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, such a cold air discharging structure of the conventional refrigerator has a problem that it cannot be cooled quickly and efficiently when the cooling load of the storage compartment is varied because the discharge direction of the cold air is fixed.

이하에서는 첨부도면을 참조하여 본 발명의 바람직한 실시예를 상세하게 설명하겠다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.
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 냉장실(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.Figure 2 is a front configuration diagram of a refrigerator to which the present invention is applied, Figure 3 is a side cross-sectional view. As shown in the figure, a storage chamber 11 having a front surface is installed inside the main body case 10, which is spaced up and down into the freezing chamber 11a and the refrigerating chamber 11b by the intermediate space 12. Compartment, the front of these doors 13 are installed to be opened and closed. An evaporator 21 for generating cold air is disposed at the rear of the freezer compartment 11a, and a blowing fan 22 for forcedly blowing the generated cold air is installed at the upper part of the evaporator 21, and the freezer compartment 11a and the refrigerating compartment 11b are provided. At the rear of the), a duct 23 for guiding the cool air to be blown into the freezing chamber 11a and the refrigerating chamber 11b is provided. The intermediate space 12 is provided with a return duct 24 for returning the cold air of the freezing chamber 11a and the refrigerating chamber 11b to the evaporator 21. A plurality of cold air outlets 25 are formed in the duct 23 to communicate the refrigerating chamber 11b and the freezer compartment 11a with the duct 23. Each of the cold air discharge ports 25 formed in the refrigerating chamber 11b includes a fan 30. This is provided to adjust the discharge direction of cold air. The fan 30 is integrally coupled to the rotary shaft 41 placed inside the duct 23, and the lower end of the rotary shaft 41 is connected to the motor 42. The motor 42 is provided to be able to vary the number of revolutions, and the sensor (S1) (S2) for sensing the temperature of the storage compartment are respectively installed on the left and right side walls of the refrigerating chamber (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 inclined to the opposite side of the rotational direction from the inner side to the outer side, and when the rotation speed of the fan 30 is low, the cold air is in the rotational direction. Discharge to the opposite side. That is, the largest factor in the discharge direction of the cold air discharged into the refrigerating chamber through the fan 30 is the circumferential speed due to the force k2 directed to the opposite side to the rotational direction of the fan 30 by the feather and the rotational speed of the fan 30. (k1). The actual discharge direction K of the cold air is determined by the combination of the above-mentioned forces. The force k2 in the direction opposite to the rotational direction of the fan 30 is a fixed value, and the circumferential speed K1 is a variable motor 42. It is proportional to the rotation speed of. Therefore, in the present invention, the rotational speed of the fan 30 is varied to adjust the discharge direction K of the cold air by varying the circumferential speed.
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.Referring to the flowchart shown in Figure 5 will be described in detail the control method of the cold air discharge direction according to the present invention. As shown in the drawing, comparing the temperature values sensed by the sensors S1 and S2 to detect a relatively high temperature side and adjusting the rotational speed of the fan 30 to discharge cold air to the high temperature side. Steps. In detail, if the difference between the temperatures sensed by each of the sensors S1 and S2 is smaller than a predetermined reference value, there is no temperature deviation in the storage chamber 11, so that the rotation speed of the fan 30 is kept constant. If the temperature detected by the sensor S1 on the rotational side of the fan 30 is higher than the reference value detected by the sensor S2 on the opposite side, the rotation speed of the fan 30 is increased to increase the circumferential speed of the cold air. The discharge direction is concentrated to the rotation direction side of the fan 30. If the temperature detected by the sensor S1 on the rotational side of the fan 30 is lower than the reference value than the temperature detected by the sensor S2 on the opposite side, the rotation speed of the fan 30 is reduced to reduce the circumferential speed. The discharge direction of the cold air is concentrated on the side opposite to 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 in detail above, the method for controlling the cold air discharge direction of the refrigerator according to the present invention improves cooling efficiency by intensively discharging cold air to a portion having a high temperature by adjusting the discharge direction of cold air according to the temperature deviation in the refrigerator compartment. And, there is an advantage that can increase the discharge amount of cold air.
