그러나 이와 같은 종래의 기술에 있어서, 냉장실이 정해진 온도에 도달하게 되면 댐퍼의 플랩(FLAP)이 닫힘으로 인해 냉기의 유로가 차단되어 냉기이 정체 및 그로 인한 냉장고 내부의 부하 증가로 냉장고내 우체 정체소음이 증가하게 되는 문제점이 있었다.However, in the conventional technology, when the refrigerator compartment reaches a predetermined temperature, the flow path of the cold air is blocked due to the flap of the damper being closed, and congestion of the postal noise in the refrigerator is caused by the cold air congestion and the increase in the load inside the refrigerator. There was a problem to increase.

따라서, 본 발명의 목적은 냉장실의 온도가 정해진 온도에 도달하면 댐퍼의 플랩이 닫혀 냉기의 흐름을 차단함으로써 발생하는 냉기유동 정체소음을 방지하기 위한 냉장고의 냉기순환량 제어장치를 제공하기 위한 것이다.Accordingly, an object of the present invention is to provide a cold air circulation control device for preventing a cold air flow stagnation noise caused by closing the flow of cold air by closing the flap of the damper when the temperature of the refrigerator compartment reaches a predetermined temperature.

본 발명의 다른 목적은 냉장고의 온도감지센서에 의해 댐퍼의 플랩이 닫히는 순간 팬모터 전압조절장치에 의해 팬의 RPM이 가변 되도록 하여 냉기순환량을 조절할 수 있도록 한 냉장고의 냉기순환량 제어장치를 제공하기 위한 것이다.Another object of the present invention is to provide a cold air circulation control device for controlling the cold air circulation by changing the RPM of the fan by the fan motor voltage regulator at the moment the flap of the damper is closed by the temperature sensor of the refrigerator. will be.

본 발명의 다른 목적은 냉동실 온도감지센서의 작동에 의해 콤프레샤가 온/오프하고, 그 콤프레샤가 온 되었을 때 팬모터의 RPM이 가변되도록하여 냉기순환량을 조절하도록 하는 냉장고의 냉기순환량 제어장치를 제공하기 위한 것이다.It is another object of the present invention to provide a cold air circulation control device for controlling a cold air flow rate by adjusting the temperature of the compressor when the compressor is turned on / off by the operation of the freezer compartment temperature sensor and the RPM of the fan motor is variable. It is for.

상기 목적을 달성하기 위한 본 발명 냉장고의 냉기순환량 제어장치 구성은 제2도에 도시된 바와 같이 파워코드(1)를 통해 파워인가시 온/오프하여 냉장실 고내(10)의 온도를 조절하는 콤프레샤(2)와, 냉동실의 온도를 감지하는 냉동실 온도감지센서(3)와, 상기 콤프레샤(2)의 온/오프동작에 따라 냉장실 고내(10)의 온도가 변하면 이를 감지하는 냉장실 온도감지센서(5)와, 상기 냉동실 온도감지센서(3)에 의해 감지된 온도에 따라 온 또는 오프하여 상기 콤프레샤(2)와 팬모터(6')를 동작 또는 차단하는 제1스위치(4)와, 상기 냉장실 온도감지센서(3)에 의해 감지된 냉장실의 온도에 따라 플랩(FLAP)을 열거나 닫도록 하여 냉장실의 온도를 조절하는 댐퍼(9)와, 팬(6)을 구동하여 냉기를 냉장실과 냉동실로 발생시키도록 구동시키는 팬모터(6')와, 상기 댐퍼(9)의 플립 개폐여부에 따라 스위칭하여 상기 팬모터(6')로 정상전압 또는 가변된 전압을 전달하여 주기위한 제2스위치(7)와, 상기 제2스위치(2)와 접속시 상기 팬모터(6')로 공급되는 전압의 가변시켜 팬의 풍량을 조절하는 팬모터 전압조절기(8)로 구성한다.In order to achieve the above object, the refrigerator air flow control device of the present invention has a compressor for controlling the temperature of the refrigerator compartment 10 by turning on / off when power is applied through the power cord 1 as shown in FIG. 2), a freezer compartment temperature sensor 3 for detecting a temperature of the freezer compartment, and a refrigerator compartment temperature sensor 5 for detecting a change in the temperature of the refrigerator compartment 10 according to the on / off operation of the compressor 2.

The damper 9 adjusts the temperature of the refrigerator compartment by opening or closing the flap FLAP according to the temperature of the refrigerator compartment sensed by the sensor 3, and the fan 6 is driven to generate cold air into the refrigerator compartment and the freezer compartment. The fan motor 6 'and the damper 9 are flipped A second switch 7 for transmitting a normal voltage or a variable voltage to the fan motor 6 'by switching according to whether it is closed, and the fan motor 6' when connected to the second switch 2; It consists of a fan motor voltage regulator (8) for controlling the air volume of the fan by varying the voltage supplied to.

이와 같이 구성된 본 발명의 작용 및 효과에 대하여 상세히 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured as described above in detail.

냉장실 고내(10)의 온도를 감지하는 냉장실 온도감지센서(5)에 감지된 온도가 정해진 온도(약 3℃)에 도달하면 냉장실 댐퍼(9)의 플랩이 닫히게 된다. 이때 중앙연산장치(14)는 냉장실 댐퍼(9)로부터 닫힘신호를 입력받아 기억하여 둔다. 상기 댐퍼(9)의 플랩이 닫히더라도 콤프레샤(2) 및 팬(6'), 팬모터(6)는 파워코드(1)를 통해 들어오는 입력전압(220V)에 의해 운전하고, 회전하여 팬(6)에 의해 풍량이 나오게 된다.The flap of the refrigerator compartment damper 9 is closed when the temperature detected by the refrigerator compartment temperature sensor 5 sensing the temperature of the refrigerator compartment 10 reaches a predetermined temperature (about 3 ° C.). At this time, the central computing device 14 receives the closing signal from the refrigerating chamber damper 9 and stores it. Even when the flap of the damper 9 is closed, the compressor 2, the fan 6 ′, and the fan motor 6 are driven by the input voltage 220V supplied through the power cord 1, and rotated so that the fan 6 is rotated. ), The air volume comes out.

이로 인해 냉장실 고내(10)로 냉기가 공급되어야 하는데 상기 댐퍼(9)에 의해 차단되어 있으므로 바람이 유로내에 정체되어 쌓이므로 소음의 증가원인이 된다. 따라서 냉장실 댐퍼(9)의 플랩이 닫히는 순간 제2스위치(7)의 가동단자가 제1스위치(4)의 출력과 연결되던 것을 팬모터 전압조절기(8) 쪽으로 스위칭한다. 그러면 상기 팬모터(6')에 공급되는 전압을 가변시켜 팬(6)의 RPM을 저하시킴으로 팬풍량을 작게하여 정체압을 줄여 소음을 저감시킨다.Because of this, cold air must be supplied to the refrigerating compartment 10, and since the wind is blocked by the damper 9, the wind is stagnated and accumulated in the flow path, thereby causing an increase in noise. Therefore, the moment that the flap of the refrigerating chamber damper 9 is closed, the movable terminal of the second switch 7 is connected to the output of the first switch 4 toward the fan motor voltage regulator 8. Then, by varying the voltage supplied to the fan motor (6 ') to lower the RPM of the fan (6) by reducing the fan air volume to reduce the stagnation pressure to reduce the noise.

즉, 중앙연산장치(14)는 팬모터속도감지부(12)가 팬모터(6')의 속도를 감지함에 따라 속도설정부(13)에서 팬모터속도에 따라 설정된 RPM을 입력 받으면, 그 설정된 RPM값에 따른 RPM값을 선정하여 팬모터조정부(15)로 전달하면 상기 팬모터 조정부(15)에서 조정된 RPM으로 팬모터를 구동한다.That is, the central computing unit 14 receives the RPM set according to the fan motor speed from the speed setting unit 13 as the fan motor speed detecting unit 12 detects the speed of the fan motor 6 ', and sets the RPM. When the RPM value according to the value is selected and transmitted to the fan motor adjusting unit 15, the fan motor is driven at the RPM adjusted by the fan motor adjusting unit 15.

그리고 냉동실 공간(11)의 온도를 냉동실 감지온도센서(3)가 감지했을 때 그 감지된 온도가 정해진 온도(약 -18℃)에 도달하면 제1스위치(4)가 오프되어 콤프레샤(2)와 팬모터(6')의 운전을 정지시킨다.When the temperature of the freezer compartment 11 is detected by the freezer compartment sensing temperature sensor 3, when the sensed temperature reaches a predetermined temperature (about −18 ° C.), the first switch 4 is turned off to provide the compressor 2 with the compressor 2. The operation of the fan motor 6 'is stopped.

또한, 냉동실 및 냉장실의 온도가 정해진 온도 이상으로 올라가면 상기 냉동실 감지온도센서(3)의 감지에 의해 제1스위치(4)를 온되어 상기 콤프레샤(2)와 팬모터(6')가 운전되도록 하고 냉장실 감지온도센서(5)의 감지에 의해 제2스위치(7)의 접지방향이 결정되어 운전을 계속한다.In addition, when the temperature of the freezer compartment and the refrigerating compartment rises above a predetermined temperature, the first switch 4 is turned on by the detection of the freezer compartment sensing temperature sensor 3 so that the compressor 2 and the fan motor 6 'are operated. The ground direction of the second switch 7 is determined by the detection of the refrigerating compartment sensing temperature sensor 5 to continue operation.

이상에서 상세히 설명한 바와 같이 본 발명은 냉장실의 온도값을 읽어들여 설정온도와 비교하여 냉장실 온도가 설정온도보다 낮다고 판단되면 댐퍼(9)를 닫고, 팬모터(6')의 속도를 감지하고 그 감지신호에 따라 적정 팬모터 회전수를 설정한다. 그런다음 그 설정된 값에 따라 상기 팬모터(6')의 RPM수를 가변시켜 풍량을 줄여줌으로써 정체에 의한 유체 유동소음을 줄이고, 또한 팬모터의 입력전력을 줄임으로써 소비전력 저감의 효과가 있도록 한 효과가 있다.As described in detail above, the present invention reads the temperature value of the refrigerating compartment and compares it with the set temperature, if it is determined that the refrigerating compartment temperature is lower than the set temperature, closes the damper 9, detects the speed of the fan motor 6 ', and detects the same. Set the proper fan motor speed in accordance with the signal. Then, by varying the number of RPM of the fan motor (6 ') according to the set value to reduce the air flow to reduce the fluid flow noise due to stagnation, and also to reduce the power consumption of the fan motor to reduce the power consumption. It works.
