본 발명은 입체 냉각방식 냉장고에 관한 것으로서, 더욱 상세하게는 냉장실 로 유입되는 냉기량을 조절하여 약냉을 방지하고, 냉장실의 좌우 온도편차 발생 시 그에 따라 온도제어를 수행하는 냉장고 및 그 제어방법에 관한 것이다. The present invention relates to a three-dimensional cooling type refrigerator, and more particularly, to a refrigerator and a method of controlling the same, by controlling the amount of cold air flowing into the refrigerating chamber to prevent weak cooling and performing temperature control according to the left and right temperature deviations of the refrigerating chamber. will be.

일반적으로, 냉장고는 음식물 등을 냉동시키거나, 냉장보관하기 위해 사용되는 것으로서, 그 내부에 냉동실과 냉장실로 분리된 수납공간을 형성하는 케이스 및 상기 케이스의 일측에 장착되어 냉동실과 냉장실을 개폐하는 냉동실 및 냉장실 도어와, 압축기, 응축기 및 증발기 등과 같이 냉동사이클을 이루어 냉동실과 냉장실의 온도를 낮추기 위한 기기들을 포함하여 구성되어 있다.In general, a refrigerator is used for freezing food or storing food in a refrigerator, and a case forming a storage space separated into a freezer compartment and a refrigerating compartment, and a freezer compartment installed at one side of the case to open and close a freezer compartment and a refrigerating compartment. And a refrigerator compartment door, and a device for lowering the temperature of the freezer compartment and the refrigerator compartment by forming a refrigeration cycle such as a compressor, a condenser, and an evaporator.

그리고, 이와 같은 냉장고의 냉각방식은 케이스 내에 구성된 냉기유로의 형태에 따라 단일 냉각방식과 입체 냉각방식으로 구분되는데, 단일 냉각방식은 냉기덕트가 케이스의 후면에만 구성됨으로써 냉기가 일측에서 집중 토출되는 방식이며, 입체 냉각방식은 냉기덕트가 케이스의 삼면에 고루 배치될 뿐만 아니라, 냉장실 도어에도 배치되어 냉기유로가 입체적으로 냉장실의 냉각공간을 둘러쌈으로써 냉기의 토출이 여러 방향에서 이루어지는 방식이다. In addition, the cooling method of such a refrigerator is divided into a single cooling method and a three-dimensional cooling method according to the shape of the cold air flow path configured in the case. In the single cooling method, the cold air duct is formed only at the rear of the case, where the cold air is concentrated at one side. In the three-dimensional cooling method, the cold air duct is not only evenly disposed on three sides of the case, but is also disposed in the refrigerating chamber door so that the cold air flow passage surrounds the cooling space of the refrigerating compartment three-dimensionally, thereby discharging the cold air in various directions.

상기 입체 냉각방식에 의하면 냉기의 토출이 여러 방향에서 이루어짐으로써 냉각공간내의 온도가 고르게 유지되기 때문에 단일 냉각방식에 비해 고내에 저장된 식품이 비교적 고르게 냉각된다. According to the three-dimensional cooling method, since the temperature of the cooling space is maintained evenly by discharging the cold air in various directions, the food stored in the refrigerator is relatively evenly cooled compared to the single cooling method.

그러나, 종래 입체 냉각방식은 도 1에 도시된 바와 같이 냉동실 팬(110) 구동에 의해 냉기가 격벽에 설치된 구멍(120)을 통하여 냉동실(100)로 유입됨과 동시에 냉장실 팬(210) 구동에 따라 냉기덕트(220)를 통해 냉장실(200)로 유입되는 구조를 가지고 있기 때문에 하나의 냉장실 팬만으로 냉장실을 냉각함으로써 유입되는 냉기의 양이 적어 약냉을 유발시킬 수 있고, 냉장실에 많은 부하가 들어 있는 경우 냉장실의 좌우 온도편차가 발생하는 문제점이 있었다. However, in the conventional three-dimensional cooling method, as shown in FIG. 1, the cold air is introduced into the freezer compartment 100 through the hole 120 installed in the partition wall by driving the freezer compartment fan 110, and at the same time, the cold air is driven in accordance with the operation of the refrigerator compartment fan 210. Since the structure is introduced into the refrigerating chamber 200 through the duct 220, the amount of cold air introduced by cooling the refrigerating chamber with only one refrigerating chamber fan is small, which may cause weak cooling, and when the refrigerating chamber has a large load, the refrigerating chamber There was a problem in which left and right temperature deviations occurred.

따라서, 본 발명은 상기와 같은 종래의 문제점을 해결하기 위해 창안한 것으로서, 복수개의 냉장실 팬을 구비하여 냉장실로 유입되는 냉기량을 조절하여 약냉을 방지하고, 냉장실의 좌우 온도편차 발생 시 그에 따라 온도제어를 수행하는 냉장고 및 그 제어방법을 제공하는데 그 목적이 있다. Accordingly, the present invention has been made to solve the above-mentioned conventional problems, it is provided with a plurality of refrigerator compartment fans to control the amount of cold air flowing into the refrigerator compartment to prevent weak cooling, when the left and right temperature deviation of the refrigerator compartment accordingly temperature It is an object of the present invention to provide a refrigerator for performing the control and a control method thereof.

이하, 본 발명의 실시예에 따른 구성을 첨부한 도면을 참조하여 상세히 설명하면 다음과 같다. Hereinafter, the configuration according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명의 실시예에 따른 입체 냉각방식 냉장고의 구성을 간략하게 보인 예시도이다. 2 is an exemplary view briefly showing a configuration of a three-dimensional cooling type refrigerator according to an embodiment of the present invention.

도 2에 도시한 바와 같이 냉동사이클을 통해 생성된 냉기는 냉동실 팬(110)의 구동을 통해 전방으로 토출하고, 냉동실 팬(110) 전면에는 냉동실 팬(110)과 냉동실(100)을 구획하는 격벽에 구멍(미도시)이 형성되어 있어 이를 통해 냉기가 냉동실(100)로 유입된다. As shown in FIG. 2, the cold air generated through the freezing cycle is discharged forward through the operation of the freezing compartment fan 110, and a partition wall partitioning the freezing compartment fan 110 and the freezing compartment 100 on the front side of the freezing compartment fan 110. Holes (not shown) are formed in the through which cold air flows into the freezing compartment (100).

그리고 상기 냉동실 팬(110)의 구동에 의해 토출되는 냉기는 냉기덕트(220)를 통해 냉장실(200) 방향으로 유도되는데, 냉기덕트(220) 내부의 좌, 우측에 위치하여 냉기를 냉장실로 유입되도록 하는 좌,우측 냉장실 팬(300, 310)이 있다. The cold air discharged by the driving of the freezer compartment fan 110 is guided to the refrigerating chamber 200 through the cold air duct 220, and is located at the left and right sides of the cold air duct 220 so that the cold air is introduced into the refrigerating chamber. There are left and right refrigerator compartment fans 300 and 310.

또한, 상기 냉기덕트(220) 초입에는 플랩(flap, 330)이 형성되어 있으며, 상기 플랩(330)은 냉동실 팬(110)만 구동 시에는 냉장실의 냉기가 역류하지 못하도록 냉기덕트(220) 입구를 막게 되고, 좌,우측 냉장실 팬(300, 310) 구동시에는 냉기가 냉기덕트(220)로 유입되도록 하는 역할을 하는데, 냉동실 팬(110) 또는 냉장실 팬(300, 310) 구동 시 냉기덕트(220) 입구를 온/오프할 수 있도록 비닐과 같은 가볍고 얇은 재질로 이루어져 있다. In addition, a flap 330 is formed at the beginning of the cold air duct 220, and the flap 330 opens an inlet of the cold air duct 220 so that cold air of the refrigerating compartment does not flow back when only the freezer compartment fan 110 is driven. When the left and right refrigerating chamber fans 300 and 310 are driven, the cold air is introduced into the cold air duct 220. The cold air duct 220 when the freezing chamber fan 110 or the refrigerating chamber fans 300 and 310 is driven. ) It is made of light and thin material such as vinyl to turn on / off the entrance.

또한, 상기 냉장실 좌,우측에는 냉장실의 온도를 감지하는 복수개의 온도감지센서(320, 321)가 위치한다. In addition, the left and right sides of the refrigerating compartment, a plurality of temperature detection sensors 320, 321 for detecting the temperature of the refrigerating compartment is located.

이와 같이 구성한 본 발명의 실시예에 따른 동작 과정을 첨부한 도면을 참조하여 설명하면 다음과 같다. Referring to the accompanying drawings, the operation process according to the embodiment of the present invention configured as described above is as follows.

도 3은 본 발명의 실시예에 따른 냉장실 좌우 온도편차 발생 시 제어 과정을 보인 흐름도이다. 3 is a flowchart illustrating a control process when a left and right temperature deviation occurs in the refrigerating chamber according to an exemplary embodiment of the present invention.

먼저, 상기 냉동실(100)을 제어수단(미도시)에서 일반제어 시에는 냉동사이클을 통해 생성된 냉기를 냉동실 팬(110)과 좌,우측 냉장실 팬(300, 310)을 구동하여 냉동실(100)과 냉장실(200)로 각각 냉기가 유입되도록 한다. First, when the freezer compartment 100 is controlled by a control means (not shown), the freezer generated by the freezing cycle is driven by the freezer compartment 110 and the left and right side refrigerator compartment fans 300 and 310 to freeze the compartment 100. And cold air flows into the refrigerating chamber 200, respectively.

이때 도 2에 도시한 바와 같이 플랩(330)은 좌,우측 냉장실 팬(300, 310)의 구동에 의해 열린 상태를 유지한다. In this case, as shown in FIG. 2, the flap 330 maintains an open state by driving the left and right refrigerating chamber fans 300 and 310.

한편, 도 3에 도시한 바와 같이 일반제어 시 상기 냉동실 팬(110)과 좌,우측 냉장실 팬(300, 310)의 구동을 정지한 후, 냉동실(100)을 냉각하고자 냉동실 팬(110)을 구동시키는 경우 상기 좌,우측 냉장실 팬(300, 310)의 구동은 정지한 상태로 있기 때문에 플랩(330)은 냉기덕트(220) 입구를 막게 되고, 이로 인하여 냉장실(200)의 냉기가 냉동실(100) 쪽으로 역류되는 현상을 방지하게 된다. Meanwhile, as shown in FIG. 3, after stopping the driving of the freezing compartment fan 110 and the left and right refrigerating compartment fans 300 and 310 during general control, the freezing compartment fan 110 is driven to cool the freezing compartment 100. In this case, since the driving of the left and right refrigerating compartment fans 300 and 310 is in a stopped state, the flap 330 blocks the inlet of the cold air duct 220, whereby cold air of the refrigerating compartment 200 is stored in the freezing compartment 100. This prevents backflow to the side.

이후, 냉장실(200)의 좌우측에 위치한 온도감지센서(320, 321)로부터 입력되 는 냉장실(200)의 좌우온도가 설정한 설정치(예를 들어 2℃)를 초과하는 경우가 발생하면(Step 300), 제어수단(미도시)은 좌측온도(T1)가 우측온도(T2)보다 높은가를 판단한다(Step 310). Subsequently, when the left and right temperatures of the refrigerating chamber 200 input from the temperature sensors 320 and 321 located on the left and right sides of the refrigerating chamber 200 exceed a set value (for example, 2 ° C.) set (Step 300). The control means (not shown) determines whether the left temperature T1 is higher than the right temperature T2 (Step 310).

상기 단계(Step 310)의 판단결과 좌측온도(T1)가 높은 경우에 좌측 냉장실 팬(300)을 구동하게 되고, 우측 냉장실 팬(310)은 구동을 오프하여 좌측으로만 냉기가 유입되도록 한다. 이때 냉동실 팬(110)의 구동은 오프한 상태로, 상기 플랩(330)은 냉기덕트(220) 입구를 오픈한 상태를 유지한다(Step 320). As a result of the determination of Step 310, when the left temperature T1 is high, the left refrigerating compartment fan 300 is driven, and the right refrigerating compartment fan 310 turns off the driving so that cold air flows only to the left side. At this time, the driving of the freezer compartment fan 110 is turned off, and the flap 330 maintains the opening of the cold air duct 220 inlet (Step 320).

만약, 상기 단계(Step 310)의 판단결과 우측온도(T2)가 높은 경우에는 반대로 우측 냉장실 팬(310)을 구동하고, 좌측 냉장실 팬(300)은 구동을 오프하여 우측으로만 냉기가 유입되도록 한다. 이때 냉동실 팬(110)의 구동은 오프한 상태로, 상기 플랩(330)은 냉기덕트(220) 입구를 오픈한 상태를 유지한다(Step 330). If the right temperature T2 is high as a result of the determination in step 310, the right refrigerating compartment fan 310 is reversely driven, and the left refrigerating compartment fan 300 turns off the driving so that the cold air flows only to the right side. . At this time, the driving of the freezer compartment fan 110 is turned off, and the flap 330 maintains the opening of the cold air duct 220 inlet (Step 330).

그러나 상기 단계(Step 300)에서 설정치를 초과하지 않는 경우에는 일반제어를 유지하도록 한다(Step 340).However, if the set value is not exceeded in the step 300, the general control is maintained (step 340).
