Description

냉장실 칸 개별 냉각장치Refrigerator compartment individual chiller

한편, 나머지 냉기는 냉각기실(30) 후방 단열재(48) 내부에 형성된 메인덕트(42)를 따라 냉장실(R)로 이동되면서 냉기량 조절장치인 댐퍼(44)에 의하여 멀티틱트(46)를 통해 고내로 공급되는 냉기량이 조절되며, 고내로 공급된 냉기는 고내에 수납중인 식품을 냉장시킨 후에 사절부(50)에 형성된 냉기 리턴덕트(52b)를 타고 냉각기실 (30)로 귀환되어 냉동실(F)에서 귀환된 냉기와 혼합되면서 재차 상술한 냉기순환싸이클을 반복하고 있다.On the other hand, the remaining cold air is moved to the refrigerating chamber (R) along the main duct (42) formed inside the rear heat insulating material (48) of the cooler chamber (30) through the multi-tick (46) by the damper (44) which is a cold air volume control device. The amount of cold air supplied into the inside of the refrigerator is controlled, and the cold air supplied into the inside of the refrigerator is refrigerated, and the food is stored in the inside of the refrigerator. The cold air cycle is repeated again while mixing with the cold air returned from).

그런데, 이와 같은 냉기의 순환과정에서 특히 냉장실(R)의 냉기 순환의 경우에는 냉장실(R)을 선반(60)에 의해 다수의 공간으로 분리 구획되어 칸(55')을 이루고, 이러한 칸(55')에 저장되는 식품은 멀티덕트(46)를 통해 공급된 냉기가 자연대류에 의해 냉장실(R)을 냉각시키게 되므로, 냉장실 도어(80) 개폐후에 단시간에 고내 정온화가 힘들고, 또한 투입된 식품의 냉기 토출구로부터 멀리 보관되면 보관식품에 작용하는 냉각력이 약하고, 냉기토출구 근접위치에 보관되면 쉽게 빙결되어 버리는 등의 문제가 발생되었다.However, in the cold air circulation process, in the cold air circulation in the refrigerating compartment R, the refrigerating compartment R is divided into a plurality of spaces by the shelf 60 to form a compartment 55 ', and thus the compartment 55 is formed. The food stored in the ') is because the cold air supplied through the multi duct 46 cools the refrigerator compartment R by natural convection, so that the inside of the refrigerator compartment door 80 is hard to cool in a short time, and the cold air of the food is added. When stored away from the discharge port, the cooling power acting on the stored food is weak, and when stored near the cold air discharge port, such as freezing easily occurs.

본 발명은 상술한 바와 같은 제반 문제점을 감안하여 이를 해결하고자 창출된 것으로, 냉장고의 냉장실 고내를 단시간에 정온화시키면서 보관식품의 빙결을 방지하고 냉각성능을 향상시킬 수 있도록 냉장실 선반에 의해 구획된 각 칸마다 개별 냉각이 가능한 냉각장치의 제공을 그 기술적 과제로 하는 것이다.The present invention has been made in view of the above-mentioned problems, and is created to solve this problem, each compartment partitioned by the refrigerator compartment shelf to prevent freezing of the stored food and improve the cooling performance while allowing the inside of the refrigerator compartment to cool in a short time. The technical problem is to provide a cooling device capable of individually cooling each compartment.

이하에서는, 본 발명에 따라 선호된 일 실시예를 첨부도면을 참조하여 보다 상세하게 설명한다.Hereinafter, a preferred embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

도 2는 본 발명에 따라 선반 (60)에 의해 분리 구획되면서 밀폐된 냉장실(R)의 각 칸(55)을 보이는 냉장고의 측단면도로서, 냉장실(R)을 칸칸이 구획하는 각 선반(60)의 냉장실 전면쪽 단부에 횡방향으로 길게 고무부재(70)가 부착되어 냉장실 도어(80)의 도어포켓(88)에 면접 밀착되도록 되어 있다.2 is a side cross-sectional view of the refrigerator showing each compartment 55 of the refrigerating compartment R sealed while being separated and partitioned by the shelf 60 according to the present invention, and showing the compartments of each shelf 60 partitioning the refrigerator compartment R. FIG. The rubber member 70 is attached to the front end portion of the refrigerating compartment in the transverse direction so as to be in close contact with the door pocket 88 of the refrigerating compartment door 80.

그리고, 선반(60)에 의해 분리 구획된 각 칸(55)의 후방면인 내상(66)에는 제어부(미도시)와 전기적으로 연결된 온도센서(R1)(R2)(R3)가 부착되어 있다.In addition, temperature sensors R1, R2, and R3 electrically connected to a control unit (not shown) are attached to the inner box 66, which is a rear surface of each compartment 55 separated by the shelf 60.

또한, 냉장실 도어(80)은 그 내측에 충진되어 있는 단열재(48)를 그 하부에서 상부로 관통하여 냉기적트(90)가 형성되어 있고, 이 냉기덕트(90)는 냉장실 도어(80) 폐쇄시에는 사절부(50)에 형성된 냉장실 온기 리턴덕트(52b)와 냉기유로가 일치되어 연통되도록 형성되어 있다.In addition, the refrigerating compartment door 80 penetrates the heat insulating material 48 filled therein from the lower portion to the upper portion thereof, and a cold air drop 90 is formed, and the cold air duct 90 is closed when the refrigerating compartment door 80 is closed. The refrigerator compartment warm return duct 52b formed in the trimming section 50 and the cold air flow path are formed to communicate with each other.

아울러 상기 냉기덕트(90)에는 각 칸(55)들과 통할 수 있도록 통풍구(99)가 형성되고, 이 통풍구(99)에 다수의 흡입팬(92a)(92b)(92c)이 설치되며, 이 흡입팬(92a)(92b)(92c)은 각각 제어부에 전기적으로 연결되어 있다.In addition, the cold air duct 90 is formed with a ventilation hole 99 to communicate with each compartment 55, a plurality of suction fans (92a) (92b) (92c) is provided in the ventilation hole (99), The suction fans 92a, 92b and 92c are electrically connected to the control unit, respectively.

이러한 구성으로 이루어진 본 발명의 냉장실 칸 개별 냉각장치는, 선반(60)에 의해 구획된 각 칸(55)의 후면인 내상(66)에 부착된 온도센서(R1)(R2)(R3)에서 감지된 온도에 따라 제어부는 이를 비교판단하여 상기 온도센서(R1)(R2)(R3)에 대응되는 흡입팬(92a)(92b)(92c)을 구동시켜 해당 칸(55)의 온기가 냉기덕트(90)를 거쳐 리턴덕트(52b)를 통하여 냉각기실(10)로 귀환되도록 유도함으로서 따라서 멀티덕트(46)내의 냉기가 각 칸(55)으로 유입되어 해당 칸(55)을 냉각시키게 된다.The refrigerator compartment compartment individual cooling apparatus of this invention which consists of such a structure is sensed by the temperature sensor R1 (R2) (R3) attached to the inner case 66 which is the back of each compartment 55 partitioned by the shelf 60. According to the temperature, the control unit compares the driving temperature and drives the suction fans 92a, 92b, and 92c corresponding to the temperature sensors R1, R2, and R3. By returning to the cooler chamber 10 through the return duct 52b through the 90, the cool air in the multi-duct 46 flows into each compartment 55 to cool the corresponding compartment 55.

즉, 콤프레서(10)가 구동되어 냉매가 냉각싸이클을 따라 순환하면서 증발기(20)에서 냉기를 생성하면, 콤프레서(10)와 연동되는 송풍팬(32)에 의해 냉각기실(30)의 냉기가 해당 고내로 송풍된다.That is, when the compressor 10 is driven to generate cool air in the evaporator 20 while the refrigerant circulates along the cooling cycle, the cool air in the cooler chamber 30 is affected by the blower fan 32 interlocked with the compressor 10. It is blown into the room.

이때에, 냉기가 냉동실(F)로 공급되는 과정은 종래와 동일하게 진행되는 바, 냉동실(F)에 공급된 냉기는 사절부(50)에 형성된 리턴덕트(52a)를 통하여 귀환되며, 냉장실(R)에 공급된 냉기의 귀환은 부착된 온도센서(R1)(R2)(R3)에 의해 제어되는 흡입팬(92a)(92b)(92c)에 의하여 이루어진다.At this time, the process of supplying the cold air to the freezing compartment (F) proceeds in the same manner as the conventional bar, the cold air supplied to the freezing compartment (F) is returned through the return duct (52a) formed in the trimming section 50, the refrigerator compartment ( The return of the cold air supplied to R) is made by suction fans 92a, 92b and 92c controlled by the attached temperature sensors R1, R2 and R3.

즉, 냉장실(R)을 칸칸이 분리구획하는 선반(60)의 선단에 횡으로 고정된 고무부재(70)가 냉장실 도어(80)가 폐쇄되면 도어포켓(88)에 면접 밀착되어 각 선반(60)에 의해 분리된 공간들이 각각 독립적인 공간을 이루게 된다.That is, when the refrigerating chamber door 80 is closed, the rubber member 70 horizontally fixed to the front end of the shelf 60 in which the compartment separates the refrigerating compartment R from the door pocket 88 is in close contact with each shelf 60. Spaces separated by each form an independent space.

따라서, 해당 칸(55)에서만 냉기의 순환이 이루어지는 바, 이때 각 칸(55)의 후측 내상(66)에 부착된 온도센서(R1)(R2)(R3)에서 감지된 온도에 따라 냉장실 도어(80)에 설치된 흡입팬(92a)(92b)(92c)이 제어부의 제어신호에 따라 동작된다.Therefore, the cold air is circulated only in the compartment 55, in which case the refrigerator door according to the temperature detected by the temperature sensors R1, R2, and R3 attached to the rear inner case 66 of each compartment 55. Suction fans 92a, 92b and 92c provided in 80 are operated in accordance with the control signal of the controller.

그런데, 이러한 온도센서(R1)(R2)(R3)는 흡입팬(92a)(92b)(92c)과 각각 대응되게 제어되도록 제어부에 병렬연결되어 있어 R1에 의해 판단된 온도에 따라 1번 흡입팬(92a)의 회동 및 정지가 결정되고, R2는 2번 흡입팬(92b)을, R3는 3번 흡입팬(92c)의 회동 및 정지를 제어하게 되어 있다.However, the temperature sensors R1, R2, and R3 are connected in parallel to the control unit so as to be controlled to correspond to the suction fans 92a, 92b, and 92c, respectively, so that the suction fan is numbered once according to the temperature determined by R1. Rotation and stop of 92a are determined, R2 controls rotation and stop of the second suction fan 92b, and R3 controls rotation and stop of the third suction fan 92c.

또한, 이러한 흡입팬(92a)(92b)(92c)의 회동 및 정지의 판단 기준은, 예컨데 각 칸(55)의 내상(66)에 부착된 온도센서(R1)(R2)(R3)의 감지온도가 3℃이상이면 제어부는 해당 팬을 회동시키고 3℃이하이면 정지시키도록 개별 제어하며 상술한 제어는 냉장고의 운전중 제상모드를 제외하고 어느 모드에서든지 동작하도록 되어 있다.Incidentally, the criterion for determining the rotation and stop of the suction fans 92a, 92b and 92c is, for example, the detection of the temperature sensors R1, R2 and R3 attached to the inner box 66 of the respective compartments 55. If the temperature is 3 ° C or more, the control unit individually controls the fan to turn off and stops if the temperature is below 3 ° C. The above-described control operates in any mode except for the defrost mode during operation of the refrigerator.

따라서, 식품이 투입된 칸의 온도가 상승되면 센서에 의해 감지된 온도에 따라 흡입팬이 구동되어 해당 칸의 온도 상승된 냉기가 냉기덕트(90)로 흡입되어 사절부(50)에 형성된 리턴덕트(52b)를 냉각기실(10)로 귀환되므로, 자동적으로 냉각기실(10)의 냉기는 메인덕트(42)를 따라 멀티덕트(46)로 유입된 상태에서 해당 칸으로 공급되는 순환을 반복하게 된다.Therefore, when the temperature of the compartment into which the food is put is increased, the suction fan is driven according to the temperature sensed by the sensor so that the cold air having the elevated temperature of the compartment is sucked into the cold air duct 90 and the return duct formed in the trimming section 50. Since 52b) is returned to the cooler chamber 10, the cool air of the cooler chamber 10 is automatically repeated in a state in which the cool air of the cooler chamber 10 is introduced into the multi duct 46 along the main duct 42.

만약, 냉장실 도어(80)가 오픈된 후에 폐쇄되면 각 흡입팬이 동시 구동되어 냉장실의 모든 칸으로 냉기 공급이 이루어지므로 결국에는 고내 전체로 냉기공급이 일어나는 것과 동일하게 된다.If the refrigerating compartment door 80 is closed after being opened, each suction fan is simultaneously driven to supply cold air to all the compartments of the refrigerating compartment, and eventually, the cold air is supplied to the whole interior of the refrigerator.

이상에서 살펴 본 바와 같이, 본 발명에 따른 냉장고의 냉장실 선반 개별 냉각장치는, 냉장실 도어의 개폐에 따라 신속하게 정온화를 이룰 수 있으므로 보관식품의 빙결을 방지하고, 냉장실 전체에 비해 각 칸은 상대적으로 좁은 공간이므로 냉각속도도 향상되는 특장점을 제공하는 것이다.As described above, the refrigerator compartment shelf individual cooling apparatus of the refrigerator according to the present invention can quickly cool to the opening and closing of the refrigerator compartment door to prevent freezing of the stored food, each compartment relative to the entire refrigerator compartment As it is a narrow space, the cooling speed is also improved.
