도 1은 종래 냉장고의 냉기 토출구조의 일예를 보인 사시도로서, 도시된 바와 같이, 종래에는 냉장고의 케이스 내측에 수개의 선반(1)이 설치되어 있고, 그 선반(1)의 내측에는 가장자리를 따라 냉기유로(2)가 형성되어 있으며, 그 냉기유로(2)상의 하방으로는 다수개의 분사공(2a)이 형성되어 있다.1 is a perspective view showing an example of a cold air discharge structure of a conventional refrigerator, as shown in the related art, several shelves 1 are conventionally installed inside a case of a refrigerator, and inside the shelf 1 along an edge thereof. The cold air flow passage 2 is formed, and a plurality of injection holes 2a are formed below the cold air flow passage 2.
이와 같은 냉기 토출구조에서는 냉기유로(2)를 따라 유입된 냉기가 냉기유로(2)상에 형성되어 있는 다수개의 분사공(2a)을 통하여 동시에 분사되어 냉장고의 내측에 위치한 부하를 냉각시킨다.In such a cold air discharge structure, cold air introduced along the cold air flow path 2 is simultaneously sprayed through a plurality of injection holes 2a formed on the cold air flow path 2 to cool the load located inside the refrigerator.
도 2는 종래 냉장고의 냉기 토출구조의 다른 예를 보인 사시도로서, 도시된 바와 같이 종래에는 냉장실(3)의 후면벽에 칸칸마다 수개의 토출공(3a)을 형성하고, 그 토출공(3a)을 통하여 냉장실(3)의 내측에 냉기를 공급하게 된다.FIG. 2 is a perspective view showing another example of a cold air discharge structure of a conventional refrigerator. As shown in the related art, several discharge holes 3a are formed in each rear space of a rear wall of the refrigerating chamber 3, and the discharge holes 3a are formed. Through the supply of cold air to the inside of the refrigerating chamber (3).
그러나, 도 1과 같은 종래의 냉기 토출구조에서는 새로운 부하를 냉장고의 내측에 수납하면 선반(1)의 냉기유로(2) 상에 형성된 다수개의 분사공(2a)을 통하여 동시에 냉기가 분사되기 때문에 이미 냉각된 부하에도 냉기가 공급되어 새로운 부하를 냉각시키는데는 많은 시간이 소요되는 문제점이 있었다. 도 2와 같은 종래의 냉기 토출구조에는 냉기 유입부에 방향조절장치를 부착하면 부하의 위치에 따라 냉기를 조절할 수 있으나, 토출공(3a)의 전방에 냉각된 부하가 위치하면 토출공(3a)에서 멀리 떨어져 있는 새로운 부하에는 소량의 냉기가 공급되어 냉각시간이 길어지게 되는 문제점이 있었다.However, in the conventional cold air discharging structure as shown in FIG. 1, when the new load is stored inside the refrigerator, cold air is simultaneously injected through the plurality of injection holes 2a formed on the cold air flow path 2 of the shelf 1.

On the upper surface of the lower plate 11 for injecting cold air into the hole 11a, a flow plate 12 having a smaller size than the lower plate 11 and divided into four parts and having a through hole 12a is provided, and the flow plate Positioning means 13 for moving the flow plate 12 in accordance with the position of the load is provided on the upper portion of the 12, the cold air between the flow plate 12 and the upper portion of the position adjusting means 13 Forming the space portion 14 is introduced, the position adjusting means 13 is fixed, and the upper plate 15 on which the storage items are placed on the upper surface is installed, the left and right of the front and rear of the lower plate 11, Four temperature sensors 16, such as an infrared sensor, for detecting the temperature of the load are respectively installed in the right four parts S1, S2, S3, and S4.
상기 위치조절수단(13)은 상기 상판(15)의 하면에 고정되는 스텝 모터(20)와, 그 모터(20)의 모터축(20a)에 결합됨과 아울러 유동판(12)의 중앙에 형성된 결합공(12b)에 삽입되어 유동판(12)을 이동시키기 위한 캠(21)으로 구성된다.The position adjusting means 13 is coupled to the step motor 20 fixed to the lower surface of the upper plate 15 and the motor shaft 20a of the motor 20 and formed at the center of the flow plate 12. It is composed of a cam 21 inserted into the ball 12b to move the flow plate 12.

상기와 같이 구성되어 있는 본 발명 냉장고의 냉기 분배장치의 동작을 설명하면 다음과 같다.Referring to the operation of the cold air distribution apparatus of the present invention refrigerator configured as described above are as follows.
하판(11)의 전, 후부의 좌, 우측(S1)(S2)(S3)(S4)에 각각 설치되어 있는 온도감지센서(16)중 S3의 위치에 설치되어 있는 온도감지센서(16)가 하부에 온도가 높은 부하가 수납된 것이 감지되면 위치조절수단(13)의 스텝 모터(20)가 회전을 하고, 그 스텝 모터(20)의 모터축(20a)에 설치된 캠(21)이 회전을 하여, 캠(21)이 결합되어 있는 유동판(12)을 도 5a와 같이 S3의 위치로 이동한다. 이와 같이 유동판(12)이 S3의 위치로 이동하면 유동판(12)에 형성된 관통공(12a)들과 하판(11)의 S3 위치에 형성된 분사공(11a)들을 일치시켜서 냉기를 온기가 있는 부하에 집중적으로 분사하고 나머지 S1, S2, S4의 위치에 있는 분사공(11a)들은 밀폐하여 냉기의 분사를 차단한다.Among the temperature sensors 16 installed at the left and right sides S1, S2, S3, and S4 of the front and rear portions of the lower plate 11, the temperature sensor 16 is provided at the position of S3. When it is detected that a load having a high temperature is stored in the lower portion, the step motor 20 of the position adjusting means 13 rotates, and the cam 21 installed on the motor shaft 20a of the step motor 20 rotates. Thus, the flow plate 12 to which the cam 21 is coupled is moved to the position of S3 as shown in FIG. 5A. When the flow plate 12 moves to the position S3 as described above, the through holes 12a formed in the flow plate 12 coincide with the injection holes 11a formed at the position S3 of the lower plate 11, where the cold air is warmed. Injecting intensively to the load and the injection holes (11a) in the positions of the remaining S1, S2, S4 is sealed to block the injection of cold air.
상기와 같이 하판(11)의 4부분에 집중적으로 형성되어 있는 어느 한곳의 분사공(11a)들과 유동판(12)에 형성된 관통공(12a)들을 일치시키는 방법으로 부하의 위치에 따라 나머지 S1, S2, S4부분으로도 냉기를 집중적으로 분사할 수 있다.As described above, the one or more injection holes 11a formed in four parts of the lower plate 11 and the through holes 12a formed in the flow plate 12 are matched to each other according to the position of the load. , S2, S4 part can intensively spray cold air.
도 6은 본 발명의 제어동작을 설명하기 위한 플로우차트로서, 도시된 바와 같이, 냉장고의 적정온도가 될때의 센서값을 K로 설정시켜 놓은 상태에서 먼저 각 위치의 센서값을 읽는다. 그런 다음, 우선 Y를 최적의 K값으로 치환한다. 그런 다음, 각 온도감지센서(16)의 값을 최초 K값과 비교하여 값이 가장높은 센서값과 온도감지센서(16)의 위치를 비교판정한다. 그런 다음, 가장 높은 곳이 최적값보다 높은가를 판정한다. 그런 다음, Y가 K보다 높으면 냉각팬을 돌리면서 스텝 모터(20)를 구동시켜서 가장 높은 온도감지센서(16)가 설치된 위치에 냉기가 공급되도록 유동판(12)을 이동시킨다.6 is a flowchart for explaining the control operation of the present invention. As shown in the drawing, the sensor value at each position is first read in a state in which the sensor value at the proper temperature of the refrigerator is set to K. Then, Y is first replaced with an optimal K value. Then, the value of each temperature sensor 16 is compared with the initial K value to determine the position of the sensor value having the highest value and the temperature sensor 16. Then, it is determined whether the highest place is higher than the optimum value. Then, if Y is higher than K, driving the step motor 20 while rotating the cooling fan to move the flow plate 12 so that cold air is supplied to the position where the highest temperature sensor 16 is installed.
이상에서 상세히 설명한 바와 같이 본 발명 냉장고의 냉기 분배장치는 하판의 전, 후부의 좌, 우측에 각각 집중적으로 형성되어 있는 분사공들과, 유동판에 형성되어 있는 관통공들을 일치시켜서 온도감지센서에 의해 높은 온도가 감지된 부하에 집중적으로 냉기가 분사되도록 함으로서, 단시간에 부하를 냉각시키는 효과가 있다.As described in detail above, the cold air distribution apparatus of the present invention includes a plurality of injection holes formed centrally on the left and right sides of the lower plate, and through holes formed on the fluid plate to match the temperature sensor. By injecting cold air intensively to the load detected a high temperature, there is an effect of cooling the load in a short time.
