Description
본 발명은 냉장고의 운전방법에 관한 것으로서, 특히 냉장고에 설치된 에어커튼팬을 이용하여 냉장고에서 발생하는 약냉을 방지하는 냉장고의 약냉 방지방법에 관한 것이다.The present invention relates to a method of operating a refrigerator, and more particularly, to a method of preventing cold cooling of a refrigerator by using the air curtain fan installed in the refrigerator to prevent weak cooling generated in the refrigerator.
일반적으로 냉장고는 음식물을 일정기간 동안 신선하게 유지시키는 용도로 사용되는 전자제품으로 첨부도면 도 1에 도시된 바와같이 본체(10)와, 본체(10) 내부에 양분되어 음식물을 냉동 보관하는 냉동실(11) 및 냉장 보관하는 냉장실(12)과, 본체(10)의 전면에 설치되어 냉동실(11)을 개폐시켜 주는 냉동실도어(13) 및 냉장실(12)을 개폐시켜 주는 냉장실도어(14)와, 상기 냉동실(11)과 냉장실(12)의 냉각에 필요한 냉기를 만들어 주는 냉동싸이클과, 냉동싸이클에서 만들어진 냉기를 냉동실(11) 및 냉장실(12)로 보내주는 냉기공급수단으로 크게 구성되어 있다.In general, a refrigerator is an electronic product used for keeping food fresh for a certain period of time. As shown in FIG. 1, the refrigerator is divided into a main body 10 and a freezer compartment for freezing and storing food in the main body 10. 11) and a refrigerating chamber 12 for refrigerating, a refrigerating chamber door 13 for opening and closing the freezer compartment 11 and a refrigerating chamber door 14 for opening and closing the freezer compartment 11 at the front of the main body 10, It is composed of a freezing cycle for making the cold air required for cooling the freezing chamber 11 and the refrigerating chamber 12, and a cold air supply means for sending the cold air made in the freezing cycle to the freezing chamber 11 and the refrigerating chamber 12.
상기와 같은 냉장고의 냉동싸이클은 도 2에 나타낸 바와같이 저온, 저압의 기체냉매를 고온, 고압의 기체냉매로 압축하는 압축기(15)와, 상기 고온, 고압의 기체냉매를 응축시켜 고온, 고압의 액체냉매로 변환시켜 주는 응축기(16)와, 상기 고온, 고압의 액체냉매를 저온, 저압의 액체냉매로 변환시켜 주는 모세관(17)과, 상기 저온, 저압의 액체냉매를 저온, 저압의 기체냉매로 증발시켜 주는 증발기(18)와, 상기 각 구성품을 일체화하면서 냉매의 이동통로 역할하는 연결파이프(19)로 구성되어 있다.As shown in FIG. 2, the refrigerating cycle of the refrigerator includes a compressor 15 for compressing a low-temperature, low-pressure gas refrigerant into a high-temperature, high-pressure gas refrigerant, and condensing the high-temperature, high-pressure gas refrigerant to a high-temperature, high-pressure pressure. A condenser 16 for converting a liquid refrigerant, a capillary tube 17 for converting the high temperature and high pressure liquid refrigerant into a low temperature and low pressure liquid refrigerant, and a low temperature and low pressure gas refrigerant for the low temperature and low pressure liquid refrigerant. And an evaporator 18 for evaporating the furnace, and a connecting pipe 19 serving as a moving passage of the refrigerant while integrating the respective components.
따라서, 냉동실(11)에 냉동용 음식물을 채우고 냉장실(12)에는 냉장용 음식물을 채운상태에서 전원을 공급시키면 콘트롤러의 제어신호를 받아 냉동싸이클을 구성하는 압축기(15)가 구동되어 저온, 저압의 기체냉매를 고온, 고압의 기체냉매로 압축시킨다.Therefore, when the refrigeration chamber 11 is filled with the food for freezing and the refrigeration chamber 12 is supplied with the refrigerated food in the state of filling the refrigerated food, the compressor 15 constituting the refrigeration cycle is driven under the control signal of the controller to operate at low temperature and low pressure. The gas refrigerant is compressed into a gas refrigerant of high temperature and high pressure.
이 압축된 고온, 고압의 기체냉매는 연결파이프(19)에 안내되어 응축기(16)를 통과하면서 고온, 고압의 액체냉매로 응축되며 이 응축된 고온, 고압의 액체냉매는 연결파이프(19)에 안내되어 모세관(17)를 통과하면서 온도와 압력이 급격히 떨어진 저온, 저압의 액체냉매로 변환된 다음 계속해서 연결파이프(19)에 안내되어 증발기(18)를 통과하면서 저온, 저압의 기체냉매로 변환되어 증발되는데, 이때 상기 증발기(18)의 증발작용에 의해 주위의 공기가 열교환되므로 냉기가 발생된다.The compressed high-temperature, high-pressure gas refrigerant is guided to the connecting pipe 19 and condensed into a high-temperature, high-pressure liquid refrigerant while passing through the condenser 16. The condensed high-temperature, high-pressure liquid refrigerant is transferred to the connecting pipe 19. Guided through the capillary tube 17, the temperature and pressure is rapidly converted into low-temperature, low-pressure liquid refrigerant and then guided to the connecting pipe 19 to pass through the evaporator 18 to convert to low-temperature, low-pressure gas refrigerant The evaporator 18 is then evaporated. At this time, the ambient air is heat-exchanged by the evaporation of the evaporator 18 so that cold air is generated.
이와같이 증발기(18)에서 발생된 냉기는 냉기공급수단에 의해 일부가 냉동실(11)로 공급되어 상기 냉동실(11)을 냉각시켜 주므로 냉동실(11)에 보관된 음식물이 냉동됨과 함께 일부가 냉장실(12)로 공급되어 상기 냉장실(12)을 냉각시켜 주므로 냉장실(12)에 보관된 음식물이 냉장된다.As such, the cold air generated in the evaporator 18 is partially supplied to the freezing chamber 11 by the cold air supply means to cool the freezing chamber 11, so that the food stored in the freezing chamber 11 is frozen and a portion of the cold chamber 12 is cooled. Since the refrigerator is cooled to the refrigerator compartment 12, the food stored in the refrigerator compartment 12 is refrigerated.
이와 같이 구성된 종래기술에 따른 냉장고는 냉장실 냉각용 냉장실팬의 운전율이 기준이상 길거나, 냉장실온도 감지부의 온도 감지부의 온도 변화율이 기준이상 크면 냉장고에 약냉이 발생하는 문제점이 있다.In the refrigerator according to the prior art configured as described above, if the operation rate of the refrigerating compartment cooling refrigerator fan is longer than the reference or the temperature change rate of the temperature detection unit of the refrigerating compartment temperature detecting unit is larger than the reference, there is a problem that the cooling occurs in the refrigerator.
따라서, 냉장고의 냉장효율이 저하될 뿐만 아니라 식품의 부패 및 변질 등의 원인이 되는 미생물의 증식으로 식품의 선도가 떨어진다.Therefore, not only the refrigerator's refrigeration efficiency is lowered, but also the freshness of the food is reduced due to the growth of microorganisms that cause decay and deterioration of the food.

도 3를 참조하면, 본 발명에 따른 냉장고는 냉장고의 구동에 따른 냉장실의 내부 온도를 감지하는 냉장실온도 감지부(20)와, 냉장실온도 감지부(20)의 제어신호에 따라 냉장고의 전체 시스템을 제어하는 중앙제어부(22)와, 중앙제어부(22)의 제어신호에 따라 냉장실로 냉기를 공급하는 에어커튼팬(24)을 구동하는 에어커튼팬 구동부(26)로 구성된다.3, the refrigerator according to the present invention is a refrigerator system temperature sensing unit 20 for detecting the internal temperature of the refrigerator compartment according to the operation of the refrigerator, and the entire system of the refrigerator according to the control signal of the refrigerator compartment temperature detector 20 A central control unit 22 for controlling and an air curtain fan driving unit 26 for driving the air curtain fan 24 for supplying cold air to the refrigerating chamber in accordance with the control signal of the central control unit 22.
이와 같이 구성된 냉장고의 약냉 방지방법을 도 4를 참조하여 설명하면 다음과 같다.A method of preventing cold cooling of the refrigerator configured as described above will be described with reference to FIG. 4.
먼저, 냉장고의 전원플러그를 전원콘센트에 연결하게 되면, 냉장고는 통상운전을 한다(S101).First, when the power plug of the refrigerator is connected to the power outlet, the refrigerator performs normal operation (S101).
이때, 상기 냉장고가 통상운전을 하는 동안 냉장고의 냉장실온도 감지부(20)는 냉장실의 주위온도를 감지하여 중앙제어부(22)에 보낸다.At this time, the refrigerator compartment temperature detector 20 of the refrigerator detects the ambient temperature of the refrigerator compartment and sends it to the central controller 22 during the normal operation of the refrigerator.
상기 중앙제어부(22)는 냉장실온도 감지부(20)에 감지된 온도에 따라 냉장실팬(미도시)을 구동시키고 상기 구동되는 냉장실팬의 운전율을 계산한다(S102).The central controller 22 drives a refrigerator compartment fan (not shown) according to the temperature sensed by the refrigerator compartment temperature detector 20 and calculates an operation rate of the driven refrigerator compartment fan (S102).
이어, 상기 냉장실팬의 운전율과 중앙제어부(22)에 미리 설정된 냉장실팬 운전율을 비교하여(S103) 냉장실팬의 운전율이 중앙제어부(22)에 설정된 냉장실팬 운전율 보다 크면 냉장실에 약냉이 발생됨으로 상기 중앙제어부(22)가 에어커튼팬구동부(26)에 제어신호를 주어 에어커튼팬(24)을 일정시간 구동시킨다(S104).Subsequently, the operation rate of the refrigerator compartment fan is compared with the operation rate of the refrigerator compartment fan set in advance in the central control unit 22 (S103). If the operation rate of the refrigerator compartment fan is greater than the operation rate of the refrigerator compartment fan in the central control unit 22, the weak cooling is performed in the refrigerator compartment. The central control unit 22 generates a control signal to the air curtain fan driver 26 to drive the air curtain fan 24 for a predetermined time (S104).
상기 에어커튼팬(24)의 구동이 일정시간 경과 했는지를 판단하여(S105) 에어커튼팬(24)의 구동이 일정시간 경과 했으면 에어커튼팬(24)의 구동을 오프한다(S106).It is determined whether the driving of the air curtain fan 24 has elapsed for a predetermined time (S105). If the driving of the air curtain fan 24 has elapsed for a predetermined time, the driving of the air curtain fan 24 is turned off (S106).
만약, 냉장실팬의 운전율이 중앙제어부(22)에 설정된 냉장실팬 운전율 보다 작으면 냉장실온도 감지부(20)에 감지된 온도와 중앙제어부(22)에 미리 설정된 냉장실온도를 비교하여(S107) 냉장실온도 감지부(20)에 감지된 온도가 중앙제어부(22)에 미리 설정된 냉장실온도 보다 크면 냉장실에 약냉이 발생됨으로 상기 중앙제어부(22)가 에어커튼팬구동부(26)에 제어신호를 주어 에어커튼팬(24)을 일정시간 구동시킨다(S108).If the operation rate of the refrigerator compartment fan is smaller than the operation rate of the refrigerator compartment fan set in the central controller 22, the temperature detected by the refrigerator compartment temperature detector 20 is compared with the refrigerator compartment temperature preset in the central controller 22 (S107). When the temperature sensed by the refrigerating compartment temperature detecting unit 20 is greater than the refrigerating compartment temperature set in advance by the central control unit 22, the cooling compartment is generated in the refrigerating compartment, so that the central control unit 22 gives a control signal to the air curtain fan driver 26 to provide air. The curtain fan 24 is driven for a predetermined time (S108).
상기 에어커튼팬(24)의 구동이 일정시간 경과 했는지를 판단하여(S109) 에어커튼팬(24)의 구동이 일정시간 경과 했으면 에어커튼팬(24)의 구동을 오프한다(S110).It is determined whether the driving of the air curtain fan 24 has elapsed for a predetermined time (S109). If the driving of the air curtain fan 24 has elapsed for a predetermined time, the driving of the air curtain fan 24 is turned off (S110).
본 발명에 따른 냉장고의 약냉 방지방법은 냉장실 냉각용 냉장실팬의 운전율이 기준이상 길거나, 냉장실온도 감지부의 온도 감지부의 온도 변화율이 기준이상 클 경우 냉장고에서 발생되는 약냉을 사전에 방지하는 효과가 있다.The method for preventing the weak cooling of the refrigerator according to the present invention has an effect of preventing the weak cooling generated in the refrigerator in advance when the operation rate of the refrigerating compartment fan for the refrigerating compartment is longer than the reference, or the temperature change rate of the temperature detection unit of the refrigerating compartment temperature detection unit is larger than the reference. .
