Description
본 발명은 냉장고의 제어방법에 관한 것으로서, 특히 사용자가 냉장고의 도어를 열었을 경우의 냉장고의 냉동실팬 제어방법에 관한 것이다.The present invention relates to a method of controlling a refrigerator, and more particularly, to a method of controlling a freezer compartment fan of a refrigerator when a user opens a door of the refrigerator.
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.
상기 냉장고의 냉동싸이클을 살펴보면, 일반적으로 압축기(미도시)에서 토출된 고온고압의 냉매가스가 응축기(미도시)를 통과하면서 외부로 열이 방출되어 고압의 액상냉매가 된후, 드라이어(미도시)를 통과하면서 고압의 액상냉매는 불순물과 수분 등이 제거되어 캐필러리튜브(미도시)를 거치게 되며, 캐필러리튜브를 통과하면서 액상냉매는 증발하기 쉬운 기액 혼합 상태로 팽창되어 증발기(미도시)를 통해 주변의 열을 흡수하여 가스화되는 순환반복에 의해 냉장고에 냉기공급이 이루어진다.Looking at the refrigeration cycle of the refrigerator, in general, the high-temperature high-pressure refrigerant gas discharged from the compressor (not shown) passes through the condenser (not shown) to release heat to the outside to become a high-pressure liquid refrigerant, the dryer (not shown) The high pressure liquid refrigerant passes through the capillary tube (not shown) by removing impurities and moisture while passing through the capillary tube, and the liquid refrigerant expands to a gas-liquid mixed state that is easily evaporated while passing through the capillary tube. Cold air is supplied to the refrigerator by repeating the circulation of gas by absorbing the surrounding heat through the gas.
최근에는 냉장고의 운전시 냉장실내에 과부하가 투입되거나, 냉장실의 도어가 열려 외기가 유입되어 냉장실의 온도가 상승하는 경우, 압축기와 냉장실팬만을 사용하는 종래의 운전방법 보다 냉장실의 전체온도를 정상적인 온도로 신속하게 회복시켜주기 위하여 에어커튼팬을 냉장실에 추가로 설치하여 사용하고 있다.Recently, when the operation of the refrigerator is overloaded, or when the temperature of the refrigerating chamber increases due to the inflow of outside air by opening the door of the refrigerating chamber, the overall temperature of the refrigerating chamber is kept at a normal temperature than the conventional operation method using only the compressor and the refrigerating chamber fan. In order to recover quickly, an additional air curtain fan is installed in the refrigerating chamber.
이와같이 구성된 종래의 냉장고는 사용자가 냉장고의 도어를 열 때 냉동실이 바로 정지되는 문제점이 있다.The conventional refrigerator configured as described above has a problem in that the freezing compartment is immediately stopped when the user opens the door of the refrigerator.
따라서, 냉장고의 외부 따뜻한 공기가 냉동 및 냉장실로 유입되어 냉동 및 냉장실에 저장된 음식물의 변질이 발생하는 문제점이 있다.Therefore, the external warm air of the refrigerator flows into the freezing and refrigerating compartment, and thus there is a problem in that deterioration of food stored in the freezing and refrigerating compartment occurs.

도 2는 본 발명에 따른 냉장고의 구성블록도이고, 도 3은 본 발명에 따른 냉장고의 냉동실팬 제어방법을 나타낸 흐름도이다.2 is a block diagram of a refrigerator according to the present invention, Figure 3 is a flow chart showing a method for controlling a freezer compartment fan of the refrigerator according to the present invention.
도 2를 참조하면, 본 발명에 따른 냉장고는 냉장고의 구동시에 냉장고의 냉동실 온도를 감지하는 냉동실온도 감지센서(20)와, 상기 냉장고의 냉동실온도 감지센서(20)에 감지된 제어신호에 따라 냉장고의 전체 시스템을 제어하는 중앙제어부(22)와, 상기 냉장고의 도어의 개폐여부를 감지하는 도어개폐 감지부(24)와, 상기 냉동실온도 감지센서에 감지된 온도에 따라 냉동실팬(26)을 구동시키는 냉동실팬구동부(28)로 구성된다.Referring to FIG. 2, the refrigerator according to the present invention includes a freezer compartment temperature sensor 20 that detects a freezer compartment temperature of the refrigerator when the refrigerator is driven, and a control signal detected by the freezer compartment temperature sensor 20 of the refrigerator. The central control unit 22 to control the entire system of the door, the door opening and closing detection unit 24 for detecting the opening or closing of the door of the refrigerator, and driving the freezer compartment 26 according to the temperature detected by the freezer temperature sensor It consists of a freezer compartment fan drive unit 28.
이와 같이 구성된 본 발명에 따른 냉장고의 냉동실팬의 동작을 도 3를 참조하여 설명하면 다음과 같다.The operation of the freezer compartment fan of the refrigerator according to the present invention configured as described above will be described with reference to FIG. 3.
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, 냉장고의 중앙제어부가 모터구동부를 통해서 압축기 및 냉동실팬을 각각 구동시켜 냉각운전한다.At this time, the central control unit of the refrigerator drives the compressor and the freezer compartment fan through the motor driving unit, respectively, to perform a cooling operation.
이어, 상기 냉장고가 통상운전을 하는 동안 냉장실의 도어가 열렸는지를 판단하여(S102) 냉장실의 도어가 열려 있으면 냉장고의 냉동실팬이 동작되고 있는지를 판단한다(S103).Subsequently, it is determined whether the door of the refrigerating compartment is opened during the normal operation of the refrigerator (S102). If the door of the refrigerating compartment is opened, it is determined whether the freezer compartment fan of the refrigerator is operating (S103).
만약, 상기 냉장고의 냉동실팬이 동작되고 있으면 냉동실팬의 동작시간이 냉동실팬 동작 설정시간을 경과 했는지를 판단하여(S104) 냉동실팬의 동작시간이 냉동실팬 동작 설정시간을 경과 했으면 냉동실팬의 동작을 정지시킨다(S105).If the freezer compartment of the refrigerator is operating, it is determined whether the operation time of the freezer compartment has passed the freezer compartment operation setting time (S104), and if the operation time of the freezer compartment fan has passed the freezer compartment operation setting time, the operation of the freezer compartment fan is performed. It stops (S105).
상기 설정시간은 1분정도 이다.The setting time is about 1 minute.
상기 냉동실팬의 동작시간이 냉동실팬 동작 설정시간을 경과 하지 않았으면 냉동실온도 감지센서에 감지된 온도와 사용자가 초기에 설정한 냉동실온도를 비교하여(S106) 냉동실온도 감지센서에 감지된 온도가 사용자가 초기에 설정한 냉동실온도 보다 크면 냉동실팬의 동작을 정지시킨다.If the operation time of the freezer compartment fan does not pass the freezer compartment operation setting time, the temperature detected by the freezer compartment temperature sensor is compared with the freezer compartment temperature initially set by the user (S106). Is greater than the initially set freezer temperature, the freezer fan is stopped.
만약, 상기 냉동실온도 감지센서에 감지된 온도가 사용자가 초기에 설정한 냉동실온도 보다 작으면 냉장고 도어가 닫혔는가를 판단하여(S107) 냉장고 도어가 닫혀 있으면 냉동실팬의 동작을 정지시킨다.If the temperature detected by the freezer compartment temperature sensor is less than the freezer compartment temperature initially set by the user, it is determined whether the refrigerator door is closed (S107). If the refrigerator door is closed, the operation of the freezer compartment fan is stopped.
그리고 상기 냉장고 도어가 닫혀 있지 않으면 냉동실팬이 동작되고 있는지를 확인한다.If the refrigerator door is not closed, check whether the freezer compartment fan is operating.
본 발명에 따른 냉장고의 냉동실팬 제어방법은 사용자가 냉장고의 도어를 열었을 경우에 냉동실팬이 바로 정지되지 않고 소정시간 동작됨으로써 냉장고의 냉동 및 냉장실에 저장된 음식물의 변질을 방지할 수 있는 효과가 있다.The method of controlling the freezer compartment fan of the refrigerator according to the present invention has an effect of preventing the deterioration of food stored in the freezer and the refrigerating compartment of the refrigerator by operating the predetermined time without stopping the freezer fan immediately when the user opens the door of the refrigerator.
