본 발명은 입체 냉각방식 냉장고에 관한 것으로서, 더욱 상세하게는 냉장실 집중냉각 또는 냉장실의 좌우 온도와 중앙부 온도의 편차에 따라 냉장실의 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 for controlling the temperature of the refrigerating chamber according to a deviation between the left and right temperatures and the central temperature of the refrigerating chamber.

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 동시 에 냉장실 팬(210) 구동에 따라 냉기덕트(220)를 통해 냉장실(200)로 유입되는 구조를 가지고 있기 때문에 냉장실 집중냉각 시에는 냉장실 팬만으로 냉각을 하여야 하기 때문에 약냉으로 인한 냉각효율이 떨어 되고, 냉장실에 많은 부하가 들어 있는 경우 냉동실의 좌우 온도와 중앙부 온도의 편차가 발생하는 문제점이 있었다. However, in the conventional three-dimensional cooling method, as shown in FIG. 1, as the cold air flows into the freezer compartment 100 through the holes 120 installed in the partition wall by driving the freezer compartment fan 110, the refrigerator compartment fan 210 is driven at the same time. Since the cold air duct 220 has a structure that flows into the refrigerating chamber 200, the cooling efficiency due to the weak cooling is reduced because only the refrigerating chamber fan needs to be cooled in the refrigerating chamber intensive cooling, and the refrigerating chamber has a large load in the refrigerating chamber. There was a problem that the difference between the left and right temperature and the central temperature.

따라서, 본 발명은 상기와 같은 종래의 문제점을 해결하기 위해 창안한 것으로서, 정회전과 역회전이 가능한 냉동실 팬과, 냉장실 중앙부에 위치하는 냉장실 팬을 구비하여 냉장실을 냉각할 수 있는 냉장고 및 그 제어방법을 제공하는데 그 목적이 있다. Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and includes a freezer compartment fan capable of forward and reverse rotation, and a refrigerator compartment fan located at the center of the refrigerating compartment and cooling the refrigerator. The purpose is to provide a method.

이와 같은 목적을 달성하기 위한 본 발명에 따른 입체 냉각방식 냉장고는, 입체 냉각방식 냉장고에 있어서, 정회전 및 역회전이 가능한 냉동실 팬, 상기 냉동실 팬의 구동에 의해 토출되는 냉기가 냉장실로 유도되도록 형성되어진 냉기덕트 내부에 위치하여 냉기를 냉장실의 중앙부로 유입되도록 하는 냉장실 팬을 포함하는 것을 특징으로 한다. The three-dimensional cooling type refrigerator according to the present invention for achieving the above object is, in the three-dimensional cooling type refrigerator, the freezer compartment capable of forward and reverse rotation, the cold air discharged by the drive of the freezer compartment fan is formed to guide the refrigerating chamber Located in the cold air duct is characterized in that it comprises a refrigerating compartment fan to allow the cold air flow into the central portion of the refrigerating compartment.

또한, 본 발명에 다른 입체 냉각방식 냉장고는 상기 냉장실 내 좌우측 및 중앙부에 위치하여 냉장실내 온도변화를 감지하는 복수개의 온도감지수단, 상기 냉동실 냉각을 위하여 냉동실 팬이 정회전 시에는 냉장실의 냉기가 역류하지 못하도록 하고, 냉장실 팬 구동시에는 냉기가 냉기덕트로 유입되도록 하는 플랩(flap) 및 상기 온도감지수단에서 감지한 온도변화에 따라 상기 냉동실 팬 및 냉장실 팬을 선택 제어하는 제어수단을 더 포함하는 것을 특징으로 한다. In addition, the three-dimensional cooling method refrigerator according to the present invention is located in the left and right sides and the center of the refrigerating chamber a plurality of temperature sensing means for detecting the temperature change in the refrigerating chamber, when the freezer compartment for the cooling of the freezer compartment forward rotation of the cold air in the refrigerating compartment And a flap for allowing cold air to flow into the cold air duct and a control means for selectively controlling the freezer compartment fan and the refrigerating compartment fan according to a temperature change detected by the temperature sensing means when the refrigerating fan is driven. It features.

또한, 본 발명에 따른 입체 냉각방식 냉장고는 상기 제어수단의 제어신호에 따라 상기 냉장실 팬으로 유도되는 냉기를 차단 또는 공급하는 댐퍼를 더 포함하는 것을 특징으로 한다. In addition, the three-dimensional cooling method refrigerator according to the invention is characterized in that it further comprises a damper for blocking or supplying the cold air guided to the refrigerator compartment fan in accordance with the control signal of the control means.

그리고, 본 발명에 다른 입체 냉각방식 냉장고 제어방법은, 냉동실 온도제어 시에는 냉동실 팬을 정회전시켜 냉동실로 냉기가 유도되도록 제어하는 단계 및 냉장실의 온도를 감지하여 설정온도를 초과하는 경우 냉장실 집중냉각으로 판단하여 상기 냉동실 팬을 역회전시킴과 동시에 댐퍼 및 냉장실 팬을 구동하여 냉장실 온도를 제어하는 단계를 포함하는 것을 특징으로 한다. In addition, the three-dimensional cooling method of the refrigerator control method according to the present invention, during the freezer compartment temperature control, the step of controlling the freezing chamber fan to forward the cold air into the freezer compartment and detecting the temperature of the refrigerating compartment when the temperature exceeds the set temperature in the refrigerator compartment intensive cooling And determining the temperature of the refrigerator compartment by rotating the freezer compartment fan at the same time and driving a damper and a refrigerator compartment fan.

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 정회전과 역회전이 가능한 냉동실 팬(300)의 구동을 통해 전방으로 토출하는데, 냉동실 팬(300)의 전면에는 냉동실 팬(300)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 300 capable of forward rotation and reverse rotation, and the freezing compartment fan 300 is provided on the front surface of the freezing compartment fan 300. Holes (not shown) are formed in the partition wall partitioning the freezer compartment 100 so that cold air flows into the freezer compartment 100.

그리고 상기 냉동실 팬(300)의 역회전에 의해 토출되는 냉기는 냉기덕트(220)를 통해 냉장실(200) 방향으로 유도되는데, 냉기덕트(220) 초입에는 플 랩(flap, 350)이 형성되어 있으며, 상기 플랩(350)은 냉동실 팬(300)의 정회전 시에 냉장실(200)의 냉기가 역류하지 못하도록 냉기덕트(220) 입구를 막게 되고, 냉장실 팬(310) 구동시에는 냉기가 냉기덕트(220)로 유입되도록 하는 역할을 하며, 냉기의 흐름에 따라 냉기덕트 입구를 온/오프할 수 있도록 비닐과 같은 가볍고 얇은 재질로 이루어져 있다. The cold air discharged by the reverse rotation of the freezer compartment fan 300 is guided to the refrigerating chamber 200 through the cold air duct 220, and a flap 350 is formed at the beginning of the cold air duct 220. The flap 350 blocks the inlet of the cold air duct 220 so that the cold air of the refrigerating compartment 200 does not flow backward when the freezing chamber fan 300 rotates forward, and the cold air duct is driven when the cold compartment fan 310 is driven. 220) and is made of a light and thin material such as vinyl to turn on / off the inlet of the cold air duct according to the flow of cold air.

또한, 상기 냉장실 팬(310)은 냉장실 중앙부에 위치한 냉기덕트 내부에 위치하는데, 냉기를 유도하는 중앙부 냉기덕트의 초입에는 댐퍼(340)가 위치하여 냉기를 차단 또는 공급하는 역할을 수행하며, 상기 냉장실 좌,우측 및 중앙부에는 냉장실의 온도를 감지하는 복수개의 온도감지센서(320, 321, 322)가 위치한다. In addition, the refrigerating compartment fan 310 is located in the cold air duct located in the center of the refrigerating compartment, the damper 340 is located at the beginning of the central cold air duct to induce cold air serves to block or supply the cold air, the cold compartment On the left, right side and the center portion, a plurality of temperature detection sensors 320, 321, and 322 for detecting the temperature of the refrigerating chamber are located.

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

도 3은 본 발명의 실시예에 따른 냉장실 집중냉각 시 제어 과정을 보인 흐름도이다. 3 is a flowchart illustrating a control process when the refrigerator compartment is concentrated in accordance with an embodiment of the present invention.

도 4는 본 발명의 실시예에 따른 냉장실 좌우 온도와 중앙부 온도의 편차 발생 시 제어 과정을 보인 흐름도이다. 4 is a flowchart illustrating a control process when a deviation between a left and right temperature and a central temperature occurs in the refrigerating chamber according to an exemplary embodiment of the present invention.

도 3에 도시한 바와 같이 먼저, 제어수단(미도시)에서 일반제어 즉 냉동실(100) 및 냉장실(200) 온도제어 시에는 냉동사이클을 통해 생성된 냉기를 냉동실 팬(300)과 댐퍼(340) 및 냉장실 팬(310)을 구동하여 냉동실(100)과 냉장실(200)로 각각 냉기가 유입되도록 한다. As shown in FIG. 3, first, during the general control, that is, the temperature control of the freezer compartment 100 and the refrigerating chamber 200 in the control means (not shown), the cold air generated through the freezing cycle is freezer compartment fan 300 and damper 340. And driving the refrigerating compartment fan 310 to allow cold air to flow into the freezing compartment 100 and the refrigerating compartment 200, respectively.

이때, 도 2에 도시한 바와 같이 플랩(350)은 냉장실 팬(310)의 구동에 의해 열린 상태를 유지한다. In this case, as shown in FIG. 2, the flap 350 maintains an open state by driving the refrigerating compartment fan 310.

이후, 냉동실(100) 및 냉장실(200)의 온도가 설정온도에 도달하면 상기 냉동실 팬(300)과 냉장실 팬(310)의 구동을 정지한 후, 냉동실 온도가 설정온도를 초과하여 냉동실(100)을 냉각하고자 냉동실 팬(300)을 정회전하는 경우, 상기 냉장실 팬(310) 및 댐퍼(340)의 구동은 정지한 상태로 있기 때문에 냉기의 흐름에 의해 플랩(350)은 냉기덕트(220) 입구를 막게 되고, 이로 인하여 냉장실(200)의 냉기가 냉동실(100) 쪽으로 역류되는 현상을 방지하게 된다. Thereafter, when the temperatures of the freezer compartment 100 and the refrigerating chamber 200 reach a set temperature, the driving of the freezer compartment fan 300 and the refrigerating compartment fan 310 is stopped, and the freezer compartment temperature exceeds the set temperature. When the freezer compartment fan 300 is rotated forward to cool, the refrigerating compartment fan 310 and the damper 340 are in a stopped state, and thus the flap 350 opens the inlet of the cold air duct 220 by the flow of cold air. This prevents the phenomenon that the cold air of the refrigerating compartment 200 flows back toward the freezing compartment 100.

한편, 도 3에 도시한 바와 같이 냉장실 온도가 집중냉각 돌입 온도에 도달하는 경우(Step 300), 제어수단은 냉동실 팬(300)을 역회전하도록 함과 동시에 댐퍼(340) 및 냉장실 팬(310)을 온 제어하여 냉기가 냉장실(200)로 유입되도록 한다(Step 310 ~ 320). 이때 상기 플랩(350)은 냉기의 흐름에 의해 열린 상태를 유지한다. On the other hand, when the refrigerator compartment temperature reaches the intensive cooling inrush temperature as shown in FIG. 3 (Step 300), the control means to rotate the freezer compartment 300 in reverse, the damper 340 and the refrigerator compartment fan 310 at the same time. On to control the cold air to be introduced into the refrigerating chamber 200 (Step 310 ~ 320). At this time, the flap 350 maintains an open state by the flow of cold air.

이후, 집중냉각 돌입 온도 이하로 온도가 낮아지면 집중냉각을 해제하고, 일반제어로 전환한다(Step 330 ~ Step 350).Thereafter, when the temperature drops below the intensive cooling inrush temperature, the concentrated cooling is released, and the control is switched to general control (Step 330 to Step 350).

또한, 도 4에 도시한 바와 같이 온도감지센서(320, 321, 322)로부터 감지한 냉장실(200)의 좌우측 온도와 중앙부 온도의 차가 설정치(예를 들어 2℃)를 초과하는 경우(Step 400), 좌우측 온도가 중앙부 온도보다 높은가를 판단한다(Step 410). In addition, as shown in FIG. 4, when the difference between the left and right and center temperature of the refrigerating chamber 200 detected by the temperature sensors 320, 321, and 322 exceeds the set value (for example, 2 ° C.) (Step 400). In step 410, it is determined whether the left and right temperatures are higher than the central temperature.

상기 단계(Step 410)의 판단결과 높은 경우 댐퍼(340)와 냉장실 팬(310)의 구동을 정지시키고, 냉동실 팬(300)을 역회전하도록 하여 냉기가 냉장실(200)의 좌우측으로만 공급되도록 한다(Step 420 ~ 430). When the determination result of step 410 is high, the driving of the damper 340 and the refrigerating compartment fan 310 is stopped, and the freezing compartment fan 300 is rotated in reverse so that cold air is supplied only to the left and right sides of the refrigerating compartment 200. (Step 420-430).

그러나, 상기 단계(Step 410)의 판단결과 중앙부의 온도가 더 높은 경우에는 댐퍼(340)와 냉장실 팬(310)을 온 제어하여 중앙부로 냉기가 공급되도록 하며(Step 440), 이때에도 상기 플랩(350)은 냉기의 흐름에 의해 열린 상태를 유지한다. However, when the temperature of the central portion is higher as a result of the determination in step 410, the damper 340 and the refrigerator compartment fan 310 are controlled on so that the cold air is supplied to the central portion (Step 440). 350 is maintained open by the flow of cold air.

만약, 상기 단계(Step 400)의 판단결과 설정치 이하인 경우에는 일반제어를 계속 유지한다(Step 450).If the determination result of the step (Step 400) is less than the set value, the general control is maintained (Step 450).

이상에서 설명한 바와 같이 본 발명에 따른 입체 냉각방식 냉장고 및 그 제냉장실 집중냉각 시에 냉동실 팬과 냉장실 팬으로 냉각을 하기 때문에 약냉으로 인한 냉각효율이 떨어지는 것을 방지하고, 냉장실에 많은 부하가 들어 있는 경우 냉장실의 좌우 온도와 중앙부 온도의 편차가 발생하여도 댐퍼와 냉장실 팬을 구동하여 이를 바로 대처할 수 있는 효과가 있다. As described above, when the three-dimensional cooling method according to the present invention and the intensive cooling of the refrigerating chamber are cooled by the freezing compartment fan and the refrigerating compartment fan, the cooling efficiency due to the weak cooling is prevented from falling, and the refrigerating compartment has a large load. Even if the temperature difference between the left and right and the central temperature of the refrigerating chamber is driven, there is an effect that can be coped immediately by driving the damper and the refrigerating chamber fan.
