Description

냉장고의 외기온도감지방법{Method for temperature detecting of a refrigerator}Method for temperature detecting of a refrigerator

본 발명은 냉장고의 외기온도감지방법에 관한 것으로, 더욱 상세하게는 압축기의 운전율과 현재온도조절상태에 기초하여, 외기온도를 판단하고 냉장고의 운전을 제어하는 외기온도감지방법에 관한 것이다.The present invention relates to a method for sensing an outside temperature of a refrigerator, and more particularly, to an outside temperature sensing method for determining an outside temperature and controlling the operation of a refrigerator based on an operation rate of a compressor and a current temperature control state.

냉장고의 운전제어에 효율성이 강조되면서, 냉장고 고내 온도와 더불어 냉장고 외부 온도가 냉장고의 운전제어에 이용되고 있다. 일 예로 여름과 겨울 냉장고의 고내 온도를 동일하게 제어하지 않고, 냉장고 외부온도에 따라서 고내 온도를 가변시켜서 제어하면, 냉장고의 운전에 보다 효율성을 기할 수 있다.As efficiency is emphasized in the operation control of the refrigerator, the outside temperature of the refrigerator as well as the inside temperature of the refrigerator is used for the operation control of the refrigerator. For example, by controlling the inside temperature of the refrigerator in accordance with the outside temperature of the refrigerator, rather than controlling the inside temperature of the refrigerator in the summer and winter, it can be more efficient in the operation of the refrigerator.

이것은 외부온도가 높을 경우, 고내 온도를 상대적으로 낮게 설정해야만 외부온도에 의해 빼앗기는 냉기를 보상할 수 있기 때문이다. 이와 상대적으로 외부 온도가 낮을 경우에는, 고내 온도를 높게 설정하여도 고내에 충분한 냉기 공급이 이루어질 수 있다. 따라서 냉장고의 주변 외기온도에 따라서 적절한 운전상태를 유지하게 되면, 보관 중인 음식물의 신선한 유지와 장시간 보관에 따른 효과를 얻을 수 있다.This is because when the outside temperature is high, the inside temperature of the high can be set relatively low to compensate for the cold air taken away by the outside temperature. On the other hand, when the external temperature is low, even if the internal temperature is set high, sufficient cold air can be supplied to the internal air. Therefore, if the proper operating state is maintained according to the ambient air temperature of the refrigerator, it is possible to obtain the effect of keeping fresh food and storing for a long time.

이러한 외부온도에 따른 냉장고의 운전제어를 위해서 종래는 외부온도 검출을 위한 센서부를 구비하고 있다.In order to control the operation of the refrigerator according to the external temperature, the prior art includes a sensor unit for detecting the external temperature.

도 1은 종래 냉장고의 외부온도 감지를 위한 구성도이다.1 is a configuration diagram for sensing an external temperature of a conventional refrigerator.

종래의 냉장고는, 냉장고 주변의 외기온도를 감지하는 외기온도감지센서(도시하지 않음)로부터 측정된 외기온도를 입력하는 외기온도감지센서입력부(15)와, 상기 외기온도감지센서입력부(15)에서 입력된 외기온도를 인지하고, 냉장고 운전 제어에 이용하는 마이크로컴퓨터(10)를 포함하고 있다.In the conventional refrigerator, the outside air temperature sensor input unit 15 for inputting the outside air temperature measured by an outside air temperature sensor (not shown) for detecting the outside air temperature around the refrigerator, and the outside air temperature sensor input unit 15 It includes a microcomputer 10 that recognizes the input outside air temperature and uses the refrigerator for controlling the operation of the refrigerator.

또한, 종래의 냉장고는, 소비자로부터 선택된 고내온도를 입력하는 온도조절입력부(20)를 포함하며, 상기 온도조절입력부(20)로부터 입력된 고내온도는 마이크로컴퓨터(10)로 출력된다. 그리고 냉동실, 냉장실 온도를 감지하는 센서로부터 측정된 냉동실온도 및 냉장실온도를 입력하는 냉동, 냉장실온도감지센서입력부(25)와, 상기 온도감지센서입력부(25)의 출력은 마이크로컴퓨터(10)에 입력된다.In addition, the conventional refrigerator includes a temperature control input unit 20 for inputting the internal temperature selected by the consumer, and the internal temperature input from the temperature control input unit 20 is output to the microcomputer 10. In addition, the freezer and refrigerator compartment temperature sensor input unit 25 for inputting the freezer compartment temperature and the refrigerator compartment temperature measured by the sensor for detecting the freezer compartment and the refrigerator compartment temperature, and the output of the temperature sensor input unit 25 are input to the microcomputer 10. do.

따라서 마이크로컴퓨터(10)는, 외기온도감지센서입력부(15)로부터 읽어들인 외기온도와, 상기 온도조절입력부(20)를 통하여 소비자가 선택한 고내온도에 기초하여, 현재 조건에서의 최적고내온도를 설정하다. 그리고 설정된 최적고내온도에 따라서 압축기(35) 및 팬모터(40) 그리고 댐퍼(30)의 운전을 제어한다.Therefore, the microcomputer 10 sets the optimum internal temperature in the current condition based on the external air temperature read from the external air temperature sensor input unit 15 and the internal temperature selected by the consumer through the temperature control input unit 20. . Then, the operation of the compressor 35, the fan motor 40, and the damper 30 is controlled according to the set optimum internal temperature.

즉, 상기 마이크로컴퓨터(10)는, 냉동,냉장실온도감지센서입력부(25)로부터 감지된 온도가 설정된 적정고내온도보다 낮을 경우에는 상기 압축기(35) 및 팬모터(40)의 동작을 정지시킨다. 반대로 상기 냉동실, 냉장실온도감지센서입력부(25)로부터 감지된 온도가 설정된 적정고내온도보다 높을 경우에는 상기 압축기(35) 및 팬모터(40)를 구동시켜서 냉기가 발생되어 고내 순환되도록 제어한다.That is, the microcomputer 10 stops the operation of the compressor 35 and the fan motor 40 when the temperature detected by the freezing and freezing compartment temperature sensor input unit 25 is lower than the set proper internal temperature. On the contrary, when the temperature detected from the freezer compartment and the refrigerating compartment temperature sensor input unit 25 is higher than the set proper internal temperature, the compressor 35 and the fan motor 40 are driven to control the cold air to be generated and circulated in the refrigerator.

그리고 댐퍼(45)는, 상기 압축기(35)로부터 발생된 냉기를 냉동실 및 냉장실로 공급하는 냉기공급경로이고, 상기 댐퍼(45)의 개폐를 상기 마이크로컴퓨터(10)에서 제어하도록 하고 있다.The damper 45 is a cold air supply path for supplying the cool air generated from the compressor 35 to the freezing chamber and the refrigerating chamber, and the microcomputer 10 controls the opening and closing of the damper 45.

즉, 종래의 냉장고는, 외기온도감지센서로부터 검출한 외기온도를 냉장고의 운전제어를 위한 기초정보로 이용하고 있다. 따라서 외기온도 검출을 위한 센서를구비해야 하며, 상기 센서로부터 검출된 온도를 전기적신호로 변환하기 위한 구성 등을 더 구비해야만 한다.That is, the conventional refrigerator uses the outside air temperature detected by the outside air temperature sensor as basic information for operation control of the refrigerator. Therefore, a sensor for detecting outside temperature must be provided, and a configuration for converting the temperature detected from the sensor into an electrical signal must be further provided.

따라서 종래의 냉장고는, 외부온도 검출에 따른 센서부를 구비해야하므로, 제조비용의 상승을 초래할 수 있고, 더불어 외부온도 검출을 위한 센서부를 냉장고의 외부에 장착해야만 하는 문제점이 있었다.Therefore, since a conventional refrigerator must include a sensor unit according to an external temperature detection, it may cause an increase in manufacturing cost, and in addition, there is a problem in that a sensor unit for external temperature detection must be mounted outside the refrigerator.

따라서 본 발명의 목적은 외기온도감지센서를 구비하지 않고, 압축기의 운전율과 현재 냉장고의 온도조절상태를 판단하여, 냉장고의 외기온도를 감지할 수 있는 냉장고의 외기온도감지방법을 제공함에 있다.Accordingly, an object of the present invention is to provide a method for detecting an outside temperature of a refrigerator, which is capable of sensing the outside temperature of the refrigerator by determining an operation rate of the compressor and a temperature control state of the current refrigerator without providing an outside temperature sensor.

도 2는 본 발명에 따른 냉장고의 운전 제어를 위한 구성도이다.2 is a configuration diagram for the operation control of the refrigerator according to the present invention.

본 발명의 냉장고는, 소비자에 의해서 선택된 온도를 입력하는 온도조절입력부(120)를 포함한다. 그리고 냉동실, 냉장실 온도를 감지하는 센서(도시하지 않음)로부터 검출된 온도를 입력하는 냉동,냉장실온도감지센서입력부(125)를 포함한다. 상기 냉동,냉장실온도감지센서입력부(125)의 출력은 마이크로컴퓨터(110)에 입력된다.The refrigerator of the present invention includes a temperature control input unit 120 for inputting a temperature selected by a consumer. And a freezing and refrigerating compartment temperature detecting sensor input unit 125 for inputting a temperature detected by a sensor (not shown) for detecting a freezing compartment and a refrigerating compartment temperature. The output of the freezer and freezer compartment temperature sensor input unit 125 is input to the microcomputer 110.

그리고 본 발명의 냉장고는, 상기 마이크로컴퓨터(110)의 운전 제어에 의해서 동작하여 고내 순환될 냉기를 발생시키는 압축기(135)와, 상기 압축기(135)로부터 발생된 냉기를 고내 순환시키기 위한 팬모터(140)와, 상기 압축기(135)로부터 발생된 냉기를 냉동실 또는 냉장실 등으로 공급하는 냉기공급경로인 댐퍼(145)를 포함하고 있다. 상기 압축기(135)의 운전과 상기 팬모터(140)의 동작 그리고 상기 댐퍼(145)의 개폐동작은 상기 마이크로컴퓨터(110)의 제어에 의해서 이루어진다.In addition, the refrigerator of the present invention may be operated by the operation control of the microcomputer 110 to generate a cold air to be circulated in the refrigerator, and a fan motor for circulating the cold air generated from the compressor 135 ( 140 and a damper 145 which is a cold air supply path for supplying cold air generated from the compressor 135 to a freezing compartment or a refrigerating compartment. Operation of the compressor 135, operation of the fan motor 140, and opening / closing of the damper 145 are performed by the control of the microcomputer 110.

다음은 상기 구성으로 이루어진 본 발명에 따른 냉장고의 외기온도감지를 위한 동작과정에 대해서 설명한다.Next will be described the operation process for detecting the outside temperature of the refrigerator according to the present invention having the above configuration.

마이크로컴퓨터(110)는, 상기 온도조절입력부(120)를 통하여 소비자가 설정한 고내온도를 입력한다. 그리고 냉동,냉장실 온도감지센서입력부(125)로부터 냉장실온도와 냉동실온도를 읽어들인다(제 200 단계).The microcomputer 110 inputs the internal temperature set by the consumer through the temperature control input unit 120. The refrigerator compartment temperature and the freezer compartment temperature are read from the freezer and refrigerator compartment temperature sensor input unit 125 (step 200).

상기 제 200 단계에서 읽어들인 냉동실, 냉장실온도가 상기 소비자가 설정한 고내온도보다 높을 경우, 그 이하 조건이 만족되도록 상기 압축기(135),팬모터(140), 댐퍼(145)를 구동시킨다(제 210 단계).When the freezer compartment and the refrigerating compartment temperature read in step 200 are higher than the internal temperature set by the consumer, the compressor 135, the fan motor 140, and the damper 145 are driven to satisfy the following conditions (the second stage). Step 210).

상기 제 210 단계에 의해서 압축기의 운전이 이루어지면, 압축기의 운전시간을 계산한다(제 220 단계, 제 225 단계). 즉, 상기 제 225 단계는, 압축기가 정지상태에 있다가 구동을 시작했을때, 압축기의 구동시간을 산출하는 과정이다.When the operation of the compressor is performed by the step 210, the operation time of the compressor is calculated (step 220 and step 225). That is, step 225 is a process of calculating the driving time of the compressor when the compressor is stopped and starts to drive.

만일, 상기 제 200 단계에서 읽어들인 냉동실, 냉장실온도가 상기 소비자가 설정한 고내온도보다 낮을 경우, 압축기를 포함한 부하구동부들의 동작을 오프상태로 제어한다(제 215 단계).If the freezer compartment and the refrigerating compartment temperature read in step 200 are lower than the internal temperature set by the consumer, the operation of the load driving units including the compressor is controlled to be turned off (step 215).

상기 제 215 단계에 의하여 압축기가 오프되면, 압축기의 오프시간을 계산한다(제 220 단계, 제 230 단계). 즉, 상기 제 230 단계는, 압축기가 구동상태에 있다가 정지되었을때, 압축기의 오프시간을 산출하는 과정이다.When the compressor is turned off by the step 215, the off time of the compressor is calculated (step 220 and step 230). That is, step 230 is a process of calculating an off time of the compressor when the compressor is in a driving state and stopped.

상기와 같은 과정으로 상기 제 225 단계는, 압축기(135)의 동작시간을 계산한다. 그리고 제 230 단계는, 압축기(135)의 오프시간을 계산한다. 이러한 과정에 의해서 압축기의 온시간이 계산되고, 오프시간이 계산되면, 압축기의 운전 1주기가 경과된다(제 235 단계).In step 225, the operation time of the compressor 135 is calculated. In operation 230, the off time of the compressor 135 is calculated. When the on time of the compressor is calculated by this process, and the off time is calculated, one cycle of operation of the compressor is elapsed (step 235).

상기 마이크로컴퓨터(110)는, 상기 압축기의 운전시간과 오프시간을 이용하여 압축기의 운전율을 산출한다(제 240 단계).The microcomputer 110 calculates an operation rate of the compressor using the operation time and the off time of the compressor (step 240).

상기 압축기의 운전율은 도 4에 도시하고 있는 바와 같이, 온시간/(온시간+오프시간) * 100에 의해서 산출된다.As shown in Fig. 4, the operation rate of the compressor is calculated by the on time / (on time + off time) * 100.

이때 산출되는 압축기의 운전율은, 소비자가 선택한 상태 즉, 상기 온도조절입력부(120)로부터 입력된 온도조절상태(약,적,강)에 따라서 다르게 되고, 강 > 적> 약의 순서로 운전율이 높아진다.The operation rate of the compressor calculated at this time is changed according to the state selected by the consumer, that is, the temperature control state (weak, red, strong) input from the temperature control input unit 120, and the operation rate in the order of strong> red> weak. Is higher.

즉, 상기 온도조절입력부(120)로부터 "강"의 상태가 선택되었을때, 압축기의 온시간이 길어지게 되고, 상기 온도조절입력부(120)로부터 "약"의 상태가 선택되었을때, 압축기의 온시간은 짧아지게 된다. 따라서 상기 압축기의 온시간이 길어지는 "강"의 상태일때, 압축기의 운전율은 높게 나타난다.That is, when the state of "strong" is selected from the temperature control input unit 120, the on time of the compressor is long, and when the state of "weak" is selected from the temperature control input unit 120, the ON of the compressor The time is shortened. Therefore, when the on time of the compressor is in the "strong" state, the operating rate of the compressor is high.

또한, 같은 온도조절상태에서라도 냉장고 외부의 온도상태(저온,상온,고온)에 따라서 저온에서 고온으로 갈수록 상기 운전율은 높게 나타난다. 이것은, 냉장고 외부온도가 높을수록 고내 냉기발생량을 더 필요로 하므로, 압축기의 운전시간이 길어지기 때문이다.In addition, even in the same temperature control state, the operation rate is higher from low temperature to high temperature according to the temperature conditions (low temperature, room temperature, high temperature) outside the refrigerator. This is because the higher the outside temperature of the refrigerator, the higher the amount of cold air generated in the refrigerator, and thus the longer the operation time of the compressor.

상기 제 240 단계에서 현재 온도조절상태에 따라서 압축기의 운전율이 계산되면, 마이크로컴퓨터(110)는 소비자가 설정한 온도조절입력부(120)의 온도조절상태를 판단한다(제 245 단계).When the operation rate of the compressor is calculated according to the current temperature control state in step 240, the microcomputer 110 determines the temperature control state of the temperature control input unit 120 set by the consumer (step 245).

그리고 상기 제 245 단계에서 판단된 현재온도조절상태와, 상기 제 240 단계에서 산출된 운전율을 이용하여 현재의 외기온도를 판단한다(제 250 단계). 즉, 상기 마이크로컴퓨터(110)는 내부의 메모리에 운전율과 현재온도조절상태에 따른 적절한 외기온도 특성을 저장하고 있어야 한다.The current outside temperature is determined using the current temperature control state determined in step 245 and the operation rate calculated in step 240 (step 250). That is, the microcomputer 110 should store the appropriate ambient temperature characteristics according to the operation rate and the current temperature control state in the internal memory.

즉, 냉장고의 경우, 저온, 상온, 고온 상태에서 각 온도조절상태에 따라 운전율이 도 5에 도시되고 있는 바와 같이 다르게 나타난다. 이러한 운전율을 가지고 각각의 온도조절상태에 따라서 냉장고의 외기온도를 판단하는 것이 가능하다. 따라서 상기 산출된 운전율과 현재온도조절상태에 따라서 적절한 외기온도를 판단하는 것이다.That is, in the case of the refrigerator, the operation rate is different as shown in FIG. 5 according to each temperature control state in the low temperature, room temperature, and high temperature state. With this operation rate, it is possible to determine the outside air temperature of the refrigerator according to each temperature control state. Therefore, the appropriate outside air temperature is determined according to the calculated operation rate and the present temperature control state.

이렇게 판단된 외기온도 및 상기 현재온도조절상태에 따라서 마이크로컴퓨터(110)는 적절한 운전상태를 설정하고(제 255 단계), 그에 따른 운전제어를 수행한다.According to the determined outdoor temperature and the present temperature control state, the microcomputer 110 sets an appropriate operation state (step 255), and performs the operation control accordingly.

이상 설명한 바와 같이 본 발명에 따른 냉장고의 외기온도감지방법은, 압축기의 운전율과 냉장고의 온도조절상태에 따라서 판단한다. 따라서 본 발명은 냉장고의 외기온도 검출을 위한 별도의 온도 센서가 필요없으며, 온도 센서 장착에 따른 번거로움도 없앨 수 있는 효과가 있다.As described above, the outdoor temperature sensing method of the refrigerator according to the present invention is determined according to the operation rate of the compressor and the temperature control state of the refrigerator. Therefore, the present invention does not need a separate temperature sensor for detecting the outside temperature of the refrigerator, there is an effect that can be eliminated the hassle of mounting the temperature sensor.
