Explain.
설정온도조절부(10)는 사용자로부터 입력받은 외부설정온도값, 냉동실설정온도값 및 냉장실설정온도값을 제어부(30)측으로 출력한다.The set temperature controller 10 outputs an external set temperature value, a freezer compartment set temperature value, and a refrigerator compartment set temperature value received from the user to the controller 30.
외부온도감지부(200)는 외부 온도를 감지하는 외부 온도 감지 센서로부터 외부온도감지값을 입력받아 상기 제어부(30)에 이 값을 출력한다.The external temperature sensing unit 200 receives an external temperature sensing value from an external temperature sensing sensor that senses an external temperature and outputs this value to the controller 30.
상기 제어부(30)는 상기 외부온도감지값과 외부 환경이 저온 상태인지를 판단하는 기준이 되는 상기 외부설정온도값을 비교한다.The controller 30 compares the external temperature detection value with the external preset temperature value, which is a reference for determining whether the external environment is in a low temperature state.
만약 외부온도감지값이 외부설정온도값보다 작다고 판단하면 상기 제어부(30)는 냉동실온도감지부(100)를 통해 냉동실의 온도를 감지한다. 이 온도값이 냉동실감지온도값이다.If it is determined that the external temperature detection value is smaller than the external set temperature value, the controller 30 senses the temperature of the freezer compartment through the freezer compartment temperature detection unit 100. This temperature value is a freezer compartment sensing temperature value.
만약 냉동실감지온도값이 냉동실설정온도값보다 크다고 판단하면 상기 제어부(30)는 냉동실감지온도값이 냉동실설정온도값보다 작을 때까지 콤프래셔(41)와 냉동실 팬모터(42)를 구비한 부하구동부(40)를 동작시킨다.If it is determined that the freezer detection temperature value is greater than the freezer setting temperature value, the control unit 30 includes a load driving unit including the compressor 41 and the freezer fan motor 42 until the freezer detection temperature value is smaller than the freezer setting temperature value. Operate 40.
이후, 상기 제어부(30)는 냉동실감지온도값이 냉동실설정온도값보다 작다고 판단하면 콤프래셔(41)와 냉동실 팬모터(42)를 구비한 상기 부하구동부(40)의 동작을 중지시킨다.Thereafter, when the control unit 30 determines that the freezer compartment sensing temperature value is smaller than the freezer compartment set temperature value, the control unit 30 stops the operation of the load driving unit 40 including the compressor 41 and the freezer compartment fan motor 42.
또 다른 경우로, 만약 외부온도감지값이 외부설정온도값보다 크다고 판단하면 상기 제어부(30)는 냉장실온도감지부(100)를 통해 냉장실의 온도를 감지한다. 이 온도값이 냉장실감지온도값이다.In another case, if it is determined that the external temperature detection value is greater than the external set temperature value, the control unit 30 detects the temperature of the refrigerating compartment through the refrigerating compartment temperature detecting unit 100. This temperature value is a refrigerator compartment sensing temperature value.
만약 냉장실감지온도값이 냉장실설정온도값보다 크다고 판단하면 상기 제어부(30)는 냉장실감지온도값이 냉장실설정온도값보다 작을 때까지 콤프래셔(41)와 냉동실 팬모터(42)를 구비한 부하구동부(40)를 동작시킨다.If it is determined that the refrigerating chamber sensing temperature value is greater than the refrigerating chamber set temperature value, the control unit 30 includes a load driving unit including the compressor 41 and the freezer compartment fan motor 42 until the refrigerating chamber sensing temperature value is smaller than the refrigerating chamber set temperature value. Operate 40.
이후, 상기 제어부(30)는 냉장실감지온도값이 냉장실설정온도값보다 작다고 판단하면 콤프래셔(41)와 냉동실 팬모터(42)를 구비한 상기 부하구동부(40)의 동작을 중지시킨다.Thereafter, the controller 30 stops the operation of the load driver 40 including the compressor 41 and the freezer compartment fan motor when it determines that the refrigerator compartment sensing temperature value is smaller than the refrigerator compartment set temperature value.
그러나, 상기와 같은 종래 기술에 있어서, 외부 온도에 관계없이 제어부는 냉장실의 온도를 감지하여 그 온도값이 설정온도값 이하이면 콤프래셔와 구동부의 운전을 중지하므로 냉동실의 온도를 만족시키지 못하여 냉동실의 음식물이 녹는 문제점이 있다.However, in the prior art as described above, regardless of the external temperature, the control unit detects the temperature of the refrigerating chamber and stops the operation of the compressor and the driving unit when the temperature value is lower than the set temperature, so that the temperature of the freezer compartment is not satisfied. There is a problem that the food melts.
따라서, 본 발명은 상기와 같은 문제점을 감안하여 창안한 것으로, 외부 온도를 감지하여 콤프래셔와 냉동실팬모터를 구비한 부하구동부를 제어함으로써 냉동실의 고내 온도를 만족시켜 음식물이 신선하게 유지되도록 하는 냉장고 고내 온도 제어 방법을 제공함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above problems, by controlling the load drive unit having a compressor and a freezer fan motor by sensing an external temperature to satisfy the internal temperature of the freezer compartment to keep food fresh. The purpose is to provide a temperature control method within the refrigerator.
