본 발명은 냉장고의 쾌속 냉장제어방법에 관한 것으로, 특히 냉장실에 투입된 식품을 단시간내에 냉각시켜 원하는 목적에 따라 이용할 수 있도록 함과 동시에 기존에 저장되어 있던 식품은 얼지 않도록 해준 냉장고의 쾌속 냉장제어방법에 관한 것이다.The present invention relates to a fast refrigeration control method of the refrigerator, and in particular, to a fast refrigeration control method of the refrigerator which allows the food put into the refrigerating compartment to be cooled in a short time so that it can be used according to a desired purpose and not to freeze the previously stored food. It is about.

종래의 냉장고는 냉장실의 식품을 일정온도로 냉각시키기 위해서는 일정시간을 필요로 하는데 만약, 사용자가 급히 식품을 냉각시키고자 할때에는 별다른 방법이 없기 때문에 냉장실에 두고 냉장실 설정온도를 최대한 낮게 설정하여 주고 오랜시간을 기다려야만 되거나, 시간을 단축하기 위해 냉장실에 넣고 냉각시키는 경우가 있으나, 이는 식품이 얼게되는 문제점이 있어 왔다.Conventional refrigerators require a certain time to cool the food in the fridge to a certain temperature. If the user wants to cool the food in a hurry, there is no way, so set it in the fridge as low as possible and In order to shorten the time, or in order to shorten the time to cool in the refrigerating chamber, this has been a problem that the food is frozen.

본 발명의 목적은 상기 문제점을 해결하기 위하여 안출된 것으로, 쾌속냉장기능을 마련하여 쾌속 냉장 명령시 압축기, 팬, 댐퍼의 구동을 적절히 제어하여 일정시간 쾌속운전을 진행함으로써 투입된 식품을 쾌속으로 냉장시켜 주되, 이미 저장되어 있던 식품은 얼지 않도록 해준 냉장고의 쾌속 냉장제어방법을 제공함에 있다.An object of the present invention is to solve the above problems, by providing a rapid refrigeration function to properly control the operation of the compressor, fan, and damper during the rapid refrigeration command to perform the rapid operation for a certain time to refrigerated food quickly However, it is to provide a rapid refrigeration control method of the refrigerator that prevents the frozen food is already stored.

이하, 첨부된 도면에 의거하여 본 발명을 설명한다.Hereinafter, the present invention will be described with reference to the accompanying drawings.

제1도는 본 발명이 적용되는 냉장고의 회로도를 나타낸 것으로, 본 발명이 구동 프로그램이 내장된 원칩 마이크로 컴퓨터인 제어수단(1)의 입력포트(PI1)에는 저항(R1), (R2), 쾌속스위치(SW)로 구성된 쾌속키 입력수단(2)이 접속되어, 상기 쾌속스위치(SW)의 온(ON) 신호와 더불어 제어수단(1)의 포트(PI1)로 입력되어 로우신호로 쾌속냉장기능이 수행된다.1 is a circuit diagram of a refrigerator to which the present invention is applied. The present invention includes a resistor (R 1 ), (R 2 ) at an input port (PI 1 ) of a control means (1), which is a one-chip microcomputer with a built-in driving program. And a quick key input means (2) consisting of a quick switch (SW) is connected to the port (PI 1 ) of the control means (1) together with the ON signal of the quick switch (SW) and a low signal. Rapid refrigeration function is performed.

또한, 제어수단(1)의 입력포트(PI2)에는 냉장실의 소정개소에 설치되어 냉장실의 온도를 검출하는 써미스터(TH), 저항(R5), (R6)으로 구성된 냉장실 온도감지수단(4)이 접속되어 상기 써미스터(TH)가 냉장실의 온도를 감지하면 저항변화로 저항(R5)과의 분압에 따른 일정전압이 저항(R6)을 통해 제어수단(1)의 포트(PI2)로 입력됨으로써 제어수단(1)을 냉장실의 온도를 인식하며, 제어수단(1)의 출력포트(PO3)에는 저항(R3), (R4), 쾌속램프(LED) 및 트랜지스터(Q1)로 구성된 쾌속운전표시수단(3)이 접속되어, 상기 제어수단(1)이 포트(PO3)로 하이신호를 출력하면 트랜지스터(Q1)가 턴온되어 쾌속램프(LED)는 점등된다.In addition, the input port PI 2 of the control means 1 is installed in a predetermined part of the refrigerating compartment and is equipped with a thermistor TH for detecting the temperature of the refrigerating compartment, resistance R 5 , and a refrigerating compartment temperature sensing means (R 6 ) ( 4) is connected and the thermistor (TH) detects the temperature of the refrigerating chamber, the constant voltage according to the partial pressure with the resistor (R 5 ) due to the resistance change through the resistor (R 6 ) port (PI 2 of the control means 1) The control means 1 recognizes the temperature of the refrigerating compartment by inputting the control means 1, and the output ports PO 3 of the control means 1 have resistors R 3 , R 4 , rapid ramps, and transistors Q. When the quick operation display means 3 composed of 1 ) is connected, and the control means 1 outputs a high signal to the port PO 3 , the transistor Q 1 is turned on and the rapid ramp LED is turned on.

또한, 출력포트(PO1), (PO2)에는 저항(R10∼R17), 트랜지스터(Q4∼Q9), 댐퍼모터(DM)로 구성된 댐퍼구동수단(5)이 접속되어, 포트(PO1), (PO2)로의 제어된 출력에 의하여 댐퍼모터(DM)를 좌, 우로 구동시켜 주어 댐퍼(DP)의 개폐를 제어한다. 이때의 과정을 살펴보면, 출력포트(PO1), (PO2)로 각각 로우신호 및 하이신호가 출력되면 저항(R12)을 통해 트랜지스터(Q4)의 베이스에 저전위가 인가되어 트랜지스터(Q4)는 턴 오프되며 동시에 트랜지스터(Q5)의 베이스에도 저항(R11)을 통해 고전위가 인가되어 트랜지스터(Q5)도 턴 오프되며, 저항(R13)을 통해 흐르는 저전위가 트랜지스터(Q6)를 역시 턴 오프시킨다. 또한, 포트(PO2)로 출력된 하이신호는 저항(R16)을 통해 트랜지스터(Q7)를 턴온시키며 그 컬렉터 단에 저전위가 인가되어 트랜지스터(Q8)도 턴 온되어 그 컬렉터 전류가 댐퍼모터(DM)의 한 단자에 가해짐과 동시에 저항(R17)을 통해 트랜지스터(Q9)가 턴온되므로, 상기 트랜지스터(Q8)의 컬렉터 전류는 댐퍼모터(DM)를 통해 트랜지스터(Q9)의 에미터 접지로 흐르게 되어 댐퍼모터(DM)는 한 방향으로 회전구동하게 되며 댐퍼(DP)는 개방된다.In addition, the output ports PO 1 and PO 2 are connected with damper driving means 5 composed of resistors R 10 to R 17 , transistors Q 4 to Q 9 , and damper motor DM. The damper motor DM is driven left and right by the controlled outputs to PO 1 and PO 2 to control the opening and closing of the damper DP. In this case, when the low signal and the high signal are respectively output to the output ports PO 1 and PO 2 , a low potential is applied to the base of the transistor Q 4 through the resistor R 12 , so that the transistor Q 4 ) is turned off and at the same time a high potential is applied to the base of the transistor Q 5 through the resistor R 11 so that the transistor Q 5 is also turned off, and the low potential flowing through the resistor R 13 becomes the transistor ( Q 6 ) is also turned off. In addition, the high signal outputted to the port PO 2 turns on the transistor Q 7 through the resistor R 16 , and a low potential is applied to the collector terminal thereof, so that the transistor Q 8 is turned on so that the collector current is turned on. Since the transistor Q 9 is turned on through the resistor R 17 while being applied to one terminal of the damper motor DM, the collector current of the transistor Q 8 is transferred to the transistor Q 9 through the damper motor DM. The damper motor DM is rotated in one direction and the damper DP is opened.

한편, 출력포트(PO1), (PO2)로 각각 하이 및 로우신호를 출력하면 전술한 과정과는 상반되게 트랜지스터(Q7), (Q8), (Q9)는 턴 오프되며, 트랜지스터(Q4), (Q5), (Q6)는 턴온되어 전류가 상기 트랜지스터(Q5)의 컬렉터에서 댐퍼모터(DM)를 통하여 트랜지스터(Q6)의 에미터 접지로 흐르게 되므로 댐퍼모터(DM)는 전술한 방향과는 반대방향으로 회전구동하게 되며 댐퍼(DP)는 폐쇄되게 된다.On the other hand, when the high and low signals are output to the output ports PO 1 and PO 2 , respectively, the transistors Q 7 , Q 8 , and Q 9 are turned off in contrast to the above-described process. Q 4 , Q 5 , and Q 6 are turned on so that current flows from the collector of transistor Q 5 through the damper motor DM to the emitter ground of transistor Q 6 . DM) rotates in the opposite direction to the above-described direction and the damper DP is closed.

이와같이 출력포트(PO1), (PO2)로의 제어된 출력은 댐퍼의 개폐를 담당한다.As such, the controlled outputs to the output ports PO 1 and PO 2 are responsible for opening and closing the damper.

또한, 상기 제어수단(1)의 출력포트(PO5)에는 저항(R7∼R9), 트랜지스터(Q2), (Q3), 릴레이(RY1), 압축기(CP)로 구성된 압축기 구동수단(6)이 접속되어, 이 포트(PO5)로 출력된 로우신호는 저항(R8)을 통해 트랜지스터(Q2)를 턴온시키며, 그 에미터 신호가 트랜지스터(Q3)를 턴온시키어 이 트랜지스터(Q3)의 컬렉터 전류가 릴레이(RY1)의 코일을 통해 접지로 흐르게 되어 그 스위치가 온됨과 동시에 전원(AC)이 압축기(CP)에 가해져 압축기(CP)는 구동하게 된다.In addition, the output port PO 5 of the control means 1 drives a compressor including resistors R 7 to R 9 , transistors Q 2 , Q 3 , relay RY 1 , and compressor CP. The means 6 is connected and the low signal output to this port PO 5 turns on transistor Q 2 via a resistor R 8 , the emitter signal of which turns on transistor Q 3 . The collector current of transistor Q 3 flows to the ground through the coil of relay RY 1 , the switch is turned on and power AC is applied to compressor CP to drive compressor CP.

또한, 제어수단(1)의 출력포트(PO4)에는 저항(R18∼R20), 트랜지스터(Q10), (Q11), 릴레이(RY2), 팸모터(FM) 및 팬(FAN)으로 구성된 팬 구동수단(7)이 접속되어 이 포트(PO4)로 출력하면 트랜지스터(Q10), (Q11)가 턴 온되어 릴레이(RY2)가 온되고 동시에 팬 모터(FM)에 전원(AC)이 인가되어 팬(FAN)은 구동하게 된다.In addition, the output port PO 4 of the control means 1 has a resistor R 18 to R 20 , a transistor Q 10 , a Q 11 , a relay RY 2 , a fem motor FM and a fan FAN. When the fan drive means (7) consisting of) is connected and output to this port (PO 4 ), the transistors (Q 10 ) and (Q 11 ) are turned on so that the relay (RY 2 ) is turned on and at the same time to the fan motor (FM). The power AC is applied to drive the fan FAN.

제2도는 본 발명에 따른 쾌속 냉장 운전시의 냉장실 온도 변화를 나타내는 곡선으로, 냉장실의 온도는 통상적으로 몇 단계(예를 들어 「강」, 「중」, 「약」)의 온도대로 설정하여 줄 수 있고, 그 설정된 온도 범위를 유지하도록 팬(FAN)가 댐퍼(DP)가 적절히 구동된다.2 is a curve showing a change in the temperature of the refrigerator compartment during the rapid refrigeration operation according to the present invention, the temperature of the refrigerator compartment is usually set to a temperature of several steps (for example, "strong", "medium", "weak"). The fan FAN is appropriately driven so as to maintain the set temperature range.

우선, 시간(t0∼t1)에서 평상시의 어떤 냉장실 온도를 유지하고 있다가 시간(t1)에서 쾌속스위치(SW)를 온하여 쾌속냉장기능이 수행되면, 이미 설정되어 있는 쾌속운전시간(t1∼t4) 동안 쾌속냉장기능이 수행되는데, 이때 상기 시간(t1)에서는 압축기(CP), 팬(FAN)을 구동시키고, 댐퍼(DP)를 개방시켜 냉장실의 온도를 임의의 쾌속설정온도(예를 들어 -3℃∼0℃)로 떨어뜨려준다. 또한, 상기 쾌속설정온도로 이미 설정되어 있는 쾌속온도 유지시간(t2∼t3) 동안을 유지한다. 상기 쾌속온도 유지시간(t2∼t3)은 많은 실험에 의하여 산출된 데이터로 기존에 냉장실에 저장되어 있는 식품이 얼지 않는 범위의 시간으로 설정(예를들어 10분)되어 있다.When the first, the time (t 0 ~t 1) in maintaining the temperature of the refrigerating compartment which normally would have to turn on the rapid switch (SW) at time (t 1) rapid refrigeration function is carried out, rapid operating time has already been set ( Quick refrigeration function is performed during t 1 to t 4 ). At this time (t 1 ), the compressor (CP) and the fan (FAN) are driven and the damper (DP) is opened to set the temperature of the refrigerating chamber at an arbitrary rapid speed. Drop it to a temperature (eg -3 ° C to 0 ° C). Furthermore, it maintains for the rapid temperature holding time t 2 -t 3 which is already set to the rapid speed setting temperature. The rapid temperature holding time (t 2 to t 3 ) is data calculated by many experiments and is set to a time within a range in which the food stored in the refrigerating chamber is not frozen (for example, 10 minutes).

이와같은 쾌속온도 유지시간(t2∼t3)이 경과되고, 상기 쾌속운전시간이 경과되지 않았다면, 상기 남은 쾌속운전시간 동안 냉장실의 온도를 냉장실「강」온도로 유지한다.If such rapid temperature holding time t 2 to t 3 has elapsed and the rapid operating time has not elapsed, the temperature of the refrigerating chamber is maintained at the refrigerating chamber "strong" temperature for the remaining rapid operating time.

그리고, 상기 쾌속운전시간이 종료되는 시간(t4)에서 처음 설정된 평상시 냉장실 온도로 다시 복귀되는 것이다.Then, at the time t 4 at which the rapid driving time is completed, the temperature is returned to the normal refrigerator temperature.

상기와 같은 구성을 가진 냉장고에 적용되는 본 발명을 제3도의 제어 흐름도를 참조하여 설명한다.The present invention applied to the refrigerator having the above configuration will be described with reference to the control flowchart of FIG.

냉장고에 전원(AC)을 인가하면, 우선, 제어수단(1)은 포트(PO3)로 쾌속운전표시수단(3)의 쾌속램프(LED)에 점등신호가 출력되고 있나를 판단한다(100단계). 이 판단 단계(100)에서 포트(PO3)로의 출력이 검출되면 포트(PI1)로 입력되는 쾌속스위치(SW)의 키입력신호를 검출한다(101단계). 여기서, 쾌속스위치(SW) 키입력이 검출되면 쾌속운전중지신호임을 인식하여 포트(PO3)로의 출력을 차단하여 쾌속램프(LED)를 소등시키고(102단계), 쾌속운전시간(t1∼t4)을 리세트시키고(103단계), 동시에 쾌속온도 유지시간(t2∼t3)도 리세트시키고(104단계), 통상의 운전상태로 진행한다(105단계).When the power source AC is applied to the refrigerator, first, the control means 1 determines whether a lighting signal is output to the quick lamp LED of the quick drive display means 3 through the port PO 3 (step 100). ). When the output to the port PO 3 is detected in the determination step 100, the key input signal of the rapid switch SW input to the port PI 1 is detected (step 101). Here, when the key switch SW is detected, it recognizes that it is a fast driving stop signal and cuts the output to the port PO 3 to turn off the quick lamp LED (step 102), and the fast driving time (t 1 to t). 4 ) is reset (step 103), and at the same time, the rapid temperature holding time (t 2 to t 3 ) is also reset (step 104), and the operation proceeds to the normal operation state (step 105).

한편, 상기 판단 단계(100)에서 쾌속램프(LED)가 소등상태이면 쾌속스위치(SW)의 키입력을 판별하되(106단계), 이때 키입력신호가 검출되지 않으면 쾌속냉장명령이 없는 것으로 인식하여 전술한 단계(102∼105)를 수행하게 된다.On the other hand, if the rapid lamp (LED) is turned off in the determination step 100, the key input of the quick switch (SW) is determined (step 106), and if the key input signal is not detected, it is recognized that there is no quick refrigeration command. Steps 102 to 105 described above are performed.

또한, 상기 판단 단계(106)에서 쾌속스위치(SW)의 키입력이 감지되거나, 상기 판단 단계(101)에서 쾌속스위치(SW)의 키입력이 검출되지 아니하면 쾌속냉장명령이 개시되었거나 쾌속냉장중이라 인식하여 쾌속램프(LED)에 점등신호를 출력한다(107단계).In addition, if the key input of the quick switch SW is detected in the determining step 106, or if the key input of the quick switch SW is not detected in the determining step 101, the quick refrigeration command is started or during rapid refrigeration. In operation 107, the controller outputs a lighting signal to the rapid ramp (LED).

따라서, 쾌속냉장운전은 수행되며, 이때 설정된 쾌속운전시간(t1∼t4)이 경과됐는가를 판단한다(108단계). 여기서 쾌속운전시간이 경과되었다고 판단되면 전술한 단계(102∼105)를 수행하게 되며, 쾌속운전시간이 경과되지 않았다면, 쾌속온도 유지시간(t2∼t3)이 경과되었는가를 판단하게 된다(109단계).Therefore, the rapid refrigeration operation is performed, and at this time, it is determined whether the set rapid operation time (t 1 to t 4 ) has elapsed (step 108). If it is determined that the rapid driving time has elapsed, the above-described steps 102 to 105 are performed. If the rapid driving time has not elapsed, it is determined whether the rapid temperature holding time t 2 to t 3 has elapsed (109). step).

상기 판단 단계(109)에서, 쾌속온도 유지시간이 경과되지 않았다면은, 현재 댐퍼(DP)가 개방상태인가 폐쇄상태인가를 포트(PO1), (PO2)로의 출력상태를 검출하여 검색하며(110단계), 댐퍼(DP)가 폐쇄되어 있을때에는 냉장실 온도와 쾌속설정온도를 비교 판단하여(111단계), 냉장실 온도가 쾌속설정온도보다 높으면 댐퍼(DP)를 개방하고, 팬(FAN)을 구동시켜 냉장실의 온도를 낮추어 주고, 상기 판단 단계(110)에서 댐퍼(DP)가 개방상태인 경우, 냉장실 온도와 쾌속설정온도를 비교판단하여(113단계), 냉장실 온도가 쾌속설정온도보다 낮다면 댐퍼(DP)를 폐쇄시킨다(114단계). 결국, 쾌속온도 유지시간 동안 냉장실 온도를 쾌속설정온도로 유지하기 위하여 댐퍼(DP)를 개폐하거나 팬(FAN)을 구동시키게 되는 것이다.In the determination step 109, if the rapid temperature holding time has not elapsed, an output state to the ports PO 1 and PO 2 is detected by searching whether the current damper DP is in an open state or a closed state ( Step 110), when the damper DP is closed, the refrigerator compartment temperature and the quick set temperature are compared and judged (step 111). If the refrigerator compartment temperature is higher than the quick set temperature, the damper DP is opened and the fan is driven. Lowering the temperature of the refrigerating compartment, and if the damper DP is open in the determination step 110, compares the refrigerating compartment temperature with the quick set temperature (step 113), and if the refrigerator compartment temperature is lower than the quick set temperature, the damper. Close the DP (step 114). As a result, the damper DP may be opened or closed or the fan FAN may be driven to maintain the refrigerating chamber temperature at the rapid setting temperature during the rapid temperature maintaining time.

한편, 상기 판단 단계(109)에서 쾌속온도 유지시간(t2∼t3)이 경과되었음이 판단되면, 댐퍼(dp)가 개방상태인가를 검출하여(115단계), 상기 댐퍼(DP)가 개방되었다면 냉장실 온도와 냉장실「강」온도를 서로 비교 판단하여(116단계), 냉장실 온도가 냉장실「강」온도 보다 낮다면 댐퍼(DP)를 폐쇄하고(119단계), 상기 판단 단계(115)에서 댐퍼(DP)가 폐쇄된 상태일때에도 냉장실 온도와 냉장실「강」온도를 비교 판단하여(117단계), 냉장실 온도가 냉장실「강」온도 보다 높음이 검출되면 댐퍼(DP)를 개방하고 팬(FAN)을 구동시킨다(118단계).On the other hand, if it is determined in step 109 that the rapid temperature holding time t 2 to t 3 has elapsed, it is detected whether the damper dp is in an open state (step 115), and the damper DP is opened. If the refrigerator compartment temperature and the refrigerating chamber "strong" temperature is compared to each other (step 116), if the refrigerator compartment temperature is lower than the refrigerating chamber "steel" temperature, the damper (DP) is closed (step 119), and the damper in the determination step 115 Even when the DP is closed, the refrigerator compartment temperature is determined by comparing the refrigerator compartment temperature with the refrigeration chamber temperature (step 117). If the refrigerator compartment temperature is detected to be higher than the refrigerator compartment temperature, the damper DP is opened and the fan is opened. (Step 118).

결국, 쾌속온도 유지시간이 경과되고, 남은 쾌속운전시간이 존재하면 냉장실 온도를 냉장실「강」온도로 유지하기 위하여 댐퍼(DP)를 개폐하거나 팬(FAN)을 구동시키는 것이다.As a result, when the rapid temperature holding time elapses and the remaining rapid operation time exists, the damper DP is opened or opened to drive the refrigerator compartment temperature at the refrigerator compartment "strong" temperature.

따라서, 냉장실은 급속한 쾌속냉장을 실행하게 되는 것이다.Therefore, the refrigerating chamber is to perform rapid rapid refrigeration.

이상에서와 같이 본 발명은 냉장고의 냉장실에 투입된 식품을 필요에 따라 단시간내에 급냉시켜 사용할 수 있을 뿐만 아니라 이때 식품이 얼게되는 현상을 배제한 유용한 발명이다.As described above, the present invention is a useful invention that can not only quench the food put into the refrigerator compartment of the refrigerator in a short time as needed, but also exclude the phenomenon of freezing the food.
