냉장고의 냉기조절장치 제어방법How to control cold air conditioner of refrigerator

본 발명은 냉장고의 냉기조절장치 제어방법에 관한 것으로, 특히 냉장고의 온도를 조절하는데 있어서 정상 운전시에는 냉기조절장치 내의 냉기차단막(복수개)을 동시에 전개 또는 전폐하고, 고내 한 선반내에 식품부하가 집중되어 투입되었을 경우는 그 온도를 온도감지센서로 하여금 감지하게 하여 감지된 부분의 냉기차단막만을 전개하여 집중냉각을 하는 냉장고의 냉기조절장치 제어방법에 관한 것이다.The present invention relates to a method for controlling a cold air conditioner of a refrigerator, and in particular, in controlling the temperature of a refrigerator, during normal operation, the cold air barriers (multiple) in the cold air conditioner are simultaneously developed or closed, and food load is concentrated in a shelf in the refrigerator. And a temperature sensor to detect the temperature thereof, and to control the cold air conditioner of the refrigerator by intensive cooling by developing only the cold air blocking film of the detected portion.

도 1은 종래 냉장고의 일예를 개략적으로 보인 정면도이고, 도 2는 도 1에서냉기 조절장치의 구성을 보인 측면도로서, 이에 도시된 바와 같이 냉장실에는 냉장실의 온도를 감지하여 온도를 제어하는 온도감지센서가 냉장실의 좌,우 또는 뒷벽에 부착되어 있으며, 대개의 경우는 1개의 냉기차단막(Baffle)을 가진 냉기조절장치(Damper)(1)로 냉장실 전체에 냉기를 공급하나, 필요에 따라서는 도 2에서와 같이 2개의 냉기차단막(10)(11)을 가진 냉기조절장치로 중칸과 하칸의 측벽에 온도감지센서(s1),(s2)를 부착하여, 각각의 온도감지센서(S1)(S2)로 각 냉기조절장치의 냉기차단막을 제어하여 중칸과 하칸의 온도를 제어한다.Figure 1 is a front view schematically showing an example of a conventional refrigerator, Figure 2 is a side view showing the configuration of the cold air conditioner in Figure 1, as shown in the refrigerating chamber temperature sensing sensor for controlling the temperature by sensing the temperature of the refrigerator compartment Is attached to the left, right or rear wall of the refrigerating compartment, and in most cases, cold air is supplied to the entire refrigerating compartment by a damper (1) having one baffle, but, if necessary, FIG. As in the cold air conditioner having two cold air blocking membranes (10, 11) by attaching the temperature sensor (s1), (s2) on the side walls of the middle compartment and the lower compartment, respectively, each temperature sensor (S1) (S2) By controlling the cold air blocking membrane of each cold air conditioner to control the temperature of the middle compartment and the lower compartment.

상기와 같이 구성된 종래 장치의 동작 과정을 도 3을 참조하며 설명하면 다음과 같다.An operation process of the conventional apparatus configured as described above will be described with reference to FIG. 3.

도 3은 종래 냉장고의 동작 흐름도로서, 이에 도시된 바와 같이 압축기(미도시)와 팬 모터(미도시)를 구동시키고, 제1,2 냉기차단막(10)(11)을 전개한 후, 제1 온도 감지센서(S1)에서 감지한 온도(R1)가 설정온도(T1)에 도달하였는지를 판단하고, 이 판단에 따라 도달하였으면 제1 냉기차단막(10)을 전폐한 다음 제2 온도감지센서(S2)에서 감지한 은도(R2)가 설정온도(T2)에 도달하였는지를 판단하며, 이 판단결과 도달하였으면 제2 냉기차단막(11)을 전폐한 후, 현재 냉동실 온도가 설정된 냉동실 온도(보통 -18℃)에 도달하였는지를 판단하여 도달하였으면 상기 압축기와 냉동 팬의 구동을 정지한 후, 정상적인 운전으로 복귀한다.3 is an operation flowchart of a conventional refrigerator, and as shown therein, a compressor (not shown) and a fan motor (not shown) are driven, and the first and second cold air blocking membranes 10 and 11 are developed, and then the first It is determined whether the temperature R1 sensed by the temperature sensor S1 has reached the set temperature T1. If the temperature R1 reaches the set temperature T1, if the temperature R1 reaches the set temperature T1, the first cold air blocking film 10 is closed and then the second temperature sensor S2 is closed. Determining whether the silver (R2) detected in the has reached the set temperature (T2), and if the determination result is reached, after closing the second cold air blocking membrane (11), the current freezer compartment temperature is set to the freezer compartment temperature (usually -18 ℃) After determining whether it has reached, if it has reached, it stops driving the compressor and the refrigeration fan, and then returns to normal operation.

상기와 같이 종래의 기술에 있어서는 2 개의 냉기차단막을 각각 제어할 때 센서감도의 오차 및 고내 냉기처짐의 영향으로 센서사이의 온도차가 발생한다. 즉하칸에 부착된 센서는 정상적으로 감지하여 냉기차단막을 전폐/전개시키나, 중칸에 부착된 센서는 냉동실에서 쳐져내려오는 냉기의 영향으로 항상 감지온도가 설정치 이하로 유지하고 있어 하칸쪽의 센서가 2∼3회 정상동작시 1회정도 감지하여 냉기차단막을 전개/전폐함으로써, 이 냉기차단막에 의해 냉기가 공급되는 칸(예 : 싱싱실)의 고내 온도가 상승하여 설정온도보다 높은 온도를 유지하여 그 칸의 온도편차가 심하여(예를 들어 냉기차단막이 전개되어 냉기가 토출 될 때는 0℃이하로 내려가고, 냉기차단막이 전폐되어 있는 동안에는 약 4∼5℃정도를 유지함으로써, 냉장실 설정온도 3℃보다 낮거나 높아진다) 약냉 및 과냉에 의해 식품보관에 악영향을 미치는 문제점이 있었다.As described above, in the related art, a temperature difference occurs between the sensors due to the error of sensor sensitivity and the influence of high cold air deflection when controlling two cold air blocking films, respectively. In other words, the sensor attached to the lower compartment normally detects and opens / closes the cold air barrier, but the sensor attached to the central compartment is always kept below the set value due to the cold air coming out of the freezer compartment. In the normal operation of 3 times, it detects about 1 time and develops / closes the cold air barrier, so that the inside temperature of the compartment (for example, fresh room) where cold air is supplied by the cold air barrier increases, and maintains the temperature higher than the set temperature. Temperature difference is too low (for example, when the cold air barrier is developed and the cold air is discharged, the temperature is lowered below 0 ° C., while the cold air barrier is fully closed, the temperature is kept below 4 ° C. There is a problem that adversely affects food storage by mild cooling and subcooling.

따라서, 본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 창안한 것으로, 정상 운전시에는 냉기조절장치 내의 냉기차단막(복수개)을 동시에 전개 또는 전폐하고, 고내 한 선반내에 식품부하가 집중되어 투입되었을 경우는 그 온도를 온도감지센서로 하여금 감지하게 하여 감지된 부분의 냉기차단막만을 전개하여 집중냉각을 하는 방법을 제공함에 그 목적이 있다.Therefore, the present invention was devised to solve the above-described conventional problems, and during normal operation, the cold air blocking membrane (multiple) in the cold air conditioner was simultaneously developed or closed, and the food load was concentrated in one shelf. In this case, the purpose of the present invention is to provide a method of intensive cooling by deploying only the cold air blocking film of the detected part by causing the temperature sensor to sense the temperature.
