2 is provided in the upper part and the freezing chamber 4 is provided in the lower part. At the rear of the freezing chamber 4 located at the lower portion, a heat exchange chamber 5 in which an evaporator 6 for heat exchange is installed is formed. And an upper part of the heat exchange chamber (5) is provided with a blowing fan (8) for circulating the cold air generated by contact with the evaporator (6) to the freezing chamber (4) and the refrigerating chamber (2).
그리고 상방에 설치된 냉장실(2)로의 냉기의 공급은 냉장실덕트(3)를 경유하여 이루어지고, 상기 냉장실덕트(3) 상에는 냉장실로의 냉기의 공급여부를 단속하는 댐퍼(9)가 설치되어 있다. 상기 댐퍼(9)가 열리게 되면 냉장실로 냉기가 공급될 수 있는 상태이고, 닫히게 되면 냉장실로의 냉기의 공급은 중단된다. 물론 상기 댐퍼(9)의 개폐여부는 냉장실(2) 내부에 설치되어 있는 온도감지센서에 의하여 결정된다. 또는 기계식댐퍼일 경우에는 냉장실 온도에 의하여, 댐퍼(9)가 스스로 닫히게 된다. 그러나 기계식댐퍼일 경우에는, 완전하게 닫히는 것은 아니고, 약간의 공간을 열어 둔 상태로 닫히게 된다.The cold air is supplied to the refrigerating chamber 2 provided above via the refrigerating chamber duct 3, and a damper 9 is provided on the refrigerating chamber duct 3 to control whether cold air is supplied to the refrigerating chamber. When the damper 9 is opened, the cold air can be supplied to the refrigerating compartment, and when the damper 9 is closed, the supply of cold air to the refrigerating compartment is stopped. Of course, the opening and closing of the damper (9) is determined by the temperature sensor installed in the refrigerating chamber (2). Or in the case of a mechanical damper, the damper 9 is closed by itself by the refrigerator compartment temperature. In the case of a mechanical damper, however, it is not completely closed, but is closed with some space open.
도 1은 압축기(7)가 구동되는 상태, 즉 냉동싸이클이 동작하면서 냉기가 생성되고 있는 상태를 도시한 것으로, 도시한 바와 같이 증발기(6)의 표면에서 열교환에 의하여 생성되는 냉기는 송풍팬(8)에 의하여 일부는 냉동실(4)로, 그리고 다른 일부는 냉장실(2)로 공급된다. 이러한 냉기의 공급경로가 화살표로 도시되어 있다. 그리고 도 2에는 압축기(7)의 구동이 정지된 상태의 냉기의 흐름을 도시하고 있다. 그리고 냉장고의 구동에 있어서, 상기 압축기(7)와 송풍팬(8)은 동시에 동작하게 된다. 즉 압축기(7)가 구동하게 되면 송풍팬(8)은 온상태로 되고, 압축기(7)가 오프되면 상기 송풍팬(8)도 같이 오프된다. 이는 압축기(7)가 구동함에 따라서 냉기가 생성되고 있는 경우에만, 송풍팬(8)을 구동함으로써 냉기를 공급하기 위한 것이다.FIG. 1 illustrates a state in which the compressor 7 is driven, that is, a state in which cold air is generated while the refrigeration cycle is operating. As illustrated, cold air generated by heat exchange on the surface of the evaporator 6 is blown with a fan. 8) part is supplied to the freezer compartment 4 and the other part to the refrigerating compartment 2. This cold air supply path is shown by the arrow. 2 shows the flow of cold air in the state where the driving of the compressor 7 is stopped. In the driving of the refrigerator, the compressor 7 and the blowing fan 8 are operated at the same time. That is, when the compressor 7 is driven, the blowing fan 8 is turned on, and when the compressor 7 is turned off, the blowing fan 8 is also turned off. This is for supplying cold air by driving the blower fan 8 only when cold air is generated as the compressor 7 is driven.
이와 같이 냉동실(4)이 하방에, 냉장실(2)이 상방에 설치된 냉장고에 있어서, 냉장실(2)의 온도는 설정온도를 만족하지 못하면 댐퍼(9)는 열려 있는 상태를 유지하게 된다. 이 때 냉동실(4)의 온도가 설정온도 이하로 내려가게 되면 압축기(7)의 구동이 정지된다. 이렇게 냉장실(2)의 온도가 만족하지 못한 상태에서 압축기(7)의 구동이 정지되면 송풍팬(8)의 구동도 정지된다. 이렇게 송풍팬(8)이 정지하게 되면, 댐퍼(9)가 열린 상태이기 때문에 상부에 있는 냉장실(2)의 공기가 상기 댐퍼(9)를 통하여 역류하는 현상이 발생하게 된다.As described above, in the refrigerator in which the freezer compartment 4 is below and the refrigerating compartment 2 is located above, the damper 9 is kept open when the temperature of the refrigerating compartment 2 does not satisfy the set temperature. At this time, when the temperature of the freezing chamber 4 falls below the set temperature, the driving of the compressor 7 is stopped. When the driving of the compressor 7 is stopped while the temperature of the refrigerating chamber 2 is not satisfactory, the driving of the blower fan 8 is also stopped. When the blower fan 8 is stopped in this way, the damper 9 is open, so that air in the refrigerating chamber 2 in the upper portion flows back through the damper 9.
이렇게 역류현상이 발생하게 되면, 냉기의 공급시 냉기에 노출되어 있는 댐퍼는 상대적으로 매우 저온상태의 것이나, 냉장실(2) 내부는 이보다는 고온상태이다. 따라서 저온상태의 댐퍼(9)가 상대적으로 고온상태의 냉장실(2) 내부의 공기와 접촉하게 되면 댐퍼(9)의 표면에는 결빙현상이 발생하게 된다. 이러한 결빙은, 냉장실 내부에 포함되어 있는 습기가 댐퍼(9)의 표면, 특히 댐퍼가 구비하고 있는 배플에 얼어붙게 되는 것에 의하여 발생하는 것이다. 또한 상기 댐퍼(9) 뿐만 아니라, 냉장실덕트(3) 내부의 표면에서 결빙현상이 발생되기도 한다.When the reverse flow phenomenon occurs, the damper exposed to the cold air at the time of supplying the cold air is relatively very low temperature, but the inside of the refrigerating chamber 2 is a higher temperature than this. Therefore, when the damper 9 in the low temperature state comes into contact with the air inside the refrigerating chamber 2 in the relatively high temperature state, freezing occurs on the surface of the damper 9. This freezing is caused by the moisture contained in the refrigerating chamber being frozen on the surface of the damper 9, in particular the baffle provided by the damper. In addition to the damper (9), freezing may occur on the surface of the refrigerating chamber duct (3).
이러한 결빙현상을 방지하기 위하여, 즉 압축기(7)가 정지된 상태에서 냉장실(2)의 공기가 냉동실(4) 측으로 역류하는 것을 방지하기 위하여 압축기(7)가 정지된 후에도 상기 송풍팬(8)을 지속적으로 동작시키는 방법이 제안되었다.In order to prevent such freezing, that is, to prevent the air in the refrigerating compartment 2 from flowing back to the freezing compartment 4 in the state in which the compressor 7 is stopped, the blowing fan 8 even after the compressor 7 is stopped. A method for continuously operating the system has been proposed.
그러나 압축기(7)가 정지된 상태에서 상기 송풍팬(8)을 지속적으로 동작시키면, 냉동실(4)의 냉기가 냉장실로 유입될 우려가 있다. 냉동실(4)의 냉기가 냉장실(2)로 유입되면, 냉장실(2)에 지속적으로 냉기가 공급되는 결과를 초래하게 되고, 따라서 냉장실(2)이 과냉될 우려가 있다. 특히 냉장실(2)에서 냉기토출공과 인접하게 보관되고 있는 식품의 과냉우려가 높아진다.However, if the blower fan 8 is continuously operated while the compressor 7 is stopped, there is a fear that the cold air of the freezer compartment 4 flows into the refrigerating compartment. When the cold air in the freezer compartment 4 flows into the refrigerating compartment 2, the result is that the cold air is continuously supplied to the refrigerating compartment 2, so that the refrigerating compartment 2 may be overcooled. Especially in the refrigerating chamber 2, the overcooling concern of the food stored adjacent to the cold air discharge | air hole becomes high.
상기 목적을 달성하기 위한 본 발명에 의하면, 댐퍼의 결빙을 방지할 수 있음과 동시에 냉장실의 과냉을 방지하는 냉장고의 운전방법을 제공하는 것을 목적으로 한다.According to the present invention for achieving the above object, an object of the present invention is to provide a method of operating a refrigerator that can prevent freezing of a damper and at the same time prevent overcooling of a refrigerating compartment.
그리고 이와 같은 본 발명의 목적은 송풍팬의 제어하는 것에 의하여 달성될 것이고, 본 발명은 이러한 사상에 기초하고 있다.And this object of the present invention will be achieved by controlling the blowing fan, and the present invention is based on this idea.
도 1은 냉장고의 구성을 보인 단면도.1 is a cross-sectional view showing the configuration of a refrigerator.
도 2는 압축기가 정지된 상태의 내부 공기 흐름을 보인 단면도.Figure 2 is a cross-sectional view showing the internal air flow of the compressor is stopped.
상기 목적을 달성하기 위한 본 발명에 의한 냉장고의 운전방법은, 냉장실로 냉기를 공급하는 냉기공급경로상에 설치된 댐퍼가 열린 상태에서 압축기의 구동이 정지되면, 상부의 냉장실의 냉기가 냉기공급경로를 통하여 하부로 역류하는 것을 방지하는 최저회전수로 송풍팬을 구동시키는 것을 기술적 요지로 하고 있다.The operation method of the refrigerator according to the present invention for achieving the above object is that, when the compressor is stopped in the state in which the damper is installed on the cold air supply path for supplying cold air to the refrigerator compartment, the cold air in the upper refrigerating compartment to the cold air supply path The technical gist of the blower fan is to drive the fan at the minimum rotational speed to prevent the flow back to the lower part.
이와 같은 본 발명의 방법에 의하면, 댐퍼가 열린상태에서 압축기의 구동이 정지되면 상부의 냉장실에서 하부의 냉동실로 냉기가 역류하는 것을 방지할 수 있음과 동시에, 냉동실의 냉기가 냉장실로 지속적으로 공급되어 과냉되는 것을 방지할 수 있게 되는 효과가 기대된다.According to the method of the present invention, when the operation of the compressor is stopped while the damper is open, it is possible to prevent the reflux of the cold air flows from the upper refrigerating chamber to the lower freezing chamber and at the same time, the cold air of the freezing chamber is continuously supplied to the refrigerating chamber. An effect that can prevent the overcooling is expected.
본 발명의 다른 실시예에 의하면, 상기 송풍팬은 일정 시간 구동되는 것을 특징으로 한다.According to another embodiment of the present invention, the blowing fan is characterized in that it is driven for a predetermined time.
다음에는 보다 상세하게 본 발명에 의한 운전방법을 설명하기로 한다.Next, the operation method according to the present invention will be described in more detail.
본 발명의 설명에 있어서는, 구성상 필요한 부분에 대해서는 도 1 및 도 2를 참조하면서 설명하기로 한다.In the description of the present invention, the parts necessary for configuration will be described with reference to FIGS. 1 and 2.
냉장고가 운전되는 동안에는 도 1에 도시한 바와 같은 냉기의 흐름이 형성된다. 즉 압축기(5)가 구동됨과 동시에 증발기(6)가 위치하는 열교환챔버(5)에서는 냉기가 생성된다. 이렇게 생성된 냉기는 송풍팬(8)에 의하여 하방의 냉동실(4)로 그리고 다른 일부는 상방의 냉장실(2)로 공급된다. 냉장실(2)로의 냉기의 공급은 댐퍼(9)가 설치되어 있는 냉장실덕트(3)를 따라 공급될 것이다.While the refrigerator is in operation, a flow of cold air is formed as shown in FIG. 1. That is, cold air is generated in the heat exchange chamber 5 in which the compressor 5 is driven and the evaporator 6 is located. The cold air thus produced is supplied by the blowing fan 8 to the lower freezing chamber 4 and the other part to the upper refrigerating chamber 2. The supply of cold air to the refrigerating chamber 2 will be supplied along the refrigerating chamber duct 3 in which the damper 9 is installed.
그리고 본 발명에 따르면, 댐퍼(9)가 닫히지 않은 상태에서 압축기(7)의 구동이 정지되면 상기 송풍팬(8)은 냉기의 역류가 방지될 정도의 최저회전수를 구동된다. 즉 종래에 따르면 압축기(7)의 구동이 정지되면 상기 송풍팬(8)의 구동도 정지되었으나, 본 발명에 따르면 압축기(7)의 구동이 정지되더라도, 댐퍼(9)가 열린 상태이면 송풍팬(8)은 상부에 있는 냉장실(2)에서 하부에 있는 냉동실(4)로 냉기가 역류하지 않을 정도의 최저회전수를 가지고 회전하게 되는 것이다.According to the present invention, when the driving of the compressor 7 is stopped while the damper 9 is not closed, the blower fan 8 is driven at the minimum rotational speed such that reverse flow of cold air is prevented. That is, according to the present invention, when the driving of the compressor 7 is stopped, the driving of the blower fan 8 is also stopped. According to the present invention, even when the driving of the compressor 7 is stopped, the blower fan is opened when the damper 9 is open. 8) is to rotate with the minimum number of revolutions so that the cold air does not flow back from the refrigerating chamber (2) in the upper portion to the freezing chamber (4) in the lower portion.
이렇게 압축기(7)가 정지된 상태에서 송풍팬(8)이 최저회전수를 가지고 회전하도록 구성하는 것에 의하여, 상부의 냉장실(2)에서 냉장실덕트(3)를 통하여 하방으로 냉기가 역류하는 것을 막을 수 있게 된다. 또한 송풍팬(8)의 최저회전수로 구동시키는 것에 의하여, 정상적인 회전수로 구동되는 경우 발생하는 냉동실(4)의 냉기가 냉장실(2)로 공급되어 냉장실(4)이 과냉되는 것을 막을 수 있다.By configuring the blower fan 8 to rotate at the minimum rotational speed in the state where the compressor 7 is stopped, the cold air flows backward from the upper refrigerating chamber 2 through the refrigerating chamber duct 3 to prevent it from flowing backward. It becomes possible. In addition, by driving at the lowest rotational speed of the blower fan 8, the cold air of the freezer compartment 4 generated when the normal rotational speed is driven can be supplied to the refrigerating chamber 2 to prevent the refrigerating chamber 4 from being overcooled. .
본 발명에 의하면 상기와 같이 댐퍼(9)가 열린 상태에서 압축기(7)의 구동이 정지되면, 송풍팬(8)의 회전수를 제어하는 것에 의하여 냉기의 역류 및 냉장실의 과냉을 방지할 수 있는 것을 기술적 요지로 하고 있음을 알 수 있다.According to the present invention, when the drive of the compressor 7 is stopped while the damper 9 is open as described above, by controlling the rotation speed of the blower fan 8, it is possible to prevent backflow of cold air and subcooling of the refrigerating compartment. It can be seen that the technical point.
그리고 압축기(7)의 구동이 정지된 후, 최저회전수로 구동되는 상기 송풍팬(8)은, 지속적으로 구동되는 것도 가능하지만 일정시간 구동하는 것이 바람직하다. 이렇게 일정시간 구동하는 것에 의하여, 냉장실(2)의 과냉을 방지할 수 있을 것이다. 이러한 일정시간의 구동여부는, 송풍팬을 구동하는 모터의 특성과 냉장고의 전체적인 시스템의 여건에 따라 결정될 것이다.After the driving of the compressor 7 is stopped, the blowing fan 8 driven at the lowest rotational speed may be continuously driven, but it is preferable to drive the blower fan for a predetermined time. By driving for a predetermined time in this way, it is possible to prevent overcooling of the refrigerating chamber 2. Whether or not the driving time is determined by the characteristics of the motor driving the blowing fan and the overall system of the refrigerator.
이상에서 살펴본 바와 같이, 본 발명에 의하면 냉장고의 압축기가 정지된 상태에 있어서, 상부에 있는 냉장실(2)로 냉기를 공급하는 댐퍼(9)가 열린 상태라면, 냉장실의 냉기가 역류하여 하부의 냉동실로 내려오는 것을 방지하기 위하여 최저회전수로 송풍팬을 회전시키는 것을 기본적인 기술사상으로 하고 있음을 알 수 있다.As described above, according to the present invention, when the compressor of the refrigerator is stopped, and the damper 9 for supplying cold air to the refrigerating compartment 2 in the upper portion is opened, the cold air of the refrigerating compartment flows backward so that the freezer compartment in the lower part is reversed. It can be seen that the basic technical idea is to rotate the blower fan at the lowest rotational speed in order to prevent it from coming down.
이상과 같은 본 발명에 의하면, 상기 송풍팬을 최저회전수로 동작시키는 것에 의하여, 상부의 냉장실(2)에서 하부의 냉동실(4)로 냉기가 내려오는 것을 방지할 수 있을 것이다. 또한 이와 동시에 송풍팬(8)을 정상적인 속도로 구동하는 경우 발생하는 냉장실의 과냉을 방지할 수 있게 되는 효과를 기대할 수 있다. 따라서 본 발명에 의하면, 냉장고의 냉동실의 온도변화를 적게함과 동시에 과냉을 방지할 수 있게 될 것이다.According to the present invention as described above, by operating the blower fan at the minimum rotational speed, it is possible to prevent the cold air comes down from the upper refrigerating chamber (2) to the lower freezing chamber (4). At the same time, it is possible to expect the effect of preventing the overcooling of the refrigerating chamber generated when the blower fan 8 is driven at a normal speed. Therefore, according to the present invention, it will be possible to reduce the temperature change of the freezer compartment of the refrigerator and at the same time prevent overcooling.
또한 냉기의 공급시간 동안 저온상태로 냉각된 댐퍼에, 상대적으로 고온상태의 냉장실 냉기가 접촉하는 것에 의하여 발생하는 댐퍼의 결빙현상을 방지할 수 있게 되어 냉장고의 신뢰성을 확보할 수 있게 된다.In addition, it is possible to prevent the freezing phenomenon of the damper caused by the contact of the damper cooled to a low temperature state during the supply time of the cold air to the relatively high temperature of the refrigerator compartment to ensure the reliability of the refrigerator.
