Abstract

PURPOSE: A controlling method of a fan in a refrigerating chamber is provided to improve cooling speed of a refrigerating chamber by resetting a driving on/off point of a refrigerating chamber sensor at initial operation of a refrigerator or when inputting overload. CONSTITUTION: A temperature sensed in a temperature sensor of a refrigerating chamber is decided to be a certain weak cooling sensing point or not. If the temperature is over the weak cooling sensing point, the driving on/off point is reset and operation is performed by high speed cooling mode. If the temperature is under the weak cooling sensing point, an R fan is decided to be driving or not. If the R fan is not driving, the on point of an R sensor is decided. If the point is driving on, the R fan is driven. If the R fan is driving, the driving off point of the R sensor is decided. If the point is driving off, the driving of the R fan is turned off. If the temperature is over 6°C, the refrigerating chamber starts to be operated by high speed cooling mode.

냉장실 팬 제어 방법.How to control your fridge fan.

본 발명은 냉장실 팬 제어방법에 관한 것으로서, 특히 냉장고의 초기 기동시나 과부하 투입시 냉장실 센서의 구동온/오프점을 재설정하여 냉장실의 냉각 속도를 향상시킬 수 있도록 하는 냉장실 팬 제어방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerating compartment fan control method, and more particularly, to a refrigerating compartment fan control method for resetting a driving on / off point of a refrigerating compartment sensor at an initial startup of an refrigerator or when an overload is applied.

일반적으로 냉장고는 냉각 사이클(Cooling cycle)을 이용하여 식품을 냉동 및 냉장 보관하는데 사용되는 가전제품으로, 압축기(Compressor)에서 고온, 고압으로 압축된 냉매가스를 응축기(Condenser)에서 외기와의 열 교환으로 액화시켜 리시버 드라이어(Receiver dryer)에서 여과한 뒤, 모세관(Capillary Tube)을 통해 저온, 저압의 액냉매로 단열 팽창시키게 된다.Generally, a refrigerator is a household appliance used to freeze and refrigerate food by using a cooling cycle. The refrigerator exchanges refrigerant gas, which has been compressed at high and high pressure in a compressor, to the outside air in a condenser. After liquefied by filtration in the receiver dryer (Receiver dryer), through the capillary tube (Capillary Tube) is adiabatic expansion with low-temperature, low-pressure liquid refrigerant.

특히, 간냉식(Fan-Cooling) 냉장고는 증발기(Evaporator)에서 팬(Fan)에 의해 순환되는 캐비넷 내의 고내(Cavity) 공기와 열을 교환시켜 흡수되는 냉매의 증발열에 의해 수납된 음식물을 냉동 및 냉장시키게 되고, 팬 및 압축기의 구동/정지 제어로서 온도 제어를 수행한다.In particular, a fan-cooling refrigerator exchanges heat with cavity air in a cabinet circulated by a fan in an evaporator to freeze and refrigerate food stored by evaporative heat of refrigerant absorbed. Temperature control is performed as the drive / stop control of the fan and the compressor.

한편, 증발기(Evaporator) 주위의 냉기를 팬에 의해 강제로 대류시켜 냉각시키는 이러한 간냉식(Fan-Cooling) 냉장고 중에서, 냉장실 온도 중심으로 온도 제어를 하는 냉장고는 냉동실에 하나의 팬을 구비하는데, 냉장실내에서 검출된 온도를 중심으로 냉기를 토출시키는 팬과, 가스 상태의 냉매를 액화시키기 위하여 저압저온 냉매 가스를 고압고온 냉매 가스로 변환시키는 압축기(Compressor)를 구동 제어하여 증발기 주위의 냉기를 냉동실 및 냉장실로 토출시켜서 냉장고의 온도를 적정 온도로 유지시킨다.On the other hand, among such fan-cooling refrigerators in which cold air around an evaporator is forced to convectively by a fan and cooled, a refrigerator having a temperature control centered on a refrigerator compartment temperature has one fan in a freezer compartment. A fan for discharging cold air around the detected temperature and a compressor for converting a low pressure low temperature refrigerant gas into a high pressure high temperature refrigerant gas in order to liquefy a gaseous refrigerant, thereby controlling the cold air around the evaporator in the freezer compartment and the refrigerator compartment The temperature of the refrigerator is maintained at an appropriate temperature.

부연 설명하면, 검출된 냉장실 온도가 기설정된 적정 상한 온도 이상이면 팬과 압축기를 구동 온 제어하고, 검출된 냉장실 온도가 기설정된 적정 하한 온도 이하이면 팬과 압축기를 구동 오프로 제어하여 냉장실 및 냉동실의 온도 제어를 수행한다.In detail, if the detected refrigerator compartment temperature is higher than or equal to a predetermined upper limit temperature, the fan and the compressor are driven on and controlled. If the detected refrigerator compartment temperature is lower than or equal to the preset lower limit temperature, the fan and the compressor are controlled to be driven off to control the refrigerator and the freezer compartment. Perform temperature control.

따라서, 냉장고에 과부하의 투입시 냉장실 온도센서가 감지한 온도가 약냉감지점, 즉 6℃이상일 경우 압축기를 강제로 구동하고 냉장실 온도센서 오프점에서 압축기를 구동 오프시키게 된다.Therefore, when the temperature detected by the refrigerating compartment temperature sensor at the time of injecting the overload into the refrigerator is weakly detected, that is, 6 ° C. or more, the compressor is forcibly driven and the compressor is turned off at the refrigerating compartment temperature sensor off point.

그런데, 이러한 냉장고의 제어방법은 부하가 냉각되는 속도가 느리기 때문에 냉각효율이 저하되고, 소비전력이 증가되는 문제점이 있다.However, the control method of the refrigerator has a problem that the cooling efficiency is lowered and the power consumption is increased because the load is cooled slowly.

본 발명은 상기와 같은 문제점을 해결하기 위하여 창출된 것으로써, 냉장고의 초기 기동시나 과부하 투입시 냉장실 센서의 구동온/오프점을 재설정하여 냉장실의 냉각 속도를 향상시킬 수 있도록 하는 냉장실 팬 제어방법을 제공하는데 있다.The present invention was created in order to solve the above problems, a refrigerator control method for refrigerating compartment to improve the cooling rate of the refrigerating compartment by resetting the drive on / off point of the refrigerating compartment sensor during the initial startup or overloading of the refrigerator. To provide.

이러한 본 발명 냉장실 팬 제어방법은, 냉장실 온도를 감지하는 냉장실 온도센서가 감지한 온도가 소정의 약냉 감지점 이상인지를 판단하는 단계와; 냉장실 온도가 소정의 약냉 감지점 이상일 경우 냉장실 온도센서의 구동온/오프점을 재설정하여 고속냉각 운전하는 단계를 포함하여 이루어진다.The refrigerator control method of the present invention comprises the steps of: determining whether a temperature detected by a refrigerating compartment temperature sensor detecting a refrigerating compartment temperature is above a predetermined weak cooling detection point; If the refrigerating compartment temperature is more than the predetermined weak cooling detection point is made by the step of resetting the drive on / off point of the refrigerating compartment temperature sensor comprises a high-speed cooling operation.

상술된 본 발명의 특징에 의하면, 본 발명 냉장실 팬 제어 방법은, 냉장고의 초기 기동시나 과부하 투입시 냉장실 센서의 구동온/오프점을 재설정하여 냉장실의 냉각 속도를 향상시킬 수 있게 된다.According to the above-described feature of the present invention, the refrigerating compartment fan control method of the present invention can improve the cooling rate of the refrigerating compartment by resetting the driving on / off point of the refrigerating compartment sensor when the refrigerator is initially started or when an overload is applied.

이하, 첨부된 도면을 참조하여 본 발명 냉장실 팬 제어방법에 대해 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail the refrigerator control method of the present invention.

도1은 본 발명에 따른 냉장실 팬 제어방법에 대한 블럭도로서, 냉장실 온도센서(10), 마이컴(20), 팬 구동부(30), F팬(40), 압축기 구동부(50), 압축기(60)를 포함한다.1 is a block diagram of a refrigerator control method according to the present invention, the refrigerator compartment temperature sensor 10, the microcomputer 20, the fan drive unit 30, F fan 40, compressor drive unit 50, compressor 60 ).

이러한 구성에 있어서, 냉장실 온도센서는(10) 냉장실 내의 소정 위치에 설치되어 R센서에 의해 냉장실의 실내 온도를 검출하여 온도 검출 신호를 후출하는 마이컴(20)의 A/D(Analog to Digital)포트로 인가한다.In such a configuration, the refrigerating compartment temperature sensor (10) is installed at a predetermined position in the refrigerating compartment and detects the room temperature of the refrigerating compartment by the R sensor to return the temperature detection signal (A / D (Analog to Digital) of the microcomputer 20). Apply to the port.

그리고, 마이컴(20)은 냉장실 온도센서(10)로부터 A/D포트를 통하여 인가되는 온도 검출 신호에 의거하여 R팬(40)을 제어한다.The microcomputer 20 controls the R fan 40 based on a temperature detection signal applied from the refrigerating chamber temperature sensor 10 through the A / D port.

냉장실 온도센서(10)가 감지한 냉장실 온도가 6℃이하일 경우 냉장실 팬(40)의 구동여부를 판단하여 구동온점일 경우 냉장실 팬(40)을 구동시키고, 구동오프점일 경우 냉장실 팬(40)을 오프시키는 제어신호를 출력한다.When the refrigerator compartment temperature detected by the refrigerator compartment temperature sensor 10 is 6 ° C. or less, it is determined whether the refrigerator compartment fan 40 is driven and the refrigerator compartment fan 40 is driven when the driving temperature is at a driving point, and when the refrigerator compartment temperature is driven off, the refrigerator compartment fan 40 is operated. Outputs a control signal to turn off.

또한, 냉장실 온도가 약냉감지점, 즉 6℃이상일 경우에는 냉장실 고속 냉각 모드로 돌입하여 재설정된 냉장실 구동온/오프점에 따라 냉장실 온도 제어를 수행한다.In addition, when the refrigerating chamber temperature is a weak cooling detection point, that is, 6 ° C. or more, the refrigerating chamber high temperature cooling mode is entered and the refrigerating chamber temperature control is performed according to the refrigerating compartment driving on / off point.

그리고, 팬구동부(30)는 구동 소자 및 릴레이 등을 이용하여 마이컴(20)의 제어에 의거하여 소정 구동 신호를 R팬(40)으로 출력하며, R팬(40)은 팬구동부(30)로부터의 구동 신호에 의거하여 구동되어 도시 생략된 증발기 주변의 냉기를 냉동실과 냉장실로 토출시킨다.The fan driver 30 outputs a predetermined drive signal to the R fan 40 under the control of the microcomputer 20 using a drive element, a relay, and the like, and the R fan 40 is driven from the fan driver 30. Driven on the basis of the drive signal of to discharge the cold air around the evaporator (not shown) to the freezer compartment and the refrigerating compartment.

또한, 압축기 구동부(50)는 구동 소자 및 릴레이 등을 이용하여 마이컴(20)의 제어에 의거하여 소정 구동 신호를 압축기(60)로 출력하며, 압축기(60)는 상술한 바 있는 냉동 사이클에서 기화된 냉매를 다시 액화시켜 재사용하기 위한 준비 단계로 도시 생략된 증발기로부터의 저온저압의 냉매 가스를 고온고압의 냉매 가스로 압축 변환하여 도시 생략된 응축기로 출력한다.In addition, the compressor driver 50 outputs a predetermined drive signal to the compressor 60 under the control of the microcomputer 20 using a driving element, a relay, and the like, and the compressor 60 is vaporized in the aforementioned refrigeration cycle. As a preliminary step for liquefying and reusing the used refrigerant, the refrigerant gas of low temperature and low pressure from the evaporator, not shown, is compressed and converted into a refrigerant gas of high temperature and high pressure, and outputted to a condenser, not shown.

다음에, 상술한 구성부를 포함하는 본 발명의 바람직한 실시예에 따른 냉장실 팬 제어 과정을 첨부한 도2의 흐름도를 참조하여 상세히 설명한다.Next, the refrigerator compartment fan control process according to the preferred embodiment of the present invention including the aforementioned components will be described in detail with reference to the flowchart of FIG. 2.

먼저, 냉장실의 온도를 검출하는 냉장실 온도 센서는 냉장실의 온도를 검출하여 냉장실 온도 검출 신호를(일반적으로 직류 레벨의 전압값) 마이컴의 A/D포트로 인가하게 된다.First, the refrigerating compartment temperature sensor detecting the temperature of the refrigerating compartment detects the temperature of the refrigerating compartment and applies a refrigerating compartment temperature detection signal (generally, a DC level voltage value) to the A / D port of the microcomputer.

다음에, 마이컴은 냉장실 온도가 약냉 감지점, 즉 6℃ 이상인지를 판단하여(단계100) 이하일 경우에는 R팬이 구동상태인지를 판단한다.(단계200)Next, the microcomputer determines whether the temperature of the refrigerating compartment is a weak cooling detection point, that is, 6 ° C. or more (step 100).

이어서, R팬이 구동상태가 아닐 경우 R센서 구동 온점인지를 판단하여(단계300) 구동 온점일 경우 R팬을 구동시키게 된다.(단계400)Subsequently, if the R fan is not in the driving state, it is determined whether the R sensor is driven on (step 300), and if the R fan is driven, the R fan is driven.

그리고, R팬이 구동상태일 경우 R센서 구동 오프점인지를 판단하여(단계500) 구동 오프점일 경우 R팬을 구동 오프시키게 된다.(단계600)When the R fan is in the driving state, it is determined whether it is the R sensor driving off point (step 500). If the R fan is the driving off point, the R fan is driven off.

한편, 냉장실 온도센서가 감지한 온도가 6℃상일 경우 냉장실 고속냉각 모드로 돌입하게 된다.(단계700)On the other hand, if the temperature detected by the refrigerator compartment temperature sensor is 6 ℃ phase enters the refrigerator compartment fast cooling mode (step 700).

따라서, 초기 기동시 또는 통상제어 중에 냉장실 센서가 감지한 냉장실 온도가 6℃, 즉 약냉 감지점을 경우 고속냉각 모드로 돌입하여 새롭게 설정된 냉장실 센서 구동온/오프점 패턴에 따라 냉장실의 온도 제어를 수행한다.Therefore, when the refrigerator compartment temperature detected by the refrigerator compartment sensor at the initial start-up or during normal control is 6 ° C, that is, a weakly cold detection point, the refrigerator enters the high-speed cooling mode and controls the temperature of the refrigerator compartment according to the newly set refrigerator compartment sensor on / off point pattern. do.

냉장실 센서의 구동온/오프점 변경 패턴 테이블은, 도3에 도시된 것과 같다.The drive on / off point change pattern table of the refrigerator compartment sensor is as shown in FIG.

따라서, 냉장실의 부하 냉각 속도를 향상시킬 수 있게 된다.Therefore, the load cooling rate of the refrigerating chamber can be improved.

이상 설명한 바와 같이 본 발명에 따르면, 냉장고의 초기 기동시나 과부하 투입시 냉장실 센서의 구동온/오프점을 재설정하여 온도제어를 수행함으로써 냉장실의 냉각 속도를 향상시키고, 동시에 식품을 신선하게 보관할 수 있게 된다.As described above, according to the present invention, the temperature control is performed by resetting the driving on / off point of the refrigerating compartment sensor during the initial startup of the refrigerator or the overloading, thereby improving the cooling rate of the refrigerating compartment and at the same time keeping the food fresh. .
