Description

냉기조절장치의 결빙방지방법How to prevent freezing of cold air conditioner

본 발명은 냉기조절장치의 결빙방지방법에 관한 것으로, 특히 냉장고에 있어서 주위 온도가 고온이고, 습도가 높을때나 고온고습의 식품부하를 고내에 투입하였을 때 온도차에 의하여 댐퍼 표면에 습기가 부착되어 운전시 결빙됨으로써, 발생하는 댐퍼의 오동작 및 과냉 현상을 방지하는 냉기조절장치의 결빙방지방법에 관한 것이다.The present invention relates to a method for preventing freezing of a cold air conditioner, and particularly, in a refrigerator, when the ambient temperature is high, when humidity is high, or when a food load of high temperature and high humidity is introduced into the inside of the refrigerator, moisture is attached to the surface of the damper due to the temperature difference. By freezing during operation, the present invention relates to a method for preventing freezing of a cold air conditioner that prevents malfunction and overcooling of a damper.

도 1은 종래 냉장고의 일예를 개략적으로 보인 정면도이고, 도 2는 도 1에서 냉기조절장치의 구성을 보인 측면도로서, 이에 도시된 바와 같이 냉장실에는 냉장실의 온도를 감지하여 온도를 제어하는 온도감지센서(S1, S2)가 냉장실의 좌,우 또는 뒷벽에 부착되어 있으며, 대개의 경우는 1개의 냉기차단막(Baffle)을 가진 냉기조절장치(Damper, 2)로 냉장실 전체에 냉기를 공급하나, 필요에 따라서는 2개의 냉기차단막을 가진 냉기조절장치로 중칸과 하칸의 측벽에 온도감지센서를 부착하여 각각의 온도감지센서로 각 냉기조절장치의 냉기차단막을 제어하여 중칸과 하칸의 온도를 제어한다.1 is a front view schematically showing an example of a conventional refrigerator, and FIG. 2 is a side view showing the configuration of a cold air conditioner in FIG. 1, and as shown therein, a temperature sensing sensor controlling a temperature by sensing a temperature of a refrigerating compartment. (S1, S2) are attached to the left, right or rear wall of the refrigerating compartment, and in most cases, a cold air conditioner (Damper 2) having one baffle to supply cold air to the entire refrigerating compartment. Therefore, a cold air conditioner having two cold air blocking membranes is attached to the side walls of the middle compartment and the lower compartment, and a temperature sensor is attached to each side of the cold air control unit to control the temperature of the middle compartment and the lower compartment.

냉장실의 온도가 설정된 온도(보통 3℃)에 도달하여 냉장고의 운전이 정지하였을 때 냉장실에 고온고습의 식품부하를 투입하거나, 냉장실의 사용이 빈번한 여름철에 고온고습의 외기가 냉장실 문을 열었을 때 냉장실로 유입되어 고내의 온도차에 의해 고내온도보다 항상 상대적으로 낮은 냉기차단막의 표면이나 주위 구조물에 착상하여 물방울이 형성되고, 냉장고의 운전이 개시되어 저온(보통 18℃)의 냉기가 토출되면 얼음으로 성장하여 결빙이 발생한다.When the temperature of the fridge reaches the set temperature (usually 3 ° C) and the operation of the refrigerator is stopped, the food compartment is placed at a high temperature and high humidity in the fridge, or when the outside of the fridge opens the fridge door in the summer when the fridge is frequently used. Water droplets are formed on the surface or surrounding structure of the cold air barrier membrane, which is relatively lower than the internal temperature, due to the temperature difference in the air, and grows on ice when cold air is discharged at low temperature (usually 18 ° C). Freezing occurs.

결빙이 발생하는 원인은 도 3에 도시된 바와 같이 대개 냉장실의 온도만족시간과 냉동실의 온도만족시간이 서로 다르기 때문에 발생되는데, 압축기(미도시)와 냉동 팬(1)이 구동되고, 냉기조절장치(2)의 냉기차단막이 전개되면 냉장실의 온도가 설정온도(보통 3℃)에 도달하였는지를 판단하며, 통상 냉장실의 온도가 설정온도에 도달하는 것이 빠르며, 이 때문에 냉장실의 온도가 만족되면 냉기차단막이 전폐되어 냉장실로 토출되던 냉기가 차단하고, 냉동실의 온도를 만족시키기 위해 냉장고가 운전하는 동안 저온의 냉기가 냉기차단막을 지속적으로 냉각시켜 상기 냉기차단막의 표면 및 주위의 온도를 저온으로 유지시킨다(냉기가 정체되어 있어 유동이 없기 때문).The cause of freezing is usually caused by the temperature satisfaction time of the refrigerating compartment and the temperature satisfaction time of the freezer compartment as shown in FIG. 3, the compressor (not shown) and the refrigeration fan (1) is driven, the cold air conditioner When the cold air barrier of (2) is developed, it is determined whether the temperature of the refrigerating compartment has reached the set temperature (usually 3 ° C), and it is usually faster for the temperature of the refrigerating compartment to reach the set temperature. The cold air that has been shut off and discharged to the refrigerating chamber is cut off, and low temperature cold air continuously cools the cold air blocking membrane while the refrigerator is operating to satisfy the temperature of the freezing chamber, thereby keeping the surface and surrounding temperature of the cold blocking film at a low temperature. Is stagnant and there is no flow).

상기와 같이 종래의 기술에 있어서는 도4에 도시된 바와 같이 냉장실의 온도가 설정된 온도(보통 3℃)에 도달하여 냉장고의 운전이 정지하였을 때 냉장실에 고온고습의 식품부하를 투입하거나, 냉장실의 사용이 빈번한 여름철에 고온고습의 외기가 냉장실 문을 열었을 때 냉장실로 유입되어 고내의 온도차에 의해 고내온도보다 항상 상대적으로 낮은 냉기차단막의 표면이나 주위 구조물에 착상하여 물방울이 형성됨으로써, 냉장고의 운전이 개시되어 저온의 냉기가 토출되면 얼음으로 결빙되어 냉장실로 토출되는 냉기가 제어되지 못해 고내의 온도가 저온으로 내려가 식품부하가 과냉되고, 또한 이를 해결하기는 위하여 히터를 부착함으로써, 그 만큼의 원가가 상승하는 문제점이 있었다.As described above, in the related art, when the temperature of the refrigerator compartment reaches a set temperature (usually 3 ° C.) as shown in FIG. 4 and the operation of the refrigerator is stopped, a food load of high temperature and high humidity is put into the refrigerator compartment or the use of the refrigerator compartment. During the frequent summer season, when the outdoor air of high temperature and high humidity opens the refrigerating compartment door, water droplets are formed on the surface or surrounding structure of the cold air blocking membrane which is relatively lower than the internal temperature due to the temperature difference in the high temperature, and thus the operation of the refrigerator starts. When low temperature cold air is discharged, the freezing air discharged into the refrigerating chamber cannot be controlled due to freezing of ice, and the temperature inside the high temperature drops to low temperature, and the food load is supercooled. There was a problem.

따라서, 본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 창안한 것으로, 냉장고의 운전이 정지하였을 때 냉장실에 고온고습의 식품부하를 투입하거나, 냉장실의 사용이 빈번한 여름철에 고온고습의 외기가 냉장실로 유입되면 이를 온도감지센서가 감지하게 하고, 이 감지한 온도와 냉장실 문의 개폐전의 온도차가 설정온도차 이상인 경우 냉동 팬을 구동시켜 냉기를 토출하게 함으로써, 유로내 냉기유동을 주어 온도차에 의한 냉기차단막의 결빙을 방지하는 방법을 제공함에 그 목적이 있다.Therefore, the present invention was devised to solve the above-mentioned conventional problems, and when the operation of the refrigerator is stopped, the food load of high temperature and high humidity is put into the refrigerating chamber, or the outdoor air of high temperature and high humidity is used in the summer season when the refrigerator is frequently used. If the temperature sensor is detected, the temperature sensor detects this and if the detected temperature and the temperature difference before opening / closing the refrigerating compartment door are higher than the set temperature difference, the refrigeration fan is driven to discharge the cold air. Its purpose is to provide a method for preventing freezing.

이와 같은 목적을 달성하기 위한 본 발명은, 냉장고의 냉기조절방법에 있어서, 냉장고의 운전이 정지하였을 때 냉기차단막을 전개시키고, 냉장실 문의 개폐전후의 온도차가 설정온도차 이상인 경우 냉동 팬을 구동시켜 냉기를 토출하게 함으로써, 유로내 냉기유동을 주는 것을 특징으로 한다.In order to achieve the above object, the present invention provides a method for adjusting the cold air of a refrigerator, wherein when the operation of the refrigerator is stopped, a cold air blocking membrane is developed, and when the temperature difference between the opening and closing of the refrigerating compartment door is greater than or equal to the set temperature difference, the refrigeration fan is driven. By discharging, it is characterized by giving cold air flow in the flow path.

이하, 본 발명에 따른 실시예를 첨부한 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도5는 본 발명을 적용한 동작 흐름도로서, 이에 도시한 바와 같이 냉동실 및 냉장실의 온도가 설정온도(보통 냉동실은 -18℃, 냉장실은 3℃)에 도달하지 못하면 냉장고(압축기와 냉동 팬을 구동하고, 냉기차단막을 전개)를 운전하며, 냉장실의 온도가 설정온도에 도달하면 냉기차단막을 전폐하고, 냉동실의 온도가 설정한 온도에 도달할때까지 압축기와 냉동 팬(1)을 계속 구동하다가 설정한 온도에 도달하면 상기 압축기와 냉동 팬(1)의 구동을 정지시킨다.5 is an operation flowchart to which the present invention is applied. As shown in FIG. 5, when the temperature of the freezer compartment and the refrigerating chamber does not reach the set temperature (usually -18 ° C in the freezer compartment and 3 ° C in the freezer compartment), the refrigerator (the compressor and the freezing fan is driven). When the temperature of the fridge reaches the set temperature, the cold air barrier is closed and the compressor and the refrigeration fan (1) continue to be driven until the freezer temperature reaches the set temperature. When the temperature is reached, the drive of the compressor and the refrigeration fan 1 is stopped.

냉장고의 운전이 정지하면 냉장실로 토출되는 냉기를 차단하고 있던 냉기차단막이 전개되고, 그때까지 냉기차단막에 의해 정체되어 있던 냉기를 아래 부분으로 흘려보내 냉기차단막의 온도를 고내온도 만큼 높힌다. 만일 이때(냉장고의 운전을 정지하고 있을 때) 냉장고에 식품의 투입과 인출이 발생하면 온도감지센서가 이를 감지하여 문의 개폐전후의 온도차가 설정온도차 이상이면 냉동 팬(1)을 구동하여 냉기를 토출시켜 유로내 냉기유동을 주며, 냉장고가 다시 운전을 시작하면 정상적인 운전조건으로 돌아간다.When the operation of the refrigerator stops, a cold air blocking film that blocks the cold air discharged into the refrigerating chamber is developed, and the cold air that has been stagnated by the cold air blocking film is flowed to the lower portion to raise the temperature of the cold air blocking film by the internal temperature. If at this time (while the operation of the refrigerator is stopped), food input and withdrawal occurs in the refrigerator, and the temperature sensor detects this and if the temperature difference before and after opening and closing the door is more than the set temperature difference, the refrigeration fan 1 is driven to discharge cold air. It gives cold air flow in the flow path, and it returns to normal operation condition when the refrigerator starts to operate again.

이상에서 설명한 바와 같이 본 발명 냉기조절장치의 결빙방지방법은 냉장고의 운전을 정지하고 있을 때 발생하는 고내 온도차에 의한 냉기차단막의 결빙을 방지하고, 또한 히터를 사용하지 않으므로 원가의 상승을 억제하는 효과가 있다.As described above, the method of preventing freezing of the air conditioner of the present invention prevents the freezing of the cold air blocking membrane due to the difference in temperature generated when the refrigerator is stopped, and also suppresses the increase in cost since no heater is used. There is.
