이와같은 목적을 달성하기 위한 본 발명은 냉장실용 전용 냉각팬을 구비하고, 제상주기가 검츨되었는가를 판단하는 단계와, 제상시작 시점이 검출되면 제상용히터를 구동시키는 단계와, 냉각기의 온도가 제상완료온도로 검출되면 제상용히티의 구동을 중지시키는 단계를 포함하는 냉장고의 제상방법에 있어서, 상기 제상시기가 검출되면 제상용히터의 구동과 동시에 냉장실용 냉각팬을 구동시켜 냉동실로 유입되는 온기를 차단하는 단계와, 제상이 완료되면 제상용히터의 중지와 동시에 냉장실용 냉각팬의 구동을 정상모드로 구동시키는 단계를 포함하여 된 특징이 있다.In order to achieve the above object, the present invention includes a dedicated cooling fan for a refrigerating compartment, determining whether a defrost cycle has been detected, driving a defrost heater when a start point of defrost is detected, and defrosting the temperature of the cooler. In the defrosting method of the refrigerator comprising the step of stopping the drive of the defrosting hitty when detected as the completion temperature, when the defrosting time is detected, the warm air flowing into the freezer compartment by driving the cooling fan for the refrigerating compartment simultaneously with the operation of the defrosting heater It is characterized in that it comprises the step of blocking, and when the defrosting is completed, driving the cooling fan for the refrigerating compartment in the normal mode at the same time as the defrosting heater is stopped.
이하, 첨부된 도면에 의거하여 본 발명을 보다 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 발명이 적용되는 냉장고의 제어 블럭도로서, 냉각기(evaporator)의 온도를 검출하는 냉각기 온도검출부(10)와, 냉장실의 온도를 하는 검출하는 냉장실 온도검출부(20)와, 본 발명에 의한 일정 프로그램을 내장하여 기기의 전체동작을 제어하는 제어부(30)와, 제상용히터 및 냉장실용 냉각팬을 구동시키는 히터 팬및 구동부(40)로 구성된 것에 본 발명은 적용된다.1 is a control block diagram of a refrigerator to which the present invention is applied, which includes a cooler temperature detection unit 10 for detecting a temperature of an evaporator, a refrigerating chamber temperature detection unit 20 for detecting a temperature of a refrigerating chamber, and the present invention. The present invention is applied to a control unit 30 that incorporates a schedule program to control the overall operation of the apparatus, a heater fan and a drive unit 40 for driving a defrost heater and a cooling fan for a refrigerating chamber.
제2도는 제1도의 상세 회로도로서, 상기 냉각기 온도검출부(10)는 온도감지소자(TH1), 저항(R1)(R2)으로 구성되어 냉각기에 취부된 온도감지소자(TH1)가 냉각기의 온도를 감지함에 따라 고유저항값이 변하고 그에 따라 저항(R1)과의 전압분배에 따라 제어부(30)의 포트(P1)에 입력되는 전압이 가변되고, 이로 인해 제어부(30)는 냉각기의 온도를 인식하며, 특히 제상완료온도(예: 13℃)를 검출하게 된다.2 is a detailed circuit diagram of FIG. 1, wherein the cooler temperature detector 10 includes a temperature sensing element TH1 and a resistor R1 and R2 so that the temperature sensing element TH1 attached to the cooler adjusts the temperature of the cooler. Upon detection, the value of the resistivity changes and accordingly the voltage input to the port P1 of the controller 30 varies according to the voltage distribution with the resistor R1. As a result, the controller 30 recognizes the temperature of the cooler. In particular, the defrosting completion temperature (eg 13 ° C.) is detected.
또한, 상기 냉장실 온도검출부(20)는 온도감지소자(TH2), 저항(R3)(R4)으로 구성되어 냉장실의 소정부위에 취부된 온도감지소자(TH2)가 냉장실의 온도를 감지함에 따라 고유저항값이 변하고 그에 따라 저항(R3)과의 전압분배에 따라 제어부(30)의 포트(P2)에 입력되는 전압이 가변되고, 이로 인해 제어부(30)는 냉장실의 온도를 인식하며, 냉장실의 온도에 따라 설정한 온도를 기준으로 냉장실용 냉각팬을 온, 오프 구동하게 된다.In addition, the refrigerating compartment temperature detection unit 20 is composed of a temperature sensing element (TH2), the resistance (R3) (R4), the specific resistance as the temperature sensing element (TH2) attached to a predetermined portion of the refrigerating compartment detects the temperature of the refrigerating compartment. The value is changed and accordingly the voltage input to the port P2 of the controller 30 is varied according to the voltage distribution with the resistor R3, whereby the controller 30 recognizes the temperature of the refrigerator compartment, The cooling fan for the refrigerating compartment is turned on and off based on the temperature set accordingly.
또한, 히터 및 팬 구동부(40)는 버퍼(I1),(I2), 다이오드(D1), 릴레이(RY), 제상용히터(HTR), 저항(R5), 포토다이액(PT) 및 냉장실용 팬모터(FM)를 구비하여, 상기 제어부(30)가 제상용히터(HTR)를 구동하기 위하여 포트(P3)로 로우신호를 출력하면 출력된 신호는 버퍼(I1)를 통해 릴레이(RY)를 통전시켜 히터(HTR)는 구동되고 제상작업을 수행하게 된다.In addition, the heater and fan drive unit 40 is used for buffers I1, I2, diodes D1, relays RY, defrost heaters HTR, resistors R5, photodioxides, and refrigerating chambers. With a fan motor FM, when the controller 30 outputs a low signal to the port P3 to drive the defrost heater HTR, the output signal is supplied to the relay RY through the buffer I1. By energizing, the heater HTR is driven to perform defrosting.
또한, 제어부(30)가 냉장실용 냉각팬(FM)을 구동시키기 위하여 포트(P4)로 로우신호를 출력하면, 출력된 신호는 포토다이액(PT)의 발광소자에 인가되어 포토다이액(PT)이 턴온되고, 이 포토다이액(PT)의 턴온으로 냉장실용 팬모터(FM)에 전원(AC)이 인가되어 팬은 구동된다.In addition, when the controller 30 outputs a low signal to the port P4 in order to drive the refrigerating chamber cooling fan FM, the output signal is applied to the light emitting element of the photo die liquid PT and the photo die liquid PT. ) Is turned on, and the power source AC is applied to the refrigerating chamber fan motor FM by turning on the photo die liquid PT, and the fan is driven.
제3도는 본 발명에 의한 제어 흐름도를 나타낸 것으로, 이를 참조하여 본 발명의 작용 및 그에 따른 효과를 설명한다.Figure 3 shows a control flow chart according to the present invention, with reference to this it will be described the operation and effects of the present invention.
먼저, 본 발명이 적용되는 냉장고에 전원을 인가하면, 제어부(30)는 통상의 냉장고제어를 실행함과 동시에 미도시된 압축기(COMPRESSOR)의 구동시간을 체크함으로써 냉각기의 제상주기를 검출한다(S1단계).First, when power is applied to the refrigerator to which the present invention is applied, the control unit 30 detects the defrost cycle of the cooler by executing the normal refrigerator control and checking the driving time of the compressor (not shown) (S1). step).
S1단계에서 검출되면, 제상시작시점인가를 판단한다(S2단계).If detected in step S1, it is determined whether the start of defrosting (step S2).
여기서, 제상시점이 검출되지 아니하면, 포트(P3)로 하이신호가 출력되어 HTR)를 오프상태로 유지한다(S3단계). 그리고, 냉장실용 팬모터(FM)는 사용자가 설정한 냉장실의 온도에 부합하도록 냉장실 온도검출부(20)를 통해 검출되는 냉장실온도에 맞추어 온,오프제어하는 정상모드의 운전제어를 행한다(S4단계).Here, if the defrosting time is not detected, a high signal is output to the port P3 to keep the HTR off (step S3). Then, the refrigerating chamber fan motor FM performs the operation control in the normal mode of controlling the on and off in accordance with the refrigerating chamber temperature detected by the refrigerating chamber temperature detector 20 so as to match the temperature of the refrigerating chamber set by the user (step S4). .
그러나, 상기 S2단계에서 제상시점이 검출되면 포트(P3)로 로우신호를 출력하는 제상용히터(HTR)를 구동시켜준디(S5단계). 그리고, 출력포트(P4)로 로우신호를 출력하여 냉장실용 냉각팬모터(FM)를 구동시켜준다(S6단계).However, when the defrost point is detected in step S2, the defrost heater HTR for outputting a low signal to the port P3 is driven (step S5). Then, the low signal is output to the output port P4 to drive the cooling fan motor FM for the refrigerating chamber (step S6).
따라서, 제상용히터(HTR)의 발열을 발생되는온기는 냉장실용 냉각팬에 의해 냉동실로 투입되지 않고, 냉장실로 투입된다. 따라서, 냉동실로 유입될 수 있는 온기는 차단되는 것이다. 또한, 냉장실로 유입되는 온기는 실험에 의한 결과, 약 1℃정도 냉장실의 고내온도를 상승시키는 것에 불과하고, 제상직후 다시 원래의 고내온도를 회복할 수 있어 큰 문제가 되지 않는다.Therefore, the warmer which generates heat of the defrost heater HTR is not introduced into the freezing compartment by the cooling fan for the refrigerating compartment, but is introduced into the refrigerating compartment. Therefore, the warmth that can be introduced into the freezer compartment is blocked. In addition, the warmth introduced into the refrigerating chamber is a result of experiments, it is only to increase the internal temperature of the refrigerating chamber by about 1 ℃, and can recover the original internal temperature again immediately after defrosting is not a big problem.
그리고, 냉각기 온도검출부(10)를 통해 냉각기의 온도를 검출하여 냉각기의 온도가 13℃이상이 검출되어 제상완료온도인가를 판단한다(S7단계).Then, the temperature of the cooler is detected through the cooler temperature detector 10, and the cooler temperature is detected to be 13 ° C. or higher (step S7).
여기서, 제상완료온도가 검출되면, 제상용히터(HTR)의 구동을 차단시키고 (S8단계), 냉동실용 냉각팬을 정상모드의 제어로 복귀시킨다(S9단계).Here, when the defrosting completion temperature is detected, the drive of the defrost heater (HTR) is cut off (step S8) and the freezing chamber cooling fan is returned to the normal mode control (step S9).
이상에서와 같이 본 발명은 제상시 히터의 열을 냉동실로 보내지 않음으로써 냉동실의 선반이나 식품에 성에가 착상되는 것을 방지하고, 또 식품이 변질되는 것을 방지 할 뿐만 아니라 제상시 발생되는 히터의 열기가 냉각기 상부에 마련된 팬의 구동으로 끌어 올려짐으로서, 냉각기의 착상된 성에가 녹는시간을 단축할 수 있다. 따라서, 제상시간을 단축할 수 있게 되어 그에 따른 전력소비량을 절감할 수 있는 이점이 있다.As described above, the present invention does not send the heat of the heater to the freezer during defrosting, thereby preventing frost on the shelves and foods of the freezer compartment, and preventing the food from being deteriorated. By being pulled up by the drive of the fan provided in the upper part of the cooler, the melting time of the frost of the cooler can be shortened. Therefore, the defrosting time can be shortened, thereby reducing the power consumption.
