Description

냉장고의 냉장실 운전 제어방법How to control the operation of the refrigerator

본 발명은 냉장고의 제어방법에 관한 것으로서, 특히 냉장고의 외기온도 감지센서 및 냉장실의 냉장실온도 감지센서가 동시에 고장이 났을 경우의 냉장고의 냉장실 운전 제어방법에 관한 것이다.The present invention relates to a method for controlling a refrigerator, and more particularly, to a method for controlling a refrigerator operation of a refrigerator when an external temperature sensor of a refrigerator and a refrigerator temperature sensor of a refrigerator compartment fail at the same time.

일반적으로 냉장고는 음식물을 일정기간 동안 신선하게 유지시켜는 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 predetermined 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 the refrigerating compartment 12 for refrigerating, the freezer compartment 13 installed at the front of the main body 10 to open and close the freezer compartment 11, and the refrigerating compartment door 14 for opening and closing the refrigerating compartment 12; It is largely composed of a freezing cycle for making cold air required for cooling the freezing chamber 11 and the refrigerating chamber 12, and 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.

도 3를 참조하면, 일반적인 냉장고는 냉장고의 구동에 따른 냉동/냉장실의 내부 온도를 감지하는 냉동/냉장실온도 감지센서(20)(22)와, 냉장고의 외부에 설치되고 냉장고의 외기온도를 감지하는 외기온도 감지센서(24)와, 냉동/냉장실온도 감지센서(20)(22) 및 외기온도 감지센서(24)의 제어신호에 따라 냉장고의 전체 시스템을 제어하는 중앙제어부(26)와, 중앙제어부(26)의 제어신호에 따라 압축기(30) 및 냉동/냉장실팬(32)을 구동하는 모터구동부(28)로 구성된다.Referring to FIG. 3, a typical refrigerator includes a refrigerator / freezer temperature sensor 20 and 22 for detecting an internal temperature of a refrigerator / freezer according to driving of the refrigerator, and installed outside the refrigerator to detect an outside temperature of the refrigerator. Central control unit 26 for controlling the entire system of the refrigerator in accordance with the control signal of the outside air temperature sensor 24, the freezer / refrigerator temperature sensor 20, 22 and the outside air temperature sensor 24, and the central control unit And a motor driver 28 for driving the compressor 30 and the freezer / refrigeration chamber fan 32 in accordance with the control signal of (26).

이와같이 구성된 종래의 냉장고는 냉장고의 외기온도 감지센서 및 냉장실의 냉장실온도 감지센서가 동시에 고장이 났을 경우에 냉장실팬을 중앙제어부가 제대로 제어할 수 없어 냉장실의 온도가 급상승하거나, 급하강하는 문제점이 있다.The conventional refrigerator configured as described above has a problem in that the temperature of the refrigerator compartment rises or falls rapidly because the central control unit cannot properly control the refrigerator compartment fan when the outside temperature sensor of the refrigerator and the refrigerator compartment temperature sensor of the refrigerator compartment fail at the same time. .

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.

본 발명은 상기한 종래기술의 제반 문제점을 해결하기 위하여 안출한 것으로서, 본 발명의 목적은 냉장고의 외기온도 감지센서 및 냉장실의 냉장실온도 감지센서가 동시에 고장이 났을 경우에 냉장실팬을 소정 시간마다 구동시켜 냉장실의 온도를 제어하는 냉장실 운전 제어방법을 제공함에 있다.The present invention has been made to solve the above-mentioned problems of the prior art, an object of the present invention is to drive the refrigerator compartment fan every predetermined time when the outside temperature sensor of the refrigerator and the refrigerator compartment temperature sensor of the refrigerator compartment at the same time failure. It is to provide a refrigerating chamber operation control method for controlling the temperature of the refrigerating chamber.

Indicated that the refrigerator compartment temperature sensor is broken in the installed display unit, and if the outside temperature sensor of the refrigerator is normal, the central control unit of the refrigerator determines whether the sensor has malfunctioned. According to the step of driving the refrigerator compartment fan, and when the outside temperature sensor of the refrigerator detecting the outside temperature of the refrigerator has failed, the outside temperature sensor of the refrigerator has failed in the display unit installed at the outside of the refrigerator. Display step and the outside temperature sensor of the refrigerator for detecting the outside temperature of the refrigerator If the fridge temperature sensor of the fridge fails simultaneously, the central control unit operates the fridge fan every predetermined time to control the temperature of the fridge, including the external air temperature sensor of the refrigerator and the fridge temperature sensor of the fridge. In this case, by operating the refrigerator compartment fan every predetermined time to control the temperature of the refrigerator compartment to prevent the deterioration of food contained in the refrigerator compartment of the refrigerator.

이하, 본 발명에 따른 냉장실 운전 제어방법의 바람직한 일 실시예를 첨부한 도면을 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings a preferred embodiment of the refrigerating chamber operation control method according to the present invention.

도 4는 본 발명에 따른 냉장고의 냉장실 운전 제어방법을 나타낸 흐름도이다.4 is a flowchart illustrating a method for controlling a refrigerator compartment operation of a refrigerator according to the present invention.

도 4를 참조하면, 본 발명에 따른 냉장실 운전 제어방법은 먼저, 냉장고의 전원플러그를 전원콘센트에 연결하게 되면, 냉장고는 통상운전을 한다(S101).Referring to FIG. 4, in the refrigerating compartment operation control method according to the present invention, first, when the power plug of the refrigerator is connected to a power outlet, the refrigerator performs normal operation (S101).

이때, 사용자가 냉장실의 온도조절 버튼(절전, 약, 중, 강)(미도시)을 누르면 냉장실온도 감지센서(22)가 냉장실 내부의 온도를 감지한다.At this time, when the user presses the temperature control button (sleep, weak, medium, strong) (not shown) of the refrigerator compartment, the refrigerator compartment temperature sensor 22 detects a temperature inside the refrigerator compartment.

이어, 냉장실온도 감지센서(22)에 감지된 냉장실 내부 온도에 따라 냉장실팬(32)이 구동된다.Subsequently, the refrigerating compartment fan 32 is driven according to the refrigerating compartment internal temperature sensed by the refrigerating compartment temperature sensor 22.

만약, 상기 냉장실 내부의 온도를 감지하는 냉장실온도 감지센서(22)가 고장이 났을 경우에(S102) 중앙제어부(26)는 이를 감지하고 냉장고의 외측에 설치된 표시부(미도시)에 냉장실온도 감지센서(22)가 고장이 났다는 것을 표시한다(S103).If, when the refrigerator compartment temperature sensor 22 for detecting the temperature inside the refrigerator compartment is broken (S102), the central control unit 26 detects this and the refrigerator compartment temperature sensor on the display unit (not shown) installed outside the refrigerator. (22) indicates that a failure has occurred (S103).

이어, 상기 중앙제어부(26)는 냉장고의 외기온도 감지센서(24)가 고장이 발생했는가를 판단하여(S104) 냉장고의 외기온도 감지센서(24)가 정상적인 경우에는 냉장고의 외기 온도에 따라(S105)(S106)(S107) 중앙제어부(26)는 냉장실팬(32)을 아래표 1과 같이 운전시킨다(S108)(S109)(S110).Subsequently, the central controller 26 determines whether a failure of the outside air temperature sensor 24 of the refrigerator occurs (S104), and when the outside air temperature sensor 24 of the refrigerator is normal, according to the outside air temperature of the refrigerator (S105). (S106) (S107) The central control unit 26 drives the refrigerator compartment fan 32 as shown in Table 1 below (S108) (S109) (S110).

냉장고의 외기온도(RT)Refrigerator outside temperature (RT) 냉장실팬의 온/오프시간(주기20분)Refrigerator fan on / off time (20 minutes cycle) RT＜14℃RT <14 ℃ 7분/13분7 minutes / 13 minutes 14℃＜RT＜26℃14 ℃ <RT <26 ℃ 8분/12분8 minutes / 12 minutes RT＞26℃RT ＞ 26 ℃ 9분/11분9 minutes / 11 minutes

만약, 상기 냉장고의 외부 온도를 감지하는 냉장고의 외기온도 감지센서(24)가 고장이 났을 경우에 중앙제어부(26)는 이를 감지하고 냉장고의 외측에 설치된 표시부(미도시)에 냉장고의 외기온도 감지센서(24)가 고장이 났다는 것을 표시한다(S111).If the outside temperature sensor 24 of the refrigerator detecting the outside temperature of the refrigerator has failed, the central controller 26 detects this and detects the outside temperature of the refrigerator on a display unit (not shown) installed outside the refrigerator. It indicates that the sensor 24 has failed (S111).

따라서, 냉장고의 외기온도 감지센서(24) 및 냉장실의 냉장실온도 감지센서(22)가 동시에 고장이 났을 경우에 냉장실팬을 소정 시간마다 구동시켜 냉장실의 온도를 제어한다(S111).Therefore, when the outside temperature sensor 24 of the refrigerator and the refrigerator temperature sensor 22 of the refrigerator compartment fail at the same time, the refrigerator compartment fan is driven every predetermined time to control the temperature of the refrigerator compartment (S111).

즉, 상기 냉장실팬를 20분 주기로 8분은 냉장실팬을 구동시키고, 12분은 냉장실팬을 오프시킨다.That is, the refrigerator compartment fan is driven at a refrigerating fan for 20 minutes and the refrigerator compartment fan is turned off for 12 minutes.

본 발명에 따른 냉장고의 냉장실 운전 제어방법은 냉장고의 외기온도 감지센서 및 냉장실의 냉장실온도 감지센서가 동시에 고장이 났을 경우에 냉장실팬을 소정 시간마다 구동시켜 냉장실의 온도를 제어함으로써 냉장고의 냉장실 내부에 들어 있는 음식물의 변질을 방지할 수 있는 효과가 있다.Refrigeration room operation control method of the refrigerator according to the present invention controls the temperature of the refrigerator compartment by driving the refrigerator compartment fan every predetermined time when the outside temperature sensor and the refrigerator compartment temperature sensor of the refrigerator breaks down at the same time to the inside of the refrigerator compartment There is an effect that can prevent the deterioration of the food contained.
