일반적인 냉장고의 냉기 순환구조는 제1도에 도시되어 있는 바와 같이, 증발기(13)에서 발생한 냉기가 팬(14)에 의하여 냉동실(8)과 냉장실(9)로 순환되어 냉장고내의 온도를 유지할 수 있도록 하고 있으며, 이때 증발기(13)에서 발생하여 팬(14)에 의하여 토출된 냉기가 냉장실(9)내에 설치되어 있는 냉기 통풍로(16)를 따라 냉장실(9)내에서 화살표방향으로 순환되도록 되어 있다. 여기서, 팬(14)은 팬모터(24)의 구동에 의해 회전되며, 팬모터(24)는 팬모터구동부(35)에 의해 제어된다. 그리고, 온도센서(20)에서 감지된 냉장고내온도는 온도검출부(28)에서 처리된다. 또한, 상기와 같은 냉기 순환구조를 갖는 냉장고는 도어(6)의 열림/닫힘을 도어스위치(18)로부터 검출하는 도어개폐 검출부(25)와, 압축기(17)를 구동하는 압축기 구동부(37)와, 냉기의 흐름량을 조절하는 댐퍼(34)를 구동하는 댐퍼 구동부(34)와, 온도검출부(28)에 의해 검출된 냉장고내 온도로부터 팬모터(24), 압축기(17), 댐퍼(23)의 각 구동량을 연산하고 상기 각 구동수단을 제어하는 제어부(36)를 구비한다.As shown in FIG. 1, the cold air circulation structure of the general refrigerator is such that cold air generated in the evaporator 13 is circulated by the fan 14 to the freezer compartment 8 and the refrigerator compartment 9 to maintain the temperature in the refrigerator. At this time, the cool air generated by the evaporator 13 and discharged by the fan 14 is circulated in the direction of the arrow in the refrigerating chamber 9 along the cold air vent 16 installed in the refrigerating chamber 9. . Here, the fan 14 is rotated by the drive of the fan motor 24, the fan motor 24 is controlled by the fan motor driver 35. In addition, the temperature inside the refrigerator detected by the temperature sensor 20 is processed by the temperature detector 28. In addition, the refrigerator having the cold air circulation structure as described above includes a door opening and closing detection unit 25 for detecting the opening / closing of the door 6 from the door switch 18, a compressor driving unit 37 for driving the compressor 17, and The damper driver 34 for driving the damper 34 for adjusting the flow rate of cold air and the temperature of the refrigerator motor detected by the temperature detector 28 of the fan motor 24, the compressor 17, and the damper 23. And a control unit 36 for calculating each driving amount and controlling the respective driving means.
상술한 바와 같이 구성된 냉장고는 냉장고내의 온도와 설정온도의 차이에 따라 압축기(17)와 팬(14)이 온(ON)되어 고내(이하 냉장고내를 고내로 약칭한다)온도를 조정하게 되고, 또한 냉장고 도어스위치(18)의 온/오프에 의해 팬(14)이 정지/운전되어 고내온도를 조절하도록 되어 있다. 즉, 도어(6)의 열림 또는 닫힘등에 의한 저장물 및 외기의 유입으로 고내의 온도가 변화될 때 압축기(17)와 팬(14)이 운전되어 고내온도를 설정온도에 도달되도록 제어하고 있는데, 그 제어과정을 제2도에 나타내 보였다.In the refrigerator configured as described above, the compressor 17 and the fan 14 are turned on according to the difference between the temperature in the refrigerator and the set temperature, thereby adjusting the temperature in the refrigerator (hereinafter, the refrigerator is abbreviated as the refrigerator). The fan 14 is stopped / operated by turning on / off the refrigerator door switch 18 to adjust the internal temperature of the refrigerator. That is, the compressor 17 and the fan 14 are operated to control the internal temperature to reach the set temperature when the temperature in the refrigerator is changed due to the inflow of the storage and the outside air due to the opening or closing of the door 6. The control process is shown in FIG.

본 발명에 따른 냉장고의 제어방법은, 도어의 개폐에 따른 외기 및 저장물의 유입에 따른 고내 온도변화의 온도변화폭을 검출하여 최적의 온도조절과 증발기의 착상량을 줄이기 위해 냉기순환 송풍팬을 제어하는 것으로서, 압축기(17), 팬모터(24), 댐퍼(23), 증발기(13)등을 구비한 냉장고의 구성에 의해 실현된다. 또한, 본 발명은 냉장고 도어(6)의 개폐에 의해 동작하는 냉장고 도어스위치(18)와, 상기 도어스위치(6)의 동작으로부터 냉장고 도어(6)의 개폐를 검출하는 도어 개폐검출부(25)와, 냉장고내에 설치된 온도센서(20)와, 상기 온도센서(20)에 의해 냉장고내의 온도를 검출하는 온도검출부(28)와, 상기 도어개폐검출부(25)로부터 출력되는 신호에 의해 도어개방검출시간을 산출하는 도어개방시간 산출부(26)와, 상기 압축기(17), 냉기 순환 팬(14)이 부착된 팬모터(24), 댐퍼(23)를 구동제어하는 압축기 구동부(37), 팬모터 구동부(35), 댐퍼 구동부(35) 및 상기 각 검출부로부터 검출신호를 입력받아 연산처리하여 상기 각 구동부를 제어하는 제어부(36)를 포함하여 구성된 냉장고에서 구현된다.The control method of the refrigerator according to the present invention is to control the cold air circulating blower fan to detect the temperature change width of the temperature change in the high temperature according to the inflow of the outside air and the storage according to the opening and closing of the door and to reduce the amount of implantation of the evaporator. This is realized by the configuration of a refrigerator provided with a compressor 17, a fan motor 24, a damper 23, an evaporator 13, and the like. In addition, the present invention is a refrigerator door switch 18 that operates by opening and closing the refrigerator door 6, the door opening and closing detection unit 25 for detecting the opening and closing of the refrigerator door 6 from the operation of the door switch 6 and The door open detection time is determined by a temperature sensor 20 installed in the refrigerator, a temperature detector 28 detecting the temperature in the refrigerator by the temperature sensor 20, and a signal output from the door open / close detection unit 25.

상기와 같이 구성된 냉장고에 의해 실현되는 본 발명에 따른 냉장고의 제어방법의 작용 및 동작을 제1도 및 제3도를 참조하면서 살펴보면 다음과 같다.The operation and operation of the control method of the refrigerator according to the present invention realized by the refrigerator configured as described above will be described with reference to FIGS. 1 and 3.
먼저, 단계 101에서 온도센서(20)와 온도검출부(28)에 의해 고내온도가 검출되어 이 고내온도가 제어부(36)의 마이크로컨트롤러(미도시)에 저장되어 있는 설정온도와 비교된다(단계 103). 즉, 제어부(36)는 고내온도를 입력받아 사용자의 조작에 의해 설정된 설정온도와 연산조작에 의해 그 대소를 판별한다.First, in step 101, the temperature inside the refrigerator is detected by the temperature sensor 20 and the temperature detector 28, and the temperature inside the refrigerator is compared with a set temperature stored in a microcontroller (not shown) of the controller 36 (step 103). ). That is, the control unit 36 receives the high internal temperature, and determines the magnitude by the set temperature and arithmetic operation set by the user's operation.
단계 103에서 고내온도가 설정온도 이하로 판별되면, 단계 105에서 압축기(17), 팬모터(24), 댐퍼(23)가 오프되도록 제어부(36)는 압축기 구동부(37), 팬모터 구동부(35), 댐퍼 구동부(34)를 오프시켜 고내온도를 설정온도로 유지한다(단계 105). 그리고, 단계 103에서 고내온도가 설정온도 이상으로 판별되면, 일단 압축기(17)를 동작시키고(단계 107), 도어(6)가 열렸는지를 도어스위치(18)와 도어 개폐검출부(25)로 검출한다(단계 109).If the internal temperature is determined to be lower than or equal to the set temperature in step 103, the control unit 36 controls the compressor driving unit 37 and the fan motor driving unit 35 to turn off the compressor 17, the fan motor 24, and the damper 23 in step 105. ), The damper driver 34 is turned off to maintain the internal temperature at the set temperature (step 105). When the high temperature inside is determined to be equal to or higher than the set temperature in step 103, the compressor 17 is once operated (step 107), and the door switch 18 and the door open / close detection unit 25 detect whether the door 6 is opened. (Step 109).
상기 도어스위치(18)와 도어 개폐검출부(25)에 의해 상기 도어의 열림이 검출되면 냉기의 유출을 방지하기 위해 팬모터(24)를 오프시키고(단계 111), 상기 도어의 닫힘이 검출되면(단계 112), 단계(112)에서 팬모터(24)가 온 상태인지를 검출한다. 팬모터(24)가 온상태이면, 팬모터(24)를 온상태로 유지시키고 단계 101로 피이드백(feedback)하여 앞서의 단계를 반복한다. 그리고, 팬모터(24)가 오프상태이면 단계 114에서 고내온도와 설정온도를 산술연산하여 그 값, 즉 온도변화폭(Tw)을 산출하고, 온도변화폭(Tw)이 미리 설정되어 제어부(36)에 저장된 설정온도변화폭 이내인지를 판별한다(단계 114). 이 경우는 냉장고 도어(6)의 개폐에 의한 외기 및 저장물의 유입으로 고내온도가 크게 변화되어 증발기(13)에 착상이 많이 생길 수 있는 경우이다.When the door opening is detected by the door switch 18 and the door opening / closing detection unit 25, the fan motor 24 is turned off to prevent the leakage of cold air (step 111), and when the door closing is detected ( In step 112, the fan motor 24 is detected to be in an on state. If the fan motor 24 is on, the fan motor 24 is kept on and fed back to step 101 to repeat the preceding steps. When the fan motor 24 is in the off state, the arithmetic operation of the internal temperature and the set temperature is arithmetic in step 114 to calculate the value, that is, the temperature change width Tw, and the temperature change width Tw is set in advance to the controller 36. It is determined whether it is within the stored set temperature change range (step 114). In this case, the internal temperature of the refrigerator is greatly changed due to the inflow of the outside air and the stored goods by opening and closing of the refrigerator door 6, and thus, a lot of ideas may be generated in the evaporator 13.
만일, 온도변화폭(Tw)이 설정온도변화폭 이하이면, 단계 121에서 팬모터(24)를 온시키고 단계 101로 피이드백하여 앞서의 단계를 반복한다. 그리고, 온도변화폭(Tw)이 설정온도변화폭 이상이면, 단계 116에서 소정시간 지연후 단계 118, 119에서 소정시간동안 팬모터(24)를 온시키고 단계 114로 피이드백하여 앞서의 단계를 반복함으로써 증발기(13)에 착상되는 것을 최소화시킨다.If the temperature change width Tw is less than or equal to the set temperature change range, the fan motor 24 is turned on in step 121 and the feedback is returned to step 101 to repeat the previous step. If the temperature change width Tw is equal to or larger than the set temperature change range, the fan motor 24 is turned on for a predetermined time in steps 118 and 119 after a predetermined time delay in step 116 and fed back to step 114 to repeat the previous step. Minimize the idea of (13).
또한, 본 발명에 따른 냉장고의 제어방법은 상기 단계 109에서 도어(6)의 열림이 검출되면, 단계 111에서 팬모터(24)를 오프시키고, 단계 113에서 도어(6)의 열림시간(T)을 적산한다. 이는 냉장고 도어(6)의 개폐에 의한 외기 및 저장물의 유입 후 소정시간이 지났는데도 냉장고 도어(6)가 열려있으면 냉장고의 효율이 저하될 수 있기 때문이다. 따라서, 단계 115에서는 도어 열림시간(T)이 허용될 수 있는 한계 도어열림시간(Ts)보다 큰지를 비교한다. 만일 도어 열림시간(T)이 한계 도어열림시간(Ts)보다 크면, 단계 117에서 부져와 같은 경보수단으로 경보를 하여 냉장고 사용자에게 주의를 환기시키고, 도어 열림시간(T)이 한계 도어열림시간(Ts)보다 작으면, 단계 109로 피이드백하여 앞서의 단계를 수행한다.In addition, in the control method of the refrigerator according to the present invention, when the opening of the door 6 is detected in step 109, the fan motor 24 is turned off in step 111, and the opening time T of the door 6 in step 113. Is integrated. This is because the efficiency of the refrigerator may be reduced if the refrigerator door 6 is open even after a predetermined time has passed after the inflow of the outside air and the stored goods by opening and closing the refrigerator door 6. Therefore, in step 115, the door open time T is compared whether the threshold door open time Ts is greater than the allowable. If the door opening time T is greater than the limit door opening time Ts, the alarm is alerted by an alarm means such as a buzzer in step 117, and the door opening time T is the limit door opening time ( If less than Ts), feedback to step 109 to perform the previous step.
그리고, 도어열림시간(T)이 한계 도어열림시간(Ts)보다 커서 경보를 발하고 있는 중에 냉장고 도어(6)가 닫힐 수 있음으로, 이 경우를 대비하여 단계 109와 단계 112 사이에 경보중인 것을 중지시키는 경보중지 단계 110를 마련할 수 있다.In addition, since the refrigerator door 6 may be closed while the door opening time T is greater than the threshold door opening time Ts, and the alarm is issued, the alarm between the steps 109 and 112 is prepared. An alarm stop step 110 for stopping can be provided.
상술한 바와 같이 본 발명에 따른 냉장고의 제어방법은, 냉장고 도어의 개폐에 의한 외기 및 저장물의 유입에 따른 냉장고내 온도의 변화를 최적으로 조절할 수 있어 증발기의 착상량을 감소시킬 수 있는 이점을 제공한다.As described above, the control method of the refrigerator according to the present invention provides an advantage of reducing the amount of implantation of the evaporator by optimally controlling the change in the temperature of the refrigerator according to the inflow of the outside air and the stored matter by opening and closing the refrigerator door. do.
