냉장고는 냉동싸이클에 의하여 생성된 냉기로 저장실을 냉각시켜 냉동식품이 냉장식품을 저장보관하는 것으로, 제1도는 이러한 냉장고의 냉기토출구를 보인 냉장고의 정면구성이다. 이에 도시한 바와 같이, 본체케이스(1)의 내부에는 냉동실(2)과 냉장실(3)이 설치되고, 냉동실(2)의 후방에는 냉기를 생성하는 증발기(4)가 설치된다. 증발기 (4)의 상부에는 증발기(4)에서 생성된 냉기를 강제송풍하는 팬(5)이 설치되고, 냉동실(2)과 냉장실(3)의 후방에는 팬(5)에 의하여 송풍되는 냉기를 냉동실(2)과 냉장실(3)로 안내하는 덕트(6)가 설치되고, 덕트(6)에는 다수개의 냉기토출구(7)가 형성되어 덕트(6)를 유동하는 냉기가 냉동실(2)과 냉장실(3)로 토출되어 열교환하여 냉동실(2)과 냉장실(3)을 냉각하도록 한다.The refrigerator cools the storage compartment by the cool air generated by the refrigeration cycle, and the frozen food stores and stores the refrigerated food.

그러나 이와 같은 종래 냉장고의 냉기토출구조는 냉기의 토출방향이 고정되어 있는 관계로 저장실의 냉각부하가 편차질 경우에 이를 빠르고 효율적으로 냉각할 수 없는 문제가 있었다. 즉, 냉장실의 우측이나 좌측에 상태적으로 고온인 식품이 담긴 용기가 수납될 경우 수납된 용기로 냉기를 집중토출시켜 수납된 식품을 적정한 온도로 빠르게 냉각시킬 수 없어 냉기를 장시간 토출시켜 수납된 식품을 냉각시킴으로써 냉장고의 운전효율이 떨어지는 문제와 냉장실에 함께 수납된 다른 식품이 과냉각되는 문제가 있었다.However, since the cold air discharge structure of the conventional refrigerator has a fixed discharge direction of cold air, there is a problem that it can not be cooled quickly and efficiently when the cooling load of the storage compartment deviates. That is, when a container containing foodstuffs of high temperature is housed in the right or left side of the refrigerating compartment, the refrigerated food is concentrated and discharged into the container so that the stored food can not be rapidly cooled to a proper temperature. There is a problem that the operation efficiency of the refrigerator is lowered by cooling the refrigerating compartment, and that other food stored in the refrigerating compartment is overcooled.
따라서 본 발명은 상기한 문제를 해결하기 위한 것으로, 본 발명의 목적은 저장실내의 온도 편차에 상응하게 냉기의 토출방향을 제어함으로써 냉각효율을 향상시킬 수 있는 냉장고의 냉기 토출방향 제어방법을 제공하는 것이다. 본 발명의 다른 목적은 토출되는 냉기를 골고루 분산시킴으로써 냉기의 열교환효율을 향상시킬 수 있는 냉장고의 냉기 토출방향 제어방법을 제공하는 것이다.SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a cold air discharge direction control method for a refrigerator which can improve cooling efficiency by controlling a discharge direction of cold air in accordance with a temperature variation in a storage room will be. Another object of the present invention is to provide a cold air discharge direction control method for a refrigerator which can improve the heat exchange efficiency of cold air by uniformly distributing cold air to be discharged.

이하에서는 첨부도면을 참조하여 본 발명의 바람직한 실시예를 상세하게 설명하겠다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도2는 본 발명이 적용되는 냉장고의 정면구성도이고, 도3은 측단면도이다. 이에 도시한 바와 같이, 본체케이스(10)의 내부에는 전면이 개구된 저장실(11)이 설치되는데, 이 저장실(11)은 중간격(12)에 의하여 냉동실(11a)과 냉장실(11b)로 상하 구획되며, 이들의 전면에는 도어(13)가 설치되어 개폐할 수 있도록 한다. 냉동실(11a)의 후방에는 냉기를 생성하는 증발기(21)가 배치되고, 증발기(21)의 상부에는 생성된 냉기를 강제송풍하는 송풍팬(22)이 설치되며, 냉동실(11a)과 냉장실(11b)의 후방에는 송풍되는 냉기를 냉동실(11a)과 냉장실(11b)로 적절히 안내하기 위한 덕트(23)가 설치된다. 중간격(12)에는 냉동실(11a)과 냉장(11b)의 냉기를 증발기(21)로 복귀시키기 위한 복귀덕트(24)가 설치된다. 덕트(23)에는 다수개의 냉기토출구(25)가 형성되어 냉장실(11b) 및 냉동실(11a)과 덕트(23)를 연통시키는데, 냉장실 (11b)에 형성된 냉기토출구(25) 각각에는 팬(30)이 설치되어 냉기의 토출방향을 조정한다. 팬(30)은 덕트(23)의 내부에 입설된 회전축(41)에 일체로 결합되며, 회전축(41)의 하단은 모터(42)에 연결된다. 모터 (42)는 그 회전수를 가변할 수 있는 것이 설치되며, 냉장실(11b)의 좌우 양측벽에는 저장실의 온도를 감지하는 센서(S1)(S2)가 각각 설치된다.FIG. 2 is a front view of a refrigerator to which the present invention is applied, and FIG. 3 is a side sectional view. As shown in the drawing, a storage compartment 11 having a front opened is installed in the body case 10. The storage compartment 11 is divided into a freezing compartment 11a and a refrigerating compartment 11b by a middle compartment 12, And a door 13 is provided on the front surface of the door so that the door 13 can be opened and closed. An evaporator 21 for generating cold air is disposed in the rear of the freezing chamber 11a and a blowing fan 22 for forcibly blowing the generated cold air is provided in the upper portion of the evaporator 21. The freezing chamber 11a and the refrigerating chamber 11b Is provided with a duct 23 for appropriately guiding blowing cold air to the freezing chamber 11a and the refrigerating chamber 11b. The intermediate compartment 12 is provided with a freezing chamber 11a and a return duct 24 for returning the cold air of the refrigerating chamber 11b to the evaporator 21. A plurality of cold air discharge openings 25 are formed in the duct 23 to communicate the refrigerating chamber 11b and the freezing chamber 11a with the duct 23. A fan 30 is installed in each of the cold air discharge openings 25 formed in the refrigerating chamber 11b. To adjust the discharge direction of the cold air. The fan 30 is integrally coupled to a rotary shaft 41 installed inside the duct 23 and the lower end of the rotary shaft 41 is connected to the motor 42. The motor 42 is provided with a variable number of rotations and sensors S 1 and S 2 for detecting the temperature of the storage compartment are installed on both left and right side walls of the refrigerating compartment 11b.
그리고 팬(30)은 도4에 도시한 바와 같이, 내측에서 외측으로 갈수록 회전방향의 반대측으로 경사진 다수개의 깃(31)을 포함하여 팬(30)의 회전수가 저속일 때에는 냉기가 회전방향의 반대측으로 토출되도록 한다. 즉, 팬(30)을 통하여 냉장실로 토출되는 냉기의 토출방향을 가장 큰 인자는 깃에 의하여 팬(30)의 회전방향 반대측으로 향하는 힘(k2)과 팬(30)의 회전속도에 의한 원주속도(k1)이다. 냉기의 실제토출방향(K)은 상기한 힘의 합성으로 결정되는데, 팬(30)의 회전방향 반대방향을 향하는 힘(k2)은 고정값이고, 원주속도(K1)는 가변가능한 모터(42)의 회전속도에 비례하는 값이다. 따라서 본 발명에서는 팬(30)의 회전속도를 가변시켜 원주속도를 가변시켜 냉기의 토출방향 (K)을 조정하는 것이다.As shown in FIG. 4, the fan 30 includes a plurality of vanes 31 that are inclined to the opposite side of the rotation direction from the inside to the outside, so that when the number of revolutions of the fan 30 is low, To be discharged to the opposite side. That is, the greatest factor in the discharge direction of the cold air discharged into the refrigerating chamber through the fan 30 is the force (k 2 ) directed toward the opposite side in the rotating direction of the fan (30) Is the speed (k 1 ). The actual discharge direction K of the cold air is determined by the combination of the above forces. The force k 2 directed in the direction opposite to the rotating direction of the fan 30 is a fixed value, and the peripheral velocity K 1 is a variable 42). Therefore, in the present invention, the rotational speed of the fan 30 is varied to vary the circumferential speed to adjust the discharge direction K of the cool air.
도5에 도시한 순서도를 참조하여 본 발명에 따른 냉기 토출방향의 제어방법을 상세하게 설명하겠다. 이에 도시한 바와 같이, 센서(S1)(S2)에서 감지된 온도값을 비교하여 온도가 상대적으로 높은 측을 감지하는 단계와 팬(30)의 회전속도를 조정하여 냉기를 온도가 높은 측으로 토출시키는 단계를 포함한다. 이를 상세하게 설명하면, 각각의 센서(S1)(S2)에서 감지한 온도들 간의 차이가 소정 기준값보다 작으면 저장실(11)내의 온도편차 없으므로 팬(30)의 회전속도를 일정하게 유지시킨다. 만약 팬(30)의 회전방향측에 있는 센서(S1)에서 감지한 온도가 반대측에 센서(S2)에서 감지한 온도보다 기준값 이상 높을 경우에는 팬30의 회전수를 증가시켜 원주속도를 키워 냉기의 토출방향을 팬(30)의 회전방향측으로 집중시킨다. 그리고 팬(30)의 회전방향측에 있는 센서(S1)에서 감지한 온도가 반대측에 센서(S2)에서 감지한 온도보다 기준값보다 낮은 경우에는 팬(30)의 회전수를 감소시켜 원주속도를 줄여 냉기의 토출방향을 팬(30)의 회전방향 반대측으로 집중시킨다.The control method of the cool air discharge direction according to the present invention will be described in detail with reference to the flowchart shown in FIG. As shown in the figure, the temperature sensed by the sensors S 1 and S 2 is compared with each other to detect a relatively high temperature side, and the rotational speed of the fan 30 is adjusted, And discharging it. If the difference between the temperatures sensed by the sensors S 1 and S 2 is smaller than the predetermined reference value, the temperature of the storage chamber 11 is not varied. Therefore, the rotation speed of the fan 30 is kept constant . If the temperature sensed by the sensor S 1 on the rotation direction side of the fan 30 is higher than the reference value by the temperature sensed by the sensor S 2 on the opposite side, the rotation speed of the fan 30 is increased to increase the peripheral speed Thereby concentrating the discharge direction of the cool air toward the rotation direction side of the fan (30). When the temperature sensed by the sensor S 1 on the rotational direction side of the fan 30 is lower than the reference value sensed by the sensor S 2 on the opposite side, the number of revolutions of the fan 30 is decreased, To concentrate the discharge direction of the cool air toward the opposite side of the rotation direction of the fan (30).
이상에서 상세하게 설명한 바와 같이, 본 발명에 따른 냉장고의 냉기 토출방향 제어방법은 냉장실내의 온도편차에 따라 냉기의 토출방향을 조정하여 냉기를 온도가 높은부위측으로 집중적으로 토출시킴으로써 냉각효율을 향상시킬 수 있으며, 냉기의 토출량을 증가시킬 수 있는 이점이 있다.As described above in detail, the method for controlling the cooling / discharging direction of the refrigerator according to the present invention improves the cooling efficiency by intensively discharging the cold air toward the high temperature side by adjusting the discharging direction of the cold air according to the temperature deviation of the refrigerating chamber There is an advantage that the discharge amount of cold air can be increased.
